Does anyone remember the name of that vore story that has a brother and a sister that were going to be married? In the story, in order to please the fertility goddess, the sister needed to have sex with her brother, and then devour him alive orally, and from their offspring, it was supposed to bring their town prosperity? The mother in the story helps tie the girl's brother up, the boy's grandmother frowns at him as he'd being hoisted up onto the stage, the 'execution' is being done publicly, and everyone's laughing at the reaction the prey, sister's brother, has. The prey in this story is very resistant throughout all of it. The word 'Sibling rivalry', keeps popping back up into my mind, but I know that's not that name of the story. I don't remember if the story was on Eka or Giantess City... the two are of age, just having turned eighteen I believe, and in the story, the boy has come of age, and like a punch in the gut, everything is revealed to him on the stage, and it's happening surreal. The method of vore the girl uses on her brother is oral vore, feet first, because I remember her swallowing his head last.
