Baby Doctor - Poppy Field Mpreg Series, #1

Omega Peter Johnson can't accept that he can't have babies. Several doctors have told him he's barren, but he refuses to believe that. After all, there are few things that would be worse news for an omega. He decides to seek the opinion of the premiere fertility specialist in Poppy Field, Dr. Rafe Hexton. Alpha Rafe Hexton isn't known for his charming bedside manner. But he's the best at what he does.
When he delivers devastating news to Peter in an uncaring and blunt manner, Peter sets him straight right before he storms out of his office. When the two men meet at a club one night, Peter ends up in Rafe's bed. While Peter may not necessarily like Rafe, he can't deny how attracted he is to the alpha. Rafe is equally drawn to the younger omega, and finds Peter's infertility a plus in his book. He's not interested in having kids.
But just as the alpha and omega come to a mutually satisfying arrangement, fate steps in and changes the game.
