The crowded metro car offers no escape as two strangers find themselves locked in a heated gaze. He can't take his eyes off her, and she can't deny the dampness between her thighs. As the train lurches, he presses against her, his erection evident. She gasps, feeling the cold metal of a plug in her ass, her pussy clenching around it. He reaches around, rubbing her clit through her dress as he grinds into her, fucking her hard and fast, the train rocking them towards a shared, secret climax.
