The unmarked door swings open, revealing a scene of carnal abandon. A man, his cock rock hard and pulsating, stands before the line of urinals, his hand working furiously. The sound of his heavy breathing and the wet slapping of flesh on flesh fill the small space. He doesn't notice the figure entering behind him, or the camera capturing his every move. His orgasm builds, his body tensing, and with a final, guttural moan, he comes, his cum shooting out and coating the wall in front of him. The intruder watches, unnoticed, as the man quickly cleans up and leaves, the only evidence of his encounter the streaks of cum glistening in the harsh fluorescent light.
