Under the harsh gym lights, a chiseled, sweaty Adonis finds his own form of post-workout relief. His thick, vein-ridden dick is already at half-mast, wet with sweat and pre-cum. He lubes up, the silicone squelching in his palm, and slips a clear penis pump over his meat. He starts pumping, the water inside the cylinder swirling as his cock grows, the seal tight against his skin. His grunts of pleasure mingle with the clanks of weights, his muscles flexing as he brings himself closer to the edge. The water inside the pump is no longer clear, but filled with his cloudy pre-cum, ready to be unleashed.
