With the door locked and the world outside forgotten, a man surrenders to the primal urge. His breath ragged, he strokes his length, his grip firm, his rhythm steady. The room fills with the sound of his pleasure, his body tensing as he approaches the precipice. His imagination paints vivid scenes, each one pushing him closer to the edge. With a final, guttural groan, he gives in, his body shuddering as he finds his release, his essence spilling forth in a testament to his solitary pleasure.
