Yuuji had just turned 13 and just started experiencing all the horrible changes in him, his sweat glands started producing and he felt like entered the burning gates of hell. He always though he would be a beta right in the middle, perfect, but life decided he would be better as a alpha.
Ever since that he smelled like cinnamon sugar and a rainy forest , a perfect combo he told himself over and over,but out of the few things HE HATED about being an alpha is if he applied to much pressure on objects they would break. He hated that, he almost broke one of his grandpa's old antiques, but he stopped himself just in time.
He only had a few ruts througout his years, which was always odd he thought, he read things about alphas getting ruts weekly and always thought himself as odd one out.
He noticed ever since he turned 18 his ruts increased, they became a ton more painful, he would be stuck in his room for days on end taking cold showers constantly. Or sometimes take a few cigarettes, and chatted with Sukuna he didn't like to chat with the king of curses but he was bored sometimes in his ruts.

Sukuna thought he couldn't get heats in yuujis body , but he turned out to be wrong, the heats were worse, not having access to anything that could help him it felt like he was in hell. Cursed energy would flow out him like high pressured tap spaying at all sides. Sukuna still had his domain though he made a comfy bit in his domain, he created pillows blankets, mostly anything comfy.
He built a small best, just big enough for him, in this form to fit in, he curled up shielding himself with blankets, as he curled up his body felt unbelievably hot, so unbelievably hot. He felt a slight trace of slick coming out his ass, he would clean it later, he just needed to rest the now.

Yuuji was suddenly transported into Sukunas domain, a warm but ,cold place he gazed around the place looking for any signs of Sukunas presence. He noticed a small bit in the left hand corner of his domain, it was covered head to toe in blankets , pillows, all the sorts. He tip toed over being as quiet as he possibly could ever be, as he reached the blanket fortress. He smelt a strong smell of what Sukuna smelt like, but mixed with vanilla and lemon, it smelt amazing, like better than anything he had ever smelt before.
He gazed over Sukunas small body, he looked odd, and why was he in a pillow fortress? Unless, wait no, the king of curses phftt- can't be a Omega right? RIGHT?.
Usually Omega's get smaller when in heat, loose a few pounds, height drops a bit, and there faces look more cute.
Yuuji thought for a second his rut was burning him alive, if Sukuna was in heat that would be perfect! , now all he needed was a green card.
Sukuna felt a presence near him, his eyes snapped open, but he had no fight in himself, his heat drained all his strength leaving him weak, and horny. He saw that pink haired boy in front of himself, he gripped yuujis muscle packed arm and gave him a slow nod before bringing yuuji down to his knees and fell in his arms.
Sukuna could smell yuujis strong pheromones, a mix of cinnamon sugar and s freshly rained forest.
"Please- yuuji"
"Fuck me. "
Yuuji didn't think twice, he needed someone to release his rut into, glad he got this golden opportunity, he wanted to savour, every, single, bit.
"I won't go easy on you"
Yuuji later took Sukunas robe of him, revealing his small frame, and he noticed the slickness between his legs, he would deal with that later.
He also noticed that look of desperation in Sukunas eyes he was warm, warmer than him, he started infiltrating his tounge into Sukunas mouth, cupping the back of his head while one hand was around his lower back.
"Mphh-"
As yuuji pulled away from the king of curses, he saw his dishevelled appearance, his hair was slightly ruffled, more on the messy side.
Yuujis rut became more painful, he needed to be inside of sukunas ass, and now, fuck that about savouring this.
Yuuji turned sukuna on his backside, revealing his plump ass, he didn't want to hurt sukuna no matter how much he wanted to be inside of him. He placed one finger in, slowly moving his finger inside and out the hole. He could hear sukunas faint moans of pleasure, he slowly added another finger keeping a slow pace. Preparing for what was about to come.
He noticed that sukuna was faintly trembling, he blushed at the sight of his body trembling, he looked so cute in that moment. He entered a third finger, this time he quickend his pace a bit, he felt that sukuna was getting close, so he lifted him up on his lap, still keeping 3 fingers in him. And slowly jerked his cock of, after a minute he felt sukuna release himself.
"You okay? "
He could still hear sukunas panting after a moment, wondering if he should stop and let him rest he held him, he slowly took the 3 fingers he had entered previously and held him on his lap. Wrapping his arms around his torso, waiting for him to say what to do next.
"Just - keep going, y-you pu_pussy"
Sukuna felt yuujis gentle embrace, he gave him time to breathe and was taking it slow, unlike all the other alphas he noticed in his lifetime. Itadori was maybe better of a person that he thought.
Did he just call me a pussy? Oh ill show him whose the pussy. He thought to himself.
Itadori rolled his eyes, and he slowly took of his sweatpants then his pants,to reveal his cock, it was big, had a few veins and the tip was swelling a deep pink. Sukunas eyes drifted back to see how big yuuji was.
His eyes widened in shock.Well, not what he expected bigger than his for sure, but he wouldn't say that out loud obviously. But damn, how was that even going to fit?
"That won't fit. "
"Ill make it fit, just watch"
Yuuji teased his ass by putting tip in and out, just to annoy the small Omega.
"J-just put it in. " sukuna said in an irritated tone
"If you say soo" yuuji spoke in a cocky voice.
Yuuji put a quarter worth of the cock in him, he heard sukuna let out a moan, he looked at sukunas face, and saw a few tears run down his cheek.
,"Hey, are u okay,- I didn't mean to hurt you-"
"Keep -" (deep breath) "going."
He put around half of his cock in, and sukuna was gripping the sheets, he slid out then in, halfway again he repeated this process till sukuna came again.
"Are you ready? "
Sukuna nodded his head in agreement,
Yuuji slowly and steadily, managed to fit his whole cock in that tight ass, somehow. He let out a small sigh of relief, and noticed sukuna mumbling something, he brought his head down to his.
"Gosh, your so small" sukuna said in a small voice, barely audible.
SMALL? he thought to himself, he was bigger than sukuna. How dare he call him small, he decided to destroy that ass, that tight, tight, ass.
He suddenly pushed sukuna back, on the nest, his back was arched and his ass in the air. He entered him in a fast motion. Way faster than before, he heard sukuna let out a moan, or cry he couldn't tell.
Sukuna only said he was small to make him angry, this what was exactly he wanted, a angry yuuji, he never saw yuuji angry before. Only when his friends grew hurt, but this one was all for himself.
He felt yuuji speeding up, and, wait did he just incorporate a back flash in me? Fuck, that felt good he thought .
Sukuna let out moans of pleasure, yuuji felt like his balls were going to burst if he didn't cum, he suddenly pulled out of sukuna. And busted right on his back, leaving a hot. sticky mixture dripping down him.
Yuuji removed his shirt, revealing his glistening abs, he wondered to himself why he didn't take it off before, oh well.
He entered back in sukuna, speeding up with every new thrust, he kept adding back flashes in, which brought sukuna to the edge, once again.
Sukuna let out another load, his sticky mixture mixed with the blankets, and yuuji sped up.
_ __ ___ ____ _____ ______ _______ ______ _____ ____ ___ __ _
"S-slow down" sukuna almost screamed
So he did, then sped right back up,
"F-fuck, mphh- "
Yuuji swiftly captured sukunas lips in a kiss, so strong he felt he couldn't breathe.
After a few seconds he let him go, to breathe as yuuji kept a fast pace, before he pulled out.
Sukunas body had , had enough, sukuna used his remaining strength to fall backwards into yuujis arms. Yuuji still wanted sukuna, so instead he just started nibbling his ear. While wrapping his arms around him.
But he wanted sukuna to clean off first, he rembered that in one of his conversations with sukuna he mentionef that he bathed in hot springs. But where were those? He looked around the domain looking for any signs of a hot springs, he just assumed the pool things were a hot spring.
He was right, he carried sukuna in his arms, he felt like not that heavy but heavy at the same time. He placed his smallish body into the pool, he joined in after him, it actually did feel pretty warm.
But he still was slightly hungry for the king of curses, his sweet scent, so he brought the king of curses over on his lap, he brought his head down and started licking and teasing his nipples.
"Hmph! -"
Sukuna let out slow moans, while yuuji touched and teased his nipples, he sucked on one, and rubbed his fingers with the other one. After yuuji had lifted his head back up, he saw sukunas eyes desperate despite everything, he put his hands around his back.
And both started sharing a long, passionate kiss, there tounges collided like a Pacific ocean mixing with an Atlantic. Both pulled away from the kiss, sweating, and a faint line of drool dripping down yuujis chin.
Yuuji wanted to leave one last mark, he kissed all of sukunas neck, leaving faint hickeys and kiss marks, sukuna wanted yuuji, all for himself.
He decided to say one line that would change both of their life's.
"M-mark me"
"But-"
"I don't care just do it"
Yuuji thought for a second then thought, fuck it .
Yuuji bit his teeth into sukunas shoulder,
Then sukuna bit down on his, both left a faint gold glow then dissapeared. Both passed out , sukunas head rest along yuujis chest. While yuujis lay a top of his head.
Everyone who was in campus felt it that day, the bond of an alpha claiming an Omega, shoko deducted a emergency medical checkup on all the students. She wanted to make sure no one had done it out of pure spite, and she just wanted to lecture someone.
Yuuji woke up and realized that sukuna was right beside him. IN HIS BED, somehow he came here from his domain, his robe was now on, but yuuji had no clothes, he was just bare.
(Knock knock)
"Yuujiiiiiiiiiii~"
"Hey Gojo,! "He shouted from his room, he was rushing to put something on,
He managed to put his clothes on just in time, so senseni didn't barge in and see sukuna in his bed.
" so uhh- what do you need!? "
"Shoko just wants to check who got marked, "
"Oh okay! "
Yuuji started thinking of ways to stall, but before he knew it, he was already at shokos office.
"Ill wait right outside for youu! "
Yuuji nodded and headed in the office, the florescencet lights hit him much more than he thought, Shoko motioned him to come and sit on the chair . He did as asked and Shoko looked at his right shoulder, yuuji started sweating,.
"A-am I all clear to go now-? "
"Just let me check the other one- "
Fuck, Shoko was gonna catch him, red handed, he didn't even think, he sprinted out that room back to his dorm.
"Hey, come back! "
Gojo noticed yuuji , it looked like the fastest he had ran, oh well he thought to himself.
Shoko came out the room with a annoyed expression on her face,
" well its looks like we found are culprit. "
"Wait, he GOT MARKED?"
"Well why else would he run for his life? "
"Ohhhh okay"
