A sexy single billionaire businessman. A YouTube star. And the hottest night of their lives.When I first saw him, I thought he was too hot for his own good and too cocky to resist. The perfect rebound from my break-up from hell. So I threw my usual rules out the door and challenged him to an anonymous hook-up. No names, no strings attached. It left me aching in more ways than one.So imagine my surprise when I show up for the first day of my new job...
