Cuckolded by goblins
I have an idea for a story involving a small farming family set in some fantasy world akin to that of Middle-Earth. Said family lives very far away from the rest of the village is consequnelty menaced by goblins and other nasties whick keep raiding it for livestock and crops. So far, the goblins have not harmed the young peasant couple of their two children but the parents have become increasingly concerned that their kids might be carried off by the goblins and eaten.
One day, the goblins make a deal with the couple. If the husband is willing to let the chief of the little green nasties have their way with his lovely young wife, his farm will be spared and further ravages and his children will be left unharmed. Eventually, what was initially an unpeasant imposition becomes a source of pleasure for the wife and she becomes the goblin cheif's favorite wife, birthing a new , mixed goblin-human hybrid community. Is this an idea that would appeal to anyone into erotica set in classic fantasy settings? Thanks for reading this.
