When Discord is having afternoon tea with Fluttershy, he noses around and discovers some large adult diapers. His first assumption about them, though, might not be correct.
Fluttershy doesn't actually think of using the diapers herself. What she likes the idea of is taking care of somepony else - and once he hears that, Discord is only too happy to provide somepony else for her to take care of.

This story is done for https://www.furaffinity.net/user/randommutationromances/, who also provided the cover art as part of a trade. His OC has a major role in the story.

Contains diapers, plush suits, petplay themes, hypnosis (consensual) in later chapters.
