My Hero Academia |  Bakugo Katsuki x Kirishima Eijiro 

Kirishima, all his life, has been an open book. No topic was too serious or taboo for him to engage in, as long as he had something to say, he would say it. If anyone asked him a personal question he would answer it honestly and openly. That is unless it was about one thing. Why he never seemed to use the bathroom anywhere outside of the safety of his own bathroom.

When he was in highschool, at UA, was the first time he had to deflect questions about this. When the dorms were built and his parents agreed to let him move in, they had one condition: He had to have a personal en suite bathroom in his dorm. Aizawa and All-might were more than understanding when, against his will, Kirishima’s parents told them about his condition, his painfully shy bladder. They modified his dorm to his accommodations, as they would for any other student with a disability.

Kirishima never thought of his problem as a disability. It's not like he has to wear hearing aids like Bakugo for his hearing loss or have to have special textbooks for dyslexia like Todoroki, He just couldn't pee. No matter how hard he tries, if he isn’t alone, in his room, with ample time to concentrate and relax every single one of his muscles one by one, His whole body would be locked up. Unable to pee no matter how badly he had to go.

When he was little, doctors said it was just a part of his quirk, his body couldn't handle it yet and was hardening in places that Kirishima was unaware of, like the inner wall of his bladder. He was told that as long as he still can pee, it's not a problem and he would grow out of it as he got the hang of his quirk.

Well, Years and years of only peeing in his home because that's where he was the most comfortable, so his quirk would be relaxed, had made a new condition arise even after he managed to gain control of his quirk. It's all mental now. He trained himself to pee in one place and nowhere else. That's what makes it so frustrating. He feels weak. That's why he hid it all through school.

When doing the tours of everyone's room the first week in the dorms, of course everyone, especially the girls, were upset he got a toilet and a sink in his room, while they had to use the communal toilets on their floors. He managed to brush it off as he was just lucky. When they moved to their second and third years and his new dorm rooms also had toilets in them, he used the same excuse, some bought it but others, his friends who he was close with, didn't. Bakugo, especially. Still, Kirishima kept his shy bladder to himself, coming up with some lame excuse about his legs hardening in his sleep sometimes so the teachers thought it would be best if he didn't have to walk as far to the restroom. He hated lies, as a future pro-hero, and to the person he looked up the most to, Bakugo. But his embarrassment over his biggest weakness overruled all of that, that was until today.

Kirishima cursed himself for sleeping through his alarm. He knew he had a morning patrol with Bakugo. Early morning patrol. But still the extra thirty minutes of sleep were too appealing to him. So when he was awoken by angry, fiery knocking at his apartment door at five in the morning. He had to get ready with the explosive blonde yelling at him to hurry up from the other side of the bathroom door. A very less than ideal situation to be in when you need to take your morning leak when you're in Kirishima.

He stared longingly at the safe haven that is the toilet in his apartment. Of course he had to take a morning piss, but with Bakugo here, it's impossible. He registered how badly he had to go, Have a full bladder is nothing he isn't familiar with, it's just something that comes along with having a shy bladder and being a hero, bathrooms aren't always available, He decided it's not even that bad, resigning to hold it for the rest of the five hour parol.

When your need is only a little annoying, five hours doesn't seem like too long of a wait. Of course, it doesn't seem fun, or ideal but manageable. But after two hours of constantly walking around the city, Drinking water to stay hydrated, Five hours seems impossibly long.

Kirishima paused for the fifth or sixth time in the last block to gather himself. He always walks behind Bakugo when they are on Patrol together so his stopping isn't noticed at first, but by now, he has lagged far behind his blonde partner without a proper excuse.

“Oi! Shitty hair! You're slow today! Hurry up.” Bakugo yells as he leans against a wall with his legs slightly twisted together. It's a weird game of wishing he could pee but also, trying so hard not to. In his pants. No. He doesn't want to pee, but for some reason his body feels like it might at any second. He knows from experience though, when he feels like he is about to burst and decides to give a public toilet or hell, even a tree a try, He locks up.

Luckily in his many years of dealing with this issue, a suitable toilet has never not become available to him before his body really couldn't hold it anymore. Before his bladder and an organ overruled his stupid brain and released against his will.

During his years at school, if he had to go, like, couldn't wait till classes were over for the day, He could wait to ask to go when he was in Aizawa's class and run back to the dorms really fast. Sure, Denki and Bakugo joked how he took so long he was probably taking a massive dump, but he took that over wetting himself in class. But now, six months into being a pro-hero. Six month after he has graduated and is working the dream with his best friend, Its seems he in a situation where the sanctity of his apartment bathroom isn't going to magically appear.

“Let's take our break. Its to fucking early nobody needs to be saved.” Bakugo huffs ahead of him, walking over to the side of a building and squatting down into a resting position. It takes Kirishima a bit to waddle over there and join Bakugo, opting to lean against the wall instead of squat.

“Here, maybe this will wake you up.” Kirishima swallows hard as he sees the bright red energy drink being hoisted from Bakugo’s backpack in his direction. Any more liquid entering his body sounds like torture. Especially since last night he drank not one but two lemonades at dinner before he went to bed and of course he did not use the bathroom before bed because it takes a while and he was just too tired.

“Thanks man!” He takes the drink, because how could he not? Bakugo even went out of his way to get him the limited edition red riot flavor. He cracks open the can and takes small sips while Bakugo eats a granola bar also from his backpack.

“I gotta take a leak, Keep watch for me.” Bakugo shoves his trash into his bag and stands up. Kirishima nods. This is normal. This is what Bakugo or Denki always do when they are on patrol. They pick a shy corner of the city and water the side of a unexpecting building multiple times during long patrols like today.

Kirihimas looks out into the silet road, the sun only having just rissen the city is still dead quiet. The only sound in his ears in Baukgo’s piss splattering hard against the concerte and its testing him. His limit was reached a long time ago. His body aches below his belt more than he can even remember. He looks back and see’s Bakugo isn't looking in his direction and takes a second to shove his hands between his legs and god, the instant pressure release on his muscles is orgamsic. He didn't even realize he had hardened his inner-thighs till the backs of his hands grazed them. He relishes in the fact that for now, he doesn't feel like he is about to pee his hero costume. If he could just stay like this for the remaining three hours, he could definitely wait to get back to his apartment.

“Okay, I'll keep watching now.” Kirishima is startled by Bakugo placing a hand on his shoulder.

“Ah-um what? I mean welcome back!” He doesn't know what to say, as he frantically turns around for his eyes to meet his hero partner.

“Your turn, so piss.” Bakugo orders him, but Kirishima doesn't move. In fact, he hasn't moved since Bakugo stopped peeing. In fact, his hands are still plastered between his legs.

“I don't have to go.” He says, Trying with all his might to move his hands away from his crotch but they just won't. His body is screaming that if he moves them, he will pee.

“Shitty Hair, You look like your about to piss youself, don't be weird just fuckin go. I know you like, ``Don't usually have to go on patrol but, don't worry, you won't get in trouble, it's like, fine.” Kirishima lets out a small sigh, At Least his friend thinks his weirdness is due to the fact he is hesitant about peeing outside and not because he is hesitant about peeing in general.

He is about to say something along the lines of how he just wants to wait until an actual bathroom is available when his hands no longer are enough to keep everything at bay. A small, miniscule amount of the liquid inside him shoots into his hands. Causing his eyes to widen. His costume is thin and water resistant. It absorbed absolutely nothing. His palms are wet.

“Did you just piss? Dude! Go, Hurry, jesus christ Idiot don't wait so long next time, You could have gone first…” Bakugo grumbles as Kirishima is pushed farther back into the alley by his warm had. Luckily, Kirishima's brain locked himself up when Bakugo started talking and the leak was nothing more than that.

Realizing he is in an inescapable situation he musters up the courage to at least try to be normal. Try to relieve himself. Hell, he just pissed in his pants, albeit a tiny bit, maybe his body will just have an accident, but outside of his pants and against a wall. He unzips his costumes, checking to see if the leak did in fact make any visible spot. It did but only on his inner thigh, not visible to anyone who wasn't looking for it.

He aims for the ground and goes through the motions in his head like he is at home. He tells his body he is safe. He makes sure his quirk isn't engaged. He relaxes his shoulders and his neck, then his core, Basically releasing all his muscles one by one, even wiggling out the tension in his toes. But nothing happened. He feels the familiar burning down there. The piss being pushes against the opening, but nothing coming out because his stupid body is yelling at him.

“Please. I need to go, please, it hurts.” He wills his body, but talking, worrying, pleading, only make it worse. The burning runs feather up into his body from the tip, stopping in his groin. The pain of trying to not go into his bathroom is more painful than trying to hold it. He quickly shoves his dick back into his pants. The pain is intense. He wants to curl into a ball. To hide. Now that he isn't in a place he can pee his body feels like its about to let go. He shoves his hands back between his legs and waddles back over to his friend at the front of the alley.

“Whoa? Kirishima? Are you okay?” Kirishima is startled by his name leaving his friend's mouth as he takes the last painful step to stand next to him. It's at that moment he feels the wetness. Not from his bladder, but from his eyes, cascading down his cheeks, beyond his controll.

“No. I-Its hurts.” He cries into the open air of the early morning. He wants to cover his eyes with his hands but he can't let go. His muscles are tired. His fists are hardened around his member with his quirk between his legs to hold everything in causing him more pain.

“What hurts, tell me? Are you sick? Do you need to go to the hospital?” Bakugo’s voice is calm. Kirishim recognizes it, it's the one he uses when they rescue people. When he talks to scared children or hurt citizens.

“No, I need- I need to go.” He hangs his head, looking down as his tears wet the ground below him in tiny droplets. “Go? Didn't you just go?” Kirishima doesn't look at him but can feel the confusion in his tone. Of course, Bakugo couldn't hear that he didn't go. His hearing is bad from his Quirks causing so much damage in High school.

“No. I-I couldn't go. I can't go.” Kirishima admits, not stepping from foot to foot, openly potty dancing in front of his best friends, his hero partner. His former classmate. The man he looks up to. Searing pain shoots through his entire body. He doesn't know if a bladder can literally explode from holding it for too long but if it can, he has passed that threshold. His hands are numb from holding, his dick is numb as well from the sheer pressure he is putting on it with all his strength.

“I-I don't understand, What's wrong? Why can't you go? Eijirou, you can tell me.” Kirishims looks up. Bakugo rarely uses his first name. His eyes widen as he feels another trickle of pee leave his tight grip. He doesn't grip harder to stop it but it stops on its own once he is aware of it. At this point the pain is so bad he wants to pee his pants. He just wants it to be over.

“I can't pee unless I'm at my house. I have a condition… Please! help me! I don't care how! It hurts, please, Bakugo.” Kirishima walks forward a few steps and practically falls against Bakugo. His forehead resting on his warm shoulder. His whole body is exhausted from the sheer need to release.

“Stop hurting yourself. How can you go if you're squeezing yourself so hard!” Kirishima feels Bakugo’s grip tighten on his wrists, pulling his hands away from his crotch.

“Ouch, Ah.” Kirishima cries harder into Bakugo, letting his hands spring up and wrap around the blonde in a tight embrace. His hands no longer helping, his lower half burns. His muscles feel like they are ripping apart trying to keep himself from peeing.

“Shhh, it's okay. I don't really understand what's going on, but it's okay. It's just piss. Just relax. I got you.” Bakugo’s voice is just a whisper in his ear and he cries into the embrace.

“It's not working. It hurts. I have to go so bad, I can't hold it anymore.” Kirishima cries. He’s never wanted to be normal more in his whole life then right now.

“Then don't hold it. You never need to hold it when you're with me. I'm here, you're safe. Just let go. You will feel so much better.” Kirishima lets his body melt into Bakugo’s words. He is safe. Bakugo tightens his arms around Kirishima as a slight patter of liquid hitting the ground echoes around them.

“Ah-no,no,no.” Kirishima feels a second of relief before he locks up again. He managed to pee. He managed to get some out, but it was only a little.

“There! You did it, just keep doing whatever you did.” Bakugo lets his hug go slightly,

“Tighter! Hold me tighter! Keep talking please, it hurts!” Kirishima pushes his mouth into Bakugo’s shoulder, his pointy teeth drawing into the skin from the pain. He feels Bakugo’s warm hands pull him in tighter, their stomachs clashing together. He feels warmth radiating from Bakugos whole body, like he himself is submerged in the warm bath of an onsen. Onsen? Wet? Water? Kirihimas realizes he feels the burning between his legs fizzling out into nothing, into numbness. Then he feels it. Wet liquid pooling down his legs and around his feets. It's hot. But not as hot as Bakugo’s hands rubbing his back in circular motions.

Kirishima lets out a strained moan, letting his whole body loose into the grasps of his best friend's arms and he shamelessly pees into his hero costume. He doesn't even care. All he can focus on is the feeling of his inside going numb from the subtle release from constant pain. His eyes fall shut loosely instead of scrunches painfully tight. He doesn't try to force his pee out faster, in fear it would have the opposite effect and lock up so he stays still, the only movement is bakugo rocking him back and forth a little as he rubs his back. After the longest most blissful minute of his life, he finally feels the warmth between his legs cool. The only indication he is done because he can't really feel anything but tingling between his legs from holding himself so hard with his quirk.

“Are you done? Do you feel better? Are you still in pain?” He feels Bakugo’s hands release him from the embrace a few seconds later. Kirishima stumbles backwards to lean against the wall of the building.

“Yes, And no, No pain. I feel weird though.” He looks down at his legs and sees the darkness in his crotch and the huge puddle beneath his and Bakugo’s legs. His eyes trail up and see the horrifying sight of wetness all the way down the front of Bakugp’s pants as well.

“Oh my god. I peed on you!” Kirishima jumps up from the wall and frantically looks around, not knowing what to do.

“Shitty hair! Calm down! It's just piss, like I said. I don't care as long as you are okay. You seem fine, so forget about it.” Bakugo grumbles, shifting a little where he stands. It's then Kirihmas realizes how uncomfortable his wet costumes feels.

“Let's walk back to my place and get cleaned up, I know you said it's fine, but i'll explain what happened on the walk there.” Kirishima wants to cry. To hide, to lie himself out of this like he always does. But Bakugo’s caring eyes on him as he cried in pain are the same eyes looking at him now and he can't lie to them anymore.

He explains everything from the dorms back in school to the doctors visits when he was a kid. Bakugo listens as they walk and expresses his concern for his friends when Kirishima tells him he always has to go really bad when they work. He explains why today was so much worse. Making sure Bakugo knows its not his fault.

“Thank you for telling me. Now I can at least try to help you with this, like I could have back at UA if you didn't try so hard to hide it.” Bakugo says as they reach Kirishima's apartment.

“Help me?” Kirishima asks, opening the door.

“You said you havent been able to take a fuckin piss outside of your damn house since middle school, well today, you pissed outside. I’d says that progress. Maybe next time, I can help you while your pants are down. And maybe, I can not be in the direct line of fire.” Bakugo laughs, motioning to his wet pants as he un-bottoms them in the entryway of the apartment.

“You would really help me? I think you um, holding me, your warmth helped, if that's too much, then it's okay, I can manage-” Kirishima’s ramblings are cut off by a swift kiss being placed in his lips. ‘ Bakugo’s lips are warmer than the rest of his body.’ he takes a mental note of as the lips part his.

“I’d do anything for you Eijirou, Don't you know this by now?” Kirihima blushes, Walking past Bakugo straight into the bathroom to shower. Even though Bakugo is waiting to also shower. Kirishima takes a few extra minutes under the hot water to calm down his racing heart. He might have embarrassed himself in front of his Former classmate, his Hero partner, His best friend, The man he has looked up to for so many years, but, that doesn't really matter because now that person, Is the man he loves and has loved for a long time.
