In the grimy, echoing tunnels of the metro, a predator stalks his prey. The mark, unaware, is drawn into the dark, forgotten corners of the city's underbelly. The stranger, his eyes gleaming with primal hunger, corners his target, their bodies pressed against the cold, unforgiving wall. With a swift, practiced motion, he lifts the stranger's skirt, revealing a smooth, untouched ass. His cock, hard and eager, pushes against the tight, resisting hole. The stranger squirms, but the hunter is relentless, his thick, throbbing cock claiming its prize, filling the metro with the sounds of raw, aggressive anal penetration.
