Scene Description:

Professor D gives his desperate student Lauren one final shot at redemption, watching her squirm through the exam. The second she finishes, he slashes a massive, mocking F across the page. Lauren's eyes flash with filthy determination—she grabs his pen, transforms the F into a thick, squared A, and purrs for him to upgrade her grade. When he refuses, she bites her lip and scrawls "NAL" after it, offering up her tight little asshole instead. Professor D's cock twitches instantly; he yanks her over the desk, spits on her puckered hole, and rams his thick shaft deep into her ass, pounding his silly slut until she's moaning like the grade-grubbing whore she is.
