Konatsu, who is out of shape in the track and field club, receives a massage treatment at a sports esthetic salon to recover her exhausted body. However, the one who appeared was a malicious super-endurance shiatsu therapist who targets young women's bodies... A malicious coach who attacks her developed big-breasted sensitive body with an aphrodisiac inserted by despicable means. Increasing her sensitivity with sexual harassment treatment and making her nipples twitch and cum like crazy. Intense piston thrusting into her big ass, which is slick and shiny with aphrodisiac oil! Konatsu, who fell into cum training, neglecting practice. A climax sex massage with a hemp-like pursuit piston that makes her nipples stand on end and makes her cum like crazy while covered in sweat.
