How do you "shake" her? I can poke(?) her, where I just click a part of her body and she moves slightly, but I cannot find any kind of way to actually move her body around, much less shake it.
There is no way to move her around. Personally I usually say 'shake' about jiggling the juicy parts during the main action. If you're referring to her phrases, 'shaking' probably means vibration.
