Having trapped the Captain of the Royal Guard in the caves beneath Canterlot, Queen Chrysalis reappeared topside in the city with a flash of magic. She strutted up the road to Princess Cadance's villa. She was enjoying the long stride she had in her disguised form as Shining Armor. She knocked on the door. Princess Cadance opened the door a moment later, looking a bit distraught.

"Has the threat against Canterlot been resolved?" Cadance asked.

"Hmm? Oh, uh yeah," Chrysalis said in Shining's voice. "Um, the guys tried to take me to a bachelor party, but I didn't want to go. So I left."

"You were gone for quite a while," Cadance said.

"Well yeah. They flew me there but they didn't want to fly me back. And I don't have wings, so, I had to walk. So... that's why."

"I suppose that makes sense," Cadance said as they walked inside.

"So, how about some of that premarital sex that we often have?" Shining asked. Before she trapped him in the caves, Chrysalis had taken Shining Armor's seed to fertilize her eggs. Now she was anxious to use her male form to deposit them inside a mare's womb. She would make Cadance her hive's brood mare, hopefully sooner rather than later.

"Maybe tomorrow," Cadance said. "We should get some sleep. We have to get up early and get started on the wedding preparations." Cadance walked upstairs to her bedroom and climbed back into her bed. Shining joined her, laying behind her as the big spoon. Cadance felt Shining's erection sprouting behind her. He prodded under Cadance's tail with it. Beneath the veneer of his penis, Chrysalis's ovipositor sought out the mare's vagina. "You are incorrigible," Cadance said, pushing them apart. He tried again. "Shining! No!" Cadance said with an edge of anger to her voice. "If that's how you're going to be tonight, you can go sleep in the other bed!"

Chrysalis felt a pang of anger at the denial. Part of her wanted to just pin down the mare and force herself on her. The need to lay her eggs was a real one. But there was too much at stake to blow her cover now. She got out of the bed and headed down the hall to the other bed. In the past, she had carried her eggs for many days before finding a suitable partner. It was uncomfortable, but not unbearable. More importantly, she needed Cadance to love her. She needed to feed on her alicorn love magic to grow strong enough in time for the wedding. Two days would be worth the wait. Then she could take her time to enthrall the mare. She wouldn't say 'no' anymore after that.

"So I sent out the rest of the invitations," Princess Celestia said the following day. She was sitting at her desk, across from Cadance and Chrysalis, still disguised as Shining Armor. "So Shining, once you go to Ponyville to inform your sister, I'll send her invitation with the instructional letter for her friends," she said. "Shining?" Celestia asked.

'Shining' was barely paying attention. His eyes drifted across the desk to the letter-opener, day-dreaming about lunging across the table and stabbing Celestia in the throat with it.

"Shining?" Cadance asked.

"Hmm?"

"Are you going to go to Ponyville to personally tell Twilight about the wedding?" Cadance asked.

"What? No. Just send her an invitation like the others," he said, annoyed at the suggestion.

"Really Shining? It seemed pretty important to you yesterday," Cadance said.

"W- well... I don't want to be anywhere but by your side until the wedding," he said, truthfully. "Besides, she's a grown mare isn't she? She can read, can't she?"

"That pony does love to read," Cadance agreed.

"Fine. Whatever," Celestia sighed, sending off the invitation with a flash of her magic. It turned into a swirl of green smoke and went out the window to be received by Spike. "It's just as well. It will be more time for them to be here and help prepare for the wedding," she said, and then she did the same with the letter for Twilight and her friends.

In Ponyville, Twilight Sparkle and her friends were enjoying a lovely picnic. Spike had stepped away from the gathering and into the nearby woods to go 'water the bushes'. On his way back the spell reached him and he belched out the wedding invitation that Celestia had sent. His eyes scanned over the card.

"Princess Celestia cordially invites you to the wedding of Princess Mi Amore Cadenza and- OH SHIT!" Spike yelped and started to sprint back to the picnic to tell Twilight about her brother. By the time he got there, he was panting and wheezing. Being a librarian's assistant was not the best for keeping him in shape. Or getting him there in the first place. "Twi...Light..." he said between gasps. "I... have... lemme just-" He paused to catch his breath. Before he could, he lurched and belched another parchment. Twilight picked up the letter and read it aloud to her friends.

Dear Twilight,

I'm sure you are as excited as I am about the upcoming wedding in Canterlot. I will be presiding over the ceremony, but would very much like you and your friends to help with the preparations for this wonderful occasion. Fluttershy, I would like you and your songbird choir to provide the music. Pinkie Pie, I can think of no one more qualified than you to host the reception. Applejack, you will be in charge of the catering for the reception. Rarity, you will be responsible for designing the dresses for the bride and her bridesmaids. Rainbow Dash, I would very much appreciate it if you could just sit perfectly still and try not to break anything perform a Sonic Rainboom as the bride and groom complete their vows. And as for you, Twilight, you will be playing the most important role of all, making sure that everything goes as planned. See you all very soon.

Yours,

Princess Celestia

"But, I don't understand. Who's getting married?" Twilight asked, scanning over the letter again.

"Oh, wait!" Spike said, grabbing the other scroll to give to her. "Uh, I was probably supposed to give you this one first." Twilight took the scroll.

"Princess Celestia cordially invites you to the wedding of Princess Mi Amore Cadenza and- MY BROTHER!?" Twilight gasped.

Something in her mind snapped. Everything stopped. She felt herself become flooded with every possible emotion and reaction.

Firstly, and most predictably, was denial. She looked at the name on the invitation again in complete disbelief. There had to be some kind of mistake. Shining Armor. It was not a typo. It was her brother. Perhaps it was a prank. An elaborate April Foals joke. But it was far too late in the spring for that. And for as much as Celestia enjoyed the odd prank once in a while, this was too much, even for her.

"Your brother's getting married? Congratulations Twilight! That's great news!" Applejack said.

"Yeah, great news... that I just got from a wedding invitation, not from my brother, but from a piece of paper! I mean really, he couldn't tell me personally!?"

Denial gave way to anger. Anger was an uncomplicated emotion. Anger gave her issues a laser focus. He promised that he was going to talk to me about us! she thought to herself. And now I get this out of the blue!? He knows that I love him. I LOVE him!

"Um, Twilight, are you okay?" Fluttershy asked.

"Sorry, it's just that Shining Armor and I have always been so close. Before I came here and learned the importance of friendship, he was one of the only ponies I ever really accepted as a friend."

I just need to talk to him, she bargained with herself. I just need to reason with him and get him to change his mind about this. About me. And then we can be together again. Or if not, to at least still share him.

"Your brother sounds like a real good guy," Applejack said.

"He is pretty special," Twilight said, feeling depression set in. "I mean, they don't let just anypony be Captain of the Royal Guard."

"So let me get this straight. We're helping out with the wedding of not only a princess, but a Captain of the Royal Guard!?" Rarity asked.

"I guess we are," Twilight said with a shrug of acceptance.

The group packed up the picnic and then they each packed for their trip to Canterlot on the next train.

"Alight. Up next you need to go down to the train station to greet the arrival of your sister and her friends," Cadance said to Shining.

"And then we put them to work," Shining said. "And then that will free us up to head back home and-"

"Save it for the honeymoon, dear," Cadance said. "We have a lot to do. All of us. Twilight and her friends are just here to help out. Not to do all the work for us. I'll finish up here and be with you at the station shortly."

"Fine." He agreed to be separate from his source of food and power briefly, if only to play along in the role. Once Chrysalis dealt with placating this 'Twilight' pony, she could get back to getting Cadance alone long enough to lay her eggs in her.

He watched the train pulled into the station and waited for the ponies to disembark. His eyes scanned the crowd, looking for the unicorn that matched the one the photos in Shining's bedroom. He spotted the purple unicorn among her entourage of friends.

"Shining!" Twilight called out, running over to him. Her expression was equal parts excited and upset. She closed the distance and hugged him quickly. "We need to talk," she said in a curt whisper.

"Yes indeed. I trust that you received the instructions from Celestia for helping with the wedding?"

"I need to talk to you in private," Twilight said. He stifled his annoyance and looked at the others.

"Fine. The rest of you all have a job to do. Let's get to it!" he commanded. The others excitedly scurried off to their castle accommodations to unpack and then get to work. "Now let's make this quick. I need to get back to my bride."

"You promised me that we were going to talk about things!" Twilight said. "And then I get this invitation to a wedding out of the blue! How did you think I was going to feel?"

"Invited?"

"Shining! What about-" Twilight looked at the ponies around them, careful not to talk about such a scandalous issue in public. "What about us?" she whispered.

"Well I'm getting married, and you can be my Best Mare if that helps." Twilight scowled and led him away from the busy streets up onto an empty promenade.

"I don't care about being your Best Mare. I want to be your-"

"Twilight?" Cadance asked. "Twilight, how are you!?" she practically squealed.

"Cadance?" Twilight's eyes lit up upon seeing her old foalsitter. She put her anger on pause as she ran over to greet her.

"Sunshine sunshine, ladybugs awake! Clap your hooves and do a little shake!" the two mare said together as they did their little dance.

"What are you doing here?" Twilight asked.

"I'm getting married!" she said. "Didn't you get the invitation?"

"Princess Mi Amore Cadenza!?" Twilight asked. Cadance rolled her eyes.

"It's a muzzle-full, I know. But yes, that's my full name. I guess I just never told you when I was foalsitting for you. I always just preferred 'Cadance' anyway," she said. "I'm so glad you and your friends are here to help with the wedding. Speaking of-"

"They went to go unpack in their rooms," Twilight said.

"And then they're going to get to work," Shining said.

"And so are we," Cadance said, leading Shining towards the castle kitchen. Twilight decided that she would need to have a word with Shining later when she could get him alone again. When they got to the kitchen, Applejack had already begun working with the other cooks on the wedding banquet. Twilight took out her wedding preparation checklist.

"Cake, check," Applejack said, putting the finishing touches on the cake. "Ice sculpture, check... Best darn bite-size apple fritters you ever tasted..." Applejack fed one to Twilight.

"Check," Twilight said, pleased with the food at least. Cadance walked into the kitchen after Twilight, with Shining in tow.

"Hiya Princess!" Applejack greeted.

"Please, just call me Cadance," Cadance said.

"Hiya Cadance! You come to check out what's on the menu for your big day?" Applejack asked.

"I have!" Cadance answered. Applejack offered her a fritter. Cadance held it in her magic and took a bite.

"Delicious!" Cadance said. "I love, love, love them!"

"Aww shucks. Why don't you take a few to go?" Applejack said, giving her several in a bag. "I know how you brides can be. So busy you forget to get a little something in your belly. And what about you, Shining?"

"That's Captain Armor to you," he said.

"Sorry sir," Applejack apologized. "Something to eat?"

"No." He glanced at Cadance. "I've been snacking all day."

"Well don't fill up too much. There's going to be a feast for you tomorrow," Applejack said.

"Oh, I'm looking forward to it," he said with a grin. He followed Cadance to their next stop, and Twilight followed closely after. They headed to where Rarity had set up her seamstress workshop.

"Your Highness," Rarity greeted. "Let me just start by saying what an honor it is to play a role in such a momentous occasion."

"Is my dress ready?" Cadance asked.

"Oh, uh, yes, of course!" Rarity said, leading her to the dress on the mannequin. "I've been working on it ever since I was given the assignment, and I think you'll be pleased with the results." Rarity helped Cadance into the wedding dress for a final fitting. It needed no adjustments. It fit her perfectly. She looked in the mirror and was speechless. Her smile told Rarity all she needed to hear. It was perfect. Rarity helped her back out of the dress and turned her attention to Shining Armor "And you?" she asked.

"Oh, he's going to wear his uncle's vintage guard uniform," Cadance said.

"That's... right sweetie," Shining said, forcing a smile and nodding in agreement.

"Oh. Well alright then. That saves me from having to tailor a tuxedo for you," Rarity said. The next stop was the reception hall where Pinkie Pie had, predictably, decked out the place with the perfect decorations for a six-year-old's birthday party. It was complete with a pinata, music, and games like Pin the Tail on the Pony.

"Okay, let me see," Pinkie Pie said, bouncing about the room with her usual, unnatural amount of energy. "We've been over the games, the dances! I think this reception is going to be perfect! Don't you?"

"Yes, perfect!" Cadance said as she danced along with Pinkie Pie. Shining remained unmoved as he watched them dancing like foals, commenting only that he was 'saving his moves' for the big day. At the final stop in the castle fauna garden, even though Shining commented that one of Fluttershy's choir birds was singing off-key, Cadance agreed with Fluttershy that the rest of them were enough to balance out the harmony.

Rainbow Dash required no visit. Either she would be able to so a Sonic Rainboom, or not. Cadance was no expert on advanced flying, and found it strange that Shining had no opinion in the matter, despite Dash's performance being his enthusiastic suggestion the previous day. In either case, Rainbow was rarely available for a visit, dividing her time equally between flying really fast in the sky, and napping. With the sole exception of that evening when it was time to grab drinks with her friends. The six mares and Spike all sat at a big patio table outside of a city cafe.

"No cider for you, Dashie?" Applejack asked of her borderline-alcoholic friend.

"Heh, remember the last time I did a Sonic Rainboom?" Rainbow asked. "How loud it was?"

"Yeah?"

"Well imagine that, but with a hangover," Dash said. "Plus, it's nauseating enough trying to pull seven Gs without rotgut. I can wait until after the wedding."

"I guess," Applejack said.

"Speaking of, it certainly was generous of Princess Cadance to have an open bar for the reception," Rarity said.

"And you would know a thing or two about generosity," Pinkie Pie said with an unsubtle wink. "By the way, open bar, my idea. You're welcome Dash."

"Well there's no way that can go wrong," Rarity sarcassed. "A wedding party with an open bar, a pinata, and Dash armed with a melee weapon."

"Ooh, that actually sounds like it could be quite dangerous," Fluttershy said.

"Yes dear, that was the joke," Rarity said.

Twilight just sat quietly in her seat at the table. Her presence there was not by choice, but out of obligation to her friends. Despite her best efforts that day, she could not get any time alone with her brother to speak to him about their issues. But what had been more troubling to her still, was the apparent change in him, personally.

But the more she thought about it, the more alienated she felt, surrounded by friends, but feeling alone all the same. She couldn't talk to them about the way she felt. How could she? None of them knew Shining Armor. He was a stranger to them all. The only pony that would even be able to relate to her concerns was-

"Why the long face, sugarcube?" Applejack asked Twilight.

"I'm just thinking about Shining Armor," Twilight said. "Something's wrong, but I can't tell what it is. I don't know how or when he changed, but he changed all right."

"What d'ya mean?"

"It's like... it's like he doesn't even know who I am. He has barely even acknowledged that I even existed today. We were always so close growing up. But ever since I moved to Ponyville, we've been seeing each other less and less. And now that he's starting a new family with Cadance, we'll probably never see each other!"

"Come on now. You're his sister. He'll always make time for you."

"He couldn't seem to make time to tell me he was getting married! And now he just spends all of his time with her. I can't even get a hoof-full of minutes to just talk to him!"

"Maybe you're being just a tiny bit possessive of your brother? There's no call to be taking it out on him." Applejack said. The others nodded and hummed in agreement.

"I am not being possessive! And I am not taking it out on him! None of you know what he was like before. Something is wrong and I'm going to get to the bottom of it!" Twilight said, slamming the table with her hoof before storming off.

Something was wrong, Twilight thought to herself. And in all probability, it was her. Her every thought was plagued with nagging doubt. Every time that Shining had rebuffed her advances in the past. Each memory was weighed down with guilt accumulating on her shoulders. There was only one other pony she could talk to about him. And it was the very mare angling to wedge herself between her and her brother forever. But what choice did she have? She walked up the road to Cadance's villa. Twilight knocked on the door. Cadance opened it a minute later.

"Yes? Twilight!" Cadance greeted with a hug. Twilight quickly looked into the house behind Cadance for her brother. He was strangely absent.

"Is Shining here?" Twilight asked.

"Yes. He's upstairs trying on his suit. What's up?" she asked. Twilight had rehearsed what she had planned to ask, and say, a dozen times on the walk over. But now that she was here, she was lost.

"I- can we talk for a minute?" she asked her old foalsitter.

"Of course. What's wrong?"

"It's about Shining. It just seems like... there's something off about him. You know?" Cadance just gave her a warm, reassuring smile.

"Oh, I'm sure he's just a little unlike himself because of all the excitement. You know how he gets when he's stressed out," she said.

"But that's just it," Twilight said. "I do know what he's like when he's stressed out. And this isn't that. This isn't from stress or the pressure. He's the Captain of the Royal Guard, he can handle both of those things. It just feels like he just so... different. It's like I don't even know him anymore. And he acts like he doesn't even know me."

"Twilight," Cadance said. "One of the important things that Aunt Tia has taught me, from her long life as an alicorn, is that the only thing that is constant... is change. Ponies change. Sometimes it's because of other ponies, or things that happen in their lives that change everything. Like getting married? But the changes are only on the outside. The important parts about him, that make him your brother, and the stallion I want to marry, deep down, stay the same. He might not be affected by stress, but his appetite might be. And if he doesn't eat, he may get irritable?"

"I guess..." Twilight grumbled, inwardly hoping that it was truly that simple, but she knew that things between her and her brother were anything but simple.

"Listen, it's getting late and we all have a busy day tomorrow," Cadance said. "I'll make sure that you get a chance to talk to him about how you're feeling after the rehearsal ceremony tomorrow, okay?"

"Okay. Yes, thank you, Cadance." Twilight said.

"You're important to him," Cadance said as she hugged her. "And you're important to me, too. Tomorrow is going to be the happiest day of my life. But I want you to be happy, too."

Twilight bit her lip, unable to imagine herself being happy witnessing her brother being officially taken from her for good. She tried to blink back her tears. This must have been what Shining had been trying to warn her about all this time. In what possible reality could Twilight have ever have dreamed to have a happy ending to her fairy tale with him? How could she have ever entertained the crazy idea of marrying him herself? Were they to both stay single forever? No, it was almost as impossible.

This outcome was inevitable, whether it was sooner or later. Twilight knew that, and she knew she had to accept it. She had to accept that Shining would want to marry somepony someday. Obviously it couldn't be her.

And taking a step back, objectively, she could not think of a better choice in her eyes than Cadance. Cadance clearly loved him. He made her happy. And she must make him happy as well. She could be happy for them, at least, couldn't she?

"Yes. I can do that," Twilight said before they finally parted. They bid each other good night and Twilight went back to her lodging to get some sleep.

The rehearsal the next morning went well. At least, in the execution of the ceremony's steps. Everypony was in the right places at the right times. Speakers got their lines right. Nopony lost the rings. A success by anypony's standards.

Twilight, however, was less than pleased with how the whole affair went. The entire time she could not take her eyes off her brother. He, on the other hoof had his entire attention focused on Cadance. Twilight could understand this, to a degree. It was their big day. But even so, Shining, barely even looked at her. Was he intentionally ignoring her? she wondered. Did it really hurt so much for him to look at her, knowing what had happened between them, and now both of them forced to go through all this, pretending like none of it ever happened? Maybe she wasn't the only one of them hurting. Shining never was very good about coping with emotional vulnerability.

True to her word, Cadance gave Twilight the opportunity to find out. Cadance walked with Twilight to the groom's dressing room. Shining Armor was close by Cadance's side, just as he had been all morning.

"Twilight, why don't you stay here in case Shining needs any help while I go get into my dress," Cadance said. Shining tried to object to being separated. Cadance chided him. "You can't see the bride in her dress before the wedding ceremony starts. It's bad luck. I'm sure you can wait for thirty minutes," she teased.

"Yes... dear," Shining begrudgingly agreed. Cadance gave him a parting kiss and closed the door. Twilight waited until the sound of her hoofsteps were gone. She turned and looked at her brother.

"Shining, we need to talk," Twilight said.

"Well make it quick," he said with annoyance. "I have a wedding to get to in half an hour. Perhaps you've heard about it?"

"Yeah. I heard about it. From a wedding invitation!"

"I was of the impression you were capable of reading," he said.

"The point is I heard about your wedding from an invitation! Not from you in person!" she said. He recalled the discussion of the importance of him going to Ponyville. This must have been that.

"Is that what this is about?" he asked.

"You know what this is about!" Twilight said, feeling the tears forming in the corners of her eyes. "I LOVE YOU!"

Beneath the veneer of the stallion, those three words, along with Twilight's emotional outpouring, hit Chrysalis with the shock of a bucket of ice water. That was when she felt it. She had felt it ever since Twilight had arrived to Canterlot. Suddenly so many things made sense.

For the changeling, Cadance's love was like a song playing on the radio. But ever since Twilight had arrived, there was an interference to the music, like static, distorting the sound of it. And now that Chrysalis was far enough away from the saturating radiation of Cadance's alicorn love, she could hear it, taste it, and feel it, clearly from Twilight Sparkle.

Tainted Love.

The tainted love of Twilight's forbidden desire for her brother was a rare treat for the changeling queen. It was far stronger than the normal bond of bland familial love. It was sweet, yet spicy, but also bitter. Like dark chocolate infused with red pepper. And like the food, it was not very nutritious, but it was a sweet delicacy. Shining's mouth practically watered.

"After all the times that we..." Twilight trailed off, searching for the words. "... that we were intimate, I never thought that out last time would be... our last time. I've thought about you every day since then. You promised that we would talk about it. About us! When you told me that you loved me too, was that a lie!?" She was nearly in tears. Chrysalis was struck with a most wonderful, awful, terrible idea. Shining smiled.

"Whoever said that it had to be our last time?" he asked. Twilight's breath hitched in her throat, scarcely able to believe what she had just heard. Did he really mean that he wanted to...? As though reading her expression, he nodded. She ran over to him and threw her hooves around him. She hugged him and kissed him. He kissed her back. His tongue matched hers with the same frantic passion of her desperate lust. She trembled in his hooves, practically melting from his touch at last. All of the fear and doubt about his behavior before evaporated in an instant. She had never been so happy to be wrong before.

Shining broke the embrace and walked over to the bed and patted the mattress with his hoof. They didn't have time for the full affair. They had places to go and things to do. Twilight didn't mind in the least as she quickly hopped onto the bed and rolled onto her back. Shining pulled her hips to the edge of the bed. He reared up, proudly displaying his massive erection. Now it was Twilight's turn to have her mouth water. But it wasn't the only thing that was plenty wet.

Shining took his shaft in his hoof and guided it down to the wet entrance of her marehood. Twilight practically bucked her hips against him, eager to have him inside. He was only too happy to oblige, working the rest of it into her. Twilight stifled her moan as she felt him fill her at last, scratching that itch that she didn't even know she had. They were both older, grown ponies. But even so he felt even larger than she remembered, almost disproportionately so. She felt him bottom out inside her.

Beneath Shining's white fur, Chrysalis was feeling euphoric. Twilight's love wasn't as powerful as the Alicorn of Love. But while the consummate love from Cadance was a slow, steady feed of nutrition, the energy from Twilight's tainted love was like a concentrated rush of crack cocaine. Chrysalis's magic reserves thrummed with the temporary over-charge.

Chrysalis focused her concentration on Shining's penis, letting it take the form of her ovipositor. The head changed from being rounded and blunt to a narrow tip. His precum became a powerful cocktail of muscle-relaxing analgesic, and aphrodisiac. It started by numbing and relaxing the muscles of Twilight's cervix. As he continued to thrust, the tip extended into the small opening. Once inside, it swelled thicker, prying her open in preparation for the delivery of Chrysalis's fertilized eggs. Twilight felt no pain, only the tingling from the changeling's potent secretion. For the mare, it was like the pleasurable sensation of a small, but continuous orgasm. Chrysalis felt her eggs shifting inside her, ready to be implanted into the mare.

"I'm gonna come," Shining said, bracing her for the strange sensation of him pumping into her.

"Yes!" Twilight gasped. Her head was swimming from the effects of the changelings nectar.

"I'm gonna cum inside you Twilight! I'm gonna get you pregnant!"

"Yes!" Twilight all but begged for it. Her addled mind would have made her agree to anything in that state.

Chrysalis felt the pressure building inside herself, signaling her imminent delivery.

KNOCK KNOCK

"Places ponies! The ceremony is about to begin!" a voice said from the hallway.

Panic shocked Twilight back to her senses and scurried away from Shining for fear of being caught in such a position.

"Just let me finish!" Shining said, trying to hold onto her.

"There's no time for me to clean up after!" Twilight yelped, pulling off of him. She twisted and rolled onto her belly to climb off the bed. Left in the lurch on the brink of cumming, Chrysalis quickly turned the ovipositor back into his penis before Twilight could see it, and retracted it at will. Twilight cleaned herself as best as she quickly could and neatened her mane in the mirror. "Come on, let's go!" Twilight made for the door but stopped at the last second. She looked at him. "I know you're getting married but... Is this going to be our last time?" she asked. Shining smiled.

"I promise you, it won't be," he said. Twilight smiled. They walked out to the ceremonial hall to take their places.

Cadance was running late with getting into her dress. But alas, with a wedding, the bride is never late. Everypony else is merely early. They all waited patiently in position. Shining and Twilight exchanged occasional glances. He smiled at her. She smiled back, more than she had the entire time since they had arrived. Until she stopped smiling. After a few minutes her face twisted into a grimace and she clutched her stomach. She keeled over.

"Twilight are you okay?" Applejack asked. Twilight shook her head.

"My stomach hurts," she groaned. Shining looked on in genuine concern. Chrysalis knew what this meant. The numbing effect of the changeling serum was wearing off and Twilight was feeling the pain of her cervix having been stretched and penetrated. Normally, a brood mare would receive a numbing aftercare effect from the eggs in their womb. But Twilight never received the eggs. The pain must have been excruciating.

"I'll take her to her room," Shining said. "I'll be right back." Nopony objected to the stallion caring for his sister. He lifted Twilight onto his back and carried her to her room. Once inside, he closed the door behind them. She staggered to her hooves, working through the pain as she shuffle off her dress, noting the bright green stain. She reached back and felt under her tail, finding more of it on her hoof.

"What- what is this? Some kind of infection?" Twilight asked.

"This is an opportunity to finish what we started!" Shining growled as he grabbed her and pinned her against the dresser. He mounted her and she felt him prodding at her entrance again.

"Shining! No! Not like this! It hurts!" she cried, looking at her brother in the vanity mirror.

"It'll feel better soon," he said into her ear. Twilight felt a sharp sting and saw stars as his tip hit her tender cervix again. But a couple more thrusts and his fresh changeling secretions melted her pain away, left only with the mind-dulling pleasure. The tip of Chrysalis's ovipositor penetrated Twilight's numb cervix again, stretching it open completely, letting the rest of the shaft inside. The head blossomed open like a horrible flower, ready to release her eggs deep inside Twilight's womb.

Chrysalis's eggs began to move into her ovipositor. She started fucking her against the dresser harder, causing it to bang against the wall. The entire floor of the castle was vacant. Everypony was down in the wedding hall. The vanity mirror slammed against the wall and cracked in half, a portion landed on the bureau in front of her. Twilight looked into the broken piece on the dresser. She could see the refection of the rest of the mirror in it, the reflection of Shining's reflection.

But it wasn't Shining.

Twilight's eyes blinked wide in abject horror as she beheld Queen Chrysalis's true form in the reflection's reflection. The horrible, terrible insect monster that was now pinning her down and raping her. Her equine instincts reacted faster than her as a unicorn. Her hind legs reared up and she bucked her with every ounce of strength she had.

She was no apple-bucking earth pony like Applejack. But the element of surprise caught Chrysalis completely off guard and the full force of the double kick sent the changeling reeling across the room, tumbling backwards across the bed and onto the floor beyond. Viewing her directly, most of her was still wearing Shining's appearance. But Twilight witnessed the monstrosity that was the queen's ovipositor just as she began to cum. Eggs began to uncontrollably pump from the tip, landing fruitlessly on the dry, inhospitable floor. Chrysalis's shrill voice cried out for the premature end of her unhatched grubs.

Twilight was still in shock at the sight. The thing with Shining's face got back to his hooves. The dissonance in Twilight's mind stayed her magical attack just a moment too long. Chrysalis slammed Twilight with her green magic, creating a portal in the floor with a ring of fire, sending her the crystal caves to be dealt with later. She could not have one of her drones killing Twilight by accident. She was going to take her time with that mare, and make her pay for what she had done to her forsaken clutch of eggs. She would breed her with eggs a hundred times over until she died from it. But Chrysalis had no time to mourn the loss of her clutch now. It would be of little importance soon. She refreshed her Shining Armor disguise on her ovipositor and put it away once more. With Twilight disposed of, nothing would stop her from finally having it all.
