My best CFNM experience was one Saturday my wife had gone shopping with friends and I decided to do some nude sunbathing in our secluded back garden which no one overlooks. I was lying naked on the lounger, half asleep, when sudden I heard a female voice "Excuse me, we're doing a survey, have you time to answer some questions." I looked up and standing looking down at me were two very attractive young women. Before I could say anything, they apologised for the intrusion but said our neighbours had said someone was in and that were were probably in the back garden, they should just go round. They were smiling and didn't seem to be put of by my nudity and I could see each glance at my exposed manhood. I agreed to answer their boring questions. They both sat down on the empty lounger right beside me and ticked boxes and wrote notes. I had the CFNM pleasure of 15min with two stunning twenty somethings. Then they thanked me, said I could get back to my sunbathing and left.
