Switching It Up — Michele Zurlo

As Brea settles into her new life as a D/s switch, treasure hunter, and David's fiancée, her old nemesis Grayson Cuyler resurfaces with a deadly deal. Either David must accept a dangerous, unsanctioned mission or Cuyler will make sure Brea pays for her former life as a thief and con artist. Against Brea's wishes, David and his team take on this impossible task.

Left behind, Brea and her sister/partner-in-crime Jessica hatch a plan that will take them to the Central American country of San Tesoro and put them in the clutches of the man from whom David must steal the prize that will save or doom them all.

Warnings: BDSM, sensory play, anal sex, sex toys, D/s role switching, and chocolate frosting
