Bored and horny at work, a tall, dark-skinned man with a huge cock can't resist the urge to masturbate in his office. He pulls out his monster dick, already hard and leaking pre-cum, and begins to stroke it slowly, savoring the sensation. He imagines his coworkers walking in on him, catching him with his hand wrapped around his massive black cock, and the thought sends a jolt of pleasure through him. He picks up the pace, his big balls slapping against his thigh, until he's fucking his fist, his body tensing as he nears orgasm. With a loud groan, he cums, his cock pulsing as it shoots rope after rope of hot, thick cum onto his desk, leaving a sticky mess that he'll have to clean up later.
