DASS-523 A dispatched masseuse stimulates a wife too much, leading to cuckolding, Nami Kuroki

Nami, a young wife, has a good relationship with her husband and tries to conceive with him at night. One day she hurts her back doing dishes, and at his suggestion hires a massage therapist. The therapist stimulates her sensitive spots, and although she feels guilty, she looks forward to the next session. After several visits, she can no longer orgasm with her husband, and when the therapist asks if she wants to continue after the timer, she nods.
