I spent a lot of time bouncing back and forth between what color to do her nipples and ladybits. In the end I felt an olive green was the best, though pink and a lime green were also options I experimented with.
I like giving our goth babes piercings and haven't given any clit jewelry yet, I think Shego is an appropriate first for that piercing. Still waiting for the right lady to pop up to go all out and do tongue, nips, and clit all together! Maybe Mavis?
