I am the Angst Queen (self-proclaimed of course).
Bakugou x Midoriya is my NOTP, so, fear not, this is a Kiribaku fic, or, more correctly, a Bakushima fic. I hope you enjoy it!
Bakugou was an alpha. And like the alpha he was, he had to show he was superior. Especially to little omegas, just like shitty Deku. The small fucker had annoyed him since before they'd known their secondary genders and had followed him around. Katsuki was an alpha, of course. Like he'd ever be anything else, given his amazing quirk and how good he was at everything. And Izuku, the little shit, he was useless and weak, of course he'd been born to be an omega.
A useless, slutty omega that would just beg for him and other alphas to take him.
The blond boy let out a pleased snarl as he thought about the idea of Deku whimpering, hoping to be full of alpha cock. Bakugou's alpha cock.
But Midoriya being an omega wasn't the only reason Katsuki had to bully him. He had to show him how weak he was, how defenceless, and how stupid. The little shit wanted to apply to UA when he was quirkless and an omega. He was just asking to be bullied.
It wasn't until much later, when the blond overheard something that unsettled him deeply, that things changed. Deku had been hospitalized due to complications related to his secondary gender. Apparently some sort of stress had caused his heat to come early, before his body was prepared for it and had ended up damaging him both psychologically and physically. And strangely enough, Bakugou had felt responsible for it. He knew why the little fucker was stressed and why his heat had come early. He didn't want to admit it but he knew it had been him.
And it only got worse when Izuku was finally released from hospital. His once a month heats were extremely violent and no amount of medicine could help him.
Luckily – or not – Katuski was smart and had read about it somewhere. The way to help Deku out.
He knew that if they paired, the heats would be less violent, so, as the alpha he was, he took the alpha way out.
He cornered Midoriya after class and barked at him to sit and listen to him. Scared, Izuku did as he was told, not looking him in the eye as he did.
"I'm going to bite you." Bakugou stated. Of course the green haired boy was confused and didn't understand what he was saying. He thought this was some new way the blond had to bully him and trembled in his seat.
"I mean I'm going to pair with you, you stupid omega." Katsuki snarled, exasperated. "That way your heats will be better."
"But… but why?" Deku whispered, still not having the courage to look at the other.
Bakugou was never going to admit that he felt responsible, that he felt it was his fault that this had happened to Izuku.
"Do you want to get better or not?" He growled, leaning forward.
Midoriya nodded his head, his locks of green hair bobbing up and down as he did so.
"Yes, I want the pain to stop."
"If I bite you, it will make it stop, in it's majority. You will still have to take the suppressants."
"I know, the doctor told me." The smaller boy whispered. "but yeah, what you're saying is true. There's a big chance being pared will make my heats tolerable, even if my mate doesn't mate with me during them."
"Just so we're clear, I am never having sex with you." Bakugou's red eyes were on the omega, his face distorted in hatred and disgust.
"I don't want that either." Midoriya gasped, still frightened.
"Good. Now…." Katsuki leaned down as Deku showed him his neck. He loosened his collar to give him ample room and the blond licked his lips in anticipation. For once in his life the boy underneath him actually arouse desire from within him. "This shit's forever, you're completely sure you want this, right?"
Izuku was silent for longer than he wished to be, but he eventually nodded and just said: "Go for it."
And Bakugou sunk his teeth in, his fingers curling at the delicious sound of the boy gasping in pain under him.
