Many erotic hypnotists have derived inspiration from fictional scenarios (many of the early hypnodom/mes got their early ideas from Erotic Mind Control Stories, which DOES have a lot of inspiration. I'm starting this thread to discuss fictional mind control scenarios that might be worked into hypnotic trances. I'm gong to start out with a few created by psychologist William Moulton Marston, which he used in his Wonder Woman series back in the 1940's.
The Magic Lasso: Long before writers started calling it "The Lasso of Truth", probably to keep the BDSM implications away, forcing someone to tell the truth was just a secondary part of this. If you were bound by the Magic Lasso, even loosely, and someone was holding the other end, you could not escape, and you were compelled to obey any command the holder gave you, including but by no means limited to answering questions truthfully, although a command to tell the truth might have been necessary; it was hard to tell from the text. A feature of this is that being compelled to obey the command did not include a desire to obey the command, so that person bound might be able to figure out how to take advantage of the wording of the command to get out of it. Still, the idea of involuntarily being forced to do something has its charms.
The Brainwashing Booth: It was a booth you sat in (very much like a "sit down" videogame in format). You are bound to the chair, and your eyelids taped so they can't shut. You are subjected to flashing lights and sounds (with a meter showing your resistance level, so they can be adjusted just for you). In front of you is a picture of a person. That picture becomes burned onto your mind; when it is finished, you still have all your faculties and abilities, but that person's picture is burned onto your mind, to the point where your primary motivation in life is to serve that person. Any other consideration is secondary.
The Venus Girdle: This takes the Magic Lasso one step farther. When enclosed in the Venus Girdle, you not only have to obey any command ANYBODY gives to you, but you WANT to do it. Not only can't you break out, it takes a tremendous amount of willpower to even want to break out. You have very little volition of your own; your sole purpose and greatest joy is to be commanded and do what you are commanded to do. Essentially, you turn completely submissive and obedient. There was one scene in particular from the story, "Villainy, Inc." which shows Amazon guards being overpowered by the villains, having Venus girdles put on them while they're struggling, and, in the next scene, submissively following the commands of the villains.
