Fluttershy and Discord are expecting a foal; which means a few things in their lives need to change. For starters they need to make sure that their foal has a healthy birth despite a rather large complication.

Discord is filled to the brim with magic. Any child he conceives must be born of similar magic. Currently Fluttershy is not equipped to see the pregnancy to the desired outcome.
The solution must be born of Chaos. Are they prepared to do what it takes?
Is Fluttershy prepared to fully give herself to Chaos to start their family?

Sex tag: because sometimes one plus one adds up to three.
