Work Text:
It’s 4am in the dorms, and Izuku comes down to grab something to quench his sudden early morning thirst. He settles on a cold glass of milk, sitting on one of the stools there while he sips sleepily. Somehow, he falls asleep at the kitchen counter, and when he wakes up, it’s to the sight of Kacchan guzzling water from a bottle by the large fridge. The blond is wearing a tank top with grey sweatpants and HOLY FUCK is Kacchan half hard?!
From the side, it’s all Izuku’s eyes can focus on, ignoring the bulging arm muscles and the way his Adam’s apple bobs up and down.
Kacchan’s Dick.
He’s never thought about it before, but suddenly, it’s all he can think about. Is the room suddenly hot? Maybe he should also have some water.
His eyes are glued to The Bulge. He wants to check how hard it is for himself because Kacchan might just be going without underwear for it to be so... visible. After all, it’s the early hours of the morning. Kacchan might have just woken up and pulled on the closest thing which means: Kacchan sleeps NAKED.
The thought sends him to his feet, movements jerky from sleep. Kacchan stops drinking his water and turns to face him, red eyes scrunched at him.
“Oh you’re up now. You shouldn’t fucking sleep here, you have a bed.”
Izuku is too tongue-tied for now he has a front view of the sizeable bulge, and he doesn’t know how to operate his limbs anymore, let alone his mouth.
He tries to walk out from around the counter, head for his room, take care of the maelstrom of unacceptable thoughts in him; but something goes wrong with his brain connection and he stumbles, nearly crashing to his knees in front of Kacchan.
The blond clicks his teeth, reaching out to grab Izuku before he can make a fool of himself.
Kacchan hands are warm, his dick is half hard, his body is so close... Izuku wants to melt from the heat that is searing his face and the unholy thoughts he has only ever had about girls.
Kacchan looks at him hard for a few seconds, taking in his red expression and following his gaze to where it keeps going like it’s magnetized.
“Oi Deku. Like what you see?” says Kacchan with a smirk that makes Izuku shiver.
Izuku has seen Kacchan smirk hundreds of times, but suddenly, new adjectives have been added to describe it: sexy, smoldering, HOT. He stumbles away, tripping over his own feet to get back to his room.
Once there, he locks the door and presses his blushing face against his pillows. Kacchan. Kacchan is hot.
This is how Izuku found the gay within.
∞∞∞
On the surface, nothing has changed. Izuku still goes to classes, does his insane One for All training and internships and hangs out with his friends. However, his mind still sends surprise images of Kacchan’s dick print at the most inopportune times.
While he’s sparring with his friends, just as he is about to perform a move that will surely lead to his win, the afterimage of the most seductive bulge he has ever had the blessing to see flashes by.
Every single time, it severs his brain connection. He’s ending up with a lot more bruises than he should be thanks to this.
He has been steadily trying to repress the image. If he doesn’t think about it, it doesn’t exist, and if it doesn’t exist, he won’t have any memories of it. Simple.
But like everything about Kacchan, even the memory of his dick print shines so brilliantly: Izuku has trouble looking away.
It is a frustrating time for Izuku as he struggles to contain this new outpouring of feelings, while surreptitiously combing the internet on why he feels this way about his friend’s dick.
It all comes to a head when he’s sparring with Kacchan. It’s hand to hand combat, and they’ve been at it for a while. Izuku’s hair is sticking to his forehead as he focuses on the person mere feet away. Kacchan’s tanned skin is glistening: he might as well have sprinkled gold dust on himself. It’s distracting, but it’s nothing Izuku can’t handle.
Then Kacchan swallows, lips spreading in a cocky grin as he attacks again.
Unfortunately, Izuku’s eyes follow the movement of that gleaming Adam’s apple. His quick brain starts making rapid associations. Kacchan swallowing... Kacchan drinking water at night without underwear... Kacchan’s Dick!!!
It is his kryptonite. By the time his body resumes its functions, he’s taking a hard blow to his unprotected guts. It reverberates through him, doubling him over and leaving him gasping for air. He falls to his knees, ashamed but in too much discomfort to stop.
“What the fuck?! Are you trying to get hurt?!”
Kacchan’s warm hand grips the scruff of his sweaty shirt, using it to tip his head back. Izuku closes his eyes. He doesn’t want to see the disappointment or whatever kind of look that Kacchan is giving him.
“Sorry.”
“Tch. You’ve been a total klutz the last few days. What’s going on?”
“Nothing. “
Kacchan’s grip tightens, pulling him from the near fetal position he’d assumed.
“Oi. Fucking look at me when you lie like a bitch.”
Izuku groans in a fit as Kacchan refuses to let him curl in peace. He opens his eyes to find the blond scrutinizing him. The red eyes impale him with their intensity. Why should Kacchan be able to look at him like this?! He feels his limbs loosen, and he obediently sits up. He has to look away though… those eyes.
He focuses instead on the pain radiating from his abdomen, lifting his sticky shirt to view the blooming bruises.
“Ah! Look what you did Kacchan! This is gonna suck,” Izuku pouts, pointing accusingly at the bruise.
Kacchan looks away quickly, rising from the near crouch he’d adopted. Izuku is too focused on examining his bruise to note the flush on Katsuki’s cheeks from his sudden exposure.
“You did that to your fucking self. Now get up. I’m going to pound you into the mats.”
Izuku’s eyes widen in shock. Does Kacchan understand the double meaning of what he just said?!
“P-pound me?”
Izuku’s traitorous mind is thinking about his dick again. Bad Izuku! Stop!
Kacchan grins, sharp and sexy. Oh boy. He has to know. He has to. “What, are you scared of getting your weak ass ruined?” Low voice, intense bedroom eyes.
Izuku squeaks as the newly discovered gay within him wreaks havoc on his mental scape. What in the world was Kacchan doing?! And why was he doing this now?!
He feels lightheaded as Kacchan pulls him to his feet. His limbs might as well be paper mâché for all the tension within them.
“Alright Deku. Let’s fight for real. No more of that distracted shit.”
Izuku nods, despite his immense distraction. Kacchan’s Dick!! Pounding him!! Ruining his ass!!
Kacchan... Kacchan is going to ruin him.
∞∞∞
Izuku takes a long hot shower to loosen his sore muscles. As the spray lands on his face, he finally permits himself to think about the elephant in his brain: Kacchan’s Dick.
His hand clamps over his mouth as he thinks of The Bulge. Wow. He feels like he must have imagined it. There’s no way Kacchan would sleep naked or let himself be seen like that. After all, it was literally obscene and a hazard to society.
Izuku is beginning to feel certain that he dreamt it up. It was late at night, and he wouldn’t put it past himself to imagine something so odd.
He refuses to acknowledge the part of him that insists that straight people don’t dream about other guys dicks or think they’re hot. In fact, he drowns that part out quite thoroughly with the water, happy to wallow in self deceit.
Since The Bulge was a dream, it doesn’t exist, and if it doesn’t exist, he doesn’t have to be so flustered about it! Problem solved!
He feels some relief at sorting his stupid brain out. Izuku leaves the actual showers with his towel wrapped firmly around his waist and a fluffy All Might bathrobe around him. His sopping hair is wrapped in a towel as he approaches the sinks to brush his teeth.
Sadly, his approach is waylaid by the owner of a certain Bulge exiting a stall with a towel hung low on his hips, revealing the lean V and tiny waist that Izuku wants to wrap his arms around and never let go of.
In fact, he stands there dumb struck as Kacchan puts a towel over his head to pat it down and stop the droplets of water from running down his body.
Kacchan is fucking gorgeous. It is a new fact of Izuku’s life. A part of him has been aware of it for a long time, but it is only now that his entire being accepts that this will be what the rest of his life consists of: ogling Kacchan.
He vaguely acknowledges that his face is on fire, and he should stop hoping the precarious knot of the towel gets loosened so he can finally see the goods for himself.
“Take a picture, nerd. It’ll last longer.”
Kacchan’s deep voice breaks through his bisexual panic induced haze.
“Uhhh can I?” Izuku’s mouth and vocal cords operate without his permission, and he wants to Detroit smash his throat to save himself from ever saying something so mortifying.
“Sure. But you can’t share.”
And Kacchan winks. It is devastating when combined with that sexy smile. Izuku feels like his feet left the planet, and he suddenly cannot understand words.
“H-huh?” He is 2 seconds from exploding into bisexual flag themed confetti.
Kacchan just hangs the towel around his neck, giving Izuku a look™.
“Come to my room, Deku. Now.”
Izuku’s rosy blush can be seen from space. Astronauts in the international space station are probably wondering what the hell is going on in Japan.
“Oh my god Kacchan, how could you say that? To your room? You want to study? I’m not dressed yet. We don’t study together though hahaha. But I don’t mind studying with Kacchan. Actually it would make sense to see how Kacchan studies since-“
“Why are you like this?” Kacchan says, voice almost fond as he ushers the literal tomato ahead of him.
Izuku doesn’t even notice he has left the bathroom, he’s so deep in his muttering at this point. It’s only when he’s in Kacchan’s room that he realizes he has been moved.
“What? Kacchan! I haven’t brushed my teeth yet!”
The blond gives him a bored look as he rummages through his closet for clothes.
“I don’t mind.”
Izuku blinks. Then blinks again as he tries to allow his mind to unravel and process that statement.
“I- wh- do-“
“Deku, I know you’re into me.”
Izuku breaks into a sweat despite the cool environment. He eyes the door longingly, wanting to be anywhere but here in his bathroom attire.
“I-I don’t know what you’re talking about.”
Kacchan rolls his eyes. Somehow, he is now fully dressed in a tank top and loose sweatpants. The sweatpants. Izuku forces himself to keep his gaze on Kacchan’s eyes and not hunting for the thing that kick started this whole dilemma.
“I’ve told you: you lie like a bitch.”
“Kacchan, I am very s-straight.”
His laugh is dark, and he steps closer to Izuku, invading his personal space with his scent and body.
Izuku’s knees go weak as Kacchan pushes him against his wall, effectively caging him in. He is hyperventilating in his head, heart galloping.
“You sure? Close your eyes Deku.”
Izuku doesn’t think he can ever disobey Kacchan if he looks at him like that and speaks so close to his ears. He can feel the blond’s breath glaze his skin, a delicious tingle running up his spine.
His eyes close, and he automatically tilts his face up, wanting the kiss that must surely follow. He has never truly thought about kissing Kacchan (except for dreams which he will not mention) but it feels like a dream come true.
He is almost vibrating with anticipation.
Then Kacchan smacks his head.
“Ow!” When Izuku’s eyes open, he finds Kacchan at the door, holding it open for him.
“Alright then, get out.”
Izuku doesn’t know what to say beyond the wave of disappointment that floods his throat.
“Come on, I haven’t got all day.” He adds, impatiently.
“But-“
“You aren’t interested, right?”
“N-no,” Izuku whispers.
“Hah? I couldn’t hear you over all the fucking lies.”
“I’m interested.”
“You’re gonna have to say it louder.” Kacchan has the mean sexy look in his red eyes now.
“I’m interested!”
“Jeez, I must be hard of-“
“I’M INTERESTED KACCHAN!”
Izuku is breathing heavily, embarrassment rushing through him. He can’t let Kacchan kick him out, not after he’s gotten so close to touching him. He doesn’t know if he will survive it.
The blond smirks, full of lascivious intent.
“Come here Deku.”
They meet in the middle. Kacchan tugs the towel off his head, letting his tangled locks breathe again. His warm hands cup Izuku’s jaw, tilting his chin enough that all Izuku can focus on is the boy in front of him.
Izuku’s eyelashes flutter closed as Kacchan places a firm kiss at the corner of his lips.
“F-fuck. Can I kiss you?”
The way Kacchan’s voice wobbles makes Izuku feel infinitely better. Despite his racing heart, he leans forward silently begging for Kacchan to stop teasing him.
It still comes as a shock to his senses. Never has he ever kissed a boy. It’s the same: lips on lips, a hand on his hip, sharing the same air.
Yet, there are these subtle differences that send him tumbling down the hill to gleeful bisexuality: Kacchan’s deep voice, the male scent of light cologne, the short soft hair his fingers are currently running through and the insistent hardness pressing into his lower belly.
Wait, WHAT?!
Fire shoots through his muscles as Kacchan slips his tongue into the mix, and holy fucking moly Izuku is both ecstatic and terrified.
Their kiss is gaining momentum, Kacchan is tugging at his bathrobe, the earth is spinning too fast for Izuku’s brain. His touch feels burning hot in Izuku’s overactive imagination. He stumbles while standing when Kacchan’s hand finds his butt, a squeak escaping his lips.
“God, Deku, you make the cutest sounds. Makes me want to eat you up.”
Kacchan is kissing him again before he can reply. He’s swept up by the whirlpool of emotions coming from the blond boy. He doesn’t even realize when his bathrobe is off and all that is keeping his decency is a towel that’s already being strained by his obvious excitement.
He feels like he is one of Kacchan’s sweat droplets, about to be ignited and explode into a million sparks. It’s too much, he isn’t ready to explode yet!
“Ka- wait!” He manages to pull away from the warm body, gasping for air.
“Shit, are you okay?” Kacchan asks, rising to his arms, hovering over Izuku who is splayed on the bed.
“I- please put your shirt on.” Izuku’s face is red as he takes in the blond’s ridiculously attractive body.
Kacchan moves away from him, looking worried for the first time he entered the room.
“Deku, what’s wrong?”
Izuku fiddles with his hair with one hand, wrapping himself with his discarded bathrobe. How can he explain how he feels to Kacchan? It feels impossible and incredibly embarrassing.
“I need to moisturize else my skin is going to get all flaky!”
“I thought we agreed on no lies.”
Izuku bites his slightly swollen lip, not capable of meeting Kacchan’s eyes.
“Uhhh, we’re minors?”
Kacchan rolls his eyes. “So you’re just gonna walk away without saying why?”
“Ah no!!”
“Do you think I’d do this with just fucking anyone?!”
“Good. I don’t like to share!”
“Well then, tell me what’s wrong. Please.”
Kacchan’s red irises reveal his insecurities. Izuku cannot let it be this way.
He sighs looking down at All Might’s colors. “It’s just... too fast for me. I don’t want to be a prude, but I also get so overwhelmed. I’m sorry...”
“Idiot,” Kacchan says softly. “You’re not a prude if you want to take things slow. We can go at your pace. That’s fine too.”
Izuku blushes, nibbling his lips a bit more before meeting Kacchan’s gaze.
“If so...”
He reaches out to grab Kacchan’s hand, going as far as interlacing their fingers. “How about we start from here?”
Kacchan nods, a shy sort of grin on his face. “You’re taking me on a date later,” he informs Izuku.
“W-What?! Wait, Kacchan likes ME?!”
“Fucking idiot.” He squeezes their linked fingers, and Izuku feels the warmth behind the gesture.
Izuku realizes that he is very bisexual as evidenced by the passive aggressive boyfriend he acquires instantly.
And thus, Izuku accepts the gay within.
