Of course

You whisper to the doll "You will stand still no matter what happens" as you finish she freezes in place

"What do you do to me?" She asks straining to move

You don't care to answer, but instead continue to take one of the needles out of the doll and poke it into her back, a piece of thread coming with it. The needle instantly disappears and now the doll and your sister are connected by a single thread. You pull at the doll to see if the string will go taught, and the string vanishes, remembering from the manual you easily figure out that the string is still connected just not physically until you want it to appear again.

You laugh a bit, you know you have your sister under your full control, there is no command she won't follow within reason of course.

"You prefer to walk around without clothes" you say

"Of course master" she says still unmoving

"Oh and you can move"

You see her body relax she then continues to the vanity to start applying makeup, no longer having a need for clothes

"Nice, this is gonna be sick. And I haven't even puppeteered anyone yet" you say as a idea comes to mind
