Beneath the city's surface, the metro's rhythm sets the pace for the two women's hearts. As they stand side by side, the car's sway brings them closer, their bodies pressing together. The first woman's hand finds the second's, their fingers entwining. She guides the other's hand to her thigh, letting it linger there, feeling the heat radiating from her core. The second woman's pulse quickens as she feels the other's desire growing, her own body responding in kind. When the train stops, they step out, ready to find a secluded corner to act on their pent-up lust, the city's hum their only soundtrack.
