Also known as, the Twilight.
I feel like this story doesn't need much of a description. After DJ Valkyri-3 I wanted to write more cutesy romance and see if I couldn't squirm my way back into ponified. Saw the picture and, well, this happened.
Also, I never really see Twilestia from Celestia's point of view. It's always form Twilight's or an omniscient view so I thought I'd try it out. Turns out it's really fun to write!
Enjoy!

Added the sex tag for chapter 2 specifically, but unless insinuations without real descriptions and raunchiness with a dose of lewd iconography rubs you the wrong way then it's perfectly safe. It's still nowhere near needing the mature tag.
