The act of defecating while fully clothed—known as accidental soiling or pantypooping—fills Suzuka with a strange sexual excitement born from shame, humiliation, and discomfort. She has a strong desire to record and document these experiences on camera. In the privacy of her room, she takes on the challenge of intentionally losing bowel control. First, wearing a pink swimsuit, she begins with an enema using an irrigator. The visual of brown feces accumulating in the crotch of her swimsuit is intensely stimulating. She then pleasures herself through masturbation, touching her soiled genitals over the stained fabric. Next, she tries something new: wearing a cloth diaper for the first time. After administering another enema, she struggles to endure the mounting urge to defecate while putting on the unfamiliar diaper. The sensation of her feces filling and expanding the diaper, along with the intense battle against her own bodily urges, creates overwhelming physical and psychological tension.
