So I’m 16 and my mother had me when she was my age. She’s been through her fair share of men, but she’s only actually married men twice. The second man she married is my sister’s dad. I do remember everything in surprising detail. He would ask if i wanted to play hide and seek and I said yes because what kid doesn’t love hide and seek. He would hide in his bed and when I found him he’d insist on a different game. One that led to me being molested. He never penetrated me with his dick, but he did with his fingers and tongue. I was 7-9 while this was happening. It happened for two years. He even fingered me while his mother was in the room. I was young and didn’t understand. I told my mom but she didn’t believe me and kept asking if I was sure. I guess I finally gave up and just said no that we were wrestling with our clothes off. She never said anything else and my sister still sees her Dad regularly. Now my mom is dating a different guy. He likes to give me massages and will sometimes massage my ass and upper thighs, which makes me so uncomfortable but i don’t say anything. One time I was watching Grey’s Anatomy and they were talking about doing a surgery on a woman’s vag, I was wearing gym shorts and he then proceeded to run a finger up my vag and laugh like it was a joke. I went to my room. He tried to touch me in that area before and did it after, insisting he was just massaging. I don’t know what to do. I don’t want to tell my mom. I somehow convinced myself that this is my fault for having a dirty mind and thinking about sex a lot. Nobody knows. I’m scared to sit on the couch alone with him because I know that he’ll try and do that. I don’t even know if he realizes that what he’s doing is wrong. What do I do?
