Sarah's husband Bob has asked his best friend Joe to look after the house while he is away working on the rigs. On the first evening, Joe is astounded to see Sarah and her mate Lisa come down for the evening "dressed to kill." They are popping out to the pub. Strange way to dress for the pub, he thinks, and his suspicions are correct when he sees that she has left her cell phone behind. Checking her calls, he learns that in fact she is meeting another man for a sexual engagement! On her return that evening, Joe presses her on the evidence and gets her to confess. He uses this to his advantage and orders the girls to spank each other on their bare bottoms. When Lisa leaves we learn that Joe is a strict disciplinarian and he begins to use his paddles and canes in an uncompromising manner. This leaves her bottom in tatters. He then decides to call Lisa back and gives her a severe and humiliating treatment, too.
