Though the other option is just being an obedient doll who obeys any command given to them by anyone, so it's really up to you which you prefer~

Though that'll just be normal after a while, identities mingling and homogenizing amongst a group of doll sisters, even if they feed on enough humanity to stay individual for the most part the homogenization is inevitable~

And if you do avoid consuming or fail to keep well fed (common with how much of a vicious cycle stillness creeping over you can be) then your sister can just press its lips to your own and feed you enough to make you move again, though its thoughts may be mingling with your own for a bit.

so long as you keep consuming enough humanity to keep from lapsing fully into obedient stillness, though you'll never be able to drain enough to regain your own humanity, since that's already been consumed by your cute sister when you turned~

f they take it all though, well, eternal life as a pretty dress wearing gothic doll girl with your new sisters wouldn't be that bad,

Well could you at least mix some helium in so reaching the top ones is easier?

Heyyyy, I think I recognize that line >:)
