Your professor asks you to see her after class and confronts you about not paying attention. She discovers that you've been so distracted in her class because you can't stop fantasizing about her and her body. She tries something a little unorthodox, stripping for you and using her body to tease you, rubbing her asshole and encouraging you to jerk off and cum for her in hopes that you'll be able to start paying attention after getting that out of your system.
