As this fantasy begins, gorgeous River Lynn (dressed up in a sexy bare-midriff school outfit) is in a classroom and she's seductively asking her professor if there's any way she could possibly get a better grade. The professor knows exactly what she's talking about, and when we next see the blonde beauty she's kneeling on the desk, her upper body bound with rope. She asks her unseen professor how long she'll have to stay tied up to improve her grade. This is obviously the wrong question, and the barefoot babe is promptly ballgagged. She gently struggles and moans in an effort to win the pervy professor's approval and pass his course. But this teacher's pet is going to have to go a little further, and her top is pulled open to free her voluptuous breasts. Then River is frogtied on the desk, reveling in her helpless sexuality. But the moment is broken when they hear a door. The perverted professor immediately makes tracks, and River is dismayed he would leave her there like that. We quickly discover that it's a college official calling for her, and she admonishes Professor Lynn that she can't go on misbehaving with her little roleplaying games while on campus.
