In the dim, flickering light of the metro, a buxom beauty and a rugged stranger find themselves in a secret, throbbing world. Their hands explore, grazing, pinching, teasing. He unzips, revealing his hard, eager cock. She takes him in, her mouth working him as the train speeds through the tunnels. She straddles him, her dress riding up, revealing her slick, ready pussy. With a slow, delicious grind, she takes him in, their bodies slapping together in a symphony of lust, their moans drowned out by the rumble of the train.
