Yuuji smelt like thunder moments before a storm. Satoru was the unsuspecting boat caught in a swell, about to be capsized.

Yet, Satoru wasn't afraid. He wasn't scared. His core throbbed and his muscles ached with want.

More than anything else in the world, Satoru wanted this.

He's so hot, bathing Satoru in suffocating heat and the scent rolling off of him was different. This wasn't the usual meadowgrass Satoru was used to. The calm breeze against a cliff face.

There's something dark in his usually kind eyes. Something feral.

Something monstrous.

It makes Satoru's knees buckle and he barely has time to crash to the floor before Yuuji is crowding over him, fangs bared, eyes glazed over, drool dripping from his lips.

He's leaking down his legs before he's even made it halfway to the door, underwear practically soaked. And he doesn't even make it TO the door before it's being wrenched open and Satoru's sees ALPHA Yuuji.

teacher is already well and truly in mind numbing rut mode.

With the last of his own sanity, Satoru breaks in. Quietly locks the door behind, turns off the alarm, and creeps his way to the bedroom where the thick scent of a hungry, needy, desperate alpha in rut is strong.

He takes heat suppresants. If there's one thing he knows no alpha can resist, it's an omega in heat. All Satoru has to do is take the suppresants until the day of Yuuji's rut. Then he stops the meds. It takes a day for his own heat to creep back in and by then, he knows his

So he does the next thing he knows best: he follows his teacher home and watches him. Tracks his ruts. Keeps careful track of the days, making sure they all match up.

He makes copies of Yuuji's keys, learns the code to his alarm system.

And makes a PLAN.

He tries and tries again. He even tries bribing Yuuji, wears a skirt sans underwear, accidentally bends over in front him to show him his slick stained hole.

But nothing works.

And it's driving Satoru insane.

He's never wanted an alpha so bad.

Satoru's never, NEVER, been rejected before.

It makes him want Yuuji all the more.

He chases. He teases. He pulls out all of the tricks in the books, even lets himself linger by the alpha a little too close to his own heat.

But Yuuji never bites.

He pushes Satoru away and tells him to get going, his friends are probably waiting for him.

Enter omega Satoru who's always had whatever alpha he's wanted. He's never cared too much about finding "the one" because he simply wants to satisfy his needs.

Until in walks his new teacher, Itadori Yuuji, and Satoru knows he wants.

#YuuGo

This made me think of 28 year old alpha Yuuji who's terrified of how strong he is out of rut. When he's in rut? There's holes in his walls, broken furniture, impossibilities.

It's why he's always locked himself away for his ruts and resolutely spent them alone.

Uncle Yuuji who promises to see him again soon, their cousin's getting married next month and Yuuji wouldn't miss it, or Sukuna, for the world.

Uncle Yuuji who grunts into his ear about how wonderfully tight Sukuna is, how his body remembers Yuuji like they were born to be.

Uncle Yuuji who leaves bruises in places Sukuna can hide them, bites at his shoulders, and cums twice before he finally pulls out.

Uncle Yuuji who sneaks into Sukuna's room at night, whispering against his mouth how good he is, how sweet he is, stripping Sukuna from the waist down.

Uncle Yuuji who never quite uses enough lube and never quite stretches Sukuna enough.

Uncle Yuuji who forces his tongue into Sukuna's mouth and tells him to shush if he doesn't want everyone to think he's a slut who asked for this.

Uncle Yuuji who coaxes Sukuna to his knees, telling him to be a good nephew now and Yuuji will make sure it doesn't hurt later.
