A 45-year-old married woman confesses her long-suppressed desire for submission. She has always longed for SM, wanting to be tied up and tormented, but that wish was never fulfilled, and she has reached this age. Although she has built an ordinary yet happy family, she could no longer keep that desire sealed away. Dear enthusiasts, please despise this wretched and sinful masochist. That is the punishment this shameless middle-aged woman, who has betrayed her family, deserves.
