Mother Hen
Bakugou Katsuki is far from being the ideal omega.
He’s brash, competitive, hot-headed, foul-mouthed, loud and unmannered. He wouldn’t submit to an alpha and would bare his teeth at anyone who tries to dominate him just because of his designation. But, if there is something that gives out that he’s an omega, other than his scent, is that he’s a total mother hen.
It only happens for a few days before and after his heats, though. And the first time it happened, class 1-A almost lost their shits, Izuku was the only one that didn’t seem fazed by Katsuki’s odd behavior.
“Midoriya, what’s going on with Bakugou?” Momo asked during their lunch break. Katsuki was sitting with his friends, far from them, his usual everlasting frown had disappeared, leaving behind a soft and young-looking face.
“Huh? What do you mean?” Izuku tilts his head, putting his chopsticks down on the bowl. Momo could say he was genuinely confused by her question.
“It’s like he suddenly changed his personality.”
Izuku took out his phone and search through it before answering Momo. “Oh! He’s near his heat,” he says as if it makes all the sense of the world. For Izuku, it does explain everything, but Momo just stares at him, even more confused. “After and before his heats he turns like this, something about hormones and nesting,” he elaborated his answer. Everyone around him listening. “Just let him mother you, it’s the best.”
Now they were in their third year, and it has become the norm that, every two months, before and after Katsuki’s heat, he would turn into the group’s mom.
Katsuki was always the first to go to sleep and the first to wake up. He would cook breakfast for everyone and make sure everyone eats their portion, especially Aoyama who has a problem with eating that Katsuki attributes it to his quirk, and Momo, who needs to eat a lot due to her quirk’s nature.
After that, he would clean everything (he also turns into a clean freak, due to omegas nesting tendencies during their heats) and take a bath the last. Sometimes Eijiro and Momo would help and he would finish quickly and take a bath with the others.
In class, Katsuki would keep a close eye on everyone’s scent. Omegas have the most sensitive smell sense of all the secondary genders, so for Katsuki is easy to detect even the smallest shift in any of his classmates’ scent. He would always try to help them calm down whenever he smells they’re stressed, nervous or tired. Everyone know that they can also come to him if the want him to scent them, Katsuki would happily oblige.
Denki loves to be scented by Katsuki, maybe because he’s also an omega and omegas tend to search comfort in their fellows. Shouto also likes it, though it’s hard for him to admit it. But Mama Katsuki knows better, and he would always make a little spare time to scent him thoroughly, until Shouto is smelling of burnt sugar for hours.
Katsuki hates training during these times, mostly because he’s afraid of his – his friends – getting hurt during it. It was almost painful, and he always has to be calmed down during it. It’s the only time where Katsuki needs them more than they need him.
Once, Ochako got hurt during a friendly match and Katsuki didn’t want to let go of the beta for the rest of the training.
Lunch was the calmest time of the day. Katsuki would sit with his usual group, leaning close to one of the alphas (usually Mina, he just loves how Mina smells, sweet and acidic) and keep track of what and how much they were eating. They usually make sure to eat enough to satisfy Katsuki’s mother hen tendencies, mostly because they wouldn’t like the earful Katsuki would give them if they don’t.
It happened once, Tokoyami barely touched his portion and Katsuki gave the alpha a half hour lecture about eating properly. Since then, everyone makes sure to eat their portion.
After class, they would be mostly free from Katsuki, which would be a relieve but they always missed the blonde fretting over them, it was cute in the weirdest ways.
During this time, some of them would hunt Katsuki down for a relaxing session of scenting, basking in Katsuki’s caramel scent.
Puppy piles and sleepovers were the best part of Katsuki’s overprotectiveness. They were rare, but sometimes, right after his heat, Katsuki’s overprotectiveness would kick in way too hard and he would ask – demand – the others to sleep in the common room with him so he’s sure everyone was safe and sane.
But after a few days, Katsuki would return to his normal self and nobody would mention the past two weeks. It never happened.
But it doesn’t matter, everyone was happy to pretend as long as they could have Mama Katsuki again in a two-month time.
