The metro's dim light casts shadows on their entwined bodies. His hands roam, cupping her breasts, teasing her nipples through her shirt. She moans softly, biting her lip, eyes closed, grinding onto his thigh. He pulls her hair back, kisses her neck, his breath hot on her ear. 'I want you,' he growls. She turns, kissing him deeply, her hand reaching down to stroke his bulge. The train stops, passengers disembark, but they're oblivious, lost in their lust, ready to explore each other's bodies in the city's dark corners.
