“Take me from behind!” She suddenly demands. I pull my long thick shaft out and sit back watching as the girl of my dreams rolls over positionin... herself on all fours in front of me. I admire her gorgeous figure as she moves in front of me, particularly her heavy breasts and the way they now hang down almost touching the bed, the nipples still hard. With her full gorgeous bum cheeks in the air I part her thighs to reveal the enflamed lips of her wet pussy. Turning her head and looking over. This isn’t bad! Callie gives me a thumbs up, Lisa’s nowhere in sight, but this guy seems to like me! The music speeds back up, but we’re getting to know each other and I’m ok with it. It seems like the evening goes by too quickly.‘Um, looks like they’re closing.’ he says with a rueful look. I see Callie kisses the guy goodbye, so she’s going back to the dorm, which is what I need.‘Uh yeah, um….do uh, you, um….’ I mumble.‘Do I want to see you again?’ he says with a grin. ‘Yes, I do, would you be. She likes to tell me all about how much of a hand job and blow job princess she was in college. It gets me hot when she tells me about it. She also likes to tell me about the 2 girls that she would fuck around with in College. She knows that my fantasies are twisted. But I am seriously turned on by her sexuality.I’ll just say that we have a very active, twisted sex life. Enough background. Now back to the main point.Our night at the movie would prove no exception.When the movie started I felt. Now we were like an old married couple humping away with abandon on top of her bed but doing our best to keep as quiet as possible to avoid discovery.I never considered our "fooling around" to be in any way incest because I had never laid sight on my step-sister Nicole until she moved into our house with her father who was not my new step-father and head of the household. He was a cool guy who minded his own business when it came to me and didn't seem to care about disciplining his wayward.
