Jun, a full-time housewife, visits a beauty salon introduced to her by her husband as a reward, but it turns out to be a shady salon run by middle-aged male therapists who exploit women's bodies. Using oil laced with aphrodisiacs, Jun is massaged with a sticky, risky massage to make her sweat and her sexual senses are stimulated. Jun begs to stop, but her body cannot resist the pleasure and she gradually becomes aroused. She convulses and climaxes to the point of wetting herself, and squirts repeatedly with an ahegao face. Jun's body is developed into a perverted body with erogenous zones all over her body. She sneaks away from her husband's eyes and repeatedly visits the salon, becoming a slutty wife who exposes her sexual desires and squirts as she climaxes, letting out obscene moans.
