Slave to Your Professor

Slave to Your Professor by texturedshroom

OK, slave... now stroke it as hard as you can while you look at my ass. But do not cum. In fact, from now on, you will not cum without my permission! If you do, you will not get to pass my class. And trust me, I'll know if you do. You are going to come and see me every day, outside my office hours. If I detect your balls aren't swollen when they should be, then that's it! You go back to normal and you fail my class. Unless you want to lose your job and be a 5th-year senior... you better listen to me!

I can be your best friend or your worst enemy... so which is it going to be, slave?
