I have to pee and there is no toilet in site. I'm in the middle of the woods on a hike to a swimming hole. I have to pee NOW! Good thing this is a secluded place, I drop my pants and bikini bottoms and pop a squat unloading my bladder and making a puddle. Then I find my bladder full again after a swim, I take off my bikini bottoms and pee right on the beach, its quite a messy fountain this time. I actually enjoy peeing outdoors.
