The voyeuristic thrill intensifies as they notice each other's reflections in the mirror, their hands slowly moving to their crotches. Brown, blond, and black hair sway as they stroke, their dicks growing harder. The first stream of piss hits the floor, the sound echoing, and they're off, their self-pleasure becoming a dance, a challenge. The room is a symphony of wet sounds and heavy breathing, their gazes locked in the mirror, their bodies tense with anticipation.
