Risk=reward
Love being completely naked in, the car especially going to and from beach. Folly Beach here in Charleston SC is a exhibitionist heaven. Hot southern girls and mature woman walking on side of road in hot , bikinis driving up next to * them completely naked and they haven't a clue that this hot naked man with a raging hard on all covered in oil is not ,3 feet away from them. The risk gives me head high that's so addictive. I drive naked as often as possible.
I agree risk=reward. But in my case not in a sexual way. I just get a buzz from it, no erection. It's especially great driving for hours with all my clothes in the boot (trunk) or otherwise out of reach. I do ensure I can get out of my car naked at my destination, fill up with fuel and carry some lunch, a drink and something to pee in (I did say driving for hours). I have pulled into a busy car park for my lunch, staying naked and surrounded by people getting in and out of their cars. Then there are the slow journeys through town centres or stuck in heavy traffic alongside a high vehicle or amongst pedestrians.
