In the grimy, unisex public toilet, a lone man stands at the urinal, eyes darting nervously as he unzips. His massive cock pulses in his hand, veins throbbing as he strokes vigorously. The sound of his wet flesh slapping echoes in the empty restroom. He's close, his breathing ragged, when suddenly, a woman enters. Frozen, he can't stop, and she watches, captivated, as he groans loudly, his balls tightening. With a final, powerful stroke, he unleashes a torrent of hot cum onto the filthy floor, his body shuddering with relief.
