Christian was still getting used to being a boy. He thought he'd be living his dream life with a daddy who would take care of him and provide for him, allowing him to do anything he wanted. He quickly learned that wasn't the case, strict rules imposed on his life in his new relationship.
Boys don't deserve to sleep on sheets. All Christian was allowed was a mattress pad on his bed, the sheet soaking up his sweat and cum directly for him to sleep on. He wasn't permitted to have body hair, forced to shave himself smooth so nothing came between his skin and the filth, his body on full display for the men he was whored out for. It was mandatory to sleep facing down, allowing immediate use of his hole at any time.
The rules were repeatedly engrained into him until they came naturally, his spirit broken and shaped the way his daddy liked. Soon he couldn't imagine living any other way, the need to please his sir rooted to his core, wanting to do anything to make his sir happy. He wanted nothing else in life than to be daddy's boy.
