I wondered the same thing and wrote to EMG to ask. He said that as part of a set, no, it's not available as a single file.
This, I think, is a real shame.. I'd like to at least hear it, but I have no need of the other files in the set, so can't justify spending $30 for just the one file.
This is a VERY good induction for those who are into the diaper and infantilism "scene".
I've responded well to EMG's various inductions that I've listened to over the past few years, but I have to say that I went down into trance in what seems to be a much faster (but VERY 'gentle') way.
Miss Shelley it is a shame that You have no need for the other files. I'll say that the set is worth the price, especially with this new induction.
stevec, I'm not sure what you're "into", but if you're interested in the induction I would definitely recommend purchasing the set.
