The shame and guilt a married woman feels. To fulfill her husband's cuckolding desire, she accepts a request from the organizer of a swinging club. Her partner is an M-friend, 24 years old, married for three years, no children. A serious wife chooses to accept another man in order to understand her husband. Though she tries to resist, her sensitive body reacts intensely, writhing her hips and moaning during foreplay. As excitement builds, she pleads, "Please put it inside me." Afterwards, when her heated body is groped after a bath, she writhes again. She climaxes repeatedly, ruined by toys and pounded by a cock.
