For a more serious NSFW AU, see Underlust.

Under(her)tail is an NSFW AU with a more comedic tone than Underlust. Under(her)tail is Undertale meets Monster-girls... and one Human boy, of course. A silly idea for a porn parody based off the popular indie game except all the Monsters are sexy ladies.


Due to Under(her)tail containing nudity in just about every page, no direct link to the pages will be provided.
