Work Text:
Katsuki’s beginning to believe he’s cursed somehow.
Or, just royally fucked–as he finds himself trudging through the crowded hallways of UA for the fourth time this week. And it’s only Wednesday! He came by twice on Monday… he just can’t help it.
Kids barely pay him any mind these days, since he’s here so frequently. Why, you may ask, is he hellbent on returning to his old stomping grounds multiple times a week?
Well, it’s because Izuku’s here.
Lately, he’s discovered a lot about himself. One of the things he’s recently unearthed about himself is that he’s unapologetically drawn to Izuku in a way that he’d honestly tried so hard to deny for many years. Izuku has him wrapped around his finger in a way that his younger self would’ve certainly offed himself over. Straight up execution style.
Now, though, he can’t get enough of him. He finds himself agreeing to every proposed hangout that Izuku offers. Finds himself demanding he and Izuku be scheduled together on patrols. Finds himself going out of his way to see the nerd as often as possible–finds himself trudging through the halls of UA, hero costume and all, with the excuse of needing to bring Izuku his lunch.
He knows Izuku’s an adult. He knows Izuku could probably handle the making and bringing of his own lunch to work. He also knows that Izuku’s brain moves a mile a minute and he almost never brings lunch to work. The guy has a track record, for god’s sake, of only eating a bag of chips and maybe drinking an apple juice from the cafeteria. If he ever makes it out of his classroom during lunchtime–or, if Aizawa Sensei brings it to him during his free period because he’s sensed that Izuku’s ass hasn’t left his chair since he clocked in at seven thirty.
Heavy boots stop in front of Izuku’s classroom for the millionth time, his hand resting on the sliding door’s handle as the soft lull of Izuku’s teachings begin to fill his ears. He’s dropping by on his own lunch break, so the bento in his hands is actually made for two. Katsuki makes double every morning lately so he can bring it to UA, and they can eat together. That way, the nerd doesn’t feel so bad that Katsuki’s “gone out of his way.”
And, of course, so Katsuki can spend as much time as possible with him.
It’s a win-win situation, in his opinion.
With a deep inhale, Katsuki gently slides open the door to Izuku’s classroom. He doesn’t bother knocking anymore; he waited out here for ten whole minutes one time before Izuku finished his rambling and came and opened the door for him.
The door slides open, revealing the inside of the classroom he’s seen so frequently over the last few months. Katsuki’s eyes instantly land on their target; an emerald, curly haired Sensei with the sleeves of his white buttoned shirt rolled up to his elbows, his muscles barely being contained beneath the fabric as he moves his arms as he speaks, his slacks hugging his ass just the perfect amount…
Katsuki’s entire body feels like it’s been lit ablaze as his greedy eyes roam along Izuku’s frame. He looks strong, confident, sexy. A shaky breath leaves Katsuki’s slightly parted lips as he fully drinks in the sight of Izuku. He stands confidently at the front of the room, passion radiating off of him as he explains a lesson that Katsuki’s far too distracted to fully decipher.
Another thing Katsuki’s learned about himself recently, is that he has a thing for dumb, nerdy teachers.
He’s not sure what exactly does it for him, but he definitely knows that the fact that Izuku’s a teacher makes him feel a type of way that has his cock chubbing up whenever he’s exposed to it. Now, that exposure could be as simple as a mental reminder that Izuku’s a teacher. Or it could be an in person exposure, like right now.
Remembering where he is in space, he clunks his boots as he stomps through the threshold of Izuku’s classroom. He shuts the door behind him, and that catches Izuku’s attention. He turns his head to face Katsuki, his lips quirking up into a cheeky grin as he registers who’s just entered his classroom.
“Hi, Kacchan!” He greets, long gone are the attempts of him referring to Katsuki as “Dynamight” in a setting such as this.
“Hey, nerd,” Katsuki says with a nod. “The brats giving you a hard time?” He mutters, glancing around at the rows of students.
Izuku rolls his eyes with a chuckle, waving his hand in dismissal at Katsuki’s question. “Never,” he says fondly, looking at his students before him. Katsuki crosses the floor, his destination being Izuku’s office chair behind his desk.
“Go on, don’t mind me,” he gruffs, his ass coming into contact with the uncomfortable rolling chair. He places the bento on Izuku’s desk, then kicks his feet up to rest on top of the desk. Izuku has scolded him a hundred and one times; and Katsuki lives for it.
Bringing his arms above his head, he folds his hands and places them behind his head for support. Now that he’s all situated, he chances a glance up at Izuku; and the sight that he’s met with sends a shiver down his spine.
Izuku’s glaring down at him, his best ‘teacher look’ of reprimanding nature painting his expression. His eyes linger on Katsuki’s for a brief moment before they travel down to his legs, his gaze searing into the rubber of Katsuki’s combat boots. His expression shifts–like he’s disappointed in Katsuki. Disgusted, even. It makes Katsuki’s blood feel as though it’s a thousand degrees as it shoots down, down, down between his legs, his thighs squeezing together beneath the heat of his gaze.
Then, Izuku’s eyes drag back up to meet Katsuki’s, and he mouths a firm “later.” Katsuki rolls his eyes, but it’s just a facade. He’s actually holding on to the promise of a reprimanding once the brats are dismissed for lunch, if he’s being honest. He could go so far as to say that he’s looking forward to it, even.
Izuku turns back towards his students, his signature soft smile returning to his face as he continues his lesson.
Not even five minutes of staring at Izuku’s back passes before the bell rings and the students begin to pack up their things. Izuku sends them off with a toothy-grin and a reminder for the test that they’ll have tomorrow, shutting the door once the final student saunters out. To Katsuki’s surprise, Izuku locks the door before turning back towards Katsuki.
With his feet still resting upon the desk, he meets Izuku’s gaze. “Ready for lunch?” He asks, in an attempt to rile Izuku up even more. He hates when Katsuki avoids the problem at hand. Which, funny enough, is exactly what Izuku’s done countless times throughout his life.
Including what he’s done with the feelings he and Katsuki share.
Most of his life has been intertwined with the nerd; he’d have to be a complete fool to not notice the swirl of feelings that seep out of his edges from time to time. Izuku’s got a good lock on them, he can certainly give credit where credit’s due. Though, he’s not keeping as tight a lid on them lately as he has over the last few years. The subtle touches, the passing glances; the warm, adoring smiles… Katsuki’s aware that he must feel something for Katsuki.
What exactly that something is, he’s not sure. He’s just hoping it’s somewhere in the realm of a form of attraction, at the very least.
Izuku crosses the floor, his gaze locked on Katsuki as he comes to a halt next to him. “You know you’re not allowed to defile the desks with your boots, Katsuki,” he spits, his voice firm and unwavering as he wraps a hand around Katsuki’s ankle that’s resting on top of his other. “Let alone defiling my desk with your disgusting boots,” he chastises, yanking Katsuki’s foot off of the desk. His other leg follows suit from the sheer force of Izuku’s pull, his breath catching in his throat as he swallows down a moan at the rough handling.
His boots clunk down onto the tiled floor, the office chair turning to face Izuku in the process. Katsuki barks a laugh, a smirk tugging at his lips as he sizes up Izuku. He’s quite upset about this today; maybe he’s having a shitty day. Katsuki should only fuck with him a tiny bit.
“Since defiling the desks with my boots is off limits, are there any other acceptable ways to defile them?” He says with a wicked grin, his hands moving to rest on the armrests of the office chair. He grips the armrests, using them as leverage as he pushes himself up into standing. “Let’s see how else I can defile them, shall we, Sensei?” He purrs, watching in real time as Izuku’s cheeks flush a deep crimson. He always got a bit flustered when Katsuki called him that, and Katsuki loved it. It fueled his kink and made Izuku blush and babble like a nervous idiot. A perfect scenario.
“Katsuki,” Izuku says firmly, his hand reaching forward to wrap around Katsuki’s wrist. “Don’t you dare fuck with my desk,” he says lowly, his tone dark and dominant–it sends a wave of heat over Katsuki’s body.
“And what if I do? You gonna punish me, Sensei?” Katsuki asks with a teasing grin. The rage in Izuku’s eyes makes his stomach swoop, his thighs instinctively squeezing together slightly as he feels his cock throb. He knows he should stop poking the bear, Izuku could easily lay his ass out right here on the tiled floor of UA if he wanted to. This is usually about as far as he takes his teasing anyway, so there’s no harm in just calling it quits here for the day.
There’s always tomorrow to bother the nerd.
His lips part, his lungs drawing in breath as he prepares to apologize when Izuku’s grip on his wrist tightens. “Yeah, I will,” he says, his expression shifting. Now, he’s looking back at Katsuki as if he were a piece of meat, his tongue gliding out to lick along his lower lip.
Katsuki’s eyes widen, his body freezing in place as he stares back at Izuku. This is a new development in their dynamic. He’s teased Izuku countless times about putting his boots on the desks; and it’s never gone this far before. Izuku usually replies to his question of punishment with “no, I know Kacchan’s just being a smartass,” and then Katsuki punches him in the shoulder, Izuku laughs, and they eat their lunch together.
“What?” Katsuki squeaks out, his eyes locked on Izuku’s. The feral grin Izuku cracks is akin to one of a predator that’s finally caught its prey, his body moving to cage Katsuki in; his ass forced to press against the edge of the desk as Izuku crowds his space.
“I said,” he starts, his hand releasing Katsuki’s wrist. “I’ll punish you, Katsuki. Is that what you want? Is that why you’re always such a brat to me?” He grins, a knowing look washing over his expression as he examines Katsuki’s face. No doubt his cheeks are flushed a deep red, his lips are parted slightly and he’s practically panting as Izuku presses forward, into Katsuki’s space.
“You come in here, disrupt my class, put your grimey boots on my desk and talk back to me like it’s your job,” he says aloud, emerald eyes searing into ruby reds. “I have no other explanation for that; other than that this is what you’re into. You get off on this, somehow. Am I right?” He asks, tilting his head slightly to the side.
Katsuki doesn’t know what to do. He’s definitely been caught, and his mind is going a mile a minute as he tries to find a way to do damage control here. He could shove Izuku off of him with ease, tell him he’s being fucking weird, then storm off like some emotionally constipated asshole–or, he can just go with the flow. See what happens.
There’s also a million other scenarios that Katsuki could play out–but he’s feeling rather incapacitated with the growing hard on between his legs. These two seem like the best options to his needy, horny, selfish brain.
So, what does he do? He fucking nods.
Izuku’s eyes widen slightly, and then his grin widens. “I knew it,” he says lowly. “What does it for you? The public aspect? Like an exhibitionist? Or is it the classroom setting? I’m not entirely sure what the classroom setting could be doing for you, but I suppose it wouldn’t be completely out of the realm of possibilities–mmf!”
Katsuki finally finds his physical strength and raises his arms, clamping his hands over Izuku’s motormouth. His cheeks are burning, his eyebrows furrowed as he squeezes his hands over Izuku’s mouth. “Shut it, Izuku,” he growls. Izuku looks back at him with a bored expression, and then Katsuki feels something warm and slimy glide across his palm.
“You’re disgusting," he spits, pulling his hands back and wiping his wet hand on the front of Izuku’s dress shirt.
“Tell me, Kacchan,” Izuku presses, leaning into his space once again. “What gets you going? I deserve to know–you’ve been coming in for months! Getting all hot and bothered without my knowledge,” he says with an overdramatic pout.
Katsuki rolls his eyes. “You’re acting like I cheated you out of something,” he scoffs.
“You did!” Izuku exclaims. “You’ve been here, with me, horny–and I haven’t been able to touch you! That is cheating me out of something,” he pouts, straightening his back out. He crosses his arms over his chest, holding his pout. “It’s not fair.”
Blinking, Katsuki’s at a loss for words. He’s baffled, to say the least. All he can do is stare at Izuku for a few moments, his brain trying desperately to compute what just came out of Izuku’s mouth.
“You’re fucking with me,” Katsuki says, narrowing his eyes. “I’ll kill you, Izuku. Don’t fucking play with me,” he warns, jabbing a gloved finger into Izuku’s broad chest.
“I’m not,” Izuku says instantly, uncrossing his arms in favour of raising them in surrender. “I want you,” he says matter-of-factly. “Just didn’t think you wanted me. So I kept it as what it was–a fantasy,” he shrugs, dropping his hands as Katsuki withdraws his finger.
He’s gotta be dreaming. On one hand–this is too good to be true. On the other–he’s fucking pissed. You mean to tell him that it was this fucking easy?!
All he had to do was fucking coax the information out of the nerd? Which, he could’ve done, by, y’know, opening up about his own feelings.
“I want you,” Katsuki says, his resolve dissipating. “So fuckin’ bad, you have no idea. And I actually, uh, have a thing for teachers. But just you, really. M’not sure what it is, but watching you teach and being on the receiving end of your reprimanding…” he trails off, taking a deep breath in order to calm his hammering heart. “It drives me fucking crazy,” he breathes, a smirk tugging at his lips.
Izuku stares at him for a moment, and then he’s tipping his head forward. “Fuuuuck,” he groans, big, strong hands finding Katsuki’s hips. The touch sends electricity through his body, his own hands moving to rest on Izuku’s shoulders. “So you, like, actually want me to punish you?” He asks, peeking up at Katsuki through curly bangs.
“Yeah,” Katsuki says with a nod. No reason to lie.
The hands on his hips squeeze, another groan filling his ears as Izuku’s fingers dig lightly into the plush flesh of Katsuki’s curves. “That’s so hot, Kacchan,” he whines, lifting his head to meet Katsuki’s gaze. Then, the hands on his hips spin him around, the front of his upper thighs pressing into the wooden desk as one of Izuku’s hands slides up his back. The hand stops in the middle of his shoulderblades–and then he’s pressed down, his chest meeting the top of the desk; Izuku holding him in place. The air is knocked out of his lungs as he’s manhandled, his head beginning to feel as though it’s stuffed full of cotton. He feels light and airy; like if Izuku were to release his hold on him, he’d float away into the ceiling.
“For your punishment, I’m going to give you ten spankings,” Izuku explains, his tone firm and unwavering. “If that’s not something you’re comfortable with, tell me now,” he says, giving Katsuki the opportunity to stop the whole thing. It’s invigorating, honestly. He’s giving up physical control to Izuku, yet Izuku is returning the control in a way that makes Katsuki’s heart pound.
He shakes his head, his chest heaving against the wood as he tries to catch his breath. “Give it to me. I was bad, Sensei,” Katsuki says with a slight sway of his hips. Izuku groans, and then he shifts behind him. The hand on the back of his shoulderblades slides down to the small of his back, his other hand resting firmly on Katsuki’s ass.
“I want you to count,” he says, his hand giving Katsuki’s ass a firm squeeze. “Every time. Got it?”
Katsuki nods, a soft “yes, Sensei,” slipping past his lips.
“If you want to stop, say pepper. We’ll stop instantly,” Izuku says, his hand keeping contact with his ass. “Understood?”
“Yes, for fuck’s sake,” Katsuki whines, shimmying his hips in impatience.
In a split second, Izuku’s hand is drawn from his ass. Then, he hears the swish of Izuku’s hand swinging through the air. He doesn’t even have the time to prepare for when his broad palm strikes his ass. It’s not hard enough to make a loud noise–especially with the extra padding his hero suit provides–but it’s certainly hard enough to have his body bouncing forward against the hardwood of the desk, his eyes opening wide as he gasps.
“That was an extra, for being such a brat,” Izuku spits, his tone laced in pure venom as he rubs his hand soothingly against his ass. The slight sting begins to subside instantly, his hips pushing back slightly into the touch. “The next one, I better hear you count.”
“Yes,” Katsuki says, breathless.
“Yes what?” He says, his hand on his lower back pressing down harder.
Katsuki’s mind blanks for a moment, and he’s half-expecting to have just cum in his pants. That didn’t happen, though. He just couldn’t think at that moment; his entire being was floating in a pleasure-filled limbo.
Just as quickly as he blacked out, he came back to.
“Y-yes, Sensei,” Katsuki stutters out, his hardening cock trapped beneath him, against the desk.
A pleased hum rumbles out of the man behind him. “Good boy,” he praises, his hand drawing back once more. The anticipation boils inside Katsuki’s veins, his lower lip finding itself trapped between his teeth as he waits with bated breath for his punishment.
Then, just like a glorified miracle, Izuku’s hand smacks the curve of Katsuki’s left asscheek. He does his best to stay quiet, he really does, but a low moan is ripped out of him as his blunt teeth dig into the plush flesh of his lower lip. He sucks in a few breaths through his nose before he releases his lower lip.
“One,” he counts aloud, his breath coming in quick, deep bursts as he awaits the next smack.
It comes immediately after, but on his right cheek this time.
“Two,” he counts, his pulse thumping in his cock.
Another smack, alternating cheeks.
“Th–three,” he gasps softly, the friction to his cock from his jolt against the desk scrambling his mind momentarily–then, another smack pulls him back to reality.
“Four,” he says, doing his best to keep his voice down. He has to remember they’re in a school, he can’t get them caught–smack.
“Five,” another soft gasp, his cock begging to be humped against the desk. He thinks about whether he could get away with grinding himself against the top of the desk or not–then; smack.
“Si–six,” he breathes, deciding ultimately that that was his sign not to.
Another smack.
“Seven,” he says, drool dripping from the corner of his lips, creating a small little pool on the surface of the desk beneath him.
His eyes roll back as another smack lands on his ass.
“Eight,” he moans lowly, his palms slick with sweat inside his gloves.
Smack.
“Nine,” a dreamy sigh, his ass stinging deliciously as he mourns the fact that the end of their little scene is quickly approaching–smack!
It’s harder this time, as if Izuku really put his back into it this time. It sends lightning bolts through Katsuki’s entire body; the new-found-realization that Izuku could really do some damage back there if he were to give it his all. He could mark Katsuki up good; cover him in his handprints like a work of art, created by his own hands.
“Ten,” he moans, unshed tears finally beginning to overflow from pleasure. They track down his flushed, blotchy cheek in thick rivets, dripping down onto the desk as his turned head faces the door to the classroom.
“I knew you could be a good boy, baby,” Izuku purrs, his hand rubbing soothingly against his sensitive skin. Katsuki desperately wishes to feel those hands on his bare skin–against the heat of his vulnerable body. The thickness provided by his hero suit pants and his boxers actually breaks his heart.
He’s not sure what washes over him, a sob wracking over his body, his mind spiraling as he yearns to be touched by the man behind him; without clothes. Instantly, Izuku’s hands move. They find his shoulders, pulling Katsuki up into standing. He holds him up, which Katsuki is grateful for because if he wasn’t, he’s sure he’d have fallen to the floor as Izuku turns him to face him.
“What’s wrong, Kacchan?” Izuku asks, panic filling his tone. “Was it too much? Did–did I go too far? I’m so sorry, Kacchan–”
“No,” Katsuki says, shaking his head as tears continue to fall down his cheeks. “I–I really liked it! I want y-you to do it again, but–hic–but, actually touching my skin,” he sobs, wiping his eyes with his balled, gloved fists.
Izuku’s silent for a moment, and then he’s wrapping his arms around Katsuki’s waist, pulling him flush against his chest. “Oh, baby,” he coos, rubbing his hands soothingly up and down the expanse of Katsuki’s back. “Are you worried we won’t do this again?”
Katsuki’s face dips into the crook of Izuku’s neck, and he nods. He doesn’t know one hundred percent why it’s happening, but he’s aware he’s dropping. He didn’t think he’d drop on their first “scene,” but he supposes it’s not completely out of the realm of possibilities.
“Don’t be so silly,” Izuku says softly, nuzzling his face into Katsuki’s hair. “We can do this whenever Kacchan wants. I really enjoyed it. I would be honoured to do this with you again–to do anything with you again.”
Tucked in his warmth, his strong hands rubbing his back so gently, his soft words filling his ears; Katsuki begins to reel himself back in. His heart hurts less. His eyes stop producing new tears. His hands clutch at the front of Izuku’s button up.
He shifts his weight on his feet, his ass accidentally bumping into the edge of the desk. He sucks a sharp breath in quickly, his mind quickly melting back into that comfortable, familiar buzz as the dull pain melds into pure pleasure.
“M’kay,” he mumbles, inhaling the scent of Izuku’s cologne. “I’d really like that. Please.”
“Of course, baby,” Izuku says, his tone dripping with adoration. “If you wanna meet me out front after school, we can go back to mine and talk about everything. And maybe we can try something else, if you want. Or we can just hangout and cuddle! I’m happy with anything as long as it’s with you, Kacchan,” he coos, squeezing Katsuki tight in his hold before loosening his grip. He pulls back, just enough for them to come eye-to-eye.
Katsuki nods. “I’d like that,” he says, a soft smile tugging at his lips. His brainfog begins to fizzle out, his mind clearing more and more with each passing moment. Logically, subspace can’t really last too long right now, given the circumstances. He still has to finish patrolling.
“Do you need anything for your butt, baby? Or you think you’ll be alright until tonight?” Izuku asks, his hands sliding down to rub soothingly over his hips. “I don’t really have anything with me to help the sting,” he whines, looking at Katsuki with a pout. “But I’ll definitely take care of you tonight! I promise!”
“S’okay, Izuku,” Katsuki says, giving him a soft smile. “I’ll survive until tonight.”
Izuku studies him for a moment before he nods. “Okay,” he says, his hands giving Katsuki’s hips one final, gentle squeeze before they pull away. Izuku’s eyes flicker up to the clock behind Katsuki; the one at the back of the classroom that he uses to pace himself during his lectures. With a gasp, he moves quickly–grabbing the bento and opening it as ungraceful as possible. He grabs a half of one of the sandwiches Katsuki made for them and brings it up to Katsuki’s lips.
“Eat,” he instructs. Katsuki instantly obliges, dropping his jaw and allowing Izuku to push the sandwich into his mouth. He takes a bite, chewing and swallowing before Izuku presents it to his lips again. They do this back and forth until Katsuki’s eaten the entire sandwich, a handful of grapes and a few baby carrots.
“I have a class in five minutes, but I wanted to make sure you ate. I promise I will eat after my next class–I have a fifteen minute break!” He says, closing up the bento. His sandwich is still in there, and he’ll definitely eat the remaining grapes and baby carrots.
“Fine,” Katsuki grumbles. “But I’m checking the bento when I meet you after school. And I’m telling Aizawa on my way out to make sure you eat,” he says, poking Izuku’s shoulder.
“Ahh, Kacchan’s so caring,” he sighs dreamily, his expression softening as he looks back at Katsuki. It makes Katsuki’s stomach swoop.
“Yeah, yeah,” he grouses, rolling his eyes. “I’ll see you later.”
He goes to turn towards the door when a hand comes up to cup his cheek, turning his face back towards Izuku. The nerd leans in, pressing his lips against Katsuki’s for a few brief moments before he pulls away.
“See you, Kacchan. Be safe,” he says warmly, his smile small and soft and so full of fucking love.
“See you. I will be,” he manages, his entire nervous system going into hyperdrive from a single pressing of their lips together. He can taste his heartbeat at this point. “You be safe, too.”
Izuku nods, then Katsuki turns and heads for the door. He unlocks it, sliding the door open before stepping out into the hallway.
He doesn’t chance looking back, because if he does he’s almost certain he’ll just abandon the whole second half of his patrol. So, he walks out the door, leaving it open as students begin to file past him.
The walk through the halls this time is pure euphoria. His ass stings with every bounce as he walks, his chest feeling warm and fuzzy as he makes his way to the entrance. He stops by the teacher’s lounge, making good on his promise to ask Aizawa to make sure Izuku eats after his class. The grump agrees, sending Katsuki off with an unenthusiastic peace sign.
Stepping into the fresh air, he fills his lungs with as much of it as he can. He exhales with a chuckle, shaking his head in disbelief.
What a turn of events. He can’t wait for tonight.
—
Katsuki finishes his patrol at five o’clock on the dot. Paperwork is done, he’s showered and changed out of his hero costume as he makes his way towards UA for the second time today.
He drives there, so it takes all of eight minutes before he’s pulling up to the front of the school. He puts the car in park, and is about to get out and greet Izuku when his passenger door swings open.
Turning his head, he watches in surprise as Izuku plops himself into his passenger seat. He pulls the door shut, then turns to face Katsuki. He leans into his space, a hand coming up to cup the back of Katsuki’s neck as he pulls him towards him; pressing their lips together. Katsuki allows himself to be guided, melting into the kiss instantly. Their lips linger together for a few moments, then Izuku pulls back slightly.
“Hey baby,” he says, grinning. “Missed you. Thought about you all afternoon—I’m so excited, I literally packed up and left the second I finished grading quizzes after my last class.”
He presses their lips together again, humming into the kiss. Pulling back, he also retracts his hand from the back of Katsuki’s neck. He misses the contact instantly, a pout forming on his lips as he scrunches his nose.
He wants more.
But he needs to be patient. He’s waited long enough… he can handle a little bit longer.
With a small smile, he shifts the car in drive. He asks Izuku how the rest of his day went as he sets the car in motion, and the sound of Izuku’s voice fills his ears as he heads towards Izuku’s apartment.
—
They rode in comfortable conversation the entire way to Izuku’s place; Izuku kept it light, talked about his day. He asked Katsuki about his, commenting on a retelling of events Katsuki did involving a low level thug that he caught attempting to rob a bank. Simple shit.
Katsuki pulled the car into the underground parking of Izuku’s apartment building; navigating his way into the guest parking at the very front by the elevators. Once the car was parked, both of them slid out of the car and headed towards the elevators. They made their way up to Izuku’s floor, down the hallway all the way to his apartment’s front door.
Izuku unlocked the door, pushing it open and walking inside. He reached back, grabbing Katsuki by the front of his shirt, and pulled him inside. The door shut behind him and then his back met the back of the door, his lips parting in surprise. Izuku wastes no time, breaching his personal space as he crashes their lips together. His eager tongue slips past Katsuki’s lips instantly, licking into his mouth with a fervor that makes Katsuki’s head spin.
Big, strong hands are on his body–roaming from his hips to his sides, to his chest and back down to his ass. They cup Katsuki’s ass, a soft gasp ripping from his lungs from the sensitivity. Izuku guides him with the hands he has on his ass, stepping back from the door. Katsuki’s feet follow Izuku, his arms wrapping around Izuku’s shoulders for more support.
He’s led into Izuku’s room; he knows that because the smell of his favourite coconut-vanilla scented candle hits his nose the second they walk through the doorway. Izuku only ever kept that candle in his bedroom. Even unlit, it manages to fill the room with the most luscious coconut scent.
A few more steps and the backs of Izuku’s knees must’ve hit the edge of his mattress because he plops down, pulling Katsuki with him. Strong hands move from his ass to his hips, guiding Katsuki on top of him as he scoots slightly up the bed. Katsuki’s knees dip into the bed one after the other as he crawls on top of Izuku, his knees straddling Izuku’s outer thighs.
Panting, Izuku separates their lips, a few centimeters between them as he looks back at Katsuki. “I know I said we could talk, Kacchan,” he starts, attempting to catch his breath. “And we can, I just–I couldn’t help myself. I’ve been imagining this day for so long.”
Katsuki’s eyes flicker from Izuku’s emerald orbs down to his spit-slicked lips, then back up to his gorgeous pools. Talking is great–they definitely need to do that. Right now, though, Katsuki’s so fucking hard. He was practically denied an orgasm earlier… talking can come after he blows his load.
“We can talk after,” he says, pressing forward. He presses his lips against Izuku’s, then moves to pepper slow, open-mouthed kisses to the curve of his jaw. “I was bad today, remember?” He says between kisses, his path leading him to the space just below Izuku’s ear. “I need a proper punishment, Sensei,” he purrs in Izuku’s ear, his lips pressing gently against the shell. He feels Izuku shiver beneath him, his stomach swooping as Izuku’s fingers dig into the plush flesh of his hips.
Then, in the blink of an eye, Izuku’s hand snakes into Katsuki’s hair. His fingers grip blonde roots at the back of his head as he yanks his head back. A low moan slips past his lips, his eyes half-lidded as he looks at Izuku.
“You’re right, how foolish of me,” Izuku hums, his grip tightening in his hair. “Delinquents need extra punishments, right? In order to remind you of where you belong,” he coos, his tone sickly sweet, dripping with venom. It’s almost mean.
Katsuki nods his head, his cock aching in his sweats. He wants nothing more than to be put in his place–by Deku Sensei, specifically.
Izuku scoffs, his expression darkening. Then, he yanks Katsuki to the side by his hair, his grip loosening as Katsuki’s body is tossed onto the mattress. The air is knocked out of him in surprise, his lower lip getting pulled between his teeth as he suppresses a moan. After all his years of being the bully… he’s about to cream his fucking pants from being on the receiving end. But only because it’s Izuku.
No way in hell he’d put up with this treatment from anyone else. Izuku is the only exception. Always has been.
“Take your clothes off,” Izuku instructs, rising from the mattress. He stands at the edge of the bed, his arms crossed over his chest as he looks down at Katsuki. “Now.”
Katsuki swallows excitedly, then gets to work. He does as he’s told; ridding himself of each article of clothing that adorns his body. He saves his boxers for last, hooking his thumbs beneath the waistband as he keeps his eyes locked on Izuku’s. He shimmies out of them, sliding them down his calves and kicking them off his feet. They land somewhere over the edge of the bed, and Katsuki’s skin feels as though it’s been lit ablaze. Izuku’s gaze is searing, his eyes darkening as they roam along the expanse of Katsuki’s nude body. His eyes linger on Katsuki’s cock, his tongue gliding out to lick along his lower lip.
Glancing down, Katsuki’s eyes widened at the massive bulge in Izuku’s slacks. His hand moves to grip his clothed erection, causing Katsuki’s jaw to drop slightly in surprise.
“On your knees, ass in the air,” he groans, his hand palming at his erection. Katsuki takes one final look before he turns onto his stomach, positioning himself on his knees. He spreads his legs; his knees about shoulder-length apart as he rests his forearms on the mattress, his elbows the same width apart. He drops his head, resting his cheek on the mattress as he looks at Izuku.
The sight alone sends a jolt of electricity down his spine, his cock twitching between his legs. Izuku has undone his belt and unzipped his slacks, his hand is shoved in his boxers as he strokes himself lazily to the sight of Katsuki. His cheeks are flushed a deep crimson, his eyes practically filled with hearts as he stares at Katsuki’s ass. No doubt, the flesh of his ass is still slightly red, possibly even beginning to lightly bruise, from their interaction earlier today.
Katsuki’s tongue pokes out, licking along his lower lip as he watches Izuku. Then, his hand stills. He removes his hand from his boxers, his thumbs hooking beneath the waistline of his slacks. He shoves them down, stepping out of them before climbing onto the bed behind Katsuki.
“You’re so beautiful,” he says softly, his hands finding Katsuki’s hips in an instant. “Your skin is still red–so beautiful,” he sighs dreamily, his right hand sliding down to graze the reddened skin. Katsuki gasps, sensitive to the touch.
“I’m going to give you ten real spankings. If you want to stop, say red. Got it?” Izuku rasps, his hand squeezing the right globe of Katsuki’s ass.
“Yes, Sensei,” Katsuki says, biting back a moan. The anticipation kills him as Izuku draws his hand back.
“Count aloud, just like earlier,” he says, his left hand holding Katsuki in place at his hip. “M’gonna see how many different shades of red will bloom across your gorgeous skin.”
He hears the sound of Izuku’s palm coming into contact with his ass before he feels it, the loud smack! ringing in his ears as he jolts forward. A heady moan escapes him, his jaw dropping open as the pain spreads deliciously across his already sensitive skin.
“One,” he pants. That spanking was much harder than the ones Izuku gave him earlier.
His hand draws back, then drops back down onto the same cheek.
“Two,” Katsuki chokes out, the sting increasing tenfold from the repeat cheek.
Izuku draws back, dropping back down onto the same cheek again.
Tears prick along Katsuki’s lower lashline as he gasps, his right cheek radiating intense heat as the pain blooms along his flesh.
“Th–three,” he groans, his cock jumping from the increased pain. He’s surely leaking precum onto the mattress beneath him.
Another draw back, another smack to his right cheek.
“Four,” he sobs, unshed tears beginning to overflow. He soaks the sheets beneath his head with his tears–but those droplets are full of nothing but pure pleasure.
Izuku doesn’t even falter. He withdraws, then reins down a storm of pleasure and pain upon Katsuki’s right cheek.
“Five.”
Another smack. Same cheek.
“Six.”
Repeat.
“Seven.”
Repeat.
“Eight.”
Repeat.
“Ngh–nine,” he moans, his skin numbed from the intense punishment. He’s begun to drool onto the mattress, his eyes half-lidded as he rocks his hips slightly. His mind is fuzzy; as if the space between his ears was stuffed with cotton instead of his brain. A light buzz vibrating throughout his entire body as he succumbs to the pleasure.
Izuku draws his hand back once more before bringing it down on his right cheek, a choked moan pulled from Katsuki as he jolts from the sheer force. His eyes roll back, his thighs shaking as his cock twitches; so painfully hard between his legs, swaying from the jolt.
“Ten,” he pants, chest heaving as he swallows hard. The sheets beneath his head are covered in a mess of his tears and drool, his hands white-knuckling the soaked fabric. Izuku’s hand comes down once more, but it’s a soothing touch that rubs softly against Katsuki’s sensitive skin. On the surface, it burns–but beneath, it burns for a whole other reason. Izuku’s hand, the one that caused so much pain, is soothing him, as best as he can.
A dopey smile forces its way onto Katsuki’s face, his hips pressing back into Izuku’s touch as he lets himself drift further and further.
“You did so good for me, baby,” Izuku coos, his lips pressing gently in the middle of Katsuki’s lower back. “Lay down, angel. Let me take care of you,” he says softly, guiding Katsuki’s legs to kick out straight behind him. He plops down onto the mattress, as ungraceful as possible, and lets Izuku fuss over him. Lets Izuku take care of him.
Izuku climbs off of the bed, pressing a quick kiss to the side of Katsuki’s head before heading off towards the bathroom. “Grabbing the first aid kit, baby,” he calls over his shoulder.
Katsuki hums in response, the buzzing in his body nearly lulling him to sleep as he waits for Izuku to return. When he does, Katsuki feels the mattress on either side of his thighs dip. Then, he feels Izuku’s weight settle comfortably over the backs of his thighs.
“I’m gonna clean you up, okay? Probably gonna sting, but I need you to be brave, baby. Okay?” He says softly, the sounds of packaging ripping and a bottle opening hitting his ears.
“M’kay,” Katsuki mumbles, bracing himself for the sting.
“Here I go,” Izuku says, a comforting hand resting on the small of his lower back as his other hand presses the cleaning solution to his right cheek. It must be on a cotton pad of sorts, because the material isn’t as irritating as he’d expected. He sucks in a sharp breath, gritting his teeth as the sting begins to fill the expanse of his damaged skin.
“You’re doing so good, Kacchan,” Izuku praises, working quickly. He disinfects Katsuki’s ass, then fans it dry with his hand. Then, there’s a cool cream rubbed over his sensitive skin. “This will temporarily numb your skin. It’ll help the pain,” he says, gently rubbing the cream into his skin.
Once he’s all done, he packs up the first aid kit, placing it off to the side. He moves, positioning himself off to Katsuki’s side. He lays next to him, propping himself up with his elbow, his head resting in his hand as he runs his fingers through blonde roots.
“How was that, Kacchan?” He asks, his fingernails gently scratching against Katsuki’s scalp.
“S’nice. Really nice,” he hums, leaning into Izuku’s touch.
Izuku chuckles before leaning forward, placing a soft kiss to Katsuki’s forehead. “I got you pretty good. Your skin is all types of gorgeous shades of reds and purples,” he says, his expression softening as he looks at Katsuki. “I’ll reapply the cream as many times as you need. In order to do that, you need to stay with me tonight.”
“Okay, baby,” Katsuki sighs happily. He shifts his hips slightly, hissing when his cock rubs against the sheets.
“What’s wrong?” Izuku asks, sitting up.
“Nothing–I’m just,” Katsuki starts, sucking in a breath. “So, uh, hard. Needa cum,” he mumbles. His cheeks feel hot as he blinks up at Izuku.
“I can help with that,” Izuku says instantly, nodding his head. “You were so good for me, baby. You deserve a reward,” he smiles. “How do you want me?”
Katsuki ponders the question for a moment, then he grins.
“Can you fuck my face, first? Then, if I don’t cum from that, just jerk me off?” He asks, his grin feral. “We’ll fuck when I’m a bit more healed.”
Izuku’s eyes are wide as he lips part in shock, his cheeks flushing a deep crimson as he computes what Katsuki just said. Then–he’s nodding furiously, reaching down to slide his boxers down his legs. His cock springs free, smacking against his abs. Drool fills Katsuki’s mouth, his feather-light body sliding off the bed in favour of resting on his knees on the floor. He drops his jaw, parting his lips for Izuku’s cock.
With a groan, Izuku pushes himself off of the bed. He grabs Katsuki by the jaw; and Katsuki’s mouth is filled with Izuku.
He fucks his face like he’s nothing but a toy for him to use, a fleshlight that he abuses as he chases his orgasm. Katsuki’s dick is like a magnet for his hand at this point, and it only takes like four pumps before he cums all over his hand and thighs, his moans vibrating Izuku’s cock as he fucks his throat.
Izuku cums shortly after, filling Katsuki’s throat with his spend. Then, once his cock slips out of Katsuki’s mouth, he drops to his knees. His hand finds Katsuki’s spent cock, working it back to full hardness in under two strokes. Katsuki moans, a babbling mess as he cums again.
Then, he’s hauled up onto the bed, boneless as he’s maneuvered on top of Izuku’s chest. Chest to chest, Izuku wraps his arms around his waist. The sound of Izuku’s heart beat lulls him to sleep shortly after.
They definitely have a lot to talk about in the morning.
