A film following the rule where women attempt to endure their growing urge to pee in front of unmanned cameras over time. Starting already with a strong need to urinate, viewers can enjoy each woman's unique way of holding it in. When the timer goes off, another timer is added (+16 minutes), but the women don't know this—making their reactions upon opening the box a key highlight. As they desperately endure, they share personal stories about peeing, press down with their fingers, and move their legs and hips in frantic attempts to resist. Their relief at thinking time has ended is short-lived, as opening the box brings shock and disbelief, leading them to curse while still struggling to hold on. Those who endure undergo urine measurement, with their bladder swelling also recorded. In this installment, three women end up wetting themselves. [Tomoka] Now a regular staff member of the sect. Despite her responsible appearance, she repeatedly breaks the rules by moving around freely even before time's up. She's known for suddenly squirting out pee uncontrollably. [Konatsu] A simple office lady whose endurance style is highly distinctive—she performs a never-before-seen technique called "push-up-style inner-thigh squeeze hold." Her genetically intense endurance form is a must-see. [Anna] A quiet OL with striking narrow eyes. Gradually, her hands drift toward her crotch in a sensual manner. Her intense climax of urinary pressure, pressing hard against herself, is spectacular, and her post-endurance pissing is equally impressive. [Aya] An OL with an anime-like voice. Her mature looks contrasted with her high-pitched voice create a moe appeal. Poor at enduring, her flustered expressions when leaking add strong realism. [Mizuki] Attractive for her long limbs and husky voice. She appears braless for some reason. After the trap activates, she tries counting sheep while enduring, becoming increasingly confused. She repeatedly cries out erotic lines like "I wanna pee, it's getting hot, help me!" The main footage includes full facial exposure.
