You can find a chastity hypnosis audio file here: http://sites.google.com/site/goodsissy/home/files/CBHypnosis.mp3 . It's a female voice convincing you that you want to stay locked in your chastity tube. Tip: put it on your mp3 player. I found the original voice in a youtube video. That one is made for chastity belts. As I'm in a CB-3000, I made this remix version for chastity tubes. The text is actually based on a post on Altairboy's site.
