Susan Ayn, the bespectacled bookworm, finds herself in a heated debate with her aged professor. As she argues her point, her nympho tendencies get the better of her, and she subtly reveals more skin, teasing the older man. The professor, unable to resist, closes the door and makes his move. He runs his hands over her young body, feeling her firm breasts and tight ass. Susan gasps as he slides a finger into her wet pussy, her resolve crumbling. She finds herself eager to learn his lessons, even if they're far from academic.
