good little omega
— He was an alpha, you were an omega. Can I make it anymore obvious? He was a crime boss and you were a movie star. What more can I say? Oh, he wanted you, really wanted you, but you swore you would never, ever need an alpha.

You sat before the mirror, your eyes intently staring at your reflection. The people around you running around, chaotically bringing brushes and pencils to your face, the smell of chemicals in the air, tickling your overly sensitive nose.
“Are we ready?! Is Y/n ready?! I don’t think she’s ready?! We need to be out of here in five minutes, people, let’s hurry it up!”
Breaking your gaze from your reflection onto your agent in the background, you sighed softly at the growing sour and distressed omega pheromones. Oh, you realized suddenly, your nose unable to keep from scrunching at the mildewy detergent scent, they were really stressed out.
Today was the night of the biggest award show one could attend as a movie star celebrity in Japan. The Motion Picture Awards gave only the most prestigious and prodigious actors and actresses their due. A night of fashion, alcohol, and nervous pheromone pumping alphas and betas in a single room to reveal who was the best this year. Working in an industry such as your own, you had become quite the living legend already at the mere age of twenty-two.
As an omega, you grew up in a society that banned you from enlisting or attempting to join the ranks of the best in just about every field of focus or study. So that even included the area of acting. Casting Directors had always said the same thing each and every time you were forced to present your secondary gender to them all when being called back for auditions.
‘Omegas can’t be movie stars, your heats are too often and too long, they cause rifts in filming schedules this project cannot afford.’
‘We have too many prime alphas on set. Our film's projected main character is an alpha, we wouldn’t want to be caught up in a lawsuit should she find you to be too… fertile.’
‘Omegas can only be good, suitable nurtures and well, mothers. This movie just seems a bit too intense for a little omega like you!’
Omegas can’t do this, omegas can’t do that. Alphas, the pride of society, couldn’t be made to hold themselves back to your alluring scent and occasional heats. Betas, the majority of the population, didn’t feel a challenge when working alongside omegas. Omegas? Well, if there were any that actually existed within the film industry, they were for sure never heard from, or seen of.
At the age of eighteen, you had nearly given up on your long aspiring desire to become the first omega actor or actress to ever grace the scene. But just as you were ready to tell your agent that you were tired of all of the same, repetitive bullshit, a gentle alpha had approached you with an exciting role in mind for you.
Movies and cinematic films had always showcased omegas as sweet, nurturing individuals. For the most part, you agreed that that’s how you omegas were. You enjoyed hugging your close friends, scenting them softly as means of a small pack you had created as none of you were mated this young, yet didn’t ever wish to be bothered by self-righteous alphas or betas. Through many, many biology courses revolving around your secondary gender, you knew that the hormones that made you an omega also affected the brain to accept and view things in a… softer light. But unlike what they taught in school, and unlike what the alphas in society knew about omegas as they could never honestly watch an omega in heat while alone, was that omegas weren’t always the most nurturing or kind.
The week before your heat, the week of, and the week following your heat, you were always irritable, angry, almost cold. You’d flash your small fangs at anyone who dared to approach you with a scent you hated, your heat room never once escaping with everything torn to shreds, and you definitely did not wish to seek any fiber of soft love.
So when the alpha male sat in front of you, a single fang poking out of his lip as he exposed his neck in a motion of vulnerability and conceding to you — the omega — you knew he was serious.
He explained to you his plan on creating a more realistic movie surrounding the brutal truths of what being a single omega was like. Films had, after all, had always depicted omegas as being mated the moment they presented and going as far as saying that there were others means to be coupled to other alphas without actually being marked. It was atrociously wrong of the omega lifestyle, and it always made your stomach curl to see that it was an alpha or a beta actor putting on the role.
But he wanted to focus on the realities. The anger, sadness, and horrors you could face as a single, unmated omega. The director raved that you were the face for that movie and had a soul that made him come seek you out. And without so much as consultation from your agent, you agreed on the spot.
The title of the film had been an ironic one. Good Little Omega was what it was called in the end.
All in all, the movie had done poorly in the eyes of the critics. Many individuals — namely alphas and betas — claimed that the depiction of omegas within the film had been horribly wrong. Omegas were never sad, never homeless, never abandoned by society! That’s what they had all cried the moment the trailer flashed with bright letters:
AND INTRODUCING: Y/L/N Y/N (Ω)
Still, the movie made billions as many went to watch it because they ‘needed to see how horrible the movie was.’ They wanted proof that omegas weren’t cut as movie stars because how could someone who was out of commission for a week every two months be proactive on set. But all they got was a cinematic masterpiece.
You had taken a claim in the industry, one while small, that hadn’t hurt that much because you were much more focused on the fact that you now were a household name. Well, that is until you were nominated for the awards ceremony you were currently about to attend, only that it was the one from four years ago.
You were the first omega actress and now the first omega nominee. You hadn’t won, but that had solidified the step you had in the door. After that, the interests to hire you in omega roles came pouring through the door.
But you were brought back to reality when the setting spray splashed against your face, your eyes fluttering when they covered your scent glands with the flesh-colored band-aids they got for you. Alphas could never complain about you being a distraction if you smelled the same as betas.
Rising to your feet, you smiled graciously to your makeup and styling team, thanking them profusely as your agent placed her hand at the small of your back and began pushing you towards the exit.
“Goodluck!”
“Thank you!”

Shigaraki glared down the table of averted eyes, and his hands brought up under his chin twitched at his annoyance.
“Are you going to say anything, or are we going to remain silent?” he asked, his voice quiet yet heavy in all of their ears as they flinched. “Don’t think you’re going to get away without giving me an answer.”
The sour smell of fearful alphas should have corroded Shigaraki’s nose. It should have done something to unsettle the way that the young head sat on his black leather seat. But as a matter of fact, the young alpha had to resist the way he wanted to bare his teeth in a bloodied smile, his red eyes slit in his cruel lust for fear.
“O-Of course not, a-alpha!” croaked one of the smaller alphas down the table. Shigaraki snapped his eyes towards the yellow-haired croony, his neck exposed for the alpha, eyes refusing to look at his leader. “I-It’s just that, um, I — I mean, we don't know w-what happened to your mate!”
“I thought I gave clear and distinct instructions that you were supposed to have found them by this meeting,” Shigaraki stated, his voice somehow growing colder, meaner yet never once changing as his hands dropped from his chin to rest on the arms of his chair. He tilted his head, watching the pathetic alphas quiver like some scared, stupid omega. “Useless. Get out of here before I change my mind on killing you all where you sit.”
The crowd of alphas left quicker than Shigaraki could blink, leaving behind the reeking smell of scared alpha pheromones.
“Tomura-kun, you killed your mate,” came the singsong giggle from behind him, and Shigaraki didn’t bother turning around, his nose and ears sharp enough to pick up exactly it was behind him.
“They’re all a bunch of pissy lackeys,” Shigaraki simply stated, his eyes rolling as he slowly fell to the back of his chair, red eyes meeting golden ones that shone with mirth and joy. “What do you want, Toga?”
Toga leaned against the leather armrest, uncaring that Shigaraki hated his personal space invaded. The young female was an alpha, much like most of the people within this gang group, but unlike the others, she had a distinct, almost terrifying way to change the way she smelled. She could smell like anyone or any secondary gender. She often preferred to smell like an omega too.
“We have a guest visiting us today!” Toga chirped, her fingers clasping together. “I wanted to introduce him!”
“Bring Giran in,” Shigaraki snapped, his eyes narrowing with no real malice for the alpha next to him who simply pouted at the surprise — not a surprise — being ruined. Giran reeked of cigarettes and cheap body sprays that, when wafted with his distinct omega pheromones, made Shigaraki want to throw up. “Hurry up.”
“UGH!”
Shigaraki’s mouth was set in a firm line, his eyes watching as one of his most trusted allies walked to the table, and taking a seat in the abandoned chairs as Toga purred in happiness, sitting on the armchair of Giran’s chair, arms enveloping him.
“Shigaraki, how are you doing?” Giran smiled, the cigarette that seemed to take a permanent residence in his teeth moving with his words. “I came bearing some great news.”
“What do you have for me?” Shigaraki simply states, his eyes focusing on the letter that is unpocketed from Giran’s pockets and placed onto the table. “Don’t tell me you’re trying to sell me your omega niece again.”
Giran chuckled, looking at Toga, who was smirking softly, “I guess he still hates that joke, huh?”
“Absolutely livid!” Toga laughed.
Shigaraki growled, his mind and his inner alpha snarling at the lack of respect to the command of his question. He outranked them, outpowered them; they needed to respect his orders.
Giran took a deep inhale of his cigarette, sliding the card over to Shigaraki, his eyes averted, but his stance still firm. “I know you go through omegas faster than a teenage boy goes through a pack of tissues, but I think this can answer the pleas you have at night.”
Observing the card in his hand, Shigaraki scowls, unsure of how to feel about the print on the invitation.
“Say the word, and I’ll get you a seat,” Giran whispers, like a sinister god begging a mere mortal to sign over their life for something completely worthless. But Shigaraki knows his worth, and more importantly, he knows in this game he outranks Giran, who would never betray him. In the slightest. He huffs, his back hunched, and his eyes looking with subdued excitement.
“Who else is showing up?”
Giran knows the seat will be wanted that instant.
“No one who could hold a candle to you, alpha.”
“Don’t make me regret this.”
“Of course not, my liege.”

The award sitting in your hand feels almost fake as if the entire night was nothing more than a heat-driven fever dream. You had won, had actually won the most significant award of the night that an actress could win!
“Oh my gods, okay, okay,” your agent muttered beside you. Her eyes glued to the shiny gold statue between your legs. “Well, I know your heat starts tomorrow, and I’ll leave you alone for a week. But I swear, y/n, as soon as your mind isn’t a full-blown lusty heat brained bimbo, we’ll reconvene, and we will make sure you are nothing but the greatest!”
“Yeah,” you breathlessly state, eyes transfixed on the prize that felt like it could melt away any second right now. “That sounds wonderful.”
The car you were in pulled up to your front door, and you felt meek excited the car in nothing but a silk robe and slippers. The dress you had worn that night had already been put back into a plastic bag to be returned to the stylist who had offered to style you for the night. You waved with an almost transfixed look in your eyes as you closed your front door behind you, your heart hammering as adrenaline still coursed through your veins as if you had just been declared the victor of the category yet again.
Placing the trophy onto the table, you sighed in a wondrous, dreamy way.
You had done it.
You had won.
Fuck all those directors who had ever said anything different.
Still deep in your thoughts, you almost missed the knock on your door, and you figured that you must have left something in the car. Walking back over to the front door, your nose curled at the lack of scent, was it a beta?
Opening the door, you don’t remember seeing faces or even a scent of a pheromone. A single cloth wrapped over your head, and before you could send out your painful, fearful moments-from-heat omega pheromones, you were knocked out.
Cold and lifeless, you sunk against their arms, bile rising up to your throat as you know exactly what was going on. You were being kidnapped.
No… please not… not after all of this had happened.
.
..
.
You wake up to the sound of moving feet, sneering laughter, the feeling of coarse, hot, hands on your ass and wet, simmering tongues on your lubricated cunt. The sense is vivid. You can feel the very littlest touch on your body, the layer of scented pheromones on your glands, and slick from alphas — you know it's alphas imprinting themselves on you as a mark of a claim.
You knew about this from high school; it was an extremely outdated and frowned upon version of mating and claiming as it simply turned away any sort of pursuer who wasn’t the thick pheromone individual. You also knew it was frowned upon because if multiple individuals sought mateship with the typical omega individual, it would result in a massive, unsolvable death match. But these alphas, even with layering their scent on you so thick you thought you were turning crazy, didn’t attack. No, they took languid stripes of your fresh, intoxicating slick and growled to you, maybe, how that was how slick was supposed to be.
You wanted to move, to kick the stupid, demeaning alphas in the snout before running away, but in a twist of horrible realization, you soon figured out that despite your alert mind, you couldn’t move your body. Couldn’t shift it even the smallest of bits.
“I hope all you wonderful clients have been able to taste and smell your potential mates out here!” A loud, commanding introduction voice echoed from somewhere where you couldn’t see, his voice vibrating into the straps of your legs, but you couldn’t make a sound or even open your eyes. “As you know, we have such an arrangement for you all, the best of the best, really! We don’t wish to rush, but as always, all of these events are incredibly time-sensitive, so if you would, please alphas, please come and sit down, and we’ll begin bidding on our first of seven beautiful, fertile omegas tonight!”
The words sounded foreign in your ears yet at the same time, something so familiar because this was something you omegas were always warned about. This had to be some sort of omega mate auction, and by the stench of alphas who smelled like they owned millions and killed millions, you were in no doubt somehow caught up in one of the worst ones imagined.
Two long, completely hardened fingers suddenly entered your cunt, and as if for a single millisecond, your mind and your body were able to work in tangent, your hips bucked at the sweet feelings. Oh, your eyes tried to flutter, enjoying the way the two fingers circled the walls of your long lonely cunt.
“Please, alpha, please refrain from touching the merchandise for now, please join us so that we may begin!”
The two fingers buried within your cunt as if it was their right, slowly withdrew out of your pulsing walls, and you heard the sound of sneakers against the hardwood floor and felt relaxed and sickened at how you sort of liked it.
Heat brain, you reminded yourself. Just your stupid, horny heat brain.
You were a celebrity, you mantra, a dignified star who didn’t need a beta or an alpha unless you saw it fit. Right now, as you had repeated many times to the countless amounts of reporters who had asked, you had no interest in someone to share your heat with.
“Alright, and to start off our night in a rolling go! Please, everyone put your hands together for the fertile and beautiful thirteenth in-line the Princess of Cabodia: Dayanara!”
This auction was insane, all six omegas before you all sold from a price that ranged from 198 hundred million to the one right before you who sold for one billion dollars. You were a prideful omega, and you saw worth to your abilities, smell, and looks, but were you even worth anywhere in that range?
The entire time you had been set up in who knows what, the small, overwhelming pound of your heat sinking into the depths and pores of your body was becoming heavy. You couldn’t move a single muscle still, your body still refusing to respond to the call of your body, but the seep of your slick running down the innards of your thighs, undoubtedly beginning to pool on the ground, must be embarrassing of you.
Suddenly someone spread the skin below your ass out, and you couldn’t react as something sharp and prick stabbed into your flesh. You howled in the surprising pain, and you were fast to find that whatever they had injected you with had allowed systematic movement within your body. Your eyes fluttered open as two, impossibly huge alphas grabbed you by your forearm and hoisted you to your feet.
Your neck was far too weak to carry the weight of your head, so your eyes were transfixed on the white silk of the slutty dress they dressed you in. It showed off your cleavage with no regret, and by the feel and look of it, it barely passed the bottom of your ass. Your vision swam, the alphas all over the room distorted and melting within one another as you stepped onto a stage, the spotlight on you feeling deliriously hot and melting your skin.
Your hormones, already going crazy with your heat, seemed to intensify at the small of so many capable, potent, possessive alpha pheromones that suffocated the room. Handcuffs slapped onto your wrists, and you moaned pathetically at the sting of cold metal on your skin, and you obediently followed the command of one alpha to go on your knees.
A nail slammed between the metal links of the handcuffs, practically stapling you to the wooden floor, and you whimpered at the feeling of a stuffed pillow mount being placed beneath your lower stomach. You were in a forced and easily accessible mating position with your slick and cunt exposed for all the alphas to re-smell and see.
Moaning, you shifted against the mount, your body not able to have the full movement you needed to ward off that building, insufferable heat in your core, but nothing you could do seemed to satisfy it.
“And for our biggest prize of the night, we have the one, the only, the beautiful sensation Y/l/n Y/n!” the auctioneer roared. His voice echoing in your ear as he walked over to you, exposing your dripping cunt to the crowd of alphas who had all gotten a sweet taste of your essence already. His hand came down to slap your ass with a chuckle. “Where do we start the bidding on this one, alphas? She needs no introduction, and none of you better be pussies because we know this bitch of an omega won’t take any tiny cocks as her alpha! She needs to be broken in, fucked to submission. No one likes a trailblazer… someone needs to remind of what fucking trail she’s supposed to be on. Besides, the bitch is in fucking heat, and if you don’t claim her, I just might do it myself!”
“75 million!” someone started the bidding.
You stiffened.
“75 to the man in the back!”
“90 million!” someone challenged.
“We’re up to 90!”
“125 million!”
“Do I hear another offer?”
“250 million!”
“250 million!”
The number climbed and climbed, the same voices coming to challenge each other until finally, they rounded out to a quantity that sounded bizarre even to you.
“950 million!”
If it had been possible for your knees to give out, you would have been collapsed onto the floor, the pool of slick that continued to lubricate your cunt without a doubt drowning you as you craved the need to be fucked by someone with undoubted alpha pheromones and cock in this room.
“950 million?” the auctioneer repeated, his voice for sure carrying a shark-like grin. “Going once, going twice—”
“Five billion.”
The gasp in the crowd was undeniable, and the omega in you crooned, knowing that this alpha valued you and your omega to be the price of five billion US dollars.
“Fuck!” screamed the man who had presented the 950 million deal.
“Wowee, five billion dollars, everyone! Anyone think they can beat that?! Going once! Going twice!” The crowd remained in silence, and you shook against your restraint, the heat emitting from your cunt almost demanding to be seen and fucked through this heat week. “SOLD! The virgin celebrity, Y/l/n Y/n sold to our own Shigaraki Tomura!”
The cheers of amaze weren’t nearly as loud as the smell of reeking petty alpha.
“Come and pay up, alpha, and then you can show us… a demonstration of how you’re going to break this omega.”
“Shut up.” Shigaraku growled, his footsteps heavy in your ear as you feel him climb up the stage, and you weakly tilted your head to look at the white-haired alpha boss hand over a simple credit card before walking over to you, his eyes unreadable as he looked you dead in the eye.
He reached out a finger that raised your chin up for him to study your face, moving and tilting your head as he pleased as a small, sinister smile pressed to his lips as he dropped your head. A sharp, uncomfortable pain fell on your chin as it crashed to the floor, and you shivered at the feeling of his calloused and rough fingers running down your exposed back.
“You’re such a small omega, still stupidly tiny. I bet you’ve never thought your first knot would come from someone like me,” Shigaraki laughed, his fingers and voice ice cold. His words were soft, spoken in a way that had your omega stupidly cooing for having secret conversations with your alpha who promised to fuck you till you were carrying a litter of pups. “I hope you realize that this is real life, that I will break you, and no hero in this world will be able to fucking save you.”
“Fuck the omega!” someone from the crowd screamed, and Shigaraki glared upwards. Still, you shivered in the thought of this alpha who spent five billion dollars to make you his claiming you, fucking your stupid heat brain into mush in front of these smaller, irrelevant alphas.
“I’ll do what I fucking please,” Shigaraki snapped, but the fingers you remembered to have been the last ones to enter your slicked crazy walls seemed to be his. They moved deep within you, curling and spreading your tight, sopping wet cavern apart, letting your pathetic, chirping cries echo powerfully in the room as lusting, near rutting alpha pheromones filled the room. “For fucks sake, omega, your pussy’s fucking tight as shit! Don’t you have any real knotted toys?”
You couldn’t respond back, your body on the road to a complete shut down at the feeling of something other than silicone deep within your body, fingering and dragging against your pheromone soaked walls.
“Alpha, y-your fingers feel so good!” you gasp, your hips thrusting backward, enjoying the way his fingernails press onto your warm velvet walls. “So good, you make me feel so good already.”
“I’ve seen you all over the news,” Shigaraki growled low into your ear. “Talking about how you didn’t want an alpha, how you never needed to feel the tightness that a fat knot could bring you, and look at you now. I’ve barely touched you, barely begun to make you mine, and yet you’re already begging for me, omega.”
Your arms tug at the handcuffs, pathetically wanting them off. Exasperatedly seeking more friction from your newly bought alpha. You can’t think straight, can’t come up with a single response except the stupid apologetic, “I’m so sorry alpha, I didn’t know i-it would be y-you!”
“Don’t be shy on her, Shigaraki! Fuck the slutty omega already! Fucking knot and claim her in front of us, I want to hear the omega whore scream. It’s always hotter when it’s the first claim ever!”
“You better learn how to shut the fuck up, or I’ll kill you for interrupting my fucking session here,” Shigaraki seethed, his red, smoldering eyes ripping from yours and glaring at some loser alpha behind you. You couldn’t care. You only wanted what looked like the growing cock in Shigaraki’s pants; you wanted to feel the cock fill up your cunt, and his knot to lock you both in place.
You drooled at the thought, your loud, whimpering cries unable to keep from pouring out as the slick from your core seemed to pour endlessly from your pussy, demanding attention and a knot. “Breed me, fill me with your pups,” you begged fingers taking in his dirty fingers in your mouth, tongue wildly and uncontrollably flicking across his fingers in hopes it would be a sinking prayer of your promise to be good. “I want your knot, alpha, I want these stupid alphas to know you’re so much better than them~!”
Shigaraki’s once snarl fell when he looked at you, a slowly growing smirk falling on his face as his lips spread into a cruel smirk, one that had you moaning around his fingers as he pinched the pink muscle in your mouth before disappearing before you.
“I smelled your distress when I put my fingers up your sloppy little cunt right before the auction happened; I could tell even with your growing heat that you hated the feeling of my fingers up your pretty pussy. But look at you now, I haven’t even set you on my goddamn knot, haven’t stretched that tiny cunt to its max. You’re smelling better than a bitch in heat,” Shigaraki growled in your ear. His clothed chest pressing deliriously into your exposed back, the huge cock outline in his pants grinding incessantly into your wet core, undoubtedly leaving a damp patch where his cock ground into you. “You’re an actress, aren’t you, little omega? I bet you just needed this audience cheering your name to break your mind over this. How. Pathetic.”
And the pressure on your tongue is gone, the drool and saliva sticky and cold on your chin as you whimper for your alpha. You promised that it wasn’t right, it was just that you had been scared before, but your alpha was so strong, his pheromones so scary and mean, he could protect you and fill you up with so many pups you couldn’t help but to be excited now.
The smell of Shigaraki seemed to brighten, and you moaned when his hands pressed the white dress up, allowing for your naked ass to be seen by him and everyone who stayed to watch. Shigaraki squeezed your asscheeks away, chuckling at the way your small asshole clenched in your embarrassment and pain at how your hormone-driven heat demanded that he fuck you and knot you now.
“So fucking wet,” Shigaraki observed, his fingertips tracing the slick on your folds before a small pop told you that he licked you clean from his fingers. “Such sweet slick too, you really are a prime omega, little one.”
You whimpered, ass shaking for him to continue to touch you, to continue to fuck you more.
“I don’t think you’re ready for my knot, precious omega,” Shigaraki taunted, and his words were a sealing deal in your lusting mind. Your hips knocking backward in some sort of desperation for more.
“She won’t,” commented the auctioneer.
“I will!” you scream, eyes filled with painful tears that could only be resolved with your alphas knot and claim. “I can take your knot, alpha!”
Shigaraki makes a small noise, and you choke at the feeling of something huge, nearly monstrous, shift into your cunt. You were a virgin, but even you knew that it was merely the head of his alpha thick cock, not enough for you to be satisfied, not far enough in you to breed or fuck you properly. All the moans in your throat were slightly painful, and the tears in your eyes continued to fall as you rocked your hips backward, trying to sink yourself further on his cock, wanting him deep in your womb.
You craved him.
“Ah, good, you can take more,” came the airy, almost insane driven coo of Shigaraki, the lack of humor making your cunt flutter against his thick, long cock. “Cry for your alpha, little omega.”
With that, Shigaraki slammed into you with no mercy, his cock bottoming out into you with a powerful, edging thrust. You screamed in pain, tears leaking from your eyes, and even with the pool of lubricating slick, his cock was far too big, incredibly thick that you felt your inner walls splitting in two as he fucked you as if you weren’t in delirious pain.
Drool and tears covered your arms, your painted fingers digging into the floorboards with crazy strength that you clawed scars on the floor as Shigaraki rutted deep within you.
Shigaraki commanded you with every thrust he gave, and soon the omega in you was cooing, howling for more, the pain of having your virginity ripped from right under you having become bubbling, glowing pleasure. You screamed in pleasure, Shigaraki grabbing onto your rolling hips to slam you back onto his cock, allowing for his thick cock to hit deep within you over and over again. The angle and power he possessed with every thrust were almost inhumane, nothing your lonely heat filled nights could ever dream of recreating ever. Shrill moans and pleas drowned out the annoying commentary of your onlookers, Shigaraki’s chest still flushed against your back, his hips landing heavily on your ass that was at this point raised because of the mount beneath you.
“My alpha,” you babble, eyes unfocused, hazy, and incredibly heavy as you stared at some point on the wall, overwhelmed with the feeling of Shigaraki’s hot cock pounding in you. “My alpha, such a good alpha. His cock is making my tummy feel funny, making my pussy feel so tight. Please fill me with your children, I’ll be a good omega to you and them, I promise! I promise — I — oh myyy goddd — I promise, alpha!!!”
Shigaraki puffs up with the praise, but he continued to fuck into you roughly, mercilessly, as if you were nothing more than the breeding whore omega that he had purchased you for. The wet slaps and satisfying squelches rang in the blazing heat room, the smell of the pleasured and heat insane omega saturating deeply within his nose, and in the other's nose, the prideful smell of a satisfied alpha.
Your spongy walls clenched and spasmed against his penetrating, pounding cock, sometimes even forcibly because, by god, it was hot when his cock would twitch within your womb, especially against your cervix.
“Fuck, you’re so damn annoying,” Shigaraki snarled into your ear, his teeth biting and scraping along your neck, and you wailed when his teeth dragged over the sweet scent gland on your neck. The one and only place for mating bites to go. His hand gripped your hair, tugging your head back so that you could feel his rough facial skin rub up against yours. “If you want me to fill you with my pups, you better be the best fucking omega on this goddamn planet.”
“I can be the best! I’ll be the best!” you cried, your ass shifting backward to meet his drilling hips.
The delirious sensation of his cock rocking against your cervix slowly begins to inflate the knot on his cock, restricting his still barbaric thrusting as he made to move faster. He wanted you to cum before he knotted entirely within you.
The pressure in your stomach is scorching and impossibly tight, and he takes another long stripe at your scent gland. You tremble with need, your fingers tearing into the wooden floors. You can feel the knot on his cock swelling up, catching onto the opening of your cunt with every successive cunt, and you begin to cry, shake, and tremble as the knot becomes too big.
Your eyes cross, your tongue falling out of your mouth as you babble his name. Your walls clamp around his knotted cock with the ferocity of a vice, and your body jerks violently as you cum hard around his cock. The slick essence of your orgasm slipping out of the few lasting places open before Shigaraki’s knot fills you out entirely. Despite his cock unable to move, the swollenness of his knot preventing him from moving out of you, Shigaraki still shoves his weight into his hips, the inflated knot stretching your cock out so widely, your vision went white, and you came yet a second time.
A small pop was heard, and suddenly with a rush of thick, hot, and heavy white cum exploded within your womb, his teeth sink around your scent gland, marking you — mating you. He filled you, filled you, and filled you. His cum wouldn’t stop until your belly was swollen with his hot cum, and he eventually fell off of you with a shaky, shallow breath.
You still remained on the mount, your eyes unfocused, breaths mumbling to your alpha, a promise to carry out every single pup he gave you and would give you. You were his omega, his good little omega, and you would never disappoint your alpha. Not now, not ever.

The next week, you opened your door with a broad smile, your usual clothes replaced with a dress Shigaraki had picked for you and a frilly white apron on as your agent was standing outside of your house, eyes wide, mouth gaped at the still bleeding mate wound on your shoulder.
“Ah, how funny!” you laughed, waving your hand as you sighed dreamily, your eyes fluttering at the thought of your alpha who was on a business call right now. “I’m actually going to be quitting! My alpha and I have many plans right now, I gotta produce as many litters as I can, being an actress would never give me this sort of meaning in life!”
“B-But, you’re doing so much?! You have so much to do! You can’t give up?!”
“Oh, my love, we both know that I look much cuter with a pregnant belly! Don’t worry,” you smile, taking your agent's hand, brightly smiling at her one last time. “I’m sure all omegas will eventually find their alpha so they won’t be so depressed and angry like I was!”
Your agent doesn’t get another word in.
You slam the door in her face, your hands already resting on your belly that you knew was already growing the life of your first litter of pups. It had been known the second Shigaraki filled you up anymore.
You were a good little omega, and your alpha needed you!
