It was about this time that both Lori and Erica felt their bladders send sudden signals that they couldn't wait much longer for relief. Both crossed their legs, and they each caught the visual cue, both winking to say they'd hold it until Anna was finished.
Anna squirmed and crossed her legs for a second, then started telling about how as a young girl, she was always holding it all in. It had started so early she hadn't quite remembered when it started. She did say that it was always a fascination of hers. She'd often try to pretend she wasn't holding, act like she wasn't desperate, but in a family of five in an average sized house, there weren't many places to hide, and someone would often call her out. Eventually, the reality sunk in that no one could stop her from holding, so even her parents stopped trying. They'd just try to be aware of where the nearest bathrooms were if they left the house with Anna, so she didn't have too many accidents.
She did have some pretty big accidents over the years, and she started telling about some from her earlier years. She excluded the ones before getting out of elementary school, because those she referred to as "kid" accidents which really didn't count.
Her first key experience that she officially counted was in her freshman year of high school. She had started the day by skipping her morning pee, planning on holding her bladder through her school day and allowing herself relief only when she got home. She was so excited for a good hold, she had forgotten they had a field trip that day to a museum in the big city a couple hours away. She got to her first class, the teacher announced they were loading up on the bus in a few minutes, and Anna instantly thought, "Oh shit, this is going to be a long day."
She loaded into the bus, feeling her somewhat full bladder, knowing she wouldn't get relief for many hours. She held on, and tried as long as possible to pretend like she was totally fine. She chatted with friends, followed the guided tour, had lunch, made fun of the stupid boys, the whole time feeling her bladder steadily filling. By the time the field trip was done, and they went to load into the bus again, Anna was quite desperate to pee, and she still had a couple hours before she could use a bathroom. She'd likely need to use a school bathroom as she might not be able to wait until she got home. She got in her seat, crossed her legs tightly to stem her desperate need for the long drive home, and hoped for the best. The drive was an eternity, and Anna couldn't remember a time she'd had to pee this badly. They finally got back to the school, and her nightmare came true. The school was already locked up. She was forced to wait for her parents to pick her up, on the verge of pissing her panties. They did finally show up, realized she was desperate and calmly said, "Don't piss in the seat, we'll be home in a few minutes." They got home, Anna scrambled into the bathroom, and pissed her panties right in front of the toilet before she could sit down.
She noticed both Lori and Erica were squirming after that story, and picked up on their desperation. She was really desperate to shit, and couldn't hold much longer, but maybe by telling more stories she could make them piss themselves.
Anna at that point said she was frequently desperate for a piss, shit, or both throughout her high school years, and watched the other two squirm more.
Anna's next significant story came during her sophomore year. She had been holding three days of shit, having started on Friday and holding through the weekend. As Sunday came to a close, she was prairie dogging every so often, and knew she'd likely need to go before school in the morning to avoid an accident. She went to bed seriously bursting to poop. When she woke up, a little late due to poor sleep, she realized she could only pee for now, but might not have time to poop, so she peed and held in her urgent shit. After getting ready, she realized she had a few minutes, and wandered to the bathroom intending to poop, but one of her siblings was doing the same. She checked her parents' room and her mom was pooping. There was no free bathroom, and Anna was forced to hold her poop into her school day.
The day went painfully slowly. Anna kept prairie dogging, sucking her massive load back in, and occasionally letting out little farts to ease the pressure, but her desperation never let up. The worst part that day was every time she went to a bathroom, all the stalls were occupied. She kept getting forced to hold in her beyond urgent dump for even longer, bringing her ever closer to shitting her panties.
Anna could tell through her own desperation telling the story that Lori was intrigued, and knew she had to ask later about that. Lori asked what happened that day.
Anna resumed the story, saying that she kept getting denied relief at every turn, and by her last class she was actually starting to have an accident, but she was able to hold the turtlehead in place just long enough for the class to leave for the day. Then she carefully got up, started walking to the front to await pickup from her mom, but shit herself in full view of about a dozen other students.
When she finished that story, Anna was squirming badly and asked with major tension in her voice, "Can I please go poo now?? I'm about to explode!"
"Not a chance," Lori said, "there's no way those are your only stories. You're not done yet."
Anna groaned, squeezed her legs tightly together, and said, "Fine, okay."
She briefly composed herself and told her next story which happened junior year. She was dating a boy, but he didn't seem to be aware of her holding obsession. He was a senior, and would be leaving for college in the fall, so the relationship couldn't last, but it was fun for a brief time. When his senior prom came around, Anna and he had become close, so he asked her to prom. She of course said yes. By this point, Anna said, she had become quite skilled at hiding her desperation, and delaying her relief. She decided she had about no choice but the plan a prom hold. So as the last few days to the prom drew to a close, Anna started holding her shit. She wanted prom to be the night of day four, so she'd be hovering on the edge of her control all night, barely able to keep her load in her bowels. Then as she got home, she'd shit her panties struggling to get her fancy dress off. The universe had different plans. She managed to get through the pictures, the prom, dancing as little as possible claiming she had a mild stomachache. Of course that was partly true. When prom was about to end, her boyfriend had surprised her, taking her to his car and driving to a beautiful scenic overlook for a romantic end to the night. Anna was in panic mode the whole time. Her plan was being delayed, and not only was she on verge of shitting her panties, but her bladder was extremely full too. She asked if he could bring her home in a few minutes, reminding him of the stomachache which she said was getting worse. He seemed genuinely concerned, and said he'd bring her right home. She thanked her lucky stars, still trying desperately not to explode on his car seat the whole way back to her house. He got out to kiss her, and as they were in mid-embrace, Anna lost a leak in her panties and her poop launched out a couple inches until it stopped against the resistance of her tight panties. She maintained her composure through the kiss, then excused herself, saying her stomachache was not just a stomachache with a sheepish grin on her face, and scrambled inside, only to piss and shit herself at the door of her bathroom having misjudged the timing.
