Flooding the elevator (Nichijou)
At first, it had just been annoying...
Then, after a while, boring...
After an eternity, it became mind-numbing...
Then, suddenly, funny...
Quickly followed by maddening...
Only to fall back into boredom, again... and, finally, desperation.
The girls didn't know how long they had been stuck in that elevator. They didn't know if or when help would arrive. But they certainly knew one thing, after all this time of just waiting around.
They all urgently, desperately needed to pee.
It was inevitable, really. They could only hold out for so long and by now their bladders were near bursting, forcing the girls to do something about it.
But it wasn't like they had any options...
"Mio, I need to pee...!" Yuuko eventually complained, loudly and miserable, her hands shoved into her crotch. She got up from her position on the ground to try the buttons once again, knowing that it wouldn't do anything.
Mio showed a bit more tact, but it was obvious that she was also near her limit, judging by her shivering thighs, which she quickly crossed together. On the other hand Mai didn't seem to show any outward discomfort, but that was only because she still felt paralyzed, as she laid there on the cold, hard floor...
"Come on! Come. on!!ComeoncomeoncomeonWORKALREADY!!"
In a fit of rage and strength that would've made Mio proud, if she wasn't dealing with her own problems at the moment, Yuuko kicked the panel of useless buttons. Hard.
...And immediately regretted it, as that made her lose her control for a second. She quickly felt her panties grow warm, just a tiny bit. To make it extra clear what had happened, the girls could also hear several heavy drops hit the ground, the sound of them greatly amplifying their own need. All three shivered in unison.
With nothing else to do Yuuko crossed her legs and tried a little potty dance, while airing out her frustrations to Mio.
"Uhhh... I... I need to pee so bad...!"
"Ugh! I know..."
"Why can't they just install emergency toilets in these elevators for those situations?!"
"I don't know, Yuuko."
"If I had a toilet right now... or, heck, just a bucket, I would just-... I mean, I could really-!"
"...please stop talking..."
"I might just pee for minutes, you know? That's how full I feel."
"For god's sake, I said stop. talking!"
In an effort to get Yuuko to finally shut up and to also maintain control over her own failing bladder, Mio quickly pulled out the first object she could find in her pockets and threw it at her friend's head with force. It did the trick and the brunette immediately closed her mouth.
Many more minutes passed, while the friends all suffered in deafening silence, the urge to just let go rising by the second...
Yuuko was the first to give in. The brunette had been right in the middle of her fourth potty dance, when she felt her bladder suddenly contract and leak again, straight into her panties. Realizing that it was only a matter of minutes, if not seconds, before said panties would be completely ruined, the girl made a quick decision.
"B-both of you: D-... Don't look!"
It was pointless. Of course Mai and Mio would look, after Yuuko had said it all nervous and begging like that. And so the stunned girls were immediately treated to the sight of their friend twitching and jumping in place, while she urgently pulled down her panties; all while little drops kept falling down between her shaking legs.
Once her underwear was safely out of the way, Yuuko took a squat and started to piss. Full force. A loud, almost orgasmic moan of relief escaped the brunette, as her heavy urine sprayed all over the floor, quickly creating a sizeable puddle which grew... and grew... and grew...
The sight of said puddle and of Yuuko's euphoria quickly drove the two other girls towards the edge. Mio got lucky, as she clamped down on her lower muscles just in time to prevent a major accident.
Mai... not so much.
The poor girl gave off a full shudder, as she tried in vain to get her tired, paralyzed body to move, to prevent the inevitable... but it was no use. With Yuuko's stream still loudly splattering onto the floor, Mai's bladder gave out as well, releasing its own hissing stream straight into her underwear. It didn't even take five whole seconds before her panties and skirt were completely drenched and dripping, as her pee created a second puddle that spread out all under her butt and legs. A crimson blush coated Mai's cheeks and she bit her lip in agony, as she tried to not let out any revealing moans, as much as she wanted to.
As both puddles quickly joined together, creating one large one, Mio was forced to jump up onto her feet, to keep her butt dry from the rapid deluge. And then she shivered violently, as her own bladder sent out a painful pang of need.
She needed to pee, so, so bad! And she had the perfect opportunity, the perfect excuse, right now. After all, her friends couldn't criticise her when they had started it! And since they had already ruined the floor Mio's pee wouldn't do much of a difference.
And yet she still held herself back, out of a misguided sense of pride and shame.
Too bad her body didn't share her sentiment.
"Ah!!" She gasped in horror, as she suddenly felt herself leak. And it was a big leak. Again she tried to delay the inevitable, but her bladder was having none of it. It quickly began to pee on its own in erratic, sudden spurts, which heavily saturated her panties and then dribbled onto the floor, right into the giant puddle her friends had created. Mio grit her teeth in shame and anger, her face heating up.
Then, throwing her stubborn pride to the side, she pulled down her panties in a great hurry - so great, in fact, that she didn't even notice her underwear landing into said puddle with a wet, resounding splat - spread her legs wide open and relinquished all hold over her muscles.
More spurts quickly followed, short and weak, as if some part of her mind was still trying to hold itself back, conscious of her live audience. But after just a bit more relaxing, her bladder finally got the message and fully opened up.
A loud splashing filled up the elevator, as a forceful and desperate torrent shot out of Mio, eagerly feeding the existing ocean on the ground and making it spread even further, until there was literally no dry corner left in here. Shivering violently Mio closed her eyes in bliss, as all the tension and frustration rapidly drained from her body.
Ah, sweet, sweet relief......
Suddenly a bright light blinded the girls, as the power returned to the elevator. Before they could get their bearings, or even stop their peeing, the doors opened up, revealing two maintenance workers.
Things immediately turned... awkward.
Four shocked and wide eyes stared inside the elevator. All three girls panicked, trying to shield themselves, but with their bladders still achingly full it was no use. In full view of the men they had no other option than to finish their long, shameful business, completely flooding the room.
In light of the torturously slow response time of these maintenance workers, they decided to not chew out or bill the girls for the extra damage. Still, once the three finally stepped out of the building, breathing the fresh air outside and feeling the warm, drenched clothes on their bodies, they all made a vow to never speak of this day again.
