ooooo, you are such a bad teacher! I can see you staring at My feet all during class, tripping up your lecture because you can't get your mind off the idea of sliding your cock against My soles. Don't think I don't know your dirty secret, and don't think I won't use this as leverage! I guess you'll just have to do what I say, get Me what I want, and make sure I get an A+ in your course. We wouldn't want anyone finding out about your naughty fetish, would we?
