The anonymous allure of the city's subway system sparks a heated encounter between two black coeds. As the train lurches from station to station, they explore each other's bodies with urgent hunger, their kisses deep and desperate. He fingers her, making her clit throb, while she strokes his cock until he's rock hard. In a fleeting moment of privacy, they fuck standing up, her legs wrapped around him, their bodies slapping together as they race towards orgasm, the train's acceleration echoing their own building climax.
