When her student came over to ask her if she can improve his grade on the test he has taken, she got a great idea. Because she didn’t have sex for quite a while, she decided to make him fuck her, and depending on his performance, she will adjust his grade. As soon as he showed her his big cock, she was already delighted about what is going to happen. So, after giving him a blowjob, it was his turn to show her how skilled her really is. He started pounding her in the cowgirl position, and once her pussy got adjusted to his big dick, he gave her his best in all other positions, getting himself the highest grade.
