When we were about twelve, one of my best girlfriends (there were three of us at the time) suggested we go swimming. It was a hot, humid day, but we didn't have our bathing suits with us. Since we were alone, and the water did look pretty inviting, she said we should just swim in our undies. So we ******** down to our bras and panties. When we were that far, my other friend said we should take those off too. Since no one else was around, we took our underwear off too, and enjoyed the feeling of being completely naked outdoors. There was nothing sexual about it, but it was fun. From then on, we did it whenever we thought we could get away with it. To this day, I love the feeling of being being naked outdoors.
