Hitomi Honda, a married woman with an age difference from her husband, has found happiness like most people. However, her relationship with Masahiro Matsuda, the man who taught her the joy of being an M-woman, continues. One day, she learns that her husband has a terminal illness. Despite this news, Hitomi tries to maintain a positive attitude and hide the truth from him. Plagued by guilt, she finds solace in being violated by other men, losing herself in pleasure. When faced with her husband's decision to accept death without knowing the real her, Hitomi makes a bold move - she shows him a video of herself being trained as his slave.
