Chapter Text
As her luck depleted with every place they visited, her desperation increased. Just as she thought about going into an alleyway and taking a dump on the ground next to a garbage can or something, one of her friends alerted her to a nearby convenience store that wasn’t closed yet. They all went in and she begged the person behind the counter to let her use the bathroom, saying it was an emergency. Hearing that she was actually allowed to use it sounded like music to her ears and she practically ran to the back of the store, her friends secretly following her, before rushing into the small single-occupancy restroom.
The end was in sight and she truly felt like she’d make it without having an accident. Although she struggled to pull down her pants and shart-stained panties, her butt furiously shaking from side to side as she tried to keep herself from pooping prematurely, they eventually fell from her waist and pooled around her ankles. With no more time to waste, she slammed her ass down on the toilet.
The moment she made contact with the seat, the loudest, wettest fart she had ever produced in her entire life exploded out of her. When it died down, she grunted and leaned forward slightly as a big, long, soft turd quickly and easily slid out from between her cheeks, plopping sloppily in the toilet and poking out of the water. A harsh torrent of liquid diarrhea poured out of her dilated asshole immediately afterwards, completely turning the water brown.
She tried her best to stifle her moans of discomfort, as she was embarrassed enough that her unexpected dump made the bathroom sound like a nuclear war zone that was most likely audible throughout the convenience store. Every once in a while, though, a gasp or groan would escape her lips after a particularly rough fart or wave of diarrhea.
Even after things would seemingly calm down and make her think she was finally finished, her belly would let out an angry growl and another explosive fart would propel more watery poop into the toilet. She would be there for a while.
Outside the bathroom, her friends quietly giggled to each other as they listened to her shit her guts out. They originally hoped she would make a mess in her pants, but the sounds of her absolutely destroying the toilet were satisfying enough.
