Enemies.

That's how people knew them. Something in their past made them hate each other desperately and they never talked to each other normally unless it was banter or physical violence.

Sukuna was the champion on the boxing team. Won round after round and didn't back down once. He wasn't one to take losing easily.

People were bipolar about him. Sometimes he was quiet and didn't do much. Sometimes a fuse was blown and he would blow up on a teacher or a random student.

He had a habit of breaking the school punching bag and he (begrudgingly) always paid for it.

There was someone always on his mind though.

Satoru Gojo.

That damn cocky brat.

The man was always smarter than him, stronger in some fucking way that made Sukuna's blood boil.

Any time Sukuna saw him, there was an URGE to break the man's glasses and face simultaneously, but he never did, because he wasn't trying to get suspended from the boxing team.

Satoru wasn't much of a difference.

He hated Sukuna in such a way that he would rather die than ever interact with the man again.

What he hated about himself, was that his body still missed his ex. And he didn't fucking like it.

He NEVER gave into these urges and often focused more on his damn studies rather than anything about himself.

Satoru was the smartest person in the district and always got perfect scores. It was almost effortless at times.

He was on the mathematics team and instead of people being the love of his life. He LOVED calculus, he loved numbers.

But he knew, there was still a tiny stupid spark left for someone in his heart.

And that person hated his guts.

---

Metal blasted in the man's ears and he kept them on throughout class.

Sukuna messed with the callouses on his fingers and picked at them as his headphones were on one ear and hanging off the other.

It was another boring day in school, and he couldn't do anything about it.

He COULD just walk out, but he was on his last warning from his coach, and he wasn't trying to fail again.

But there was a familiar voice that was ringing in his damn ear that he could never escape.

Satoru's voice.

Always answering questions with such precise words, it made a vein throb in his forehead.

Yap, yap, yappity, yap.

Sukuna made a mocking signal with his hands and let out a heavy breath of air before feeling a pencil connect with the back of his head.

That was strike one.

He turned his head and rubbed the spot where the pencil hit him.

There was a suspicious looking Satoru looking away and whistling innocently while the man wrote down some useless notes.

An audible huff escaped his throat before class ended.

Sukuna walked out and felt a hard tug on his hair.

Strike fucking two.

He turned back before seeing familiar white hair speed past him like a cheetah.

If that man messed with him one more time. He might throw a fist or two.

It was the afternoon and Sukuna has just finished training.

It was particularly grueling due to his own emotions and whatever the fuck his coach was saying.

And for some reason, he couldn't cool down.

Both emotionally and physically.

It felt like it was 100 degrees fahrenheit rather than a chill 80.

He let out a heavy exhale as he walked to the bathroom and washed his face with cold water in the sink.

He heard a sudden shuffle and a high pitched whine.

He froze.

He's heard that whine before.

Many times actually.

Before anything went down.

He slowly stood back up and listened closer.

Another whine.

He slowly stepped closer to the stall before pressing his hand against the door.

Why is it unlocked-?

Everything in his body stopped once he opened the door.

He saw a perfectly pink pussy being spread wide open by two slender fingers while Gojo was bent over the toilet seat.

The folds were pleasantly swollen and the man's clit was peeking out the more he fingered himself.

Satoru was sopping wet. Leaking onto the tile floor as the man desperately tried to hold in his muffled little whines and moans while biting his shirt.

A slow devious grin arose on Sukuna's face and he cleared his throat loudly, "Am I interrupting something . . .?"

Satoru froze before he stood up almost immediately, his glasses lopsided and his face beat red, "S-Ryomen-?!"

"Keep going I was enjoying the view."

Satoru pulled his fingers out before Sukuna grabbed his wrist and brought the soaked fingers to his lips. "I could stuff that pretty cunt and make you scream like I used to."

Satoru's breath hitched and all the old feelings he buried were peeking out again, and it wasn't exactly unpleasant.

"Ryomen. What are you-"

"Use that big brain of yours. You understand every word perfectly."

Satoru swallowed and looking down at his swollen cunt before he let out a shaky breath. "J-just this once." He muttered, bending over slightly before feeling his chest pressed against the stall wall.

A surprised yelp escaped his mouth before Sukuna wrapped his hand around the man's lips, "Once I'm in, I'm not slowing down."

Satoru felt pleasantly displeased with the sudden situation before he felt two fucking cocks press against both of his holes.

He has almost forgotten Sukuna had two of them, and he was about to be stuffed full.

Satoru bit Sukuna's fingers before feeling himself be completely filled up in one smooth motion.

A loud whine left his throat before the sound of skin against skin reached his ears.

Both holes were being stretched so wide it made Satoru feel dizzy. He missed this feeling. He missed it like he needed it.

Sukuna kept slamming his hips into Satoru's and let his teeth reach the man's neck before they sunk into his skin.

They didn't hear the bathroom door open and they didn't realize that someone else was here with them.

"S-Sukuna-! Hah!"

"Quiet brat."
