Jag räddar min styvsyrran ur fängelset och hon låter mig knulla - Serena Sterling

My step sis, Serena, called me while I was at home one day. She called me from a prison number and asked me to bail her out. I was pissed and she definitely owed me. I drove to go and pick her up and sure enough it wasn't a prank; she had a prison uniform on. I drove us home and I called her to my room shortly after. I told her we needed to talk about what she owed me and I wasn't sure if I should tell her. She asked me to tell her and she said it was fine so I confessed that I wanted to fuck her. She was definitely against it at first but I did her a favor so she said she would do one for me. We ended up fucking in various positions until I came all over her face.
