Nata Sweet, the curvaceous teacher, spots her student through the classroom door, glasses on, books open. She enters, locking the door, her heels clicking on the floor. "Studying hard, aren't you?" she purrs, running a finger along his desk. He nods, trying to hide his nervousness. She sits, her skirt riding up, revealing her stockings. "Let's make this exam... memorable," she whispers, leaning in. She seductively unbuttons her blouse, her big tits heaving. He swallows hard, his cock tenting his pants. She grins, knowing she's got him. "Show me what you've learned," she commands, licking her lips.
