Chapter Text
“Please Deku- I swear I just need a few minutes please-”
“Kacchan?! Oh my god stop-” Izuku practically squeaked, his face heating up as he looks anywhere but his best friend, who’s currently kneeling in front of him where he’s sitting in the living room.
The blonde shuffles forward slightly, his hands wrapping loosely around Izuku’s ankles while he nuzzles against his knees, which are pressed together in embarrassment.
While Katsuki continues to beg, Izuku feels his eyes start to burn, tears slipping down his cheeks as he tells him to stop to no avail.

“Oh shoot-” Izuku stumbles as a civilian runs straight into him, before turning to apologize but instead dropping to his knees with a groan as the man looks back at him in horror, rushing to his side with frantic apologies.
Izuku hears none of them, the pain burning through his abdomen causing ringing in his ears as his eyes roll back and he slumps to the pavement, unaware of the civilian already on the phone with dispatch and explosions rapidly getting closer.
He wakes up with a start in a white hospital bed, looking around frantically before his eyes land on his mom and Kacchan sitting by his bed. He feels comforted by his moms presence, but immediately cringes at Katsuki’s presence.
Things between the former friends had been strange lately. Izuku was trying to put up boundaries, feeling a little creeped out by the strange advances the blonde had been trying recently. Such as hands creeping up his thigh, a brush of his palm along the other's ass, just things that made Izuku squirm and jump away with an ugly feeling curling in his gut.
Of course, since Izuku is Izuku, he hadn’t said anything directly to Katsuki, just expressing light disgust or discomfort, but all that seemed to earn was a satisfied smirk in his direction.
So yeah, seeing Kacchan nowadays made him nervous.
“Oh Izuku baby!” his mom yelps, rushing forward to grab his hand and as Izuku shifts to meet her, he immediately knows what's wrong. His upper thighs brush against each other effortlessly, but that's not what clues him in… it's the fact that there's nothing between them.
Izuku freezes with a small squeak, watching his moms eyes soften with worry and understanding at his reaction. He’s careful to not look at his other visitor, scared of what he might see. Instead, he keeps his watering eyes on his mom as she explains the quirk he was accidentally hit with.
The man that had done it was very apologetic, insisting he didn’t mean to activate the quirk, and willing to give the details on what it would do. Obviously, it switches the victims genitals, but only in the lower areas. It’s unclear on how long it’ll last, could be 2 days, or 2 weeks, but it’s not permanent.
He lets out a small sigh of relief at that last part, not wanting to deal with female parts for the rest of his life, for how weird it would be, not to mention the intense feeling of wrongness.
Other than the explanation of the quirk, the only thing they were keeping him for was so he could wake up in a stable environment, with his vitals under observation, so now that he’s awake he’s all good to head home.
Izuku’s mom apologizes profusely, having to leave before her son to get back to work. He’s, of course, understanding and sends her off with reassurances, but immediately feels uncomfortable once she walks out the door, leaving him with Kacchan.
He meets those red eyes for the first time since waking up and almost flinches at the intensity swelling in the depths. That, paired with his smirk is enough to speed up Izuku’s heart and he quickly looks away.
“Thanks for coming Kacchan, I can get home on my own,” Izuku says with a slight wobble, keeping his eyes on the ground as they stand outside the front doors of the hospital.
Katsuki just grins and pulls out his keys. “Don’t mention it nerd, and I brought my car, so I can give you a ride,”
Izuku shrinks in on himself slightly, a shaky and unsure smile on his lips as he shuffles after Katsuki on their way to his car. He slides into the passenger seat, sitting ramrod straight as the car rumbles to life and they shoot out of the parking lot.
Kacchan’s always been a fast driver, pulling maneuvers that make Izuku a little green around the gills, but today it seems a little gentler, which Izuku is grateful for as his stomach is already twisted with anxiety at his predicament along with being alone with the blonde.
As they slow to a stop at an intersection, Izuku lets out a small yawn, looking out his window for a moment, only to jolt and whip his head back around as a large hand lands on his upper thigh. His eyes flick up to Kacchan's face as he tries to shift away, but Katsuki’s hand just tightens slightly, keeping his leg in place.
Izuku feels that now familiar feeling curling in his gut as tears prick at his eyes. Normally he can deal with this, but on top of everything he’s been through this day, it’s just too much.
No matter how he feels, that hand stays right where it is for the rest of the ride, only lifting as Katsuki reaches to turn off the car and get out. In Izuku’s dissociation, he doesn’t realize that he’s been followed from the car until he’s at his door.
He turns to look at Katsuki, flinching at his gaze, feeling as if he has filth coating his skin everywhere those red eyes trace.
“Gonna invite me in, nerd?” he shoves past Izuku despite the question, leaving no room for argument as he slumps onto Izuku’s couch.
Dumbfounded, Izuku just stands at the front door for a second, staring at the relaxed manner in which Katsuki relaxes in his space, like it’s his house too. Now, don’t get him wrong, with most of his friends he really wouldn’t mind them inviting themselves in, but something about seeing Katsuki do the same makes him squirm.
Izuku takes a moment to collect himself before shutting the door and trudging fully inside, muttering about a shower as he passes Kacchan on his way to the bathroom.
He strips and gets in the shower quickly, but not before he locks the door, feeling nervous with Katsuki right outside. Still, he lets the scalding water wash away the imaginary filth as he cries silently, wishing he could just be alone to process what’s happened to him. Even if his situation is temporary, it still feels monumental and wrong.
As he steps out of the shower and dries off, he can’t help but pause to listen, hoping that Katsuki’s left, no matter how slim a chance it might be, but his hopes are quickly dismissed at the sound of the TV, the soft chatter drifting through the walls and weighing heavily on Izuku.
He steps out of the bathroom quietly, dressed in baggy sleep shorts and a worn out t-shirt as he slips into the living room, sitting as far away as possible from the blonde as he can on his small couch.
Sure, he’s a hero, but he’s never really had the need for luxuries like a huge house or fancy furniture, and honestly he loves his house, but right now he really wishes his couch was 20 feet long.
The only acknowledgement he gets from Katsuki is a brief glance before he sits up and turns off the TV, his sudden movements making Izuku jolt slightly.
No words are said as he slinks off the couch, dropping to the ground and shuffling in front of him. Izuku clenches his legs together, his jaw clenching as a whimper threatens to crawl from his throat. That disgusting feeling twists in his gut again, a cold sweat breaking out on the back of his neck.
Katsuki doesn’t touch him yet, no he just hovers menacingly, eyes full of promises that feel a lot more like threats the longer Izuku looks.
“Can I see?” the words drip from his tongue, making Izuku flinch back with a look of fear.
“What?! Kacchan-”
“‘Zuku just hear me out, I need this-”
“No!”
“Please Deku- I swear I just need a few minutes please-”
“Kacchan! Oh my god stop-” Izuku practically squeaked, his face heating up as he looks anywhere but the man kneeling at his feet.
The blonde shuffles forward slightly, his hands wrapping loosely around Izuku’s ankles while he nuzzles against his knees.
