Work Text:
Katsuki loves his boyfriend a lot. He really does.
But the sight of Shouto in nothing but an oversized t-shirt – his oversized t-shirt – and a pair of black boxers with the word DYNAMIGHT right on his ass is the number one factor of Bakugou’s fluctuating sexual preferences.
Is it weird that his boyfriend is wearing his hero merch? Not at all, Bakugou would say it’s the highlight of his morning, seeing Shouto in those ridiculous (but insanely hot) boxers.
What makes this all weird is that Shouto does not know, in fact, that he’s wearing Katsuki’s hero merch. Which is equally frustrating as it is arousing.
Getting turned on by the idea of his boyfriend being interested in your hero persona without knowing that Bakugou and Dynamight are the same person awakened some very, riveting to say the least, desires in him.
To keep his identity a secret was partially by choice, but more so influenced by the danger it could potentially put Shouto in if the media or, even worse, villains were to find out that Dynamight is dating a civilian. He’s been thinking of telling Shouto, as this secret identity shit can’t fly with a long term relationship – and Katsuki’s not letting go of his candy cane headed pretty boy boyfriend, not a chance in hell.
They’ve only been dating for half a year now, both busy with college, Shouto with his part time job at his brother’s company and Bakugou with being a hero on top of it all; they get busy, and in the moments they do get for each other, the thought of dropping that information on his boyfriend isn’t always on his mind.
But in moments like this one, when Shouto’s swaying his bony hips while humming to faint music playing from his phone, hair astray from not having combed it yet, the big, bolded letter DYNAMIGHT staring Bakugou down, he’s reminded of how awful it feels to lie to his boyfriend. The added shame of Katsuki tiptoeing on the line between easy banter and flirting with Shouto as Dynamight doesn’t quench the unsettling swirl of emotions in his gut.
It was easier before; when Bakugou still pretended to get annoyed by Shouto; pushed and pulled at him to get a rise out of Shouto and cause the other to snap at him, because they couldn’t get along like two normal human beings back then; teased him about his Dynamight keychain and the posters stuck to his bedroom wall.
He’s taken down a few and replaced them with a multiple photo frame of the two of them – several memories from their past dates and candid snapshots they took of each other – it’s sappy as fuck, but Katsuki feels more proud of Shouto having those photos up on his wall rather than another poster of him as Dynamight.
That’s not to say Shouto’s still not adorably captivating when he comes home with another kitschy Dynamight trinket. The half and half dumbass even bought their cats matching Dynamight and FrostFire collars. “They make a great team, don’t you think?” Shouto poised when he’d shown Katsuki his purchase, color coded with a bell dangling in the middle and all.
Sometimes, all of this parading Shouto does with Dynamight’s merch feels almost like he’s teasing Bakugou. Like he knows about it, about them being one and the same, but decides to keep it to himself until Katsuki ultimately snaps and blasts his face off, along with the godawful (but infuriatingly fitting) underwear.
Or maybe Shouto’s been hanging out too much with Izuku and his hero obsession rubbed off on him too.
The only good coincidence that came out of this is that Shouto’s effectively fanboying over his own boyfriend without him knowing.
Maybe that does make Bakugou an asshole, at least a little bit.
“Hey, Shou! C’mere for a bit.”
Shouto perks up at the call of his name and looks behind his shoulder, hands still working on the breakfast he’s been preparing for the two of them.
His boyfriend has been getting better at cooking, obviously, with Katsuki and Fuyumi’s help, and the more dishes Shouto learns to make by himself, the prouder Bakugou is of him. He’s not only looking forward to try the food, but also to Shouto’s shy little smile that turns earnest when Katsuki compliments his efforts.
After making sure there’s nothing that could potentially be left to burn, Shouto makes his way to the dining table where Katsuki has set their plates and cutlery, cutely tilting his head just so, looking down at him with expecting eyes.
“Yes, Katsuki?”
Fuck him for being so stupidly cute all the damn time. Katsuki might just do that right here on the table, forgetting all about breakfast and the classes they both have to attend today. But he has a strong resolve, and the orange waistband of the Dynamight boxers is snugly fitted around Shouto’s waist, taunting him.
Bakugou loops one arm around his middle and pulls Shouto to sit on his thighs, causing his boyfriend’s hands to grip onto his shoulders for balance. The curious look in his eyes isn’t diminished, but said gaze does flick down to Katsuki’s lips for a brief second, a telling hint of how little they can keep their hands off each other.
His other hand comes round to squeeze a handful of Shouto’s ass, right over the printed orange DYNAMIGHT, and Shouto’s hips buck forward reflexively. Bakugou’s mouth curls into a grin, lids falling heavy over his eyes as he leans forward to kiss the breathy whine off Shouto’s mouth.
The ministration of his hands doesn’t stop there, as his middle finger comes in between the cleft of Shouto’s ass, bunching up the fabric of the boxers over his crotch, teasingly rubbing incessantly close to his hole. Shouto doesn’t question Bakugou’s sudden affectionate assault, only pushes his behind further into the cup of his boyfriend’s grip, eagerly responding to his kisses.
“Fuck, Shou, so fucking pretty for me, princess.”
A sensual lick accompanies Bakugou’s words as they’re breathed over the seam of Shouto’s lips, before they collide together once more, the slide of their mouths a mirror image of Shouto’s hips rubbing on Katsuki’s thigh.
“Ah, Kats-“
Shouto moans, high and needy in his throat, and it’s clear that the pretty boy has no idea the stupid boxers he’s wearing were the sole perpetrator of this morning heavy makeout session. Has no fucking idea that Katsuki goes stupid when he sees him first thing in the morning, wearing Dynamight’s name, his name, on his ass of all places.
"D'you like wearing Dynamight merch around the house, princess?"
"Ah, so that's what this is about."
Shouto pulls away from the kiss, not without wiggling his butt a little in Bakugou's lap. It's hard to hide his groan when the breath of it hits Shouto right in the face, across his spit slickened petal lips, though he tries nonetheless, while shamefully aware of how hard he is right now.
Shouto must feel it too, given the purposeful undulation of his hips, making sure to graze Katsuki's bulge.
"What is what about, sweetheart?"
"This" Shouto gestures to the hand Katsuki's got in his boxers, two fingers already thumbing around the rim of his puckered hole.
"you usually wait until we've had something to eat, or I'm the one interrupting you while you cook."
The words are whispered over his mouth, but his boyfriend doesn't lean in all the way to seal them with a kiss, so Bakugou has to stare dumbly at the pink pout of his lips.
"S'got nothing to do with the stupid underwear, Shou" Bakugou lies through his teeth
"Really? Do you get possessive when you see me wearing another man's clothes?"
Bakugou sputters, brows furrowing together. His hands move to grip tightly on Shouto's waist to try to get a reaction out of him, though Shouto only grin smugly at him.
"These aren't another man's clothes. These are your ludicrous Dynamight boxers."
"Same difference. But really, does it bother you?"
Bakugou stays silent for a beat, searching the appropriate answer for this situation. He can't just spew out that he fucking loves seeing Shouto in Dynamight merch all the time because he feels like Bakugou's put his brand on him.
"I think you like it. That's why you kiss me so aggressively each time I wear Dynamight merchandise." Shouto leans closer to whisper in his ear
"You like reminding me who I belong to."
Icy words wash through him like a glaciar shiver, the confirmation that Shouto belongs to him, falling from his own lips, feels better than any stupid hero rank he's achieved so far.
It doesn't erase the fact that Shouto's a damn pain in his ass, and that Bakugou is lying to him in his face about who he really is. About who's fucking idiotic boxers his boyfriend is wearing.
"I'll do more than just show you-"
"Ah, the food." Shouto cuts him off, tone shifting from breathy and sultryl to monotone and unaffected.
"The fuck-"
"It's getting late, and you have an early class, Katsuki."
Shouto continues, getting up from his seat on Bakugou's lap. What a fucking shame.
"I know you hate being late. I'll pack you a bento."
And there he goes, scurrying the fuck off to the kitchen to finish what Katsuki previously interrupted him from.
Bakugou doesn't miss the alluring length of his pale legs, strong thighs flexing as he walks, faded bite marks still faintly visible on the inside of them. Shouto's pretty little ass clad in tight DYNAMIGHT boxers will haunt him for nights on end, though he can't lie and say it's not the hottest thing he woke up to.
His hair is even more mused up than before, courtesy of Katsuki's greedy fingers, always eager to thread and tug and pet the silky strands of crimson and ivory. The bangs fall in Shouto's face most often than not, making a good excuse for Bakugou to brush it aside and kiss his forehead.
Shouto's shoulders are narrower than his, but still broad, with a boxy waist, but nothing Bakugou can't fully grasp with both hands. All that and the delicious expanse of his skin is hidden away under his t-shirt. Shouto cannot seem to be physically capable of wearing anything that's his own ever since they started dating.
It's, fucking endearing or some shit, and it sometimes makes Bakugou's heart beat so fucking fast it might leap out of his chest. And, they look good on him. Shouto looks good in his clothes.
Shouto looks fucking cute in his boyfriend's clothes.
Yeah.
Fuck, he loves that pretty bastard so much it's incredible he hasn't turned into a pile of mushy goo at this point.
He deflates like a balloon, slumping down on the chair, and the small chub of his dick mocks him as it pokes at the front of his sweats.
"Fucking stupid pretty boy- argh."
Hands rub at his face and he gets up to help Shouto finish cooking, they'll get it done quicker together.
But not without another playful slap to Shouto's ass, which gets him a swat at his shoulder and a peck on his cheek.
It's good. He'll tell Shouto another time.
Ideally before he busts a nut over Shouto wearing stupid hero merchandise.
----------
He doesn't tell Shouto another time.
At least, he doesn't get to tell Shouto before the next time he meets him as Dynamight, which he should have, because this way he wouldn't have to go back to the agency to change, and come back to Shouto's place.
On top of all that, he could have positively swooped Shout off his feet and flirt with him unabashedly even when he just got off duty, dirty suit still on, have Shouto take off his mask so Bakugou can pin him to the balcony railing and smother him in kisses.
"You ought to stop putting yourself in danger, pretty boy. I might not be there next time to save you."
Shouto chuckles lightly as he hops onto his balcony, dusting off the nonexistent dirt on his pants. Always the prim and proper young master. Katsuki is glad for the mask covering his mouth, as he feels a grin settling at the curve of it.
"I don't do it on purpose. But thank you for saving me, Dynamight...again."
He laughs once more at the implication that this is not the first time Dynamight saved his pretty boy ass from a villain, or an incoming crashing building. If FrostFire were there on the scene instead of slacking off god knows where, he could have frozen the building.
Though many times heroes can't focus and put blame on the if's.
“Yeah yeah, save your thanks for someone else. It’s my job to save people, pretty face.”
Shit.
He said he’ll tone it down with the praises when he’s suited up, but the nicknames just roll off his tongue when he’s with Shouto. And the current situation doesn’t help at all; the villains were apprehended and turned over to the police, no one had been gravely injured and Shouto had just hopped out of his arms after Dynamight flew them up to his apartment.
Fucker’s wearing a Dynamight hoodie, which only raises his possessive streak. Shouto must know what he’s doing, Katsuki doesn’t remember seeing these many clothes in his boyfriend’s closet with his hero name on them.
“Then I guess I’ll have to find another hero to save me, hmm…”
Shouto drawls out, purely to rile Dynamight up, and the pretty bastard is well aware of what he’s doing and what effect it has on the hero.
They’ve always seemed to have this easy going banter between them, even before Katsuki swallowed his stupid repressed emotions and asked Shouto out. It might have been due to his suppressed feelings for Shouto and finding safety under the hide of his mask that spurred Dynamight to start flirting aggressively with him, although that all toned down when they became boyfriends.
It still comes up every now and again, when Bakugou doesn’t know when to hold his tongue and bite his cheek, hold back from drowning Shouto in syrupy compliments, as he still has to pretend he’s not said pretty boy’s boyfriend, only hidden behind a jagged edged eye mask and a voice changer.
“You’re throwing me to the side this fast, princess? Thought you were my number one fan.”
A little flirting disguised as playful banter won’t hurt anybody. S’not like he’s asking Shouto to cheat on the boyfriend he might have mentioned once or twice to Dynamight. He was planning on revealing his identity to Shouto anyway, though right now might not be the best timing, what with Dynamight needing to get back to the agency to drop off his reports-
“I am? I’m sure there are other fans who look up to you more than I do, Dynamight.”
Shouto states with a minute tilt of his head, and his fingers grip onto the edge of the hoodie. A clear sign he knows what prompted this.
“You’re definitely the prettiest one, I can fucking guarantee that.”
It punches him right in the gut, the way Shouto’s eyes widen at the easy admission of his beauty, cheeks turning a faded shade of red. He’s always been apprehensive when receiving compliments, still gets shy when Katsuki takes his time to kiss all over his body and whisper how pretty and beautiful and gorgeous he is.
That doesn’t mean it’s not the prettiest sight he’s ever seen.
“I have a boyfriend, Dynamight. He doesn’t like it when other people flirt with me.”
So the pretty bastard knows he’s being flirted with. Fuck, this is all backfiring at Bakugou right now, he should just rip off the mask on his face and let Shouto see his face. Let Shouto see what a dumbass he’s got as a boyfriend.
“Yeah, fuck, I know. Just- stating the obvious.”
Dynamight backtracks, suddenly feeling shitty for coming onto Shouto while his boyfriend is still none the wiser to who’s currently on his balcony.
“It’s still nice to hear it. Even if my boyfriend would probably throw a fit if he were to find out.”
Shouto’s voice pulls him away from where he was spiraling in guilt, a heartfelt smile on his face. As difficult as it used to be for his boyfriend to receive compliments, he’s gotten better at accepting that he’s not ‘unsightly’, as he used to think he was. That his scar and his ridiculous two toned hair doesn’t make him any less beautiful, and despite Katsuki acting like an asshole when others call his boyfriend ‘pretty’, he won’t actually beat up anyone who compliments Shouto.
Shouto deserves to receive love from those around him, not just from his boyfriend. Even if those compliments come from the same boyfriend who’s now pretending to be someone else.
Katsuki doesn’t condemn Shouto if he’s going to be angry when he finds out.
“Actually, he might even enjoy it. He likes showing off that I’m his boyfriend. Katsuki does get possessive sometimes…”
His words turn to a murmured whisper, as if Shouto was talking to himself. And maybe he was, this doesn’t sound like something Dynamight should know about.
Unless he could play this to his advantage…
“Really? Your boyfriend won’t mind if I flirt a little with his pretty boy?”
Shouto looks up at that, blush intensifying at the implication of Dynamight’s words.
“That’s not what-“
“I’m just kidding, princess. M’not that much of an asshole.”
Having resented to probably getting the most brutal silent treatment from Shouto when he reveals his identity, Dynamight trails his eyes slowly over his body, stopping when they catch movement. Shouto’s rubbing his thighs together, fingers gripping tightly onto the hem of the hoodie until his knuckles turn white.
Shit, he’s into this.
“I can tell you enjoy it. I promise I won’t tell your boyfriend.”
Dynamight winks, his grin crinkling the edge of his eyes when Shouto averts his gaze and bites gently at his lip. Katsuki doesn’t know how to feel about seeing his boyfriend effectively getting turned on from having Dynamight flirt with him a little. It’s definitely fucking hot, ‘cause he’s still himself, but Shouto doesn’t know that-
“There’s nothing to tell. Don’t be mean, Dynamight.”
Shouto honest to god whines, his lower lip, now red from having pearly white teeth digging into it, jutting out into a pout.
“Alright, alright. I’ll be good-“ It’s hard not to go on when he sees Shouto sighing in relief “-but just for you, princess.”
The hero flees off the balcony before Shouto can fling a potted plant at his head. It’s happened before, and Dynamight doesn’t feel like testing his reflexes tonight.
Bakugou is uncomfortably hot, bothered and guilty under the safety of his hero suit as he blasts himself to Eraserhead’s agency. And he knows he won’t get rid of the itchiness engulfing him unless he comes clean.
-----------
Shouto is already in bed by the time he gets home.
“I’m home, Shou.”
Home seems to be more and more wherever Shouto is, despite them not living together yet.
“Welcome back, Katsuki.” Shouto beams from where he’s resting against the headboard, blanket thrown over his feet. The cats he saw sleeping in their nest of pillows in the living room, they particularly love the spot next to Shouto’s array of plants.
Their relationship is still in its beginning stages, but with how long they’ve known each other for, to Katsuki, moving in together doesn’t seem like rushing things.
They already have two cats together which live in Shouto’s apartment, bringing the rest of his stuff over shouldn’t be too much of a hassle.
Katsuki walks to Shouto’s bed where his boyfriend is idly scrolling on his phone, the thought of filling the other half of the closet with his own clothes a constant in his mind.
But before he can do that, a more pressing matter has been bugging Bakugou all day.
“How was work?” His boyfriend asks, just like he asks him every day after Katsuki gets off, supposedly, from the internship he had to lie about at his parents’ company.
Fashion isn’t a field he seriously considered getting into, but that seemed like the most plausible job to hide the fact that he’s a whole hero, as it would prevent Shouto from trying to go over to his place of work and surprise him.
“Same shit every day, though the old hag didn’t throw a hissy fit today. It was okay.”
On instinct, Katsuki falls into bed and scoots close until he’s nosing at the warm skin of Shouto’s neck, a flutter of soft kisses landing just below. “Wanted to come home to you.”
A few years ago, he would have gotten embarrassed about claiming such thing, but now, in the safety and comfort of Shouto’s presence, under the cozy warmth of their shared blanket, Katsuki doesn’t give a shit about being sappy with his boyfriend. That’s the shit that comes with them being boyfriends – being sappy as hell until he feels like his gums hurt from the sweetness of it.
“I missed you too, ‘Suki.” Shouto puts his phone away on the nightstand and shifts to the side, lips following the line of sandy hair, brushing chaste kisses all over the expanse of skin.
Gentle hands cup his face and align it upwards, the guide of Shouto’s grip making it easier for their mouths to meet in the middle. It’s a slow kiss; like a ‘welcome back’ hug; like the rays of the setting sun grazing their skin right before it disappears over the horizon; just like how Shouto’s lips feel after a day of being thrown around and having your ears ring from explosions.
His own hands, a little rough from today, but loving nonetheless, find their way under the hem of Shouto’s sleeping shirt and settle on his hips. No further intent is put into his touch, just the crave of feeling his pretty boy’s skin under his fingertips. Skin jumps when Katsuki traces his entire palm over Shouto’s stomach, feeling the fluff of his happy trail tickle the heel of his palm.
Shouto arches his back at that, pushing his front into him, wordlessly asking Katsuki to touch him more. Touch him all over, because his pretty boyfriend loves when he has all of his attention. Loves having his body mapped by Bakugou’s own two hands. Loves when he gets Katsuki to think with his dick only and have the time of his life without lifting a single finger.
Fuck, how he loves Shouto, not even words can describe it. Or rather, Katsuki might have to learn a whole other language to describe it, if he can’t find the fitting words in his own mother tongue.
When a leg comes to rest over his hip, Katsuki’s brows furrow, as this wasn’t the way he wanted to take things tonight. He had a plan, thought of how he was going to tell Shouto about his identity on the way here, told himself he wouldn’t cave in and sink into the welcoming warmth that is Shouto, both figuratively and literally.
“Mm, Shou, wait, I gotta- tell you something, baby.”
Pulling away from his mouth is probably one of the worst and most difficult things Katsuki has to do on a daily basis. Willingly halting his kisses with Shouto feels like a knife lodged in between his ribs, no matter how dramatic he might sound for that. Though, once you’ve kissed Shouto, there’s no coming back from it.
Not like Bakugou was going to let anyone else kiss his boyfriend.
Shouto is his, goddammit, and he intends to keep it that way for a long long time.
(Ideally forever, and beyond that)
His boyfriend does stop and reels back, supporting his body on his elbow. He’s half laying on top of Katsuki, and his hands are around Shouto’s waist. He has to take a second to remind himself how fucking good it feels to just hold Shouto in his arms like this, a little tired from the day, but both clearly more than a little excited to come back to each other at the end of it.
“Wait, can I tell you what happened to me today? Then I promise I’ll listen.”
A chin digs into his sternum as Shouto makes himself comfortable, arms looped around Katsuki’s middle and long legs straddling one of his thighs.
Bakugou thinks he has an idea of what Shouto wants to talk about.
“Course, baby.” He says, choosing the verbal admission over a simple hum. The widening of Shouto’s smile is proof that it was the better approach.
“You know how you got jealous this morning over my Dynamight underwear…”
“Fuck you, I didn’t get jealous. I told you, s’just, weird that you wear boxers with a hero’s name plastered all over your ass.”
Bakugou’s weird translated to weirdly arousing and possessive, although he doesn’t have to say that out loud for Shouto to catch on. Little shit’s been getting freakishly good at reading him.
His boyfriend laughs through his nose, the corners of his eyes crinkling like wax paper tied around a bouquet of roses, and the hold he has around Katsuki’s body tightens, like the habit he has of squeezing his hand whenever they’re in public, a silent ‘I’m here if you need me’ an ‘I love you’ and other times ‘You’re not alone in this’.
Tonight, it’s most likely a ‘I know I’m being a little shit, but bare with me because you love me’, and it causes the expletives on the tip of his tongue to vanish.
“I met Dynamight today.” There it is. “I was being careless again and got involved in a villain attack and he saved me.”
Katsuki attempts to harden his face at that, thinking back to all the times he’s chastised Shouto for wandering into a crime scene or a hazard zone and potentially getting hurt. He doesn’t interrupt him again, but Bakugou does start to rub little circles into his skin, a silent scolding for now. And a reminder that he doesn’t want Shouto to get hurt.
“He brought me home, no matter how many times I’ve told him I’m safe to walk back. Do you think he does that for every civilian he saves? It seems a little inconvenient for him to do so…”
Yeah, it’s a little stupid that he insists to fly Shouto back home each time, but back when they weren’t dating, getting as much time along with him was a strong desire in Katsuki’s heart. Sue him for wanting to make sure his boyfriend makes it home safely.
“Yeah, he must waste a lot of time hauling your ass home.”
It never gets less weird to talk about himself in third person, but over the years, as Bakugou’s kept his identity a secret from all his friends, it turned into an odd sort of regularity.
“FrostFire walked you home once, too. I remember you telling me about it.”
“Didn’t think you’d remember, but yeah, he did. Icyhot wouldn’t get it through his thick head that I didn’t need a fucking bodyguard.”
Katsuki has no idea where Shouto is going with this, but the mention of FrostFire walking him home rekindles an even deeper buried memory of his. He feels so fucking bad for thinking about the time when he, as Dynamight, fucked FrostFire in a dingy alley that one time after patrol, how they’ve been dancing around each other for god knows how long, though it never turned into anything more.
They’re heroes, they can’t get involved in relationships, and for the most part, at least on Bakugou’s side, the attraction between them had been purely physical. A way to decompress after a long shift of heroics.
Not to mention, he’s been head over heels for Shouto at the time, too.
“Dynamight called me pretty today.” Is what tumbles out of Shouto’s mouth next, and Katsuki, to his own mortifying discovery, feels heat pool in his crotch.
“Did he now?”
Thick fingers flex around the jutting of Shouto’s hips, unintentionally pulling him even closer.
“Mhm. Told me I’m his prettiest fan.”
Shouto looks like he’s having the time of his fucking life. Droopy eyelids fluttering like the flaps of a butterfly’s wings, alluring pink tongue coming to wet his lips. Katsuki doesn’t even pretend to hold back, diving in to kiss those maddeningly enticing lips once, twice, the third kiss ending with an inviting lick of his tongue over the seam of Shouto’s mouth.
It looks wetter now, fucking delectable, and Katsuki submits himself to the torture of looking without touching. Though, not for long.
“You are pretty, Shou. The prettiest fucking boy in the world.” He confirms, basking in the darkening of Shouto’s pupils and the high rosy flush on his cheeks.
“I told him you’d get upset about it. About Dynamight flirting with me.”
“You did, sweetheart?” Bakugou repeats the question, if only to see Shouto nod his pretty head, feel the tickle of his hair bouncing along with the movement of his head. “Want me to pick a fight with a hero over you?”
Instead of craning his neck forward, Katsuki raises his knee and topples Shouto into him, causing his boyfriend to slide forth over his body until their mouths press together in a smack of a kiss. Shouto laughs, loud and joyous, can barely keep his mouth shut to kiss properly.
Katsuki likes these kind of kisses the best.
“I could. Don’t need to tell me twice, Shou. You know I’d fight the entire world for you.”
Locking gazes with his boyfriends while he’s this close is hard without crossing his eyes, and Katsuki will take a little awkward fumbling to see the open adoration in Shouto’s eyes.
“I don’t think you want me to do that, though.”
No matter how many times Katsuki reminds Shouto that if he demands something, he’ll get it. Including Katsuki clubbing his bastard of a father over the head. Yet pretty boy doesn’t need any of that shit, said he only wanted Katsuki to love him and be with him.
So Katsuki does just that.
“No, but…”
Suddenly, a veil of shyness obstructs the previous unabashed eagerness.
“But what, princess? You can tell me, Shou.” Bakugou brings his mouth close to Shouto’s ear, tugs at the lobe with his teeth. “I can tell it’s something good, baby. I can feel how much you’re enjoying this.”
He’s playing it up for the most part, but there’s a definite half hard outline in Shouto’s shorts, and with how he’s been pawing at his chest, it’s safe to say his pretty boy is getting hard over having Dynamight praise him.
“I thought you might get upset about it, but the way you reacted this morning…it made me think you might actually like it. You like reminding me, and everyone else, that I belong to you.”
Having Shouto say all this so confidently and sure of himself is getting Katsuki achingly hard in his briefs, no doubt the head of it poking the inside of his boyfriend’s thigh.
“That’s because you are mine, Shou. Right?”
There’s no question about it, but he still asks, cocks one eyebrow at Shouto just to see him melt like a pile of warm liquidy wax under the heat of a flame, slowly nod his head as he leans forward to steal another kiss.
“Only yours, as you are mine, Katsuki.”
Shouto squirms deliciously in his grasp, feeling overly turned on for a conversation like this one. Katsuki would love to think it’s all him doing this, getting Shouto this hot and bothered, but then his boyfriend wouldn’t have brought up what happened like an hour ago.
“But there’s still something…” Shouto tries to get out, the breath of his words falling over Bakugou’s wet lips.
“You liked it, didn’t you?” Katsuki bites the bullet, no matter how much this is messing up his previous plan. Shouto’s too wound up to get him back on track, and clearly enjoyed having Dynamight call him ‘pretty’ more than he’d let on. Enough to hump Katsuki’s thigh as soon as he got home.
“I, yeah. I liked the attention. Does it- does it upset you?”
The innocence on Shouto’s face does not measure with the way his cock is currently drooling and twitching in his overly tight shorts, and Katsuki, just to be a little mean, moves his hands to grope at his ass under the leg holes of the pants. He squeezes once for good measure, relishes in the way fat spills between his fingers, before pushing Shouto’s hips into his thigh, get him to rub himself on his thigh.
“Fuck no, and you wanna know why, Shou? Cause you’re mine. You’re my boyfriend, no one else’s.” His words encourage Shouto to grind down on his thigh, breathy whines rolling off his tongue like the most beautiful melody on the face of the earth.
“And how could I get upset when you’re enjoying it this fucking much, princess?”
Katsuki trails kisses from the corner of Shouto’s mouth, up to his cheek and down to the cut of his jaw, low enough to nibble at the sensitive spot at the high of his neck.
“Did you get hard in front of him? Did Dynamight see how wet you get when he calls you ‘pretty’?”
Shouto looks torn between nodding and shaking his head, poor baby probably didn’t even catch the way his thighs rubbed together like he was begging Dynamight to put it in right there on his balcony.
“I didn’t, Katsuki haah-“ Shouto chokes on his words when he feels fingers dig harder into the plushness of his ass. “You know I would never do something like that…shit with anyone but you, Katsuki.”
It’s so fucking cute, how Shouto’s admitting to Katsuki that he would never cheat on him when he so clearly wants Dynamight to fuck him stupid.
“I know, princess. But you’re really fucking hard, Shou. Told you your celebrity crush on Dynamight is getting out of hand.”
Emphasizing his point, Bakugou moves his hands to get rid of Shouto’s pants, delighted at the sight of his bare lower half. Pretty boy didn’t even bother putting on underwear before he decided to get off on his thigh.
“You want him to fuck you, don’t you, Shouto?”
His boyfriend moans loud at that, like a rapture separating the storm clouds from the white and fluffy ones, and his erection weeps, dribbling all over the fabric of Katsuki’s sweats.
“Shit, you really do, princess. Want Dynamight to fuck your little hole, fill you up just like I do every fucking day?”
Shouto’s rim is pulsing hungrily around the pad of Bakugou’s finger. He doesn’t push further, stick to rubbing it over the puckered hole, no doubt the raw ministration turning maddeningly frustrating in Shouto’s lust muddled mind.
Having never thought he’d get his boyfriend to admit to such thing, the reality of it baffles Katsuki. It confuses his mind, but his dick seems to have gotten the message crystal clear, the bulge of his fat cock brushing over Shouto’s own leg as he squirms in his hold.
“I do. Katsuki, I really do! Want Dynamight to fuck me- want Dynamight to hold me down and make me take it…”
Hungry lips seek each other in the headiness of aroused bodies and panted words, a foreign kind of craving surging through their veins as they come together in a tangle of kisses.
No matter how good and earth shattering it feels to have Shouto grind his pretty cock on his with the sole purpose of getting off, Katsuki really wants to fuck him, and their lube is too fucking far away, stashed into the bottom drawer of the nightstand. He can’t fucking reach it without detangling himself from Shouto.
“Tell you what, Shou.”
His boyfriend lets himself be maneuvered to the side as Katsuki retrieves the bottle of lube and chucks his shirt at the foot of the bed, looking positively drunk on lust and desire.
“I’ll be your Dynamight for tonight, princess. What do you say? You can do whatever you want to me, or I can take over if you’d prefer.”
Shouto’s cock twitches in response, a line of precum dripping down the length of it.
“Lay down on the bed, Katsuki.”
He raises one eyebrow at the call of his name, and it takes a few beats for Shouto to catch onto the new scenario they’ve just opened up.
“D-Dynamight, please, come here.”
Shouto looks more affected now, lips tasting the hero’s name like he’s licking and swirling his tongue over a cone of ice cream. Or maybe Katsuki just feels like melting right now.
“Heh, I normally don’t take orders from a civilian, but since you asked so fucking nice, pretty boy…might as well indulge you tonight.”
A distinct shine in Shouto’s eyes is telling enough that he got exactly what he wanted, Katsuki having played right into his hands. He doesn’t mind it, not one bit, not when his boyfriend looks hungry for his body and parched for his kisses.
The bottle of lube is tossed somewhere in the ruffled sheets as Bakugou lies down on his side of the bed. A line of sweat has gathered in the stroke between his pecs, along with droplets of perspiration trailing down the back of his neck. It’s suddenly really fucking hot in the room, but Katsuki chalks it up to arousal. He’d been too entangled in Shouto to notice how warm he was.
Pretty boy settles back in his lap, pale long legs trapping Bakugou’s hips, as Shouto’s bare lower half grinds deliberately over the apparent bulge. Fuck, he should’ve undressed fully he thinks, as Katsuki reaches up to wipe the back of his hand over his forehead.
Why is it so fucking hot in here?
“I never thought I’d get you all to myself, Dynamight.”
Shouto’s voice brings him back to the alluring view above him. A freckled shoulder comes into view as the stretched neck of his sleep shirt slides off. Lower, the hem of it tents up as Shouto’s length pokes at the fabric, no doubt aching to be touched, but pretty boy seems to have other ideas.
Katsuki grabs him by the thighs, squeezing appreciatively over the strong muscles there and rocks Shouto back and forth over his still clothed hard dick.
“I said you are my prettiest fan. It wouldn’t be heroic of me not to show how fucking grateful I am, would it, princess?” His voice drops to a low groan, akin to the way it sounds with the voice changer embedded in his suit, but still recognizable enough.
Shouto is visibly affected by it, eyes falling shut as he attempts to stabilize himself. Katsuki is under the same predicament – dying inside to fuck his boyfriend already – but they are both holding back, convinced the pleasure will be intensified the more their little foreplay keeps going.
“And I told you I have a boyfriend, and yet here we are…”
A smug smile replaces the trembling of Shouto’s reddened lips, his eyes looking darker than ever. A shockingly cold hand finds leverage right over the sheen of sweat settled on Bakugou’s chest, and the blond immediately finds relief in the touch. It’s normal for him to run hotter because of his quirk, but for him and Shouto to have such a contrast in body temperature…
Before he can get another word in, Shouto supplies his own scenario.
“Though I suppose you two look alike.”
His left hand reaches forth to caress the side of Katsuki’s face as if he’s really looking at him for the first time. Takes in the curve of his jaw, the slope of his nose and the roundness of his lips.
He thinks Shouto misunderstood his request, but he’s quickly proven otherwise.
“Your hair is messier, Dynamight.” Both hands reach up to tangle through ash blond locks, ruffling them up, dull nails lightly scratching at his scalp. “Actually-“ Shouto tilts his head, a put on calculating look on his face “-Katsuki only looks like this after he’s fucked me good.”
It takes him aback, a fizzled out breath punched right out of him. Shouto’s messing with him right now, and Katsuki can’t say it’s not turning him on more and more with every word.
His boyfriend’s hands chase the shape of his face and thumb over his lips. Just to bite back, without words, as now Shouto’s running the show – for the moment – Katsuki parts them and kisses his finger, not without licking it after, making sure to leave a wet trail behind.
He smirks cockily when he notices the shirt moving under the twitch of Shouto’s dick.
“Too bad I can’t see your face under the mask, Dynamight.” Shouto continues on, like he isn’t on the verge of coming all over himself. “How would I know…” he sounds short of breath, like he does when Katsuki’s balls deep in him and Shouto’s holding on for dear life onto the ruined sheets “…if you’re a better kisser than my boyfriend?”
He’s leaned close enough for their noses to brush, shirt slipping from where it was covering his perky ass. Katsuki takes full advantage and palms both cheeks, tipping Shouto even closer.
“Kiss me and you’ll find out, princess.”
It’s a filthy kiss, so much different from the first one they shared tonight. Shouto is moaning in his mouth, shamelessly rubbing himself over Katsuki’s abs. Precum droplets stain his skin, his own cock drooling and making a fucking mess in his briefs. Fuck, he has to get them off.
Shouto doesn’t pull back until his hips stutter and his voice cracks into a needy whine, so close to coming but halting his movement right before he could spill all over Dynamight. Twin flushed cheeks greet him when pretty boy pushes himself away, the red hue trailing down to his chest.
Licking his lips, chasing the aftertaste of Shouto’s pretty mouth, Katsuki asks “How do I measure up, gorgeous?”
The amused smile that follows his question isn’t exactly the reaction he thought he’d get out of Shouto, but his boyfriend humps hard on his cock until it catches between his cheeks, pulling a strained moan out of Katsuki.
“I’d say- ahh you’re pretty big, Dynamight.”
“Think you can take me, princess? You feel really tight, baby.”
There’s no need to ask, as Shouto’s proven him how much he can take, but technically, Dynamight wouldn’t have any way of knowing that.
“Don’t worry about that, Dynamight. I think I can take both you and my boyfriend.”
Shouto laughs, short and silly, like he’s in on a joke only he knows, and Katsuki is once again left baffled at his boyfriend’s charm.
The journey of Shouto’s hands take him to Bakugou’s chest, where he squeezes his pec the same way he had his ass squeezed by Katsuki’s hands a few moments ago, thumbs reaching to rub over his nipples. Pretty bastard knows how sensitive his chest is, and still goes in with that little shit smirk of his.
“I always thought your shirt is pretty tight, Dynamight. It really brings out how big your tits are.”
This time he pinches his nipples, and Katsuki bucks up into his ass.
“Fuck you, they’re not tits, Shou!” He snarks, but Shouto doesn’t look deterred in the slightest. It’s not the first time he gets reprimanded about it. “You have a thing for my chest, pretty boy?” So he changes his route.
“Hmm, it feels good to play with, is that why you look at my ass so often, Dynamight? Don’t think I didn’t notice, you stare a lot.”
Shit, does he? It’s only natural for him to admire Shouto, and oftentimes he doesn’t even catch himself when his eyes stray to find Shouto and lock on him. Even when he’s suited up.
“Don’t worry, I’ll let you fuck me.” Shouto’s usually the one who wines for it, begs for Katsuki to fuck him, or asks him to at the fucking dinner table like a freak. But now, he’s allowing Bakugou to do it, and the phrasing of his words wires a new sort of desire in his veins.
“I must be really lucky then, princess. It’s not every day I get to have my way with my prettiest fan.”
Finally, he reaches for the bottle of lube, and his dick pulses achingly like the feeling of the bottle in his hand has conditioned his dick to get ready to fuck Shouto. He’s gonna bust his load as soon as he gets inside him, and Katsuki doesn’t even feel embarrassed at the thought.
Shouto scoots backwards until there’s enough room for him to tug down the waistband of both Katsuki’s sweats and underwear, revealing the fat and purpling length of his cock. Shouto looks downright delighted at the sight, licking his lips and bathing his stupidly pretty eyelashes at it like it’s the first time he’s seeing Katsuki’s dick.
“You are really big, Dynamight.”
Shouto states, wrapping one hand – again, how does it feel so fucking cold compared to the rest of his body? – around the girth of it and pumping it up and down. He squeezes the base and whines high in his throat when precum oozes out and coats his tip.
Katsuki has to bite his tongue from quipping back at Shouto for doubting his size, but it’s just part of the damn scenario.
“I really want to suck you off, Dynamight, but I feel really empty…”
Yeah, there it is. The needy princess in Shouto. The moment he gets his hands or mouth around Katsuki’s cock he goes stupid for it, and all he knows to ask for is to get fucked. Shouto gets both hands on his cock and starts jerking him off languidly, big doe eyes trained on Katsuki’s face. His thighs tremble in time with the minute thrusts of his hips along the bed.
Something in him snaps, tight like a worn out rubber band, and Katsuki flips their positions. Shouto moans out at being manhandled and his legs automatically twine over the small of his back.
“I’ll take care of you, princess. Gonna show you how Dynamight fucks.”
The process of prepping his boyfriend is sloppy and hurried, both too strung up to take it slow and enjoy the stretch of Shouto’s rim around the thickness of his fingers, but he opens up so easily, eager to swallow more of Katsuki with each added finger.
“Fuck, I didn’t know you were this hungry for Dynamight’s cock, pretty boy. Should have fucked you way earlier.”
Shouto nods, sounding desperate to get him to push inside, if the needy mewls and pleas are anything to go off. He’s thrusting his ass back onto his fingers, the wet squelch of them meddling with the panted breaths and his pretty boy’s heady moans.
“I’m ready, Kats- Dynamight…c’mon, fuck me, please!”
While he’d love edging Shouto more, getting back at him for his earlier teasing, Katsuki feels like he’s going to explode – he hopes Shouto can’t hear the way his palms are popping against the sheets – so he lathers his cock with lube and pushes inside in one go, knocking all air out of Shouto.
“Yess, Dynamight, shit- I knew you’d feel good. So big, Dynamight…move, please please please, move-“
His thrusts are erratic and uncoordinated at first, until Shouto stops squirming around like a needy princess and lets Katsuki settle a pace. It’s actually real fucking sweet, how messy they get when having sex, how it’s sometimes unpredictable, how they find out more about each other with every night of love spent together.
Discovering that Shouto wants to get fucked by his hero persona wasn’t something Katsuki had expected, but he had hoped his boyfriend would have some sort of positive inclination towards Dynamight.
What they’re doing right now is going to complicate his reveal even more, but Shouto looks like he’s enjoying himself immensely. Maybe he won’t get mad at Katsuki for keeping this from him.
“So tight for me, princess. Are you sure you can take more than one cock in this pretty little hole of yours?”
Fingers come to rub over the stretched rim, teasing the places where the furl of muscles gives out, close to pushing one finger in alongside his cock, but never fully committing to it. Shouto’s not stretched enough for that, and while he doesn’t mind it when it hurts a little, they’re both too high with arousal for it right now. Besides, Katsuki’s been leaking like a fucking faucet all over Shouto’s walls with how good he sounds – he might not last that long.
“I c-can, m’not tight, you’re- haah Dynamight, you’re stretching me out right now.”
Course he’s not tight anymore, not with Dynamight’s fat cock shoved inside him.
“You’re so fucking cute, princess. Are you close? Want Dynamight to make you come?”
Shouto is too far gone to form coherent words anymore, a string of Katsuki and Dynamight’s name lost in the babble of mewls and sweet little ah ah ahs, so he nods his pretty head and guides his hand to wrap around his drooling cock.
Katsuki would have loved to make him come untouched – Shouto always squirts so fucking much then, all the way up to his chest, dirtying himself with cum – but he complies and jerks him off in time with his thrusts, thumb rubbing over the sensitive slit to see him arch his back and toes curl into the sheets.
“Dynamight, come inside, I know you want to-“ Shouto’s eyes roll back into his head when he comes, but he holds onto the last bit of coherence he has to grab at Katsuki’s face “I won’t tell my boyfriend, Dynamight. You can fuck your cum in me, I love getting filled.”
It’s game over for Katsuki then, as his hips jerk hard and he buries himself deep in Shouto, thick spurts of cum shooting inside him. Shouto claws at his back, red thin lines left behind from trimmed nails, teeth attaching to one of Katsuki’s shoulders.
The after high of his orgasm registers as a blur to Bakugou, he’s almost convinced he fell asleep, but he opens his eyes and he’s still inside Shouto, with his boyfriend’s nose stabbing into his adam’s apple. Pretty idiot always cuddles right in his fucking soul after they have sex – Shouto likes to call it making love, and despite the term sounding sappy as fuck, Katsuki has to admit he also prefers to call it that.
An unintelligible jumble of words thrums against his skin like a low vibration, and Katsuki has to nudge his boyfriend to speak up.
“What was that, Shou?”
Shouto moves away from where he tucked his face into his neck, but keeps his limbs around him, like some fucking koala backpack, or rather a boa constrictor.
(Either way, Katsuki absolutely loves it and doesn’t dare get Shouto to move)
“You could’ve told me you’re Dynamight. I wouldn’t have gotten mad, you know.”
At first, Katsuki thinks he didn’t hear Shouto right. The words register in his brain, but somehow they make no fucking sense.
“Hah?”
Shouto giggles at the baffled expression on his face and kisses the crease forming on his forehead.
“I know you’re Dynamight. You could have told me before fucking me while you pretended to be him.”
It all makes sense now, that Shouto knew who he was. He wouldn’t have flirted back with Dynamight all those times. And Katsuki definitely would not have pretended to be any other hero if he weren’t Dynamight himself.
“Why didn’t you say anything, dumbass? D’you like teasing me, princess?”
He wants to hide his face in Shouto’s hair, or smother Shouto with one of the pillows, but he’s not going to run away from shame this time. No matter how stupid he feels now after all that’s transpired.
“I had fun, and you look really hot with your suit on. I’m sorry if you didn’t enjoy it as much as I did, Katsuki.”
There he goes again, apologizing for being selfish and getting pleasure from Katsuki.
“Shut up.” Katsuki kisses him to shut him up and it works, until curiosity hits him.
“Wait, how did you find out?”
At this, Shouto’s gaze shies away and he tucks his chin close to his chest. Katsuki is having none of that, gripping his chin with two fingers and bringing Shouto to face him.
“Don’t be shy now, pretty boy. You can tell me.”
The encouragement and reassurance always does the trick, no matter how smug Katsuki goes about it.
“It’s just, your dicks feel the same.”
That’s- not at all what Bakugou expected to hear.
“What- the fuck, Shou? When did you fuck Dynamight?”
Shouto goes to open his mouth to reply, but seems to get a better idea how to go about it, and takes advantage of their close proximity to slot their lips together. The distinct frost of cold is there, clinging to Shouto’s tongue as it glides over his own and fuck, of course that’s it.
Ice clings to Shouto’s white strands of hair and Katsuki doesn’t worry about the sudden spike of heat in the bedroom anymore.
He should have known his pain in the ass of a boyfriend was the same pain in his ass of a hero partner.
