I met Carl and Anna on a nudist beach near Alicante. Carl is 67 and Anna 42.Anna is very very beautiful and as Carl keeps mentioning she loves showing off her nude body.We have become great friends. My name is Bill I am single and 45.One day I was invited to a party at Carl and Anna's. There was about twenty people attending. When I arrived everyone was nude so I joined them.Anna greeted me with a kiss and hugged me with her nude body pressed tightly against me. My cock, not intentionally touched her leg. Anna looked at me smiling and said just as well you didn't have an erection it may have end up here pointing to her shaved cunt.I just laughed. After the guest had left Carl as me to stay on and have a brandy by the pool while Anna cleaned up.Carl then surprised me by asking if I would like to fuck Anna. CARL SHES YOUR WIFE I said. Yes he replied but I am just can keep it up these days. OK if that's what you both want. Carl shout to Anna. Darling I have arranged to have you fucked. Anna walked over to where we sat and said. Carl will want to watch is that OK with you Bill. By now I had a huge hard on. We fucked in front of Carl who was being wanked off by Anna's maid. I was not aware of the maid at first. I have to confess it was totally erotic and we all enjoyed. Anna ordered the maid to run her bath. Anna took me by the hand to the largest bathroom ever. I then sat and watched the young maid bathing Anna. So EXCITING. We fucked again on the bathroom floor as the maid looked on.
