The metro's dim lights cast an erotic glow on the two women, their bodies swaying to the rhythm of the train. They stand close, their legs touching, as the train speeds through the tunnel. The taller woman leans in, her breath hot on her companion's ear, whispering filthy promises. The other shivers, her heart pounding in her chest. The taller woman's hand slides under her skirt, finding her wet and ready. She fingers her slowly, expertly, as the train pulls into the next station, the doors opening to reveal a crowd of commuters, completely unaware of the heated encounter unfolding before them.
