Office lady Mai, worn out from her hectic daily routine, visits a massage parlor seeking relaxation for her mind and body. Opening up about her work stress in the soothing atmosphere of her first oil massage, she begins to feel a mix of embarrassment and arousal as the therapist's hands move toward her chest. The masseur’s smooth, skillful touch gradually draws her in. Softly whispering, "It's been so long since a man has touched me..." her consciousness starts to waver. Sensing her response, the therapist grows bolder in his techniques. Unable to resist any longer, she pleads, "I'll keep it a secret... just a little... could you put it in?" Surprised but yielding to her request, the masseur gives in. What began as a healing session transforms into an illicit, pleasure-filled encounter.
