“for fucks sake, kirishima, that is not a fuckin’ guard dog.”

only katsuki bakugou could be this miserable in an adoption centre for adorable hybrids— kittens, bunnies, mice and puppies alike. the redhead gives the employee standing nearby an apologetic mix between a smile and a grimace, the poor thing shaking in their boots at the proximity of the dynamight.

“katsuki, don’t yell. you’ll scare the ‘lil thing,” he pouts, sticking his fingers through the wire bars on the cage— coaxing the little hybrid inside closer. “and i thought you said german shepherds made great guards!” kirishima wiggles his digits again, pursing his lips to make those kissy sounds that are usually used to call to cats and crouches down to the height of the enclosure.

bakugou smacks him upside the head but takes a stance beside his rioting hero friend before signing dejectedly. “wrong sound idiot, you’re meant to whistle,” the two strong, and surely intimidating men spare a glance at the cowering hybrid as katsuki whistles in an attempt to gain some trust. “and they usually do, but this one looks like they might shit themselves if someone looks at them funny. not a guard dog.”

“but bakugou—“

“i hate to interrupt, mister riot. mister dynamight.” the employee from earlier steps in, steeling her nerves as she gestures to the cage the puppy hybrid is in. “but if this one doesn’t get adopted soon, i’m afraid they’re going to be put down. we don’t have the space for slightly quieter and apprehensive hybrids like them, no one really wants them if they’re not overly friendly or energetic and…if they do it’s usually for the like…”

“hybrid farms,” bakugou finishes for the kid, his voice thick with disgust. “just shut one of those down the other day. awful fuckin’ places.”

kirishima pouts again, peering into your cage— noting the gloss in your big pretty eyes and how you shrink in on yourself, tail pinned to the ground without the happy swish to it that other puppy hybrids in the centre have. “so…” he can’t imagine what you’ve been through, what you’ve seen to have ended up here. “if they don’t get adopted today, they’ll be put down? isn’t there any other way? that hardly seems fair.”

“to us it’s a little more humane than ending up at a hybrid farm or those indecent love hotels exclusively for sex with hybrids…” the employee trails off again, nervously fidgeting with their fingers. in the distance, a bell chimes with the notification of more customers— a mother and her child, probably looking to adopt one of the younger, nosier hybrids for their family. “if you’ll excuse me…”

“i’ll take ‘em!” red riot blurts without even thinking, the employee not having taken two steps away from him and his angry blonde friend who looks at him like he’s gone bat-shit crazy. “this is their only chance, right? i have to do something, they don’t deserve to go out like this.” the blonde closes his mouth, holding his protests thoughtfully.

he’s right. kirishima is right, his kind soul always is. “ai’ght, fine. but don’t expect me to train that thing, they ain’t nowhere near close t’bein’ a guard dog.” bakugou grunts, folding his arms across his broad chest with a faux look of dismay— not admitting how impressed he is with eijirou.

eijirou kirishima has a heart of gold, he’s always been like that— putting others before himself because he believes in them. he takes in strays, builds up their strength and their confidence, letting them know that he’ll always be the sturdy figure they can fall back on in times of need. katsuki was one of those strays, an unwanted dog just like you. he’d bared his fangs to the sweet redhead in fear of letting in someone that would hurt him, but as it turns out, becoming friends with someone as selfless as kirishima was just what katsuki needed.

the employee sighs, shoulders sagging with relief as they glance between the two pro heroes. “should i be getting the adoption papers then?”

with an enthusiastic nod, red riot peers back at you with affectionate eyes and a smile you can trust— one that only widens when you bump your head against his fingers over the bars of your pen and let the tips of them just brush your lush puppy dog ears. “yes please,” he says warmly, his gaze never leaving you. “don’t you worry about a thing little one, it’s you and me now, got it?”

and for the first time in forever, your tail wags happily, and you don’t feel worried at all.

being adopted by eijirou kirishima most probably saved your life.

he’d been eager to get you out of that shelter, with the promise of a better life written against his lips and lost under his tongue as he babbled about your new home and how excited he was to have a puppy hybrid of his own. a timid, sweet faced and jumpy german-shepherd hybrid nothing like their breed— with big eyes, a set of pointed and twitchy puppy dog ears and a tail that stays pinned to the ground with nervousness. there’s a lot for him to undo, a lot of trust to build up.

kirishima was patient when introducing you to his home that only big time pro hero money could buy— he let you sniff out the place, scenting areas that made you feel safe even having his comforting, large presence right beside you was enough to make your ears perk up and heightened senses go wild. he let you pick out the biggest spare room in the house and had even felt sad for you when you stated that you’d never had your own before.

“with me, i’ll make sure you have everything you want ‘n more, kay pup? things will never go back to the way they were for you.” the red head swore to you, crossing his heart — that was the first time you’d ever felt love like that.

the two of you quickly fall into an easy routine; kirishima would leave for work in the mornings after making sure he’d set out the perfect meal a growing pup, like you, would need— using all sorts of kibble that his explosive friend katsuki had recommended. occasionally he’d spoil you with pieces of turkey bacon that he knew you weren’t allowed to have, but what was the harm in spoiling someone who hadn’t experienced luxury before? plus he liked the way your German shepherd tail would wag and your pupils would dilate at the sight of the meaty meal.

eijirou made sure you had all the toys possible to play with while he was away for work— you didn’t like sitters and nearly chewed out the last one katsuki had recommended for a nervous puppy such as yourself. you didn’t like her scent and how it had gotten all over your owner. you preferred to be alone, surrounded by the pinewood and musky husk the redhead would leave behind. and, by the time he came home from being red riot, you’d be sitting right by the door with big bambi eyes to welcome him home, the little bell on your store-bought collar jingling as you rush to meet kirishima at eight pm sharp each day.

though you’re pampered with treats and pretty things and ear scratches 24/7– kirishima does have you trained by that awful bakugou. you’re by no means a guard dog, despite what your hybrid breed might indicate— but you’re disciplined with house rules and how to sit and act properly. bakugou is mean and he snarls at you from time to time, but the praise and kisses you get from your darling and sweet red haired owner make the training completely worth it.

nowadays, katsuki doesn’t even question when you scamper onto the couch or perch yourself on eijirou’s lap whenever they have their boys nights to watch the hero rankings live. “pampered fuckin’ pooch,” is all he grunts from over his can of beer.

“hey,” eijirou will huff, his hands on the fat of your waist or twirling through your fluffy brown and black tail. “don’t be mean, katsuki. they don’t know any better.”

even with all that house training— you still sneak into his bed when being on your own gets too much. his warmth calms you, and eijirou doesn’t seem to mind the brush of your thick and soft tail against his thighs in the morning. “pup, you’re not s’pposed to be on the bed,” he’d tried to scold you the first time it happened, he really did, but your ears lay flat against your skull and you gave him those eyes and kirishima was quick to dive in next to you— asking you what was wrong. “nightmares huh? of the pound? well, those can’t be very nice. maybe you should share a bed with me tonight. one night won’t hurt, will it?”

except one night, becomes every single night.

repeatedly, each night, eijirou scoops you up into his flexing, toned arms and carries you to his room instead of your own— tucks you under his weighted duvets not yours, and swamps you with his body heat. he runs like a furnace during the later hours, not that you mind, it’s nice to be close to him. to feel adored like that.

yourself and kirishima are touchier than most hybrid-owner pairs, you’ve noticed. bakugou thinks it’s because you have a clingy-attachment style, the red head because you’ve been deprived of the affection that most pups deserve. he goes beyond headpats and chin scratches, and the ones that itch right behind your floppy fluffy ears. kirishima keeps a hand on the slope of your waist when he takes you for walks on sunny days, he holds your hand instead of your leash most of the time and his lips linger against your forehead a little longer than normal for a hybrid that’s just a housepet.

you think it’s normal at least, you’ve never been cared for like this and having eijirou’s attention some, if not all, of the time feels like a dream come true. you know that he loves you when actions of endearment become more passionate— when innocent cheek kisses become sloppier lip-locks and when hugs turn into desperate attempts to grab at your flesh, also when your heat cycles become less about finding a mate and more about begging kirishima to ravage you against the nearest surface, soothing the instinctual ache in your bones and lower tummy.

he loved you, and you loved him— and you knew that you owed it all to kirishima for the better life he gave you. taking a chance on a shy little puppy hybrid at risk of being put down.

taking a chance on you.

“angel, ‘m home!”

the rustling of brown paper bags, heavy foot-steps and keys jingling in the front door make your puppy dog ears twitch and you perk up from your place deeper in the house at the sound of kirishima coming home from a long day’s work. you scramble up to meet him half-way into the kitchen, tail swishing a mile a minute behind you, nose wriggling in anticipation. “e-eji!” you breathe, fingers itching to reach out and touch him. “you’re back!”

you’re so cute, so loyal that it warms the pro hero right down to his core. kirishima nods once, giving you the go ahead to latch onto him since you’d waited so patiently and lets out a small chuckle as you tuck yourself into his side. “i always come back, don’t i?” setting the bags on the marble island, he frees up a hand to brush over your head softly, using a knuckle to rub behind your ear. “have you been good, baby?” moving to cup your cheeks next, he presses a gentle smooch to the tip of your nose. “‘course you have, you’re always good f’me…but, i gotta know— did ya miss me?”

“i always miss you,” you say a little too quickly, nuzzling into the palm of red riot’s large hand, tail wagging even faster. “can i…can i have a kiss, eiji? please.”

for a moment, a primal look flashes through the hero’s eyes before being replaced with something softer, something that mirrors the smile he gives you. “only ‘cause you asked so nicely, baby,” he says playfully, sliding his hands from your face down to your waist and tugging you nice and close, your hips flush against one another. “c’mere puppy, gimme some sugar, hm?” your body can’t help but bristle, keening into kirishima’s touch as he subtly lowers his voice and guides you into following his command.

you stand on your tiptoes without even realising it, tilting your head upwards as kirishima coaxes your mouth open with his mellow moving tongue—sighing sweetly against your lips until he’s captured them properly in a slow kiss, not giving you too much but pouring enough words into it to let you know how much he cares for you. he pulls away so things don’t too heated, but still keeps his hands on you before you can whine in protest.

“what’s that?” you ask softly, cocking your head to the side when you notice the bags behind him.

“oh those? well,” kirishima swoops down to your height, nipping your nose with pointed teeth— only serving to make it scrunch up adorably. “i heard it was a certain pup’s birthday today…and it also happens to be the one year anniversary of their adoption. so i got ‘em a lil’ somethin’ to celebrate.”

he lives for the way you smile, almost dies at how your eyes sparkle. “c-can i open it eji?”

“not all of it, pumpkin,” eijirou briefly lets you go and you really do whimper this time, knowing better than to claw at him to stay when you know he’ll be right back. the burly redhead turns to grab a perfectly wrapped package from within the brown paper bag and passes it to you with an eager grin. “go put this on f’me, will you baby? then meet me in the living room once you’re done, for the rest of your present, kay?”

“okay! i’ll be quick!” you practically squeal, vibrating in your place.

“good pup, i’ll be waitin’,” he turns you around with a grip that's barely there, handling you as if you’ll break with too much force and patting you on the bum softly as you go.

by the time you return to the living room, it’s been completely transformed.

the lighting is dimmed, a ruby glow filtering through and the soft hum of your favourite song reverberates against the walls and high ceilings. kirishima seems to be fixing a box on the coffee table by the couch before he notices you, a slick and sexy grin tugging at the corners of his lips as you approach him. “there’s my pretty puppy,” he rasps lowly, sending a shiver from the tips of your ears right down to your toes. “god, i think i made the right choice pickin’ that cute lil’ number out for ya, looks so good on you, hun.”

heat pulses under your skin like buzzing kinetic energy, making you tuck the swell of your cheek into your shoulder bashfully, fluffy ears flattening against your skull. “you think so?” said number is a darling little babydoll dress, made of black silk and red lace lace accents that tickle the backs of your thighs with hearts embroidered at the chest.

“it looks perfect on you baby, you’re breathtakin’,” kirishima tells you earnestly, holding his hand out for you to hold— which you take shyly. “c’mere, twirl f’me? wanna see all of you. show off for me, cutie.” every single one of his compliments has your tail swaying from side to side and blood rushing to your brain, making you dizzier than the cute little spins you do for him while the pro hero sinks into the couch to watch you.

he leans back, thighs spreading wide— and you have to fight the urge to drop your gaze between them. “that’s it pretty thing, my puppy’s such a fuckin’ stunner.” kirishima swallows thickly, ruby glossed eyes darkening with desire. “come t’daddy pup, wanna give you your other gift.”

you quickly shift to stand between his spread legs, quivering like you’re cold has large and rough hands swallow your waist and bunch your night dress up at your hips. he presses sloppy kisses to the softness of your tummy over the material.

“sit.” he commands simply, tugging on your hips to pull you down with him

“yes daddy,” your breathing is ragged as you sink into kirishima’s lap, thighs apart so that you can straddle him properly. you wonder if he can hear your heart racing from its place in your chest— your heightened hybrid senses can already pick up on his, kirishima’s pulse sky-rocketing now that you’re on top of him. “c-can i have my gift now?”

his calloused hand pushes the black silk up and over the curve of your ass, red riot digging into the fat of it to rock you back and forth over is hardening girth. “r’member your manners, puppy. yer s’pposed to ask daddy nicely.” nonetheless, he relents and snatches up the box on the coffee table— handing it to you to unravel. “open it up, baby.”

excitedly, you tear through the daintily wrapped package, revealing a red patent leather collar—decorated with red and black bows, and a heart shaped tag with the letters ‘EK’ inscribed into it. collaring was a big deal in the hybrid community, it meant a permanent mark, belonging to someone, being in love.

“let me put it on you,” eijirou simpers, readily slipping the leather around your neck and sliding two fingers underneath it to tug your lips up to his. “i love you, pup.” he confesses, licking into your mouth hungrily and grinding up into your dripping heat.

it’s embarrassing how wet you’ve gotten and so fast, dumbly following him to the forest fire of lust, sucking on his tongue like a parched puppy lapping at the first drink it can get. hybrids slick up faster when aroused and kirishima turns you on like no other— somehow finding your panty covered clit between your salacious bump and grind.

slumping against his beefy chest, your nails dig deep into his shoulders and whistle tone dog squeaks bubble up on the swell of your lips each time eijirou swipes the pad of his thumb over your swelling pleasures nub, encouraging your juices to gush over his hard on—glueing you both together by strings your arousal.

“i love you too…p-please e-eiji!” the air in the room feels heavier, tainted with the lust that clouds your logical thought. in fact, you can’t even think right with the way your owner toys with you. he drools against your puppy tongue, curses into your heated mouth all while you’re riding his fingers like your life depends on it, kirishima pinching at your sticky clit just to hear more of your needy whines. “p-please daddy,”

the hand that once sat lightly against your neck now trails over each dip and curve of your body, barely brushing over your nipples or digging into the meat of your ass and thighs. “you look so fuckin’ good in the things i buy you, hun, drive me fuckin’ insane,” kirishima fights back a moan, cock twitching against your ass, desperate to be inside of you. “so beautiful in that lil’ dress, with my name around your neck. fuck… ‘m so lucky. my pup, daddy’s sexy fuckin’ puppy.” he rambles and praises you all at once, giving you whiplash, making you clench and ooze sweetly around nothing.

you’re sure that the redhead is almost as brainless and as fucked out as you are just from dry humping his darling little pup… but through his own grunts and groans, hips wildly bucking up to meet yours— kirishima still manages to dominate you, make you feel like you don’t even have to think around him. “you want me, pup, is that it? want me to fuck you?” he hums huskily against the shell of your ear, pinging your collar against your neck when you nod your head yes wordlessly. “gotta—fuck�� gotta use your words f’daddy, c’mon now, you know that.”

“y-yes daddy, want you. badly.” you slur, and suddenly, your world tilts on its axis. your back hits the sofa with a bounce and you're pinned against it by the weight of your owner above you, your knees being pushed into your shoulders.

“a-always such a good…obedient lil thing f’me,” eijirou groans at the sight of you beneath him. “so perfect, ‘m so lucky t’have such a beautiful puppy all to myself, shit!” your silk baby doll gathers at your hips, soaked panties tucked to the side and your glistening, pulsing mound on display like an attraction made just for him. he wastes no time in yanking down his sweats and boxers in one go— revealing his bright red and angry dick, covered in a thick layer of gooey white precum. all for you. kirishima slaps the length of himself against your slit once, twice before his forehead falls against yours.

“p-put it in eiji, c-can’t wait daddy…”

even though your cute little sex makes him a wreck, eijirou still manages to hold control over you— teasing you as he forces his fat tip past your tiny, creamy entrance. “so impatient, cutie, i should make you say please… but fuck, i need you so bad right now. might not last long…”

the pair of you let out strained moans as kirishima pushes in and he reaches the hilt—your sweaty bodies flush against one another, both of you covered in layers of each other’s arousal. your pussy flutters at being filled up so fast, clinging onto the pretty blue veins that spiral around his chubby, swollen cock— a low whine rumbles in your chest as the redhead sets a rough stream to his thrusts, milky cockhead brushing against each pulse point on your sensitive walls.

it’s almost like you’re being knotted, squelching as kirishima tries to pull out of your snug sex that grips him selfishly. all the while, he pounds you to hell and back. you're so full, you’re a slobbering mess already teetering on the edge of insanity. red riot leans over you, washboard abs pressed against the backs of your thighs to force you down into the creaky couch— each time he withdraws from your messy and wet walls, your ears fall back and your tail thumps hard against the cushions, coated in your viscous nectar.

“fuck, this puppycunt sounds so dirty, gorgeous…feels like fuckin’ heaven,” he whispers to you, words damp on your cupid’s bow. “my perfect puppy, a dumb lil’doggy on my cock…s’such a fuckin’ dream.” your brain empties, becomes a void that’s filled with only eijirou kirishima and the way he fucks you deep, hits every spot, touches your body like a man worshipping a higher power. “‘m so lucky baby, really am.”

your collar jingles, the pendant with his name on it bouncing every time kirishima’s cock bullies its way into your gooey insides until they give into him. you’re the lucky one, you think— lucky to be loved like this, to have been rescued from the pound and pinned down on a dick that aches to be inside you, wrapping around his pulsing length to the point where you’re practically milking him already.

“d-daddy!” you hiccup, big fat tears clumping in your lashes, your face a beautiful mess to the man above you. “i can’t…”

the pro hero reaches down between your bodies, close to cumming just from listening to you howl over the sounds of skin slapping on skin, and tugs at your soft slick tail—stroking it until your pussy quivers and gushes around him, painting your babydoll dress and his half rolled down sweats with a fresh wave of your essence. every time he pets the fluffy appendage, you get wetter and wetter, tighter and tighter and your moans loud enough to wake the neighbours.

heavy hips rock into you, even heavier balls clap creamily against your fleshy ass and kirishima lets his head drop to your neck—biting and sucking possessively at exposed skin just above where your collar lies. “yes you fuckin’ can, your daddy’s good pup right?” he slurs hungrily, writing his claim against your throat. “when you get close, hold it f’daddy, be obedient ‘n you’ll get your reward.”

you feel like everything’s on fire, every nerve ending in your body buzzing with anticipation— the knot in your stomach seconds away from unwinding. “b-but daddy—!”

“hold it.” eijirou warns sternly, though his breath stutters— every instinct that he has threatening to breed you up full with a load of his hot cum. “h-hold it, hon,” you sob at the pain and pleasure of holding off, thighs twitching, tail hitting the couch hard and puppy ears flopping over your face. you’re so adorable like this, jolting up the piece of furniture as the redhead languidly canters into you. he finally breaks when you let out a weak cry of his name, his first spurts of cum pouring into you. “f-fuck, let go for me puppy, make a mess on daddy’s cock—shit, thats it. so good, all over me, wanna see you cummin’ with me…”

white hot ropes of seed paint your insides just as your eyes roll back into your skull. he feels so warm, coating your insides with a layer of his cum as if to claim you from the inside out. there’s so much of it that oozes out of your entrance thickly, like a running tap of honey that ruins your pussy lips with opaque white—triggering your own orgasm. kirishima holds you close, whispers sweet nothings into your ear as your release crashes over you, rocking your world while your juices splatter out against his pelvis and all over your cute little gown in clear streams.

“happy birthday, beautiful,” the redhead mumbles to you sweetly, kissing his initials on your pendant and right up to your lips. “i love you.”

“t-thank you eiji,” you whisper back— a sleepy, full and content puppy. “i love you too.”
