eijirou being katsuki’s older, pro hero brother who everyone tries to get closer to via him.

and just when katsuki thinks someone—izuku—wants to come over for him and not for his half-brother, izuku’s rambling about ‘red riot’ this and ‘red riot’ that.

it pisses him off. fast.

he can’t help it when he slams his books on the table and yells at the top of his lungs, “if you only care about that bastard then go fuck off to his room!”

izuku’s eyes widened, and katsuki scoffed.

“go ride his dick like every other motherfucker who pretends to care for me.”

“k-kacchan—“

“apparently i don’t fucking matter!” he ranted. “even if i am the one who stands out the best and has the cooler quirk, it’s always him; so, go! i‘ll even take you to his damn room myself!”

before izuku could protest, katsuki was grabbing his forearm and pulling.

“just when i think i have my own idiot on my side, he turns out to be a little red riot stalker.” he grumbled, and izuku tripped over his own feet as he was taken up the stairs.

“k-kacchan, i promise i’m here for you! it’s cool that red riot lives here, but i’m here to see you.”

“yeah. right.”

“really! if i’m being honest... i love red riot, but i’m here to talk to you about our classes. i’m in your house so we can hang out together.” izuku explained, but katsuki ignored him. “don’t be like th—“

“oi! shitty hair! i have another shitty groupie for you!”

he pounded his fist on the door before sliding it open, and izuku fell on to his bottom after katsuki pushed him inside.

“lose my number, then go to hell.” he said before shutting the door and stomping away.

izuku yelled onto his hands as after the door shut completely.

“all kacchan ever does is think about himself! i understand people have used him, but does he seriously think that i’d do that to him? is his self worth so low that he can’t realize that i like him? ugh... he’s such a pain! he never lets me talk!” he rambled to himself.

“h-hey, kid.”

izuku froze, and he slowly turned his head to look behind him. there, on his messy bed, sat a shirtless red riot.

“o-oh my...” he mumbled as he scrambled to stand. “s-sir! i’m so sorry! kacchan’s insufferable and-and he won’t listen to me, so h-here i am! i’m so—“

definitely gonna continue this when i wake up. but uh... let me get some ideas first

looks like we’re doing top!krbk and bottom!deku... the flavor will be immaculate.

izuku’s nervous ramble is cut off by eijirou’s awkward smile and a, “you can relax. i just woke up and... you’re a little loud.”

immediately, he’s word vomiting an apology that causes the hero to flinch back.

“you don’t have to apologize!” he laughed. “just chill out, bro.”

eijirou ran a hand through his hair, and izuku stood up on his wobbly knees so he could begin his exit.

“kacchan’s convinced i’m only here for you.” he sighed, trying to keep his cool and not freak out again. “i’m sorry for waking you, sir, but he threw me in here and—“

“called you something along the lines of an escort or a groupie, i’m assuming?” eijirou rubbed his eye. “what a brat... with an ego as big as his, you’d think he’d be less insecure, huh?”

izuku’s eyes widened when he threw his blanket off of then stood up out of bed.

“can’t a man just sleep in without his brother trying to hook him up with his underaged friends?” he grumbled. “what time is it?”

he checked his watched in an attempt not to stare at the firm muscle of eijirou’s bare chest and stomach.

“i-it’s half past n-noon, red—uh, sir.”

the hero waved off his formalities as he rubbed the sleep from his eye.

“let’s just deal with my baby brother so i can go back to bed, alright? i had a rough day yesterday. i’m still exhuasted.” eijirou muttered.

“oh, right! you had a crazy fight with a villain the other day!”

izuku held open the door for him before eijirou could.

“it was all over the news, and i... haha...” he laughed nervously. “i was late to school because i wanted to watch it in person... but it was worth it because you’re so cool! your unbreakable move is practically unbeatable!”

“well, i wouldn’t say that. i’m still just a sidekick.” eijirou chuckled as he rubbed the back of his head. “but thanks. so you’re a fan, i’m guessing?”

“well, i love everything about heroes.“ he answered. “i actually have these notebooks i’ve been working on where i analyze—“

izuku cut himself off as he looked to the floor.

“actually, nevermind that. kacchan says they’re dumb, so it’s nothing.” he sighed. “they’re just notebooks where i um... write down fighting styles and weaknesses...”

“that’s pretty cool. just don’t go exposing mine, okay?”

he nodded as they approached katsuki’s bedroom door.

“i even have kacchan in one! i don’t know if you’ve ever seen him fight, but he’s amazing. the way he battles excels even some pros, and we’re just first years!” izuku smiled to himself.

“i’m sure he’s flattered by that.”

eijirou didn’t even knock before he pushed the door open, and izuku stood awkwardly by the entrance way as he barged into katsuki’s room.

“hey, pipsqueak,” he called, and izuku’s eyes widened as he teased him. “what’s all this i’m hearing about you being jealous of my fanboys?”

“get your naked body off of me!” katsuki yelled. “and who said i was jealous? as if! just go die you red haired loser!”

“don’t be like that!” eijirou laughed as he smashed his knuckles into his younger brother’s head. “i’m not even naked. i have shorts on.”

“get the hell off!”

izuku blinked as they wrestled around on katsuki’s bed, awkwardly standing off to the side as to not get in their way.

“you gotta be nicer to your friends, man. not everyone cares only about me.” eijirou defended himself and izuku after he successfully pinned katsuki down.

“you should’a seen the way he was talking about you, katsu.” he said as he leaned forward to whisper into katsuki’s ear.

“i-i—red r-riot, sir, you sh-shouldn’t say th-that to kacchan!” izuku stammered as he felt his hands shake. “it’s not like that! i swear! d-don’t make it—“

his palms began to sweat as he wondered what eijirou could be whispering to katsuki, and then looked around the room when katsuki’s crimson eyes drifted to him.

then katsuki laughed hard enough to shake eijirou, who was still on top of him, with his eyes screwed shut.

izuku has never seen a prettier sight as his bubbling nerves died down, and he couldn’t help but take a step closer as the anger in the air seemed to melt away.

“yeah?” eijirou chuckled. “am i wrong? tell me i’m wrong, bro. it’d never work! you know you win in that area!”

“you dumbass, i win in every area!” katsuki pushed against eijirou’s face. “you’re just a pussy.”

“you are what you eat.” eijirou stuck his tongue out, and izuku covered his mouth as his stomach twisted. “tell your girlfriend my door is always open... just like my arms.”

“you’re so disgusting.” katsuki used an explosion against his bare chest, and izuku noticed how eijirou seemed to have been expecting it.

“h-hey, kacchan?” he spoke up, and a twin pairs of ruby eyes shifted to him. “are you still mad at me?”

“well no shit, deku.” he deadpanned.

“e-eh? what do i have to do to prove that don’t care about red riot as much as you?” izuku blurted, and eijirou’s head shot up.

“hey now, don’t drag me down to bring him up. we both know you like me... deku, is it?” he asked. “you don’t have to pretend for this insecure brat.”

“i wasn’t insecure, okay? i was just... testing him!” katsuki snapped.

“mhm. okay. and i’m a natural red head.” eijirou snickered as they began rolling around on the bed again. “don’t be so worried, baby bro. i know you better than anyone, so let me tell you a secret, ‘kay?”

izuku crossed his arms as he leaned against the wall, wondering if he was even needed—or wanted—around them anymore as they whispered to one another again.

should he leave? was he imposing?

he already started problems just by mentioning heros, so maybe he should just leave.

katsuki’s just so easy to set off, and the last thing he wants is to say the wrong thing and have him blow up again.

“oh, go to hell!”

“just hear me out, katsu!” eijirou huffed. “now stop fighting me before i actually start trying to pin you down! we both know i can.”

izuku turned away, not wanting to watch as eijirou pressed his bare chest against katsuki’s chest to get closer.

it’s so wrong, especially when eijirou’s putting both of his friend’s wrists into just one fist effortlessly.

katsuki’s strong, but not more than his brother.

and oh... right.

heat blossomed across his face as his eyes shifted to the wooden flooring.

brothers. the two of them are brothers.

maybe it’s because he’s a single child, but do siblings usually joke around like that with one another? are they really that comfortable?

he’s not so sure, but he knows that he definitely shouldn’t be feeling this way over the both of them.

it’s wrong to feel so tingly while watching one of his favorite heroes pin down the guy he likes, who just so happens to be his baby brother.

how old was red riot again?

twenty-two? twenty-three?

the information he knows about him is slipping as the bed creaks and squeaks underneath eijirou and katsuki’s combined weight once again. but does it matter?

he’s leaving. he has to before he says or does something that he can’t take back.

but before he could take a step out of the door, a sharp voice made him freeze in his spot.

“oi, nerd,” katsuki called after him. “just where the fuck do you think you’re going, huh?”

“i-i just... didn’t you w-want me to leave—“

“stop with the damn mumbling.” he cut him off.

“my um, mom wants me home so i—“

“what’s the matter, deku?” eijirou asked, and he squeezed his eyes shut as none of his words seemed to register to the two of them. “do you want to ride me?”

“do i want to do what?” he squeaked out.

he jumped when a pillow landed by his feet.

“do you want to ride with me? like... in my car?” eijirou repeated.

izuku let out the heavy breath he was holding. he must have heard wrong.

“if you want to go home, i can drive you. it’s no big deal. besides, whatever i can do that katsuki can’t, i like to rub in his face.”

“oh, he’s not fucking leaving until i say so. get over here, shitty nerd.” katsuki replied. “your dumbass came over for a reason, didn’t you?”

“will you stop terrorizing your friends, katsuki?” eijirou scolded, and izuku turned around to face them as he picked up the pillow.

he squeezed it in his hands, now noticing that katsuki had somehow climbed on top of his brother and had his hands pinned behind his back.

“don’t be a damn stranger, dumbass.” katsuki curled a finger towards him. “if you don’t want to fuck my brother, why are you here?”

how can he just say something like that? it’s as if they’re totally normal words to tell someone!

“i wanted to spend time with you.” he awkwardly answered.

things have gotten better between them since their fight at ground beta. everyday it feels like they take a step forward.

so when he jokingly brought up visiting his house for the first time in over ten years, he didn’t necessarily expect to actually be in his house, or his room.

“gay.”

“huh?” izuku gasped, his cheeks burning red hot as he squeezed the pillow tighter. “that’s—i’m—don’t say that!”

“nothing’s wrong with liking boys.” eijirou smiled as he rolled over, effectively throwing katsuki off of him. “to be honest, i think i like dating boys more than i like dating girls.”

“you fucker,” katsuki scoffed. “all the boys and girls in the world, and you’re still single.”

“ouch, baby bro.” eijirou held his own chest. “that hurts. but if you’re so concerned, maybe i should take up your offer and sweep little ol’ deku off of his feet. you wouldn’t mind, would ya’?“

“touch him and you die.” katsuki grit, and eijirou threw a wink in his direction.

“c’mon, baby. wanna ditch?”

izuku tensed, looking between katsuki and eijirou as he practically tore into the pillow with his nails.

“i-i—my mom wants me home.” he panicked before dropping the pillow and turning on his heels. “gotta go.”

“you lying sack of—”

“i was kidding!”

he heard the two scramble to chase after him as he ran down the stairs, nearly eating it on the last few steps when his sock slipped against the hardwood.

oh god.

oh geeze.

a shirtless red riot just winked at him and flirted with him, and katsuki actually wants him here.

‘he can’t leave until i say so,’ that’s a good thing. maybe. possibly.

it’s better than him kicking him out the door and yelling that he never wants to see his face around here again.

but if anyone else ever said that to him, he’d probably be a little worried for his life.

“ah, man! katsuki, this is your fault!”

“you’re the pervert who just had to flirt with the virgin nerd. you know how that always goes! stupid deku has never even had someone crush on him before!”

deku’s eyes widened when he felt someone just barely grab his sleeve.

but despite the hold being just a few fingers digging into his uniform, the force of the pull was strong enough to make him stumble backwards.

“looks like i’ve caught the runaway nerd.” katsuki announced, and izuku sucked in a breath when he felt his hard chest against his back.

“just where the hell did you think you were going, huh, deku?”

“home?” he tried.

“i wasn’t born yesterday. where do you think our mom is today?” he asked. “she’s a housewife. she hasn’t worked a day since eijirou started living with us when we were in middle school.”

“yeah,” eijirou answered from behind them. “mom went to have a girl’s day. she said she’s tired of being around boys.”

“my dog needs me?” izuku lied.

katsuki snorted as he wrapped an arm around him chest, pinning their bodies together.

“you can’t even take care of yourself.”

his voice was right by his ear, and he jumped as he felt his heart throb from inside of his chest.

“now let’s try this again, shall we?” katsuki lowered his voice. “why’d you runaway, deku?”

“i—you...” he struggled to find the words to say without coming off as a creep.

“does my brother make you feel hot when he flirts with you like that?” he whispered, and izuku remembered his earlier tantrum.

“n-no! not at all! k-kacchan, i don’t...” he laughed nervously. “i wouldn’t feel that way towards him! he’s just a hero and all heroes make me nervous—“

“all heroes? so aizawa and all might could make you feel like that too?”

“no!” he rushed. “don’t say all might and aizawa. they’re like a dad to me. i don’t want to imagine either of them—“

“so it’s not all heroes.” katsuki reasoned. “just red riot, my older brother.”

“please don’t hate me, kacchan.” izuku shakily raised his hands to hold the arm against his chest. “i-i promise that i came over with the intentions of seeing and being with you.”

“if you had to pick a poison...” katsuki said, and he turned his head to look up at him. “who?”

“who?”

“damn. what are you, a parrot? repeating the question ain’t a damn answer.” he snapped, and izuku looked behind him to eijirou, who was leaning against the wall and watching the scene unfold.

“who as in... is my favorite? because you’re both so cool in your own way!”

“oh, katsuki, stop trying to prove he likes you more than me.” eijirou sighed. “that little inferiority complex of yours doesn’t make you act very manly.”

“can it, asshole. you’re so confident in yourself that you hide everything under some red dye.” katsuki retorted.

izuku shrunk back as the air became thick around them, and for a moment, he has never been more glad to be an only child.

how they can go from teasing to fighting so fast is beyond him, and if that’s what having siblings is like, he never wants any.

“guys?” he asked.

“yeah?” eijirou acknowledged, and katsuki held him tighter. “i’m sorry for arguing, deku, but you said it yourself; katsuki’s insufferable.”

“he said what?” he asked, and deku’s eyes widened. “i’m what, now?”

‘thanks, red riot,’ he thought to himself. ‘you’re a real hero.’

izuku swallowed thickly as he looked up at katsuki, who was glaring down at him.

“i-if i had to pick a poison...” he tried shifting the subject back to what it was originally to avoid a fight. “well i’ll die either way, won’t i, kacchan? does it really matter?”

“i guess not.”

his friend’s hand gripped his jaw, and he allowed him to tilt his head back further.

“but now you’ve just told eijirou and i everything we need to know.” he whispered to him, and deku swallowed thickly as his eyes dropped to his lips.

“and wh-what’s that, kacchan?” he worried.

“that we’re going to roast you on a spit,” his lip curled into a knowing grin as their noses brushed, “and you’re going to love every moment of it.”

his eyes widened at the crude, suggestive tone his voice carried.

“i don’t know why you look so surprised.” eijirou grinned.

“what? did you seriously think you were slick while checking me out?” he mused. “i’m ogled at everyday at work. i know a look when i feel it.”

izuku shifted in katsuki’s hold as he locked their eyes together, trying to figure out if he was really okay with something like this.

“don’t look at me like that.” he snapped before gliding his hand from his cheeks to his eyes. “in fact, don’t look at me at all.”

he nodded, and then closed his eyes as katsuki’s lips ghosted over his.

“kacchan.” he mumbled, blindly inching forward in an attempt to get closer.

“i knew you’d want this.” katsuki scoffed before pressing their lips together, causing his stomach to flutter. “damn slut...”

the mumbled insult made his face burn even hotter with a blush, and izuku gasped into the kiss as his other arm curled around his waist.

a gasp fell from his lips when katsuki bit down on his bottom lip, and soon the hand over his eyes left to grasp his tie.

it’s nothing at all like he has ever dreamt of over the years, and he’s milking every moment of it by pressing closer and closer until it hurts.

“hope you don’t mind if i join you.” eijirou’s voice shocked him into reality, and izuku felt katsuki hold on to him tighter as he grumbled.

“just don’t get in my damn way.”

with his statement came a pull of his tie, and he turned his body so their chests were pressed together.

“don’t worry. i’m not here for you, baby bro. i’m here for deku.”

“whatever.” he muttered under his breath.

he shivered softly when another pair of hands set themselves on his hips, and izuku’s hand reached out for eijirou’s loose hair when his lips brushed his neck.

“izuku.” he said against katsuki’s lips, feeling them as he smirked. “my name’s izuku.”

“you should have told me sooner.” he chuckled. “here i thought that you just like being degraded.”

“apparently it’s the name of a hero.” katsuki told him. “i say it’s the name of my bitch.”

“kacchan!”

a chuckle vibrated through his chest as he shrugged. “what? you mean to tell me that i’m wrong?”

“izuku.” eijirou spoke. “it appears that ‘deku’ is saved just for katsuki, so i guess i should stop calling you that.”

izuku nodded as his head shifted to the side.

“while we’re on names, stop with the formalities, alright? just ‘eijirou’ is fine, baby. unless you need a hero to save you. if that’s the case... red riot is right here.” he whispered into his ear before kissing the side of his head.

“let’s take this to katsuki’s room, ‘kay?”

“what?” katsuki snapped. “why my room?”

“your boyfriend then your room.” eijirou reasoned, and izuku felt as katsuki’s body tensed in front of him.

immediately, he tried to debunk the statement, but couldn’t find the right words.

“we’re not—kacchan and i aren’t—we’re j-just—“

“both of you need to shut the fuck up.” he grit, and izuku pressed his forehead against his chest.

somehow, even with his eyes close, he can tell the two are probably taunting each other with smirks, glares, and hidden messages behinds their words.

“let’s go upstairs, izuku.”

eijirou pulled away, and katsuki’s arms unraveled from around his body to give him his space to move.

“you’re a pain in my ass, shitty hair.” katsuki breathed out.

“no. i’m about to be a pain in your boyfriend’s ass.” he corrected, and izuku choked as his eyes snapped open.

“if you have a crush on me, baby bro, that’s a story for another time.”

“oh my god.” izuku muttered as he felt himself being tugged in the direction of the stars.

he can already feel the two of them using his body to out do one another, or to take out their frustrations.

“you’re sick.” katsuki snapped at him as he followed them. “did your dad drop you as a baby?”

“no, i got something you didn’t—a hug.”

“guys,” izuku broke up their bickering as they stood inside of katsuki’s bedroom. “is something bothering you two?”

crimson eyes glared at him.

“your clothes.” katsuki snapped, and his breathing hitched when his blazer was grasped in two smoking palms before being yanked off his back.

“banter is normal for us.” eijirou promised. “we already talked about this anyways.”

so that’s what they were whispering about earlier.

“just be glad that you don’t have a brother.” katsuki told him, and izuku reached for eijirou.

“alright, let’s get serious.” the hero smiled as he reached for his tie. “give me a kiss, baby.”

his eyes drifted to katsuki, who turned his head before sighing.

then he nodded.

“okay.” izuku caved, and his heart jumped in his chest when he was forced on to his tippy toes by eijirou pulling on his tie.

“you’re so small.” he mused as he bent over to close the gap between them. “i almost feel bad for what i’m going to do to your body, izuku.”

their lips pressed together, and izuku wrapped his arms around eijirou’s neck for better balance.

“don’t you dare fucking forget about me.” katsuki warned, pressing himself up against his back. “i’m the one you’ll always want. he’s just what’s trending. don’t get it twisted.”

“mm...” izuku moaned quietly when he felt a kiss being placed betwen his shoulder blades. “can you... can you touch me?”

the small request ended with katsuki’s hands cupping his chest and eijirou’s hand reaching between his legs, and he melted underneath their warm hands.

calloused fingers worked open the buttons of his uniform, and izuku pushed his hips back against katsuki‘s hips when they brushed his ass.

“is this what you were craving, deku? to be sandwiched in between us...”

his lips trailed up his neck, and he hummed softly in pleasure.

“yeah... kacchan.” he mumbled as his hands tangled inside of the messy crimson hair spilling over his fingers. “eijirou...”

taking advantage of his parted lips, eijirou licked across the bottom one before slipping his tongue into his mouth.

“mmf...” came his muffled moan after.

“well don’t say i never did anything for you.” katsuki growled lowly before grazing his teeth against his neck. “spoiled nerd.”

when his shirt was fully unbuttoned, his hands ghosted over the muscle on his stomach, causing goosebumps to pebble on his skin.

eijirou’s lip curled.

the hand that was cupping his cock through his pants tightened, and izuku broke away from their kiss to moan.

“you’re so hard just from a little kissing, baby.” he pointed out as his palm grinded against him. “you want us that bad then?”

he nodded, already breathless.

izuku’s head leaned back into katsuki’s collar, and he turned his head to nose up against his neck, a smoky yet alluring scent flooding his senses.

“i can’t wait to make you scream.” katsuki whispered to him, his blunt nails scratching down the expanse of his now-bare chest.

“you’ll see that even with this loser brother of mine here, i’m the one who’s better... who can make you feel better.”

eijirou chuckled, his lips brushing underneath izuku’s chin before trailing down his bobbing adam’s apple.

“r-red... eijirou...” he choked nervously.

the sharp edges of his teeth pricked his skin, and katsuki pulled his uniform shirt off fully before running his palms over his torso.

“don’t be scared of him.” he mused, slotting his fingers between the bones of his ribs. his other tickled close to his navel and belt buckle.

“shitty hair wouldn’t hurt you by accident.”

“what-what about on purpose?” he murmured, a quiet whimper leaving his lips when the hero bit the base of his neck.

“that’s just part of the fun, baby.” eijirou purred, looking up at him through his thick lashes and crimson bangs.

izuku moaned at the sharp burn of having his skin broken, unsure whether the droplets rolling down his collarbone was his own blood or the hero’s saliva.

but is it bad if he wants to feel it again?

eijirou’s tongue soothed over the lingering sting of the bite, and he hummed.

“but i won’t hurt you too bad, baby. after all, i’m not some kind of villain.” he flashed his signature grin while palming izuku’s hardened cock, squeezing painfully tight to draw a cry from his lips. “pain isn’t my thing. i just want to watch you fall apart is all.”

“yeah, hurting you is my job.” katsuki growled, and izuku‘s eyes closed when his belt came undone. “you know you love it when i treat you so roughly... why else would you stay?”

his voice is a whisper, just barely audible over labored breaths.

“why else would you want me?”

“kacchan...”

‘that’s not it,’ is what he wants to say, but can’t bring himself to voice when he sees that vulnerable moment end.

“so you better behave yourself.” he snapped at his brother, who just quirked an eyebrow upwards.

“unlike someone i know, i’m always behaved.”

izuku’s eye twitched at their bickering, and he groaned quietly as they tossed insults back and forth for the millionth time since he’s been here.

“leash kid.”

“lap dog.”

with a rush of strength, he placed both hands on eijirou’s chest, pushing him back on to katsuki’s bed.

“both of you,” he raised his voice, reaching one hand behind to grab katsuki by his uniform shirt. “can you stop trying to belittle the other already?”

he pulled, electricity crackling around his arm when he moved out of the way and shoved him right beside his older brother.

“neither one of you are better than the other!” he yelled. “if all you’re going to do is throw snide remarks to each other, i’m going home and i’m fucking myself.”

“you’re strong...” eijirou whispered, and katsuki’s lip curled into a smirk as he tore open his own shirt.

“you think you can toss me around, huh? like i’m some doll?” he lowered his voice. “don’t look down on me, bastard. i am not the one.”

“kacchan, did you hear a word i just said?” he groaned, looking between them as they eyed his body with a newfound thirst. “i’ll leave.”

“no, you won’t.” he shook his head as he stood back up. “because i’ll catch you, and you’ll let me like all the other times you tried to pass me up.“

his finger curled, motioning him to come closer.

“now bring that ass over here, you damn deku. we all know it belongs to me.”

izuku crossed his arms over his chest, eyes narrowed despite the heat burning in his cheeks.

“you never listen, do you, kacchan?”

“yeah? well, if you like me so damn much then what’s there to change?” he snapped, taking a step forward to grab him by the arm. “come here.”

he pulled, and izuku’s eyes widened when he was guided on top of eijirou’s lap.

“oh, that little show of power has me aching. grind that ass against me.” eijirou groaned, his hands settling on his hips as he kissed the back of his neck. “you continue to surprise me, baby.”

“i just want you both to touch me without fighting...” he sighed, and katsuki huffed.

“fine. we’ll bite our tongues.” he grumbled before tangling one hand into izuku’s knotted curls. with a pull, his gaze was immediately directed upwards. “look at me.”

“kacchan...”

“i’m taking all your firsts.” he decided, and eijirou let out a heavy breath against his skin when he squirmed on top of his lap. “so open your mouth for me, deku, and come swallow this cock.”

he did as he was told, dropping his jaw open for him as his brother squeezed his hips.

“you two are so cute.” eijirou smiled, and izuku felt his hips press closer to his ass. “young love is just so adorable.”

katsuki ignored his statement in favor of unbuckling his own belt, and izuku couldn’t help the red hot blush that began to spread across his cheeks.

“kacchan...” he gasped, watching as his uniform pants fell to reveal his black briefs. “eijirou...”

“we’ll take good care of you, just relax. you’re still so tense.” the pro-hero soothed, dragging his hands down his clothed thighs. “why don’t you stick that tongue out, izuku?”

he did as he was asked, and katsuki let out a quiet grunt as he forced his briefs down his thighs.

“o-oh...” he whispered, both hands holding on to the firm thighs in front of his face as his cock hung heavy and thick between his legs.

“there’s no way i-it’s gonna fit.”

“sure it will, just use that strong determination of yours.” katsuki chuckled as he pulled on his head, guiding him towards the head of his cock. “don’t give up until you’ve taken every fucking inch, or i’ll force it down.”

“you won’t.” he choked.

“we all know i will.”
