Ross Shop, a buxom Mexican beauty, entices her chemistry professor, Mr. Blue, with her luscious curves and perfect ass. In exchange for passing grades, she offers him a private lesson in her own unique subject: the art of fucking. Her plump, round ass bounces and jiggles as she rides him, her tight hole greedily swallowing his throbbing cock. The professor's hands grip her generous cheeks, guiding her movements as they fuck hard and raw on the lab table.
