[incest kink; degrad.]

i’ve said it before, but kirishima sitting around his room with bleach hair and bakugou’s heart skipping over how similar they look.

crimson eyes. ash blond hair.

he doesn’t notice at first—kirishima points it out—but now he can’t stop thinking about it.

it’s impossible to get out of his head as he imagines sneaking around inside of their room, trying to squeeze in some ‘bad touches’ and quickies before mom and dad find out.

the two of them fucking like bunnies while their parents leave for a business trip or go out for the day.

this kink is why he has a folder of photos dedicated to kirishima pre-hair dye.

they’re mundane candids he sneaks when he’s not looking, though a few do have his boyfriend posing. nothing inherently sexy. him with laundry baskets, him just doing homework, things of that nature.

but after kirishima slathers red dye in his hair and ruins his fantasy, they get his dick harder than any nude he has of him.

maybe it’s disgusting to jerk off over a photo of kirishima as he eats a cherry popsicle, but he can’t help it.

because it’s dirty, it’s alluring.

the sheer taboo-ness of fucking someone who looks like he could be his brother is enough to make him cream inside his fist hard enough to nearly black out.

of course, he had never explicitly told kirishima that he wants to explore this kind of kink. that’d be embarrassing.

how would that conversation even go about?

‘i want you to call me your brother and fuck me like our mom is going to find out?’

by just thinking of that conversation going down, he can hear kirishima dialing the police or a rehab facility of some sorts to come pick him up.

so he keeps his fantasy to himself, glad that he can still act normal around his boyfriend and feel completely satisfied with their usual sex.

but when his hair dye begins to fade out and the black starts growing in, a part of him is desperate to scratch the itch under his skin.

and just his luck, his mother and father are flying out of the country for some kind of fashion week, meaning if he went home, it’d be just them.

just him and kirishima, an entire house to themselves, and all the time they want to fuck without the fear of getting caught.

when the time comes around for kirishima to bleach his hair, his stomach is in knots as he approached him.

“h-hey, wanna come to my house?”

“eh? but your parents—“

“won’t be there.” he cut him off, and kirishima tilted his head, ash blond strands falling in his face.

“can we go after i dye—“

“we can buy the dye on the way over there.” bakugou rushed, and kirishima awkwardly rubbed his head. “aren’t you all out anyways?”

his boyfriend shrugged. “i just... i’d feel more comfortable only leaving after my hair is red again, you know?”

bakugou looked down at the floor, one fist wrapped around the strap of his bag and the other stuck inside the pockets of his joggers.

“it’s not a big deal. you look fine.”

kirishima sighed. “katsuki, i would love to go to your house, but i want to dye my hair first, okay?”

“just wear a hat—“

“that’s not the point. red’s my color.” he reminded him, and bakugou felt heat bleed into his cheeks. “why are you being so pushy about it anyways?”

he shrugged, taken back only slightly when his handsy boyfriend forced his chin up and eyes on to his.

“c’mon, what’s up, bro?” he asked softly, and bakugou’s stomach fluttered. “is my red hair so bad that you can’t stand to be seen with me anymore?”

“no.” he immediately shook his head as he took in the blond bangs framing his face. “it’s not that. red’s fine! it’s fine...”

kirishima awaited a further explanation, silent yet encouraging with a small smile.

he shrugged, trying to play off his flushed cheeks and tightened stomach with a, “i just... really like the blond... okay?”

“really?” he wondered, and bakugou watched as his eyebrows furrowed.

“isn’t it a little weird? i mean... we look like we could be related. it’s disgusting to kiss someone you look like, right?”

oh.

suddenly, it feels as if he was punched in the stomach as his boyfriend lightly elbows him and laughs.

“we’re boyfriends, after all! not brothers.”

is it weird to want this? maybe.

he knows that it’s probably not normal, but did he have to say it like that?

“it’s... yeah...” he nodded, and kirishima cupped his chin before kissing his cheek, not noticing his slumped shoulders. “i guess it’s kind of gross...”

“exactly!”

he watched as kirishima reached into his wallet to pull out the money for his bottles of hair dye.

“could you do me a solid and get them?”

bakugou took his money before dropping his overnight bag on the floor, accepting that he’ll be leaving with a red head rather than a blond.

“yeah, sure. whatever.” he nodded before stuffing his hands into both pockets. “see ya’.”

before kirishima could reply, he was closing the door behind him just a little too hard, tears stinging in the corners of his eyes.

in a way, he was rejected the way he imagined he’d be.

laughed at and ridiculed.

it’s not his fault that he finds something so painfully sexy about fucking his boyfriend as he looks like he could be his sibling.

if he could give up on it, he would, but once he has his mind set on something it’s hard to steer away from it.

in the midst of his thinking, he doesn’t even realize he’s crying until someone set a hand on his shoulder.

hell, he didn’t even realize he made it to the elevator and down to the lounge.

“hey, kacchan, are you okay?” kaminari asked, and he shrugged him off.

“get lost.”

“why’re you crying? did you look in the mirror again?” he teased, and bakugou pushed him away as he giggled at his own joke. “cheer up! maybe you’ll have a glow up after high school and get all smooth and suave—you know, like me.”

“yeah, whatever. okay.” he scoffed at him.

kaminari doesn’t follow him, understanding that he needs space, and bakugou sighed as he wiped his eyes with the sleeve of his hoodie.

“stupid fucking eijirou...” he muttered to himself, and then pried the front door open. “making me cry over something dumb like a kink...”

——

it doesn’t take long to get to the store, buy his three bottles of crimson dye, and then get back to the dorms. thirty minutes tops, not counting his detour to buy himself more lube.

he used the last of it earlier when thinking about his blond boyfriend wrecking his ass.

and he’ll need more when he masturbates in the shower tonight as kirishima sleeps because no way could he let him touch his body after he indirectly called him disgusting in a non-sexy way.

he’s too humiliated.

though he loves kirishima and trusts him, he just needs some time.

“oi, shitty hair.” he said as he knocked on his bedroom door. “open up, i got your shit.”

when the door opens, kirishima’s got his blond hair in a ponytail and two bags on his shoulders.

“the fuck are you going?” he asked, watching as he pulled his hood on.

“uh... your house?”

bakugou narrowed his eyes at him, trying to piece together the puzzle that wasn’t making any sense.

“my house?” he repeated, and kirishima nodded. “did i not just walk four miles to get your fucking hair dye because you didn’t want to leave your room?”

“uh... i love you?”

his arms crossed over his chest, wondering what the hell could have changed in just half an hour.

when he didn’t respond, kirishima innocently rocked back and forth on his heels.

“thank you?”

his boyfriend leaned forward, now close enough to smell the mint on his breath.

a chaste kiss brushed his lips, and bakugou felt his face heat as he held out the bag for him to take.

“did i give you enough?” kirishima asked, and fished out the receipt underneath the bottles. “do i owe you?”

“of course not. you think i keep tabs on what i spend on you?”

kirishima’s lip twitched as he turned the strip of paper around.

“we’re dating.” he reminded him. “if you just asked me to go get your shit, i would have bought it with my own damn money. i don’t expect you to pay me back.”

“i love you... but um, katsuki? what’s the lube for?”

his eyes widened, and kirishima’s face burned red as he pointed out the charge to him.

“what the fuck do you think?” he muttered, ripping the paper from his hands before exploding it in his palm. “shut up. are we dying your hair or not?”

“well, if you like my hair like this...”

kirishima twirled a lock of his blond fringe around a finger before smiling sheepishly.

“i think i could... i dunno... milk this blond look for today just for you.” he said, and bakugou rolled his eyes as his face grew hotter.

now he’s suspicious.

‘for him,’ he said.

yet not that long ago he was saying that he didn’t want to do it because it makes him uncomfortable to walk around without his hair dyed a firetruck red.

interesting.

“i don’t need you to do jack shit for me. if you don’t want to do something, then don’t.” he snapped at him.

kirishima held his hand, and he looked down at their intertwined fingers.

“don’t do this if you think it’s gross.” he muttered. “it’s not a big deal, idiot. i don’t care what you do.”

“we can do it at your house then, as you said.” he beamed happily. “let’s get going.”

the bag was handed back to him, and he spun kirishima around to stuff it inside of his backpack.

“did you at least buy condoms?” he asked, and bakugou ripped the zipper closed, nearly taking it off completely.

“i said shut up about it, didn’t i? it’s not for you.” he huffed.

“who’s it for, if not for the both of us, then?”

“i ran out while touching myself this morning, is that what you wanted to hear?” he answered quietly, and kirishima pouted. “let’s just go. no more embarrassing questions.”

“you shouldn’t be embarrassed about that. i do it too.”

bakugou rolled his eyes, biting back his tongue because no, he doesn’t do it too.

kirishima doesn’t lie in his bed with three fingers inside of his own ass, fantasizing about his boyfriend fucking him rough and dirty with a hand against his mouth so their parents don’t find out.

because that’s disgusting, right? it’s weird, or whatever he said.

“it’s better together.” kirishima wiggled his eyebrows, and bakugou hit him on top of the head before making his way down the hallway.

“shut up.”

“you’re so cold.” his boyfriend sulked and he clenched his jaw.

“if you hate the idea of kissing someone who resembles you, what am i supposed to think about you suddenly deciding to stay my shade of blond for the day?” he snapped. “you don’t make any damn sense.”

kirishima huffed as the doors in front of them pulled apart.

“katsuki.”

when they got inside of the elevator, kirishima grabbed both sides of his face and then pressed another kiss against his lips.

it’s deeper this time around. with sharp teeth tugging on his bottom lip and his back smashed against the wall, he can’t help but gasp in surprise.

“i never hate kissing you, babe.” he said, and bakugou looked into his eyes as his bangs tickled his face.

“what’s gotten into you? you’re giving me fucking whiplash.” he muttered, and kirishima pressed one arm against the wall.

“boost of confidence, i guess.” he whispered.

“yeah, right.”

“alright, you caught me.” he sighed. “kaminari texted me, said he saw you looking sad after you left my room. i’m sorry. i didn’t think you liked the blond enough to be sad over it.”

bakugou shoved him off, and then crossed his arms.

“i don’t need your pity.”

“don’t be like that, bro.” kirishima huffed, and bakugou looked down at his hands as the stupid name made his stomach twist.

‘bro.’

he says it all the time to everyone regardless of age or gender, yet it makes him feel hot like it’s something special. something endearing.

fuck.

“do you like it? seriously?” he asked, and bakugou lifted his eyes. “like, be honest. how much do you like it bleached?”

“if you like it red then fuck what i think—“

“katsuki, how much?” he repeated, and the doors opened behind him.

caving, bakugou muttered, “a lot.”

“even if it makes us look related?”

that’s the only reason he likes it.

he sucked in a deep breath and then nodded, feeling calloused fingers wrap around his hands before slotting between his.

“you get one day.” he said. “don’t forget that i’m red riot, not blond riot.”

they left the elevator, and bakugou glanced at his boyfriend as they rushed their way to the front door, attempting to dodge their friends.

‘one day,’ he had said.

an entire day feels like a dream compared to the... what? ten minutes? twenty minutes? he used to get before.

but what’s the use when kirishima isn’t interested in what he wants to use it for?

it’s just torturing him at this point, taunting him with what he can’t have.

“uh... bro? why are you looking at me like that?” he asked, and bakugou turned away.

“nothing, j-just drop it!”

——

the train ride is boring, and he spent most of it admiring kirishima as his boyfriend watched out the window.

at one point, a vendor called them brothers while giving them a plate of takoyaki, which made his face immediately burst into a shade of scarlet.

and before kirishima could deny the accusation, he was tugging him away, murmuring a, “c’mon, ei.”

their walk to his house is quiet, but he could feel his boyfriend watching him as he pricks a ball off of his plate and chewed it longer than necessary.

“bro?”

a tingle ran up his spine, but he kept his eyes in front of him as kirishima followed.

“are you feeling alright? you’ve been acting a little off today.” he pointed out.

bakugou swallowed, then chewed on the edge of his toothpick.

“you’re blushing a lot when i call you ‘bro’.”

“i’m not blushing. it’s just a little warm out today.” he defended himself.

“you didn’t let me correct that guy when he asked me what my ‘brother’ wanted to order.” he continued. “and on top of that, you really like my hair for once.”

“look, there’s my house.” bakugou ignored.

kirishima huffed as he rushed up to his front door, immediately reaching for his keys.

“you can’t avoid the question, babe.”

“go ahead and put our bags in my room. upstairs, third door on the right, can’t miss it.” he avoided his statement, proving that he could do just that.

it’s easier to not bring it up, even if he has been doing a bad job at hiding his secret kink.

but then two arms are sliding around his waist from behind, and his eyes widened as a pair of lips brushed the shell of his ear.

“bro, are you really gonna ignore me right now?”

bakugou’s breathing hitched as the two of them stumbled through the front door, trying to get in before any neighbors could see.

“you went through all the trouble to get me here... so what’s the big deal, hmm?” kirishima continued, kicking the door shut behind him.

“ei, what are you—“

he’s cut off immediately.

“all alone... no mom and no dad... a band new bottle of lube that you say’s not for me to use on you... i just wanna understand.” he said, and bakugou lifted his shoulder to cover up his neck and ear.

this is dangerous.

his boyfriend’s an idiot, sure, but he knows what he’s doing right now with that low, suggestive voice and the tickle of his lips against his skin.

“you said that i’m giving you whiplash but fuck, i’m getting dizzy, baby.” he murmured, sliding his hands down his sweater.

bakugou pushed his head back into his shoulder, tilting his gaze so he could look at his boyfriend.

“call me that again.” he said weakly, only getting a cocky grin in return as kirishima kissed behind his ear.

“‘baby’?” he repeated. “i can call you baby all night, katsuki...”

bakugou shifted his weight from foot to foot, not yet courageous enough to tell him that’s the wrong name.

but thankfully,—or... unfortunately, thanks to his nerves—his boyfriend could tell he wasn’t liking it.

again, for an idiot, he sure does know a lot about him.

“don’t tell me you want me to call you ‘bro’.” kirishima breathed out, and he closed his eyes as he felt him begin to pull away.

great.

“that’s literally what i call everyone, katsuki. it’s not special at all!” he reminded him. “who tries to set the mood with ‘bro’?”

bakugou’s jaw clenched, and he turned his head before shrugging kirishima off of him.

there goes his mood.

“lets just bring our bags up to my room. forget about it.” he instructed him dully, and a hand grabbed his arm when he tried to walk away.

“w-wait a second!” he rushed.

“look, we need to talk about the elephants in the room, katsuki.” he asked, and bakugou’s fists tightened. “what’s up?”

“isn’t it obvious?” he grumbled.

kirishima was so close to getting it, wasn’t he? the pieces were all there. he just has to put them together.

“uh... no?”

he hung his head before smacking a palm against his face.

“then you don’t deserve to know.” he hissed before walking away from him. “just leave me alone. it’s nothing.”

“leave you alone? i’m in your house! what am i supposed to do? bug your neighbors? the takoyaki vendor?”

kirishima followed him to his room.

“tell me what’s going on with you, babe. one moment you’re looking at me like you want to jump my bones and the next you’re slamming doors! i don’t get you today.” he called after him.

“good! it’s best like this.” bakugou yelled at him.

he wrapped his arms around himself as he heard the thump of bags hitting the floor.

“it’s gross, so don’t bother. just drop it, alright? it’s better like this.” he sighed, and a hand pressed against his shoulder.

“katsuki, just talk to me. what’s going on?” he asked.

“i-i...” he struggled to get out. “it’s noth—“

“don’t tell me it’s nothing. be a man and spit it out already.” his boyfriend demanded, and bakugou glanced at his bed.

“i think... i think i have a-an incest kink.” he murmured, unsure if kirishima could even hear his confession.

“ever since i saw you with bleached hair and you said we looked alike, i-i’ve been fantasizing about us pretending to be brothers who-who do things they shouldn’t—“

“wait.” kirishima cut him off, and he gripped his arms harder. “wait wait wait. hold on. just-just wait, katsuki.”

bakugou squeezed his eyes shut, and felt the hand in his shoulder tighten.

“you... want me to be your brother—“

“no! w-well... yes, but no. absolutely not. it’s not like i want to fuck my dad!” he snapped over his shoulder. “it’s a-a roleplay kink. a fantasy.”

“dude,—“

“i knew you’d think i’m disgusting. earlier today you said it’s weird to kiss someone you look like.” he choked out. “forget about it, eijirou.”

“a roleplay fantasy? like... i dont know... uh, teacher and student? hero and villain?”

he nodded, and kirishima took a deep breath.

“is that why you were so upset earlier? because i said it’d be weird?” he asked, but bakugou refused to answer as he sniffled.

“and you picked a day your parents weren’t home to... set the scene?” kirishima noticed. “mom and dad are gone, so the two of us can finally play?”

bakugou swallowed the lump in his throat as he felt his boyfriend gently pull him back against his chest.

he’s warm, comfortable, but it feels so wrong now that he had spilled his guts to him.

“maybe...” he murmured, and one of kirishima’s hands cupped his jaw to turn his head.

“just what do you fantasize about then?” he asked quietly, and bakugou looked away from him despite the shiver inching up his spine. “your big brother taking advantage of you? or is it your little brother doing anything to please you? you know you’re older than me, katsuki.”

“don’t fuck with me.” he breathed out before pushing him off.. “d-don’t pretend to fucking be into it for me. if you hate it then just say so. don’t make fun of me, asshole!”

“do you think i’d ever intentionally make fun of you for something so important to you?” he scoffed.

one hand held his chin again, and kirishima’s calloused thumb wiped his tears away before kissing the back of his neck.

“all you had to do was talk to me, bro...” he trailed off. “i can’t read minds, you know. if you wanted me like this, you just had to say it.”

“eijirou...”

“i guess i did come off a little mean earlier, but i was just kidding. i didn’t mean to hurt your feelings, katsuki.” he promised, and bakugou wrapped his hand around the fist sneaking it’s way to his sweats. “just talk to me. what do you want, hm?”

“i want you.” he swallowed.

kirishima hummed as a hand reached to pull on his hair.

“g-god, ei... you don’t know h-how bad...” he gasped when sharp teeth scratched against his neck. “the things i imagined...”

“maybe i’d know if you told me.” he hinted. “or did you plan to keep getting off by yourself?”

honestly, yes. he did.

“i thought you’d think i was gross so i planned to... in the shower.” he admitted.

“there’s no need to touch yourself when i...” kirishima paused, then chuckled darkly. “when your brother—“

goosebumps rose on his skin.

“—is right here to do it for you.”

immediately, it felt as if his legs were too weak to carry his weight, and his shoulder twitched upwards in an attempt to close off his neck from him.

“fuck,” he choked out, pulling on kirishima’s hair as a pair of lips brushed behind his ear.

“c’mon... don’t hide.”

his shoulder fell, and he stopped the hand that was inching its way underneath the waistband of his joggers.

“there’s nothing to hide when it’s just you and me in this big ol’ house,” kirishima reminded him. “show your brother everything.”

“e-ei... but it’s-it’s wrong...”

sharp teeth bit into his neck and his jaw dropped.

“if it’s so wrong then why are you so hard, bro?” he asked, slipping his hand over the bulge inside of his pants. “you’re so fucking hard for your brother, and i haven’t even touched down here! are you that excited, katsuki?”

slowly, he tried to roll his hips into his hand, seeking any kind of friction and pressure he could get.

“our mom and dad leave and you’re suddenly acting like a total slut,” he accused. “what would they say if they saw you humping my hand like a bitch in heat right now?”

kirishima’s other hand wrapped gingerly around his neck, and one twitching fingertip forced him to turn his head.

“mom would kill us,” he breathed out, and he raked his eyes up and down the other’s face. “so d-don’t tell her. don’t tell mom.”

“like i’d ever ruin this for us.”

bakugou squeezed his fist, and a soft smile tugged on his boyfriend’s lips.

“my baby brother’s a little pervert, yeah...” he lowered his voice. “but what does it make me if i take advantage of that? c’mon, tell me what you want. tell your brother what you want him to do to you.”

a warm tongue brushed his bottom lip, and bakugou closed his eyes before opening his mouth for him.

“mm...” he hummed, guiding kirishima’s fist between his legs before squeezing.

there’s an ache in his stomach, hot and heavy. one he’s not sure he has ever felt before.

“i-i want,” he’s cut off with another sloppy kiss that’s all tongue and spit, “i want you to t-touch me.”

“you’ll have to be more specific than that, baby bro.” kirishima chuckled breathlessly. “i could touch... your cheek.”

instead of cupping his neck, his palm held his face.

“i could touch your hand.”

bakugou fought back a whine when the tight pressure around his cock left. those same fingers twisted to slot between his own.

“your ear.” he added, and his lips brushed the shell of his ear. “oh, and why don’t you say it right? show some respect...”

“my cock,” he blurted. “t-touch my cock, ei, p-please. i want... i need my big brother to touch me right here.”

he pressed the back of kirishima’s hand on to his cock, and then rutted his hips against his knuckles.

“i need you so bad. all day i needed you.” he confessed.

“didn’t you say you touched yourself this morning?” kirishima recalled, and he nodded. “naughty boy... you were thinking about me, weren’t you? putting those little fingers of yours inside yourself... wishing it were my cock fucking you stupid.”

“yes. god yes, ei...”

“imagining your big brother shoving you up against the wall, a hand on your mouth so mom and dad don’t find out—did any of our classmates hear?” kirishima asked. “did they hear you call out for me like the slut that you are?”

his head shook and melted into his chest.

“n-no, i promise. no one knows.” he rushed out as kirishima’s hand pulled away from his to tug on the drawstrings of his pants.

“let’s get these off, yeah?”

bakugou pushed the waisted down, a sigh of relief leaving his lips once they’re pooled around his ankles on the floor.

“you’re wet down there,” he noticed, and his eyes drifted to where there was a darkened, damp patch of cloth in his briefs. “i don’t think i’ve ever gotten your cock drooling like that so fast and so easily... katsuki, i haven’t even touched you skin to skin yet.”

“don’t stare!”

he shifted his weight from foot to foot while stepping out of his pants, then kicked them across the room.

kirishima laughed as his face heated to a bright red.

“don’t get all shy and embarrassed, bro. it’s so fucking sexy that you want me this bad.” he said, which didn’t help.

it only made his flushed cheeks even hotter, and he hid his face into the crook of kirishima’s neck.

“sh-shut up,” he murmured, and then sucked in a sharp breath when a hand squeezed down around his aching cock. “e-eijirou,—“

“i can feel you twitching in my hand, how cute...”

bakugou squirmed in his grasp, whimpering when he began to rub him through his boxers.

“get on the bed, baby. i’m gonna fish that lube out of my bag.” he instructed. “don’t touch yourself though. that’s my job, you got it?”

“y-yeah,” he nodded quickly. “got it...”

kirishima unraveled his arms from his body, and bakugou sat on the edge of his bed with his legs spread and arms stretched behind him.

“turns out this lube was for me, huh?” he teased as he unzipped his overnight bag. “don’t lie to me, katsuki. you were planning this.”

“s-so what if i was?” he murmured. “mom and dad aren’t here. we can do whatever we want, wherever we want, for as long as we want.”

once the bottle was in hand, kirishima shoved the bag away and grabbed one of his legs.

“you’re such a brat. it’s always your way, isn’t it?”

bakugou swallowed thickly as his legs were pulled around kirishima’s hips, forcing them open.

“fuck,” he whispered at the show of power before looking up at his boyfriend. “hey, take your hair down, eijirou.”

“hm?”

“take your hair down.” he repeated, and kirishima nodded.

he reached one hand behind his head to roll the elastic out, and he chewed on the inside of his lip when light blond hair fell on to kirishima’s shoulders.

“is that better?” kirishima taunted, and bakugou fisted his blankets as he rocked his hips down on to him.

“mhm...”

he pushed his bangs out of his face before grasping on to his hips, playing with the elastic band of his briefs.

“these can go now too...” kirishima decided, dipping his fingers under the band before pulling. “all they do is get in my way of me seeing all of your pretty body.”

bakugou reached behind his head, fumbling with his hoodie before yanking it overhead, leaving him naked on his bed.

when kirishima’s eyes raked over his exposed skin, he ran his own hand down his chest as he leaned back.

“do you like looking at me, ei?” he whispered.

while cupping his own chest and squeezing the firm muscle, he continued.

“does it make you proud that-that your little brother is this desperate for you?”

“you know i love you... especially when you act a slut.” kirishima’s lip curled, and bakugou laid back into his mattress.

“yeah?”

one of the hands on his thighs lifted, and bakugou cried out when it smacked against his skin, leaving a burn in its wake.

“but you’re my whore, aren’t you?”

he nodded quickly, so quickly that it felt like it’d scramble his head.

“y-yeah, i-i’m my brother’s whore.”

his back arched high off of the bed, both hands gripping the bedding in a tight fist before pulling.

“damn right.” kirishima nodded, rubbing the lingering sting in his thigh before lifting his hand once again.

this time it landed deeper inside his high, and his hips jerked.

he squeezed the comforter harder, hiding half of his face inside of his shoulder while the other half peered down at his boyfriend.

“look at that cock jump,” kirishima chuckled, running one calloused fingertip along the thick, throbbing vein on the underside. “you like this.”

he does.

he really does.

but before he could speak, the words are stripped from his tongue, lost in his jumbled head as he watches kirishima’s hands leave his body to grab the back of his own sweater.

“it’s hot in here...” he murmured before pulling, taking his shirt with.

sweat rolled down his neck, pooling in the dip of his clavicle bone.

“that’s better.” he said, wiping his forehead with his clothes before tossing them behind him.

something fell over, bakugou could hear that much, but he doesn’t care in the slightest as he swallowed thickly.

“fuck...” he whispered, jaw dropped just enough for his mouth to feel dry.

“awh...” kirishima smiled innocently despite the dark haze in his crimson eyes. “you’re drooling, baby bro...”

he looked away immediately, trying to salvage whatever was left of his pride.

then, in a futile attempt, bakugou tried to close his legs, only for a hand to force his knees apart once again.

“ah ah ah... let me see it all, baby bro. you know it belongs to me. all of you belongs to me.” he reminded him, sliding his fingers down his balls. down his taint.

they pressed lightly, and he choked on a moan as his cock twitched.

“stop hiding. you know there’s no one to hear us.”

“i-it’s... oh fuck,” he practically whimpered when they pushed harder, a roll of pleasure washing through his already overwhelmed body, “embarrassing...—“

“but you’re leaking so much precum,” kirishima said, guiding his other hand towards his aching cock. “don’t act all shy when you need this. you need me, and i’m just trying to deliver.”

bakugou dug his heels deeper into the small of his boyfriend’s back as his stomach tightened.

the fingers on his perineum lowered, now sliding between the cheeks of his ass and close to his clenched hole.

kirishima rubbed against the puckered rim gently, pushing just enough to make him squirm but not enough to penetrate.

“stop teasing,” he begged. “i can’t take it.”

“but where’s the fun if i don’t, baby bro?” he asked, letting go of his cock to grab the discarded bottle of lube. “teasing you is my job, you know...”

the cap was popped off, and bakugou closed his eyes as the cool gel was slowly drizzled on top of his red hot skin.

slick rolled down the length of his cock and towards his ass, making an even sticker mess of his lower half.

then finally, fucking finally, kirishima’s finger rubbed the dripping lube against his asshole, massaging it in before slowly pressing his middle finger against it.

just that small amount of pressure is enough to make him grind down into his palm and try to force his finger inside.

he’s aching. throbbing.

there’s nothing more on his mind than being fucked dirty and rough by his boyfriend as he continues to call him his brother. nothing.

if he’s being honest, that’s how it’s been for awhile now. a long while of indirect teasing and hiding.

“please,” bakugou’s breathing hitched when kirishima pulled his finger back. “please, eijirou. i-i need you so bad... stretching me open and using me, claiming me... please.”

“you beg so prettily.” kirishima sighed happily before inching his finger inside. “how can i say no to my precious little brother? look at him, damn near in tears just for my fingers.”

his moan broke midway through as a thick, lengthy finger filled him down to the knuckle.

“yes,” he gasped, and kirishima rubbed up against his clenching walls before curling it. “mm... ei...”

“you take it so well. what a filthy little boy, sucking in my finger like you never want to let it go.” he exhaled heavily, pressing his thumb directly against his taint.

bakugou moaned loudly, a violet shudder running through his veins as he rolled his hips closer. forcing his middle finger deeper and his thumb to push harder.

“i-i’m always good for you,” he defended himself weakly, and kirishima met his half lidded gaze through their bangs.

“yeah you are.” he agreed, pumping his finger in and out as bakugou reached a hand down to brush his fingers just below his boyfriend’s navel.

his index dipped under the white elastic waistband peaking from his black cargo shorts, then snapped it against his tan skin.

“i wanna touch you,” he said, panting softly as kirishima rubbed his middle finger against his prostate. “i want to see a-all of you... please.”

caving, kirishima moved one hand to the button on his shorts, still focusing on massaging his prostate and making him writhe.

“look how hard you’ve made your big brother, katsuki.” he instructed once his shorts fell, leaving him in just a pair of grey briefs with a wet patch on the thigh.

seeing his boyfriend’s arousal feels like validation of some sort, like he’s not just doing this to please him.

it makes him hotter all over, and he dragged his fingers towards his bulge.

“me?” he asked, feigning innocence as he stroked the length. “you’re like this... for me?”

“a-all you, baby bro.” kirishima’s breathing faltered. “fuck, you don’t know what you do to me, katsuki.”

bakugou pinched just beneath the head, then hummed in victory.

“you don’t know how hard it is not to sneak into your room late at night and fuck you into your bed.”

a second finger rubbed up against his slick rim, digging inside without a warning and making him whine.

“to pin my... my little brother down and take him until i’m satisfied.”

bakugou cried out when two fingers were slammed knuckle deep inside of him, not giving him a second to slowly adjust to the stretch.

“but you’re just so loud... you know?” kirishima pointed out.

“ei, please.” he begged as two fingers began to thrust in and out of him, scissoring apart to force his plush walls apart even further.

“that’s why i’m glad we’re here all by ourselves...”

both fingers then rammed directly against his prostate as his thumb massaged his taint.

“a-ah!”

“i can play with you all day... all night... as long as i want and listen to all those cute little sounds you make.” kirishima raked his eyes over the rapid rise and fall of his chest.

“i wanna cum.” bakugou whimpered, squeezing kirishima’s cock through his briefs.

his hand pulled the elastic waistband just below his balls, and he immediately wrapped his fist around him.

“i wanna cum o-on my big brother’s cock—eijirou, please.” he begged, trembling on top of his bed. “look how hard you are... don’t-don’t you wanna fuck me too?”

kirishima groaned, head hung low as he watches his own cock twitch from within bakugou’s tight fist.

“of course i do. that’s all i want... you know that.” he answered, and bakugou’s eyes rolled back as the fingers inside of him stretched apart once again.

“then hurry up, ei...”

“such a needy little slut. can’t stand a second of not being stuffed full of my cock.”

“i’ve been waiting for so long,” he whimpered, voice weak and trembling as he tried to keep from cumming.

kirishima pulled his hand away slowly, twisting one last time with scissored fingers.

“i know, baby,” he cooed, hooking against his prostate in the way out just to watch him writhe on the bed.

“i’m gonna cum,” bakugou whined as his hips jerked off the mattress. “o-oh fuck, i wanna cum so bad, eijirou. please, j-just put it in already. fuck me on your cock.”

kirishima just hummed as he reached for the lube, ignoring his aching, dribbling length and empty hole that’s now clenching around nothing.

he misses being filled already, and staring at his boyfriend’s thick cock isn’t helping the hunger burning deep within his veins.

he poured the cool slick on to his cock, and bakugou began to pump his fist, wet squelches filling the room.

but just before he could guide the wet head of his cock to his desperate hole, there was a buzzing beside him.

slowly, their eyes drifted to his discarded hoodie.

“what’s that? your phone?” kirishima wondered.

“yeah...”

bakugou’s the first to tear his eyes away, instead fixing them back on his boyfriend.

a gentle tug had his knees buckling, and his lip curled into a grin as kirishima chuckled.

“can’t even wait a moment, can you?”

“mm...” he hummed while shaking his head. “i’ve wanted this for so long, ei, please. all the times i-i touched myself imagining now... you can’t hold back on me. we’re so close. i’m so close.”

“i bet you’ll cum just from me putting it in, huh? naughty boy...” kirishima tsk’ed.

then his phone began to ring.

“christ,” he muttered, reaching his clean hand over to slam against the device. “who the hell is—“

“think it’s mom?” kirishima cut him off, and bakugou’s stomach tightened as he looked up at him.

“ei...—“

he doesn’t know what he’s doing to him.

of all the things he expected him to say, he wasn’t counting on him playing the distraction into his hands.

but he did, and bakugou’s about to cum untouched under kirishima’s eyes.

“she’s probably just trying to check up on us, you know... nothing to get mad over, baby bro.”

the fist around his phone clenched, and he bit back a whimper when the head of kirishima’s cock pressed against his ass.

“trying to make sure her little boys are playing nice.” he said, and bakugou closed his eyes as his phone continued to buzz. “i’m being nice, aren’t i?”

instead of pushing into him and stretching him open on his cock, he’s teasing.

up and down, he’s rubbing against his hole but never pushing in, much like when he was getting ready to finger up.

“your big brother’s always so nice to you... isn’t he, katsuki?” kirishima taunted.

his head shook, and the buzzing died down for a moment. a second for their mingled, heavy breaths to fill the other’s ears.

“you’re mean to me.” bakugou corrected him, grinding back against his cock to slip it in. “so mean, e-eijirou. all you do is tease me... you’re a bully.”

“a bully? me?” kirishima parroted, quirking an eyebrow upwards. “and what are you gonna do about it? are you gonna go cry to mommy and daddy? tell him that big brother eijirou won’t fuck your sloppy hole the way you want?”

“maybe i will...” he whispered, and their eyes met.

“spoiled brat.”

the blunt head of kirishima’s cock pushed against his puckered rim, and bakugou grinned in victory as his eyes shut.

“can you feel that?” his boyfriend asked and he gasped as his body opened up for him once again. “my cock sliding inside of you so easily...”

a wave of pleasure washed over his body, tingling from his curled toes to his clenched fists. heat pooled deep in his stomach.

“you were just made to take your big brother’s cock, katsuki.” kirishima grunted, and bakugou felt his own cock twitch, precum rolling down the side.

two hands cradled his hips, lifting them higher off the bed before squeezing, bruising his porcelain skin.

“so tight... so wet... opening up so perfectly for me.

“e-eijirou...” bakugou’s breathing hitched as he let go of his cock to press on his stomach. “fuck. oh fuck.”

his hips jerked upwards in pleasure just shy of overwhelming as he’s slowly split open.

then his phone rang once again, and bakugou nearly blew up the device on the spot.

“just fucking silence it.” kirishima hissed, and bakugou picked it from his hoodie’s front pocket.

as soon as his eyes fell on to the screen, he could feel the puffy walls of his ass clench and his cock throb dangerously.

“dad...” he whispered, and kirishima looked up at him as his hips stilled, leaving half his cock buried inside of him. “i-it’s dad, eijirou.”

he silenced the call, watching as the contact soundlessly lit up his screen.

“ignore it.” his boyfriend muttered, and bakugou sucked in a deep breath as he felt the cock inside of him begin to move. “unless you want him to know of all the slutty things you beg your brother for.”

slowly, kirishima pulled out, dragging each thick inch against his ass and making his jaw drop.

“which, if you wanna act like a whore, maybe i should treat you accordingly, baby bro.” he lowered his voice. “i’ll break you so no one but your big brother can use this little hole.”

bakugou’s legs spasmed when his boyfriend slammed their hips together, finally bottoming out and finally pushing him over the edge of ecstasy.

“i’m cumming!”

a sharp cry left his lips, and he grabbed on to kirishima’s arm as he felt a dribble of cum leak from his own cock.

“sh-shit, you’re squeezing me so tight, katsuki. so f-fucking tight.” he grit, blunt nails cutting into his hips for purchase.

“o-oh god, e-eijirou... oh fuck. you’re so d-deep. it’s so good—“

his voice broke, and kirishima grinded his hips deeper into him to milk his orgasm.

“untouched?” he mused while letting out a heavy breath. “my baby brother’s so amazing, isn’t he? cumming this hard from me just putting it inside him...”

there’s a ringing in his ears that’s not from his phone, and he feel the ropes of his own cum pool on his stomach and thighs.

it’s hot and sticky, dripping down his body and dirtying the blankets he’s lying on.

“look at this mess.” kirishima noticed, using two fingers to wipe some of his release off of his body. “and you didn’t even ask if you could cum. i’m always in charge, katsuki. you know that.”

bakugou’s tongue rolled over his bottom lip so he could push his fingers inside, and he cleaned his own cum off of his hand as kirishima began to fuck into his sensitive body properly.

“make it up to me by making me cum too, okay, baby bro?”

a whimper bubbled from his throat.
