“Control it.” Bakugou hissed.
“I can't help it, asshole. This building's full of alphas!"
The scent that had been pooling off of Y/N had been coming in buckets for the last twenty minutes. It seemed as if the moment they crawled into the hideout, he’d gone into preheat.
“You’re gonna get us caught.”
Y/N growled at him but didn’t bite back. He nudged Bakugou gently to guide him to cover behind a pile of stacked boxes.
The hall they were headed into had, from what they could see, around 5 goons in it. Low level, young, bright eyed. They could take them down easily, but not without the deafening noise of Bakugou’s explosion, and that would defeat the point of sneaking in the first place.
Bakugou watched them carefully, eyes squinted. All of them had a slight frown on their face, and the longer they scoped out, the deeper they became. He sat back on his heels and looked to Y/N.
“Y/N.”
“I can’t control it!” He growled, pressing hands over each side of his neck, “Is it bad?”
One of the goons finally looked directly where they were hiding, scratching the back of her neck, “Hey, can you guys smell that?”
She took another few steps forward, looking behind her to try and catch the attention of her colleagues. Y/N’s breath hitched, his panic making the smell spike.
Bakugou’s eyes blew wide as she continued forward slowly. He didn’t particularly think too hard about it. He needed to cover Y/N’s scent now, or they would blow the mission for each other, and the other heroes in the building. He was not about to be the reason that other people got hurt. He looked at Y/N’s flushed face for a moment before grabbing him by the collar of his suit.
He yanked Y/N forward to flush them chest to chest, and, before his partner could pull away, buried his face in the crook of his neck. He bit down. Hard.
Y/N slammed a hand over his mouth to muffle a yelp, squeezing his eyes shut. Almost immediately, Y/N’s scent was dimmed by the dull, lifeless smell of an Alpha.
Bakugou didn’t pull away right away. He kept his teeth sunken into the skin until the second goon finally came to the first.
He sniffed, then frowned, “Can’t smell anything.”
“Really?”
“Bosses wife’s upstairs, you’re probably smelling her.”
She nodded gently and sighed, “Yeah, probably, sorry. ‘M on edge.”
As they both moved away down the hall, Bakugou finally let go, wiping his mouth with the back of his hand. He let go of Y/N’s collar to peer over the boxes, sighing quietly.
“Ow, Dynamite.” Y/N hissed.
“Shut up. C’mon, let’s go…”
An hour after the hideout was secured, they were both in the infirmary at UA. To Aizawa’s surprise, neither of them had gotten hurt more than a few scratches and bruises.
Bakugou was refusing Recovery Girl’s help other than to bandage his hand that was bleeding at the knuckles. His head was fine, it would heal on its own, he’d said.
Y/N was less pushy, letting her do with him as she wanted. She was currently having to cut the collar of his suit down so she could check the burn on his chest he’d received when he’d gotten in Bakugou’s way.
Aizawa was standing in the corner of the room, tapping quietly on his phone. Even more surprising, these were the only two students that had gotten hurt. Midoriya had made it out without breaking anything important, and Momo had come out with nothing but bruises.
Recovery Girl sighed when she finally got the collar down. “Oh.”
“Oh?” Y/N murmured, “What is it?”
“Um, Aizawa?”
Aizawa finally lifted his head so he could look past her. He blinked and took a few steps forward, putting a hand under Y/N’s chin to see his neck better.
“What?” Y/N repeated, frowning slightly.
“Did you get caught at some point?” Aizawa murmured.
“No, why?”
Aizawa turned to Bakugou, stepping back so he could see. He let go of his chin so he could gesture a hand towards his neck. Bakugou shrugged.
“What?”
“He has a bite?”
Bakugou shrugged again, frowning, “It’s fine, I did that.”
“No,” Aizawa sighed, looking back to Y/N, “No, it’s not fine.”
Recovery Girl winced and looked over her spectacles at the bruised puncture mark, a hand rubbing her chin. Aizawa groaned and buried his face entirely into his scarf.
Recovery Girl looked at Bakugou with a mix of pity and exasperation, “You bit a little too high, Bakugou. You claimed him.”
Silence dropped over the infirmary. It stretched for five seconds then for ten.
Y/N sat up straighter, eyes locking onto Bakugou, whose hand was clamping and unclamping in his lap.
“You fucking asshole.”
"The fuck did you just call me?!" Bakugou snapped, his ears flushing red.
He bolted upright from his cot. "I didn't claim him! I bit him to shut his goddamn scent up! It was a tactical decoy!"
"A tactical decoy that you sunk deep into his scent gland, Bakugou," Aizawa said, his voice muffled by his scarf. "Do they not teach basic anatomy in Aldera?"
"I know where the fucking gland is!" Bakugou snapped, though his eyes darted frantically between Aizawa, Recovery Girl, and finally, Y/N.
Y/N hadn't moved. He was still sitting on the edge of the examination table, the shredded collar of his hero suit hanging off his shoulder. His knuckles were white where he was gripping the edge of the mattress.
"You’re a fucking asshole," Y/N hissed, his voice dangerously low. "You’re a brainless, fucking asshole."
"Don't talk to me like that!" Bakugou barked, though the usual venom in his voice wavered. “It was an accident.”
Y/N didn’t answer that. He jumped down from the cot, thanked Recovery Girl under his breath and started to walk out. Not without throwing a middle finger over his shoulder and muttering curses under his breath, anxious and angry.
Aizawa watched him go then focused on Bakugou again.
“You can undo that?”
Aizawa shook his head, “No. No one can undo that.”
