Chapter Text
Izuku is miserable.
Well, no, actually he’s really happy. He’s Kacchan’s boyfriend!
Boyfriend!
He still can’t believe it half the time. It’s like something out of a dream! He gets to reach out and hold his hand whenever he wants, kiss him wherever he wants, and be with him whenever he wants. It somehow feels like they were always meant to be this way—sticky and glued to each other’s side more often than not. Kacchan loves him, and Izuku loves him, too. It makes Izuku’s heart sing.
But… ever since getting with Kacchan, he’s had one very irritating issue.
Izuku is horny.
Like, all the time.
Sure, Izuku would feel the urge before they were together, and he’d give himself attention when he needed to, but now there’s a constant zip of arousal every time he even so much as thinks of his boyfriend.
Which happens a lot. Can you blame him? It’s Kacchan!
But they’re still new to this relationship, and Izuku doesn’t want to rush things. Kacchan hasn’t brought it up, and Izuku’s taken glances at his lap during movie nights, and knows he doesn’t have the same issue. He doesn’t want to push something the other isn’t ready for.
So Izuku came up with a strategy. It used to be that after classes, he’d head out to do some hero work, and then usually end up in Kacchan’s room to hang out after getting back. Then, when he’d be alone in the dark, he’d always find his hand on his dick within minutes. But then came the problem of sporting a half chub the whole time he hung out with his boyfriend, and lately, with them getting more and more confident kissing and touching, sometimes he has to hide his discomfort as he shuffles out hard.
Now, he goes back to his room, rubs one out as quick as he can, and then showers before meeting up with Kacchan.
It works fairly well. Sometimes his dick will still twitch pathetically, inappropriately, just because Kacchan curls into Izuku’s side, but he manages to keep it from getting obvious. He’s pretty sure Kacchan doesn’t notice.
Until one night, when his shift went slightly overtime, and he had to skip the jerking off part.
Izuku’s still buzzed with adrenaline from work that hasn’t quite settled down yet. He knows he’s tired, but he’s also a little bit shaky.
Kacchan catches on immediately.
They settle against the comforter and pillows on Kacchan’s bed, and he props his laptop in between their legs before starting a movie.
As soon as he hits play, Kacchan demands, “Give me your hand.”
Izuku instinctively hands his right hand over. Kacchan grabs it, appearing harsh, but his touch is gentle even as Izuku’s fingers twitch and shake.
Then there’s a little bit of pressure as Kacchan’s thumb starts moving, massaging the scarred tissue.
It feels heavenly.
Izuku lets himself get lost in the soothing ministrations, humming whenever something feels particularly nice. The touch leaves a nice little buzz fizzing under his skin.
It’s all fine until Kacchan brings up that hand and kisses it.
Because oh no, now all Izuku can think about is Kacchan’s mouth. He sees those lips touch the scars on his skin, and suddenly he’s on fire, thinking about other places those lips could be, or pushing his fingers further into that pretty mouth. He knows blood is already flowing in the absolute wrong direction just from that one thought.
He screams at himself to stop it, think about something else, do not get hard do not get hard do NOT. It’s so inappropriate to be fantasizing about anything like that!! Kacchan’s just innocently trying to make him feel better and Izuku’s turning it into something lewd!
Voice just a little higher pitched than normal, Izuku says, “Thanks, Kacchan! I feel much better now.”
Kacchan pulls back and squints at Izuku. He might very well know Izuku’s lying, but he eventually lets it go with a nod.
Then Kacchan slides down lower on the pillows, and leans his head into Izuku’s side, throwing an arm around his waist. Izuku nearly jumps.
“Oi, what’s wrong?”
“Nothing, nothing!”
A brief pause. He’s clearly not believing that at all.
“Did something happen at work? Fuck-- are you hurt?”
Izuku is quick to reassure. “No! I would’ve told you, I promise. I’m fine!”
But Izuku knows Kacchan can still feel how tense he is. It doesn’t take long for him to speak up again.
“Should I change the movie?”
“No! Kacchan, the movie is good!”
Now Kacchan pulls completely away. “Are you mad at me or something ?”
“No!” Izuku quickly snatches up his hand again, to prove it. “Kacchan, no I’m not mad at you, I swear.”
Kacchan still looks a little wary, definitely confused, but doesn’t pull back anymore. “Then why are you being so… weird? Like you hate when I touch you.”
And oh man, he clearly tries to sound annoyed, but it’s more like a pout. Izuku’s heart squeezes. Although a slightly perturbed Kacchan is adorable, he does not want him thinking that way at all.
“God, this is so embarrassing,” Izuku mumbles after deciding to come clean. “It’s not that I hate when you touch me. In fact, it’s the opposite.” He grimaces. “I like it too much.”
Izuku watches Kacchan’s face as he processes that. It doesn’t click right away. His eyebrow raises, as if to ask why the hell would that be a problem, and then he looks Izuku up and down like that might give him a more clear answer.
And when his eyes land on the not-so-subtle tent in his lap, it does. His jaw falls upon the realization.
“You’re hard.” He says. There’s no emotion in it, so Izuku can’t discern what he’s feeling.
Izuku gulps and nods.
It goes quiet again. Kacchan looks away, staring at something or nothing at the front of the room.
When he does speak again, it’s in a strange whisper, “Why didn’t you just say something?”
“It, um. Happens a lot, when I'm around you. Or thinking of you. Or just—Ah!" He cuts himself off before he says something more embarrassing. "But I don’t want to rush things, Kacchan. And I don’t want to pressure you if you’re not ready for…”
Kacchan grumbles at him. “Who said I’m not ready? Fucking making assumptions.”
Well. Okay. Guess they’re talking about this now.
“Are you, um… ready?”
That gets Kacchan to pause, now that he’s not indignant about Izuku making assumptions. Eventually, he shrugs.
“Dunno… maybe start with small stuff.” He looks down at Izuku’s crotch for a split second, and then his eyes drift to the side and a light blush starts filling his cheeks. “I can… help you with that?”
He says it like a question, and Izuku is not about to let uncertainty lead their next decisions. So he takes a breath, and takes hold of Kacchan’s hand.
“Maybe next time,” he acquiesces. And then bites his lip to prod further into this new territory. “Kacchan, I know this stuff is awkward to talk about, but I think I want to have a conversation about, uhh, y’know, these things, before we do anything.”
Kacchan stares at the movie, lets it keep playing, but doesn’t say anything in response at first. Izuku keeps fiddling with his boyfriend’s fingers. Eventually, they twitch in the slightest clench, and Izuku takes that as permission to start talking.
“So… how often do you, um, get off?”
Kacchan immediately pulls his hand away and covers his face in his palm.
“Just kill me now,” he groans.
Izuku cringes. Maybe that wasn’t the right way to start.
“Sorry.”
“No, I just… ‘s embarrassing.” Kacchan huffs, and stops hiding his expression, though he still refuses to look Izuku in the eye. “The meds I’m on make it a little… difficult, now. One of the side effects is… I can’t…” He makes somewhat of an aborted growl, and raises his hand in a “get up” motion. Izuku immediately sits up straight at the information, eyes wide. Kacchan clicks his tongue, “You get it. But before everything went to shit… maybe once a week?”
“Oh okay.” Izuku nods, looking down at his own lap, where his friend remains stubbornly tenting in his shorts. “Uh, I think I’m more like, at least once a day.”
Kacchan chokes on a laugh, or a wheeze. “Jesus. Okay.”
“But that doesn’t mean we have to do anything, I swear!” Izuku promises, now turning to face Kacchan completely. He cups one side of his face, trying to gauge Kacchan’s reactions in this difficult talk. “I—I don’t really know anything about this side of you, Kacchan. Ever since elementary school, you’ve never shown an interest in anyone. I thought you detested even the idea of a relationship.”
His boyfriend scoffs immediately. “Yeah. ‘cause it’s gross. I hate all that sappy romance shit.”
Oh.
Izuku starts to pull his hand off Kacchan’s cheek, but it’s grabbed a second later and put back.
Now, Kacchan looks right at him to yell, “It’s not gross with you, you idiot!”
Izuku blinks. Kacchan sighs, and rubs at his busted arm (a nervous habit Izuku’s noticed since the bandages were removed), while Izuku gently thumbs at his cheek.
“The thought of relationship things—sex, kissing, fuck, even holding hands—it makes me want to hurl, usually. Has since, forever, I guess. But not with you. I feel like…”
He trails off, eyebrows creased and teeth clenched.
Izuku can’t help it. He has to kiss him. So he does, one quick peck on the lips in a hope that it will loosen them.
“Please tell me, Kacchan.” Izuku begs, and he’s not ashamed about it. He needs to hear what Kacchan’s about to say next, needs it like he needs air, and he desperately hangs on the edge of each word escaping from those pretty, pretty lips.
“Fuck. Fuck you. Shit. Because I trust you, okay? Fuck you!”
He finalizes the statement with a weak punch to Izuku’s shoulder. It’s so endearing the Izuku wants to squeal. (He doesn’t out loud, but internally? Choirs are singing in Izuku’s soul).
Instead, he leans down slowly. Enough time to give Kacchan a chance to pull away if he so chooses. But when his lips are close, Kacchan tilts his chin up just a bit to close the gap, letting Izuku kiss him without any resistance.
It’s a gentle, brief thing. With such a vulnerable conversation, Izuku wouldn’t want to overwhelm Kacchan with anything more.
After the kiss, Izuku presses their forwards together to whisper his response.
“I trust you, too, Kacchan. You’re the only one I want to do those things with.” Another quick peck, this time to his cheek. “And for the record, if you never wanted to hold hands, or have sex, I’d love you just the same.”
It takes a moment, but Izuku feels Kacchan’s next exhale on his face. His body slumps with relief, falling into Izuku even more as the tension bleeds out of him. He ends up hugging Izuku around the waist with his head on Izuku’s shoulder.
“Yeah. Well. Same to you. Though it seems that’s not gonna be the case, horndog.” He rubs a hand on Izuku’s thigh, making him jump in his seat. “So. We talked. Now can I help you?”
“W-What would you even want to do?”
“Here,” he sticks out one leg, putting it in the middle of Izuku’s lap. “Grind against me or whatever.”
Izuku chokes. “Like a dog?”
“Yeah. Congrats on figuring out the origins of the term ‘horndog’—bark bark, motherfucker.”
Izuku rolls his eyes, chuckling just a bit before pushing Kacchan’s leg away.
“No thank you, Kacchan. Listen… I want our first time to be both of us, together. I don’t mind waiting, I promise.” Maybe that makes him a hopeless romantic, but it’s true. He wants it to be an experience they can share. Even if it takes months or years, he wants to wait for Kacchan to be able to have the pleasure, too.
Kacchan searches his eyes just for a moment, as if analyzing his promise. He must find what he wants, because his smile turns soft, maybe a little shy.
“You horny sap.”
Izuku agrees. “Your horny sap.”
Kacchan takes that moment to kiss him. It feels really, really nice. Izuku hums into it. Kacchan’s a really good kisser. He cradles Izuku’s jaw for a tender, beautiful second before pinching his cheek and pulling away.
“Can we actually watch this fucking movie, then?”
Izuku tries. Really, he does. Eventually, his boner fades, but not because Izuku is focused on the movie. Instead, he’s reevaluating everything he knows about Kacchan.
Kacchan doesn’t get aroused as often as Izuku. And right now he can’t. But he trusts Izuku. He wants to have sex with him, one day. Wow. Wow wow wow. How exciting! He likes “sappy shit” when Izuku does it. He smiled so sweetly when Izuku said they’ll save their first time until they both can have it.
Until then, Izuku will just have to keep jerking off in the shower to thoughts of Kacchan. That’s fine. But what about Kacchan? He won’t get much relief until the medication or something else changes. That’s not fair.
“What is something intimate for you?” He blurts, before he can stop himself.
Kacchan twists to look at him like he’s crazy. “Hah?”
Izuku starts rambling, “I know getting off isn’t on the table right now, but I’d like to do something that resonates with your idea of intimacy. Like the next steps for you? Without needing… you know.” He grimaces as he realizes he’s been gesturing at their crotches. As if Kacchan wouldn’t already know what he was talking about.
Luckily, Kacchan doesn’t seem to take offense to that. Instead, he seems to be earnestly thinking about a response.
… Or he’s just ignoring Izuku. That’s definitely a possibility. Ugh, why does he have to be so awkward—
“I fucking hate it when people touch me anywhere, but especially places I can’t see.” Kacchan says, interrupting Izuku’s spiral. “Like between the shoulder blades, or whatever. But… I might not mind it if it’s you.” The tips of his ears are pink with blush.
Ahhh. How sweet. Izuku likes this as a compromise. One day soon, he can give Kacchan a massage, touch him and bring him pleasure. It sounds really nice.
“Noted. Thank you, Kacchan.”
And he stares at his pretty face. Because it is pretty. Kacchan has such beautiful eyes and lips. He wonders what they’ll look like when he’s moaning from Izuku’s touch. His nose is cute too, the way it scrunches at any minor inconvenience, and that downward angle of his eyebrows is adorable in the way they twitch when Kacchan’s is annoyed the same way they’re doing now—
“Izuku.” It’s a growl. “Watch the damn movie before you pop another boner.”
“Ah, yes Kacchan!”
