One day, the husband's older brother comes to stay over and rapes his sexually frustrated wife. Excited by her amazing body, the older brother penetrates his wife, who resists. Her body responds, and she convulses next to her husband, climaxing violently and muffling her voice. From that night on, the older brother and wife make love in secret. They are burning with passion in their forbidden sexual intercourse.
