My sister and I started having s** when we were young. We watched what our parents did and figured it out from there. I was 12, she was 10. As kids we often got our friends involved in the real game of playing doctor but I got jealous of the other boys touching my sister and her friends that I ran them all off and had all the girls for me. 20 years later my lovely sister has two great kids and a decent man for a husband. She is happy in her life and especially when Bill and I use her for our adult time alone.
