Create a portrait of a slender, youthful twink, featuring a sharp, defined chin and high cheekbones, plump lips, long dark eyelashes, and captivating, glowing green-yellow eyes. He has curly dark brown hair on top of his head, shaved short and faded on the sides. Chiseled, defined, toned body with a swimmer's build, little to no body hair, short with an average-sized cock that sticks up and throbs when erect. He is at a private pool with a slim Speedo-like bathing suit on, barely covering his bulge and his butt cheeks. The background is of a beautiful sunny day with palm trees.
