Chrysalis, still in the form of the Crystal Princess, awoke from her deep sleep and stretching out her hooves found herself alone on the bed. She lay there and looked out of the large window whose curtains were opened, letting in Celestia’s sun. Luckily there were no crystal pegasi (or unicorns for that) and so no pony would accidently fly up and ruin the royal couples, or their impromptu guest's, privacy.

Seeing that the sun was a fair distance above the horizon, it was no surprise to the changeling to find her hosts were already up. Chrysalis however was surprised to find she had slept so well, as she thought she would be missing her lavender furred sleeping companion. She surmised that as the threesome had finished much earlier than her and Twilights nighttime adventures, her body was using the opportunity to catch up on actual sleep, something she hadn't had that much of over the past few weeks.

As she stretched out on the bed popping her joints she heard the voice of a very familiar stallion call out “Good morning Chrysalis slash Cadence” Shining Armour smiled as he trotted back into the bedroom from the en-suite, having prepared himself for his days work.

“Oh, I should change shouldn’t I?” the Queen smiled and starting readying the spell.

“No stay like me, it’s fun to have a twin! I never had a sister growing up,” a soft voice rung out from a nearby room “and besides they say imitation is the best form of flattery!”

“And you don’t get enough flattery darling?” the princess's husband responded.

Cadence stuck her head round the door of her boudoir, her mane only half brushed “Not nearly as much as I deserve, I think you would agree?”

Chrysalis smiled at that one and decided it would be fun to double team the stallion “I seem to remember he used to be much more flattering before the wedding!”

“Yes he wasn’t, wasn’t he? I guess now he’s gotten what he wants, he thinks he can just get away with the odd comment now and then?”

Shining had already put his hooves on his hips in preparation for the mocking “Perhaps because there’s two of you floating around in my head, and Equestria, I have to spread out my compliments a little more?”

“Touché, dearest husband, Touché” Cadence replied “But Chrysalis, it might be best if you stay in my form during your stay.”

Hearing this made the changeling's face fall a little in disappointment, so Cadence went over and put her hoof on the lookalikes shoulder “Of course we don't want to make it seem like we don’t like to see you, but it’s sort of fun having two of me around”

“Well it was fun last night, so perhaps I should be you up here at least?” Chrysalis replied a little more cheerfully.

Shining opened the door and brought in three trays of breakfast that had been left outside “Actually, I do agree with Cadence...for once. I’m sure that the crystal ponies would embrace you if we were to order them, and in a few years I don’t think there would be a problem. But given their recent history, I think you’ll scare them being so much bigger then them”

Chrysalis looked a little confused, so Cadence filled in “You see, you do look pretty dark and scary like that evil King Sombra, even if you’re just a big softie now” she said, squeezing her duplicate in a hug causing her to laugh. “I don’t see a problem with your swarm, they are the same size but they still don’t trust many winged or horned creatures properly, just me their crystal princess. Shining sort of is a package deal!” she winked at her guest whilst her husband just groansed.

“Well, it could be fun seeing how they act around me if they don’t know which one of us is real. I mean, the ponies of Ponyville were friendly, but seemed much more relaxed around my swarm then me. Never thought that size would be an issue, but it kinda makes sense”

The two princesses on the bed walked over to where Shining had laid out breakfast at a small table, and the three sat down on some gathered cushions. Cadence took a dainty bite of some toast “You can stay here with us every night – there’s lots of space and we know the bed is big enough!” she spoke a little sultry “And you can feed off us as well, so it’ll be perfect?”

Chrysalis was sipping some tea, not needing to eat normal pony food. “What about personal space? Both mine and yours?”

“Well darling, you can use my boudoir if you need to, it’s my little place away from Shining Armour and his stupid stallion stuff!” Cadence poked her tongue out at her husband as he was tucking into a big bowl of basic porridge, a Royal Guard staple. Slurping noisily, he replied “Yeah, but you can go into my stallion-cave…”

“The proper prench name is ‘cabinet’ dear” Cadence corrected him

“As I said, my stallion-cave is off limits to mares and fillies!” Shinings eyes narrowed in response.

“What about if turn into a stallion?” Chrysalis asked with a smirk.

“Hmmm, can you play colt-of-duty?”

“Not as good as Luna, but I’m decent enough on many ponystation games”

“Okay, you’re allowed in, but stay as Cadence. She’s useless at computer games and it’ll be nice to pretend she wasn’t!”

“It’s not like that’s the most important thing in life!” Cadence replied a little defensively.

“I know you’re timeless or something, but are you aware of what stallions like nowadays?”

“I thought you liked me the most?” Cadence fluttered her eyes suggestively.

“Oh course I do, but the PS3 is a close second. When the fourth generation comes out…well, that order may change”

Cadence flung a sugar lump at Shining who caught it in his aura, and placed it in his mug of tea “Two lumps please” he laughed back.

Chrysalis watched “You guys are so cute, I feel bad for intruding into your lives like this”

“Are you mad? Last night was amazing” Cadence eyes misted over “And even if we hadn’t done that, I don’t think we would want you to be alone. Afterall, you have spent so long with only your subjects for company, I think you need a little friendship!”

“It has been lonely…” Chrysalis mused “I suppose you and your aunts would know all about that”

“Yeah, I worry about how Twilight will cope with her new status” Shining replied

“She’s got me…” Chrysalis started before realizing that she was about to give away their secret relationship. “I mean, she has all of us. She was the first pony to give me a chance, so I’ll always be there for her. And I’m sure Celestia will always be a mentor to her, and Luna owes her for the whole Nightmare Moon thing.”

“And she’ll always have me – I loved foal sitting her, and being shinys sister seals the deal!”

“Yeah, Twilly will be fine, she have all of you guys for after her friends, and me…are gone”

A contemplative mood fell over the two immortals, but Shining seemed unphased by the thought “Anyway, I’ve got a busy day training the crystal army today. Can you believe the Empire has never had a military?”

“They don’t really need it with the Crystal Heart and us about,” Cadence replied "I don't know why you're bothering?"

“I think it’s a useful thing to have on the off chance anything else happens,” Shining replied with a thoughtful gulp of porridge “I mean, changelings are able to go through the harmony shield so what if they had attacked…No offense Chrysalis”

“None taken, we would have attacked this place rather than Canterlot if we knew a place that actually runs on love...had it been around” Chrysalis laughed.

“So Chrysalis, we’ll spend the day together and we’ll all meet up before dinner – sound good to you Shining?”

The stallion got up and wiping his mouth on a napkin gave his wife a kiss on the cheek “Sounds good Sweetie, see you both later then” and he turned and planted a similar kiss of Chrysalis’s cheek, before trotting out of the suite.

“Wow, I never thought Shining Armour would give me a kiss goodbye, knowing it was me at least!” Chrysalis replied, moving a hoof up to her cheek.

“Well, don’t get too used to Missy!” Cadence replied, pausing to drink some tea “Remember he choose me in the end, so his all mine!”

“We’ll see about that!” Chrysalis teased back, the two ponies smiling at their newfound friendship.

After a busy day running a whole Crystal Empire, the two Princesses and the Prince met up in their chambers, a little tired but satisfied after a successful completion their royal duties, whatever they may have been. However, rather than talking about their day, Shining announced that they should go out for dinner where they could talk “But first, my dear wife, our usual rules apply”

Cadence eyes let up, and she let out a little squee sound “Goodie!”

“Chrysalis, you have to continue to take Cadence’s form for the rest of the night, and act as her the whole time. This means you are also bound by the same rules” Shining added, causing Cadence to clap her hooves excitedly.

“What are these rules?” the Queen asked in response.

“Oh no, you don’t find out until after you agree,” Shining replied with a smirk “But trust me, after last night I think you’ll enjoy it!”

Chrysalis thought about what that could mean, but given what she had done to Twilight that one morning she suspected that there may be some sort of public element to the pairs play – afterall, if the Queen had thought of it she could imagine this pair could have easily done the same. The thought turned her on so she quickly agreed “Okay, I’m in!”

“Well Chrysalis, you will be told the rules on a need to know basis. First rule is that there is no magic allowed to be used from this stage onwards unless it is an emergency”

“Oh, I can help there. If you spread my poison over my horn, it will take away my magic and keep me in whatever form I’ve taken. And of course it’ll work on Cadence as well. I already bottled some in case you felt like it” Chrysalis levitated a small vessel from a bag over to the unicorn.

“It’s not that simple - ” Shining put the bottle slyly to one side for future use “- you know how Cadence says she tries to minimise magic when she around the crystal ponies. Well, on these occasions she’s not allowed to use magic the whole evening. Everything has to be done the traditional way.”

“So, why not use my poison then?”

“Well, it’s still not safe out here, so far away from central Equestria” Cadence replied “and we couldn’t risk anything even semi-permanent in case a real emergency did occur. But we do have a certain something…”

As she was speaking Shining brought over two rings that looked almost identical to Cadence’s wedding ring “We have had these suppression rings made, two in case we lost one … luckily enough for tonight. They suppress alicorn magic but can be removed by the wearer so it’s safe, as long as the wearers hooves are free to remove it. I have no idea why I mention that part?” the stallion ended with a massive smile towards his wife.

The two Princesses looked each other, the real Cadence’s cheeks blushing fiercely. “So, Cadence is a submissive in the bedroom?” the Queen asked.

“Yes, actually last night was one of the most confident and dominate I’ve ever seen her!” Shining replied giving a hug to his wife “That made me so proud!”

Cadence hugged back “Well I can be dominant, but given as a princess we are so assertive in ruling the country, I like the idea of not being in control for a while”

Chrysalis thought back to Twilight Sparkle, and how she was now so submissive to her. She wondered if that was part of having so much power, or now with this latest news if it was an inherent Alicorn trait. The Queen thought she would have to try to find out from the one pony who would really know, Celestia, but bringing that up in conversation would prove a little interesting to say the least.

Shining passed the two Princesses the rings, and they placed them over their horns. Instantly the pair felt their magic dim, and they both shivered in excitement. "Oh, this is a fun twist - ” Shining called out “- with your magic’s suppressed, I can’t tell you two apart now” He closed his eyes “Both move about and either switch places or don’t, but don’t tell me” He could hear the shuffling and once it stopped, he re-opened his eyes “Now, I have no idea which one is which, so I’ll have to be as naughty and nice to you both, won’t I?”

Shining approached one of the Cadences and gave her a passionate kiss, before doing the same to the other. He then circled round behind his wives and checked each of their marehoods, which were both already equally damp in anticipation for some form of play. The stallion returned to the front and sniffed his hoof “Looks like you’re both lusting for me” causing both of the princesses to blush. “Right, If one of you gives the game away of whos who, there will be two punishments – one of my choosing, and one from the other!” and with that he trotted off to a large cupboard to the right.

The two Cadences looked at each other, and their minds reeled at the evil things they imaged the other could cause them, mostly because they would think of doing them if they had half the chance. Their thoughts were interrupted by Shining ordering them to move to the centre of the bedroom. The two princesses moved, and Shining approached with all sorts of equipment in his aura.

First he applied a tight corset to each mare which specially designed for Cadence with holes for her beautiful wings to go through. Shining waited for each alicorn to breath in and tightened the corset on each breath in to minimise the size, ending up with the corset tightened all the way closed, resulting in both Princesses having to take very shallow breaths.

The real cadence was used to this and despite her body being so slim to start with, it still felt restrictive. Chrysalis hadn’t felt something like this before, and whilst the body she was in was used to it, the changeling was not used to the sensations. It was nice, different, but weird. If she wasn't one of the immortals herself, she no doubt thought that she would have fainted right away from just how little she could breath This is going to make everything more difficult tonight the queen thought to herself.

With that task down, the stallion circled behind the pair again and levitated two identically shaped crystal cylinders in front of the mares faces. He couldn’t see their reactions, but suspected that their eyes bulged a little as the recognised the shape as Shining’s stallionhood. “Now, the question is do I lubricate these first or not…and don’t answer or they will be going somewhere much tighter then they were designed for!”

Both mares luckily for them stayed quiet, and so Shining balanced on his rare legs and gently ran a hoof across his two wife’s marehoods. Both princesses were unsurprisingly equally aroused, but Shining thought he would be nice...for a while. He settled back down and used his Aura to spread a lot of lubricant over the crystals and could practically hear the sighs of relief from the pair as they saw this happen in front of them.

He then brought the crystals back and placed one on the floor. He picked the other up by hoof, preferring to do this bit himself way rather than by magic. He wrapped his spare hoof round one of the cadence's tail, and pulled it to the side, exposing the royal lips. He teased the entrance with the crystal, before slowly pushing the phallus in until it was firmly seated. Releasing the tail with the other hoof, it instinctively rushed between the legs for modesty, making Shining laugh in response.

Unbeknownst to Shining he had picked his wife, and Chrysalis saw Cadence face blush as her tail was pulled out of the way. Even for the married mare, being forcibly exposed was a huge embarrassment and turn on, something the Changeling herself found it when Shining repeated the actions on her.

With the two mares suitably filled, Shining then levitated over some more equipment, a pair of items that made one of the Cadence’s groan in anticipation. “Luckily I couldn’t tell which of you that was – “Shining half growled, half laughed “- as otherwise that would have spoiled the fun. Chrysalis, I guess you don’t know what they are. Well, these are chastity belts but the prime purpose tonight is not to keep anything out…but to keep those crystals in”

Shining started wrapping the belts around the waists of the mares, before threading the crotch part between the mares hind legs. He pulled the belt tight forcing the crystal in right to it’s base, before a faint click of magic lock sealed the restraint in place. “Oh, and the reason Cadence hates it so much is that they are tuned to ignore the magic of the wearer. And with no other unicorns around, that means I’m the only pony for hundreds of miles that can release them! So theres no way of getting the belts off without you giving me some form of encouragement.

The last step was to help each of the mares into the dress and once this was complete the three of them looked into the rooms giant mirror. The pair of alicorn’s looked identical and equally stunning. With the beautiful dress on, there was no way of seeing the restrictive clothing on underneath, and with the tight corset and elegantly styled dress Cadence had never looked so slim and sexy.

“Wow, you never cease to take my breath away darling”

“Thank you” they both replied in unison.

“Although of curse that corset is really the thing taking the breath away around here” the stallion smiled as he went off to get his outfit for the evening.

Once he was out of earshot, Chrysalis turned to Cadence “So we’re really going out like this?”

“Yes, about once a week this happens in one way or another” Cadence blushed “I hope you like being as submissive as this?”

“Well I certainly didn’t put up much a fight last night!” Chrysalis replied

“That may be true, but this is different. You see the mixture of a…phallus -” Cadence blushed a bit at the word “- and the belt really brings home the helplessness.” Seeing chrysalis eyebrow raised, she continued “It’s the way the body just accepts it. Every so often you instinctively try to push it out but it doesn’t budge. And then your marehood just… endures the intruder.”

As if by the power of suggestion alone, Chrysalis found her body trying to move the crystal stallionhood but the belt held it firm and unmoving in her marehood. Her body then just automatically relaxed around the intruder. Cadence seemed to notice the Queens attempt, failure and subsequent reaction, and laughed a little “Its different with magic teasing, if you've’ve ever been involved in that. That overpowers you and becomes a battle of the minds. This, it’s just…so much more…primitive. Your marehood being physically forced to accept something…”

“…like it’s not even yours anymore” Chrysalis finished off, causing the pair to look at themselves in the mirror again. For anypony else it looked like Cadence was a beautiful and powerful ruler, but for the pair they knew they were the helpless princess waiting for her knight to release her.

At that moment, Shining reappeared in a modest version of his military outfit, something a little more casual and more in line with traditional formal wear. He went over and opened the bedroom door “After you, ladies” and the trio departed for dinner.
