Professor's Pet gets caught plagiarizing, but Mr. Stern has a special kind of detention in mind. When the ebony freshman drops to his knees for some after-hours tutoring, he learns exactly what it takes to pass the class. Watch as chalk dust flies and these two make the teacher's desk rock with private lessons that go way beyond the syllabus. The young stud discovers that his oral skills are perfect for earning extra credit, and the professor's thick chalk isn't the only thing leaving marks before class is dismissed.
