Not Your Shoe Size by Eve Dangerfield

Kate McGrath knows the daddy situation has changed. For one thing her kink’s gone mainstream (what up, internet!) For another, her relationship with Ty, AKA Daddy, has growing pains. After years of protecting herself with faux-girliness, Kate finally feels like a woman. She wants Ty to treat her like a grown up (bedroom excluded, obviously), but emancipation is the first fantasy her daddy doesn’t seem able to fulfil…
Tyler Henderson is happy with things the way they are. And if they have to change, why can’t Kate marry him? That would be nice. And make him look like less of a dirty old man. He’ll fight to keep Middleton where she is, but he isn’t counting on a daddy rival, a man from Kate’s past who would be more than happy to take her off his hands…
Jealousy combines with mistaken identity to throw the status of one of Romancelandia’s top five D/LG couples (at least!) into turmoil. Ty and Kate need to find common ground, but love is a dangerous game, no matter what your age.
