"Not at all. About 6 this morning."
"Holy shit," Kelsie said, "you've been holding both for 12 hours?? That's badass! I don't know that I could do that."
Heather grunted a little more loudly and said, "Hnnngh... I'm about at my limit though, I usually go straight home and destroy my home toilet, and that would be right about now. I'm about to have an accident!"
"Well," Lauren said, "I think you just need to prove to us you really do deserve to use our toilet, and we'll think about it."
"What?? Mmm... uuugh... oooh... how do I... hnnnngh... do that?"
The girl sounded like she was barely holding it all in, and the potty dance basically confirmed that.
"Walk us through your history of holding," said Kelsie, catching on to what Lauren wanted, "where it started, why you still do it, what your holds look like, and what you'd want to try if you could, things like that."
"But I have to go right now!"
"So do we," Lauren said, "so start talking and maybe you can use the toilet before it's too late."
Heather started detailing her earliest experiences holding everything in a house with only one bathroom, as well as at school where she was often shy. She mentioned she started really enjoying holding, and would often come home from school bursting, only to find the bathroom in use, and would be forced to remain desperate that much longer. Sometimes most of the family would come back around the same time, and she would let everyone go to the bathroom first. She'd tell them she was fine and could wait, lying of course, just to intentionally deprive herself of relief even longer. Many times she'd leak in her panties before she could get in the bathroom, or a giant shit would make its way out, turtlehead and sometimes make some stains in her panties. It was rare she had a full-on accident as she could usually judge her holding ability quite well. One time in her later high school years, she did misjudge it, as her mom had invited a friend over to talk about some college prospects for Heather. Heather had of course forgotten as she was busy desperately holding in three days worth of bowel contents and a day full of pee. When she got home very ready to finally use the bathroom, the friend was on the couch and ushered her over to talk, and Heather had to shyly submit to a talk about college while desperately trying not to piss and shit her pants. The talk went on for nearly an hour, during which Heather could have likely excused herself but didn't. Thinking she could wait, she held till the end, when a leak darkened her panties, and her poop was actively pushing to get out, only held against the seat of her panties by her tight ass pressed against the couch cushion. When she finally made her excuses, she was in an emergency situation, and wasn't sure she could make it to the bathroom. She finally dashed to the bathroom, shit moving the whole time, pee leaking, and completely pissed and shit her panties under her skirt within sight of the toilet.
She finally detailed a later experience, where she'd held it leading into graduation. As she was starting this story, Lauren and Kelsie were squirming against the pressure in their full bladders, and they could tell Heather was doing everything possible to avoid pissing and shitting herself. She told them how she'd gotten excited to hold it during graduation just because it would be naughty to be desperate while getting her diploma. So, she started holding a couple days before, so she'd have a nice big load knocking on her back door, and didn't pee when she woke up, knowing she'd become very desperate by the time she walked up to get her diploma at around 11. And, she had said, with the graduation gown and her dress underneath, if she lost control no one would likely know unless she was obvious about it. As the morning went on and she put up her hair and did makeup, Heather was openly squirming in desperation, still holding everything in. She promised herself she wouldn't be too obvious as the time came to sit through the ceremony and walk up for her diploma. Hopefully she could make it right to a bathroom as soon as it was all over. The time for the ceremony finally arrived, and the drive there was pure torture, her bladder and bowels nearing max capacity, and the idea that relief was impossible for at least another hour made Heather shudder with arousal. She was slightly wet thinking about how naughty she was being, denying herself a bathroom and bringing herself so dangerously close to an accident in public at her high school graduation. Still, she had to contain her bladder and bowels, her desperation, and her arousal from it so no one would know she was bursting under her cap and gown.
Finally, as the ceremony started, she was prairie dogging, and her bladder was nearly full enough to start leaking. Still, she held it. A couple of speeches which were likely heartfelt and profound but which she ignored as she focused on not exploding in her seat. Then the procession of students lining up to get diplomas. Luckily, she was early in the lineup and didn't have to wait long. She mildly squirmed standing in line waiting for her turn, then as she was only a few from the front, her poop made a push to the exit, and she squeezed and squirmed slightly trying to keep from unloading. It worked, and she only lost a leak of pee, but was prairie dogging badly now, unable to keep the poop fully in her rectum.
Finally, it was Heather's turn. As she walked up to shake hands with the Principal and Superintendent, her poop was slowly moving again, and another small leak dampened her panties more. She was graduating from high school while effectively in the midst of having an accident in her panties. It was such a turn-on, she had a hard time keeping a straight face while trying to contain her needs. She finally walked back to her seat, standing with everyone else while the rest of the class received their diplomas. Heather was nearing her end, with her poop now firmly connecting with the seat of her panties but still lodged in her rectum. She was slowly leaking pee, and hoped she could keep it to a slow leak so as not to be too visible.
Graduation ended and she threw her cap in the air with the crowd, and went to find it afterward, getting with her parents for some pictures. At this point her pee was starting to trickle down the inside of her thighs, but she was still bursting. Her poop had tented out the seat of her panties and was starting to coil up in the seat as more kept coming out very slowly. Heather was powerless to stop it, she had simply held it too long. She tried to maintain composure as she filled her panties, smiling through the pictures and unable to escape to a toilet. Finally, her parents and a few friends were done taking pictures, and Heather said she had to visit a bathroom as she was bursting, which was no lie. She tried not to seem like she was waddling with a load in her panties that was still coming out as she went to the arts building to find a toilet. When she entered the building, she knew she was out of time. Her bowels finally pushed the last firm log into her panties, and her bladder pulsated. She quickly waddled into the bathroom, and before she could even get into a stall her bladder leaked again and Heather knew it was all over. With no time to do anything else, she quickly lifted her dress and gown, then squatted hastily over the floor drain as her bladder burst through her panties into the drain. When her pee was finished, Heather admired her load in the mirror for a moment, relishing how naughty it was that she'd gotten away with an accident at her high school graduation. Then she carefully waddled into a stall where she took off her gown and dress, then slid her panties down her legs and dumped the giant pile of shit into the toilet. By some miracle, there were only light poo stains and a big wet stain on the crotch and butt of her panties, but she thought it best to dispose of them anyway. She cleaned herself up, then met her parents for a celebration lunch going commando the rest of the day. No one ever knew about that.
When she finished that story, Heather grunted, groaned, and started panting. "Please, I have to... nnngh... go... aaah... right now!"
