The stall door swings open, revealing a third twink, his eyes widening at the sight of the two uncut boys mid-piss, their cocks in hand. He steps closer, drawn to the scene like a moth to a flame. The first twink, emboldened by the audience, beckons him in, inviting him to join their lewd game. The new arrival, hesitant at first, soon surrenders to temptation, pulling out his own uncut cock and joining the stream. The restroom fills with the sounds of their united piss, the air thick with the scent of urine and aroused young men, their bodies glistening with sweat and shared fluids as they push each other's limits in this uninhibited, intimate challenge.
