PLEASE HELP ME FIND THIS BOOK:
So I don't know the main characters name but it is a girl and her last name I think is like black. It's a historical romance and the girl was serving like this duchess or lady and throwing a party for her. And then the guy I think was like a lord and Duke or something wanted to buy her off the old lady to be a servant at his place. It's a mature book and I think its long. There is a scene where the main girl is hiding in the closet and the main guys is giving head to this lady and she like thought is was wierd that he wanted her to reciprocate!
Guys please help me find it!!
