Sleeping alongside the fiery teen was something Kirishima cherished. It was the one time his explosive chihuahua of a boyfriend actually looked peaceful. Kirishima could sit and watch the rising and falling on Bakugo’s chest for hours. Knowing he could coo over the sleeping boy as loudly as he wanted because Bakguo took his hearing aids out to sleep.
“I love how soft and small your lips are.” Kirishima spewed his sleeping boyfriend with compliments that, if he could hear them, would get him shut out for days or explode into the next century.
“I wanna dress you up in the UA cheerleading uniform and-” Kirshima cringed at what he was about to say, deciding he actually is delirious and should get some sleep. He lays his body down into Bakugo’s. The blonde feeling his warmth instinctively wraps his arms and legs around him into a tight cuddle. It only takes Kirishima a few minutes to drift off to sleep from the comfort of being surrounded by his boyfriend.
***
Kirishima's eyes shot open to the feeling of discomfort in his lower abdomen. He couldn't really see much, besides the low glow of moonlight outside signalling it isn't morning. He looks at the clock, he has been asleep about four hours, His alarm isn't set to go off for another three. Even he thought he couldn't be that early of a riser, he adjusted his position, trying to find comfort but only found he couldn't move, and the comfort was not found, it was substantially worse. He needed to piss, and quite badly considering it had woken him up. But the problem is, Bakugo has his entire body draped over him.
Unable to move, Kirishima looked around Bakugo’s room. Nothing was really there to distract himself. The walls have some all-might posters and there was a small lava lamp on the blonde's desk but it was turned off. He tried to nestle into Bakugo, to try to go back to sleep, but his brain was sending him constant signals that that was not okay.
Feeling like he has no option, he taps on Bakugo’s shoulder with his one free hand. The blonde dosn’t stir even in the slightest.
“Bakubabe, get up, I need to take a piss.” Kirishima says, poking at him again, but he doesn't stir.
“Katsuki-Get u-” Kirishimas realises mid sentence, his words are falling on deaf ears…literally. He wasn't going to be able to wake Bakugo up with his voice. He shook his body to try to move the blonde off of him, but the movement just make Bakugo grip his hands together around the him.
“Fuck.” Kirishima cursed to himself, Bakugo’s legs pushing hard into his overfilled bladder. He usually didn't have to get up to pee in the middle of the night, so this had never been a problem before. Bakugo never instructed him how to wake him up when he was asleep. The blonde usually woke before him.
Kirishima was getting desperate. He had to go and he had to go now. He tried using the strength he had with just one free arm to forcibly remove his cuddlebug of a boyfriend from him, but Bakugo even in his sleep was much stronger than he was. If anything, he managed to get himself more stuck, Bakugo’s head now leaning in the crock of his shoulder. He couldn't even raise his free hands to reach Bakugo.
“Please.” Kirishima begged. Literally unable to move under the smothering cuddled. He felt the first drip escape him. He wanted to reach down and grab himself but Bakugo’s mid section was draped over him in such a way, even if his hand was free, he couldn't reach it. He feels the wetness seep into his pyjama pants. He cringes, he starts to panic. He cannot pee in Bakugo’s bed. He will have a fit.
“Get off! Get up! Please!! Katsuki you're so heavy!” He yells, but he knows it's doing nothing. He can feel his control slip, It starts out feeling like nothing, before he feels the trickle of wetness trail up his back from under him. His lap is also filled with pee as his muscles fail. “No! Stop!” He cried, but its pointless. He is peeing in his boyfriend's bed.
“Oh shit!” Suddenly, weight is lifted off of him in a second, he doesn't know how to react, he looks up from his sodden pyjama pants to see Bakugo on his feet with his hands shoved between his legs looking confused. Kirishima looks back at him, forcing the tears to not fall.
“Shit. I didnt think- I should have told you Kirishima, I sometimes, It just happens, I dont know how I managed to not even wake up or realize, I dont even feel like I have to go, my pants are wet and so are yours so, fuck, Im so fucking sorry, I guess I should have warned yo-” Kirishima looks up confused at Bakugo’s rambelings, realizing what is happing.
“Bakugo.” He shouts, But bakugo has his back turned away from him.
“If you tell anyone I sweat to go, It just fuckin happens, and im not ashamed of it, its just,-” Bakugo turners around,
Kirishim catches his eye still yelling his name, he points to his ears and Bakugo’s expression lights up and he grabs his hearing aids from the nightstand.
“Shit. I forgot I couldn't hear.” Bakugo shoves his hearing aids in and the first thing he hears is a quiet sniffling and silence cries coming from his bed.
“Hey, what's wrong?” He immediately goes to his boyfriend's side. He realises being pissed on isn't exactly the most romantic thing, but it happens to him all the time, and he never cried.
“It wasn't you, I-I peed myself. I couldn't get up!” Bakugo’s eyes go wide at the realisation.
“Why didn't you wake me up?” He questions, confused now more than anything.
“I tried! You couldn't hear me and It doesn't matter, I'm going to my room.” Kirima gets up from the bed, not looking at the dark spot on the blue sheet but he is stopped by a hand.
“Did you not hear what I said shittyhair? I'm the deaf one here. Calm down.” Kirishima turns to Bakugo already stripping the sheet off the bed, he sees a blue and white pad type thing under it, that Bakugo swiftly crumples up and throws into a small garbage bin under his desk.
“You aren't mad?” Kirishima turns to him, stopping trying to leave.
“I aint mad at myself when it happens, why would I be mad at you?” Bakug is already grabbing a pair of clean sheets and another absorbent pad from his wardrobe to make the bed.
“Well, because I was awake when it happened.” Kirishima cringes at the admission, also now more aware he is still still standing in clearly soiled pyjama pants, as is his boyfriend, but it's with his own pee.
“I am too sometimes, I'll wake up and before I can get out of bed, I'm already pissing. Same shit. Its a good thing we slept in my room tonight, your mattress would have been fucked.” Kirisma is confused as to how his raging, explosive, and no chill boyfriend is so calm about this, but he accepts it.
“There are dude wipes in the wardrobe, and sweatpants, if you don't wanna shower right now, I don't care, I'm just gonna use those and go back to bed.” Bakugo walks over to the hamper and strips down and chucks his clothes in it with the sheet, almost working like a well oiled machine. Next he pulls out a wipe and cleans his legs and crotch, he hands Kirishima a wipe and he sheepishly follows along the process, before long they are both back in bed snuggling.
“You're not upset, really?” Kirishima asks half asleep.
“No idiot. If you couldn't tell, I'm used to this. If anything, I feel better now that you know my secret” Bakugo says in his groggiest voice, reaching to take out his hearing aids again.
“Wait! Dont! You need to tell me how to wake you up, As much as you handled this like a champ and I'm not really embarrassed, I don't want this to happen again.” Kirishima sits up to look at Bakugo.
“Lick me.” Bakugo says with a straight face.
“Huh!?” Kirishima exclaims
“Water, liquid, It's the only thing that makes me wake up before my body is ready…hence why I guess my brain makes me pee in my sleep, It wants me to wake up for some god forsaken reason. Now go to sleep. We have class in two hours.”
Kirishima blinks away the shock from that answer. He is able to settle into Bakugo’s cuddles, mischievously knowing now that at least he can wake him up by simply giving him a wet willy.
