Tsubasa, who married a husband much older than herself, obtained ordinary happiness. However, her relationship with the man Matsuda, who taught her the pleasures of being an M woman, continued. Just then, she was informed of her husband's remaining lifespan at the hospital. Tsubasa hid this from her husband and acted cheerfully... but she indulged in the pleasure of being ravaged by another man while harboring guilt. Her beloved is about to give up on 'life' without knowing the true her. The answer Tsubasa came up with was to show her husband the sight of herself being trained as a slave.
