The Subject Was Rose (The Sunset Palomino Ranch #2)
Karen Mercury

Drake has led a shallow, jet-setting lifestyle for decades. Just as he decides to open up and allow a deeper relationship with Rose to form, he's confused by his heteroflexible passion for Jesse Factor, too. Drake initiates the couple into the intricacies of his sexual power structure, and they all want much more than a trivial hookup.
But Drake is haunted by a corrupt deal his father made fifteen years ago. Now greasy fed Burt Macklin is back demanding a multi-million-dollar payoff for a large chunk of his ranch, and his violent threats could spoil the perfect ménage.
