My wife and I are a pretty "normal" couple although we do have somewhat of an adventurous streak when it comes to our sexual lives. For instance we both enjoy forays to nudist venues when we are on vacation. We are also into fantasies and under the right circumstances we have willingly acted out some fantasies. This story is about one of those times.
We had traveled to our favorite city on the west coast and were anxious to hit a couple nude beaches. After arriving, parking and gathering our towels and whatnot we headed to the nudist area of the peninsula. Once into the area we stuffed our clothing into our backpacks and began looking for a place to set up our beach shelter. It was mid morning in the middle of the week so not many others were in the main gathering area although there was one couple a bit younger than us and who were obviously enjoying being nude by performing yoga postures on the sand. We approached the woman, a lively slender creature who was doing cartwheels, headstands and some more difficult yoga poses. We stopped to watch and when my wife applauded her moves she was invited to join in. My wife is petite, slender and Asian-exotic and the two women were a joy to behold. We chatted with them a bit and the ladies helped each other with some "adjustments" for different poses but eventually we told them that we were going to stake out a quiet place near one of the more secluded sections.
Once we had our shelter erected my wife laid out her mat and began doing her postures. I enjoy watching and occasionally join her but some of her postures were quite revealing so I elected to just enjoy the show. Even in the further reaches of the beach there were a few other kindred souls that passed by and several even stopped to take in her moves but there was no gawking or other lewd behavior. I admittedly did make a few suggestions to her about holding some of the poses, such as the down dog, triangle and child pose, longer especially those exposures which provided a good view of her nether regions. She humored me, sometimes. It was fun but eventually we settled into the shelter to watch the river and chat.
When at nude beaches we often share fantasies about what would happen if some nice looking guy approached us and expressed interest in watching my wife closer or even doing more. I have to admit that the thought of watching her putting on a sex show with another guy out in the open has always been an exciting thought and she seems to share my interest in such a prospect. I asked her whether, if there was an opportunity, would she be willing to engage in our fantasy. She responded that if something like that were to become available she would let me make the decisions, her only request being that I tell her what I would let the guy do to her before he did it. She would not say "no" but wanted to know what was coming. That discussion had both of us aroused.
