It is quite the experience the first time you witness it, isn't it?
Growing up as kids in the rural town of West Greenwich, my friends and I spent hours skinny dipping in various swimming holes in the woods where we lived, but never in mixed company. (Unless it was just my sister and me)
The summer between my sophmore and senior years of high school (1976), I discovered Carr's pond in Rhode Island. It was a fairly big but secluded pond out in the woods, with water so crystal-clear, that it was actually used as a backup drinking water reservoir for the town of Coventry. Swimming was officially prohibited, of course, but unofficially, many free spirits (male and female) used to shed their clothes and skinny dip there. The only penalty for getting caught skinny dipping there, was to get chased out by the police or the DEP. The swimmers didn't allow gawkers, which were promptly chased away, but they welcomed anyone who wanted to get naked and swim or lay out in the sun.
The first time I went there, I didn't know about the skinny dippers, though. I went there to fish. The sight of guys swimming naked didn't surprise me...I was used to that, but the sight of nude women playing around in the water and laying out in the sun, sure did. I couldn't help but do some gawking of my own! I saw more T&A that day than I'd ever seen in my life!
Humorous story about that day:
I decided to keep my distance and try to get some fishing done a few hundred yards down the shoreline, but the idea of skinny dipping got to me and I soon shed my clothes and jumped in!
I swam around for a short time before I spied a large iron pipe that ran from a pump house on shore to the middle of the pond. Thinking that would be a good place to sit alone and soak up some sun, I swam about 50 yards straight out to it. I swear to you that I saw no one on the pipe at all when I started swimming for it, so as I approached it, I dipped beneath the surface to swim underwater for the last 20 feet or so. I reached the sandy bottom, swam along it until I saw a concrete support for the pipe and then arched back up for the silvery surface. Unfortunately, at the same time I reached the pipe, I saw several sets of legs dangling in the water! I had no idea where they had come from or whether they were male or female, but I was out of breath and had no chioce but to pick a spot in the tangle of legs and surface. I found a spot that offered some space and broke the surface. I was hoping that the space meant I was surfacing between two people but no, I surfaced with my face between the spread thighs of a twenty-something year old girl, her full, bushy pussy not more than six inches from my nose! I sputtered and choked, swallowed at least a gallon of pond water and tried to back out while also trying to appologize. My momentum had carried my legs under the pipe so I was on my back at this point and the only way to move away was to place my hands on her thighs and push myself away. All the while, she just sat there, looking down and smirking at me. Her boyfriend, who was sitting beside her, was laughing so hard at me that he was having just as hard a time breathing as I was! Fortunately for me, the couple found the whole situation quite funny and invited me to sit with them and later introduced me to some of their friends. I soon became a regular at Carr's Pond and spent most of that summer and the next one as well, hanging (literally!) with my new friends, naked as the day we were born.
