"keep your mouth shut and let the doctor do whatever he needs to do, don't cause any trouble" his mother had said when she dropped him off at the clinic before promptly driving away and letting him fend for himself. https://twitter.com/katutsukushii/status/1356394418631245824
not that he minded, he much preferred to be alone in this godforsaken place than to have his mom looking over his shoulder and making snappy comments about his behaviour while someone looked at his newly developed cunt.
but now that he was sat in the waiting room, fiddling with his fingers as he waited for his name to be called, he almost wished she was there, just to tell him what to expect.
even more so, he wished he'd done some research the second he'd presented - it had been a few days since the torturous two weeks of presentation had finished, and he was yet to google information about male omega's and the examination that occurred after their vaginas developed.
not that he could do so even if he wanted to, his mom held a firm grip on the internet and what he looked at, he was certain looking for information about his cunt wouldn't have ended well.

even the slightest hint at such sinful study would've resulted in curses and punishment.
perhaps he should've broken the rules, just this once. but he hadn't. and now here he was, completely and utterly clueless about what he was getting into.

it was stupid, a cowardly move that normally wouldn't have been done in any other part of his life - but this was different.
it was /dirty/.

his mother had always taught him so - omegan sexuality wasn't to be discussed in society, it was something kept private for them and their alpha. mitsuki held that belief closely to heart, not only for omega's, but every other subgender too.
purity and innocence - the two traits katsuki was supposed to have regardless of his filthy mouth.

and so anything below the waist was not discussed. or touched, for that matter.

not that katsuki ever wanted to indulge in such activities - why would he? it would do nothing.
he knew the purpose of his vagina - breeding and keeping his alpha happy, he didn't need to know anything other than that.

there was no need for /touching/ of those parts.
but now he was sitting in front of the room in which the doctor would do exactly that - touch and probe and make him feel as strange as those passing touches did whenever he washed his body in the shower.
"bakugou katsuki."

katsuki looked up - red met yellow. it was the most noticeable thing about her, the colour of her catlike eyes, but even more glaring was the wide grin she wore on her face, pointy teeth digging into her lip as she bounced on the balls of her feet.
he grimaced at the sight, the nurse seemed far too preppy for what the situation was.

no one should be that excited to take him into a goddamn exam. but there she was, smiling and waving him over until he groaned and stood from the seat.
within seconds, he was in the office where the nurse - toga, he thought her name was - directed him to the small bathroom connected to the room and handed him a plastic cup.

while there, he blushed and filled the cup with urine.

ridiculous. this was ridiculous.
the nurse giggled when she saw his flushed cheeks as he handed her the cup.

but she remained professional enough to take a blood sample - only, the moment she had done so, it seemed as if those yellow eyes glimmered with something akin to joy.

katsuki ignored it.

whatever.
after taking his weight and height, she handed him a hospital gown and instructed him to change into it before the doctor came in.

she left the room, and katsuki was left all alone to... to take his clothes off.

right.

it was fine.
this was a professional environment and there was nothing he should be ashamed of.

but as each article of clothing was removed and folded up on a chair nearby, his shame grew.

he wasn't meant to do such things, get naked and spread his legs - regardless of the situation.
it was necessary, that much he knew, but the whispers of how he should hide away and not reveal his private parts were louder than the knowledge of how much he needed this.

before he could change his mind and run out the room, the door clicked open.
luckily, he was already wearing the gown, sat on the edge of the examination table as he watched the doctor walk in.
an- oh.

/oh/.

he was expecting someone much older, more seasoned and established in the field.

not... /him/.
this man was clearly new - what with his round eyes and youthful appearance, there was no way he was over the age of 27.

but he exuded confidence and power and that was all that mattered.

despite his young age, katsuki knew he was in good hands. competent hands.
the man's green eyes trailed over his form, from his toes still covered by his knee-high socks to the ends of his blond hair. it was unnerving, the way his gaze seemed to make even the scanty garment covering him feel as if it was nonexistent.

katsuki squirmed in the seat.
"hi, bakugou, i'm midoriya izuku, i'll be doing your exam today."

the words were accompanied by a refreshing scent, his tense muscles loosening at the smell without his permission - it was as if the simple inhale of fresh rain and mint caused his body to melt.
his omega whined.

such a strong alpha. strong and capable of taking care of him. /breeding/ him and giving him good pups.

shit.
crimson spread across his delicate features, skin burning to the tips of his ears as he realized the sins of which he was thinking.
when he glanced up at the doctor, he was still looking at him - leering, dissecting as if he was making plans katsuki was unaware of. there was a playful smile curling up on his thin lips, a devious smirk hiding the secrets which he was thinking of.
katsuki swung his feet, hands curling at the edge of his gown.

luckily, the man spoke nothing of his nervous behaviour, and instead, he focused on the technicalities - and so katsuki quickly yet confidently answered questions of his and his family's history.
"normally, when it comes to those who were born with vaginas, i would ask about their menstrual cycles, but in your case, that won't happen until after your heat, so we'll talk about it then when you come back, okay, pup?"
a knot formed in his tummy, a feeling he felt during those rare moments in the shower, when his touches lingered and the warm water flowed down his back.

just like then, he quickly snapped himself out of it, even if the pet name still made him blush.
“okay, now, why don’t you lay back, and put your legs up on these stirrups, right here.”

with shaky movements, katsuki did as he was told.
his mother’s words repeated in his head - “don’t cause any trouble, just do as you’re told, it’s fine.”

but his mother had also told him never to show his privates to anyone, except for his alpha.
when he was finally on his back, he froze, cheeks growing different shades of carmine and knees firmly pressed together to hide what was most sacred to him.

even the calming scent of the alpha did nothing to make him relax.
suddenly, firm, strong, /large/ hands were placed upon his bare knees, thumbs rubbing comforting circles into the skin as katsuki’s eyelashes fluttered and he set his gaze upon the man standing on the edge of the table.
the smile that was on midoriya-san’s face earlier seemed to have softened, the edges of it not quite as intimidating as they once were - almost as if he sensed katsuki’s anxiety.
the thought almost made him smile, his blush spreading all the way to his chest at the idea that this kind man was trying to keep him calm.

“i know you’re nervous, pup, but you’ll be alright. i’ll tell you what i do before i do it so that i don’t surprise you, okay?”
katsuki nodded.

“i-i just. i’ve never, uhm, never done this before.”

the doctor chuckled, fingertips dipping between his knees and causing him to spread them the tiniest bit.
“i know, you’ve just presented - this is your first exam.”

“no, i, uh, i’ve never been touched d-down there, s-so i'm worried it'll, y'know, hurt, or whatever.”

the grip around his knees tightened.
midoriya-san coughed, sounding choked up as his gaze trailed down, over the shoulder which had been revealed when the gown slipped down, over his collarbone and the delicate dip on his chest.
the doctor looked back up - it seemed as if his pupils were covering the expanse of his irises. weird.

“surely you’ve touched yourself, though? masturbated?”

katsuki tilted his head to the side.

huh?

“no, of course not. why would i? and what the hell is that?”
the look on midoriya-san's face had him squirming - did... did he do something wrong? why did he look like that? eyebrows pinched and breathing coming out heavy as if he was trying to hold his composure.

shit. he fucked up.
katsuki corrected himself, voice shaky and nervous as his legs tensed once again, "i-i mean, i do w-when i shower an-and wash and stuff, obviously, so-"
"no, no, don't worry, bakugou. you're alright. don't worry about it." the doctor's smile was back, pearly white teeth on display as his eyes crinkled and a dimple showed on one of his cheeks.

even then, katsuki swore he could feel a slight tremor in his hands.
"and it won't hurt, i'll be gentle with you. i'd never hurt you. alright?"

katsuki flushed, thighs rubbing together until he finally relaxed.

it was okay.

midoriya-san would take care of him.

he nodded.
"now, lets get started, shall we?"

right.

let's get this shit over with.
Pick which you'd prefer in the next update. :D
- TBC -

I'll keep going tomorrow around the same time! Will probably do more polls to let you choose what /exactly/ you want Deku to do :D https://ko-fi.com/jayus 
the sheer amount of luck izuku apparently had did not escape him - he supposed this was simply the universe paying him back for all of those years he'd spent miserable when he was a child, filled with loneliness and hopeless dreams of having a mate.
he just never expected said payment to come in the form of a pretty, blond omega with a scent that seemed to reveal all of his secrets no matter how hard he tried to hide them.
"you're gonna like this one," toga had said with a wink before he entered the room, and he had to admit, she was right.
the moment he had seen him, he knew he wouldn't be able to resist - he simply had to place his hands on that porcelain skin, mark him and cover him in bruises and his scent, touch those pretty lips and watch his crimson eyes widen and fill with tears of pleasure.
it seemed as if the tiny omega felt the same way, since his scent spiked with clear arousal the moment a pet name accidentally spilt past izuku's lips.

irresistible.
but then the boy had said he'd never even touched himself and izuku knew holding back was not an option - it was already difficult to stop himself from bending him over and knotting him as it was.

after all, such a pure, uncorrupted being was almost never seen nowadays.
he simply had to ruin him, destroy him for any other alpha that will ever dare to touch him in the future - no matter what, katsuki will always remember the way he made him feel, the first time he came, the first time he felt pleasure.

he would remember izuku.
and so his grip tightened on his knees, thumbs stroking over the soft skin before he moved, slid his palms over the tensing muscles of his calves, and finally grabbed his ankles, fingers overlapping and breath hitching at the sight of katsuki’s flushed face.
embarrassment seemed to seize katsuki's form, body trembling and goosebumps covering his skin as he looked off to the side - yet he remained unaware of the inappropriate touch that was bestowed upon him.

so cute.
izuku moved his legs, placing them onto the stirrups and leaving them spread apart. a gasp escaped the omega, scent twinged with anxiety as he pushed his gown over his privates.

izuku tutted, grabbing his hands and placing them to the sides.

that won’t do. that won’t do at all.
luckily, he had a solution - even if he hadn’t, he would’ve come up with a way to get in between this omega’s legs.

it didn’t particularly matter if he struggled to cover up or not.
he almost wanted to call toga in just to thank her for the instalment to the exam table she had thought of.

instead, he simply smiled as he stroked over katsuki’s wrists.
“now, i can tell you’re not going to stay still, so i’m going to have to restrain you, okay? this is for your own safety, puppy.” he spoke softly, making sure he sounded concerned and yet reassuring all at once.
red flashed with fear, eyes widening for a moment as his lips thinned out. but the boy did nothing to complain of the strange request, instead, he nodded.

shit. so fucking good already. so obedient.
with haste movements, izuku pulled the leather straps from beneath the table, strapping them over katsuki's wrists, careful not to restrict his blood flow.
the moment he was done, he moved back, standing between katsuki’s spread out legs, gown slowly falling down his thighs, as if it were teasing him with what was hiding beneath it.

quickly, he moved to his cabinets and placed his toys onto the instrument table.
finally, izuku moved back to his omega and dragged the stool closer to the table. as he sat down, his gaze landed upon the treasure which katsuki seemed adamant at covering up.
fuck.

he was glad he had such good control of his scent, he was sure had it not been so he would’ve scared the omega off immediately.
because right there before him was the prettiest little cunt he’d ever seen, right above it, a pink little uncut cock - not that it mattered, katsuki wouldn’t be receiving pleasure from that part of himself. good omega’s never did.
the skin surrounding his privates was clean-shaven, most likely waxed since many oldfashioned families did so with their omega’s - the poor little things had to make their pussies clean and smooth and ready for their alpha’s.
the lack of hair revealed every inch of him - the rosy, plump lips, the clit barely peeking through from between them, and as izuku pressed his thumbs over his lips, spreading them apart, the twitching, tight hole.
distantly, he heard katsuki squeak at the abrupt contact, but he didn’t care.

he was far too busy grabbing the gloves from the side, snapping them on and revelling at the flinch of katsuki’s body when the latex slapped against his wrists.
“i’m going to touch you now, alright?”

when he glanced up, he saw katsuki nod.
gently, he trailed his fingertips over his lips, watching katsuki shiver at the light touch, and without looking away from his face, he pushed his thumb between his folds, pressing down onto his clit and moving it in circles.
the pressure had the desired effect - a surprised squeal that had izuku chuckling, and a rough pull on the restraints.

sweet thing probably wanted to hide, cover where he was touching him, making him feel something he’d never felt before.
when his eyes set upon his cock, he saw it twitch, fill up and grow against katsuki’s toned stomach as the omega’s hips moved upwards.

cute.

with his other hand, he pulled his lips apart once again, and he watched as slick dripped from his hole.
the scent was stronger here, more potent, pure and unabashed in its revelations of desire.

fuck. just a taste. all he wanted.

hm.

maybe later, once katsuki’s dumb little omegan mind had gone all fuzzy and distant.
for now, he simply focused on getting him to create more slick, to make his cock harden until it was at full length and he could finally do what should’ve been done the moment he had presented.
cw // sounding

removing his touch, he quickly grabbed the instrument from the selection of toys he had beside him. toys which katsuki didn’t even realize weren't meant to be there.

such a stupid little thing. so easily tricked and distracted.
with nimble fingers, he grabbed the long, silver object, small bumps adorning the length.

it wasn’t too big, he couldn’t very well scare the omega away from the training, but he knew it wouldn’t be quite comfortable for someone as new to all of this as katsuki was.
and so, as he slathered the sound with lube, he released his scent, finally allowing the tiniest hint of arousal to travel through the air.
the hum katsuki released at the pheromones wasn’t unnoticed, nor was it very surprising. after all, everyone knew the way alphan scents could affect omega’s. leave them all dazed and malleable.
the blond barely even noticed him grabbing his dick, pulling the foreskin lower and revealing the wet tip, and finally, lining the sound up with the hole. only then did katsuki look up, eyes wide and panicked as izuku started to push just as he spoke.

“w-wait, doct- oh!”
the request was ignored, and izuku simply kept pressing, pushing until the enlarged end was pressed up against the tip. slowly, he pulled it out a few inches, only to press it back in and cause katsuki to moan, cheeks heating up as the sound escaped him.

“perfect.”
he released his length, letting it fall to his stomach as he grabbed the second instrument he would need - the speculum.

after all, he did need to make sure his omega was healthy.
before he could use it, he pushed a finger inside of his hole - even through the latex barrier, he could feel the heat, the tightness surrounding him.

beautiful. fucking perfect.

it would feel like heaven around his cock, he already knew.
quickly, he angled his finger, making sure to find his cervix before slowly pulling out, but not without pressing against that soft spot on his upper walls, the spot that made katsuki whine as his cock twitched.

izuku grinned at the sight.

sensitive.
he covered the speculum in lube, pressing it against katsuki’s twitching hole, and the omega rose his head.

“wait, no, wha-what is that?”

he pressed his hand onto his stomach, trailing it lower until his thumb could rub against his sensitive little clit.
red eyes went blurry, filling with tears as he flinched and whimpered.

“don’t worry, pup, i just need to open you up and make sure everything’s okay. it won’t hurt.”

well, this part won’t hurt.

he wasn’t quite so sure about the rest.
he still hadn’t decided what exactly he wanted to do with the pretty little toy he’d received.

there was plenty of time to decide, it would be fine.
finally, he pushed it inside, and with quick reflexes, caught the leg that katsuki removed from the stirrups.

before he even knew what was happening, his fingers were slapping down onto his clit, leaving it red as katsuki yelped and stared up at him in shock.
izuku didn’t let it deter him - the omega had no idea what was happening, anyways, there was no need for him to know izuku shouldn't have done that.

“now, katsuki, i told you to keep your legs in place. be a good omega and i won’t have to do that again, okay?”
hesitantly, katsuki nodded, blond strands of hair falling down his forehead as his toes curled and he kept his gaze on him.

“good boy.”

and with that, he spread the speculum, revealing the soft, velvety insides of the omega as the blond whined and shifted.
he could practically see the slick, the wetness coating his walls, the perfect little cunt.
he’d gone through the motions quickly, yet efficiently, making sure his pretty pet was okay as he carefully told him what each move he made meant - except for the gentle touches to his twitching clit, those remained a secret.
but as soon as he pulled the speculum out and watched his hole wink and close shut, he simply knew he had to give him a reward.

after all, he’d been so good for him. so obedient and patient.
the gloves were pulled off - the pretence of giving a fuck about wearing them was becoming rather irritating. he wanted to feel him, feel the tightness, how wet he was, how much he wanted it.
and so, without preamble, he pushed two fingers into his cunt, thumb of his other hand pressing onto his clit as he began to drag the digits out, moving them in and out as he continued to rub circles into the sensitive nub.
katsuki convulsed, a moan escaping him and hips hitching upwards as his cock twitched and cunt leaked slick down to his ass - which izuku knew he would have to fill up too.

good omega’s took their alpha’s in all holes.
“mi-midoriya-san, i-i feel weird.”

“oh?” he sped his movements up, crooking his fingers and making sure to hit just the right spot as the sound of katsuki’s wet cunt being filled over and over again surrounded the room. “weird how, puppy?”

“t-tingly, d-doctor, i-it’s weird, i-”
“do you want me to stop?” he slowed down, expression earnest and concerned as he tried to prevent himself from grinning at the way the omega tilted his hips down, pussy clenching tightly around him as if he were worried he would leave him empty and without release.
surprisingly, the omega shook his head.

izuku resumed the movements, pushing and pressing as katsuki writhed on the table, face contorted in pleasure as those nearly-white eyelashes fluttered and tears spilt past his cheeks like crystals.
beautiful.

the most beautiful fucking thing he’d ever seen.

"d-doctor, s-something's c-coming, i-"

"let it go, baby, just let go."

and soon, he did.
cum weakly spurt around the sound as katsuki nearly screamed in the room, pussy clenching tightly and clit throbbing as his hips bucked upwards and drool slid down his chin, eyes rolled back and entire body trembling from his first orgasm.

izuku's alpha growled at the sight.
his omega, so ruined from something as simple as his fingers.

katsuki lay there limp, eyes closed and chest heaving as izuku pulled his fingers out.

he couldn’t help it. he simply couldn't.
those same fingers dragged across his lips, leaving a trail of slick behind, and finally, he trailed his tongue over them.
moaning at the sweet, caramel flavour bursting on his tastebuds, his lips wrapped around the digits, sucking and licking until every last drop finally disappeared.

even then, he craved more. always more. he was sure he would never want anyone else. no one would ever be enough.
when he looked down, the omega was gazing up at him, and even with the glassiness of his eyes, there was a smidge of confusion in that pretty shade of red.

izuku merely smiled. “just making sure everything’s okay, don’t worry.”
katsuki nodded, his exhaustion seemingly pushing his concern to the back of his pretty head.

but, izuku wanted more.

he needed more.

he needed to ruin him.

“now, let’s see if you can take a knot.”
Two questions for the next update!

Question 1.

Would you like to go back to Katsuki's POV or stay in Izuku's?
Question 2.

What exactly do you want Izuku to do next?
before the exam, all his mother had told him was that he wouldn’t feel a thing, only slight discomfort and nothing more.

but katsuki disagreed - he felt too much, far too much.
sweat dripped down his temple, his hair sticking to his forehead as the pheromones of the alpha between his legs coated his sticky skin, filling his mouth until he could practically taste the desire and lust the man felt.
worst of all, those tingles in his pussy did not dissipate. he didn’t understand why the doctor made him feel that way, what the point of it all was, but he was sure the man knew what he was doing. his techniques may have seemed strange but katsuki knew this was for his own good.
surely, this would help him get through his heat. the alpha was only making sure he was as healthy as possible.

and judging by the smile on the man’s face and the healthy flush covering his cheeks, he seemed to have passed whatever test /that/ may have been.
but his last words stopped him from purring in pride, no matter how much he wished to do so.

with all the strength he had left in his body, he lifted his head, and at the sight of the doctor unzipping his pants and pulling out his cock, his eyes widened.
he looked up at the ceiling immediately - he wasn't supposed to see such things!

with his head shaking, he moved to close his legs shut once again.

but those strong hands gripped his thighs, spreading them until he had no choice but to hold the position.
only a second later did he feel the harsh sting on his sensitive clit, his hole throbbing from the strike as he gazed up at the doctor - but he looked different, expression harsh and stern and so unlike the kind-looking man that had taken care of him minutes ago.
“katsuki,” he said sternly, pressing katsuki’s legs back onto the stirrups and tightening his grip as katsuki’s breathing sped up. “i told you to stay still, don’t close your legs. i’m trying to help you here and i can’t do that if you don’t listen.”
“o-okay, midoriya-san, i-i’m sorry.”

his expression brightened once again, hands rubbing soothing circles on his thighs before they reached his cunt.

“good boy.”
he ignored the way his tummy flipped at the praise, scent sweetening as looked down once more, right at the man’s cock.

it was big. far bigger than anything he’d ever seen before - thick and long and intimidating with the red, shiny tip and the veins trailing down its sides.
katsuki wasn’t quite sure if they were all supposed to look like that. his own was rather small in comparison.

surely, the doctor would’ve told him if there was something wrong with him, though.

he had nothing to worry about.

well, almost nothing.
because suddenly, the doctor was spreading his puffy lips apart and trailing the head of his cock in between them, over his swollen clit and down to his hole.

over and over again until katsuki was twitching and that same heat he’d felt earlier was back in his body.
but he still didn’t quite understand what the man was doing.

what sort of test was this?

he... he said he’d have to learn to take a knot but... surely he wouldn’t use his own? that wasn’t what good omega’s did, good omega’s didn’t just take any knot.
the tip of his cock caught on his hole, and just as he started to push, katsuki yelped and shuffled away.

“w-wait, no, m-my mom told me to only let /my/ alpha p-put his th-thing inside of me, you can't do that!”
she did! she said he had to be good and pure for his future mate, he couldn’t sully himself by letting any alpha take him just like that.

the doctor smiled, sugar sweet and revealing none of the thoughts he must've been having.
a hand cupped his cheek, wiping away the remnants of the tears he had shed as he sniffled and blinked back the wetness from his eyelashes.
when he focused, midoriya-san was looking down at him, expression kind and patient as his hands trailed lower and lower until they reached the edge of his gown.

katsuki thought maybe he would pull it down, hide his modesty and finish the exam right there.
instead, those clever fingers inched upwards, trailing across his abdomen until they reached his chest, forefingers circling around his pebbled, pink nipples before pinching, pulling upwards and releasing them.
katsuki yelped at the feeling, but the heat rushing between his legs was undeniable.

the doctor mumbled to himself, words incomprehensible, but katsuki was sure he spoke of how ‘pretty his tits were.’
he almost wanted to kick him, tell him to fuck off, he didn't /have/ tits! but he bit his tongue and kept his mouth shut as the doctor continued to toy with him.
a moment later, the doctor shook his head, focusing back on him as his hips inched forward until the shaft of his dick was rubbing against his cunt.

katsuki shivered as the man spoke.
“oh baby, don’t worry. right now, i /am/ your alpha.” katsuki frowned at the words, head tilting to the side in confusion.
and yet, midoriya-san simply continued to play with his chest - which he knew was part of the exam, his doctors had checked this particular part of him before, but they had never been quite so thorough.

still. midoriya-san wasn't his alpha, he didn't carry his bite on his body.
the man must’ve caught his confusion, and he chuckled.

“alpha’s take care of their omega’s, yes?”

katsuki nodded. yes, that was right - alpha’s took care of their omega’s, and in return, the omega’s made sure their alpha’s were happy. that was how it worked.
“aren’t i taking care of you right now? making you feel so good and making sure you’re healthy?”

oh.

well, that was true.
midoriya-san had been very kind to him so far, taking extra good care of him and being so good with examining him. even the pheromones he was releasing were helping keep him comfortable and pliant - the alpha /was/ taking care of him. he was right.
the doctor spoke as katsuki frowned in thought.

“and look at what you’ve done.” he said as he thrust forward, pressing his cock firmly against him as it rubbed against his clit.

katsuki whined at the pressure.
but he didn’t quite understand what exactly he’d done, he’d only just been laying there!

the alpha continued. “you’ve made me so hard. you should know that a good omega always takes care of their alpha, they never let their alpha be in pain.”
katsuki’s eyes widened.

w-was the doctor hurting? did he hurt him?

oh no.

the old hag would be so angry if she found out he’d fucked up this badly.

tears brimmed at his lashline.

“a-are you hurting, midoriya-san?”

“oh baby, i’m hurting so badly.”
eyes stinging with tears, katsuki subtly shuffled closer.

the doctor was right - he /was/ his alpha at that moment, and he shouldn’t be in pain. and katsuki was the best omega! he would take care of him!
“besides,” he spoke as he lined his cock up with his hole once again, “this is part of the exam, i need to make sure you’re healthy enough to take a knot in your greedy little hole.”
and with a wide grin, he thrust forward, sheathing himself fully in katsuki’s cunt as the omega flailed and screeched at the wide stretch.

too much. it was too fucking much - he felt as if he would break, remain unable to move from the width of the cock inside of him.
but the pain was overshadowed by the rising pleasure within him.

the length was pressing down onto all the right spots inside of him, his omega purring at just how big the alpha was, how good he could knot him and fill him up with pups.
the groan midoriya-san let out was filled with relief, and katsuki knew he was helping him already.

a sense of pride filled him - he was being good, a good omega.
and so he forced himself to relax, to take him in until his pelvis was grinding against his clit and his hands were gripping his waist.
but just as he had finally calmed himself, the doctor started to move, immediate thrusts which pushed him up the table, punching sounds out of his mouth that he never thought he’d be capable of making.

“shit, you’re fucking tight.”
the words meant nothing, he could hardly hear them from the ringing in his ears.

all that mattered was that he didn’t stop, he never stopped making him feel this strange way, touching every part of him as he whined and moaned and cried once again.
fingers trailed down his abdomen, lightly grazing the tip of his still-plugged up cock.

“hm, maybe next time we’ll put a pretty cage around this cute little thing, we wouldn’t want you touching it, would we? good omega’s cum only with their holes, don’t they, puppy?”
katsuki wasn’t listening.

he couldn’t.

not when suddenly there were fingers pressing onto his clit and rubbing in circles until his back arched and his toes curled.

he could feel the coil rising in his tummy, that same thread of tension ready to snap once again.
but this time, it was different.

something was different.

just as the pressure became unbearable, he realized just what it was.

“m-midoriya-san, p-please stop, i-i’m gonna pee, ple-please, oh, n-no.”
the words only caused him to speed up, a cruel smile spreading on his face as he pushed harder, faster, angling his hips so that katsuki had no choice but to sob and moan and /beg/.

“let go, puppy. show me how much your slutty cunt loves my cock.”
as if he had no choice, he did as he was told.

the thread snapped, and all he could do was let his eyes roll back and his cunt spray that strange liquid all over the doctor's abdomen, his hole spasming and dick twitching as he wept in pleasure.
the alpha kept moving, thrusting and fucking into him until his knot began catching on katsuki's walls, popping in and out over and over again.

and finally, with one last push, it caught.
the knot expanded, growing as the alpha's own groans got muffled with the sounds of katsuki's moans.

he was barely present, barely aware of what was happening as he lost himself in the haze of this unfamiliar sensation.
there was nothing he could do but writhe and cry as he pulled on the restraints and allowed the doctor to fill him up with cum until his tummy was bloated and he could hardly breathe.
and as he lay limp on the table, he closed his eyes shut and let the exhaustion take hold of his mind.

izuku could see the moment the poor thing passed out, drained by the first orgasms he’d ever had.

with a soft coo, he brushed away the wetness from his cheeks.

pretty little omega.
he was lucky to have found himself knotted inside such a lovely being, so beautiful and pliant.

even then, he kept pumping him full as he pressed down onto his stomach.

the omega merely whined at the feeling.
he could feel the drops from where katsuki squirted sliding down his skin.

izuku was quite amazed the omega had done that - he never expected him to squirt during their first time together.

he simply had to see if he could make him do it the next time they did this.
while he waited for his knot to go down, he pulled the sound out of katsuki’s cock, smiling at the whimpers coming from the omega as he threw the object onto the table beside him.

hm. hopefully, he would get a cock cage on him soon - it would look so pretty on him.
soon, he was able to move, to pull out and watch as that beautiful, pink cunt attempted to close shut and keep the cum inside.

well, izuku was sure he could help with that.
he tilted the boy’s hips up, holding him still with one hand as he grabbed a plug from the side. a wide and heavy thing, a pink jewel at the end of it.

lubing it up with the boy’s own slick, he pushed it inside, revelling at the way the omega simply /took/ it. so good for him.
he was sure he would be able to get him to keep it inside until he finally showered - he would probably spew some bullshit about nutrients and how it was healthy for the omega to keep themselves plugged up.

he would think of something, just to keep him full.
and with that, he finally let him rest, quickly undoing his restraints and rubbing at where the skin had reddened.

before he could move away, a rumbling noise echoed in the room, a sound so precious izuku nearly wept right there.

a purr. the omega was purring.
he was already thinking of it before, but now he was sure of it.

the omega would carry his bite, his mark.

besides, he knew of the bakugou’s - he knew their views of omega’s and their traditional treatment of the subgender.
only a quick phone call was all it would take for them to arrange a meeting and allow him to prove he was capable of taking care of their son, mating him, breeding him.

he would be his within a matter of weeks.
