This is relatively nasty......please read my PM
And Chelsea - make sure you're on a fairly straight road, with little traffic. Highways can be good for this, as long as your SO doesn't drive like a maniac. But so can deserted back roads. Then, when you think it's safe... just start touching him. Let him know you're in the mood, and make sure that he is, then off with the pants. Initiating it isn't any different than any other time, you just need to know the time and place.
This however....is sound advice
Can anyone say "road trip?"
