I have played this with the hypnosis fetish people. It can be extremely fun, and I honestly didn't believe that it would really work at all. I played with a guy called Lex who was the best. He has a couple of YouTube channels I think. I never played on camera, and it was over text or the phone. I had no idea that you could be hypnotised this way, but yes.
With hypnosis kink, instead of Ler and Lee, there are tists and subs. I thought that subs was short for submissive, but it's short for subject.
I turned out to be a good subject. You need to be submissive and suggestible, and be in the frame of mind that you want to go along with it. Alot of hypnosis is self hypnosis I was told. You need a good imagination and to be able to visualise.
Tickling wasn't the only thing, and you can be bound with hypnosis. He could tell me that my feet were bound, and then I physically couldn't move them until he "released" me.
Some triggers are still there, which is fun when I play with my partner.
Find a good, trustworthy tist when playing, because as with all kinks, you get your perverts and weirdos. It's a huge no no in the tist community to "drop" people with out their consent. As in dropping into hypnosis. It's also good for them to end the session with the sub feeling safe, happy and all triggers removed unless they want any to remain.
It was fun. I haven't played in a while, but I enjoyed it at the time. Lex has quite a bit of tickling in his hypnosis videos. They were on YouTube. Not sure if they're still there. I remember reading that one of the first hypnosis sessions he did, was when he made his extremely ticklish friend not ticklish at all.
