Casey's toothless grin widens as she hikes up her skirt, revealing her dripping cunt to the empty train car. She grinds against the hard bench, her juices soaking the fabric as she rides the train's rocking motion. The musty smell of the car only heightens her arousal, her fingers fucking her tight pussy, her other hand squeezing her aching tits. Casey's lust knows no bounds as she races towards her orgasm, the train's speed matching her own.
