In the heart of a bustling city, a man stands alone, hidden from prying eyes behind a shadowy alleyway. His hand reaches into his pants, wrapping around his stiff, eager cock. He pulls it out, letting it hang heavy and throbbing in the cool night air. With a firm grip, he begins to stroke, his movements steady and purposeful. His cock glistens with pre-cum, his balls tighten, and with a final, powerful stroke, he unleashes a torrent of cum. It splashes onto the grimy alley floor, a stark contrast to the city lights that dance around him. He continues to stroke, his cock pulsing with each deposit, until he's empty and spent, his cum dripping from his still-hard cock.
