King Daddy by Charity Parkerson

He’s the most hated and dangerous man in town. The only good thing he’s ever done for this world is his sons. That probably won’t change.
Beau is the biggest weapons dealer on the west coast. He built an empire from the ground up. Having the world at his fingertips, and giving the world to his family, cost him everything. He went from having a beautiful life to having a drug-addicted wife and son. Then he lost it all, except the money that brings no warmth. He’s bitter and done. That’s not a good combination for someone as deadly as him. There’s only one person who doesn’t fear him or look at him with disgust. Kylo has no idea how much danger he’s in.
Kylo lives in his head. Always has. For the most part, that’s fine. He doesn’t have any responsibilities, so he’s free to be his Little self. The only area he’s lacking is his love life. There aren’t many men out there searching for someone strange like him. It’s one thing to be a Little, but to also be odd is too much for most people. Beau looks at him in a way no one else ever has. It’s too bad the guy could get him killed. He’s not the first.
