Instructor Cheats with Hot Student

My colleague asked me if I could replace him today for Lady Gang's final lesson in the Mean Orange Machine. The lesson started innocently enough, but Lady kept mentioning how nervous she was, and this reflected in her driving. She performed poorly, and I told her she would need more lessons before taking her test. She freaked out and asked if we could make a deal. I told her that I was married, but when she showed me her big tits, I forgot all about that. We made out and she stroked my cock, then I walked around to the driver's side to pull off her tights and lick her ass and pussy. I fucked her wet pussy all over the car, then she finished the job and made me cum in her mouth!
