You find yourself walking along a trail in a secluded area of a mountain park, you haven't seen a soul for maybe an hour and the temperature feels like it's 90°. You want to abandon your clothes and get a little closer to nature - so you do, and the next thing you know nature has taken it's course, and you've got one big righteous hard-on. Man, it sure feels good walking around like this, bare-ass naked with your hard cock swaying in front of you. It would be perfect if some young, well-built cock sucking dude would appear on the trail right now...
