Chapter Text
Katsuki had been having a decent day. He’d kicked some villain ass, gotten some praise, and he’d even kept the damage to a minimum. He was almost proud of himself.
However, he was glad to finally be able to head home. He and Deku shared an apartment. Their rivalry had gotten them on better terms, and now he’d call the nerd his closest ally (or friend if you wanted to be technical). They’d moved in together after UA to share the expenses, and had just kinda stuck with one another ever since. It’d been three years now, and their living arrangements weren’t the worst, so he considered it a win. If you’d told middle-school Bakugou he’d be living with Deku after he graduated high school, he would have said you were insane (probably blowing up a few things for good measure). But now, he practically couldn’t imagine not living with the nerd. Katsuki pretty much knew everything about him at this point.
Which is why, when he opened the door and saw Deku standing silently in the middle of the living room, facing away from him, he immediately knew something was wrong.
He quietly entered, setting his things down on the kitchen counter, before approaching cautiously.
“Deku? You alright?”
Katsuki saw him tense at his voice, before slowly turning around. When he saw Deku’s eyes his breath caught. They didn’t... look right. He couldn’t quite explain it, but they seemed foggy and it looked like he was in pain.
“Kacchan.”
He watched as Deku painfully swallowed and stumbled towards him. His concern only grew.
“Deku? Do you need to sit down? What the fuck is happening? Were you hit by a quirk?”
Katsuki stepped forward, reaching out, but before he could move anymore he found himself slammed against the floor. The air was knocked out of him and his spine ached from the impact.
“Kacchan.” Deku’s eyes still had that faraway look—his skin was flushed and his lips were parted.
“What-“ gasp “the fuck?” He was wheezing, still trying to catch his breath, when he realized Deku was still pinning him against the ground. His arms were being held down above his head, almost painfully so. He glared up at him with as much fury he could muster.
“What the hell nerd?! Where did that come from?!”
His anger fizzled out when he noticed how Deku was breathing weirdly; he still didn’t look right.
Katsuki took a deep breath, before leveling his eyes with the man above him.
“Deku, get off of me. Now.”
However, the man didn’t listen, only shoving him further into the wooden flooring. He winced in pain, ready to demand again, when he suddenly felt cold air against his legs. His eyes widened as he realized the nerd had ripped his pants and underwear clean off.
“What the fu-“
“Kacchan is so pretty. Kacchan is mine. Pretty.”
The nerd continued to mumble similar things, squeezing his wrists harder every time he moved. That was when Katsuki fully realized the predicament he was in. Taking a shaky breath, he tried to reason once more.
“Deku. Stop it. Right now. Get off.”
But his words seemed to fall on deaf ears, and suddenly something was inside him. It was all wrong. Wrong wrong wrong wrong. He felt like screaming. It hurt.
“Kacchan is the best. So pretty. So strong. Want him. Need Kacchan.”
Katsuki’s eyes were squeezed shut as he tried once more to struggle in vain. He was slammed back down and choked back a sob.
“De- Izuku. Please stop. Please! DON’T DO THIS! STOP!”
His body was shaking, moving with every powerful thrust of Deku’s hips, and he wanted to scream. It hurt and he hated this. He hated how he was so weak. How was he supposed to be number one if he couldn’t make Deku stop?
“GET OFF!”
Every attempt at struggle was shut down. Every attempt at reasoning ignored. He was begging, but Deku seemed to be in his own world—mumbling about his “Kacchan” and how “pretty” he was. How he was all the man wanted and needed.
The pure hot shame that had filled Katsuki to the brim was threatening to spill over. Hot tears were flowing down his cheeks as he took in painful gasps of air.
“Stop. Please. Izuku.” His final plea was barely a whisper, as he slowly accepted that no matter what he did, Deku wouldn’t listen.
He was certain at least one of his wrists was broken. His head was throbbing, his back ached, and everything burned.
And finally, after being pounded into relentlessly for a seemingly endless amount of time, he felt something warm being shot into him. It wasn’t hard to guess what, and Deku’s loud moan as he bit down on Katsuki’s shoulder only solidified the point.
He kept still, trying to tune out everything else and count the number of cracks in the ceiling. It took everything he had to just escape from what was happening and leave the present situation behind. He wasn’t sure he could bear a second round, if Deku hadn’t worked off whatever was done to him. So, he drifted aimlessly in his mind.
Katsuki barely felt when the man pulled out, but for some reason tuned back in when he spoke.
“K-Kacchan?”
His dull red eyes met the now clear and horrified green ones of the nerd above him. Deku looked scared.
The man scrambled to get off of him, stuttering apologies over and over. He flinched as Deku tried to reach out and assess his injuries, causing the man to do the same.
“Oh my God I’m so sorry. I’m so so sorry Kacchan. Are you okay? Can you move? Are you hurt? Shit, of course you’re hurt! We need to get you to a hospital. I- I have to... I-“
Then the idiot burst into tears. At least that was familiar. That was... that was okay. That’s when Katsuki knew it would be okay. Deku was back. He would be okay.
“I’m sorry. I’m so sorry Katsuki. Oh God, what have I done?”
