First sex in a car...
1983 Chevy Blazer, out in 4wd land. It was buddies truck, and I forgot and left the "wrapper's" wrapper on the floor. A few weeks later we traded vehicles again (he needed my MPG car for work) he bitched... I left the condom wrapper on the dash this time.....just to piss him off.....
I still have the girl, 10 years, and 4 kids later (2 week old twins!) :D
