Under the rule of enduring the urge to urinate over time, this work lets you enjoy watching women struggling to hold it in front of a hidden camera. As the intense need to pee sets in, each woman displays her unique way of resisting. When the timer goes off, another new timer appears—but they aren't told about it, making their reactions upon opening the box a highlight of the episode. They keep enduring relentlessly, sharing personal stories about their urges, pressing their fingers against their crotches, wriggling their legs and hips, desperately fighting the sensation. Just as they feel relieved thinking the time has passed, they open the box and show shocked expressions, only to be forced to continue holding once again. Those who endure are measured for urine output, with their bladder distension and other details recorded. In this installment, four women end up wetting themselves. A cute-faced office lady appears, fidgeting cheerfully, muttering "Ah, crap, crap…" before suddenly leaking without warning. Her shifting expressions reveal complex emotions. Miu, an apparel shop worker, squirms nervously while summoning her willpower to resist; when the timer rings, she triumphantly shouts, "Yeah! I won the challenge!"—only to be crushed by the second hidden timer waiting for her. Haruka, the bespectacled beauty, writhes her long, slender legs and rubs her belly while holding in, but when she finally gives in, pale yellow urine slowly trickles out from under her buttocks. The quiet office worker Miyu firmly presses her thighs together, standing and sitting repeatedly to endure, but her shaky, timid resistance doesn't last long, and urine begins seeping through the gap in her skirt. Energetic nursing student Mari patiently waits as time passes, toughly enduring even the most intense urges, and upon completing the challenge, she finally unleashes a liberating, powerful stream—releasing a massive 950cc, astonishing viewers with her incredible stamina. The main feature includes clear facial shots, allowing you to fully experience the realism of their struggle.
