I observed that she also seemed to have nice large breasts.We asked her over to our table and she was very feminine and told us through the course of ...ur talk that she was to have an operation in about two months that would make her fully female. As we spoke, she and Melissa hit it off and I could see that Melissa's hand had disappeeared and she was checking out her cock. I could also tell that Ashley was exploring Melissa's pussy.I kind of felt left out and asked Melissa to get us a couple. I too give a little extra bounce in my stride for her benefit.By the third mile we are both very sweaty. Sandy's top is almost transparent, her nipples clearly visible. We have come out of the grove of trees and are now in the middle of the tall grass meadow. There is still a mile and a half to go.Suddenly, Sandy reaches out and takes my hand. Smiling, she leads me into the tall grass about twenty-five yards from the path. Stopping, Sandy pulls her shirt off and then her shorts. I begin. I took her out behind the swim float in the lake and was easily able to insert underwater since she was well lubricated from who knows how many recent semen spurts. She loved getting laid in the woods, in the beach shelters, in the community shower with an audience even, and taking turns all night with me and Ed. A true love child.One last story about this saucy wench before I move on. I was looking for Brent at their tent but the door was zippered shut. I heard a noise inside so went around. Then she noticed the delivery van was still outside and the man was sitting in the cab on the phone, he could see straight into our living room were she was looking out of the window.At this point I decided to dare her to undo her robe and let him see a bit more, thinking she would say NO, but instead she told me that she would pretend to clean the window and as she did she placed the phone down put it on speaker so I could hear her and she could hear me, she proceeded to tell me what she was.
