Kitsuika's Ninja Party by threk

An amazing absorption and partly unbirth story by threk on Aryion.   The story follows Kitsuika's four Ninja colleagues fulfilling their wish to be closer to their kitsune friend, so they won't leave her alone with her drastically extended lifespan. Luckily, they had recently learned of a special immortality ritual that, with some modifications, could be used to merge all four of them with Kitsuika… The end of this story focuses mainly on cock-vore, which is not really what I'm into, but the rest of the absorption and especially shared senses elements are awesome
