A teacher licked a student's pussy and made her an excellent student after sex

The girl can't seem to get any knowledge, because she thinks about something else entirely when she comes to class. Her crush on her teacher makes the bitch look for casual encounters and she goes to her office to meet the man there alone. The no-nonsense dude understands what the cutie wants and puts a toy in her mouth to show her what she can do. Then the man swaps the rubber cock for his real one and the hottie sucks him so good that she gets a cunnilingus in gratitude and then fucks him.
