The 17th installment of the intense documentary-style series where women endure pissing in front of four unmanned cameras. Starting with strong urges, the participants are forced to hold their urine until the timer sounds. Even after the first alarm, an additional 16-minute timer begins, a signature cruel twist unique to this series. As they struggle desperately to hold it, they share personal pee-related stories, pressing their fingers against their crotches, writhing their legs and hips—every moment of their agony captured in raw detail. When the timer finally rings, brief relief turns to shock upon opening the box, leaving them cursing in despair as they must continue holding. The actual pissing scenes are edited in dual and triple angles, offering an immersive view of their release. Women who endure are measured for urine volume, with bladder distension and other physical responses recorded. In this volume, five women end up leaking, while two reach total surrender. Born from correspondence with fan A-san and continuously evolving through viewer feedback, this series powerfully stirs deep emotions among pissing fetishists. All seven performers appear with faces fully visible, delivering an authentic and intense experience.
