Polyamory

They chose Twilight, again, to ensure the wedding went well. She was determined to do just that. Since Celestia was in the wedding, Twilight would perform the ceremony as well, but Twilight hoped to get them to exclude a particular participant.

Fortunately, they had given her more time than before to prepare. The actual wedding itself wasn’t until tomorrow.

No one in the marriage thought Chrysalis was up to anything, but Twilight knew better. Chrysalis always was, and this time her friends, and plenty of other ponies, agreed with Twilight. At least a little, though her friends asked her not to crash the rehearsal this time, especially since she would be running it.

Twilight told them she’d consider it.

She figured that she’d start by asking Cadance for her side. They’d added Chrysalis so abruptly that Twilight hadn’t been able to speak to Cadance about it. Shining said it was Cadance’s idea to add Chrysalis, and Twilight trusted him, but it seemed out of character, even for a mare as affectionate as Cadance.

Twilight knocked on the door. She had learned to never enter a room with Cadance inside without knocking, whether Cadance was with her husband, a casual friend, a complete stranger, or even by herself.

“There’s my favorite sister-in-law!” Cadance smiled as she opened the door. Neither her nor Shining was dressed up, though the same dress and suit from their own wedding was hanging nearby.

Of course Twilight was Cadance’s only sister-in-law, until after the wedding at least. Afterward, Luna and Celestia would be both Cadance’s wives and her sisters-in-law… Maybe Twilight should avoid thinking of it that way though. This whole union was a nightmare for terminology.

“Hey Twilly,” Shining waved from further inside the room. He smiled, though there was a hint of dread on his face.

“Everything going well I take it?” Twilight forced a smile. “I uh, wanted to talk to you before the wedding, if you didn’t mind?” Twilight peered as she considered. “You are Cadance and Shining Armor, right?”

“It’s me, Twilight,” Cadance assured. “Chrysalis promised to only be herself during the ceremony, as have her guests… children… descendants…whatever. Either way, I’m sure you’ll find her surprisingly adorable once you see her decked out in whatever Rarity comes up with.”

“Is it true?” Twilight asked. “Shining said… that it was your idea… about Chrysalis.”

“It was,” Cadance said. “Twilight, please believe me. Chrysalis was every bit as surprised as you when we asked her to join us. This isn’t some scheme of hers.” She smirked. “This is my scheme.”

“It’s a scheme everypony involved is okay with,” added Shining. He came over and hugged Twilight, kissing her on the forehead. “All the same, I’ll let Cadance explain. She’ll do it better.”

“Cadance,” Twilight looked up at her, whispering as if self-conscious about her words. “I trust you, you know I do… and I respect your decision but… Cadance… she raped him, didn’t she?”

“Twilight,” Cadance patted the side of her face with a hoof. “Had she come as herself and asked to play, we would have consented.”

“That isn’t the point,” Twilight sighed. “She didn’t know that, and she did it anyway.”

“Twilight, it isn’t the same with her as it is with a pony,” Cadance explained. “Chrysalis has trouble controlling herself because of her biology, but she’s trying to do better. It’s hard to undo years of instinct.”

Twilight breathed deep and looked away. She trusted Cadance, but knew she might stretch the truth to spare Twilight’s feelings.

“I’m not implying what she did was okay,” said Cadance, gently turning Twilight’s face back to her. “But if you were starving, would you feel guilty for taking food from somepony who had more than her share?”

“No,” Twilight whispered.

“That’s all it was,” Cadance reasoned. “Chrysalis was hungry and afraid for her children. She made some big mistakes, but her intentions were the same as yours or mine would have been in her situation.”

“I guess,” Twilight didn’t want to admit that it made sense.

“Twilight, I promise we will take you seriously if you see anything suspicious,” Cadance said. “But promise me you won’t hurt her feelings with unwarranted accusations. I know you think of her as a monster, but she’s a very emotional creature. She acts smug, but it’s just her way of coping. Inside she desires your acceptance.”

“I promise,” nodded Twilight.

Cadance leaned in and hugged Twilight close, sliding her telekinesis around and giving Twilight a nudge under her tail to lighten the mood. Twilight squeaked and blushed, but wasn’t surprised. It wasn’t the first time, and not the last, that her affectionate sister-in-law groped her or her friends.

“I’ll get some things ready now,” smiled Cadance, then winked. “No crashing the rehearsal this time, especially with you running it.”

“I did what I needed to do.” Twilight realized Cadance meant no offense, but it bothered her that Chrysalis probably told Cadance about it like it was hilarious. And that everypony was making that joke.

“I know you did the right thing, Twilight,” Cadance petted Twilight’s mane and then kissed her forehead when her attempt at levity failed.

“I’ll resist crashing anything, for now,” Twilight forced a smile, not wanting to seem too bitter around two of her favorite ponies.

“Go visit her,” Cadance suggested, though visiting her was inevitable if Twilight were to check on everything. “Tell her nicely what worries you. I’m sure you can work something out, okay? She might be with Rarity; she was having challenges with Chrysalis’ dress.” Making Chrysalis look good in a dress would be a challenge.

“We want you to be comfortable, Twilly,” Shining added, briefly hugging her. “We’re here whenever you need us, but let’s work towards being one big happy, if unusual, family.”

“I’ll try,” Twilight promised. “Where’s Celestia and Luna?” She’d feel better if she talked to them first.

“They’re with Applejack, I think,” Cadance smiled, then gave her a brief hug. “I’ll see you at rehearsal, Twilight.”

Cadance closed the door, and Twilight sighed.

“Maybe we should have waited for her to join first?” Cadance asked Shining inside. Twilight didn’t understand what that meant, but Cadance sounded flirtatious, so it was probably none of Twilight’s business.

She headed to where Applejack was overseeing the baking for the event. This time she didn’t take the time to knock since it wasn’t like the royal sisters would be making out while eating cake or some-

Oh.

Applejack was holding a cake that she was letting the royal sisters try, wide-eyed and sitting stiffly. Luna had Celestia laid back half upon one table, belly to belly with her, grinding together as she fed Celestia cake a spoonful at a time. Celestia eyes rolled back further with each bite until her pupils weren’t visible. It wasn’t clear if Celestia was enjoying her sister’s company or the cake more.

Celestia had the decency to blush furiously, though Luna looked more shameless. Twilight could even hear the moist sound of their… parts… rubbing together. That was a more pleasant thought than she wished it was and tried very hard to keep her own parts from getting damp.

“Um, so ah take it ya’ll like tha cake?” Applejack asked, averting her eyes. “Ah sure am glad ya approve… yer Majesties, but maybe we should leave some fer the actual wedding.”

“One moment, fair Applejack,” Luna responded, then turned to Celestia. “Tonight, sister, you shall devour cake from all your favorite parts of me. Indeed, from all of us.”

“Is this a bad time?” Twilight’s voice cracked when she spoke, but felt better that her mentors were enjoying themselves.

“It is not, Twilight Sparkle,” informed Luna. “Did you also wish to consume cake?” Luna didn’t cease grinding. Cadance must have rubbed off on her.

Celestia reacted less casually to her faithful student’s presence. She shoved Luna off with such force that the night princess landed upon her back on the floor. Luna didn’t get up, instead smiling as she watched her sister try to regain some semblance of dignity in front of her student.

“Hello Twilight,” Celestia smiled her best fake politician-smile. “It’s so wonderful to see you, I was just… making sure the food was… delicious.”

“It’s fine, it’s just.” Twilight said with shifty eyes. She thought back to how many times she had scolded ponies for believing the rumors that the royal sisters were involved in an incestuous relationship. Twilight had made a foal of herself as was typical, but did think they made a sweet couple. “It’s fine, really. I’m happy for you. I’m just… distracted.”

Her eyes moved to the major source of distraction in the room, namely Celestia’s plump belly, plump with Chrysalis’ changeling spawn… or grubs… or whatever the little monsters were called. It was larger than Luna’s subtle curve despite having been implanted later. Twilight watched Celestia’s belly visibly writhe, and quickly looked back up at Celestia’s face. Celestia was still blushing and silent.

“Princess Celestia, I just wanted to ask if some things were true,” Twilight took a deep breath.

“Have you not read the paper, Twilight Sparkle?” Luna asked, still laying on her back with her legs splayed shamelessly. She floated a newspaper over to Twilight’s face, opening it. The paper sported a photo of two sweaty Celestias on the throne. Twilight wasn’t sure which was the real Celestia, as she couldn’t see who was penetrating who. Thank Celestias.

“You did it in public?” Twilight squeaked. She didn’t have enough energy for her surprise to have much force behind it, but public impregnation wasn’t typically something royalty did.

“Luna!” Celestia blurted out as she tossed the newspaper aside again, and turned to Twilight, speaking calmly. “I suppose I learned a friendship lesson in… the dangers of keeping oneself pent up.”

“I don’t care that you had sex in front of anyone,” Twilight said. “It’s WHO it was with. She… hurt you, almost killed you.”

“Chrysalis didn’t almost kill me,” smiled Celestia, trying to seem gentle but unable to lose the blush. “Changelings can’t feed off love toward somepony without a ‘live feed’ dear. A changeling killing a pony would be like a pony burning crops.”

“Really?” Twilight’s mind switched into science mode and for a few moments forgot to care. “But what happened to Shining’s offspring?”

“These are Shining’s offspring, Twilight,” said Celestia, patting her belly, which writhed again. “And Chrysalis, and mine. Changelings can produce children from three parents.”

“If you desire a lesson in changeling biology, the best source would be the literal mother of the species, Twilight,” Luna said, standing up and motioning to Celestia not to speak further.

That put Twilight’s brain back on target, and she grumbled. Of course, they’d want her to talk to Chrysalis about it, hoping that she’s start to like her. Twilight felt torn. It fascinated her, yet she had to talk to Chrysalis to learn more.

“Celestia,” Twilight sighed, “Just… swear to me that you’ll be careful? Please don’t trust her.”

“Has she performed an act that aroused your suspicion?” Luna asked, which Twilight appreciated.

“She hasn’t,” Twilight admitted.

“I can trust her, Twilight,” Celestia said. “It’s hard to explain why.”

“Try?” asked Twilight.

Celestia clearly didn’t want to answer, shifting a hoof about nervously. “She could have forced herself on me psionically, more easily than you’d think, but she chose not to. She chose to let me decide on my own.”

“I guess? If you’re sure.” Twilight wasn’t.

“Go talk to her,” Celestia smiled and gave her a hug. Celestia felt sticky with her and Luna’s sweat.

Twilight felt somewhat better, so she turned to check on everything else.

“Fair Applejack!” Luna exclaimed as Twilight was shutting the door. “Fetch your princesses a vat of toffee!”

Twilight avoided thinking about that further.

It wasn’t far to where Rarity had been making their outfits. Luckily, or not, Chrysalis was still there.

“I look like a curtain!” Chrysalis could be heard complaining from within.

“Nonsense!” Rarity replied, “You look absolutely adorable. I’ve covered all your most uncouth parts.”

“Are you calling me ugly?”

“No, I’m calling you frightening.”

“… thank you.”

That didn’t sound kinky, so Twilight opened the door.

Chrysalis was decent, and more adorable than Twilight would admit. The dress had a nice silky train that covered her somewhat grotesque, at least so far as Twilight was concerned, hindquarters. She had sleeves over her front legs too, separated from the main gown. Along with the vest portion, the only gross parts of the changeling that showed well were her creepy bug wings and that holey frill on her head she called a mane.

Chrysalis faced Twilight, looking like she would say something snide. Instead, she must have remembered what she was wearing, because she blushed instead.

Chrysalis and Rarity were the only decent individuals present. There were changelings everywhere, most being only minorly indecent by getting into Rarity’s fabrics or playing ‘dress up’ on each other with outfits not intended for them. A few though were engaged in more stereotypical changeling behavior, including a pair of drones who were violently mounting no less than a few steps from Rarity.

Rarity looked frazzled as if she’d spent all day trying to keep bugs out of her stuff and had finally given up. She politely pushed the humping drones further away with her magic as their bodies slapped together, not looking at them.

“Oh, hay Twilight!” the drone getting mounted said when he saw her, as if nothing was strange at all about screwing while his Mom was dressing several hooves away. “Is Pinkie around?” Oh, so it was THAT changeling.

“She’s busy planning,” Twilight tried to be polite. “Please don’t bother her while she’s working.”

“Oh okay, I’ll fuck her when she’s done,” the drone smiled, then rolled his eyes back and went back to enjoying who was probably his brother, given they were all Chrysalis’ children. “Think she’d mind if I brought a few siblings along? Not many, like a dozen or so.”

“She’d probably like that,” sighed Twilight. Pinkie loved to make everypony, and everybug, smile.

“Great!” smiled the drone as he shivered.

Rarity sighed too, “So uncouth.” She then tried to smile for Twilight. “Hello Twilight, I certainly hope things are going better for you than I.”

“They’re going… fair,” Twilight smiled to Rarity, then peered at Chrysalis.

“Goodness,” Chrysalis chuckled, “Does it look that bad?”

“No,” Twilight admitted. “Rarity covered all your most frightening parts, like she said.”

“The MOST frightening part isn’t normally visible,” Chrysalis winked. “You know, the part I’ll be ramming belly-deep into your brother’s posterior tonight. And your mentor. Ovipositor for everypony!”

“Chrysalis,” Twilight growled. “I have promised to be nice to you, but please don’t try my patience.” All the same: curiosity. “Oviposi… how exactly does that work? What you did to… Celestia.”

“Your hot brother impregnated me,” Chrysalis smiled. “And then I pumped the result into your mentor. The eggs will cannibalize her own natural eggs and extract the genetic material so that the offspring are genetically related to all three of us.”

“So, they’ll be like… two-thirds pony and one-third changeling?” Twilight tried to silence herself, but the question escaped.

“They’ll be 100% changeling,” Chrysalis grunted as if offended by the idea of a part-changeling. “The offspring of a changeling is always a pure changeling. How else do you think I made a brood when I was the first and only changeling?”

“Wait, you were the first?” Twilight blinked, “I assumed you came from a whole species. Who was the first… Wait, never mind.”

Chrysalis smirked, “Oh, I piqued the geeky one’s interest.” She leaned forward and smiled more. “Intelligence is sexy, you know.”

Twilight groaned, “I don’t suppose there’s a book I could read on this so I don’t have to talk to you about it?”

“There isn’t, unless you want to write one. I’d be happy to demonstrate changeling breeding habits for you… all night long.” Chrysalis winked. “Then you could write the book on it yourself.”

“Should I fuck her?” asked the mounted drone.

“We’ve been over this, Doomie,” chuckled Chrysalis. “Ask her, not me.”

“Oh right,” Doomie nodded, looking at Twilight. “You wanna fuck?”

“Um, no thanks,” Twilight could believe she was asked that; it was a changeling after all. But that didn’t make it less gross.

Damn it. Twilight had a hundred questions now. How did Chrysalis come to be? Twilight didn’t mind that the answers would be gruesome; she was capable of keeping scientific detachment. But the only creature with the information was the creature that she didn’t want to ask.

“Believe it or not, Twilight,” Chrysalis said in a surprisingly non-smug tone, “I want to be friends with my new husband’s family, so let me know if you can tone down your racism enough to have tea with me sometime.”

“I’m not racist!” Twilight said defensively. “And you’d probably poison my tea.”

“With aphrodisiac,” smirked Chrysalis. “It’ll be some bomb ass tea. And sure you aren’t.”

“Do be fair, Chrysalis, darling,” Rarity mentioned as she made final adjustments to the dress. “Ponynapping her loved ones and invading Canterlot wasn’t the best way to make a first impression for your species.”

“I didn’t say it was unjustified racism,” Chrysalis smirked and reached to pat Rarity, though Rarity dodged the pat, pretending to move to another seam to do so.

“Just don’t cause…” Twilight started, but realized it was silly to tell a bride to not cause trouble at her own wedding.

“Oh, I’ll cause trouble,” Chrysalis’ eyes narrowed. “These pony ceremonies are so boring on their own. Besides, I think Sun Butt would be disappointed if I didn’t at LEAST abduct somepony. You know how bored she gets at big events.”

“Don’t give me a reason to regret giving you a chance.” Twilight made that plain. “Or to make you regret making me regret it.”

“Oh-ho,” Chrysalis giggled, eating up the threat more than Twilight intended. “Relax, though. I won’t come near you or your family, other than my spouses, unless asked. Despite how hot your mother is. Now there’s a plot that could hold some eggs. Reckon your father would like to-“

Twilight clenched Chrysalis’ muzzle shut with her magic, then turned to walk off.

“See you later!” called Doomie after her, clueless about the strife. He had to raise his voice since the one atop him was squealing in orgasmic bliss.

His ignorance was admittedly adorable. One thing Twilight had to admit: Despite looking scary, most changelings were pretty innocent. The only reason they’d done anything wrong was because their mommy told them to. Not that it mattered; as long as they did what Chrysalis said, they were a threat.

“You promised you wouldn’t antagonize her,” Rarity complained to Chrysalis as Twilight was exiting.

“I also promised my children would behave in here,” Chrysalis answered simply.
“An adequate point,” Rarity admitted.
