Of course they show up

"Belay that order!" Hinata froze, then turned around and lightly bowed her head towards the brown haired young man who superseded the authority of the lewd lesbo. He was nude from the waist down as was typical among the men here, wearing just a white buttoned shirt. A white-collared girl was using her mouth to get him hard. She had long brown hair arranged into bangs on the side and a ponytail. She was on a leash being held by him. They looked like siblings, and this was proven shortly after in conversation.

"Keigo. Your sister Mizuho keeping you satisfied there? Must be nice making that bitch serve you now. You want to give me another turn with her?"

"Oh Chizuru. I overheard. I'm going to enjoying breaking you into a true bi. Sure, I've enjoyed your service plenty and you've really learned how to pleasure cocks, but turning someone is one of man's greatest fantasies, and the last one I haven't experienced yet."

Chizuru looked worried and Hinata just watched this unfold. She was still absorbing the idea of legalized ****. She knew her clan flirted with the idea at one point, but they never crossed that line. She remembered Hanabi telling her she used her Byakugan to compare dick sizes of her dad and Neji, then dismissing it as a joke. She briefly fantasized about her sister getting double penetrated by them before banishing the thought and focusing on the present.

"Wouldn't you rather find Hime and Rangiku and have a foursome with them and your bitch sister?"

"Done that. Amazing. Now I order you as a man to ride my cock, unless you want a collar of your own."

She surrenders and uses a basic transformation jutsu to expand her tit size to Rangiku level, as he had ordered some time ago she do whenever he uses her.

"Yes Keigo-sama, I would be glad to service you. As a bimbo, I love serving cocks. Teehee." She said, like she was reading from a script.

Mizuho gets out of his way and taking her leash, hitches it to a post seemingly there for this purpose.

"Your cock is fuck-ready Onii-sama. I look forward to my next order." She said demurely, remaining on her knees.

Soon enough, Chizuru squatted down on top of his crotch and lowered herself onto his cock before riding it with abandon. Hinata took the opportunity to try and walk away before Keigo noticed and verbally stopped her.

"Where are you going big-tits pink collar? Looking to service an unoccupied cock? I have a friend around the corner who prefers older women but wouldn't mind a girl of your figure either. He has a mature kunoichi bitch on a leash; probably riding her either literally or figuratively. Service him."

"Oh, okay then. I'll go then. Break her good then."

Over the course of this, Chizuru had already cum three times and was nearing a fourth.

"Damn, cock feels so good. You have to make every woman addicted to this?"

"That's the founding principle of this village, to make every female, young and mature, peasant and princess, civilian and kage, a cock hungry sex **** to all men. Our will of libido."

"Cool doesn't suit you, you know."

"I won't have to put up with that attitude for long after I melt your mind with pleasure."

"I would love for you to do that."

Later, after using the last of her free will to procrastinate the meeting, Hinata's collar finally turns red and she quickly finds the other young man.
