Chapter Text
4 months after everyone finds out about Katsuki’s swan dive comment.
Katsuki felt vulnerable as he stepped into the dorms after being hit with a quirk.
He wanted to blame his classmates, but how could he? It all started with his stupid comment back in middle school.
Apparently, there had been another student in the room that day, that had a recording quirk. The video of Katsuki telling Izuku to take a swan dive was broadcast over the whole school.
The only reason Katsuki didn’t get expelled was because of Izuku stepping up, well more like bursting into the principal’s office while they chose Katsuki’s future.
Turns out, the threat of Katsuki being expelled was all Izuku needed to turn his embers back into flames. The situation made it hard for Katsuki to be happy about it.
Despite not being expelled, and Izuku defending him, he was quickly shunned by his fellow students. Well, most of them. Monoma still stuck close to him, and his teachers who had been on the battlefield with him didn’t shun him or look down on him.
He assumed anyone who had watched him die knew he had changed, but to the outside world, he understood how it could seem he went into battle for his own ego.
Shoto had distanced himself for a week before approaching both Katsuki and Izuku to sit down and talk about it.
It was clear to the dual hero that Katsuki regretted it and had gone out of his way to make it up to Izuku.
It was because he was being shunned that he got hit with a quirk. It had been him vs four, the rest of his squad had changed their radio station the day they were assigned the patrols.
“K-Kacchan!?” Katsuki felt a jolt of panic run down his back at the childhood nickname. He gripped the jacket Toshinori had given him and pulled it more closed over his new C-cup breasts. Thankfully the teacher still kept on larger clothes than he needed, making Katsuki practically swim in the jacket.
“W-What?” Katsuki snapped as he glared at the nerd. He tried not to react to the other students who looked towards him. A mixture of disgust, hate, and curiosity made his stomach churn.
“Are you okay?” Shoto asked from where he stood beside Izuku. The two had started to step towards him but stopped when they heard the tone in Katsuki’s voice.
“We heard you were in the infirmary.” Izuku wasn’t really deterred by the tone, but he also respected the blond enough to give him some physical distance.
Katsuki opened his mouth to say something, but an image of Deku leaning over him, naked, covered in sweat and panting had him snapping his jaw shut. He could feel the heat of his blush go from his neck all the way up to his ears, and everything in between.
“Kacchan?” Izuku sounded more worried now and took a step forward, only to stop when Katsuki hurriedly took two back. The hurt looks on the nerd’s face constricted his heart. He couldn’t stay there with those thoughts.
“Sorry,” He whispered as he ducked his head and hurried to the elevator. Only, he doesn’t make it.
“Oop, sorry” Kaminari snickered as he stepped out of the elevator and forcefully knocked shoulders with the frantic explosion hero.
It caught Katsuki so much off guard, that he actually spun a little and tripped. He blamed it on the strange body rather than him actually not paying attention.
When he went down, the back of his head hit the floor pretty hard, dazing him slightly.
“Holy shit” Kaminari whistled. Katsuki’s clothes hadn’t fit when he got out of his hero costume, meaning his breasts could clearly be seen through the fabric of his T-shirt.
The extra weight on his chest made it so his belly was showing, and his shorts were hanging low on his hips, now that his waist was smaller.
“Whoa,” Mineta’s pervy voice helped clear the daze from Katsuki’s mind. The Explosion hero let out a loud yelp before pulling the jacket closed again and hurrying to stand.
He should have just run to the elevator, but he turned around to look at everyone.
A few of his classmates had looked away, others looked shocked, but some… some looked at him with smirks or hungry looks.
Despite Izuku being surprised, his face was bright red before he looked away. The nerd adjusting himself didn’t go unnoticed.
Neither did Mineta’s drooling smirk. It made his stomach churn and bile threaten to rise.
He ducked his head and ran for the stairs this time.
~~~
Katsuki had planned on staying in his room for as long as he needed for the quirk to go away, but he was filthy from his fight. He tried to bear with it, but he could feel it every time he moved. It felt like a tight second skin!
Turned out going in the middle of the night was a bad idea
~non-con~
The moment he stepped into the locker room, Kirishima grabbed his wrist in a painful grasp.
“The fuck?” He snarled as he spun on Kirishima, only for the new balance of his body to knock him off kilter, giving the redhead the chance to slam Katsuki on the ground on his front.
Fuck! He didn’t realize girls' breasts could hurt so bad or make it hard to breathe!
“Stick it to the back of his hand so he can't blow it up!” Kaminari was practically bouncing on his feet with a large toothy smile on his face.
“Get the fuck off me!” Katsuki wheezed as Kirishima pressed his leg against the blonde’s shoulders. He tried to struggle, but each movement made it harder and harder to breath.
“Here let me help!” Kaminari chirped before a burst of pain started in his side before spread to his whole body. His muscles tensed and untensed as he was rolled over onto his back. He couldn’t move, and the pain didn’t stop until his arms were pulled above his head, and a purple sticky ball was placed on the back of his hands, keeping them locked together.
When the pain finally stopped, Katsuki sucked in as much air as he could.
“Look! She peed!” Mineta snickered, causing humiliation to run through Katsuki. He felt fucking helpless as the little freak started to yank on his shorts.
“Stop, you fucking-AH!” Another shock ran through him causing his back to arch and his muscles to clench in pain. When it finally stopped, his body went lax.
“Be careful! We don’t want to permanently hurt him” Kirishima’s voice was full of guilt, but he did nothing to stop the little freak from pushing Katsuki’s legs apart.
“You promise not to bit?” Kaminari’s voice was sickly sweet as he grabbed Katsuki’s chin and forced his head towards the electric blond. Despite the pain, and struggle to move any of his muscles, Katsuki spits in Kaminari’s face.
The next electric shock started under his chin.
He must have blacked out, because the next thing he knew there was a cock in his throat, and fingers forcing his jaw open, so he couldn’t bite.
Every thrust had balls slapping against his nose, and his throat constrict as he gags.
He tries to move his arms but the one in his throat had their legs painfully pinning them to the floor.
It took a few seconds for his body to register, the hands on his breasts, squeezing and groping. The lower half of his body is lifted higher than his upper and laying on something softer than the tile floor.
His body jolted when he felt something thick press against his rim. He tried to demand they stop, but it only seemed to bring pleasure to the cock in his throat.
His back arched in agony as his anus was penetrated. He didn’t have much time before a smaller cock was forced into his pussy.
He feels like his insides are being ripped apart as the two thrust in and out in unison.
~~Non-Con over~~
Katsuki has dissociated pretty quickly, only coming back to himself when he realizes he’s alone.
Everything hurt, and he was sticky everywhere. He rolled over onto his side before pushing himself up.
All of his muscles ached from the shocks Kaminari put him through.
Walking felt impossible, but he forced each foot forward. Every step he felt fluids slide down his thighs and legs.
Every time he breathed he could feel the dried fluids on his chest crack slightly.
His jaw hurt so bad and felt locked in his half open state.
When he finally made it to a shower stall, he leaned against the tiled wall and turned on the hot water.
Despite the ball being gone, the back of his hands still felt sticky, no matter how much he tried to scrub it off.
Even after washing everything they left behind he didn’t feel clean.
Unfortunately there wasn’t much he could do about it with the way his body hurt so bad.
He cleaned the best he could before turning the water off and making his way over to his locker. He stared at the clothes inside for several long minutes before turning to Deku’s locker.
He wasn’t sure what possessed him to go over to Izuku’s locker, break the lock and steal the nerd's large ass hoodie and boxers.
He grabbed the collar of the hoodie and brought it up to his nose.
For the first time, Katsuki was glad the nerd had grown a bit. Sure the hoodie was still way too big on Deku, but they were about the same build now and still chose one to two sizes too big depending on the fabric and brand.
The smell of Deku, mixed with all the space in the hoodie, quickly helped quiet the voices in his head.
He had barely noticed the voices until they were gone. Just repeats what his mother used to say.
‘It’s your fault for being so weak!’
‘You should have fought back harder!’
‘you got what you asked for’
He took a deep breath to take in more of Deku’s scent. Once calmed down again, Katsuki made his way out of the locker room.
Chapter Text
It was when Katsuki touched his door handle that he realized he would need plan B. He could barely move with how bad his body ached.
He needed help.
He could go to Monoma and Shinso, the only two outside of Deku and Half-n-half that still talked to him.
His mind drifted to Deku. Deku liked girls. Katsuki liked Deku. Maybe he… maybe Deku could take the feeling of them away. Replace them with him.
Then when he'd ask Deku for help with the plan B pill, he doesn’t have to tell Deku about what happened. He didn’t want to tell Deku he was weak.
~~
He stood outside Deku’s room, gripping at the chest of the hoodie. He wanted to knock but what if Deku was still with round cheeks?
He vaguely remembered him talking to half-n-half about them breaking up because she wanted him to stay away from Katsuki.
Did he really want to be the reason for their relationship to be more strained?
Before he could back out of it, the door opened.
“Kacchan?” Deku yawned lightly, rubbing at his eyes.
It was now or never.
Katsuki reached forward, and got fist full of Izuku’s night shirt. He yanked the nerd towards him so their lips could meet.
“Ka-mm” Deku barely hesitated before his stupidly big hands were on Katsuki’s hips, pulling him closer.
His face was heating up as the kiss was deepened. Katsuki needed to get them into the room instead of standing outside where anyone could see them.
Deku didn’t fight him as he pushed the nerd into the room, just kept a tight hold on his hips to keep the kiss going.
Katsuki kicked the door closed behind him before roughly pushing Deku down on the floor. Of course, the Nerd dragged him down with, only letting their lips separate for a couple of seconds.
Katsuki leaned up a little from where he straddled Deku’s hips, so he could pull the boxers off, one leg at a time.
“Ka-mmm-chan” Deku moaned out as he was straddling again.
“Shut up, nerd” Katsuki mumbled with no heat, against Deku’s lips.
Deku let out another loud moan when Katsuki reached between them to pull the stupid thick cock out of Deku’s night shorts.
Fuck, it was so big he had to pull away from Deku’s lips to look down at it.
“Holy shit. How the fuck do you hide this thing!?” He asked as he gave it a few strokes. Not that it needed it, Deku was full mast and ready to go.
“Kacchan” Deku whined. When Katsuki looked up at him, he had to stop to take in Deku’s beautiful features.
His face was flushed, showing his freckles even more, all pulled together with his soft lips, and bright eyes. Even with just the moonlight shining through the window.
“Fuck you’re beautiful.” Those green eyes went wide, and his cheeks got even redder. His eyes fell half lidded.
“This has to be a dream” Deku mumbled softly, causing Katsuki to snicker.
“Maybe.” He whispered seductively as he leaned back down to begin their kissing again.
Katsuki positioned himself, so the head of Deku’s cock was pressing up against his pussy. He pressed down until the head finally slipped in.
“Oh, gods!” Deku gasped before gripping Katsuki’s shoulders and pushing him up slightly. “Wait, that feels real. Is this real!?”
“Deku” Katsuki let out a small whine as he wiggled his hips, slowly moving the cock deeper. He was bigger. It felt like it was carving a place inside him. It would only fit Deku.
“Wait,” Deku gasped softly when he finally bottomed out. Katsuki’s mouth opened in soft pants, as his pussy pulsed with pleasure around the cock. It was crazy how different it felt now.
“Stop!” Deku said a little snappier when Katsuki tried to lift up a little. It was only when Deku’s hands dug into the bruises on his shoulders painfully, that he stopped moving.
He grits his teeth, doing his best to keep his tears from falling.
He hated pain. He thought pleasure and pain were supposed to go hand in hand. But he fucking hated it, it made feeling the pleasure that had been there impossible.
“What!?” He hissed back as he shook his shoulders free. It wasn’t Deku’s fault, he reminded himself. Almost all of Katsuki’s body was covered by the hoodie. From head to mid-thigh. The bruises on his legs, thankfully, couldn't really be seen in the semi-dark room.
“If… If we do this, it can't be a one-time thing. If we do this, it has to be as a couple.” Katsuki’s heart clenched. Was Deku asking him out?
“Are you asking me out?” His voice was quiet with anticipation. Deku blushed again and looked away.
“I mean, you wouldn’t be here doing this if you didn’t at least like me a little bit. A-And I’ve… I’ve loved Kacchan since we were little. But if you don’t want to I get it. Maybe its just being quirked that makes you want to be h-“ When Katsuki got his breath back from Izuku’s confession he leaned down and silenced him with a kiss.
“I love you too” Katsuki whispered against Deku’s soft puffy lips. Before the nerd could start his crying fest, Katsuki leaned back up, placing his hands on Deku’s abs and rose.
The pleasure was back, and it was insane. Katsuki tossed his head back to let out moan after moan as he began riding Deku with more speed and power.
He barely noticed when one of Deku’s hands laid on his hip, But the sudden shock of pleasure when Deku slid his fingers over the nub at the top of his pussy, he definitely noticed.
His body curled forward as he desperately tried to keep riding with the new stimulation. It was too good.
“Oh fuck, oh fuck! D-Deku!” He cried out as his muscles tightened. His toes curled up as Deku kept rubbing the nub.
He couldn’t bring himself to keep moving as his legs began to twitch and shake, the pleasure in his pussy quickly fading to a strange pain he’d never felt before.
Was this the pain they talked about? It felt good!
“you’re squeezing me so tightly, s-should I stop?” Deku panted out. He couldn’t seem to open his mouth, so instead he shook his head no.
Deku didn’t stop until Katsuki’s pleasant pain burst into body numbing pleasure.
“You squirted” Deku whispered amazed as Katsuki sucked in deep breaths, his legs twitching uncontrollably as Deku’s boxers and the bottom of his shirt got soaked. When his muscles finally relaxed, he had no choice but to drop weightlessly onto the smaller teen.
Deku’s large hand slid under the back of his hoodie and rubbed gentle circles into Katsuki’s back.
It took a minute for Katsuki to realize Deku hadn’t cum yet. Which was perfect given Katsuki wanted to erase all evidence of them, which included Deku’s massive cock carving out his rectum.
When the blond started to pull up, he had to bite into Deku’s skin to keep from crying out. He had never felt something so confusing before in his life. It felt amazing, but hurt at the same time. He couldn’t decide if he wanted it to continue or stop.
Thankfully he didn’t have to think about it when it slipped out. When the blond let go of Deku’s shoulder he received gentle kisses to his hoodie hidden face.
“You did so good, Kacchan” Deku whispered with pride in his voice.
It made Katsuki’s face warm, and something in his belly flutter.
“Kacchan!” Deku gasped when he felt Katsuki’s smaller hand wrap around his still rock hard cock. “You don’t have to, I’m okay as long as you're satisfied.” Normally Katsuki would make vomiting noises at something so sickeningly sweet to try and avoid the feelings it brought up. But in the privacy of Deku’s room, he let that giddy happy feeling seep into his abused skin.
“Wanna” Katsuki whispered softly as he leaned his lower half down.
Despite what he went through earlier, getting the head of Deku’s cock in his ass hurt badly, he let out a sob.
“Wait,” Deku’s voice was gentle and caring, as his large hands made their way to Katsuki’s ass. He could feel Deku tense up under him as the blond whimpered when fingers ran across his rim.
“Kacchan?” Deku whispered as he pulled his hand away, moving it closer to his face so he could see it in the moonlight.
They must have aggravated one of the tears into splitting open again, because Deku’s finger was covered in blood.
“Oh gods we need to stop!” Deku gasped, only for Katsuki to growl, grip at the nerd’s shirt and force himself down until the cock was fully embedded.
It wasn’t as bad as it had been the first time, he’d been opened up, but it still hurt like a bitch.
“Kac-“
“No! Shut up!” Katsuki snapped as he dropped his head to hide the tears. He needed this. When he thinks about this aching pain, he needs to think of Deku, not… not them. “I…I need this” His voice came out like a whimper.
“Okay” Deku whispered as his hands slid up Katsuki’s thighs, under the hoodie and gently rested on the blonds hips. “Just go slow okay? I don’t want you to get hurt.” Thumbs, probably meant to be comforting, painfully rubbed the bruises.
On anyone else, the abuse might not have bruised so easily, but Katsuki took after his mother. It was also the reason he bled so much.
When Deku felt the flinch he stopped moving his thumbs.
Katsuki slowly lifted himself up, biting his lip to keep from whimpering.
He started at a slow pace, trying to avoid as much pain as he could.
Unknown to him, Deku sent out black whip to wiggle around Deku’s cock, and play with the head, while another slipped into Deku’s ass to find his prostate. The speed Katsuki was moving would take Deku way too long to cum, but he was worried about Katsuki’s health. He felt no guilt in his attempt to speed up his own orgasm.
When Deku’s abs tightened under Katsuki’s hands, and he felt the cock inside him twitch before feeling a rush of warmth, Katsuki let out a heavy sob.
That one made way for the full blown breakdown that came next.
Deku leaned up and wrapped his arms around Katsuki’s waist and hugged him, as the larger boy thumped his forehead against Deku’s shoulder.
Chapter Text
It took almost 20 minutes for the blonde to finally stop crying so hard he thought he would die.
He had never felt so exhausted in his life before. He wanted to crawl into Deku’s bed and sleep forever.
“Kacchan, we don’t have to talk about it now but I would like to know what’s wrong.” Katsuki hummed in response. He wondered if Izuku would let him crawl into his All Might bed, bleeding and probably leaking. Only one way to find out, he thought.
He gently pushed Deku’s hands off his hips before standing up. He hurt pretty bad, but some of the emotional turmoil was gone, knowing Deku was the cause of it. He turned and tossed back Deku’s blanket before crawling in. He scooted all the way towards the wall before pulling the blanket up past his shoulder.
As he dozed, he was barely aware of Deku crawling into bed. Deku pulled the blanket and moved it around so Katsuki’s ass was exposed.
Katsuki didn’t fight or complain when the nerd lifted one of his legs to examine and clean him up.
“What happened to you” Deku whispered, not really talking to him, but to the empty air around them. “This couldn’t have been all me.” Katsuki flinched when he felt something cold against his rim. “Sorry, baby” Deku cooed. It made Katsuki’s belly flutter again.
So, they were dating now, Katsuki guessed. He felt like a giddy fucking school girl. He gripped the hoodie and pulled it up to his face to breathe in the smell of the hoodie.
Wait, does that mean he has to change who he is? Does he need to change how he acts and reacts? Oh fuck, what if Deku gets tired of him? He wasn’t sure he could go back now. If he fucks up, Deku wont just ignore him for a few days, he’ll be gone.
He didn’t notice when he was rolled over, or when Deku talked to him. He did notice his hand being placed on Deku’s chest as he took exaggerated breaths. It made him realize he was panicking.
He sucked in when Deku did, breathed out when he did, until the sound in the room came rushing back.
“What happened?” Deku asked as he lowered their hands, but never really letting go of Katsuki’s.
“I…” Katsuki’s voice was raspy, and despite being bigger than Deku in ALMOST every way, he felt small. So small and fragile. Katsuki used his free hand to rub at his eyes, the sleeve soaking up the tears he had yet to shed. “Are you… are you sure you want me?” Katsuki felt sick once the words left his lips. Why was he so weak all of a sudden? He never let people see his doubts and fears.
Deku just smiled softly at him before laying down next to Katsuki. The blond rolled over so they were facing each other, hands still grasped between them.
“Kacchan, I’ve loved you since we were kids. You’re all I’ve ever wanted.” Katsuki whimpered before lifting his free hand up to his face again, scrubbing at the tears.
“I-I love you t-too” Katsuki hiccupped before Deku wiggled closer to pull Katsuki down so the blonds head was against Deku’s chest.
Katsuki couldn’t stop the chuckle when his feet hung off the bed due to being tall.
He liked how Deku was treating him, despite their differences. Anyone on the outside might assume Katsuki would be dominant in their new found relationship, just based on their body differences.
They were almost dozing off when Katsuki remembered one of the reasons he showed up to Deku’s room. With his forehead pressed to Deku’s chest he spoke quietly.
“I need plan B” For a minute Katsuki thought the other teen had already fallen asleep, but then Deku was hugging him tightly, his nose in Katsuki’s hair.
“Okay, We can get it in the morning” Katsuki knew Deku was smart enough to connect the dots.
From the bruises he had actually seen, to the tears in his rim, and the need for plan B, it should be easy enough for Deku.
Comforted by the fact Deku pulled him closer instead of pushing him away, Katsuki slid his arms around Deku’s waist and let himself drift off to sleep.
~~~
Katsuki was woken up a couple of hours later by Deku gently shaking his shoulder.
“Hey, can you sit up for me? I have the pill and a cup of water.” Deku said as Katsuki shifted around so he could look up at the nerd. The moment their eyes met, Deku went pale, even in the sunshine that bled through the blinds.
“What?” He rasped. Deku’s eyes hardened before he looked away.
“I couldn’t see the bruises last night.” He mumbled as Katsuki worked to sit up. His whole body hurt and ached, causing him to wince occasionally.
“Well, you haven’t seen ‘em all yet either.” He mumbled back as he reached out for the pills.
When Deku put the pill in his hand, Katsuki stared down at it, like it was a puzzle he was trying to figure out.
Deku watched as Katsuki began glaring at the pill before tossing it into his mouth and taking the water. Katsuki drained the cup before pushing it back at Deku.
No more than a minute later, Katsuki was leaning forward slightly, groaning as his body shifted and changed back to male.
“Thank fuck” Katsuki smiled over at Deku. His belly fluttered again when Deku smiled back. His eyes focused on Deku’s pink lips and thought about how amazing it felt to kiss and be kissed. His eyes returned to Deku’s eyes when the other teen chuckled.
“W-What!?” He snapped, not that it was very effective with his face as red as a tomato.
“You can kiss me anytime you want, Kacchan.” Once the words leave his mouth, Katsuki practically throws himself at the nerd. Who squeaks before giggling into the kiss.
Deku spread his legs to let Katsuki position between them. Where he gently rutted his hardened cock against the soft material of Deku’s shorts.
Fuck, he had missed having a cock.
It was a new feeling when Deku pulled his own cock out and gripped them together.
He liked the feeling, but something felt off. It took him a minute of trying to focus to realize, he much preferred when Deku was on top of him.
Katsuki gripped Deku’s hips before rolling them over, ignoring the yelp from the smaller teen. Katsuki then moved his legs around until they laid outside Deku’s legs.
“Are you sure?” Deku asked. The question had Katsuki second guessing himself.
Did he want to be submissive in this moment because he actually wanted it, or because it’s easier, and the only thing he’s really experienced?
It was embarrassing when it actually took him a minute to reconnect with his fantasies before the quirk accident.
“Yeah, I’m sure” He whispered softly before leaning up and capturing Deku’s lips again.
It was Deku’s turn to rut into his hand, sliding along Katsuki’s own cock.
Katsuki winced slightly when he felt Deku’s hand moving up his side. He had handprint bruises all over his sides.
Thankfully Deku didn’t stay on his side as long as he made his way up to Katsuki’s pec and began to gently grope it.
He was slow and paid attention to every twitch of Katsuki’s cock. When he found the blonde's nipples were sensitive he focused on it.
“D-deku!” He whined as he squirmed under the other teen. “I-Imma cum!”
“Already? I’ve barely done anything yet!” Izuku giggled. It caused a small tingle to run up Katsuki’s spine, which pushed him over the edge. His hands tightened in the blankets under them, his back arched and his vision whited out for a couple of seconds.
When he came back to himself, it was to gentle kisses to his cheeks and forehead. Katsuki let out a content sigh as he turned to catch Deku’s lips.
Katsuki hooked his hands under his knees and pulled his legs back and open.
“It’s your-“
“Midoriya!” Katsuki’s whole body seized up at the sound of Kirishima’s voice.
“Baby?” Deku whispered, his hand coming up to cup Katsuki’s face. It was enough of a distraction for Katsuki to relax. He let go of his legs and gently gripped at Deku’s arms, which were caging him in.
“Midy-bro!” came another call, this one panicked and followed by a fist slamming on the door.
Katsuki’s stomach churned, his body heated up and his throat felt like it was swelling. Despite no longer having a pussy, he could feel the ache of being penetrated for the first time, dry except for the blood from his hymn.
He felt the ache in his ass and back.
He barely managed to throw himself away from Izuku before vomiting. He gasped and shuddered.
Again he found himself crying. And again he found Deku, gripping his face and turning his head to look into his green eyes.
Scarred thumbs rubbed under his eyes to clear away the salty fluids. It only took a couple of seconds of looking into his red eyes for Deku to understand.
He had never seen Izuku so MAD before. Determined, frustrated, focused but never this mad.
“Wait” Katsuki whispered as Deku got off the bed. He tucked himself away before stomping over to the door and yanking it open.
“Hey! There's blood in the sho-“ He didn’t get to finish as green lightning sparked up Deku’s skin. Katsuki watched as the nerd pulled his fist back. He saw the moment Kirishima understood what was about to happen.
“Shit” Katsuki whispered as he got off Deku’s bed, just as the nerd launched himself after the punched redhead. There were other students in the hallway. Some trying to get Deku off Kirishima, the others staring at Katsuki with a mix of shock and disgust.
The blond quickly whipped his face clean with a fresh washcloth Deku had left on the side table, before digging through Izuku’s drawers to find a pair of boxers for himself.
“Hey, Kacchan! I don’t think Midoriya would appreciate a whore like you going through his things!” Katsuki’s hands stalled as he looked up at Kaminari, who had stepped into the room.
Katsuki could feel the electric pain running through his body again. The painful burns as it made its way through his system.
Why was he so fucking scared!?
He'd kicked the electric teen’s ass a million times.
Despite that, he was frozen to the stop.
He couldn’t move as Kaminari walked over to him until they were an inch apart.
“If you tell anyone else, I’ll have to tell everyone how much you loved it. How you swallowed down our cocks one at a time until your pretty little face got all bruised up.” Katsuki shudders with fear as the other blond grips his chin. “How you begged us to fuck your pretty pink pussy until your thighs bruised. How you needed more than just one hole stuffed at once or you’d go crazy. Tell them how you presented your filthy ass to us, pulling your cheeks apart to expose it twitching in want.” Katsuki flinched slightly when Kaminari ran a staticky finger along Katsuki’s jaw. “Tell them how badly you begged us to use our quirks on you. And then finally, were going to tell them how you still didn’t have enough so you had to go to Midoryia and fuck his brains out, while feeding him lies. You understand, Kacchan”
Katsuki felt so small again. Not the same fuzzy feeling he got with Deku. Something dark that pulled all the fire in him down, until it was snuffed out.
His mouth was dry and wouldn’t open, so he nodded instead.
After that it was like a switch had been flipped. Happy go lucky dunce face was back, smacking Katsuki’s face before turning and leaving.
While they had been talking, or well, while Kaminari was talking the fight had moved further away from the doorway, taking the crowd with it.
Katsuki had originally meant to stop Deku from getting into trouble, but when he finally got the boxers and stepped to the threshold, he just couldn’t seem to make himself pass it.
He screamed and yelled at himself, but his body just wouldn’t move. He turned back and looked at the state of the bedroom and figured maybe his time would be better spent cleaning up.
Chapter Text
By the time Izuku finally returned to his room, he found Kacchan back in his bed, and the room spotless.
He sighed softly when he looked at the clock. He had spent the whole day being lectured, and hadn’t really noticed.
As he went about his nightly routine he wondered if Kacchan had eaten while he was gone, or if he had done anything other than cleaning.
When he was ready for bed, he pulled the blankets back and crawled in, pressing his chest to Kacchan’s back, and burying his face in the back of his golden spikes.
“Kaminari threatened me” Kacchan whispered softly.
“With?” Izuku whispered softly pressing gentle kisses against Kacchan’s nape. He was angry, but knew Kacchan needed love and attention not rage and anger.
“To tell everyone I wanted it. He said some nasty things, made me feel… dirty.” He whispered. Kacchan gripped his hand and pulled it against Kacchan’s chest, hugging it to him.
“We need to get ahead of this.” Izuku whispered. “We should go to recovery girl, start the process of pressing charges.” He felt Kacchan tense up against him. “I’ll be with you every step of the way” When Kacchan started to turn over so they faced each other, Izuku held his arm up, so when the blond was settled he could lay his arm over Kacchan’s waist.
“You.. you know I didn’t want it right?” Kacchan sounded so vulnerable, his smaller hands gripping tightly at Izuku’s night shirt.
“Of course I know, Kacchan! No matter what they say, I'm not going anywhere.” Kacchan leans up and presses their lips together.
“Can we go now?” Kacchan whispered into Izuku’s lips.

Katsuki stood outside the infirmary, hood pulled over his head, sleeves pulled down over his hands. He insisted on going back to his room and grabbing a pair of black sweats.
So there he stood, covered from head to toe, trying to get control over the rate of his heart as Deku knocked on the door. He wanted to hide behind Deku when the door opened.
“Can I help you, two?” Asked the small woman. Her eyes glanced away from Deku before zeroing in on Katsuki’s form.
“Can we talk inside.” Deku asked. Katsuki watched the smaller woman straighten up and nod before stepping to the side. He ducked his head as he followed Deku inside.
“Is this in regards to the quick accident I heard about?” She asks as she steps over to her desk, waving at the bed.
“Yes Ma’am” Deku said. When Katsuki didn’t move, Deku slid a hand behind Katsuki’s back and encouraged him to move over and sit.
She let out a soft sigh before looking at Katsuki with a sympathetic look.
“Did you shower?” She asked. Katsuki was slow to nod. “Have you returned to your male form?” Katsuki nodded. “The next few questions might be… sensitive, if you would like, we can have Mr. Midoryia return to the dorms.”
“No!” Katsuki panicked, his hand reaching out and snatching Deku’s. Feeling the smaller teen’s thumb rub gently at the back of his hand helped some of the nerves.
She eyed the hands for a moment before nodding and turning back to her desk.
“If we continue, there won't be any backing out. Once the predators are caught, you may be required to testify in court. Knowing this, do you want to continue?” She stopped typing to look at Katsuki.
The blond gulped before hesitantly nodding.
Chapter Text
Aizawa was called in for a second set of eyes.
It was emotionally stressful for Katsuki when he was asked to walk them through what happened.
When he was done, he avoided all three sets of eyes.
“The next step is pictures” Recovery girl said slowly and gently like he was as fragile as glass. Katsuki expected himself to be angry, but it made him feel a little better as he stood up and pulled off his hoodie.
They took pictures of the bruises that laid over his cheeks and nose. Of the bruised handprint on his throat, he didn’t remember getting it.
Katsuki could feel the air vibrate with static as Deku tried to contain his anger when they moved on to his chest. It was covered in bite marks and hickeys. The worst were the burn marks that branched off of his nipples.
The burns went down his ribs, several marks here and there.
He had scratches and cuts from Kirishima’s inability to control his quirk.
He had what looked like an infected bite on the inside of his arm.
“Sodomy?” Aizawa asked, his tone slightly angry as Katsuki slowly pulled his sweats off. Katsuki tried to hold the tears back as he nodded. He felt more exposed then he had ever been before.
“I’ll need to check for tearing.” Recovery girl sighed from where she was taking pictures of Katsuki’s thighs.
“There are tears. Is there any way we can…skip that part?” Deku asked. The two adults looked at him with a mixture of suspicion and accusation.
“He… we…” Katsuki gulped. “After, I pushed… Deku to have sex” He whispered.
“You didn’t push anything” Deku sighed before leaning down to help pull the blonde’s sweats back up when Recovery girl was done.
“It’s common for victims to try and replace the bad with a good experience. I don’t need to check if you’ve seen them.” Recovery girl said as she returned to her desk to log the pictures.
Deku helps Katsuki with his hoodie as the two adults talk.
“Thank you” Katsuki whispered, a light blush on his face when Deku gently held his shoulders, so they were facing each other.
“Anything for, Kacchan” He had never felt so loved before. It was weird, but a good weird. Katsuki’s shaking hands wrapped around the smaller male’s hips as he leaned his head down to press their foreheads together.
“You two stay here for the night, while we escort the three off the premises.” Aizawa said before leaving.
“Give me your hand, deary.” Recovery girl said as she made her way over to Katsuki. The two boys let go and turned to her as Katsuki did as she asked.
The moment her lips touched his skin, his world went dizzy, before going black.
~~
Izuku quickly caught Kacchan before he had the chance to fall.
“Hm. Must have had some injuries we couldn’t see. He should sleep through the night.” She said as she lightly patted Izuku’s arm.
“Thank you, recovery girl”

Kirishima ended up confessing, after a small guilt trip from the police.
With his confession, and the evidence Katsuki supplied, the three were put in the juvenile correction center.
For the safety of all teens involved, their names were kept out of the press.
At first the rest of the students continued to shun him except for Shoto. Even more now that they believed it was his fault three of their classmates were taken away. Of course none of them truly knew what happened. Aizawa and the police left it up to him who he told.
He wasn’t ready. Not until he found some of the other students harassing Deku about him, while the nerd attempted to cook him and Katsuki food.
“Why are you slaving over food for him!?” Uraraka complained.
“Yes, I must agree! How could you take care of someone who tortured you!” Iida chirped out.
‘Take care of’
He wasn’t technically wrong. Katsuki had slipped into a depressive state and needed help with simple day to day tasks. Katsuki had no problem beating up villains, doing his schoolwork or training, but simple tasks like eating, changing his clothes, and regulating his sleeping schedule were difficult for him. Don’t even get him started on the shower. The first time he tried on his own he went into a full panic attack. Even after training or working out, Katsuki couldn’t do it on his own.
At first it was embarrassing to get in the shower with Deku with all their male classmates gawking, but it didn’t take long for the nerd to distract him.
“Based on the noises in the showers, you do more than just take care of him” Grumbled Tokoyami.
“Deku, if you’re not careful, you’ll be the next one kicked out because of him.” Uraraka said. Katsuki grits his teeth at her words. He was about to walk around the corner and start yelling, but Shoto grabbed his arm and raised a finger to shush him.
“They were kicked out for good reason. None of us have to worry.” Izuku sighed as he moved the food from the burner to the counter.
“Wait, you know the reason?” Mina asked.
“Does it have something to do with his newfound laziness?” Uraraka huffed. Katsuki could instantly feel the static spiking in the room.
In the beginning, Katsuki had been triggered by the static, but exposure therapy helped him focus on the difference. Now every time he felt it, his spine would tingle, his cock would weep, and his hole would twitch. When the static started, it meant Deku was getting serious and usually led to mind numbing pleasure.
“He’s not lazy” Deku’s voice was deep and gravely with anger, Katsuki had to cover his mouth to keep from moaning out. He could see Shoto arch a brow out of the corner of his eye. Katsuki was glad he had one of Deku’s large hoodies on to keep his boner hidden.
“Sure, he’s not” Uraraka rolled her eyes. “The only thing he does is train and do internships. He doesn’t cook; he doesn’t clean hell he needs you to take a fucking shower!”
“They raped me!” Katsuki isn’t sure why he stepped out and yelled it. He couldn’t stop. “The purple fucker used one of his fucking balls to stick my hand together before they fucked me, over and over, even after I started bleeding!” He screamed tears starting to swell. Shoto was beside him, holding his hand and looking at him. Katsuki’s shaking hand lifted up his hoodie, His boner long gone, to expose the streaks from Kaminari’s quirk. “They scarred me for life! I can barely get up in the fucking morning!” Deku was walking over to him as he dropped the hoodie back down. When his boyfriend wrapped his arms around his waist, Katsuki wrapped his free arm around Deku’s shoulders and buried his face in the shorter teens neck, trying to get control of the emotions running through him.
“The blood in the shower room was yours?” Iida whispered with surprise.
“Kirishima, Kaminari and Mineta didn’t just get kicked out, they were sent to a juvenile correction center.” Shoto sounded angry. Katsuki wasn’t sure how much half-n-half knew, only that Deku asked if he could talk to someone about it. Figuring it affected Deku too, he agreed.
Katsuki let out a whimper he was trying to hold back as the dam broke. He had been doing so good, not thinking about it, but now it felt like it was filling every crevice of his mind.
The blond didn’t fight as Deku leaned down, slipping his arms around the back of Katsuki’s knees and hoisting him up, to straddle his waist. Katsuki let go of Shoto’s hand to wrap both arms tightly around Deku’s shoulders as he was carried away.
~~
After that things got… easier. The first day back at school after his blow up, everyone treated him like glass, which ended with him kicking all their asses in training, then screaming about how he most definitely wasn’t glass.
He was with Monoma the next time he got triggered. They had gotten closer, and Katsuki truly considered him a friend.
One of the freshmen had some kind of electric quirk, and just the sight of the sparks had his world spinning.
He has no memory of what happened after that, but he woke up in the infirmary later, his hands tied to the bed, and explosion scars on his arms. Apparently, he had tried to self-destruct.
Aizawa forced him into therapy after that.
He went every other day, instead of once a week like usual, something about him being a future hero, and needing to move past it before graduation.
Which, you know, no pressure.
After seeing her for half a year, they tried more exposure therapy, through their summer break.
Katsuki had decided to stay in the dorms for the summer, and of course Deku chose to do the same. Inko visited them every day. At first it was a struggle because she had learned about the comment he had made to Izuku when they were younger, but once they all sat down and had a conversation, she was able to look past it. He wasn’t sure if she had forgiven him or not.
The following year was their last, and it was difficult for Katsuki. Everyone was talking about graduating and becoming sidekicks while Katsuki still had to get past his demons.
It got easier after Kaminari escaped and showed up, accusing Katsuki of ruining his life. At first Katsuki felt like his world was crumbling, and he struggled to do anything but dodge attacks.
When a bolt of lightning just barely misses him and a small child, Katsuki’s brain switches gears. He’s supposed to be a hero, and here he was willing to let civilians, children even, take the hits as long as he didn’t have to.
After that, it was easy for him to take Kaminari down.
The rest of their last year, Katsuki silently stressed about which agency he would go to, and how he would handle being away from Deku.
Turns out, he didn’t need to worry. On the day of his graduation; he, Shoto, and Deku were bombarded with offers.
“Deku, can we talk?” He asked right after the ceremony.
“Of course Kacchan!” Deku chirped happily as he followed the blond to a secluded area.
Once they were away from prying eyes, Katsuki stepped into Deku’s space, his hands pulling gently at Deku’s graduation gown.
“I know we’re not supposed to base our life decisions on other people, but i-“
“Kacchan” Deku stops him with a small smile, his stupidly big hands wrapping gently around Katsuki’s waist. “I will follow you anywhere.” A giggle slipped past the nerd's lips when Katsuki just stared wide-eyed and red-cheeked.
“I love you” Katsuki whispered once he got over his shock.
“I love you too, forever and always”
