The sun beats down on the deserted beach as a lone surfer, wearing nothing but a barely-there bikini bottom, indulges in a private, taboo pleasure. He lubes up a 500ml bottle, his heart pounding with anticipation. Kneeling on the sand, he spreads his cheeks, revealing his tight, pink hole. With a deep breath, he guides the bottle in, gasping as it stretches him wide. The bottle glints in the sunlight as he fucks himself, his body tensing and relaxing with each thrust, his cock aching for release.
