I made one for inducing Lactation (may not work or be very good, but still):

You Must Lactate: http://hypno.is-best.net/N6iuw/

EDIT: The music isn't saved properly in the URL, you have to manually switch it. Idk, may be a bug.

i can't tell which one iked is referring to specifically with this post, but there are two penis shrinking files listed. Both are free, so you won't need to get a premium membership to download either or both of them. Shrinking Penis Training Loop V2 and Penis Shrink - Training Loop Hope this helps...

is it still available? the link doesn't go anywhere anymore.
