Johnny goes into Professor Kendra Lust's classroom to ask her a question related to her course: is the average female attracted to younger men more than older men? Professor Lust tells her student that she's not qualified to answer that question, and frankly, she's a bit embarrassed when her student starts hitting on her. The young stud pushes further and puts his foot on her pussy, pushing her magic button. He does some hands-on field work to find the answer himself, eating her pussy and fucking his teacher until he makes his discovery: yes.
