Big Boy by Skyler Snow

Carter’s having the worst time of his life. He’s lost his job, his mother won’t stop asking him about his love life, and he’s the butt of every overweight joke in the book. Knowing he can’t control everything he decides to change what he can and lose the weight. Maybe then he can find the Daddy he’s always dreamed of.
Samuel loves his job as a personal trainer. Finding ways to help people reach their goals fulfills him. Until he meets Carter. It’s one thing to want to change yourself, but when he sees the man is only doing it to appease everyone around him, Samuel refuses to let that happen. Because Carter is already beautiful exactly the way he is.
A man with image issues. Another who wants to give him the world. Together they’re a Daddy and boy that need each other. But can Carter learn to love himself before he loves Samuel?
