..For those into forced feminization but don't want to go to the extent of real changes.

The first file is the basic introduction to the hypnotist and the second is named "Jessica", which makes you feel and see yourself as a female in trance (And also makes you orgasm close to the end of the file, according to reviewers).
I'm still trying to make the Jessica file work fully (One time I felt breasts and I was lucky enough not to get an erection during the file, so I felt close to having a pussy).
It also installs 2 triggers, I can't really put them in detail. I haven't gotten them to work too well for me, so I decided to post it up here in hopes that someone might have a better chance at getting it to work than I.
Good luck.
