Isolated in his space, he indulges in his private pleasure, his hand working his rigid shaft with increasing fervor. His mind's eye paints vivid images of his deepest desires, driving him closer to the edge. The tension in his body builds, his muscles taut, his heart pounding. With a low groan, he releases, his cock pulsing as it paints his body with his warm, milky cum, a testament to his solitary indulgence.
