Work Text:
Midoriya felt the air rush out of him as he hit the ground yet again. He took a moment to just sit there, regaining his breath and trying to ignore the biting pain in his ribs. A pink hand popped into his vision and he grinned as he grabbed Mina’s hand, pulling him up.
“Wow, Mina! You’re getting a lot better at controlling your acid, that was the toughest spar we’ve had today!” Mina grinned, her black and yellow eyes twinkling.
“Yeah, well I have the best tutors!”
“Oh yeah, your boyfriends are Sero and Kami right?” That got a bright blush out of the alien, who retreated to her workout bag. Midoriya’s smile faltered a bit when he realized that his breathing hadn’t evened out yet. That wasn’t good. He grabbed his water and took a deep drink, trying to calm his breathing down. Mina looked mildly concerned, then it felt like a vice was gripping his chest and he curled into a ball on reflex, trying to rip the iron grasp off, trying to suck air into his chest.
Aizawa was watching the happenings of the chat in boredom. The most exciting thing was the grape child going through Midoriya’s room, and that was done with. Then notifications for the chat started rolling in, so he finally started paying attention again. Reading through it, he furrowed his eyebrows at Mina’s declaration that Mido looked like he couldn’t breath. Shooting a quick text out, he looked up in the chat.
Midoriya is at the training fields.
Not even worrying about his phone, he flung the door open and started power-walking to the training field, ignoring anyone who got in his way. His capture weapon was draped around his neck, ready to be used to get anyone out of his way. Then he finally caught a glimpse of the field, and saw a curled up, shaking ball of green while Mina was panicking across the field.
His capture weapon lashed out, gently grabbing Midoriya around the forearms and pulling him out of his little ball. Aizawa’s hands went to Midoriya’s shoulders, to ground the boy, when he felt straps under his palms. He furrowed his eyebrows. Midoriya wouldn’t need to wear a sports bra to practice, so what was he wearing? It was too tight for a tank top. He felt Midoriya still, obviously giving his teacher an opening. His back was to Mina, so she couldn’t see what was going on. He hesitantly reached down Midoriya’s collar, feeling a tight stretch of fabric spanning his chest. A strip of velcro was in the middle, holding it together. Aizawa’s eyes widened despite himself. He knew exactly what this was, one of his classmates had been transgender. He also knew that exercising in a binder was dangerously unsafe, and that Midoriya would know that.
So why….
Ignoring the scolding for now, he ripped the velcro apart and Midoriya’s breathing instantly calmed down. On instinct, a loose end of his capture device wound itself gently around Midoriya’s torso, giving him a semblance of a flat chest while not being as tight as a binder. A good middle ground.
“Problem child, you know not to exercise with a binder on, don’t you?” Midoriya flinched at the sudden question, before stuttering a response.
“U-uh, yeah I do, it was just…… dysphoria was really strong and I didn’t want to take it off because-” His rambling was interrupted by Aizawa raising an eyebrow.
“Do you have a compression shirt?” Midoriya nodded.
“Okay. Mina? Can you ask either Bakugou or Todoroki to come and help him out, and to bring a compression shirt?” The girl shouted an affirmation before typing on her phone. Aizawa turned back to Midoriya.
“Okay, when I tell you to, start coughing.” The confused look he got was so purely Midoriya that he rolled his eyes.
“Just do it, problem child.” Midoriya started to cough, and almost instantly fluids came out of his mouth. When the coughing fit ended, Aizawa held back a smirk at the bewildered look on Midoriya’s face.
“That’s what happens if you wear your binder for too long. Don’t do it again.”
