The usually stern professor loosens his tie, his eyes never leaving the young, curvaceous student. She squirms in her seat, feeling his gaze on her like a physical touch. He stands, his chair screeching loudly, and approaches her desk. Leaning in, he whispers, "I've seen the way you look at me, the way you bite your lip when you think I'm not watching." She blushes, but her eyes betray her, filled with a hunger that matches his. He unzips his pants, revealing his rock-hard cock. She tentatively reaches out, her small hand wrapping around it. He guides her, teaching her to pleasure him, his groans of approval spurring her on.
