On all fours, the man's body glistens with a sheen of sweat, his muscles taut as he drives his hips back and forth, his hand a blur as it works his engorged cock. The room is filled with the primal sounds of his pleasure, the wet slapping of his hand against his flesh, the grunts and groans that escape his lips. His eyes are closed, lost in the fantasy, his body moving with a mind of its own as he brings himself closer and closer to the edge.
