Mayuri Nakamura, a busty female college student, visits a massage parlor to relieve her stiff shoulders. As the treatment progresses, her body gradually relaxes, and the therapist's hands begin moving toward her intimate areas. Though slightly hesitant at first, her entire body has become highly sensitive from the massage, drawing her into a special sexual course. With her large G-cup breasts swaying, she experiences vibrant, energetic sex play—awaiting her is a rocket-like rush of intense pleasure.
