The summer heat in Japan is truly not something one should mess with. The high humidity mixed with the over 37 celsius temperatures can give someone heatstroke easily. That is why staying hydrated is so important…As Ida has reminded Katsuki every twenty minutes for the past three hours.
Class 1-A decided to skip out on the fancy indoor pool the UA has to offer, wanting to have a day off from training and actually enjoy themselves considering it's summer vacation. They opted to go to the neighborhood pool in Tsu’s part of town. Each of them had to pay a 500 yen fee to get in the door and rent a locker. Katsuki was against the whole idea at first, but Shittyhair and Pickachu managed to convince him under the pretense they would race and he had to show them he could kick their asses at anything, even without using his quirk.
So here he was, at the pool. Although not much racing has been had because after getting here, the girls commandeered the pool, wanting to float on little rafts, kicking the boys out of the pool because their splashing and overall rough housing makes the water too choppy for them to relax. Kirishima has the idea to get everyone slushy from the concession stand.
Katsuki happily accepted a cola flavored one and downed it in no time. The umbrella he is sharing with Ida is nice, but he is still sweating buckets. A pon watching him down the sugary beverage, Ida offered him a bottle of water from the cooler he brought with, saying something about how he is incharge of his class even outside of school and he can't have anyone getting dehydrated. Katsuki accepted and when he finished that bottle, another was handed to him. Before he even realized it he had dowed nearly four whole water bottles, and another was being pushed on him.
Katsuki could feel a small need building. He has already needed to go before getting to the pool.He figured he would just go when he changed, but him and Kirishima shared a locker and he was eagerly pushing him to change and get out to the pool to race, so he ignored it….Honestly he figured he would just piss in the pool while racing. It's not like he is foreign to the concept. He always pees in the pool at UA, figures they can afford the extra chlorine.
“I bought french fries and Nachos! Does anyone want some?” Sero walked over from the food stand over where the slushies were, carrying a large plate of nachos topped with bacon and jalapenos, Katsuki’s mouth was already salivating at the delicious spicy morales. He nods to Sero and the boy takes a seat on his lounger. Katsuki wastes no time digging in, taking huge bites of tortilla chips and cheese.
After a few bites, Katsuki finds himself reaching for his water bottle once again. The jalapenos they use at this place are extra hot and his tongue is tingling. Sero is also guzzling some sort of colorful beverage he bought at the stand. Katsuki groans as he finishes his fifth water bottle, feeling absolutely filled to the brim with Nachos and water, but mostly water. He looks over behind himself at the bathroom and decides he is desperate enough to warrant slipping on his flip flop and taking a piss.
He walks back over to the locker room, in search of the toilets. When he changed earlier he only saw the changing rooms and the lockers so he doesn't exactly know where to go. He rounds a corner, tucked back behind the family locker room to see the bathroom doors. Seeing the little blue sign with a man on it always makes him have to go more. He hurries over, cringing at the water he steps in as he walks, clearly people don't dry off before walking around.
Katsuki goes to grab the handle, eager now to expel all the liquid inside him when it doesn't budge. He tries it a few more times before getting angry and stepping back, that's when he sees it. A coin slot located right below the handle with a worn out sign saying ‘entering is 100 yen’
Katsuki groans. He really needs to go now. He looks around before giving himself a quick squeeze, his light orange speedo not giving much of a barrier. It feels good and gives him enough mental relief from his predicament to form a plan. He needs to get his wallet from his locker. Deciding that he begrudgingly walks away from the toilet and heads to the locker room.
He finds his locker rather quickly and precisely runs up to it, nobody is there to witness his restlessness, thank god. He goes to yank it open when he realizes he doesn't have the key. Him and Kirishima shared a locker because with the entry fee and towel rental fee, they both were running low on cash, Katski particulate was since he used his summer allowance a week prior on new gym shoes and gym shorts. He curses himself now for spending so recklessly. He gives himself another subtle squeeze, this time, it's harder to let go because he has to go so much more than before. Just knowing he can't get immediate relief has made him go from a five to a seven rather quickly.
He exits the locker room, beelining over the towels, eye scanning their group for the red haired friend but not having any luck.
“Oi, glasses, where is Kirishima?” Katsuki turns to Ida who is handing a water bottle to Koda.
“While you were gone, Sero got another thing of Nachos, but he spilled the hot cheese on his lap and it gave him a burn so Kirishima took him to the nurses station.” Ida says firmly, Katsuki sighs, He looks around and doesn't even see the nurses station, Not really wanting to look for it, his eyes turn to the pool, The girls are all floating on one end of the pool, away from the stairs…If he just waded in the shallow end and didn't make a commotion he could easily piss and cool off. He makes up his mind and starts to head to the water.
“Bakugo, Wait.” His shoulder is grabbed and it takes everything in him not to cross his legs as he turns around, Ida is giving him a stern look.
“What?!” Katsuki hisses, he just wants to piss, god damnit.
“You just ate. You have to wait thirty-minutes before swimming.” Ida says with no waver in his tone.
“Your kidding? Thats-Thats just a myth!” Katsuki laughs at him, but Ida doesn't let go of his shoulder.
“Stomach cramps and drowning are no joke, come sit, I'll keep you company. Don't worry the pool will still be there once you have had time to digest.” Katsuki follows him back to the lounge, taking a seat atop his towel again. He wanted to scream at Ida and tell him he has to pee so bad he feels like he is going to explode, but even he is against being that open about peeing outside of a toilet.
Katsuki sits and settles on tapping his foot, looking around hoping Kirishima will show up before things get worse. He feels a constant throbbing pain in his bladder already, so he doesn't really know what could be worse but he doesn't want to find out.
“Here.” Ida taps his shoulder, Katski grunts and looks in his direction, not really wanting to talk to him, considering how annoying he is being. He looks down at Ida’s hand offering him another bottle of water. “You haven't had enough to drink, you look uncomfortable, you might be dehydrated.” Katsuki rolls his eyes. He isn't dehydrated in the slightest, if anything, He needs to be less hydrated. He grabs the bottle with his hand and his body decides right then, it needs to get rid of some of its hydration because a small squirt of pee leaves Katsuki’s body. He drops the bottle in his lap and quickly presses his legs together.
“Oops, sorry it's really cold, I had Todoroki come and freeze the cooler again while you were gone.” Katsuki gives Ida no response and just hopes he leaves him alone. Soon enough he turns his attention to offering all of the girls waters as well, and Katsuki takes this time to inspect the damage.
There is a wet spot on the bulge of his speedo. The thing shows wetness a lot and is so thin, it holds nothing. That small leak is so visible and his body is screaming at him to let it happen again. He can't. He has twenty more minutes until he can get into the pool. He shimmies his towel out from under himself and places it over his legs, sliding a hand under and grabbing his cock for dear life, he just hopes this will be enough to get him through.
Ten minutes later and it's not enough. The palms of his hands are slipping as he tries to get a good grip thought his now soaked speedo. He leaked badly a few seconds ago. Ida came back and made him take a sip of the water, since it was obviously left unopened. When he removed his hands and the cold water made contact with his lips, he was done for. He only managed to cut off the stream when he closed the water and shoved his hands back under himself, Luckily it stopped, but not without pain.
“Hgggnnng” Katsuki groaned under his breath. The heat of all the piss trapped just at the tip of his cock is screaming at him. His body feels tingly from the sensation of letting go he just experienced. The lounge he is sitting in is one of those ones with fabric slats all across it, the kind that sinks down when you sit in it. He can see the ground below him is dry. He never did get a chance to get in the pool yet so any liquid under his chair would be obvious, thankfully, his towel caught most of the damage.
“Are you okay?” Katsuki looks up at the voice seemingly pointed at him, Its icy hot, standing with a bottle of suncream in his hands.
“I-” Katsuki doesn't know what to say. He gets his with another sudden wave of desperation and squeezes his hands tighter into his lap. “No.” He grunts out, feeling like he might lose it any second.
“You know…they have restrooms here.” Todorki says in his monotone voice. The tone usually doesn't bother Katsuki, rather he finds it calming but right now, the fact that he can be so calm while Katsuki feels another leak threaten to spill out of him makes him mad.
“Costs money.” He manages the words, they come out like a whisper.
“It's only 100 yen…It looks like it would be worth the investment.” Katsku can't believe his ears, was that Icyhots attempt at a joke? He shakes his head, he can't make fun of him now, he is too focused on not pissing in his pool chair.
“No-ahnnnnnggg wallet.” At this point, the pain from just squeezing himself so hard to keep in what his overworked bladder muscles are failing to do is causing half of the pain.
“Oh, I have 100 yen here.” Katsuki feels the cold coin drop into his lap, but he can't take it. He can't move his hands. “Well? Are you gonna go or just sit there and wet your pants?” Katsku looks up, feeling like he could cry but forcing himself not to.
“Can't get up, I'll piss if I move.” Katsuki manages a full sentence, a sentence that gets a jolt of something to spread across Totodorki’s face.
“Well, shit.” Katsuki has to hold back a laugh, Todoroki cussing was not on his summer bucket list, but neither was pissing himself.
“Shit, fuck.” Katsuki feels it, all of his resolve leaving him. A warm burst of liquid rushes into his hands. He quickly removes one from inside of his towel and grabs the outside, pushing it up against himself to catch the piss slowly leaving him. He cant stop it, the trickle is gaining traction and fast. “Im pissing, Fuck, Icy-Todoroki! Help! Fuck-” Katsku panic’s he can see the first few drips leaving his lap and splattering on the ground below him.
“Uh-” Katsuki can't look up from the towel in his hand, rapidly soaking with his urine, he's not feeling any relief, only panicking as the towel gets wetter and wetter and moving obvious drips patter into the ground below him. He see’s motion in the corner of his eye. “Oops.” He hears the remake before he feels it,
“Ah! shIT- oh my fuck!” He practically jumps up from his spot, ice cold water from a water bottle is being poured over his head. The cold quickly meets warm as he loses all control. He is peeing, uncountably at this point. A hot, warm stream is flowing with such force out of him that it is arcking from his crotch, the speedo might as well not even be there at this point. He quickly shoves the towel back over himself and pretends to be drying his wet chest off from the water bottle.
“Stop for a second, it's obvious.” Todoroki whispers to him. He knows what he is saying, He can see the water bottle water isn't dripping off him enough to hide his accident anymore, the amount of liquid leaving him is far too intense, but it takes him a while to convince himself to stop. He does manage to stop it.
“You have five seconds to help me before I’m pissed again, I'm not joking.” Katsuki grunts, the pain from stopping is almost as bad as when he was holding himself.
“Race you into the water!” Todorki screams, taking off running from their spot, He looks over at Ida who looks over at him and nods, giving him the okay to get into the pool. He notices the girls are not there and starts to take off. The second he is running, it's all over. Piss is flowing down the inside of his leg, he can feel it picking up speed, but it doesn't matter because he cannon balls right into the pool. Finally, he can relax. And he does. He lays back into the water, the waves from his cannon ball moving him around slightly as he releases five water bottles and a large slushy worth of piss in the water.
The water around his crotch is warm and it feels weird in contrast to the cold pool water. The tingly sensation from before is now all over his body as he pisses, he swears he has never needed to go so badly in his life.
“Heh, feel good?” Todoroki’s voice suddenly in his ear causes him to open his eyes, he didn't even realize mid-relief he had closed them.
“You realize you're like, swimming in my piss right?” Katsuko teases, feeling his stream start to taper off, leaving his midsection feeling sore but empty.
“You realize with a 100 yen charge to use the toilet, this pool is probably 98 percent pee.” Todorki says, closing his eyes “99 percent now.” he smirks.
“Ha- You know what, your alot less fucking annoying in the summer.” Katski shoves Todoroki, who splashes water back at him,
“Ew, don't splash me with the piss water!” Katsuki laughs, feeling so much better, and now that he doesnt have to pee, he realizes he could actualy use a bottle of water, considering how fucking hot out it is.
