Under the stern gaze of their professor's portrait, a dominant student teaches her submissive partner a lesson in femdom fucking. She commands him to kneel, his face level with her crotch, as she slowly peels off her panties, revealing her smooth, wet pussy. He leans in, eager to please, but she smacks his cheek, "Not yet. You'll earn that." She sits on the edge of the desk, spreading her legs, and orders him to pleasure her with his tongue. He obeys, tentatively at first, then with growing enthusiasm, lapping at her clit and sliding his tongue inside her. When she's ready, she commands him to stand, unzips his pants, and strokes his cock until he's rock hard. Then, she turns around, bends over, and orders him to fuck her hard, just like a good student should.
