We laid there and just wanted to catch our breath for I just had the best fuck and the first of my life. I fell in love with Mark that day and want him to fuck me all the time. We kept fuckin and it got better and more hotter then ever. Mark would call me and we would have phone sex. I would learn how to fuck and everthing he wanted me to do with him. He video tape him fuckin my sister when she was 4 months pregent. We watch as he fuck me and I suck his cock. Mark told me about his pass and the sex with his sister. I was shocked and told me that they still fuck. I seen his sister in a different way now and when I would stop by my sisters house she would tell me that he was over his sister house to help her with something. I know what they where doing. I thoght about him night night and about his sex life and what he was doing to me. One day we where fuckin and he called me his sister and that really shocked me. Then it got different I came over one day and he made me wear his sisters bra and panties. I did and he fuck me so good that I must have cum about 3 time.
