My mother died of cancer when I was 16. Within a year, Dad remarried. Dad was 48 and Sarah was 32. I was not happy because I was really close to my mother and I missed her. Sarah tried almost everything to win me over. I came home early because we only had a half day of school and found Sarah fucking some dude I had never seen before. The guy quickly dressed and was gone. Sarah asked me if there was anything I wanted not to tell dad. I half jokingly said I wanted to finish what the dude started. I promised not to tell dad if I could fuck her. She helped me undress and I was soon naked, but couldn't get a hard-on. Sarah grabbed my cock and sucked it hard so I could fuck her. Dad was a TV news anchor so he was gone from about 4:30 to midnight every week day. Sarah and I had the apartment to ourselves and we had sex 2 or 3 times each week. We sucked and sucked each other and Sarah introduced me to anal sex. She and her 1st husband divorced because he knew she was fucking other men. It's amazing that she thinks of sex almost forgetting every thing else when she is in the mood which is often. I am now a senior in college, but I get home almost every weekend. We must be a lot more discreet because Dad is also home. We seem to be able to get together in spite of Dad being home. Sarah and I have non stop sex whenever I am on fall break, spring break, holidays between semesters and summer vacation. Last summer she wanted to have a threesome with me and another guy, but I surprised myself by saying "no way". I'm willing to share her with Dad, but nobody else. Keith Stringer
