Work Text:
Ochako had very limited knowledge on what being an omega meant. When she signed up for UA, all she knew was that she had to be careful - especially when out on patrol. But she was in high school - she was on suppressants and she was working towards being a hero. That was all she cared about.
It was probably why things ended up this way, the three of them in her bed on their sides, panting after what they had just done. Katsuki stuck in place, his face in her chest as he panted to get his breath back, and Shoto stretching her wide and his shaking exhale hitting the back of her neck.
This was going to be a hard thing to explain.
~*~*~
In their third year, the UA students had been through a lot - they’d won and lost battles, gotten better and made their way through to the top. Their futures were looking bright, and any position was theirs if they only wanted it.
Amongst their grade, it was a surprise when the top three became the top four. With Deku becoming a hero that almost all the public recognised, it was clear that he would be in the top three. Bakugou was amongst the top in both grades and skills, and the same went for Todoroki. Yet, when the school realised the top three of their year, there was a general consensus that it would result in one or more of them killing the other. Two alphas and a beta were bound to end up killing each other in some way.
So to calm the hotheaded alphas and stop the beta from suffocating the first years with his overall knowledge on...well, everything superhero, Ochako was asked to help. It wasn’t like she would be fourth in their class, but she was determined enough to be that way. Ochako somehow eased the tension of the group, and she was the perfect spokesperson to not scare the living shit out of everyone. She was seen as determined, and when it came time to demonstrate with the first years, the two sides of Ochako collided.
Sure, Bakugou was terrifying. But when Ochako smiled like she could crush everyone in that class without blinking, it did leave an impression.
In all, it was safe to say that the top four became close. Not like Bakugou could be close to anyone, but he did help Ochako study to keep her position most of the time, but Ochako had always got on with Deku, and Todoroki was always fun to talk with when he was feeling talkative.
During one of their breaks, some going off to experience their heats off campus, or go home to visit family, Ochako stayed at UA. It was easier than going home - she was just another mouth to feed, and she could live with whatever the school supplied. Among the few that stayed were Bakugou and Todoroki. Mina stayed as well, but she was off campus for a majority of the time - her new internship took up most of her time now, but she was excited that an agency was willing to take on an Omega so early. Everyone else was gone.
Bakugou stayed to study for their final exams, and Todoroki stayed because it was better than going home where his dad was. Over the years Ochako had learnt many things about the boys - that Bakugou had a peaceful side that only few had seen, that Todoroki was far more caring than his upbringing would let on.
“How’s the internship with your dad?” Ochako asked one night, the three of them sitting in the common room.
“He’s trying too hard, it’s annoying,” Todoroki replied.
“That why you’re staying here instead of going home to see your damn sister,” Bakugou huffed, throwing one of the couch cushions across the coffee table at Todoroki, “she fucking worries about you,” he reminded. Though, as Ochako looked back at him, she had doubts that he needed reminding.
“You’re only saying that because she made your dinner extra spicy,” Todoroki replied, throwing the cushion right back.
“Fuyumi deserves better than you fuckers,” Bakugou grumbled.
“I do hope she’s doing well,” Ochako giggled, shifting to sit cross legged on the couch. Todoroki smiled one of his very rare smiles at her, tilting his head as he took her in. Sometimes, in their very rare moments, Ochako found that whenever certain alphas looked at her, she got girly.
Todoroki was one - his eyes, their grey and blues looking at her made her stomach do flips and something far more primal was in the place of friendship. Bakugou was another - his gaze always burned, regardless of her time of the month. His smile, however, made her feel like a puddle - sopping wet and ready to be stepped on. Admittedly, she felt that the most around the time when she was supposed to be going into heat, but he did have a nice smile.
“She asks about you sometimes,” he confessed, “gets worried that you’re one of the only Omegas around UA,” he said, looking back at his hands, as though he were embarrassed to have brought it up in the first place.
“It isn’t like I’m a rare breed,” she shrugged. Omegas weren’t endangered or anything, there were just fewer than there used to be. It was more uncommon to be quirkless than to be an omega, but Ochako didn’t care much about being an omega. There was never a reason to worry.
“It’s rare for a hero. Most heros are either betas or alphas,” Todoroki reminded, to which Bakugou grunted in agreement.
“It’s never been an issue before, I think I’ll be fine,” Ochako said, rocking back and forth.
“What if you go into heat? You could set off every fucking alpha in your agency. Not to mention all the villains, round face,” Bakugou spat with a snarl. Ochako frowned, shaking her head. She hadn’t expected Bakugou to be so bigoted, but then again, he was an alpha.
“That’s what suppressants are for.”
“Wait, you’re on fucking suppressants?” Bakugou snapped back and Ochako frowned, nodding back to him.
“Of course I am, you really think I can walk around campus with your lot around?” she laughed.
“What about your heats?”
“I wouldn’t even know what one felt like. I get more feeling from my period than I do from a heat, it usually passes before I even register it could come,” she explained.
“Makes sense, I’ve never smelt you before, even though you’re well past your presenting heat,” Todoroki said, holding his chin as though he were only just realising everything in that moment.
“That was such an awkward week. The alphas were all so clingy around me,” she shivered, thinking about it. The attention was unwanted and after the first day, she realised what was happening. Presenting heats could last from anything from a few hours to a full week, almost mimicking the real thing.
“You had your presenting heat here?” Bakugou asked.
“You’re being really invasive,” she said defensively, “but if you have to know, yes, I had it here. You were one of the alphas,” she reminded.
“What?”
“When you’re on suppressants as an omega, going through your presenting heat is a little different than actually going through heats - as I’m told. Like that entire week I was horny as hell,” she giggled, knowing her cheeks were far more red than their usual pink, “and just felt like everyone was showing off for no reason. All the alphas could sense there was something wrong, and tried to be close. Like you, Bakugou, you would walk beside me when you hadn’t before, and Todoroki, you ate lunch with me for that entire week but I don’t think you even noticed.”
“Who else?” Bakugou suddenly growled.
“Well,” Ochako pondered, “Sero for one, he wanted to study together every day, and Shinso even tried to see me a few times. Even asked me out until I told him what was happening,” she explained, before the end of that week popped into her mind. “Oh! And Kirishima kissed me!”
“What?!” Both alphas shouted, shocking Ochako back into the couch.
“Yeah, he kissed me, and he didn’t realise what he’d done until he looked at me after. He was in so much shock he apologised and didn’t look at me for a week,” she laughed, rubbing the side of her neck. She knew she was covering up her scent gland, but something in her told her to do it - to not be so exposed at that moment. “I had to tell him about the heat so he wouldn’t feel so bad.”
“When the hell was this?”
“Oh? End of first year?” she shrugged.
“Wasn’t he going out with Mina then?” Todoroki remembered.
“Yes, another reason he felt bad. We talked about it - all three of us - and she was ok with it. Her own heat came about a week after that.”
“Is Mina the only other Omega on campus?” Todoroki asked.
“Oh Aoyama, of course, but that’s about it,” Ochako thought. There were only two other omegas in class 3B, but they were in committed relationships - common for most omegas to be paired off young.
“I always forget about sparkly jackass,” Bakugou chuckled.
“He’s only set off Shinso and Jiro, but he’s pretty careful about everything.”
After that, the subject was dropped and they continued on with their night. It still nagged at her though - that being on suppressants bothered them so much. Ochako felt more self conscious than ever after revealing her suppressant status. It made sense, most alphas didn’t take any suppressants or concealed the fact that they were alphas. It often made days distracting. Even though their scents had no real effect on her, she could still smell them when they were going into a rut.
There were also no questions asked around this time if students were gone for a week - most likely rutting until they were done - locked into place and unable to move.
Part of Ochako knew that the two boys were experienced, their scents were the strongest to her, and often made some study periods incredibly difficult to concentrate on. They could flaunt the fact that they were fucking everything that moved - but Ochako was always so uncomfortable with going off her suppresants, the lack of control that everyone talked about was frightening.
She’d known for a long time before she presented that she was an omega. It was the little things at first - aka, she was shorter than most of her classmates. It wasn’t like she was short to any degree, but she could tell that she was a little tinier than some of her classmates. Her quirk too was something very much like an omega - it wasn’t destructive, but it had its potentials. She knew she could be a hero with it, but others would look down on her for it. Ochako asked her parents if she could get tested early, and there it was in fine print; Omega .
After that, she took precautions to stop being the weak, defenseless omega that she could become. Ochako was strong, and the fact that she was an omega made everything so much harder. It was worse that the people around her were alphas, strong and willing to go the extra mile to no extra effort - and all Ochako could do was struggle to keep up.
She went to bed that night feeling hopeless about herself - that she was nothing more than her status as an omega.
When Ochako woke up a few days later, she felt like she was itching to do something. She knew she had a lot on her plate, and with most of her class coming back in two weeks, it was just trying to decide how and when she got things done before everything became chaotic. But this was different...something was wrong. She definitely needed to have a shower, but Bakugou was meeting with her in... OH SHIT, TEN MINUTES ? How did she sleep in so late?!
She changed, went to the kitchen and made herself a quick breakfast before setting up for her study session.
One of the plus sides of being ‘friends’ with Bakugou was that he would often study with her. He’d give her feedback, albeit in the form of yelling, but it helped in the long run. As they sat in the common room, Ochako was going over her notes when she heard a distinct sound of someone sniffing. It was sharp and close. Ochako looked up to Bakugou, who had his head resting on his hand, going over his work.
“You coming down with something?” she asked. Bakugou looked up to her, a crease in his brow.
“The fuck you talking about?”
Ochako blinked, looking at him oddly. “You just...sniffed?”
“No I didn’t, get back to work.”
She shrugged, going back to work but god, did she feel like her body was going to give out. Ochako had only just woken up and here she was feeling like a goddamn mess! Her skin was on fire - like she’d been near a stove too long.
Something in her belly felt off - as though she were coming down with something. Was what Bakugou had contagious? She shifted uncomfortably before the tension waned. Tucking her hair behind her ear, she focused back on her work. It wasn’t long before she felt a similar sensation, but one that made her skin crawl - one that she needed to pay attention to.
Glancing up, she found crimson eyes burrowing into her. Onto her. It wasn’t even like Bakugou was looking at her, it was as though he were finding something on her person that he couldn’t quite make out.
“Do I have something on my face?” she asked. Bakugou snapped his eyes to hers, his cheeks suddenly heating to a red.
“Huh?”
“You keep staring at me,” she said, as though it were only just occurring to both of them once she spoke. But he didn’t say anything else. “I’m gonna go shower, we’ll get back to it when you stop being weird,” she cleared her throat, pulling all her books together and ready to leave. But before she could do anything, Bakugou grabbed her wrist, dragging himself up from the couch, his face going to the crook of her neck.
Her face was already hot enough, but when he inhaled, she felt like she’d burst from embarrassment. What the hell was he doing? But when he did it a second time, Ochako felt like her knees were going to go weak. It took everything in her to seperate them, even if it were just to look into his face.
“What’s with you?” she reacted, trying to pull away, but Bakugou’s hand was tight, only letting them part a short distance. When he finally dragged his blazing eyes to hers, he frowned - as though he were coming back to himself.
“I-I don’t know,” he grumbled, letting her wrist go. Ochako rubbed at it shortly before grabbing all her things and racing away from him. Whatever the hell Bakugou was on now, Ochako didn’t want to be around it. He was aggressive most of the time - now there was something about him that made her stomach do flips. She wasn’t sure if that was a good or bad thing.
Racing to the shower block, Ochako jumped straight into the coldest temperature it could go. Even that proved to be a fruitless endeavour. It felt like the shower was giving her the hottest water, her body like a furnace. She was probably burning up from something, but she couldn’t tell what the hell was happening.
She woke up, she had breakfast, she got changed and she gathered her things together to go study with Bakugou. Everything was pretty much the same, except for maybe...
Wait.
SHIT!
No no no no no! Fuck!
She had completely forgotten to talk to Recovery girl! Ochako thought she had more time! It was only a few days how the hell was she meant to fucking know?!
Her hand was between her thighs, the shower providing absolutely no relief whatsoever. FUCK . She turned off the spray and dried herself quickly, dressing without much grace and racing towards her room. God she probably smelled and the mounting pressure was insane. She curled herself in her bed and whimpered.
How could she have forgotten to get her damn suppressants injection?! A three month wait between injections was the exact reason Ochako kept a calendar - but with all the stress piling on her with the end of term, she’d barely noticed the days go by. That injection was one of the only things that kept her normal, and now she had a week to ride out the most uncomfortable part of her life. It was torture.
With her pillow shoved between her legs, holding onto her quilt for some form of relief, she heard footsteps outside her door. Two sets. It was clear, and brought a lingering smell that waffed inside.
“What are you doing here?” Todoroki said, voice muffled through the door.
“What are you doing here?” Bakugou bit back at him. Bakugou’s voice, compared to Todoroki’s, was not silenced at all.
“Go away!” Ochako yelled before she cried. The sound made the rage from the other side of the door simmer to fear - a painful yelp as she whimpered. It hurt. Everything hurt. Why did it hurt so badly?
“Ochako, you can’t ride this out alone! It’s going to be -”
“I know I’m in heat! I just want you both to go away!” she cried, her tears cool against her skin. Why did she feel like she was on fire? Right...heat. Fuck. Nothing made sense to her at that moment.
“Oi! Shit for brains, the only way you won’t be in fucking pain if you get one of us to help you out!”
“The hell are you -” she didn’t finish it, as she realised what he was talking about. She knew that - but why in that moment did she forget. The pressure between her legs was all the reminder that she needed. Ochako wasn’t thinking straight because her body didn’t want her to just stand, it wanted her to act.
With weak legs, she stood, staggering to the door. With a deep breath, she opened the door just a fraction. Even that proved to be fatal, the scent that wafted through was enough to have her panting on her hands and knees if she hadn’t been clutching to the door. As she stared at the boys in front of her, she wondered what she smelt like to them - her scent luring two alphas to her room in the middle of the day.
“Ochako,” Todoroki said, voice filled with concern.
“Round face, are you -” They both reached out as Ochako stumbled - if they got any closer she’d lose all sense of control and fuck them both without a second thought.
“Shut up, both of you,” she snapped, holding herself up by the knob of the door handle. “if either of you speak I think I’m gonna collapse,” she admitted, to which they both backed up.
There was silence, waiting for any form of confirmation from her. She didn’t know how to answer it - to acknowledge that she was to give in to her most primal side was like torture. As each boy huffed out a heated breath, she knew she needed to answer the silence as quickly as possible.
“What do I need to do?” she asked, tilting her chin up, as though she were going to look at them. But even doing that was making her weak - exposing the glands on her neck that obviously drew them in. She buckled, feeling their presence get far too close for her liking.
“Wait,” Todoroki said, as though he were finally realising something, “you’ve never ha-”
“I’m asking what!” she snapped. The two boys tensed - not like their authority was being challenged, but that they wanted to move
“You know what,” Bakugou replied, his voice low. Her nails gripped into the door.
“I have to...pick?”
“Who’s it gonna be?” Bakugou asked.
Ochako smelled the air, their scents lingering around one another, making it all so hard to decide. It was sweet, but tainted by something, and also….fresh snow. Everything was so clearing and fresh that she couldn’t think clearly. The decision came out before she could even think about it.
“Both of you.”
Bakugou’s face scrunched up. “The hell are you talking about?”
“I can’t choose right now, so don’t make me! On and off! One day Bakugou, the other, Todoroki,” she tried to sound out what she meant, but the ache that raced over her body was getting so intense, and having them both staring at her was not helping in the slightest. She was breathing far more heavily than she should have been.
“You have to make a decision now, though, Ochako. We can work it out once you’re down from your heat,” Todoroki told her.
Bakugou huffed, and the scent of caramel being so damn strong, she whined as she took it in.
“Bakugou,” she whined, to which he growled. Ochako took in the defeated look on the scarred face in front of her. “I’m sorry, Todoroki, I just -” Ochako didn’t get a chance to finish before Bakugou slammed the door behind him, backing her into her room.
“Don’t fucking apologise, I’m gonna share you with another fucking alpha,” he growled, his lips catching hers off guard. “Not yet anyway.” Her eyes sprung wide as he kept backing her towards the bed.
“Bakugou, you -”
“Shut up,” he replied, and Ochako found that she had to comply, “but if you call me anything, call me Katsuki,” he said, his hands going to the side of her face before he leant down and kissed her. His mouth trailed over her in no time, kissing and sucking at her skin as though she tasted like something he couldn’t quite work out yet. All the while, Ochako was seeing stars. The pain she’d suffered with was gone, and all that remained was blinding need.
As he kissed over her neck, making moans come through deep within her - the sounds she made were catching her off guard. She knew that everything he was doing to her was amplified by her own damn genetics, but it felt like he had far more power over her without even trying. It made her feel so small. Katsuki’s hands ran up her sides, slipping under her shirt, fingers so large that even grazing her nipples felt like they were taking up her entire breast. It wasn’t fair.
“Stop hitting me,” Katsuki murmured against her neck.
“What?” she panted. Katsuki stopped kissing - or was it licking? - her neck and she whimpered, missing him devouring her.
“You keep hitting me!” he snapped, gesturing down to her bound fist that had just hit his shoulder.
“I don’t...I didn’t -”
“Are you ok?” he asked, voice filled with an uncharacteristic concern. Katsuki stepped away from her, and she felt like she was burning up without him.
“I’m...I’m fine,” she stuttered, her body missing the warmth of his. She may have been burning up, but it was a strangeness, to need warmth to ease the aching burn that ran over her. It cooled her down.
“Don’t lie to me,” he said, and she couldn’t deny his words.
“I don’t want you to see me as weak...everything about being an omega makes me weaker and I won’t be a good enough hero and I’m -” he shut her up by kissing her again. She whimpered at his touch, forcing herself not to give in entirely. If she did - she’d jump straight into his arms and force him to the bed, mounting him like -
Oh god, her mind was racing - begging her to finally have him inside her. To fill her like she’d never been filled before.
“Don’t say that shit to me ever again,” he said, “it doesn’t matter that your body is fucking you over right now. You’re my fucking omega, and everything about you is goddamn perfect. Now stop hitting me and let me fuck you. I know you’re gonna make that a challenge anyway,” he smirked and Ochako chewed on her lip. That wasn’t fair at all.
“You’re not…” she started, her hands already binding into the front of his shirt, pulling it up and over his head. He stared back at her with blazing eyes. “You’re not going to look down on me for what I do, are you?” she asked cautiously.
“Only way I’m gonna look down on you is when I’m on top of you, don’t worry,” he said, sneaking her shirt up and over her head. In the rush, she only just realised that she hadn’t even put on a bra - she just wanted to go to her room. His mouth trailed down to her chest, kissing over her breasts before he took a nipple into his mouth, teeth grazing over the sensitive peak. Ochako couldn’t help but moan, and loudly at that. Cupping her hands over her mouth, she muffled the noises that were escaping her lips, only to have Katsuki’s blazing eyes staring back at her and wearing her done.
“No, you’re gonna be as loud as you can be,” he growled, pulled her hands away from her mouth as her head bent back.
“I don’t want to wait anymore,” she begged, groaning as she arched into the mattress.
“You’re a virgin, right?” Katsuki asked, his teeth snaring her nipple between his teeth.
“Yes,” she sighed, her hands grasping onto his shoulders as a way to ground herself. She felt like floating - soaring from her own body in the ecstasy of the moment, and unable to quite take hold of the world around her.
“Do you have any -” Katsuki murmured, spreading her thighs apart as he crept lower, tugging her shorts down her thighs until she was becoming completely bare beneath him.
“The kits they give us, it’s still in the -”
“Perfect. Thank fuck you’re a virgin, cause I ran out of this shit the first time I went into a rut.”
There was a pang of jealousy that raced through her. Who could dare to take him from her - who pleased Katsuki before Ochako could get her hands on him? It wasn’t fair that this was the first time she’d allowed herself to succumb to such a state - even if it was involuntary.
As Katsuki went through the kit, finding the stack of condoms that were regularly updated for all the omegas and betas on the floor, but as he glanced between her and the condom in hand, he merely smirked. Katsuki parted her legs as he sat on his haunches before he bent lower and began to lick and suck at her cunt. Ochako cried out, surprise ripping through her as his tongue worked inside her. It was easy to tell that her body was ready - without him even touching her, her slick was running down her legs and onto her mattress; Katsuki was just lapping it up.
“I could drink you for hours,” he murmured against her thighs, nipping at the tender skin there before continuing to push his tongue inside and drink.
“No, stop...don’t say things like that,” she cried, her hips jutting up to meet his mouth in spite of her words.
“Stop being so fucking delicious,” he smirked as he kept going. His hands wrapped around her thighs, locking them in place even when she wanted to close them. Ochako had never been touched like this - never thought of what it would feel like to have a mouth descending on her and playing with her clit enough to have her slick splashing up onto his cheeks. Like, seriously?! It was like she was a broken tap with the way she was streaming down onto her mattress.
“Wait, wait, wait, I -” Ochako stuttered, her hands scrambling over the bed for purchase before she clutched into his hair. Katsuki chuckled as his tongue swished and twirled over her clit, making her thighs shake and breath come in hiccuping gulps. Katsuki let her body fall back down to her bed, his hand stroking up from around her thighs up towards her stomach and fingers grazing at the puckered peak of her nipple.
Ochako reared back, her body arching from the bed as Katsuki coaxed her down, fingers running delicate lines over her body as if she were a marvel to have in his hands. Her whole body was shaking, reeling in the aftermath of pleasure as the dull ache of her heat was making her skin prickle in anticipation.
“Oi, half and half, get in here,” Katsuki suddenly shouted and Ochako sat up in her bed, elbows propping her up. When the door opened, Ochako instinctively covered herself as best as she could.
“Wh-”
“Like we’d really keep each other out,” Katsuki smirked, nipping just under her jaw - the contact making Ochako whimper and fall into him. Suddenly, he wrenched her legs down, making her fall back down to the bed. Instead of Katsuki over her, it was Shoto, his shirt discarded somewhere and his body emitting a scent that had her slipping furthering into her bed. It was a sharp peppermint with charred sandalwood, making her feel like she was in the depths of a forest at dusk, the fresh dew and dwindling camp fire bringing out the wonderful scents of her surroundings.
“Do you usually do things like this?” she asked as Shoto combed the hair from her face and his hands forcing her to reveal her full self. Just like Katsuki, he looked at her like she were a piece of art and he was blessed, and finally he was able to touch her; fingers barely present as they swept over her nipples and nails scraping at her stomach just underneath her belly button.
“We sometimes do this together...but not with an omega. Not anyone else.” Shoto was calm as he spoke, leaning down and stealing a kiss from her lips. He wasn’t like Katsuki; where Katsuki demanded his satisfaction and found it, Shoto sought it out by navigating what she wanted. All she wanted was more - the part of her brain that could function like a normal person was switching off, teetering on sanity and completely succumbing to her baser instincts. Shoto was driving her to full omega mode and she didn’t care. As he pulled away, Ochako chased his lips, only to force her back to the bed - her impending whine echoing around the room like a bratty child. “Not yet, Ochako. Soon.”
“Why? I want you now,” she whined, slumping back into the bed and almost folding her arms as she became cross. Shoto shook his head as Katsuki pushed him out of the way and she understood what he was doing this whole time. Katsuki was naked, kneeling on the bed with the condom on and a smirk on his face. He spread her legs, pushing her thighs up over his own as he positioned his cock at her entrance. Her eyes widened, swallowing as she anticipated the intrusion.
“Put it inside her, I want to see what her face looks like when she’s so full she can’t think straight,” Shoto said, almost smiling as his hands held onto Katsuki’s shoulders. Ochako bit her lip as Katsuki sunk inside without any effort. Ochako gasped, clutching at her sheets, trying to rock into him - only to have him thrust into her twice and leave her completely. Ochako sat up watching as Katsuki shoved Shoto in front of himself her slick still dripping from his cock as he braced Shoto’s hip.
“What? I thought -”
“Nah, you’re gonna sit there, watch and let your heat make you a fucking mess,” Katsuki said, relaxing back as Shoto grasped Katsuki’s cock and tried his best to position himself. Katsuki reached for the emergency heat kit and found the lube - from what Ochako knew, it was for those omegas that had trouble producing enough slick to let their partner in - but now it was used differently. He prepped some in his hand, stroking his cock and soon spread Shoto’s ass to coat his asshole with the lube. With a satisfied grin, Katsuki pushed himself inside.
Ochako’s jaw dropped as Shoto took Katsuki in. His teeth were bared briefly as he sank down and his mouth went slack. On his knees, he pressed down onto Katsuki’s length and began to ride him - up and down, the sound of skin on skin was making another wave of slick gush from Ochako and she pressed her hand in between her legs, almost buckling forward and panting like the bitch she was into the sheets. All the while, the two alphas watched her. They watched as she couldn’t stop playing with herself and fall victim to their exploits of alpha on alpha action.
“Shh,” Shoto hissed, almost swearing as he lowered himself down on Katsuki’s cock again, pressing down on Katsuki’s knot. It wasn’t anywhere near as big as she heard they got, but it was getting ready and the thought of it made Ochako whimper. With her fingers delving inside herself, she curled them to get the edge of her heat off, even if it wasn’t that effective - because if she had to watch this and not touch herself, she’d literally be drooling into her mattress with absolutely no outlet.
Shoto braced his hands on Katsuki’s thighs, his cock bouncing in a tantalising dance that made Ochako finally press her cheek into the mattress, watching from the corner of her eye as the movement of their bodies teased her.
“Do you think she deserves a treat?” Katsuki asked, his hand moving to Shoto’s hips and stilling them so only Shoto’s erect cock sat twitching in her line of sight.
“Yes...please,” Ochako begged, her fingers pressed as deep as they could go inside her entrance. As she looked back at the alphas, Katsuki slapped Shoto’s thigh and ordered him with a quick jut of his hips into Shoto’s backside.
“Yeah, fuck her pretty little mouth,” Katsuki growled, “make her gag on your cock.” Shoto growled as he reached for Ochako, dragging her chin towards him and had her crawling on her knees until he was opening up her jaw to fit his cock inside. There was something about it that made her eyes roll back and everything felt right. The physical contact of an alpha inside her - even if it wasn’t her pussy - she could still have him touching her and it was enough to sedate her.
The truth was, Ochako had no experience with this kind of thing; a fact both of the alphas knew, but she wasn’t entirely sure what made her do what she did. Gripping his hips over Katsuki’s hands, and began to descend her mouth over him in quick succession - and the added pressure allowed Katsuki to fuck up into Shoto. The contact made him sink further into Ochako’s mouth, making tears prickle at the side of her eye with the invasion getting too intense for her untrained mouth and jaw.
Shoto’s hand came up, pressing her head down onto his shaft, the tip touching the back of her throat. She was clawing at Katsuki’s hands, almost bouncing on her haunches to get what she wanted. It was so close to something but not quite there. Why couldn’t she be filled just a little bit when there was a cock waiting for fuck her. Ochako hummed around the length, Shoto’s finger tightening in her hair.
“Katsuki, stop, I’m gonna -” Ochako watched with tears in her eyes as Shoto’s face contorted. Katsuki pushed her chin back and made sure she could no longer have Shoto in her mouth. Katsuki then slammed Shoto down on his lap and gripped the base of Shoto’s cock, just above his inflating knot.
“Can’t even keep it in?” Katsuki said, hand firm around Shoto’s cock as he relaxed, falling back against Katsuki. Ochako’s tongue fell from her lips, watching as the two alphas caressed each other, lips hovering but not meeting yet; she didn’t know she wanted to see such a sight.
“Let’s see how much the omega can take before cumming,” Shoto challenged and Ochako bit her lip, watching as Katsuki’s cock slipped out from Shoto and he swapped over the condom he was wearing for a new one. At the same time, he handed one of to Shoto and the two alpha got ready. They were both breathing hard - harder than they had been moments before.
“Is something wrong?” she asked, her breath shaking, her hand pressed between her thighs, tightening as she smelled how their pheromones changed.
“Your pheromones are...getting a bit intense,” Shoto confessed, not daring to look at her. She was making their eyes do that? Making them look like they could devour her without warning.
“We’ve gotta fuck you fast because you’ll send us into a rut,” Katsuki admitted. Ochako’s eyes flicked between them before she said the thing that her omega begged her to.
“Is that a bad thing?”
The alphas exchanged possessive smiles before their eyes finally landed on her.
“Oh, she wants us to ruin her,” Katsuki beamed.
“I need you. I need you both,” she confessed, as Katsuki laid back against the bed, presenting himself like he were a damn meal. Her mouth was watering regardless.
“C’mon cheeks, get on your knees and fuck me.” Ochako pursed her lips as she crept up and sat on Katsuki’s thighs, her slick already sliding down his legs as she propped herself in place. Katsuki’s hands ran up her waist and once more, grazed at her breasts.
“Can I?” she asked, her hand running up his length, the twitch in her palm made her antsy.
“What does your other alpha want?” Katsuki asked, his hands placed behind his head as he watched her, tilting his head with a confident smirk on his face. Shoto moved behind Ochako, his cock rubbing in between her thighs and getting saturated with her slick. One hand bound in her ass as he said in her ear, almost making her completely submissive.
“I want this ass all to myself,” Shoto said, and after lathering up his shaft, positioned his cock at her ass.
Was this really going to happen?
“Cool her down, half and half. We’ll make her feel good together,” Katsuki told him, and without any delay, from behind Ochako, Shoto’s right hand met her waist and she shivered from the cold. It was everything she needed - her sanity returned with one cold hand - and she knew she needed them.
As Shoto traced fine, cooling lines down her body with his finger tips, making her shiver, she couldn’t help but think of Katsuki too. How they were both so different, but each side of them was something she wanted to enjoy.
“Todoroki,” she hummed.
“Really? Not Shoto? Not gonna give your alpha his name?”
“Alpha,” she purred.
“Shoto,” he corrected again, “You think of me as I stretch you wide.”
“Shoto,” she corrected, and he guided Katsuki’s cock inside Ochako, his hand pressed down on her shoulders and she cried out. Over her, Shoto leaned down, pressing a delicate kiss to her neck and continued to cool her.
“No,” she whined, “I want to feel you. I want what it feels like,” she said, not sure if she was making sense. She didn’t want to be cold - she wanted the heat to bubble up from within and make her the omega that these alphas craved. Shoto kissed her jaw.
“Anything for you, beautiful.”
Ochako laid her hands on Katsuki’s chest, rising up and down as she let her heat finally hold power over her actions. It felt natural to be on top of him, to ride him and feel the press of a knot that was so ready for her. Was she ready for him? Fuck, she wanted him, but was she ready? Fuck! She wanted more - needed more. Suddenly there was something cool running down her backside, and as she glanced over her shoulder, she could see Shoto’s spit running over her ass as he pushed his cock over it, lubricating the tip as he pushed himself inside.
“Ah!” she hissed, nails instinctively clinging to Katsuki’s chest. He hissed too, his head thrown back as Shoto whispered apologies in his ear.
“It’ll get better, I promise,” he said, hands running on the inside of her thigh and collecting slick to add in some much needed aid to her current ache. “Tell me if you need to stop.”
Ochako merely nodded, pushing back against him to see if the pressure would wane and she could get some pleasure from it. Shoto merely stopped her hips, allowing her to get used to the stretch as Katsuki fucked her, without even letting her feel how she was being filled in the untainted hole. Well, until now. “More,” Ochako begged and Shoto finally moved.
And she was in heaven.
Ochako had never been so filled in all her life and it was beyond what she thought was even a possibility.
“Fuck, she smells amazing,” Katsuki groaned as he and Shoto were seamlessly fucking her in rhythm - one in, one out, replacing each other with whoever was furthest in and all she wanted to do was cry. All because she felt like she couldn’t breathe - her life was stolen from her as she tried to buck and feel at what her body needed, but all it was calling was a string of swears that all just signalled her mounting pleasure.
“Do you think she’ll work for her knots?” Shoto whispered, nipping under her jaw as she whimpered and clawed at Katsuki’s chest.
“Yes,” Ochako confirmed, “but I think two big alphas should be able to satisfy their omega. And so far, I’m not satisfied,” she challenged and glanced over her shoulder to see the sceptical look her two alphas shared. But one challenge to an alpha close to their omega induced rut, and they were both set off. Katsuki’s hands were digging in hard to Ochako’s waist as Shoto’s clamped down on her hips, fucking her without remorse, not even savouring her cries of passion as she came, over and over again as her heat made her succumb to the pleasure she had been craving.
“Always knew there was something about you I liked the most,” Katsuki hummed, driving himself up and his knot almost catching to make her throat close in anticipation.
“What’s that?” Ochako whimpered, unable to contain her voice.
“Your bite,” Shoto finished, driving home hard enough to have his knot snaring at her ass. Ochako’s nails scratched down Katsuki’s chest. Her slick was running down her legs, seeping from her core every time Katsuki thrust into her. Shoto’s hands ran over her thighs, gathering the wetness and spreading it over her ass as he filled her.
“It’ll hurt at first, but I promise it’ll be easier,” he warned her suddenly, and Ochako moaned, arching back as much as she could to feel the press of his body as he was preparing her further.
“Just fuck her, half and half,” Katsuki scowled, fucking up into her with a speed that she could feel his knot trying to edge its way inside her. Ochako had to admit, she was trying to bear down onto it as it teased her. Ochako wanted to lean down, to kiss Katsuki and make him shut up and please her and return her sanity that she felt he had stolen. Instead, she was yanked back up with two hands around her neck, Shoto’s thumbs running down either side of her spine as he held her.
“Ah!” Ochako cried, Shoto’s hands gripping around her throat a little tighter as she tried to keep herself upright without choking. To stop her from falling down but allowing the pressure to remain, Katsuki rose, letting her chest rest delicately against his.
“We got you, just ride us like a good lil omega bitch,” Katsuki purred, nipping at her neck as he thrust up into her aching cunt. It was being thoroughly abused, her body aching with pleasure and being stretched beyond what she’d ever experienced before.
“Right there,” she sighed as she felt the stretch from her ass. Ochako reached behind her as she braced for the fit that was coming her way.
“C’mon half and half, show her what you have,” Katsuki urged him. It only took a few more thrusts to have Shoto’s knot lodged in place - in a place a knot was never supposed to be - but it was firmly pressed inside her and she didn’t dare to pull away. Ochako struggled to breathe, Katsuki rearing up, kissing her senseless - proving to her that she could breathe again, but she was lightheaded for it all. And Ochako was seeing white when Katsuki’s knot thrust up into her in pleasurable pain.
The two alphas could not move, giving her faint thrusts as they chased their high that was mounting within them, and it would only come when -
Ochako gasped as Katsuki’s fingers found her clit, teasing and playing with it so vigorously that she felt herself shaking in his lap. All she wanted to do was dash away, far too overstimulated to have him racing to her release. Shoto’s hand loosened over her throat to wrap around her torso and keep her as still as possible as Katsuki rubbed at her clit.
“Wait, wait! Oh gods, wait!” she stuttered, not quite sure what she was saying. Katsuki continued to play with her clit, watching as she struggled to breathe and control herself.
“Make her cum, Katsuki,” Shoto said, urging her forward as he leaned down onto them both and snared his hand around Katsuki’s neck, craning him up to kiss him aggressively. The sight along with Katsuki’s fingers rubbing against her, Ochako was gone, cumming hard on Katsuki’s cock as she felt both their bodies tense and released their own pent up passion.
Once Ochako had completely come down from her high, she panted against Katsuki’s chest, holding herself to him as the ache of what her body had gone through was streaming back to her mind. Shoto nudged her to the side, sliding her as delicately as he could to have her laying on her side - sandwiched between her two alphas. She hissed in pain, and instantly, both alphas pampered her with kisses, hands running over her body as though she were a wounded beast. Katsuki’s quirk activated, the slow rumblings of his power running over her skin as he dulled the ache of her exhausted muscles, and Shoto’s cooling hand pressed in between their bodies to soothe the ache from his knot.
And so there she was, lying between two men that were firmly lodged in place and completely spent. Not many omegas could say their first time was a threesome with two alphas that adored her.
Ochako stirred, trying to angle herself better in the bed when both alphas gripped her hard.
“Where are you goin?” Katsuki snarled, nipping just under her jaw before his eyes reached hers.
“I was getting more comfortable,” she offered as Shoto kissed her shoulder.
“Leave her alone Katsuki. Just because you know nothing about comfort doesn’t mean she’s comfortable.”
“So I’m guessing you guys do this often?” Ochako asked.
“You really think I could fit inside his asshole with a bit of lube and a single thrust if we didn’t?” Katsuki countered.
“I’m just asking!” she replied with a giggle.
“Glad we added her into the mix,” Shoto said, humming as he pressed his forehead against the back of her neck.
“Isn’t it rare for alphas to be with each other?” Ochako asked, her curiosity getting the better of her.
“Yeah, but we aren’t together. Just fuck him when the tension gets too intense,” Katsuki grumbled.
“So...you want an omega to make it more fun?” she said, chewing on her lip. The two alphas rose slightly to catch each other’s gaze and share a nod between them.
“If you fucking think,” Katsuki started, just as Shoto reached around, touching underneath her chin and tipping it so she’d face him over her shoulder.
“If you think this was only happening once, you were mistaken.”
Oh gods...Ochako was gonna get fucked to death at this rate.
And she found that she didn’t mind.
