Work Text:
The person who invented overnight stakeouts was a fucking idiot. Who wanted to wait around in the dead of night, freezing their balls off as they waited for some criminal scum to do what they do best? But unfortunately for pro hero’s like himself, it was a huge part of the job. Because apparently, storming into the building and blowing up the place wasn’t going to fly now that he wasn’t some angsty sixteen year old.
No, now he was expected to follow the law and gather evidence before he beat the criminals up, or at least that’s what Deku kept telling him. Even now as they were sitting up on the roof across from the warehouse the other man was blathering on about something or other. As usual, he wasn’t listening. If it was really important Izuku knew how to make sure he was paying attention. So for now he was content to just sit here and let his mind drift as he waited for something to happen.
Of course, that wasn’t the only thing that was on his mind at the moment. Something had been bothering him for the past half an hour or so. A twinge from deep down below his stomach, making him want to squirm and clutch at his crotch. He had to pee.
Now usually, he would just get up and go. He didn’t have a piss kink, no matter how much Kirishima insisted he did after once catching him staring at Izuku squirming at his desk back at UA. The idiot was known to have had a few close calls when it came to accidents back then, a fact that Bakugou had teased him mercilessly for. The little green-haired nerd had always been so enthralled in whatever class he’d been in that he refused to leave, even for a bathroom break. So, by the end of class he was usually a squirming mess and ended up dashing out at the bell to ensure that he made it in time.
But even then, the fact that the other man had to piss wasn’t what interested him though. It was the way that he was so clearly embarrassed from his situation that made him want to tease the other boy. He loved putting his long-time rival in humiliating positions. Seeing his face light up a brilliant red or seeing little tears form in his eyes made his whole day.
So yeah, he wasn’t interested in piss, and especially not in wetting himself. He was far too proud to let anything like that happen. So usually he would have just gotten up at this point. The only thing that prevented him though was that they had gotten a hot tip that the gang they had been tracking for the last month was supposed to show up at this warehouse for an exchange with their supplier. This was the best lead they’d had so far, even though they weren’t sure what time exactly they were supposed to show up. He and Deku had set up for the night, ready and waiting to spring to action as soon as they arrived and made the deal.
For a while, things had been fine. They’d talked for a bit about not much in particular, and broke down the evidence in the case which they would hand over to the police once they brought the gang in. However, as the night drew on and there was still no sign of activity he’d grown tired and began to drink the quite frankly ludicrous amounts of coffee Deku had brought along for the stakeout.
That had worked, for a while anyway, but had led to this particular situation. Because they were up on the roof it wasn’t like he could easily go to the bathroom. He’d have to go back downstairs to the main lobby of the building if he wanted to go, and in that time the gang could come in and shitty Deku would take all the glory. That was not going to happen, not on his watch! Besides, he was a big boy. Surely he could hold it for just the little bit longer until they got here.
That’s what he kept telling himself as the minutes dragged on into an hour and his need grew even stronger. By now he had crossed his legs and was bouncing a foot up and down impatiently. God, what was taking so long?! Were they even coming?!
He looked over at Deku, who at this point had realized that Bakugou wasn’t listening and had pulled out a book to pass the time. Well, at least he wasn’t paying attention or he might have figured out what was really on his mind. At this point his mind had started to wander. Izuku wasn’t even paying attention to him. He could probably walk over to the far side of the roof, whip it out and be done with it.
As soon as the thought crossed his mind though he blushed and pushed it from his mind. Yeah right! With as quiet as the area was Izuku was bound to hear him, and though the other man wasn’t likely to say anything he knew that nerd would be internally laughing at him at how he couldn’t hold it like a baby. Besides, he was Bakugou Katsuki, the pro hero Ground Zero! Surely he could hold his piss for just a little bit longer.
And hold it he did, until he was practically at the point of bursting. All that he could think about was his growing need to just let go. He had to pee so badly that it was practically hurting to hang on, and it must have shown as shitty Deku had been giving him odd looks for the last few minutes. Despite his best efforts a blush had started to creep up his face and his hands where balled up over his crotch, pressing down tightly to prevent any leaks.
The other hero spoke up for the first time in hours, asking “Kacchan? Are you okay?”
His blush instantly deepened at his words and he bit out. “Fuck off! I’m fine!”
Izuku raised an eyebrow, obviously putting two and two together based on his blush and where his hands currently were. The guy wasn’t stupid after all. “Geez, no need to bite my head off. If you have to use the bathroom, just go. I can keep watch in the meantime.”
He grit his teeth, his face now crimson with the realization that Deku knew exactly what was going on. “Sh-shut up! You don’t know what you’re talking about! Besides, I’m sure that you’d love me to leave so that you can take all the credit for the arrest! That’s the only way a shit-head like you could become a number one hero, by taking credit for other people’s work!” Okay, that had been a bit of a low blow. He’d mellowed out towards his childhood friend in the years since graduating UA, and they often collaborated on tough cases like this one. He knew that Izuku was a good hero, but he also knew that when he was feeling embarrassed or vulnerable like he was right now stupid shit had a tendency of spewing out.
Of course Izuku, the kind guy that he was, didn’t let his hateful words deter him, much like when they were kids. No, he kept on being the stupidly kind idiot he’d always been. “Come on Kacchan. It’s alright. I won’t make a move until you come back okay? Trust me, I’ve had a few close calls when it comes to making it to the bathroom, and if you don’t move soon you’re not going to make it.”
Oooo, as much as he wanted to stay here and shout obscenities at him, he knew that he was likely right. Even as Deku had been talking the first little leak had dampened his underpants, and he knew if he sat here like an idiot he would soon be sitting in a puddle. He still couldn’t help but mutter out a few curses as he made to get up though, just so that Deku knew that he wasn’t happy.
Once he was standing though he realized that perhaps he had waited a bit too long. Another spirt leaked out, just a bit longer this time. The blush on Deku’s face let him know that the other hero had heard it, which made him freeze up in humiliation. Oh god, he wasn’t actually going to piss his pants right in front of his rival, was he? God, he would never live it down if he did! Deku was sure to tell everyone; he’d be the laughing stock of the hero community! Forget being number one, he’d be lucky if anyone took him seriously again!
His hands once again flew to his crotch, squeezing to prevent anymore leaks. His legs didn’t seem to be getting the message that it was time to move though, so he was left standing there awkwardly in front of a blushing Izuku. Oh god, of all the times to freeze up, why did it have to be now! Why had his regular bravado failed him in just this moment!
His legs started to shake from the exertion of holding the flood of pee back, and too his horror he could feel his eyes start to prickle with tears. Oh fuck no! He was not going to fucking cry and piss himself in front of Deku! Please, god, no!
Despite his pleading however his body started to betray him. Another loud hiss rang out in the still night air as his underwear got so damp he could feel it though his tight grip. He was sure that if he was able to pull his hands away a wet patch would likely be visible.
Deku chose this moment to speak, reaching a hand out and saying “Kaachan, come on, you can still make it…”
The other man didn’t get any further than that though as finally Bakugou’s poor, abused bladder could take no more. It started as a trickle but soon grew steadier. With a gasp he let go, knowing that there was no holding back anymore. The pee gushed out of him, leaving long, wet trails down his pants. It trickled down his shoes too, making an ever-expanding yellow puddle on the rooftop.
Bakugou gasped as his legs finally gave out from the stress and he sank down it his knees as he continued to pee. Hours worth of urine just kept coming out with him unable to stop the flow. It felt like hours until he finally emptied himself out. His pants were absolutely soaked and there was no mistaking the putrid stench of piss around him.
Worst of all though were the tears that he couldn’t stop from running down his face, and the loud sobs that he couldn’t hold back. Of god, he’d really done it. He’d pissed himself like a toddler! And right in front of Deku of all people! No one else in the world had more reason than the other man to want to see him humiliated, and though they had both made great strides in getting along he knew that there was no way Izuku wouldn’t use this against him. If the positions had been reversed, he knew that he would have never let the other man forget it.
As he sat in the puddle of his rapidly cooling piss, he was sure that his life was over. Luckily though, he was wrong.
Instead of mocking him as he’d feared, Izuku set a hand lightly on his head and started to gently run his fingers though his hair. He couldn’t stop his sobs, but he did finally look up from his pee-soaked lap to shoot the other man a look of confusion. He was met with a soft-smile from the green-haired hero.
“There, there Kacchan, it’s alright. Accidents happen. You’re gonna be just fine.”
Though he knew he should have felt relieved that he wasn’t being mocked, the soft words just made him want to cry harder. Why was he being so nice?
“Why don’t we pack it up for the night huh? It doesn’t look like they’re going to show up, and I don’t think you’re in any mood to keep going are you?”
He numbly shook his head, still too humiliated to respond. But, he couldn’t help but lean into Izuku’s soft touch. The hand on his head felt…good. It gave him something to focus on aside from the sticky, wet feeling on his legs. For a few minutes it was just silent, him kneeling on the ground in a puddle of his own piss and Izuku reaching over and soothing him with a hand in his hair.
Finally, he was able to choke out “…Why…why are you not laughing?”
Izuku’s smile became even kinder as he leaned over so that he could press a kiss to his forehead. “What’s there to laugh at? You just had a little accident, that’s all. If you’re feeling up to it, why don’t we head out and get you all cleaned up hmm? I doubt that we’ll be seeing anyone tonight, they’ve probably rescheduled the meet-up. And even if they did show up, I doubt that you’d want to confront them in soggy drawers huh?”
His blush deepened as he heard Deku describe his predicament has having ‘soggy drawers’. God, that made him feel even more like a baby. But, it wasn’t like he was in much of a position to refuse his help. Deku could literally ruin his career if he decided to pull out his phone and snap a few pictures, so he figured that his best bet right now was to stay silent and hope that they could put this humiliating event behind them.
So, he merely nodded his head and allowed Deku to help him up onto his shaky legs. He couldn’t help but let out another sob as a bit of pee from his soaked underwear dripped down his leg. Izuku rubbed his back, whispering a litany of comforting words as they made their way down to his car parked down below. He stood off to the side as the other man laid out a few training towels on the seat so that he didn’t stain it and then quietly sat down.
He didn’t say a word the whole drive even as Izuku tried to reassure him that everything was alright. How could everything be alright? Deku was sure to never see him as anything more than a pants-pissing baby ever again. Even if he didn’t tell anyone else, Izuku had still witnessed his shame and surely wouldn’t see him as a rival anymore.
As they pulled into a driveway though he was a bit surprised to see that they had arrived at Izuku’s house instead of his own. What were they doing here?
This confusion must have shown on his face as the other man answered the unasked question. “My place was closer and I figured that you’d want a hot shower sooner rather than later.”
He nodded, blushing for what felt like the hundredth time that night. Normally he’d be blustering and complaining, but it was hard to do that when you were sitting in your half rival, half friend’s car in the early hours of the morning in piss-soaked pants. So without a word he exited the car, grateful that none of Deku’s neighbours seemed to be up to witness his shame.
Izuku quickly unlocked his door and gestured him inside, which he was all too grateful to do. Luckily he was no longer dripping at this point. He was just wet and embarrassed and wanted to get this whole thing over with. He wasn’t quite sure what to do with himself though, so he just busied himself with taking off his shoes.
Izuku took pity on him though, taking him by the arm and leading him down the hallway to the bathroom. “Okay Kacchan, strip down and clean yourself up okay? I think you might have left a t-shirt and sweatpants here from when we last had a training session, so I’ll grab them for you to change into.”
He nodded, waiting until he was left alone to start doing what he had been told. He winced as his pants made a squelching sound as he peeled them off, and he left them and the rest of his costume in a pile on the floor as he stepped into the shower. He scrubbed hard, wanting to get the gross feeling off of him, hoping that he could wash the memories away just as easily.
That proved to be a fantasy though as he was unable to stop the whole embarrassing incident from repeating over and over in his head as he scrubbed. He stayed in the shower long past what it took him to get clean, not wanting to have to go out and face Izuku once more. Still, once the water started to grow cold he reluctantly shut it off and got out.
Just as the other man had said, a pile of his training clothes was laid out on the toilet, along with a pair of what he assumed was Izuku’s underwear and socks. He toweled himself off and put them on, then left the bathroom.
He saw Izuku sitting down on the couch, having changed from his hero’s costume into comfortable clothes as well. He sat down on the opposite end and looked to what he was watching only to have his heart sink even more. “Uravity and Froppy have caught the Malcore gang!” shouted the news anchor excitedly as the program switched over to footage of their former classmates escorting the gang members into the back of a police van. After all that, and someone else had made the arrest! God, that was just the cherry on top of the crap ice cream sundae that he was having.
“Well, it’s good to see that the gang is off the streets at least,” Izuku said. While he was sure the comment was made to lighten the mood, Bakugou couldn’t help but feel mocked. It felt to him as though Izuku was saying, ‘while you were pissing your pants someone else was off doing the real hero work’. And god, it was true wasn’t it? The gang hadn’t even shown up, so he’d had this embarrassing accident for nothing!
He frowned, turning his head away as he felt those traitorous tears make a reappearance. Izuku’s face fell and he reached out to gently grip his shoulder. “Hey, hey. It’s okay Kacchan. No one saw but me, and you know I’d never say anything.”
The other man’s words didn’t make him feel any better though, and pulled back from Izuku’s hold as he felt his shoulder’s start to shake once more. “It’s not okay!” he choked out between tears. “I wet my pants like a baby! You probably think I’m disgusting and don’t want to work with me anymore!”
Oh. Where had that come from? Had he been worried that Deku wouldn’t want to team up anymore after his embarrassing display? He hadn’t given it much thought, but he supposed that since he had said it his subconscious must have been fearing it.
Izuku’s face crumbled and he scooted over so that he could wrap his arms around his childhood friend. “Oh Kacchan, no. I don’t think you’re disgusting! That’s the farthest thing from my mind! It would be pretty hypocritical for me to tease you or think poorly of you considering how close I came to having an accident back in school. And besides, you’re my friend. And it will take a lot more than this to make me turn my back on you.”
He sniffled, but couldn’t help but feel a bit of hope at his words. Maybe…he was telling the truth? He really didn’t think badly of him for his accident? “You…you promise?” he asked, cursing after the fact at the childish tone the question had. God, he really was acting like a baby tonight.
“Promise,” Izuku said, once more leaning over and giving him a little kiss on the forehead.
Bakugou’s eyebrows crinkled. That was the second kiss tonight! What was Izuku doing? He didn’t think before he blurted out “What’s with the kisses and being so nice! You could have laughed you know. I would have laughed if it had been you who had the accident! And you more than anyone have the right to be happy at me being humiliated like this.”
This time Izuku was the one to blush. He gave Bakugou a little squeeze before whispering. “Because you looked so cute.”
“What?” he couldn’t help but blurt out.
Izuku’s blush deepened. “You looked so cute. It reminded me of back in kindergarten. Remember? You had come over to my house and we were playing out back in the forest. We lost track of time and you were squirming around, hands between your legs just like you did today. You ran so fast all the way back, desperately trying to make it to the potty, but you didn’t make it and ended up peeing your pants.
You cried so hard and begged me not to tell anyone, and I promised you that I wouldn’t. Even though you were mean to me sometimes, in that moment you looked so cute and earnest that I couldn’t refuse you. I remember I took your hand and walked you back home so that your mom could get you all cleaned up. You were crying so hard, but I kept telling you that it was okay and that we were still friends. When you had your accident tonight it reminded me of back then, and I felt once again like I had to take care of you.”
Bakugou’s blush returned once more. He’d forgotten about that. He’d likely pushed the memory from his mind to prevent further embarrassment, but as he heard Izuku describe that day it all came rushing back to him. He was so sure that the other boy wouldn’t want to be friends with him after he’d peed his pants like that. After all, 6 year old’s weren’t supposed to have potty accidents. He’d made the other boy promise over and over that he wouldn’t tell anyone, and he hadn’t. Even when Bakugou and went from being his friend to his bully, he’d never told anyone, even though it would have been completely humiliating for him.
God, he didn’t deserve that level of loyalty.
And he certainly didn’t deserve Izuku’s help and comfort tonight. Not after all the pain he had put the other boy through, or the fact that he knew he would not have been so kind if their positions were reversed.
God, over the years he had felt a bit guilty over the past, but never so bad as he did tonight. He deserved to be ridiculed and hated, not cleaned up and comforted. These feelings were all welling up inside of him, and he didn’t know what to do. He felt so lost, with the only thing tying him back to reality the warm weight of Izuku’s arms around him. Guided by blind instinct he buried his face in the crook of his neck, seeking out the comfort he knew he didn’t deserve.
“I…I’m sorry,” he said in a small, meek voice. Anyone who heard it would barely be able to recognize it as Katsuki Bakugou, the loud-mouth hero. But he supposed that he wasn’t that right now. He was Kacchan. Izuku was the only one that still called him that after all; the only person he would let call him that. And maybe…for right now he could just be little Kacchan, seeking comfort after an embarrassing accident.
Izuku, for his part, took this all in stride. He rubbed Kacchan’s back and whispered soothing nothings to him, letting him know that everything was alright. The other man had all but crawled into his lap at this point, but thanks to his quirk he barely felt it. They stayed like that for a while until the late hour and the exhaustion from the last night’s ordeals caught up to the blond hero and he started to nod off from his place wedged against his friend’s neck.
Without saying a word Izuku utilized his quirk once more and lifted him up off the couch. To his credit, Kacchan didn’t even lift his head up, instead adjusting his weight a bit so that he was in a comfortable position and let Izuku take him wherever he wanted him to go. They ended up going to Izuku’s bedroom where Kacchan found himself being laid out on the bed and tucked in under the covers.
He snuggled down in, sleepy and content, until he saw Izuku start to move away. “Wait!” he said, reaching out and taking hold of the other man’s arm. “Stay?” he asked quietly, before tacking on a “please?”
Izuku smiled warmly, climbing into the bed without saying a word. Though he would likely deny any of this happening in the morning, for now Kacchan was past caring about his pride. He just wanted to feel the safeness and comfort that only Izuku could provide. So he snuggled in against his chest once more, quickly drifting off to sleep.
Izuku stayed awake though, content to rub a hand along his back and taking in the sight of the usually tough and harsh other man. Though, he supposed he wasn’t really the strong and capable Bakugou was he? No, he was little Kacchan, and for right now, he would do his best to protect him, just as he did all those years ago.
And as Izuku eventually drifted off to sleep just as the sun began to come up, he knew that his and Bakugou’s relationship had changed, and he was sure it was for the better.
