As I understand it, no one understood what
jonbox meant, here we are not talking about detailed elaboration of the penis, their different types, length, physics, etc. But just so that at least the skin moves back and forth, not an expert in animation, but I am sure that it will be tens of times easier to implement than the same breast animation. I did not look closely, but now I noticed that it looks really very static, especially against the background of such lively boobs.
It's funny by the way that I had a couple of questions regarding Kitty, but the most important one for me was ignored by everyone, and not particularly important ones were discussed on two pages :3
I am talking about the tilt of the head. I am not against the fact that most girls have a tilt, maybe you decided to make them more alive, or for some other reasons, but doesn't it seem that Kitty's tilt is just too much? I can say the same about Rogue, the others seem to be fine.
