As she steps into the carriage, the door slams shut, and she's face-to-face with a stranger who knows exactly who she is. Their eyes meet, the tension palpable, as the train rumbles through the darkness. The stranger's hand reaches out, tracing her curves, igniting a spark that sets her body ablaze. She's no stranger to sex, but this is different - raw, primal, and dangerous.
