Punishes her son forcing her to eat her pussy and fuck her for getting bad grades

In some wealthy families getting bad grades and losing money to your parents who pay for the private academy and private lessons is punished for everything. This mother is up to the noses of the fool of her son's ass and punishes him forcing him to eat her pussy, something that surely being so geek has never done in life. But it does not seem enough, so he tells him that he is going to turn him into his little bitch and that he is going to squeeze that shitty cock that he has to give himself pleasure when he feels like it. He sucks it to make it hard and fucks him like the most fucking mother.
