In the Season 3 premiere, Belle's book is a success but she worries about having enough material for a follow-up tome. Belle's sister Jackie shows up on her doorstep needing a place to stay after leaving her unfaithful husband.

Belle tries to broaden Jackie's sexual horizons by taking her to a fetish club, with surprising results. Blocked in trying to write another book, Belle seeks support from her editor, Duncan.

The sexual attraction between Belle and Duncan heats up over a late-night chat session, while Jackie wants her sister to accept that she and Ben are now a couple, and Bambi ignores Belle's warnings and falls for a handsome client.

Belle provides sage counsel to Ben regarding his failing relationship with Jackie, and to Bambi over her romance with her client, Byron - but she promptly ignores her own rules with Duncan.
