Their Boy by Cara Dee

Left all alone in the world—and in a very big house—after the loss of his parents, Kit Damien has struggled to find his place in society and in the kink community he longs to be a more active part of.
Daddy Doms Colt and Lucas have been a happy, committed couple for eight years. But two Tops need a bottom, and their quest for a Little to make their lives complete has led them to Kit’s empty doorstep.
But just as with his physical wounds, Kit’s emotional scars won’t heal overnight. Colt and Lucas must challenge him at every turn to force him to open up and let them in, to let them use their own individual methods to make him whole again. Together, the three will embark on a journey to learn about true love, growing up, the importance of sprinkles, and the rules of The Game that can make them all winners.
