The 14th installment in the series created with our comrades. This is the fifth experiment in a series exploring the theme: "How long can a girl control her urge to pee?" This time, the girls start already holding it in, and the experiment allows them to urinate only a strictly limited amount—less than one cup—after being pushed to the point where they beg, "Please let me go to the toilet!" As a result, they don't fully relieve themselves, and their frustration and anxiety are vividly captured as they squirm uncomfortably. The timing of when urination is permitted gradually increases—10 seconds, 20 seconds, then 30 seconds—highlighting significant individual differences. The results: four successes, two failures, and one borderline case, all shown in raw detail. The challenge begins with the girls in a standing, squatting posture, and the footage captures a range of reactions: sharp, clean "Jo—Pita!" streams, painful endurance, collapsing mid-attempt, and even girls failing right from the start. A deeply endearing portrayal of girls holding their pee. Responding to strong fan demand, this experimental series returns with seven girls participating. The main feature includes scenes with visible faces.
