This is so awkward.My brother's s*xy best friend is now my new boss. Christian used to be a nerd back when we were teenagers. But now, he's a blazingly hot professor. And a single dad. He's hired me as his nanny. The girl who's always lusted after him. It's impossible to keep my distance from him. To ignore the attraction when all I want to do is kiss him. ...and indulge in some really dirty little things. It's true that we should stay...
