Blonde coed, eager to boost her grades, drops to her knees in front of her stern professor, offering her luscious lips and skilled tongue in exchange for extra credit. She expertly takes his substantial length deep into her throat, gagging slightly but enthusiastically, as she works her way up and down his shaft. The professor's groans of pleasure fill the room as he grips her hair, guiding her pace. She cups his heavy balls, gently massaging them as she increases the intensity, her spit glistening on his cock. As he nears climax, she looks up at him, her blue eyes watering, and he explodes into her waiting mouth. She swallows every drop, licking her lips clean.
