so, I'm working on a new manip, but not sure what's hypnotized her, so wondering if any ideas or even an image I could edit in to show how she's hypnotized?
The only way I could see that happening would be if the dom just happened to get really aroused by putting the sub under- Oh shit wait that's actually kinda hot to imagine.
I'd say it's a post-hyp suggestion, like "getting wet makes you wet." kinda thing. Although you might want to work on the wording of that now that I write it down.
