unscensored AI chatbot

I want to create a website like https://www.dreampress.ai/ but better I want to be able to create stories as good or even better than the popular ones on https://www.sexstories.com/, as I want to allow users to add their preferred characters and to be able to enter a prompt and the ai will create an in-depth story for them, Ideally I would asl have an ai voice narrating the story

Do you know if there are any ungated LLMs fully uncensored and permission-less, basically llms you can run on your computer that are good at generating text
Also would it be possible to train these models
