Ella Enchanting
Ella Enchanting has been doing hypnosis for quite a while, doing hypnokink for a few years, and doing D/s-ey hypnokink for a bit less time than that.
She identifies as a very switchy switch who loves to geek out about all aspects of hypnosis and will always respect your argument more if you bring the appropriate citations. She knows many things about hypnosis. Some of them are probably true.
Ella records hypnosis files, writes hypnokinky stories, and has some fantastic educational content up on her Linktree.
