When I was about 7, my older sister
sarah started making strange sounds in her bed. We shared a room at the time. I was young and had no idea what was going on, so of course I asked, right then and there. Sarah explained what she was doing, and that it felt good and tlaked to me about her sex ed. classes. Explained ************ to me, for both males and females. She took it so far as to perform mutual ************ with me within a couple of weeks. We moved on, based on ****** we'd seen on the late night cinemax channels. Whish wasn't much at the time, but enough to see what the basics of sex were. It progressed to oral and finally intercourse. We never felt ashamed and we continued for close to 5 years, until I was old enough to actually be able to get her pregnant. Because of this my other older sister Tara ended up having sex with me during that same 5 years and Tara continued until I was 15 years old, and not merely 12. Tara and I stopped after she had a pregnancy scare and I was so afraid to have sex with her again that I put a stop to it. I don't really regret what we did, any of us. In fact it brought us closer together. I love my older sisters very much. I wonder though, what possessed us to have sex when we found out it was wrong? Why did we do that to ourselves? Even today we let things go over boundaries that should always be there. We don't mind showering together, or seeing each other naked and we even still kiss as lovers when we are up late at night spending quality time together. We are careful not to do any of this when other people are around, but the three of us, despite having our own lives, just seem to have this common pact that it's ok to cross these lines. What is wrong with us?
