The metro's hum echoes as the woman's dress falls to the ground, exposing her glistening, shaved pussy, barely concealed by a thong. She grinds against the stranger, her wetness seeping through the flimsy material, driving him wild with desire. He reaches out, tentatively touching her throbbing clit, feeling her body tremble in response. As the train approaches, they rush to a nearby alcove, the woman pulling him down to taste her eager, dripping cunt, the metro's rhythm accompanied by her moans of pleasure.
