The wife, caught by the repairman she had called to fix the kitchen while engaging in indecent acts with her casual lover, gives in to him just once. Unlike her husband or her lover, the repairman's passionate sex captivates her. She tries to cut ties with her casual partner, but he keeps intruding with relentless harassment. Eventually, the repairman witnesses her again in a compromising situation, and she is drawn into a game involving both men. Her aroused body can no longer be restrained, and even when her husband returns home, she loses control and desperately begs for unprotected sex.
