Midoriya was in literal hell. He sat on Katsuki's couch bundled in soft blankets, irritated that he found comfort in the foreign material. He was an omega. A fact that, to this day, had never bothered him before. He had his yearly heats that were a pain but he had an excellent handle on them so they were whatever. He had always been less affected by alpha pheromones and alpha commands rarely even rattled him but now… he sat on a strangers couch with his traitorous fingers clutched to a blanket covered in alpha pheromones. Katsuki’s pheromones. His new alpha hero partner.
Midoriya hated it. This feeling of loss of control. He relished in control. Every action he made, every pattern he had, he controlled it. Even his heats he regulated like he was born to do it. He could run with the big dogs because he had never acted like an omega before.
But low and behold. Apparently his omega decided that this alpha could control him. Apparently his omega was submitting to him and he loathed it.
It had been just like any other day. He got up, did his morning routine, went to work, met in the conference room for the morning meeting before heading out for patrol. And it was in this meeting that he had met said fucking alpha.
Bakugou Katsuki was a transfer from the next city over and would be a new permanent hero at their agency. Midoriya didn't mind. He liked making new friends. He wasn't a social butterfly but he was good in small groups. However when the alpha had walked into the room, tall, broad and gorgeous he was intrigued but otherwise thought nothing of it. But when he spoke to introduce himself it sent a shiver down his spine. Another hero, Kaminari, was a notorious idiot and provoked him. Katsuki had snarled at him, a classic alpha sound that in a room full of alphas and betas and usually himself, wouldn't have made a big splash. However the naturally aggressive sound triggered something deep in him and he collapsed to the ground immediately. Just full dead weight, bam! On the ground. How humiliating.
Of course it garnered attention and several of his coworkers who know him well enough to know this was highly unusual went to his aid. Mina, a beta friend of his, looked at him strangely as she helped him up.
“What was that?” she asked and Midoriya couldn't say himself.
“I have no idea.” he answered, puzzled.
“You have an omega in your team?” he heard Katsuki ask and his immediate response was to growl and defend himself as he had hundreds of times before. The alpha obviously wasn't used to unsubmissive omegas and growled in response. Again his treacherous body went limp.
“I think you finally met your match, Midoriya.” she giggled and he grumbled angrily, rising back up on shaky arms.
“Are you fucking kidding me?” he scoffed and the team lead insisted that until “Midoriya can comfortably work alongside Bakugou, they will cohabitate.” How fucking cliche.
Midoriya had never despised his boss like he did at that moment. Katsuki was also caught off guard by the demand and argued with him for a good five minutes before demanding that Midoriya stay at his apartment instead of going to the omega’s.
So now here he sat on a stranger's couch completely offended by his own body’s reaction.
He knew that this was not something either of them were comfortable with but Midoriya strongly believes it's a hundred times worse for him. Did the blonde not think about the fact that bringing an unmated omega, clearly weak to him, into his den might be a bad idea? He growled under his breath and laid down, flinging the blanket all the way over his head. He squeezed his eyes shut willing himself to relax enough to sleep and an annoying ‘ping!’ interrupted his focus.
He gripped his phone and huffed pulling the screen up just in time for the blanket to be ripped off of him.
“Hey!” He stood up, reaching for it and Katsuki growled lowly. Midoriya’s hold on his phone relaxed and just like at the meeting his body lost all strength and he fell limp to the ground or he would have if Katsuki’s arm didn't wrap around his back and catch him. Midoriya pouted and waited a few seconds to regain function.
“You're enjoying this, aren't you.” he grumbled and a deep chuckle rose in the alpha’s chest.
“I admit it's fun but if we don't test it then you'll never get better.” he reasoned, Midoriya's pout strengthened and he trembled to raise his head enough to aim his pout at the smirking blonde. They maintained eye contact for a few seconds before Midoriya gave up with a heavy sigh.
“Just put me on the couch, will you? Feeling isn't coming back fast enough.'' Katsuki hummed and turned, sitting down on the couch and maneuvering the omega to straddle his hips, leaning his weight against his chest, his head falling to his shoulder. Katsuki had made him quite comfortable but like hell he would admit that.
“This is not what I meant.” he huffed.
“I know but this is better. Your omega is not the only one acting up.” Midoriya could hear the grimace and he felt a bit better. “I don't know how long this might last. Not sure what happens to you but I know my alpha is constantly rattling its cage trying to get to you. I only put us like this to shut him up.” he hooked his chin on his shoulder and sighed. Midoriya had most of his strength back by now and gave in. He wrapped his arms around his neck and felt the blonde’s arms wrap tight around his waist.
“We’re fucked, aren't we?” he whined and Katsuki chuckled.
“Seems like it.”
