CRSD-004 — The Demonic Family ~An Innocent Step-Sister Is A Little Devil Who Captivates Men~

After my mother died, my family became strange. My sister and my father had a relationship. My new mother and brother came along, and a subtle distortion occurred in the family. My sister immediately got a taste of my brother, and my parents had sex with him every night. My sister was jealous of my father and attacked me. I was happy, even if it was just to get back at me. But I never thought it would turn out like that.
