This is s true story which happened to Claire and i about 4 years ago. We started to take a winter holiday to Fuerteventura every February to cheer us up over the cold winter months. We loved Corraleco especially the grand dunas which is a beautiful beach area with many rock circles for nude bathing. Claire and i hadn't been nude for quite a long time but it's very relaxed out there so we started going out every day to the same spot which was quite secluded. After a few days we started to notice another couple who stopped nearby and we got talking to them. They were a young German couple in their mid 20s. They were a very good looking couple and were very uninhibited. Peter was very good looking and was pretty well hung which was no lost on Claire. Greta was gorgeous with a lovely slim body and great breasts. Both seemed fascinated with Claire's hairy pussy as Greta was shaved. Claire loved being the centre of attention and was getting really very turned on by our two new friends staring at her pussy. This often led to very sexy sessions when we got back to our apartment. Near the end of the holiday after a day spend with Peter and Greta we were left alone in the circle. I couldn't help starting to rub Claire's lovely tits and pussy and we were getting very turned on. In fact so much that we didnt notice Peter and Greta's return. The first we knew of it was when Greta lay down right beside us and Peter started to play with her. Peter's cock was now fully erect and Claire couldn't take her eyes of it. For my art my cock was bursting as i watched Greta being mounted and fucked by Peter. We didn't swap but watched each other fucking and Greta reached across and started stroking Claires body and pussy until we all came. Somewhat embarassebly we all left but often Claire says how much she would have liked to have felt Peter's young cock up her and i can't disagree as long as i could be with Greta
