The Master's Plan

They call him The Master because everyone's in awe of his business savvy. I call him my obnoxious new boss, the grumpy b@stard with no people skills and a knack for making women's knickers drop. Sebastian Masterson has everything money can buy, and no one dare refuse him anything… until me. He hates it, I'm fairly sure. I annoy him with both my professionalism and my ability to be a hot mess at any given moment.
Well, the feeling's mutual, buddy.
Things change between us when I'm breaking into his garden (as part of my job, of course) and I accidentally catch him screwing his latest woman. For some unknown reason it puts me on his radar. That's my first mistake.
He says that he wants me. And I tell him he can't have me because HELLO? He's a rich, arrogant billionaire who scowls a lot. Have I mentioned he hates to lose? So, he makes me an offer I can't refuse. His plan is devious and beautiful, allowing me the closure, and okay revenge, I crave. So, I become his fake fiancé. That's my second mistake.
My third? Well, that would be the moment all the fake kisses, thong twanging, and scrumptious @rgasms become too real for me. It's my fatal mistake and there's no way I'm going to survive his new charm offensive. No way in Hell. And then I wonder, do I even want to?
