Sunset Shimmer visits Equestria and spends some time taking care of animals with Fluttershy and Rainbow Dash.

Rainbow Dash is apparently not good with certain animals.

Sunset discovers very quickly that what you learn from the human world cannot be unlearned, ever.

Rated Teen and Sex for a pile of juvenile innuendo, though technically no bad language. Only technically.

If there was one thing Twilight Sparkle had learned since ascending to alicornhood and becoming a princess, it was that ponies talked. Then, quite suddenly, they were talking about her.

And then they were talking about her love life since she was a single princess, unmarried and approachable.

She was still getting used to that part.

She was especially getting used to talking about it with Sunset.

Please see title. Or, alternatively: everypony in Equestria wakes up gay and must deal with the devastating consequences. There, I hope that explained a bit more.

Seriously, that's it. Succinct is my middle name! (Actually, I kinda wish it was. That would be so cool.)

Now, the idea of seeing someone argue who was the "best Princess" in Equestria was hardly a new thing. In fact, such talks had appeared in articles across Equestria for some years now. And every Princess knew what it meant when another one turned up. They'd read it, they'd have a debate amongst themselves over what was said, they'd maybe argue, and then they'd laugh over it afterwards. But today, they come across one such article that causes no argument. In fact, it genuinely surprises them.

Celestia thought she knew her sister. She was sure that nothing could surprise her anymore. She was certain that there was nothing more that Luna could possibly be hiding from her.
One attempt to identify a changeling presence in the royal guard later, she was coming to terms with how reality had decided to prove her wrong.

From father to son to grandson to great-grandson, on and on down through the centuries, Celestia has continually found love and comfort from a singular line of remarkable stallions. For a thousand years, she has been romanced and bedded by a succession of lovers from what may very well be the most charming, suave bloodline to ever exist.

Then Luna returned from the moon...

Chrysalis' scheme has borne fruit. United by bribes and promises, the leaders of each nation have come with her to deliver an ultimatum: surrender Equestria, or face hopeless war with their combined armies.

So why does Celestia look to Chrysalis with a gentle, mourning gaze? And why is Chrysalis afraid?

Twilight Sparkle wakes up to an unexpected thought, and now she just wants it to go away. The idea is embarrassing enough: an erotic liaison between herself and Princess Luna. But Twilight's problem runs deeper. She can't ignore this idea, however much she tries. She decides to write it out as a story, to clear the thing from her mind. Now she needs to finish her story quickly – because if she falls asleep before it's done, the Princess of Dreams will get to see that idea for herself.
