Kind of a special case since those are from kagura games.
Kagura games sells games on their store and on steam but on steam they have all the adult content removed (to the point that many of their games don't work and crash) and you have to download the patch from kagura games website to add the adult content once again.
I am not entirely sure if this game can do the same and just remove all animations and adult themes and have a patch you have to download outside of steam and install so the game actually works
