The car (on and in), the beach, elevator, outside a bar, and the craziest was the middle divider on a busy highway. When I was a much younger guy I dated a nymph who had me pull over the car- I thought she was sick- she pulled down her shorts and had me take her from behind...I can't tell you how many honks I heard...unreal.

Some of the same places as most. The ones that stand out were in public or that type of thing. Full on blowjob in the movies a couple years ago, hood of my jeep, in a small boat out in a lake. On a waterfall, a resort hot tub at Keystone,Co. In a bar with people around. Road head. I even had my root cleaned by another guys slut in the Silver Bullet Saloon while Clint Black was in there when he first started out.
