A housewife whose sex life with her husband has stalled and who has built up sexual frustration becomes obsessed with oil massage. After drinking a herbal drink laced with aphrodisiac, she feels a tingling sensation in her crotch in the shower room. Despite feeling shy towards the male therapist, every time his fingers roam and knead her body heated by the aphrodisiac, her oil-slicked body reacts sensitively as if electric currents are flowing through it. Unable to bear the desire for the erect penis of the therapist in front of her, she pleads. The moment she is penetrated, she can't help but arch her back in a shrimp-like spasm, coming and coming, her lewd body writhing in orgasm.
