Fantasizing about serving someone I shouldn’t

I’m down bad for someone I should definitely not be crushing on. I’m a college professor, in my mid-30s, and there’s someone in my department working on his Ph.D., in his late 20s, who is super smart, so charismatic, and just an all-around really cool guy. I’m not his advisor, so I’m not in any official role of authority over him, but obviously that power differential is still there, which is why I feel so guilty about it—even though of course it’s not something I would ever act on.

I’m extremely submissive, and with a major fetish for feet, humiliation, domestic service, and more, so I’ve been fantasizing about him finding out, taking over, putting me at his feet, and just taking advantage of how deeply subservient I am. And not even sexually, just turning me into a little simp who waits on him hand and foot. When we’re together, I can’t even bring myself to glance at his shoes because I know I’ll end up staring. I’m just on eggshells making sure I’m on my best behaviour, when all I really want to do is get on the floor and kiss his shoes and worship him and serve him like a king. Like I said, nothing I would act on, but I find myself thinking about it constantly. 🥲
