Nishihara Misuzu, 42, a sheltered housewife born and raised in a prestigious Saitama family. Raised under strict parents, she had no relationships outside her marriage and no sexual experience beyond her husband—truly a woman of impeccable background. Everything changed when she met other mothers at her son's school PTA meetings. Shocked to learn many married women still had boyfriends, she was even teased for being outdated. From that moment on, her long-suppressed desires began to awaken, leading her to make a bold decision. This debut work captures her first time in front of the camera, unleashing passions she could no longer contain.
