Work Text:
The problem with going on a school trip with Aizawa as your chaperone is he is a stickler for sticking to schedule. It's not often class 1-A gets to venture outside of the world of heroics and just have a fun weekend. Hell, getting to leave the dorms is a rare occurrence let alone leaving tokyo.
The class earned a trip away from UA for a weekend. Deciding as a whole to go to a private onsen located about six hours outside of tokyo. So thats how all of Aizawa’s class found themselves four hours into their journey regretting not opting for Midnight to chaperone their bus.
“Please. I don't know how much longer I can wait.” Izuku cringes as he grips himself tighter. His hand long since losing feeling from holding his crotch so hard.
“Shut the fuck up! You're making me have to go!” Bakugo shifts side to side in his seat beside the desperate green haired boy.
“Sir, If we could just take a brief stop…” Iida tries once more to reason with their teacher.
“Enough. I know it's annoying, but we have to be at the onsen before three. If we don't stick to the schedule we will be in trouble with the principal. Considering he didn't even want us to take this trip and considering how dangerous it is outside of UA…” Everyone on the bus hears the remorse in their beloved teacher's voice as he once again informs them a break is not possible.
“Hey, be grateful at least the girls aren't on board to see us like this.” Mineta pipes up from the back of the bus. Everyone stares daggers at him, ignoring him as much as possible.
Their teacher isn't an idiot. To think a bus full of kids could for six hours without relieving themselves is ridiculous. They had one planned stop half way, about an hour ago at this point. Mintea was already being very vocal about his need, enough for everyone else to keep quiet about needing to go. In turn, the purple haired bastard was the first one off the bus and the only one to make it into the restroom on their one stop.
The perverted asshole emptied his seemingly full bladder in second and used the rest of their brief break to sneak into the girls restroom that happened to be occupied by the girls bus that had stopped along with them. When Aizawa caught wind of Minetas' perverted ways he rushed off the bus before anyone had the chance, pulled him onto the bus, scolded him for over thirty minutes, leaving everyone watching in agony not wanting to be the one to stand up and interrupt. When he finished scolding Mineta he angrily told the bus driver to head out as they were not way behind schedule.
Now very few boys of class 1-A are left with an empty bladder, besides Mineta.
“Oh. I really didn't think this is how I would end up peeing my pants for the first time since elementary school.” Kaminari is the first to bring up the idea of any garments being soiled.
“Shut up, Pickachu! None of us are gonna do that shit. We just have to hold it!” Bakguou barks back at even the mention. He has to pee. Really bad. Worse than he ever has in his life, but he won't let anyone know. Not yet. He is stronger than that.
“Kaachan…I-I think i'm gonna wet myself. A little came out.” Midoriya admission is barely audible.
“Midoriya-kun, I have a bottle.” Todoroki says sitting directly behind the Bakugo and Midoriya. Bakugo’s body reacts to the mention of the bottle more then he would like. Midoriya gently lifts himself up from his chair and turns around to look at Todoroki. The icy-hot kid looks no better for wear than Midoriya himself. The hand not offering up the empty Pocari Sweat bottle is planted firmly between his legs.
“Todoroki-kun, I couldn't. You have to go as well and it's your bottle.” Izuku is panting with need between each forced sentence. He knows from past experience he has the smallest bladder out of most of the class, apart from Mineta. He always is asking to go during class and excusing himself from training the second it ends to run to the nearest bathroom. That being said, He is no stranger to wet pants. He would like to get off this bus without having an accident, but he knows he will survive if it happens. It happening in front of all his friends, is what he isn't too pleased about.
“I insist. You seem to have to go more than any of us.” Todoroki says to Midoriya. The squirmy green haired boy thinks to himself for a second, knowing how good it would feel to just let go.
“Please.” Midoriya’s thinking is cut to a halt as the familiar voice beside him lets out a pained plea. “I forgot to go before we got onto the bus.” Bakugo whispers, Everyone can hear him, the bus is silent besides the rustling of everyone squirms. Midoriya mouth settles into a frown. The one person he knows to have issues voicing his need as a kid looks up at him with tears in his eyes. His hand moved to his crotch at some point during his and Todoroki’s exchange.
“Kaachan, why didn't you say something sooner.” Midoriya asks, not trying to pull attention to the wet patch he can already see forming under his childhood best friend's hands. Luckily his pants are black so it's hard to notice unless you're sitting directly beside him.
“Embarrassing.” Bakugo squeezes out. Midorya can recall Bakugou as a kid saying the same thing when he scolded him for waiting too long to mention he needed to go and then ending up wetting himself on their way back to one of their houses to use the bathroom. Midoriya wastes no time turning back around to Todoroki. He doesn't want to remove one of his hands from his crotch to grab the bottle but he does so. Ignoring the wetness, he immediately forced its way into the palm of his other hand.
“Here, Kaachan, use this, come on, it's okay.” He moves the bottle down to Bakugou’s line of sight. His eyes focused on his crotch. Bakugo wastes no time relinquishing his grip from himself and pulling himself out. Piss wet his black pants every more as he was already forcefully peeing when he pressed his tip to the lid of the bottle.
“Ooooh, Deku! Don't go so loud I wasn't kidding when I said I was gonna piss myself!” Kaminari yells from a few seats back.
“It's not Midoriya-kun, it's Bakguo-kun.” Todoroki announces to the bus. Unbeknownst to Todoroki, his statement is untrue. As the gasps and moans coming from Bakugo right beside him are his ultimate undoing. He is just resting. Pee is slowly wetting the plush bus seat below him. Soaking up his slow accident.
“Bakubro?! Did you overflow? I hear dripping?” Kirishima looks back from the seat in front of Midoriya and Bakugou. Only to be met with a red faced Midoriya, hands no longer shoved between his legs as he gives into his need. Already half empty from slowly wetting himself, he lets it out. Pee immediately pools and drips onto the floor of the bus. Splattering and running backwards as they are driving uphill.
“Sorry. I couldn't hold it.” Midoriya announces, hoping some shoes at least gets saved as his accident loudly splashes onto the ground.
“Fuck! I need something. Please, a bottle? A towel?” Kaminari yells, he is half standing from his seat, seatbelts long forgotten at his point. Dancing with his hands between his legs.
“Here! My jacket! Take it.” Kirishima is up and out of his seat, stripping his jacket off of his arms and throwing it down into Kaminari’s seat.
“Dude. I can't! I can't piss in your jacket!” Kaminari yelps, sitting down makes him leak. His hands were not doing as much to hold back the flood as his potty dance was.
“If I hear anymore liquid splattering like that, Ill fuckin loose it too. You're doing me a favour.” Kirishima is red in the face. Kaminari swallows hard and removes his hands from his crotch, grabbing for the blue fabric of his friend's jacket. He thrusts it into his crotch. Letting go, pee erupts out of him. The hiss is loud for a few seconds before it's muffled by the wet fabric of the jacket. Kaminari is confronted by the warmth of his pee surrounding his dick. He relishes in the feeling before he realises he needs to readjust the fabric so more pee can be absorbed. He tightens his muscles for a second and moves the jacket forward, holding a dry part to himself and letting it go once more. His stream tapers off shortly after, not having to move the sopping wet garment around anymore.
“Oh my god. Thank you Kirishima!” Kaminari exclaims, letting his head fall back.
“Hnnnggg! No problem. Watching that was hard but I'm still dry!” Kirishima gives a thumbs up before walking back over to his seat in front of Bakugou.
The blonde is twisting the cap onto the bottle filled to the very brim with his pee.. His cheeks are red, his pats slightly wet but he is overall, doing okay. He manages to almost empty out his entire bladder in the bottle.
“Thanks Deku.” Bakugou mutters, shoving the bottle into his backpack at his feet, ignoring that it is wet with said green haired seatmates pee.
“Sorry.” Midoroya blushes at the squishy noise Bakugou's bag makes. He is uncomfortable, sure. His pants are cold and his legs are itchy but it's nothing he hasn't dealt with before. He just wishes he could have spared the bus driver having to clean up.
“Don't worry about it. You saved my ass, I won't tease you for this.” Bakuoug huffs, looking down at his lower half as he feels his bladder contract from being semi-empty.
“Um, I still have to go.” Kirishma says under his breath.
“I would say I'm at capacity as well.” Iida says from the seat next to Kirishima.
“Man, I feel great! It just kinda feels like I'm sitting on a wet towel after swimming in the ocean.” Kaminari pipes up from the back of the bus. Bakugou and Midoriya quickly realise what happened to him while they were preoccupied with their own accidents.
“Kaachan, do you have anything in your backpack?” Midoriya asks, Bakugou thinks for a second before pulling out two small hand towels.
“I used these to wipe the sweat off my hands so I dont blow my phone up by accident. They are clean.” Bakugo hands the two small handkerchiefs to Kirishima who looks concerned.
“This won't hold anything.” Kirishima looks about ready to cry and it pains Iida to his core more than his need to pee is at the moment. He is supposed to be the class rep. He can't let his classmates, his friends, suffer.
“Kirishima-kun! Take both of them. Relieve yourself as much as you can into both and try to prolong your holding abilities until we get there.” Iida says chopping the air with the one free hand that isn’t between his legs.
“Iida, I couldn't. You need to go as well…” Kirishima hesitates,
“The more of us who make it off of this bus with dry pants, the happier I will be as class rep.” Iida announces and Kirishma nods firmly. He can't disobey the manly order of his class rep.
He wastes no time pulling his dick out of his pants and shoving the tip into the dark coloured hand towel in his hand. He feels the first dribble escape his tough muscles and he wants to close his eyes and let go, but resists. He watches closely as he lets out small spurts of pee, controlled, until the towel is soaked through. He squeezes harder and clamps down and accesses his need. He still had to go very badly, but figures he better try to keep his pants dry like Iida says. He holds the remaining towel up and places it under himself inside of his underwear. Iida watched him do so.
“See now If I leak before we get there, It will be caught by the towel. I could still get off of here with dry pants. Thank you Iida!” Kirihmas doesn't feel relieved but he does feel secure knowing any laps in his ability to hold will be caught by the towel.
“Can yall shut up? You made it smell horrible in here and I have to pee again! Aizawa-sensei! Can you pull over!?” Mintea screams from the very back of the bus. Everyone's eyes on the bus dart back to the grape haired bastard. Bakugo and Kaminari make eye contact and both get up from their seats.
“Oh yeah you have to pee again?!” Kaminari asks, sitting on one side of him.
“That much fuckin suck.” Bakguou says, sliding his arm into a headlock over Mineta’s shoulder. Making it so he cant get up from between both blonds.
“See you guys get it. Make Aizawa stop okay? I'm sure with your bladders being obviously so embarrassingly small you both couldn't hold it have to go again as well.” Kaminari and Bakgous share another look, both with equal deviance.
“Pshhhh.” Kaminari starts making waterfall noises with his mouth. Bakugo tightens his grip on Mineta and brings a hand up under his armpit and starts to wiggle his fingers.
“Think of waterfalls! Think of how good it will feel to pee. Shhhhhhhhhhh.” Kaminari teases as Mineta laughs with tears in his eyes.
“I have to pee! Let me go! Sensei, they are torturing me!” Meneta cries out.
“Good. you deserve it.” Aizawa groans, half asleep at the front of the bus. Bakugou and Kaminari seem to take this as their sign to go harder as Kaminiris waterfall noises get louder and louder and Bakugos tickling gets more intense.
“I'm peeing! Stop! Let me go!” Bakugo pauses his ticking and springs up off the seat when he sees the seat of Mineta’s pants darken. Kaminari cease his teasing noises and lets the bus fill with the sound of Mineta pittyfull wetting himself. The sound only lasts for a few seconds.
“Bastad didn't even have to go that bad! That's no fun!” Bakguous huffs,going to stand back up and go to his seat when a loud, distant hissing catches his ear. His eyes flicker back to Mineta but he is just crying into his hands. Bakugo looks to the front of the bus to see Iida standing in the isle with his hands hovering above his crotch.
“The waterfall noises got to me.” Iisa says as the dark colour of his uniform pants grows darker as pee splashes down the isle of the bus.
“Iida please sit down, it's dangerous.” Aziawa picks his head up from resting on the window in the first seat, Iida doesnt look up from his steady stream leaving his pants.
“Sir, I am having an accident, I will sit once I'm finished. The seats don't need to be unnecessarily dirty.” Iita says sternly.
“Almost every seat, including mine, is ruined. Just sit. It will be more trouble if you hurt yourself.” Aizawa says softly. Iida looks up, or more over, looks down at Aizawa to see the remnants of a past accident already drying on his hero uniform.
“Sensei?” Iida asks in shock,
“I said no stops, not even for myself kid. It's for your safety. Pants can be washed, everyone! Now, seatbelts on we are almost there!” Aizawa finished his sentence by yelling, everyone hastily, buckled their belts.
“Pst, Kaachan, I have to go again…” Midoriya whispers into Bakugou's ear. Bakugo looks at him with mild concern, but decides now isn't the time to lecture his childhood friend on his bladder health, nor is he the person to do so.
“Just go, Deku. It's dumb to hold it, trust me.”
“Yes, Midoriya-kun. I've already gone twice. I didn't want to make myself sick for our trip.” Todoroki nonchlauntly says over the back of the seat. Bakugou's quirks and eyebrows look at the floor under Todoroki’s seat and is dry, and his pants are as well. Bakugou's eyes go wide in realisation. icy hot is wearing a diaper.
“Ahhhh.” Clearly the realisation doesn't hit Midoriya because Bakguous hears the relieved sigh and a few seconds later followed by a gentle pattering of liquid onto the floor. Bakugous stifles his laugh.
“What! I don't wanna get sick either!” Midoriya puffs out his cheeks and crosses his arms over his chest,
~~~~~~
They make it to the Onsen and Kirishima rushes to the bathroom in the lobby. Being the only one to make it off the bus with semi-dry pants. (the second towel didn't hold all his leaks) he offered to handle check in while everyone else beelined it to the showers and the bath. Mineta however, was instantly put back on the bus home without having the chance to shower.
After everyone is clean Bakugou pulls Todoroki aside on their way to the dining hall for dinner.
“Oi, Icyhot…” He makes sure nobody is in the vicinity to hear his embarrassing questions. “On the way home, Can I borrow one of your diapers?” Bakguou blushes when he asks, but he would like to keep his track record of not wetting himself.
“No.” Todoroki says sternly, Bakugo stiffens at the response, only to see Todorokis smile soften a second later. “You can't borrow it because I don't want it back, that's gross, but you can have one, sure.” Todoroki smiles, leaving Bakugo mouth gaping in the hallways.
“If you tell anybody I swear to god!” Bakughufss follows Todoroki who just giggles to himself at the blush on Bakugos face.
