“what the hell does it look like i’m doing?” katsuki’s long, soft fingers are cupping the fat of your thighs, keeping your legs parted no matter how much you try to squeeze them closed. your head is pressed into his chest, eyes fluttering as you strain to look at his face.

in front of you, izuku has both of your wrists locked in his own firm grip. he’s keeping one of your hands in place, forcing you to hold the buzzing vibrator against your clit as you pant and moan. he flits his eyes up to katsuki’s face, cocks his brow as he says, “it looks to me like you’re talking back.”

you can feel the pulsating of katsuki's heavy cock, pressed against the plush of your ass – it makes you squirm and fight the strong arms that restrain you. you turn your head, batting your eyes at the blonde as your chest heaves. a silent question is held in your longing gaze: help me?

he snorts. "what are you lookin' at me for?" when he lowers his lips to your ear, his voice is barely above a whisper. "you're just diggin' yourself deeper, sweetheart." you heave a sigh and reluctantly look back at the man in front of you.

izuku clicks his teeth, sets his mouth in a disappointed line; his usual gentle and permissive nature is nowhere to be found. you screw your eyes shut in frustration, still unwilling to accept defeat. in response, he meanly presses your wrist down, harder. you gasp as the overstimulation makes your toes curl, makes a fresh bead of sweat roll down the back of your neck. "so you listen to kacchan?"

"i-i listen to you both...!" you squeak, trailing off into another pitchy moan when izuku switches a setting on the toy, changing from pulsing to consistent vibrations.

katsuki chuckles behind you, muttering "please," under his breath in amusement.

izuku just rolls his eyes. "add lying to the list," he says, green eyes narrowed at your flushed face. when you start to protest, he sighs and turns the intensity of the vibrations up by one, making you squeal and writhe, of course to no avail. "you've really been pushing my buttons all day." it's too bad for you, he's not in a very nice mood right now. when your legs start to shake, he asks "what are we at?"

right, you were supposed to be keeping track... you're trembling all over, the churning in your gut indicating another orgasm is building. you swallow hard, intending to reply, but a shuddering gasp comes out instead.

izuku sighs, forcing your fingers open and dropping the vibrator into his waiting palm, murmuring about simple questions and simple rules. it's cruel, he's stolen the sensation too soon and ruined the pleasure that should have come. he always knows exactly when you're getting close, his timing alarmingly accurate; he knows your body and it's reactions like the back of his own hand.

you sob and whine, and one of katsuki's thumbs traces the skin of your inner thigh. he placatingly kisses a trail down your temple, unable to stop himself from licking his lips when they make contact with your wet cheek. he hums at the salty taste, kissing you again, your jaw this time; it's a small show of solidarity, acknowledging his role in earning you your punishment. he's always the one who spurs you on, goading you into doubling down on your bratty behavior, and today it blew up in both your faces.

at least he's feeling sweet on you right now; usually when izuku is teaching you a lesson, katsuki is the devil on his shoulder, but today he's in the hot seat right alongside you. however, izuku has different gripes with you both, and so his treatment is different too.

katsuki's breath feels so nice against your skin, and you grind back into him as best you can; he groans into you, pressing his forehead into the junction between your neck and shoulder as he shoves his hips forward against your ass, desperately seeking any relief. his cock is dripping pre all over you, sliding down your flesh and making his thighs all sticky. he's so big behind you, heat emanating off his skin in waves; it's overwhelming, the caramel scent of his sweat curling in your nose.

"i see we're both feeling bratty today," izuku tuts, turning off the vibrator and tossing it to the side with a sigh. "i think some of us are forgetting the rules."

he lifts on to his knees so he's towering over you both and slaps at katsuki's hands, indicating he should let go of your legs. you whimper when he does and your legs reflexively snap together, puffy sex sensitive to any sudden movements.

izuku places heavy hands on your shoulders and slowly pushes you back, down, you into katsuki and he the pillows behind him. "spread," he orders, and katsuki helps you hike your knees up and back, exposing your creamy pussy to izuku's hawkish stare. he bears down on you, moving one of his hands to katsuki's shoulder to brace himself, as he uses the other to line his cock up at your entrance, nudging his angry red tip against your clit just to tease you.

he's heavy against the heat of your sex, your slick soaking him all over, but he doesn't slip inside you yet – his movements are slow, deliberate. he teases at your slit and you gush, staring up at him with wide, dewy eyes as he leans close to your face, his curls tickling your skin and sending shivers arcing down your spine. his breath is wet in your ear when he reminds you,

"you cum when i say so."

izuku shifts the hand on katsuki's shoulder to brace against the hollow of his throat; you can feel the blonde's heart racing at your back. izuku leans over your head to give the man behind you a wet, sloppy kiss, the sound washing over you blissfully. you clench around nothing, the emptiness in your achy cunt bordering on painful. craning your neck to get a better look, you watch izuku place a loving peck against kacchan's lips before he taps them with his thumb, tugging the bottom one down slightly. taking the hint, katsuki lets his mouth fall open, and izuku lovingly spits – gifting the blonde graciously, affording him a small smile when he swallows the glob down obediently.

vermillion eyes are locked on green as izuku pulls back, letting his smile settle into a smug expression.

"and you, kacchan–"

he gives katsuki's throat a gentle squeeze as he finally, finally, finally eases his cock into your gaping hole, bottoming out in one swift maneuver; it leaves both of you gasping and keening.

izuku has his two little brats right where he wants them, bullied into submission and begging him for whatever he's willing to throw their way.

"you don't cum at all."

٠࣪⭑ a/n: yay! bkdk porn yay! as always, reblogs and comments are always appreciated! taglist :3 @shotorizawa @hachikinss @lonelyfooryouonly (to join you must be over 18, age in bio and following me!

it clicks when you're all at the beach, luxuriating in a hard-earned day off. it feels like a miracle that any schedules lined up, and even if only the three of you managed to find the time, it's enough. izuku feels so lucky, getting to spend the day with his two favorite people.

except, you're acting weird.

he's come to appreciate your blatant and shameless ogling whenever he's missing any modicum of clothing, so him being shirtless at the beach is resulting in downright lecherous behavior on your part. he sits between your knees, filtering sand through his fingers as you "apply sunscreen" to his back and practically drool on him as you run your fingers gleefully over every inch of exposed skin you can reach.

katsuki is returning to the car, retrieving the sunglasses he forgot to grab.

in his absence, you lean forward, curling your arms around izuku's neck and whispering filth in his ear; you're telling him exactly what you want to do when you get home later when your voice falters; izuku's head jerks up to see what's taken hold of your attention.

the culprit? katsuki, jogging towards the little corner of beach you've claimed. he stripped his shirt off somewhere between the car and here, and it's slung haphazardly over his shoulder; crimson eyes are hidden beneath dark shades.

two pulses quicken, two sets of eyes leering at katsuki's perfect form in fluid motion, but izuku only really notices yours, acutely aware of your heartbeat with the way you're all pressed against him.

"i– sorry, baby, what was i saying?" you ask, shaking (yes, shaking) your head to clear it.

"what?" he asks, eyes narrowing as he notices the faint blush dusting your cheeks, but you don't have time to answer because katsuki has reached you both, sparks flying from his hands as he crosses his arms over his chest in annoyance.

"all that time an' you're not done yet?" he scoffs. "this isn't a strip club, no one wants to see this shit in public." izuku rolls his eyes, used to the blonde's complaining, and you should be used to it, too... so when you let go and lean away from your boyfriend, he actually does a double take.

"whatever, katsuki." you mumble, "you're annoying."

and that's when the lightbulb above izuku's head clicks on, eyes widening as he glances between the two of you rapidly, subtly enough that neither of you seem to notice. 'you're annoying'?

he mulls over the words, turning them around and around.

...'you're annoying'...

finally, it feels like things are starting to become clearer. typically, when you tell izuku he's annoying, he has you folded in half, teasing and prodding at your patience – 'you're annoying' is what you say when you don't want to admit how hot and bothered you are.

he's deeply ashamed to admit that for the smallest, tiniest, half-second he wonders if there's something going on between his girlfriend and best friend. his face flushes royally at the thought and he clamps his hands over his cheeks to try and hide it.

katsuki notices first, raising an eyebrow and smirking. "you got a problem, deku?" he's intentionally employing his old favorite nickname, trying to make the blush darker.

izuku practically leaps for his water bottle, muttering some nonsense about overheating and drinking enough water and how actually everyone should remember to drink water, blah blah blah.

"just... gonna go refill this!" he says, already turning towards the restroom area with a drinking fountain.

"wait, love, mine is full–!" you call after him, but he waves you off, already several feet away and showing no signs of slowing.

"thanks baby, but you heard what i said, you should drink it! i'll... just, be right back! okay! bye!"

he's taking deep gulping breaths and trying not to break into a run. he just needs a second to himself, to slow his racing heartbeat and try and calm his thoughts before they spiral out of control.

the most important thing for him to remember right now is how much he trusts you and katsuki, intrinsically. he knows that neither of you would ever do a single thing that would betray him like that, so then....

why is his heart beating so fast?

it's hammering wildly in his chest, pushing him to walk faster and faster until he bursts into the public bathroom, heaving a sigh of relief when he sees it's empty. he beelines for the sink, turning it on and splashing the cold water on his face.

okay, he needs to think everything through logically.

objectively, there is something going on, although he doesn't think you're doing anything intentionally, especially because nothing between the two of you has changed, your relationship as strong as ever.

he hates even considering it, but it's pretty much impossible for you to lie to him; he can read you like a book, so it must be some subconscious feeling you aren't fully aware of yet.

alright, so what is 'it'?

you, and kacchan... you, and kacchan....?

you and kacchan.

he covers his mouth with his hand and whispers, "oh my gosh." laughs, too, and rubs his eyes with both palms like he's trying to force himself to understand.

you like katsuki. well, that isn't certain, but you're definitely attracted to him, so much so that you've clearly developed a little crush.

izuku leans against the sink, just... processing the wide range of emotions that flood him. initially, there's an old and familiar ache, jealousy twinged with something else churning in his gut. but, if he thinks about it, what is there to be jealous of? you're his, that's something that he's very sure of, so there's no need to worry about losing you or something, not that kacchan would even try and.. what, take you?

izuku groans and starts pacing, trying to snap himself out of it. maybe he's just overreacting!

but he knows, deep down, that he's on the right track. now he has to figure out the reason the blush on his face hasn't died down in the slightest, why his pulse still races.

you and kacchan.

you, and kacchan.

oh.

the final piece of the puzzle has been placed now, the bigger picture clearly visible, and he stops his pacing to catch sight of himself in the dirty mirror above the sink; eyes wide, skin ruddy, hair out of sorts from the way he's been tugging on it.

is he turned on right now?

all it takes to confirm is a glance down, and he gasps when he realizes he's rock hard, this fact somehow completely passing him by as he sorted through his thoughts.

thoughts which are now changing pace wildly, shifting to something izuku deems to be completely inappropriate, and he tries splashing some water on his face again, but it doesn't help in the slightest.

"fuck," he mutters under his breath, tugging at the waistband of his swim shorts to try and give himself a little relief, but the movement does the opposite, has him biting back a guilty moan as he really lets this sink in.

the thought of you and kacchan, together... he's seething with a different kind of jealousy now, jealousy directed towards the fantasy he himself has concocted, wanting to be... included? that, and the fact that you find katsuki attractive is turning him on more than he wants to admit to himself.

before he can stop, he's stumbling into a stall, slamming it shut and leaning against it in one fell swoop. he tugs his weeping cock out of it's confinement and palms it, a shudder passing through him at the contact.

he bites his lip when he realizes who exactly is on his mind right now, as in which two people.

"oh, fuck fuck fuck," he mumbles again, slicking his length with the ample pre that pours over his fingers.

it's almost humiliating, that his immediate reaction to the realization he and his partner both have feelings for his best friend is to furiously jerk himself off in a bathroom stall, but he's too locked in to really register the feeling, or care.

a breathy whine leaves his mouth as he increases the speed and pressure, circling his tip with his thumb. he's close, really close, surprisingly close, and the thought of you so entranced by katsuki just a moment ago has him reeling.

even more, the thought of you pressed between the two men, pretty little dynamight bracelet dangling from your wrist as two hands grasp at you from either side, the thought of pressing against you, leaning over to shove his tongue down katsuki's throat... the thought of all that touching and feeling.... izuku reaches desperately for a fistful of tissue to help prevent the mess he's about to make, pressing his forehead to the cool door of the stall and cumming, hard; trying somewhat unsuccessfully to strangle the whispered cry of your's and katsuki's names.

he just stands there for a second, breathing finally slowing a bit, blinking back to reality. he silently wipes himself off with a little more tissue, then throws it all away, tugging his waistband back up and trying to collect himself before he exits the stall.

when he'd entered the restroom, maybe five or ten minutes ago at this point, it had been empty, but it is not empty now. katsuki leans against the entrance door's frame silently, arms crossed with a smug expression written all over his face.

"was wonderin' what was takin' so long," he says simply, letting the tension in the air build and build. izuku just stares at him for a long moment, trying to analyze his stance, maybe guess at how much he had heard. clearly, he'd heard something.

but katsuki says nothing, instead choosing to saunter further into the space, eyes roaming over izuku's ruffled appearance. "feel better?" he asks.

"yes..." izuku answers slowly, cautiously. he doesn't elaborate, doesn't ask any questions; the look on katsuki's face says everything he would want to know, anyway. he carefully walks towards the door, only turning around when katsuki starts to softly call his name.

"just–" he gently cuts him off, green eyes meeting red ones imploringly, "let me talk to her first, okay?" they seem to have some sort of unspoken argument then and there, staring, holding back and straining forward at the same time.

finally, katsuki breaks first, shrugs and moves to follow izuku back to the beach, back to you. his shoulder brushes into izuku's as he passes him, and he glances back to watch the former gaze at the spot of contact with wide eyes, then look up again with a tiny, almost undetectable smirk of his own.

izuku swaps the smirk for a serene smile as he leans forward and ruffles katsuki's hair with a chuckle, much to the chagrin of the blonde.

"hah?" katsuki exclaims, finally fighting a blush of his own as izuku exits the bathroom, emerging into the sunlight.

"c'mon, kacchan," he calls. as they walk back to the sand together, he adds, "and really, not one word, okay?" his tone is lilted, a little too flowery, a little too sweet; katsuki's known him long enough to hear the very real warning underneath.

"whatever, nerd," he mutters, rolling his eyes, but the rosiness of his cheeks gives him away.

back by the water, you're growing bored as you wait for the boys to return. you've taken to tracing shapes in the damp sand, drawing little doodles of hearts and stars.

"oi, he's fine," you hear, and look up sharply, features breaking into a radiant smile when you see them returning to you. izuku runs over to scoop you in his arms and plant a messy kiss against your cheek, while katsuki hangs back, just watching. when you wave at him enthusiastically, he smiles, raising his own hand in response.

"need to talk to you about something," izuku whispers in your ear when he sets you down on your feet delicately, and you turn and look at him, head tilted as you wait for him to go on. "but, later, at home, okay?" he continues, smiling sweetly to let you know it isn't anything bad.

you nod slowly, confused but trusting him wholeheartedly. "okay...?"

"m'sick of third wheeling," katsuki groans loudly, interrupting, and you coo at him as you plop on to your towel, stretching and laying back to bathe in the sun.

"aw, kacchan, do you feel left out?" you ask, patting the towel beside you to gesture him over.

izuku coughs, loudly, and another blush starts creeping it's way up katsuki's neck.

"somethin' like that," he murmurs, coming over to sit in the spot you're indicating.

"yeah," izuku quips, sliding down next to you on the other side, sharing a quick, knowing glance with katsuki over the top of your head. "something like that."

٠࣪⭑ a/n: fun little challenge! how many times did mia use the nickname "kacchan" in this fic? (answer: so, so many) anyway, i think we’re gonna see more of these three. as always, comments and reblogs are appreciated!

freckled cheeks are a shade pinker as the man swallows quickly, mumbling a soft, "sorry, sorry..." but katsuki isn't really listening, just thinking about your joking proposal.

living here. being here. his eyes flick to you and he can't help but rake them over your figure; the tank top you're wearing is thin, and one of the straps is starting to fall down and off your shoulder. he has half a mind to reach out and tug it back up for you, to brush his hand along your collarbone and feel your warmth.

you're making a show of eating your dinner, exaggerating bites and moaning about how satisfying it is, and katsuki feels his mouth go dry. he shifts his gaze to lock on to your throat, watching the way it bobs as you swallow. he squeezes his hand into a fist to stop the tremor that arcs through his fingers as they long to stretch and taste your delicate skin.

you catch his eye, and he swears there's a twinkle in yours.

it's a moment with just the two of you, though, when he truly realizes there really is something – something he can't quite put his finger on.

it's a couple of weeks later. you just needed a ride, that's all. your appointment time was changed at the last second, and there was no way the train could get you there in time, not all the way across town. izuku was at work, so were all your other friends, and you just needed a ride.

katsuki's mildly surprised when he sees that it's you, calling him in the middle of the day. he happens to be taking a long lunch, poring over some paperwork from the day before he'd neglected to look at, (too much in favor of going home at some sort of reasonable hour).

when he picks up the phone, you sound apologetic before you even ask. "hey, i know you're probably at work right now–"

"on lunch," he interrupts, shoving the papers aside. "do you need somethin'?"

"annnyyyyy chance you're available to give me a ride? no one else is free, and i have an appointment, it was originally supposed to be in a couple hours, but–"

he rolls his eyes as you launch into a long winded explanation, fighting the smile that's trying to claw it's way onto his features. it doesn't matter if he was dead last on the list, you still think of him as someone you can ask for a favor. if it was anyone else (except maybe izuku), he would probably say no and let them figure their shit out, but instead he says, "where do i need to pick you up?"

he chuckles at the way you gasp in relief and overdo your thanks, spewing a stream of gratitude, so he gently reminds you, "i need an address if m'gonna leave." it's funny, how similar you and izuku can be.

he might speed (just a little! sort of...) on the way to your location, not wanting to leave you stranded a second longer than he has to. when you see his sleek black car pull to the side of the road, engine purring, you beam at him and wave, before clambering in to the passenger's seat.

"katsuki!" you exclaim, setting your bag gently on the floor of the car, "thank you so much, you're the best."

he grunts, keeping one hand on the steering wheel as he expertly pulls back into traffic; he's conscious of your eyes on him, watching every one of his movements carefully. "yeah, sure. it's not a problem."

"no, really," you say, tone slightly more serious, but still playful enough. "you're my hero, dynamight!"

he barks a laugh. "that's great explosion murder god dynamight, to you."

"how ever can i thank you?" you ask, lashes fluttering and tone like honey. it sends a shock through his spine, hearing those words out of your mouth, which is awful.

katsuki's grip on the wheel tightens and he avoids looking at you, instead staring hard at the road ahead. he can't completely figure out why the comment makes him so uncomfortable. his heart is racing and his hands are starting to feel all clammy, so he tries to downplay. "there's nothin' very heroic about being free and havin' a car, just... don't worry about it–" he deigns to look over at you now, stealing a secretive glance at the look on your face; eyes wide and shiny, smile sweet, almost shy. "–alright?"

you're biting the corner of your lip, looking a little uncertain, before you reach out a hand and touch him, pressing your palm to his bicep and tapping your fingers a few times before letting your arm fall. "you're funny," you say. "izuku is right, you really are kinda bashful."

"what did that damned nerd say about me?" katsuki demands, his cheeks betraying him and flushing slightly.

you chuckle to yourself and shake your head. "nothing, nothing," sneak another look at his flustered face and laugh for real. "nothing too bad, anyway," you tease.

"he's biased," katsuki grumbles. the pouty look he sports feels out of place for him, usually seen wearing a look of annoyance and superiority. it's cute.

the rest of the drive passes in relative quiet; he has the radio turned down low and occasionally you hum along to a song, or make a small anecdotal comment. it's a peaceful quiet, warm and cozy and strangely familiar. it makes it all too easy for katsuki to overthink every single thing about this entire interaction – he's hyper aware of you next to him, watching every shift and adjustment in your seat through his periphery. curses himself when he notices your stiff nipples, clearly outlined through your shirt. he has to remind himself to shift his focus back to the road, but the silhouette of your chest feels burned into his brain.

"you can adjust the air... if you're too cold." he likes it a little cooler when he drives, prone to sweating. and really, he can't complain at the current result. he swears he feels your eyes boring a hole into the side of his face again

you shake your head, "m'good. it's nice and... comfy in here. your car is so clean."

"obviously," he scoffs.

"no, just..." you ponder for a moment. "you and izuku. you guys really are similar in a lot of ways, but... you're also so different." you laugh airily; the sound tingles in his ears, makes him feel all soft. "if this was his car, it would probably be covered in energy bar wrappers and all might collectibles." katsuki thinks that likes the look on your face when you talk about his best friend. your guard is lowered, and you get all smiley and emotional. you guys really are two peas in a pod.

when you get to your destination, you walk around to his door and tap on the window. he rolls it down and props his arm on it, leaning forward to get a better look at you. "you need a ride back, too?"

"no, thanks," you say. "i'll take the train, m'gonna meet izuku after school gets out." something in katsuki's chest tightens a little at your words, but he ignores it.

"um..." you pat his shoulder awkwardly, like you're unsure what to do, before swooping down, lightning fast, and pressing a kiss into his cheek before you scurry away, waving behind you with a "thanks again!"

he doesn't pull away from the curb for a long time, definitely making him late back at the agency, but he doesn't care, doesn't even notice. his fingers trace the burning spot on his cheek where your lips touched, enthralled. you'd kissed him.

kissed him???

"fuckin'–" he sighs, pressing his forehead to the wheel in front of him. he doesn't know exactly what you're thinking, but he's not stupid; women have flirted with him plenty in his adult life, he knows what it feels like to have someone interested in you.

but you?

what business do you have, kissing him like that? he wishes you'd never done it, wishes he'd said no to picking you up and dropping you off, wishes he could erase the memory from his mind. but he can't. the memory of your lips against his skin haunts him, and he feels that phantom kiss all throughout the rest of the day, the rest of the week.

back at the agency, when his publicist gives him a little bag of dynamight charms, encouraging him to hand them out to friends or fans, he's incredulous. realistically the charms will end up on the floor of the back of his closet, and then eventually a trash can. if fans want to seek out their own merch that's fine, that's the way it should be, but he sure as hell isn't going to start handing out party favors after saving someone's ass. that's not his job, not even a little bit.

as he goes to toss the things and save himself having to do it later, he pauses with his hand over the bin. a memory is tugging at him, something faint in the back of his mind. a conversation from a few dinners ago....

hadn't you mentioned wanting a charm bracelet? it was coming back to katsuki now, you gushing about how you'd purchased some charms for yourself and had been putting off buying a chain to display them. he slips one of the trinkets from the bag and into his pocket before tossing the rest.

when he goes to yours and izuku's for dinner that sunday, his guard is up high.

it makes him snippier than usual, and quieter. he sits at the end of the table, leaned forward with his head on his arm; just watching you both gab on about everything you've been up to, tuning out the sound of your voices. he's thinking maybe he shouldn't have come tonight, trying to steady his bounding pulse when he hears your voice, curling around the syllables that form his name.

he thinks about how he wants to hear you say it again, and again and again and again and again, and a bolt of guilt strikes through him.

it's a shame, he thinks, because the sound of you saying his name might just be the prettiest thing he's ever heard, maybe tied with only one other rendition that he's gotten used to over the years and come to love, cherish even.

he's still not quite paying attention to the conversation, and izuku's hand on his arm startles him, makes him jerk it back and sit up straight. izuku is always so touchy, and every time he touches him so... casually, katsuki isn't sure how he's supposed to react. it always feels like the edges of his vision blur a little bit, and he forgets what he was doing.

"kacchan, are you feeling alright?" izuku asks gently, and katsuki nods, gruff and dismissive.

"m'fine, what were you saying?"

you have a peculiar look on your face when you explain how he picked you up that week. "i was just saying how you're a lifesaver!"

the next few moments almost feel rehearsed, and knowing the two of you they might be. you both reach across the table at the same time, each taking one of his silky soft hands into both of yours.

he might die, he might really pass out or die or throw up or something. never before has he been so irritated with his quirk, hoping the two of you don't notice how sweaty his palms have become.

"we just..." you begin, trailing a thumb over his fingers; he gulps and looks away because your eyes on him like this are going to give him palpitations. unfortunately, he can't escape the big wide eyes tonight, because izuku looks at him with an expression and posture to mirror yours, down to the way his thumb is tracing the knuckles on the back of katsuki's hand.

"we wanted to say thank you," izuku finishes.

"for... one ride?" katsuki chokes out, trying to hide how on-the-spot he feels. "in–in my car?"

"no, no no no," you giggle. "for everything."

"we know we're a handful," izuku jokes, gesturing to the way you're both still holding on to him, "it's like you're our caretaker sometimes."

"and you don't have to!" you chime in, "but, we love having you around, so we selfishly keep letting you do stuff for us."

katsuki doesn't really know what to say. there's nothing he really can say, not with the sound of blood rushing in his ears blocking out any attempts at rational thought. he shrinks back, trying to avoid the heat of two hawkish stares. his throat feels dry and scratchy when he says, "...it's... fine. i don't mind." the staring is too much, so he hastily adds, "think you two would probably die without me."

he tries to be subtle when he tugs his hands back and folds them in his lap tightly, so tightly his knuckles turn white.

"you enable us," izuku quips, turning back to his plate, and you laugh. katsuki just lets himself imagine running out the door and escaping what is turning in to a specific kind of torture.

it's not too much later when he can't take anymore, clearing his throat loudly. he gives an excuse about a headache, and feeling tired, and how he actually cares about his own wellbeing so he'd better get to bed.

he's already at his car when he hears his name called behind him, hears the door of your complex open and shut and the sound of soft footsteps chasing around the corner after him. he catches sight of the box perched on his passenger seat and sighs as he turns around to face you. you're almost out of breath when you reach him, heaving a sigh of relief.

"i caught you, thank goodness!" you say, wrapping a robe around yourself; he watches the motion with hungry eyes. "listen–"

"hold on," he cuts in. you falter, tilting your head in expectation.

"i – uh, well my publicist, i mean – you – look, you just bought some hero charms, yeah?" you narrow your eyes in suspicion and nod, so he goes on. "they made charms, dynamight ones, at the agency, and i thought – maybe you'd like them, so i saved one of 'em for you–" he reaches through his open door to grasp the small box and hands it to you.

you take it with bated breath and hands that you fight to keep still, carefully lifting the lid; inside, a pretty silver chain sits upon a satin cushion, dynamight charm already attached.

"katsuki..." you breathe, fingers ghosting over the metal. you close the box fast, like it holds a secret, and look up at him with eyes like saucers.

"it's nothin' special," he insists. "i got the charm for free, in a way, and... it's not right, giving someone somethin' like that with nothing to put it on."

you just gaze at him, and he at you.

this drags on just a moment too long, before you break the eye contact, slipping the box into the pocket of your robe. now that the tense moment has passed slightly, he can't look at you, so he trains his eyes firmly on the ground.

"izuku wanted me to check on you," you say finally, looking back up at him. "he asked me to come and make sure you're alright to drive home with a headache."

katsuki does finally look at you again then, expression soft as butter that's starting to melt. "i'm good," he says quietly.

"are you sure? you know you can always stay–" katsuki pats your head and you yelp and swat at his hands.

"i am perfectly capable of gettin' home, jeez. you and the nerd worry about me too much."

it's nice, though, really nice. he loves that you came out here all worried, just to check on him. he likes that izuku sent you, all worried about him too.

it's a little awkward, when you both say your goodbyes. it's like you know you shouldn't be outside anymore, the air turning a particularly unbearable kind of thick. when he sits in his car, he turns on the engine, but doesn't put it in drive. just cracks a window as he tries to calm down.

just like the other day, he hunches over, head pressed to the steering wheel. the pressure helps him, to think. to breathe.

everything feels... so strange. a hundred different possibilities race through his mind, and he tries to ignore them all, tries to ignore the fire in his belly when he thinks of the way you looked at him just moments ago. he sits like that, in his car, for a long time. ten, maybe twenty minutes tick by, and katsuki sits, unmoving. it's almost a meditative state he finds himself in, trying to find center, when he hears laughter chiming through an open window in your building.

he's quick to dismiss the sound, but it's... familiar, and his head jerks up sharply when he hears a deeper, equally as melodic laugh filtering into the night air, intertwining with the first. on the second floor, the wide windows of your and izuku's apartment are propped open. from where he's parked, he has a surprisingly good view into your living room, seeing a solid third of it or so before it starts to disappear from view. he makes a mental note to tell izuku about this later so he can get some better curtains, but for now...

he can just see the end of your dining room table, where it sits adjacent to the kitchen, and the hallway leading back into the apartment. but it's good enough – just lucky, that's where you happen to be sat at this very moment. you aren't facing the window, angled back towards the kitchen as you perch on the edge of the table. he can't see your legs, only the curve of your back as you laugh, the way your hands gesture as you talk. izuku must be doing something in the adjoining room, and katsuki wonder's what it is. dishes, or making tea?

the conversation you two are having isn't quite intelligible, but he can make out your tones, hear the pitches of laughter and exclamations that pair with more emphatic hand gestures.

and he just... watches. kinda feels like a little bit of a stalker, but he can't seem to make himself leave. his whole body is practically trembling, practically vibrating with restraint as he wants more than anything to just drive away, but remains completely frozen in place.

ever since he handed you that stupid box, he feels like he's losing any semblance of self-control, not that he had all that much to begin with, not when it comes to you; not since he first noticed your eyes linger.

when izuku comes into view, wedging himself between your legs as you sit, katsuki sucks in a little breath. his sleeves are rolled to his elbows, scars and freckles on display, and katsuki is stuck on the way his arms look, rugged and textured and solid; it seems your train of thought is similar, because katsuki can make out one of your hands coming up to caress the bulk of his bicep, trail down his forearm, play with the fingers of one hand.

izuku leans in to kiss you, and all the blood drains from katsuki's face and floods to somewhere else. as you're slowly reoriented on the table by strong and steady hands, shifting you to face izuku better and pulling you closer to the edge of the table, katsuki swears it's for him, swears the universe is throwing him bone to give him a better view.

because now he can really see. you're both profiled to him, and he can see the way izuku's arm is wrapped around your waist, arching your back to press you even closer as your arms come up to tangle in his hair. katsuki wonders what it would feel like, having your fingers pull and tug at the strands to bring his face closer to yours. he imagines how good it would be to smell your skin up close, to feel your body curving into his.

blame the hour, blame the warm sticky summer air, blame anything, he knows it's wrong – but he can't help the way his hand presses into his growing bulge. he has to do something, he can't let this dizzying uncomfortable feeling go on any longer. you kiss and kiss, and he slowly grinds his palm, never tearing his gaze from the window.

he really needs to get you some curtains, or a privacy screen, something. the two of you are on full display to anyone who would bother to look hard enough.

when izuku sneaks his hand underneath your shirt, katsuki can barely make out the little gasp that tumbles from your lips, but he groans. slips his hand into his waistband because he can't take it anymore.

is he... is he really doing this? something about it, the risk, the guilt, spurs him on and he hisses through his teeth when his own hand finally wraps around his aching cock, skin to skin. he imagines it's yours, imagines himself gripping and stroking at the flesh of your chest, your stomach, wrapping fingers around your throat, the way izuku does now. he's a little rough with you, forcing your knees apart further so he can press himself to your sex, smirking at the mewl it pulls from your mouth. so you like it rough?

katsuki hasn't looked down at his cock once, like seeing it with his own eyes makes what he's doing real. he just keeps his attention locked on the window.

you lean forward, kissing and licking a column down izuku's throat, and katsuki does briefly close his eyes then, pretending it's him. imagines the heat of your breath over his adam's apple, how your tongue would feel lapping at his neck. his hand doesn't stop moving, pushing him closer and closer to the release he's been craving for weeks now. he's still picturing yours, imagining how soft, how dainty it must feel compared to his own.

opening his eyes, katsuki looks back in the window and his pumping fist finally stutters to a stop, thumb and forefinger gripped tightly around the base to keep himself from spilling too soon. in the moments he missed, hiding behind closed eyelids, you've sunk to your knees on the floor in front of izuku; he's got a hand on the back of your head as you take his girthy length in your mouth, the other leaning on the table to steady himself as he helps you choke on it. if katsuki squints, he swears he can see the line of drool trailing down your chin.

when he shifts his gaze, his inhale catches in his throat and he almost chokes on air. izuku has a tight grip as you let him fuck the back of your throat. his skin is all flushed and dewy, hair mussed from your attention... and katsuki's hand jerks again, almost on it's own. he slams a hand over his mouth to stifle a guttural moan as it's torn from his windpipe.

timing his strokes with the flashes of izuku's hips, katsuki really, finally allows himself ogle the curve of his bulky arms and broad shoulders. when izuku squeezes his eyes shut tight and pulls you off of his dick, katsuki is transfixed – he's addicted to the way izuku bites his lip slightly, to the rapid rise and fall of his chest, to the gentle caress of your face. the blonde's not sure he's ever been this hard in his life.

his free hand squeezes the inside of his car door with an iron fist as he finally looks into his lap, acknowledging the sick, twisted reality of it all. what kind of a new low is this? he's sick, really and truly believes it.

still, it doesn't stop him. he slows his palming so he can keep himself on the edge, not wanting to come a second before his best friend. when izuku picks you up off the floor in a swift motion, sets you on the table with such gentleness and adoration, katsuki wonders what it would be like to be taken care of by such capable hands. he watches as he confidently slides your panties down your trembling thighs, plants a quick little kiss to your cunt before coming up to kiss a different set of lips. he whispers something into your ear that makes you laugh, and katsuki wishes he could hear it.

when izuku slides his heavy cock inside, katsuki thinks this really might be it for him. he doesn't even know where to look, eyes flashing between your two bodies as izuku fucks you into the table, your legs squeezing around his waist and eyes rolling back as his hand rests gently against your collarbone, ominous, like a warning and a reminder.

with each squeeze around his leaky, twitchy tip, katsuki grows closer and closer to painting his clean and tidy car interior white. as izuku's hips start to speed, lose their rhythm a little, so does katsuki's hand. he's so close so close but he's waiting, waiting like he needs the permission to cum.

when izuku buries his head into your neck, katsuki knows it's almost time, kneading himself harder and faster. when he sees izuku's hips falter and still as he stays lodged deep inside your folds, he finally let's himself cum with a flick of his wrist. his heart is hammering in his chest, keeping him grounded, tying him to the earth as his soul tries to leave his body. he's shaking all over, shockwaves of his orgasm lighting every nerve ending he has on fire, his vision blurring until he has to shut his eyes and just ride the wave of sensation until it finally dissipates.

he's made a mess, a big one, cum dripping all over the sleek detailing. with trembling hands, he reaches into his glove box for the pack of wipes he keeps just in case, and cleans himself up as best he can before getting as much of the car as he can see. rolls his window up so he doesn't have to see the gentle scene in your apartment: izuku's hand on your cheek as you kiss, all wrapped in each other.

katsuki gets a glimpse of it anyway, as he finally pulls out into the street, and it heaves at his heartstrings. the light emanating from the window looks so warm, contrasted with the dark and gloomy night sky. he yearns to be there, to bask in the light and just let himself be at peace for once.

he thinks about that scene the whole drive home: the three of you, safe and sound and together. intertwined.

٠࣪⭑ a/n: i am actually in love with this fic. treat her gentle alright? also guys..... did you get my plan.... 3 people.... 3 parts..... 3 perspectives..... who, i wonder, is next??? would also like to shoutout aali for being my muse and helping inspire this one. reblog and comments are always appreciated! taglist :3 @shotorizawa @hachikinss @lonelyfooryouonly (to join you must be over 18, age in bio and following me!)

or, when he’s inside and buried to the hilt, heart pounding, trying not to squeeze his eyes shut because he’s so close to cumming but he doesn’t wanna miss single second of the pretty faces you’re making…. you beg him, “k-kiss, katsuki, please, something,” but he knows if he grants your request it’ll push him right over the edge and he needs to hold on because he’s too engrossed by you, too locked in to the feeling of your messy cunt squeezing him for all he’s worth. so he grunts, caresses the side of your face before slipping a thumb past your parted lips, giving your mouth something to do as he fucks you through.

izuku is.... less sweet about it. think that he likes his fingers in your mouth because he likes how it overwhelms you. he wants to be in control of each of your five senses, wants you to consume him and be consumed in return. he likes to fill your entire field of vision, faces nearly pressed together so his eyes are the only thing you see, likes it when you nose along his skin to smell the sweat and musk and sex; he likes when you shiver at his touch, leaning in for more, likes it when he whispers praises and filthy things in your ear and he can feel you clench around him. so why shouldn't he like to watch you taste him too?

he'll slide the pads of his fingers across your lips, heart soaring and smile beaming when they fall open without any further instruction. it's nice when you're feeling all soft and pliant and needy, makes you extra submissive to his whims. he isn't so much fingering as exploring. he wants to feel the ridges of your teeth as they scrape his flesh, wants to see how far back he can go before you start to gag. he wants to see drool on your chin.

when it comes to.... other places, i think it's actually just katsuki to be honest. that is, he's more likely to use his fingers for your pleasure. he uses them to coax you to a peak, prodding and molding until you soften like warm putty in his hands. and i think he likes his hands a lot, and knowing they can pull such delicious reactions from you fills him with a sense of pride.

if you asked him which he prefers, giving you head or giving you fingers, i think it's a toss up; you're addictive to him either way, and when he's down face to face with your glistening pussy, he could die a happy man.

the thing is, when he fingers you he gets to be closer to you. i think katsuki likes to study every minuscule change in your expression as he pumps his fingers gently, likes to hear the gasp that starts in your chest and works it's way up to your head when he adds another finger, satisfied smirk plastered on his already too smug face. you don't become the very best unless you do your due diligence, and he's gotta know the results of every single action he takes. he wants his body to surround yours, wrapping an arm around your torso to hold you up when you start to lose your strength, begging you to give him just one more. so what if that's what he's said already? it felt true then too...

whereas izuku... yeah idk. i think it doesn't matter to him. it's spur of the moment, it's whatever he feels like right then.

still, i think he likes giving you his tongue more than his fingers sometimes because it allows him to use his hands for other things, like teasing and groping at your flesh, or keeping your knees pressed nice and wide.

if you're short on time, or whatever, he'll slip his fingers inside and within a stunningly brief timeframe he's cooing as you clench and spasm around him while you cum, slick arousal dripping on to his wrist – he won't relent, won't give you a moment, already asking for another, another. fingering you is almost a show of skill, like he's proving how well he knows all the little things that get you there.

when he settles his head between your legs though, he gets nice and comfortable, eats like a man starved, and adding a few fingers just adds to the experience, makes it messier. i think he eats your pussy for himself just as much as for you, if not more. he isn't coaxing orgasms out of you, he's taking them.

some food for thought: you're straddling katsuki's lap, facing him with your knees extended so he can play with your pretty pussy. your stance is forced wide by his body beneath you. izuku is wrapped around him from behind, one of his hands stroking the blonde's length with a torturously slow pace as the other hand grips your cheeks and keeps you upright and forward facing.

"stay still," he murmurs, and you know he's talking to both of you by the way katsuki's breathing grows heavier but his body stills, save for the way his fingers are still knuckle deep inside your warmth, stroking lovingly against your walls. izuku has his head propped on katsuki's shoulder so he can watch – all three of your faces are so close, sharing the same air and swallowing each other's gasps.

when he kisses a line up katsuki's neck and you feel him shudder, it makes you crave a kiss, too. you lean forward, all needy and selfish, and izuku slides two fingers in your mouth to stop you and tide you over.

"our baby sure is greedy, isn't she kacchan?"

katsuki's eyes are low as they slide across your face, which is adorned with an almost comically lewd expression, tears slipping from the corners of your eyes as you lap at izuku's fingers. "doesn't know how to wait her turn."

"no, she doesn't," izuku hums in agreement, sliding his fingers even deeper, and they both chuckle when you moan pathetically.

"fuck, she's gushin' all over me," katsuki pants, pressing his thumb to your clit because he knows it's going to make you cry out. when it does, he glances to izuku and smirks before looking back at you. "you like our fingers in both your holes, huh?"

"of course she does," izuku quips, "such a messy, needy girl." his eyes are locked on your face now; your cheeks burn at their comments. you go to lean back again, but izuku says, "hold her, please."

katsuki's hand comes up to palm the back of your head, keeping you in place so izuku can watch you gurgle around his impossibly thick fingers.

"bein' so good and taking us so well," katsuki praises. his words send a shiver down your spine and make you clench around him, your mind blank with the heightened pleasure and attention you feel.

izuku locks eyes with you and you can see, he has his stern face on so he's about to give an instruction. "you like kacchan's fingers?" he asks, and you do your best to nod. the coil in your gut is taught, ready to snap, but you know what happens when you cum without permission.

he smiles, deciding to be generous and give you what you want, then says, "alright baby, prove it. cum all over them for us."
