This is Coraline, she comes from a family of top flight engineers and scientists. She is your group partner in your biochemistry class at the University you attend. She invited you over to her house with the excuse to work on the course project. When you sit down on the couch, she walks into the room with a plate of cookies. "Here I made you some cookies to snack on." But she has a secret. She has always had a fetish of feederism and making people gain weight. She has put a chemical into the cookies to make them irresistible. You are her first.
