Cathy and I stand beside the sign that says Nude Beach: No Photography. We strip off our bathing suits and put them in the holdall with our mobile phones and sun lotion. Two naked men approach, one short and dark, the other tall and blond. Both sport large penises.

The blond introduces himself as the beach master with a hint of Scandinavian in his English accent. He says the nude beach is on his private property, at least the access to the beach is his land, so he makes the rules. Unlike most nude beaches, sex is not only permitted but also required, so if we want to sunbathe in the nude, we will have to show how liberal we are by having sex in front of an audience of nudists.

We exchange a surprised look, laugh, flush with embarrassed excitement, and agree to do it. His name is Lars and his friend is Julio. He leads us to the beach and a modified picnic bench facing the ocean. It is low and has attached seat benches on all four sides. He motions us to use it for sex and waves over other naked bathers to come and watch. One young lady is especially cute with a cupid’s bow mouth, long brown hair, generous breasts, and golden brown cunt hair over a delightfully prominent Mount of Venus and pussy slit.

I spread my beach towel on the table and motion Cathy to lie on it on her back. Somewhat reluctantly she spreads her legs wide so the nudists can clearly see her full pussy lips with their trimmed covering of brown hair. The men begin to grow erections at this shameless display. Cathy blushes and closes her eyes. The men’s arousal is obvious as they anticipate watching the fucking about to happen. My penis becomes gloriously stiff too and stands out proudly between my thighs.

I mount the table and mount Cathy. She is already wet. I force the head of my penis directly between her vulva lips and into her vagina. She heaves her pelvis; I thrust myself inside her. We fuck. We heave against each other. My cock feels so good in her cunt. We sweat in the sun. The sand is white. The air is fresh and salty. The beach grass waves green in the breeze. My balls slap against her bum as I thrust inside her pussy.

The crowd of nude bathers has grown larger and gathers close around us. I can see them staring at us, men with aroused penises and women whispering comments about my cock performing between Cathy’s sweet labia. One moves a hand down between her legs to stroke her own cunt. Another moves a hand to her partner’s penis and strokes his erection back and forth.

Having an audience turns me on. I thrust harder and faster. Cathy moans with pleasure and then stiffens in a full body orgasm. A murmur of delighted approval ripples through the crowd. I push Cathy’s ankles up to her ears so my cock fucks deeper into her pussy. The beach master moves behind me for a better view of our genitals in the vigorous act of coitus. Rapid thrusts into Cathy’s cunt and my orgasm hits me. My penis stiffens further and its muscles ripple as my semen roars down my urethra and out my pee hole into her vaginal vault, coating the corrugated walls of her pussy and the perforated bump of her cervix.
