The young coed's eyes widen as she counts the wad of cash, her heart pounding with a mix of fear and excitement. She's never done this before, but the promise of a new phone and rent money is too enticing to resist. Her professor, a burly man with a thick beard and an even thicker cock, leads her to his study. He pushes her down onto his desk, her skirt riding up to reveal her lacy thong. He growls, his hands roaming over her body, pinching her nipples hard through her blouse. She gasps, her pussy dripping with unexpected arousal. He shoves his cock into her mouth, choking her, as he fucks her face, his balls slapping against her chin. She gags, tears streaming down her face, but she takes it, eager for the payoff.
