"Okay," Kelsie said, "give me a few minutes to pay for what I've got and we'll go."
"Thank you, sweetie, I just didn't want a public accident, and Heather needs her bladder full first."
Kelsie of course understood, and wanted to make sure things went according to plan. She put away what she was looking at and walked to the register to pay for the one book she really wanted. It took a couple minutes, and Lauren and Heather were looking quite uncomfortable by the time she finished, and they walked out.
As they left the bookstore, Kelsie suggested they go to an oddities store, just for fun. The other two agreed, but were looking a bit tense as they walked, especially Heather. Kelsie and Lauren both wondered if Heather's bladder was filling yet, as it had been nearly half an hour since she had consumed three full drinks with her lunch. As if on cue, they passed a bathroom, and Heather said, "I need to go so incredibly badly right now, can I please go use the bathroom?"
"No," Lauren said, "we won't be here much longer, and I'm not going to shit in a public bathroom, I want to go home and poop there, you can wait until we're done, and we'll get home for your relief."
"But I have to pee and poo, I'm desperate for both!"
"You'll just have to wait for now," Kelsie said, "we won't be much longer."
Heather groaned and danced in place for a moment until Kelsie grabbed her hand and pulled her along toward the store.
As they browsed the store, Heather was becoming truly desperate. She was quite certain she wouldn't make it home without having an accident and wasn't even sure she'd make it out of this store without exploding. Regardless, she was holding everything in with every ounce of energy, because she wanted her inevitable accident to be as public as possible. Her desperate dancing was making both Lauren and Kelsie extremely aroused, although Lauren had to temper that with the knowledge that she also needed a bowel movement rather badly and hadn't planned on being this desperate today. She was starting to get worried she wouldn't make it home, so she told herself she'd get Kelsie interested in leaving soon.
A few minutes later, now about 45 minutes after Heather had downed all her drinks, she was struggling not to have an accident, and the other two could see it. Lauren also needed to shit badly, so she whispered to Kelsie that she was getting desperate to poop, and that they should get going. Kelsie finally relented, and they slowly made their way out of the store as Heather whimpered every 15-20 seconds fighting to keep from having a serious accident.
After leaving the store, somehow accident-free, the women walked by a bathroom once again, and Heather begged, "Please, I really need a bathroom now, I gotta go!" She was making a scene as a few people looked toward her, which was actually getting her kind of aroused. All these people knew she had to go to the bathroom badly. But it wasn't a huge crowd, so she had to wait a little longer. She was hardly able to think straight now, but she imagined the area by the food court and its bathrooms would be super crowded by now, so when Lauren and Kelsie denied her relief again, she resolved to hold it just another few minutes to the food court, and she confided this to Lauren, who was walking more slowly too because she was prairie dogging.
As they walked, Heather could feel her first log turtleheading, and it felt massive. She knew the rest wouldn't come out right away, but she was starting to lose control, which was the important part. She wanted to lose it before Lauren and Kelsie could deny her relief again so it became a "too late" scenario. As she was thinking this, a squirt of pee dampened her panties. This was going to be a close call.
For her part, Lauren could feel her first log prairie dogging as well, and simply hoped she could keep squeezing the load back in until they got back home. She mentioned this to Heather who said, "You better hold it if you're torturing me." Lauren accepted that willingly, and kept holding her load.
As they came up on the food court, Heather felt like she was maybe two minutes from losing control completely, though it could be less. She was keeping her legs tightly together, hands balled into fists, squeezing everything she could think of to keep from wetting and messing her panties, but it just wasn't working anymore. As they walked alongside the food court with the bathrooms in sight, Heather took a glance and realized there was a serious crowd. It had to be now or never, and with her control just about gone, it was going to be now no matter what. She looked at Lauren and Kelsie with pleading eyes and said, "I'm about to have an accident, I need to get in that bathroom right now!" A bunch of people turned her way when she said this, and she knew it without looking.
Kelsie turned to Heather and said, "We're going home now if you can just...."
Heather cut her off saying, "Oh God, no, no, no... it's too late..." Halfway through her statement, Lauren, Kelsie, and what seemed like about half the mall, watched as Heather's light red leggings turned burgundy as her bulging bladder emptied full force into them, down her legs, into her shoes, and onto the floor. A crowd was now turned toward her, watching the young woman in the middle of the mall pissing her pants as if she hadn't pissed all day. As they all watched, Heather felt her load suddenly pushing out of her asshole, creating a massive bulge in her leggings for the mall crowd to see. It took several minutes for her to finish, her face getting redder by the second, before the last of it finally came out with an explosive fart. It took a moment for Heather to break out of the trance of her relief, after which she suddenly came to the complete realization that nearly everyone within her sight was staring at her with mouths open, clearly shocked by her massive accident in such a public setting. She felt shame, but only a little. She felt arousal like she'd never felt before, and she realized she'd never felt so alive. She would absolutely be doing this again.
Finally, Lauren spoke up to break the crowd pause and said to the other two, "We need to go, I need to shit really badly, I don't know if I'm going to make it home if we don't leave."
"Okay," Heather said, "let's go so you can hopefully get your relief in private."
They walked out of the mall then, leaving a wet spot on the tile, and some drops trailing behind Heather's wet shoes for a couple hundred yards.
When they got to the car, Kelsie offered to drive as she had to pee, but not that badly yet, and the other two were in no place to drive. They all got in the car, Heather sitting gingerly to avoid the load spreading too far. They left for home then, Lauren making some light grunts as she apparently fought to keep control of her bowels. As they drove, Lauren seemed to be shifting around more and more, clearly very desperate to shit. For her part, Lauren felt like she was starting to lose control of this load, as she kept feeling it turtlehead further each time it came out, and knew eventually she wouldn't be able to squeeze it back in.
They were about ten minutes from home when Lauren felt it. She wasn't going to make it home, and she knew it. She thought maybe if she let some out, she'd get just enough relief to hold the rest. She was sitting on 5 days of poop though, so she wasn't entirely sure if that plan would work. As she was thinking about options, the point was settled by her bowels giving her load a massive push, and she felt her first log coming fully out of her hole several inches as she moaned trying to prevent it but failing. The other two women noticed, and Kelsie gave her a concerned look, to which Lauren said in a whimper, "It's coming out, I can't keep it in!" It came out over 6 inches, but stopped against the pressure of the seat cushion. Lauren started cramping immediately, and groaned, holding her belly. She needed this load out, but she also thought maybe she could make it back this way, so she didn't lift her ass off the seat the rest of the way back.
When they pulled into the driveway, Lauren carefully got out of the seat and waddled her way to the door, Kelsie right behind her fishing for the key. The load was slowly and painfully coming out more, and Lauren whined, "Please open the door! I'm shitting myself!" Kelsie quickly unlocked the door, and Lauren waddled through toward the bathroom with the other two right behind her. She reached the bathroom, turned on the light, but it was game over. Lauren was suddenly paralyzed as her load painfully came out, filling her panties so badly they sagged, and Kelsie and Heather saw the load under her skirt. Lauren was so relieved, she sighed heavily, then looked at the other two and said, "Well, I guess I don't need the toilet anymore."
