Add a receiver to her neck

You reach over to Carrie and stick two small receivers at the base of her neck on the backside. They light up to show they're attached before turning back off.

"What do those do?" Carrie asked as she reached back to feel them.

"They do what I said they'd do, let me control your body. Also could make some mind changes and stuff like that," you explain as you pull up the program and get it started. "Nervous?"

"A bit. Not every day you give up control of your body," Carrie laughs light-heartedly. "What all do you plan to make me do?"

"You'll have to find out," you say with a wry smile as you attacher a small dot right beloe your left ear. "Alright gonna sync it now. You sure you're okay with this?"

Carrie thought for a moment and then nodded her head.

"I did say anything. Lets do it," Carrie smiled.

"Alright, you may feel a slight sting. Don't move while I sync this," and with that you started the sync.

At first nothing happened. You both waited as the computer ran through lines of code. Finally after almost a minute had passed, you felt the sting in your neck. It was slight, as if somebody had given you quite a zap of static. Carrie visibly winced then after that seemed fine. With that, the computer said the sync was successful.

"And thats it," you said, looking over snd smiling.

"I don't feel any different," Carrie said, looking at her hands and around the room. "I can still move just fine."

"Well, lets test it out," you say, excited to see it in action. "Try to hold your hands out in front of you."

With a mere thought, Carrie's arms went limp at her sides. You'd taken away the use of her limbs. Carrie tried to move them as her eyes grew wide.

"I cant move my arms or even my legs," Carrie exclaimed.

"I know but I can," and with that you moved them with your mind.

Carrie's arms sprang to life, fondling her tits and feeling her legs. You also had her uncross her legs, now having them sit side by side. Carrie's look of amazement was something else.

"My god this is so hot, I can't move at all," she said.

You concentrate on her voice and keep smiling while your girlfriend gropes herself across from you.

"I can't use my voice now either. I'm basically just a puppet," you **** her to say. "Don't worry though Carrie, you can sit back and enjoy."

With Carrie's body under your control, you now could do whatever you liked as Carrie was a passenger trapped in her own body.
