It is that time of year that her father's boss visits for his employee quarterly review. Her father is worried that his pay raise may be in trouble because his wife is ill and he asks his daughter to take over the tea serving ceremony to show respect.
Todd Kressel can't put up with his wife Debbie's constant emasculation and so he leaves. Debbie has grown to hate her husband and so, at least at first, she is relieved. Only once Todd is gone, her 14-year-old son Jarrett makes it clear things are going to change. Unlike his father, Jarrett won't let Debbie walk all over him. He's the man of the house now and, to prove it, Jarrett plans on demonstrating he can make his mom do anything he wants, no matter how horrifying, repulsive or taboo.
A mother and son try to cope as they are experimented upon. This story refers to another author's story as a sort of tip of the hat, but reading that story is not necessary to understand this one.
