They are very compatible with tentacles and monsters.
I especially like futanari
A certain shrine maiden fought and exterminated the sealed evil spirit, butThe evil spirit had left a seed inside her...The grown-up evil spirit parasitizes her crotch and turns her into a futanari, controlling her consciousness, ****** her fellow shrine maidens one by one, planting seeds, turning her into the same futanari, and controlling her...I admire the story
