Szorstkie ruchanie z przyrodnią siostrą najlepszego przyjaciela, gdy nie było go w domu

I went to visit my best friend and he asked him to wait while he went to the store. I thought I was home alone, but suddenly his stepsister came out to me, we started talking and she was clearly trying to hint to me that she liked me. She called me to her room, supposedly to help her with something, but what was my surprise when she came out to me in a transparent bodysuit and high heels. I couldn't resist and fucked her hard while my best friend was away.
