I think if I was gonna want a global effect for the hypnosis/mc kink, I'd prefer it to just be the introduction of various forms of hypnosis and mind control into existence. Some people can speak people into compliance, some have entrancing eyes. Control through playing music, hypnotic tattoos, physical touch, magic spells, technology, titnosis, cocknosis, the whole gamut.
Not everybody would have an ability, but it would be widespread enough for their to be a whole secret community around it.
I'm also a switch so I wouldn't want just women as the subjects. For the most part this community of controllers would just take their pleasure by controlling and corrupting "normal" people. But some would look for the more dangerous game of trying to enthrall other controllers.
Of course, the other controllers can fight back, if they aren't caught by surprise. But if it happens, their reach can spread exponentially. High risk high reward.
Of course if it gets found out that a controller is amassing too much power, the rest of the community comes together to sort them out.
But for individual battles it's more dog eat dog. Either you can fight off and subdue another controller, or you're subdued.
Probably some abilities have better and worse matchups. Someone who controls via speech might have an easier time against someone who controls by locking eyes. Or someone who uses titnosis could catch an eye fixation user staring at their cleavage.
But then maybe eye fixation could work through cameras, or from a farther distance.
So it's just a world where normal people are playthings for superhumans who all have various means to compel people. And sometimes you have those superhumans going after each other. That'd be a fun scenario. For some people.
