We have been naturists for many years and have had many holidays in Cap D'Agde. However she is not greatly interested in sex but love showing off her natural and 38ff boobs. In the evenings at the Cap she will dress up in see through clothes. One evening last year we were sitting in the alcove of Johnny Wokkers bar when we got into conversation with a single man in his late fifties or early sixties. During the conversation he told us his wife had died suddenly a few months previously, they had always holidayed at the Cap and he felt he needed to come once more but felt lonely. He went to the bar to buy more drinks while he was gone I jokingly said to Julie fancy a threesome as he was lonely, expecting a curt no, to my surprise she agreed. When John returned we asked him if he would like to come back to our apartment for coffee. He readily agreed. We returned to the apartment and Julie stripped off as she always does I did the same, John asked if we minded if took his clothes, we told him he was welcome, as he lowered his shorts there were signs of a hardening cock. Julie very much out of character started to run her fingers up and down his now hard shaft he started squeezing her nipples making her shudder with pleasure then she took his shaft into her mouth and started to suck, by this time I was just as hard and asked if she would suck both of as the same time, she agreed. After a while she stopped and asked John to lick her cunt, which he did with Julie groaning with pleasure. She then said he could fuck her if he used a condom, by this time my cock was about to burst with cum but I managed to hold back. He rolled a condom over his hard cock and put it in her cunt causing even more pleasurable groans she started yelling fuck me harder I want your cock. They both came at the same time and both lay back, I then inserted my throbbing cock into her wet cunt and gave her my load with john watching still with a hard on. He fucked her once more and after a few minutes catching our breath we had coffee and then he went off into the night. We met him a few nights later and we had a repeat session. The best outcome from this was she was much more interested in sex and we had much fun with a few couples during our fortnight at the Cap. Back home she is always keen to go to swingers club, but that's another story.
