Katsuki slowly slinked into his chambers after a long day of running hell. The door made barely a sound behind him as he sauntered over to his room, passing his private dining area, sauna, and library along the way. Much to his delight, he found his human spread out on his bed like a personal buffet. A five star meal just for him to enjoy.
Deku's wearing nothing but a simple, thigh length, dark green nightgown. It was carefully hand crafted from the finest silks in the kingdom. Katsuki actually sent some of his underlings to the human world to search for it, knowing that they made it best. He wanted the gown to be as soft as a feather and as gentle as a mother’s loving touch against his human's delicate skin. Plus, the deep verdant green contrasted gorgeously with the boy's pale skin, making his freckles pop and his hair look like a glowing halo.
Said nightgown was now inching slowly up Deku's peachy thigh as he relaxed on the black satin sheets, happily reading some adventure book. He was resting comfortably on his belly, head laid on his arms and legs slightly spread, shadows covering up what Katsuki wanted to see most; that perfect pussy. The book he took from Katsuki’s personal library was propped up on a fluffy pillow, old pages touched delicately by small, nimble fingers.
Katsuki's mouth started to water at the sight, drool dripping between his sharp teeth as it pooled under his tongue. The skin of Deku's milky freckled thighs looked so deliciously soft, and the way the simple straps of the gown fell off the boy's shoulder was absolutely sinful. The light coming through the window was making him glow, warmth radiating from the ethereal being and warming Katsuki up more than hell itself could.
Katsuki’s gaze was smoldering as he licked his lips with a forked tongue, like a predator ready to devour its prey. And boy, was Katsuki ready to devour the delicious meal in front of him. Closing his jaw with a loud snap, alerting Deku of his presence, he stalked forward, belt buckle clinking as it fell to the red carpeted floor.
With one glance at Katsuki's face, red eyes blown wide with feral lust and drool running in rivers down his chin, Deku hurriedly put his book away. Not wanting to lose his place once Katsuki got a hold of him, after all, he was just getting to the interesting part. But he had duties to fulfill, so his book needed to wait.
Izuku was pretty much Katsuki's over-glorified cockwarmer, there to pleasure his king at the snap of a finger. And he loved it. He loved being used like a toy. Loved sitting around all day looking pretty in the finest clothes, and eating the most delicious foods, only for Katsuki to take one look at him and ravage the poor boy. The tray of food would be shoved aside, hand picked fruits and homemade cheese falling forgotten on the floor by their feet as clawed hands tore apart the rare silks covering the king’s prize. Deku loved the feeling of that large ribbed cock knotting him so good it felt like his mind was falling apart. And the amount of cum Katsuki produced was heavenly. It filled him up to the point his belly bulged and Deku swore he could taste it on the back of his tongue.
He especially loved it when, after an exceptionally rough fuck, Katsuki would pamper him and call him sweet pet names while gently scrubbing him down. Large hands capable of so much destruction and bloodshed would rub light circles over fresh bruises, applying soothing ointments as loving words put back together Deku’s scattered mind. But now wasn't the time for sweet pet names.
Now, Deku was going to get fucked, and enjoy every second of it. Katsuki had him pinned down, one hand holding his wrist above his head, careful not to cut the delicate skin with his talons, while the other kneaded Deku’s peachy squishy ass.
The human was still on his belly, but now his hips were raised like a good bitch and the nightgown was left in tatters on the floor. Oh well, Katsuki would get him a new one, after he fucked Izuku till he couldn’t walk.
Katsuki's cock was so big as it rubbed tantalizingly between freckled thighs, stimulating the sensitive skin just enough that Deku could feel teasing sparks of pleasure in his tummy, but not hard enough to really get him off. Like this, Izuku could really see how deep the massive dick would go, tip rubbing precum past his belly button. He could already picture it rearranging his guts as Katsuki pounded him into the bed, making him scream as his insides were molded once more to the shape of the demon King’s cock.
With that fantasy in mind, hole starting to gush sweet sweet arousal, Deku wiggled his hips to entice the king into finally fucking him. He needed it! But Katsuki was in the mood to tease. And he always got what he wanted. So instead of slamming in like the little angel was begging him to do, he continued to gently rut against the plush thighs surrounding his cock.
Deku had a cute little freckle on his lower belly that Katsuki was aiming for. Every calculated roll of his hips pushed the burning head of his throbbing cock into it. And every time he pulled back, it was left shiny and dripping with copious amounts of pre that sent shivers through his human’s skin. It was so cute how Deku jolted with every brush against it. His belly was so sensitive, and the rubbing of his thighs did nothing to help the teasing pleasure.
Katsuki decided to pick up speed, cock starting to burn with need, but not enough to make him give in. He needed to let all the tension of the day seep out of him before he can really start to fuck his boy. And he had a rough day. No one wanted to fucking listen. The henchmen he sent out to collect fine wines and silk for Deku fucked up and brought the ONE wine Deku didn’t like. He thought he made the orders very clear but those incompetent fuckers still messed up, and one of them even got caught. Un-fucking-belivable.
“K-Kacchannnn…” Deku whimpered in pleasure, snapping Katsuki out of his thoughts. Dropping his head from where it was staring into nothingness, he noticed that in his rageful musings he squeezed Deku harder, claws digging into soft skin. Pinkish hand shaped marks decorated Deku’s hips, already starting to bruise wonderfully. They looked beautiful. And Deku, being the good slut that he is, just flaunted his hips for more, pussy already making a mess of the sheets. Katsuki was definitely going to have to replace them. But that was a problem for later. Right now, he was going to eat his meal.
A hand slipped to Deku’s thigh, thumb digging into the sensitive sticky skin that had just been rubbed raw. The mewl that Deku let out was pure sin and it made Katsuki grind his teeth in an attempt to stop himself from mounting the boy right then and there. With quick movements, Katsuki manhandled Deku until he was upside down on his lap, face pressed into Katsuki’s thigh and pussy right next to Katsuki’s mouth. Katsuki watched as Deku’s swollen chubby clit twitched with every breath against it, warm air from Katsuki’s mouth teasing it in the most frustrating but mind numbing way.
“P-pleaseee Kacchan! I need you to f-fuck me!! Not this.. I want your coAHHNNN!!” begged Deku, pleas turning into a warbled moan as Katsuki shoved his tongue into the gushing cunt in front of him. Deku’s back bowed as much as it could in this position as he let out another pleasured scream. Katsuki’s tongue was so long and thick. It was stretching his teeny pussy apart, preparing it for what was to come. The saliva coating it mixed with the delicious ambrosia Deku let out, creating a smooth slide that had the boy’s thighs trembling from where they were wrapped around Katsuki’s head. The pleasure of his sensitive walls being rubbed so roughly was making his eyes roll back as his cute little kitten tongue hung out of his mouth, lines of sticky drool coating his chin. His soft chubby tits squished against the pulsing muscles of Katsuki’s thighs, cherry nipples getting crushed oh so good.
Deku could feel the tingles from his chest mixing with the burning heat of his throbbing cunt. His tight hole twitched pathetically around the intrusion as Katsuki pushed in deeper, drinking up as much of the slick as he could get. The final straw was when Katsuki stretched out his long forked tongue, the tip of it tickling his guts while the rest thrusted against Deku’s weak spots.
With a trembling moan of Katsuki’s name, Deku cums hard. His thighs tensed and shook uncontrollably in Katsuki’s hold, toes curling and shoulders flexing in an attempt to deal with the all-consuming pleasure. His pussy was throbbing and burning as squirts of slick were forced out, warm tongue not stopping for a moment.
Deku went limp as the boiling pleasure died down, leaving him with a content and warm feeling in his guts as his head buzzed pleasantly from being held upside down for some time. With softer hands than before, Katsuki peeled the limp human off of him, licking his lips to capture any extra slick as he repositioned Deku in his lap. Now Deku was upright, face red and covered in all sorts of liquid from a mix of pleasure, embarrassment, and cumming his brains out. He giggled up at the demon, small hands resting on burning skin as he collapsed forward in an exhausted heap.
Thankfully, Katsuki finally burned off some of his rage. With a sharp toothed grin, eyes ruby burning dangerously, he leaned down and whispered in Deku’s ear. “Get ready, shitty human. I’m going to fucking destroy you.”
Katsuki could feel Deku shiver against his skin, bright green eyes darkening as lust took over him. Fuck. Izuku was perfect. The most perfect insatiable slut.
Shoving Deku down with a hand on his burning chest, Katsuki flipped him over again, admiring his glistening pussy and swollen sticky clit. What a beautiful sight, Katsuki thought idly as he pried Deku’s lips apart with a single finger, exposing his twitching, gaping hole. He watched hungrily as slick began to bead up, trickling down Deku’s flushed taint and mixing with the leftover saliva. It was so wet. A perfect soaked hole for his dick.
Done with admiring his handiwork, Katsuki lined himself up, slapping his dick down a few times for good measure, chuckling deeply at Deku’s surprised squeaks. He pushed in, sighing as the tip of his scalding cock popped in Deku’s needy pussy. The slick made the slide in so soft, Deku’s entrance opening up for him like he was meant to be there. The throbbing tight heat on his cock was too much, so without much warning, Katsuki slammed in, a pleasured growl slipping past his lips.
Fuck, it felt so good! They were definitely going to be here for a while.
***
It had already been over an hour and Katsuki was nowhere near done, hips thrusting brutally as his muscles clenched in fizzy pleasure. The fiery magic he possessed gave him an unfair amount of stamina in all fields. Fighting, working, flying, and fucking. He could go all night if Deku's body could handle it.
The human definitely wanted to go all night, but as much as Katsuki loved his tight little pussy and sweet cries as he was fucked through another burning orgasm, he didn't want to break his toy. But right now, Deku was fine.
Sure, his legs were trembling as sweet, sweet pleasure so strong it was almost painful coursed through his veins. All while being an incoherent drooling mess, clutching the sheets desperately and slurring out pleas for more through hoarse moans as his body fell limp in Katsuki's hold, allowing the demon to manhandle him like a doll. And he was Katsuki's cute little sex doll. A warm, tight hole for him to stick his dick in whenever he got the urge.
Deku trembled as another mind bending orgasm ripped through him, back arching beautifully as sweat trickled down his porcelain skin, now covered in hickeys and love bites. "K-K-Kacchannnn!!! P-pleasee, haah... it feels shooo good!! AHnn!! M-more! More!!"
Deku weakly wiggled his hips, back arching to entice the blond into fucking him harder. Katsuki really did find the perfect little cockslut.
But Katsuki was getting a little bored. Not with his human, god no. He could never be bored with Deku. He just wanted to spice things up. And Deku was too out of it to really register what was happening.
Katsuki flipped the squealing boy around, his back hitting the pillows with a soft thump as burning red eyes met tear filled emeralds. Katsuki always found Izuku so pretty. Prettier and more heavenly than any angel out there. And his cries sounded like music when Katsuki pushed his legs up by his ears, bending him in half like a kid playing with a toy as he used his full weight to fuck into him. Each powered thrust had his cock bruising that sweet pussy, making Deku shake and beg for more. He was definitely not going to be able to walk tomorrow.
There was so much slick and leftover drool coating Deku's chubby pussy that lewd squelches echoed throughout the room with every powerful thrust. Katsuki's hips were covered in it, and every time he pulled back, fat twitching cockhead forcing Deku's poor pussy open, strands of the creamy gooey sweetness connected them. Katsuki tore his eyes away from Deku's throbbing cunt to glance at the boy's face. His cheeks were blotchy and red, both from the overwhelming pleasure of being speared on a thick demon cock, and the fact that he was almost upside-down, pussy practically dripping onto his drooling mouth and plush lips from how far Katsuki was bending him. His trembling freckled legs framed his tear stained cheeks perfectly.
Fuck.
Katsuki felt like he could burst just from the sight alone. It was so lewd.
And It was only for him. No one could even dream of his Izuku like this without facing his wrath. Katsuki got rougher as his orgasm approached, thrusts turning brutal and hands gripping hard enough to bruise. Pleasure was stirring in the pit of his belly as heat slowly overwhelmed his nerves, vision fading to blinding white. He grabbed Deku's calves, pushing him down further, and with one final thrust, he came.
Deku squealed when Katsuki's knot popped, slick squirting out of his spasming pussy in steaming jets, dripping onto his face and splattering Katsuki's toned abs. And Katsuki wasn't faring any better, deep growls of pleasure rumbling through his core. He distantly registered that Deku was squirting, but he was too focused on the rush of endorphins to really care. He much preferred focusing on the way his sweet little nerd trembled with every pump of cum into his cunt and the taste of his soft, spit soaked lips as he bent down to kiss them.
Fucking hell. He loved his human.
