Sadomasochism for Accountants by Rosy Barnes
How can I resist the description?
Paula is still smarting from being called boring by Alan, her longtime boyfriend. Then he leaves her for Belinda, the egotistic would-be partner of accountancy firm Smith, Smith-Brown and Smith. Her mother suggests she spice up her life, so Paula joins the local fetish club.
Luda the transvestite is not fooled when Paula enters Club Liscious. Her off-the-shoulder dress cannot turn her into a thrill-seeking member of the Liscious elite. “She” decides to have nothing to do with the newcomer.
Over the next few weeks, the club-goers’ suspicion turns to friendship, and “boring” Paula recruits Luda, gentle Dominatrix Gretchen, and bossy SlaveBoy to help her win Alan back.
Meanwhile, Alan’s new fiancée Belinda, locked in a bitter battle for a promotion with her paraplegic colleague, starts working on Alan’s own lack of ambition.
Of course, you probably can't expect this in the Sony eBook Store.
