Teaching Them A Lesson

Professor John Buchanan is used to students begging for better grades. In his History 100 classes, where the students never pay attention if they even bother showing up, he gets it more often than not. He's gotten pretty good at turning them down and wishing them luck on retaking the course. But when two of his students give him a good look under their skirts, he finds it harder to turn them down. When they offer a threesome for better grades, he finds he can no longer say no.
