"Well, I want to see what it would be like to put a thin layer of my skin over your body. Maybe I would be able to control the way you move..."
Jon was amazed at the possibility and agreed readily.
"Okay," Zoe exclaimed, happy that Jon was so open with her. "This may feel a little weird."
She took off her arm at her shoulder and set it on Jon's stomach. With a frown of concentration, she made her arm melt and spread out into a puddle that defied gravity. Then, with even more effort, Zoe willed that puddle to spread out over Jon's body.
To Jon it felt like someone was spreading butter over his body, and he could feel what was once Zoe's arm reaching down to his fingers, enveloping his penis, ass, and legs. Finally, everything from Jon's neck down to his toes was covered with Zoe.
Zoe was sweating a little from the effort, but smiled at Jon when she saw that he was almost completely covered with a very thin layer of her body.
"Okay," she said quietly. "Now the hard part. I'm only used to moving that arm in a way that an arm can move, so now I have to concentrate on moving parts of your body using just bits of skin or muscle that may have never had any involvement in moving my arm originally. Jon, I need you to stay completely relaxed. Please don't resist me.
Jon complied, and laid back, keeping his muscles completely relaxed.
Zoe focused on Jon's hand and imagined his little finger moving up and down. To her surprise (and Jon's), it worked! She moved up to the whole hand, finding she could move each finger almost intuitively. Then the arm, and then she made Jon sit up, move his legs off the bed, and make him walk around.
"Oh my god, Jon! This is so much easier than I thought it would be. I can control everything you do!"
"This is so weird, Zoe." Jon said from across the room. He was doing the Thriller dance without willing his body to do so.
"I know!" Zoe was thoroughly enjoying herself. "Jon, could you try resisting my movements?"
Jon contracted all his muscles at once, and attempted to simply stand there and not move. But all it did was make his muscles cramp up. And he found himself still doing the Little Tea Pot dance.
"I can't stop it!" Jon was kind of scared now. He had just given his little sister complete control over the movement of his body.
"Wow! I wonder what else I can do..."
