One thing I never understood is why the Doppleganger interactions only have an artwork when you're the one being fucked and not when you fuck it as well. I mean.... The outcome you get is literally the same, being you the fucker or the fucked one, since you're essentially fucking a clone of yourself, as well as the fact that the doppleganger happens to have the unique "feature" that either you end up being the "top" or the bottom in the interaction, you always both fuck and get fucked in those. Makes no sense to not share the artwork, but I guess is one of the style inconsistencies that this game has from a long while ago XD
