My wife and I were at a clothing-optional resort, and after spending the afternoon naked around the pool we went indoors to check out the gift shop. Still nude, she picked out a dress and took it to the counter and asked the (also nude) saleslady where she could find the dressing room to try it on.

Now, consider the situation: the only clothes anywhere in the shop are on the racks and hangers, and everyone there is nude.

Saleslady replies: "Dressing room? You're not wearing any clothes to take off! Look around, everyone in here, including you, is already naked." Gotcha!

Having been caught out in this joke that my wife had unknowingly set on herself, she figured she owed everyone there something. So after slipping on the dress (a short sheer shift with small lace patterns) she made a few twirls and pirouettes, then turned away, spread her feet and bent over like she was adjusting her sandals and treated all to a full view of her asshole and the underside of her pussy. A rare (but coveted) sight even at a nudist resort! (She told me later that really she was mooning them for laughing at her.)
