Using the Anal Whore Hypno from Goddess Lycia is delicious. It starts out with normal induction and trust to the hypnotist. Then it takes a "nice" twist with Small Penis Humiliation and Laughter at the listerners small "penis" and negates any other option then to cum from anal. It is really a treat to listen to it. I had a spontanous non-orgasmic emission 4 days ago during listening and since then I am unable to masturbate to an orgasm anymore. Saying that, I had similar experiences before, that it seemed to work only to fail after some time again. But as a nice little treat I think it is delicious.
I find that one-on-one hypnosis leads to even more dramatic results... recordings don't do much for me.
