Cheating Babe Fucked on Backseat

This petite blonde got into the backseat today and told me "just drive." I thought it was strange, but I've had more bizarre requests, so I went along with it. She asked me if I was married, and said she was wondering because I turned her on. I thought it was a prank, but when she spread her legs, took off her panties, and played with her tits, I knew she was serious. She said she had a boyfriend, and this was a fetish they shared, her hooking up with strangers. She begged me to pull over so she could suck me cock. I fucked her tight, wet pussy in the backseat of the car and made her climax, then I pulled out to cum on her.
