Sayaka Ichinose visits her boyfriend's apartment, excited and full of anticipation for the beginning of a new relationship. However, her boyfriend reveals unexpected desires—he shows little interest in conventional sex and instead asks to watch her defecate. Though shocked and confused, Sayaka agrees, wanting to fulfill his strong wishes. Suffering from constipation, she visits a hospital where she meets a nurse who shares this unusual fetish. Under the guise of medical treatment, the nurse makes her defecate naturally in front of her. Later, she undergoes enemas and is forced to release large amounts of enema waste while still wearing her underwear. This documentary-style production captures detailed scenes of natural defecation and enema-induced bowel movements.
