I've had a really severe hypnosis fetish for 20+ years, to the point that my first orgasm was to the idea of hypnotizing a group of people, with sex stuff only implied.

One one level, it's just forced sex without physical force. So you get to fantasize about getting taken by someone you don't want, but then loving it and having a great time, or you get to imagine having absolute power over someone unwilling, but without violence or emotional ugliness. Basically, the fun of something incredibly immoral without the typical horror that comes with it.

But then there's another layer to it: the mind is the most erogenous organ, and is totally sovereign; it can be manipulated, but not forced. IRL it's more or less impossible to force a mind to think something; the thrill of being able to do that, or of having it done to you, is just insanely delicious. It's an absolute form of dominance; there are many, many, many dimensions to it that get me off in all sorts of ways.

>getting persuaded that something erotic is a social norm and putting up with it on that basis
>controlling an entire group and creating a sort of artificial microculture (such as a cult of people that worship your cock)
>getting controlled without your knowledge, having your memories edited
>teasing someone by giving them awareness back only to tell them that you're going to erase their memories of the hypnosis
>not only doing, but believing insanely humiliating things
>having your likes and dislikes tinkered with while you're fully aware of it: "Hey, I'm going to make you love sucking balls, okay?", getting upset, protesting, hearing the finger snap, and the lovely moment of being overcome, you helpless ballsucker
>trigger words that can drop you in the middle of a conversation
>compelling sensory hallucinations; making someone squeal and cum hands-free to something that isn't happening
>the unfairness instant hypnosis
>the seduction of slow hypnosis
>subliminals
>instant orgasm commands
