Tired from a long day at work, the lone man in his office decides to relieve his tension in the most satisfying way he knows how. He locks the door, ensuring his privacy, and begins to slowly unbutton his shirt, revealing his toned chest. His hand wanders down to his pants, feeling the growing bulge. He unzips, letting his hard cock spring free, and starts to stroke it with fervor. The room fills with the sound of his hand moving up and down his length, accompanied by his heavy breathing.
