I've never told anyone about this so here goes. I have a sister that's 2 years younger than me. When we were little we used to take our clothes of and fool around. I remember enjoying her body and vice versa. I think I was 6 or seven the first time I remember. I also remember my mom walking in, but I don't remember anything after that. This went on fairly often until we were about 12 and 14. I remember so many of the encounters. After the age of about 14 sometimes (though less often) my sister would try to initiate some type of sexual play. Before it was both of us doing the initiating. As we got older we would both feel a bit guilty afterward. I remember when I was in the 11th grade I had been away for the summer. When I arrived back home my sister kept staring at me, licking and biting her lips. I totally ignored her, but I was very turned on. My senior year of high school was the last time she made advances toward me. Early one morning she came into my room with spandex and an excercise bra on. I think she thought I was sleeping. She was acting like she was gathering laundry. As she was finishing our eyes lock and she seemed startled. When I got up later the laundry basket was right outside my bedroom door. I kinda think she was try to see my dick because I often woke up with it out of the fly of my underwear and erect. The following year my mom remarried and they left us at home for a honeymoon of coarse. Several things happened during that time they were gone but one night stands out as clear as yesterday. It was about 11 pm and I was already in bed. My sister got out of the shower and walked directly into my room without knocking. I wasn't asleep yet and she was only wearing a towel. She sat down on my bed and started talking about something very unimportant. It was obvious what she was doing. Anyway I didn't give in and she eventually left. A few hours later I heard a loud noise coming from the livingroom. As I went to see what it was she passed me and brushed up against me very seductively. She was wearing a small nightshirt and I was in my boxer shorts. Once again it was obvious what she wanted. I had girlfriends and she had boyfriends during this time period. We are both married (to other people) and have kids now. Part of my confession is the fact that I desperately wanted to go along with whatever would have been. I thought the whole idea of us together like that would have been a huge sexual relief. The guilt it would have brought us both is what held me back. Although I wish it would go away I still fantasize about her (especially about the night my senior year). I get along fine with her now, and I have a good wife that's also good in bed. I just wonder how common this type of thing is. Will the sexual thoughts of her ever go away? I also wonder if these thought are common in females after these types of experiences. Please don't judge me. All of this has its roots when we were very young. I don't remember being abused sexually as a child though my dad has been convicted twice of non aggravated sex offenses toward minors. The last one got him 5 years in prison. I'm just looking for some helpful ideas and opinions. Thanks.
