#SukuItaWeek2021 Day 1

Prompt: Bondage

#SukuIta #RyouIta

CW // incest, shibari/kinbaku, a/b/o, a!Sukuna, a!Ryoumen, o!Yuuji, breeding, spit, biting/marking, blood, technically a Yakuza au

Summary: Yuuji learns kinbaku/shibari (sorry idk the proper terminology) from Megumi and convinces Suku-nii to let him try it on him. Suku-nii might have some regrets......

Ryou-nii will show up too, but later on.

///////////////

The room is unusually silent as Sukuna watches his little omega brother kneel between his legs, pink tongue peaking out between his lips as he concentrates on the ropes in hand.

It'd taken a /lot/ of whining and begging and pouting from Yuuji to get the older alpha to agree to-

being tied up. If the boy hadn't looked so sad every time he was told no, maybe Sukuna wouldn't be sitting on their bed with thick red ropes wrapped around his chest and abdomen, binding his arms behind him.

If the heady scent of omega slick wasn't dulling his senses, Sukuna-

might've put a stop to this nonsense before Yuuji finishes his last knot.

The omega stands up, hands on his hips as he looks the ropes over before a perky, self satisfied grin breaks through. That /almost/ wipes away the regret Sukuna currently feels.

If that damned assassin-

Hadn't been busy teaching his son these things, then Yuuji would never have picked it up from Megumi. Sukuna has half a mind to order the other alpha's execution just for this, even if he was their clan's best asset. It's a shame his twin, Ryoumen, probably wouldn't agree to it.

His thoughts turn back to Yuuji as his little brother begins to busy himself rearranging the bed. The alpha is confused for a moment, why was he building a nest when he wasn't on heat?

Sukuna /hates/ the yelp that slips out when Yuuji grabs the ropes and yanks him backwards.

The ropes are layered such that it didn't actually hurt, but the casual reminder of his little brother's strength caught him off guard.

Yuuji finally maneuvers himself onto his big brother's lap, completely naked. Sukuna can't help but admire his brother's soft yet built form.

((A/N: The ropes around Sukuna's chest/abdomen look like a mix of the first 2 pics, and the ropes at his back/tying his arms look like the last 2. Just more rope on Sukuna though bc he's *very* strong, esp when horny.

Also do NOT "yank" on people when they're tied up lol!!!!!!))

A growl reverberates through Sukuna's chest as Yuuji tries to push him down. The little omega pouts at his brother. "C'mon Suku-nii," he whines. "I arranged the pillows for you so you can lie back without being too uncomfortable. You said you wanted it like this."

Sukuna grits-

his teeth at the goddamn brat but lays back and finds himself surprisingly comfortable. It's true, he *had* told Yuuji he'd only agree to being tied up if he was on the bed, rather than being tied to a chair like this brother initially wanted to do. This gave him /some/ freedom,-

at least he could move his hips to fuck up into his little brother.

Wiggling his hips happily, Yuuji braces himself on his brother's strong chest as he leans up to kiss him. Sukuna might've been trying to play it cool, but his head lifts eagerly to meet his brother's lips, soft-

and warm against his own.

Yuuji tries to take his time, keep it sweet. But Sukuna's will soon overpowers him, the alpha quickly taking control of the kiss, nipping hard and licking into the omega's mouth. Even though he has nothing to hold Yuuji in place, the omega melts into-

the kiss. The taste of his alpha floods his senses until he can barely pull away, gasping roughly for breath, going a little cross eyed as he looks at the string of spit connecting his bottom lip to Sukuna's.

Licking his lips as if to relish the taste, Yuuji slips his hand down-

between them to palm his brother's cock, already rock hard for him. Sukuna's eyes nearly roll back into his skull when Yuuji begins to rub his pussy along the length of his cock. Both brothers stare down between them, mesmerized at how the omega's pussy squishes around the shape-

of his alpha's cock, all pink and soft and wet. Yuuji's hips roll at an unsteady pace, following the spike in his pleasure as Sukunas knot begins to form. It provides Yuuji with the perfect thing to grind on. Soft whines sound in the omega's throat, answered by Sukuna's guttural-

snarls as he grows desperate for more than just a warm pussy sliding against his cock.

Yuuji finds himself approaching that edge of pleasure all too quick. Delicate fingers dig into Sukuna's chest as his omega's hips roll at a frenzied pace. Drool drips down onto him as Yuuji-

pants, open mouthed.

"Su-Suku-nii, please can- /ah/ c-can I cum? /Please/ let me cum, Alpha."

Sukuna grins half feral at Yuuji's begging. His brother might be the one tied up, but Yuuji knew better than to cum without his alpha's permission.

"You're a good little omega,-

aren't you, Yuuji?"

The boy nods frantically as he babbles words that only half make sense. "Y-yes go—od, f-for Alpha— want to- please pleaseplease, Alpha, Suku, c-can't—."

"/Fuck/." Sukuna groans, leans up to press his forehead to Yuuji's. How was he the one tied up, yet his-

little brother already sounds ruined.

"Yes, /such/ a good boy for your Alpha. You're going to cum for me now, get my knot all wet because your slick is the *only* thing you get to use today to get my cock in that tiny little pussy. I don't give a fuck if it hurts, you're going-

to take it like the good little omega you are. You're going to fuck yourself on my cock, somehow force my knot into you, and breed yourself on me, because your Alpha says so."

Yuuji's voice breaks as he cums on his older brother's cock, slick gushing so much that Sukuna wonders-

if it was /just/ slick.

Yuuji slumps against his brother's chest, body shuddering with the after effects of his orgasm. Sukuna takes the opportunity to nuzzle into his brother's throat, licking slow at that intoxicating scent gland. Simultaneously he rubs his scent along-

Yuuji's jaw to calm the omega. Slowly the boy regains his senses, kissing up Sukuna's strong shoulder
Yuuji mouths at the sensitive scent gland, tongue tracing the marks of his reciprocal mating bite on his alpha. He's tempted to renew the bite, but holds off on doing so.

Reaching down, Yuuji grips his alpha's cock by the knot, drawing an almost pained groan from the bigger man. Yuuji gives it a stroke or two before tapping it against his own belly, unperturbed by the slick smearing on him with the wet slaps. He always enjoyed the sight of his-

brothers' cocks reaching his womb tattoo. Showing him just how deep they were going to breed him.

///////////////////

((TBC, I hit tweet limit so will continue when I wake up in like 8hrs, promise! I hope y'all like it so far 💖))

"Fuck, Yuuji." The alpha groans, impatient and painfully hard. "Quit stalling, be a good boy, let Suku-nii use you."

A wicked grin splits Yuuji's lips as he shifts off Sukuna's lap, the alpha's cock smacking heavy against the ropes wrapped around his stomach.

"Where the fuck-?"

The alpha's words die in his throat as Yuuji turns around and bends over to present for his alpha. This exposes the pink diamond topped plug Yuuji is wearing.

"Which hole do you want to use, Alpha?" His voice is obscenely innocent, pretty fingers spreading his pussy for Sukuna.

Muscles bulge as Sukuna strains against the ropes. They shift and creak but don't give way, Yuuji knew what it took to restrain his brother, momentarily at least.

Sukuna contemplates just getting up and pinning Yuuji down with his body weight and teeth. He could blindly try to-

fuck into him. But that would take too long.

No, he'd play Yuuji's game, and make the little brat do all the work. Forcing himself back down, spreading his own thighs to show off the thick, heavy knot already formed. It's hell not being able to cum without something around his-

knot, but he'd soon rectify that.

"Brat, didn't your Alpha already tell you you're going to get bred?" Sukuna gaze is almost hypnotic as Yuuji stares over his shoulder. His breath shudders. "Get that little pussy of yours on my cock, /now/."

Sukuna infuses the last word with a-

commanding growl. And it works. Yuuji, eyes half lidded, brain overriden by his alpha's command, turns around and climbs back into Sukuna's lap. It's only when he's got the cock teasing at his hole that he snaps out of it with a gasp.

"Suku-niiiiii," Yuuji whines, scowling down-

at his brother. "You said you wouldn't do that either."

"That's before I knew my dear little brother was such a brat." His hips rut upwards, but Yuuji is prepared for it and moves away just enough. "Now stop being a fucking tease and- /FUCK/."

Yuuji catches him off guard for-

the second time as he sit down on his brother's cock in one go. His slick does little to help ease the way, Sukuna always stretched him too wide. Short breaths squeak out of the omega as he sits ram rod straight on his alpha's cock, mind blank. He hasn't even taken the knot yet-

And there's already a bump in his belly, just above the womb tattoo.

He brings a hand up to pet it and gasps when Sukuna's cock twitches inside him. The older alpha is transfixed by the way his little brother's pussy swallows him up. How its split open on his cock, yet squeezes-

around him as if trying to pull him even deeper.

The omega whimpers when Sukuna rolls his hips upwards, yet doesn't stop him even though tears shine in his eyes. Eyes that are glassed over, vacant as if he were enthralled by the alpha.

"Yuuji, come give your Alpha a kiss."

A shiver runs through his young body as Yuuji leans up to kiss his brother, lifting himself partially off Sukuna's cock.

The alpha sinks his teeth into the soft bottom lip, drawing blood and a sharp cry. Yuuji sits back, eyes sharp and indignant. His blood stains Sukuna's teeth-

as he smirks up at his brother, showing off the bloody fangs.

"Fine, I think it's *your* turn to be a /good boy/, Suku-nii." Yuuji's snarl is half feral and uncharacteristic to most. But Sukuna knew better, this was his little brother at his most uninhibited, his most beautiful;

blood dribbling down his chin and a dangerous spark in his eyes.

The first few rolls of his hips are steady, the omega seemingly unruffled by the way the cock moves white hot against his insides. But soon the stimulation isn't enough. A frustrated whine breaks his composure and-

Yuuji shifts onto his knees, hands gripping the ropes banded across Sukuna's chest to steady himself.

The alpha drops his head back with a loud moan as his little brother begins to bounce on his cock. His pussy is tight and wet and /hot/ as it slips up and down Sukuna's cock.

((TBC sorry it's short))

New CW // explicit mommy kink, knotting, breeding, threats, dubcon(ish)

((Rip sorry for not updating for so long 😔 Sukuna and Ryoumen are kinda bitchy @ each other bc they're both alphas and hate sharing Yuuji))

Pained whimpers have turned to gasps of pleasure. Sukuna's cock always makes him feel so full, drives all thoughts from Yuuji's brain. The boy has to struggle to remain in control of his own body, let alone the alpha. With every drop down onto Sukuna's lap, Yuuji can feel his-

knot spreading him even more, trying to get inside the tight heat.

The sensation promises overstimulation, Yuuji knows if Sukuna was in control he would've forced his knot in by now. It adds to the layer of smug pleasure when he pulls up, denying his brother that release.

Sukuna's lips are parted, moaning profanities and threats as Yuuji chases his own pleasure, stringing his brother along with the promise of an orgasm with every downward slide of his hips. And then ripping it away when he doesn't take the knot.

"Little fucking whore of a brat,-

why don't you come closer?" Sukuna's fangs dig into his lip the more Yuuji edges him, growls growing more vicious by the moment. He struggles against the rope so hard Yuuji is surprised he isn't seeing bloodied wrists. "When I get out of this I'm going to snap that pretty little-

spine of yours, then you'll have no choice but to lay there and take whatever the fuck I give you."

"Tsk, Suku-nii, it's not nice to make false promises, yknow," Yuuji chides the alpha, then laughs as he tries to sit up and take a bite at him. But Yuuji can't hide how the-

alpha's threats make him involuntarily squeeze tighter.

Bright blush settling on his cheeks, Yuuji slips a hand between them to press the bump that keeps distending in his tummy. The sensation makes him tremble but draws the deepest purrs from his brother.

"Fuck, you're so tiny you can't even fit oniichan's cock properly, yet you take it all, such a good omega."

Yuuji preens at the praise, rewarding Sukuna by changing the motion of his hips. From a simple up down rhythm to a slow grinding roll against his knot. He doesn't even-

reprimand Sukuna when the alpha starts to roll his hips up, determined to fuck his knot into his little brother's pussy.

"You're so fucking full, can barely fit my knot in you, fucking split your pussy open when I get it in, gonna be fucking and cumming directly into that-

little womb of yours." Sukuna is too busy rambling, focused on how Yuuji's hole is trying to milk his cock to hear their front door open. "That's it, good boy, stay right there, let your Alpha use you."

Caught up in the praise, Yuuji let's his guard down for a split second.

That's all it takes for Sukuna to surge up and sink his fangs into the delicate shoulder, drawing a pained cry from his little brother. Still tied up, Sukuna uses his bite to hold Yuuji to him as he flips them over so his body pins Yuuji under him. The boy struggles and cries-

beneath him as he starts to force his knot into the omega's hole.

"Suku-niiii nooo /stop/..."

Sukuna's moans drown out the soft cries beneath him, and he relishes the metallic tang of Yuuji's blood on his tongue. He's got his knot about half way in when their room door slams-

open with a loud bang,startling both brothers.

In the doorway stands their third and oldest brother. Driven by possessivd instinct, Sukuna makes the mistake of letting Yuuji go to snarl at his twin.

"Ryou-nii~!"

"No, no, no, n- FUCK."

Sukuna yells in frustration as Yuuji-

quickly slips out from under him. The alpha rolls onto his back once more, his cock hard and leaking against his stomach. His twin looks over at him with a raised brow, meeting his glare with a smirk to looks too much like his own. Fucking bastard, Sukuna thinks to himself as he-

licks the blood off his lips.

Yuuji is ecstatic as he flys into Ryoumen's open arms, neither caring that he's all bloody and slicked up. The omega claws his brother's shirt open to nuzzle bare skin and scent him.

"Having fun, Omega?"

"Mhmm." Yuuji mumbles, cheek rubbing against a firm chest.

"I see Sukuna was too weak to refuse your demands." Ryoumen laughs, head dipping down to lap at the fresh bite. He ignores the growl that sounds from the bed, instead starting to pull his clothes off. Yuuji's hands-

immediately drop to his belt as Ryoumen tilts his head up for a kiss. His own big hands roam the omega's body, touching and pinching at he pleases.

He doesn't break the kiss until he feels Yuuji's hand around his cock. The boy is panting and light headed but gives his eldest-

brother a bright smile anyways.

"Ryou-nii, will you join us?"

"Tch, how could I say no to a face like that?"

Yuuji giggles in delight as Ryoumen scoops him up to carry him over to the bed and drop him next to Sukuna.

"Fucking piece of shit, I'll fucking kill you, Ryou."

"Suku-nii, thats mean, don't be so grumpy." Yuuji crawls over to him with a pout, unfortunately dragging Ryoumen along. "Mommy always said you two had to share."

"/Fuck./"

The groan is wheezed out of Sukuna as Yuuji straddles him and slips down onto his cock in one luid motion.

His head falls back as pleasure borders on oversensitivity, and he misses the cruel smile steetching across his twin's face.

"Y'know, Yuuji, maybe you should play as Mommy sometime." Ryoumen kneels behind Yuuji, toying with the jeweled plug before slowly pulling it out.

Yuuji nearly collapses on Sukuna's chest, while dark red eyes glare up at Ryoumen. "I'm sure Sukuna would follow your instructions much better, he wouldn't want to disappoint Mommy."

Sukuna flushes a dark red, eyes rolling back as his hips jerk up involuntarily. Yuuji twitches-

around him and it takes him a moment to realize his little brother wants that too.

"I-is that what you want, Yuuji? Want me to call you Mommy while I fuck you? Maybe I'll put a couple cubs in you, then you'll be a real mommy."

Yuuji whines, face buried in Sukuna's shoulder.

Ryoumen takes the opportunity to start to ease his cock into his little brother's other hole. There's copious amounts of slick to ease the way, but the stretch makes all three of them groan as both cocks are practically rubbing up against each other through Yuuji.

"Y-Y'know, /fuck/, I bet Ryou would /love/ to fuck Mommy too."

"Sukuna." A warning growl rumbles through Ryoumen. He grabs Yuuji's by the back of the neck to hold him in place as he forces the last few inches of cock into the omega. Sukuna nuzzles lovingly against Yuujis cheek,-

((thread limit, give me a couple mins))

as his brother clings to him, shivering as he's stuffed too full of their cocks.

"I bet he'd even let you tie him up too if you tell him /Mommy/ wants it."

"Shut the fuck up, /Suki/." Ryoumen snarls down at his twin. The younger Alpha bares his fangs at the mocking nickname-

before spitting at his brother. Ryoumen doesn't even flinch, just grabs Yuuji's hair pulling his head up and twisting it to face him. "Yuuji, be a good boy and lick."

The omega, stuffed full of his alpha's cocks, surrounded by their heady scent, is barely aware of what's going-

on anymore. Golden eyes are glassy as he follows Ryoumen's order, licking up the spit on his brother's cheek obediently. Both cocks are twitching in his guts as the alphas watch him submit to their wills. The pleasure is coiled so tightly, Yuuji isn't even sure he *can* cum.

He's proven wrong in the next second when Ryoumen pulls out and slams back in. Yuuji's nails draw blood as they sink into Sukuna's chest. Eyes rolling back into his skull, Yuuji arches up as his orgasm spikes through him, his mouth dropped open in a silent scream.

Both twins stay still as their little brother falls apart between them, squeezing tighter and tighter with each ripple of his orgasm.

It's not until Yuuji slumps forward against Sukuna's chest that Ryoumen starts to move again. The young body twitches between them as both cocks-

begin to overstimulate the omega. Sukuna is back to nuzzling Yuuji, promising him a nice big knot that's going to knock him out for the rest of the day.

"Don't lie to our little brother, you're not giving him your knot today, maybe don't piss me off next time." Ryoumen grins-

down at the immobilized alpha. But surprisingly it's Yuuji's whines that answer him.

"Noooooo, R-Ryou-nii, I-I want, I wanna-," the boy mumbles, brain still scrambled from his orgasm. "I wanna be a Mommy."

Ryoumen's next thrust is harder than he means it to be, both alphas-

going wide eyed at their brother's request.

"Please, please pleasepleaseIwannabeamommy." The omega is already slurring his words, half out of his mind, but his alphas will be damned if they don't take this chance.

In the blink of an eye, Ryoumen slices through the ropes with-

his claws, freeing Sukuna. The twins work in sync with each other. Ryoumen wrapping his arms around Yuuji's stomach and chest while Sukuna hooks those pretty legs over his arms, both moving closer til Yuuji is practically bent in half between them.
