My Secret Fantasies as a Professor

So, I'm 45 and have been happily married to someone who's never been into this kind of thing... but I've always had these fantasies about being tied up in my office by one of my students. Not literally with an actual student though, that would be unethical and illegal, of course. Just as a kink roleplay fantasy scenario between adults. There was this time at the end of last semester when it felt like everyone else knew what I wanted but me... It's funny how we can read so much into nothing sometimes.... Do any other married professors out there keep these kinds of fantasies to themselves? I'd love to hear your thoughts if you have them.....
