In the dimly lit metro car, two anonymous figures stand close, their reflections in the dark window revealing their secret. They don't speak, but their hands tell the tale. Zippers descend, and they each reveal their hard, throbbing cocks, stroking them slowly, eyes locked on the other's reflection. The train's movement lulls them into a rhythm, their cocks brushing, a spark igniting. They can't resist any longer, turning to face each other, cocks touching. The train screeches to a halt, forcing them apart, but the encounter has only just begun.
