A male massage therapist who has come to the house on a business trip gives an oil massage to a young wife of a couple. Recently, the couple has not been intimate, and the honest young wife, who has never cheated, is in a state of sexual frustration. Her body, already sensitive to regular treatments, becomes completely aroused with more daring techniques. She begs for sex, asking for his penis, and desperately suppresses her moans to avoid being discovered, reaching orgasm repeatedly. In her own home, with her husband nearby, the once chaste young wife transforms into a depraved woman, taking another man's penis deeply into her mouth and enjoying it to the fullest.
