Maya Natsushiro, a former dental hygienist now in her second year of marriage, is a tall, intelligent-looking beauty. She married a dentist from the clinic where she used to work and currently lives as a full-time housewife supporting her household. After marriage, her husband cut off their sexual relationship, citing work stress, leaving an emotional void that led her to begin a secret affair with a man she met through an extramarital dating site. Under her lover's strict training, her body gradually awakened to increasingly masochistic pleasures. Following his command, she decided to participate in an AV as part of an NTR (cuckold) experience. As a result, she gained the freedom to indulge in pleasure exactly as she desired.
