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.

Belle resists the notion of a serious relationship with Duncan until Bambi announces that she and former client Byron have become engaged.

The first meeting of Duncan and Ben does not go well, leaving Belle facing a dilemma: which man should she choose to keep in her life?

Belle investigates the other side of the bed by hiring a male escort and experiencing the client point of view, but feels guilty about "cheating" on Duncan - whom she does not realize employed Bambi's services earlier in the evening.
