You feel the call of nature

Along the way you have drunk an entire 1 liter of water without realizing it until you feel the sudden and urgent urge to urinate. You know you must be the only person on this trail, because a woman a little older than you has crossed your path in the opposite direction - she probably owns that other car in the parking lot. But you feel insecure about dropping your pants in the middle of the trail, since someone might be coming the same way you did.

So you step off the trail for a few meters until you find a more "private" spot behind a huge tree trunk. You look all around without seeing anyone and hearing anything but the sounds of nature, so you pull your pants up to your ankles and squat down next to one of the tree roots. It takes a while for your bladder to release its urine, and meanwhile you feel the breeze gently touch your bare privates. You feel a slight arousal, but you push the erotic thought away and try to concentrate on what you need to do.

The strong, warm stream of urine makes your body shudder, and your pubic hair would be standing on end if you had any to cover your pink pussy lips. It feels so good that you think for a moment that it would be very nice to continue on the trail without any clothes covering your body. But as soon as you finish urinating, the thought goes away too, and reason begins to tell you that you are in an unknown environment to do something so daring. And besides, you are only a home exhibitionist, and even then you only go without clothes when all the window curtains are closed.

Convinced that all that is left for you to do is to walk for perhaps another mile and then return to the car, you stand up and quickly pull your pants up. Then your eyes widen and your body petrifies.
