"I shouldn't have..."
"I shouldn't have drunk that entire bottle of water before boarding!"
Kioshi the Greninja was regretting a lot of things right now. His first regret was not using the bathroom before boarding his flight. His second regret was chugging a one-liter bottle of water before boarding the flight. And his final regret was not packing a change of clothes in his carry-on. He just ended up drinking all of that water so quickly due to his sore throat, but it all had to go somewhere. On the bright side, he was wearing black pants, so if he did have an accident, the damage wouldn't be too visible.
The flight hadn't taken off, so he couldn't use the bathroom. He was still able to keep his phone off of airplane mode at this time, so he took an opportunity to text his friend Nieve.
"Not sure if I can keep my pants dry until this flight takes off," he texted.
He then set his phone down and made an effort to pretend his intense urge to pee didn't exist. He tried to think of literally anything else - dragons, video games, sex, whatever - but his mind continued to wander back to the fullness of his bladder.
His phone buzzed; Nieve had texted him back
"LAWL! Have fun bby, think about waterfalls in the mean time ;)", the text said.
"Ha ha, very funny," Kioshi texted back.
Right after the text sent, the airplane started to taxi and Kioshi had to set his phone to airplane mode. At least the flight was taking off soon and he'd be able to pee. He put his headphones on and started listening to music to pass time until the flight took off and finished ascending. The music helped to take his mind off of his filled-up bladder; however, this would also prove to be his downfall as Kioshi got so into his music that several minutes had passed between when he could get up to pee and when he realized it.
"Fuck," Kioshi thought. "Well, better get up to piss."
Kioshi got out of his seat and started walking towards the bathroom, only to realize a very inconvenient truth: There was already a line.
"Shiiiiiiit," Kioshi thought.
Kioshi stood in line, standing perfectly still so as to not draw attention to himself. Whoever was in the bathroom at the time was clearly taking a while, as 10 minutes had gone by and they hadn't gotten out. Finally, after about 20 minutes, they got out, and the line started to go by faster as others didn't take so long. Everything looked good for Kioshi, until the flight hit some turbulence right when he was next in line and he had to sit back down.
"Ugh," he thought.
Kioshi returned to his seat, defeated. It seemed like he was going to pee his pants no matter what he did. He did have a soft spot for omorashi ever since he had a pee accident in Nieve's car, but he didn't want it to be like this. Not when he didn't even have anything to change into.
He put his headphones back in and sat perfectly still - if he visibly showed desperation, he'd draw attention to himself. He also repeated a thought in his head that if he started peeing his pants, he would not react to it in any way so as to avoid others realizing what was happening. All was well for a few minutes, until his desperation became so great he ended up squirming visibly no matter how hard he tried not to, which drew the attention of a female Haxorus sitting next to him.
"Having fun?", she asked.
Kioshi removed his headphones and said, "Made it through worse."
"... Right..."
The Haxorus went back to reading her book while Kioshi just sat there trying his absolute hardest to keep his pent-up pee in his bladder until he could get out of his seat and pee, but it didn't look like that was going to happen.
Kioshi suddenly froze. It had reached the point where if he moved at all, he would piss himself. He had mere seconds left before the floodgates opened up.
"No... No no no," Kioshi thought.
All of a sudden, the floodgates opened and Kioshi was peeing his pants and couldn't stop it. However, he didn't utter a sound and pretended to be oblivious to the whole thing in the hopes of no one noticing. However, someone did notice - the Haxorus sitting right next to him, who reacted by quickly covering up Kioshi's pants with her hoodie.
"There, there," she said. "It's okay."
"I still peed myself... Ugh, could this day get any worse?"
Right when he said that, a kid started kicking the back of his seat.
"Yes. Yes it can."
"Did you bring something to change into?"
"No..."
The Haxorus opened her bag and showed Kioshi a pair of jeans and a pair of pink panties - both urine-soaked.
"I had a little accident on my previous flight," she said. "Helps to have something to change into."
"Clearly I should have prepared... But I feel like it'd make me behave in a riskier manner."
"Like, you think you'd end up being less responsible with your bathroom breaks knowing you can change anyway?"
"Yeah, that."
"That happened with me, but even if your behaviors change somewhat, at least you're prepared for the worst-case scenario, unlike what happened with you..."
"I guess..."
The Haxorus looked at the puddle at Kioshi's feet and was astounded by its size.
"How long were you holding it in?"
Kioshi shrugged and said, "I didn't really pay attention to it until after I boarded the plane."
"Did you drink a lot of water?"
Kioshi nodded.
"Yeah, that seems to be how it usually happens. All of a sudden, you just really have to pee."
The next few minutes were spent in silence, with the Haxorus reading her book and Kioshi listening to music, until the Haxorus tapped Kioshi's shoulder.
"By the way," she said. "I don't believe I asked what your name was."
"Kioshi."
"There's a Kioshi in my math class... Have we met before?"
"Are you in Professor Mew's class?"
"Yeah. My name's Edna. It's nice to meet you, Kioshi."
"Small world, isn't it? ... You'll keep this a secret, right?"
"Ha, of course. It's not like I have any room to talk, anyway..."
After another hour, Kioshi again felt the urge to pee and just peed his pants again. He couldn't possibly do any more damage to his dignity.
"Didn't feel like getting up?", asked Edna.
"Just figured I couldn't possibly make things worse anyway," said Kioshi.
"True. The damage is done."
Edna got up to go use the bathroom, but the flight suddenly hit turbulence again and she had to sit back down.
"Ugh... I really gotta go," she said.
"You don't happen to have another failsafe, do you?"
"No, but this is why my failsafe is always a leather skirt."
Edna pulled up the front of her skirt and then purposefully peed in her white panties, while using her pissy jeans as a sponge to prevent any of it from going over the front of the seat. Once she was done letting loose, her panties were so see-through that every detail of her vagina was clearly visible.
"Wow," said an aroused Kioshi. "I had a friend who did the same trick..."
"Is she a Glaceon named Nieve? I learned it from her."
"Yeah... This is a really small world, isn't it?"
The remainder of the flight was spent with the two of them casually chatting while also freely peeing if they ever felt the need. Once the flight landed, the two of them went their separate ways, but met up at the same 1985 Toyota Corolla, which is when they realized they were being picked up by the same Pokemon.
