Celestia's morning has been difficult enough, between hearing Twilight's confession of love, and then breaking her heart as gently as possible. Mere moments later, her private chambers are rocked by the shockwaves of a time-traveling spell. This marks the arrival of Celestia's alleged lover from five thousand years in the future, Princess Twilight Sparkle—or as she insists on Celestia referring to her, Glitter-Flanks.

Armed with thousands of years of knowledge of which buttons to push and how to make her squirm, Glitter-Flanks has traveled back to this date for one singular purpose: to establish the closed time loop that sets the two of them up as a couple.

Twilight Sparkle has always loved Celestia—as a friend, and a mentor, and something else as well. And she finally, finally found the courage to admit those feelings.

Celestia turned her down as gently as she could. That's what she thought, anyway.

But the night is still young—and it's a night for being wrong.

[Rated T for suggestive sexual content. This story takes place between the Season 2 and 3 finales. Additionally, I wasn't able to find the artist who did the cover art, if anyone knows please drop me a line so I can credit them.]

While sharing an intimate moment, Celestia and Twilight Sparkle have a little chat.

This story is a sequel to Growing Pains

After a magical mishap involving a filly, magical empowerment, and an aging spell, Twilight finds herself stuck with a rather large problem.

When Princess Celestia shows up to help her out however, it becomes apparent that Twilight isn't the only one affected by her new looks. Which in turn brings back feelings she had long thought forgotten.

Reading the prequel to this story is not required though it does help.

Enjoy.

Twilight Sparkle wants to reestablish her old rapport with Princess Celestia - the close relationship they had when Twilight was the Princess’s personal student. But life moves ever onward and the connections they had in the past will not be enough for the alicorns to overcome the challenges that lie ahead. To make it through their shared trials and revelations, Twilight and Celestia will need to grow beyond their existing bonds and become much more than faithful student and immortal mentor.

Hearts and Hooves Day fast approaches. For Twilight, her friends are shocked to learn she's never had a date. For Celestia, Luna reminds her that she's not had a date in, well, a time period she would rather not get in to. Luna conspires to push the two princesses together. Will a so-called "practice date" turn into something more?

Now with a sneaky little interquel in the form of Celestia Wants To Do Naughty Things To Twilight Sparkle. A mature treat for those who like that!

Took second place in the Fifth Bimonthly Twilestia Contest.

Being an alicorn is wonderful... except when it isn't. There are plenty of things that put a damper on limitless vistas of possibility afforded by such a long life: Court, mortal needs and expectations, the occasional decade of ennui.

And the dreams, of course. Agelessness comes with its own special kind of dreaming. Celestia finds that her own "Inner Court" is a bit too literal, and it--and she--are troubled at the prospect of a near-immortal Twilight Sparkle.

If only she could articulate exactly why that was.

Part of the Monophysite Quartet, which also includes Celestia Isn't Real, Have You Considered My Servant, Twilight?, and The Esoteric Rites of Darkness. All four stories have a common origin point in an old story idea I called "Monophysite" and touch on who or what Celestia really is in some way. They are otherwise unrelated.
