This story was written for Caladis for the 2023 Summer Sin Celebration.

Flurry Heart's first heat arrives and it's miserable. Her overprotective father, Shining Armor is distraught both by the event horizon of his daughter's adulthood and her fruitless search for relief. Feeling isolated and useless as Cadance shows Flurry the unforgiving ropes of royal marehood, he realizes that there is one thing he can do to help his daughter...

Things that Shining Armor will be defending to his wife:
Cheating
Incest
Foalcon (12 yo, whatever that means in Equestria)

This story now has a sequel.
