The crowded metro car suddenly empties, leaving a woman in a revealing dress and a man in a business suit. He pushes her against the window, hiking up her dress, revealing her ass. She moans as he spanks her, then slides his hand around to find her pussy, soaking wet. He unzips his pants, his hard cock springing out. She turns, taking him into her mouth, sucking him off as he finger-fucks her. The train jolts, throwing them together, his cock slipping into her pussy. They fuck hard, oblivious to the next stop, their moans drowned out by the city's hum.
