In this work, sisters dressed in suits are forced into a situation where they must sit on a ball, ultimately leading them to wet themselves. As they talk openly about their past experiences with urination—whether they've ever wet the bed or leaked urine—their growing need to use the toilet is emphasized. When they plead to go to the bathroom, their requests are casually dismissed as "hard to believe," ignored deliberately, causing their urgency to mount and composure to break down. Eventually, they are made to sit on the ball with their hands tied behind their backs, the ball pressing firmly against their crotch, squirming as they struggle to hold it in. Some even begin to find pleasure in the act of enduring, which is depicted in detail. Against the backdrop of the Excretion Society's theme, the physical and psychological transformations of these women are portrayed with striking realism.
