In the bustling city, a stranger in a suit spots a lone woman on the metro. He approaches her, his eyes fixated on her round, inviting ass. She notices his gaze, a mix of apprehension and excitement in her eyes. He moves closer, his hand grazing her thigh. She parts her legs slightly, inviting him in. His fingers find her wetness, slipping inside her panties. She gasps, looking around to see if anyone's watching. He pushes her against the window, his hard cock pressed against her back. She grinds on him, her breath fogging the glass. The metro stops, and they quickly adjust their clothes, leaving the car as if nothing happened.
