This was wrong.

Every single thing about this was so wrong.

"God damn... Your mouth— Look at me when I talk to you, brat."

But it felt so good.

Yuuji could barely see through his tears in the dimly lit room. His uncle's figure was hulking over him like a mountain. A man in his fifties was keeping him on the floor, back up at the side of the bed, with his head tilted back. His throat was stuffed full, and he swallowed, feeling his muscles constricting around thick shaft. He moaned, looking up through cum-stained lashes and meeting red eyes. Sukuna smirked, grabbing his hair and tugging Yuuji off his cock. Filthy slurp of omega's lips was loud in the middle of the night. His mouth popped off the thick tip with a wet sound, and he breathed in deeply.

"Still hungry for it, kozo [1]?"

Rasp of alpha's voice made Yuuji squirm. His head nodded without him even registering, and he whimpered in the back of his throat when hot flesh rubbed on his cheek. 

His uncle smelled divine.

Rich and powerful, his scent was making Yuuji's head spin, and he mewled incoherently, barely able to get his thoughts straight. He followed flushed tip that oozed thick precum, licking it off and humming at the taste. It was musky, true alphan odor rolling onto his tongue like a syrup. He was ripped from his haze by a deep chuckle and rough tug on his hair that made him shudder in want.

"If only my brother knew what his little sunspot is doing at nights."

Yuuji, to his own embarrassment, moaned at that, still trying to get alpha's cock back into his mouth. His uncle didn't let him, cruelly pulling his hard cock away every time Yuuji got too close. He rubbed hot tip on his lips teasingly, his breath barely hitching while Yuuji was panting in arousal. Hot flesh was rubbing into his cheeks, collecting cum from his face and pushing it into his mouth. Yuuji licked it off eagerly, only welcoming addicting seed. He wiped his eyes and sniffled, on the verge of tears, looking up at the alpha. Pulling the saddest puppy eyes he could, he whispered, feeling his panties getting drenched with his slick as he rubbed his thighs together.

"Please. Please, oji-san [2]."

His voice was hoarse from previous throat fucking, but it somehow only made his belly twist more in arousal, heat rising under his skin. He sounded beyond fucked out. He couldn't imagine what he looked like, sitting on the floor in his cum-soiled sleeping shirt and soaked panties, waiting for alpha's cock to ruin him for the third time this night like an obedient slut. Though the sight must have been good for his uncle as the grip on his hair tightened. Omega breathed in, ready for a rough thrust of powerful hips. With a quiet snarl, Sukuna let him have his cock, pushing into his mouth. Yuuji latched onto it like it was his lifeline, sucking it eagerly. Corners of his lips burned, but he didn't care. He swallowed more and more until his nose brushed thick pubes and his chin was pressed on alpha's heavy balls. Intoxicating scent of a mature man, the musk of want and lust, made him keen with cock in his mouth. He felt a thick bump of knot throbbing, ready to swell and let out a guttural sound. The vibration from it must have felt heavenly as Sukuna groaned, his scent bursting, and Yuuji took a couple of rough thrusts like a champ. He opened his mouth wider, accustomed to alpha's humongous size, and relaxed his jaw and throat in a habit that he acquired in his regular night endeavors.

He wasn't able to resist the presence of the first mature alpha in his home.

As soon as Sukuna moved into his father's house from another city, Yuuji knew he was doomed. He got scent drunk at their first dinner together, and while his dad was chatting, happy to be reunited with his brother, Yuuji was gripping his utensils, trying to not let out a submissive keen. That night he fucked himself stupid in the darkness of his room. Cheap dildo did its job, but orgasms felt underwhelming. He soaked his bed, writhing in fantasies of an older man pinning him down and taking him roughly. Making him lose his mind and beg for more.

The next day, a knowing smirk on his uncle's face made Yuuji's cunt throb.

He lasted only one week.

Silent glances and long stares of red eyes were making him hot and his panties wet. His uncle, besides being unfairly handsome, had a dark magnetism in the way he held himself. His posture, his scent, everything about the older man was attracting young omega. He never felt this incinerating lust and want towards his alpha classmates. Even the pace of Sukuna's speech had Yuuji enthralled.

Omega knew it was bad. It was unacceptable: they were related, and Sukuna was well into his fifties while Yuuji was still in high school. It was wrong on so many levels. But lonely nights when he was fucking himself till his cunt couldn't take it anymore were driving him insane. The coldness of his bed and the empty feeling of orgasms made him shuffle out of his room one night and go to the one at the end of the corridor.

That night he got a taste he'd never forget.

And ever since he craved it.

"Hmm... You are distracted, kozo."

Yuuji spluttered, not able to hold off his disappointed grumble when alpha pulled out with a squelch. His cock was glistening in the light of the lamp, thick and veiny, heavy under its own weight. It could destroy Yuuji's cunt so easily, leaving him gaping and wanting, with thick cum oozing out of him. He would try to keep it in, clenching real tight so alpha wouldn't be able to pull out. He would make Sukuna knot him, like a good omega. He could take it. His pussy was so greedy for the fat glands to lock it and make that hot seed take. He might even take it up his ass. The stretch would be so fucking good. Yuuji might limp afterwards, but he wouldn't regret it. He'd go down on his knees again and lick him clean and ask for more. He was sure he could take it. He could take knotting; his cunt was pulsing with the thought of it. His ass would struggle a bit to take in alpha's manhood, but he would bet it'd feel more intense.

For now, he only had his mouth knotted.

And it had him coming without touching himself.

He couldn't imagine how it'd feel to come with that monster in his pussy or ass.

Yuuji was ripped out of his horny thoughts when he suddenly was thrown on the bed. His head hung from the edge, tilting down, and he gulped at the intimidating figure of his uncle above him. A warm, rough hand grabbed his neck, encompassing it entirely, and he moaned, feeling slick rushing down his legs.

Fuck. It shouldn't be so hot.

Sukuna smirked, taking his cock into another hand and stroking it slowly. His fingers got coated with Yuuji's saliva and pre-cum as he jerked off right above his head. His balls were hanging low, and in a desperate attempt, omega touched strong thighs, trying to pull the alpha closer. A low chuckle made his face hot when the man stepped closer and a warm sack brushed Yuuji's forehead. He latched on to the balls immediately, taking them in his mouth. One, then another, rolling and mouthing on them. His nose kept bumping into a slowly swelling knot, and he laved it with his tongue, feeling how precum was dripping on his chin and neck as alpha kept milking it on him.

"Slut."

The slap of cock on his face made Yuuji moan, and he kissed the underside of the throbbing cock lovingly, looking up at alpha. He made sure he kept his attention as his tongue swirled on the large shaft on his face and his fingers rolled alpha's balls. He sucked on pulsing veins, mewling in need, and tried to slurp on the thick tip. But alpha's cock was so long that the tip brushed his chin, laying past his lips. He opened his mouth wider, catching it with a satisfied roll of his eyes, and nursed on the spongy flesh.

It shouldn't feel this good.

"Please... Oji-san... Let me? I can take it... You know I can..."

His pleas made alpha chuckle, and a massive hand on his neck squeezed it reassuringly.

"Of course you can, boy... I trained you well. Now open."

It should be embarrassing how fast Yuuji dropped his jaw and took a deep breath. But his mind was empty, and he waited for his throat to be used like a fleshlight.

Thick hot girth pushed into his mouth. They did it like this for the first time, and Yuuji almost gagged. He grabbed on alpha's thighs in a weak attempt to stop it. But of course, his uncle wasn't going too.

"If you want me to knot your mouth, kozo, you better start acting like it."

Yuuji felt his mind fogging at the thick scent of alpha's arousal. His own was swirling in sweet waves as he relaxed his throat and swallowed. His eyes were rolling back into his head from pleasure. He felt his pussy pulsing eagerly. He was so close to coming without hands again, it was ridiculous. Heavy balls smacked him in the face as alpha pushed deeper with a low growl. That made Yuuji clench his throat, eager for praise, and a low moan, a rare sound from an older man, made his heart flutter while his mouth was stretched obscenely.

"God damn... Good boy. Shh, breathe."

That was the only warning before Sukuna pulled out and thrust in. His sated groans of pleasure bounced off the walls while Yuuji was lying on the bed, taking it. He was holding onto strong thighs, swallowing and spluttering with his spit and alpha's precum that coated his entire face after a couple of rough thrusts. It was so filthy. Everything. Squelching sounds of the flesh moving in his throat. His own whimpering, pathetic sounds of joy as he gulped alpha's length like it was nothing. His uncle's ragged breath and sudden snarls when Yuuji tightened just right for him. Smacks of balls on his face, quiet lewd plaps as alpha was using him.

This was what heaven must have felt like.

"Shit... Want to make your pussy take me... With the way your mouth is so eager, I wonder if your cunt is needy like this."

Yuuji moaned through dirty, whorish sounds that his throat was letting out as cock in his mouth was ramming in and out. Alpha's knot was swelling, promising a hot load of thick cum down his throat. He wished it was in his pussy though. He wished it overflowed his greedy cunt, making him leak for days.

His mind was hazy as he completely lost track of time. Only strong pistons of alpha's thighs mattered. The fullness of his mouth and throat, stuffed to the brim and stretching even more in preparation, was making his pussy throb. He was close, so close—

"Hm... I guess you deserve a little treat."

Before he could process what was happening, Yuuji felt the hand that was holding his neck this whole time, keeping him in place, travel down to his chest. It tugged his night shirt up impatiently, touching his pecs. He gained some weight lately, and it all went into his ass and chest, making them fatty and bouncy.

"You have the body of a whore, you know that?"

Yuuji was hyperventilating as his uncle was exploring his body for the first time in a month. He usually fucked his throat and let Yuuji nuzzle him a little afterwards, too relaxed after an orgasm. But he never touched him like this.

Like he was enchanted with him the way Yuuji was with alpha.

His rough fingers pinched his nipples, making omega gag. An amused chuckle didn't mask the violent throb that went through his cock in Yuuji's throat, and he wished he could purr to show how he liked it. But his mouth was busy swallowing and sucking as alpha squeezed his chest in two hands, fondling it.

"Damn. Look at these tits."

His uncle's breath was ragged, but his hips thrust remained steady. He continued to touch Yuuji, tweaking and pulling on his nipples and squeezing his breasts, and omega was basking in attention. Even though he couldn't focus long enough to predict where big hands would touch him. His head was foggy with pleasure, and he could only mewl in need as knot was finally swelling into its full must.

"Greedy bitch... Take a breath and get ready."

Yuuji squirmed, rubbing his thighs. His heart was racing. He was sweating so much. He hoped he smelled good as alpha rammed his cock with more urgency, making him gag. He didn't have time to recover, though, as thick girth plowed into his mouth like it was a hole in the wall. His cunt pulsed, and then he felt big hands pushing his thighs apart.

"I always miss this part, kozo. Come on, show me."

Fuck. Fuck.

Yuuji shuddered when thick fingers pulled his panties to the side. He could feel alpha's gaze on his cunt. He wondered what he thought of it. Was it too fat? His pussy was plump, with his clit hiding shyly and only showing when Yuuji was rubbing it all night, thinking of his uncle. Did he find it appealing? Did his uncle like the sight of it?

He got the answer right away when alpha cursed under his breath and his cock throbbed in his throat. The man stumbled in place and grinded deep into him. He kept Yuuji's thighs open with one hand, and the other was back on his neck, rubbing it insistently.

"Fuck. Mmm... That's right, boy. Take it."

His knot swelled in Yuuji's mouth, and omega keened. It came out as a gurgling nasty sound, and he was coming. His pussy quivered, empty and miserable but coming nonetheless. He must have looked pathetic, squirming like a worm on the bed. But soon hot seed flowed down his throat in thick ropes, and his head got empty again. He swallowed everything, tightening and clenching on the throbbing shaft and letting out quiet mewls of contentment. His nose was full of alpha's musk as he nuzzled a heavy sack. His tongue was restless, swirling on the hot bump of the knot in his mouth, and his uncle patted his cheek reassuringly.

"You did good, brat."

While Yuuji was high on his pleasure and alpha's scent, he felt a big hand rubbing his belly and travelling lower. He suddenly got hyperaware of every inch of his skin touched by a rough hand as it pulled his panties down his legs. He gagged, spluttering at the sudden sensation, and his uncle slapped his thigh, grumbling.

"I'm trying to reward you, slut. Stay still."

Fuck. Holy shit.

That was the only thought in Yuuji's mind when he felt alpha's body shift and lean over him. Hot breath fanned over his cunt, and he barely stopped himself from jerking when a scorching hot tongue licked him down there. His brain short-circuited when he felt a strong tongue run through his slick folds, and alpha hummed at the taste.

"...Should have done it sooner."

Another long stroke of alpha's tongue made Yuuji cry as he felt himself coming again. His pelvis shuddered while his pussy throbbed with sudden orgasm. He heaved through his nose, trying to calm down as alpha cooed and grinded his cock, pushing his knot deeper into Yuuji's mouth.

"Hmm... Virgins are too much work, but you're something else. Try not to bite me, brat."

With that, Yuuji's torture started.

He felt like he was actually dying, trapped under alpha, with his mouth knotted, while Sukuna was licking his pussy. No matter how much he squirmed and mewled, scratching strong thighs and trying not to bite down, alpha would only chuckle and hum at his taste. He was having a feast between Yuuji's legs; his mouth was hot, so hot on already warm skin, and a strong tongue was making omega see stars. He didn't know how many times he had come when another strong tremor went through his body. Maybe he was coming this whole time, as Sukuna didn't show any sign of stopping. His lips were mapping every fold of Yuuji's cunt. His mouth was sucking on hot, wet flesh, making omega's thighs tremble. He sounded sated and pleased as his tongue was slowly fucking Yuuji's eager hole. Loud slurping and filthy squelching were making omega's breath hitch as he dug his nails into alpha's thigh, coming again or just coming continuously; he didn't know.

He didn't know anything at the moment, quivering at alpha's mercy.

The man held his thighs open. The warm grip of his hands felt grounding as he devoured Yuuji's pussy. Sometimes he hummed and murmured something into his skin; Yuuji couldn't make it out. He could only tremble at alpha's mercy as Sukuna seemed to have the time of his life, licking him and drinking his slick loudly.

The sounds alone were making Yuuji's toes curl as he lay there, helpless and coming his brains out. He didn't know how much time had passed. He wouldn't be surprised if it was already close to morning. But soon he felt a thick knot deflating in his mouth. The taste of cum hit his tongue as the still hard cock was pulling out. His broken mind made him whine at the soon loss of the thick shaft in his throat, but then it thrust back, shutting him up.

"I'm not done with you, brat."

Yuuji felt hot breath fan over his crotch again when the cock, instead of pulling out after knotting his mouth, pushed in again. Heavy balls smacked his forehead as he clawed on alpha's thighs. He couldn't breathe, gagging, when hot lips sealed around his clit. He was so overstimulated by the cock in his throat, establishing yet another punishing pace, and by the teasing tongue that flicked on his clit, making his head spin. It was too much, too much, but he lay there taking it. Sobbing and crying in overstimulation, he struggled to breathe, but Sukuna only chuckled, sucking on his pussy.

It felt raw down there, and his belly tightened while alpha's dick fucked his mouth roughly. He trembled, helpless, and another wave of weak orgasm washed over him. His head was empty, and he felt numb, but then thick fingers pushed into him. He gagged again, snot, tears, and cum covering his face as his mouth was used like a fuck hole. The feeling of thick digits pressing into him and rubbing swollen walls of his pussy made him scratch alpha's thighs, and Sukuna snarled, biting his thigh.

"Fucking brat. Take what you are given."

And if before Yuuji had a fleeting thought that he was tortured, now he was sure he would die from coming his brains out.

There was no way he could survive this. Thick fingers, he couldn't even comprehend how many with his consciousness fading in and out, were stretching his cunt and fucking him in a steady, hard pace. His throat was fucked in deep, deliberate thrusts that didn't let him take a deep breath, and he was crying because it was all so much. His pussy felt swollen and raw, sensitive flesh quivering at every move of fingers in him, and when a rough thumb pressed cruel circles on his clit, he choked, grazing his teeth on the throbbing cock in his mouth.

"You little slut—Fuck!"

His uncle cursed, but Yuuji barely heard him. When the man pulled out, still looming over him, omega coughed but then wheezed when he felt his cunt throbbing around unrelenting fingers. He bit his lips, wiping his face and scrambling to pull away, but alpha growled, making him freeze.

"Where do you think you're going? Take it."

A couple of rough pumps made Yuuji sob, and he wiggled, trying to avoid them.

"O-Oji-san—I don't think I—"

"Don't think. That's my job."

Yuuji gasped when fingers pulled out of him and the room spun again as he was manhandled on the bed. He was dragged by his legs up, and soon he was sitting in Sukuna's lap. His shirt was ripped off of him in swift tug. Alpha's cock, thick and hard, bumped into his pussy momentarily, and Yuuji held his breath at the size difference. Monstrous length was intimidating next to his chubby, reddened pussy lips. Fat tip slid between his folds, hot and slick with precum and his drool.

Fuck.

It could ruin him.

It could make him come so hard.

To his own shame, his scent spiked in arousal, and he felt an amused chuckle with his back as alpha pressed him to his chest.

"Not today, kozo. I just want to see if you're good enough."

Big hands pushed his thighs apart, and while catching his breath, Yuuji bristled a little.

"I'm—I'm good! I can be so good to you, oji-san."

He whispered eagerly, nuzzling back into alpha. Their scents filled the room, and Sukuna hummed. He kept Yuuji spread on his lap, and his hand fondled his chest roughly, making Yuuji's mind sway.

"Is that right, omega?"

Yuuji felt his body grow soft at the command. A purr escaped his chest, and he slumped on the older man, feeling dazed and high. He felt himself drool, and a deep rumble of approval from Sukuna felt like the highest reward.

"Hmm. Cute."

Omega preened at small praise, nuzzling back with his head so blissfully empty. He watched a big hand, so rough and brutal against his vulnerable, soft stomach, travel lower, and two thick fingers dipped into him. A soft moan escaped his mouth, and then another two fingers pushed into his mouth. He latched onto them like it was a cock that he felt throb next to his thigh. He wanted it so bad.

He was so empty.

Though the fingers felt good. They were rough and steady in their movement, fucking him so good. His cunt was a wet mess; slick was glistening on big digits every time they pulled out. He watched them rub through his folds like in a trance, mewling around fingers in his mouth. His heartbeat was raging in his ears as he felt his orgasm coming. His belly tightened, and he bit big fingers softly, too sluggish to resist the pleasure for too long. He was sore all over, but it felt so good when fingers in his pussy sped up, now plowing into him with nasty, filthy sounds. His pelvis grew numb for a second, and then he saw his cunt letting out a spray of slick. He couldn't even hear himself moan around thick fingers as orgasm rolled through him for the nth time this night, leaving him boneless.

"I know you have more, little slut. Come on."

Those fingers didn't leave his pussy alone. Big palm rubbed on his clit insistently, and it felt like it was burning. Yuuji couldn't even scream; he felt so tired. But his body jerked on its own as he squirted again. He felt another wave of pleasure hitting him and drooled around alpha's fingers. They still played with his cunt, running through his folds and dipping into his eager hole.

Then those fingers spanked his pussy.

A harsh slap landed right on his clit, and he whimpered, orgasming again. The sated groan of his uncle was muffled as his blood was rushing in his ears. His cunt quivered, abused, and he watched himself squirt again. Yuuji grabbed on alpha's hand weakly, trying to stop it, trying to do something, anything, but the cruel chuckle made him moan. He slurred, tongue thick in his mouth as fingers pulled out of it and grabbed his thigh to keep him open.

"Oji—Oji-sa—Mhhh... Oh... Nnngghhh..."

"What's wrong, brat?"

"Mmm..."

Yuuji felt himself crying. It was so much. His body felt numb and lit up at the same time. His crotch throbbed as a rough palm landed on his cunt again, making him jerk in alpha's arms. He grabbed big hands but they just shook him off, continuing to spank his pussy till he was squirting again. Sheets were wet with his slick. His breath was shallow as he struggled to keep his eyes open.

Fuck.

Why did it feel so good?

"O-ji—Mmm... Oji-san—"

"What? Use your words."

He squirmed and felt his uncle's cock still hard and throbbing next to his thigh. Saliva pooled in his mouth, and he whimpered, turning his head up and trying to focus. He saw a smirk on the older man's face, and he looked pleased. Yuuji noticed how alpha's mouth and chin glistened in his slick and shuddered in want. His heart fluttered, his inner omega rolling in delight, and he whined, pleading.

"Y-your—Your cock—Please? Please! I—Mhmmm... I wanna—"

"Such a good slut for me. Come one more time and I'll let you have it in your mouth."

Yuuji whimpered, feeling a warm hand cupping his abused pussy. His pelvis was numb, and he shook his head.

"I-I don't think I can—Oji-san, please? Oh..."

"Don't be silly. You are born for this, kozo."

His deep voice was enchanting, and Yuuji sighed helplessly, feeling how his legs were opened again. He braced himself but still wasn't ready for harsh slaps on his cunt that made him squirt again. He sobbed while alpha snarled something under his breath, rubbing his pussy. Yuuji saw him lick his hand, and it was one of the most erotic things he saw the man do. He closed his eyes just for a moment, exhausted but trembling with pleasure, and when he opened them again, he saw a thick cock laying on a hard stomach.

He reached for it, smelling alpha's musk, and soon he was between Sukuna's legs, nursing on his cock like on a pacifier. He sucked and licked, listening to pleased groans and feeling his pussy aching. Big hand was in his hair again, moving his mouth on hot cock. He looked up and saw Sukuna watch him closely. Feeling heat in his cheeks, Yuuji batted his lashes, pulling off with a lewd pop. He was sure he looked like a cheap whore, but alpha's gaze was making him want to preen.

Nuzzling into coarse pubic hair and stroking alpha with tight movements, Yuuji dared to ask.

"Oji-san... Could you—Could you fuck me?"

His voice was hoarse, and he thought alpha didn't hear his whisper. But a big hand ruffled his hair almost lovingly, pushing his mouth back on hard cock. His voice came out rather affectionate, making Yuuji's cunt throb in want again.

"Spoiled little shit."

The implication in deep rasp made omega squirm in place. 

Oh fuck.

Fuck.

Yuuji was going to be ruined.

He couldn't wait.

Chapter Text

Soft moans rang in the air, and harsh tugs on his hair made the alpha smirk. Flesh under his mouth quivered, and he felt a wave of satisfaction roll through his body when lean thighs on his shoulders trembled.

"Oh, fuck! Fuck, I—Fuck!"

Sukuna never considered himself being so lustful.

He was sexually active, like any healthy alpha would be. His age didn't make things different for him in terms of finding a quick fuck. Instead, he was even more desired as young omegas were throwing themselves into his arms, seeking his attention and well, wanting to get railed by obviously well established older alpha in perfectly tailored suit and with expensive watches on his wrist. He had a lot of flings and sex was just a tool for him to let out steam. He liked it rough most of the time, not having patience to cater and please his partners.

But with his pretty little nephew, he suddenly felt generous. Perhaps, he should admit to himself that he was hungry for the boy's taste.

Sweet cunt gushed into his mouth as Yuuji cried out on top of him, riding his face, and alpha hummed, feeling his own cock aching. Trembling fingers carded through his hair as he sucked and licked, addicted to the taste. Looking up, he met honey eyes, clouded with want, and sucked on the throbbing clit cruelly, making the boy shudder.

"O-oji-san [1]! W-wait! It's too much—"

"If you want your pussy to take my knot, you need to relax more."

He squeezed thick ass cheeks, smirking at young omega, who shuffled back to his chest, panting. His face was red and blotchy from tears as his fourth (fifth?) orgasm left him sobbing. Cum was smeared on his pretty blushing face as he mewled and tugged on his nipples, trying to distract himself as Sukuna pushed him back on his face, not hearing any further objection.

Yes. He was greedy for the boy's taste.

A soft cunt was pulsing under his tongue as slick smeared on his face. Soft thighs felt like pillows as they clasped his head between them, suffocating him. His arms kept the boy on the spot, circling his slim waist and not letting him wiggle away from his pleasure. Hoarse moans and whines were muffled by thick thighs as Sukuna licked the poor abused cunt and slurped the nectar of the omega's slick.

He hadn't tasted anything more addicting than Yuuji's tight little pussy.

Initially, he thought his decision to expand his business in Tokyo was going to be troublesome. Transfer of his assets and all the documentation and revisions were giving him a major headache. He needed a place to stay until his house was ready to move in, and his past life was beckoning him back to his hometown, an hour away from the capital. While contemplating his decisions, he thought of how he's going to face Jin after all these years apart.

His first love.

His baby brother.

"Mmm! Fuck—I'm coming—Fuck!"

Hot slick splattered on his face and he growled, sucking on a quivering cunt. The boy definitely had a talent for making a mess. Alpha gulped it up, his knot throbbing to fill the eager pussy with his seed and get the brat all round with his pup. He let Yuuji flop on the side and heard him heave.

Getting up, he watched his sun-kissed skin glow and glisten with sweat as the omega was catching his breath. His legs were sprawled open, trembling. The reddened cunt was wet, oozing slick, and alpha licked his lips, still feeling the heat of it. Moving closer, he laid by the boy's side and Yuuji immediately nuzzled him, purring. Up close, he was a carbon copy of Jin, but there was a certain charm in him. Maybe it was his bubbly personality, a sunshine smile or his burning lust for the older man, Sukuna didn't know. But he felt himself being led by his lust for the past few weeks as the boy was dangling in front of him.

Coming to his late parents' house and expecting all his feelings to burst upon seeing the subject of his obsession, Sukuna forgot about his broken heart when he saw Yuuji for the first time. The honey eyes were wide, thick lashes fluttered and the scent of peaches invaded his nose, making his inner alpha perk its head while his cock twitched in his pants.

The boy smelled even better than Jin.

His omega brother was tainted by the bastard who Sukuna hated ever since Jin started dating him back then. The foreign scent was etched into a soft floral odor once the knot head bit his brother, marking him. Jin had no clue that Sukuna was burning with jealousy and unhealthy desires when they mated. Back then, Sukuna left his home in despair. His messed-up feelings towards his own brother were buried in the underground fighting that he got involved in when he was eighteen. He knew his parents were looking for him, but he never came back. 

Soon he got into a local gang. His anger and violence had a place to flourish as he was beating the soul out of people. His life got somewhat better or worse if anyone could judge, but at twenty-five he was feared and well known in the underground. Money was pouring, and he was always clever with it. At thirty, he opened a small business, a simple liquor trade. At thirty-five he built connections, still having ties with shady people. At forty, he was deep in business, sometimes illegal. It appeared that yakuza clans needed high-end liquor on their functions too, and he built good friendships among those people, getting police on his payroll. The past felt murky and distant, but he was watching, not able to let go entirely.

He knew that Jin got married. Sukuna was twenty-three at the time. He had some whores from the underground that were attracted to him, and he let them sooth his jealousy. A couple of years later, Jin got pregnant and had a round belly that he, Sukuna, had nothing to do with. Since then something in him snapped in two and his obsession grew dull with time. But he still wondered if things would have been different if he confessed. Or made Jin submit. With years, due to his violence that grew cold and calculative, his alpha status only solidified in the way his growls made people submit. He wondered if things would have been different if he went back and just took what he wanted. But alas.

He shut his heart, learning to enjoy his solitude and trying to let go. Though, he did have a smile on his face when he got the news of Jin's mate dying in a car crash. He was thirty at the time, starting fresh, and coming back to Jin felt like going backwards. He was glad that Jin was at work that day, though. Even if he was bitter deep down, he didn't want his precious brother to get hurt. Sukuna just knew that the bastard's son survived miraculously, only bearing a couple scars on his face as he heard from the people he sent to watch his brother from afar. As Jin grieved, alpha assumed he'll be alright since there was a kid that reminded omega of his mate.

But Yuuji didn't have any resemblance to his alpha sire at all.

He was Jin's son, through and through. A spitting image.

And Sukuna was a sick man with sick desires.

"One more time, kozo [2]."

He licked his own cum off of omega's cheek, making him gasp. His scent burst in arousal and Sukuna chuckled, taking him into a kiss. Yuuji was needy, his hot tongue, inexperienced, but eager, licked into alpha's mouth, seeking his own taste. Small soft hands touched his neck and arms, reaching wherever they could, and omega moaned.

"Mmm... Oji-san..."

"I told you not to call me that."

Flushed cheeks got redder as he cupped the chubby pussy, making Yuuji hiccup. His lips were swollen, a sinful image after a thorough throat fucking he got earlier. The minute Jin left the house for his work trip for the entire week, Yuuji was all over alpha. He was eager and needy for his approval, slicking up just at his scent alone. 

Before their night affair started, he watched the boy like a hawk. Yuuji was so obvious in his little crush. The way his scent swirled invitingly, seemingly without him knowing. Or how his face turned red when he caught alpha watching. Then his house clothes became more daring as he sneaked hot glances while Jin was gushing to Sukuna about how happy he was that they reunited after all these years.

Well. Alpha was happy too when his slut of a nephew crawled into his bed one night and sucked his cock like he had something to prove.

He has long forgotten about the bitter feeling in the pit of his stomach whenever he smelled Jin's odor. The scent of mature omega, his brother that he was lusting over all those years ago, had no chance in overpowering the mouth watering musk of young omega. It filled his lungs with his every breath, making him grind his teeth as he watched the boy suck on his popsicles, looking him right in the eye across the dinner table. The hungry glint in honey eyes stroked his ego, as Yuuji was almost presenting to him when they stumbled into each other in the house. He would apologize politely, tilting his neck in not-so-subtle submission. His scent would swirl, wanting and hot to even breathe it in, and Sukuna would smirk at the boy, watching his cheeks grow pink while his mind spiraled with every way he could fuck the teen so his brother wouldn't notice. It seemed he had a new obsession, enamored with his own nephew. 

In all his years, Sukuna never got such a picture-perfect omega in his arms.

Submissive, ripe and young.

A virgin, acting like a wanton slut for him.

Better than Jin could ever be.

"S-sukuna..."

"Good boy."

Honey eyes sparked at his praise, and he let the boy nuzzle him. His hips rolled into his hand, despite exhaustion after multiple consecutive orgasms, and alpha growled, making him whimper in need.

"Slutty little thing. Want my cock that bad?"

"Yes..."

"Tell me."

Yuuji squirmed and averted his eyes. Alpha watched his mouth drop open when he pushed his finger into the scorching hot pussy. Wet walls immediately clang on his digit, sucking him in with a soft squeeze. Omega's cunt was soft and chubby, the trimmed bush of his pubes was soft under his palm. He slowly fucked the boy, with one, then two fingers, making him whine and scratch his arms in agony.

"S-suku—"

"Come on, brat. Tell me how you want it."

Omega's reaction to his tone made him smirk. Yuuji looked at him with cloudy eyes, blushing furiously. He gasped when alpha's thumb rubbed slow circles on his abused clit and bit his lips, ruined and needy.

"I—F-fuck! I—Want your k-knot—"

"Yeah?"

"Mhm—Oh, god, yes! Yes! Fuck—I want to come on your cock—Please—"

"What else?"

Yuuji shuddered, trying to say something, but his eyes rolled to the back of his head as his back arched. Cunt under alpha's fingers gushed again and omega screamed, falling back onto bed. He was shaking, his legs snapped close, trapping Sukuna's hand. Alpha hummed, watching him jerk and moan, his hoarse whispers were muffled as he turned to burry his face into Sukuna's pillow. He continued to touch and fuck the boy's cunt, enjoying how his fingers slid on slippery skin and opening his legs.

"Don't want to talk to me, huh?"

Omega heaved, sobbing and babbling, not able to even think coherently, and Sukuna chuckled, kissing his open mouth. He whispered into panting lips, and kept the boy's eyes on him, raising his arm.

"Then I'll tell you what I want to do to you."

Honey eyes widened, and he smirked at the hot flare of the sweet scent. His hand swatted on soft chubby cunt and Yuuji screamed.

"FUCK!"

Slick gushed on the bed, drenching the sheets, and Sukuna felt arousal heating his guts. Jesus, the kid was really something. He rubbed on his pussy soothingly and kissed a soft cheek, whispering.

"I want to make you squirt on my cock, too. Turn you dumb with my dick."

He kissed a drooling mouth, catching whiny mewls. Thick thighs trapped his arm and he nudged them open. Pussy under his palm was hot and throbbing. Alpha cooed as Yuuji's hands were grabbing on his arm.

"P-please! No—No more—"

"Don't be silly, kozo. Remember? You are born for this."

Yuuji could only whimper and Sukuna shook off his hands of his arm. He kissed warm forehead, pushing away sweaty locks and his hand raised again.

"I want to ruin this tight little pussy of yours."

Another slap landed on omega's cunt and Yuuji wheezed, crying. His eyes were unfocused, he sobbed, and his trembling hands wrapped around alpha's neck, tugging him lower. Sukuna let him, rumbling in praise and feeling how sweet scent swirled as omega preened. Even exhausted, he sought alpha's approval and Sukuna kissed his sweaty temple in reward.

"You're so greedy for my cock, brat. You have a good mouth and your cunt is eager. I like that."

Yuuji nodded, nuzzling into his neck and his soft moans turned into shouts as Sukuna started to spank his cunt.

"Mm! F-fuck! Pl-Please! Su—Oji—Fuck!"

His legs kept snapping close, but alpha was relentless. Quick sharp spanks were turning the sloppy cunt red and hot slick was gushing into his hand. His cock throbbed in want to be buried in a messy, slick-soaked hole as he listened to soft cries and felt hot breath fan on his neck.

"I'll knock you up. Put a baby in you, so you're round and pretty with my kid. You want that?"

Yuuji sobbed, nodding eagerly and muffling his screams into his neck as his cunt gushed yet again, soaking alpha's hand and sheets. He moaned, long and needy, and Sukuna felt how his breath stuttered and fell steady all of a sudden. Pushing the boy on the side, he saw him unconscious, mewling in his knocked out state.

His knot swelled, and he snarled, grabbing it and preventing himself from coming.

Jesus Christ, the boy was about to milk him dry.

He let teen's body sag on his pillow, pushing between his legs. His crotch was soaked in slick, glistening. Rosy flesh turned red from abuse and Sukuna licked his lips, teasing chubby pussy with the tip of his cock. It felt scorching hot and wet as he nudged puffy lips, running throbbing length through the soaked folds. His cock looked brutal next to small pussy and he anticipated the sight of slick cunt, all stretched and gaping after he was done. 

Wet orifice felt impossibly tight, even after so many orgasms, and he groaned, pushing in. It clenched on his cock like a vice, making his vision swim with intensity of it. He smelled Yuuji's musk, swirling in thick waves and his own was bursting in want and need to plow into tight little cunt. He came, sudden and hard, and felt how his cum filled slick hole. Chuckling at himself for coming like overstimulated horny teenager, he let his knot swell, though he missed the heat of sloppy cunt on it. His cum overflowed, not locked by his knot and he watched it smear on flushed skin, making even a bigger mess.

His cock didn't grow flaccid, still stiff and wanting, with knot throbbing at the root. Pulling thick thighs over his own, alpha latched on puffy rosy nipple and started to grind into hot cunt. Slopy filthy noises of his cock slowly making its way into omega's pussy were loud in the room. Yuuji was still unconscious, mewling in his sleep. His light breathy moans were making Sukuna shiver in arousal as he kept rocking into him.

His little nephew was so eager for his cock that his greedy cunt was clamping down on him even in his sleep.

Alpha pushed and pulled, sucking on a plush tit. Yuuji's chest was small but bouncy, easily attracting alpha's gaze when he was prancing in his crop tops around the house. Sukuna wandered how big his little breasts would grow if the boy gets pregnant. How sweet his milk would be.

Just the thought of pretty young omega getting heavy with his pup made alpha snarl in want.

He teased soft nubs of puffy nipples, thrusting deeper. Breathy moans were echoing in the room as slick sounds of his cock fucking into a needy cunt soon shifted into sloppy slaps of alpha's balls on wet skin. His knot deflated, allowing him to push the entirety of his shaft in, and he shuddered, nipping soft skin.

"God damn..."

The entire bottom of omega's small body trembled, and he watched his pussy struggle to take him in. The boy moaned and, pushing in, Sukuna felt his cock throb at a tight clench. A second later, Yuuji let out a high cry, and his eyes snapped open. His pupils were blown, making his eyes dark and unfocused and alpha watched them roll back into his head when suddenly his groin got drenched. 

Holy shit.

"That's it, baby. Come on."

An affectionate pet name slipped out in the haze of his arousal and he rubbed on the engorged clit harshly, watching the flushed pussy squirt again. Slick spluttered, messy and hot, and he growled, pulling out and thrusting back into the sloshing cunt. Wet, tight heat fit him like a fucking glove, trembling and clenching as teen scratched his arms in agony of his pleasure. He was gulping the air like he couldn't breathe and Sukuna smirked, starting a brutal pace.

"—Mm—Ngh! Nggghaaa—S-Suku—Ah! Mgmhmmmm—F-fu—St-stop—Oh!"

"Take it like a good slut, omega."

Yuuji's body immediately slumped as his mind submitted at the command. Hot tears rolled down his cheeks as he moaned, biting his lips and clutching on his arms for dear life as Sukuna snarled, railing him up the bed. He wasn’t ready for the violent pulsing and desperate clenching of hungry cunt as Yuuji yowled, squirting again.

"God damn, brat—How many do you still have in you, hm? I guess we'll find out."

He chuckled, breathless and fucking into sloppy pussy harder, balls slapping into a wet mess between them, and omega screamed, eyes unseeing. 

"Oji—Oji-san! Mm! Alpha! Alpha!"

Sukuna cooed, pushing his legs up and feeling how his knot pulsed. Kissing open mouth and swallowing desperate pleas, he brushed his tears away, whispering.

"I'm right here, baby. See? Fuck, you're tight..."

Sweet scent burst with want, and he folded his nephew in half, pressing the boy into a mating press. 

Yuuji lost his mind completely. 

He was crying, drooling and mewling nonsense. He turned into a babbling mess, tears staining his pretty face, mixing with cum. His pussy was still squeezing tight and alpha fucked into him roughly, shuddering at incinerating hot clench. Roaring and feeling his knot swelling, alpha felt his cock pushing into something incredibly soft.

Jesus Christ, he was fucking his cervix. 

Realization made him snarl, and he couldn’t hold back any longer. With deep thrusts, he worked his knot into a sloshing pussy, feeling how almost painfully tight Yuuji was squeezing his knot.

Thick slick and his cum was frothing where his shaft pushed in, and alpha reached to play with a peaking clit. It was hard and flushed, tiny pink pearl that he flicked and rubbed on. A slick hole clenched impossibly tighter on his cock, milking him for cum, and Yuuji wailed, coming again.

“Nnnnhh—Pwe-please! Oh—Ohhnnnnn! I—”

“Mhm, that’s right, kozo. I’ll stuff you full. So fucking tight—Mhm, just like that... Take it, slut.”

Yuuji was sobbing, and when Sukuna plunged his knot in, grinding into a wet hole, his eyes widened and he keened. The most precious, the most submissive sound was breathy and so needy that Sukuna felt goosebumps rise on his skin. Alpha saw white for a moment when omega’s pussy clenched so hard around him, he thought it’ll break his dick. His knot pulsed violently, and he shuddered, feeling how his cock was still pressed into that incredibly soft spot of omega's womb. 

He was coming for so long, losing track of time. He took the boy into his arms, turning on his back and seeing sparks. Keeping Yuuji's body close and gripping his ass, he ground into soft cervix, still coming hard and long. The orgasm winded him, leaving him boneless and lightheaded. The satisfaction rolled through his tired body, making a deep ramble rise out of his chest. He didn't remember sex being this good, holy shit.

Omega on him whimpered, nuzzling, and he kissed sloppy needy mouth, feeling deft fingers card through his hair. It felt nice as whiny teen rolled his hips back on his cock, tugging on his throbbing knot. Yuuji started purring, nuzzling, affectionate after the dicking he just got. He turned to alpha, eyes sleepy but still sparkling. His blotchy face was flushed, and Sukuna reached for the corner of the sheet, wiping his cheeks. Somehow such a mundane action made Yuuji purr louder and Sukuna grumbled, clicking his tongue.

"Don't get any ideas, brat."

Yuuji smiled timidly and shifted again, knocking air out of him. His needy moan turned into giggles as he bit his lips.

"...You said you're gonna make me pregnant..."

Sukuna raised his brow and smirked at the teen. Palming thick ass cheeks and fondling soft flesh, he watched his face turn red. As if he wasn't begging and wailing for his cock for hours now.

It was adorable.

"You want that, kozo?"

Soft lips opened in shock and then he nodded eagerly. His eyes were still hazy and his pebbled nipples kept brushing on alpha's skin, making him want to suck on plush chest once more.

"Slut."

"...You like it though..."

Chuckling, Sukuna spanked the boy and fisted his hair. Yuuji's eyes drooped in submission, and he let out a needy mewl when alpha snarled. His cunt gushed a little when Sukuna kissed him roughly, whispering into his mouth.

"When you graduate, you'll tell your daddy that you want to go to Tokyo for college, understand?"

Nodding, omega licked into his mouth, seeking his taste but Sukuna snarled, making him whimper.

"Spoiled brat... Then you'll pack your bags and come to live with me there. My house is still under construction, but it'll be ready soon."

"...yes. Yes, I—"

"I'll make you my housewife. Get you knocked up and round. You'd like that?"

Honey eyes were wide and sweet scent burst in want. Alpha smirked at his eager nodding and needy mewls, letting Yuuji kiss him.

He was a sinner.

So was his nephew.
