The stepson can't rest in his room and comes to his stepmother to lie with her. She allows, but she didn't expect him to start jerking off. She wants to help him cum so that he doesn't prevent her from reading the book, but when she realizes that he doesn't cum for a long time, she decides that he will help her cum and sits on his big dick.
