This is another fic I have been thinking about, haha I've been on a roll lately. Been wanting to write a Bakugou omega fic, so I thought why not. Everything is laid out pretty clearly in the first chapter, just about how omegas are treated etc in this verse. I really hope you enjoy it because I was very excited to write it.

I haven't decided on a pairing yet so if there is someone you would like to see Bakugou with, let me know! It might help me decide It will be slash though.

Also warning for a vague mention of past childhood abuse, just so people are aware incase that is a trigger for you.

I do not own My Hero Academia.

Chapter One

Bakugou took a deep breath as he walked out of the school counsellor's office. He had been seeing the counsellor twice a week for nearly a year now. Mandated by his teachers after all the incidences in first year. He had been adamantly against it at first, but it was either this or leave and he knew he needed to go to school here to become the world's number #1 hero.

Surprisingly, after he had stopped fighting them so much the sessions had grown on him. It gave him a safe space to feel vulnerable and voice his fears without fear of judgement. And since Bakugou never let himself show vulnerability in front of people it had been something of a godsend.

The sessions had helped him work through his deep seeded insecurities and self-loathing, stemming from his shitty parents and the fact that he had presented as an omega.

That's right Bakugou Katsuki, was an omega. His parents were both alphas and had been, let's say, hard on him his whole life. When he had presented as an omega, they made it very clear just how disappointed they were, he still had the marks to prove it. They'd put him onto suppressants and brought him a scent blocker before pretty much wiping their hands of him. It didn't matter what he did, how hard he worked, it was never good enough for them.

To say that this had had a detrimental effect on him would be an understatement, but thanks to his counselling sessions and living in the dorms, away from his parents for the first time, he was finally ready to have a try at just being himself.

He was fucking scared.

But what finally made him decide it was the right thing to do was the thought of all those other omegas out there who were told that they couldn't do something because of their sub gender. That they couldn't be a hero. Bakugou was going to show everyone that omegas were just as fierce as any other.

In general omegas were treated equally to the other genders but there was still a lot of people who viewed them as the softer, weaker gender. They may be right, to an extent about the softer part, but they were definitely wrong about the weaker part. Omegas could kick ass as well as anyone, just because they liked cuddling and soft things didn't detract from that.

Bakugou had kept this side of himself hidden behind harsh words and harsh actions since he presented. Determined to come across as a strong, fierce alpha so that no one ever found out he was an omega, so that no one ever had reason to question his worth.

He now realised that his worth had nothing to do with his sub gender but everything with how he viewed himself. Accepting himself was another challenge but Bakugou would never back down and admit defeat. He now realised just how miserable he had been and refused to live the rest of his life that way. That was letting his shitty parents win.

His counsellor, Aina, had arranged for him to stay in the dorms during breaks and once he finished school, he would get his own home. He would never be returning to that place again. There was even scholarships set up to assist students like him financially, he was moving forward and wasn't going to waste his time looking back.

So that's how he found himself where he is now, on his way to Recovery Girl for a checkup before coming off his suppressants for the first time since presenting.

He took a deep breath, calming his nerves before pushing open the door and walking in. Recovery girl was waiting for him, obviously already filled in on what was happening.

"Bakugou" she greeted.

Bakugou just nodded his head.

"Come take a seat and we'll get started."

The next hour was probably the most embarrassing of Bakugou's life to date.

He was stripped down, poked and prodded, questioned explicitly about his bodily functions and sex life. He'd blushed so red that he wasn't sure his face would ever return to normal.

"Yes, I produce slick when aroused" he'd mumbled hotly, eyes looking everywhere but at the person in front of him.

Recovery girl had nodded, making a note on her clip board.

"Expect that to increase exponentially once the suppressants wear off. There are liners you can wear inside your underwear if you're concerned."

Bakugou had just gaped at her, what was he supposed to say to that.

"It may take a little while for your heats to regulate once the suppressants wear off, once they do return to normal, they will come every three months" Recovery girl continued, seemingly unaware of Bakugou's turmoil.

"You can spend your heats in your dorm room, they are designed to block all scents from leaving the room, you would already know they have state of the art locks. Though, if you choose to, you can spend your heats here. It will be up to you. Either way you have to let your teachers know when a heat hits you."

Bakugou just nodded, he already knew all that.

"If you decide to have sex or mate during a heat, I suggest you use contraceptives to avoid pregnancy."

Bakugou's eyes bulged out of his head at that, but still, he didn't say anything.

"I will give you a few pamphlets and samples. Your best bet will be condoms though, as they are the most effective."

As Recovery Girl thrust information pamphlets and a box of condoms into Bakugou's lax hands, he managed to pull himself together.

"I - I won't be needing any f fucking condoms!" he growled.

"Better to have them and not need them, then need them and not have them" she said matter of factly and Bakugou was wise enough to see the sense in that even if he thought the whole thing was ludicrous.

"There are all sorts of toys you can buy to help you through your heat, there are brochures in there" she said pointing at the pile clutched in Bakugou's sweaty grip. "I would strongly suggest purchasing a few."

"Your omega instincts will start to get stronger as the suppressants fade, I know it may be difficult for you, but it is best to just embrace them."

Bakugou swallowed thickly, "Aina will be available for me to talk to, if- if I'm struggling."

"Good, I'm here for you as well, if you need anything at all."

Part of Bakugou wanted to lash out, he didn't need anyone's help! Didn't need anyone to look down on him! He did the breathing technique that Aina had taught him, calming himself before speaking rashly. He knew Recovery Girl was nothing but sincere in her offer.

"Thank you."

Recovery Girl smiled brightly at that.

"There are also a few brochures in there for nesting materials and the like."

Bakugou looked down at the pile in his hands. Nesting was one of the things he was looking forward to most. Even though he had been on suppressants they had never quite squashed the longing for a nest, for soft comfortable things. He had never allowed himself to give in to his urges, seeing it as a sign of weakness but now he was very much looking forward to scratching that particular itch.

"I think that's enough to be going on with. I'm sure I've overloaded you enough for one day" Recovery Girl joked. "If you have any other questions, come back and see me anytime."

Bakugou's head buzzed with information as he made his way back to his room. He walked in a daze, pamphlets, brochures and condoms in his arms. His mind was swimming.

He was so caught up in his own thoughts that when he rounded the corner to the hallway to his room, he ran smack bang into a firm chest. It was a testament to how distracted he was that he managed to be knocked flat on his ass. Bakugou blinked up dazedly.

"Oh sorry, Bakubro! I didn't see you there" Kirishima said with a grin.

"You alright?" Denki asked peering down at Bakugou from beside Kirishima.

"Course I'm fucking alright, dunce face" Bakugou grumbled pulling himself to his feet.

Kirishima grinned, "here, let me grab these for you" he said, reaching down for the things Bakugou had dropped, Denki leaning over to help, when everything seemed to freeze.

Bakugou glance down to see the box of condoms sitting on top of the pile of papers that were spread all over the floor.

"Ah, bro?" Kirishima asked a soft blush gracing his cheeks.

Denki just looked shocked at having caught Bakugou carrying around a box of condoms, not even noticing the pile of pamphlets and brochures. His eyes wide and mouth hanging open.

Bakugou felt his whole face heating up again, "don't fucking touch my stuff, shitty hair!" the blonde screamed, embarrassment making him lash out.

He quickly leant over, scooping everything up before barging through the pair and off to his room.

Kirishima and Denki were so surprised that Bakugou's door was already slamming before they could even think of some kind of response.

"What was that?" Kirishima asked confused.

"Well, I'd say it looks like our blasty boy is looking to get lucky" Denki said with a leer, a slight blush dusting his cheeks.

Kirishima just rolled his eyes, surprised and maybe a little hurt that his best friend hadn't confided in him. "Let's go get something to eat" the red head said instead, deciding the best course of action was to change the subject.

"Yeh!" Denki cheered and the pair headed for the lift.

Bakugou breathed a sigh of relief when he heard the lift doors close, he had been worried that the pair may come knocking, asking a bunch of stupid questions. He hoped they hadn't paid attention to anything other then the condoms. He wasn't quite ready to tell people that he was an omega just yet and if he was that wasn't the way he wanted to do it. He was thinking of just letting his natural scent become apparent as the suppressors wore off over the next few weeks and let people figure things out for themselves. That would probably be the easiest way to do it.

He would be the only omega in class 2A, but he didn't think his class would mind that much. He knew there was an omega in class 2B and there was some in the general studies students, so it wasn't unusual to see omegas around, though they were the rarest of the sub genders. His class consisted of mostly alphas and a few betas, it wasn't a surprise though, hero work tended to appeal to alphas the most.

He started getting ready for bed. It was still pretty early, and he hadn't eaten dinner yet, but it had been a long day and he needed some time to himself. Some time to sort out his thoughts and read the info he'd been given that day. He chucked the box of condoms into his top bedside drawer but before he could close it again, he pulled out the bottle of suppressants. He stared at the plain white bottle for a moment before chucking the whole thing in the bin. He had made his decision, now it was time to start living his life.
