In the dimly lit, windowless office, a lone man, his face obscured by the shadows, begins to unbutton his shirt. The room is filled with the quiet hum of distant machinery, a stark contrast to the pounding of his heart. He frees his massive, black cock from his pants, the thick vein running along its length throbbing with anticipation. He strokes it slowly, his other hand caressing his heavy balls. His solo dance becomes more urgent, his grip tighter, his breath ragged. The office is no longer quiet; it's filled with the sound of his pleasure, culminating in a hot, sticky cumshot that paints his office desk.
