I posted a sarcastic answer then deleted it. Then I realized this could be the further story: The artist who'd been chronicling the two couple's evening now turns in his work, and they're not satisfied. Between the quality of the drawing and his initial sarcastic comment, the two couples decide he needs to be punished. Sallie is released, and the artist is locked into the bedboard in her place. The girls spank him. Then the guys spank him as well. The artist is mortified but also fantastically turned on. I'll let readers imagine the rest...
