Anal sex was really difficult for her, she couldn’t help but cry every time, and often passed out while her ass was being pounded by the men who fucked her. However, her physics professor promised to help her practice every day until she was the perfect anal whore. She was so thankful, after all, most of the men who fucked her wanted her ass almost exclusively, so she needed to be able to take an ass fucking. She made sure to thank him with a blowjob after every session.
