I need your advice. I am making a big anime coloring book project, but I'm not sure which 'fetish' is more popular:
1.) Sexy office colleague fantasy
or
2.) foot fetish.

What do you think?

This isnt really my kind of subject sadly, but if you are posing this question just to hear others opinions rather than a straight clear cut answer, I would think office is more popular. As much as i know foot fetish is a thing, maybe mire so than offive idk, if you are going to make a colouring book from it i would like to think that you can include so much more doing office theme
