I had sex with my sister when we were kids.

I am a 17 yo girl and when I was 3 my mom told me that I had a child sister and she was 1yo at that time. I was so happy and I wanted to hug and love her. My mom told me that it was normal for brothers an sisters have sex, so my sister an I had sex many times until I was 7 and she was 5. Our mom told us that it was normal and you can have sex with your siblings. My sister was very curious and wanted to try more things. I didn't want to do it anymore but my mom told me that I always have to let my sister do what she wants because she is my baby sister. I was afraid to tell anything because I thought that I was bad and I was doing something wrong and my mom told me that it's normal and that it was only a game. <br><br>I don't feel confortable with this and I don't want to have sex anymore and she is very sad because I don't let her anymore.
