Royal Estrus

Luna goes to see Celestia and her husband during estrus. This is not a good idea.

Estrus is upon Equestria. It's a time of passion, of lust, and of discomfort and frustration. Luna has been around long enough to have done and see it all during this long, long month. Unfortunately for her, Celestia is going to try her hardest to show her something new.
