A horny office worker, left alone in the building after hours, can't resist the temptation of his desk drawer. He pulls out a thick, black marker, its cap clicking off with a satisfying sound. His heart races as he unzips his pants, letting his hard cock spring free. He strokes it, his eyes locked on the marker, imagining the naughty things he could do with it. With a wicked grin, he lubes it up and begins to fuck himself with it, his moans echoing through the empty office as he chases his release.
