Just the other day, I married a man who had a child from a previous relationship, and we had just begun building a new life together. His daughter, Miwa, seemed to accept me warmly, and we were enjoying a happy life. However, everything changed when Miwa invited some of her classmates over to our home. The boys suddenly turned on me, assaulting me one after another. Desperate, I begged Miwa for help—but instead of aiding me, she looked on with a cold smirk, mocking me with a look of contempt. Since that day, I've become a target for her classmates, and my daily life has turned into a relentless gangbang.
