we are nudists and have a friend (male) whom we used to spend time with at home in the pool for about 3 years,when in the pool deep end and went to shallow end one of us would pick the wife up and carry her to that end,no problem one sunday he carried her as normal as he put her down she felt he had a hard on and she put her hand on his dick and asked what this after all these years he just shrugged (embarrassed) seen she keep her hand on his dick i went nearer by now i also hard and she also hold my dick i ask her if she want to take it further she say yes if we do so i fucked her on steps when done she pulled our friend nearer and he fucked her by then i was ready for seconds,so there we were friends having a good time that was all, and yes we still visit as always but it has not happened again and we remain good friends has anyone else had something like thing happen.
