"You hold in your hands the Miraculous What If Machine. It has the ability to transport you to any of the infinite universes in the multiverse. Think about it. Every choice you have ever made has spawned a new reality. Every choice EVERYONE has EVER made formed an individual separate reality, creating an unfathomable number of possibilities. Every conceivable and many inconceivable permutations of your life exists somewhere out there. Perhaps in one of these exists a life where you are happy. To go there all you have to do is ask: what if...?"

People begin receiving a strange device in the mail. A device that prompts them to ask "What if...?" and then whisks them away to an alternate reality where their statement is true. The device is never wrong, yet never quite matches the user's intent either. One could even speculate that there's a sinister and lewd consciousness lurking within The Miraculous What If Machine.

This is a series of very smutty one-shot stories (And although I say "one-shot," they'll each be a few chapters long, so I'm lying).

Although, some may recognize the phrase "What if...?" and the term "multiverse" as being associated with Marvel. This is not fanfic and does not take place in the Marvel Universe in anyway whatsoever. I've only taken inspiration from the core concept: ask what if, and then see the universe where it is the case.

Final disclaimer: since the stories won't be all the same, the genre's and tags are incomplete and only indicate the most general themes. I'll provide a more complete list of content at the beginning of each story. But expect plenty of genderbending, feminization, sapphic sex, and characters in awkwardly lewd situations.
