The metro car fills with the scent of sex as the stranger's cock throbs in the woman's mouth. He grabs her hair, fucking her face roughly, while his other hand works her pussy, making her squirm. She grinds on his fingers, her clit throbbing against his palm. The train slows, and she pulls away, panting. "We can't," she whispers. "Not here." But he drags her into the next car, slamming her against the window, her bare ass pressing against the cold glass. He enters her from behind, fucking her hard, his balls slapping against her. The train rattles, their bodies slapping together, their moans lost in the din.
