I'm sorry, I didn't know you were asking for a single search term to put into google to find more of this incredibly niche type of fantasy fetish porn. My crystal ball must have been turned off. Anything else you were thinking but didn't type that I failed to pick up on?
Maybe try putting some of the existing images into Tineye, IQDB, or SauceNao and seeing if they link back to e.g. a particular Pixiv post, then run an auto-translate on it to see if any of the tags turn out to mean "Recursive" or something similar in English, then click on the matching link if so? And copy the original kanji to use for wider searches?
Maybe use your brain and also communicate in complete sentences rather than just grunting in the general direction of the internet and expecting us to know the exact nuances of your eight poorly-formed words were meant to be?
