In the bustling city, a lone stranger on the metro catches the eye of a curious commuter. As the train rumbles on, their glances intensify, and soon, the stranger invites the commuter to an empty carriage. With a nervous glance at the closed doors, the commuter gives in, kneeling to take the stranger's throbbing cock into their mouth, eager to taste the salty pre-cum. The stranger's moans fill the carriage as the commuter works their magic, feeling the stranger's body tense with anticipation.
