Chapter 1: Genya/Tanjirou/Sanemi

 

Today's work, is based on Genya/Tanjiro/Sanemi. 
On the image above, I'll be creating my fanfiction, based on this here image.  - Libidine, Your author-chan.

---

Tanjirou always managed to catch himself staring at Sanemi's thick scars, that raced up his chest, across his arms in thick lines that made Tanjirou want to stroke them with a fervent but gentle hand, showing him no more pain was to come. The way his low voice seemed to flow into his ears, around his form, as if he were embracing him- if only he was. But it  would never change what the man had done to his little sister. 

 

But Tanjirou loved seeing the light of the sun catch on Genya's eyes, the dark purple of them so disarmingly attractive, his dark hair thick and Tanjirou had imagined it to be so deadly soft. But he could only wish those eyes would look at him with affection.

 

When those secrets- those desires- that were tucked away were brought to light, Tanjirou wanted nothing more than to burrow into the silken sheets that helped him fall asleep well into the dawn. Curling up, ashamed of his feelings for both brothers. 

And then,

Tanjirou's arms start to tremble as he continues to hold himself up, shivering as Genya holds his hips, and without any oil, his bare thighs feel raw as the older fucks between them, his insides are spasming, and the more he struggles, the deeper, and harder each thrust gets, until Tanjirou wants to slam his face into the soft sheets below him. Was this really only his tongue? 

 

“Please, please, no more-” he hiccups wetly as his tears fall, plopping onto the pillows, looking back at the demon-slayer before his arms finally give out beneath him weak, and over used, he doesn't know how many times Genya had hade him cum, he can’t handle any more. Then, he’s flipped over, his legs being spread open before Genya and Sanemi's eyes.

 

“You shouldn’t have said yes to us, Tanjirou. Now look at you-” Sanemi bites a particularly tender spot on his bruised shoulder, and Tanjirou cries out, his hands trying to stop him, weakly clawing at his uniform as Sanemi licks down his neck, holding his face between his hands, nibbling gently as he went, admiring the way the younger boys flesh caved in through his teeth, leaving a glistening trail of saliva along his clavicle. "-all vulnerable, like a bitch in heat"

 

Tanjirou is loosely holding onto Genya's hair having given up on pushing Sanemi away. As Sanemi leaves an imprint of his sharp teeth on Tanjirou's neck, he whimpers weakly as his nerves flare, tense, and then wholly in awe at how Genya flattens his tongue on his opening, licking up and around in rough licks, digging his fingers into Tanjirou's soft ass, his nails ripping into the flesh. 

 

“Oh- oh my god-” Tanjirou's eyes squeeze shut as tears make their way down his face, trembling in their grasp but Genya doesn’t stop, even snickering between his legs, stopping him from trying to close them due to sheer embarrassment as Sanemi licks away his tears with a smug grin, he forgot how big of assholes they could be. 

 

“Tanjirou, Say my name-" 

 

Giving a short glance down at Genya who raises an eyebrow, "-our names." Sanemi drags his fingers down to Tanjirou's nipples, his nails raking over the hardening buds, tweaking them harshly and pulling the buds up hard as Tanjirou arches his back off the dark sheets with a sharp cry of pain, and sound makes Sanemi groan, Why hadn’t he fucked this brat sooner?

 

"There's only us.” His hips are lifted up before one of Genya's hands holds his thigh tightly, the bruises on his skin screaming in protest, And Tanjirou was left feeling how Genya's fingers pressed into his entrance, Finally . “G-Genya, wait- ah--!?”

 

Genya's fingers, slick with gel are scissoring into Tanjirou, feeling the tightness of his hole as he groaned, part of him thinking that fingering Tanjirou wasn’t even possible. But he was trying to hold back from just fucking him, the last thing he wanted was to hurt him, but the cries Tanjirou made, were more than enough encouragement. To hell with prepping- but then again. Tanjirou was so cute when he moaned, with his ruby-red glassy eyes and kiss-swollen lips, and slightly puffy nipples, his cock dripping pre-cum as it twitched against his toned stomach-.

There was no-way he was leaving this room un-touched. 

 

“Everything of yours is ours, and you can't fight us, Brat. So-” Sanemi leans in, his low, deep voice winding through Tanjirou's flushed ears, and it leaves Tanjirou shaking .
“-cum for us, bitch.”

 

Tanjirou shudders in their arms, whining out in what was left of his voice, holding onto Sanemi's arms as his walls clenched down tight around Genya's fingers, as they continue to press deep into him, rubbing on that spot that made white spots flash before Tanjirou's dazed eyes, and hsi legs quiver all over again.

 

Tanjirou could only feel the split second of warning, that tingle down his spine before Genya pushed inside of him, and Tanjirou can't breathe properly, his breath stuttering as he fumbles around, sliding his hand into Sanemi's as he squeezed, Hard . Feeling their breathing all sync as Genya waited for him to adjust to the sheer size of him, even with lube it was much too tight for both of them, Genya shuddered, and it took his jaw clenched shut, desperately to stop him from rutting himself inside of his Tanjirou. 

 

Genya felt like his cock was going to split in two with how tightly Tanjirou was gripping him, he couldn't even slide out to try again, he could only wait for Tanjirou to acclimate and whilst he did so, he discreetly slicked what wasn't able to enter Tanjirou with more lube, the faint scent of citrus hitting his nose as he slowly started to press in, and when Tanjirou lets out a choked, "A-ah?!"

Genya knows he's pressed exactly where he needed to for Tanjirou to loosen up. 

 

Sanemi's tongue slides against his, muffling Tanjirou's moans as he gets used to the stretch of Genya's cock moving in and out of his hole thickly, tightly. And Genya moves back before slamming in and picking up the pace the friction alone was undoubtedly going to leave bruises but Sanemi couldn’t care, Instead he takes his cock, and he presses it To Tanjirou’s open, and whining mouth, pressing inside with a groan, the gargle Tanjiro gives off is, unnecessarily satisfying. 

 

Tanjirou flailed around for a second, getting fucked and deep throating a cock took some getting used to, even with all the electricity trying to fry his brain, going numb, so free of thoughts, only focused on, the thickness inside of him. But it’s when he feels Sanemi's girth move deeper into his throat, Tanjirou could feel warm hands giving soothing pets on his chest, purring as he relaxed, making it much easier to swallow Sanemi’s cock. 

 

He was alright, he could do this. He just had to try. He breathes in through his nose and takes his length in with all the bravery he could muster,

 

 And It took a lot of bravery.

 

Tears trickle down his face, into his ears as Tanjirou tries to keep still as Sanemi roughly uses his mouth, and his jaw is so sore he feels as if it’s going to lock into place soon. With a,
"T-Tanjirou, I'm-"

Tanjirou blinks as Sanemi's hand holds onto his hair with a tight grip and he can feel the ache in his jaw persist as he swallows hard, managing to suck as Sanemi pulls out, giving a wet kiss on his lips in thanks, it was a taste he was sure, he’d never froget. 

 

Tanjirou's can still taste the bitterness from Sanemi's cum but as his tongue delves into his mouth he just stops thinking. It felt so good it left him shaking once again, how Sanemi leaned down to frame his face in his hands, and with every jolt that Tanjirou could feel from his hips moving against Genya's movements, he could feel his mind blank out as Genya fucks into him dangerously hard, and Tanjirou can only grasp the sheets in his hands as he feels his cock sliding against the fabric with every slam of Genya's hips against his own, Everything had gotten warm,and he can feel, he can feel the precome inside of him, sloshing around with each rough, pleasing movement. Tanjirou wanted all of Genya’s cum, all inside the deepest parts of him . 

 

Genya's hands curling into the dip of his waist, feeling the sweat on his back and with every, loud, obscene squelch of his cock sliding back into Tanjirou's heat and then He knew they didn’t call him the sun pillar for nothin g. He chases his own high as he leans over Tanjirou, pressing kisses down his spine as he feels himself reaching the peak, that knot untangling, and leaving him to savagley keen himself into Tanjirou’s body, like a new found disregard for the mewls , and shivers the smaller boy was giving him.

 

With a shudder, Genya wraps his arms around Tanjirou as he presses hilt deep into the velvet like vice grip, that held steadfast onto his cock even as he tried to slide out with every push of his hips into Tanjirou, as he slow fucks him, molding Tanjirou's entrence to take the shape of his cock, his cum eventually leaking out and trickling down Tanjirou's thighs as if showing exactly who owned him. And his eyes seem transfixed on the obscene look before him. 

 

Tanjirou's cock lay spent, having gone limp and boneless as he rubbed his face into Sanemi's hand, the black sheets of Sanemi’s beed room,  covered in their cum as he tried to focus on his shallow breathing and not the dizzying scent of cum and sweat mingling in the air as Genya pulls out, leaving him feeling so empty , which was strange considering that should have felt the most normal, but he knew he was never going to feel that way again after tonight's endeavors.  

 

But with Tanjirou basking in the afterglow of his orgasm, Sanemi grunted, and wasted no time shoving his fingers into Tanjirou's spent hole, Genya's cum acting as lube as he fingered him with two, then three fingers that made Tanjirou squirm against Genya already so, so dizy he was sure he was going to pass out any second now,  leaving Tanjiro to let out cries.

"Ah- it hasn't been- hnngh?!" 

Sanemi curled his fingers up and dragged out Genya's cum in leisurely strokes, making sure to glide over Tanjirou's prostate each time. He'd so desperately wanted to be his first, so, what was wrong with some friendly , brotherly competition?

 

Tanjirou holds onto Sanemi's thighs but the moans he let out weren't going ignored they couldn’t with how low, and full of arousal they were, his hands nearly sliding off and Sanemi's muscles bunched as he lifted Tanjirou up, still facing him, before pressing the head of his cock onto Tanjirou's hole, already feeling the burning heat, from the outside.

 

Tanjirou shivered in his grasp nearly blacking out in response to feeling Genya suck dark hickies onto his neck that would turn purple in the morning and without warning, Sanemi slammed up into him, feeling Tanjirou clamp down onto his cock, having sunk down onto it entirely in one go, but it was still so suffocatingly tigh t. 

 

Tanjirou lets out a breathless gasp, the air in his lungs having been punched out of him with the rough action, to hell with concentrated breathing, he couldn't breathe at all , staring mindlessly at the deep scars that seemed to swim before his eyes as he hung his arms over Sanemi's wide shoulders, pressing his face against Sanemi's his breath warm, and shaking, and his eyes grow wide, his body stiffening up at the feeling of Genya moving up against him, he tries to speak but at first, nothing but a mewl comes from his lips.

 

Sanemi pauses in his harsh thrusts, ones that added to the bruises on his hips,  as Genya starts to press up against Sanemi's cock and into Tanjirou, and the boy rasps out the words he can hardly form.

 

"Wai-? G-Gen-!?" startled, Tanjirou reverted back to his usual way of addressing Genya and with a thinly veiled pout at the slip and use of his nickname, Genya's eyebrows furrowed together in concentration as he started to slide in next to Sanemi's cock, his jaw clenching thickly.

 

"Y-you can't possibly fit-! Sanemi's already- you can't! I mean, I can't! It's impossible, there's just no way!" Tanjirou's protests are heard, but nearly ignored.

 

Genya stops moving immediately, his face showing a distressed expression at how flushed and scared Tanjirou looked, even that side of him was such a turn-on. Even though he couldn't look down at where they were all connected, Genya knew Tanjirou could feel them both, and a thump of his heart in his chest betrays his selfishness to continue onward, not that he planned to have stopped either way.

 

Why should he wait when he knew Tanjirou would love how it felt in the end ? No- he had to hold out for him- he should do that for Tanjirou, precious, lovable Tanjirou who trusted him, trusted them with his oh so compliantly pliable, and sinful body that took in their cocks like he was born for them and them alone, but the temptation only grew .

 

Sanemi's voice rumbles in his chest, lips twitching into something that resembled a calming smile only, it terrified him,
"Relax. It doesn't hurt when you relax, see?"
How much his voice reminded him of the burn of alcohol in his throat, he would never tell him how it felt as if he were choking him until he felt lightheaded- then letting go with a deep satisfaction from the bittersweetness and a new mark on his scarred skin.

 

"Tanjirou, everything is okay. We're here. You can, just breathe in." Genya's voice was beautifully elegant and surprising, yet like a blade... if it were a smell that he could recall, it would be the scent of dark chocolate upon the tongue, the bitter rough edges, the smooth, elegant finish that curled into warmth in his stomach. 

 

Tanjirou could barely remember how he got through the heavy, burning sensation that assaulted him down below but he does, and he's being moved up and down, sinking down on their large cocks like he was made for it, and he could see how his stomach bulged every time he came down on their lengths, but- he didn't..he didn't dislike how it felt at all.

 

It only takes a couple tries before he's feeling the prickle of sheer pleasure dancing across the small of his back and inside of him, and when Sanemi's dick hits his prostate straight on as he pushed in again, Tanjirou can't hold back a small wail as he clenches down on the both of them, scraping his nails down in dark red marks on Genya's shoulders, and it’s the groan that Genya swallows that makes Tanjirou shake .

 

With barely a wince, Genya leaned in, his eyelashes fanning across his cheekbones as he sucks Tanjirou's bottom lip into his mouth before kissing him with his hand at his neck, gripping feverishly.

 

Sanemi gradually lowered them onto the bed, Tanjirou's legs hooking over Genya's shoulders for dear life as he yelped as the new position made their cocks slide even deeper into him, more than he thought was even possible . It’s then that he feels, something , prodding at what has to be his internal organs.

 

With a shallow thrust to test him, Sanemi jerks upwards, holding down Tanjirou by his grasp on his hip bones, and Tanjirou falls against Sanemi's chest as he shook in their arms at the pressure of both inside him, he was sure any minute now he’d be ripped in two.

 

Tanjirou lets out a strangled gasp, not getting enough air as he feels his nipples being pinched hard and bringing them to hardness as if he were standing in the cold, freezing. The pleasure assaulted him with each sensation, feeling their cocks rub against his cum slicked insides, feeling impossibly full as his own rubs between his stomach and Genya's, and he hadn’t realized the mewls, and whines that left his bitten, swollen lips. 

 

The skin on skin contact made all the difference, the heated warmth was unlike the cool sheets, and he squinted through the tears that made his vision blurry as he feels them speeding up, pounding into him as he grasped they were close, and his whole body arched in anticipation, he wanted to be filled. Filled so badly.

 

Genya bit down onto Tanjirou's nipple, twisting the other between his fingers as he plowed into Tanjirou with a relentless pace, He knew he wasn’t going to walk the next day, or maybe evr again, matching Sanemi's timing as they shot their cum deep inside of Tanjirou, and he felt the warmth heat up his stomach and he came untouched, moaning, and writhing, desperately as he felt them spurt into him as they fucked him slowly, alternating as they arched, not to pull out even after they were done. 

 

They're murmuring lilting words of praise into his ears that make him blush all the way up to his ears and up his neck even as he gradually loses consciousness and Sanemi brushes back Tanjirou's burgundy hair, Genya pressing kisses onto his temples and eyelids as they flutter shut, not noticing the widening, fevered smiles that never seem to waver as his hands fall to his sides, his face pressing against the sheets as he falls asleep, He’d filled, and so sore, bloody and bitten he can’t stay awake, let alone even his breathing.

 

Red marks littered his skin, his neck and chest covered in bite marks, fingerprints leaving behind dark imprints on his inner thighs, hips, and waist, a living, breathing work of art by their own hands, and the two looked at Tanjirou with fondness, that couldn't be mistaken for anything else other than that one emotion. 

 

Genya's scent was like the hours before rain would start pouring, filling in with a treacherous fire, calm with nary a ripple in the lake that stood alone, yet like electricity that crackled dangerously in the air as the storm drew ever closer .

 

Sanemi smelled like the forest at night, the time when the monsters bobbed around for prey, and of evergreen trees that never died even in the throes of towering flames that brought ashen rain, like death , like pain .

 

Kamado Tanjirou smelled of adoration. Of a cool spring day in which flowers chose to bloom, of delicious fruit that popped on the tongue with a burst of sweetness, of undying trust and loyalty that never seemed to subside even with all the pain he could go through. Perfect. He smelt, and was , so perfect.

 

"Mine." A voice like Twisted Iron, and rage outspoke.

 

"Mine." A voice like thunder traveling through the clouds with lightning following its path.

 

"Ours." Voices that sounded like they would never let go of who has come into their embrace, and they weren't.

 

Poor Kamado Tanjirou. He should never have taken their hands, when they reached out with their beautiful smiles and seductive promises of wonder, and love; that masked their true intentions. And to think it all began, Because He and Shinobu began to get closer. 

 

Now, he would never be able to leave their sides. Not for all eternity, even after they died, they would have their Tanjirou. 

 

They would make sure to keep him locked away from prying eyes and dangerous whispers of the outside world, Tanjirou only needed them to survive, and whatever it took, they would do it all for him. That Butterfly bitch, as Sanemi called Shinobu, was sent on a suicide mission he had faked out, now, he could relax, and stay with his Precious younger brother, and his new, lover.

Chapter 2: Shinobu/Tanjirou, Pegging/Femdom.

Summary:

Endurance training wasn't what tanjirou expected it to be.
or,
Shinobu pegs Tanjirou.

All I have to say is, Rip Tanjirou's ass. -- Libidine, Author-Chan.

---

“You’re squeezing me very tight, Tanjirou,” Shinobu whispers, her soft and elegant smile is still plastered over her face; only the intense smell coming from her screamed in how close her resolve was to breaking.

 

The older squeezes Tanjirou’s ass in between her hands, silently admiring the plush. She gently massages the red flesh, spreading his ass open so she can watch the way his entrance just 𝘧𝘭𝘶𝘵𝘵𝘦𝘳 around her thick purple strap. Shinobu struggles to keep the pace Tanjirou’s set, the burgundy-haired boy rocking back onto her strap-on, his hips rolling with any, any relief he can get from his Hashira. There's not a single sign of fatigue on Tanjirou despite the fact that he’s already orgasmed more times than the older woman could even keep count of.

 

“C-Can’t you fuck me any harder?” Tanjirou whines, his eyes are full of thick, wet tears. Damp and leaking with the Mascara she had applied to him only a little earlier.

 

Shinobu clicks her tongue, pulling back right away; Tanjirou was shaken, his body left feeling so, empty .

 

Tanjirou glances back, his pretty, blissed, and lust-clouded eyes widening just in time for Shinobu to spank him hard enough that she’s sure that anyone within ten meters would have easily heard the slap, including the others in the medical room. Her palm 𝘵𝘪𝘯𝘨𝘭𝘦𝘴 pleasantly, smacking his ass had always come with a few, consequences. It’s not long before Shinobu watches Tanjirou’s ass thrust back towards her, no missing the wail that leaves her precious Tsuguko’s lips.

 

“T-that hurts…!”

 

Shinobu giggles, reaching forward to touch Tanjirou’s limp, and angry red, spurting cock, smearing the leftover cum all over his stomach. Her voice dips down, laced with nothing but mockery as she says, “did it really? You wouldn’t have cum if it hurts.”

Shinobu was an even bigger bully when she was in bed, her soft expression, so, so gone.

 

“T-that’s because…!”

 

Shinobu doesn’t give him enough time to come up with an explanation, as she lands another hit on the left side of his ass, hitting him hard enough that it sent him falling forward onto the mattress, his legs trembling, and leaving another one of those sweet-sounding wails to leave his lips.

 

“W-what are you—”

 

“Ah, ah, Ah, I din’t say you could speak, Tanjirou” Shinobu chirps, in a voice so high and innocent, that if it wasn’t for the nine inches of rubber inside of him, there would be no way it even sounded like they were having sex. He doesn’t get any more time to think as Shinobu is already shoving him back into the mattress, her nails digging half-moons into his neck, and all over again, Tanjirou is shivering .

 

Tanjirou whimpers into the pillow below him, thrusting his ass into the air, whining as if scared , yet he made no real attempt to escape from her hold. The most exciting part was, Shinobu knew he could escape. Never once had he tried. 

 

“Please know your place as my, 𝘴𝘭𝘶𝘵. Tanjirou” Shinobu presses her thumb into his quivering hole; feeling Tanjirou clench down immediately, already sucking it inside the deepest part of him.
“You’ve been getting awfully mouthy lately.”

 

Tanjirou lets out an apology, his words muffled by the pillows; Shinobu watches the redness start to creep down his shoulders, and she hums in satisfaction. She readjusts herself, hand around her dark purple strap, rubbing the tip of the rubber against his winking entrance, watching as Tanjirou’s hole tried to coax her back inside.

 

The older chuckles, one hand now petting the quivering Tsuguko’s thigh.
“ Oh my , did you enjoy getting called a slut? ”

 

Tanjirou whimpers, shaking his hips so desperately in response. Shinobu chuckles, slapping both thick globes of his ass at once, and continues to slap the soft flesh, before she thneaded, and groped at the reddening flesh. Tanjirou moans, silently begging and pleading for Shinobu to please just fuck him , using his hips to try, so, so hard to get more of what he wanted inside of him. The Hashira teasingly starts grinding her hips up, the tip of her strap-on slid between his asscheeks, holding the tip of herself against his pleading body.

 

“Do you want it? Want me to wreck your pretty little hole?”

 

“Y-Yes, yes,” Tanjirou chants out, but his mind is so hazy and so far gone, what had Shinobu made him drink this time?

 

Shinobu grins, running her hands over his body, she could feel just how hot he was; burning entirely from their session, yet she careful ran her fingers over every scar, she was going to show him, just how much he meant to her.

 

“What was that? My, My, Please use your words, whore.”

 

“—𝘈𝘩𝘯! T-that’s…I…you wouldn’t…”

 

“We don’t have all the time in the world, Tanjirou,” Shinobu hums, running her fingertip so carefully over his nipples, and his small jolt at the mere touch made a pink hue settle over her face. He was just, too cute wasn’t he?

 

She applies enough pressure so the entrance gapes around the tip of her strap-on; she held onto his hips, making sure to stop him from rocking his hips back, as needy as he was, and she let herself sink in until at the hilt she was burried, all bottomed out. And she gazes down at her Tsuguko, who can’t stop writhing around below her body.

 

“Please…!”

 

“My, surely a slut like you knows what you want,” Shinobu encourages.

 

“Fuck me already, please…!” Yuuji cries out.

 

“Please what?”

 

Tanjirou starts sobbing, too frustrated by the lack of movement. “Please, ma’am!”

 

Shinobu grins, “See, it wasn't so hard, after all."

---

Tanjiro is left to wonder if his endurance training with Shinobu was, normal, 
He asks Mitsuri, and is far more than flustered.
