A stern professor, fed up with a teen's disobedience, decides to teach her a lesson in manners the hard way. He orders her to stand, her short skirt riding up to reveal her bare, untouched pussy. He commands her to her knees, unzips, and presents his hard cock to her innocent face. She tentatively licks, then eagerly sucks, her inexperience clear. He disciplines her further, pushing his cock deep into her throat, making her gag. He then fucks her mouth relentlessly, his thick cock sliding in and out of her lips. She struggles to keep up, her face a mess of saliva and pre-cum. Finally, he pulls out, his hot cum splattering across her face, dripping down her chin. She tentatively licks her lips, tasting her newfound debauchery, her innocence forever lost.
