Author's Note: Ohhhhkaayyy so this has been sitting in my google doc for AGES. I think I started this in...October of last year? It's been sitting there for months and I've lacked the motivation to finish and post it but then I sent in an anon ask to @reinawritesbnha and, being the absolute queen she is, she became the little push I needed to do it. I DID IT FOR REINA!!

Also, this is some of my earliest writing and I only skimmed and edited a little bit of it so if there's a little bit of weird pacing or a strange cutoff where the writing styles clash it's because I haven't touched this piece in months.

Anywho, enjoy~

It had to happen when you were surrounded by alphas.

Your suppressants flaked out, again, and your scent wafted through the air on the street. Normally It’d be fine for an omega to let their scent float freely around them. But your scent is particularly...potent, even when you weren’t in heat. Not only that, but you weren’t mated yet, your scent glands still bare, and you still didn’t have a pack. To make matters worse, you’re quirkless.

You hadn’t realised what was happening until your path was blocked by an especially large male alpha. You turned around, and there were two more behind you. Fuck. This isn’t good. You took in your surroundings and searched for an exit, but you couldn’t find a way out. There's no way you’d be able to outrun the three very large male alphas.

Probably the worst part is that more alphas are turning their head toward you, taking notice of your lavender honey and rain scent that slowly began turning to a sour swamp. You dared to hope that change would ward off the three cornering you, but they’d already got a whiff of you. Several distressed chirps sounded from your chest, voicing your discomfort, and you glared pointedly at the three alphas as they edged closer to you.

You hate when this happened. Why’d you have to be cursed like this? Your growls only grew, baring your little omega fangs. There’s no way in hell you’d let some stranger scent you, let alone one of these creeps. They wouldn’t take the damn hint and just crept closer to you, calling out to the ‘pretty little omega’ to ‘come have some fun’.

You’re scared now, the involuntary chirps in your chest coming more frequently. None of the other alphas or betas on the street were big enough to face the three, making you a sitting duck and a ragdoll if they wanted you to be. Your claws are small, nowhere near ideal for this situation, but you’d use them if you needed to. With a final low defiant growl you dropped your bag against the wall behind you and readied yourself for a fight.

Suddenly a large body dropped in front of you, his back to you. His scent alone hit you like a freight train, orange zest, mint, tree bark and something earthy. It had your head spinning, nearly sending you into an early heat. He growled, low and powerful, the sound rattling in your chest and making you sink further into the wall behind you. The other three alpha’s scents together were still overpowered by the new alpha before you, and they vanished faster than they appeared.

He turned around and stepped away from you, giving you space to breathe. He kneeled down enough so he was eye level with you, his hands reaching out clearly in an attempt to comfort you, but kept from touching you.

“Are you okay?” The question barely registered, still delirious from his scent, and you’re having a hard time recovering. Large hands grip your shoulders and shake you lightly, your mind beginning to clear with the soothing pheromones he’s releasing.

“Omega.” The command snapped you to attention, your gaze fixated on his own dark irises.

“Are you okay, omega?” You blink, swallow down the lump in your throat, take a deep breath.

“Yeah...I’m okay. Thank you, alpha.” But you’re not quite okay. You need to get home. Fast. The alpha seemed to catch on, probably by your scent that still hadn’t returned to normal. He stands and slips off his jacket, draping it over your shoulders and wrapping you in his scent. It’s a comforting gesture.

“Let’s get you home.” With a nod you set off, the man walking next to you with a strong, warm hand on the middle of your back.

“What’s your name?” You introduce yourself, and he does the same. His name is Sero Hanta, and now that you’re calm again, you take in just how handsome he is.

Raven hair is pulled back into a small bun, showing off his undercut and strong, sharp jawline. Onyx eyes shine with kindness and playful mischief, and a beaming grin reveals pearly white teeth. He’s incredibly toned, his muscles calmly rippling under the t-shirt that stretched over his chest. You vaguely noticed the strange shape of his elbows, but disregarded it as his quirk. The omega in you is howling, begging for this alpha, his scent invading your senses. But you suppress it quickly, reminding yourself you’d only just met this man.

As you reach your apartment you exchange phone numbers, and he tells you to keep the jacket and use it when you go out to ward off any unwanted attention. You thank him again for helping you earlier, and he waves to you as he walks down the hall and enters the elevator, the doors closing in front of his handsome smiling face.

Despite meeting him only ten minutes earlier your instincts trust the alpha, and you hold the jacket close to your face, breathing in his scent. It’s wonderful, and your inner omega is in love. You find yourself wondering when you’d see him again.

The next few days are riddled with work and calls to your doctor about the strength of your suppressants. You work from home as a secretary for a small company. It’s a miracle you’d found it, too. Nobody wants an omega, let alone a potent one. It’s an alpha’s world, you guess. When this job opening popped up you were ecstatic, so you took it and have been working from home with decent pay for the last five years.

The calls to your doctor were not going as smoothly as your job, though. You leave a message every four hours until she finally calls you back. She was concerned since the suppressants she’d prescribed are the strongest out there, and if your scent was overpowering them they were either defective or your scent glands were overproducing. It wasn’t an immediate threat to your health, it only meant you’d be drawing more attention than you wanted to. Still, it’s annoying and makes life so much harder than it needs to be.

After she prescribed twice the amount, she said she’d look over your tests from the latest visit before she hung up the phone. You groaned once the call ended. You seriously needed a break from your second gender. Taking the prescribed double dose of suppressants, you got ready to go out to the corner cafe to read and drink coffee. Hopefully the new amount will keep steady. You really don’t want to deal with any more aggressive alphas this week. For good measure you pull on Sero’s jacket, allowing his scent to cover you, then grab your keys, phone, wallet and a book and begin the walk.

When you arrive at the cafe you order a hot mocha, curl into the small corner booth and crack open the book. You got lost in the ink and your mind floated along the adventure, putting yourself in the shoes of the main character and leading the mission to take down the corrupt queen who’d framed you for killing the prince of a neighboring kingdom. You were ripped from the fantasy world when a bright, enthusiastic blonde came up and tapped you on the shoulder, making you jump. His smile was as bright as his hair.

“Sorry to scare you cutie, but I couldn’t help but notice that jacket of yours smells an awful lot like my friend Sero!” You smile softly at the blonde.

“Well if we’re talking about the same Sero Hanta, then your nose would be correct. This is his jacket.” His eyes widen as he nods.

“Oh my gosh you must be the omega he keeps talk-” The blonde’s words became muffled by a large hand. A hand that belonged to the very man you were talking about. Sero smiles apologetically down at you as he shoves the blonde back to where you assume they’re sitting.

“Sorry about Kami, he’s… extroverted.” You smile back at him, mostly because you’re happy to see him again.

“It’s no problem at all. He recognized your scent on me.” He looked down and only then realized you’re wearing his jacket, and he beams at you. Then he takes a glance at the booth you’re sitting all alone at, his smile falling just a bit.

“Do you wanna come sit with us?” You take a moment to think about the offer, then agree with a nod. Your omega couldn’t pass up more time with him.

As you approach the booth you notice there are more people with Sero than you anticipated. There were four other people sitting there. Sero introduced all of them from left to right. Bakugo Katsuki, Kirishima Eijiro, Ashido Mina, and the happy blonde from earlier is Kaminari Denki. You introduce yourself and when Sero slid into the booth, you followed after him.

These five are a tight pack, and you learn they all met in high school. Bakugo’s brash personality made you wary at first, but it didn’t take long to realize he’s just like that with everyone. He makes a bit of a snippy remark, which you easily counter, and he smirks while the rest smile or snicker. It would seem they like you.

You can’t tell what their second genders are, and you mentally kick yourself for even wondering in the first place. Their genders are none of your concern, but you can’t blame yourself when you’re constantly alert because of your own stupid second gender. As it turns out, you don’t need to wait very long to find out.

This time you smell your own scent as it permeates the air around you. You swear under your breath at the stupid suppressants that obviously can’t so their job, and the others snap their gazes to you. You sigh.

“Yeah, that scent is me. My suppressants flaked again. Sorry about that.” They all nodded, seemingly understanding. Sero must have told them about the other day. Of course, it would soon repeat. It didn’t take long for an alpha to take notice of your scent. The man -- why is it always the largest males??? -- strides up to the booth with a cocksure grin and leans down to inhale your scent. You duck away from him, into Sero, and let out an albeit small warning growl that was drowned in Sero and Kirishima’s. He ignored them all the same.

“Hey there little omega, you smell real nice. You wanna come hang with me instead? We can have some fun together with my buddies, what do you say?” The others stayed quiet. They’re going to let you defend yourself before they do anything in case they end up escalating the situation. You turn your head and lift your shoulder, hiding your scent gland.

“I’m not interested, thank you. Please leave me alone.” You hoped to whatever deity watched over you that the man would leave. Before anyone could react the alpha grabbed your wrist in a vice grip, yanking you roughly from your seat. You chirp, your scent turning sour and the entire pack abruptly stands, baring their fangs at the man. It barely registered in your head that Kirishima and Bakugo are alphas, Mina is a beta, and Kaminari is an omega, their fangs giving them away.

The man tightens his grip on your wrist and you cry out, your bones creaking under the pressure. With no other options you did the one thing that would get him to let go, and sank your fangs into his wrist. You jump back into Sero, who wraps an arm around you protectively.

“You bit me, you bitch!” He raises an arm, clearly about to try and hit you, but a large hand grabs his wrist. Surprisingly enough it’s Bakugo, and his growl is laced into his words.

“Leave now, or you lose a hand.” Sero speaks up from above you.

“You might wanna listen, amigo. That’s Dynamight.” The alpha rips his arm from Bakugo’s hold and looks down at you, and you growl at him as he scoffs and walks away, apparently not ready to fight the #2 pro hero over an omega.

You all sit back down and you pull up the sleeve of the jacket to inspect the already forming bruise on your wrist. Your nose wrinkles with a half-angry half-pained snarl. Tenderly, Sero takes your wrist and lightly squeezes the sides of your forearm, against your bones, and your lack of reaction tells him nothing’s broken. Still, he growls at the offending bruise.

“I’m gonna kill him.” You shake your head and put a hand over his.

“It’s not worth it Sero. He’s probably long gone.” You turn to the rest of the pack.

“Thank you for protecting me.” Kirishima is the first to speak.

“Of course! That dude was a jerk. I just hope he doesn’t go around doing that to other omegas.” Bakugo, surprisingly, spoke next.

“Obviously we’d protect you. You’re a potent omega and quirkless, so you attract unwanted attention without even knowing or wanting to. Besides, if you’re gonna be Sero’s omega there’s no way in hell we’d let some extra handle you like that.” The implications make your face burn, and Kirishima smacks the blonde’s arm with a ‘Don’t just say that kind of thing, Katsuki.’

After an hour or two of talking, and shockingly no other aggressive alphas, they all walk you home to your apartment. Sero wanted to check on your wrist again, so you invited them all in, but they all had something else to do, so you were left alone with Sero. The fact that the one alpha you desperately wanted to be around is alone with you in your apartment is both great and terrible. Thankfully, you have self-control and his own suppressants are working perfectly fine.

He inspected the darkening bruise on your wrist, his large hands gripping your arm tenderly and turning it gently as he prods at the skin. It doesn’t hurt too bad, so you assure him you’ll be perfectly fine. Eventually he leaves with a hug and you sigh once the door is closed, relieved that you were able to keep your omega at bay and your hands to yourself.

A couple days later you get a text from him and the two of you text often, asking how each other’s day went, if anything interesting had happened. You didn’t leave your apartment unless you needed to, since your suppressants clearly weren’t working, so you made sure to cut grocery trips short and keep away from any alphas that seemed a bit aggressive. Sero invited you to hang out with the pack at their house, and you obliged.

They lived in a huge house all together. Most of the rooms were sealed so no scents or sounds could go in or out for ruts and heats, and there were several spare rooms that were empty and waiting for more pack members. It was a fun hangout, filled with video games and good conversation, and even better food which Bakugo cooked. Sero had an arm around you whenever he was close, and you definitely didn’t mind. Your suppressants flaked in the middle, again, and Sero insisted he walk you home. With him walking you home there weren’t any alphas trying to get you this time. You ended up going over to hang out with them a lot when you weren’t working, and eventually Sero began to court you.

Obviously, you accepted, and after a few months of dating and scenting, your overactive scent glands seemed to mellow out, Sero’s scent mixing with it. Your suppressants are lasting much longer now, which is a good sign. Now that you’re Sero’s omega, he often helped you with your heats and you’d help him with his ruts, and he was strong-willed enough that he hadn’t marked or knotted you in the middle of things.

About a year and a half into the relationship you realize you really love him. Sure you had arguments, but everything was settled through calmed discussions over coffee or tea, and you came to understand each other well enough that arguments became few and far between.

You’re happy with Sero, so when your heat came around early and he was there to help, you were going to let him know just how much you loved him.

You texted him once you felt it starting. He was there within half an hour, and you pounced on him once the font door closed, smothering him in hot, wet kisses, eager to feel him inside you. He carries you to the bedroom, and you two are quick in shedding all of your clothes. He lays you on your back with a hand on your throat as he growls into your ear, making a hot shudder roll down your spine.

“Are you ready for me omega?” You whine and nod, your slick already dripping down your folds. You want him so bad it hurts.

“Please alpha, I need your cock.” He growls again, satisfied with your answer, and he presses into you, bottoming out with one firm thrust. You chant his name like a mantra as he set a bruising pace, rutting into you recklessly, wet skin slapping on skin the only other sound beside your whimpers and his growls. His teeth nip at your shoulder, sharp fangs testing your skin and claws digging into the fat of your hips. His cock is so deep, hot swollen tip kissing your cervix with every full-bodied thrust and sending you into a euphoric haze. Your own claws are sinking into his back, leaving little trails of red and blood beading down the lines. It drives him wild every time.

“That’s right, little omega. Mark me up, I’m all yours. Fuck you’re so pretty underneath me like this.” His hands grip behind your knees and press them into your chest, folding you nearly in half as he plows into you further. The angle knocks the breath from your lungs and your eyes roll back. You can feel his knot beginning to swell, feel how his thrusts are getting more controlled and his grip on your thighs tighten from the sheer concentration it’s taking for him not to breed you. You have other plans. Between wheezed breaths you squeak out.

“H-hantaaa~” He slows to a near snail’s pace, grinding his slowly growing cock into your sweet spot, a smirk stretching across his face as you splutter from the sudden change. He’s enjoying making you squirm.

“What is it, sweetness? Tell your alpha what you need.” You pant, chest heaving as much as the position will allow.

“Want your mark, want your knot~ Wanna be bred Hanta! I want your pups!” He stills completely, claws digging into the fat of your thighs with enough force to have drops of blood falling to the sheets beneath you. You’d never said anything like that in the heat of the moment. He can’t have heard you correctly...right?

“Princesa, do you know what you just said?” The seriousness in his tone has you sobering, but even before you knew exactly what you were saying. You nod frantically, wiggling your hips to get him to move again.

“Yes! I know alpha! Please, give me your knot~” His growl makes your bones shake, and with no warning he drops your legs around his waist and leans down so his face is buried in your neck.

“Fuck, I’m gonna trust you with this baby girl. I’ll give you exactly what you want.” His fangs sink into your scent gland just as he picks up his brutal pace, and the euphoria makes you cum hard, your whole body locking up and mouth falling open in a silent scream. He plows into you as you regain your breath, and you bite down on his own scent gland as hard as you can, tearing into his skin with every intention of leaving a pretty scar for the world to see.

His knot swells more, and he’s pushing it into you with every ounce of power he can generate with that gorgeous body of his. With one final snap of his hips he locks his body to yours and cums hard, ropes of hot seed filling you to the brim. He collapses on top of you and laps at the wound on your neck and you do the same. After a few minutes he leans back and cups your face in his hand, gazing down at you like you hung the moon and the stars.

“Are you alright?” You nod, nuzzling into his palm.

“I’m sorry. I was gonna talk to you about it, but my heat came early.” He kisses your forehead gently, brushing the strands of hair from your face.

“It’s okay, pretty thing. I trust you know what you’re getting yourself into.” You giggle and wrap your arms around him.

“Of course I do. I love you, Hanta.”

“I love you too.” You lay there, tangled in each other’s arms until his knot goes down. You whine at the loss when his cock slips out of you, clawing at him to come back because you’re still in heat. His hand gently wraps around your neck, a low chuckle on his lips.

“Relax, we’re far from done.” His already hard erection rubs up and down your glistening folds, barely stimulating your clit, teasing you until tears prick your eyes and you’re beggin him to fuck you again.

“When I’m done you won’t be able to walk for days. I’m gonna breed you so well, You’re gonna look so pretty all big and round with my pups.” He groans at the image he’d conjured in his head and you squeal as he slams his hips into you.

You’re in for a wonderfully long night.
