Work Text:
Class 1-A had thought that after three years at UA Iida might chill out a little. From day one, he had always been...well, Iida , but they thought that by their third year he would be a little more relaxed. But by the midpoint of their final year, Iida is still acting like fun and relaxation are words that don’t exist in his vocabulary.
Well, Sero is about to change that.
After a whole night of baking with Kaminari keeping watch outside of the dorm’s kitchenette, he now has a sliced batch of brownies. But not just any brownies. These are special brownies. Plus Ultra brownies. And the ‘Ultra’ is pot. A fuckton of it.
“You’re not going to, like, make him eat them, are you?” Kaminari asks as he arranges them on a plate.
“What? No, you fucking weirdo.” Sero has already had one (“for quality assurance purposes”), and he’s definitely feeling it. His edibles are not shit. Never have been, never will be. “I’m not trying to drug him.”
“Well, technically you are. You’re literally giving him magic brownies.”
“I’m not trying to secretly drug him! And you’re thinking mushrooms. Magic mushrooms. Special brownies.”
Kaminari puts his hands up like he’s surrendering. “Fine, you’re the drug boss here.”
“And the sex king. Don’t forget that.”
That makes Kaminari laugh. “Seriously?”
“Seriously?” he replies, mocking Kaminari’s voice. “What was that you were saying the other night?” Now he changes his volume to a moan. “‘Oh, Hanta! Eat my ass like breakfast, yeah!’ I think that was it.”
“Shut up! Oh my god, you’re so loud!” Kaminari is blushing through a thousand shades of red as he pushes at Sero. Okay, he shouldn’t mess around with him too much. He likes fucking Kaminari a lot, and the last thing he wants is for him to go cold on him.
“Sorry, sorry.” Sero puts down the plate of brownies so he can pull him into a kiss. “You’re okay with this, right? With me and Iida messing around?”
Kaminari nods. “Yeah, I’m sure. I mean, assuming you do. You haven’t even talked to him about it yet.”
“Dude. Come on. I’m the man. How is he going to say no to all this?”
Sero is fairly confident. He’s just a confident guy anyway, but also, it’s like… he can’t think of any reason Iida wouldn’t be down to mess around a bit. There’s been something there for a while now. Nothing spelled out, sure, but a vibe that Sero has gotten around him. Iida has always been hot, and he has had no problem checking him out, and then the handful of times Iida realized he was checking him out, he definitely didn’t stop him or seem not to like it.
It’s just been...something. A little spark.
Like one time when Sero was in the common room making out with Bakugou and Kirishima. They were on either side of him, and it was a mess of switching off, kissing three ways, mouthing at one another’s necks...and when Sero dropped his head back as Bakugou hauled Kirishima over his lap, he noticed Iida standing there in the doorway, watching.
To this day he would swear he saw his glasses fog up right before he turned and disappeared down the hall.
He knocks at his door, and at first there’s no response. Oh god. He didn’t even think Iida might leave the dorm to go to the library or get dragged out to the cafeteria with Uraraka or something. If he’s not here, Sero is going to end up eating all of these brownies and tripping balls until Monday morning (because, seriously, what other option would there be?!).
He’s relieved when Iida answers the door, straightening his glasses, hair just a little bit mussed. He’s in a tight white shirt and shorts, which is a very hot, casual look on him, and he seems a little...out of breath? “Hello, Sero. Is everything okay? Is there something I can help you with?”
“What? No, everything’s fine! I brought you some brownies!”
Iida blinks. “Oh. Why, thank you, that is thoughtful. What was the occasion?”
“It’s not, like, a special thing. I mean, it is, they’re ‘special brownies.’ But you’ve been so tense and shit for the past month since exams are coming up, so I thought they might help you chill.”
A smile crosses Iida’s face, and that makes Sero smile too. His happy marijuana serotonin is at a high right now, so the fact that Iida is happy feels even more like a good thing than it might usually. “Please, come in. That is so kind. I am not entirely sure how much sugar will make me ‘chill out’ this late, but it is the weekend, so…”
Fuck. There are even more books now than the first time Sero was in here during their little dorm tour, and there are just as many sets of glasses as well. He comes in and sits on the edge of Iida’s bed, and when Iida sits down next to him, he takes one of the brownies. “These look fantastic, Sero! I would even go so far as to say you and Sato should collaborate on some confections!”
“Ha! That’s a good idea!” ...holy shit, that’s a fantastic idea. There’s no way Sato doesn’t imbibe. They could make cookies, cakes, cupcakes, mochi...is that a thing? Pot mochi?
As Sero scans Iida’s room - the neatly-folded laundry that needs put away, a spread of perfectly-written notes on top of his dresser, a few cans of WD-40 - he finally gets to his desk. Specifically to his laptop. Specifically to what is on his desktop. It’s not like he’s trying to snoop! Does it even count as snooping, given that it’s across the room?
It doesn’t matter.
Because even at this distance, Sero knows a leather daddy when he sees one.
“Sero?”
His head snaps back to attention, even though he can feel blood rushing to his head (and elsewhere). “What, I wasn’t snooping!” It’s hard to tell exactly how long it’s been (what even is time?) but when Sero looks down at the plate, there are at least two more brownies missing. It hasn’t been that long, that’s for fucking sure. “Oh god.”
“Is there something...extra...special about these brownies?” Iida asks, still working on his third. He’s opening and closing his eyes slowly, off-rhythm.
“I mean, it’s the normal type of ‘special’ for special brownies.” That answer makes sense to Sero, but then… “You know what special brownies are, right?”
“Ones made with love?”
“Oh god.” Sero buries his face in his hands and shakes his head. Kaminari and his stupid joking, but he was so right. He’s drugged the class president and peeked at his spank bank. “Okay, so don’t freak out.”
Iida stops mid-chew, staring at him with eyes that are beginning to turn more black than the usual blue.
“They’re pot brownies. They have weed in them. That’s the special part.”
“...huh. I would have thought they would taste different.”
“Why?”
“Like herbal or something.” Iida peers down at the brownie. “You really ground the plant up…”
“That’s not how you...wait, you’re not mad?”
Iida stares into the middle distance for several seconds. He’s flexing his fingers, then seems to remember that he still has a brownie in one and finishes eating it. He doesn’t answer.
“...well?”
“Well what?”
“You’re not mad?!”
“No! Of course not! It is a little bit of a strange sensation. I can feel my hands, but not with my hands, if that makes sense.”
It makes perfect sense.
“If you think about it, the skin on our hands is like a glove for everything underneath, right? Our whole body is a glove. Like when you fill a latex glove with water but blood and muscle and bones...do you think if there was no skin our bodies would just sort of...run all over the floor?”
Oh my god, that is terrifying. What a terrifying thought. “I have...no idea. Hey, let’s talk about something else! What kind of music do you listen to? We should turn on some music and not talk about this anymore!”
“Good idea!” Iida gets up, which seems to be a monumental task on its own. It’s not quite like seeing a baby deer learn to walk...more like watching a fully-grown, stoned deer trying to cross a particularly large area of overgrowth. And then, when he actually gets to his computer, Iida just stands there for a long second. And then looks at Sero. And then at the computer. And then back at Sero. “...did you see this?”
Sero doesn’t know what to say. The fact of the matter is even if he hadn’t seen it, the amount of time it is taking Iida to navigate away from StrapMeDownAndFuckMe.gov would make it impossible not to see it now. “...no?”
“Oh god.” Iida still hasn’t actually minimized the screen. He’s just burying his face into his hands and turning to press his head into the wall like one of those ‘I’m so done’ cat meme pics that Kaminari sends Sero on a fairly regular basis. “You are judging my perversions as we speak...”
“What?! Iida, no!” Sero gets up and crosses the room (he’s much better at inebriated locomotion than Iida is) and puts comforting hands on his shoulders. “Dude, not at all! It’s fine! It’s...pretty hot, actually.”
“...really?”
Wow, Iida is not good at hiding his feelings like this. Not even slightly. In fact, his expression looks almost hopeful, and that...makes Sero have certain feelings too.
“Oh yeah. For sure. I mean, that’s not even really crazy shit, you know. I’m not kink-shaming, but I’ve gone into some search histories, okay, and...I’m just saying, liking some BDSM stuff is pretty tame.” Sero sort of wiggles his jaw from side to side a little before he builds up the courage to ask, “Soooo...are you into...giving or receiving?”
There goes Iida again into face-hiding, but he still mumbles through his fingers, “I have not exactly had the chance to experiment with a partner…”
“But if you did, would you be domming or subbing?”
A mental drum roll starts playing in Sero’s head, and he wonders if they would even be able to have this conversation if Iida weren’t relaxed. Poor guy’s blushing so hard he can see the red underneath his fingers. “...sub. Definitely.”
“Definitely, huh.”
“It is...so much pressure, being the class president and the most viable hero figure for my family since Tensei’s retirement and keeping good marks. I constantly feel like I am going to explode.” He finally looks up at Sero again, and when he does there is strain on his face. “I am so...tired.”
Fuck. Fuck, that sucks. Not that it’s a surprise. None of this is really new information. And yet, seeing Iida like this, opened up and honest about it instead of bottling it up...Sero feels bad for the guy. And turned on, yes, but he can feel both.
“I just want someone else to take care of me for a while so I can stop trying to take care of myself.”
“Even if, uh, taking care means ‘tying up and fucking senseless’?”
Iida’s eyes are so, so big. Wow. Sero is pretty sure he can actually see his whole face reflected in them. “In a...nice...way.”
Sero takes a deep breath. Here it is. He’s come to the fork in the road, and if he goes down one path, he’ll be heading into a point of no return. To this point, everyone he’s had this talk with has responded awesomely - it’s been all his best friends at UA, after all - but even if it doesn’t go badly, there’s no forgetting that you had a conversation with someone about wanting to have wild, kinky sex with them. That’s just going to be a permanent memory from here on out.
“Iida...why don’t you step into my office.”
“...This is my room,” Iida says with the stone-cold seriousness of a man blitzed beyond the current reality.
“Right, but...Iida, just...sit on the bed.”
They talk. A lot. They talk about things Iida likes, and things that he’s not so fond of. They talk about what he’s okay with and what he’s not okay with, the sorts of things he’s fantasized about, the kinks he’s willing to talk about. And Sero listens, and it’s a nice, long conversation so by the end of it he’s definitely sober and he definitely thinks that he can do this and do it really well. After all, the cosmos blessed him with a quirk that was made for bondage. It would be an affront not to use it.
So. This is happening. He’s going to fuck Iida Tenya.
Sero makes two quick visits: one to the bathroom and one to his room. The bathroom is to splash some water on his face, because although, yes, he had planned on potentially messing around with Iida, this is a step past that. The bedroom is for supplies.
When he comes back, Iida is standing at attention, just in his briefs and nothing else. Jesus, he is built like a brick shithouse. Sero does not get to appreciate that nearly enough. After a second, he nods at the bed. “Climb up on it.”
“You don’t want me on the floor...Sir?”
And there goes all the blood to Sero’s cock. Sir?! Already?! Fuck, he’s really going to have to perform to keep up with what Iida wants, huh? “Iida. Don’t forget there is one very important rule that good subs need to follow.” He doesn’t actually give Iida a chance to reply. Instead, he reaches up and gets a handful of blue-black hair, gripping it at the root and bringing it down to whisper, “You're not the one who gets to make the rules. Understood?”
Fuck. It’s like Iida starts floating. He can tell his knees are weak, and he groans at the rough treatment. “Y-yes, Sir.”
“Good. On the bed. Take your briefs off. Now.”
Iida scrambles to obey. His fingers do pause at the hem of his briefs, and Sero has some idea why. UA has been forward-thinking enough to keep all the guys together regardless of any differences between their bodies — who would have thought in a pre-quirk world that actually mattered to anyone? Be that as it may, though, Iida is a sweet, shy boy, and Sero would be lying if he said he wasn’t excited to play with that pussy of his.
His little cock is already hard, visible among his folds.
“There. That’s better.” Sero leans in to start kissing Iida, and immediately Iida melts into it, tipping his head back, making little breathy noises as Sero’s tongue flicks past his lips. That gets him shuddering, even whining a little, and that’s just kissing. “You good?” Sero asks with a grin.
Iida nods, cheeks flushed.
“Better enjoy it. You’re not going to get to keep using that mouth too long.”
The words alone make Iida moan. Fuck, is everything a turn-on for this guy?
Sero has him turn and put his forearms together behind his back. The tape dispenses from his elbows with a long, raspy sound, and he starts winding it around his arms, holding them together. A line of tape wraps around his whole body, pinning his biceps to the sides of his chest. He adds extra loops of tape around his armpits for support, rubbing his palms up to his neck. “How’s that? Not straining, is it?”
Iida shakes his head. His mouth is still open, panting, and Sero is pretty sure he’s checked out. Which is fine, of course, but he just needs to make sure he keeps an eye on him.
Sero’s used to being the guide through experiences. Drugs, sex, scary movies. He’s always up to be the guy who makes sure everybody is having a fun time.
He adds more tape around Iida’s torso, more for aesthetic - and for Iida’s sensation - than function, really: lines of it above and below his nipples so they stand out, a large ‘x’ over his stomach. He leaves his legs alone - he’s not sure how comfortable it would be with his engines pressed to his thighs, and revving them is their agreed ‘safeword’ - but still pulls him up to kneeling.
Sero smoothes his hands over the tape across Iida’s body. “Like it? It’s my own invention. Tape shibari. Not nearly as difficult and no rope burns.” Sero tips Iida face up, looking right into his eyes. “And it sticks more to itself than skin so...it’s a win all around, right?”
Iida nods.
“One last thing.” Sero dispenses another length of tape for the final touches, tapping Iida’s chin so he closes his mouth. He presses the tape over his lips and around the back of his neck, tucking one end before wrapping the other around. He makes two more thick passes, and Iida is taped up from chin to just under his nose, the tape pressing under his flushed cheeks.
“There we go,” Sero coos, thumbing the material flat, stroking over just where he can feel Iida’s bottom lip. He gives the spot a little peck. “You’re not going to be yelling at anyone about being tardy for a while, are you, Mr. President?”
Iida’s muscles flex under the tape, pulling, clearly trying to see just how trapped he is, and Sero lets him. He’s grown up with his quirk, and he’s very aware of just how powerful it is. Iida’s not going anywhere.
“Mm…” Air puffs out of Iida’s nose. It goes high and hard when Sero reaches down to toy with one of his nipples where it’s hard and standing between the strips of tape. “Mmm!!”
“You’ve got the best tits, Iida. Like, everybody loves talking about Bakugou’s, and they’re nice, yeah, but...fuck.” He rubs around the nub and then gives it a pinch, pulling at it and then letting go. When Iida squirms back, he gives him a little push so he falls on his back. Sero pauses only to pull off his underwear, and then he’s climbing up, perching on his middle. “Damn...it almost feels like I have way too many options...fuck your tits, fuck your ass, fuck your pussy. You’ve really been holding out on everyone, haven’t you?”
Iida squeezes his eyes shut as Sero’s long cock rubs through the little canal he’s created with the tape, and he pinches his nipples hard, making Iida let out a muffled, startled sound.
“If I had really thought about it, I could have gotten a ring gag so I could keep you quiet and get my cock in your mouth.” He keeps sliding his dick up until he’s slapping it lightly against Iida’s cheek. “You know what this means, right?”
Iida shakes his head, eyes huge as he looks up into Sero’s face.
“We’re just going to have to make sure we do this again.”
Sero’s always been pretty proud of his cock. It’s like a Goldilocks cock: not too big, not too small, not too girthy, not too shrimpy. Just right. And it’s perfect for just rubbing up and down Iida’s chest, all the way to his cheek where he leaves a little smear of pre on the tape strips.
“Oh fuck, this feels so good…”
He goes a bit faster, and Iida squirms under him, eyebrows knit. “Mmm…”
“Yeah, I know you love it too, you slut…”
“Mm!”
Sero chuckles and finally pulls back. “Okay, okay, you’re not getting enough attention, I can tell.” He slides until Iida is forced to keep his legs open to accommodate him settling between them, and he reaches over to pick up the item he got from his room. Somehow Iida’s eyes get even wider at the sight of the giant vibrator wand.
“Ever played with one of these?” Sero asks, dropping the head of the wand into his palm like it’s a bat he’s going to clobber someone with. “Mina turned me on - heh - to these. They are fantastic, but it’s a… ‘with great power comes great responsibility’ sort of toy.”
He turns it on, and the entire thing shakes in his hand.
“Too bad I’m not really great at being responsible.”
He’s barely pressed the wand between Iida’s legs before he starts bucking on the bed, the keening barely restrained by the gag. Iida is already so wet to this point that Sero can feel droplets of him hit his hand. He moves the vibrator up and down his folds, nudging under his hard little cock, and the bed shakes with the force of Iida’s thrashing.
“Pretty powerful stuff, huh?”
Iida’s too incoherent with how much the sensations are fucking him up to respond with even a nod. The head of the wand goes just into his hole and upward, and his eyes roll up.
“See? This is fun when you can’t get away. I mean, fun for me, but also judging by all the wiggling you’re doing, I think you’re feeling good too, right?”
Sero scoots a bit closer, rubbing his cock with a hand.
“Watch, Tenya. This is where it gets really fun.”
When Sero puts his cock in, there’s no friction, really. Everything is warm and wet, a tight perfect hole for him to thrust in and out of shallowly. “Mmm...mm…” Iida raises his hips in response, clearly enjoying the break from the too-powerful vibe.
Sero almost - almost - feels guilty for bringing it back down against his cock again. He moans loudly as Iida’s cunt pulls in around him, close, getting closer...and then Iida starts coming. It’s gushing, a mess of fluids that soak Sero’s dick and get him moving fast, slamming deep inside of Iida and holding his hips with his fingertips.
Part of him expects Iida to tap out, but he doesn’t. Even though he’s practically howling on the other side of the tape over his mouth, so loudly that at one point Sero leans over and presses a hand there just to reinforce it, then pinches his nose. “Jesus, do you want the whole dorm to know how thirsty you are?!”
That doesn’t do any good. If anything, the addition of a breathplay element just makes Iida come again the moment Sero takes his hand away.
The thing about the vibrator is it’s not just good for Iida, either. The sensation of what can only be described as full-body quaking goes right to the core of Sero’s cock, and he makes the mistake of just brushing it against the ridge of his head mid-thrust, howling as he comes without warning or time to prepare. Everything is soaked— with him and Iida both.
And there’s really no way of telling how many times Iida has come, that’s for fucking sure.
Speaking of which…
Sero settles back on his heels, picking the wand up and gesturing with it as he tries to catch his breath. “You know, Tenya…” Yes, they’re now on a first-name basis. “It’s a faux pas for a sub to just come without permission. Like you didn’t even try to ask me, you know.”
Iida’s expression is...incredulous. The orgasms have clearly knocked him a little silly and out of subspace, because already he’s trying to argue through the gag, and Sero tuts.
“No, no, no. I don’t want to hear it. Now, you have to be punished. That’s just how it is.”
Iida’s eyes are focused in on him as he picks up the wand, still powered off, and turns it so it’s lying on Iida’s belly. He tapes it down right where the head of it will sit on Iida’s cock, and watching his face, Sero turns it back on.
This time they are barely a minute in when there’s a knock on the door. Sero casually pulls his pants up and wanders over to open the door. Bakugou and Kirishima are standing there, and clearly they were not expect Sero to be the one to answer. “What the fuck is with all the noise, duct tape face?!” Bakugou demands, recovering quickly.
“Tenya and I are having some fun.”
Kirishima glances over Sero’s shoulder before turning bright red. “Holy fuck,” he whispers.
“Told you.” Then, he has a thought, and a huge smile spreads across his face. He opens the door a little wider. “You guys got any plans tonight?”
After all, getting Iida to chill out a bit is a goal everyone in 1-A has...right?
