Homemade video of my lecturer and I in his office: A steamy encounter

The video opens with a close-up shot of a beautiful young woman, who is eagerly stroking her professor's hard cock. The camera zooms out to reveal the professor, who is sitting behind his desk, watching the action with a satisfied smile on his face. The young woman is clearly enjoying herself, moaning and writhing in pleasure as she strokes the professor's cock. Suddenly, the professor reaches down and starts jerking off, his cock throbbing with pleasure. The young girl can't help but smile at the sight of his hard cock, and she continues to stroke him until he cums all over her hand. The professor then stands up and walks towards her, his cocks still visible through his pants. The young lady can't resist him, and she eagerly drops to her knees and starts sucking his cock. She then gets up and turns around, showing off her beautiful, shapely ass. The professor can't take it anymore, and he grabs her and starts fucking her hard from behind.
