Revenge is best served 10 inches up the rectum

Please don't read this

Please, I don't know enough about JJK - I barely paid attention in Season 1 and have an interest in just Geto for Season 2, so I know fuck all about what they actually do in their classes. Just let this be a private boarding school AU where Gojo is a teacher and Megumi is his student - I can't be asked to insert any cursed techniques into their sex scenes.

Megumi was too tired to process what time of the day it was, the glare of the sunlight slipping through the cracks in the door being bright enough for his eyes to go bleary. He was feeling groggy all day - maybe something to do with the strange food Gojo had convinced him, along with the other first years, to eat. Still, with limbs like lead he makes his way to the door, ceasing the grumbles from under his breath.

"Who is it," he mumbles, letting in more light to whoever had knocked at his door in the first place. He'd half expected it to be Itadori, but was startled by the large, long and lean body propped against the door.

"Hey Megumi!" Gojo chirps with his stupid smile, that same cunningness seeping into his voice. "I was instructed to check up on you!"

Megumi couldn't deal with the sunlight, nor the gross excitement emanating from Gojo. He attempts to close the door but to no avail, the imprudent shoe wedging it wide open. 

"What were you doing anyway?" he asks, inviting himself in like the arrogant man Megumi knew him to be. Besides, he could never go up against his impressive strength.

"Sleeping off whatever you fed me last night," he mutters spitefully, to which he received that same grin in return. "Think you can leave?"

He could have sworn Gojo smirked as he walked further into his room, towards the bed, dishevelled from his own deep slumber. He's too comfortable, stretching his legs out in a man spread, the tip of his Adam's apple bobbing up and down. He cuts his thoughts off before he could think any further.

"What are you doing," he sneers, stalking closer to the bedside. Like the strike of a snake, his arm is grabbed in a vice-like grip, and he is dragged onto the bed, his legs draping off the side.

Gojo moistens his lips with the tip of his tongue. "See, Megumi, I was supposed to be going straight home and have a little Gojo time, but the principle called, talking about suspicions on you skipping out on school today. And to see you absolutely fine whilst I'm pent up, well-"

"Just get to the point."

"If you insist," Gojo chuckles, his face getting closer. "I need to jack off."

Megumi froze up, and had no time to react as the fly unzips, followed by the button, and Gojo moves to reveal the prominent bulge hidden by the bagginess of his trousers. A mere tug on the waistline of his boxers, and the impressive length sprung out, girthy and stiff with a defined arch, and a twitching vein that ran along its underside. It was huge - much bigger than the other dicks in Jujutsu Tech that Megumi had seen, through changing and when in the bathroom with them. At least, with the students.

But he couldn't stop looking, entranced but also very disturbed - was this not his teacher?

Gojo lounges back a little further, capturing the thick member in his hand, and starts moving it in a languid motion. His breath becomes slightly hitched, lolling his head back a little, his smile trembling at the corners.

It twitches, only getting longer, and Megumi had to stop and consider whether he should kick Gojo out of his room, or leave and give him privacy. But why was it still growing, even until this second?! If Megumi brought his dick out to compare in size, it would pale in comparison.
