Not quite enslave her, but...

Naruto opened the Sex Note after a moment of thought, and wrote, "Yugito Nii will not know why, but will feel compelled to obey all of Naruto Uzumaki's commands, especially sexual ones, but despite not knowing why she can't help herself, she will quickly come to enjoy doing as he says, and not worry in the slightest about him being able to control her."

Yugio had just finished fixing her pants which had been inside out from her quick removal of them, before setting them down and picking up her panties. "Drop the panties, and spank yourself," Naruto suddenly told her.

"Huh? What?" she asked, looking a bit annoyed, as she had thought their fun was over at this point, but to her surprise, she found herself releasing the small garment, and letting it fall to the floor, before moving her hand behind her, and spanking her rear end. "Ack! Why… why did I do that?" she asked, looking bewildered, but not at all upset.

"Now…" Naruto grinned as he walked up to her. "Squat down with your hands behind your head."

"What?" she asked, but regardless got herself into the revealing and degrading position. She blushed as she realized it was actually kinda fun to have no control over her actions for some reason, though this didn't seem like her at all. "Um… you gonna just stare, or do you want to tell me to do something else?" she blushed.
