Pure Sin (Eden Series, Book 2)

Whips. Blindfolds. Restraints. And a man rumored to be the most skilled Dom in the city... As the BDSM instructor at the hottest fetish club in Los Angeles, Bianca Alexander prides herself on being open, honest, and informative with her clientele when it comes to kink. The fact that she hasn't knelt before a master of her own in four long years doesn't affect her ability to teach, though a part of her longs to be back in her Dom's arms.
But when her boss hires Cade Sinclair--her primary rival from a competing club--to assist teaching her classes, Bianca's comfortable solo act becomes a sinful duet drenched in Pure Sin.
