Twilight and Sweetie sat on one side the carriage snuggling with one another while Derpy and Dinky were on the other snuggled close. The royal carriage was brought to Twilight that afternoon with a Royal Guard escort. Dinky and Sweetie squealed with filly delight when their pimped out ride, and the two older mares blushed at their excitement. Even the usually stoic guards d’awwed at the combined weaponized cuteness of those two as the bounced about the carriage, checking out all the sights of their sweet ride.

Now as they drew nearer to the castle they got as much affection as they could get before they had to hide their relationships from the two oldest rulers in Equestria. The near omniscient dream walker Luna, and her peeping tom, prankster of a sister Celestia. This could only end well.

It was several hours later, and thirty cleaning spells later that they arrived at the castle. Their anticipation of that special evening, and left them soaking wet several times, and Twilight was convinced that the smell at any given moment would be smellable to everypony in a twenty trot radius. But with her OCD level of thoroughness, she kept the sex smell suppressed.

As their carriage stopped they made a quick switch of positions seconds before the door opened revealing the smiling form of the royal sisters, “Hello Twilight, I see you brought your special somepony, what looks like her child, and your protege’,” Celestia said with a smile.

As she glanced at Derpy both her and Luna’s eyebrows cocked. Before a mischievous smile split their faces as who they were seeing clicked, “Madame Derpy, it’s been ages hasn’t it?”

Derpy blushed as everypony in the carriage looked at her in curiosity, “Not that long your highnesses.”

Luna gave a stallionly chuckle at that, “Oh-hohoho! That is quite the jest, it feels like forever since we last met.”

“Not really, it was shortly after you returned, and then on Nightmare Night,” Dinky said her blush brightening. As it hit her that arriving was probably a mistake. Even if it was for a good cause.

“The time sure does fly doesn’t it, and Luna don’t tease Twilight’s paramor just yet, at least not until she’s part of the family isn’t that right Twilight,” Celestia butted in before giving Twilight a playful bump on the shoulder with her wing.

Twilight covered her face with her wings and groaned, “I wish I could die, please if there are any merciful deities, please take me now.”

“Sorry Twilight I didn’t mean to embarrass you too much. It’s just that I’m happy that you’ve found love at long last, and it really has felt like ages since I saw Derpy last,” She looked at Derpy sadly, “We used to be close you know.”

“I know Celestia, it’s just been that I’ve been happily busy being a mother. You know how that is,” Derpy said sadly.

“Yeah,” Celestia whispered before cheering herself up, “But still there’s no need to be a stranger. We can catch up while you tell us all about your recent adventures.”

“Yes, I also wish to hear about your exploits since we last met,” Luna said giddily.

As they walked off ahead of them Twilight and the rest of the herd gathered around Derpy, “What was that all about?” Twilight asked.

“Well I promise to tell you shortly, just not right now,” Derpy mumbled embarrassedly.

“When then?”

“Tonight, when we have our privacy I’ll tell you all about it. All of you about it.”

“Alright, it’s just, weird that of all the stories Celestia told me about her past and of history, she never mentioned you. And I never saw you in the castle when I was a filly.”

“Please Twilight, I know you’re curious, and I do love that inquisitive mind of yours. But lets not go into this right now. For me?” Derpy added giving her biggest set of puppy dog eyes, with a cute little pout.

Sighing she said, “Okay it can wait,” lifting up a hoof regally she pointed it at Derpy, “But I better learn tonight, or you won’t get any.”

Derpy laughed at that and nuzzled Twilight, “I promise, tonight.”

As they sat at the massive, ornate, mahogany table, filled with delectable foods. Dinky and Sweetie Belle sat on either side of their respective mates while Twilight and Derpy sat next to one another. Each party hoping that it wouldn’t be conspicuous that their love sat next to them.

Celestia sat next to Luna who was seated closer to the group. Looking to make sure everypony was seated gave an announcement, “For those of you who are new to this dining room I will give out the rules now. One, no formalities, all of those things are left at the door. This is a place to relax and forget the outside world while around friends. Two, there are no rules, just enjoy yourselves and do what you want. Everything here is replaceable, but good times are not.”

With that she sat down, as Luna who had been chugging a large mug of Apple Cider from Appleoosa let out a loud belch, “Exactly, in this we’re only Luna and Celestia. So enjoy yourselves our honored guests and are to have lots of fun this night,” she ended her speech with a knowing wink that brought blushes from the fillies and nervous coughs from the adults.

“Anyways, Celestia, this here is Sweetie Belle the pony I’ve been telling you about,” Twilight said flush with nervous embarrassment.

“Sorry Twilight, it’s just been we thought the crusader’s would’ve ended up adults before you finally got around to finding a special somepony. And as an Alicorn you’re family, and even before then, you’ve been like a daughter to me. It’s my right to embarrass your dates to see if they have the guff needed to be part of the family,” Celestia said with a graceful smile.

“That’s right,” Luna said, “That and we’re hopelessly deviant when it comes to having fun with family.”

Celestia coughed and blushed, “Sorry Luna is still learning modern language. Isn’t that right sister?”

Luna blushed and nodded, “We’re sorry, it seems we have a bit more to learn about modern tongue after all,” She said a halo appearing above her head. Although the light seemed to flicker as if the bulb lighting it was faulty.

Twilight looked from one sister to the other before shaking her head viciously to shake out the images out of her head. While Derpy gave the first honest laugh of the night at the pairs antics.

After Derpy finished laughing she said, “Yes modern language can be tricky can’t it Luna?”

Luna grasping the save nodded her head. Derpy looked at Celestia’s blushing face and giggled, “It’s alright, I am honored that you’re teasing me to see if me and Twilight are good for each other.”

Luna blurted, “All she needs now is a marem, and we can give her a present for her first princessly milestone.”

Celestia poked her sister and gave her a knowing glance, “I told you Luna marem’s are rare now in days, all types of herd relationships are, after monogamy became a thing.”

“Yes, yes, true. Sorry Derpy, I shouldn’t have insinuated that you, Twilight and a group of other mares in your lives get together and have wild, happy sex. And carry each other babies. That was dated of me wasn’t it Twilight?” Luna asked.

Twilight at this moment was trying to sink beneath the table and disappear. Since her mind refused to release how to do the invisibility spell from the labyrinthian depths of her memory. She only let out a meep of affirmation before trying to sink lower.

“Anyways even if she did form one, we wouldn’t judge you Twilight, no matter what you do, or who you do it with. We’re family, and we care for you. Now Back onto business. Derpy how did you two meet?” Celestia asked.

Thankful for the shift of topic. She mentioned how her and Twilight first met when her and Raindrops dropped a piano on her head. Then the numerous times she ‘ran’ into Twilight on accident, finally ending with a few months before Heart and Hooves Day dating each other. Ending with how happy she was that Twilight knew that family came first and let her spend her Heart and Hooves Day with her daughter who had saved up for the occasion.

Celestia and Luna looked admiringly at Dinky when they heard the slightly truthful version of how much Dinky saved up and for how long she did so to help her mother. Luna had a tear in her eye, “That is the most beautiful thing I’ve ever heard. You truly must be a most magnificent daughter.”

Dinky blushed at the praise and shrugged which got a laugh from Celestia, “And she’s modest too. You truly do well raising your daughters. Even young Amethyst Star is a model student in the Academy.”

“Thank you Celestia. I try,” Derpy said with a proud grin.

“You know, with Twilight having a student, I think that Luna could use a student. It might help her acclimate to the world better, and help her connect with ponies like you have Twilight,” Celestia asked Twilight and Derpy.

“You know that might not be a bad idea. My little muffin has lots of magical power, I think it’s about 100 ++ SSMP Ponyville doesn’t have the room or machines to test for higher than SSMP, but I know that she’s at least half of what Twilight was at her age,” Derpy said.

“And that power only grows when a pony’s trained properly,” Luna said knowingly.

Sweetie Belle looked the sisters in confusion, “It can? My sister said that a ponies magical pool doesn’t grow much after they’ve hit their first estrus.”

“Well that’s both true and not. You see working magic is just like working a muscle. If you don’t push yourself, safely might I add, then it doesn’t grow. But the more it’s used, the more it needs, and the more bigger a ponies magical reserve and strength grow,” Celestia lectured.

“Hmmm … so you’re saying I can be as powerful as Twilight when I get older?” Sweetie Belle asked.

“You never know until you try, but Twilight’s reserves were always insanely high. But just remember, practice makes perfect, and hard work always pays off in the end,” Celestia said with a playful grin.

As dinner wound down. Celestia rang her glass, “To the ponies special to Twilight I give a toast. And also I have a surprise on top of the surprises in store tomorrow.”

“What surprise?” Twilight asked.

“This one,” and with a flourish of her magic, Celestia opened the doors to reveal Cadance. With an easily overlookable shake Celestia signaled that what the sisters already knew and Cadance could tell from a mile away Twilight didn’t admit to.

“Well honored guests we bid you ado. Sleep well, and if you need anything let our staff know,” Celestia said with a bow and together Celestia and Luna sauntered off.

Cadance looked at each of the ponies before her, and her eyes lit up with glee as she pranced in place squealing like a school filly, “Twilight I’m so happy for you.”

Twilight looked flabbergasted, “You know?”

“Twilight, you’re talking about three ponies here. One has access to a dimension that sees every event in a ponies life and has prophetic dreams. One has near omniscience by access to memories of every dreaming pony. And then you have me who can see all forms, flavors, and types of love. Did you really think it you could keep it a secret?”

“Oh no! Celestia and Luna must be so disappointed in me,” Twilight moaned.

“Silly filly, I know for a fact that they love, you. As well as are happy for you, very happy,” Cadance said with a smile.

Dinky nervously asked, “What about their feelings for me and Bright Eyes, they aren’t going to take her away are they?”

“No, never. Sure they came to me when they found out. Since a lot of times those relationships are formed by manipulation, need to dominate or control a pony, or are ponies would hurt another. But I can feel hearts and souls from the Crystal Heart, and I knew that your love was a pure one.

“So no, you have nothing to fear. Although if I know Luna as I’ve been learning of her, she wasn’t subtle about it at all was she?” Cadance asked playfully. Having leaned down and stroked Dinky’s back compassionately.

Dinky laughed at that, “Not at all. I knew they knew, I just didn’t know until you told me that I was right.”

“Well me letting the cat out of the bag can be our secret. And when you feel like you can tell them, do so. Personally, I never had a lover as young as you two, and I don’t think I’d love my foal when I have them that way. But I support true love, and I support my family which, Twilight, you should know by now you are. And if you love them, then I care for them as well.”

Twilight felt a huge weight lift off her back and glomped her sister-in-law, “Thank you Cadance, you have no idea how much that means to me. I don’t know when a good time will be to tell them, but can you let them know that I’ll try for tomorrow?”

“Sure thing, oh! And even though I never had a lover that young, I’ve heard Luna say that her and her sister would take on lovers that age before.”

“Really!?”

“They said something about when you hit their age, the age of a body is less important than the mind and soul that inhabit it,” Cadance replied with a grin.

“That’s great! But how come the laws say that it’s wrong if they’ve done it?”

“Well that’s the rub. They’ve always been private about their affairs. So it’s not been common knowledge, but they seemed to be glad for you, and see in you something special that can fix things for ponies like you, or even like them.”

“Really, Celestia prophesied that you’d be the one to give birth to thousands of torches that filled the skies with a hidden love, made known. And two ponies whose marks were born of that loves destiny would give birth to the Great Plan.”

“Great Plan?”

“I’m sorry Twilight that’s all I can tell you. Otherwise it could change prophecy. Well good night, and congratulations,” and with that Cadance left the ponies to their thoughts as they too left and made their way to the room they’d be in until sunday evening.

Author's Note

Man I loved writing Tia and Luna in this chapter. By the way, where love is concerned, never trust Cadance not to blab to the ponies involved that she knows about their dalliances. She's horrible at those secrets.

Also we're going to learn more about Derpy next chapter. Who can guess the secret?
