Chapter Text
Human legends speak of a fearsome four-armed fire breathing oni: the horned lord of all evil spirits, the King of Curses. Though mortals treat their myths as cautionary tales, there are some who are wise enough to know that there is truth behind every story.
Even among oni, Ryoumen Sukuna, the King of Curses, is a fearsome name, not one to be uttered without the proper veneration. He is the undisputable strongest, an indomitable force greater than the might of the heavens. Satoru wants nothing more than to prove everyone wrong, and show that even gods can fall.
"I challenge you, Ryoumen Sukuna, for the title of the Strongest," the little oni announces with his head held high, approaching the horned tyrant lounging on his skeletal throne. The handful of slaves attending to the oni king freeze in utter disbelief and fear at the little upstart too foolish to realize that he is condemning himself to a painful death with his unspeakable irreverence.
Through strength and unmerciful brutality, Ryoumen Sukuna had risen to the top as the strongest demon in all of the land.
The title of the strongest often carried the burden of countless challengers seeking to make a name for themselves. It was futile, laughable, and almost boring at this point how they always fell at Sukuna’s hands. He hardly even had to try.
Just like many others, a voice disturbs his peaceful afternoon. As his nameless servant feeds him a bite of a luscious grape, Sukuna turns one of his eyes towards the small creature before him.
He’s but a boy. How amusing.
Sukuna doesn’t grant the supposed opponent a response. Instead, he bites on the grape hovering above his mouth. It’s plump and juicy, and much more interesting than the so-called challenger at his feet.
Satoru scowls at how he’s being blatantly ignored, at the complete disrespect. But he’s announced his intentions so if Sukuna decides not to take him seriously, then that will be his mistake.
While Sukuna’s attention is still foolishly on the grapes, Satoru fires a glowing red ball of pure energy at the tyrant, bathing the room in a blood-red light. The servants in the path of the red beam scream in fear, scrambling to get away. Satoru doesn’t wait for the dust to settle to launch another ball of red light at the oni king.
He doesn’t expect his attack to succeed— even Satoru isn’t foolish enough to believe Ryoumen Sukuna would be so easy to vanquish. But he hopes at the very least Sukuna will respect him as a proper opponent after his reckless display of immense firepower.
The floorboards are charred and there’s a stench of burning wood wafting in the room. The unsuspecting blast was enough to make Sukuna’s servants flee, abandoning their king. They will be punished later, Sukuna thinks idly. After he’s dealt with the little nuisance.
Sukuna endured minor injuries, but is quick to heal the shallow burns, skin replenishing within moments. It almost feels good, to have something reach his hardened skin. It’s rare, like a delicacy, although it was hardly enough to make him flinch.
The dust settles and Sukuna has a smirk on his face as he looks down at the challenger. He appears unscathed as he rests his chin on his hand. His red eyes lock on the vibrant blues of the boy before him. They’re beautiful.
“Hm.” He hums, tone full of amusement.
Satoru smiles back at him, so full of arrogance and youthful folly. Though the wounds did not last long, he still managed to hurt Sukuna. He had drawn the blood of a god.
"Did that hurt, my king?" Satoru says the title with so much disdain that it may as well be an insult. His eyes are glittering with delight, fueled by a fervor that can only be brought out from battle. He may have to look up at Sukuna now, but he'll make the King of Curses kneel before him soon enough and acknowledge him as his superior.
Red eyes narrow as they stare down at the young challenger. How arrogant. How delightful.
“Watch your tone.”
Most who dared use such a tone with the king had their life snuffed out right as the words left their lips. To insult him meant certain death.
However, the kid managed to land a blow on him, something most challengers fail to do. He has potential and the disdain in his eyes has piqued Sukuna’s interest.
In this world, strength reigns supreme. It’s the natural hierarchy, and Sukuna stands alone at the apex. A worthy challenger would be very entertaining.
How he’d relish in squandering the boy’s passion, to watch the fire leave his eyes when he’s faced with true strength.
Although interested, Sukuna doesn’t show it. He maintains his lazy stance, voice flat, almost bored sounding,
“You wish to challenge me, you say?”
“Obviously,” Satoru snorts. “I’m certainly not here to feed you grapes. What’s with that, by the way? Have you grown so complacent with your title that you’re too lazy to feed yourself?” He smirks insolently, not a shred of deference to be found in his demeanor.
While everyone had been raised to fear Ryoumen Sukuna’s name, Satoru had always been above that. Fear is for the weak, and fear itself is also a weakness. Satoru was born different, a cut above the rest. When he ran out of worthy foes who could match his strength, it is only natural that he seeks out even stronger enemies. Climbing up the hierarchy of strength until he reaches the summit, face to face with the King of Curses.
Only one individual can stand at the top, and for Satoru who has never known loss, he will either attain glory the likes of which has never been seen before, or die satisfied, knowing that he’s given his all.
Neither defeat nor death scare him, but he’s too young to fully understand either.
Without granting the boy a response, Sukuna flicks his wrist to unleash an array of slashes. Red stripes bloom on the boy’s pale arms from the unseen onslaught. “Then come at me, make this worth my time.”
The slashes sting but they’re shallow. Almost like a caress. Like Satoru is being teased with a fraction of Sukuna’s strength.
He’ll force Sukuna to give him a full taste of his powers. This time, Satoru’s attack comes with a blue tinge, pulling the contents of the room towards him. Wood comes loose from the foundation, fragments of bone flying off the morbid throne, swirling in the air. Satoru’s teeth clench with effort as he tries to draw Sukuna to him. To force him off his throne.
As the bones are ripped and thrust from his throne, Sukuna feels his own skin being pulled forward from a magnetic-like force. How curious.
“Fuga.”
A deep voice chants, and between his palms a ball of fire is formed. Sukuna plays with it for a moment, watching how Satoru’s power pulls at the flames like wind to a bonfire, threatening to burn everything in its surroundings. Sukuna flicks the ball towards the boy, his own power bringing the danger towards himself. The flames are jettisoned towards Satoru, igniting his yukata on fire with a roar.
Satoru’s eyes widen at the roaring fire careening towards him, but he is prepared for it. Sukuna’s unholy flames is what he is known for, and it would have been stupid if he sought out this fight without having some way to deal with them.
Even then, the heat is intense, like he’s being singed by the rays of the sun. The fire doesn’t reach his skin, which is protected by his impassable cursed technique, but Satoru still feels like he’s being burned alive, as though his flesh will slough off his bones like well-cooked marrow.
As he’s enveloped in the unnatural fire, he must admit that they’re strangely beautiful. Dancing in the air and flickering with warm light. They eat away at his yukata until it’s mere ash, then die off when there’s nothing left to burn, leaving the small oni naked and laid bare before the King.
He survived the fire but at the expense of much of his energy. Satoru gets the feeling that he’s still being toyed with, and for the first time in his short life there is a small trickle of fear in the back of his mind.
“Have you finally decided that I’m worth your time?” Satoru shakes away the fear, replacing it with his usual cockiness.
“Perhaps.” Sukuna says idly as he steps off his throne and saunters towards the boy. At almost 3 meters tall, the oni towers above him, engulfing Satoru in his massive shadow. Red eyes gaze down his naked body, smooth and unscathed by the flames. The cuts on his skin are pretty, and Sukuna wants to paint him with more.
Sukuna places a large hand on the boy’s bare chest and digs his claws into the skin. An intricate woven pattern of slashes rip through him, shredding the boy’s skin under his palm. It’s deeper than before and blood spills like a red stream down his torso.
“The cuts from cleave adjust themselves based on my opponent’s strength. Not bad, kid.” Sukuna says in a condescending tone as he removes his hand to admire the mess on Satoru’s chest.
Fatigued by the effort of keeping the flames at bay, Satoru can't stop Sukuna from cutting into his chest, and he gasps from how his skin is being shred apart. But he's smiling, despite the pain. Or maybe because of it. The blood loss makes him dizzy, light-headed, but in a good way.
"I don't need you telling me that to know I'm strong." He says that, but there's still a rush of pride surging through him from being acknowledged by the King of Curses.
“I can see that you think highly of yourself.” Sukuna hums as he digs a sharp claw into the fresh wound on Satoru’s sternum. The red is brilliant against his smooth, pale white skin. “It’s too bad you won’t make it to adulthood, perhaps if you weren’t so eager you could have been a worthy opponent.” Sukuna brings his blood soaked nail to his lips and licks the blood clean with his long tongue to taste the boy.
"What does it say about you to be bested by a child, then?" There's a mad glint to Satoru's eyes, almost self-destructive. Sukuna had willingly entered his proximity, giving Satoru a perfect opportunity for a point blank attack. Red light gathers at his fingertips, a massive burst of energy directed right at Sukuna's chest. The recoil of which makes Satoru feel like his bones are vibrating in his body.
Sukuna doesn’t dodge the attack and allows the boy to hit him directly in the chest. He’s curious about the strength of his power, how much he can be hurt by the young oni. The impact rattles his shoulder as he’s struck, and there’s a circular red burn mark on his chest. Sukuna grins.
“So you have a death wish after all.”
The king brings his hands in front of his chest, making a hand symbol like a tent with his fingers.
“Domain Expansion: Malevolent Shrine.”
Once the words leave his lips, a large structure resembling a Buddhist shrine rises behind him. The opening is like a giant maw and the roof is lined with horns. It’s decorated with bones, both human and animal in a gruesome and haunting display of might.
Satoru's confidence falters at this demonstration of power. He's never seen anything like this before, the landscape being molded, painted over with a hellish brush. The feat of a god.
"Is this supposed to scare me?" Satoru snorts, acting unfazed despite his pounding heart. The various bleeding cuts on his body. He knows better than to show any weakness. "We went from one shitty shrine to another."
“Such insolence.” Sukuna spits.
There is no way for Satoru to escape the barrage of cuts that rain down upon him. They slice his thin frame indiscriminately, lacerating his flesh in unmerciful strikes.
Arousal blooms within Sukuna as he watches the boy’s naked skin rip apart, spilling blood onto the floor and decorating his shrine. It’s a beautiful sight, and pain suits the arrogant child wonderfully.
It's impossible for Satoru to hold onto his insolence under the onslaught of slashes, cutting through even his cursed technique. He doesn't understand why he's unable to stop any of them, and he can't think through all the pain. All he can do is whimper pathetically, bleeding steadily until his legs give out.
How utterly shameful it is, to be kneeling before Sukuna. Satoru snarls at the humiliation, which stings so much more than any of innumerable cuts on his naked body.
Sukuna’s eyes droop at the sight of the boy kneeling before him in a puddle of his own blood. The lacerations are like a grotesque painting for Sukuna to admire, made even more beautiful by the boy’s pathetic whimpers.
It’s cute how Satoru tries to snarl, despite the futility. Sukuna wonders how much more it would take for the boy to cry and plead for his mercy.
The slashes relent for a moment and Sukuna hovers above Satoru’s tattered body. He grips the boy’s white hair and tilts his face so that their eyes meet.
“Do you still wish to show me how strong you are?”
Glaring back, Satoru spits at Sukuna, the glob landing landing on Sukuna’s cheek was more blood than anything else. The difference in their abilities was so much more insurmountable than he could have imagined, but he refuses to relinquish his pride.
If he’s still breathing he has yet to be defeated. Satoru gathers the last of his energy in a final attack. His swan song. A swirling maelstrom of blue light far greater than any of his previous attacks. As it flies towards Sukuna, Satoru’s vision blurs, the blood loss catching up with him. His body goes limp, held up only by Sukuna’s grip on his hair.
The attack is formidable, Sukuna acknowledges. It almost breaks through malevolent shrine, casting some of the decorative bones surrounding the maw onto the floor where they shatter. It’s destructive, and chaotic. Unfortunately for Satoru, he starts losing consciousness before it can do enough damage to Sukuna and break the domain.
Sukuna feels the boy’s weight grow heavy in his grasp. He clicks his teeth and slaps Satoru across the cheek with the back of his free hand.
“We’re far from finished.”
Satoru's eyelids flutter open from the slap, but his sight is too hazy for him to see anything even with his eyes open. Sukuna is still alive while his body is nearly broken. At least for whatever the wretched King of Curses has planned next, Satoru will be too unresponsive to care. He can't see how much more pain can be inflicted upon him when it already feels like he's been flayed apart, every nerve on fire. The only other thing Sukuna can do at this point is to kill him, and dying at his hands is at least an honorable way to go.
Sukuna drags the boy by his hair towards the shrine. A trail of blood seeps out from his limbs making a mess on the floor for Sukuna’s servants to clean later.
Unceremoniously, Sukuna lays the young oni onto his stomach on the tongue of the maw, facing inside the horrid depths of malevolent shrine. He hopes the cuts sting as he’s bent over the wet muscle, ass presented to Sukuna like an offering.
Satoru moans weakly in pain as he's put on his stomach. He wonders if he will be fed to the shrine, whose gaping maw he has been placed in. The meat of oni is unpleasant and tough, nothing at all like eating a human, but Satoru's still young enough where his flesh would be tender.
He hopes he gives Sukuna indigestion.
Sukuna splays a hand over the small of Satoru’s back as he removes the belt from his kimono. The fabric falls open, revealing black tattoos that run down his chest and a large mouth in his abdomen.
A twin pair of throbbing cocks spring erect, red and angry as they twitch above Satoru’s soft, round cheeks. More frightening still, are the needle-like barbs raised underneath his glistening cockheads.
“As a reward for your display of strength, I’m going to give you my seed.”
Confused, Satoru peeks over his shoulder to look behind him. His eyes widen when he sees that Sukuna has undressed, at the wide mouth on his stomach and his two hard dicks. Satoru has never seen anyone’s penis aside from his own, and there’s something terribly obscene about Sukuna’s, each one so much larger than his.
“What… what are you…?” Though Sukuna looks ravenous, it doesn’t seem like he’s going to eat him. The uncertainty is what scares Satoru; the unknown way in which Sukuna intends to play with him before he dies.
The realization that the kid is a virgin rushes through Sukuna in a euphoric wave. How delightful to debase something so arrogant yet pure and naive.
“I’ll teach you what happens to the weak, little lamb.”
Sukuna’s voice lowers and he grips Satoru’s small hips in his hands. If he presses harder, the bones could shatter under his grasp. The difference in their sizes should make this apparent enough to Satoru, and keep him in place.
Sukuna leans against Satoru’s bare flesh, releasing the tongue on his abdomen to lick between Satoru’s cheeks, smearing saliva on his perfect little hole.
Though he is a prodigy in combat, Satoru’s worldly knowledge is severely lacking as a small oni still so far from reaching adulthood. His face burns as he is licked there, something so humiliating about the act.
His rebuttal about not being weak dies in his throat as a broken whine. Trying to speak only makes his mangled body throb in pain, and he’s frozen in place in mortification. Satoru knows he’s going to be eaten alive, but is it really necessary for Sukuna’s tongue to be where it is? He shuts his eyes as though it’ll help block out his humiliation. He’s not surprised that Sukuna intends to drag out his death, but he can be brave about it until the end.
The boy’s whine is like a melody to the king of curses, and he hopes to orchestrate more, to have him sobbing and begging for mercy underneath him. The tip of Sukuna’s large tongue prods at Satoru’s entrance then pushes past his rim to force him open. The taste is divine as his tongue worms inside, clenched tightly from the resistance. He’ll have to stretch the boy a bit, or else he’ll break his new toy too quickly.
Whatever Sukuna is doing to him feels weird. Wrong. Satoru wants to squirm away, but there’s nowhere for him to move, his one side pressed against the shrine’s tongue, and his other trapped by Sukuna’s tongue inside him.
He doesn’t like this feeling. Satoru’s legs flail in an attempt to get Sukuna to stop. Though his eyes prick with tears from how much it hurts to move at all, he’d rather feel pain than the strange sensations Sukuna is forcing upon him.
Sukuna begins to rock his hips, thrusting his tongue inside to stretch the boy's tight entrance. The grip around him is heavenly as Sukuna licks along his walls to force them to accommodate the girth of his tongue.
“You’re tougher than you look, I’d say you’re even enjoying this. But where’d that bratty mouth of yours go? Don’t be shy, I want to hear how much you like it.”
“You’re disgusting!” Satoru snarls, but it comes out weaker than he’d like it to. “It’s gross, whatever you’re doing to me…” his face is hot as he struggles to find the words for something he doesn’t understand. His head feels fuzzy and his throat dry, and Satoru hates how he can’t do anything but take Sukuna’s large tongue prodding inside him, filling him up.
“What kind of king are you doing something this disgusting?” Satoru demands after too long of a pause when he was only capable of whining and choking on air.
Satoru’s bratty tone is entertaining to Sukuna, and only makes him want to break the kid further. So many fall before his feet in fear and reverence.
Yet this young child is defiant before the might of a god, taking humiliation with pride and resistance. Such arrogance should only be reserved for the truly strong, and Sukuna can’t help but wonder how formidable the young oni might be once he grows.
“I see you haven’t learned to address your king properly, yet.”
Sukuna drags his claws down the kid’s back, creating red stripes on his skin. The blood beads out from the wounds and Sukuna collects it to smear along his hardened cock.
He hisses as he jerks himself with his bloodied fist, “Beg for it, and i’ll consider sparing your worthless life.”
The pain on his back is, at least, familiar to Satoru. He hopes that it means Sukuna will be hurting him in a way that he understands. He doesn’t dare look behind him again, his stomach churning from the slick sounds he can hear. He has no desire to see how Sukuna plans to break him, nor what cruel expressions must be on his face as he brings Satoru to his lowest point.
“As if I’ll beg,” Satoru sneers. He’d die if that means his pride remains intact. He grits his teeth as he endures yet another wave of pain, the newest wound on his back throbbing the hardest. He’s not sure how much longer he’ll be able to stay conscious for, but he won’t give Sukuna the satisfaction of breaking his spirit.
“Suit yourself.”
Sukuna swirls his tongue for a generous lick before removing it. Spit connects from the boy’s slit to the muscle in a sloppy mess before he swallows it all.
Then, without warning, Sukuna breaches into the boy with his bloodied cock, bullying past the resistance to bottom out in one harsh thrust.
He tilts his head back and moans, low and loud as he’s engulfed in the virgin’s tight heat.
Satoru forgets how to breathe as he’s speared onto Sukuna’s cock, his mouth hanging slack. Even though he has been loosened on Sukuna’s tongue, Sukuna took him by surprise, and his every muscle is drawn tight as he’s violated for the first time.
He cries out at the never-ending intrusion, the pain in his backside so unlike any pain he’s endured before. His fingers claw at the shrine’s tongue as he tries to buck away from Sukuna’s hips, but it does nothing to stop him.
“Sukuna!” Satoru sobs in agony as soon as his lungs start working again. “No, stop…!” He only manages to get a few words among his screams of pain and discomfort.
The boy’s sobs and crying of Sukuna’s name only rile him further. He’s so tight like a vice that Sukuna has to force his cock into unwilling walls with a violent thrusting of his hips. The barbs drag along his walls, cutting every time he pulls his cock out. He shows no mercy as he fucks into the boy violently, slapping against his cheeks until they’re red from the impact.
“I thought you were above begging, are you really this easy to break? What a disappointment.” He spits between labored breaths.
It feels like his insides are on fire, and Satoru is still in utter shock, uncomprehending of what’s happening to his body. Everything hurts, and there’s an awful pressure in his stomach that’s curving outwards with each of Sukuna’s movements.
Satoru starts slipping in and out of consciousness, his eyes rolling into the back of his head. His skin growing colder. He wanted to die battling the King of Curses, not like this. Whatever this is, it’s shameful, and it makes Satoru want to curl up into a small ball.
Sukuna seeks his pleasure selfishly, ripping apart the boy’s hole as his oversized cock thrusts in and out of him. Blood seeps from his damaged walls, coating Sukuna in red and making the glide easier for him.
When he realizes that Satoru is losing consciousness, he smacks his hand across his ass cheeks with a loud crack that echoes through the shrine. “Stay with me, enjoy your reward.”
Satoru is bleeding in new places. Places he didn’t know he could bleed from, and which he doesn’t want to think deeper about.
If he still had his senses about him, Satoru would have given some retort about how any of this can ever be considered a reward Instead, he gives a startled moan at the hit.
“What is… what are you—“ he whimpers brokenly, sounding for the first time like the child he truly is. He just wants this to be over already.
“Don’t tell me an arrogant brat like you doesn’t know what this is. What you are to me now.”
Sukuna’s voice is hoarse and strained as the pleasure soars through his veins. His second cock slides between Satoru’s cheeks as he thrusts relentlessly, raised barbs slicing the thin skin of his slit until blood is dripping onto the maw.
“A nameless hole for my pleasure, nothing else.”
Satoru doesn’t like this, how he’s being hurt and degraded in novel ways. He knew that Sukuna enjoyed inflicting pain and suffering onto others, but he didn’t know what it meant to be used for Sukuna’s pleasure until now, and he hates it.
Tears stream down his face as he’s forced to take this relentless assault. His insides are being torn apart on Sukuna’s too-big penis, which is being used as a weapon on his vulnerable flesh.
The sound of the boy’s cries has Sukuna’s climax building towards the edge. Sukuna’s barbs shred the inside of Satoru’s walls like a grater when he rips his cock out from Satoru’s abused hole. With a guttural moan, he spills onto the cuts on his back. Cum seeps into the wounds, decorating his back in red and white.
With Sukuna’s penis no longer inside him, all the cuts in Satoru’s hole throb painfully as they’re left exposed to the cold air. The wounds on his back sting as well from the liquid dripping into them. Satoru feels disgusting, and the space between his legs hurts so much.
He’s still not entirely sure what had happened.
Sukuna wraps his kimono around himself with a dignified energy befitting a king.
“Once you’ve healed, come challenge me again.”
Malevolent shrine disassembles and the boy crumbles onto the charred ground. Sukuna’s servants pick up his mangled body and escort him to another room further in Sukuna’s home.
Satoru is fading into unconsciousness again, his mind overloaded by all his pain. But he still manages to pick out Sukuna’s parting words to him. Words that he’ll never forget.
He’ll get stronger, and challenge Sukuna again, but it won’t be out of misplaced pride. No, it’ll be as payback for the humiliation he suffered today. Hatred is what is burning in his thoughts until he passes out entirely, his body limp and cold as he’s carried away by servants.
Satoru is taken down an elegant hall towards a bath. There, he’s washed and his wounds are tended to by Sukuna’s confused servants. He’s never had them care for one of his opponents before, but they know better than to ask questions of the oni king. Afterwards, Satoru’s limp body is laid down on a futon in the center of a tatami room.
Days pass.
Sukuna carries on with his daily activities: training, fighting, plundering and eating the finest foods of the era. He doesn’t visit the boy, though images of his blue eyes linger in the back of his mind.
Satoru doesn't wake for days, and when he does, he can tell he's still somewhere within Sukuna's shrine. He's resentful of how he's still alive, as though he isn't even worth killing, and he's even more insulted when Sukuna never visits him. Like his existence doesn't matter at all, and all he is to Sukuna is yet another nameless challenger.
He's going to get stronger. Satoru is now aware of the wide gulf in their strength, but he'll make Sukuna regret leaving him alive. The small amount of childish naiveté that he had is gone now, replaced by deep hatred.
He will be the one to kill and eat Ryoumen Sukuna.
Sukuna doesn’t see the boy leave, but is vaguely aware of his missing presence from his home. He idly wonders if he will see the young oni again.
Chapter 2: Chapter 2
Chapter Text
Pink cherry blossoms bloom around the shrine, decorating the grounds with petals to mark the oncoming of spring. It’s a lovely sight when the magnificent red pillars of the shrine are surrounded by pink and white blooms.
Throughout the last few months, Sukuna has kept busy maintaining his status as the strongest. Countless challengers have fallen at his feet, many of which were unremarkable.
On a random spring day, Sukuna walks throughout his pristine garden, observing the blooming flowers. They’re delicate and fleeting, a beauty which never fails to move him. He finds a quiet bench on which to read poetry and enjoy the scenes of his land.
Walking away from Sukuna’s shrine was painful, but Satoru scurried away like a dog with its tail tucked between its legs. His pride was gravely injured, and each step hurt from the soreness in his ass left behind from being used for Sukuna’s pleasure.
He spends the following months seeking out punishing fights, challenging anyone with even the slightest potential he crosses paths with. None of them can hold a candle to Sukuna, but through these opponents Satoru gains a firmer understanding of his powers.
And of his limitations.
One of his opponents ends up leaving him in a puddle of his own blood, but when he rises again with renewed vigor and greater power than before, Satoru knows then that he’s ready to face off the King of Cursed again. This time, he knows how to win.
He finds Sukuna not perched on his skeletal throne, but instead reading peacefully under cherry blossom trees. Satoru scoffs as he announces his presence.
"Has the great Oni King grown so complacent in his title that he spends his days lazing about and reading?"
Red eyes peek from above the book to stare down at the little oni. It’s for only a moment, before his gaze casts back to the words on the page.
“It’s a great privilege to read in a beautiful place such as this. A lowly being like yourself couldn’t possibly understand.”
Satoru hates how Sukuna blatantly ignores him each time they've interacted with such infuriating arrogance.
"I'll read once you're dead, when the tales of your death by my hands are transcribed onto parchment."
“That so?” Sukuna chuckles in amusement. He licks the tip of his finger before idly turning the page.
Satoru glowers unhappily. "Fight me already! Or are you scared that you'll lose." He's not sure how effective taunting will be in goading Sukuna into a fight, but if Sukuna continues to ignore him he'll take that as an invitation to attack him anyway.
“You haven’t learned anything.” Sukuna mocks with a dangerous edge to his voice. He’s still looking down at the pages, but there’s a sinister smirk weaving across his lips. “Perhaps you missed my cock, is that it?”
"I don't know what you mean by that." Satoru's cheeks are warm because he's certain that there's something dirty about Sukuna's words. "But I have learned plenty since I challenged you the first time."
“Don’t tell me you’ve forgotten the feeling of my cock inside you. How I filled you and allowed you to be close to a god for a moment.”
Sukuna closes the book and places it beside him. His red eyes bore into the young oni with a hungered expression.
“Isn’t it empty now, after I carved you to the shape of me? You must miss it.”
Satoru's skin crawls when he understands what Sukuna means, feeling sick at the memory of what had happened to him. He almost shrinks away at the hungry look Sukuna gives him, as though he's already planning on violating Satoru again.
"I'm going to kill you," he spits hatefully, devoid of the cockiness he had earlier.
“Oh you are?” Sukuna chuckles darkly. He enjoys the hateful tone in the boy’s words. Hatred is an excellent motivator, and he imagines the boy now needs to avenge his pride and honor. The added rage could make for a better fight, and even more entertainment.
“How badly do you wish to challenge me again?”
"How badly do you think?" Satoru rolls his eyes. He'll do anything to fight Sukuna again, and his pride demands for their match to be honorable. He won't resort to lowly tactics like attacking Sukuna when his back is turned.
“You’ll have to earn the right. If you entertain me, I’ll consider your challenge.”
Sukuna stands from the bench and stalks towards the young oni. Hovering above, he looks down at him with a wicked grin.
Satoru swallows from how easily Sukuna is able to tower over him, likely double his height, but he's quickly able to school his expression.
"I'm here to fight you, not act as a courtesan. What, do you want me to sing and dance for you?" Satoru asks sarcastically.
“You’ll fight me only when I allow it.” Sukuna returns to his bench and sits leisurely with his legs spread. “Come here, and kneel before me.”
"Why should I kneel before you?" Satoru demands indignantly. "You haven't deserved my reverence." He ignores the fact that Sukuna has beaten him in combat once before already.
“Then leave, I have more interesting things to do.” Sukuna says lazily as he once again picks up his book.
Frustrated, Satoru balls his fists as he stands there foolishly, not knowing what to do. He can just attack Sukuna anyway, but that doesn't feel right to him. Neither does kneeling before the Oni King, but...
"Fine," he spits, getting on his knees between Sukuna's spread thighs. His body is warm with embarrassment, and the nagging feeling that there's something dirty about this act as well.
“Good.”
Sukuna takes a moment to drink in the sight of the boy kneeling before him, where he belongs. He places two fingers under Satoru’s chin and tilts it so that he can look into those blue eyes.
“I’ll teach you how to show proper reverence for your king.”
"Is there something wrong with the way I kneel?" Satoru glares at Sukuna, unhappy with his current position. "Would you rather I kowtow?" he offers dryly. "I won't do that."
“I’d rather you use that mouth of yours for something more useful.”
With one hand, Sukuna slides the folds of his kimono to expose his cocks. He then grips onto Satoru’s chin harder, as if he would crush the bones, to pry his jaw open and pulls the boy towards his lap.
“If you can please me, I’ll consider fighting you.”
Satoru pales as he takes a proper look at Sukuna’s dicks, his thighs squeezing together as he subconsciously tries to protect himself from them. They’re too big, and the spines beneath the head of each of Sukuna’s penises makes Satoru swallow in fear.
“What do you mean please you?” his voice is small, and he tries to back away from Sukuna but the other his holding him too tightly for him to leave.
Sukuna presses the tip of his highest cock against the boy’s soft lips. Feeling generous, he offers some advice, “Give it a kiss, and use your tongue like sucking on a candy. Be playful, and don’t be shy.”
That... doesn't sound too bad, and if this is what's needed for Sukuna to agree to fight him...
Satoru timidly kisses the head, looking up at Sukuna the entire time as though asking for guidance. He's never kissed anyone before, and it makes him feel weird to think of this as his first kiss.
“Good, just like that.” Sukuna releases the kid’s jaw in favor of running a hand through his white hair. His red eyes droop as they look into those sapphire blues, “Wrap your lips around it.”
Satoru is not sure what kind of pleasure Sukuna is deriving from this. Maybe this is a new way the Oni King has invented specifically to humiliate him. At least it’s not as degrading as what Sukuna had done to him when Satoru failed to kill him.
He closes his eyes in a tight grimace as he eases the tip of Sukuna’s dick into his mouth, stopping right before the barbs that poke at his lower lip.
The boy’s lips are soft like a caress as they wrap around his cock. Sukuna cradles the back of his head in his hand, holding Satoru in place. He’s enjoying guiding the boy slowly, and how submissive he’s already being for his king. “Go deeper, take as much of me as you can.”
Satoru shakes his head as best as he can with the way Sukuna is holding him. He doesn’t want those painful barbs inside his mouth, and he tries to pull his lips off of Sukuna’s dick entirely. Satoru feels that he’s debased himself enough already, and that he’s earned his fight.
Sukuna clicks his teeth and holds tighter onto Satoru’s head, not letting him get away. His claws dig into the boy’s skull slightly, reminding of the danger before him. “Giving up so soon?”
Satoru only struggles more, desperately trying to get away from Sukuna’s penis. He doesn’t want to do this anymore, and he doesn’t want those spikes anywhere near him ever again.
Sukuna maintains his grip despite Satoru’s struggling. His voice is low and almost sweet, contrasting his actions and the lewd scene at hand, “You were doing so well before, don’t disappoint me. Here, I’ll help.” With that, Sukuna pushes his hips forward, guiding his cock further into Satoru’s small mouth.
Hissing, Satoru does the only thing he can think of to escape the situation. He tries to bite down on the offending appendage, but it's hard to do properly with how wide his mouth is being spread apart. Still, he can't imagine that his teeth dragging against such a sensitive organ can be pleasant, and he glares defiantly at Sukuna.
Sukuna growls low in his chest and pulls his cock from Satoru’s mouth, ripping the sides of his gums with the erect barbs. There’s an unreadable expression in his red eyes as he stares down at the kid kneeling before him.
“Insolent brat, unable to perform even the simplest of tasks.”
Sukuna whips his head harshly and releases his grasp.
“Get out of my sight.”
Satoru coughs as he's let go, his eyes stinging from his bleeding gums. The taste of his own blood sits heavily on his tongue.
"But... What about our fight?" He feels stupid just asking the question, and his face is uncomfortably warm.
“You haven’t earned the right to challenge me.”
Sukuna says simply as he tucks his cocks away inside his kimono. It’s uncomfortable with how hard he is, still twitching from the phantom feeling of the boy’s sweet lips stretching around his length.
However, Sukuna acts unfazed and turns his attention away from the young oni. His expression reads one of boredom.
Satoru remains kneeling with an angry flush on his face, his lips pulled in a childish pout. He feels like all the humiliation he just endured was for nothing if he gets turned away now.
Pulling a face, Satoru looks away from Sukuna, mumbling, “I can try again.”
The boy’s pout is cute, and stops Sukuna from outright kicking him out of the garden.
“Tell me why I should let you try again?”
“I’ll do better this time,” Satoru says quietly, still unable to look directly at Sukuna. He swallows thickly, and the coppery taste of blood slides down his throat.
Sukuna smirks, “Now that’s more like it. Come here, show me how badly you want this.”
Not entirely sure what to do, Satoru hesitantly tugs at Sukuna’s kimono to take out his cocks. He cowers a little at the peak he gets of them through the fabric, but remains determined. He really wants the fight.
Sukuna leans back on his hands, fully erect and presenting himself to Satoru. The boy looks even smaller kneeling before the massive girth of his throbbing cocks. “Show me how much better you can do.”
Satoru leans up to the closest dick and bites his lip. He presses a light kiss on the shaft, remembering what Sukuna had instructed him to do the first time. Maybe he can get away with just kissing it.
Sukuna groans, feeling teased by the boy’s adorable shyness. “It’s going to take more than that. Take me in your mouth and suck on it, like a candy.”
Satoru sulks a little, disappointed that his plan isn't working. He stares at Sukuna's penis, trying to reassure himself. No matter how he looks at it, there's no way that it looks anything like candy. He closes his eyes and tries to think about his favorite sweets as he puts his lips on Sukuna's dick.
Sukuna hums approvingly and brings his hands back to card through Satoru’s hair. The strands are soft, almost delicate, on his large rough fingers. “You’re being so good for me. Now, go deeper, as much as you can.” He coaxes the boy, wanting to see how far he’ll go for the fight he’ll inevitably lose again.
Once again with the barbs pressed against his lips, Satoru feels fear piercing through him. But for some reason, he doesn’t want to disappoint Sukuna. Like he has something to prove. And the praise he received from the oni king made him lightheaded, his body warm.
He allows the spines past his lips, despite his racing heart, looking up at Sukuna the whole time for validation.
Although inexperienced, the boy’s mouth is soft, and so warm around Sukuna that he can’t help but moan. There’s something wonderful about debasing the innocent and pure, especially this young oni with the fiery passion in his eyes.
The way he looks up at Sukuna sends a shiver down his spine, and he wants to see those blue eyes red with tears.
“Deeper.” He instructs between labored breaths. “Put your hands around the base and try to meet it, going in and out.”
Satoru is relieved to find that the barbs didn’t hurt as they went inside his mouth, so he takes Sukuna a little deeper, another row of barbs sliding past his lips.
He wraps a hand around the base of Sukuna’s dick as instructed with a sharp inhale at how his fingers can only envelop roughly half the circumference of the shaft.
Satoru wonders how he is making Sukuna feel. If Sukuna’s penis experiences things differently than his own, because of how much thicker and longer it is. Although Satoru has never really touched himself down there, except for when he needs to pee.
Sukuna enjoys how the boy’s little fingers can hardly wrap around his length and twitches inside his mouth, spilling a bead of pre onto his tongue.
“Let me demonstrate. Relax your throat for me.”
Sukuna pushes his hips forward to press deeper down Satoru’s throat. Once engulfed in the wet heat, Sukuna shudders and pets the boy’s hair encouragingly. The red of his eyes are shadowed by blown out pupils as he admires the way the boy’s lips stretch around him as they struggle to wrap around his length.
Satoru feels ticklish from the way Sukuna's dick is nudging against the back of his throat. But when he presses even more insistently, trying to demand entrance, Satoru's eyes water and he starts to panic a little. It feels wrong, and he wants to gag, but it's hard with how his small mouth is stuffed full of Sukuna's length.
He tries to relieve the pressure by pulling away, just a little, from Sukuna, but whimpers in pain as that causes the barbs to drag the wrong way, scraping against his tongue. Satoru's eyes are watery as he sees that he's been trapped, and the only way to go is forward.
“That’s it.” Sukuna grins when those blue eyes are glistening with tears. They look even more magnificent against his reddened face, almost haunting in their brightness. Slowly, Sukuna pulls out, dragging the barbs along Satoru’s tongue.
“Now, let me help.”
Without warning, he plunges back down the boy’s throat, and starts fucking into his mouth more deliberately. He wants Satoru to gag, and to see tears fall from his beautiful eyes. He didn’t get to see his expression before, and he will make up for that.
Satoru feels like he’s been fooled somehow into being an architect of his own destruction. He chokes when Sukuna pushes too deep down his throat, tears pricking his eyes and his nose getting snotty. He pushes against Sukuna’s thigh trying to escape, Sukuna’s other dick hitting his cheek during his struggle. But any outward movement results in the spikes pulling painfully at his flesh, and his gasp of pain only opens his throat further for Sukuna to abuse.
It was cute when the boy was willing and meek for him, but Sukuna needs more. The boy’s attempts of escape hardly register as he seeks his own pleasure selfishly within the tight, warm mouth beneath him. “Use your hands on the other one, don’t leave it neglected.”
Satoru's grip around the dick bullying its way inside of his mouth is already loose, and he's crying too much to pay any attention to what Sukuna's saying. He's uncomfortable, his tongue starting to bleed from the barbs scraping against it. It's also hard for him to breathe with Sukuna's dick in his throat, and he can't stop gagging each time it pushes inside.
"Stop," he wants to say, but it comes out as a small muffled sound.
Sukuna grunts in frustration. He wraps his fist around both lengths, and when he pulls out, he’s fighting to shove both cockheads into Satoru’s bloodied mouth.
Satoru tries to keep his lips pursed together, shaking his head to refuse the intrusion. Each of the dicks were already intimidating, but seeing them together makes Satoru’s heart drop to his stomach.
His knees hurt from kneeling, and he wants to go home.
Sukuna pinches Satoru’s chin with two fingers and pulls down. The boy’s lips split and bleed into his shaft as they’re stretched impossibly open to take the massive girth of his throbbing cocks.
As Sukuna forces the entry, he can feel the boy’s jaw break and unhinge completely.
“A perfect little cock sleeve.” Sukuna spits meanly as he bullies into the back of Satoru’s throat. “Try not to die on me.”
Satoru screams as his jaw breaks, but the sound is cut short by Sukuna’s dicks stuffing his throat and cutting off his airway. He can’t breathe, choking on the dicks as well as his own blood and spit, and his head is spinning with pain. He’s finding it hard to stay conscious, unable to fight back against Sukuna in any way.
Sukuna cums to the sound of the boy’s scream, spilling his hot seed down his throat in a violent rush. He lingers a moment in the warm wetness of blood, spit and cum before easing out slowly.
“You’ve done well to please me.” Sukuna praises as he admires the ruined state of the young oni. “I’ll take care of you after this.”
Satoru is barely aware of Sukuna speaking, his body limp with his head resting on Sukuna’s lap. He’s left as dazed and confused as he had right after their first fight, like he’s been violated in some way. He’s in so much pain and he whimpers as he sniffles away the snot coming out of his nose.
Sukuna made him feel small and vulnerable again, and he hates feeling that way.
Sukuna lifts the boy so that his head is resting on his chest, leaving a wet mess on his kimono. He wraps his arms around Satoru and stands up, allowing the boy to be weightless against him.
The garden is peaceful as Sukuna walks back to the shrine. A heron flies over the lake and he pauses to admire it, enjoying the warmth of the boy against his chest.
Once back inside the elaborate walls of his shrine, Sukuna hands the boy over to his servants to tend to his wounds, just like before.
+
When Satoru comes to, his body feels stiff in a way that suggests he has been asleep for longer than a day. He doesn't like how familiar of an experience this is becoming after encountering Sukuna. He's even in the same room as the first time, except this time, he wasn't successful in actually challenging Sukuna at all.
Sukuna played him for a fool, and Satoru hates him all the more for it. He angrily gets up and storms out of the room, despite the lingering pain of his mouth to seek out Sukuna and kill him.
Sukuna hears the angry shuffling of Satoru’s feet on the hardwood before he sees him. He leans on his throne with his chin in his hand and waits with a small grin.
Satoru stomps up to Sukuna's throne and hurls a ball of red energy at Sukuna the moment he sees him, right at his stupid, smug face. He doesn't care about an honorable victory anymore, he just wants that oni dead.
Instead of letting the blast hit him, Sukuna leaps from his throne with an inhuman quickness, dodging it. The blast collides with the display of bones behind him, shattering several skulls which fall to the ground like glass.
The oni king approaches the boy, a grin still plastered on his face.
“So you’ve finally come for our rematch? Good, I was looking forward to it.”
Even though Satoru didn’t manage to hit Sukuna, the destruction of the throne brings him some satisfaction.
“You lied to me,” he accuses angrily, not realizing how much he sounds like a kid throwing a tantrum. Satoru fires off another attack, his face red with humiliation and fury.
“How did I lie? You succeeded in pleasing me, but passed out before our fight could begin.”
The boy’s attacks are unskilled and chaotic, much like a child blind with fury. Sukuna is calm as he dodges, carefully watching the direction of the blasts and moving out of the way.
“We’re fighting now. But if you keep acting without thinking, you’ll go down fast.”
Satoru pushes down the bubbly feeling from hearing Sukuna admit that he did please him in favor of continuing his string of attacks.
He’s as upset with Sukuna as he is with himself, for falling for Sukuna’s sweet words and walking straight into his trap. It won’t happen again, Satoru swears to himself.
Sukuna rushes before Satoru and grabs his small wrist in his hands, stopping his blind, relentless attacks. “Focus. At least make the battle worthwhile.”
"Don't touch me," Satoru hisses. "And why should you care to help me anyway?" Still, he takes a deep breath and focuses his anger, and his next attack is more potent than the previous ones, fueled by his rage rather than diluted by it.
Sukuna steps a few feet away from Satoru and looks down at him with a blank expression. Two of his arms are crossed, and the other pair are at his hips.
“Because I thought you had potential.” Sukuna states, noticing the stronger red glow of the boy’s attack. If they keep this up, the young oni could become a worthy opponent someday, he hopes. “If this battle isn’t worth my time, I’ll simply squash you and find another to entertain me.”
Satoru hates that any small amount of praise Sukuna has for him affects him at all, but how can it not? Sukuna is the King of Curses, recognized by all to be the strong without peer. Of course being recognized by him is meaningful, and it's part of why Satoru challenged him to begin with.
His reasons for wanting to kill Sukuna has become a lot more personal since, but he can't rid himself of the admiration he holds for Sukuna's power.
"I'm sure you'll find your last battle to be more than worth your time," Satoru spits out, still overconfident as always. He has not been entirely shed of his youthful folly.
It’s amusing how the boy remains arrogant, almost unfazed despite the utter debasement he experienced under Sukuna’s hands, twice. He wonders what it would take to truly break the boy, and how much stronger he might grow as a result.
Sukuna chuckles a little kuku as he unleashes his first attack, a barrage of slashes which rip across Satoru’s broken jaw.
Satoru scowls at the clearly targeted attack, like Sukuna is rubbing in what he had done to him. He knows Sukuna is trying to throw him off guard, but he doesn't allow it. Staring down the other oni, Satoru uses what he has learned in between their duels and heals the wounds. He hadn't returned to challenge Sukuna with nothing to show for.
Sukuna watches as the wound heals with interest. It’s impressive the boy has learned this skill at such a young age.
“How fast can you heal?” He asks before unleashing a larger, faster barrage of slashes which rip across Satoru’s limbs and torso. “How well can you control it?” He’s curious, testing the boy as he rains down a vicious stream of knives.
Satoru grits his teeth at the onslaught of cuts, unhappy that he's now forced on the defensive. He's able to close up many of the slashes, but they come faster than he can heal, and he can't attack while he's using all his energy on healing.
He had thought that this new ability will be what will allow him to turn the tide on Sukuna, but victory is not that easy. Even then, Satoru remains determined.
“I see, still unrefined.” Sukuna comments as the slashes relent. “It’ll take a while before you can withstand my attacks.”
Satoru sees the slashes relenting as a window of opportunity. He unleashes another attack at Sukuna, but this time even he can tell that it's too weak. He has been drained healing all the slashes Sukuna left on his body, and his clothes are in bloody tatters.
“Too bad.” Sukuna says, an edge of boredom in his tone after dodging Satoru’s weaker attack. “Do you wish to be beaten again, or are you done?”
“I won’t be done until you’re dead,” Satoru spits. Even if he doesn’t win this fight, he’ll just keep coming back again and again, stronger each time.
The possibility that Sukuna may just end his life instead doesn’t cross his mind.
“Have you learned nothing?”
Sukuna stands before the kid and bonks with a tightly gripped fist. The force alone should rattle his skull, maybe knocking some sense into him.
The force of the hit brings tears to Satoru's eyes, and he feels more like a child being reprimanded than someone suffering the blow from their enemy.
"When are you going to learn to take me seriously?" He tries not to make it sound like he's pouting but he's not very successful at that.
“When you stop having a reckless death wish and battle wisely.”
Sukuna says honestly as he swipes the tears from under Satoru’s eyes. In a moment of indulgence, he licks the tears from his finger to taste the boy.
Satoru pulls a face watching Sukuna lick his tears.
"Gross," he says without thinking any better of it. "King of Curses, more like King of Freaks."
Sukuna smirks. It’s astounding how the small child before him has the nerve to insult the towering, monstrous king with such petty insults, despite being covered in scars and blood.
“Maybe I am. What does that make you?” He says crudely as he flicks at Satoru’s exposed nipple through a tear in his shirt.
Satoru scowls as he tries to cover his nipple with his hand even though he's not a girl. He didn't like the way that felt.
"That makes me the one who'll kill you." He still hasn't forgotten his hatred, even if his ability to fight is currently impaired.
“Yeah, yeah.” Sukuna shoves Satoru’s hand away to expose his nipple once more. It’s so cute, like a dainty flower bud, soft and pink. He flicks it again, watching it harden under his claws.
Satoru’s face burns. Sukuna is being weird again, and this time it’s also making him feel weird.
“Stop that,” he hisses, turning away from Sukuna so he can’t keep touching his nipple.
The flush of red on the boy’s face is all Sukuna needs to see. He grabs the boy’s shoulder and turns him back to face Sukuna. This time, he pinches his nipple between his large, clawed fingers with a little grin.
“Make me. We’re fighting, right? Like you wanted.”
Satoru has to cover his mouth to quiet himself. He’s starting to feel funny, like he’s sick or something.
“What are you doing?” he mumbles through his fingers. He doesn’t have the strength to escape Sukuna’s grasp.
Sukuna doesn’t answer as he rubs the hardened bud between his fingers, transfixed on Satoru’s embarrassed face. He cuts a hole through the other side of his shirt, freeing the other nipple and starts rubbing circles on it with the pads of his fingers.
Satoru’s knees feel wobbly from what Sukuna is doing to his nipples. He hadn’t known they were this sensitive, and that Sukuna knew about this weakness before he did.
“S-stop,” he says weakly, taking his hands off his mouth to try and push Sukuna’s fingers away and protect his nipples.
Sukuna takes advantage of the boy’s weakened state and pushes him down onto his back. He straddles him with both knees on either side of his small frame and begins pulling his shirt off overhead.
Satoru’s body freezes when he’s pushed onto the ground. Sukuna’s weight on top of him reminds him painfully of what had happened after their first fight, and he’s suddenly too scared to move. A cold sweat makes his skin glisten.
Sukuna removes the boy’s tattered shirt with ease and runs his hands along his small, scarred chest. His weight isn’t fully on Satoru, lest he crush his thin bones. The boy looks so tiny underneath his imposing form, barely larger than one of Sukuna’s thighs.
Sukuna’s hands wander freely on the boy’s soft skin, teasing his nipples and cupping an undeveloped breast. What he feels underneath is just skin and bones. The boy really is frail, young and naive.
Satoru is undeniably scared being pinned underneath Sukuna’s immense weight. When standing, their size difference doesn’t seem nearly as intimidating, but now he gets the impression that Sukuna has to be careful not to break him.
He’s uncomfortable with how Sukuna is poking and prodding at his body, like he’s inspecting it or something. But Satoru doesn’t have much choice other than to subject himself to Sukuna’s touches, which he bears with gritted teeth
With the pointed edge of his claw, Sukuna draws a line down the boy’s stomach and creates a circle above his pant line. “I have a proposition for you, little one.”
With his breath caught in his throat, Satoru whispers, "What is the proposition?" The drag of Sukuna's nail on his skin lightly stings, but it's the pain that it's leading up to that scares him. He doesn't know how Sukuna plans on hurting him this time.
“You wish to become strong, right? Strong enough to defeat me.” Sukuna first answers with a question. His longer fingers slide under the boy’s waistband, tracing the delicate skin of his hip bone.
"I am strong," Satoru frowns. He still confident in his abilities because aside from Sukuna, there has been no one who could best him. But Sukunna is different, and the difference between him and the rest is nearly as insurmountable as the distance between the earth and the heavens.
“You are.” Sukuna confirms as his hand slides further down the boy’s shorts to palm over his small cocklet. “But I could mold you into a formidable oni.”
“How w-would you be molding me?” Satoru’s breath hitches in the middle of his sentence when Sukuna’s hand brushes against his crotch. Even if he’s not sure if the movement was intentional, it makes Satoru feel funny.
“I would train you.” Sukuna wraps his hand around the boy’s cocklet and begins to lightly stroke. He’s so small in his hands, completely engulfed within Sukuna’s large fist. “I won’t go easy on you, but you’ve already shown me you can endure pain. You may even grow to like it….”
Satoru whimpers and squirms as Sukuna’s hand envelops his penis, at how it makes his stomach feel weird the same way Sukuna had done when he played with his nipples. It’s ticklish, and Satoru has always hated being tickled, but for some reason he doesn’t want Sukuna to stop.
“Sukuna… what are you—” Satoru lets out an embarrassing moan.
“Have you ever touched yourself like this before?”
Sukuna asks with a low voice as he drinks in the boy’s flushed expression and useless squirming. His eyes droop when the boy moans. It’s so cute and Sukuna wants to draw more from him. The pace of his fist increases as he massages the boy’s prick more deliberately.
“No, it’s dirty…” Satoru says quietly between sharp breaths. He doesn’t touch himself there because that’s where pee comes out of, but then he remembers that he had put his mouth on Sukuna’s penis and he wrinkles his nose.
Sukuna chuckles at the comment, “Are you calling me dirty?”
As one hand strokes on the boy’s hardening cocklet, Sukuna slides the other up Satoru’s torso, tickling him with the edge of his claws until he’s back on his nipple, rubbing the sides of it with two spread fingers. “Something as pure as you could never be dirty.”
Satoru isn’t entirely sure what Sukuna means when he calls him pure, but it sounds like a compliment and it makes his chest warm.
“You’re making me feel weird,” he complains when Sukuna’s fingers return to his nipple. Like something is going to burst inside him.
“It may feel weird the first time, but it also feels good, don’t you agree?” Sukuna doesn’t let up, curling his wrist with each tug of the boy’s prick. His voice is dripping with arousal as he plays with Satoru’s nipples until they’re hard again between his fingers. “This is only a fraction of what you’ve done for me.”
Satoru’s knees squeeze together, overwhelmed by all the new sensations. It does feel good, but he’s also so sensitive, and it’s too much for him all at once. His eyes are wet as he tries to squirm away from Sukuna’s hands.
“Sukuna, I— I’m going to…” Satoru shudders, unable to describe what he’s feeling, except that it kind of feels like he needs to pee. He doesn’t want to pee in front of Sukuna. He’s not a child who still doesn’t know how to hold in his pee, but if Sukuna keeps doing what he’s doing, he won’t be able to stop himself.
“Going to what, hm?” Sukuna mocks as he presses more weight down onto Satoru, pinning him down as his hand thrusts on his throbbing cocklet. “Don’t be shy, I want to hear you.”
“You’re going to make me pee,” Satoru whines, embarrassed by the admission. But that means Sukuna will probably stop, right? He can’t imagine that Sukuna wants to be pissed on.
Sukuna lets out a breathy laugh and pinches the boy’s nipple, hard. “Then pee, make a mess of yourself. Don’t hold back.”
“No…” Satoru mewls, but it’s too late to stop. His stomach cramps up and he gasps as it feels like he’s releasing his bladder, but nothing comes out. He cries from the intensity of the sensation.
Sukuna’s eyes widen and he watches with unblinking eyes. There’s nothing on his hand, the boy is simply too young to produce seminal fluids, but it’s undeniable that he just experienced his first orgasm.
“Good boy. How did that feel?”
“I don’t know,” Satoru mumbles, dazed. He’s overstimulated, sore, and suddenly heavy with fatigue. Even though nothing came out of his penis, he’s as humiliated as he would’ve been if he had wetted himself in Sukuna’s hand.
“You did so well for me. There’s many things I will teach you.” Sukuna releases the boy’s prick and nipples and hovers his hand over Satoru’s belly, where his womb would be. “There’s only one thing you will do for me in exchange.”
Without warning, small but precise flames shoot from Sukuna’s fingertips to sear the boy’s flesh, burning an image like a brand onto his skin.
“Stay with me and be mine.”
Satoru softly moans from pain as he’s branded, but the pain of fire licking his flesh is at least something he’s familiar with for once. His sight is too blurred to see the pattern Sukuna is drawing on his skin, but he doesn’t intend to let it stay there once he’s able to heal again.
“What do you mean be yours?” Satoru’s voice is small and strained, but he’s dizzy from the praise Sukuna gave him. That he did so well for him.
“Perfect boy,” Sukuna coos, pleased by his soft moans. “You will be my pupil, and my concubine.”
Sukuna begins to chant in a deep voice as sharp lines of a curse mark burn onto Satoru’s womb, matching the tattoo on the oni king’s forehead.
“Your pupil…” Satoru mouths, entranced. Sukuna has never taken a pupil to his knowledge, and the privilege of being the first, of being *special,* is hard to resist. He doesn’t know what to do with all the praise Sukuna is giving him, but he covets it. Sukuna is far from the first individual to recognize him, but only his recognition holds any weight.
“Yes. You’ll grow stronger than you could ever imagine, and by my side, many will cower at the very mention of your name.” The boy’s pale skin sizzles around the wound, image almost complete as it’s seared into flesh. “Is this your wish?”
Sukuna needs the boy’s agreement to solidify the binding vow, the one that will curse him and make him akin to property.
Satoru is feeling faint, but he can’t think of any reason to refuse the offer. He challenged Sukuna to be recognized, after all, and he can always kill Sukuna once he’s been given the tools to surpass him.
He nods, not knowing that he’s sealed his fate into a far unkinder future than what he has in mind.
Sukuna grins, and the brand turns from orange to black, like a permanent tattoo over the boy’s womb. Sukuna cups his small face in his hand and leans in close, “Now you’re mine.” Then he presses their lips together, sealing the deal.
It’s Satoru’s first real kiss, an innocent peck on the lips to start with. He purses his lips together because that’s how he thinks kisses go.
Sukuna hums into the kiss, “Open for me.” He wants to taste what’s his.
Satoru obediently parts his lips, curious as to what Sukuna will do.
Sukuna slides his long tongue into the boy’s mouth, pressing against his velvet tongue to taste him. He’s so sweet, and pliant after his first orgasm that Sukuna is already looking forward to more. The boy is strong, able to take him even on his first time, so he wonders how far can be pushed until he breaks.
Satoru moans from the feeling of Sukuna's tongue snaking inside his mouth. He hadn't known that his mouth is so sensitive as well, like Sukuna knows his body better than he does. His lips part even further in a silent plea for more.
Sukuna moves languidly, taking a moment to enjoy the kiss and how the boy opens for him without restraint. When he releases, a trail of spit connects their lips.
“Let’s get you off the floor, it’s no place for the king’s concubine.”
Chapter Text
Sukuna stands and reaches down to pick up the boy and cradle him in his arms.
“Concubine?” Satoru asks innocently. It’s the second time Sukuna has used that word.
His lips are wet and tingly as Sukuna carries him. He quite likes being kissed, Satoru finds. Satoru hopes that Sukuna is taking him to bed because he’s tired and ready to sleep.
“Yes. You will live here and serve me as one of my mates. Don’t worry, you’ll be treated nicely in the shrine and recognized as mine by the servants and others.”
Sukuna carries the boy to his bedroom and tosses him onto a large king bed adorned with red silk sheets. He climbs on top of him, leaning in to kiss Satoru once more.
Satoru is glad that he's been taken to a bed as he'd hoped. His small body seems to sink into the sheets, and the weight of his fatigue settles into his bones. He likes when Sukuna kisses him, so he eagerly parts his lips without being told to allow Sukuna's tongue inside his mouth.
As they kiss, Sukuna begins undressing the boy completely, finally sliding off his pants to expose him. His hands wander freely down the boy’s slides, gripping and squeezing possessively.
Satoru doesn’t mind when Sukuna undresses him; he’s too young to know to feel any shame about nudity, and he likes sleeping without clothes on. It’s only when Sukuna’s hands start roaming his body that he feels like something is off.
Sukuna sits up and admires the boy’s body beneath him. He traces the scars left from dismantle with a sense of pride, imagining how he might decorate the boy’s body more. “You wear these scars well, your resilience is impressive.” Sukuna begins to undress, sliding off his kimono to expose his tattooed chest. “I’m sure you can endure much more.”
Satoru stares at Sukuna’s tattoos with wonder in his eyes. He’s never seen them before, and he lifts a hand to trace over one of the lines curiously.
“I can endure anything,” he declares with his chest puffed out. Especially now that he knows how to heal his injuries.
Sukuna lets the boy touch him for a moment, enjoying the sight of his small hand against his chest.
“You can, and you will.”
Sukuna leans forward to lick down the boy’s body with the tongue on his stomach. “I intend to take my time with you today.”
Satoru frowns, squirming a little because of the tongue tickling his stomach. He would tell Sukuna that he doesn’t like being tickled, but somehow he knows that that wouldn’t stop him.
“What do you mean take your time?” It sounds tiring, and he wants to sleep now.
Sukuna demonstrates by sliding his mouth between the boy’s thighs and swiping his cocklet with the flat of his large tongue. “I want you to enjoy it when you take my cock this time.” At least for tonight, he doesn’t say.
Satoru makes a soft sound as his penis is touched. He almost wants to cover himself there with his hands just because of how sensitive it is.
“Take your cock? What is that?” Sukuna has used that word before, but Satoru still doesn’t know what he means by it.
Sukuna can’t help but chuckle. How wonderfully naive. He fully undresses and rests his cocks heavily on the boy’s thighs. “Don’t tell me you’ve already forgotten the feeling of me inside you.”
It takes Satoru a second, but he finally understands Sukuna, and he tries to back away when he does.
“N-no… Not again,” he whimpers. Pain he can tolerate, but not when it’s like that.
Sukuna’s eyes narrow. His voice is low, threatening. “You dare deny me?”
“Why should I obey you?” Satoru bites back. He doesn’t see why he should do everything Sukuna tells him to.
Right as the boy’s words leave his lips, the brand on his womb begins to burn, spreading like black ink down his thighs and up his chest. It’s as if he’s being burned under his skin.
“Ngh…!” Satoru grunts, his muscles seized up as the burning pain seeps through his flesh. It’s not the worst hurt he’s experienced, but he can’t move any part of his body as the ink spreads.
Sukuna watches with a cold expression as the boy’s body is wracked with pain. “I told you, you belong to me.”
“I thought you meant as a student,” Satoru says with an indignant sniffle. He’s realizing now his folly in his agreement with Sukuna, but maybe there’s still a way out of it for him?
“You ought to listen more carefully before agreeing to something.” Sukuna laughs as he grabs Satoru’s legs to press his knees against his chest. “It makes no difference to me either way. The deal has been set, and cannot be revoked.”
“It wasn’t fair!” Satoru says, sticking his tongue out. “You asked me when I was feeling weird!”
He kicks his legs, trying to free them from Sukuna’s hands. While he’s not shy about his body, he doesn’t really want Sukuna to keep looking at him down there.
“Seems you still haven’t learned your lesson after all.” Sukuna leans his weight against the boy’s shins, folding him in half and exposing his little hole. He prods between his cheeks with the heads of his cocks, applying pressure to the boy’s tight rim. Even he is unsure if he’ll fit without breaking the boy completely. “I will simply take what’s mine, then, whether you live or die.”
“But I thought…” Satoru’s voice is small, lacking any of his usual confidence. “I thought you said you wanted me to enjoy it?”
It’s a last ditch effort to save himself without having to beg.
“That all depends on you.” Sukuna stays where he is, but doesn’t press forward. “Will you submit, and obey me as your king?”
Satoru’s pride bristles at the suggestion, and he presses his lips together unhappily. Even just having Sukuna’s… cock poke at him is uncomfortable, and that’s enough to help Satoru make his decision.
“I’ll obey my king.” He says the title with as much sincerity as he can muster, but if he could he would’ve crossed his fingers behind his back.
“Good.” Sukuna coos and pulls back. He cups a hand along the boy’s face in a pseudo-loving gesture. “You haven’t told me your name.”
Huh. Satoru realizes that he hasn’t told Sukuna his name yet. He’s been too focused on trying to kill him to exchange any pleasantries.
“It’s Satoru,” he says. He leans into Sukuna’s touch just a little.
“Satoru.” Sukuna says his name like he’s tasting it, chewing on each syllable. “You will do right by me, and in return, I will train you. It’s a high honor I’ve bestowed upon you, don’t make me regret it.”
“When will you start training me?” Satoru perks up at the mention of being trained, momentarily forgetting the peril he’s in.
“Later, after we consummate our union.” Sukuna purrs as his tongue swipes between the boy’s cheeks. He wraps around his cocklet, consuming him in one swirl of his large tongue.
Sukuna uses a lot of words that Satoru’s never heard of, but he can understand the gist of his meaning now. He whimpers quietly at the still unfamiliar feeling between his legs, but if this is what he has to endure for what he wants, he can do it.
Sukuna’s tongue circles Satoru’s rim and he presses the tip in slowly. At the same time, he wraps a fist around the boy’s prick and begins lightly jerking him to distract from the intrusion.
Satoru shudders underneath Sukuna. The tongue pushing inside him feels strange, but at least he isn’t in pain. Meanwhile, the hand around around his penis feels kind of good in a way that makes his stomach flutter. He moves his hips into Sukuna’s fist, which also lets him be further away from the tongue.
Sukuna takes his time to stretch the boy, moving his tongue slowly as he strokes. “Much better, Satoru.” He praises as he tongue worms inside, seeking the boy’s prostate. He wants Satoru to know that if he’s obedient, he will be rewarded.
Satoru keeps gasping every time Sukuna does something that makes him feel weird. His head is fuzzy and his penis is throbbing in Sukuna’s large hand.
The tongue inside him touches something, and all of a sudden Satoru feels like he’s going to pee again. Like something is waiting to burst out of him.
“S-Sukuna!” he cries out, grabbing at Sukuna’s nearest arm.
Sukuna grins. “Found it.” His tongue begins licking the boy’s prostate in rhythmic laps, coaxing him to open and melt underneath him.
“W-what is that?” Satoru asks between breathy moans. He’s practically melting into the sheets in pleasure.
“This is what happens when you’re good for me.” Sukuna only partially explains. It’s cute how naive the boy is, only knowing what Sukuna tells him, and only knowing his touch.
He flattens his tongue, stretching the boy more as his walls relax around him, hitting his prostate with every flick.
Maybe being good for Sukuna isn't so bad, Satoru decides. He still doesn't like that he got tricked into becoming the oni king's belonging, but he can tolerate this.
"Sukuna..." he whines, his thighs shaking in pleasure. "You're going to make me pee again." His face flushes because he knows that what Sukuna is doing to him won't make him wet himself, but he doesn't know what the right word for it is, and that embarrasses him.
Sukuna chuckles, “Aren’t you too old to pee in the king’s bed, hm?” He almost hopes the boy does, since he’s too young to ejaculate. Sukuna wants him soiled, squirming with embarrassment.
The pace of his hand quickens on Satoru’s throbbing cocklet as he stares down at his flushing face.
“You must be about to cum. Go ahead, let me hear how much you like it.”
"C-cum?" Satoru stutters over the new word. The shape of it is strange in his mouth.
"Sukuna, it's too much," he protests, trying to squirm away from Sukuna's hand and tongue. "I'm going to... gonna—" Satoru squeezes his eyes shut, a few small tears of overstimulation trickling down his face as he orgasms for the second time ever. Just as before, it's completely dry.
“Beautiful boy, did that feel good?” Sukuna asks as he releases his hand in favor of stroking himself. He’s already painfully hard from watching the boy writhe in pleasure beneath him.
"It felt..." Satoru sniffles, still overwhelmed. He's glad that Sukuna let go of his penis, because it was starting to hurt from being touched. He thinks it did feel good, but not a type of good that he's ever known before Sukuna.
“Hm?” Sukuna asks with a playful lilt in his voice. His tongue is still inside the boy, keeping his hole open and wet. “Use your words.”
"It felt good," Satoru says bashfully. Sukuna's tongue feels so strange inside him now that he doesn't have the hand on his dick to distract him, and he clenches a little around it.
“There you go.” Sukuna hums. He releases his tongue and worms his finger into Satoru’s hole to test the wetness and stretch inside the boy. “I’m sure you’ll like this even more.” He presses Satoru’s knees closer to his chest and lines the head of his cock before his entrance. “Take a deep breath.”
“Wait! Sukuna, I’m not sure…” Satoru eyes Sukuna’s cocks warily, remembering how much it hurt when Sukuna forced one inside him last time. He didn’t want the spines inside him either, and he shudders thinking of how they’d drag against his insides.
Sukuna clicks his tongue. “I’ve waited long enough, you should be grateful I stretched you beforehand.”
The oni king doesn’t wait, and instead begins to push his cock past the rim. The boy’s clenching is causing resistance, so Sukuna bullies past until he catches inside the warmth of his small walls.
He moans once the tip is inside,
“You were born to take me”
Satoru gasps at the weirdness of being stretched open down there, but he's relieved to find that it doesn't hurt this time nearly as much. Nor does he feel the pain of the barbs while Sukuna is pushing inside him.
"I was born to take you down, you mean," Satoru says defiantly, but it's hard to keep his composure while Sukuna is inside him.
Sukuna is hardly listening, too lost in the tightness of the boy’s walls as they clench around him. He takes a moment to feel him relax before he’s pushing deeper inside. “I’d like to see you try…” he murmurs playfully as he fills the child with his cock.
The more Sukuna sinks inside him, the more uncomfortable Satoru feels from the fullness until it starts to hurt more than he can bear.
"Stop, stop!" he cries out, reaching his limit. His mouth goes dry when he sees that Sukuna is still barely inside him, that there's still so much more of his cock to fit.
Sukuna thrusts his hips harshly so that he’s filled to the hilt inside the boy. He looks down at him as he leans on his shins, folding him in half to stuff his cock even deeper. “You’re not the one who gives me orders, kid. You take what I give you.” Then he pulls back, scraping Satoru’s walls with the barbs lining his cock.
Satoru screams at the abrupt intrusion, pain flaring up his spine. Already teetering on the edge of overstimulation, the added pain pushes him over, and he whimpers as a pressure building up inside finally freeing from his penis.
It takes him a while to realize that he’s wet himself, for real this time. Satoru is mortified, but the harder he tries to stop the spill, the more his bladder releases from his soft penis. His thighs are soaking wet, and the sheer embarrassment is almost enough to make him forget how much Sukuna’s cock hurts inside him.
Sukuna notices the stench first, stinging in his nostrils then the wet feeling of piss as it drips onto his knees. He laughs, mockingly, “finally something came out of that tiny cock of yours.”
It only riles him further, and he starts thrusting into the boy slowly, carving out his insides to accommodate his massive, throbbing cock.
His thighs and stomach are wet with pee, and Satoru cries as it does nothing to deter Sukuna from thrusting his cock in and out of him. His tears become snotty as he thinks about how he’d wet the bed, something he hasn’t done since he was a little child. The drag of Sukuna’s dick inside him makes him feel bloated, and each inward thrust seems to press against his bladder, squeezing out a few more pathetic drops from his penis.
The boy’s tears are like a melody to Sukuna as he sobs underneath him. He aims for his prostate with each violent thrust, hoping to lace pleasure with the pain.
“You got yourself so dirty, let me help.” Sukuna wraps a hand around his piss soaked cocklet and licks it clean with the mouth on his palm. Even the boy’s piss is delectable, truly a sweet boy in every way.
As Sukuna’s thrusts become more violent, his barbs scrape against Satoru’s walls, scratching him up inside. It hurts so much that Satoru’s eyes are rolling into his skull, but occasionally there’s a spark of intense pleasure that makes him shudder.
Before he knows it, his tiny prick is getting hard again, throbbing painfully against his wet stomach.
Sukuna can feel the boy harden in his fist and he grins. He wraps the smaller tongue on his palm around him, stroking gently. “You’re taking me so well. You’re the strongest boy I’ve had, all the others have died trying to take me.” His voice is hoarse, and breathy as he carves into the tight, warm hole beneath him. He looks down at the little oni as he speaks, “You should feel honored, Satoru.”
Satoru’s hips buck as the wet tongue wraps around his prick. He doesn’t like how pain and pleasure are mixing together, confusing him. He doesn’t feel particularly honored, more degraded if anything, especially after being forced into peeing himself. Sniffling, Satoru throws an arm over his face to hide from Sukuna.
Sukuna grabs Satoru’s arm and stares at him intensely, “Don’t ignore me when I speak to you. Isn’t there something you should say to me, or did you never learn manners?”
Satoru is in too much pain to speak properly, so he just gurgles hatefully. He shakes his head, trying to express his unhappiness. He knows he's bleeding from the barbs raking against his walls, but he's too scared to look.
“You really want to be like this?” Sukuna growls low in his chest. He thrusts his hips punishingly, dragging the barbs out so forcefully that a pool of blood seeps from the boy’s abused hole. “You know I have the ability to make this hurt less for you, but you have to earn it.”
Satoru moans in pain from the abuse, trying to close his legs so that the blood will stop spilling out. So Sukuna can stop staring at his torn hole. His eyes are puffy with tears, and he keeps shaking his head while sobbing, only partially registering Sukuna's words.
Sukuna exhales in frustration. “I’m disappointed.” But he’s placing his palm over the boy’s hole to send a warm wave of healing energy against his tattered rim. It repairs the damaged skin within his reach, and should feel soothing. “This is the only time I will do this without asking.”
A small gesture of mercy is no use to Satoru when Sukuna is the one injuring him so severely. Satoru glares petulantly at Sukuna through his wet lashes, upset about being taken advantage of by their unfair contract. He feels gross, his body slick with blood, sweat, and urine. He hopes some of it gets on Sukuna so he's also left feeling gross and sticky.
Furious, Sukuna begins pounding into Satoru violently, seeking his release selfishly with no regard to the way his walls are being shred apart by the barbs. The blood makes the glide easier, squelching lewdly as he slams into the boy.
Sukuna's switch into greater cruelty doesn't surprise Satoru at all, but he's still unprepared for how much more it can hurt. It's worse than the first time Sukuna did this to him; at least then, he had numerous other nearly fatal injuries on his body distracting him. It feels wrong to be bleeding from the inside like this.
A few more fast and furious pumps and Sukuna is collapsing onto Satoru’s knees, practically crushing him with his weight as he cums with a growl. The hot semen filling his bloodied hole must sting as Sukuna lingers for a moment in the mess he created.
Satoru is still glaring at Sukuna when he finishes inside of him. The warmth filling his tattered insides burns as it washes over all his cuts and scrapes. He doesn't know what Sukuna spilled inside him— it's too viscous to be urine. Either way, it leaves him feeling disgusting and used.
Sukuna unceremoniously pulls out from Satoru, spilling blood and cum all over the sheets. “I see that wasn’t enough to wipe that insolent glare off your face. I wonder if you’ll still hold your head this high when you finally take both of my cocks.”
"I'll kill you before that happens," Satoru hisses, but he can only feel so strong after being violated so brutally. He turns to his side and pulls some of the bedding over himself, wanting to shield his body from Sukuna.
Without comment, Sukuna stands from the soiled bed and wraps a black haori over his naked body. He rings a bell hung by a rope, which echoes loudly. Almost instantly, a short, white haired human rushes to the room.
“How may I assist, my lord?” They ask with their head held low. Their attire is nicer than that of Sukuna’s other servants, with fine earrings and rings adorning their fingers.
“Escort this brat to his room, and wash my bedding.”
Sukuna orders as he leaves the room without sparing another glance at Satoru.
Uraume carries the boy to his personal bathroom attached to his bedroom. It’s mostly wooden with a large, barrel shaped bath in the corner. They set Satoru down gently and begin running the water.
Their red eyes scan the boy’s body curiously, lingering on the scars and fresh cuts decorating his small frame. It’s unusual for Sukuna to take on a new concubine so quickly, and they’re curious about the boy despite themselves.
“You must be Satoru. I’m Uraume, our lord’s first and oldest concubine.”
Satoru is too sullen to pay much attention to them, and humans are beneath his notice anyway. He gives Uraume a brief nod then looks away, disinterested.
The water running over his body in makes his wounds sting, and the it quickly turns pink from blood. He sits with his legs drawn in, his cheek resting on his knees. He’s shaky, still a little afraid, and very much enraged.
Uraume lathers a sponge with soap and begins cleaning the boy gently, being mindful of his various wounds. They notice the blood, but don’t comment on it. “It’s a great honor to be a concubine of the king, I hope you will settle into your new life with ease.” They say proudly as they spread soap along Satoru’s shoulders.
“Do you really believe that?” Satoru mumbles moodily, cheek still pressed against his knee. He doesn’t move from his curled up position, making it harder for Uraume to wash him. He can’t see what honor there is in being used by Sukuna, who he respects less with each time he encounters him.
“Yes, whole heartedly.” Uraume answers without hesitation. “Serving the king is the honor of my life, and I am indebted to him.” They stare at the boy even more curiously, perplexed at how he doesn’t seem happy to be in such a luxurious tub, without even having to work. They push his legs open somewhat forcefully to lather his groin. “You should make sure to do right by him. I don’t know what you did wrong, but our lord didn’t seem pleased earlier.”
Satoru bristles at having his legs forced apart, by a human nonetheless. Still, they’re washing him so he allows it to happen.
“Don’t touch me like that without asking, human,” Satoru hisses. It’s the most he’s said to Uraume so far. “And I don’t know why you think your king is so great.” He says the title like it’s an insult. “How great can Sukuna be anyway? He just let a little boy pee on him.”
Uraume’s eyes widen at the audacious words spoken by the boy. “How dare you speak ill of him.” They say sternly. “Who do you think you are?”
“Who does he think he is,” Satoru scowls. “I don’t see why I should respect the king of piss.” The fact that Sukuna had completely overwhelmed him twice now in battle does nothing to change Satoru’s low opinion of him.
Uraume drops the sponge into the water and slaps Satoru across the face, harshly. “If you weren’t our lord’s concubine I’d kill you on the spot for your insolence.”
Satoru snarls at Uraume. Though the hit from the human hardly felt like anything, he’s furious.
“Touch me again and I’ll eat you, human.” Satoru bares his fangs, and a tinge of blue spreads across his skin from his anger, his control over his shape shifting slipping.
Uraume considers screaming for help, but wants to stand their ground. They’re the king’s favorite, after all.
“It’s not wise of you to threaten me.” They say calmly and sit in the corner of the room, away from the tub.
“You look like you’ll taste bad anyway,” Satoru continues to sulk, splashing the water a little. “I wouldn’t want to eat your chicken feet hands.”
“I can’t fathom what the king sees in a rude and entitled brat like you.” Uraume spits, letting frustration rise to the surface for a moment.
Of all the concubines they’ve seen over the years serving Sukuna, Satoru is by far the worst behaved. It’s hard to understand why he’d grant such a privilege to someone who lacks even basic respect.
Satoru sticks his tongue out at Uraume, not feeling like speaking to the human anymore. As he scrubs the parts of his body that Uraume couldn’t reach, his stomach starts to growl. He hasn’t eaten in days, and his hunger is finally catching up to him.
“I’m hungry.” He looks expectantly at Uraume, acting as though he hadn’t just gravely insulted them.
“That so?” Uraume asks with a flat tone and inspects their nails beds curiously.
Satoru blinks, then frowns at how his request for food was blatantly ignored.
“Staring at your hands won’t make them look any less like chicken feet.” He kicks his feet in the tub to make water splash out just because he’s feeling petty.
Uraume rolls their eyes. “Finish your bath so I can dress you and escort you to the hall for dinner.”
Satoru is mostly done anyway, and reinvigorated by the thought of food. When he tries to stand from the tub, however, he wobbles and collapses from the terrible soreness between his legs.
“I don’t think I can walk,” he says quietly, ashamed of his weakness.
Uraume scoffs outright at the pathetic state of the boy. “Are you asking for my help?”
"I guess I'll just sit here until I prune and wither away," Satoru sighs dramatically. "I'm sure Sukuna will be happy to hear what happened while he was away." He's not actually entirely sure if Sukuna would care, but Satoru knows that he would be upset if something that belonged to him got broken by someone else.
Uraume’s eyes narrow for a moment but then their face settles back into a neutral expression. “No, the king requested your presence at dinner and I will see to it that his wish is granted.”
They grab a towel for Satoru and hand it to the boy. “Lean on me if you must.”
Satoru stumbles as he tries a second time to get up, but this time he's able to stabilize himself on Uraume. He wraps himself with the towel to dry himself off, liking how soft it feels against his bare skin.
"Does that mean I'll have to eat with Sukuna?" He doesn't really want to see Sukuna's face again any time soon.
“Yes, of course. You will meet the other concubine as well.”
Uraume leads Satoru to his room. It’s different from the one he stayed in prior; larger, more elaborate. The room is filled with fine art and furniture, with a luxurious futon in the center.
On top of the futon is a light blue kimono.
Uraume nods to it proudly, “A gift.”
Satoru picks up the kimono curiously. It's the exact right size for him, which must mean Sukuna had previously not only taken his measurement, but also had it tailor made for him. He's uncomfortable thinking about how much Sukuna must have planned for all of this, tricking Satoru into being his possession.
"I don't like it," he complains as he puts it on. It restricts his movement around the legs so much more than what he usually wears. He almost just wants to go naked instead, but then he remembers he doesn't like the way Sukuna looks at his body.
“You will wear it with pride.” Uraume says as they assist in tying the obi belt around Satoru’s small waist. The kimono really suits the boy, highlighting his slender figure and delicate wrists. The light blue silk matches the color of his sparkling eyes, and makes his hair appear bright as snow.
Uraume leads Satoru to a vanity and sits him before a mirror. Gingerly, they begin brushing his hair.
“Sukuna seems to have taken a special liking to you, do you understand the privilege you have?”
"Do I have to do all this to eat?" Satoru complains, feeling antsy and confined. As he sits down, Satoru winces, shifting around and finding that there's no way for him to sit without being uncomfortable and in pain. If he could, he'd just walk out of the room and follow the scent of food until he reaches the dining hall, but he can't walk without Uraume's help, so he's left hostage to their design.
“You will dress appropriately for dinner with the king.” Uraume sighs and places a hair clip into Satoru’s hair a bit too roughly. They spin Satoru around in his chair so that he’s facing them. “Purse your lips together.”
Being spun around made the throbbing between Satoru's legs hurt even more, and he bites back an unhappy moan. Glaring at Uraume, he purses his lips together. He doesn't like how this human treats him, but he can't do anything about it at the moment.
Uraume applies a pink lipstick to the boy’s lips. “Now rub your lips together, like this.” They mimic the motion for Satoru to follow.
"This is stupid," Satoru mutters as he copies Uraume. They're just wasting time, and Satoru is getting hungrier by the minute. His stomach growls again, louder than before.
Uraume has to force themselves to be gentle when applying a soft blush to the boy’s pale skin. They want nothing more than to rip his cheeks and stuff his face with the makeup brush until he gags on the powder. It’s hard to be patient around him, fighting at every turn despite the glamor and riches being handed to Satoru on a silver platter.
Once finished, they spin Satoru around to look in the mirror. He looks like a doll, refined and elegant.
“You’re almost lovely, when you don’t speak.”
Satoru hasn't seen too many reflections of himself, but he thinks he looks silly. He's never seen anyone with their face painted like this, and he pokes at his cheek, smearing some of the powder on his fingertip.
"I look stupid right now," he complains. "Why did you make me look like you?"
“It’s for the king, now come.” Uraume offers their arm for Satoru to help him from the chair. “We mustn't be late for dinner.”
Satoru brightens at the mention of dinner. He hopes there's a lot of meat, maybe even something fresh and still alive. That'd be nice. Grimacing as he rises from his seat, Satoru takes Uraume's arm. He should be able to heal himself by tomorrow, so he won't be needing Uraume anymore after.
They walk slowly through a long hallway towards an immaculate dining room. It’s well lit with candles and lanterns, with a long wooden table in the center, already set with plates.
The head of the table is empty, indicating Sukuna has not yet arrived. There are, however, two others already sitting, and they stare at Satoru curiously.
“Please, sit.” Uraume nods towards the zabuton on the tatami. Satoru’s place is second from the head, on the left, next to a brown haired woman.
Satoru unhappily sits where he was pointed to, and scowls when he struggles to sit down because of his soreness. He can feel the strangers’ eyes on him. While he usually doesn’t mind being stared at, he doesn’t like that they’re seeing him dressed stupid and struggling to sit.
“When am I going to be able to eat?” he mumbles. There’s no food on the table, and he hadn’t known there is going to be so many other people eating with him. He thought it’d be just him and Sukuna, and he doesn’t know why he’s a little disappointed to find out that’s not the case.
“Everyone, this is Satoru.” Uraume introduces him unenthusiastically as they take their seat. “Please excuse his rudeness, the boy seems to lack even basic manners.”
The blue haired concubine snickers and gives Satoru a blatant up and down with his eyes. “So you’re Sukuna’s new concubine, I’m surprised at how small you are.”
The brown haired woman scoffs and turns to Satoru.
“It’s nice to meet you, I’m Yoruzu.” She smiles down at him warmly. “Kashimo is right though, how old are you…?”
Satoru glares defensively at the blue haired one, disliking how he’s eyeing him up similarly to how Sukuna does. It’s worse coming from someone who isn’t Sukuna, and has even less of a right to look at him that way.
“I’m almost ten!” Satoru declares, his chest puffed up. He doesn’t know his exact age, but he does know his birthday is supposed to be some time in the winter. He’s more than halfway to being an adult, so he expects to be treated with some respect.
The three concubines are silent for a few moments, shocked into disbelief. Although Sukuna has been known to have explicit and perverse sexual interests, he’s never taken a concubine so young. It's hard to imagine how Satoru could survive, both in battle and in the bedroom with the oni king.
Yorozu swallows audibly, a hint of bitterness in her voice, “I see….”
Kashimo chuckles with interest, “I’ve heard you were strong, but what can a nine year old even do?”
"I can still beat you up," Satoru scowls. He really doesn't like the blue-haired one, who not only looked at him wrong, but is now also insulting his abilities. He's certainly no Sukuna, and therefore he has to be weaker than Satoru. If only Satoru weren't completely drained of strength, or he'd show Kashimo his proper place. "And I said I'm almost ten."
“Oh yeah? You’re on.” Kashimo grins wickedly. As he begins to stand up, his eyes widen at the sight of Sukuna staring down at him. He immediately backs off, sitting upright on his cushion.
“I trust you’re all getting along.” The oni king states as he takes his seat at the head of the table. His red eyes fall directly onto Satoru, a hint of fondness behind them. The fine clothes suit the boy well, more beautiful than a geisha.
Satoru slouches as he sits with lingering displeasure and uncomfortable soreness. But he snickers quietly to himself how quickly Kashimo became subdued the moment Sukuna walked in, without the oni king having to say a single word.
Satoru never thought he’d want to see Sukuna again after what he had done to him, but somehow the dreaded king of curses is preferable company. Still, he pretends not to notice Sukuna, upset about how he was treated.
The servants fill everyone’s cups with the finest sake, including Satoru’s.
Sukuna holds his cup high for a toast,
“To divine pleasures and pursuit of strength.”
He sips his sake slowly and relaxes onto his seat with his legs crossed.
Divine pleasures… Satoru has never been a pleasure chaser, but he thinks of the strange new feelings Sukuna has introduced to him and his face goes warm.
Satoru doesn’t toast with everyone else, but he does lift his cup for a curious sip. He pulls a face at the taste and the way it burns, but he’s also thirsty enough that he gulps it all down quickly.
The servants rush in with several bowls and plates full of food to prepare the Kaiseki. First, there’s rice and soup. Various smaller plates of lotus root, steamed vegetables and sashimi are also placed liberally along the table.
“Itadakimasu” Uraume begins, and the other concubines follow. They look at Satoru expectantly.
Satoru doesn’t notice their gaze, too busy staring at the sashimi. He doesn’t bother to give any of the steamed vegetables a look either. He’d prefer something tougher and bloodier than fish, but at this point Satoru will take any kind of meat.
He’s the first to reach for any of his dishes with his chopsticks, before Sukuna even.
Sukuna glares at Satoru.
“Take his chopsticks away until he’s learned basic respect.”
He then turns his gaze away and begins eating, starting with the soup.
With a bow, a nameless servant clad in all white snatches the chopsticks from the boy.
Satoru glowers at Sukuna, his stomach grumbling. He doesn’t know what he had done wrong, but if he must eat with his hands, he will. This time, he picks up a slice of sashimi and manages to stuff it in his mouth before he can be stopped. It’s the first thing he’s had to eat in too long.
Uraume gasps in shock at the sight of the boy eating with his hands.
“How unsightly, you’re not some animal!”
Sukuna nods towards the servant, who swiftly removes the bowl from Satoru’s reach.
“You’ll eat properly, or you’ll eat nothing at all. What is your decision?”
Satoru doesn’t like how he’s being scolded. “What do you mean, eat properly? And how should I do that if you take my chopsticks away?”
Uraume begins to stand up and scold Satoru, but is stopped by Sukuna’s large hand.
“Simply say “Itadakimasu”, like the rest of us.” He explains calmly, looking at the boy curiously. “It’s a means of showing gratitude for your food and is customary to say before eating.”
All three concubines stare at Sukuna in disbelief. If any of them were to act so rudely, he’d slice their hands off. Why does the child get special treatment?
"Itadakimasu," Satoru says reluctantly, his eyes glued to his lap. His face is red after being disciplined in front of everyone else, and being stared down at everyone for supposedly misbehaving. If he has to do this before every meal, he'd rather run away and fend for himself again.
Sukuna nods towards the servant and the food and chopsticks are placed in front of Satoru once more.
Sukuna is quiet as he eats, savoring every bite. He doesn’t look towards Satoru again.
The glasses are never kept empty, dutifully filled by servants. Several more small plates are brought out as soon as one is emptied in a luxurious feast.
Then the main dish is brought out with an announcement: finely sliced human heart, well seasoned and cooked medium rare.
The servants keep refilling Satoru's cup with the strange liquid, and since he has nothing else offered, he keeps drinking it. His entire body feels warm, and his face especially, like the blood vessels beneath his cheeks are throbbing. At some point, he realizes his vision is blurred. He wonders if he's been ingesting poison this entire time.
At least he's no longer hungry after eating so many slices of sashimi, even if his head hurts and feels like it's been stuffed with cotton.
Throughout dinner, Sukuna glances up at the boy, keenly aware of the flushing on his cheeks and the way he sways in his chair. He must be drunk, how cute.
“Satoru,” Sukuna calls with a low voice, “Come over here.”
It takes Satoru a moment to respond, and he's almost happy that Sukuna is giving him attention before remembering that he's supposed to be mad at him.
"Okay," he mumbles with a confused frown. It's hard for him to stay steady as he walks, and he's pretty sure everyone's eyes are tracking him again.
Everyone’s eyes are tracking him, in shock and a sense of bloodlust. Sukuna pays them no mind, instead watching the boy shuffle in his fine kimono towards him without complaint.
“Sit.” He instructs as he pulls Satoru onto his lap.
Satoru doesn't really want to sit on Sukuna's lap; it doesn't look very comfortable to him compared to the soft zabuton. Sukuna doesn't give him a choice, however, and he's too weak and disoriented to fight Sukuna off. He grimaces, ass throbbing in pain as he's pulled down by Sukuna.
Sukuna hums and settles the boy atop his thigh, wrapping an arm around his thin frame. He fits nicely, like it’s where he belongs. Sukuna looks down at his reddened face and smirks, “Are you enjoying yourself?”
Satoru stares back at Sukuna, his expression somewhat vacant. "Will there be more meat?" he asks. He's craving lamb, cow, or maybe even human. Something from an animal larger than fish.
Sukuna grabs a piece of the thinly sliced heart with his chopsticks and holds it up to Satoru’s mouth. “Open.”
The slice of meat looks different than what Satoru is used to, and smells different as well. Nonetheless, he opens his mouth like a baby bird and waits to be fed.
Gingerly, Sukuna places the meat into the boy’s open mouth.
Satoru takes the offered slice eagerly. It’s chewy, and while it’s not as bloody as the meat Satoru usually has, the flavor is rich and has him wanting more the moment he’s done.
“It’s good,” he says, turning around to look at Sukuna with wide, sparkling eyes. “Why does it taste like that?”
Sukuna is stunned for a moment when Satoru looks at him. He’s never seen such joy on the boy’s face, and he finds himself wanting more, to have him look at him like this again, and again. He squeezes his arm to pull Satoru in closer to his chest.
“It’s human heart, and it’s mostly just salt and pepper.” Sukuna explains as he picks up another slice to feed Satoru. “Have you never had cooked meat before?”
“Why would I?” Satoru asks, except he’s quickly understanding the reason. Cooking his meat had always seemed like more effort than it is worth, but now he sees that it tastes so much better this way, even if it means he’ll have to wait a little longer to eat.
Maybe staying here and having to say and do silly things before eating isn’t so bad if he gets to have Sukuna hand feed him cooked meat.
Uraume, Kashimo and Yorozu are silent as they pretend to focus on their food, wondering how long before Sukuna gets bored of his new plaything. Or how soon before the kid dies.
Usually they compete for the king’s attention, finding ways to stand out and gain his favor. It’s always felt fairly even amongst them, each feeling acknowledged enough by Sukuna to feel satisfied.
Tonight, however, he’s hardly spared any of them a glance, let alone a word.
Sukuna is unbothered by the tension at the dinner table as his attention is engrossed solely on Satoru.
“You must have lived as a feral child before this, which explains why you have such bad manners.”
Sukuna laughs lightly as he sips more sake. His hand runs along Satoru’s back and he continues feeding him. “I have a feeling you’re going to like the dessert, too.”
Satoru doesn't notice Sukuna's hand on his back at first, too preoccupied as he is with the delightful new tastes. He feels he's learned so much about enjoyment since he's met Sukuna, as well as new ways to suffer. While he's still conflicted about how he feels about the oni king, for now he's more than happy to sit on his lap and eat delicious things.
Satoru shivers when he registers that Sukuna is touching his body, little goosebumps prickling across his skin. Though Sukuna has yet to wander beneath his robes to lay his hands on his bare skin, he's a little wary. He's still in pain from what Sukuna had done to him mere moments ago.
Soon after, the servants arrive with dessert: mochi of various flavors.
“Try this.” Sukuna grins as he holds a strawberry mochi between two fingers for Satoru.
Satoru blinks. He's never enjoyed anything that isn't meat, but so far Sukuna hasn't led him astray with the food. Closing his eyes, Satoru takes a bite of the mochi, his eyes flying open the moment its taste hits his tongue.
"It's so good! What is it?" He turns to look at Sukuna again, an expression of awe on his face.
Sukuna smiles down at Satoru’s cute expression. For the moment, he’s forgotten all about his rudeness earlier, both in bed and at the dinner table.
His fingers are lingering near the boy’s lips, and he lightly brushes them. “Strawberry mochi. There’s other flavors too. Do you want to try chocolate or matcha next?”
Satoru nods eagerly, already addicted to the taste of sugar. There's a small line of drool threatening to spill from his lips, and he hastily sucks it back in. Sukuna's cruel actions are entirely forgotten in favor of chasing this delightful new pleasure, and he wiggles happily in the oni king's lap.
Sukuna laughs through his nose and chooses chocolate for the boy. This time, he places the sweet into Satoru’s mouth with two fingers. He can feel the softness of his lips brush against them, and he shudders remembering the feeling around his length.
Satoru accepts the chocolate mochi and Sukuna's fingers without hesitation, his gluttony overriding any sense of rationality he has left in his alcohol-addled mind. The flavor of this one is richer and deeper, yet just as sweet. He even licks the tips of Sukuna's fingers for the powdery sugar residues without realizing that he's doing it.
“Good boy.” Sukuna coos. He licks his own finger to taste the sugar and spit still wet on the tips. His hand then slides forward to wrap around Satoru’s leg, fingers curling towards his inner thigh with a possessive squeeze.
Satoru jumps in his seat from the squeeze, the enchantment cast over him by the desserts shattered. He raises his head and sees the hateful glares of Sukuna's other concubines, his thighs shifting around in discomfort. He's not used to being gawked at so openly by so many people, he's barely accustomed to being around others to begin with.
The praise doesn’t go unnoticed, as jealousy flares up in the room by Sukuna’s blatant display of affection.
Yorozu is pouting as she looks at Sukuna, “Will you be staying with Satoru tonight, my lord?”
Sukuna shakes his head, “No, not tonight. We’ve already consummated our union and the boy needs to rest.”
The woman beams and smiles, “Then perhaps you’d stay with me tonight? I miss you so much, my king. The bed feels so empty without you.”
Sukuna’s hand stays where it is as he grabs the last piece of mochi for himself, swallowing it with a pleased hum. “Come to my room tonight. Be sure to wear that dress I like, and don’t shower.”
At the mention of rest, Satoru's eyes start drooping. He had stayed awake to eat, and now that his belly is full, the lull of sleep calls to him. He curls into Sukuna a little, unable to hold his head up for much longer.
Sukuna notices the boy dozing off and pulls him in closer to rest on his chest. Satoru’s sleeping face is so peaceful, like a little angel in the demon’s lap.
Once dinner has concluded, Sukuna hands Satoru to Uraume to be escorted to his bedroom for the night.
Chapter Text
Satoru doesn’t remember how he got to bed last night, but his heart is racing as he wakes up, kicking the sheets off his futon. He winces as the action makes his behind throb in pain, but it’s easy enough for him to heal his injuries after a decent rest.
Sukuna promised that he will train him, and Satoru intends to keep him to his word. He wanders the halls, a little lost, but he eventually does find Sukuna’s room. Slamming the door open, Satoru announces himself:
“I’m here for you to train me!”
The light filtering into the room is a warm hue of orange, the sun still rising above the horizon.
Yorozu’s head whips sharply behind her to glare at Satoru for his rude intrusion. Her hips still atop Sukuna, hands splayed out on his naked chest.
Red eyes lock onto Satoru as he squeezes Yorozu’s ass possessively.
“We’re busy. Get out.”
"No you're not," Satoru scowls. "You're just laying in bed. And you promised that you would train me. If I have to fulfill my end of the deal, shouldn't you have to as well?"
“Afterwards.”
Sukuna turns his attention away from Satoru and back to the woman on top of him.
“Don’t mind him, keep going.”
Yoruzu chuckles and resumes riding Sukuna. She moans as he fills both of her holes, stretching her further with every bounce of her hips.
Satoru pouts at being dismissed, and he stomps his feet a little.
“What are you busy with anyway? And how long is it going to take?” Satoru whines impatiently. He’s annoyed with how Sukuna got what he wanted from their deal immediately while he’s making Satoru wait.
“It’s going to take longer if you don’t stop complaining.” Sukuna grunts and begins thrusting into Yorozu harshly. She screams in between manic laughter as she’s bobbed over Sukuna like a rag doll.
“Why don’t you come over here and help if you're so impatient?”
Satoru blinks. “Help how?”
He carefully approaches the two of them, their moving forms hidden beneath the covers. A trickle of doubt creeps into his mind.
“Come closer.” Sukuna practically purrs as he looks at Satoru hungrily. Just the sight of him has his arousal blooming more, and he imagines the woman on top of him is the small, smooth boy approaching his bed.
Frowning, Satoru ignores the sense of danger making his skin prickle. He walks up to Sukuna, a slight shiver running down his spine from the look Sukuna is giving him.
“This is your first lesson.” Sukuna says between labored breaths. “Watch and learn.”
He removes the covers, exposing Yorozu’s naked body. Her breasts bounce with each thrust of Sukuna’s hips, glistening with sweat in the early morning light.
Satoru stares dispassionately at their naked forms, disinterested in what he's seeing. "What exactly am I supposed to be learning from this?" He steps a little closer to Sukuna, thinking that there may be something that he's not noticing from being too far.
“Notice how well she takes me, how she rolls her hips…” Sukuna explains, as he guides Yorozu’s body over him. He slows the pace, dragging his cocks in and out of the woman for Satoru to watch.
“Oh, my lord…” The woman moans from the attention, eyes practically rolling back in her skull from the intensity of taking Sukuna.
“I don’t see how that’ll make me stronger…” Satoru’s feeling a little warm watching them now, and he avoids looking at Sukuna’s cocks. But he remembers how it felt when Sukuna touched his penis, and he’s curious if that’s what Sukuna is feeling now.
“It’s not easy to take me, as you well know.” Sukuna comments. “Do you think you’re strong enough to do this like Yorozu?”
“I’m stronger than she is,” Satoru scoffs. She’s just a mere human, after all, even if he’s still smaller than her.
“That so?” Sukuna raises an eyebrow at Satoru. The boy is so desperate to prove himself, he’s unaware how easily he’s manipulated by it. Sukuna reaches for the boy and pulls him in closer by the small of his back. “Do you like watching?”
“No.” Satoru stubbornly looks away from the two of them, though he is a little fascinated with how Sukuna’s cocks are disappearing into the woman’s body. He knew that what women have between their legs is different than what is between his, but he’s never bothered to look closely before.
“Perhaps you’d rather join, then.” Sukuna reaches for the boy’s hand and places it onto Yorozu’s breast.
“Touch her.”
"No thanks." Satoru recoils a little, trying to pull his hand away. He pulls a face at how damp with sweat her skin is.
“You can watch, then.” Sukuna hums as he grips Yorozu’s breast in his large hand, flicking her nipples with the tongue in his palm.
"That's boring." Crossing his arms, Satoru scowls. "Hurry up so you can train me." He almost wants to flee from the room before Sukuna can decide that he wants Satoru to do more than just watch.
“You’re not the one who gives me orders.” Sukuna flicks his hand to give Satoru a warning slash across his chest.
He then turns his attention away from Satoru, in favor of the woman on top of him. She’s wet with slick and blood, dripping down her thighs and onto his stomach. With a grunt, he picks up the pace of his thrusts to seek his pleasure selfishly.
Satoru pulls a face as he heals his wound, then prods at the rip Sukuna had made in his clothing.
"Is this what you do all day? You're kind of boring." He sighs as he inches away from Sukuna, sulking that he isn't getting the kind of attention he wants.
“You’re the one just standing there, gawking like a fish. Seems more boring to me.”
Sukuna mocks with a playful lilt to his voice. His eyes peek at the exposed skin from the boy’s shirt, interest betraying him.
“Only because you’re making me wait.” Satoru glances back at Sukuna and wonders if the woman above him is truly enjoying what he’s doing to her. She acts like she is, but he can’t understand how.
“Oh, how cute...” Yorozu snickers between gasps. “Are you jealous, kid?” She glances at him with a sultry expression.
Satoru sticks his tongue out at her. “Jealous of what? Your tadpole brows?”
Yoruzu’s mouth falls open, “You can’t talk to me this way!”
Sukuna grunts in annoyance and frustration. He was close to orgasm when the boy was near, but now it feels snuffed out by his childish temper tantrum. He shoots Satoru a death glare then nods towards the door. “Go to your room. You will be dealt with later.”
“Fine! I didn’t want to see your stupid faces anymore anyway!” Satoru stomps off, slamming the door shut harder than when he had entered the room. Sukuna keeps deceiving him, and he’s had enough. If Sukuna doesn’t follow through on his promise some time today, he will just have to cut his losses and find a way to get stronger on his own.
Yoruzu can’t understand why Sukuna brought such a disrespectful child into his home, but she doesn’t dare question the king. She focuses on directing his attention back to her movements, but Sukuna seems elsewhere.
It’s rare for someone to get under Sukuna’s skin, and he’s torn between wanting to keep his promise to the boy and to punish him for his insubordination. Perhaps he should have just killed him, and saved himself all this trouble.
Abruptly, Sukuna rips Yorozu from his lap and tosses her face first onto the bed. He fucks into her roughly, seeking his climax selfishly to distract from the feeling in his chest. Her screams echo loudly, and he’s sure Satoru can hear them down the hall.
Satoru can hear traces of the woman’s screams as he leaves. He hopes that Sukuna is killing her. She’d deserve it for how much she’s looked down on Satoru since they’ve met despite being only a human.
Instead of going to his room, Satoru decides to explore a bit instead. The corridors are tall and vast, and he feels small walking amongst them. He encounters some human servants as he wanders, and he’s pleased when they bow deferentially to him as he passes.
Once finished, Sukuna sends Yorozu off to her room. He changes into his training outfit and seeks out the young oni. He’s annoyed, but not surprised to see he isn’t in his room. Impatient, he tells a servant to inform Satoru of his location and waits in the training hall.
When Satoru has a servant tell him to meet Sukuna in the training hall, he's almost tempted to make Sukuna wait for him as well. Except, he's too eager to be trained by Sukuna to wait any longer, not even for his own sense of pettiness.
Sukuna is standing in the center of the room with both hands in his pockets. “You managed to wait after all, my little pupil.”
"I did, so you better be worth the wait," Satoru declares haughtily. He can't shake the feeling that he's been wronged by Sukuna, even if he's trying to gain something from him now.
“That all depends on the effort you make. I won’t go easy on you.” Sukuna warns before he rushes in close to Satoru.
“We are going to start with basic combat skills, without the use of techniques. It’s an important foundation for all fights. Are you ready?”
“That seems—” Satoru bites his tongue before he can say that it seems unfair. Sukuna is so much larger than him, and he has always had to rely on his technique to level the playing ground and compensate for his small size.
“Fine. I’m ready.” Satoru narrows his eyes.
“You’ve exhausted your energy fighting with me before. You have to learn to conserve it, and fight strategically.”
Suddenly, Sukuna grabs Satoru’s arm and kicks his leg underneath him, knocking the boy to the ground.
“Fight me off.”
Satoru makes a soft gasp as the air is knocked out of his lungs and he's pinned underneath Sukuna. He tries to push the large oni off, but there's not much he can do.
"I don't know what you expect from me," he says sourly.
“I expect you to try.”
Sukuna says calmly as he stays where he is. He doesn’t push further onto Satoru, nor does he let up. “If this was a real battle, it would already be over. Do you really want it to end so soon, so easily?”
With a frustrated exhale, Satoru tries to wiggle out from underneath Sukuna. "If this were a real battle, I would be allowed to use my technique," he says dryly.
“Stop arguing with me. Do you want me to train you or not?” Sukuna looks down at Satoru with a serious expression as he offers advice, “You have impressive abilities, but lack control of your energy. Remember our last battle when you used all your energy to heal and were left defenseless?”
"How exactly would this help me gain control of my energy?" Though his tone was disrespectful, Satoru is genuine in his question. He's sure that Sukuna knows more than he does, and that perhaps in neglecting his hand-to-hand combat abilities, Satoru has become ignorant of some aspect of his own technique.
“Last time we battled, you started using your technique immediately, with hardly any breaks in between. You need variety and to not exhaust yourself so quickly, and a way to continue fighting between techniques.”
It’s the most words Sukuna’s spoken to the boy, showing a genuine interest in explaining to him. “We will also train your energy management, but first we start at the basics.”
What Sukuna said makes sense to Satoru, but he’s still unhappy about the clear disadvantage he’s at. While he’s open to learning, no matter what he does, he can’t seem to be able to throw Sukuna off with his strength alone. If Sukuna were a human, even at his size, it should be doable, but his innate strength as an oni does nothing to help him against another, much larger oni.
So Satoru does what comes naturally to him next. He opens his mouth and bites down hard into the flesh of Sukuna’s forearms, his sharp teeth sinking past the barrier of his skin.
The boy’s teeth are surprisingly sharp, causing beads of blood to drop into Satoru’s mouth. He grins from the unexpected pain and shakes his arm to try to free himself. “I’m not surprised you play dirty, but you’ve got to use all the tricks you can, little one.”
Satoru growls at the bitter taste of Sukuna's blood, but he remains latched on even as he continues to squirm. He can't tell if he's getting any closer to escape, but he does take pleasure in making Sukuna bleed.
Sukuna shakes his arm roughly and rips off a bit of his own flesh to knock the boy off. He rubs at the wound, investigating the shape of the little teeth imprinted on his arm. “Trying to mark and claim me, hm?” He laughs and settles his weight heavier onto the young oni’s hips. His weight alone could crush Satoru.
Satoru’s gums hurt after being forcefully ripped off from Sukuna’s arm, and he whimpers a little as the weight on top of him increases. Pouting, Satoru looks away from Sukuna, unwilling to acknowledge his failure.
“Is this how you plan to fight me off— pouting like a little kid?” Sukuna mocks with a condescending tone as he tilts his head.
Glaring at Sukuna, Satoru finally concedes. “Fine. You’ve proven your point that you’re physically stronger than someone several times smaller.” He’s not sure what Sukuna expected from him in the first place.
“Good, now you’ve acknowledged your limitations and the training can really begin.” Sukuna eases his weight off Satoru and stands in the center of the room, braced. The bite mark on his arm has healed completely, as if it were never there. “I want you to punch me, as hard as you can.”
Satoru didn’t need to be told twice. With as much of the rage he feeels towards Sukuna as he can muster, he swings a punch at the oni king, his small fist landing on his stomach right below the giant mouth.
It’s a good, strong punch despite the boy’s small frame. Sukuna can feel the pure rage behind it, but he’s not bothered by that. “Not bad, kid. We’re going to spar, but I’ll go easy on you.”
Sukuna assumes a fighting stance, with his legs spread and both arms out. “Try to dodge.”
Just the hint of praise from Sukuna has Satoru feeling a little warm. He copies Sukuna’s stance and nods that he’s ready, his heart beating quickly.
Sukuna evens out the fight by only using two of his arms to land blows on Satoru. He’s decent at dodging though Sukuna hits him a few times in the chest. The entire time, he’s grinning, genuinely having fun playing with the boy.
Satoru matches Sukuna's grin, even though each hit he takes briefly knocks the air out of his lungs. "Where did you learn to fight?" he asks, one of Sukuna's fists swiping by his body and catching air.
“I taught myself.” Sukuna admits, “I’ve had to fight ever since I was young.” Maybe that’s what has him so curious in the boy, someone with a passion for fighting just like he had at his age.
That's not too different from him, Satoru thinks. It's hard to believe that someone with a reputation as terrible and vast as Sukuna was ever small like he is.
"If you're so strong, why do you bother to keep so many weaklings around?" Especially someone like the tadpole-browed woman.
“That’s rich coming from you. What makes you think they’re weak?” Sukuna challenges. It’s true he’s stronger than all of his partners, but nowadays it’s rare to even find an opponent worthy of his time.
“They’re not you.” Even Satoru is aware that his strength can’t compare to that of Sukuna, but he’s confident that he can match it one day. He can’t say the same for Sukuna’s companions.
“No one is.” Sukuna smirks. “But that’s not why I keep them around. Loyalty is important to me, and companionship.”
“If you want blind loyalty and companionship, you could get a dog instead,” Satoru declared haughtily.
Sukuna flicks the boy on the nose. “I’d like to put a collar on you, walk you around the shrine to put you in your place.”
Satoru bares his teeth at Sukuna. "I'd like to see you try." He'd run away before Sukuna could do something like that to him.
“We both know it would be easy for me to do.” Sukuna wraps his fist around the boy’s neck lightly to demonstrate. “But that’s not what I want from you.”
"What do you want from me?" Satoru's voice is level, as though he's not at all affected by the hand much larger than his head threaded around his throat. He knows he has been made into Sukuna's possession, but the details of their arrangement have yet to be made clear to him.
“A strong opponent, someone to fight with regularly so that I can test the limits of my strength.” Sukuna proclaims as his fingers wander along the boy’s clavicle. “And a lover.”
Drawn in by Sukuna's approval, Satoru recoils when he hears the word lover. "You can't possibly expect me to love you." It sounds ridiculous even saying it out loud.
“I don’t care if you love me, but I do expect you to submit to me in the bedroom.” Sukuna explains as calmly as if he were discussing the weather. “In exchange for living in my home, and being trained by me.”
"Submit in the bedroom?" Even as the words come out of Satoru's mouth, he can guess their meaning, and it makes him blush and look away from Sukuna. "I'll take that to mean I can be as defiant as I'd like elsewhere."
They’ve stopped sparring at some point, as Sukuna’s touches become more gentle on the boy. He finds himself drawn to him, unable to keep his hands from wandering. “You will still be punished for insubordination, don’t think I’ve forgotten about how you acted this morning.”
Satoru opens his mouth to dispute his punishment, but... It had happened within the confines of Sukuna's bedroom, which is apparently where Sukuna has jurisdiction over him. He purses his lips unhappily.
“Be good, and you won’t be punished.” Sukuna shrugs. “Now, we’re going to start you on a rigorous training schedule. I want your body in top shape.”
"What's the training?" Satoru tilts his head to one side. He'll take anything that can get him closer to the realm of Ryoumen Sukuna.
“You will run laps around the shrine each morning, and once finished you’ll do drills of push ups, planks, and burpees, all before breakfast. You’ll spend your days honing your techniques, mastering your energy control and power.”
"Breakfast better be good, then," Satoru mutters. Speaking of, he still hasn't eaten, and he peers at Sukuna expectantly through his lashes, wanting to be fed.
“You think you deserve breakfast?” Sukuna scoffs with a raised eyebrow.
"I can always find one of your servants to chew on..." Though after being fed cooked meat, the idea of tearing through someone who's still alive doesn't appeal to Satoru as much as it once had.
“Go ahead and try.” Sukuna threatens. “I'll slice your pretty little head off before you can finish them.”
"Punish me some other way," Satoru whines. He doesn't like being denied food.
Sukuna grins as an idea brews in his mind. “I will then, in a way I choose. Come to my room after breakfast.”
For some reason, Satoru feels that he'll like what Sukuna has planned even less than being forced to skip a meal, but he chooses to worry about that after he gets to eat.
"Can we eat now?"
“Mm.” Sukuna nods. The two walk to the dining hall together, where pots of green tea await them, as well as the three other concubines.
“Good morning, my king.” Uraume nods towards Sukuna. They don’t spare a glance towards Satoru.
Satoru tails after Sukuna excitedly, eager to see what new foods he'll experience that he's missed out on. He ignores Uraume as well, who may as well not exist at all to him.
Sukuna grabs Satoru’s arm and brings him atop his lap at the head of the table, much to the dismay of the other concubine. Yorozu especially, as her eyes burn like daggers at Satoru.
Sukuna hums, unfazed and pours them both a cup of tea and hands one to the boy.
Satoru isn't too happy about being made to sit in Sukuna's lap either when he's completely sober, feeling like Sukuna's treating him like a child. It's hard for him to ignore the glaring from the other concubines, so he stubbornly stares into the cup of tea he's been handed.
Breakfast is served sizzling and hot: miso soup, rice, salmon and lean human meat fried like bacon.
Before eating, everyone bows and says “Itadakimasu.” Sukuna pinches the boy, to make sure he complies this time.
"Itadakimasu," Satoru mumbles after glaring at Sukuna for the pinch. This time, he even waits for Sukuna to eat first before picking up some fried human meat with his chopsticks, drooling a bit from just the smell.
“Is breakfast to your liking?” Sukuna asks with a condescending tone after sipping his miso soup.
Satoru nods eagerly, too engrossed with his food to care about Sukuna's patronization.
Sukuna is pleased with the boy’s compliance and breakfast goes without incident. It’s almost a shame he’ll have to punish him afterwards, but Sukuna has to maintain order in the household.
Satoru has forgotten about his punishment after the meal, and Sukuna doesn't seem angry with him either, so he becomes complacent with the belief that he's safe.
After breakfast, Sukuna lifts the boy as he stands and holds him against his chest. He doesn’t set him on the ground, in case he tries to run away.
He nods as they exit and heads towards his bedroom at the end of the hall.
It's only when Satoru is being carried off that he realizes that while he has forgotten about being punished, Sukuna hasn't. His heart hammers in his chest the closer they get to Sukuna's bedroom.
It’s not until Sukuna closes the door that he turns to look at Satoru. He sits at the end of the bed and lays the boy on his lap, ass up and facing towards the ground. He pets along his back as he coos with a false kindness, “Do you have anything to say for yourself?”
Satoru doesn’t let his guard down this time. “I say that this wouldn’t have been an issue if you had proven yourself to be more trustworthy.” He tests the strength of Sukuna’s hold on him, and finds that he has no chance of escaping.
Tch.
Sukuna clicks his teeth loudly. The hand that was petting him turns violent, ripping his clothes apart to split at the middle, exposing the boy’s bare skin.
“You still have so much to learn.”
Without warning, Sukuna cracks his hand down onto Satoru’s asscheek, stinging the palm of his hand from the impact.
Satoru yelps from the hit, but what was worse than the pain is the sheer mortification from what Sukuna is doing to him. He’s seen human parents discipline their children like this, and it’s humiliating to be treated like one of them.
“Sukuna…” he sniffles, reaching behind himself to try and cover his exposed behind from Sukuna.
“Hm?” Sukuna asks as he swats Satoru’s hand away. He rubs the next cheek softly, marking his strike before lashing it down onto the boy harshly. The pale skin of his ass blooms red with the shape of Sukuna’s hand.
Satoru’s face is warm, but not nearly as warm as the flesh of his ass, throbbing with pain. At least Sukuna can’t see his face, the small tears threatening to spill from his eyes. His hips buck in an attempt to get further away from Sukuna’s hand.
Sukuna kneads onto Satoru’s reddened skin soothingly, “Do you see what happens when you act like a child?” He smacks lightly, more mockingly over a previous slap. “You get treated like one.”
The light slap wounds Satoru's ego more than the others, flinching as Sukuna's palm lands on his tender skin. Drawing his knees together, Satoru whimpers as he tries to make himself smaller, hiding away from Sukuna's prying gaze.
Satoru’s pale skin looks beautiful covered in red, like a stained porcelain doll. It makes Sukuna want to mark him, to leave his skin painted in reds, purples and yellows. Undeniable evidence of what belongs to him.
Sukuna coils his hand back to smack hard, echoing through the room and jolting the boy in his lap. Immediately after, Sukuna’s large hand cups his cheek to feel the warmth of his abused skin. He squeezes, fistful of the boy’s small, perfect, cheeks fitting so well in his grasp.
“I’m going to ask one more time. Do you have anything to say for yourself?”
Satoru shakes his head stubbornly, head dizzy with pain. He's digging his fingers into Sukuna's thigh, bunching up the fabric of his robes as he tries his best to stifle any cries of pain. He's not doing a very good job of it.
Shutting his eyes, Satoru wills for his punishment to be over. His ass feels like it's on fire, and even though Sukuna is no longer striking him and merely squeezing his flesh, it hurts enough to force the tears from his eyes as his small body shakes with barely suppressed whimpers.
Sukuna can feel the boy shake beneath him, and practically holds his breath to focus on the pathetic whimpers he’s making. It makes his dicks twitch with interest as he massages Satoru’s swelling cheek.
“So stubborn.” He clicks his teeth, and cracks again, determined to make the boy apologize no matter how many strikes it takes.
Satoru sobs out loud at the new hit, each strike compounding on the pain of the last one. His tears dampen Sukuna's robes. He starts struggling again, body wiggling in an attempt to escape. But he couldn't free himself when Sukuna pinned him earlier that day, and he's no closer to accomplishing it now.
“Shh…” Sukuna coos as he presses Satoru down to prevent escape. “I can make all the pain go away, my sweet boy. All I need is for you to apologize for your behavior this morning.”
Satoru keeps shaking his head. He doesn't want to apologize to Sukuna for something so trivial, and he'd rather withstand the pain than admit to being wrong. He also doesn't trust Sukuna to make him feel good when the last time resulted in him being hurt as well.
Sukuna grits his teeth. The boy might be more trouble than he’s worth, with his bad manners, entitlement and stubbornness. But still, Sukuna isn’t ready to kill off his new plaything just yet. He takes a deep breath and pets along Satoru’s back gently.
“Satoru, I don’t want to have to hurt you anymore, don’t you understand?”
Sukuna has stopped hitting him, so Satoru goes still to show that he is listening, turning his head so he can look at Sukuna through his teary eyes. He wants to believe that Sukuna doesn't want to hurt him, but it's hard when his butt is still burning with pain.
Sukuna’s breath hitches when he sees those magnificent blue eyes wet with tears. The boy’s beauty is unlike any he’s ever seen, like a rare gem too precious to break completely.
“I would much rather make you feel good…” his hand wanders towards Satoru’s thin hip bones with a gentle touch, tips of his fingers grazing his groin. “Like when I touched you before, do you remember?”
Satoru shivers at the touch, the memory of blinding pleasure weakening him. He nods hesitantly. He likes the pleasures that Sukuna has introduced to him: the cooked foods, desserts... even when Sukuna touched his penis until it felt like he had to pee. When Sukuna made him cum. But Sukuna also keeps demanding things from him, and he doesn't like relenting.
“Do you want me to do it again?” Sukuna’s voice is sweet like honey as his hand inches forward until he’s palming the boy’s small cocklet. “What if I used my mouth, like you did for me? It feels even better.”
Satoru's eyes are wide, and this time he's trying to move his hips into Sukuna's touch. Blood is rushing to his nether regions, to his warm behind that stings from the air touching it, and to his penis in Sukuna's large hand.
Sukuna flips Satoru onto his back on the bed and hovers on top of him. He ghosts along his prick, breathing hot against it before planting a kiss onto the head. He looks up at the boy and whispers against his small shaft, “Just promise not to barge into my room like that again, or insult your fellow concubine and I’ll make you feel really good.”
Satoru's mouth hangs open from the stimulation to his penis, Sukuna's light breaths on his prick makes his stomach clench in anticipation.
"I won't barge into your room again," Satoru promises. He won't willingly go into a place where he has no rights over Sukuna anyway, now that he understands the expectations placed on him.
“And?” Sukuna presses as he licks along the boy’s shaft with a slow drag of his tongue. Then he puts his tongue back in his mouth and stares at Satoru expectantly. “Unless you want me to stop…”
"But they insult me too," Satoru whines. Even if it's not to his face, or with their words, he knows that all they see when they look at him is a foolish little boy. Thinking that they are better than him.
“Do they? I bet they’re jealous of you.” Sukuna can’t help himself as he wraps his tongue around the boy, and encloses his mouth around him. He’s smaller than his tongue, it’s more like sucking on a clitoris than a cock. Sukuna hums at the sweet fleshy taste, sending vibrations along Satoru’s little prick.
Satoru moans weakly as he's taken into Sukuna's mouth, pressure building beneath his navel. His butt still throbs with pain, but instead of detracting from the pleasure, it adds to the overwhelming wave of feelings washing over him. His mind is numb as Sukuna toys with his small prick, massaging every inch of it all at once.
Sukuna knows he shouldn’t indulge the boy like this, after all he didn’t apologize, and he’s avoiding the topic of the other concubine. But he’s so sweet underneath him, moaning as Sukuna takes him that he can’t possibly stop. He swirls his tongue around his small length, hollowing his cheeks as he sucks lightly.
His hand wanders down the boy’s taint, prodding curiously at his tight rim, “Don’t worry,” he whispers between breaths, “today you’ll only receive.”
The pleasure is too much for Satoru, who writhes on the bed. Drool leaks from his mouth, his tongue heavy and useless as he tries to utter Sukuna's name. His hips buck as Sukuna continues to suck him, and he can tell that he's about to cum.
Sukuna is keenly aware of how the boy’s rapidly approaching climax, lost in the pleasure as he writhes underneath him. Not wanting to rush, Sukuna releases his little prick with a wet plop and a grin as he stares at the drool glistening on his lips.
Then he sucks on his finger to wet it, before probing at Satoru’s rim. “Deep breath…” he coos before pressing inside, sliding all the way in until he feels the rubbery piece of flesh on the pad of his finger.
So distracted by Sukuna's mouth on his prick, Satoru hadn't noticed the finger pressed against his hole until it's pushing inside him. His body goes still, thighs shaking from the discomfort. But Sukuna doesn't take long to start pressing against something inside him that brings dizzying pleasure. It feels almost like his penis is being touched from the other side, but even more intense. His dick jumps, and he's so close to cumming.
Sukuna watches the boy with unblinking eyes, the flush on his pale cheeks, the haze in his eyes. It’s rare for him to give without taking, but seeing the boy unfold before him is a gift in itself, and a preparation for more to come. Sukuna curls his finger slowly, coaxing him to open as he takes his throbbing prick back into his mouth.
The moment Sukuna's mouth is back on him is too much for Satoru, his back curving as he's made to cum.
"Sukuna..." he cries when the other doesn't stop stimulating him even as he's convulsing with orgasm. "It's too much!" He's not sure how much more of this he can take.
Although his orgasm is dry, Sukuna can still taste the raw pleasure of the boy’s first prostate orgasm as he curves underneath him beautifully.
Possessed, Sukuna wants to pull more, to have the boy crying and begging to be filled, to have him cumming on his cock. But Sukuna decides better of it, for now, in order to train the boy and turn him into the little nymphet he desires.
“Hm?” Sukuna hums as he releases his finger and tongue. Without wiping his face clean, he leans forward to kiss Satoru’s wet, open mouth.
Satoru eagerly parts his lips for the kiss, breath heavy as he welcomes Sukuna’s tongue inside his mouth. His body grows hot the longer Sukuna kisses him, and he’s squirming underneath him with slowly building arousal, a feeling that is still foreign to him. He thinks of Sukuna touching his penis, his nipples, even inside him, and moans softly. He’s suddenly too shy to ask for more, even if he’s never had any problems demanding what he wants from Sukuna.
The kiss is intoxicating, leaving Sukuna drunk on the taste of the boy’s breath and spit. Panting against his petal soft lips, he whispers, “My sweet boy, isn’t it better like this?” His hands trace along Satoru’s body, exploring the curves and ridges of his chest and sides. “There’s so many things I can show you, if you stay good for me.”
“Show me,” Satoru whispers, drunk off pleasure. He likes when Sukuna touches him like this, even if he’s a little ticklish. Heart racing, he wants to cum again, to have Sukuna keep making him feel good. Staring into Sukuna’s eyes, Satoru whimpers needily.
Sukuna’s eyes widen as he looks at the ruined, needy state of the boy. “I will.” He brushes a hand along Satoru’s lips then slips two fingers inside. “Suck.”
Satoru obediently sucks on Sukuna’s fingers, eyes wide with anticipation. He’s drooling and making a mess, but he’s too far gone to care about what he looks like.
“Good boy…” Sukuna coos as he pets Satoru’s velvet tongue. “You’re so pretty like this.” His other hands continue to explore his body, memorizing the shape of him.
Satoru’s stomach flips as he continues to suck on Sukuna’s fingers, a warmth spreading from his gut to his small prick. He preens from the praise, a heady drug that makes him loose-limbed.
Sukuna slowly removes his fingers, a trail of spit connecting to the boy for a moment. Then he presses his wet fingers against his rim, easing two in slowly, with ease.
Satoru finds that the feeling of being spread apart on Sukuna’s fingers is still uncomfortable, but he shifts his hips in hopes of helping Sukuna find the part of him inside that feels good.
Sukuna finds it with precision, and rubs small circles with the pads of his finger in languid swipes. He feels the boy opening up for him with every press, so warm and inviting.
Satoru moans as he sees stars, his body readily accepting Sukuna's fingers and the pleasure they bring him.
"Sukuna, it feels good...!" He's still drooling even without the fingers in his mouth, his eyelids fluttering.
“Yeah?” Sukuna scissors his fingers inside the boy’s tight, warm walls to stretch him. He’s so pliant and opening up for him so willingly, Sukuna can’t help but ache to be inside him. “Do you want more?”
"More," Satoru pleads, his thighs falling apart. He's so close to cumming again, but he's somehow not able to, and it makes him tear up in frustration. He moves his arm to try to touch his penis, to give himself the push that he's missing.
Sukuna ignores the boy’s needy little prick in favor of kissing along his neck, sucking on the pale skin to decorate Satoru in shades of red and purple. As he sucks, he inserts a third finger, feeling the tightness as he’s engulfed. He waits to feel the walls relax before he’s pumping into the boy at a faster pace, striking his prostate with every thrust.
“I want you to cum like this, from the feeling of me inside you,” he whispers, breath hot against his skin. “Can you do that for me, Satoru?”
"I- I don't know," Satoru whines. His penis is so hard that it hurts, but he can't seem to be able to cum from just Sukuna's fingers. There's a slight burn from how wide he's being stretched, but it comes second to the pleasure making his thoughts fuzzy.
"Sukuna, please. I need..." He needs Sukuna to just touch his prick.
“What do you need?” Sukuna asks between kisses down the boy’s neck towards his chest. He flicks his small pink nipple with his tongue as he watches the desperation in his face, fingers thrusting in relentlessly, making a wet, squelching noise. “Tell me.”
"Sukuna..." Satoru's stomach is drawn tight, feeling like he's on the verge of bursting at any moment. He cries from how full he is, spread apart by Sukuna's fingers. "I want to cum," he complains.
Sukuna reaches into his bedside drawer to grab a bottle of lube which he generously smears on his throbbing cock. “Perfect boy…” he coos, as he slides out his fingers and lines his cock before the boy’s stretched hole. “I need you.” With a low moan, Sukuna presses past his rim slowly.
Satoru is afraid as Sukuna’s cock sinks inside him, but he’s loose enough that it enters him easier than it ever has. His arousal relaxes him, and he wants to know what it’ll feel like to have Sukuna’s thick cock press against that spot.
Satoru reaches out to Sukuna until his hands are wrapped around the larger oni’s horns, gripping them tightly as he tries to get used to being split apart.
Despite being stretched, the boy is so tight that Sukuna’s arms are shaking as he pushes deeper inside, pressing against Satoru’s prostate within moments. “Taking me so well…” he praises as he presses his hand on Satoru’s belly to feel the bulge of him inside. “Do you see?”
Satoru's eyes widen when he sees proof of how much Sukuna is filling him, pushing against his stomach from the inside.
"So b-big," he hiccups, his throat dry. It's more than uncomfortable and being stretched so far hurts, but more than anything the pressure on his prostate makes him feel overwhelmingly good. He tugs harder at Sukuna's horns, trying to keep himself grounded.
“Perfect for me.” Sukuna moans as he presses his cock in deeper to fill Satoru completely. He opens the smaller mouth on his hand and takes the boy’s neglected prick inside it right as he starts to move his hips.
Satoru cums with a strangled cry, the mouth enveloping his dick all he needed to finally orgasm. As always, nothing comes out of his penis. His walls clamp down on Sukuna’s cock, still carving its way further inside him.
Sukuna murmurs a litany of praises like good boy and so pretty when you cum as he drags his cock out slowly, barbs dragging against Satoru’s walls. His hand rests lightly on Satoru’s prick, keeping him warm under his palm. “You’ll make me feel good like I did for you, right my sweet boy?”
Satoru winces, the hand on his dick is a little painful and overstimulating. Uncomfortable from the barbs poking inside him. Sukuna’s praises makes his head feel mushy, and he feels compelled to please him, even though he’s overwhelmed.
“Can you… be gentle?” he asks, sounding small and unable to look Sukuna in the eyes. The spines don’t hurt when Sukuna takes it slow with him.
Sukuna grabs both of Satoru’s hands and pins them above his head. Leaning down to kiss him, Sukuna assures against his lips, “Yes, I’ve got you.” He rocks his hips slowly, fucking slow and deep. It’s sensual, very unlike before.
Satoru's mouth falls open on its own, offering himself to Sukuna's exploring tongue. He's crying from how intense everything feels, and how he can't tell where he ends and Sukuna starts. Even with how slow Sukuna is thrusting inside him, the barbs dragging against his walls still sting.
Sukuna kisses the boy’s tears as they fall, whispering praises with a broken voice as his orgasm builds. It’s hard for him to go slow and his arms shake as they hold Satoru’s hands in his own, interweaving his much larger fingers between the boy’s. His second cock slides between his cheeks, grinding against his smooth skin with every thrust. As much as he wants to fit both inside, he knows that Satoru isn’t quite ready.
A few more thrusts, and he’s cumming with a shuddered moan, spilling inside and between Satoru’s cheeks to coat him in his seed. Like he’s coating him, claiming what belongs to him.
Satoru stares in awe as he's filled to the brim with a warm liquid, his stomach curving outward even more. He's impossibly full, but he's also pleasantly lightheaded, his legs almost numb.
"What is...?" Satoru slurs his words. "What is this?" The act that they've done together, the warmth between his legs. He wishes he had words for all of them.
Sukuna releases his hands and looks down at Satoru with a smile. “This?” He swipes some of his cum with his pointer finger and presses it before Satoru’s mouth to taste. “It’s semen, or cum. When you’re older, it will come out of your penis, too.”
Satoru accepts Sukuna's finger into his mouth, his brow crinkled as he licks it cautiously.
"What is it for?" he asks innocently, eager to learn more from Sukuna.
Sukuna has never had to explain such simple concepts to someone before, but there’s something erotic about telling the young oni what’s covering his body. What it means. “It’s a seed, for making babies.” He holds his hand over the brand on Satoru’s belly possessively. “If you were a girl, you’d swell right here… imagine the fearsome creatures we’d make.”
"Making babies..." Satoru's eyes widen as he considers the implications. He's suddenly glad he's not a girl, which isn't something he's thought of before. Having a baby is too terrifying and foreign a concept for him. He eyes the brand on his stomach suspiciously.
Sukuna laughs at Satoru’s reaction. “Would you like that? To carry the child of the king.” His fingers trace the mark on his stomach as he speaks.
Satoru profusely shakes his head and tries to inch away from Sukuna. It's difficult with the other still inside him, the barbs on his cock preventing him from pulling away. Satoru's body is also tired from their training, and from cumming twice.
“That’s what it’s for biologically anyways, but it also just feels really good to cum.” With a little smirk he adds, “As you seem to have figured out.”
Sukuna sits upright on his hands and looks down at Satoru. “I’m going to pull out now, I’ll heal you immediately afterwards, so be patient and don’t fight me. Ready?”
“I can heal myself.” Satoru pouts, miffed at being treated like a helpless child. He’s gross and sticky from Sukuna’s cum, but he has no desire to move to clean himself. His limbs lay heavily by his sides.
“Satoru.” Sukuna grunts with an annoyed expression. The barbs drag along the boy’s walls as he slides out, spilling cum to mix into the wet pool collecting underneath Satoru. Without allowing him to complain, Sukuna slides two fingers into his hole to repair the damage.
For some reason, Satoru finds Sukuna’s cum leaking out of him embarrassing, and he tries to close his legs to stop it from happening. At least while Sukuna is still here and looking at his entrance
He gasps from the fingers in his sore entrance, but his pain quickly goes away.
Sukuna licks his fingers clean once he finishes healing Satoru’s damaged walls. “You look so pretty like this, covered in my cum.” He crawls away from Satoru and stands up, towering over him from the side of the bed. “But it's time to get up, go bathe and make yourself presentable for lunch.”
Satoru feels cold when Sukuna leaves him. Even though he's no longer sore, he can't find the will to leave Sukuna's bed. If anything, he wants to slide under the sheets and hide beneath them.
"Do I have to?" The idea of making himself presentable dismays him, and he looks at Sukuna sadly.
Sukuna furrows his brow as he looks down at Satoru. His small neck is covered in hickeys and bruises and the semen oozing out of his ass looks obscene as it dries on the sheets. His white hair is disheveled and the flush on his cheeks makes his blue eyes more vibrant than usual, their sad expression stirring something foreign within the oni king. “Stop being difficult and get up.”
Satoru sniffles and curls into himself. “I don’t want to,” he says quietly. Even if it means that he won’t be able to eat, Satoru really can’t bring himself to move. He’s a mess, and he can’t help but resent Sukuna a little for how used he feels.
“Come here,” Sukuna sighs and places his arms under Satoru to cradle him across his chest. Cum leaks from the boy into his forearm as he holds him close.
Satoru rubs his cheek against Sukuna's chest as he's held. It makes him feel childish, but it also lessens the coldness claiming his body. He's holding in tears that he hadn't known had formed, completely quiet for once.
Sukuna carries the boy to his bathroom, holding him close as he runs the warm water. Once the tub is filled, he gently lays Satoru in the water and joins him inside. He leans his head against the side of the large, wooden tub and closes his eyes for a moment, looking at peace.
Satoru sighs as he’s submerged in warm water. There’s an emptiness inside him reminiscent of the night they consummated their bond, except he doesn’t understand why. He mostly enjoyed it this time, and it didn’t hurt nearly as much, so shouldn’t he be in better spirits?
The boy’s quietness doesn’t go unnoticed by Sukuna. He opens his red eyes and looks at the small oni in the tub. “Come here,” he beckons. “Let me wash you.”
Sukuna talking to him helps Satoru snap out of his weird mood, and he eagerly moves towards Sukuna, craving attention.
Sukuna brings the boy onto his lap and pours water onto his hair gently. He lathers his hands with shampoo then massages into Satoru’s white hair, taking his time on the strands with soft hands.
Any lingering desolation in Satoru's heart melts away from Sukuna's fingers massaging his scalp, and he has a small smile as he basks in the attention. The way Sukuna bathes him makes him shiver in delight, so much more pleasant than what Uraume had done for him.
Sukuna hums a song as he washes his concubine with a tenderness unlike himself. He rinses the shampoo and places a kiss atop Satoru’s crown once finished. Then he wets a cloth and begins cleaning his shoulders, admiring the red marks littering his pale skin. He doesn’t speak, enjoying the serenity of the moment as warm steam billows around them.
Satoru leans into Sukuna's touch, trying to steal as many drops of affection as he can. He's being spoiled and he enjoys it, having never been treated so tenderly before. There's a strange emotion swirling in his chest, a softness that is foreign to him. Something that only Sukuna has managed to bring out of him.
Once he’s finished cleaning the boy, Sukuna tilts his face up to plant a chaste kiss on his lips. “Better?”
Satoru nods, upbeat once again. His lips tingle from the kiss Sukuna left, and he wants to be treated like this all the time. This side of Sukuna is not one he hates, and one he may even seek out in the future.
“Good.” Sukuna says simply as he begins washing his pink hair. He leaves two arms wrapped around Satoru’s small frame to keep him close. “I want you to be happy here.”
“What’s for lunch, then?” Satoru peers up at Sukuna through his lashes, pressing even closer against Sukuna’s warm body.
The return of Satoru’s bratty tone brings an unknowing smile onto Sukuna’s face. “Let’s go find out.”
He lifts Satoru out of the tub with himself, not wanting to release the wet, warm body that clings to him.
After getting dressed, the two saunter into the dining hall late for lunch, much to the dismay of the disgruntled concubine made to wait. Sukuna takes his seat with Satoru warming his lap as before, as if he belonged there.
Piercing gazes stare at the boy so close to their king, the hunger making their agitation more apparent. There’s a new favorite in the shrine.
Chapter Text
After lunch, Uraume bows before Sukuna.
“Hello, my lord.” Uraume says flatly, face unreadable. “May I speak with you, privately?”
Sukuna nods and shoos Satoru away with his hand.
Uraume bows again once they have been granted a private audience with the king.
“I and the other concubines have… reservations about Satoru, my lord.” They keep their tone deferential, knowing that the small oni is currently favored by the king. “Will you allow me to convey our misgivings?”
Sukuna’s cheerful mood simmers down to a low annoyance as he looks down at his most trusted concubine. He lights up a pipe, smoking it idly as he examines their expression. “You have my attention.”
"My lord, we are concerned that Satoru is not fit to be one of your honored concubines as he is now." Uraume keeps their head respectfully inclined, eyes looking down and away from their king. "We believe that further training and discipline may be required to make him worthy of being by your side, my lord."
“Is that so?” Sukuna puffs his pipe thoughtfully as he listens. With smoke billowing out between his fangs, he grins, “Perhaps you could assist in his training my dear Ura.”
“I would gladly help train the boy, my king.” They’re relieved that Sukuna is receptive towards their criticism of his current favorite. “I request that you allow me to discipline him for his ill manners as well. And for the disrespect he has shown towards you both to your face and behind your back.”
Sukuna’s eyes narrow, “What has he said?”
"He shows you no respect, referring to you by your first name only. And he—" Uraume pauses, hesitant to speak further. "I do not believe what he has called you is fit for polite conversation."
“Go on.” Sukuna presses. The situation is mildly amusing, as he’s sure Satoru is as unruly behind his back as he is to his face. The boy isn’t one to put up a front, even in the face of the king. “Tell me what he said.”
Uraume is suddenly uncomfortable. Even though they are only relaying what the kid has said, they still struggle to say those profane words. "He called you the 'king of piss,' and not only that, but he has also threatened the lives of his fellow concubines countless times."
Sukuna snorts and almost coughs when he hears Uraume say piss. The childish insult sounds so foreign with their polite and formal tone that it’s hard not to laugh. “He’s the one that peed,” Sukuna mutters crudely.
The break in his stoic expression is brief, and he sits upright to collect himself. Threatening the lives of his possessions is not something he takes lightly, regardless of his fondness for the young oni. “I would never allow that to happen.” he assures.
"He needs to be punished for his insolence," Uraume declares. "May I suggest public lashing? Or perhaps being sent away to eat with the servants until he learns proper etiquette."
The embers of his pipe sizzle as Sukuna contemplates. Uraume has always shown strong judgment and has never wavered in their loyalty towards him. However, their words bring an agitation in his stomach. The imagery of the boy’s reddened cheeks and tear stricken eyes flash through his mind, and with it a burning possessiveness.
“No, that is unbefitting. What the boy needs is guidance from his fellow concubine, even from one that would rat out the other.” He spits venomously.
"I—" Uraume falters, heart rate spiking at being called a rat by their beloved king. "I'm sorry, my lord. I've overstepped."
They can't believe that Sukuna favors the boy enough to ignore their counsel. But if Sukuna believes that he was wronged, then Uraume has wronged him, so all they can do is apologize for their error. Never before has something like this happened, and resentment kindles within them for the troublesome child who has been creating a rift between them and their king.
Sukuna snuffs out his pipe with a scowl. “You can make up for your behavior by assisting in a lesson for the boy tonight.”
Uraume bows, even deeper than before. "Of course, my lord." They don't bother to ask what lesson Sukuna has planned; they will be fulfilling their duty no matter what.
Sukuna reaches for their hand, his agitation subsiding as it’s replaced with anticipation for the evening. “You’re so good for me, Uraume. I trust you’ll do an excellent job.”
“I won’t disappoint you,” Uraume promises. They can’t afford another mistake if they intend on keeping their status as Sukuna’s most trusted concubine.
After dinner, Sukuna looks down at the little oni in his lap. He tucks a strand of Saroru’s hair back behind his ear, “I have a special training arranged for you tonight my boy.”
"Special training?" Satoru smiles at Sukuna, equal parts eager and curious. He hopes that the training being special means that he'll be learning more than standard hand-to-hand combat skills this time.
“Mm, with your dear acquaintance Uraume.” Sukuna says with a sly grin.
It may not be the training the young oni desires for now, but Sukuna hopes that with enough exposure he’ll soon be begging for more.
At the sound of their name, Uraume perks up. They smile weakly at the boy, eyes unmatching the expression.
Satoru’s face falls when he sees Uraume, the wind leaving his sails.
“Does it have to be with them?” he whines petulantly. Uraume’s only a human, so he has no idea how they could possibly help train him.
“Don’t be like that.” Sukuna clicks his teeth. He stands up with the boy in tow. “There’s still so much for you to learn.”
"Like what?" Satoru asks, head tilting to one side curiously. He wants to know what he can look forward to this evening. Maybe they'll be using Uraume as target practice.
“More ways to serve as your king’s concubine.” Sukuna explains, a grin growing on his face. He grabs Uraume’s delicate hand and leads them towards his bedroom.
Satoru pulls a face. "You're tricking me again." He's more than disappointed by Sukuna's answer and all the false hope he had for actual training. Dragging his feet behind him, Satoru expresses his displeasure.
Sukuna chuckles, “No tricks today my little one. But you will do good and listen to Uraume, they’re your elder and have much to teach you.”
The king undresses and lays on his back on the bed, sprawled and exposed. Everything about him is massive, from his four strong arms, thick, toned abdomen and inhumanly large cocks laying proudly across his stomach.
Uraume turns to Satoru, “You will mimic my actions, just try to keep up.”
They begin to undress, exposing a feminine form. Slim, pale and delicate with small, perky breasts and a pink cunt between their legs.
Satoru hardly spares Uraume's form a second glance, other than a passing curiosity about how different their crotch looks compared to his. He's more interested in Sukuna's body, sturdy and powerful compared to Uraume's almost fragile appearance.
He bristles at the condescension in Uraume's words, that the human would dare to think they are his better in any way. Puffing his cheeks childishly, Satoru starts taking off his clothes as well, not wanting to be outdone.
Sukuna leans on one arm and watches intently, staring mainly at Satoru. Even though he already had him this morning, the sight of his smooth, hairless form as his cock twitching with interest.
With two fingers curling, Sukuna beckons both of them towards his lap.
Uraume is the first to answer the call, settling into Sukuna’s lap with practiced ease. They turn their head to give the boy a haughty look over their shoulder.
Satoru is more hesitant. He’s apprehensive about letting Sukuna touch him again so soon, worried that he won’t be as gentle. He approaches the bed and stands there awkwardly.
Uraume saunters towards their king with a sultry sway of their hips, clearly comfortable with their body. They crawl onto the bed eagerly, and grab a half hard cock between their slender fingers. “Come, Satoru.” They encourage and nod towards the lonesome cock awaiting the boy.
Satoru’s brow furrows as he gets on the bed. He sits on his knees next to Uraume, then looks at Sukuna for reassurance. He suddenly needs Sukuna to tell him that he’s stronger and more important than Uraume is, even though he already knows that to be true.
“Go on my boy.” Sukuna’s voice is low as Uraume begins mouthing along his length, licking and kissing the shaft as her hands jerk at the base.
Satoru stares at Sukuna pitifully before giving his cock a shy little kiss. He's irritated by how close Uraume's head is to him, and wishes that they weren't here.
“A mere kiss isn’t enough to please the king.” Uraume chastises. Showing off, they wrap Sukuna’s cock between their lips, bobbing their head to take his massive length down their throat. Sukuna moans, fueling Uraume with pride. They know that while Satoru may be the current favorite, they’re the one Sukuna will always come back to.
Glaring at Uraume, Satoru parts his lips and takes Sukuna's cock inside his mouth. He doesn't go very far down, conscious of the barbs as always. Running his tongue along the length of Sukuna's cock, Satoru keeps scowling at Uraume, no longer paying Sukuna much attention.
Sukuna runs a hand through Satoru’s hair, petting him encouragingly. “That’s it.” He murmurs as he twitches inside the boy’s small mouth. “Both of you are so good to me.”
Satoru is able to pretend that Sukuna is only speaking to him, and he hums happily from the praise. He eases his mouth further down Sukuna's cock, the blunt end of the barbs poking at his tongue.
Sukuna’s eyes flutter and he leans on his arm, enjoying the two mouths on him.
Uraume watches Satoru, red eyes burning as they take Sukuna’s cock deeper down their throat, slobbering around his length greedily. Their hand wraps around the base, jerking in time with the bobbing of their head so that no inch of Sukuna is left untouched.
Satoru copies some of what Uraume is doing, circling his small fingers around as much of Sukuna’s cock as he can fit. He bobs his head slightly, wincing as his tongue is cut on the spines. A few red drops spill from the cut, and Satoru sulks at the taste of his own blood.
Sukuna’s cock is too big and unwieldy for him to do anything with it comfortably, but Satoru does his best.
Uraume’s mouth is skilled, and soon Sukuna is spilling down their throat with a shiver and a low moan. Uraume swallows it all, then gasps for breath. Their lips are swollen and bloodied, but their face is serene. “You taste amazing my lord, tell me what else you want me to teach Satoru?”
Sukuna reaches for his concubine with a loving hand and brings them close to his face for a kiss. “Ride me Ura, show him how well you take me, how much you love my cock.”
Satoru’s jaw is sore and his eyes teary from the small cuts on his tongue. He’s also put out by how much more attention Sukuna is offering Uraume, his pride suffering in silence. Withdrawing from Sukuna’s cock, Satoru whines unhappily. He doesn’t want to be here anymore.
Uraume smiles into the kiss. The boy is just a new toy, whose novelty will run dry eventually. They, on the other hand, are Sukuna’s most trusted concubine, and far more skilled than the young oni.
Uraume reaches between their legs, grabbing Sukuna’s upper cock and angling it against their wet cunt.
“Satoru,” Sukuna purrs when the boy whines, “Come up here and sit on my face, I want to taste you.”
As he speaks, Uraume sinks down onto his cock, taking him with practiced ease. They moan from the stretch and begin rolling their hips at a slow, rhythmic pace.
Satoru’s spirits lift some from Sukuna talking to him directly. He nods shyly then crawls up to Sukuna, craving his praise and attention like a flower craves the sun.
“Sit how?” He’s not sure what to do here, so he eagerly waits for Sukuna's instruction like a good pupil.
Once the boy is in reach, Sukuna grabs him and sits him atop his mouth, facing Uraume. “Like this…” he murmurs against his skin as he presses a kiss onto his soft cheeks. His tongue drags between his slit, licking him in one long swipe.
Satoru squirms, ticklish from the way he’s being licked. He can see that Uraume has briefly stopped their bouncing on Sukuna’s lap to glare at him. Satoru sticks his tongue out at them in retaliation, but he’s unable to sustain the expression for long as Sukuna continues to lick him intimately.
“Don’t stop, Ura.” Sukuna spits out before he circles his tongue around Satoru’s rim. He’s still loose from this morning, and Sukuna moans as his tongue slips into his little hole.
Uraume is frustrated as they bounce on Sukuna, allowing his barbs to rip at their walls with each thrust. They’ve become accustomed to the pain, needing it to get off as the pleasure mixes with the violence so sweetly. But they’ve never sat on Sukuna’s face like that, and their eyes are narrowed as they watch the bliss across the young oni’s face as the king selflessly pleasures him.
Satoru shudders as Sukuna's tongue snakes inside him. Shaking his hips unconsciously, Satoru seeks out the pleasure that was introduced to him earlier in the day. His small thighs are almost engulfed by Sukuna's hands as they hold him steady.
Sukuna flattens his tongue to press the rubbery walls against Satoru’s prostate. He drags his tongue in a circular motion, feeling the boy convulse on his mouth. He wonders how many times he can bring him to orgasm, becoming addicted to the way his small body shakes with pleasure.
Satoru slumps forward as pleasure ignites his veins, and he's forced to hold himself upright with his hands braced against Sukuna's chest. He's completely forgotten about Uraume, too overcome with pleasure to care about anything other than the tongue inside him. His small prick aches as he's coaxed into arousal yet again on the same day.
Jealousy urges Uraume to ride Sukuna even harder, their inner walls being torn apart with the force of their bounces. But even with how intensely they ride Sukuna and the blood leaking from between their legs, their king remains preoccupied with the small boy perched on his face.
Sukuna takes the boy’s hardened cocklet into the mouth on his palm and sucks lightly. As he trembles on his tongue, Sukuna recalls the words he used to Uraume behind his back. The threats against Sukuna’s possessions and how unruly and disruptive he’s been within the extravagant walls of his home. He’ll make the boy pliant before punishing him, he decides.
Eyelids fluttering, Satoru's entire body shakes as he rapidly approaches orgasm.
"Sukuna..." he moans between harsh pants. No matter which way he moves his hips, he can't avoid the overwhelming pleasure of Sukuna's mouths on him.
Uraume doesn’t understand how this is a lesson for the young concubine. “My lord…” they start, but they bite their tongue and watch. They can feel Sukuna twitch inside their bloodied cunt, but it seems to be more from Satoru’s reactions than anything they’re doing. Instead of seeing the boy be punished, they watch as pleasure contorts his young face. But still, they don’t relent, using their hands to jerk Sukuna’s other cock as they ride their king.
Sukuna hums approvingly against Satoru’s slit, making a mess of spit on his face and chin as he devours him with two mouths.
Satoru doesn't last much longer and he shudders through an orgasm. His body feels weak as he falls onto his front. He doesn't realize that he's being punished, so he gives Sukuna a dazed smile once he's recovered enough.
"That felt good," he says quietly. Satoru kind of wants to snuggle up to Sukuna now, but he's suddenly reminded that Uraume is still here, and he pouts unhappily from his soured mood.
“Move out of the way, Uraume.” Sukuna says coldly. They look at him with wide eyes, and hesitantly lift off from his cock. There’s blood all over their pale thighs as they lift and hover like a wounded animal.
“Take the further one, and help Satoru to rock his hips properly.”
Sukuna lifts the boy from his face and spears him right onto his cock. It’s a tight fit with their two bodies pressed close together, but Sukuna can’t be bothered to care.
Satoru shrieks in pain at the sudden penetration, Sukuna's cock forcing its way inside him all at once. Although he's somewhat loose from being fucked earlier in the day and from Sukuna's tongue, he's still far from ready to take Sukuna's entire punishing length.
Uraume's eyes widen at the boy's scream. Knowing that their king has been fucking the child and seeing it happen are two different things. Satoru's small body is clearly not meant to be used in such a manner, and they would almost pity the kid if it weren't for how infuriatingly bratty he is. Instead, they lower onto Sukuna's waiting cock and do what they can to diffuse Sukuna's anger.
“Stop with that awful noise. This is what you deserve for threatening your fellow concubine. You think I wouldn’t find out?” Sukuna spits. His kindness has expired, as his anger bubbles up in a delayed reaction. He feels tricked by the young oni, intoxicated by his sweetness.
“Grab onto Satoru’s hips and show him how you do it.” He instructs Uraume. “You’ve always been the best at pleasing me, Ura.” He tacks on a little praise to sweeten the deal.
Any amount of pity Uraume held for the boy dries up at the sweet praise they receive from their king. Rocking their hips and clenching around Sukuna the way they know the oni king likes it, Uraume seizes Satoru's hips and forces him to move in tandem with them. Dragging the boy up and down Sukuna's cock, Uraume's red eyes darken at the sight of blood leaking from Satoru's thighs. The boy doesn't stop wailing even after being reprimanded. How uncouth.
Anything resembling bliss and affection from earlier is gone as Sukuna rips the boy apart on his cock. He leans back leisurely as he watches the tears stream down Satoru’s face, the blood dripping down his thighs.
This feels better, this is how it should be.
The young oni made him feel weak and made Uraume question his judgment. He can’t allow it to happen again, no matter how sweet the boy can be. He must learn his place.
Satoru cries from the pain, but what hurts more than his torn walls is the sharp pangs in his heart. He thought that Sukuna liked him, and he had been fooled by the earlier gentleness.
Seeing the brand on his abdomen, Satoru is reminded that Sukuna had taken him to be a possession. He was probably lying about wanting Satoru to be his student or his lover as well. There’s no love to be found in this cruelty.
Sukuna reaches for all four of Satoru’s limbs with each arm to hold him in place, spreading his legs and arms wide open. His body is so small atop the oni king as he’s defiled and made into a bloodied, sobbing mess.
Sukuna finds he hardly enjoys the act, especially after their tender morning, so he fucks harder to drown out the noise in his mind, to drown out the sound of Satoru’s cries.
Ugly sobs wrack Satoru's small body as he's moved up and down Sukuna's cock like a doll. He should have expected something like this from Sukuna, but the bitterness of betrayal is still hard to swallow.
Sitting behind the boy, Uraume feels forgotten as their king ruthlessly fucks the small oni in his lap. No matter how they move their hips or what tricks they try to use, Sukuna remains solely focused on trying to break Satoru.
They have never resented any one individual this much, but at least it seems like after tonight, the boy will no longer be a problem. Uraume doesn't see how Satoru can come out of this unbroken. Sukuna is truly the wisest.
Sukuna cums with a violent growl to the sound of the boy’s cries, spilling from both cocks into his two concubines. Once emptied into the boy’s abused hole, he releases his limbs to let him fall face forward.
He closes his eyes and wraps an arm around the sweat drenched child on his chest.
Satoru snivels as he's held against Sukuna's chest. He wants to be as far as he can from Sukuna, but he can't move with the heavy arm pinning him down. Sukuna is still inside him, and the warmth of his semen inside him feels awful, making his bleeding wounds burn.
“I hope you understand why I have to do this…” Sukuna mutters against the boy’s white hair. He waits until his cock starts to soften before he pulls out with one final drag of his barbs to spill his seed all over his thighs.
Uraume lifts themselves off gracefully, not even wincing as the barbs claw against their skin. They’re silent as they watch, in awe of their king.
Sukuna’s grip on Satoru stays tight, “There is just one last lesson, my boy.”
Satoru doesn't respond to Sukuna, too hurt and tired to care about what Sukuna has to say to him. He really thought that Sukuna cared at least a little about him, and the realization that he doesn't hurts more than anything else.
“Silent for once, hm?” Sukuna runs a hand down Satoru’s back, petting him gently. He sighs, and hammers in the message, “Good, you should be thinking about what you’ve done. All four of you are important to me, and each concubine is to be treated as family. I’m sure you’ve learned better than to threaten your own.”
Satoru has never had a family before, and he certainly doesn't want the likes of Uraume, Kashimo and Yorozu to be a part of his family. He hates this place and hates what Sukuna has done to him. No amount of nice words or gentle touches from Sukuna will placate him now that he knows how deceitful Sukuna is.
“Hold him down, Ura.” Sukuna lifts the boy from his chest and pushes his limp body onto Uraume. Though startled, they wrap their arms around Satoru obediently.
Sukuna still towers above as kneels before the young oni, holding his now flaccid cocks in hand.
“I heard about the cute nickname you had for me, piss king, was it?”
"What of it?" Satoru sniffles defiantly. He glares venomously at Sukuna, trying to scrape together the last shreds of his pride. He thrashes against Uraume, but he's too weakened to break out of their hold.
Sukuna chuckles darkly when the boy finally speaks. “Figured I’d live up to my name.”
Gripping himself at base, Sukuna gasps as a few droplets of hot piss fall onto the boy’s chest. He inhales sharply, before releasing a stronger stream from both cocks to drench the boy.
Satoru is frozen in shock as he’s soaked with piss, his dignity shriveling up into a husk as he's degraded. Any small hope he held that Sukuna respected him died with each splash of hot liquid on his chest. Knowing that Uraume is there watching has Satoru wanting to immolate with humiliation.
He closes his eyes and tries to pretend he's somewhere else, but he can't escape the acrid scent of Sukuna's piss. Satoru heaves in disgust and shame.
Uraume can’t help but snicker at the scene before them. Any doubts they had about the king’s resolve vanish as piss drips down from the boy’s chest and onto their thighs. Sukuna is truly a fearsome and magnificent king.
Sukuna’s eyes are half lidded as he pees on the small oni, marking him with his pungent scent.
“Never forget, you belong to me. Any insolence will be snuffed out until you learn to behave like a good little boy.”
Satoru doesn't want to be good for Sukuna anymore. He thought he had been behaving, and that Sukuna was pleased with him, so he doesn't understand why Sukuna is hurting him again. He's no longer crying, all his tears replaced with indignant anger. All Sukuna cares about is his own pleasure, and not once has he tried to make Satoru happy.
He's had enough of their arrangement. Nothing is worth the pain and humiliation Sukuna has put him through.
Sukuna shakes his cocks to release the last few drops. “Don’t give me that look, you did it to me first, brat.”
He stands up from the bed and stretches his arms out. He’s hungry, and in a way that can only be satiated by fresh meat. “I’m going out for a bit. Make sure these sheets are fresh when I return.”
Satoru lays on the bed with his tears and Sukuna's fluids drying, unmoving until Uraume kicks him out. Uraume muttered something about bathing him after they were done changing the bedding, but he no longer cares about what anyone in this shrine has to say. He bolts as soon as he's alone, running as far as his legs can take him away from Sukuna. Satoru doesn't care that he's still filthy and in pain, he's done being Sukuna's toy. He makes his way into the dense forest outside of the shrine, wishing that he'll never have to see Sukuna's stupid face ever again.
Sukuna dresses in a casual white kimono and heads towards the nearby human village at the base of the mountain. There’s a gnawing feeling in his chest, and an insatiable hunger eating away at his stomach.
Although in a humanoid form, the oni king towers above the humans in his path. They cower at the sight of him— his massive form, red eyes and horns sticking like weapons atop his pink hair. A calamity sauntering through the village, unwelcome, revered and feared. His energy is one of pure malice as he scans the crowd for a worthy meal. They bow at the sight of him, staring at their own feet in hopes of being spared.
Sukuna wanders towards a grassy field where he spots a gathering of children. From the distance, he can hear their laughter and watches as they run and play in a game of tag. He’s never heard the boy laugh like this, he realizes distantly.
As he approaches the yard, the sight of the oni causes the children to freeze where they stand, gawking at him with wide eyes. Their parents have warned them of his kind, and the name Ryoumen Sukuna lingers like a curse from their lips like a myth that’s hard to believe, even when faced with the sight of him.
In the midst of the crowd, is a young boy about 9 with blonde hair and blue eyes. Although not as spectacular as his little oni, the resemblance is close enough.
Sukuna walks straight towards him, red eyes staring down at his prey with a hungered expression and a sly smile.
“Mister…?” The boy begins to quiver under his gaze, but stands frozen, like a deer in headlights.
Sukuna wastes no time before ripping apart his throat with his claws, spraying blood on his white kimono and causing the crowd to scream and disperse in a chaotic rush. He picks up the young boy and feasts upon his flesh, skin still warm as he drinks the blood from his veins. He’s sweet, but nothing is as satisfying as his young concubine. As Sukuna eats, he imagines the way Satoru would scream as his flesh is torn apart, consumed and made one with Sukuna’s body.
Once finished, Sukuna drops the boy’s cold, frigid corpse onto the grass. He wipes off his kimono and leaves, still unsatisfied but satiated enough for now.
As he heads back to the shrine, he looks forward to feeding the boy on his lap, hoping for a new type of dessert to bring a smile onto his face, maybe even a laugh.
Satoru is cold as he wanders the forest by himself. He hadn’t had the time to grab any clothes when he made his hasty retreat, and now he’s naked and shivering, alone and filthy.
It’s not too different from how he lived on his own before he became involved with Sukuna, but it feels different this time around. He hadn’t known how loneliness felt back then, an almost tangible presence beside him whose icy tendrils are wrapped loosely around his small body.
He doesn’t want to go back, but he doesn’t like being alone. Exhaustion catching up to him, Satoru sits on the forest floor, his knees shaky. He’s fairly certain that he won’t be seeing Sukuna again. If Sukuna truly wanted him, Satoru doubts he’d have been able to leave the shrine at all. He was only useful for some cheap entertainment– he sees that now. Sukuna doesn’t respect him, and it was stupid of him to think that he did.
That’s fine. Satoru doesn’t need his respect. What he needs is to remember his original goal: to be strong enough to kill Ryoumen Sukuna. If he can kill the oni king, he’ll have all the respect he can want from everyone else. Somewhere along the way, he had allowed himself to be drawn into Sukuna’s orbit, losing himself in favor of basking in some of Sukuna’s worthless attention.
Satoru won’t be as stupid now.
The atmosphere is off in the shrine when Sukuna returns. It’s colder than usual in the long, wooden hallways and the draft leaking through the floorboards is eerie in the silence. As he passes, the servants lower their heads out of something more than reverence, but a burdensome secret. No one is brave enough to break the news to the oni king for fear of what will become of the messenger.
It’s Uraume who awaits him with their head held low, arms folded across their chest. Inside they’re feeling smug, having finally gotten rid of the brat, but still they’re wise enough to know to be cautious as Sukuna can be unpredictable.
“My lord, Satoru has disappeared.”
It takes Sukuna a moment to process, before he spits out, “And why are you telling me this, and not looking for him?”
“The servants have been looking,” they falter, “but I… wasn’t sure if you wanted him to return, my lord.”
With a calm rage, Sukuna slaps Uraume across the face sharply. How could he not want the boy to return? He belongs to him, after all.
“Useless bitch. I’ll find him myself.”
With that, Sukuna storms out of the shrine and into the forest. He will find the boy, no matter what.
Satoru wallows on the hard forest dirt for a while until there are imprints of small loose stones and fallen leaves on the backs of his thighs. He would stayed longer, but the small hairs on his body abruptly stand on edge as he feels the presence of something dangerous heading his way.
Sukuna. He's come to find him.
He's never feared Sukuna before, but this time it's different. Heart beating rapidly and his stomach plummeting to his feet, Satoru rushes to his feet. A very small part of him wants to run back to Sukuna and hope that the oni king is here because he's worried about Satoru and desires his company, but he knows better than that. Most likely, he'll be punished yet again for running if he's caught.
Not wanting to see Sukuna ever again, Satoru keeps running. There's tears building in his eyes, and he wishes that Sukuna would just leave him alone. He's had enough of being toyed with and humiliated.
The boy’s scent is strong in the forest, reeking of blood and Sukuna’s urine like a pungent perfume. He follows the scent, looking for any signs of the young oni.
Sukuna can practically taste his blood on his tongue, sweeter than any other. The only one that can satisfy the emptiness in his stomach.
He stalks towards the young oni like a predator, senses razor sharp for any sounds or sights of him. He pauses when he finds a small indent in the earth with crumpled leaves and broken twigs.
It’s still warm, and Sukuna knows he hasn’t gone far.
Satoru pumps his short legs as fast as he can, keenly aware of how Sukuna is at his tail. He cries, not because he's afraid of being hurt, but because when Sukuna finds him he will undoubtedly be enraged and intent on abusing him further. Cementing the knowledge that Sukuna holds no affection for him.
He's out of breath quickly, and though he had used all the energy he can spare to heal himself, he's still injured and bleeding from between his legs.
Sukuna spots blood on the leaves, and leans down to swipe it with his finger. The taste on his tongue is undeniably Satoru and he grins.
His legs are longer than the young oni’s, and his stamina much stronger. He’d play this game all night if he had to, knowing the boy can’t run for long.
“Satoru,” he calls. “Come back home.”
Satoru glowers when he hears Sukuna call out for him to return home. The shrine is certainly no home of his, and the concubines are not his family. He knows that he can't outrun Sukuna, but it doesn't seem like Sukuna is chasing after him. He'll probably tire of hunting Satoru eventually. After all, he doesn't really care about him.
Sukuna maintains a steady pace, following the boy’s scent as it grows stronger.
“Aren’t you hungry? There’s steak for dinner tonight, and afterwards, a whole tray of mochi.”
Satoru is hungry, and his stomach growls thinking of the food Sukuna has listed out. But not even the appeal of sweets is enough for him to forget how hurt and betrayed he is.
“Seared on the outside, but pink in the middle so that blood spills out when you cut it…” Sukuna hums as he approaches closer. “Soft mochi that melts in your mouth, chocolate, strawberry and matcha…maybe even some new flavors you haven’t tried before.” His own mouth is watering as he speaks, taunting the boy around the corner.
"Go away!" Satoru yells at the trees. He's not sure how far Sukuna is from him, but he's close enough to be goading him, and that makes Satoru uncomfortable. "I hate you!" he shouts gutturally, his tears roughing up his throat.
“Now why would I do that, when I’ve finally found you?” Sukuna turns the corner and rushes towards Satoru to grab his small wrist in his fist.
Angry tears blur Satoru's vision as he's caught. He tries to yank his arm back, but Sukuna is simply too large for him to fight off at all.
"I hate you," Satoru sniffles weakly. He hasn't hated Sukuna in some time, and his hatred is sharper than before, honed by the softness that turned out to be nothing but a lie.
The words sting like a poison in Sukuna’s veins. “I don’t care.”
He looks down at the sorry state of the boy. Dried piss on his chest making him reek like a public toilet, mixed with leaves and blood caked on his thighs. Perhaps he should take better care of his possessions, he thinks idly.
“You’re still coming back with me.”
“Just let me go!” Satoru yanks even harder away from Sukuna’s bruising grip. “Why do you even want me to come with you anyway? You don’t care about me…”
Saying that out loud has whatever fragile walls Satoru built holding back his emotions breaking. He’s ugly sobbing once again, utterly defeated.
“I won’t.” Sukuna’s grip tightens until he worries the boy’s thin bones will break. He suddenly realizes how small he really is, and how fragile. He isn’t even using his curse technique, and instead is more like a wounded baby bird sobbing at his feet.
His grip loosens and he kneels before Satoru, almost to his eye level. He wraps his arms around the child and brings him in close to his chest, caging him with all four of his arms.
Satoru’s body is quivering as he’s embraced. He tries not to enjoy being held, but this was what he wanted from Sukuna the entire time. He feels so small, and he never believed that he needs protection but he wants it now.
Sukuna won’t apologize, firmly believing he did nothing wrong. But he can show the boy that somewhere within his cold, demon heart, he does have some fondness for him. He can understand that much.
“Come home, Satoru.” He whispers as he holds him against his chest. “I can’t have you getting cold out here, soiled like this. You need a bath, a warm meal and a warm bed.”
Satoru can’t breathe properly, his chest heaving even after his crying has died down. He doesn’t like being cold and alone, so he gives Sukuna a minute nod. He wants Sukuna to keep holding him like this, and Satoru finds that he doesn’t have the energy to keep hating him.
Hoping that Sukuna won’t be throwing him aside again, Satoru agrees to being brought back home.
Sukuna’s shoulders release a tension he didn’t realize he was holding. He picks the boy up and holds him close against his chest, resting on his hip.
The sun is setting as they walk back towards the shrine, casting an orange glow over the rolling green hills. He doesn’t speak, and there’s only the sounds of leaves crunching under his feet.
Satoru should dislike being carried like a small child, but he doesn’t want Sukuna to let him go. Nuzzling his face against Sukuna’s chest, he dries his tears. It doesn’t escape him that Sukuna was the one to hurt him, but Satoru also knows that he’s the only one he wants something like this from. Which makes when Sukuna hurts him all the more painful.
Back at the shrine, the servants rush to greet Satoru, expressing their relief about his return and wanting to tend to his wounds. Sukuna shoves them away and holds Satoru closer to his chest, as if he were shielding him.
“Leave us.”
He brings them to Satoru’s bedroom and stands in the doorway. Looking down at the boy he asks, “Do you wish to be alone?”
Alone? Satoru blinks. That’s the last thing he wants. Shaking his head, Satoru curls closer against Sukuna’s body, seeking his warmth.
He wants what all children his age wants, something he’s never had— which is to be held and cuddled.
Sukuna is taken aback by the boy’s clinginess. Tenderness is foreign to him, but something about the way the boy curls into his chest has him pulling him tighter, as if he would absorb him right into his skin.
Sukuna takes his time to bathe Satoru, using a soft cloth on his wounds until he smells fresh like hydrangeas. He then dresses him in a silk yukata custom made to his thin frame.
Afterwards, Sukuna arranges a private dinner in the master suite for just the two of them. It’s candle lit, with an immaculate feast spread upon the low table, including the steaks he promised.
All it takes is some gentle attention from Sukuna away from the other concubines, and Satoru is perking up again like a wilted flower being watered. He's quiet, not sure what to say to Sukuna, but he soaks up the lavish treatment he's being offered.
He almost feels like himself again at the first bite of the steak, blood oozing out of the meat as he chews. Sitting in Sukuna's lap during a meal is better too like this, without the other concubines leering at him.
This is nice, almost peaceful as the two eat together in the flickering candle light. Sukuna takes a piece of broccoli between his chopsticks and holds it up to the boy’s lips. “Open.”
Satoru keeps his mouth closed, frowning at the offending vegetable. It smells wrong, and he looks at Sukuna pitifully.
“I thought you wanted to get strong, how can you grow without eating properly?”
Sukuna prods at his lips with the offending vegetable.
“Eat it.”
Satoru opens his mouth to protest. To say “I do eat properly.” All he needs is meat to get big and strong, and he eats plenty of that.
Sukuna takes the opportunity to shove the vegetable right into his open mouth.
Satoru gives a dismayed whine as the broccoli is pushed past his lips. It's the worst thing Sukuna has forced inside his mouth so far, and he tries his best not to eat it even though the taste has already permeated his tongue.
Sukuna laughs and holds Satoru’s jaw until he swallows. “Good boy,” he praises with a kiss on his soft lips. “Not so bad, hm?”
"It was terrible," Satoru complains sadly. The texture is rubbery, and the florets cling to the corners of his teeth. He never wants to eat anything like that again.
“Is this more to your liking?” Sukuna takes a mochi between his teeth and holds his face down towards the boy so he can grab it.
Satoru nods, not understanding what Sukuna is trying to do as he reaches for the mochi with his small fingers. He can already taste the sweetness of the mochi behind his teeth.
Sukuna bites down harder and doesn’t allow Satoru to take the mochi with his fingers. He has a little smirk as he looks down at him.
Satoru shoots him a look of betrayal, shocked that Sukuna is taunting him with his favorite treat. He lowers his hand and sticks his lip out in a dejected pout.
Sukuna leans in and presses the mochi against the boy’s pouted lips in an indirect kiss.
Opening his mouth, Satoru accepts the mochi, feeling like a baby bird being fed. He doesn’t complain as long as it means he can have the sweet.
Their lips touch as he takes the mochi from Sukuna’s mouth, the contact giving Satoru a small, tingling sensation.
Sukuna pulls back and watches the boy as he eats. He looks happier, and Sukuna wonders how to bring a smile onto his face.
Satoru bounces happily in Sukuna’s lap as he chews on the mochi, his legs swinging eagerly. Once he’s done eating, he turns towards Sukuna, hoping for another piece.
“This is all for you.” Sukuna explains as he fans his hand over the tower of colorful mochi on the table. He doesn’t enjoy sweets as much as the boy so he idly pours himself some sake and watches him.
Satoru’s mouth falls open as he takes in all the mochi, more than even he is able to eat all in one sitting. He’ll still give it his best effort, of course.
“It’s all mine?” he asks shyly, just to make sure.
“Mm.” Sukuna sips his cup and relaxes onto the zabuton. “Careful not to get yourself too sick before training tomorrow.”
Satoru smiles giddily, his eyes almost glazing over in delight. He can’t decide on which flavor he wants to try first, so he closes his eyes and grabs a piece randomly.
Sukuna is mesmerized by the smile on the boy’s face. Every expression he pulls from Satoru leaves him in awe, from his magnificent tears to his innocent smiles. Sukuna wants all of it.
“Tell me which is your favorite, my boy.” He says as he watches. “Tomorrow I’ll bring new things for you to try, too.”
Satoru’s face is scrunched up in deep contemplation as he considers the question.
“This one!” he decides after some time, handing a half-eaten mochi to Sukuna, a green one that is filled with whipped cream and edamame paste. He wants to see if Sukuna likes it as well.
“The kikufuku mochi, I’ll be sure to remember.” Sukuna opens his mouth and lays his tongue out flat for the boy to feed him.
Satoru places the half-eaten mochi on Sukuna’s tongue. As much as he likes the mochi, he wants the validation from knowing Sukuna likes it as well.
Sukuna hums as he chews, enjoying the subtle sweetness of the mochi. “Good choice, it’s almost as sweet as you are.”
"I'm not sweet..." Satoru mumbles through a mouthful of mochi. He probably tastes a little gamey, and definitely not nearly as sweet as the desserts he's become fond of.
“So sweet, I could eat you up.” Sukuna affirms and lightly bites on the boy’s neck. “A subtle sweet that’s maddening on my tongue like the finest of desserts. A delicacy only for me.”
"I don't want to be eaten," Satoru whines. And he'd rather be the one eating Sukuna than the other way around. Maybe he'll get stronger if he consumes Sukuna's flesh, absorbing some of his power. It's too bad that Sukuna is too big and old to taste good.
“I’d wait until you’re ripe…” Sukuna mouths along his neck, nipping at the tender flesh, “then consume you whole, so you’re always a part of me.”
"Not if I eat you first," Satoru retorts childishly. He squirms against Sukuna, ticklish from the nips against his neck.
“You couldn’t even swallow one of my arms. You’d be so full of me, that I’d still take over your tiny body with my own flesh.” Sukuna mumbles in a hazy state as he nips at the boy, mouthing along his perfect skin.
He remembers how he almost lost the boy today, and grips tighter against his small waist.
“Then you’d never escape me.”
"But what if you're mean to me again..." Satoru mutters quietly. He likes when Sukuna spoils him like this, but he's still worried that Sukuna will change his mind suddenly. Punish him for reasons he doesn't understand.
“That all depends on you.” Sukuna lifts his face away from the boy’s neck, but hovers close. “You wouldn’t dare leave again.” He threatens, breathing hot against his skin. “I wouldn’t let you.”
He’d rather the boy be dead than leave his grasp.
"I won't run if you're nice to me." Satoru sees no reason to. He gets to be trained by Sukuna and eat delicious food here, of course he wants to stay as long as he's not abused.
Sukuna turns to face Satoru, gazing into his blue eyes with a burning intensity. “You won’t run, no matter how you’re treated. Good behavior will be rewarded, but you will be punished for bad behavior. It’s that simple and not up for negotiation.”
"But... it's not fair when you punish me for being who I am." Satoru's face scrunches up with indignation. "I don't know what you want from me when you say good behavior."
That's not entirely true, but Satoru is trying to worm his way out of as much responsibility as possible.
“Then I will do better at teaching you how to behave.” Sukuna says with a yawn. He finishes his sake and sets the cup on the table. “It’s been a long day, must you continue fighting me?”
"I'm not trying to fight you," Satoru promises, nuzzling into Sukuna. He yawns as well after seeing Sukuna do it.
"Can you... sleep with me tonight?" Satoru asks bashfully. He doesn't want to be left alone at the moment.
Sukuna is surprised by the boy’s request. He usually prefers to sleep alone, but since the boy is so small he’d hardly take up any space. And if he’s in his arms, he’d know exactly where he is all night.
“You can stay with me if you’d like.”
Sukuna reaches over to ring a bell, which summons several servants to clear the table in his room. Though they mostly look towards the ground, they sneak glances at the small oni in Sukuna’s lap. It’s unusual, and they’re surprised by the king’s behavior. Afterwards, they whisper amongst themselves about the young child who not only dodged the king’s wraith, but got to sleep in his bed.
Once he has been given permission to stay, Satoru excitedly leaves Sukuna's lap to crawl into his bed, pulling the sheets up all the way to his chin. The bed is so big compared to him that he thinks he can drown in it easily.
As he swaddles himself in soft blankets, Satoru at last registers his exhaustion. He's had a stressful day, and all the running he's done certainly didn't help either. He glances at Sukuna, hoping that the big oni will join him in bed before he nods off. He wants to fall asleep with Sukuna's arms around him, latching onto his soft side for as long as it lasts.
Sukuna climbs into his big bed and pulls Satoru onto his chest so that he’s laying across his torso. He wraps his arms around him and sighs, sinking into the mattress with a heaviness.
“Sweet dreams, little one.”
Chapter Text
Months have passed since Satoru moved into Sukuna’s shrine. His training has progressed rapidly from sparring with the oni king and honing his innate techniques.
Sukuna watches with a sense of pride as the boy grows more confident, fearsome and entitled. Into someone so similar to himself.
Satoru spends almost every night in the king’s quarters, taking private meals and stealing most of his coveted attention.
It does not go unnoticed. Jealous, scornful eyes wait patiently for their king to return, only for him to descend further from their grasp as he’s seemingly lost in the orbit of the young oni.
“What does he even see in that boy?” Yorozu laments in private to her fellow concubine. “Are we not good enough for him anymore?”
"Maybe you're not good enough for him anymore as a mere human," Kashimo declares haughtily. "It's bound to happen that the great Sukuna will tire of lesser beings eventually."
“We shouldn’t fight amongst ourselves…”
Uraume’s eyes narrow at Kashimo’s words. The phantom feeling of Sukuna’s hand across their face still hurts, a deep shame that burns like a smoldering fire in their heart. Was it because they're human that Sukuna turned his back to them, or…
“When we all know what the real problem is.”
Fighting between concubines is normal, and a bitter rivalry has always existed between them. Healthy competition. Whatever is happening now, the shift in status quo, is far from healthy. It's unnatural.
"Yes, you're talking about that oni runt, aren't you?" Kashimo spits hatefully, eyes sparking with fury.
“Ugh, I hate him!” Yorozu declares as she roughly brushes her long, brown hair. “Did I tell you the brat stormed in while I was with the king? He sat there leering at me with those creepy eyes and had the nerve to insult me during a most intimate time.”
Uraume's eyes glint at Yorozu's words. "Was he punished, then?"
From how far back did Sukuna's favor for the kid run? For how long has the little brat trapped their king under his spell?
“Not to my knowledge. Sukuna took him for a private training session shortly afterwards.” Yorozu glances towards Kashimo when she explains, knowing how much it irritates him that Sukuna has taken a pupil under his wing.
Kashimo grits his teeth to stop himself from saying something treasonous in front of Uraume. “I still don’t understand why lord Sukuna has decided to entertain the delusions of grandeur of that weak little runt. He’s always believed that the weak deserve no generosity, so why make an exception for him of all people?”
Hearing the others share their feelings and experiences leads Uraume to feel validated in their concerns. An idea brews in their mind, what they hope is a solution to this problem and bring their king back.
Uraume leans in close to Yorozu and Kashimo, and lowers their voice before speaking. “I fear the boy has brainwashed the king, and he’s no longer thinking clearly. For his own dignity, and well being, we should help him to be free of this spell.”
"Brainwashed, you say?" Kashimo inquires. It makes sense to him— there's no other explanation for Sukuna's out of character behavior. "How do you suppose we clear our lord's mind? Magic of that nature is not my expertise, I'm afraid, and you humans don't possess any amount of innate magical talent."
“By getting rid of the source.” Uraume says flatly. They look directly at Kashimo as they speak, “Imagine if the boy were to get into an accident, or if a training were to go awry…”
"If training were to go awry..." Kashimo scoffs. The king is too gentle with the boy to hurt him, much less kill him. However...
"I can start training the boy." He grins, the sharp fangs in his mouth glistening.
A grin weaves across Uraume’s face, “That would be so kind of you Kashimo. I’m sure our lord would appreciate it.”
Since the day he tried to run, Satoru has instead been stuck to Sukuna like a stubborn barnacle, greedily sapping as much of the King of Curses' attention as he can. He can tell that under Sukuna's guidance, he has grown much stronger. From being trained everyday to eating nutritious meals, Satoru is given all the tools he needs to surpass Sukuna one day.
He has no complaints about how he's being treated except for one thing: Sukuna hasn't pleasured him once the entire time. Satoru keeps expecting it to happen when he joins Sukuna for bed, but Sukuna has so far kept his touches chaste.
Satoru has started to take matters into his own hands. He's been shown the pleasure of the flesh, and has become addicted as a consequence. At times, he'll hide himself away in his room and palm at his small prick until his body jerks with a dry orgasm. He's not sure why, but there's an inherent shamefulness to the act, and he doesn't want Sukuna to see him touch himself.
Despite their nightly rendezvous, Sukuna is unwilling to touch the boy beyond cuddling and the occasional kiss. Since he almost lost him, the boy has become too precious in his eyes. He looks at him like a porcelain doll— something to admire, but not to touch. Fragile, delicate, and pristine.
Sukuna can’t bring himself to desecrate something so beautiful, for fear of breaking him beyond repair, and losing him. There’s a hidden fear— a foreign feeling when he touches the boy, something he doesn’t understand, and doesn’t want to.
Instead, he takes out his sexual frustrations on his other concubine: roughly, violently and sparingly. Sometimes he uses his victims for a little fun before the kill.
After an evening of battle, Sukuna stands outside of Satoru’s room to retrieve him for the night. He pauses, hand on the door, when he hears heavy breathing. Sweet, little moans from inside the room fill his ears like music and make his heart race. He pauses, stockstill, and listens carefully.
Satoru is laying on his side, his hakama pushed down so he can wrap his fingers around his penis. As he's rocking into his hands, tears of frustration wet his lashes. His hands are too small, and he can't seem to get the right grip. He wants to cum, but it's hard for him to do it on his own. He almost wishes Sukuna were there to help, but he's too embarrassed to ask.
His other hand moves to his chest, rubbing over his nipple to see if that feels good as well. He whines quietly at the jolt of pleasure from his chest, his prick throbbing in his hand as he shakes with arousal.
The sounds the boy makes fills Sukuna with a primal need. He hasn’t taken him in months, but the urge still lays dormant like a fire in his gut. No one is sweeter, tighter or as needy as he is.
He stands there, barely breathing as he listens to the boy pleasure himself. Then, as carefully as he can, he slides the door open and stands there unannounced.
Satoru doesn’t notice Sukuna entering his room with his back turned to the door and his attention focused solely on his hard penis. He can feel the blood pumping in his prick, his thighs pressed tightly together as he teeters on the edge of orgasm. His fingers are rolling and pinching his nipple, trying desperately to get himself off in any way he can.
He thinks about Sukuna and moans weakly. He wants Sukuna to touch him. Sukuna seems to be so much better at making him cum.
Sukuna’s eyes are wide as he watches the boy’s arms move, the moan he makes going straight to his cock. He wishes to see, he has to see.
“Turn around,” his voice is sultry, dripping with lust. “Show me what you’re doing.”
Satoru startles at hearing Sukuna’s voice right behind him, his hands flying off his body in panic as he turns around. His face is hot with shame from being caught.
“I wasn’t doing anything!” he squeaks, hastily pulling his hakama back up.
“Really now?” Sukuna grins. He crosses two of his arms and leans against the doorway as he stares down at the boy. “Then why are you so red, why was your hakama down?”
“I… I don’t know.” Satoru can’t come up with a good lie, so he just stutters stupidly, avoiding eye contact with Sukuna. He sits up and squirms uncomfortably, his penis still hard.
“Don’t lie to me.” Red eyes are staring directly at Satoru’s crotch, able to see the small outline of his hardened prick.
Satoru almost wants to cry from humiliation. He stubbornly keeps his lips pursed, his fingers bunching up the fabric of his sheets.
“Show me.” Sukuna licks his lips, “Don’t you want to cum, Satoru?”
Satoru gives him a minute nod. He pulls down his pants far enough for his small penis to pop out, still hard but softened from embarrassment.
“There you go.” Sukuna’s breath quickens from the sight. He slides the door fully shut behind but stays leaning against it. “Don’t be shy, show me what you were doing.”
“I was touching my penis,” Satoru admits sadly with a sniffle. He fists his prick again, body shuddering from the contact. “Like this.”
“Mm.” Sukuna hums as he watches, transfixed by the way the boy’s body shudders, small prick held by an even smaller hand. “Tell me, what do you think about when you touch yourself?”
Satoru bites his lip as he strokes himself in front of Sukuna. “I don’t really think about anything,” he says. Usually, he’s too focused on the pure physicality of stimulating himself to have any thoughts in his head. Sometimes, when he’s unable to make himself cum, he does think about Sukuna, but he’s not going to confess to that.
Sukuna’s eyes lock onto Satoru’s, “I find that hard to believe.” There’s a bulge growing in his kimono, thick and hot between his thighs. He brings his fingers to his own lips and presses against them, showing their length and the sharpness of his claws. “Do you ever wish it was me?”
Satoru casts his gaze downward. “Sometimes,” he says quietly. He thinks about when Sukuna is nice and wants to make him feel good, but sometimes even the times when Sukuna is cruel and forceful will come to mind.
Sukuna shudders at the admission. “I am your first, after all.” And only.
“And when you sometimes think of me, do you imagine my hands around your prick, tongue wrapping around you as I swallow you whole? Or perhaps… you wish I was inside of you, filling you until you can’t even think, only able to focus on me and the burning pleasure inside…”
Sukuna’s words are making Satoru warm, his prick jumping in his hand.
“All of that,” Satoru whimpers. He’s tried sticking his fingers inside himself before, but he was unable to make it feel good so he gave up.
Sukuna can’t help himself as he palms at the growing erection inside his kimono. It’s the first time the boy has been so openly erotic, and the sight of him touching his little prick is too much to bear. “Do you want to see how I pleasure myself, too? What happens when I think of you…”
Satoru can already see the outline of Sukuna’s cocks against his kimono, the sight making his mouth go dry. It scares him, but not as much as it intrigues him.
“I want to see,” Satoru declares. It’s only fair that he gets to see as well.
Sukuna grins as he opens the side of his kimono to free his hardened cocks. They’re red, and angry already from watching the boy. He wraps his hands around both, opening the mouth on his palm to lick along his own lengths. “You’d taste so much better, I wish it was you under my tongue instead…” he lets himself indulge, though he has no intention of fucking the boy again until he’s older.
Satoru is mesmerized by the sight, and how much bigger Sukuna is compared to him.
“Why not?” He wants Sukuna to touch him, and he whines as he rolls his hips into his fist. It doesn’t feel as good when it’s his own fingers, and his palm doesn’t have a mouth like Sukuna’s does.
It’s been some time since Sukuna pleasured himself, never really having the need to with so many desperate bodies seeking his touch. It feels good having the boy’s eyes on him and fills him with white hot arousal. He begins jerking himself, flicking his wrist to get a good angle as he throbs in his own grasp.
“When you’re older,” is all he offers, not wanting to explain more at this moment.
Satoru’s brows are drawn upwards in a look of hurt. “That’s not fair,” he complains, stomping his foot unhappily.
He tries to pleasure himself, but it's difficult with Sukuna watching, and he’s not good at it. “Sukuna, please. I want to cum.” Satoru’s thighs fall further apart, inviting Sukuna to touch his small prick.
Sukuna’s breath hitches at the sight and pre cum beads from his swollen cock head. “Then cum.” He says, unrelenting.
"I'm trying!" Satoru squeezes his eyes together, his thighs shaking with strain. He opens them again to shoot Sukuna a pathetic look. He grips his prick tighter, lightheaded with pleasure.
The boy looks pathetic as he whines, little hand stroking clumsily over his throbbing prick. He decides to offer some advice. “Lick your fingers, and put them inside yourself. Keep going until you feel a rubbery piece of flesh just a few inches inside.”
Keeping one hand still wrapped around his penis, Satoru brings the other to his mouth so he can wet his fingers. He moans around his digits then timidly presses them against his hole, leaning back so that he can reach and exposing himself to Sukuna at the same time. Saliva makes it easier for him to push his fingers inside than the times he's tried to do it himself in the past, but it's still uncomfortable. Satoru keeps staring at Sukuna, seeking his guidance.
“Keep going.” Sukuna’s voice is labored as he pants, stroking himself to the boy’s whorish display. “You’ll know when you’ve found it, don’t you remember how it felt?”
Satoru pushes his finger further inside, his soft walls clenching tightly around it. He keeps changing the angle, growing more frustrated with each attempt until he at last brushes against his prostate.
"Sukuna!" he cries out, his eyes crossing from the jolt of pleasure.
“Good, now curl your fingers, and move them in and out.” Sukuna instructs, voice dripping with lust as he watches. It’s hard to maintain his distance, but he wants to see the boy cum from his own hands.
Curling his fingers, Satoru slowly pumps them in and out of his hole, his walls clinging to his thin digits. He jolts whenever an inward thrust presses his pads against that spot inside him, and the hand he has around his cock has loosened as this new sensation takes over his body.
Satoru only manages to thrust his fingers a few times inside himself until he's shaking with orgasm, and he cums with a throaty moan of Sukuna's name.
Sukuna moans at the sight and the sound of the boy bringing himself to orgasm. “Good boy, so pretty when you cum.”
He steps closer to Satoru. He hovers above the boy, and his heavy cocks cast a shadow over his face as he strokes himself. “Stay where you are, but open your mouth.”
Satoru keeps his mouth open obediently, staying still even though he's hit with a strong desire to lay down. His head is fuzzy with the afterglow of his orgasm, and from hearing Sukuna call him a good boy.
Sukuna fists himself over the boy, pumping hard and fast as he stares down at his wet, open mouth. He wants to push past those soft lips, to make the child gag on his length. It doesn’t take long before he’s spilling hot ropes onto the boy’s tongue, painting him in white as it drips onto his cheeks, chin and neck.
Satoru startles as Sukuna's seed lands on his face and tongue. The taste is strange, but Satoru finds himself swallowing it down faithfully. Maybe if he consumes enough of Sukuna's essence, he'll be able to steal some of his strength.
"You've made me sticky and gross," he protests, wiping at his face with his sleeve. It only seems to smear it across his skin.
Sukuna leans in to lick his own spent off Satoru’s cheek, cleaning him with a drag of his tongue. “When you’re older you can mark me like this, too.” He huffs as he tucks himself back into his kimono. “When you can finally produce semen from that cute little cock of yours.”
"When is that going to happen?" Satoru tilts his head to one side. He's not even sure if he wants to be able to produce semen. It seems messy and gross, and he wouldn't like having to clean up after each time he touches himself.
“When you go through puberty. Your body will go through changes, and you’ll grow.” Sukuna says as he cups Satoru’s face in his palm. “Once you can produce semen, you’ll be old enough to take me again. Until then, I can’t risk breaking, and losing you.”
Satoru frowns as he processes the new information. "I can't be broken," he says stubbornly, offended by how Sukuna apparently believes him to be fragile in any capacity. "When does puberty happen?"
“You ran from me. You cried in my arms like a wounded animal.” Sukuna’s hand grips tighter around Satoru’s jaw, the one he once broke in his cruelty. “It won’t happen again.”
Satoru pouts at the reminders of the times he acted like a baby and at being made to feel like a child.
“I’m not always like that.” He puffs his chest out confidently.
Sukuna presses a chaste kiss to the boy’s lips. “No, and someday you will become a fierce oni.”
Several days later, Kashimo awaits in the hallway for the young oni to pass by.
“Satoru! Long time no see.”
He places a hand on the boy’s head casually, as if sizing him up. “Too busy training with the king to hang out with your fellow concubine?”
“Who are you again?” Satoru knows that the other oni is one of Sukuna’s concubines, but he doesn’t remember his name.
Kashimo’s eyebrows furrow, but he tries to stay calm despite the indignity of being forgotten by such an insignificant being.
“I’m hurt you’ve forgotten, brother. It’s Kashimo, the god of lightning.” He boasts proudly. “Maybe if you came to dinner more often, we’d get to know each other better.”
“Kashimo.” Satoru sounds out the syllables on his tongue. “What makes you a god when your lord, Sukuna, is but a king?” He asks this genuinely, not trying to further damage Kashimo’s ego yet achieving that all the same.
“Our king may be that in name, but he’s so much more. He’s the strongest, most malevolent in nature and the only opponent to best me.” Kashimo says, tone full of admiration for Sukuna. “And as for why they call me a god, I’d rather show you.”
“I’d like to see what makes you believe you’re worthy of such a title.” Not that Satoru is expecting much from him, but he’s still curious. He hasn’t fought anyone other than Sukuna in too long, and he needs to be able to adapt his fighting style to all types of opponents.
Kashimo grins. “Then fight me, little brother. Show me what you’ve learned from the king.”
Satoru doesn’t hesitate to immediately start with a strong beam of red light, hurtling towards Kashimo at a piercing velocity. He smirks cockily at the other oni, confident in his own abilities.
“Oh ho!” Kashimo grins. The blast is surprisingly powerful from the small oni, and gives him an idea of what Sukuna might see in him. “You don’t even warm up, huh? Doesn’t matter to me, I’ll squash you regardless.”
The hairs on Kashimo’s arms rise as electricity zaps through his veins. He discharges the voltage, sending a shockwave towards Satoru.
The burst of lightning arcs towards Satoru, but it fizzles short in front of his Infinity. Dissipating the energy of the blast was no easy feat, however, and Satoru's small body hairs are singed from the tendrils that had escaped into the gaps of his defense.
"You can't even touch me," Satoru says, sticking his tongue out in provocation.
Kashimo is taken aback, he’s never seen a power like this before. He expected the fight with the boy to go easily, not to be an actual challenge. It makes it all the more satisfying to destroy the young oni.
He tests Satoru’s ability by trying to crack a punch to his jaw. His fist hovers against his skin, unable to touch. “What’s this?” Kashimo asks with genuine interest.
“This is why I’m going to be the one to defeat the King of Curses and become the next oni king.” Satoru has gotten a lot better at maintaining his Infinity thanks to Sukuna’s training. It’ll take a lot more than before for him to be worn out and unable to keep his technique up.
“Well, aren’t you confident.” Kashimo mocks. He wants to tear the cockiness away from the kid, and have him begging at his feet. He’s a god after all, and while the kid may be strong, he’s nothing in comparison.
He looks around the hallway, then back at Satoru. “Let’s go to the training hall, for a proper match.”
Satoru nods in agreement. If they keep fighting here, they’re bound to destroy something, and he doesn’t feel like being yelled at by Sukuna for misbehaving. He’s still hoping for Sukuna to touch him some time soon, and pissing him off likely won’t help him achieve that.
Once they’re in the training room, Kashimo locks the doors behind them. “Good, now we’re alone.”
He rushes the boy immediately, pummeling him with punches and kicks laced with electricity. He wonders if with persistence he can break the boy’s barrier.
Satoru frowns as he withstands against the onslaught. Each individual attack does little against his Infinity, but together they pose a potential threat. Though his hits aren’t powerful, Kashimo is fast. Faster than he is. Satoru only gets a few good attacks in among Kashimo’s countless blows.
Kashimo has a wicked grin on his face the entire time he punches uselessly against the boy’s barrier. “I see you’ve mastered your defense, but where’s your fight? This can’t be the only thing that’s got the king so entertained.” Kashimo eggs him on, “Or did you seduce him with that small body of yours like some cheap whore? Do you open your barrier for him to get between those little legs?”
Satoru doesn't understand exactly what Kashimo means, but he gets the insinuation and it inflames him.
"I'll show you fight," Satoru snarls. He's always been sensitive when his abilities are doubted, when people see how small he is and assumes he isn't capable. While he may not be as fast as Kashimo, the other oni is so close to him that it doesn't matter. He gathers as much cursed energy as he can in the palm of his hand, and an ethereal blue glow detonates between both of them, the energy rippling in the air.
Kashimo laughs and sparks fly from his skin, sticking his blue hair up in sharp angles. Satoru manages to wound him with blue, and Kashimo can’t help but appreciate the strength from the little oni. Despite his disdain for the boy, he will always admire strength above all else.
“That’s more like it!”
Kashimo takes a few steps back and squares off. With a growl, he transforms and body is coated with armor of electricity, swirling and violent. He grows bigger, taller and his body takes on a bright purplish hue once in his true oni form.
Satoru freezes, transfixed, as he witnesses Kashimo's transformation. Tapping into their oni forms is something that requires great training and concentration. Something that he hasn't been able to master, and something that he should ask Sukuna to guide him in next.
"What do you think you'll be able to do with that?" Satoru taunts, refusing to shed his arrogance.
“Eliminate you, so that our king comes back to us.” Kashimo spits, voice deeper and more primal than it was before.
With increased speed, he lunges towards the boy and tackles him to the ground.
Satoru gasps as the lightning arcing from Kashimo’s new form shreds through his technique. In a blur of flashing light, he’s abruptly pinned beneath Kashimo’s big and heavy body, rendered completely useless.
“Get off me!” he hisses, not yet comprehending that Kashimo intends to kill him.
Kashimo’s eyes are wide as he pins the boy’s arms above his head with just one hand. Satoru’s wrists are thin, like twigs, under his grasp. “You’re strong, but not strong enough to be at the side of Ryoumen Sukuna. It’s too bad the training got carried away, but I’m sure the king won’t miss his little play thing too badly.”
With a harsh push down, Kashimo feels the thin bones crack and break under his grip.
Satoru lets out a small cry as his bones shatter. He thrashes against Kashimo, but it's no use. Once he's pinned, there is little he can do to free himself even after all his training with Sukuna. He's in a position where he can't compensate for the disadvantages of his small body.
"I deserve to be by his side as much as you," he growls, biting hard into Kashimo's forearm. His tongue crackles with electricity, and the taste of burning fills his mouth.
“You think that now, but he’ll soon grow bored with you.” Kashimo spits bitterly, clearly speaking from experience. With his free hand, he starts tearing away at the boy’s clothes, burning the edges of the fabric with his electrified form. Before, Satoru would show up to dinner bruised and marked by the king, but now his skin is pristine, without a single blemish. “Or has he already?”
"Sukuna would never grow bored of me!" Satoru kicks at Kashimo with his small legs. He can't activate his technique when they're touching like this, but he still does all he can to force Kashimo off of him.
“The naivety is pretty cute. Maybe he likes the idea of desecrating something so innocent….” Kashimo thinks out loud as he strips the boy, leaving him naked beneath him on the cold, hardwood floor. He pinches Satoru’s little pink nipple between his fingers, sending a zap through the bud as he mocks him.
Shame twists in Satoru’s gut as Kashimo pinches his nipple. He’s capable of tolerating a lot of pain, but this feels too personal. His eyes grow watery with humiliation and he glares spitefully at Kashimo through damp lashes.
“You’re just jealous that Sukuna likes me more than you,” he spits.
“Shut up, brat. How dare you use his name so casually.” Kashimo cracks a punch right into Satoru’s cheek, like he’s wanted to do the entire afternoon. His face swells, and Kashimo feels pride knowing he’s finally bruised the boy.
“I wonder if he would still want you if you weren’t so pure anymore…” his hands wander down Satoru’s stomach, feeling the way he twists uselessly underneath his much larger form.
"Don't touch me!" Satoru thrashes even harder against Kashimo. The other oni's fingers feel wrong on his body, as though they don't belong there. He wasn't afraid of Kashimo hurting him, but the way he's touching Satoru does scare him. Makes him nauseous.
“You’re not even strong enough to stop me.” Kashimo mocks as his hands wrap around Satoru’s cocklet. “You haven’t even hit puberty yet, look how small this is! So pathetic.” His palm sends jolts of electricity against the boy’s penis as he laughs.
The mention of puberty wounds Satoru, a reminder of why Sukuna won’t touch him. He shrieks at the electric shock against his sensitive prick, blood rushing to the small, inflamed length.
Kashimo feels the boy harden in his grasp and begins jerking him, increasing the electric current that seeps from his grasp. “You’re enjoying this aren’t you?”
“I’m not! I hate this!” Satoru cries. It hurts so badly, like the skin of his prick is being rubbed raw. His penis is throbbing painfully in Kashimo’s electrified hand.
Kashimo releases Satoru’s shattered wrists and shoves his fingers into his mouth. “Get them nice and wet, it’s all the lube you’re gonna get.”
Satoru bites down hard without any hesitation, his sharp fangs sinking through Kashimo’s flesh as he tries to gnaw the finger off.
Kashimo rips his hand from Satoru’s mouth, shredding a piece of flesh. “You’ll regret that!” He shouts as he cracks his fist against Satoru’s jaw. “You must like it rough you little whore.” he adds with another punch, battering the kid’s face.
Satoru winces with each hit, his lips splitting apart and bleeding down his chin. His face is swelling up from the strikes, but he stubbornly refuses to show any weakness, continuing to glare bitterly at Kashimo.
Kashimo snarls at Satoru, marching his glare with glowing cyan eyes. “You’re feisty, I’ll give you that. But it only makes it more fun when you finally break.”
With one hand on his prick, Kashimo roughly thrusts two fingers into the boy’s little hole. Electricity seeps from his fingers to zap the boy’s walls as they clench around him. The meager amounts of spit act as a conductor to channel the electricity.
Body seizing up, Satoru screams shrilly from the two fingers jammed inside him so unceremoniously. His body jerks as electricity jolts him from the inside, his muscles dancing of their own will as he's forced into a painful orgasm.
"Sukuna...." he whimpers pathetically. He's terrified, and Sukuna is the only individual he can think of now, even though he has also hurt him just as much.
Kashimo feels the kid convulse underneath his hips, cock throbbing in his grasp, like an orgasm. But his hands are dry. “Did you just cum dry? Don’t tell me…-“ he chokes out a laugh, “You can’t even make semen?” He can’t help but laugh, it’s all too much.
Kashimo doesn’t stop his relentless assault, forcing the boy’s hole open. Hearing the king’s name from his lips only enrages him further.
Satoru keeps mewling Sukuna's name miserably, sobbing as his hole is torn apart. The electricity coursing through his small body makes him jerk like a fish on a hook. He can no longer tell if his muscles are spasming because of the voltage or because he's being forced to cum. It's all the same either way.
Once Kashimo feels the boy is open enough to fit his dick inside he rips his fingers out. “I’m going to enjoy splitting you open….” he murmurs as he frees his hardened cock from his hakama. It’s barbed, and throbbing as he lines up against Satoru’s hole.
Before Kashimo can move any further, an unseen slash rips across his torso, spilling blood across Satoru’s chest.
Sukuna stands there, enraged as he takes in the sight of Kashimo in his hideous true form, purple and electric hovering over a sobbing, bloodied Satoru.
Satoru has his eyes squeezed shut as he keeps whimpering Sukuna's name. He can't stop Kashimo from doing what he wants, so he tries not to see what will happen to his body. A wave of nausea makes him want to hurl when he feels Kashimo's cock press against his bleeding hole.
He waits for the inevitable, to be speared on Kashimo's cruel length, but it never happens. He's too scared to open his eyes to see what's happening, and he keeps chanting Sukuna's name under his breath like a prayer.
“My lord,” Kashimo chokes out, blood dripping from his lips as he turns to face Sukuna. “It’s not what it looks like, the boy, he…”
As he starts to tuck his cock back inside his hakama, Sukuna sends a slash to sever it clean from between his legs. The flesh falls onto the hardwood, like a bloodied worm. Kashimo shrieks and rolls off Satoru, staring with disbelief at his fallen member.
“I won’t hear any excuses, you swine.”
Upon hearing Sukuna's voice, Satoru opens his eyes fearfully. An exhale of relief calms his tense muscles when he sees Sukuna there, answering his call.
"Sukuna…." he whispers, lips still trembling. He's never been happier to see the oni king.
Sukuna glances towards Satoru for a moment, taking in the swelling on his face and the rips in his clothing.
“The god of lightning really had to go into his true form to fight you, hm? Must have really given him a hard time.”
Satoru scrambles away from Kashimo while the big oni is doubled over in pain. He's shakey as he gets up, but the moment he's on his feet he's running towards Sukuna, wanting to hide away in the folds of his kimono.
Kashimo starts to stand, enraged at the onslaught and how Sukuna is clearly choosing the boy over him. All the years he’s spent by his side, his undying loyalty, shattered by some runt.
“Stay back, Satoru.”
Sukuna warns as steam starts to rise from his pores as if he were boiling inside. His skin hardens like an exoskeleton, inhuman and red like the colors of hell.
The oni moans, in something like pleasure and agony, as his skin grows and widens, making him taller and broader with a second set of eyes on his gruesome face.
All four red eyes glare down at Kashimo, who cowers before the oni king’s true form.
“Any last words?”
”So this is how it ends? You will tarnish your legacy as the strongest being to have graced the earth for that little brat?” He scowls at the oni child, who hides deeper into Sukuna’s robes until only his nose is poking out. Pathetic.
“At least I will have the honor of dying by your hand.” The type of death that he has craved for as long as he has served the oni king.
“What would you know about legacy? If you didn’t let such petty emotions overtake you, you could have been something, Kashimo. What a disappointment.”
Sukuna speaks as he forms a ball of fire between his palms. As the flames grow hot and bright, Sukuna spreads them into a sharp arc like a blade.
“Instead, you’ll burn for trying to take what belongs to me. There will be nothing left of you, and you’ll be forgotten.”
The fiery blade cuts through the air, catching the sparks on Kashimo’s body to create an explosion. It cracks loudly as it burns brilliantly.
Satoru peeks out from Sukuna's kimono to stare at the glorious flame flickering from Sukuna's hands. The glow of the blazing inferno reflects in his eyes, flickering embers among his crystalline blue pupils.
He's never felt like he's needed protection before, and has always been too proud to accept aid from anyone. But with Sukuna, he knows what it is like to feel safe. To have someone that he can turn to and know he'll be accepted into welcoming arms.
Sukuna places a hand between Satoru’s horns, holding his face forward towards the burning oni.
“Watch carefully, Satoru.”
Kashimo wails as his skin bubbles and splits open under the flames that consume his body. It’s a slow, agonizing death as he stares at his king and the boy he chose.
Satoru's eyes are glued in fascination as Kashimo's flesh crackles and melts before him, flakes of charcoal crumbling off of his electrified body. He steps out from Sukuna's kimono to get closer, the heat of the fire warming his shivering body.
“Finish him.”
"Can I?" Satoru asks, slightly awed. He inches even closer to Kashimo's burning body.
“Yes, show me how cruel you can be, my boy.”
Sukuna intends to foster the growth of the young oni, to make a worthy opponent, a fearsome companion at his side. Is that not a legacy in itself?
Unblinking, Satoru holds his palm out in front of him, gathering cursed energy into a swirling red orb. It grows and grows until it’s larger than his head, air billowing about it in a violent current.
Releasing his technique, the entire training room rattles and Satoru’s bones shake from the force. The light nearly blinds him, but he’s still able to see the moment the red orb comes in contact with Kashimo’s blazing body, disintegrating his flesh into nothingness.
The moment is somber, frightening and beautiful. Sukuna watches quietly as his concubine disintegrates before him, face empty as the red reflects on the black of his eyes.
Once there is nothing left but a burnt scar on the wooden floor, Sukuna walks behind Satoru and places a hand on his small shoulder.
“How fearsome.”
Satoru tilts his head up to peer at Sukuna, eager for further approval. His face and body throbs and aches from what Kashimo had done to him, but the pain doesn’t matter anymore.
All that matters is Sukuna, who came to protect him when he thought no one would. Sukuna in his glorious true form, towering over him, the most beautiful shades of red.
Sukuna takes off his haori and drapes it around the boy. It drowns his much smaller form but manages to cover him decently. After all, the boy’s naked form is for his eyes only.
“Let’s get you cleaned up, it’s almost lunchtime.”
Clutching the haori wrapped around him like a blanket, Satoru follows after Sukuna. Each step hurts, the wounds inside him stinging, but he’s too frazzled to remember how to heal himself. He’s numb and floaty, and he needs Sukuna badly. In what form, he’s not sure. He just knows that he’ll take any kindness he can get from the oni king.
Sukuna notices the boy limping and pauses. “Come here,” he murmurs as he gently picks him up, cradling Satoru against his chest with the haori wrapped around him.
“No one will ever touch you like that again.” Sukuna promises as he carries the boy to his room.
“Okay,” Satoru mumbles, his cheek pressed against Sukuna’s chest. He doesn’t want Sukuna to ever let him go.
Sukuna sets Satoru down at the edge of his bed and grabs his chin between two fingers. He investigates the wounds on his face closely, wincing at how the boy’s cheeks are swollen in shades of purple and blue.
“Stay still.”
Sukuna swipes his hand over the boy’s split lip, healing it slowly as he hovers over the area. Once healed, he leans in to place a soft kiss on his lips.
“Where does it hurt the most?”
Satoru chases after the kiss, frowning lightly when Sukuna breaks away. He can’t remember what it was like to be afraid of Sukuna anymore, to resent him for hurting him.
“My face hurts,” he says with a sad sniffle. His face is swollen painfully, throbbing with each heartbeat. He’s pretty sure that his cheekbones have fractured.
Sukuna’s hand travels across the boy’s face, healing the swelling and fracturing, until the pink dusting of his cheeks and perfect pale skin is restored. “Where next?”
"My... my penis," Satoru stutters uncertainly. The idea of having someone touch him thereafter what Kashimo had done scares him, but his prick is red and swollen, raw and in pain.
Sukuna inhales sharply, rage simmering in his veins. He wishes he could kill Kashimo again, and again, in new and tortuous ways each time for touching what’s his, damaging what’s only meant for him to see. One death is too merciful.
His exhale is shuddered and forced as he looks down at Satoru’s cocklet. It’s red and swollen with dead skin peeling off the shaft like it’s been burned. It looks excruciating, an image he’s going to remember for some time.
Sukuna is silent as he cups Satoru in his palm and uses his healing technique to repair his damaged cocklet.
Satoru shrinks away at the touch to his penis, small body jolting at the burn. He does his best to stay still underneath Sukuna, holding in his tears as he's healed.
"Sukuna, he also... hurt inside me." Satoru lets his thighs fall open so Sukuna can see the extent of his injuries. This level of trust for Sukuna would have been unthinkable even a day ago.
Once Satoru’s healed enough, Sukuna retracts his hand. He stares down at the boy spread open for him, and images flash through his mind of the boy begging for his touch, crying his name as he trembles with ecstasy. It’s too much, and he backs away.
“You’ll have to heal yourself there.”
Satoru shoots Sukuna a devastated look, brows drawn together with hurt.
"Why?" He doesn't understand why Sukuna refuses to heal him, and the rejection stings more than any of the wounds Kashimo had inflicted upon him.
Sukuna doesn’t answer as he washes his hands. After a moment, he offers, “You’re more than capable of doing it yourself.”
Lips pulled in a small pout, Satoru tries to heal himself. He had hoped that Sukuna would spoil him a little more, but he has also been healed enough by the other that his cursed energy is mostly working as usual. The scrapes inside him seal themselves, but he's still left with a throbbing ache between his legs.
“There you go.” Sukuna exhales in relief. Seeing the boy with his clothes tattered, exposing his pale skin, is already tempting enough. It’s hard to keep his hands off him, but the resolve is only stronger after seeing the horrific sights of today. “Don’t give me that look.”
"What look?" Satoru mumbles, being difficult. He abruptly remembers something Kashimo had said. That Sukuna won't touch him because he's growing bored. It didn't seem true at the time, but with Sukuna still refusing to touch him, Satoru can't help but worry.
"Sukuna, do you think I'm boring?"
“What made you ask that?” Sukuna furrows his brows and looks down at Satoru.
“You won’t touch me anymore.” Satoru looks away from Sukuna, ashamed that he’s lacking in a way that he can’t control.
“Have you already forgotten what I just saved you from? That I killed one of my own to preserve your innocence?” Nevermind the fact that Sukuna has already taken it, by force, numerous times. “I have already told you why, and I don’t like repeating myself.”
"I don't want to preserve my innocence," Satoru says moodily, not fully understanding what is at stake here. There's a gnawing insecurity in his gut, that Sukuna will eventually turn him away because Satoru needs him now more than Sukuna wants him. It's unfair that Sukuna doesn't feel as attached to him as he does.
Sukuna walks towards the boy in one step of his long legs. He holds his chin in his hand and looks into his blue eyes, now clear of tears. “What is it you want, Satoru? For me to fuck you and split you open? We both know as soon as I did you’d cry and want to run away again.”
"I won't cry," Satoru says with a stubborn frown. "And you don't have to be mean when you f-fuck me." He stumbles over the new word, which he can guess the meaning of. Sukuna has been gentle once, and it felt nice.
Sukuna’s breath hitches as his resolve begins to crack. “But you’re so pretty when you cry.” He leans in to kiss the boy, desperately, hungrily, as if he wanted to consume him whole.
Satoru's lips are curved in a smile as Sukuna kisses him. It means Sukuna does still like him, and even thinks he's pretty. He thinks if Sukuna touches him gently now, it'll overwrite the slimy feeling of Kashimo's hands on his body.
Lips still locked, Sukuna reaches his arms down to swoop the boy up against his chest. He kisses him as he walks backwards towards the bedroom, inhaling his smile.
He tosses Satoru on the bed and rips off the remnants of his tattered clothes. Sukuna kisses along each cavern between his ribs, and underneath them. “I could never find you boring…” he breathes out as he mouths along Satoru’s tiny body. “Your beauty, your fearsomeness, your tears, I want them all.”
“You can have it all if I get to have all of you.” It’s audacious for Satoru to want to lay claim to Sukuna as a young oni of little renown, but it’s what he wants. He needs Sukuna to only look at him.
His legs fall open invitingly, despite the lingering soreness from his incomplete healing. Satoru has been craving Sukuna’s touch for too long, his own hands not enough to satisfy him after being broken in by Sukuna’s large body.
Sukuna crawls between Satoru’s legs and kisses his inner thighs. “I can’t give you that, but I can give you this…” he says as he drags his tongue along Satoru’s little cock. He moans at the taste, wanting to reclaim what belongs to him.
Satoru keens as Sukuna’s tongue practically envelops his cocklet. The newly healed skin is even more sensitive than usual, and his thighs shake from the intense pleasure.
Sukuna splays a hand over the brand on the boy’s womb, a burning possessiveness soaring through his veins. “I’ll make you feel better, so that all you remember is the feeling of me, how you belong to me, and only me.” He breathes against his cocklet before taking it into his mouth, flicking his tongue along the small length.
"But I want..." I want you to belong to me as well, Satoru tries to say, his words cut short by a strangled moan. He missed this kind of pleasure, being taken apart expertly by Sukuna.
"I-I'm going to cum!" he cries out embarrassingly soon. His entire body trembles underneath the larger oni.
Sukuna moans against his small length and pins Satoru down as he trembles beneath him. His cocks are painfully hard in his kimono and he ruts against the mattress for relief. He doesn’t let up, sucking on Satoru’s cocklet gluttonously, almost high from the taste.
Satoru fists the sheets as he orgasms, his small cock pulsating in Sukuna’s mouth. He wants desperately for cum to spill from his prick, and sobs when it’s just as dry as it’s always been. He’s still not enough for Sukuna.
Sukuna’s red eyes look up to watch as the boy comes undone. He’s so beautiful like this, face flushed, pink lips opening with the softest of cries. Sukuna wants to ravish him, to carve his claim within him.
He climbs up, arms shaking on either side as they cage the boy beneath him. The tears in his eyes are magnificent, causing them to sparkle like diamonds. It makes Sukuna pause, wondering how he could have possibly hurt Satoru this time.
“You said you wouldn’t cry…”
“I’m not crying,” Satoru insists stubbornly. He’ll feel stupid if he tells Sukuna about his worries of inadequacy, so he doesn’t.
“Why can’t I have you?” Sukuna owns him thanks to their pact, the brand on his abdomen, but Satoru has nothing of Sukuna’s that he can claim.
Sukuna swipes a finger to collect a tear droplet, but doesn’t argue about it. “What is it you want, that I haven’t given you already?” He asks as he stares down at him, panting. He’s given him so much, more than anyone, and somehow it’s not enough to make the boy happy.
“I want as much of you as you have of me,” Satoru declares boldly. It’s only fair, in his eyes. It’s what he deserves after being ticked and hurt by Sukuna. Or at the very least, he wants Sukuna to stop treating him like a helpless child, like he’s made of glass.
Sukuna smiles at the boy’s boldness. To want to lay a claim on the king, a demon with many lovers, some for a night, some for a lifetime. “Do you wish to mark me, so that I carry a part of you with me?” His hand pets along the brand lovingly as he asks.
“Can I?” Satoru asks hopefully. He’s not sure how he’d mark Sukuna. Maybe just bite him really hard. Tear off a small chunk of his flesh and devour it whole, taking with him a piece of the oni king that can never be returned.
Sukuna nods and flips the boy so that he’s laying across his chest. The difference in their sizes is never more apparent than when the child is on top of him, barely even the length of his massive torso.
Sukuna grabs Satoru’s hand and places it on the side of his neck. “It would be visible here. Would you like that?”
Satoru nods eagerly, nestling into Sukuna so his face is to the crook of Sukuna's neck. He opens his mouth, his small but sharp fangs popping out. With his teeth to Sukuna's neck, he waits to be given permission to bite down and make his mark.
Sukuna cups Satoru’s head and holds him in place, “Go ahead. Make sure to go deep, so it scars.”
Satoru happily sinks his teeth into Sukuna's neck, biting hard then tearing out as big of a chunk as he can. Blood drips down his maw as he chews then swallows the tough flesh. It's stringy from how muscular Sukuna is, but it's the best tasting thing Satoru has ever had.
Sukuna’s breath hitches as the boy bites into him hard, just how he wanted. He pulls him by the tuft of his hair to rip him away, and kisses his bloodied lips.
Satoru kisses him back, the taste of Sukuna's blood still on his tongue. He's smiling giddily, getting exactly what he wants from Sukuna for once.
“Are you happy now?” Sukuna asks between kisses. “Everyone will see this, everyone will know what happened today.”
"I'm happy." Satoru smiles sweetly, his head in the clouds. There has always been an uncomfortable knot in the pit of his stomach that Sukuna is only using him and never intends to respect him, but it's been completely unraveled after today.
“Good.” Sukuna kisses him once more. “Now, do you want to repay me for what I’ve done for you?” He angles his hips, pressing his swollen cocks against the boy’s naked legs.
"Okay..." Satoru hesitantly agrees, spreading his thighs apart for Sukuna. He already came so he's not as eager as he was earlier, but he still wants to prove that he's strong enough for Sukuna to fuck him.
“No, with your mouth.” Sukuna presses his head down encouragingly. “Like you were taught.”
Satoru goes with the motion until his face is level with Sukuna's cocks. They're bigger than he remembered and he gulps before laying a kiss on the shaft of the nearest one.
“You want me, right? Then show me.” Sukuna twitches underneath the boy’s kiss but keeps his hands to himself, for now.
Satoru parts his lips and closes them around the head of Sukuna’s cock. He sinks lower on Sukuna’s length until he’s on the verge of gagging, wanting to prove himself.
“Good, like that. Can you take more?” Sukuna’s voice is almost sweet as he coaches the boy into taking his impossibly large cocks into his little mouth. “Remember you can use your hands, too.”
Satoru nods as best as he can, his eyes squeezed shut as he struggles to take Sukuna even deeper. He chokes a little, his chest shuddering with discomfort. Wrapping his fingers around the base of Sukuna's cock, Satoru bobs his head in small motions, tears building beneath his eyelids.
Sukuna tilts his head back, but keeps his eyes locked on the boy as he chokes on his cock. It’s hard to stay still, but he gives Satoru the chance to show him what he’s learned, and how much he wants to please him. He gets better each time, more eager and it’s even better than forcing the boy. “You’re so good for me, my little dove. Keep going.”
Satoru makes a small squawk of indignation at the nickname. He's not a dove; doves are dumb little peaceful creatures. If he were a bird, he'd be something fierce, like an owl or a hawk. With a light glare, Satoru grips Sukuna's cock a bit harder, eyes shining with determination as he tries to ease it into his throat. He gets it a little further than before then he starts to gag, throat convulsing uncontrollably.
“Don’t give me that look, or I’ll force the rest in.” Sukuna spits out. “You’d rather do it yourself, right?”
Satoru pulls off Sukuna's dick so he can speak, his face pressed against Sukuna's length. "I want to be a hawk, not a dove," he whines.
Sukuna laughs, a little kuku. What a temperamental little thing.
“That so? Then keep going, my little hawk.” It’s mocking, but playful.
Satoru can tell that Sukuna is still teasing him, but he'll make the other oni take him seriously. He takes Sukuna's dick into his mouth again, pushing it as deep as he can all at once, the muscles of his throat shuddering as it enters.
“Fuck…” Sukuna moans as hips buckle underneath the boy. “Use your tongue, ‘Toru. Don’t stop.”
Humming in acknowledgement, Satoru licks the underside of Sukuna's thick cock. He makes sure that his hands are around what he can't take inside, squeezing lightly.
It takes just a few more of the boy’s sweet, clumsy bobs before Sukuna raises his hips to spill down his throat. He grips onto Satoru’s hair to keep him still as he cums, moaning loud and primal.
Satoru splutters as Sukuna's seed shoots down his throat, and he hurriedly tries to pull himself off. He continues to cough as tears leak from his eyes, his throat hurting from being used.
Once emptied, Sukuna’s hand pets the back of Satoru’s hair. “Come back up here. I’ll have the servants bring food to my room.”
Satoru happily crawls back up and snuggles against Sukuna's chest, his small limbs draped around Sukuna's body. He swallows the cum that remained in his mouth, still not entirely used to the taste.
“If anyone asks, I killed Kashimo.” Sukuna says suddenly. He knows if the other concubine found out that Satoru was the one to deliver the final blow, there’d be even more unrest. They’ve probably discovered his absence by now and the burn scar on the ground marking his remains.
Assuming it's a matter of pride, Satoru nods in agreement. He may have dealt the finishing blow, but he wouldn't have been able to best Kashimo on his own. Not with his current abilities.
"Will you help me learn how to use my oni form?" Satoru asks. He got to see Sukuna's true form today, and it was marvelous.
“Yes, we can make that the next phase of training.” Sukuna closes his eyes, imagining the boy’s full demon form. He hopes it’s not much bigger than he is now. He realizes he hopes Satoru never grows too large to lay on his chest like this.
Chapter Text
Uraume has their head bowed respectfully as they serve tea for Sukuna, Yorozu, and for themself. They had called for a meeting with their king, a chance to discuss what had happened. Kashimo has been missing, and Sukuna has said nothing about it, going on with their shared meals as though all is normal.
There is the pile of ash and scorch marks that Uraume had found in the training room, and for once, they have no idea how to talk to their king. This is not the Sukuna that they have known.
Sukuna blows onto his tea and studies Uraume. He knows what this meeting is about, and that these questions were inevitable.
“You’re wondering about Kashimo.” He says simply as he sips his tea.
Uraume nods while keeping their head lowered. They've never been afraid of their king, not even after seeing the cruelties he's capable of, but now there is fear trickling into their heart. Sukuna hit them for the first time, and now Kashimo...
"We're worried about him," they say carefully. "He hasn't been seen in some time now."
“That’s because he’s dead.” Sukuna explains casually. “I killed him.”
If he were a mortal, perhaps he would feel remorse for killing one of his own. However, Sukuna has always felt a distance even from his concubines. They may be the closest to him, but in the end, they’re still possessions, something that can be discarded when no longer needed.
"Yes. Of course." There's a subtle shake to Uraume's voice. They know that they mean more to Sukuna than Kashimo did, but for Sukuna to express no sorrow at all for killing Kashimo... What does that mean for them? "May I ask what he had done to deserve this punishment?"
“If you must.” Sukuna sips his tea and looks into Uraume’s red eyes. “Not only did he try to kill Satoru, he attempted to desecrate him. The only acceptable punishment for such blatant disregard for what belongs to me is death. A being like that is not worthy of being by my side.”
“A wise decision. As expected of my lord.” Uraume knows that there is no stealing Sukuna back from that boy’s clutches. The best they can hope for is for Sukuna to eventually tire of the little brat.
Sukuna nods as his eyes shift from Uraume and Yorozu. “Let this serve as a lesson.”
To say that Sukuna is the most important individual in Satoru’s life would be an understatement. His existence before the shrine is so pale in comparison to the rich experiences Sukuna has offered him. Satoru doesn’t think he can go back to the way he was.
Sukuna means so much to him, so why can’t Sukuna reciprocate even a small amount of his devotion? No matter what he does, Sukuna still won’t touch him the way he once had, neglecting Satoru like an unwanted mutt.
He’s sitting by Sukuna’s feet as the other lounges on his throne, picking at the edges of Sukuna’s kimono with a petulant frown.
Sukuna is resting with his head on his hand, and only idly notices the boy’s quietness. He places his lowest arm between his horns and asks, “Do you wish to come up here, my little hawk?”
“Okay,” Satoru mumbles. He sits up, waiting for Sukuna to pick him up. “When are you going to fuck me?” he asks without thinking. It’s been on his mind so much that it slips easily from his mouth.
“When did you become so crude?” Sukuna looks down at him with an agitated expression. He doesn’t reach down to pick the boy up.
“I’m not… crude,” Satoru pouts. It sounds like an insult. “Do you not like me any more?”
“How many times must we go over this?” Sukuna rolls his eyes and doesn’t bother answering. “Maybe you need some toys to occupy your time.”
“Toys? I’m not a child,” Satoru huffs. But he’s still curious about it. He’s never had a toy before. “What kind?”
“Yes, you are.” Sukuna rises from his throne languidly to collect a small box. He presents it to Satoru with a small smile. “A little gift for the one who thinks I don’t like him.”
Satoru eagerly accepts the box, taking off the lid. From it, he takes out a wooden object: a ball connected to a cup-shaped hilt.
“What am I supposed to do with this?” He grabs the hilt of the toy.
“I’ll demonstrate.” Sukuna takes the toy and flips the ball into the cup in one perfect flick of his wrist. “Try it.”
Satoru takes the toy back, mimicking the motion he just saw. He misses the first few times, then gets the ball to land on the third. It’s mildly amusing at best.
“If you like me, why do you still go to Uraume and the other one?” He’s too stubborn to let the issue go despite Sukuna’s clear displeasure at the topic.
“Because if I fucked you like I wanted to, you’d break.” Sukuna explains with a venomous edge to his voice. “Do you want that?”
"So you do want me." In that case, Satoru is even less able to understand Sukuna's inaction. "I don't want you to keep treating me like a child." Giving him toys and acting like he'd break from being looked at wrong.
“Do you wish to be split open?” Sukuna is growing agitated by the boy’s incessant questioning, and inability to take no for an answer. “You almost broke from taking one of my cocks, you’re incapable of taking both.”
"I won't break," Satoru states stubbornly. He can heal himself, and he's stronger than he once was. For the sake of his pride, he needs Sukuna to treat him as such.
“Perhaps you need a demonstration.” Sukuna is quiet for a few moments, seemingly in thought. “I’ll be back, play with your toy.”
He goes to find Uraume, and gives them a task which they gratefully accept.
Satoru glares at the toy as he idly messes around with it. He's able to land the ball consistently fairly quickly, and he's a little insulted that Sukuna thinks something like this would occupy him for long.
He doesn't set it down at any point, however.
After some time, the sound of footsteps and muffled cries are heard through the hall.
Sukuna returns with Uraume and a young boy, bound and gagged with ropes. His panicked eyes land onto Satoru’s blues, and although he tries to speak the words are muffled by the rope covering his mouth.
He’s about Satoru’s age and build, with light blonde hair and blue eyes.
"Are you going to eat him? Can I have some too?" Satoru stares unblinkingly at the other boy. He looks so small compared to Sukuna, like he'd be a light snack at best.
“If there’s anything left of him afterwards, sure you can have some.”
Sukuna gets straight to it and drags the captive child to his throne. He holds his face against the mess of bones with one hand, towering against his tiny frame that writhes and kicks uselessly beneath the oni. With a blank expression, he tears off his shorts to expose the pale globes of his small ass.
The boy’s cries echo through the room as he shivers underneath Sukuna, fear and dread quickly overcoming him.
“I found one that’s your size, so you can see for yourself what would happen to you if I were to take you how I want to.”
“I’m not the same,” Satoru insists. He watches in fascination as Sukuna manhandles the boy so easily, wondering if he looked the same when Sukuna forced him. Except, the kid in Sukuna’s lap looks weak, like the sight of blood alone would make him faint.
Satoru is also wickedly jealous of this nameless child being given what should be his by right.
“He’s the same size, but not as warm as you, nor even half your beauty.” Sukuna spits on his fingers and rams them into the boy’s hole harshly. The boy jolts forward, thrashing his little legs uselessly as he’s breached for the first time. “Maybe this one will cum properly, but I doubt he’ll like this enough to.”
Satoru glares at the boy hatefully. He wants to storm off and find somewhere to sulk, but he's also rooted to the spot with fascination. Eyes glued to where Sukuna's thick fingers are stuffed inside the boy's hole.
Sukuna is rough with the prep, only seeking to widen the hole for his own use, not the boy’s comfort. He scissors his fingers harshly, splitting his hole open barely enough before he’s opening the folds of his kimono. He wants this over quickly.
“Come over here Satoru, make me hard for him.”
Even while upset, Satoru finds it hard to disobey Sukuna. He climbs up and rests his face against Sukuna's lap, rubbing his cheek against Sukuna's dicks. Satoru takes both cocks into his hands curiously, interested in feeling them slowly harden.
"Like this?" he asks, batting his eyelashes cutely and knowing that Sukuna likely wants more from him.
Sukuna’s focus shifts down to Satoru. “Move your hands up and down the lengths, like you’re giving them a massage.”
Even the sight of the little oni between his legs, the way his vibrant blues eyes gaze with admiration as his small hands struggle to wrap around his girth is enough to have Sukuna’s cocks twitching with interest.
As he scissors his fingers inside the poor, sobbing child, he speaks in a low voice, “Do you remember when we first met, my boy?”
Satoru begins to stroke Sukuna's cocks. They feel so different when they harden, and he can practically feel the blood pumping against his hand.
"I remember," Satoru says. How can he forget? "But even then, I wasn't as pathetic as him." What does this human child have that he doesn't, that Sukuna is willing to use him instead of Satoru?
“You weren’t, and it’s why I spared your life.” Sukuna explains. “This one won’t be so lucky, and you’ll see first hand why I can’t subject you to this.”
He hardens easily in the boy’s clumsy hands, looking forward to the tight heat of the child before him. He’s not as beautiful as Satoru, but he will do it for the sake of the lesson.
“Now step aside, and watch carefully.”
With a displeased whine, Satoru sits back down. He hates this nameless human child with all his being, and he hopes Sukuna breaks him easily. The point that Sukuna is trying to make escapes him entirely when all he can think of is his jealous rage.
With a grunt, Sukuna forces the tip of one cock head into the screaming child. Even with the gag, the sound is shrill, wet and desperate. Like a dying animal.
“You screamed like this, too.” He murmurs before roughly thrusting his first cock all the way to the hilt.
Without mercy, Sukuna pulls his hips back, shredding the boy’s dry walls and spilling blood onto the white skulls decorating his throne. The small body writhes in agony as Sukuna begins his relentless assault, tearing him apart underneath his massive form.
“Is this really what you want?”
"You don't have to be as rough with me..." Satoru mutters. Shouldn't he be special enough for Sukuna to treat differently. But he still winces as he watches how forceful Sukuna is with the child, a shiver running down his spine as he recalls what it was like to have been in that position. His shrill screams as he was the one being torn apart.
The display he is being forced to watch is brutal, and it makes Satoru doubt himself. Sukuna wouldn't do that to him, would he? This isn't what he wants from Sukuna.
“Even if I was softer, the pressure on your body…” Sukuna murmurs in response to Satoru. Despite the boy’s screams, his focus is entirely on his little oni.
He doesn’t finish the sentence, and decides to show instead. With a violent drag of his barbs, Sukuna pulls out entirely. He fists both cocks in his hand, pressing them together before forcing them into the child’s tight, bleeding hole.
There’s a piercing wail, before the body underneath him goes pale and limp. Catatonic as he’s fucked nearly to death by the overwhelming size and girth of the oni king.
"I'd be different," Satoru says without too much confidence. He looks away, unable to admit that he would, in all likelihood, be unable to withstand such punishment. "Do you expect me to just wait until I'm an adult?" And wouldn't Sukuna grow bored of him if that were to happen?
Sukuna fucks harshly and violently into the unresponsive body, seeking his own release. He finds he wants this lesson to be over with, finding little pleasure in the useless child unable to even put up a fight. It’s no more interesting than fucking a doll now that the boy is unable to scream any longer.
His body surges with the need for Satoru, and it’s the only thing keeping him hard. He thinks of filling him with all of his lengths, how Satoru might be able to take it. But is it worth it? Would he risk losing the boy?
The thought makes Sukuna cums with a low moan, still mostly unsatisfied. He glares at the bloody mess he made, noticing how the child’s body has grown cold and stiff. Pathetic.
Afterwards, Sukuna turns to look at Satoru and his heart burns in his chest. His voice is broken as he realizes the answer, “And if you weren’t different, and died like this? I can’t risk it, I can’t risk losing you.”
Satoru obstinately refuses to say anything, head turned away from Sukuna. The stench of blood permeates the air, and usually that would make him hungry, but Satoru discovers that he’s lost his appetite.
He still can’t see why Sukuna refuses to touch him. He’s far from fragile, and he’s too fraught with jealousy to acknowledge that Sukuna cares enough about him to not want him to die.
He runs off before Sukuna can say anything else to him, heading straight for his room.
Sukuna wipes himself clean on the boy’s tattered clothes and leaves the corpse for his servants to dispose of.
He sighs when he realizes Satoru has run off. He hopes the boy understood the lesson, the display of truth in his cruelty. How irreplaceable he’s become to him now.
Sukuna grabs the toy from the ground and brings it to Satoru’s room as a hopeful peace offering.
Satoru slams the door shut to his room and sits with his back propped against the door. He almost wants to cry, but that would be letting Sukuna win. Sukuna, who would apparently touch anyone else except for him. It's unfair that even now, he won't recognize Satoru's strength.
The sound of the door slamming echoes down the hall, agitating Sukuna further. He stomps towards Satoru’s room and spits outside the boy’s door, “Is there no end to your tantrums?”
"No! Go away!" Satoru shouts through the door. Sukuna is the last person he wants to see right now, his pride too wounded to properly acknowledge the other.
“Insolent brat.” Sukuna growls, “Maybe I should just fuck you like that kid, until you’re quiet and cold beneath me. It would save me a lot of headache.”
It seems nothing will get to the boy, no matter how many times Sukuna explains, or how many lives he takes for him. Nothing is ever good enough.
"Maybe you should," Satoru yells stubbornly. He has his arms crossed in front of his chest. Apparently, he's still not good enough for Sukuna, and Sukuna would rather fuck a useless, weak human than him. It's not just the boy from today. He still goes to Uraume and Yorozu first, like Satoru is an afterthought to him.
“You really do have a death wish.” Sukuna sighs and grips the wooden kendama tool in his fist.
“Fine then. Come to my chamber tonight. Prove how strong you are.”
"Really?" Satoru perks up at the offer. He's not used to getting what he wants from Sukuna, and this fight was far from easy.
The nameless child felt like an appetizer, making Sukuna more hungry for the final course. “Yes, but I won’t tolerate any complaints, nor will I stop no matter how hard you beg. You know what the risk is and you’re choosing this yourself.”
"I won't complain," Satoru scoffs. He's not a little kid. "You're not lying to me, are you? You really do want me tonight?" he asks hopefully.
“I always want you.” Sukuna says before sauntering off to clean the blood of his kimono.
It's hard for Satoru to believe that when Sukuna has been so resistant to his advances, but maybe he'll be proven wrong tonight.
Satoru is a ball of nerves the rest of the day, waiting for nightfall, bouncing in his seat as he eats dinner in Sukuna's lap. He eats hastily, barely tasting his food from how fast he scarfs everything down.
“Will you come to my room tonight, my lord?” Yorozu asks with a hopeful smile over dinner. She’s careful not to spare a glance at Satoru, keeping her brown eyes locked solely on Sukuna.
“Not tonight.” Sukuna answers as he pours sake for him and Satoru. He hands the cup to the boy, encouraging him to drink.
Yorozu pouts as she watches the two of them, so engrossed in the other like she hardly exists.
Satoru accepts the cup, his eyes squeezed shut as he downs the harsh liquid. It stings as it trickles down his throat, but it doesn't appear that he'll be offered anything else to drink for dinner.
"Should I expect to prepare to service you tonight, then?" Uraume asks. They had just attended to Sukuna the night before, and not entirely recovered from that, but if duty calls, they will answer.
“No need.” Sukuna wraps an arm around Satoru possessively. He doesn’t care to explain himself, but he’s sure the others can figure it out.
He drinks his sake leisurely, enjoying the silky taste that runs smoothly down his throat.
"Oh. I see." Any belief that Uraume has that they still hold favor over the boy crumbles. The only solace they've had is that Sukuna has been choosing to bed them instead of Satoru, but now they don't even have that advantage.
After dinner, Sukuna carries the boy back to his room. He feels so small in his arms as he clings to his body with some much trust and neediness. He places Satoru onto the bed and stands before him. “Do you really want this?”
"Yes." Satoru nods, ignoring the trickle of doubt creeping into his mind. He's abruptly reminded of what happened to the human boy, how they are the same size and how easily the human broke in Sukuna's hands.
He's not like that, however. Satoru is stronger. Different.
“Even if it costs you your young life?” Sukuna asks as he kisses along his neck and shoulders as he peels off his outer layers.
"It won't," Satoru declares, dispelling whatever fears were lingering within him. His breath stutters from the kisses Sukuna lays on his neck. "But... you won't be mean, will you?"
Sukuna undresses the boy with reverence, kissing every inch of skin that’s slowly exposed under his hands. He tilts Satoru’s face to press their lips together, as if to reassure he’ll be gentle. As much as he can be.
Satoru kisses back eagerly, his small body laid bare before the king. His thighs part invitingly for Sukuna and his body burns with a lustful heat.
Sukuna slides his tongue into the boy’s open mouth, tasting him, as his fingers trace along his inner thighs. He presses Satoru down onto the bed as he leans partially over him, feeling his body with each of his four arms. “You make it impossible to resist you…” Sukuna breathes into the kiss as the tongue on his palm releases to lick the boy’s small nipple.
"Why do you wish to resist me?" Satoru mumbles between kisses. Sukuna seems like the kind of individual who takes what he pleases without caring for the consequences. What was wrong with Satoru that he felt this urge to fight his nature?
“I don’t want you to end up like that boy, dead on my throne.” Sukuna kisses Satoru's neck, worshiping his skin. His hands grip at his thin hips, feeling his rib cage, down to his hip bones. “You belong to me, and I don’t want to lose you.”
Satoru has a small smile as Sukuna feels up his body. At last, he understands that Sukuna is feeling protective of him. Though he finds Sukuna's reason for neglecting him to still be silly. His skin prickles with small goosebumps from Sukuna's fingers brushing against him.
Sukuna’s hand snakes between the boy’s legs to wrap his small prick in his palm, a second hand wrapping from behind to lick at his entrance. “What changed with you? When did you become so needy of my touch?”
"No I'm not," Satoru denies with a hot flush. His hips buck into Sukuna's hand, his mouth falling open in soft gasps as pleasure makes his toes curl. Sukuna's touch feels so different from his own, better in every way. It's all he can think of at times.
“You’re not, hm?” Sukuna’s hand stills, tongues retracting into his palms. “Then you wouldn’t mind if I stopped.”
Satoru shoots Sukuna a look of betrayal, eyebrows drawn tight in hurt. "I didn't say that! And you shouldn't break your promises."
“Then what are you saying?” Sukuna asks with a playful lilt to his voice. His hand stays palmed over the boy’s throbbing cocklet, unmoving. “Tell me.”
"I... want you to touch me," Satoru says carefully. A compromise. He tries to roll into Sukuna's hand to relieve some of the aching arousal of his penis.
“Like this?” Sukuna asks as the mouth on his palm opens so that his tongue can circle around Satoru’s prick once more. “Is this what you need?”
Satoru's mouth goes slack as the tongue swirls around the head of his dick. He nods, unable to form any words between his heavy breaths.
As much as Sukuna wants to hear the boy beg, he also loves when he is unable to speak, so easily lost in pleasure as he melts under him. He slides his hand between the boy’s slit, then circles his rim with the tongue, breaching inside to begin stretching him out. “Have you been touching yourself here, wishing it was me?”
"I— I have," Satoru admits between gasps. Being opened with Sukuna's fingers for the first time is still a strange sensation, but one that he has grown to like, even before it starts to be truly pleasurable. He touches himself like that sometimes, but his fingers are frustratingly short and slender.
Sukuna grins at the confession, “So needy.” He changes his tongue for his fingers, wanting to feel the boy’s walls clench around him as he’s stretched. He reaches deep inside for Satoru’s prostate, having memorized its location.
Satoru's entire body jolts as Sukuna presses against his prostate. "I'm not needy," he insists, even as pleasure wracks his body. "I-I just want..." He moans brokenly as his muscles clench uselessly against Sukuna's fingers.
“Want what?” Sukuna presses as he curls his fingers to massage the boy’s prostate, feeling how easily he stretches for him as he walls spasm with pleasure. He takes Satoru’s little cock into the mouth on his palm, circling his tongue around him as his fingers move.
Whining, Satoru's lips fall open in the shape of Sukuna's name. The pressure inside him and around his cock have become too much, and he cums as drool leaks from his mouth. It feels different than how it usually does in a way he can't describe.
Sukuna pauses when he tastes it, the unmistakable, salty taste of semen on his tongue. It’s a pathetic load, but it still makes Sukuna marvel. He brings his palm to Satoru’s lips, “Open, and taste yourself my perfect boy.”
Satoru has yet to kiss any of Sukuna's constructed mouths, and he's curious to know if it feels any different. There are no lips on Sukuna's palm, and his skin presses against Satoru's open mouth, the tongue sliding in. Satoru frowns at the faint saltiness that he tastes, and he looks to Sukuna with widened eyes for answers.
Sukuna chuckles at the frown, “Doesn’t taste as good as mine, hm?” He brings his hand to his own lips, to taste. “I quite like the taste of your cum, and I want you making more of it for me.”
"I want to... for you." Satoru's thoughts are still hazy, but he can tell that he's pleased Sukuna, and it makes him smile dopily. He holds his arms out, wanting to kiss Sukuna's real mouth this time.
Sukuna lets himself be lured in to kiss the boy, swapping the taste of him between their tongues. He reaches to grab the lube from his bedside table, and lathers himself generously.
“Hold onto me.” He instructs as he presses up to Satoru’s little hole, only partially stretched for his imposing length.
Satoru's fingers cling onto Sukuna's bicep as Sukuna's cock is lined up against his hole. It feels so thick, bigger than he remembered it to be. He knows that Sukuna promised to be careful with him, but he can't help but remember all the times that he hadn't.
With a low moan, Sukuna pushes past the boy’s rim to press inside. It feels like coming home as Satoru’s walls clench around him, tighter than any other.
Satoru bites his lip hard as he endures the initial breach. He's being split apart so wide, and tears prick his eyes from discomfort. His muscles tense, resisting the intrusion.
“Stay with me, little one. You’re finally getting what you want.” Sukuna leans in to kiss Satoru as presses deeper despite the resistance. It’s impossibly tight, but he’s determined to fill the boy with both of his cocks tonight.
Satoru inhales deeply, strengthened by Sukuna's encouragement. This is what he wanted, to prove to Sukuna that he's capable. He hopes that it will feel better than it will hurt.
Sukuna can feel the boy relax around him, and he takes the opportunity to press all the way inside. His breath shudders and he looks down at Satoru with half lidded eyes. “Heal yourself, I know you can.” He advises as he slowly starts to pull out, dragging the barbs across Satoru’s hole.
Satoru yelps when Sukuna forces the rest of his cock inside. He doesn't have to look to know that it's pushing against his abdomen, making his flesh swell from the sheer size. The painful pull of the barbs against his insides makes Satoru's head fall to the side, his face pinched together in pain. Overwhelmed by discomfort and pain, he can't remember how to heal himself.
Sukuna is attentive and mindful of Satoru’s reactions, every yelp and flinch. He can feel the warm blood pooling around his shaft and he pauses his movements. “I said heal yourself. Do it, or we’re done here.”
He’s already killed one child today, and he doesn’t want to kill another. Especially not this one.
Satoru glowers, feeling like he's been reprimanded. The brief pause is what he needs, however, and he's able to gather enough concentration to close his wounds.
"It's just going to tear open again," he pouts, no longer in pain. He's not sure if he can keep healing himself the entire time.
“Then heal it again.” Sukuna starts thrusting slowly, aiming for his prostate to ease the pain. “Remember that you wanted this, you knew what would happen.”
"Right there!" Satoru cries out when Sukuna succeeds. His mind scrambles to heal his wounds as pleasure numbs his thoughts. His prick throbs with hardness between his legs, untouched.
Sukuna thrusts hard and deep, pulling out slowly so that the barbs don’t shred Satoru’s walls too badly. There’s still some blood, but the boy’s ability to heal allows Sukuna to keep going. It’s more sensual than he usually is, and he treats the boy more like something to be worshiped than to be used as he kisses along his face.
“Satoru…” he murmurs as he looks down at him a bit too fondly.
Doubts that Satoru had held about Sukuna wanting him wash away from the look of adoration in Sukuna’s eyes. Satoru tilts his head so that Sukuna’s next kiss lands on his lips. Even with how gentle Sukuna is being, his insides hurt from his injuries, but Satoru finds that he doesn’t mind the pain so much anymore. He reaches for his dick, feeling that he is close to cumming again.
“Let me help you.” Sukuna purrs as his hand wraps around Satoru’s prick. He folds the boy’s legs towards his chest so he can push in deeper, obscuring him in the shadow of torso as he overtakes his small body.
“It feels so g-good,” Satoru chokes out as he’s fucked even deeper. “Sukuna, I—“
Satoru cums before he’s able to finish his warning, a small trickle of mostly clear seed dribbles from his prick.
Sukuna presses their lips together hungrily, sliding his tongue into the boy’s mouth to drink in the sweet little moans he makes. He feels overwhelmed with warmth in his chest, and an affection he’s never known before as he admires the small amount of semen the boy made for him.
His second cock slides underneath Satoru, hard and needy as he begins jerking himself off between his cheeks. “Are you ready to prove how strong you really are?
Loose-limbed and sated, Satoru nods lazily. Blood dribbles from between his legs from when he wasn't able to heal himself quickly enough. He still isn't aware of Sukuna's intentions.
"Are you going to cum inside me?" Satoru asks. It's been so long since Sukuna has done that that he can't remember if he likes it or not. But it would mean that he makes Sukuna feel good too, that Sukuna likes him.
“I’ll fill you with both, so that you’re dripping with my seed.” Sukuna promises as he pulls out slowly. He holds both cocks together tightly and lathers them with lube until they’re wet and sticky in his palm.
“If you can survive this, you’ll have earned my respect and admiration.” He proclaims as he presses the massive girth of both cock heads against Satoru’s small, bloodied hole. “Take a deep breath, little hawk.”
Satoru freezes, his body breaking into a cold sweat. He's overconfident, but not enough to think he's capable of this.
"Wait, Sukuna! I don't know if..." He looks pleadingly at Sukuna, hoping that it will make the other change his mind. "I'm too small for that," he tries.
Sukuna kisses his teeth in agitation. “After months of begging and throwing yourself at me you’re going to back down now?” He teases his cocks along Satoru’s rim, applying a slight pressure without breaching inside. “You said you were different, stronger. Was it a lie?”
Satoru startles at the pressure to his hole. He can't even imagine how they'd fit inside. "But, this isn't what I agreed to."
His brow furrows. Satoru doesn't like being called a liar, and his desire to prove himself is being weighed against his self-preservation. "I am strong..."
“I don’t recall agreeing to anything. All I know is for months you threw yourself at me, claiming you were strong enough to take me, only to whine and quit when I finally offered what you wanted.” Sukuna sits up, holding his angry cocks in hand. “Do I need to call Uraume instead?”
"Wait! Don't get Uraume, please." Satoru raises his head in alarm. The last thing he wants is for Sukuna to go to his other concubines. Choosing them over Satoru again. "Am I not enough for you?"
Sukuna pauses and looks down at the child beneath him. He looks the most beautiful like this, with white hair fanned over the sheets, damp with sweat against his flushed face. But it’s his eyes that startle Sukuna the most with their impossible beauty, as they stare up at him like Sukuna is the only thing that matters.
“Prove to me that you are.”
Satoru nods. “If I do, does that mean I’ll be the only one you’ll go to?”
His hole is already sore from being fucked, and his skin is tacky with his own fluids. Satoru feels gross, but he hopes that Sukuna doesn’t mind.
Sukuna blinks in surprise. It’s not the first time one of his concubines have expressed the desire to be his only, but he never expected it from the arrogant child who promised to slay him with own hands. The one who claimed to hate him, and ran away. The one he tricked and forced into being his concubine in the first place.
“Is that really what you want?” He begins to jerk his cocks together as he talks, “Do you realize how insatiable I am, how often I’d take you….”
"Then I'll just get stronger," Satoru declares. He knows he's capable of it, even if he isn't at that point right now. "And you will help me."
He tries not to look at Sukuna's cocks, knowing that it would make his bravery falter. It's worth it, if he can claim Sukuna for himself. He needs Sukuna to acknowledge him as his equal, more important than the weak concubines Sukuna surrounds himself with.
“You will.” Sukuna moves his palm over Satoru’s hole to heal the damage he’s already caused. “By my side, you’ll be the strongest, second only to me.”
He leans over the boy once more, cocks leaking with anticipation as he lines up between Satoru’s legs. He moves his hand to begin pushing both cockheads inside. It’s impossibly tight, and Sukuna hisses as the boy’s walls reject the intrusion at first.
Satoru's hands are clenched into tight fists as Sukuna tries to bully his way inside. It's too much, Sukuna is trying to split him apart. Whatever he thought, he can't do this. He wants to tell Sukuna to stop, but the only sound he's able to make is a pained whine.
His body isn't meant to be used like this, at least not yet. He's capable of enduring pain, but there's no changing that Sukuna is simply too big compared to him.
“You’re so good for me.” Sukuna praises as he moves his hand between Satoru’s cheeks, trying to heal his splitting rim as it’s forced open to accommodate him. He places another hand onto Satoru’s cocklet, massaging lightly as he continues bullying his cocks inside the boy.
The hand on Satoru's cock makes him whine in discomfort, the flesh too sensitive to be touched. He's soft from pain and overstimulation. Satoru throws his arm over his eyes, regretting his decision to allow Sukuna to do this to him. It's too late to back out now, and he can only moan torturously as he's split open.
When Sukuna finally bottoms out inside the boy, he moans, low and primal like a beast. He’s so tight, barely able to take his cocks as he’s stretched wide around him. He removes Satoru’s hand and kisses all over his face, murmuring endless praise about how strong he is, how good he feels.
How he’s more special than anyone else.
Sukuna keeps his hand close to his rim, healing the damage as he starts to pull out, dragging the barbs on the boy’s overstretched walls. Blood spills down the sheets and onto his thighs despite his attempts to mitigate the damage.
Nothing about this is pleasurable for Satoru, but he grits his teeth and endures it. Through his blurred vision, he catches a glimpse of Sukuna's face with an expression that makes his chest twinge. No one else has looked at him like that before. "Do I feel g-good?" Satoru stutters, eager for praise. Anything to make the pain worthwhile.
“The best, Satoru.” Sukuna affirms as he starts to fuck into the boy earnestly, ripping him apart with every thrust. “You’re perfect for me.” It’s so tight it’s heavenly, making Sukuna shudder as he’s gripped within the boy’s tiny body.
The best.
Those words echo in Satoru's head as Sukuna uses his body, bringing him the most exquisite and terrible pain. It's not the title he had sought- the strongest- but it's just as good coming from Sukuna's lips.
Sukuna continues praising the boy, decorating him with kisses and small bites as he seeks release. Each thrust has resistance as the boy struggles to take him. He’s moved by the effort, knowing it’s no easy feat to take him like this, especially from someone so small. Someone he thought was fragile.
“I’ll take care of you after this, just stay with me a little longer. You’re doing so well, my perfect boy.”
Sukuna starts fucking rougher, using Satoru in the way he needs. His moans are deep and guttural, echoing throughout the room as skin collides.
As pain overwhelms Satoru, the last tethers of his consciousness latch onto Sukuna. The weight of him, as oppressive as it is familiar. The warmth of Sukuna's body, a blanket of heat that encompasses Satoru. Above all, what he feels is searing pain, but he expected this. Sukuna is pain and pain is Sukuna. Satoru knows to pay for his place by Sukuna's side with his blood.
Satoru blinks tears from his eyes, but his vision won't clear. He wants Sukuna to be done with his body soon, but he also wants Sukuna to never stop using him, to always want him. Need him as much as Satoru does.
Sukuna can’t look away from the tears that well beautifully in the boy’s eyes. They’re staring right at him, with something that looks like admiration, almost like love.
The sight sends Sukuna over the edge. He presses as deep as he can into Satoru and cums with a moan of his name. *Satoru.* It sounds more like a proclamation of love as it’s uttered.
A small whimper of discomfort squeezes out of Satoru's lungs as Sukuna fills him with seed. He's nearly delirious with pain, his sight going in and out of focus. Despite how worn thin he feels, Satoru tugs at Sukuna's forearm, needing him to be closer.
“Stay with me, my love.” Sukuna coos as he gently drags his cocks out from the boy, spilling blood and cum all over the sheets. He’s quick to heal the damage with his palm, trying to repair Satoru’s ripped walls. “You did so well, much better than that boy earlier. You’re strong, Satoru.”
Dazed, Satoru swallows down the thick globs of saliva that have pooled in his mouth. "Of course I was much better," he slurs. The lower half of his body is numb, and the weakness he feels contradicts the confidence of his words.
Sukuna smirks, happy to see the boy is not only cognizant, but still as smug as ever. He leans in to kiss the child and a warmth floods through his body. He places a hand over his forehead to check his temperature, and places a soft kiss on his lips. “I shouldn’t have doubted you.”
Satoru makes a soft noise of content as he's kissed. He's tired, but he's content in knowing that he has secured his claim on Sukuna. A place by his side. Satoru nuzzles his cheek against Sukuna's, like a cat marking someone with their scent. His small horns graze against the side of Sukuna's head.
Sukuna rolls onto his back and pulls Satoru across his chest. He holds him with one arm, and gently pets along his back with the other. “How do you feel, is there anything you need?”
"I need..." Satoru slurs against Sukuna's chest, eyes drooping closed. He needs to be Sukuna's only concubine, but now doesn't seem like the right time to make his intentions known. Instead, he sticks to Sukuna like a stubborn barnacle anchored to a sea turtle's shell.
“Tell me little one. Anything you ask, it’s yours.” Sukuna assures sweetly. Right now he feels especially gracious as he relaxes into the bed with the small oni on his chest.
"Will you stay here tonight?" Satoru asks as his mind turns through several ideas quietly. There's no point in asking to be Sukuna's most important person. He won't have it as a consolation prize, unearned.
“I was going to anyway.” Sukuna hums at the simple request. “I’ll have breakfast brought to your room in the morning as well, any requests?”
"Mochi?" Satoru seizes the opportunity to have more of his favorite food. He smiles sweetly at Sukuna as he imagines ways to be rid of the other, bothersome concubines. Meaningless individuals who don't deserve to waste Sukuna's time. Nor his.
Sukuna scoffs at the request but doesn’t decline. He kisses the boy’s head as he drifts to sleep with Satoru cradled in his arms.
