I have done both in cars, both parked and while driving, also once got eaten out by a guy while I was driving.
I was a freshman in college and my boyfriend and I were parked in his old Corsica at the mall. It was a Saturday afternoon and very crowded. We parked towards the back, but there were still cars everywhere. So we slip into the backseat and makeout. I beg him to jerk off for me (guess I was a freaky freak then too) and he happily complies as I watch and kiss him...still fully clothed. Then all we hear is a "tap tap " loud on the window. I almost died. It was a police officer patrolling the lot and my lover was caught red handed, so to speak. Luckily he let us go after thoroughly scolding and embarassing us....but not before he put out our names and exactly what we were doing over his radio. We got back to his parents house and his aunt had called his mom after hearing about our failed rendevous on her scanner......
