Professional Trainer/Master/Daddy?
Maybe if he found his partner early they could move in together early, he was ready to leave this home and move on to a new part of his life.
He lived with his older brother and his girlfriend, he stayed in his room ninety percent of the time. It's not that they are bad people, it's just that his brother is a Master while his girlfriend is a Slave. They don't abuse each other, they are happy together but they scared him most time, their relationship is way too intense for him so he stays hidden.
His brother loved him, it's firm love with a master, his girlfriend would be all motherly over the boy. But he wasn't that happy, he was missing something, he just didn't know what.
