Soothed By Daddy by Kerry Kilpatrick

George Winslow is a little who’s sworn off Daddies and drama after catching his ex cheating. Living alone in his quirky Victorian home has been the perfect fresh start until a spilled glass of precious Lactin Brotherhood milk leaves George completely overwhelmed.
Enter Cyrus Russo, his handy but aloof tenant with his own baggage: he naturally lactates. Moved by George’s distress, Cyrus offers comfort in the most unexpected way—by nursing him.

What begins as a soothing arrangement deepens into something more. George finds comfort in Cyrus’s calming presence, easy smile, and his ability to always fix things, but Cyrus insists he’s not the relationship type.

When a ghost from George’s past returns, Cyrus must decide if he’ll step aside or claim his own happily ever after.
