This story is a sequel to The Monster in the Twilight

Now that Luna has returned to the throne, and the aftermath of her brief appearance as Nightmare Moon is being cleaned up, the story is over. Right?

Not quite.

Twilight Sparkle had nearly been destroyed in the chaos of Nightmare Moon’s return, but now with the assistance of her five friends, she is facing a fascinating new world filled with wonderful things. No longer the scarred monster who nearly destroyed Canterlot and raged through the Everfree Forest for over a decade, now she has been healed by the Elements of Harmony and is living at the edge of town with her adoptive mother Zecora. Not all the fears of her past can be left behind that easily though, and now she must face the consequences of her actions as she faces the most daunting challenge of her life.

Ponyville.

Letters is a sequel to the alternate universe story The Monster in the Twilight. In this story, Twilight Sparkle exchanges letters with Princess Luna, two ponies with a common problem of fitting in and making friends after the destruction of Nightmare Moon.

Normally I would try to talk you into reading the sequel even if you haven’t read the original story, but in this case, you’ll probably be more confused than entertained. But go ahead. I don’t mind if you don’t read the first story. You’ll never find out what an Urlock is, but that’s fine. It’s your funeral.

Rated Teen just because of posting standards.
Rainbow Dash was on her way home from a great Wonderbolt show, but while stopping on a factory roof top to rest. Her curiosity however , soon gets the better of her upon noticing something from within. Needless to say, her being nosey gets her in some trouble.

Contains: Forced dressing, foal attire. Temporary dollified

After a thousand years, Luna is finally free from her torture of the Nightmare. Yet, even if she is no longer a monster, the common pony cannot seem to see her as anything but. Due to this, Luna is desperate to find something that she can use to start making herself appear as a more modern mare, something less out of legend and fear. A photo shoot seemed to be the best option, a chance to wear modern nightwear and show the world who she truly was. Unfortunately, nightwear has come to mean something else over the thousand years...

WARNING: Contains diapers and adult ponies wearing diapers, with suggestions of Adult Foal tendencies. If that is not your thing, then please do not read this story.

*Contains slight diaper usage*

Twilight Sparkle, as hungry for knowledge as the great unicorn mage Starswirl the Bearded, has created a portal to the multiverse, where endless wisdom awaits her. Excited, proud, and perhaps too tired to be thinking straight, Twilight jumps right into adventure! What does she find? Well, she certainly isn't too big for her britches... compared to the giant horses she meets, how could she be? Suddenly feeling pretty small, Twilight finds herself a foal for a night until she can find a way to prove she's intelligent. Well, it could be worse; at least these Big Horses make some pretty good parents.

Spitfire, Soarin and Fleetfoot have been working on a new trick called "The Triad Drive" A complex trick that not many trios of pegasi can accomplish. If not performed right, it can leave disastrous consequences on the performers. After the Triad Drive goes wrong, the three wonderbolts land safely as foals. The first one to notice this is Rainbow Dash, and she gladly decides to take care of them until a cure can be found/made. But when it's confirmed that there is no cure, Rainbow Dash will have to do the best she can on raising the three Wonderbolt Captains. Expect foalish fun and foalish things!

I'm sure you know this already, but i'll give a reminder:

WARNING! WARNING! WARNING!: This story contains diapers, breastfeeding and cuteness. Be sure you have no heart conditions that could prove fatal if you read. If this strays out of your comfort zone, do not read past this point. You have been warned.

Kudos to Aleximus Prime for the picture, and give my thanks to Equestria Daily's drawfriend compilation #991

THIS STORY HAS A SEQUEL!!! Be sure to check it out.

Sweetie Belle's birthday party had gone on without a hitch. Even with the presence of Diamond Tiara and her accomplice attending, things were pretty enjoyable. What made their attendance strange however was that Tiara had gotten her a present. Sweetie was hesitant to open it during the party, but once in the security of her bedroom she finds out what was truly inside.

Story contains, one diaper, pyjamas and sister bonding. No actual usage is present. Hardly counts as a diaper story to be honest.

This story is a sequel to Maternal Bonds of Eternal Friendship

Spike feels he is no longer relevant to Twilight, or any pony, ever since Twilight became the Princess of Friendship. With Applejack, Rarity, Fluttershy, Rainbow Dash, Pinkie Pie, and other ponies now receiving all the attention as he gets left behind to tend to chores, he questions his purpose and whether he really is seen as anything special by any pony.

When the Royal Wedding scatters defeated changelings all over Equestria, a member of the hive winds up being captured in Ponyville, tied up, stunned, repeatedly shot by a cannon, and held against his will.

The truly frightening part is he’s starting to like it.

This story is listed as comedy⁽*⁾ because the author has an odd sense of humor. No changelings were harmed⁽¹⁾ during the production of this story, despite what the newspapers printed or the ongoing lawsuit from the ESPCA⁽²⁾. The management would like to remind all readers to spay and neuter your pets. Unless your pet is a changeling, in which case…

(*) Dark humor, to be exact. If you are someone who finds pleasure in the misfortune of others, enjoys watching the occasional inept chainsaw juggler or cheers during a NASCAR crash, welcome home. Also, get help.

(1) Excluding blunt trauma, thermal impingement, chemical exposure, radiation, thaumaturgic infusions, and confetti ingestion. All characters represented, including changelings, are the exclusive property of Hasbro, no matter what they may shout at you from between the bars of their cell. Any violence or pain inflicted on the changeling in this story was simulated on a stunt changeling with special effects and mirrors. Except for the cannon. There is no truth to the rumor that Queen Chrysalis provided the stunt changelings from a supply of disobedient changelings in her dungeon⁽³⁾.

(3) The Changeling Kingdom does not have dungeons. They have Call Centers. It explains a lot, actually.
