He finalizes their slavery, and then both.

Deciding he'd had enough fun with them like this, he took out the Note and wrote, "Shizune and Tsunade Senju are from now on Naruto Uzumaki's sex slaves. They will love to serve and obey him sexually, no matter what he orders or how demeaning they would have otherwise found it, and love calling him Master during sex. This will not affect their relationship outside of sex."

When he finished writing, he watched as their expressions went blank for a moment, before they both grinned at him. "How may we serve you Master?" Tsunade grinned, walking over to him while swaying her body.

Naruto grinned as he sat in her seat. "Well, you can give me another tit fuck while we talk about my apartment building, and Shizune, you massage my shoulders.

"Yes Master!" they both said eagerly, and Tsunade practically pounced on him, wrapping her tits around his manhood while Shizune walked behind him and proceeded to rub his shoulders.

"So, what about your apartment did you want to know Master?" Tsunade asked as she worked her boobs.

"Well, I was kinda thinking about renting some of the other rooms out to help make some more money so I can renovate it, and gave a nice place for my other sex slaves who don't already have a place like a clan compound to live," Naruto replied.

"Oh, I see," Tsunade cooed, before giving his tip a lick. "Well Master, I think you pretty much own the place once you have paid enough out of your missions to buy the building outright, which would be years of high ranked missions generally, then you'd have to pay annual taxes on the property... But I don't think there's anything stopping you from doing that plan even before you own it outright. Short of doing any permanent damage, you're pretty much allowed to do as you like with it, until you have bought it, in which case, you'd be free to demolish it if you wanted. I'll probably have to have you pay a percentage of the rent you collect towards buying it of course."

"Good to know," Naruto moaned as Tsunade engulfed his tip in her mouth.

"I don't suppose you would let me rent a room, my own place takes a good chunk out of my income..." Shizune cooed as she pressed her boobs against the back of his head.

"You implying I don't pay you enough?" Tsunade asked with a bit of irritation at Shizune.

"O-of course not Lady Tsunade!" Shizune yelped a little. "I'd just like to be able to save even more than what I currently am... Plus be close to Master..." she added.

Naruto sighed in pleasure before nodding. "Yeah, I think I can definitely arrange that for you..." With that, he came on Tsunade's face and boobs, before going to get dressed after having Shizune and Tsunade share the cum.

"Come again tomorrow Naruto, we'll need to discuss the decision regarding the mission," Tsunade told him.

He grinned and gave her a thumbs up before leaving the office.
