a pretty good website for free audio files is :
https://www.warpmymind.com/

membership is free, premium files are also free for those who submit a story and get it published, or upload original audio files for others to use. there are a lot of feminization files available on there, as well as regular files of all sorts.

there are also forums you can read (success stories is one of my fav.).
