My best exhibitionist incident occurred at a nude swimming hole in Vermont. It was a series of waterfalls. My former girlfriend and I climbed to one of the upper pools. We were standing in about a foot of water and she was leaning against a boulder. I was fucking her from behind. Another couple climbed up and saw us. She wanted to turn around but he wanted to stay. He was clearly enjoying the show. She kept looking away and covering eyes but also peeking and giggling. I puled out and came on my girlfriend's back. It was so cool.
