Cora needs to figure out a way to get her study partner interested in math. They’ve got a big test tomorrow. It’s difficult to learn something when you can’t visualize it. Cora thought long and hard how to teach him today’s math lesson. There’s just one way a guy can learn about anything. That’s to somehow make it sexual. She does just that by having two orgasms. They teach him the value of the number two. They also show why he should be studying with her more often. A girl who can get off twice should be a girlfriend. He hasn’t realized that yet. He’s not the sharpest crayon in the box. He’ll get around to understanding that when she highlights the lesson using her body once again.
