After being asked by my bedridden mentor to investigate the current lives of four former female students, I began visiting them one by one. I discovered that each woman was dissatisfied with her married life and had been secretly involved with men other than their husbands. Despite feelings of guilt and moral conflict, I couldn't resist my own desires and gradually became intimately involved with them. As I uncovered the secrets of their hidden lives, I began sharing my own sexual experiences, deepening my inner turmoil and emotional struggle.
