Hidden camera footage from an actual high-end massage parlor located in Aoyama. A special session where the therapist demonstrates the correct method of masturbation to stimulate female hormone secretion essential for beauty and health. First is a slimming-focused shaved college student. Under the therapist's guidance, she learns proper self-pleasure techniques while mutually stimulating erogenous acupoints on each other's genitals, writhing in pleasure. Second is a female cram school teacher learning how to touch her genitals. Following the therapist's finger movements, she explores acupoints inside her vagina using her own fingers, suppressing moans while building intense arousal until she reaches climax. Third is a petite 30-year-old woman who works at a funeral home. While receiving self-care instruction, they passionately grope each other's breasts and stimulate internal genital acupoints, realistically captured as they pursue pleasure with wet sounds filling the room.
