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.
We recently spent a week on vacation on the Central Coast in California, staying in a condo in Avila Beach near San Luis Obispo. We love this area, especially during the Fall when it is still warm, but generally not continually foggy. The area offers places to hike, bike, and kayak, as well as several very nice nearby beaches. Pismo State Beach to the south is wide and a little over 2 miles long, with dunes behind a relatively flat beach. It isn't clothing optional, but its size and the presence of the dunes can offer opportunities for erotic play. Pirate's Cove is probably the best nude beach in the area - maybe the only one. It is not too crowded in the Fall, and tends to be frequented by some of the college crowd from nearby Cal Poly.
While most of the week was engaged in typical outdoor vacation activities, we also tried to fit in some sexy fun.
We arrived in the area on Friday and spent the afternoon at Pirate's Cove. Not much to relate regarding the few hours we spent relaxing in the sun on this narrow nude beach, but a pleasant way to start our vacation.
On Monday we got a chance to spend another afternoon at Pirate's Cove. We arrived at 1:00 and set up our blanket about midway down the beach. We relaxed for a while before my wife decided to get out the Pocket Rocket. For those of you unfamiliar with this little gem, it's a small vibrator about the size of half a cigar. It's a little noisy, but the sound of the ocean makes it easy to use it subtly at the beach.
As my wife sat up facing the ocean, she put up her knees, spread her legs, and openly massaged her pussy with the vibrator. Others on the beach were positioned fairly close by, but they couldn't clearly see what she was doing. The only hints were probably the moans and facial expressions she exhibited as she reached 3 orgasms.
Masturbating in the open on the beach got her so hot that she didn't even stop when several guys walked by along the water. Noone stopped and stared, but a few certainly glanced over and had a clear view as she played with her hot, glistening pussy. She is almost completely shaved, so the view of her wet, swollen lips with her legs spread open is quite erotic. Knowing that passing guys were watching her pleasure herself got her all the more aroused. All this eroticism had the affect of keeping my cock hard most of the time. I would have loved to have pushed her on her back, spread her legs wide, and rammed my throbbing cock into her right there on the beach. I am pretty sure she wouldn't have resisted at all.
She finally put away the vibrator and lay on her stomach. I knew she was very excited and her cunt would be swollen and dripping wet. Laying next to her on my back, I slid my hand under her stomach and started fingering her slippery clit and pussy lips. This is one of our favorite ways to play subtly at the beach, even when other people are fairly close by. As usually happens while doing this, my cock was hard, throbbing, and hovering over my stomach. She moved her hips slightly as I fucked her with my fingers and she quickly reached another orgasm.
