Just have her strip and go.

Jett and Esther waited patiently at the motel until a knock came at the door, and Jett went to open it. Sure enough, it was Tomoko and she stepped in. She was evidently off duty, and was just wearing a plain green t shirt and shorts with some regular shoes.

"Um… I think I need you to tell me to do something?" she asked Jett in a questioning tone, not responding as Esther plucked a hair from her.

"…strip naked," he settled on, and she nodded, reaching for the hem of her shirt.

"Not going to have her suck you off, or fuck you?" Esther pouted.

"No," he said simply, uncaring that Tomoko could hear him, as she would forget after leaving anyway. "We'll have her copy to do that with, and I don't want to leave traces of my DNA on a relatively famous hero if she starts questioning what happened to the lost hour or so of her life. Having her strip naked is just to fulfill the requirements of the Sex Note."

Esther shrugged, unable to argue with his logic as Tomoko dropped her shirt and then slid her shorts down, and took her shoes off, before standing and letting him see her body.

"…this good? Can I go now?" she asked, blushing. Jett nodded and she hurriedly got dressed again, and left, her memories of the encounter soon to vanish.

Esther grinned as the hair she took from Tomoko started glowing, and she left it on the floor. "While we're waiting for our new slut to finish growing… what say we have some fun?"
