A student meets me after class to tell me that he's found my OF account. He knows I make feet content and I am very upset that he discovered my page. 
I ask him what he wants in return for staying quiet, he wants to see my feet. I reluctantly agree if he doesn't tell anyone.
I put my feet on the desk, upset that I have to do this. I show them off a bit and roll my eyes because it all makes sense now, he was always staring at my feet when I wore sandals. 
I can see his cock getting hard through his pants and he demands a foot job or else he will tell everyone. Upset at first, I eventually agree.
