Indoor hot springs.

Fuu paused, looking at the room that had had some walls knocked down, and some extra support beams put up, though there was a large area without them, and in the middle of the floor, multiple Shadow Clones had dug... "...a hole?" Fuu blinked. She leaned forward over said hole after walking to the edge, which of course made her ass stuck out. Of course, she was doing that on purpose.

"Oh, it's going to be more than a big hole," Naruto grinned, gazing at her ass as he approached. "I'm having an indoor hot springs put in for communal use here."

"Oh. I'm guessing there will be one for men and one for women, and this is just one then?" Fuu asked.

"Nope. Unisex," Naruto corrected.

She turned to him, her eyes sparkling at the idea, and gave him an adorable look, her index finger at her mouth. "Not that I hate the idea, but might that not cause some problems?" she asked.

"Don't worry about it, I have confidence all the tenants will love it," Naruto replied easily, grinning as he knew the only tenants around here would be members of his harem, maybe some friends he could affect a bit with the Note to ensure none of his activities caused problems. He was already looking forward to some communal bathing with his girls.

"As long as you're sure," she grinned and shrugged. "How soon will it be ready?"

"With the amount of hands I got working on it? Two days tops, I got a contractor coming to make sure things aren't going to collapse. I mean, I did use Shadow Clones to study this kind of construction work, but it never hurts to be safe."

"Good thinking," Fuu nodded, impressed. "I think I'll head back to my room now though."
