Do you think CC needs to manually connect herself to her whole body or is simply having her head on her shoulders enough?
It would be funny if CC went on a mission to catch Shiori while GG stayed behind and decided to clean up her old spare parts she found in the basement ("she'll be so happy when she comes back"), but CC still felt everything she does to them because she forgot to sever the connection, all while being unable to abandon her mission.
It starts as mostly just tickling and poking, but then GG starts feeling frisky and oversteps her boundaries right when CC is about to confront Shiori, exploring more private areas and practicing kissing with a spare head. Shiori takes advantage of this to tease the doll for a good laugh, further humiliating her.
When CC comes back, GG greets her and presents her squeaky-clean spares, but the former is completely fried from the experience and can't even get mad at her.
"Must have been a rough day, huh?"
