I once interacted with justin, he came into a post I made years ago and just started talking about how he wanted to eat bird shit because he thought it would be sweet and tasty and how their high metabolism would turn food into shit very quickly or something like that. I think he was even talking about how it wouldn't technically be shit because it's like piss mixed in and how that might change the flavour. Idk what has to happen to you in life for you to get to that point but hey at least he's not settling for just any old dog shit on the streets, if you're going to be a shit fetishist at least have standards.
Also yea I'm late but you can already 100% do this already very easily. Go to any ai site that has user made loras or whatever their version is and search for scat/shit and vore you will get at least 100 different loras for it. Or go on character ai and search for reshiram and you can probably make it shit on you within two messages. I don't mind replacing fanartists and all that other shit with AI, I won't cry if artists become extinct professionally. But by god I will cry if justin starts using it, there's something special about his mspaint skills that no ai could ever hope to replicate.
