Ever see the movie Parenthood? Another Steve Martin movie...has a great scene where he and Mary Steenburgen have not so safe sex while driving.
Sham.
P.S. personally i haven't done it in any of the three 
lol
BJ while driving - yes - but it was some time ago. Can be dangerous if you've got a highly skilled bj artist doing the giving! But I'd do it again in a heart beat now that I have a big safe truck to ride in
In non moving cars - many many times (ahh to be young again!). Got good at it back in college too, her hands in the back seat, one leg on each front seat, seats all the way back and down, and you've got some good doggie action on wheels In a limo is a quest that is on my short list of things to do.
Train - Haven't been on a train since I was 6 years old. If the subway counts as a train, then I got some HJ action on the subway once. Too bad I was drunk and whiskey dick set in before I could finish.
Planes - never but I'm ready and willing. It honestly doesn't even look like much fun (too close quarters), but for the bragging rights alone its worth it.
Helicopter - if anyone has pulled this off, your my new hero.
And to add one more motorized twist..............
Moped - I got my first hj/bj while on my moped at age 15. Had a lovely on the back and her hands casually moved from my waist to my groin, almost dropped the bike so we had to stop at which point she dropped to her knees. Who said mopeds aren't cool !!
Call me naive, but it never occured to me to do it there. We were on a trans-Pacific flight, sitting in the business class section, which was upstairs (is that a 747?), so it was separate from the coach and first-class sections. When everyone went to sleep, we did it right in our seats! If anyone was awake and knew what we were up to, they didn't say a word. Later, when I heard of the Mile-High Club and how people did it in the restrooms, I was surprised. It's so cramped and dirty in there!
Love your moped story!
