Happy Sacked Android 18 WIP1 (Pixiv Fanbox)

A project I'm doing for Halloween! The Happy Sack concept was created by Bastianmage\Madpuffins. It's a living suit that forces itself on an unsuspecting victim and makes them smile and masturbate against their will, until it's somehow removed. But it looks like Android 18 isn't being freed anytime soon. These are test images to see if I could accurately recreate the sack, and now that I'm happy with how it looks, I can work on the image set. The background might change.
