Ritsuko Tonono is a housewife. With her husband and son busy at work, she often feels lonely in her daily life. One day, she came across a visiting massage service. The therapist introduced himself as Ando, and lured in by his sales pitch and the offer of a free first session, she decided to give it a try. However, the service was not what she expected. The massage went beyond simple relaxation—her breasts were carefully kneaded, her sensitive nipples stimulated, and before long, she found herself developing a deep, intimate relationship with Ando. Seeking relief from the isolation of her routine, this was her way of taking the first step.
