Two months ago my girlfriend and I went to spend the day in a nudist cove naked as we like. This has been the best experience we have ever had.
In the cove there were few people, three guys camping in front of us on the other side of the cove, separated by the sea and other three people on our side of the cove but where we stood they couldn’t see us.
We had drunk a bottle of wine and she was a bit horny. While we were sunbathing she was grabbing my cock and massaging it until it got big, I responded caressing her pussy and gently masturbating her, she began to sigh with pleasure and without thinking about it she got on top of me and began to fuck me like a little whore until she came three times in a row!! The guys who were camping could see us perfectly, although we don’t know if they caught us.
Then it was my turn, she lay face down, I started to masturbate while groping her big ass, I was about to cum when suddenly I noticed a presence behind me and it was a man leaving the beach. The man caught us and stayed to watch, undressed and stood a few meters from us. I kept touching myself until I came on her ass and left it full covered in cum under the watchful eye of that stranger.
Then she went to bathe in the sea to clean herself, the entrance was narrow and was in the man’s area, so she had to walk in front of him showing him her naked body and her buttocks dripping cum. After a while the man walked around us twice to see if he got a prize, when he saw that we ignored him he left.
