Maybe could be better: Whore-kage or Hore-gake
I also think that will be more interesting start the story showing her already broken and submissive (happily boken and submissive). doing work as a Hokae with work for her husband intermingled.
I think a chapter 1 could start this way:
She is in her office signing missions and deals, while at the same time willingly doing corrupt acts and conceiving whores to make her master/husband happy.
Looking at her ring and remembering her wedding, thinking of herself as a silly, immature girl who didn't yet know how amazing and amazing her husband was just because he wasn't physically very attractive. Remembering their wedding night when he fucked her with that fat, powerful cock of his that made her moan like a whore and showed her pleasures she didn't know.
how he raped her, trained her, punished her, restarted her and taught her how to please her new husband until he turned the current seventh Hokage into his personal cock sleeve. a role that Naruko was currently happy and willing to fulfill.
As that day was their wedding anniversary, she can't help but remember how he had taken the trouble to educate and train her to be a proper and submissive wife. The hot semen he had put in her stomach when she had given him a: "good morning blowjob" still sloshed around inside her and made her anxious about how long it would be before she went home with him.
