Background: I am a practicing nudist and have had numerous erotic encounters over the years. I am 6ft2, of average weight, with a fairly good build and have been told I am above average in the equipment department. All my experiences take place at a nudist beach called Sandy Bay in Cape Town, South Africa.
The Story: It was a quiet weekday at the beach, not many folks around, sun blazing overhead, just the way I liked it. I had settled down next to a rocky outcrop and was completely engrossed in my book. I never noticed the couple approaching until they settled down five meters away from me. Both of them were about 25 years old. They gave me a cursory greeting to which I nodded a reply. They quickly sorted out their paraphernalia, spread their towels and began to disrobe. He was a big guy, easily outweighing me by at least 40 kilos. I kept this in mind while surreptitiously watching them through my dark glasses. As he turned and lay down on his towel (we were facing each other), I had to suppress a snigger, he had the smallest penis I had ever seen. She was stunning. As she hesitantly removed her clothes, casting nervous glances at me all the while, they engaged in light banter. This was obviously the first time she had been to a nude beach. She had long blonde hair and a fantastic tan. Her boobs were large for her slender frame, tipped with beautiful small pink nipples. Her legs were long and shapely and her neatly trimmed bush nestled between her toned thighs. To my disappointment she immediately lay down on her stomach, her legs pressed tightly together. Her ass was well worth looking at though, and I did glance at it without trying to arouse her boyfriend's wrath.
The sun and sea air soon started to take its toll on her libido and she eased towards him for a cuddle. Her soft breasts pressed against his chest while she whispered in his ear. With her moving her legs had parted slightly, offering me brief glimpses of her smooth pussy lips. She shifted even closer to kiss him. Her one leg glided up his, her knee coming to rest just below his limp penis. He broke the kiss and muttered a few words to her. Her pussy was now completely exposed to my view and I had to exert an enormous amount of control not to get an instant erection. Her leg moved higher, rubbing against his flaccid member. With the movement of her leg her smooth pink pussy lips opened and closed ever so slightly. I was starting to get hard. He, to my surprise, showed no reaction to her attentions.
He suddenly jumped up and shouted "hey"! I almost had a heart attack. He had spotted some guy in the bushes behind me jerking off at the sight of his naked girlfriend and was not amused. He stormed back to his towel and muttered to his girlfriend to "cool it, this isn't the time or place". She looked taken aback and quite annoyed. He proceeded to open their beach umbrella and place it on the sand in such a way to obscure them from the prying eyes of anyone leering from the bushes.
