- Satomi was handcuffed by her homeroom teacher Sawada when she was in school, and since then, she has been called after school and continued to receive sexual training. Ten years after graduating, she was happily married as a young wife, but one day she was stopped by Sawada, who happened to be passing by, and was forcibly brought home. From then on, persistent SM training like a snake begins--Satomi was tormented by disgust and guilt, but she fainted in agony with the joy of a masochist female who had forgotten, and fell into the double life of an M guy who went to her husband's rich SEX.
