One day, when I came home, I saw a strange woman. Dad introduced her as his lover, but I couldn't concentrate on listening to anything. No matter what I thought, she was too beautiful, not worthy of my father. As time went on, that woman became my stepmother, and we began living together under the same roof. Because I watched too much, I gradually realized that I saw her as a woman, not just a stepmother, so I often showed a cold, curt attitude. I want her... want to take over that body. The lust in me grew bigger and bigger, to the point where I couldn't control it anymore.
