Cindy has a crush on popular Billy so she buys him in the high school "slave auction." She then asks Stephanie to trade slaves with her so that Stephanie can ask Billy questions and report back to her. Stan enlists Lena to help him find the mystery woman he drunkenly got together with at a party -- the one who occupied a leopard skin bra that was left on his bed. While finishing up a project late at his place, Janice and Carl decide to mix work and sex.

Stephanie asks Billy questions and they wind up kissing, while Cindy uses whipped cream and Oliver to make Billy jealous. Stan confesses to Lena that he couldn't make a move on Renata after she fit the "glass slipper" bra. Carl gets suspicious when Jacob calls and says he loves Janice's ideas, which were actually Carl's.

Stephanie and Cindy switch slaves so Cindy can be with Billy, but Billy and Stephanie wind up together. Stan enlists Lena to find the right girl to fit the bra, but Lena tells him she's been the right girl all along. Jacob and Janice return from dinner, and Jacob reveals that he and Janice also had an affair.
