Xisco captures the raw, anonymous encounter of two strangers on a train, seeking solace in the cramped, dimly lit WC. The woman, dressed in a business suit, enters, her eyes meeting the man's gaze. Wordlessly, they lock the door, their bodies pressing together in the confined space. She unzips his pants, revealing his throbbing cock, which she greedily sucks. He lifts her skirt, finding her wet and ready, and thrusts into her, fucking her hard against the cold metal walls as the train clatters on.
