The Billionaire's Demon — Eliza Gayle

Just when life didn't look like it could get anymore boring, Melody made a bargain that took her from a plain jane librarian who never got the guy, to a curvy bad girl demon who uses sex as her weapon. Unfortunately for her, there is always a price and she now owes her boss five souls in five days, or else. Time to don the battle gear, Prada and Gucci. Drake is the Master at the Dungeon, the hot new BDSM club in town where anything and everything he wants is his for the taking… including the blonde bombshell who just walked in. Or so he thinks. Melody may look like sin, but a woman on a mission will get what she wants. Him. Torn between duty to his not-so-innocent cause and his need to master the strong willed demon, Drake harbors a secret that threatens their bond, Melody's soul, and even immortality. Whoever said demons are a girl's best friend-lied. Warning: This book includes horny demons with a taste for glass dildos and spanking benches. Need I say more?
