I've driven my convertible with the top down when I was nude dozens of times. Riding a motorcycle with only chaps and boots so that your ass, nuts and cock are exposed to the breeze kicks that up a notch. I'd like to be simarily attired and ride with you on your buddy seat and give you a hand job as we go along.
You can't beat the feel of nuts hangin' off the seat blowing in the breeze!
