"Karin, Shizuka. If we report this pervert, our family will fall apart?" One day, our mother decided to remarry. Her new husband's father gave off a creepy vibe. He looked at us sisters with lecherous eyes. Because of our mother, he didn't try anything. The worst kind of life. One day, my father who always takes the same train started touching my butt and crotch. Taking advantage of when my mother wasn't looking, we were treated however he wanted, and although we felt like crying, our lower bodies were inexplicably tingling and convulsing. My sister and I started going crazy after being secretly raped by our hated stepfather on a train… That pervert, he might not stop…
