Mother of Beastmen!

She rewards the Beastmen race with endowments to their cocks and libido as well as removing their hatred of civilisation, replacing it with the love of warm bodies to fuck and an insatiable appetite for sociality. If these little furry bastards were to be her sons, they are going to be at least approachable. Their musk turned up in potency to attract more feral creatures, like Skaven and Harpies.

She redesigns their behaviour so that they are fine and even encouraged to fuck mortals like the humans and elves, even the Slaan if they're fuckable. Centigors, Minotaurs, Gors, Ungors and by extension the Harpies shall all be fuck gods, just like her! She masturbates as she imagines many different orgies with her children.

She did not forget the Beastman who started all of this, Bruan Ironhoof. She gifts him a second member below his own and the ability to control them like tentacles for easier fucking and breeding. She will want Lileath in her chambers, but sending a replacement toy is not out of the question. Last of course would be a Mark of Slaanesh, can't be a Son of Slaanesh without a Mark on the balls!
