Shirt on, no pants
I have only rarely driven in the total buff . . . I guess since I got over 40 and my gut wasn't as flat as it once was . . . I prefer having at least a tee-shirt on. But anytime I'm wearing nothing but a pair of shorts (which is everyday in the summer) and I get out on these back Colorado county roads . . . I drop my shorts down, roll the windows down .. . and "feel the breeze" ;-)
I went to take some nude photos in the other side of the Dales today, about an hour and a half's drive away. The wind and rain didn't keep all the walkers away so I wore something easy to take off and pull on - a pair of shorts and a zip-up fleece (and boots, nothing else). I got caught at the end of one photo shoot.
Anyhow I had to take off all my wet clothes as I got back in the car. I had a spare top but nothing else. So I drove home bottomless - through two towns a small city and countless villages. When I got home I had to unpack the car, bottomless, before I could put it away.
Then I took my top off and spent the afternoon naked, doing the ironing.
It's quite common to find me behind the wheel wearing nothing but a shirt, i do it all year round and love having my bare arse on the seat and my cock hanging free, in the summer months on a hot day i'll drive nude, it's not uncommon to see a topless man at the wheel then, so i guess no one gives it a second thought that a topless driver might just be nude.
