In the grimy, neon-lit underbelly of the city, Tina Cheri prowls the night, a seasoned flesh peddler with a heart of gold and a cunt as hot as the subway tracks. Her latest mark? A naive, eager boy with a cock as big as the train tunnels he's used to navigating. She lures him into her private car, a den of sin where she teaches him the art of transactional lust. Tina's experienced fingers guide his thick cock, showing him how to make her pussy drip with desire, how to fuck her hard enough to make the train rattle. But will his inexperience be his downfall, or will Tina's tutelage turn him into a true metro man-whore?
