Four unmanned cameras are set up to capture a unique documentary featuring sisters in casual clothing enduring intense urges to pee. Already feeling a strong need to urinate at the start, they are forced to hold it until the timer sounds. Restless and visibly anxious, they shift their bodies constantly, sharing personal stories about urination while desperately struggling to maintain control. The footage realistically captures their limits—pressing fingers against their crotches, twisting their legs and hips as they fight the overwhelming urge. When the timer finally goes off, they begin releasing their long-held streams. Each woman's distinct way of enduring creates a powerful fetishistic appeal. Leveraging the signature traits of the Female Excretion Sect, this is a shocking and intense documentary work.
