Preferably female only, or at least a female hypnotist. And if it includes lesbianization too, would love that especially!

This is the closest I've got to matching the criteria. Unfortunately, only a small part in the beginning that matches the stage hypnosis part of the request. Matches the rest of the requirements though.
