My first serious voyeurism came when I got my driver's license and went to the beach alone. One day I walked a long way along a cliff above the beach, peeking down at sunbathers laying there. When I got to a secluded section, suddenly there was a BBW woman kind of dancing, prancing around giving a show to her boyfriend, and rocking her tits, holding them. She squatted over her bf and he peeled off her bikini bottom, and she rode his dick for the longest time. I was so excited and nervous and stunned I don't even remember if I jacked off while I was watching, but I stayed there all afternoon and jacked off 2-3 times!
Well...I returned--whenever I could! I didn't often find such ripe and sexy scenes, but no matter what I saw, I was very excited just being there and imagining what I might see, and would always cum more than once in the sun and wind and sand. I brought a friend one day, and though we didn't score, we both got naked and masturbated together for the first time. I remember his cum shot all over me!
A few months later I had my own girlfriend, and took her to the beach. We laid there and I coaxed her bikini off of her and masturbated her for a long time, through many orgasms, spread-eagled on the sand. She said it was the hottest sex we'd ever had. We went back there whenever we were really hot. She loved to get fingered, and masturbation there was totally hot for both of us. It was my little secret why that spot on the sand was hotter than any other.
