It didn’t take a genius to know that Itadori Yuuji would present as an alpha. Satoru could tell from his muscular build and outgoing personality alone. And, of course, the King of Curses had been an alpha. Satoru wasn’t sure if Sukuna being an alpha would mean Yuuji would be one as well or if curses even had that much influence over a vessel.
Either way, Yuuji had yet to present and the higher ups were… nervous to say the least. They worried about Yuuji’s ability to contain Sukuna during his first rut, and they argued that Sukuna could come out to cause havoc (what kind of havoc they were implying, they refused to say). The higher ups wanted something done about it, regardless, and since Yuuji was Satoru’s problem, according to Yaga, the responsibility fell to him.
Not that he minded.
Satoru would rather those old farts leave him to do what he thought was best rather than have to run every little thing past the geriatric bunch. He figured they’d find his plan of action… a little unorthodox.
For the next few months, Satoru watched Yuuji closely for any signs that he’d be presenting soon. Until finally, Satoru smelled Yuuji from across a field during training and he knew the time had come.
There was no doubt in his mind that Yuuji would be an alpha, even if it would make his life a whole lot easier if Yuuji presented otherwise, so he put his plan into motion.
No one would question if Yuuji disappeared for a few days. Everyone was bound to assume that he was dealing with his “first time.”
Satoru got everything set up in the underground halls of Jujutsu Tech. Then he waited for nightfall. The nice thing about Yuuji was that he followed a pretty consistent routine.
At ten thirty at night, Satoru appeared in Yuuji’s bedroom, where he found Yuuji fast asleep. The smell wafted off the sleeping boy and Satoru steeled himself to handle his body. Yuuji smelt like embers and pine, with the faintest hint of citrus. It was nice. Satoru wondered if it would remain that way once he was done.
Holding Yuuji’s sleeping body, still bundled in his comforter, Satoru transported them to the room he’d set up within the undergrounds of the school. He monitored Yuuji’s heartbeat while he got situated, just in case Yuuji woke up. Satoru wasn’t looking for any surprises.
The room was similar to the one Yuuji had been locked in when he was first brought to Jujutsu Tech, but Satoru tried to make it a little more homey. Instead of Yuuji being tied to a chair, Satoru strapped him into a snug straitjacket with talismans sewn over the sleeves and chest. He doubted Yuuji would try to stand much but if he did Satoru could easily overpower him. In place of the chair, Satoru had settled Yuuji onto a pile of his own blankets and shirts and pillows.
Satoru wasn’t sure if he wanted Yuuji’s first rut to go smoothly or if it would be more fun to execute his own plan.
Yuuji woke up slowly.
The smell of ember and pine intensified, flowing through the room in heavy waves.
Buckles rattled as Yuuji struggled to lift himself up into a sitting position.
“… Gojo..?”
Satoru smirked. “I’m here, Yuuji. How are you feeling?” he said casually, leaning against the wall on the opposite side of the room.
Yuuji smacked his lips, weakly tugging against the jacket. “Feel weird…” he muttered. Yuuji shifted, taking deep breaths as he dragged his eyes up and down Satoru’s body.
“You know what’s happening, Yuuji?”
Yuuji bobbed his head up and down.
“I’m presenting.”
“That’s right. We’ll get you suppressants after this, but we need to see how you handle things just this once.”
Again, Yuuji bobbed his head. The suppressive atmosphere of the room really seemed to be doing a number on Yuuji. It was almost cute.
“Sukuna…” Yuuji murmured.
Satoru smiled. “That’s right, we don’t know how he’ll react to you presenting as an alpha. It’s just a precaution.”
Yuuji lied back down on the pile, flopping like a fish as he tried to get comfortable. It reminded Satoru of babysitting a drunk friend, though Satoru was typically the drunk friend needing babysitting. Shoko could handle her liquor. Yuuji went in and out of sleep for a while and Satoru thought the higher ups had worried for nothing. He put in all that work just to have front row seats to a horny teenager’s erection.
After a few hours, the air shifted. Instead of drowning in ember and pine, the overwhelming scent of incense and burnt wood filled the room. It was more assaulting than Yuuji’s smell, like it was trying to choke out Yuuji and Satoru’s scents. Satoru pushed off the wall to stand up straight.
“What do you think you’re doing, Six Eyes?” Sukuna spat.
Satoru smiled wickedly. He could commence the plan. “What are you doing out, Sukuna?” he practically sang. “Don’t you know that this is an important time for Yuuji?” He resisted the urge to jump right in. It made sense to wait, get more information, give Yuuji a chance to resurface.
Sukuna sneered at him from his spot beneath the blankets. He was trying to seem intimidating despite being wrapped up like a newborn. “He can barely open his eyes in this atmosphere.”
Satoru shrugged. “Doesn’t mean you have to come out.” Was Yuuji weakened by the talismans or was his rut too much to handle, allowing Sukuna to come out? Satoru needed to figure out what was happening exactly.
Sukuna shifted in the straitjacket, a flash of disgust crossing his face. He flexed his arms, testing the durability of the jacket. Satoru could tell there wasn’t any struggle for control. It was just Sukuna with him now.
“You were an alpha, weren’t you?” Satoru asked, cocking his head. “At least when you were human?”
Sukuna continued to fuss with the jacket. He grit his teeth and growled low in his throat,
Satoru took a step closer. A sense of giddy excitement filled him, a stirring in his gut that flared the closer he got to Sukuna.
“Is something wrong? You seem a little flustered.” Satoru couldn’t stop smiling.
“Fuck off,” Sukuna hissed.
Satoru took another step closer. His own scent began to seep into the room, patchouli and fresh fruit. He hoped Sukuna wouldn’t notice, despite how obvious it was. Satoru wanted his plan to go off as smoothly as possible and he had a feeling if Sukuna realized he’d become much more difficult.
“It’s probably been well over a thousand years,” Satoru thought aloud. “The guys’ upstairs are a bit worried Yuuji won’t be able to hold you back.” His heartbeat picked up. He focused on his breathing. “So you’ll both ride it out down here.”
It was becoming harder and harder to hold back. Satoru had to put his hands behind his back to hide their shaking. He wanted to jump on top of Sukuna. He’d never fucked another alpha.
Sukuna pulled his lips back into a vicious sneer. He eyed Satoru. “What are you doing here, then?” he snapped.
Satoru could tell Sukuna was getting to be on edge. He writhed around on the sheets, sweat matting his hair to his forehead. Satoru found himself staring at Sukuna’s throat, at his swollen scent gland. His entire throat seemed to throb.
Satoru wanted to sink his teeth in.
“I’m here to determine liability,” Satoru said, carefully monitoring his tone. He struggled to hold himself together. He’d fucked plenty of omegas and his fair share of betas but never claimed any of them.
Never fucked an alpha. Never claimed one.
Until now, it would seem.
Sukuna just continued to glare. His throat was the cutest shade of pink, his pulse visibly jumping. He had his guard up. It was smart of him, obviously, considering what Satoru had in store for him.
“You said Yuuji was feeling too loopy to come out, right? What about you?”
Satoru was practically right on top of Sukuna now. He was drowning in Sukuna’s smell and he wanted nothing more than to take a fistful of his hair and fuck him into the pillows. The higher ups wouldn’t care. He was basically doing what they asked. Wouldn’t they want the King of Curses’ vessel, and by extension Sukuna himself, to be claimed by the strongest sorcerer in modern times? It made sense. Satoru was doing everyone a favor.
It made sense, he kept telling himself.
It made perfect sense.
“Know your place, Six Eyes,” Sukuna snarled.
Satoru smirked. “You must feel awkward at least. I mean, you’re going through your first rut.” He crouched down, resisting the urge to reach out and touch Sukuna’s bare leg. Aside from the straitjacket, Sukuna was completely nude.
“This is not my first—“ Sukuna grunted in frustration and shot out a leg, trying to kick Satoru.
But Satoru caught his leg. The physical contact made Satoru see fireworks. He couldn’t hold back anymore..
Satoru used the leg in his hand to his advantage and threw Sukuna onto his stomach, digging his fist into Sukuna’s scalp. Any noise Sukuna made was muffled by the mound of blankets and pillows. He knew he was also manhandling Yuuji as well but he couldn’t help himself. The temptation was overwhelming and all he could think about was pounding into Sukuna and making him his bitch. He didn’t just want to fuck him, he wanted to own him. He wanted to be able to say that he not only bitched the King of Curses, he claimed him. Sukuna would bore his mark on his neck.
Sukuna, though, wasn’t going to make things easy for him. He furiously bucked his hips and thrashed around, jerking his bound arms against the restraints desperately. From shoved in a pillow, he howled. He must’ve known what was going to happen. He’d probably done this himself back in his hayday. And, as Sukuna admitted, Yuuji was too weak to take the reins back.
Satoru grabbed Sukuna’s hip, his nails digging crescent shaped cuts into the flesh. “Be a good boy, okay,” he cooed. The air hung around them like a thick curtain. Their scents mingled together and Satoru felt a spike of adrenaline shoot through his veins.
It made sense.
“Be good for me. Don’t fight too much. You’ve barely presented so I’ll make sure it feels good.”
Satoru knew he was babbling but he couldn’t help it.
Sitting in the pheromone filled room had gotten him so hard and he felt a surge of excitement seeing Sukuna’s exposed hole. Since Yuuji had only just presented and was in his first rut, he still had both, his penis was a little more defined though.
Satoru would change that.
It just made sense.
Hastily tugging his pants down, Satoru lined up his throbbing member with Sukuna’s hole. It wouldn’t be the same as bitching a fully developed alpha, but the King of Curses was a good conquest. He kept Sukuna’s face buried in a pillow, his frantic cursing and growls made Satoru’s dick twitch.
“Be a good boy,” Satoru said with a heavy exhale. He pressed himself to Sukuna’s pussy and slowly started pushing into his warmth. “You feel so good. Fuck, you’re going to be an amazing bitch.”
Sukuna howled, thrashing around desperately. He was so warm and tight. It was so different from a typical omega. Satoru had to press himself into Sukuna instead of sliding in with a slick heat. There wasn’t anything Sukuna could do. Given the suppressive nature of the room and Yuuji’s weakened state, he wouldn’t fair against Satoru even if he wasn’t in a straitjacket.
Still keeping a fist in Sukuna’s hair, Satoru pulled Sukuna’s head back. Sukuna gasped for breath. His eyes were wide and wild, and he gnashed his teeth.
“Fuck you, Six Eyes,” Sukuna nearly shrieked. “You will live to regret this, I swear it!” He tried to rear his head back to bite Satoru but he was placated with a rough tug at his scalp. “What will you do once this brat wakes up? How will you explain what you’ve done to his body, huh?”
Satoru snapped his hips into Sukuna’s backside, pushing himself deeper into his hole. “I’ll figure it out,” he grunted through clenched teeth. He didn’t care if he wasn’t thinking straight. All he could focus on was Sukuna’s tight pussy, imagining how good it would feel all slicked up and sloppy.
He wondered if Sukuna’s slick would taste differently from Yuuji’s. He’d have to do some experimenting once they were properly bitched.
Lost in thought, Satoru hadn’t realized just how quickly he’d started fucking Sukuna, slapping against his bare ass with his hand still gripping tightly on Sukuna’s hair. He’d pulled Sukuna’s head so far back all he could do was pant and struggle, his Adam's apple bobbing.
The sight was actually pretty endearing.
“Yuuji’s got some decent life skills. He can cook and clean and shit, but I think I’ll reserve the fucking for you.” Satoru let out a breathy laugh.
Sukuna bucked his hips. He made a strangled cry from the back of his throat and Satoru practically purred.
“Oh, did you want to do the cooking and cleaning too? We have to make sure Yuuji feels included too, it is his body after all.”
Still inside Sukuna, Satoru whirled him around onto his back and pinned him against the makeshift nest. On his knees, Satoru propped Sukuna’s fumbling legs on his hips, lifting his lower half up. He wanted to press in deeper. He pictured Sukuna, the King of Curses, carrying his pups. Getting all round from pregnancy and needing Satoru to rub his feet. He wondered if Sukuna would get clingy if he was with child, giving into that base need to be protected by his alpha.
By Satoru.
Satoru pounded into Sukuna, gathering him up in his arms and burying his nose in Sukuna’s neck. He could tell he was close, his knot was forming.
Sukuna seemed incoherent. He gasped and spammed, kicking his legs out desperately trying to get away from Satoru.
“You’re mine,” Satoru panted. “You’re mine.” Saliva pooled in Satoru’s mouth. Logically, he knew he shouldn’t mark Sukuna. It was still Yuuji’s body and he’d have to be responsible for caring for a bitched alpha during heats. He might even have to properly claim Yuuji and keep him around. And then there was the matter of executing Yuuji once he’d collected all of Sukuna’s fingers.
Pressed to Sukuna’s neck, Satoru took in his scent. He smelled sweeter than before.
Satoru couldn't stop himself. Fucking ruthlessly into Sukuna’s pussy, Satoru bit down on his scent gland, sinking his teeth in until he tasted blood. Sukuna screamed. He fought back with a renewed vigor but Satoru held him down effortlessly.
Satoru clutched a fistful of Sukuna’s hair, teeth still clamped down on Sukuna’s neck, and came. His knot swelled inside of Sukuna and he collapsed on top of him with a low groan.
For a long while, Satoru just listened to them both breathing. Sukuna’s heart pounded against Satoru’s body. It was almost a nice moment, Satoru thought of them together, riding out Sukuna’s heat in Satoru’s apartment. No talismans or restraints or threats from the higher ups. Just the two of them. It felt strangely right.
