He makes her beg first.

"So Anko, do you want me to fuck you?" Naruto asked.

"Oh, yes Master, please, I want you to use me, and enjoy me," Anko cooed, straightening up.

"Slither over her, and beg me for it," he ordered her.

Blushing, she did so, and lowered herself down to waist level. "Please Master, please fuck me... Use my body..."

"I dunno, you're not sounding quite sincere," he teased her, knowing that she was enjoying even this, and wanted to see just how far she would go.

"Master, I am your slut, your ****, your fuck toy," Anko moaned, bowing before him. Her pride was completely gone, now she only knew joy from submitting to him and demeaning herself for him. Of course, she knew full well he saw her as more than those things, else he would have her as his **** full time and not let her maintain her personality otherwise, this was just for fun during her sexual servitude. She had figured out he had done something to her by this point, and it had something to do with the Notebook he kept writing in, but she didn't care anymore, she just wanted to serve him right now, then maybe go for some Dango once he was done with her.

"Master, please use your sex doll, she is here to serve and obey you..." she cooed, shaking her tail a little.

"Well, if you mean it, kiss and lick my feet," he ordered.

"Yes, thank you Master," she said, sincere in her gratitude for the command. She actually liked the degrading nature of it, as it let her show just how much she would do for him now, and she started to kiss the top of his feet, before letting her tongue out to clean the sweat from between his toes.

Naruto grinned down at her, he didn't even particularly like foot stuff, but her submissiveness was very hot. She was completely helpless before his will now, and she loved it. He thanked whatever divine intervention that had given the Note to him.

...

"You're welcome!" Ria had the strange urge to say in some random location as she was familiarizing herself with the Universe. It was close to time she would have to pay the lucky soul that had found her gift a visit.

...

Naruto then told Anko to stop, which she was actually slightly **** about, before looking up at him.
