It's easy to talk about it now that they are both dead. So is my step-mother, so I'm the last person still standing who had any part in it. I don't have to be concerned about hurting anybody's feelings or retraumatizing them. She told me directly that she enjoyed the sex, and I was an avid masturbator myself before that by age 10, so I didn't doubt her. Many girls are masturbators before 10, without being molested by anyone. It's just something they like, and they do it just for that reason. Some girls don't and their discovery of their sexual nature may happen many years later. That's in the range of normal human behavior. Sex really doesn't carry all the emotional baggage we experience, for young kids.
I didn't see her for several years after that, since our step-mother had a horrible unsympathetic jealous reaction and sent her into foster care. Effectively, mom blamed the victim! That's the start of my life-long disillusionment with my step-mother. But after he got out of prison, mom still divorced dad when my little sister was 7, just to get my little sister out of there. I left home at 17, and they immediately moved out. I suppose my presence in the house made my step-mother feel more secure about dad not molesting my little sister, but I never thought that was very smart myself.
I did interact with my sister later, when she attended the college my dad used to teach at. She had some therapy, and was doing well. Had normal relationships with boyfriends, and married a great fellow I just saw on Friday at their younger daughter's wedding. I believed what she had to say about it then and later as an adult. If some choose not to believe her, that says more about them than her. She was very well-centered and stabile as an adult, was a great wife and mother, and lived a peaceful and comfortable life. She was brilliant, too, and worked for the navy as a computer programmer before she married. Cancer took her much too soon, but she did get to see grandchildren of her older daughter.
