Still looking forward to liquids / oils.
Always interested in more panties and stockings options, or recolors of existing ones.
Maybe for a "spring 2020 / Social Distancing" update, add some panties with Hello Kitty a legally distinct cartoon character in a facemask printed on the butt. Also as a joke there could be a "use hand sanitizer" button that just makes a pump noise.
Have you ever considered a Multispanker Mode where you have two butts side by side to play with at the same time? Would have to add a menu option to pick skin/panty/stocking options for butt number two, but I think it sounds really fun!
Great game!
