21-year-old college student Yua, a member of her university's volleyball team, visits a sports massage parlor for routine injury prevention therapy. As the massage therapist works on her toned, athletic body, she gradually begins to feel unexpected arousal. The sensation of his hands tracing her curves becomes too much to ignore. Telling him, "I won't interfere with your work," she starts touching herself over her clothes, her body trembling with desire. The intimate warmth overwhelms her, and she progresses to full masturbation. Unable to resist her bold advances, the therapist gives in to her seduction, ultimately having sex with her. The sexual appetite of this athletic college girl proves to be far deeper and stronger than anyone could imagine.
