I am a college professor. Sometimes after a day of teaching, I have a fantasy of having sex with a student after class. Recently, I haven't had any particularly attractive girls in my classes this semester so there's been no one I've enjoyed fantasizing about. But this past summer when I taught, there was a knock-out in my class named Ashley. I see her in the halls occasionally now. Immediately when I see her, I can't help but think -- wouldn't it be great if could go to my office right now and fuck?? I've wondered whether I look at her strangely when I'm thinking this or whether I hide my feelings well.
