Chapter Text
There’s this… tension , building up inside Katsuki.
It’s been bothering him for a few days now, since that incident with Deku, itching under his skin and keeping him up at night. His broken body didn’t even allow him to twist and turn in bed, all he could do was stare at the ceiling.
It’s Saturday noon and Katsuki is finally alone in his room; Deku went out to hang out with his nerd friends, leaving him to rot in bed and get bored of his mind.
For the first time ever, Katsuki regrets finishing his homework so early. He needs a distraction, from Deku, and this room, and the stiffness of his own body after laying in bed for so long. He needs to feel something different.
He slides his good hand laying on his stomach down his abs, gliding it tenderly so it grazes and titlates his skin. This is just what I need, he realizes —with Deku here all the time he couldn’t even entertain the thought of touching himself, but now…
Pleasant goosebumps bloom on his skin as he moves his fingers across his chest, caresses over his waist, palms himself down his belly button…
and bumps into the fresh diaper.
“Goddamn—freaking—chastity belt,” he curses and groans, getting even more frustrated. Deku would know if he opened the diaper, and ask questions about it too.
Still, the tingling under his skin continues, and the tension building up in his lower guts calls to be resolved, so Katsuki decides to finish what he barely started. He can do it, he just has to be sneaky.
With some effort, he rolls onto his stomach, his face resting on the pillow.
Rolling his hips slowly, he grinds on his bed through the diaper that shifts with him and makes a soft crinkly sound. It’s not as intense as fisting his dick, but the gentle friction stirs a low heat in his belly
“F—fuck,” he gasps softly, barely whispering as he tightnes of the diaper rubs against his dick, biting his lips. He has a bad feeling about this, like he’s doing it wrong, or something bad is going to happen… but he shouldn’t need to be so quiet—nothing bad can happen to him in the bed, and no one is here to judge him for his unconventional masterbation methods.
He grabs one of the pillows from his bed and places it under his crotch, giving himself a mass to thrust against, and picks up the pace of his hips.
Shit, it feels so good ! His dick is burning, shocked with pinpricks of pleasure running through him and conducted by the friction. The diaper turns out to be the perfect thing to grind against; it’s soft and pillowy, enveloping his dick completely and helping to relieve the tension in his dick from the sides too.
He humps the pillow with vigor now, and it still doesn’t feel like it’s not enough—he needs more, needs to be touched—
He thinks about Deku pressed against his ass, and what it might feel like Deku was on top of him now?
“Hell no, not Deku, not now,” he huffs. What if Deku could see him now, mounting his own pillow like a desperate dog?
For some reason, the thought doesn’t turn him off.
He pants and gasps, salivating on the pillow sheet from how out of control he’s getting. His hips thrust on their own accord now, fast and erratic, making his diaper a loose mess—the cushioned layer is moving with him now, half open and moist with precome that smooths the raw friction.
He puts his good arm on his ass, squeezing it and spreading his cheek. He’s so close—he’s gonna nut in his stupid fucking diaper but it feels too good to stop—
“Bakugou!! We came to hang out with you!”
There’s a loud knock on his door, startling him and completely ruining his orgasm.
“Fuck me!!” He yells into the pillow, his heart beating hummingbird fast.
“Aww don’t be like that, we missed you Bakubro! ”
He uses his good arm to hoist his torso and quickly roll and lay on his back without hurting himself.
“Get lost extras, I’m busy!”
“That sounds like Bakuspeak for ‘I missed you too’!”
The door slams open, and Kirishima, Sero, Mina and Kaminari come waltzing in.
“I know you told us not to come visit you but it’s Saturday and I know you must be bored as hell, laying in bed all day and not blowing off your excess energy,” Mina says loudy, propping herself on Katsuki’s changing table and making him cringe. Luckily none of the diaper stuff is out so they’d never make that connection, but still… he knows .
“I’d rather be bored than annoyed,” he retorts, sitting up and rumpling the blanket to obscure his diaper and the bump of his deflating erection. Anxiety simmers under his skin, and he does his best not to let it show. Why the hell did he ever allow Deku to leave him in his room without pants?!
He never wanted any of his classmates to visit because he doesn’t want to see the pity in their eyes when they see him bedridden… but this is just the worst possible timing. The diaper might definitely crinkle under the sheets, and he already drank a bottle today… What if he leaks and pisses in front of them? What if he stinks?
Kaminari throws a snack that Katsuki fails to catch with his left arm. “We got you those wasabi snacks that only you like. Dig up, we’ve got a whole lotsa other stuff too!”
He opens the bag, unable to stay mad at them for being good friends. They pass some other snacks and sweets around and make themselves comfortable around him.
“You remember how Present Mic told us we’d have to choose a topic to talk about in English in front of the class?” Sero tells him as he opens a bag of sour gummy candy. “Well this week, we finally started doing it. It was a disaster, you’d have enjoyed it so much.”
Katsuki bark-laughs. “What the fuck did you talk about?”
“Well, my strategy was to talk about Shinto. Talking about as much traditional stuff as possible so I can still use Japanese terms, and it kiiiinda worked? But Kirishima made an absolute fool of himself.”
“Yup,” Kirishima pops the ‘p’. “I wanted to talk about martial arts, but once I started, the English names of all the moves and body parts evaporated from my brain, so I decided to just… demonstrate them?”
“He broke the teacher’s chair!” Mina chimes in. “And I’m pretty sure there’s still a fissure on the desk!”
“Pffft, idiot” Katsuki chortles. “It’s not that hard ya know, you should have.. Just use, flashcards…”
Katsuki’s words slow down as he feels something hot and wet pooling between his legs for a moment, before it gets soaked.
He just pissed in front of them, mid sentence .
His mouth feels extremely dry all of the sudden and he licks it, tasting the sweat accumulating above his upper lip.
He shifts in bed, and realizes that his diaper started to slip below his hip on one side—it doesn’t sit as tight as it supposed to because of the humping and he freezes in place, scared the piss will leak onto the sheets.
Why the fuck did he let them in in the first place?!
He takes a deep breath, and waits for this nightmare to be over.
“You’re basically on hold, waiting for Recovery Girl to return, right?” Mina asks.
“Yeah, that old hag is sure taking her time, screwing me over,” he grumbles.
“She travels a lot, actually. Last month Tetsutetsu missed the last few days of the internship because she wasn’t around to fix his leg, it was a huge bummer.”
Katsuki thinks back to Deku saying that it’s common knowledge that Recovery Girls weren't always there to heal their every wound, and students have to stay bedridden until she returns. Have any of his friends ever been… broken, like he is now?
Hot piss leaks down his leg and he feels the sheets sticking to his skin. His stomach rises to his throat as he lays there, urinating on himself.
He texts Deku to come back asap and starts to munch on his wasabi snack, scrunching the bag as loudly as possible.
“How are you and Deku doing okay?” Kirishima asks, as if reading his mind. “I know you guys don’t get along, but I bet you’re in good hands!”
“He treats me like a baby.” He complains, keeping to himself the fact that he means it quite literally.
“Aww, don’t be like that man,” Kirishima tried to cheer him up. “I’m sure he just cares about you!”
Katsuki wonders if Kirishima’s ever been in this kind of miserable situation, when he’s completely depending on someone else to function at such a basic level. He considers asking him, once it’s all over, when they’re alone…
Or never. Probably never.
Suddenly he feels a breeze over his thighs—his blanket is lifted and his knee is exposed, when Sero straightens his elbow to grab a drink.
“Oops,” Sero detaches the blanket from his tape, “loose end.”
Katsuki growls, exposing his teeth. “Get the fuck away from me, and keep your useless quirk to yourself!!”
More piss drops roll down his thigh and he’s absolutely horrified by the possibility that it stains throughout the blanket.
Mina rolls her eyes at him. “Calm down, like you’ve never let out an explosion when you didn’t mean it.”
“I’m gonna blow your face off and absolutely fuckin mean it,” he threatens, raising his arm and propping up to make good on his threat, but as he raises himself he can hear the diaper crinkling.
He freezes in panic, trapped like a caged animal. They probably can hear it too, and if anyone finds out about this, he’s going to kill everyone in this room then himse—
Kirishima touches his shoulder. “Hey, is everything okay? You’re not usually this—”
Suddenly the door slams open, and Deku comes inside, looking deadly serious and catching everyone’s attention. Once he realizes what’s going on though, his face softens.
“—Hi guys! What’s up?”
“Not much, just pissing off Bakugou like usual.” Kaminari whines. “I don’t know how you manage to spend so much time with him!”
“It’s not a walk in the park for sure,” Deku mumbles, eyeing Katsuki. His eyebrow rise slightly in realization. “Funny you mention it… I don’t want to ruin your little gathering, but maybe it’s enough for today? Kacchan gets grouchy when he’s tired.”
“Ohhhh,” they all say, like it makes sense.
They leave their snacks to Katsuki, move his chair back by the desk and leave.
Finally, they’re alone.
“Deku?” Katsuki utters, and his voice already breaks on those two syllables.
“What?”
Tears are choking up his throat, so he doesn’t say a thing. He simply lifts the blanket and shows Deku the utter mess under there.
“ Oh. ”
Deku stares at him, his eyes wide like saucers. It’s only slightly better than the pity he was expecting, but Katsuki still feels his cheeks heating up at the weird look he’s getting.
Yes, he’s been laying in only a pajama T-shirt and a diaper the entire time. Chatting with his friends like everything is normal, while pissing himself like a baby.
“I’m sorry Kacchan, you’ve been…”
“—don’t you dare.” he snarls, slapping Deku’s hand away. “Don’t you dare, I fuckin’ hate this so much. Hiding it the entire time… It was nerve wracking!”
“Shhh, shh it’s over baby. Don’t you worry about it, just let me take care of you.” Deku holds him by the waist and helps him sit upright, looking more like he’s going to devour him than care for him.
Still, Katsuki doesn’t want to be on the dirty bed anymore so he nods, and raises his arm. Deku wordlessly picks him up, one hand supporting his ass and the other wrapped around his back for support…
But he doesn’t move to put him down anywhere. He just holds him in the air, swaying gently from side to side and rocking them both in soothing motions. Katsuki lets him, laying his head on his broad shoulder and hating how dependent on Deku he’s become at the same time.
Deku stretches the back of his diaper to check it—it’s so loose that it easily stretches without any resistance, exposing Katsuki’s cheeks to fresh air.
“What happened to your diaper?” Deku looks at him disapprovingly, like a strict mother.
Katsuki turns his head to the side, unable to look Deku in the eye.
“Did you do something you weren’t supposed to do?”
His tone is low and surprisingly stern, completely catching Katsuki by surprise.
“It’s not my fault… I can’t do stuff…” he mumbles weakly.
Deku nods, rubs his back for a long moment and sighs. “It was fine, I promise. You were so brave.”
“I know,” he says quietly, pressing his entire body closer against Deku’s. It’s easier on his sore body that way, but also… there’s this itch under his skin, a foreign need to be touched, and held, and…
And there’s a stiff bump in Deku’s pants.
Katsuki presses his hips against it experimentally, and silently curses the shiver it wrecks in his body when he does so.
“You must be dying to be washed, right?”
Memories Deku’s terrifying boner from their previous shower together floods Katsuki and shakes his head, scared of being overwhelmed again.
“No shower. Not now, just clean me up and leave me alone!”
Deku hums and takes him to the changing table.
Katsuki finally looks at himself after he’s laid on the vinyl mattress, and cringes internally.
His diaper is a mess; puffy, misplaced and ill-fitting. The left sticker is basically already peeled apart and there’s dark drops of piss on the hem of his shirt, proving the need for a proper diaper in the first place.
But the absolutely most horrifying part is seeing the hard head of his dick poking out the elastic of the diaper, pointing up at his belly like it’s blaming him for his horny sins.
Instinctively he tries to hide it, shoving it back down, but then his erection pokes out of his leg hole, which is even worse. He ends up just covering his piss soaked dick with his palm.
Deku giggles and Katsuki groans, turning his head away. He must look like some sort of a giant pervert baby with it, but he can’t help it.
“Don’t—don’t look at me like this, creep!” Katsuki snarls.
“Don’t worry,” Deku looks at him with a wobbly smile, amused and cunning, and gently removes his palm.
“I can work with that.”
He lifts Katsuki’s legs so his knees fold against his chest—lucky his condition hadn’t hurt his flexibility.
Katsuki protests weakly as his ass is spread, his hole is winking, and his hard cock is hovering between his legs and ass, pointing at Deku and leaking pre. He’s never, ever felt so exposed.
“Wha- what are you doing?! Don’t fold me like I’m some kind of toy!”
“There’s a lot to wipe and clean this time Kacchan, I need to reach areas that the diaper usually keeps dry.”
Deku pulls out a wet wipe and starts wiping Katsuki’s ass. Katsuki can’t see what he’s doing, but the cool sensation of it over his cheeks makes his skin tingle. Everything Deku swipes over feels fresh and new, and his tentative touches feel like some sort of massage over his delicate privates, relaxing and titalting at the same time.
Deku replaces the wipes with new ones, wrapping one of them around Katsuki’s dick while he takes the other and wipes down Katsuki’s crack, until he sinks into the dent of his rim. Katsuki gasps sharply when he feels a little poke, just the tip of a finger inserted—then removed. Deku replaces the wipe, wraps it around his finger and pushes past the knuckle this time.
“Oi. It’s, ahh , it’s clean there!”
“How do you know?”
Katsuki freezes for a moment before retorting.
“All those used tissues are clean, you dickhead!”
“Haha, I’m just messing with you.” Deku pokes out his tongue, probably with the intention to be coy, but all it does it make him look like a goofy idiot.
Katsuki however finds it hard to complain, or tell him to stop, or do anything that’s not lay there and lose himself in the exciting sensation of his ass and dick getting rubbed and caressed through scentful wipes. He’s so erect that Deku has to move his hand up and down to clean it, and he does so very slowly, keeping the blood rushing to his crotch without making it too overwhelming. It feels like… It feels like…
A few drops of piss leak down from his upwards-pointing tip and soak the wet wipe.
“Aww, Little Kacchan made a mess? Is this what happened in your diaper?” Deku coos, replacing the wipe with a new one.
“Hmph.” He grumbles, flushing deeply but essentially having nothing to say.
It’s almost concerning, how doesn’t hate being talked like a baby as much as he should. It’s degrading, but also… it makes him feel safe, and cared for. He doesn’t have to prove anything, and nobody gets mad at him for being loud or rude…
Thinking about it, those last few days in bed were the most relaxing experience he’s had in a while.
“Pwetty boy. Baby angel. Don’t worry about it, you’ll wear your big boy pants in no time. Now be good and let me clean your tush,” Deku hums and kisses his tummy.
“Shutup. You’re the sick fuck that gets turned on by babies.”
Deku shakes his head. “I’m not into babies. I just… like it when you need me.”
He gets a new cream, something that feels like vaseline, and rubs it over Katsuki’s sensitive hole. Katsuki doesn’t really know the purpose of it, but it makes everything so smooth, heating his cool skin and allowing Deku’s fingers to move in a fluid manner over the ring of muscles as he lovingly massages it, stretching it and caressing over the wrinkles of his puckered hole.
“I’ve always wanted to support you and be by your side Kacchan, but you’ve never let me. You’ve always been so independent and I admired you for it, but now… when I take care of you, I feel like I’m useful to you, like I’m needed.”
He pushes his finger deeper in, completely burying it to the hilt. Katsuki yelps when he feels it wiggling inside him, testing and rubbing his virgin inner walls. It feels weird, but not bad; the light friction from both sides, his dick and ass, fuels a new fire in him, a dangerous and addictive one he’s never felt before. Katsuki is only starting to enjoy it when Deku promptly slides another finger in, adding to that tight sensation of stretch and starts plunging in, dipping them and out in a sinful rhythm of pulls and pushes.
“I know you have so many people by your side now, but it’s not the same. You don’t need them like that, you only need me . I give you things, special things that nobody else can.”
“I don’t need you, I don’t need anyone—Ahh!”
Katsuki puts his good hand over his mouth, trying to smother his embarrassing moans.
Deku caresses his cheek and moves his hand, making it so Katsuki’s thumb breaches past his lips and he closes his mouth around it, sucking on it to block the lewd sounds.
It’s such a calming sensation, having something fill his mouth as he’s being penetrated. He’s never sucked on his thumb before, but he finds himself enjoying the way it keeps his mouth occupied, resting between his tongue and palate. He bobs his head on his thumb for a bit, trapping in all his moans and cries as Deku deepens his thrusts and hurries his pace.
A third finger is added without a warning, and Katsuki mewls as the pleasant stretching he’s gotten used to suddenly hurts him.
“It—It’s too much! You said you wouldn’t touch me like that anymore!” Katsuki cries out, popping his thumb back into his mouth and biting it.
“Shhh, you’re okay, you’re perfect like this. Just let me do one more thing for you,” Deku pants, his voice coming out desperate and raspy. He changes the angle of his finger, and curves them so they press firmly against a different spot.
Instantly, Katsuki feels pleasure shooting directly from that gland and spreading throughout his entire body.
“Fuuhh!! Mnnhh!!” he moans inside his mouth, molten joy overcoming any other sensation on his body. Suddenly it doesn’t hurt anymore. Suddenly, it’s perfect.
But then, it’s gone. Deku keeps experimenting with his fingers, rotating them, brushing them along his tender inner walls but missing that sensitive bundle of nerves each time. Katsuki even tries to spread his legs further, pressing his pelvis down on the masters so Deku hits that sweet spot, but to no avail—Deku’s thrusting his fingers faster and it feels good, but not like it did before, and Katsuki finds himself whining in frustration.
“What do you need, baby?”
Katsuki can’t say it, no way. He points at his behinds and pats his ass, gesturing to the best of his ability.
Deku spanks where his hand had just been, making ripples of pain and pleasure spread from where his hand smacked. “Does baby need to be punished?”
The pace of the fingers in his ass slows down as Deku thumbles with his pants, and eventually Katsuki realizes why; his shorts are slightly pulled down, and from the elastic band, his huge, fully erect, angry looking cock pokes out.
“No. Nonono. Not this, too big,” Katsuki mumbles though the thumb in his mouth. Deku even trimmed his wild green bush and Katuki regrets ever mentioning something about it, because it makes his cock look even bigger.
Deku smears it in that same glossy fluid and starts stroking himself, looking at Katsuki like he’s going to devour him. “Will you let me Kacchan? Let me make you feel good?”
Katsuki doesn’t have time to consider before Deku breaches in, and the crown of his cock spreads his clenching ring even wider than his three fingers had.
“Fuck!!!”
His breathless pants and gasps force him to yank the thumb out of his mouth so he can breathe, trying to get a grip as Deku feeds his cock into his hole until his balls slap against his flushed cheeks.
He never wanted this. He’s barely been able to process the sexual thoughts invoked by Deku, and now he’s getting fucked by his perverted classmate-slash-nurse?
It doesn’t feel good. It’s so tight he can feel the pulse in his asshole, and tears start collecting in the corner of his eyes.
“Get off of me, you sick fuck!!”
Deku holds his gaze with his intense, stubborn green eyes, not at all offended. “Shhhhh, shh it’s okay baby, it’s just a little boo boo, you’re going to love it,” He says in a calming tone as he starts moving, impaling Katsuki on his huge cock.
“I won’t break you, I’ll be gentle, I promise.”
Katsuki holds on to him with his good arm as he tries to take deep breaths and unclench his muscles. in all sorts of ways, he’s already broken.
Encouraged by Katsuki’s touch, Deku climbs on top of him. Katsuki hopes the changing table is sturdy enough to hold both of them, but right now his mind is too occupied to worry about it—all he can focus on is the scorching hot sensation of Deku’s cock inside of him, the pressure and friction he’s feeling, and how it all feels better the more Deku moves…
It’s so thick that Katusuki can feel it dragging against his sensitive gland, lighting his body on fire again, and suddenly it’s not enough.
Deku’s thrusts become even more animalistic and harsh, and each thrust hits just right, spreading warm waves of pleasure throughout Katsuki’s body. He’s gasps for air as he’s fucked harshly into the matress, feeling his thighs shaking; the injured one trembling like jelly, the healthy one jerking uncontrollably, like he’s simultaneously trying to get away and pull him ever closer.
A hot steam of piss splashes on his abs, pulling him out of that vortex of pleasure. He tries to wiggle out of Deku’s hold but he weighs too much, and drops of urine hit his chin.
“De—ku stop, ahh , this is gross, I cah—an’t stop peeing!” He demands in hysterics, choking on his own moans.
“It’s not gross Kacchan, I actually think it’s really hot,” Deku insists, wiping the sweat off his brow as he thrusts forward with enough force to rattle the entire changing table, looking at Katsuki wit adoration.
It doesn’t change his mind, but Katsuki unconsciously relaxes at those words. He’s getting wet all over, but it’s not like it feels bad—it’s humiliating and he feels like he has no control over his body, but his dick feels just as good, pulsing and spraying as Deku pounds into him, and he feels himself slowly getting lost in pleasure again.
“I love seeing you like this, losing control and pissing yourself for me, letting me hold you when you’re most vulnerable,” Deku slurs without really verbalizing anything specific, just mumbling and expressing himself. “I’m sorry, I’m really sorry but I can’t can’t stop, I know I’m a pervert I’m sorry I just can’t help it, I’m so close and you feel so good, soaking wet and sexy, don’t cry shhh it’s okay, don’t think about anything, just hold me tight, it’s okay,”
Katsuki has never seen Deku like this, but he’s pretty sure that this is what he was like, under the surface, for the entire week . A deep shudder wrecks his entire body and he holds Deku tighter, wetting the both. Deku lets out a feral growl. He realizes he wants this—he wants Deku to turn into the monster he was so scared of.
“More,” He demands needily, pulling Deku by the neck and angles his head so their lips connect.
“Kah- kahhm,” Deku calls his name into his mouth, and immediately opens it wide and slips his tongue in.
It feels like an electric current running in Katsuki’s entire body, conducted by the sweat and piss soaking his skin. Deku’s kiss is animalistic and starved, exploring every corner of Katsuki’s mouth with ravenous passion, sucking on his tongue, smearing spit and biting his lips raw, and Katsuki wouldn’t have it any other way. He feels like he’s delirious with pleasure, each thrusts hitting him just right and spreading waves of heat magnified by the tightness, and the tension in his dick constantly dissolves and sprays out of him, a fountain of tropical waters, warm and salty.
The stream of piss stops just as Deku reaches his peak—there’s a harsh thrust that Katsuki feels in his guts and Deku just stays there deep inside him, his hips sputtering as his dick pulses and spits loads inside Katsuki’s most intimate regions.
He mewls at the sensation of being so full , just a vessel for Deku to use and fuck and suck, and somehow it feels unexplainably amazing, drawing all that power outta Deku.
“Kacchan, pretty,” Deku detaches from him to look down on him lovingly, and starts fucking him again with feirce determination. Every thrust is directly angled at his prostate and Deku hammers it mercilessly, causing Katsuki to lose it completely.
“De—deku-uh! gonna—”
The raw nerves of his insides flex and tighten as his orgasm takes over, stealing his breath like a hard punch. It’s the most euphoric sensation he’s ever felt, serene and mindbreaking at the same time.
Deku collapses on top of him and they both pant hard, catching their breaths.
“You kissed me,” Deku beams , looking at Katsuki like he hung the stars.
“I—fuck, you’re something else when you, you know…” Katsuki blushes like an idiot, unable to utter the word. “Don’t expect me to be all lovey dovey with you, ‘s not gonna happen again.”
Deku chuckles. “I’ll take it.”
Katsuki tries to roll his eyes, but his eyelids feel unbearably heavy, and he goes limp on the changing table, exhaustion taking over him.
He is woken up by his phone buzzing loudly.
“Fuck, it’s too early,” he slurs when he realizes that the sun us barely up as he looks out the window from his bed. He doesn’t remember being put there, or being showered, and the thought that Deku did all that without him being conscious is both heart warming and extremely disturbing at the same time. He fights the urge to check for cum in his ass and answers the phone.
“Took you long enough” Aizawa’s dead-tones.
“‘Was sleeping,” he mumbles, raising a brow at Deku who’s woken up too.
“Reasonable, you’re supposed to rest. Recovery Girl will be here in an hour, so get Deku to return all the equipment and come see her.”
As Aizawa hangs up, Katsuki watches a plethora of emotions cross Deku’s face. He stands up slowly, stretches and looks around the room.
“I guess I’ll start packing the equipment?”
“Clean it up too. I don’t want to return anything with my body fluids,” Katsuki grumbles, still processing the sudden news he’s been hoping to hear all week.
The old bitch is finally back.
He struggles to come to terms with the realization, suddenly feeling stupid for feeling like it’s never going to happen. Or hoping it won’t?
“All right then,” Deku gives him a melancholic smile. “I’ll make sure everything is nice and clean. We still have like, five packs of wet wipes.”
An hour later, Katsuki finally gets that wrinkly, old-people-smelling kiss. He exhales sharply as his numb limbs suddenly start to tingle, tighten at the sudden change, then go limp, free of the organic silicone that fixed his bones and torn muscles in place.
Deku is uncharastically quiet the whole time, simply nodding and smiling shyly at Katsuki when he rolls his shoulder and rotates his elbow.
Recovery Girl doesn’t even look at his renewed movements as she writes and signs a note for him. “You have a bit of time before school, use it to stretch and get used to walking again. I don’t want you in any combat classes today, but tomorrow should be okay.”
“I do what I want,” Katsuki snaps, then recoils when he meets Deku’s stern gaze.
“Fine. Sorry,” he grumbles, looking down at his legs.
The walk back to his room is slow and dreamlike. Deku is helping him walk because his leg is shaky and doesn’t hold his weight well yet, but no one is there to see it so it’s fine—it’s still way too early and the gentle sunshine filters through the big windows, barely illuminating long hallway and making it surreal, dim and familiar at the same time, like they’re in their own little private world.
Katsuki tries to focus on the fact that he’ll finally be free of that humiliating diaper, but finds himself constantly side-eyeing Deku, opening and closing his mouth, unable to form words to summarize this experience.
Like many things, Deku does it for him.
“Kacchan,” Deku finally says as they stand in front of Katsuki’s room again, “I just wanted to say… I know you didn’t like this, but this week we spent together—it meant a lot to me, to be this close to you and being able to help you… really makes me feel like a hero,” he smiles sheepishly, aware of his own cheeseness.
“Not all of it was bad, Nerd” Katsuki chokes out, unable to create eye contact as he unlocks the door. Even after all of it, after everything they did, he’s still shit at communicating…
But it’s fine that way, if he’s with Deku, the one person he doesn’t need to change himself for. Deku understands him and accepts him the way he is, and no matter all his fucked up bullshit, being around him is like returning home . Be it broken and unhealthy, it’s still his home.
Deku wordlessly enters the room with him, fishing a shopping bag from under Katsuki’s bed, and gives it to him.
“I got you a little something, to remember our time together.”
Katsuki takes the bag. Inside it is a pastel green bunny plush, with silky faux fur and lopy ears.
“I know you hate the so-called ‘baby stuff’, but I still wanted to give you this,” Deku explains, rubbing the back of his neck when he sees Katsuki visibly blushing.
“Just to—to remind you to take care of yourself, and that a little softness is good for you too.”
Katsuki scoffs. "Softness?! You’ve been demanding and assertive, taking what you want without even asking.”
Deku doesn’t deny it, and simply mutters “I wonder who I learned it from?”
“Listen, you little—”
“—You can blow it up if you want! You don’t have to take it!”
Katsuki relaxes at his lack of persistence. He takes the bunny plush and examines it, petting the smooth fur.
One of bunny’s beady eyes reflects the light differently than the other, and he presses his thumb firmly into the back of it’s head, feeling a little box behind where the eye is and confirming his suspicion—Deku has just gifted him a stuffed animal with a hidden camera .
He brings the bunny to his face and hugs its belly, groaning into it and hiding his burning face.
Fuck, fuck no. He should burn it on the spot. He should get Deku arrested. He should…
“Whatever. Just leave already, I need to start stretching,” he spits out and places it on his desk, so that the bunny faces the bed.
