In his cramped office, a clerk can't focus on his paperwork. His mind keeps drifting to the throbbing bulge in his pants. He locks the door, unzips, and out pops his huge, fat cock. He spits on his hand, lubes up, and starts jerking off, his other hand playing with his heavy balls. The sound of his hand slapping against his meat fills the room. He closes his eyes, fantasizing, his strokes getting faster, harder. With a final, low grunt, he cums, his load shooting out, splattering onto his desk and office chair, marking his territory in the most primal way.
