I wanted to post this in the Worldbuilding Made Easy thread but it died before I got home so I'm posting it here instead. I don't really have a political power fantasy so I focused mostly on my fetish, that being nasty bitches with fat cocks, with a little bit of the esoteric magic thrown in for fun. Here's what I've got so far.
>The premise
Basically Futanari exist, not only as a rare third gender that is functionally both male and female, but as the chosen people of the primordial Rebis who represent the union of opposites. At the dawn of time all living things were Futanari until the Rebis, the hermaphroditic creator god/dess, was forced to split itself into multiple parts, separating the divine masculine and feminine principles from one another. This act upset the balance of the world, creating strife and limitation, the surviving Futas were tasked with becoming the guardians and guides of the rest of humanity so that they can eventually reform the Rebis, but opinions vary on how this could be achieved.
>How do Futas work?
All Futanari possess functional male and female genitalia with balls because a futa without balls is a crime against humanity and can reproduce with both men and women, Futas actually differ depending on how they were conceived, favouring Lingam or Yoni (these will be explained later) based on their non-Futanari parent. Two Futas may also reproduce but the offspring will be infertile, it is believed that this is to prevent Futas from abandoning their birthright to live apart from normal men and women, the children of two Futanari are variously pitied or looked down on as burdens by their true breeding kin.
