This story is entirely true.
We are a fit couple who enjoy the outdoors, including nude beaches, with sexual play when the opportunity presents itself. She is 45, I am 51. We are professionals living in the Bay Area of Northern California.
One of our favorite beaches is SG - south of Half Moon Bay. This beach is primarily frequented by gay men. A generally pleasant crowd, free of the groups of clothed gawkers that typically hang out at many of the nearby nude beaches. We usually see a few couples, the occasional single female, and a few single straight men. The beach is littered with tons of driftwood that has been used to construct many enclosures (the "condos") suitable for avoiding wind and prying eyes when some privacy is needed.
Many people tend to stay inside their condos, either due to modesty or because they are doing a lot more than catching some rays. Some people like to walk the length of this very long beach - over a mile. We do this, but primarily when the weather permits a totally naked stroll. We especially like the guys who occasionally stroll by with a nice sized cock in a semi or totally hard state. It is pretty common during one of our walks for us to stop and stroke each other into a state of arousal before continuing on our way. Nothing like the free feeling of a throbbing cock, bouncing nearly horizontal, as you enjoy a walk in the sun.
We like to claim a condo (flying a shirt from a stick to stake out our ownership) and park ourselves out front in the open when the weather permits. There are a few condos that we prefer a short distance north of the entrance path down the cliffs. The walls are typically high enough to allow some wild fucking without being seen by the entire beach, but not enough to prevent a close passerby from getting quite an eyeful.
On this Friday in October the forecast was for hot weather, perfect conditions for a trip to SG beach. We love this time of year along the coast. It's often clear and warm enough to stroll naked along the sand. Being a warm weekday, we expected that it would not be too crowded and our time at the beach might get hot in more ways than one.
We arrived at the beach around 11:30. There were less than a dozen cars in the parking lot, so we expected to have our choice of one of our preferred condos. One of our favorite spots was already taken by a single guy, so we decided to claim one a short distance in front, closer to the water.
Over the course of several months we have watched a pair of guys gradually build this condo. The walls are low, varying from 1 to 2 feet in height, providing little protection from the prying eyes of onlookers. The back is open, giving anyone standing up in the condos to the rear an unobstructed view of the interior.
The day was beautiful - little wind and no need to seek protection from the weather. We spread out our blanket in front of the condo, got naked, and proceeded to bask in the warm sun. After a short time, two other couples arrived and set up nearby.
The couple to the south stayed pretty much out of sight in a condo, except when they later took a walk to the north end of the beach. The man appeared to be mid-50's, the woman mid-30's. Both were in good shape and the woman had obviously paid someone for her firm, perky tits.
The couple to the north were both older. They spent a long time setting up a 3-sided wind break with the opening facing away from the water. This obviously was not driven by modesty or concern about the wind, since they both got naked immediately and spent most of their time outside in front of the wind break. In retrospect, it was also odd to face the opening toward the cliffs, since the view of the ocean would be much more pleasant. He spent most of the time sitting in a chair, watching us as I tickled my wife with a feather and stroked her with my fingers.
