7.0Black Scorpion Entertainment presents Man Island, a hypnotic-erotic shipwreck fantasy that creates a sexual dynamism unlike anything seen in recent gay porn history. Black Scorpion went all out and rented a secluded island in the Mexican Gulf. By doing so, the cast and crew was able to take advantage of the island's multiple stunning settings, day and night. Each scene was an experiment in high-caliber filmmaking, as director Rafael Alencar and videographer mr. Pam teamed up to create a gay porn fantasy that's sexy, sultry, and completely distinctive. Lost at sea, D.O. swims ashore to what he thinks a desert island, but he soon finds hottie Mario Perez. They proceed to make out, with one of the hottest ass-eating scenes ever filmed. For "better access" they climb a tree, and then fuck in the tree - the chemistry is perfect. Once out of the tree D.O. has Mario up on a tree stump and finishes him off.
