Can she shapeshift between these different forms?

Hmmmm, is this a trap....

Naah, I don't think so. *Reaches in.*

(Haphazardly thrown together demo for scale) #vore
You're *absolutely* welcome to! though... it's gonna be hard to reach without leaning alllll the way in. and it's much closer to shoulder diameter than it is arm diameter......
You *may* end up with more than just your arm in there in short order.

Interesting.

I know you said her animal forms were non-canon. But, canonically, can she change between her anthro and regular form at will?

The dark atmosphere makes it look a lot better.

I wonder how much they enjoy it too.

Very big, how much can he fit inside his belly?
