I knew the beach Lisa was talking about. Jason had let it slip last winter when they returned, that Lisa had a natural all over tan. It was the same s...it optional beach that my mates and I went to when we went to Naples to inspect houses.The folks may be retiring early but were still young at heart and still frisky. I knew Mom and Dad were swinger's years ago but I never thought about Jason and Lisa in that light. I wondered if Jenny knew. It was one bit of information that I was going to keep. Two of the girls dragged themselves upstairs and into the spare bedroom to sleep over. Sharon was still sitting cross legged but had leaned over a little and was sound asleep. After a while Janet asked me if I liked what I was looking at. I didn't realize that Janet was watching me stare. I was embarrassed and mumbled something about not knowing what she meant. Janet looked down at the bulge forming in the front of my pants and gave me a little pat on my hand. She asked me to help get Sharon up. It took awhile but eventually she worked up to another orgasm. We kept fucking off and on for awhile taking different positions and just enjoying the night. When it was way to late to care about how we were going to feel the next day I finally started to feel my own orgasm build. I think she'd been patiently waiting for awhile to see if I'd cum again (and if I didn't masturbate so often I probably would). I told her I was getting close and she asked if she could watch again. To be honest. I slide her panty from her body and removed my remaining cloths while looking at her. She had clean shave pussy, white soft body & perfect piece to fuck. I was thinking what an idiot person who leave this item for somebody else. But I was lucky that somebody else is me to fuck this women. I also got nude lie besides her looked into her eyes & touch her pussy with my finger.As I touch while looking in her eyes she jerked her body and started fingering her with 2 fingers even she also holding me.
