I have a Bunch of Toilet Art Suggestions that I've been keeping on hand just in case someone's willing to draw them. Here's one to start.
Suggestion 1: Yayoi Kunizuka, dressed in the outfit in this image.
She's in a Bathroom Stall / Toilet Cubicle, sitting on the Toilet, with her Pants pulled down to around her Ankles.

I plan on sending more later, over time. It's OK if you don't draw any of them. I just thought it wouldn't hurt to ask.
At any time, feel free to ask for Details and Image References if you want. I'll try to give you freedom with how to Draw my Suggestions.
