Bladder Observation 2: Limit Standing Piss Edition, Excretion Experiment Observation Series 11 Who's the JAV actress in this video? Amateur? Name revealed!

A woman's body naturally expresses beauty through its curves, and one of the most striking aspects is the swollen lower abdomen when holding in urine. When suppressing the urge to pee, the belly bulges in an extraordinary way, creating a captivating sight. While these girls surely wish to relieve themselves as soon as possible, this work deliberately denies them that release, instead focusing entirely on the theme of endurance. The goal is a highly intriguing scientific observation: to study exactly how the bladder contracts during urination. With this purpose, the girls are instructed to stand in a public urination posture and hold their urine until they involuntarily leak. Throughout, they are asked questions about toilet habits and excretion. Even more cruelly, they are made to press down on their own full bladders to demonstrate their reactions. Employing four cameras, the entire process is meticulously recorded with exceptional attention to detail. The moment they finally reach their limit, the act of standing while pissing is fully captured on camera. Featuring the Female Excretion Sect's most stunning beauties, this video includes schoolgirls (JK), women in business suits, slender types, slightly plump figures, and extremely thin women—offering a wide range of body types. A uniquely fascinating work that combines practical observation with visual appeal. (Hakaiya) ※ Facial exposure in main video
