I am sex. I have built my image, client by client. I call myself successful because they call me mistress. It doesn’t matter who I am involved with. My arrangements always start with a contract. No exceptions. Until them. The sweet couple who walked into my class and shake everything up. Luke wants to be dominated. His wife, Camila wants to dominate. Who am I to say no to a couple who is eager to learn. Except contracts aren’t made to protect feelings, especially the ones I never saw coming. They have what I want—what I’ve been missing. But I’m what they want. Can I let them in? Or will I always be on the outside looking in? **This is a FFM romance. Please check your trigger warnings**
