Yep, he makes clones and fucks them.

Taking his hands from his ears after a moment, Naruto chuckled. "Wow, and I thought I was dumb..."

"Don't push it," Tsunade growled lightly, and Naruto hastily apologized, remembering she only submitted to him on a sexual basis, and would still be quick to clean his clock if he pissed her off otherwise. He then pulled back and stripped himself naked, prompting Tsunade to do the same, getting up and slipping off her already open top, sliding down her skirt, and removing her shoes, then slowly sliding her panties down, slyly smiling at him.

Naruto responded by making four Shadow Clones, and having two each to to Tsunade and Shizune. "You two each get two Shadow Clones to fuck however you please until they pop as rewards for being such good slaves. I'm going to give Sakura here some more personal attention."

Tsunade and Shizune grinned, Shizune taking her clones to a corner in the room, while Tsunade went to lay on the couch.

Sakura smiled and sat in a manner to present her body to its owner, and asked, "How do you want to fuck me Master?"
