Matsumoto, a blonde schoolgirl who makes money by dating a sugar baby, visits a sexual therapy session at the suggestion of her partner. During the session, Matsumoto loses consciousness and wakes up to find her hands and feet bound. The man who appears before her completely ignores Matsumoto's protests and continues to stimulate her breasts and vagina with an electric current device. She jumps and trembles like crazy, and her whole body is violated, covered in goosebumps.
