Surprisingly, Shizune.

"I think I will go with her," Ria grinned, pointing at Shizune.

"Eh? Why?" Naruto asked curiously, as most people would think Tsunade was more attractive, plus he'd made her a cow girl.

"Well, because I already set myself up with a blonde **** girl, and like some variety," Ria replied. "Though a cow girl is appealing, I may be able to get you to make one out of our shared slaves later."

As she went over and started to make out with a surprised, but still happy Shizune, Naruto asked, "What do you mean you already set yourself up with one?"

"Oh, I'm speaking of the jinchuriki, I think that's what your world calls them, in the hospital. I helped her with the Note to get away from the Akatsuki, and just a heads up, she's going to be at your apartment in a very horny state later," Ria smirked as she pulled Shizune's hands to her boobs. Shizune of course wasted no time with feeling up her Mistress for five hours a week.

"Ah," Naruto nodded. "I should get going then, Sakura works fast after all..." With that, he walked out, leaving Ria and Shizune to make out.
