The sway of the train, the crush of bodies, the anonymity of the crowd - the perfect stage for a forbidden dance of touch. The groping begins subtly, a brush here, a squeeze there, under the guise of the train's motion. But as the journey continues, so does the boldness of the hands, tracing the outline of breasts, cupping the bulge in pants, the heat between bodies rising with each stop. The thrill of the unknown, the risk of exposure, the silent, urgent communication of lust in the heart of the city.
