I heard some voices from the bedroom and decided to sneak in to check what’s going on. When I reached the doorway I saw my stepsister was getting fucked hard by her boyfriend. She seemed to enjoy that but I already knew I could fuck her so much better.
On the next day we were chilling in my room with stepsis and all sudden she started to help her self. What a strange little slut she is! Then something really weird happened. She came next to me and said that “I am gonna check if you have a boner”
I asked why the hell she would do that? She simply responded that if I have a boner I gotta fuck her. Well, I had been watching her rubbing her pussy for like 15 mins so how could I not have a boner?
Things went forward fast from that point. She started to suck my hard cock and it would not take long until my hard cock was inside my stepsisters pussy.
