Write it and find out...
I ended up writing and posting the first chapter of this story idea about the Mandela Effect - Incest In Another Dimension - the other day. It was a 10 page first chapter, with smaller chapters to follow in coming months.
The IT readers though haven't seemed to have really gone for the story, it has only about 5000 views since it was posted mid-week, few votes and a low score, 2 comments 1 positive and the other mostly negative.
Maybe they aren't too keen on other-worldly or sci-fi and fantasy in this category? Another story I wrote in this category last year - Bigfoot In the Bennington Triangle - also sank without trace. One I wrote a few years ago about stepsiblings in a haunted house did okay scores wise, but didn't have high views. And while a body swap story series I wrote in 2019 was hated by readers, at least it got some attention if mainly all negative.
It's strange how some people are obsessed by tentacle monsters and the like, but erotic horror, science fiction and fantasy stories even if they have a real world setting like all of mine, don't seem to attract much interest.
