Had to remind myself that this is a bondage story…
I consider that Empusa’s use of magic is an analog of using AI to create images. She can create a prompt that describes what she wants, but the results are not yet quite good enough.
Sometimes I consider magical bondage as “having gone too far”. That is, it becomes so outlandish that it is no longer erotic. So, I am treading in a danger zone, I suppose, of “going too far”. It’s a strange notion… bondage. Hopefully, this is still erotic for the readers.
