This story is a sequel to The Mane Six Regret Playing Truth or Dare

Months ago, the Mane Six played their first round of Truth or Dare. As a result, they ended up having a rap battle, learned about secret crushes, and managed to start a beautiful relationship between one of the Mane Six and a Wonderbolt. Since their first game, Starlight Glimmer and Spike joined the fun. This week is the same as always. But little do they know, two unexpected guests come to play.
The rules are simple.

2. If choosing Dare, you must perform the dare some pony dares you to do.
3. You cannot change your choice once you have selected something to perform.
4. You cannot choose somepony to dare you to perform something or ask you something.
5. The game ends at midnight when Princess Celestia and Princess Luna say it ends.

It's recommended to read What Happens at the Lit Club... and The Mane Six Regret Playing Truth or Dare if you want to understand some stuff that's going on.

This story is a sequel to A Most Irregular Tea Party

Now that Twilight is in complete and utter love with Princess Celestia, there's nothing better to do than bring her new marefriend to Ponyville to show off to all her friends. There's no way this can go horribly wrong!

FEATURED!

"June, honey, be a dear--reschedule Luna and K.K. That's what I call Princess Celestia--what a hoot!"

K.K....K.K...K.K...

Ever since hearing this little tidbit from Spike, Princess Celestia has been wondering just why in the world Discord would call her K.K.? She could understand a pun about the sun or an insult using her actual name or even a mocking version of her royal title, but K.K.? What does the nickname mean?

Finally, Celestia decides to just ask Discord. Discord, however, realizing how curious she is, offers to tell her only in exchange for a little favor. After strong negotiations, Celestia agrees to his terms and finally founds out what K.K. means...and the answer makes her realize many things about her relationship with the chaos master and the magic of friendship.

Letters. Everyone writes them, and they're not just for ponies. Be they carriers of serious news, friendly correspondence between pen pals, or declarations of heart and heartbreak, each one is written with a clear purpose or goal in mind.

Celestia uses them to try and keep her faithful student and friends in line, and try to keep an unbalanced world on the straight and narrow.

This is much harder than it sounds.

Now with an audio reading by Lady Tenkage!

Old-Fashioned Bar Hoppers, featuring Celestia, Mayor Mare, and Granny Smith shenanigans.
Journal of an Adolescent Clone, featuring Sunny and Moony shenanigans since Season 5.

Since her return and rescue, Princess Luna has been looking for some way to properly honor the six mares who saved her from herself, but nothing she has been able to think of has seemed meaningful enough to repay her saviors.

Nothing, at least, until she spends Nightmare Night in Ponyville, and gets to actually know the six ponies to whom she owes such a great debt. She realizes she enjoys their company, and wishes for them to spend more time with her, that she might grow closer to them.

So, in accordance with many fine and ancient traditions, and after thinking it over for a good...couple of hours, easy, she proclaims that she shall marry all six of them. Oh, and that Twilight will be marrying Celestia, too.

Now would be the appropriate time for everypony to panic.

NB - The sex tag is in place for sexual situations and suggestions; the story is, and shall remain, free of explicit sex.

On what seemed to be a typical morning, Pinkie realizes that she had accidentally slept in and quickly runs to school as fast as she could but when she arrives, she finds out that she was in such a hurry that she forgot put on her underwear.

Now she must try as hard as she can to keep a lid on it and make sure no one realizes that she's going on.

Includes humiliation, some butt exposure, mooning and of course Pinkie going commando. If you don't like it, don't read.
