Under the rule that women must hold their urine until the timer goes off, allowing them to pee only when time is up, this project captures their intense struggle on hidden camera. Starting with strong urges, each woman displays unique and individual ways of enduring. When the first timer sounds, signaling they can finally relieve themselves, a second timer unexpectedly appears (+12 minutes), unknown to them. The moment they open the box and discover the extension is the highlight, revealing their shock and disbelief. They continue holding desperately, sharing personal stories about urination, pressing their hands between their legs, squirming their hips and legs, showing raw and realistic strain. Relief is short-lived—upon discovering the extended time, they react in disbelief and frustration, yet still push through. Those who endure are measured for urine volume, and their bladder distension is recorded. In this installment, four women ended up wetting themselves. [Voluptuous lower-body girl Honoka] managed the first timer while crouching uncomfortably, but quickly lost control, yellowish urine dripping steadily from her large ass. [Cool, laid-back girl Nanami] maintained a composed stance to beat the first timer, but stood dazed upon seeing the extension, then suddenly leaked while still standing. [Beautiful-legged girl Mika] used clever, energy-saving techniques to endure efficiently and successfully completed the challenge. Though visibly upset by the extended time trap, she had accumulated a substantial 800cc. [Innocent girl Miyu], already writhing in urgency at the start, endured in a tight-kneed seated position but eventually let out a sharp cry as she lost control. [Beautiful girl Marina] began the challenge already clutching her crotch, clearly at her limit. She lasted only about ten minutes before reaching her breaking point while standing, gripping her thighs. (Haisetsuya) ※ Facial exposure in main video
