mega bastard

katsuki bakugou is becoming a thorn in your side.

you’ve both been metaphorically and somewhat literally glued to each others sides since highschool. it’s not necessarily a bad thing, to be quite frank katsuki is something of a deterrent in a world of second genders and pheromones— something you capitalized on in high school.

being an omega hero isn’t something entirely world shattering, but it’s a position that comes with lots of stereotypes— stereotypes you fought tooth and nail to fight against in your younger years. being one of four omegas in your class was...irritating, to say the least. lots of preconceived notions that you needed to be helped with trivial things, and while your classmates intentions came from a good place it was maddening. save for katsuki, back when he had no restraint with his anger and aggression, he didn’t coddle you like your classmates did. Labeled a brute for his actions towards his omega classmates in trivial interaction or sparring, you thrived on the normality— katsuki was an ass to everyone. Your omega was placated, finally encountering an alpha who wasn’t belittling her with preconceived daintiness.

it was easy to hang near katsuki, ignoring the atrocity that was his vocabulary. eventually like the rest of the peanut gallery that was the bakusquad, you just existed alongside katsuki— which meant that you grew on him. katsuki swears up and down that you’re all a nuisance but you’ve seen him go up to bat for all you at some point, you knew you’d all made some sort of ragtag pack with one another. this was rather amazing to you at the time, not to sell yourself short but you’d never really imagined belonging to a close knit group of friends— especially realizing that they understood when it was appropriate to step in for you. katsuki in particular had a knack for being at the right place at the right time.

During your second year you fumbled.

interning with miruko had its perks, a top 5 hero with raw strength, cunning, and the drive to just keep going— and an omega. landing and internship with her had been a dream, even more-so when you learned she’d been watching you since your first year because of the festival. bright eyed and eager, nothing could have dampened your spirits— neither katsuki and his usual moody behavior or the standoffish alpha from shiketsu. yes, you all had landed an internship with miruko and part of you was...worried? katsuki had never looked down on heroes based on their second genders but you couldn’t speak for the shiketsu alpha, both alphas interning under an established omega hero put your inner omega on edge— you didn’t quite know why though. but you chose to squash the feeling and enjoy your internship with who was essentially your idol and continue on.

then you started getting sexually harassed.

his name was omori kisai and he was the worst. hailing from shiketsu, known for their dignified schooling, he was far from it. salacious comments dropped when no one was listening, less that appropriate touching when passing by and just general ick that had your skin crawling and omega snarling. it was easy to brush it off as banter the first time, section off the awkward contact as an accident. The second time you made it clear the comments were not liked and the touches far from appropriate, after the third time you’d snap an insult or have to hold a trembling fish from making contact. but it was coming to a head and your suppressors could only do so much to hide your souring scent. looking back you should have said something, but your pride had told you that it was a necessary step to overcome and push through— that he wouldn’t be the last. it weighed you down, day by day, a heavy cloud that wouldn’t let up. one particular bad timed comment brought tears to eyes and shame to your entire being.

thankfully, as time would come to show, katsuki tended to nose into your dilemmas.

the day prior to the abrupt end of your harassment  you’d been tripped up by a villian and had fallen a sizeable distance into a pitiful excuse of pond. of course, omori had taken this as an open invitation to mock you and then offer you his shitty hero costume cloak— not without hinting at you returning the favor ‘somehow’. yeah right. you had stomped off, unaware of katsuki’s presence nearby. come next day, omori avoided you like the plague and katsuki not so subtly stuck to your side like an unwilling chowchow— all growly and temperamental. but his constant presence rubbed his scent off on you. despite his less than chummy attitude, you weren’t mad; katsuki smelled like cinnamon spice and whiskey with hints of burnt caramel— absolutely overpowering yet decadent all the same.

you tried not to think about just how much you enjoyed his smell. your omega was purring about it.

the omori incident was the beginning of katsuki’s subtle hovering. though you pried the truth of his involvement in omori leaving you alone after offhandedly bringing it up to mina and jirou one day, katsuki helped you out of situations as invasively as possible time and time again. by the end of third year it was no secret to you of your classmates teasing of your relationship with katsuki; an amiable and prideful omega and the irritable powerhouse of an alpha. you brushed it off because...well you didn’t know why, but katsuki’s seeming indifference to the teasing had you quelling every jittery happiness your inner omega expressed at the thought of katsuki being your alpha.

now, three years out of highschool and beginning to climb the ranks, katsuki was becoming testy— and for the life of you the reason couldn’t be more opaque.  you both work at the same agency, and due to the nature of your quirks you spend all your time together due to their compatibility. compatibility was a bitter word for you, katsuki and yours supposed compatibility had been talked about for some time now but the sobering reality is that perhaps you two were simply good friends— and now sharing your omegas endearment for the explosive alpha had reared its ugly head.

your heat was a week away and already you felt the familiar fatigue begin to lap at you alongside general moodiness. all that coupled with the annoying need to be around katsuki was maddening and sprinkling his own extra grouchy attitude on top and you were ready to snap. in hindsight, that should have been your cue to take an extra week off— instead you chose to once again to champion pride instead of your intellect.

you could have stayed home this morning, you should have.

patrol had been slow, not particularly unusual but favored nonetheless. face raised to the slowly dipping sun you couldn’t help but sigh, the warmth of the late afternoon sun was heaven sent-- you could sleep standing up with much issue. it remided you katsuki, strangely enough though most things did recently.

the sound of screaming and rushing feet shook you from your drowsy stupor. Set on alert, you spied the source of the sudden discordance and found several villains causing a commotion. quickly calling for backup for you before finding yourself facing a hulking mass of green charging you head on. tranquility gone, it was time to fight.

the ache in your body could not be more apparent but your humiliation ran more rampant in your system than any ache or pain could, your fatigue more than present as your body hummed with warmth. leave it to you to get stuck face down and ass up amongst the trashed ruins of what was an office building, weighed down between a broken desk and a collapsed bookshelf. the villain you had engaged with, some self-named idiot calling himself cruel croc, packed a punch and your bruised body and rendered office floor were a testament to that. of course, you’d done quite the bit of damage to him yourself before the entire floor collapsed underneath you both— rendering the meathead unconscious under a rather hefty pile of concrete and debris whereas you were pinned and to utterly weak to do much.

the thrum of your heat was beginning its path of vengeance through your body, feeling too pliant to get yourself out of what was otherwise easy to fix problem. you were feeling it, bad. the heat of your clothed cunt was beginning to become too apparent, unconsciously squeezing your thighs to provide relief to no avail. no, this could not be happening right now of all times. but as much as your inner monologue fought to try and will away your heat, the warmth was becoming too much and sudden breeze of wind had you trembling and whining. the feel of slick beginning to wet your hero costumes spandex set your hazing thoughts into sudden panic, if cruel croc woke up or if another villain came across you would they be above...the thought alone could’ve made you puke. flashbacks to second year had you bucking wildly for freedom, you wouldn’t let anyone have the opportunity for—

“ OI! Shitty ‘mega were are you? Are you—“

you stilled, biting hard to keep your mouth shut. your omega was whimpering, desperate for the alpha, HER alpha to relieve her from her heat. on a normal day she could melt into his scent, but right now? she could drown in it and die happy. with his scent getting stronger the closer katsuki clambered toward you, the more the head haze grew-- the slicker your thighs became. the whimper you let loose was pitiful, the need for some sort of stimulation to your cunt becoming near painful the longer you remained so close yet so far from katsuki. the pathetic little “alpha” you whined as you heard him quickly approach from behind would’ve been utterly embarrassing to you in any other situation.

but if you could have turned to see katsuki, you would’ve been met with the look of an unmistakably feral alpha-- pupils dilated to hell, fingernails blackened, and canines elongated and sharpened. but what you lacked in sight, you could hear and smell.

katsuki was the definition of an alpha as is, but the way he was pushing his scent out was like a big red sign that screamed ‘DANGER’. To you, it had you feeling utterly submissive-- if you weren’t already face down and ass up you certainly would’ve moved into position.  practically salivating at the thought of what katsuki could do--

the heated palm on the globe of your ass is thought pausing, the sudden heated touch coaxing a sugary sweet moan from deep in your throat-- the small touch quickly turning to rough palming at your moaning. tt feels so good, but you want more. need more. 

“Please, need more Alpha” it's breathy and whiny, something you're far from day to day but it feels too natural escaping you. mewling at the ghost of a touch over your clothed cunt, your blubbering when it presses harder-- escalating you to tears of frustration when it ceases. practically feeling katsuki’s harsh breathing near your cunt you begin to wiggle and wail with all manner of unrestrained vigor; chanting alpha and katsuki like a prayer and begging for relief like a sinner for forgiveness. it’s working, you know it is, if katsuki’s breathing is anything to go by but he refuses any further touching. you want katsuki everyday, but right now you need him. 

“Only want you Katsuki, please it’s only been you,” you hiccup your words through a shrill plea, but the tearing of your soaked spandex sends an excited chill down your spine. your legs tremble with excitement when katsuki grips the tops of your thighs and spreads them-- revealing your drooling cunt. it’s both too much and not enough all at once and you wiggle once more, yelping from a smack to your left ass cheek. it’s not particularly painful, not even as katsuki rubs over it right after the hit, but it quells your wiggling nonetheless. you open your mouth to urge him on but he beats you to it.

“No one else, you got that ‘mega? No one gets to see you like this, no gets to touch you like this-- your mine,” he punctuates his declaration with two of his deliciously thick fingers in your cunt and you squeal, “ you got that? I’m your alpha, always have been always will be.” nodding despite yourself, you struggle for words with his fingers pumping in and out alongside the ghost of pressure on your clit “Yes! Yes, I’m yours Katsuki!” you babble your words already teetering on the precipice of your first orgasm. it takes a pickup in pace and a rough rub along your clit and your wailing, slick streaming down your thighs as your first orgasm crashes into you.

despite the pleasant haze in your head, you faintly hear zippers being undone and the shuffling of clothes. licking your lips, you perk your ass up as much as the heavy bookcase allows, purring in excitement like a spoiled cat. The rough grab of your hips leaves you gasping, feeling the length of katsukis dick along your thigh-- long and heavy. you're salivating as he lines himself up with your weeping cunt, ramming his entire length in you with little regard. stars shoot across your vision and your ears deafen, crying out at being so full. it feels wonderful being stuffed this full and you babble it to katsuki. if you could see him, you would see just how prideful and smug he looked-- only he can take care of you like this, none of the other shitty alphas can take care of you this well.

katsuki sets a rough pace, drawing himself out slowly like he’s aiming for you to feel every vein of his dick before slamming back into you. your poor cunt clenches sporadically, drawing groans and growls from your alpha and all you can do is choke on broken moans because the way he feels churning your insides is downright sinful. you felt a band begin to tighten in your belly, your broken moans evolving into babbling-- how good katsuki was making you feel and how he was the only one who made you feel this good. it spurred him onward, fucking into you with more vigor alongside groans of your names and his own praise for you. “Good fuckin ‘mega”, “Takin’ me so well”, and “My perfect little mate” were some of the praise you could catch and had you preening. All of it combined you felt the band tighten and you couldn’t stop yourself from sobbing out. feeling the base of Katsuki’s length begin to swell, you could only salivate at the thought of being knotted.

“Want your knot Katsuki! Alpha I need it”

 at your blubbering demand, katsuki faltered in pace for only a moment before a deep mix of a groan and growl ripped from his throat. grabbing and bending your leg upwards he fucked deeper and faster into your battered cunt, the new angle sending you hurtling into your orgasm. eyes rolled back and tongue, you felt utterly boneless-- momentarily brain dead before screaming out at Katsuki knotting you, his own groan of pleasure mixing with yours as he filled you impossibly full with his seed. 

 trembling underneath him, you were only a fraction aware of movement above you before the weight of the bookcase vanished from you. weakly you glance back up at your alpha. your surprised to see just how feral he looks, no doubt you’ve pushed him into his rut. whimpering as he moves down upon you, he nibbles and kisses along your jaw and neck before biting down on you scent gland. a flash a white hot pain curtailed by just as intense pleasure wracks your wrecked body but the dopy look of happiness pulls a low purr from katsuki.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

you know you're fucked as the last of the pretty white line vanishes through the end of a cut-up straw and into your nose. that too pretty smile tooru's wearing almost looks sinister as the feeling of prickles dances across your brain and the feeling of slight numbness snakes up your appendages. it's cemented further when drowsiness sinks in.

worst of all, you know you've lost when tooru's featherlight touch across your bottom lip has you sucking his thumb like your boyfriend isn't somewhere else in the same house

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

leading up to the frat party, you were excited ! time spent with your roommate was always fun, your partner in crime for getting wasted silly before proceeding to call your boyfriends to be picked up and continue the fun from there.

their frat's parties are always choice, thematic some days and just a reason to drink and make poor choices others. your poison of choice always being egging hajime on throughout the night to be fucked dumb when he's pushed beyond his limit-- the perfect fun for you.

but there's always tooru.

it's been too many times to count where you think you've finally got hajime right where you need him and then tooru's there to effectively whisk hajime away-- always with a snide reminder that you're there with your roommate, his girlfriend so 'why don't you go find her, she'll get lonely!'

ironic, considering that if she and you were up to trouble together he'd badger you over being negligent of hajime.

regardless, you fully entitled to enjoy yourself tonight-- tooru be damned.

before you could fester longer on the leech that was tooru, your roommate poses a comment about the outfits planned for tonight. it's enough to steal away your attention, and you find yourselves trying and tossing off clothes interspersed with chatter and gossip of all manner. by the end of it, you look downright sinful-- dressed in a silky feeling black bodycon with lace trim.

the intention is to rile hajime up, get him irritated having to be watchful over you to keep his sleazy frat brothers away. except for tooru, he's always the exception. he couldn't let any of his other brothers be the exception? you'd take temperamental kyotani over tooru any day. it's only a minor bonus kyotani is nice to look at.

by the time your roommate is ushering you to the uber you're quite tipsy, still aware of yourself but relaxed enough to giggle along to the lame jokes your uber throws over his shoulder at you two. idly, you think he's kinda cute.

the party is in full swing by the time your uber pulls up, people idling out on the lawn in stark contrast to the blaring music coming from the house itself. hajime and tooru are waiting outside for the both of you as you exit the uber. giving the uber a sweet smile before closing the door.

you try to ignore the lingering look tooru fixates you with as you make your way to the boys.

" tooooruuuu~" your roommate all but throws herself into her boyfriend, giggly and happy to see him. he returns the embrace, peppering her cheery face in kisses before returning her greeting "hi princess, you look ravishing as usual."

you fight to keep the cringe of your face at the nickname, opting to ignore their sugary-sweet pda in favor of hajime. you link your arms behind his neck before blinking up at him, pressing a chaste kiss to his chin before grinning cheekily " hi bubs, missed you today". his own hands settle on your hips, rubbing softly at the material of your dress before smiling down at you. he mumbles his own greeting before pressing a kiss to your temple, beginning to drag you inside.

you don't miss the familiar stare of someone staring down your neck.

all too quickly, between games of cup pong, kings cup, and random shots; your separated from hajime and squished between hanamaki and matsukawa on a ratty couch in the garage with an odd group of people. you're vaguely aware of matsukawa's arm thrown over your shoulders.

you don't try to move it.

you're half engaged in the conversation going on, between being drunk and swimming in the heady smell of weed, you're just kinda sitting there zoning in and out. there's a sizable bong being passed around, and despite only having met them a handful of times prior, hanamaki and matsukawa seem to know better than to offer you a hit-- at least that's what you tell yourself. across from you, there's a blond girl cutting lines of coke on a handheld mirror, looking up briefly with a raised eyebrow in question. you've met her prior, you've literally done lines with her, but her name is escaping you.

you feel stupid.

you're about to nod along when matsukawa's arm is thrown off you, two hands coming down on your shoulders in a bruising grip. you wince when you meet tooru's chocolate eyes.

he looks kinda pissed.

"y/n ! I've been looking alllll over for you !" his voice is as princely as ever, but the sneer on his face and the barely there anger under his tone pisses you off. you decide to push him before he starts pushing you.

"where's 'princess' at? can't believe you left my poor roommate all alone in this house" you tsk and pout, shaking your head. tooru's face momentarily sours before he's looping around the couch and dragging you to your feet, pulling you to the door without a word. you glance back briefly at hanamaki and matsukawa, but they look just as put off as you.

weird.

you follow, not sure if it's curiosity or just being drunk for you simpered obedience. you're led past hajime's room where you hear noise-- notably hajime and someone else but you can't think too hard about it with tooru's tightening grip on your wrist. this would be nice if it were hajime pulling you along. you stop in front of a door at the very end of the hall.

it's tooru's room.

volleyball trophies and keepsakes line the shelves, along with other commemorative keepsakes. a picture of him and your roommate, him and hajime, a group picture of the four of you as well. you're about the prod for answers when he beats you to it.

"don't worry about my 'princess', she with hajime right now!" he sneers down at you, loving the confusion that crosses your pretty little face before continuing "i figured i'd come check in on you since hajime seems to be doing a shit job of it." you're only partially surprised by the drop from his usual cheerful speech and vocabulary, but to hear him come at hajime unabashedly is strange.

it's actually really fucking weird all things considered.

"what do you mean by that? why's he with her..." and not me? the sentence practically finishes itself and tooru's sneer grows as your mind begins to tumble over itself. " you know, maybe he just can't handle you anymore? he's always bitching to me about you" tooru sighs, hand raised to his chin thoughtfully. something in your chest aches at the thought, mind nowhere near sober enough to see past tooru winding you up.

"you know, I tried arguing with hajime about it on your behalf. sure you're needy as hell and a borderline nympho but you're soooo cute! if i wasn't dating my princess, I wouldn't hesitate to steal you away~" it comes out teasingly, but his words are downright awful. you're not needy...right? sure you like sex, but hajime never complained about it.

you kinda feel like shit.

turning on your heels, you make for the door before tooru latches onto your wrist again. that same bruising grip back again, you whirl on him ready to lay into him before he shakes an orange pill bottle in your face. eyes narrowed, you glare up at him. what the hell is he up too?

"to make it up to you for bumming your night and causing you to miss out saeko's cheap shit, why don't we have a little pick me up?" his sneer is gone now, simmered down to what could be a genuine smile. you weigh your options, dull red flashing lights go off in your mind but safety be damned-- you need a pick me up. "fine, fine. i'd rather get something from you than just anybody." tooru looks a little surprised at your admittance, but you plop yourself on his bed before you can stare up at his pretty face any longer. he turns his back to you in favor of his desk, clearing space and procuring his debit card and a dollar bill before popping the lid on the pills and grabbing one.

you don't watch him crush the pill, and that's your fatal mistake.

all too soon, zoned out staring around the room while lost in your pitiful thoughts, tooru calls you over. "you're a big girl, I'm sure you know how to snort it" his voice is teasing, but you fail to notice just how focused he looks staring down at you. you grab a cut straw, no longer than two inches, and line one end to your nose and the other to the white line.

it feels wrong.

you know you're fucked as the last of the pretty white line vanishes through the end of a cut-up straw and into your nose. that too pretty smile tooru's wearing almost looks sinister as the feeling of prickles dances across your brain and the feeling of slight numbness snakes up your appendages. it's cemented further when drowsiness sinks in.

worst of all, you know you've lost when tooru's featherlight touch across your bottom lip has you sucking his thumb like your boyfriend isn't somewhere else in the same house.

god this so wrong, but the way tooru ushers you backwards until the back of your knees meet his bed, and you fall on your back feels nice. everything feels nice, his thumb in your mouth, his comforter on your back. the way he's staring down at you, laser-focused on just you... it's very nice.

but incredibly wrong.

hajime is in a room nearby, the fact eats at you.

tooru withdraws his hand from your face, thumb briefly pressing along your plush lips before crawling over you. he buries his head in your neck, nibbling and sucking along the length of it like a starved dog. you whimper, it's wrong but why does it feel so good? a particularly nasty bite forces a moan from your mouth, mind spinning at the pleasure despite the numbness.

you're terrible for getting off on this, you're a terrible girlfriend. tooru, evidently, is a terrible boyfriend. he drugged you but who's gonna believe you? you did agree to do it, you didn't ask what it was. your thoughts are spiraling.

tooru's hand leaves a blazing trail up your thigh, sliding up underneath your little dress and squeezing your upper thigh. you don't like this. weakly, you grab onto tooru's wrist in an attempt to halt his movements. he shakes it off, kissing along your jaw before mumbling to what you assume is more-so to himself than you.

"knew i was gonna fuck you when you strolled up in this, hajime's really missing out tonight"

tears bubble to your eyes.
