Fluttershy lacked confidence, Luna knew this and also knew she wouldn't be able to boost her confidence in the real world, so decided to help her in the dream world instead. What Luna didn't foresee was that the confidence lessons would soon be replaced with lots of kinky dom/sub sex dreams.

This story has intentionally not been written very well in terms of structure or characterization, the point of the story is that it's meant to be so bad it's funny. If you think it's just plain bad, that's cool too! :P
