The metro's dim lighting casts eerie shadows on the anonymous faces pressed together in the confined space. A woman, her heart pounding, feels a hand on her thigh, moving upwards. She's wearing a short skirt, no panties. The stranger's fingers find her bare, wet pussy, stroking her folds, rubbing her clit. She's sandwiched between bodies, unable to move, only feel. The train lurches, his fingers slide inside her, and she bites back a cry. The doors open, and they're separated, but the heat remains, a tangible force between them, a silent promise of a fuck to come.
