The metro's dim light casts long, intimate shadows as a man in a suit and a woman in a trench coat share a secret smile. They disembark, finding a secluded corner. She unbuttons her coat, revealing nothing underneath. His eyes widen, taking in her full breasts, hardened nipples, and shaved pussy. He dives in, feasting on her, her moans echoing in the empty station. She pushes him against the wall, unbuckling his belt, freeing his eager cock. She sucks him, her eyes locked with his, before turning around, offering herself. He grabs her hips, slamming into her, their bodies slapping together in a frenzy. The train rumbles in, its headlights illuminating their entwined bodies, their cries of release lost in the rumbling wheels.
