As the rain pours down, two anonymous gents seek refuge in a grimy, abandoned tube station. Their eyes meet, sparking a silent understanding. Unzip, and the first warm stream hits the concrete, the sound echoing in the empty space. The second man watches, entranced, before joining in, his own piss joining the puddle. The air is thick with the scent of urine and testosterone, their cocks hardening as they finish. They exchange a nod, moving closer for more.
