So many pieces of smut are set in like, Fantasy World Where Everything Is Focused On Sex. Like, you know the drill, you take some guy's specific fetishes and mix it with a complete re-organizing of all of human society around sex so that whatever horny Thing they wanna write can just suddenly happen
but what if we already exist in one of those universes
what if this world is the way it is because of some guy in a higher dimension's specific fetishes. Is he just really into heterosexuality?
What if some higher dimensional mollusk thinks shells are super hot and we're just an incidental side effect?
