A precocious Russian student, her huge natural tits straining against her blouse, finds herself in her professor's office, eager to improve her grade. She's got a naughty idea of how to do it, and starts by teasingly unbuttoning her shirt, revealing her plump, ripe cleavage. The professor, a beefy man with a big cock, watches in approval as she drops to her knees and takes his throbbing member into her mouth, working it expertly with her tongue. He returns the favor, fingering her wet pussy and even pushing a finger into her tight asshole, making her gasp. Then, he bends her over his desk, slapping her ass before plowing into her from behind in a rough doggystyle fuck, making her huge tits bounce with each thrust. She moans loudly, her orgasm building, as he pounds her hard, making sure she learns her lesson.
