Tall, leggy Lizzy, a curious student, finds herself in her teacher's house, eyeing the massive bulge in his pants. She's always known he had a 'big dick,' but this is her first chance to see it in action. He's stern and commanding, but she's eager to learn, dropping to her knees to take his throbbing cock deep into her throat. He fucks her hard on the desk, her tits bouncing with each thrust, as she earns her A+ in sin.
