Install text-generation-webui (aka "ooba"), use it to download a good model which your CPU or GPU can handle (e.g. TheBloke/MythoMax-L2-Kimiko-v2-13B-GGUF
), install sillytavern and configure it to use your ooba, then get some nice character cards from chub.
(or directly use the ooba webinterface to tell the AI to write a hot story)
I can go into further details if you are interested :)
pro-tip: If you find a good, long story that you like, put it on your ebook-reader (Calibre will automatically convert HTML to whatever format your device wants). Ebook-reader in one hand frees up the other one...
