A few months ago, Princess Luna announced a new government program: the Batpony Repopulation, Education, Acclimation, Socialization, and Training System. This ambitious, decades-long project is dedicated to restoring the batponies (recently declared endangered) to a healthy population. In order to generate public interest, Luna has personally volunteered to go through the program, showing that anypony, regardless of social status, can assist in this endeavor should they be able.

To this end, Princess Luna has become pregnant with a brood of burgeoning baby batponies.

Her pregnancy has gone along smoothly for the most part, but the changes in her hormones have made her rather... antsy. And worse yet, she hasn't been able to find any relief due to being so busy all the time. She knows that she's going to snap if she doesn't do something soon, but her family and advisers have been annoyingly obstinate on the matter.

And that's when he showed up.
