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.

It's the big day at last. The Wedding of Twilight Sparkle and Pinkie Pie, a match none saw coming. Pinkie Pie wants to make this wedding the best wedding there ever was in the history of weddings. She goes all out to make sure it's perfect just like it is. Except there is one surprise that not even she expected.

Her fiance, Twilight, wants to do the wedding reception aka Pinkie's favorite part. Pinkie, reluctantly, allows her and soon learns that a wedding isn't just your special day.

It's both of yours.

"I've missed you around here, Twilight."

Celestia loves Twilight, and she’s not afraid to show it. Or rather, she would show it, but she can’t. Twilight isn’t ready yet. She’s scared to tell anyone about their relationship. Celestia doesn't mind waiting. She’s a patient mare.

Celestia invites Twilight over for tea and chess. Things don't quite go as planned.

It is the first court session that three alicorns of Equestria will be holding together but Celestia has other plans for this court session that are less diplomatic and bit more scandalous.

This is my entry fer the TwiLestia contest, I hope you enjoy.

Twilight finds it a bit difficult to reconcile Celestia's playful new manner with the regal teacher she knew for so long.

Once she does, however, the benefits are plain to see.
