I still can not believe my girl was cheating on me. I am glad Rubi told me about it. She seemed like a nice girl and did not want me to get played. She wanted to help me get back at her sister,  so she offered herself up for some pay back. I knew Rubi was the younger sister,  but I was not sure how young. She re insured me that she was 18. I was all for it then. I picked her up and slid my cock right in her tight wet pussy. She was loving it. I got to do things with her that the cheating sister does not like to do.
