The metro's rumble echoes her heart's pounding. Her breath hitches as he nears, his body heat radiating. He's a stranger, yet his confident, predatory stance ignites her. His hand joins hers, guiding her movements, his thumb rubbing her clit in expert circles. She gasps, her pussy clenching. He's hard, his cock pressing against her thigh. The train stops, passengers disembark, but they remain, lost in their intense, silent tryst, teetering on the edge of release.
