Dr. Johnson, a strapping young doctor, finds himself alone in the ER, his massive cock straining against his pants. He locks the door, pulling out his throbbing dick, already leaking pre-cum. He strokes it slowly, his eyes closed, imagining the tight asses and wet pussies of his patients. His hand glides up and down his shaft, his breath coming in ragged gasps. He turns around, placing his hands on the examination table, his ass sticking out as he continues to fuck his own hand, his cock slapping against his stomach.
