The chubby professor's thick cock tents his pants as he watches his young student bend over her desk, her tight ass cheeks inviting him closer. He can't resist, moving behind her, his hands gripping her hips. She looks back, her eyes wide with anticipation and fear, but she doesn't pull away. He unzips, his massive cock springing free, slapping against her ass. He rubs the head against her slit, feeling her wetness. She whimpers, her body tensing as he pushes inside, her tight pussy struggling to take his girth. He slides in slowly, filling her completely, her virgin walls clenching around him. He starts to move, fucking her slowly, deeply, teaching her the true meaning of education.
