Turn Your Student into a Cum Addict Slut

You're my teacher. I know you're married, but I also know you want me! After class, I stay behind, pretending I need help, but really, I just want to tease you. You don't touch me but your voice is firm telling me exactly what to do. I take a thick toy and fuck my throat, drooling all over myself while gagging on it. Then you order me to push anal beads deep inside my ass, making me moan as I stretch myself open. Finally, you make me fuck my ass with a vibrator, watching me obey, hearing me beg for more. You don't break the rules, but I know you want to. How long before you finally give in?
