There are many many beautiful beaches along highway one in central California. On my days off I used to drive along until I found a good place to park, then would go tan in the open sun. I would strip to my undergear bikini, sometimes rolling the waistband down and making the back nearly a thong. The sun's rays and the wind on my back and the firm sensual sand under my towel would make me horny in no time.
Often the beaches would be deserted or nearly so, with only a couple walking far away down the coastline. At those times I would rise up to my knees, look around at the surrounding cliffs and mountains to see if anyone was around, then would slip out of my bikini underwear and let my erection grow big in the wind and salt spray. I would close my eyes with my face to the sky, smiling, and would gulp in deep breaths of fresh air as I stroked my cock. I would open my eyes and look all around at the beautiful ocean, the sand, the cliffs and caves and fresh rivers running into the sea.
Sometimes I would stand up and sometimes I would curl over into a doggie position. I would cum freely onto the sand, onto my beach towel, into my hand (which then invariably made its way to my lips and mouth). Then I would wipe off the tip of my cock, slip the bikini or shorts back on, and either lay in the sun longer or roll up my towel, walk up to the highway and drive away. One time after squirting a wonderful load into the wind, I looked up into the sun and saw a group of Japanese tourists on the cliffs above me. They were already turning away, but one girl with a camera kept looking back as she walked away.
