    Summary

    secondary genders don’t usually pose as a problem for most people. they are instincts, urges within them that they could easily suppress. though, a small few are different. their secondary overpowers their primary, forcing them to act on their primitive instincts with little to no control.

    as it turns out, katsuki just so happened to be doomed with this lack of control.

    or,

    after a crude physical exam, katsuki bakugou is diagnosed as pure-dominant omega. his omegan instincts are strong and uncontrollable, often overbearing. all his life, he was unable to mate with or merely smell the pheromones of an alpha without being sent into a whole world of pain. his omega craves something else.

    that something just so happens to be izuku midoriya, a prime enigma with cock so long and a knot so huge, even other dominant-omegas couldn’t take him or his aggression.

    but katsuki is different.

    at age eighteen, the pure-dominant omega is paired with the hulking, animalistic enigma who just so happens to be twelve years older than him.

    Summary

    I did a connected series of prompts for #nastydkbkweek! I cover a couple of kinks, and you can take them as stand alone stories or not. Kinks covered in each chapter will be specified in the beginning notes, but all the biggest kinks are in the tags. The whole fic is from Katsuki’s POV, so check out the songs in chapters 5 and 7 for more of a vibe on how he’s feelinggg.

    Summary: Katsuki has always run the show with his partners and kept things casual, to blow off steam and let loose before he has to be a hero for the next week, and the one after that. But the one person who he ever thought about topping him was Deku.

    Or: when Katsuki drunkenly tells Izuku he's into him, Izuku is interested, and they get closer as Katsuki explores being obedient for once.

    Summary

    Izuku's stomach turned over. He had told himself a thousand times that this was it. That the next time Kacchan started nesting, he'd shoot his shot. They were third years, and Kacchan was easily his best friend. He was also the love of his life. Every time Kacchan hit pre-heat, courting gifts would flood the dorms and Izuku would watch in terror as Kacchan inspected each one and then crumple in relief when he turned them down.

    He couldn't wait on the sidelines anymore and wonder if Kacchan would accept him. He had to try, or else he'd miss his chance and regret it for the rest of his life.

    -or-

    Izuku has been planning to court Katsuki for ages. He has the perfect courting gift. He has his approach planned. And he *thinks* he has a chance.
