The dimly lit train car is filled with the hum of bodies pressed together, the air thick with anticipation. The groper's eyes scan the crowd, settling on a pair of shapely thighs clad in a short skirt. He moves closer, his heart pounding in his chest. As the train jerks to a start, he makes his move, his fingers tracing a line up her inner thigh, feeling the heat radiating from her core. She gasps, her body tensing, but she doesn't pull away. Encouraged, he continues his exploration, his touch growing bolder, more confident, as the train races through the night.
