“Look at you scrawny little shit!” Kacchan barks, throwing away his shirt. Kacchan’s piercing red gaze is pointed at Izuku and that look alone has his knees weak.
Izuku stumbles with his things, dropping his socks to the ground. Embarrassed, he kneels down to pick them up, but keeps dropping his shirt, then the socks again. His ears burn hot from all the snickering from Kacchan’s friends.
Once he successfully gathers everything he gets up, only to be met with Kacchan looming over him. One arm propped confidently against the lockers, a wicked smirk dancing on his lips. Izuku tries his best not to look at Kacchan's very naked body.
“You’re so pathetic, ya know?” Kacchan muses, looking at him like he’s weighing his options. “I almost want to burn your ugly shit, but,” Kacchan fakes a gag, “I wouldn’t wish the sight of your shitty body on anyone.”
Izuku’s shoulders slump. Sure he’s skinny, doesn’t have that much meat on his bones compared to most of the kids in their class. But he isn’t that ugly.
Am I even sure about that? The only ones that call me handsome are my mom and…
Izuku swallows thickly as he dares to look at Kacchan. Auntie Mitsuki.
Kacchan scoffs. “Too scared to talk, you little shi—”
“Boys! Showers and out in fifteen!” Their teacher peeks through the door.
Kacchan grits his teeth and lucky for Izuku, he only slams his fist against the locker. “You better be out of here once we’re done with the shower or your clothes might not actually make it out.”
To reinforce his words, Kacchan pops a few explosions in his palm, making Izuku yelp and drop everything from his hands. Kacchan barks a laugh and turns back to his cackling friends.
Izuku watches them leave for the showers.
It only takes him a minute to gather himself, a shiver running down his whole body. Kacchan was naked and so close to me.
Quickly he picks his things up, dresses himself, and shuts the locker.
He picks his backpack from the bench and eyes the other lockers. His fingers stretch and then grip the backpack harshly. This is his chance. Like every week.
Izuku listens and makes sure the water is still running before he stalks forward. He stops at Kacchan’s locker, fingers itching as he reaches to open it. The familiar, low creak always makes his heart jump involuntarily.
He drops his backpack to the ground, leaning into the locker. The heavy scent of sweat gets him salivating almost instantly. Oh, how he wishes he could grab everything with him. But he knows better. Kacchan will be so angry if his gym clothes go missing.
So Izuku settles for what he always does. He leans in, pushing his face into Kacchan’s shirt, the one he just wore on the field. A moan escapes his lips as he takes a deep inhale.
He’s almost drunk. But this isn’t the best thing in there, not even close. Izuku frowns. Apparently Kacchan has hidden his shorts under something. But luckily, the underwear are where they always are — on top.
Izuku crouches down to his backpack and rummages for a while before he finds what he’s looking for.
Kacchan’s underwear.
Izuku sighs, thumbs running over the fabric longingly until sounds from the shower kick him back into gear.
Heart beating rapidly, he picks up the pair from the locker and replaces it with the one he took from his backpack.
He hides the underwear and shuts the locker with haste.
The sounds of running water end and Izuku’s eyes widen. He bolts out of the changing room, fingers burning, mouth watering just from the thought of having a new, fresh, sweaty pair of Kacchan’s underwear in his possession.
Once he’s out and far enough, he leans on the wall to take a breath.
Yet again, he was successful. This has been going on for months. He takes Kacchan’s underwear with him, and replaces the old ones with new ones.
He’s been interrupted a total of two times, so he currently has three pairs with him.
Oh, how he wants to slip somewhere private to get a sniff, maybe a quick taste before class…
He sighs, fingernails digging into his palms. No, he shouldn’t do this at school. Especially not this week. He has to focus. Kacchan’s birthday is coming up. And he needs to listen to all the conversations about it people might have.
Izuku knows what he wants to give, but Kacchan hasn’t accepted his gifts in years. This year he’s determined to succeed.
So if it isn't rare All Might stuff that Kacchan wants anymore, he must investigate.
As soon as Izuku gets home, he slips past the kitchen, barely greeting his mother on the way. Luckily, it’s not unusual behavior. He always holes himself up into his room after school before dinner is ready.
Izuku sets down his backpack, his fingers itching to grab the new pair of underwear he got.
He knows he should wait till evening, but considering there was no scent hanging out downstairs, his mom is a long way from starting dinner. He has time.
Without more delay he opens up the backpack and hastily pulls out all the underwear pairs he has. Three. Izuku shivers in excitement.
He’s still a little giggly about the All Might pair he has. Something he never thought Kacchan would wear to school willingly. Yet here they are — in Izuku’s hands from a few weeks back. The scent in them is almost gone, so he’ll give them back next week for sure. Right now, he’ll focus purely on the very basic black pair he snatched today.
He sets the other two pairs to the side before crawling into his bed. He sits against the headrest, wiggles down his pants slightly, just enough so his boxers are visible. Like this, he can pull out his cock whenever he needs to.
Izuku sighs, feeling comfortable as his mouth already waters. His free hand goes down, fingers between the pubes of his happy trail. At the same time he slowly lifts Kacchan's underwear towards his face, closer and closer, until they’re merely a few inches away from his face.
Izuku moans.
Fuck.
This pair is really musky. There’s a reason he loves to steal them after gym class. He doesn’t know why the scent is this potent today, but it doesn’t matter. He might be able to save these for longer, which is exciting on its own.
Izuku palms his already hardening cock through his boxers and whines. He imagines Kacchan face-first against the lockers, blushing, ass out and letting Izuku smell the sweaty bits between his legs before he showers.
Currently, that’s his second greatest desire—right after becoming a hero.
“Nn, Kacchan,” Izuku huffs, pushing the underwear right into his face. His whole body shivers and he has to pull down his boxers to grip at his cock.
He holds on tight, brushing the head to get a little lubrication in. At this point, Izuku usually grabs lube to make the glide better, but right now he’s just too horny to think. Kacchan’s sweat smells divine. Izuku groans as he swallows and opens up his mouth. His tongue comes out, licking the fabric eagerly. Even the taste is amazing—salty, with a hint of something sweet, something new. He has to write it down into his notebook after he's done.
Izuku speeds up his movement on his cock, gripping so tightly it almost hurts, but this is how he likes it. If there’s no pain, it just won’t work. He imagines this is how Kacchan would do it to him. Hold on so tight, maybe burn him a little…
Izuku almost comes from the pure thought of it and sucks on the underwear to muffle his loud moans.
Kacchan’s ass on his face. Kacchan’s hands on his skin. Burning. Pleasuring him with way too much force.
Oh.
Izuku whines as he comes, brain hazy, nose full of the heady scent of Kacchan’s sweat and mouth tasting it all. His hand is messy, his breath heavy and ragged.
Right after the endorphins settle even a little bit, Izuku hastily gets up. He’s made the mistake of messing up Kacchan’s underwear with his come a few times before and he’s smart enough not to taint them anymore.
He settles the underwear with the others, then cleans up his hand and cock sloppily. He’ll do better once he gets to the bathroom. But this is enough for now. Izuku sighs as he lays back down, letting his breathing fully settle.
Mm Kacchan…
Oh right, Kacchan’s birthday gift.
Izuku lazily looks at the side for his phone and groans when it’s too far away. It’s fine. He’ll get to it soon. He still has a few more days to actually figure out what to give Kacchan this year.
—
Izuku did his research. Stalked Kacchan a little more than he usually would, getting himself burned a few extra times. But it’s all good. All fine. Especially when Kacchan’s underwear feel so good against the burned brands on his skin.
Izuku sighs, mind getting lost in Kacchan. Kacchan’s scent. Kacchan’s piercing gaze. Kacchan’s hot palms on his throat. Kacchan’s foot digging painfully into his chest…
“Out of the way, nerd!”
Izuku yelps as his shoulder gets pushed and he loses his balance. Luckily, Kacchan only laughs and continues on his way.
Izuku humbly stays on the ground, eyes following Kacchan’s back until it disappears behind a corner.
Right. Kacchan’s gift.
During his research, he heard all kinds of things that Kacchan claimed to want. New phone, some new music player, expensive belt, some video game Izuku had never heard about before…
Izuku couldn’t believe it. None of the gifts sounded like the Kacchan he knew.
Kacchan hardly used his phone. Kacchan did like music, but he preferred very old fashioned ways. Like CD players. Things that their parents barely used. Kacchan was never one for clothes, either. Sure, he liked softer fabric over rough, but a belt?
Izuku frowned. Even the video game sounded nothing like what Kacchan liked. Kacchan wanted to compete. And a game with not a lot of online speedrunners wasn’t for him. So what gives?
Izuku really didn’t know. So he had looked at his shelf and picked his old, vintage Bronze Age All Might figurine. It hurt him to let it go, but if it was for Kacchan…
The figurine is currently burning a hole into his backpack. He needs to get it to Kacchan today. He can't be late. He hasn't even wished Kacchan a happy birthday yet.
With a new found resolution Izuku gets up, cleans dirt off of his clothes and hurries to the next class. He’ll follow Kacchan out after it and give the gift — a solid, easy plan.
—
Izuku follows Kacchan and his friends outside. He hovers, waiting till Kacchan is alone. Kacchan always ditches his friends for breaks, not fully, but for a while. So Izuku is patient and waits for his opportunity.
Once Kacchan separates from his band of meanies, Izuku stalks closer. He needs to stop Kacchan at an optimal time. Preferably somewhere there’s no one around. And where they are unlikely to be interrupted.
He follows Kacchan outside. His palms are sweating and he’s sure people are looking at him funny as he walks behind Kacchan. Izuku is a safe distance away, no way they know he’s following, but it feels like they do. Izuku swallows, hoping that Kacchan goes to somewhere where there’s less people soon.
But it seems like everyone is outside on their break. The sun is up and the weather is nice. Izuku hates it. It all prevents him from catching up to Kacchan and stopping him for a talk. If he does it out here where people can see, Kacchan will hate him. And going to Kacchan’s house after school isn’t ideal, but if he has to, he will.
Heat rises into his face as he imagines such a thing. He hasn’t been to Kacchan’s house since last summer. So nearly a year ago.
He always comes up with excuses whenever his mother wants to go have dinner at the Bakugous. He probably can’t avoid it too long now.
Last time was just so awkward. Sure, Kacchan seemed to have fun when they silently played video games upstairs to pass the time, but the boy had been so mad at him at school after that. He likes Kacchan’s attention, any kind, but that? It wasn’t fun. Kacchan had leered at him and then ignored him for weeks. There’s no way Izuku wants a repeat of that. Ever again.
Before Izuku realizes it, they’re back inside and Kacchan is heading towards the toilets.
Perfect. Maybe there’s not that many people in there or he can at least make Kacchan wait till possible loiterers leave.
Izuku straightens his posture a bit when Kacchan disappears from the door.
Okay Izuku. You got this. Just say happy birthday to him and give the gift. Simple. Two minutes tops and you’re done.
He takes a deep, shaky breath and opens the bathroom door. Instantly he’s yanked in, the door is pushed shut and Izuku’s back hits it with a force. All air punches out of his lungs and he has to cough violently a few times.
“You fucking stalker,” Kacchan snarls, his hand hitting the door hard beside Izuku’s head.
“It’s enough that you keep watching me all the fucking time, but this? Going around campus like I have some stupid dog on a leash behind me,” Kacchan scoffs, “disgusting.”
Izuku’s face heats up from the thought. If Kacchan would ever leash him, he’d take it. There’s no way he wouldn’t.
“Oh my god, don’t tell me you fucking liked that? Perv,” Kacchan sneers and grabs Izuku’s collar into his free hand. “Spill it. Why do you keep following me?”
“Um.” Izuku doesn’t dare to look Kacchan in the eyes. The piercing, hot, red gaze makes him squirm. “It’s Kacchan’s birthday so I just wanted to… Congratulate you and give you something.”
Kacchan’s eyebrow rises as his face moves impossibly closer. “I don’t need your shitty gifts.”
“Please, Kacchan.” Izuku squirms, trying to wiggle his backpack off while avoiding moving too much. If he touches Kacchan… Izuku gulps as the backpack falls into the ground and he hurriedly squats down to pick it up. Only problem is that lifting his gaze makes him meet Kacchans crotch.
Oh God.
Izuku looks down into his bag, opens it swiftly and rummages around for the gift. It’s easy to grab luckily since it’s big, barely fitting in with all his other things. He pulls it out, standing up at the same time.
Which was clearly a mistake as at the same time, other things fall out of his backpack. Books, notes, pencilcase and… Oh no. Three pairs of Kacchan’s underwear scatter onto the floor along with everything else.
And Izuku does try to go back down but unfortunately Kacchan is way faster. He’s already kneeling down, sneering at Izuku’s things.
It looks like he wants to grab a notebook first, but his hand changes course.
“What is this nerd? You carry around extra pairs of underwear? You jerkin’ off middle of the day or what?” Kacchan taunts, merely glancing up at Izuku.
Okay, that could work. They could technically be Izuku’s underwear too. At least the All Might pair. If Kacchan just won’t look at them any closer… Of course he does. Kacchan even picks one of them up and barks a laugh before finally looking up at Izuku.
“You’re even sicker than I thought. These from someone on our class? Ya fantasizing about stickin’ it into some girl, huh?” Kacchan’s smile is mean and Izuku doesn’t like it. He swallows thickly, trying his best to come up with any kind of explanation.
“N-not really… Those are actually mi—”
Kacchan gets up and pushes the underwear straight into Izuku’s face. It’s hard to not moan at the scent. This is the pair he got just last week. They still have that sweet, sweaty goodness etched in them and yes, with a single whiff, Izuku is hard in his pants, painfully so.
“Yours? I don’t think I’ve ever seen your nerdy ass use these kinds of underwear. Plain colors, really?” Kacchan scoffs. He moves the underwear a little, looking at them a little more closely. His eyes widen slightly and Izuku’s face contorts in horror.
“The fuck?” Kacchan moves back a few steps. He checks the underwear, kneels down and checks the other two.
All the while, Izuku is frozen in place. This is a nightmare. He’ll never live this down. Kacchan will surely murder him. Goodbye sweet life, welcome de—
“No fucking way,” Kacchan laughs, but it’s constricted. Izuku stays silent, his palms are sweating profusely around the wrapped gift box in his hands. He's waiting for the sparks to come to his face any moment now.
“You think your puny little dick would ever satisfy me?” Kacchan finally says and Izuku’s mouth opens up in disbelief. What. He didn’t just hear Kacchan say—
“There’s no fucking way,” Kacchan sneers and his hands are already on Izuku’s belt. Izuku is even more confused by the second as Kacchan’s fingers work on his belt and start pulling down his pants. What the hell is happening?
“Of fucking course you’re already hard. Perv,” Kacchan muses, but his eyes are locked on Izuku’s cock. Izuku’s face is so hot it feels like he’s been set ablaze. He clutches the box in his hands against his chest, hugging it tight.
Kacchan licks his lips and Izuku thinks he’s already dead. He must be. Why is this happening? Why is Kacchan looking at his bulge, licking his lips, touching him— wait, touching?
Izuku shivers as Kacchan’s hot palm runs along his hard shaft over the underwear. It’s hard to keep his voice down when he wants to moan just from this.
“Fuck. You’re actually—” Kacchan cuts his words in the middle and scoffs. Izuku would love to hear everything Kacchan wants to say, but he’s not going to push it. Not now. He doesn’t want this moment to end with any of his stupid ramblings.
Next thing he realizes is Kacchan pulling down Izuku’s boxers, then getting up and taking off his own pants too.
Izuku gawks. He’s seen Kacchan naked before. He’s looked, he’s always been curious like that. But he’s been hiding his own body as much as he can. So he’s not shocked, but he’s salivating from the sight. It’s Kacchan, getting naked in front of him voluntarily. Not for a class or anything, but for Izuku.
Kacchan huffs, grabs the box in Izuku’s hands and throws it to the side. Izuku winces since the All Might inside is expensive, one of only five hundred printed, but he lets it go. How can he even think about All Might when Kacchan is grabbing his cock? Not even just that, but they’re now so close, dicks pressed together and Kacchan is peering down at them.
The blush on Kacchan’s face is so precious. Darker than Izuku has ever seen before. He wants to touch…
“How in the hell,” Kacchan mutters, his hand moving up and down their dicks. The simple touch at the tip has Izuku gasping. “You’ve been hiding a monster. Fucking hell, Deku. You’re going to break people with this.”
Izuku holds his breath.
“Scratch what I fucking said earlier. In fact, I’m the only fucking one who can take this thing.”
Now Izuku is certain that he already died. It doesn’t matter though, this is way too good and a dream come true. If this is the last thing that’ll ever happen to him, he’s happy.
Kacchan hasn’t looked Izuku in the eyes for a while, but finally those eyes look up. They’re burning through Izuku and he can’t look away. Kacchan is so beautiful like this. It’s a totally new look on Kacchan and Izuku loves it, wants to memorize it and never forget it.
Kacchan is hard against him. So this must be how he is when he’s horny. Izuku has seen Kacchan mad, frustrated, happy and even crying. There’s nothing else this can be.
“You’ve been awfully quiet huh, nerd?” Kacchan smirks. It’s so sexy Izuku thinks his legs might give out. Kacchan squeezes their cocks in his palm and Izuku can’t keep the moan in his throat any longer.
“Yea? You really thought you’d be sticking this into some girl? Or you’ve been thinking about me after all? I fucking mark my underwear idiot. I know those are mine.” Kacchan’s toothy smile is so beautiful, Izuku can’t even deny it.
“Didn’t want any girl,” Izuku manages to say. His throat is dry and he tries to swallow. “Wanted Kacchan’s… Smells good,” Izuku admits.
Kacchan’s pupils dilate for a second before he scoffs. “Perv.”
Izuku can see Kacchan is pleased. And doesn’t that alone make his cock jump in Kacchan’s firm hold.
“Why ya been hiding it? Think I can’t take it?”
“N-no, Kacchan! Of course Kacchan can take anything. Kacchan is amazing,” Izuku quickly says. He’s so afraid Kacchan will leave him all hard and wanting in the bathroom.
“Tch, damn right,” Kacchan boasts. “I ain’t skipping class for this though.” As he says it he kneels back down, both knees on the cold, hard tiles and he lets go of his hold. Izuku whines at the loss of contact on his leaking cock.
Kacchan's palms rise up to Izuku’s thighs and he startles a little bit, but no sparks burn his skin. Instead Kacchan leans closer with his face and Izuku’s eyes widen. Is Kacchan really going to—
Even the gentle breath in his cock is almost too much, so when Kacchan’s tongue comes out to lick at the tip, Izuku’s knees buckle. Luckily, Kacchan’s grip on his legs keeps him upright. The hold is bruising, but it’s welcome; it feels good, grounding. Izuku almost wishes Kacchan would also burn him a little.
“Keep yourself up, shit,” Kacchan grumbles, “the break is probably almost over.”
Izuku nods hastily and Kacchan goes back to work. His tongue comes out again, licking at the slit, then around the head. Kacchan’s lips hover around the angry red head, before landing what almost feels like a kiss on top.
Izuku can’t look away. His eyes are locked down into Kacchan. It’s everything he’s dreamed about. The brash blond on his knees, opening his mouth up and taking Izuku between his plush, pink lips.
Kacchan moans against his cock, clearly trying to take the whole thing in at once. The vibration sends shivers down Izuku’s spine and instinctively, he lowers his hands into Kacchan’s hair. He grips harshly, making the angry, red gaze look up at him.
“So good, Kacchan, perfect,” Izuku says, all breathy and desperate. Kacchan seems pleased, his jaw relaxing around Izuku as more and more of the hard cock disappears into his mouth.
It’s sloppy, the movement of Kacchan’s mouth uneven and he gags more than every other mouthful, but Izuku doesn’t care. To him, it’s perfect. Every desperate whine from Kacchan, every swipe of a tongue on the underside of his cock, every hit at the back of Kacchan’s throat.
“C-close, Kacchan.” Izuku’s voice wobbles. He’s been good with only keeping hold of Kacchan’s hair and not dictating the pace. It’s so hard not to take control, get a few harsh thrusts in so he can come.
Instead, Izuku lets go with one hand and pets Kacchan’s soft spikes. “You’re so perfect Kacchan. Such a good mouth,” Izuku pants, cock twitching when he realizes there are tears at the corners of Kacchan’s eyes. It looks like it’s unpleasant for him, yet Kacchan is doing this all, continuing and making Izuku unravel in record time.
“Amazing, Kacchan,” Izuku whispers, too mesmerized by the sight. Kacchan shudders and Izuku feels something spray into his ankles. It doesn’t take much to realize that Kacchan just came. Untouched and all over Izuku’s pants and legs.
The realization alone gets Izuku over the edge and he spills his load into Kacchan’s hot, eager mouth. The fact that Kacchan isn’t pulling away is even more incredible.
Izuku’s body almost folds in half from the pleasure. He’s shivering, barely realizing that the bells start ringing in the halls.
Kacchan pulls away from him, wiping the corners of his mouth and getting up. Izuku is too dazed to do anything while Kacchan gets the water running and cleans himself in silence. He should move too. Clean his pants from Kacchan’s cum, get dressed, pack his bag and get to class. But he’s too blissed out to do anything.
Izuku finally comes out of it when Kacchan pushes the gift harshly against his chest. “Put this into my locker. You’re such a freak you probably know the combination anyway. I’m going back to class.”
With that Kacchan is pushing him to the side from the door. He leaves Izuku there — pants down by his ankles, clutching the birthday gift in his hands and alone.
His legs want to give out, but he doesn’t let them. Instead he stays up, thinking about what just happened.
Kacchan sucked him off in the school bathroom in the middle of the day. Said he’d be the only one able to take Izuku. Somehow even after all that his cock twitches and Izuku scrambles to clean up.
He has time to find out what exactly Kacchan meant with all his words. Now he needs to clean up, take the gift to Kacchan’s locker and find an excuse to why he’s late for class.
