Alumna U's anal lesson with her professor is a hard, intense session. She straddles him, her wet pussy sliding along his cock as she grinds, her big ass slapping against his thighs. He grips her hips, controlling her pace, as she moans and squirts. Flipping her over, he fucks her doggy style, her asshole gaping with each deep thrust. The room fills with the sound of their slapping flesh and her wet, slippery pussy. As he nears climax, he pulls out, stroking his cock until he coats her ass with his hot cum.
