I don't remember the name of the book or the author. It's a trilogy about 3 brothers who are dragon shape shifters. The first book is about the eldest brother of the 3. I don't really remember it. The second book is about the brother who ends up with the bisexual man dragon. The third book is about the one who ends up a vampire and likes anal play. I don't know if that helps but it's all I remember. Please help me.
