One of her students 18+ makes up an exam

Prof. West is making some hot tea in some really inclement weather. She hears a knock at her door and its Dane Cross, one of her students that was supposed to come over to make up an exam. But the weather was so bad, she didn't think anyone would come, but there he was bedraggled and soaked to the bone. She ushers him in, gets him a towel, and makes him some hot tea. She is so shocked at his dedication to her class, that it actually turns her on. They are alone in the house, and she has no problem convincing him that his cock is exactly what she wants right now.
