Hypnotic tickling
I've done a fair amount of hypnotic tickling, and my experience has been that it's success depends upon a number of factors including: depth of trance, how comfortable the subject is with both the suggestion and the hypnotist, the context (eg: where the hypnosis is being done, and how the suggestion is presented), and of course, how ticklish the girl is.
I've had girls literally rolling on the floor laughing uncontrollably after saying a trigger word that caused them to feel as though they were being tickled with a thousand feathers (they had no conscious memory of the suggestion); yet with a few other girls the suggestion barely raised a giggle. One girl told me she wasn’t that ticklish and only smiled and begged me to stop. Apparently for her tickling was more uncomfortable than laughter provoking. One girlfriend didn’t respond much to the “thousand feathers” but responded beautifully when I had her recall a time when a girlfriend of hers was tickled by two guys in college, then suggested that she was being tickled by them instead. Hypnosis does work, but it’s very situational and varies with both the individual and the circumstances.
