So I was thinking, and it would be a great idea to make a file where for 30 minutes after, your penis will be VERY flaccid. It will Become so soft that it is almost the size of a clit and may even shrink partially into the user's body so that only the head is showing. after the 30 minutes are up, the listener's penis/clit will be extremely sensitive for an additional half hour. Every touch will send a wave of pleasure through the user.
I would make this, as I have a fair mic, but my voice has a strange sort of accent to it. I would assume that that would impair the your ability to be hypnotized, but correct me if I am wrong.
