Her father asks her to take care of her mother and fucks her bareback

Before going on a long work trip this man asks his son to take care of his mother, because he knows he gets very sad when he leaves. The son interprets the situation in a peculiar way and what he does is go to see the mother and tell him that he will take care of everything his father does when he is at home. So he fucks her bareback without finding any resistance from the mother, who loves to have her son fuck her so well and abuse her that way.
