Professor Gives JOI to Her Terrible Students

Professor Bea is trying her best this semester, but her students just aren't retaining the course material. Their test results are awful and she's had enough. If they want to be distracted by her hot, curvy body, then they have one more test to pass. She starts instructing the whole lecture hall how to stroke and if they fail, then they failed her course as well. Can you be the student that holds out?
