Work Text:
Gojo Satoru and Fushiguro Megumi had a rather unusual relationship. It started as nothing more than Gojo being his benefactor and saving him from a life as a Zenin and slowly developed into more. Which was one way of saying that Megumi was only about eleven when his soon-to-be Sensei started making inappropriate advances towards him.
Megumi of course was fully aware of just how weird this was for Gojo to be doing. It wasn’t that he particularly cared though, it felt way better than touching himself, as much as he hated to admit it (and the physical closeness was really nice at times). He still wished more than anything that the man would keep his mouth shut as he did it. Sometimes he blabbered throughout the sex, to which Megumi couldn’t even talk back because over the years, Gojo had learned all the little ways to make his stoic façade melt into a tiny puddle. Making him entirely unable to respond to anything the man said to him.
To say that Gojo loved teasing Megumi was an understatement, it was practically his lifeblood. Aside from Kiyotaka, Megumi was always the most fun out of everyone to tease and annoy. Each of his little reactions was priceless to him.
It was really a very usual night. The two of them were in Gojo’s bedroom. The only thing different tonight was that earlier that day, Megumi had completed his very first solo mission as a Sorcerer. He’d even done quite well at it. All of his studying and training had paid off.
“Did you do so well today cause I promised you a reward?” Gojo teased him. Megumi rolled his eyes. “What even is it?” he inquired for the third time today. He was already all too familiar with Gojo’s games and aware that any and all joyful anticipation may just turn out to have all been for nothing, so he wasn’t very excited anyway.
“Alright… I’ll tell you.” He sighed dramatically. He spread his legs on his bed before he spoke, “I want you to top me tonight, Megumi.”, Megumi’s heart skipped a beat. He didn’t know if he’d heard it correctly. There was no way he wasn’t pulling his leg right now. They’d never seriously discussed switching positions.
“You… what?”, Megumi stammered. Not quite wanting to believe that it wasn’t another one of his strange pranks. “It’s only fair I let you try it out, isn’t it?”, Megumi still didn’t want to believe it, but he certainly wasn’t going to turn down an offer like this. His dick twitched in his pants at the thought of getting to do this.
Megumi kneeled on the bed, he was still mostly dressed. “I never knew you liked…”, not quite sure what to say. “It’s been a while. I enjoy it sometimes.”, Megumi hadn’t really taken him for that kind of guy. He always seemed to have way too much fun being the one doing the work rather than being on the receiving end.
Both of them didn’t waste too much time, took their shirts off and french kissed. He liked the feeling of Gojo’s naked chest against his. He pulled down his Sensei’s pants while the latter did the same with Megumi’s. Today the boy was more enthusiastic than usual. He could not hide that he was really excited about this. While he’d already taken it up the ass quite a few times, he’d never gotten the chance to be on top himself. He was eager to finally make Gojo shut up.
He groped at his Sensei’s ass, wanting to get started already. Gojo chuckled, “Eager, aren’t you?” and he absolutely was. Almost impatient. Megumi reached for the lube, already knowing where it was, then pulled down the man’s underwear.
He was going through the foreplay very quickly, but Gojo didn’t complain even once, so he just kept going. Megumi threw his Sensei’s underwear to the side while he covered his fingers in lube. Surprisingly enough, he’d never done any fingering himself. Gojo’s fingers were always bigger and better than his, so he felt no need to.
But as soon as he actually touched his rim, he realized that he was already quite loose and lubed up. Megumi froze for a second and looked at Gojo. “Did you already prepare yourself?” He asked, confused. Gojo wordlessly nodded and smiled, Megumi couldn’t see his eyes through the blindfold, but he knew full well what kind of look he was giving. “Then why didn’t you tell me?”, “I thought I’d let you find out for yourself.”, that made no sense to the boy, but he didn’t question it because nothing would ever come from that.
Megumi was about to pull down his already straining boxers, eager to get down to business, but Gojo stopped him in his tracks. “Wait, you need something to fuck me with.” And moved aside to rummage in his bedside drawer. Megumi was kneeling, thoroughly confused. He had “something” right there?
Gojo then pulled out what looked like a strange harness and a dildo, Megumi looked at him, utterly confused. “Why would I…”, “Come on Megumi, you didn’t seriously expect me to let you have all the fun just yet, did you?”, Gojo stated. “You wouldn’t even know where to start if I let you fuck me like that.”, Gojo briefly pulled out the boy’s dick from his underpants, only to put the strap right next to it, as a sort of comparison. It was very much bigger than him, concerningly so. Megumi’s face (and hard-on) fell at that. He was no longer in the mood for sex. He just wanted to go.
The boy grabbed his clothes and made a move to wordlessly get off the bed. But Gojo grabbed his arm before he could get off. “Don’t be like that. If you can fuck me properly tonight. I’ll let you use your actual dick next time.”, Megumi wasn’t moving away anymore, but he also still wasn’t quite convinced. His Sensei loved tricking people, but he wasn’t the kind of person to really break a promise. The issue was that he usually found a lot of wiggle room, which technically-but-not-really broke the promise he’d made.
“When is that ‘next time’ going to be?” Megumi asked him, freeing himself from his grip. Gojo seemed to actually think about it for a few seconds. “Friday night, next week, I’ve got my day off then.”, he said. Megumi looked at him. He seemed to be a bit more open to the idea now, albeit still disappointed.
While the two of them put everything together and on Megumi, he obviously still had his doubts about “next week”, someone like Gojo would always find some fucking wiggle room in any promises that he made. He’d learned that over the years he’d spent with him.
The boy felt quite degraded knowing he’d be using a measly piece of plastic tonight in place of his actual cock. So much for the brief excitement he’d felt just a while ago, but then again, he’d already known that there had to be some kind of catch. It was to be expected with the blindfolded bastard.
Gojo positioned himself with his arms and head on the bed and his ass in the air while Megumi put some more lube on “himself”. He still had his underwear on, and the strap gave him a little bit of a sensation, but not much. He thought about how his underwear would most definitely be ruined after tonight and how underwhelming this would probably feel as he got into position on his knees.
The strap caught on Gojo’s rim, but Megumi didn’t seem to want to go inside of him just yet. “Next week I get to do whatever I want to, for as long as I want to, and I get to cum inside. Got that?”, Gojo grinned smugly and nodded, “Sure. If you do well.” Wanting him to get on with it already.
With the (highly necessary) clarification out of the way, Megumi FINALLY pushed inside of Gojo. Gojo hissed, presumably from the stretch. Megumi took it slowly, only because he wasn’t too eager on proving Gojo’s point about him not being good. Right now, Megumi only hoped it would be over soon so that he could leave. It had already been a long day for him, and this was only another chore.
He pulled out nearly wholly, only to push right back inside. He watched his Sensei clench around “him”. He tried not to focus on it and kept moving, trying to find a good rhythm. He somewhat knew what to do. Go slow at first, try your best to find a rhythm, pay attention to reactions and the rest will come naturally.
“Right there!” Gojo exclaimed, Megumi tried to do his best to hit the same spot again, if he did that, hopefully it would be over quicker. It was quite strange to watch his Sensei moaning like that underneath him but surprisingly enough, he didn’t dislike it. He wanted to see more.
“Fuck, that’s good…” Gojo moaned underneath him, he once again really wished that he could claim the same. “Cmon Megumi, go faster. Or are you tired already?” He teased again. Megumi sped up and didn’t respond to him. His patience for today was wearing thinner than thin. He wasn’t too exhausted from the mission but what was supposed to be leisure for him had been turned into nothing more than another chore. He hoped that his Sensei was finally done mocking him and would shut his damn mouth.
“Aren’t you- ah grateful?”, Megumi considerably slowed down. “For what?” He countered with another question. “That I’m teaching you so effectively. You wouldn’t be lasting this long with that pathetic little thing you’ve got.”, something in the boy suddenly snapped. He wasn’t going to let that sit this time.
Megumi completely halted and leaned down towards his ear, “You’re a fucking asshole. You know that?”, Gojo grinned and opened his mouth to talk back. But before he could get a single word out, Megumi began to fuck him rough and hard, knocking the air right out of his Sensei’s lungs. So much for all those mocking remarks.
The boy roughly gripped Gojo’s hair. He kept cussing and moaning, far louder than before, for once he seemed unable to articulate himself at all. It was a sight that only gave him the vigor to keep going. “Nothing to say now, huh?”, he said to his Sensei through gritted teeth. He didn’t answer that. Having the upper hand felt incredibly satisfying. Having the Strongest at his mercy like that.
He noticed his Sensei trying to sneak a hand of his downwards, but he was faster. Held it tightly right next to his head. After all, how was he supposed to learn how to make his Sensei feel good if he was just going to help himself?
Deep down, Megumi obviously knew that if Gojo really wanted him gone, he could quite literally expel him from his body by activating his technique within a fraction of a second, but to have this man writhing underneath him like this was something he never knew he needed. He was in love with the feeling of being in control over the one who constantly mocked and made a fool out of him. His dick flopping and leaking uselessly while he got plowed.
Megumi only stopped when Gojo came onto the mattress. He was a man of many talents, lasting particularly long was not one of them. He had a dopey smile plastered on his face and his ass collapsed onto the bed. The boy watched his stretched hole gaping in emptiness. He knew that technically, his job was done. He could take that shitty thing off, wash and go to sleep, knowing that in a week he’d truly get to fuck his Sensei however he wanted. But he didn’t feel quite satisfied with what he saw just yet.
Gojo tried to roll off and free himself from his student’s grip, but said student only pinned him to the bed by the shoulders, the boy looked at him with a stern look in his eyes. “I thought we were using today to practice, Gojo-Sensei. I don’t think I’ve quite got it yet.”, Gojo looked at him through the slightly tear-soaked blindfold, awfully turned on and only a little bit scared. It was a look that seemed to ask: “Did I create a monster?”
Megumi pushed back inside of him easily, filling him up all over again. Gojo could only sigh at the feeling of being full again. And so, the whole process repeated.
-- 40 minutes later --
Megumi pulled out of Gojo, finally exhausted himself. He laid down next to him to catch his breath for a good while. He tried to pull off the harness but to no avail. He’d like to have it gone and to never wear it again. There was no need to after all.
After a whole lot of fumbling (and perhaps damaging it in the process), he finally succeeded and carelessly threw it aside. “Never using this again.” He grumbled. Surprisingly enough, Gojo had nothing to say to that. It was strange, but welcome. Aside from the sound of both of them breathing it was completely quiet. Silence.
He rested for a few minutes. The longer he did, the filthier he felt. He really needed to wash up. After all, he hadn’t showered all day and the slight mess in his boxers only added to it. He sat up, stretched, then stood up. Gojo was still strangely quiet.
Megumi briefly shook him. “Are you still up?”, he slightly nodded, “Need anything?”, “Some water.” He said, uncharacteristically quietly. Megumi wondered if he’d actually broken him but figured that he’d be back to normal by tomorrow.
He took a very quick shower and came back half-dressed with two glasses of water. One for each of them. Gojo was still lying in bed completely naked in his own filth. Megumi got into bed next to him and tucked both of them in.
The boy leaned over, “Friday night. Next week?”, Gojo nodded. Still at a complete loss for words. Megumi laid down to sleep. He finally had something to really look forward to.
