My fantasy world would be that of a whole community of FLR. Men would walk around plugged and caged with a collar displaying the name their leader chose.
I love the idea of being kept naked and being led around on a leash with my collar displaying my suitably degrading name. I’d be totally controlled by my mistress and denied any decision making rights. Eventually I’d loose nearly all of my intellect and would exist only to give her sexual pleasure. Women scientists would invent drugs to keep men perpetually erect and capable of multiple cum shots. Men would become a subclass of mindless fucktoys that are used, swapped and shared by their owners
