In a room equipped with four unmanned cameras, this documentary-style video captures sisters in casual clothing desperately holding in their urine. Starting with a strong urge to pee, they are forced to endure until a timer goes off. During the wait, they fidget nervously while sharing personal stories about urination, pressing their fingers against their crotches, squirming their legs and hips—visibly struggling to hold on. When the timer finally rings, they begin urinating as a release of their prolonged restraint. Afterward, the volume of urine expelled is measured and displayed on screen, along with their bloated stomach sizes (excluding certain areas). A new twist is included: participants must open a box after the timer to receive the next instruction. Pissing scenes are edited in dual angles for better viewing. This installment also features a girl who accidentally leaks. The concept originated from email exchanges with supporter A-san. Through the unique personalities and intense bladder control of these women, we hope viewers experience a powerful fetishistic thrill.
