Lauren had given herself a break of a few weeks to just go to the bathroom as normal, though she had let herself get very desperate to pee a few times, once almost resulting in an accident on the phone with a friend a week earlier. She had often been constipated, going every three or four days between bowel movements, which had become her new normal. She never remembered being constipated this often when she was younger, but her body had obviously changed. She was heavier than when she was younger, but still considered herself to be quite attractive. Anyway, constipation was now a regular part of her life, and she kind of enjoyed building up giant bowel movements, and now often enjoyed becoming desperate to poop, but holding her load inside her bowels to get even more desperate. She also now enjoyed getting so desperate that she could no longer hold it and was forced to shit her panties. The desperation, the release, showing her desperation in public, getting herself off both full and after an accident, it all aroused her. That's why Lauren couldn't go too long without indulging in her pleasures.
Lauren had last pooped on Monday, hoping that she'd finally feel a need on Friday, and she could hold it through her workday. She planned on getting home desperate, and being forced to poop her pants before she could make it to the bathroom. She would ultimately drink very little throughout the day, so her bladder was simply an equal issue and wouldn't force her to abandon her plan. To make things more interesting, Lauren purchased a small key lock which she would place over the button on her jeans so she couldn't use the toilet until she got home. She was able to close the lock without the key, so she froze the key in a cup of water on Wednesday.
That's where Lauren found herself on Friday morning, moving the block of ice to the refrigerator to thaw over the course of the day as she got more desperate. As she was getting dressed, she made sure to pee one last time so she was completely empty. Her bowels were quite full and heavy, but it felt good to hold it. She just hoped she could avoid going until she made it back from work and didn't have an accident in the office.
Lauren left for work after a big breakfast with little to drink. She sipped an orange juice but finished barely any of it. When she got to work, her jeans lock covered by her button down shirt, she got to work. It was an unusually quiet day, so she could focus on her urges as she needed to. Also, most of the office was gone by about 2:30 on Fridays, so Lauren knew when she got really desperate after lunch, she'd be able to openly squirm, hold herself and generally do whatever was necessary to keep her load safely inside her bowels.
Leading up to lunch, Lauren was desperate to poop, but she was in control. Her bladder had been filling but wasn't a serious factor just yet. As lunch approached, Lauren felt her rectum becoming very full, and right before lunch she had to fight back a major push which opened her anus and produced a fairly significant turtlehead. At this point, Lauren was worried she wouldn't make it the rest of the workday, but her turtlehead retreated inside her rectum again.
