Brother-in-Law by Day, Lover by Night

The King chose my sister to be his Queen. But he chose me to be his obsession. On their wedding night, while she waited in silk and lace, he was in my bed, gripping my hips, burying his face in my neck. Now every night is the same. She thinks he's working late. She doesn't know he's working me. And the worst part? I don't want him to stop.
