A tall, muscular black man, 'Militar Carioca,' stands naked in his dimly lit room, his huge, dark cock standing at attention. He wraps his large hand around his shaft, starting a slow, steady rhythm. His foreskin moves up and down, revealing the sensitive head of his cock. His other hand cups his heavy balls, feeling their weight, their fullness. He picks up the pace, his breath becoming ragged. His cock swells, and with a deep groan, he comes, his cum shooting out in long, thick ropes, painting his abs and the floor below.
