When Mike has dinner with Bill and his wife Debbie, he is surprised to discover that Debbie is a changed woman - no longer rude and caustic, her attitude and manners have improved drastically, and she is pleasant, polite and charming. He is informed that he himself is indirectly responsible for the transformation, because some time ago he gave Bill two options - either leave Debbie, or give her a good spanking! It is revealed that Bill decided to implement the latter option, and as a result Bill and Debbie's marriage has improved greatly - and so has their sex life. Mike and Debbie give Bill all the details, even showing him their collection of spanking implements, and the false beam in the ceiling, complete with winch, cable and snap hook - all ready for a willing submissive woman and a pair of wrist restraints...

The evening gets even more interesting when Mike informs Bill that they sometimes indulge in their spanking games with Nancy, and goes on to suggest that Bill might like to spank Debbie. Bill is more than happy to do so as Debbie is an attractive woman, and he has long been fascinated by the idea of spanking her. As a respite from the spanking, Debbie is secured to the beam while both men tease her sexually, then later, Debbie rewards Mike with oral sex, and when she has sex with her husband, they invite Mike to watch, and then ask him to spend a whole weekend at their house.
