Mine happened about a month ago. I was super freaking horny and the guy I'd just started dating was, too, so after work we met up and drove out to what we thought was a dirt road. We were in the back seat, things were so fucking hot, I was like two seconds away from orgasming (from the best head I'd ever had in my life). Suddenly there were headlights! We were on some farmer's driveway. Next thing i knew, we were going 120 down the road, while i was trying to get dressed in the back seat. Neither of us came, but it was still the most exciting sex I've ever had!
