Starts by having Akemi strip her.

"Hey Akemi, come in here," Naruto called, and Akemi walked in to see the sleepwalking Tenten.

"What did you need?" Akemi asked Naruto.

"Help Tenten here out of her clothes," Naruto told her.

"Oh, sure!" she said, walking over. She was starting to mildly enjoy being told what to do, so there were the barest traces of enthusiasm in her actions.

She got behind Tenten, and undid her night robe from behind, pulling it off her shoulders and down her arms. 'This is actually getting a little fun,' she thought as Tenten's chest was exposed to Naruto. She let the robe fall to expose her black lace panties as well. 'Earlier I was just fine with doing what he wanted, but it's actually almost enjoyable now..."

She then grabbed the waistband of Tenten's panties, and pulled them down as well, leaving her naked except for her shoes and her robe pooled around her ankles with her panties atop them, but that was fixed by Naruto having Tenten step out of them, before he had her bow and start kissing his feet.

"Now Akemi... Sit in that chair over there and watch. Masturbate while you are at it, but don't cum until I let you."

"Alright," she nodded, walking to the chair and sitting, before spreading her legs and putting her fingers to work on her snatch.
