My name's Rainbow Dash. I'm Equestria's fastest pegasus, I'm the Element of Loyalty, I've saved the whole kingdom more than once, I've laughed in the face of danger, and I'm a coward. That's right, I said it. I'm a coward. I've always been sure I could do anything. Win any race, beat any opponent, complete any job. But this is something I can't outrun, outsmart, or outlast. What's causing me—the most awesome pegasus ever—so much trouble? You wouldn't believe me if I told you.

Every week or so, Rarity gathers all of her friends for a little get-together at her boutique. Or at a cafe. Or in Sugarcube Corner. Anywhere that serves tea or tea can be brought in.

And every time, as soon as their conversation steers towards that most intimate of topics, Rainbow Dash falls silent.

Twilight Sparkle wakes up one morning to find she's undergone some changes. She shortly discovers she wasn't the only one. (New cover art by Jamey4 on deviantart http://jamey4.deviantart.com/)

Warning, this work of fiction contains multiple fourth wall breaks, massive silliness, and more than a trace amount of alicorns.
The author may or may not have snapped at times in the writing of this work, and it shows. Bring a towel, you may get wet.

After Twilight Sparkle discovers a new book of pick-up-lines, she wants to bring her friends closer by complimenting them with cheesy lines.

And it does more than bring them closer...

This story is a sequel to The Three Sisters

What if... After "The Three Sisters" Rarity managed to find Chrysalis and talk to her?

A definite sequel.

Now with a TV Tropes page! Warning: will contain spoilers.

Mood Wings - Observations on Pegasus Body Language.

When Twilight Sparkle finds this book, she discovers an entirely new field of research. The secrets of pegasus wings lie before her, and she insists on making her own observations on the matter.

How?

Field research, of course.

In an effort to keep her mind occupied, Twilight Sparkle decides to delve once again into the grand mysteries of Pinkie Pie. This time, Twilight's focus is on her claims of growing up on a rock farm: like so many things related to Pinkie Pie, the idea that somepony could grow rocks as an agricultural product makes absolutely no sense. However, the investigation eventually leads Twilight to a rather... surprising discovery.

This is the first story in The Petriculture Cycle.

After her complete defeat at the royal wedding, Celestia's ego is shattered. Luna promises to whip her sister back into shape, because it'll take far more than a few laps around the palace to put a grown alicorn at the top of her game. But, with Celestia coming home each day with a new set of bruises and a slightly more forward royal attitude, her subjects begin to fear her more than love her. Is Luna's

special training turning her into a monster, or is it all according to some greater plan? It's time for some tough love!

(Warning: Dark tag for some Celestia abuse.)
(Featured 6/19/2012! :D)

Twilight Sparkle just can't find enough time in the day. She has to study friendship for the Princess, hang out with her five friends, and juggle her own hobbies and interests besides. But when a novel solution presents itself in the form of an experimental new spell, will it solve her time crunch, or will she be distracted even further?

Inspired by Friendship with Benefits is Magic. Not intended as a direct followup as much as my own take on the idea. What is Celestia to do when Twilight Sparkle shares a little too much? And why doesn't Twilight have any idea what she's talking about? And why is Luna smiling so much!?

Followed up by yet another epistolary conversation between Twilight and Celestia about the magic of not knowing what the hay that other pony is talking about. Features a special guest appearance by naughty!Luna.

Further bulletins as events warrant.
