Notes read the tags, please, and enjoy ^_^ “Kac-”   “What.” Bakugou snaps, not bothering to lift his head. He’s almost done with vacuuming this end of the hallway and he doesn’t want to be bothered with another annoying question from Deku. It’s bad enough he’s missing out on classes, but he has to do so stuck with that stupid nerd, cleaning the entire dormitory.   “I was just…” Deku continues, “... going to say it seems silly to be ordered to clean this place so thoroughly when it’s, you know, brand new.”   Bakugou clenches his jaw. “That’s the point, idiot. So it stays looking new.”   “I know that.” Deku says defensively, voice lowering. “Still feels like we’re hardly making a difference, that’s all I was saying.” Bakugou sighs, hands tightening around the the handle of the vacuum. “Save your breath.”   He feels… lighter, somehow, since their fight a couple days ago, but there’s something missing. Bakugou doesn’t open up to people like that; he doesn’t cry in front of others and he doesn’t bare his deepest fears and insecurities. He grinds and stomps them back down inside where they belong and he doesn’t think about them anymore. Or, that’s what he’s always believed.   For whatever reason - a reason he’s never been able to decipher - the rules are always different with Deku.   Ever since that night there’s been an unspoken tension hovering in the hair between them. Something splintered that night, that fight was a catalyst for something - he can feel it - but whatever it is, it’s left only rubble and a naked foundation in its wake. Nothing has been built yet, and the new emptiness that exists between them is foreign to Bakugou.   He’s not used to feeling like this around Deku. It irritates him, makes him itch under his skin to do something to bring back some familiarity, all the while knowing that won’t happen.   He’s different now. Deku is different now.   He likes it. He also kinda hates it. He feels like he’s floundering and there’s no lifeline in sight, having to learn how to swim all over again.   Fuck this , he thinks, turning the vacuum off. The gentle hum of the machine dies down and he sets it to rest against the wall, taking a deep breath. They’ve been cleaning nonstop for over an hour and he wants a break, at the very least to get some space from Deku who he can’t help but feel his presence at his back even when he’s quiet. Having Deku at his back should feel normal, it’s how it’s always been before UA, but now it’s just… different.   He turns and walks past Deku to go to the kitchen, suppressing a shiver when their arms almost brush against each other. Deku almost trips over himself to step out of the way in time.   “Kacchan, are you…?”   “I’m just gonna get something to drink, relax.” He says, and once again doesn’t bother to look at Deku as he addresses him.   He goes to the kitchen and fills a glass with tap water, drinking it down without pausing. He washes his hands to get the feel of dust off of them, then scrolls through his phone in boredom for something to do, frowning. Fuck, he doesn’t even have anything to do for a break, except sit alone with his thoughts, and that’s the last thing he wants right now. He’s had enough of that when he’s alone in his room at night, with nothing to distract him.   Even though he has to spend this punishment in the presence of Deku, he at least has something to do with his hands.   He returns to where he’d left the vacuum and Deku, who’s still there cleaning the windows . He’s leaving streak marks all over with the way he’s wiping them, his back visibly tensing when Bakugou draws near as though he senses him entering his space.   Bakugou clicks his tongue against the back of his teeth. “Slow down, nerd, or you’ll just have to redo everything cuz it’s too sloppy.”   Deku’s hand freezes over the window, head tilting to glance at the rest of the window he’s presumably just wiped. “Ah, you’re right.”   “Do it over right now.” Bakugou grinds between clenched teeth, stopping in his tracks to glare at him. He has no idea what has him on edge so much, he’s just, it’s just - ugh, being around that fucking nerd so much is driving him up the wall or something.   “Why are you like this…” Deku mumbles, but he does as he’s told. He crawls back over to the other end of the window, ass poking out as he does so, and starts cleaning again. On his hands and knees like that, he reminds Bakugou of a dog, and he feels his mouth start to stretch into a grin at the thought.   A couple years ago, he probably could have convinced Deku to crawl around for him and bark. Now that he has a quirk, though, he’s grown a spine. It’s not exactly a bad look on him, this newfound confidence, but Bakugou misses it when he knew where everyone’s place was. Now Deku is catching up and he just wants him to slow the fuck down so he can wrap his head around this fact. He doesn’t realize he’s been staring at Deku’s backside for what must have been several minutes until Deku turns around to look at him. “Does this look better?” He asks innocently, and Bakugou blinks to clear his thoughts. Right, the glass.   “Yeah, I guess.” He mutters.   “Are you gonna get back to cleaning now or keep staring at me?” Deku asks.   It’s said completely without malice. Deku’s just an idiot who doesn’t know how to speak right, mumbling and tripping over his words like the loser nerd he is. Bakugou knows - now, at least, since they’ve had their fight - that Deku doesn’t look down on him.   But that doesn’t stop the instinctive white hot flash of anger from burning up inside him. He’s not going to do anything stupid, he tells himself as he stomps forward to wrap a fist in Deku’s shirt collar. Bakugou’s just going to scare him a little. Try to get back a little of that old familiarity, when Deku trembled under his look, even if it’s futile.   Deku sputters, “Ka-cchan!?” as he’s hauled to his feet, and Bakugou takes both his wrists and slams them against the window pane, pinning him both bodily and with his eyes.   “You got something to say to me, nerd?” He spits, glaring.   Deku glares back, but Bakugou can see his pulse pounding in his throat. “What’s your problem, Kacchan? I thought we were past this!”   He’s right; the fire in Bakugou’s gut died almost as quickly as it ignited, now replaced with a low simmer. He’s close enough he can smell Deku’s breath - it’s sweet, and without his permission he finds his eyes glancing down to his plump, teeth-bitten lips.   What the fuck.   He’s got him pinned against the glass, can see how Deku grits his teeth when his back digs into the window grille, eyes flaring with defiance. Bakugou’s heart hammers in his chest, the urge to punch him, touch him or whatever so strong he’s tempted to fight him again, consequences be damned. But he can’t. He’s just rational enough that keeping Deku’s wrists pinned on either side of his head is all he does, waiting to see what he’ll do.   “Let me go.” Deku warns icily, scowling back with just as much force as Bakugou is sure he’s sending his way. His stare wavers a little, evidence that while he may have gained some confidence since middle school, he’s still not fully comfortable in this new confidence. He’s like a little kid trying to wear his dad’s shirt. It’s almost adorable.   Goosebumps pebble across Bakugou’s arms, startled by his own thoughts. Like a switch being flicked and the lights flooding a once pitch-black room, he’s suddenly hyper aware of their positions and the other, possible way it can be interpreted. Pinning Deku against the wall by the wrists, face leaned in to where their breaths mingle, coming out in sharp pants from building anticipation and adrenaline, the way Deku looked bent over-   Fuck, fuck! Bakugou shakes his head minutely, physically trying to dispel the invading thoughts. Where had they come from? Has he really been harboring such deep-seated feelings towards him all this time, or is this a result of his new impressive physique?   Deku seems to take his head shake for something else, and Bakugou remembers that he’d been asked to let him go, but before he can correct himself he feels Deku twisting in his grip, eyes glancing over his shoulder.The air between them is charged, and he doesn’t know what to do? Are they going to fight again? Is that what’s about to happen?   “Kacchan-” Deku gasps, brows pinched in concern, his breath shaky. “I need to- you need to get off of me.”   “Shut up.” He says without thinking. He can’t think. Deku could just throw him off if he really wanted to, anyway, and that knowledge thrills him.   Deku wiggles some more. “I’m not fighting you again, we’re still on house arrest-”   “I’m not gonna fight you, you dumbass. I’m…” but he doesn’t finish, isn’t sure how to finish. Either way, Deku seems completely distracted by something over Bakugou’s shoulder, which is just pissing him off even more, that he doesn’t even see Bakugou as a big enough threat anymore to have his full attention.   Irritated, Bakugou glances over his shoulder but sees nothing. He whips his head back.   “What the hell do you keep looking at?”   Deku flushes deep. “I have to pee, Kacchan, please let me go.”   Something about how pathetic Deku looks in that very moment, averting his gaze like he’s ashamed about having to take a piss, shifting on his feet and desperately glancing back towards the doors to the bathroom, both amuses and annoys Bakugou all at once.   “Oh, you have to pee?” He mocks, mouth stretching into a sneer. “Just piss yourself then.”   He says it dismissively, not serious at all, fully intending to let go of Deku’s wrists the next moment so he can go relieve himself. He’s been cruel to Deku before, but never to such an extent he’d force him to piss his pants. He’s not into that sort of thing, anyway.   But it happens immediately. As if taking the off-hand remark seriously, Deku groans - loud and low - head tilting back to hit the glass. It makes Bakugou freeze, his pupils blown wide. He’s never heard Deku make a sound like that before and it leaves his head spinning, and then to add to the confusion he feels heat radiating below. His wide eyes slowly drag down the length of Deku’s body to rest at his crotch, where a dark patch is rapidly forming at the front of his shorts, spreading out and down the insides of his thighs. It dribbles down his bare legs, puddling at his feet, soaking his house shoes.   Another whimper draws Bakugou’s gaze back up: Deku has his cheek pressed to the glass, round freckled face scarlet, tears budding in the corner of his eyes. But that’s not the part that gives Bakugou pause; he’s panting, chest heaving with what looks like the force of holding back moans. A few little noises escape, and he looks mortified - glancing between Bakugou and down at his own crotch, head tipping forward and eyelids falling half-way shut. His bottom lip is shiny with spit, and when it looks like the last of the piss has left his bladder, he tips his head back and briefly shuts his eyes, humming quietly.   “What the fuck-” Bakugou stares at the piss puddle, utterly at a loss. “What the shit, Deku? Did you really just-?” He tightens his grip on the nerd’s wrists, taking a step away so his feet don’t touch the wet spot, disgusted - he thinks.   The words revive Deku, and his mouth falls open uselessly, words failing to spill out, as he looks frantically between Bakugou and his own soaked shorts.   “Goddamn, you’re a mess.” Bakugou sneers, glancing down once more, and for what feels like the tenth time that morning he freezes, brain shorting out at the sight that greets him.   Now that the front of his shorts are drenched, there’s a perfect outline of Deku’s cock, prominent and hard. Fucking hard, Deku has an erection, what the everloving fuck?   The damp material clings to its shape as it’s restrained in its wet confines, but still managing to curve up, like the strength of his arousal can’t be stopped. It’s almost tantalizing, Bakugou can’t rip his eyes away, and he hears his own breaths falling harsher.   Deku was turned on by that.   By pissing himself, or being held down by Bakugou, or both, who fucking knows. All Bakugou knows, or rather suspects, is that he’s the main cause behind this.   “Please let me go now.” Deku whispers, and his tone sends a spark straight down Bakugou’s spine. When was the last time Deku looked at him like that, sounded like that when they spoke? Before UA, if he can remember correctly, but he doesn’t trust anything right now. He feels like he’s being tipped upside down right now, and all he knows is that he doesn’t mind this one bit.   Bakugou doesn’t mind the way Deku looks at him like he’s both humiliated and aroused at the same time, he doesn’t mind the way he feels stronger than he has in a long time, able to make his childhood friend piss himself just by telling him to. He doesn’t mind the way Deku refuses to shove him off, despite them both knowing he’s more than capable. He doesn’t mind how heady it feels to think about All Might’s successor debasing himself at his command, and getting off on it to boot.   He doesn’t even really mind the faint smell of pee in the air.   “Holy fuck,” Bakugou breathes, “You loved that. You fucking enjoyed that.”   His eyes flicker all around Deku’s face, searching for some sign that he’s reading the entire situation wrong, but finding none. Deku winces, averting his eyes at first, but when Bakugou stares him down, tilting his head to force the other to meet his eyes, Deku relents.   “Yeah.” He says quietly, face contorted as if expecting a barrage of insults to come hurling from Bakugou’s mouth. It wouldn’t be totally unwarranted or out- of-character for him, he supposes. That’s how things surely would have played out between the old Deku and Kacchan.   But Deku’s different now, and Bakugou’s changing as well. This is definitely a change for him.   “You made such a fucking mess. After I cleaned the floors too.” He frowns. He doesn’t really care about the mess right now, his mind is entirely elsewhere. But he also isn’t sure how to get from Point A to Point B. He glances over his shoulder to where the bathrooms are, and finally lets go of Deku’s wrists.   “Come on. You need to get out of those wet clothes.”   When he turns and heads to the showers, he doesn’t look back to see if Deku follows. He walks in and stops, leaning against the wall until the door swings open a couple moments later, Deku looking startled to see him waiting with arms crossed. His cock is still hard and he still reeks of piss, and Bakugou can’t drag his eyes away.   “Strip.” He says, and he expects some resistance, so when Deku blanches he’s already got a carefully planned excuse. “What, are you gonna track your piss throughout the entire dorm? You need to wash off and change your clothes.”   “What- why do you need to be in here?” Deku blinks owlishly at him.   “I’m going to take your wet clothes to the laundry room for you and bring you fresh ones, idiot.” He answers, tapping the side of his head once like it’s so obvious. He can’t tell him it’s because he wants to get an eyeful of what Deku has under those clothes.   “O-oh…” Deku looks surprised. “Thanks, Kacchan.”   Then Deku starts to undress. Pulls his shirt off over his head and hangs it over one of the shower stalls, but wavers when his hands reach his shorts. Bakugou hasn’t taken his eyes off of him the whole time, and it’s apparent Deku has noticed this.   “Um... Can you look away?” He asks, and Bakugou snorts.   “You didn’t seem to mind me staring before.” Bakugou says in a husky voice, and then, as obviously as he can, drags his eyes down Deku’s toned chest to land on his crotch. He hears Deku sputter, hands coming down to shield his groin from view.   “Ka-Kacchan??”   “You were moaning like a slut earlier, now you’re gonna play bashful?” Uncrossing his arms, Bakugou stalks forward and watches with amusement as Deku steps back until he’s pressed against the outside of the shower stall. Bakugou’s never done anything like this before; it’s possible he’s read the entire situation wrong. But he’s never, ever seen someone act like that from pissing themselves, no matter how much of a relief it is to finally not be full.   “Did it feel good to let go like that?” He asks when he’s stepped into Deku’s space, his voice rumbling against the tile walls. “You piss yourself often, or was it just cuz I told you to?”   Bakugou watches Deku’s throat bob up and down as he swallows thickly, and because he’s watching so closely he doesn’t miss the way his eyes track down to Bakugou’s lips briefly before flitting back up.   “I…”   “You don’t have to answer that, I already know.”   And planting his hands on either side of Deku’s head, he brings his mouth down to crash hard into his.   This is what was missing, Bakugou thinks in some distant part of his brain. Deku’s quick to touch him, his hands coming up to rest on Bakugou’s chest, stroking down over his shirt. Embers lick all over Bakugou’s skin and he’s suddenly too hot all over. He pulls back long enough to pull his tank top off and as soon as the material is on the floor he’s being pulled back by scarred hands until their faces are pressed together again.   Their fight outside the dorms before hadn’t felt finished. A tension had lingered between them, a flicker of something thick and heated that was unaddressable. They had come to a new understanding of each other, but the view was incomplete.   Now, it felt whole.   “You want me, Deku.” He mumbles against his lips. It’s not a question, he just wants to hear him say it.   Deku nods frantically as his lips slot against Bakugou’s, their tongues sliding out hot and wet to pet each other before Deku is pulling away with a gasp.   “ Kacchan ,” He whines, voice breaking, his palms pulling incessantly on the back of Bakugou’s neck to bring his lips back. Bakugou pulls away.   “Say it.”   “I want-” Breathes deep, mouth surging forward. “I want you.”   Bakugou kisses him again. “You want my cock?”   Deku flushes deep, biting his lip. “Kacchan…”   “Take off your pants, Deku.” He growls, and steps away from the other’s body heat to watch. Fuck, he wants to see Deku’s thick cock, he wants to see how desperate this little freak is for him. He can’t be the only one whose head is buzzing, who feels hypersensitive all over.   Deku obeys this time, and though it appears his dick has softened a little (no doubt a result of the cold, damp material clinging to it), he doesn’t hesitate when he strips his shorts and underwear clean off, tossing them to the side to land on the tile floor with a wet plop. His cock twitches under Bakugou’s stare, swelling and filling out before his eyes, the foreskin gradually pulling back as it lengthens to reveal his pink tip, slick with precum.   Eventually though, Bakugou pulls his eyes away. “Get in the shower.” He says, and kicks off his own pants, setting it and his tank top far away from Deku’s soiled clothes. When he steps into the shower stall, Deku’s already got the spray started, one hand on the knob and the other palm-up under the water to test the temperature. Bakugou takes the opportunity to soak up all the details.   He’s seen Deku naked, of course. They grew up together and they have to get changed in the locker room together for training, but he’s never felt it was appropriate to look then, and when they were kids Deku was never… he never looked like this.   Deku’s really bulked up. He’s still mostly lean, but he’s put on muscle all over, his ass now firm and round, and freckles are scattered all over his thick shoulders. When he steps under the spray, his curly locks flatten, and Bakugou is mesmerized with the way the water droplets make trails down his back, over his ass.   He steps forward to join Deku under the water, his cock nudging into Deku’s lower back. Fuck, he must have gotten hard when he was watching him and not even realized, but Deku looks pleased as hell when he spins around and gasps, eyes falling to his crotch.   “Can I touch you?” He asks, barely audible over the running water.   Bakugou sneers. “You fucking better.”   Deku scrambles to get both hands on him, pulling a sharp grunt from between Bakugou’s clenched teeth. He’s on fire , the water’s too hot, his cock is aching, throbbing, burning as Deku strokes and palms at him clumsily. It’s cute, the way his brows are furrowed, his gaze on Bakugou’s package intense like he’s studying it. It’s cute, but it’s not enough, and Bakugou drops a heavy hand on Deku’s shoulder, urging him down.   “On your knees.” He rasps, and his cocky grin returns when the mop of green curls sinks to the floor immediately. Without even being asked, Deku takes it with a hand at the base and starts to slobber all over his cock, licking and sucking on the tip furiously, almost like he’s terrified it’ll be ripped away from him in the next second.   “Shit,” Bakugou puffs, the swear turning into a breathy moan, “ Hahhh, ahhh.” He winds his fingers into Deku’s curls, tugging his head harshly back and forth, watching through lust-clouded eyes as his dick disappears inside that tight, wet heat and reappears again, over and over.   “You like the taste of my cock, Deku?”   He nods. A shudder ripples through Bakugou.   “You looked so fucking pathetic wetting yourself like a little kid.”   Deku moans around his cock, causing delicious vibrations to course through his shaft. “Fuck you’re too good at this, you been holdin’ out on me?” He tugs on Deku’s hair harder, until his lips are flush with Bakugou’s pale pubes, until he’s rocking back and gagging, sucking in air hard through his nostrils, spit leaking from the corners of his red lips.   Fuck, it’s too hot. Deku looks too good like this.   “You let anyone do this to you, huh, you slut?” Bakugou taunts, pulling on his hair again. Deku resists, sliding off his cock long enough to answer.   “Only for you, Kacchan.” He says, his big round eyes taking on a sultry twinkle, before he swallows Bakugou back down, lips a tight hot circle around his length. The declaration makes Bakugou feel light-headed, his chest swelling with pride, and he feels his balls draw up tight. He’s close.   Deku hollows his cheeks as he bobs, his face taking on an intense look of concentration, one hand wrapped around the base to move in time with his mouth, the other wrapped around Bakugou’s waist. He’s not touching himself, his gaze and attention focused completely on sucking off Bakugou.   Shit, shit, shit, Bakugou thinks, even sucking cock he looks too cute. Even the bruises splotching his skin from their fight do nothing to make him less attractive; if anything, they only fuel the fire raging inside Bakugou, urging him to give him new ones, ones to remember this moment by.   That’s the imagery that tips him over the edge: Deku’s tight ass covered in red marks, his neck littered with hickeys, fingerprints burned in the inside of his thighs from Bakugou fucking him so hard and raw he cries big fat tears. He feels his limbs tense up, he curls over Deku’s hair, groaning loud and uninhibited, holding Deku’s head down as he spurts thick hot cum down his throat. It feels so fucking good - Deku’s tongue wet and sloppy, and his throat constricts around the very tip of Bakugou’s dick as he drinks him all down. By the time the last drops have seeped out, Deku’s tongue poking out to lick them up as the hand working Bakugou’s cock slows to a stop, Bakugou’s legs have turned to jelly.   Deku’s eyes flash up to meet Bakugou’s, his hand still around his twitching cock, and something passes between them. Bakugou’s not sure what, exactly; he’ll figure it out later, when he’s not tingling all over.   The sensation of being touched is all too much then, and he pushes Deku off of him, taking a step back to stand under the water spray again, momentarily losing himself in the calming feeling of the water running down his face and body. Without opening his eyes he can feel Deku’s gaze on him, eating him all up.   He opens his eyes, sees Deku still on his knees and fisting his cock slowly, looking at Bakugou and biting his lip as he does so. Most of the water on his body has dried, but his curly hair still lays limp, dripping at the ends. The droplets trace down his pecs, over the ridges of his abs… and Bakugou gets an idea.   He steps forward, taking his cock in hand. It’s still half-hard, the visual of Deku on his knees and jacking off not doing anything to help him calm down. He doesn’t give him any warning, and it takes him a second to get his junk to cooperate, but once the stream of piss starts he aims it at his chest, satisfied when he hits his mark right between Deku’s flexing tits.   Deku whimpers as soon as it touches him, and he shimmies forward on his knees to get closer, pursing his lips closed tightly and tilting his head back. Bakugou can’t help the raw sound that tumbles out of his mouth.   “ Ahhh, fuck, take it you disgusting slut.” He wags his cock once, and the stream jumps with it, a splash hitting Deku’s chin. “What would All Might think if he saw you like this?”   Deku flushes with shame, but he doesn’t stop the hand on his cock, the piss cascading down his body and over his lap making the movements of his fist squelch loudly.   “ Kacchan ,” He mewls, shoulders slumping, fingers tightening. He comes almost silently, mouth falling open, and leans forward as though trying to get more of the waning flow on him before it ends. Only a single gasp escapes his throat as he jerks his dick harshly, and once Bakugou’s run out of piss Deku leans forward to press his forehead against his hip, a splatter of cum painting his calf.   Well, shit, that was one of the hottest things Bakugou’s ever seen. Maybe he’s more into that kinda thing than he thought. Maybe, similar to what Deku said, it’s only because it’s for him.   Bakugou blinks lethargically; the aftereffects of orgasm must be messing with his head for him to be thinking so mushy. But regardless, he helps Deku stand to his feet, bringing him over so they’re both under the warm water.   Eyes boring into him like he’s trying to dismantle him, Deku tugs on the back of Bakugou’s neck, pulling him down for a chaste kiss. When they part, Bakugou’s throat has gone dry. Lips too loose before, now he feels he has nothing to say that words can convey.   As they finish washing up, taking turns to scrub each other’s backs without even having to ask, he thinks: maybe some things don’t need words.
