Neice

So my neice and I are closer in age than her mom/my step sister and I. We grew up together and used to do all the little touching and playing games with each other as we grew up. When I was 24M and she was 17F she came over to my house and told the family she was going to help me clean up my house. We sat in my hot tub and had some laughs about all the old fooling around and touching We did when we were younger. She then slid over to me and grabbed my cock. Told me she really wanted me to put it in her and make her cum. I knew it wasn't right, but 10 minutes later we were naked on the livingroom floor with my cock buried balls deep in her. She had like three orgasms and I then pulled out and sprayed her with my cum. She spent the rest of the weekend with me, but we didn't recreate the events of the first night and really didn't talk about it much, except to say that it really wasn't right. Years went by and she came back into town to visit family. She was married and i was going through a divorce. We went to dinner and had a few drinks and once again we ended up at my place. The sex was good and we both were spent, but again the feeling of it not being right just rolled over us. She left two days later and we didn't talk for a few months. Then she started texting and sending photos to me over the phone. Sorry for the long story but im still perplexed to this day. Was our childhood attraction just too much for us to ignore and move on and why do we still send pics to each other. No we don't live in Arkansas!
