As the train rumbles on, their inhibitions loosen, and they begin to explore each other's bodies with tentative fingers. Pretty's breath hitches as Cation's hands trace her curves, while Cation gasps when Pretty's touch ignites her core. Their eyes meet, and they decide to give in to their forbidden desires, their bodies pressing together as the train rocks them towards ecstasy.
