Chapter Text

Strength had never truly been something he had searched for. But victory ? 

He craved to be the victor over all. He craved to rule the world, and do as he pleased, when he pleased, where he pleased. If he had to be the strongest to do that? So be it . 

Taking deep, shuddery breaths, Sukuna stood above the war raged battlefield, hands soaked with dark crimson blood as he alone continued standing. Two deaths in one day, two battles in one day. The victor of both. 

Grinning, all teeth and rabid bloodlust, the alpha took a long, deep breath. Taking in the scent of the iron and copper, dust and ripe peaches, honey and- 

Peaches?

Whipping his head around, Sukuna’s eyes easily zoned in on a familiar figure, mere feet away.

His omega .

“Brat.” His voice rumbled, loving and affectionate despite the carnage around his feet. He towered over his omega, and he couldn’t help the pleased note to his scent escaping as he realized just how drastic their size difference truly was, “Pick your next moves carefully. I’m in a good mood and I don’t want it ruined.” 

Itadori Yuuji slowly lifted his gaze from the floor, scent neutral, showing no sign of his next step. His honey ambered eyes slipped to the alpha’s icy sky blue eyes, and Sukuna could see the unshed tears. Itching to reach out and wipe his fears away, the alpha kept still, waiting in baited breath. 

Truly, Sukuna wasn’t sure what his omega’s next plan of action was. He had just murdered his teacher and an ally of his in their war against Kenjaku. What was his plan, wandering onto the field, giving away his position?

Watching his face, Sukuna was aware of his own allies and enemies rapidly approaching. Perhaps he was here to just keep him distracted long enough? Even so, he’d still win. 

The sound of footfalls fast approaching is what made the alpha first glance away. Instincts raged, to take his omega away. Tuck him away and keep him safe, where nothing could touch or hurt him. Looking back to the strawberry blonde, Sukuna’s eyes widened as he watched the omega move, slow and sluggish.

First, his head dipped down and towards his shoulder, chin hooking onto the bone. Completely baring his whole neck to the alpha, a true and undisguisable action of submission .

Second, he spread his hands and arms, up and towards the alpha, palms turned up, as if to grab onto the alpha. His hands shook, fingers twitching as if desperate to connect to the alpha’s own skin. 

Thirdly, the most sinful whimper. 

“ Alpha .” 

A shudder ran through Sukuna, and he grinned even wider. Beginning to laugh, he tossed his head back, all of his hands clutching onto nothingness. Oh, this was perfect. His omega. Fully submitting. All teeth, he looked back to his omega, pleased to note the boy was keeping with his pose, eyes fully closed. He truly, deeply, trusted him. Who was he to break the boy’s trust?

Stepping closer, two of his arms reached out for the omega. Yuuji kept still, though his eyes cracked open, watching the alpha. His alpha. Pride bloomed in his chest as his omega stepped into his arms, a simpering whine escaping his lips. Sukuna gathered him in his upper arms, a lower arm coming to cradle his cheeks. He smirked as Yuuji pressed into his palm, a shiver running through the omega.

Pulling him closer into his chest, the rosey haired alpha buried his face into his omega’s neck, inhaling deeply. His eyes rolled into the back of his head, hardly containing a moan as he realized . 

His omega was in heat.

The pride in his chest bloomed into a full blown ego boost as he realized his omega crossed the span of an entire battlefield to hunt down his alpha, so he could spend his heat with him. Grinning into the boy’s skin, he laved his tongue up the scent gland, squeezing the boy’s thighs slightly. Sukuna huffed deeply through his nose as the omega let out a soft moan, full body twitching a little. 

“ Alpha .” Yuuji pleaded, fingers threading through Sukuna’s hair, tugging gently. Allowing it, the alpha followed the motion reluctantly, peering at his teary omega. “Nest. Please ?” 

And oh, how could he refuse those honey eyes, and fermented honey spice scent?

Huffing into his neck, he pulled back, eyes sweeping over the space before him. He could see a few of his omega’s allies, coming from all directions. He could see the panic on their faces when they realized he had their friend in his arms. Grinning, ignoring their petulant cries, he turned and started off.

He had a safe spot to find for his omega.

“ Alpha ?” 

A shiver ran down Sukuna’s spine at the sinful little whimper his omega let loose, the strawberry blonde’s nose buried in his neck, snuffling and nosing at his scent gland. Eyelids fluttering at the feeling, a rumble formed deep in his chest as his omega began to nibble desperately at it, as if to drown himself in the alpha’s scent. 

“Easy baby.. Soon.” The alpha crooned, dully aware of the slick already soaking his omega’s pants, and subsequently his arms, from where he had him cradled. “We just have to get you to a nest.” Nuzzling his head gently into Yuuji’s, he purred softly. He shifted his grip on the boy, glancing forward. He supposed where he and Uraume had been staying would have to suffice. Yuuji wouldn’t last much longer.

Keeping his little omega close to his chest, his lower hands wandered up and down the boy’s body. Memorizing each inch and detail that he could. He was forced to not lay physical hands on him for so long. Gods know he’ll keep his hands on him longer then necessary. 

Taking measured steps into Tengen’s old maze like castle, Sukuna’s steps were quick and precise. Without thinking much, he was whisking his precious little omega away, towards his den. He, for once, was glad Uraume was right. He should have blankets and pillows and nesting material in his den, if his servant did their job correctly. 

Using his shoulder to shove the door open, he let his scent fully soak the large room before him. No bed, which only now made the alpha frown. Surely the nest wouldn’t be as comfortable. Reluctantly taking a spare arm off his omega, he pushed the door shut behind him. 

“Yuuji? Omega, baby?” Hearing the strawberry blonde whimper into his neck, the shivering boy pressed deeper into his alpha. Despite feeling smug, the alpha situated him in his arms, rumbling with purrs as he continued, “Baby, don’t you want to make your nest? All pretty and good for me?” 

Sukuna watched as Yuuji peeled himself from the alpha’s neck and scent gland, eyes glazed and shiny, cheeks rosey as he panted. The omega peered across the expanse that was Sukuna’s den, eyes zeroing in on the pile of blankets and pillows. Slowly, he nodded, turning to look back at his alpha with teary eyes. 

Cooing, the four-armed curse helped the boy down, keeping him steady as he caught his land legs once again. Trailing after him as Yuuji wobbled towards the pile of blankets, Sukuna practically drank in his scent, shivering as he watched the light dribbling of slick following his omega. Oh how wet he was for him already.. Gods, he couldn’t wait to help himself to that fountain of youth. 

Stopping a few steps back, the alpha watched as his omega scurried about, busying himself with preparing a new nest. He knew that omegas preferred to have their nests built before their heats started, and belatedly, he worried if Yuuji had already had a nest built. 

Shaking himself from that immediate stupor, Sukuna crossed his arms. Allowing his deeply pleased and happy scent to freely soak the room, he watched with a grin as Yuuji paused to inhale, shuddering as he caught onto the alpha’s scent. He continued to watch as his omega built up the walls of the nest, pillows piled in the middle, he dully realized the omega was putting the pillows there in lieu of a mattress. 

“Oh Yuuji..” The alpha breathed, grinning widely. If he didn’t know how important nests were to his omega, he would already have him in it, wrecking the nest as he fucked him. 

Turning to face his alpha, the little omega let out little chirps and whimpers of affirmation. Clearly seeking the alpha’s approval, Sukuna approached the nest slowly. Yuuji was sat in the middle of it, and with pride, he realized the nest was large enough for his new- old? - form. A deeply satisfied rumble filled the space as the curse stopped just outside the nest, peering down at it.

“It’s perfect Yuuji.” His coo of approval seemed to please his omega, as Yuuji beamed, all teeth, up at Sukuna. Unable to stop the affectionate smile crossing his lips, he gently reached out a hand to pet at the strawberry blonde. The omega leaned into it heavily, purring happily as the hand basically smothered his entire head. Shakily using both hands, he wrapped his hands around the alpha’s monstrous wrist, tugging the alpha into the nest. 

Stepping into it slowly, Sukuna inhaled deeply, full body shuddering as the full scent of Yuuji’s heat flooded his lungs. 

Cocks giving an interested twitch, he easily gathered his omega into his arms. Rumbling happily, he nuzzled his way into the boy’s neck, cooing as the omega happily bared his neck in full. Oh silly brat.. His fangs itched to bite and chew his way into the boy’s neck.

Ignoring the dark desire, Sukuna sucked on the scent gland on the side of his neck, hands wandering across the omega’s body. The curse easily ripped his clothes off, leaving Yuuji bare to him. Grinning as he pulled back, the alpha looked over his body, eyes soaking up all of what he could.

Yuuji was flushed from head to toe, chest heaving as he took deep breaths. Eyes were half lidded as he looked up at the alpha, pupils blown wide. His tongue was hanging out lewdly, the pink tip tempting. His legs, however, were still squeezed together, hiding his cock and hole from sight. 

Scowling a little at this, Sukuna gripped the omega’s chin and brought their lips together for a kiss as one of his hands slipped downwards, towards the boy’s center. 

He sucked his way into the boy’s mouth, nipping at his lips as he drew moans and whimpers from deep in the omega’s lungs. Shifting Yuuji’s position on his lap, he felt the boy’s slick slide against his kimono pants. Grinning into the kiss, he used his wandering hand to pry the omega’s legs apart. Humming gently at how the omega didn’t even fight back, a large finger trailed up the length of the boy’s small cock.

Pulling away to peer down at it, Sukuna grinned maliciously as he watched heavy drops of pre-cum roll down the tip of his cock. Pressing a nailed finger to it, he gently rocked the tip back and forth. Ignoring his omega’s petulant sobs and moans, he slid the finger down the underside of the cocklet, towards the source of his omega’s slick.

Scowling as his hand was cut short by his own thigh, Sukuna huffed a little. He had to do some more shifting around.

“Baby, I’m going to lay you on your back, okay?” He cooed, nosing the omega’s face. By the gods he cried so pretty… Watching as Yuuji nodded, he shifted the boy off his thigh and onto his back. Sliding his hands up his thighs, the alpha cooed and praised him, pressing his hands into his knees and puuuushing upwards, bringing the omega’s knees up to his chest. 

Glancing down at his cock, pussy and hole-

Pussy?

Pausing, the alpha glanced down again, throat going dry at the sight. He’s bedded many an omega before. Female and males. None have had both before. The curse ruminated over this for about two seconds before he dipped down, nearly drooling as he nosed at the bottom of the omega’s little cock.

“So pretty..” He cooed, inhaling the rich scent of his omega’s slick. “You really were made for me baby.. Such a good, perfect cocksleeve of an omega.” Grinning, Sukuna slipped his tongue out to kitten lick the boy’s perfect little clit, nestled just under the omega’s little cock. 

“Alpha!” Yuuji cried out, hips jerking at the sensation. Grinning, Sukuna used another hand to settle on the boy’s abdomen, pinning him in place. The omega whimpered and whined, hips twitching as he tried to chase the feeling. “Alpha, please !” He sobbed, fingers reaching out for the king of curse’s hair. 

Purring, Sukuna glanced back down to watch the omega’s twin holes wink, clenching around nothing as slick sluggishly dripped out of both of the holes. He vaguely remembered Yuuji once telling him he was a dominant omega. He wondered if this is what he had meant by that?

“Easy omega… Alpha will take care of you.” He cooed, using his fourth hand’s thumb to spread his pussy lips, shuddering as he caught a fresh wave of pheromones and slick gushed out. Oh perfect omega…

Dipping down, he slowly dragged the tip of his tongue up from his hole to the top of his pussy, moaning at the taste of his omega’s slick. It tasted like fresh, ripe peaches straight from the tree, crushed together and mixed with the highest quality soju and whiskey. Without a second thought, the alpha quickly dove in, for once glad their size difference made eating him out in both holes easier then it should have. 

Bathing in the sound of Yuuji’s screams and moans, the alpha kept him pinned as he tried to jerk into the feeling. His cock left abandoned, bouncing headlessly against his stomach, the alpha began his feast. 

Nose bumping against the omega’s clit as he wiggled his tongue into the boy’s hot pussy, he hummed deeply, fingers digging into the boy’s silky thighs. Sukuna thought dully, that he would be more then happy to die in between these thighs. Death by drowning. Cooing, he dragged his thumb down to the omega’s hole, curiously poking at the entrance with a single finger.

“Ah! Ah!” Yuuji’s cries broke his concentration, causing Sukuna to peek up at him. Smirking, he dove in deeper with his tongue, wiggling it into any space he could get it into. Slick was practically pouring down his throat at this rate, and he used this to his advantage as he slowly slipped a finger into the boy’s hole, shivering at how easily it accepted his finger. 

“Good boy..” He whispered into the boy’s pussy, withdrawing his tongue to spit on it, watching as the omega’s pussy practically sucked it in, clenching and winking around nothing, as if mourning the loss of the alpha’s tongue. The alpha in question let out a little hiss, spitting on his omega’s pussy again, only to watch his spit slip back into the omega. “ Fuck …” 

“Alphaa…” Yuuji whimpered, cock twitching and hips jerking as he tried to seek out some stimulation. Deciding to stop torturing his poor omega anymore, he dove back in. Starting to pump his finger, the alpha continued his feast with his omega’s pussy, happily gorging himself on the slick he was provided. Fuck , he really could just live out the rest of his days between these thighs. Curling the finger in the omega’s other hole, he grinned into the pussy as Yuuji cried out. Clearly he had found the right spot. 

Running his finger up and down it, the alpha listened and watched the omega’s reactions, happily drinking and drowning in slick as he continued to eat out the boy. Cooing encouragements, Sukuna was belatedly surprised that Yuuji hasn’t cum yet. He came so quickly and easily last time, and that was from humping the floor like a puppy in heat..

Peering up at him, the curse felt a jolt run down his spine. Gods above, the omega looked so fucked out… Eyes wide open, staring unseeingly into the ceiling above, tits flushed and red despite having garnered no attention. His whole body was a bright red, and the boy’s mouth was hanging open, tongue rolling out as he drooled all over himself. Grinning to himself, the alpha continued his ministrations, using the weight and size of his tongue to prep the omega as he eased another finger, slowly, into the boy’s hole. The slick certainly helped, as well as his heat. However, Sukuna was larger then average, and, well…

Closing his eyes, the curse huffed into the boy’s heat, fully burying his face into him. He was ignoring the boy’s cock for a reason, despite the ever present chirps and whimpers, the omega whining for some sort of attention on it. He was blessed with a pussy. He was going to learn to cum from it. 

Deciding he had enough, the alpha nosed the boy’s clit once more, pleased to find it trembling beneath him. Pulling away, he gently blew on it, smirking at the soft shriek that left his omega. Oh, he was so close…

“Gonna cum baby? Gonna come for me like a good omega?” Sukuna cooed, his hot breath fanning out over the boy’s pussy. Sliding his tongue over his lips and chin, he gathered as much slick off his face as he could, continuing to finger the boy’s other hole. “You deserve it baby.. Coming to find me. Letting me know your heat was here. Such a good omega.. Gonna fuck you so good, fill you and breed you with my pups..” 

Watching as the omega’s pussy, and feeling , the boy’s hole clench around him, he grinned stupidly. Who knew the brat was so weak to a little dirty talk. This was nothing compared to the things he used to say…

“You can cum anytime baby.. Good omegas get to cum as much as their alpha wants them too, okay? You can cum, can’t you?” The curse whispered, dragging his tongue up the boy’s pussy, before ending his sentence with a gentle, soft nip at the boy’s clit. Grinning wickedly as the omega jerked, sobbing as his pussy fluttered around nothing. 

Humming, mostly to himself, the alpha dipped back down to his spread, happily nipping and licking his way into the boy’s core. He wasn’t too sure how long he kept at it, and how many times his omega eventually came, but he knew he slowly worked his way up to four fingers in his omega. In both holes. 

Pulling back, the alpha leaned back on his knees as he panted, catching his breath. Slick dripped down his front, soaking the front of his pants and certainly the nest they were currently spread out in. 

Taking in the sight before him, Sukuna felt his cocks twitch even more, desperate to dip into the omega and drive him crazy. Yuuji let out little whimpers and whines, gasping and heaving for breath as his hips jerked, chasing the feeling of an orgasm always on the tip of his cock. 

Speaking of. Sukuna was quite proud to admit it. Yuuji hasn’t come from his cock once. Poor thing had to be so pent up, but only bad omegas could come from their cocks. This was supposed to be him giving Yuuji praise…

“Good omega…” Sukuna cooed, drawing a hand up and down the omega’s thighs, trying to catch his own breath. Thank god he had practically endless stamina to draw on.. “You’re doing so good baby.. Think you’re ready for the main course?”

Hands already drifting down to his own pants, Yuuji’s fucked out eyes flicked towards his alpha. Besides that, the only response he got from the omega was a jerk of the hips, and a heavy spike in his pheromones, reeling the alpha in for a deep kiss.

Oh, how ready for the main course he was .

Chapter Text

Hands spreading out over Yuuji’s body, Sukuna met the boy’s purrs with his own rumbles. Grinning, all teeth, he nudged his way into the strawberry blonde’s neck, drinking in the scent of his heat. By the gods, he would make the boy wear a collar at all times, so no one else could smell him. He pulled his omega into his body with his upper hands, spreading the boy’s legs across his lower chest so his stomach mouth could continue his mistrations on the boy’s lower body.

His lower hands reluctantly left his brat’s body to work on his pants. He was painfully hard, cocks straining against their tight confounds. As his large fingers fumbled over the ribbon holding his hakama up, he eventually grew frustrated. His hands were shaking far too much with excitement and anticipation to do this properly.

Resorting to base tactics, he used his own curse to slice his pants off- freeing his cocks in the process. They bobbed at their freedom, straining against their own weight. Although his omega, moaning and shrieking with delight- distracted as he could be, could not see the action, he felt it. His cockheads, mostly the top one, brushed against the boy’s lower back, surely searing their sheer size into his skin.

“Aaallphhhaaa….” Yuuji cried, fat tears rolling down his cheeks. Sukuna happily licked them up, cooing softly at him as he slowly peeled the sweat sticky boy off of him. He splayed him out in his nest, managing to keep the boy still long enough to drink in the sight.

The rose haired omega, surrounded by plush blankets and pressed against the sweat and slick soaked pillows. His pupils blown and unfocused, cheeks red with fever and want. His neck and chest rose rapidly, tits and nipples flush. His stomach, disappointingly flat. Soon, his cocks would bulge through it and distend it with all his cum. He would see to it proper. Chuffing with satisfaction, Sukuna towered over his omega, nosing into his neck as he cooed, aware the brat would barely hear him over his high.

“Relax for me princess.. We’re getting to the main course.”

Using his lower arms to grip his cocks, the alpha slowly prodded both holes with a separate cock. A true blessing his omega was. He had always hated leaving one cock unoccupied in the past, often leading to having two omegas hanging off him at a time. This time, he truly could focus solely on this simpering, begging mess beneath him.

Yuuji’s hips bucked and he cried, trying to force the alpha’s cocks into him before he was ready. Shushing him, Sukuna used one upper hand to start plucking at the omega’s nipples- abandoned as they had been.

He whimpered and sobbed, arms flinging themselves over Sukuna’s shoulders to scratch desperately at his back. A mistake that would've gotten him killed should they be in the past. A mistake the alpha happily accepted, slowly pressing each cockhead into his omega. Yuuji’s eyes rolled into the back of his head at the pressure. Truly, the omega would’ve never had felt anything like this before. He doubted he’d filled one hole before, let alone both at the same time.

In faux kindness, Sukuna went slow, careful to not go too deep too fast. He knew that Yuuj couldn’t take all of him, his cocks were like those they belonged too. Monstrous. He’d never measured, never cared too. But he’d never met a human who could take all of one, let alone both.

As if though signalling the end, he felt his cocks press against something hard- in both holes. The end of where he was permitted, clearly. Humming, Sukuna leaned back slowly, to see how much his omega had taken. Surprise took over him as he gazed at a little over three fourths of his cocks, buried deep within his omega. Pride swelled within his chest. Pride for his omega- and proof that in time, he could train his brat to take all of him. One day- a day far in the future.

“Look at that princess….” The alpha chuffed happily, a finger trailing down to test the tautness of his omega’s holes. He teased his clit on the way down, feeling the omega spasm around him. A brief moan cut through Sukuna’s throat, his lower teeth clenching in an attempt to keep his head on straight.

Gently pressing against the flesh holding his cocks in place, Sukuna found what he thought. The skin was pulled tight, stretching to its limits around his cocks. Surely more then it would've had he had only the one.

Leaning back down to his omega, Sukuna started sucking and kissing his neck, distracting his omega as he began to cautiously move his lower body, lest he damage the one person he’d found that was made for him. However, no pain seemed to grace Yuuji’s heat-addled face, and no pain was found in the way his fierce omega clawed at his back, begging him to move faster, harder, quicker.

“In time, princess…” Sukuna purred, nibbling at the loose skin around Yuuji’s neck. His lower set of eyes flicked towards the side of Yuuji’s neck, where the inflamed gland could barely be seen. Instinct was thrumming in his veins- instinct to bite, to mark. To marr.

Closing both sets of eyes, Sukuna began to carefully pick up the pace. His cocks dragged deliciously against his omega’s walls. He was still barely moving, worried that if he moved too fast or too hard, his cocks would break through the barriers keeping his omega’s inner organs safe. While a delicious thought, he planned on keeping this one alive for more than one passion filled night.

“Alphaaaaa….” Yuuji pleaded, digging his claws into Sukuna’s shoulders. The brat’s hips kicked, desperate for faster stimulation. Tutting softly, a free hand reached up to pet at Yuuji’s hair. Words would no longer work on the brat, he was too far gone. Actions were the best way to get through to his heat drunk pet.

Nipping at any exposed skin he could get too, Sukuna, very carefully, began to pick up the pace. He was still going agonizingly slow for himself, but the improved pace seemed to placate his omega for the time being. And besides- slow sex wasn’t a sin. It was nice from time to time, even if everything in his bones was screaming to take it fast and hard, uncaring if his omega broke in the process. Inhaling deep against his neck, Sukuna’s eyes rolled back as he inhaled pure pheromones. He could get drunk off the scent of his omega alone- no sake could ever compare again. Perhaps when this was over, he’d commission specialty sake, to taste exactly like his omega. He knew it was possible. He’d seen what his brat had researched when he thought Sukuna hadn’t been watching.

Corralling his omega into his arms, Sukuna eventually sat up. Both moaned at the feeling of Yuuji sinking just that ever deeper onto Sukuna’s cocks. The omega’s head rolled, unsupported as Sukuna used all his arms to hold him secure as he jerked his hips up.

Yuuji cried out- not in pain but pure unadulterated pleasure. The omega’s hips jumped in response, desperately attempting to sink further. Join deeper with his alpha.

Soon enough, both were mumbling nonsense, Sukuna whispering sweet nothings about how he’d breed his omega well, Yuuji slurring through many words for how he was feeling. The alpha could barely understand him, but the point was brought across. Eventually, Yuuji’s words turned into moans and whines as Sukuna’s pace picked up.

He’d properly assessed if his omega could handle a faster pace, and he was pleased to note no matter how hard he seemed to go, Yuuji felt no pain. If that was true after his heat passed, that remained to be seen.

Glancing down, Sukuna grinned morbidly at the sight. The position he’d switched them too made it all too apparent, Sukuna’s cocks bulged obscenely from the boy’s stomach. They twitched and receded with every thrust, and temptation couldn’t escape from his grasp. Grabbing Yuuji’s arm, he led it down to his stomach.

“Squeeze.” Was his one whispered command- more of a plea then anything. Despite the heat frying his brain, Yuuji got the point. Using his shaky, weak hand, the omega felt the bulges on his stomach, and gently squeezed. It wasn’t tight pressure by any means, but the added stimulation made them both moan- animal and guttural.

It seemed this all was too much for his omega, and the boy’s body began to spasm. His back arched, pressing his cock tight against his alpha’s stomach. His orgasm seemed to be taking over his whole body, before Sukuna noticed a significant pressure in the boy’s pussy.

Curious, Sukuna reluctantly paused. He peeled the still orgasming boy away from him, before curiously pulling his top cock out of the boy’s hole. The result was almost instantaneous. The second his cock head slipped from the hole, it bobbed and slapped against the boy’s clit- and that seemed to be enough.

Liquid spurted from the boy’s pussy, violent in its nature. His stomach mouth opened on instinct to drink up all he could, as Sukuna watched in amazement. Perhaps too amazed, as he didn’t seem to notice his own knots swelling, deep within Yuuji’s body. He noticed almost too late, and in a desperate bid, managed to shove his free cock back into the brat’s body before his knots swelled, locking them in place.

However, his cock was no plug. Yuuji continued to squirt this mysterious liquid, his body spasming and jerking with every movement. Sukuna did everything he could to keep his eyes from rolling into the back of his head as his omega squeezed deliciously around his cocks, his cum flooding both holes of his omega.

A sick part of him wondered if Yuuji had two wombs for two holes. Something to discover another day, perhaps.

Yuuji’s hips kicked, his cock bobbing desperately between their bodies as Yuuji’s cries went silent. His mouth agape, but no sound escaped him. Narrowing his eyes in morbid curiosity, Sukuna’s hand went to the ever growing bulge on his omega’s stomach. He gently pressed it, watching in amazed satisfaction as the liquid- not urine, by the smell and colour, spilled out in another strong wave.

Worry in the back of his mind for his omega’s potential dehydration, one of Sukuna’s hands slowly trailed down. His lower mouth was still drinking in all it could, and his hand gently caressed his omega’s cock. The only attention he’d given it all evening.

Yuuji finally whimpered, hips kicking at the feeling. Sukuna pressed a single nail against the tip, before his cock began spilling. It was the normal cum the alpha had expected, sticky and white. However, it seemed as it the boy wouldn’t stop spilling. His cock bobbed desperately with the pressure, releasing hours of built up cum.

Sukuna’s eyes couldn’t help but widen in wonder, watching as his miracle of an omega came from two orifices at once. And both seemed to have no plans in stopping. He grinned a sick grin, kicking his hips forward. His knot was still snug in place, there was little movement he could do, but it was encouragement for his omega.

Keep going. The movements said. And keep going Yuuji did.

Over the course of several more hours, Sukuna’s knots delated and reinflated multiple times. Yuuji continued to spill in the same manners multiple times. His body knew what he wanted, long after the omega had passed out- and Sukuna provided. He used his omega’s body in ways he knew the omega would love when he woke. Yuuji drifted in and out of consciousness after that, crying for his alpha and more when he woke.

When he was no longer in heat, the alpha knew there was much to discuss. But for now? He’d enjoy his offering.

Chapter Text

The first thing that brought him to life was the smell. A thick cloud of sin, sex and smoke hung over his head, a wildfire of heat beneath him. His body was sore and heavy, and if he focused hard enough he was sure he could smell blood coming off his skin.

A hand, hazy and weak in his half sleep state, wandered up towards the back of his neck. His fingers rubbed gently at the unmarred skin, a frown immediately appearing on his sleep laden face. 

Blearily opening his eyes, Yuuji took in his surroundings. He could see high walls with no ceiling in sight. There were pillars holding up the walls, and there was an underlining scent of pure cursed energy swimming through the haze of sex and smoke. His eyes drifted to his closer surroundings. He could see the walls of a plush nest surrounding him, the scents worryingly dull. There was only his and…

Flicking his eyes down, the peach haired boy scowled. Him .

Sitting up, eyesight temporarily going dark as blood rushed to his brain, the omega narrowed his eyes angrily.

“Sukuna.” He barked, reaching out to pinch the delicate skin of the alpha’s neck. The significantly larger alpha grumbled in his sleep, an arm reaching out and grabbing the omega by the waist, pulling him down as he rolled over. 

Yuuji let out embarrassingly happy chirps, internally pleased to have his alpha in his nest, their scents swimming through the air, soaking anything they’d come in contact with.

“ Sukuna .” The omega hissed, wiggling an arm free to pinch and pull the alpha’s skin.

“Shut up and go to sleep.” Sukuna chuffed, blearily opening his lower eyes to peer at his omega. Part of him was proud to have worn his alpha out so much. The rest of him was irritated . 

“Sukuna. Wake up.” Yuuji growled, allowing his irritation to seep into his scent. This only seemed to egg the curse on, the alpha pulling him closer. He probably thought Yuuji was angry at coming out of heat and finding himself in his arms. But that was far from the truth. 

Pushing his arms against Sukuna’s chest, the omega wiggled as far as he could to get away from the alpha while staying in the nest. The curse let out a chuff of disappointment, finally opening his eyes to leer at his omega. Crossing his arms, Yuuji glared at him for a few moments, before speaking angrily,

“Why.” Not a question, a statement. He wanted to know .

“Why what?” Sukuna drawled, eventually hauling his massive body into a more upright position. He narrowed his eyes to slits, a smug grin worming its way onto his face. He didn’t even know why the omega was upset!

“Why…” Suddenly feeling shy, Yuuji uncrossed his arms to press a hand to the back of his neck, gnawing on his lip before continuing, “Why didn’t you bite me?”

Sukuna’s eyes widened, sitting up fully. He crossed his upper arms, setting the lower on his knees. He leaned closer to his omega, observing him like he couldn’t believe what was in front of him. The alpha sniffed the air, looking for any sign of deception. 

“...Did… Did you want me to bite you?” Sukuna offered, eyes flicking towards all the bite marks littering the omega’s body. 

“Of course!” Yuuji protested, throwing his hands up in exasperation. “Why else would I have gone to you in my heat!” His own words caused him to flush, heat rising to his face. He cast his gaze to the ground, turning to picking at his cuticles. Admitting it outloud was embarrassing…

Sukuna chortled, a soft chuckle turning into a full blown laugh. Yuuji blushed harder, jerking his head up. The alpha was holding his sides as he laughed, a full body shake taking him over. 

“Stop laughing!” The omega protested, kicking his feet as he rolled to his back. His hands covered his face, whimpers escaping his throat at his own embarrassment. He startled when he felt one of Sukuna’s hands grab at his wrist, gently tugging him closer.

“Easy there little pup.” He hummed, corralling the younger onto his lap. Holding him close, the alpha pet his thighs as he released calming scents, burying his nose into Yuuji’s neck. “I didn’t want to kill you.”

Oh, that’s right. Mating marks could only be given with full consent. If an omega was marked by an alpha without wanting to be marked, the omega would reject it. The rejection would take a toll on their body and possibly result in the omega’s death.

“...I wouldn’t have come to you had I not been prepared for it…. Or wanted it.” The omega whispered that last part, still too embarrassed to say it aloud. He knew that he should hate Sukuna, for everything he’d done. That he should loathe the alpha with every fiber of his being. But he couldn’t, he just couldn’t.

Sukuna hummed in response, a grin gracing his lips. He could feel it on his skin. He felt soft kisses pressed to his skin.

“I suppose that’s true… I wasn’t using my right head to think, I suppose.” Yuuji cringed at the bad, dirty joke his alpha spoke aloud. Jokingly slapping at one of the hands pressed against his thigh, the omega leaned into his alpha. 

“So…” The peach haired boy hummed softly, peering back at the alpha, “Are you gonna get on with it?” Sukuna met his gaze, a triumphant grin crossing his lips. Yuuji was hardly given any time to react before fangs connected his scent gland, and white invaded his senses.

Pure bliss. It was pure bliss.

And he would get to experience it with his mate .
