I go hiking in some Adidas shorts and no underwear. I piss into a bottle, taste some, and pour it slowly over my shorts. As the fabric gets shiny with piss, I enjoy letting my cock pulse under it as it clings to my skin. When I get to the top of the mountain, I piss in the bottle again and pour it down my shirt, and all over my throbbing cock hanging out. Then, I jerk off and cum all over the rocks.
