Just recently I married a man who had a child. My stepdaughter, 心海ちゃん, being at that age, seemed like it would take time to become close. I thought I would be spending happy days in a happy family. Then one day 心海ちゃん started inviting her male school friends over and ordering them to attack me! I begged 心海ちゃん desperately for help, but she only watched me being raped with a smile and contempt. From that day on, the days of being gang-raped by my daughter's classmates began.
