Alone in his room, a young gay man discovers the pure joy of punheta, the art of masturbation. His smooth, uncut caralho throbs in his hand as he strokes it to full hardness, his breath quickening. He knows he's not supposed to, but the taboo only adds to his excitement. He imagines the touch of another man, the taste of sweat and pre-cum, as he brings himself closer to the edge.
