Leah opened her mouth to try to talk to Tina about this, but only a grunt came out. She bent even deeper into her squat. She couldn't feel herself pooping, but she could feel the poop entering her thoroughly soiled underwear. A massive log began to snake out of her ass, pushing out the seat of her underwear and jeans.
"Oh, son of a-" Tina threw her hands up in the air. "All right, that's it. Don't tell me what's going on, I'm just going to get you some diapers, because you, young lady, are making the biggest poopy I've ever seen!" Tina stormed out of the bathroom, leaving Leah alone, still pooping.
Leah grunted again as her body finished pushing out the log. But she wasn't done. More farts sputtered, accompanied by a sticky, hot mush she could feel spreading over her butt. Even so, that wasn't what she was most upset about right now. She was most upset that Tina had just prevented her from explaining her situation. Sure, Leah didn't quite know what was going on, but what little she did know would have been good to share with Tina! Hopefully, Tina was just frustrated and would insist on Leah telling her everything once they got home.
Leah bent deeper into her squat, pushing out more and more poop. All she could do was wait for it to be over at this point.
By the time Tina returned, Leah had filled her underwear to bursting, resulting in poop running down her legs, but she still wasn't done. Tina was, to put it mildly, pissed.
"Finish up," Tina snapped. Leah suddenly pushed with massive force, following Tina's command. A final salvo of poop and farts exploded into her underwear. Leah straightened with a sigh of relief. She swayed slightly as she stood, her balance thrown off by just how much poop was packed around her butt. "Done?"
"Yes."
"Good." Tina looked at Leah in disgust. This wouldn't be easy for her to clean up. "Let's get you changed."
It took a lot of baby wipes, soap, and water, but after fifteen minutes, all of Leah's poop and pee had been cleaned off her and the bathroom floor. Leah sat on the baby changing station, testy that she fit it perfectly fine, wearing only a diaper. It felt incredibly thick. No doubt designed to hold messes of the caliber that had just exited Leah's body. Tina put a rubber diaper cover over the diaper, for additional protection, then pulled a T-shirt with a butterfly on it over Leah's head.
"No bottoms?" Leah asked. Tina shook her head.
"If you have a mess like that again, bottoms would just make cleaning you up take longer and be more difficult." Tina threw away all of Leah's clothes, which had unfortunately gotten messy during her protracted accident. "Now. Let's get out of this bathroom and finish shopping." Leah nodded. She wanted to get home, where she hoped Tina would remove the ban on telling her what had just happened. Tina lifted her off the changing table and set her on the floor. Leah wobbled a bit, not used to the massive bulge around her waist, and fell backward. Thankfully, the diaper cushioned her fall. She barely felt it.
Leah got back up and followed Tina out of the bathroom, waddling like a toddler due to the thick diaper pushing her legs apart. As they exited, she glanced back at the strange machine in the corner. Hopefully, that mystery would be solved soon.
