When I was younger, my sister, two years older than me, and I got along really well. She would always flirt with me, and I really didn't mind. I did kind of like it. Then, she started having fun playing at being quite amorous with me, and I went along with it. Being daring and uninhbited, she talked me into being naked with her, and we started to play around and enjoy mutual mastubation. She thought it was great getting to do that with her brother. Well, I enjoyed it a lot too, and of course mom and dad never knew that we were being that intimate with each other.Anyway, fast forward to ten years later. My sister just got divorced from a rather rotten husband who no one in our family liked, and she moved back to town. Of course we started seeing each other, and she teasingly reminded me of the fun that we used to have together. I feel a little embarrassed about done that with my own sister, and have never told anyone. She isn't embarrassed about it at all, and says that she has really good memories of our being that close. I knew that she was starting to suggest that maybe the two of could have some more fun like that together now. I was reluctant, but I gave in, and my sister and I actually had intercourse. At the time, it was quite exciting and fun, although afterward I felt guilty about having enjoyed that with her. She says that I'm just taking it wrong, and that I shouldn't be so up tight. I suppose that maybe she's right. She has taken precations and is on the pill, and she is all for the two of us having an affair as brother and sister, which she finds very exciting. In a way I do too, only I just remain unsure if we should be having these intmate moments together. Our mom and dad still have no idea of just how close the two of us are, nor does anyone else. I don't know quite what to, and if anyone has been in a simular situation or has any advice, I would like to hear it and soon.
