A college student, desperate for extra credit, finds herself in a compromising position with her much older professor. In his office, he locks the door and commands her to strip. She hesitates, but her desire for a good grade outweighs her modesty. She sucks his hard cock, deepthroating him like a good little slut. He pounds her tiny pussy on his desk, making her cry out in pleasure and pain. The old man is insatiable, flipping her around and fucking her from behind, his balls slapping against her clit. He pulls out, his cock glistening with her juices, and she takes every drop of his cum, swallowing it like a good student.
