His at Night(His #1) by bourbonvanilla
Summery:
When her boyfriend cheats on her, Rory Warren moves to a new flat. She get a flatmate who becomes a very good friend of her. But that flatmate has a very sexy, very charming and very wealthy brother who turns Rory's world upside down.
Rory is a weak woman. Braden Campbell makes her even weaker. He's a controlling businessman and a perfect definition of a womanizer. He doesn't do relationships.
His past has taught to be tough, unforgiving and cold. He doesn't have a word 'commitment' in his dictionary. He works hard. He fucks even harder.
Rory and Braden make a pact, an arrangement. They want to stick to it, follow their rules. But one can only bear so much before bursting.
It's a game of two and the rule is simple: if one of them falls in love, it's game over.
