Four married women seek discipline. Initially reluctant, they now crave it. 01 Wakana (30) feels dissatisfied due to her husband's long-term work assignment away from home, satisfying her desires through an affair. Despite being provoked with humiliation, she steps into the world of abnormal pleasure. 02 Shiina (35) is discontent with her older husband and chooses infidelity with her prime feminine body. Undergoing perverted training, she falls deeper into ecstasy. 03 Kana (46) dedicates herself to her family but receives no affection from her husband. Shocked by an SM website, she meets a man through social media who begins to train her, making it impossible to return to normal sex or life. 04 Chika (34) has emotional instability and lacks love from her husband, spending a night with a stranger. Discovering the joy of being desired, she begins accepting anything asked of her. One day, visiting the man's house, she encounters an astonishing discipline session waiting for her.
