Fireworks exploded in the skies above Canterlot, being specially made to be seen despite it being the middle of the day.

Within the royal castle, a large crowd of ponies were gathered inside one of the larger rooms. The same room that had held the Royal Wedding and the coronation of Princess Twilight. That crowd was a mix of famous dignitaries from other nations, along with ponies that would normally never be seen in such a place. The only reason they were, was because of their close friendships to the ponies that the crowd had gathered for.

Music filled the room, as the entrance of the hall suddenly opened and several individuals stepped inside.

Those individuals walked in single file, each one wearing a beautiful dress. The first was Applejack, with Big Mac walking beside her. Next was Rainbow Dash, who had Soarin Skies beside her. This was followed by Fluttershy, Rarity and Pinkie, each of them walking beside ponies that many people recognised as members of the royal guard.

As the crowds stared at these three mares, their attention was drawn to their bulging bellies. For each mare was visibly pregnant, roughly eight months if the crowd had to guess. And whilst the ponies wondered who the fathers were, they didn't give it much thought. After the recent births, the thought of unwed mothers had slightly changed.

Speaking of births, many in the crowd heard the sounds of young ponies. And they looked around to the front of the seats, where a trio of ponies was sitting with foals on their laps.

The first was Shining Armor, who had his mother beside him with Princess Flurry on her lap. And he was holding the first Alicorn Male ever seen. Prince Blitz Shine.

On his other side was Luna, who had a five month old baby in her arms. This alicorn was also male, sharing his mother's dark blue coat. However, his hooves wings had orange feathers in them. He also had blue hair and his mother's eyes, the child appearing annoyed that he was awake right now.

And next to Luna was Celestia, who was carrying a baby that appeared to only be two months old. This child was female, having his mother's white coat and hair that was a mix of pink and blue with blue eyes. The child seemed to be fast asleep, not disturbed at all by the music or the other loud noises as her mother held her tight.

These were Sunny Glow and Dusk Haze, the future rulers of Equestria. And they had been the centre of attention, ever since they had been born. But not today.

No, the centre of attention on this day, was the mare currently stepping into the room as the music started.

Princess Twilight Sparkle, dressed in a gorgeous wedding dress, walked in alongside her father. Heading towards the stallion she had come to truly love and admire. The one that had made all her dreams come true. Both the public and the secret dreams,.

Flash Sentry smiled, as he watched his bride approaching him. He then took a moment to look around the rest of the room. At the friends and family there, including his parents, cousins and several friends from the guard.

He took a glance over at the bridesmaids, who were all sitting since the pregnant mares would be uncomfortable on their feet if they stood for too long. He then glanced at the mare that would be marrying him to the love of his life. The Princess of Love herself.

The beautiful mare's body had really bounced back from her pregnancy. Once again, there was no sign that she had given birth. She was as beautiful as ever, Flash's mind briefly flashing back to the night he had had with her lookalike...if she was a lookalike.

Cadance smiled at him and he smiled back, then turned back to Twilight as she got closer and closer. And when she finally reached him, Flash and her father smiled at each other before he handed his daughter over to him.

The pair held each other's hands and smiled at each other, as Cadance began the ceremony.

Flash barely paid attention to what she said, too focused on the mare in front of him and the future they would have together. He didn't know what kind of path they would end up walking, but he was happy to walk it with her. And after giving their vows, Cadance said those all important words.

"You may now kiss the bride." Flash didn't need telling Twilight, as he took Twilight's check in his hand and leaned forward. As their lips connected, almost everyone in the hall cheered and clapped. Only those holding foals weren't, though the smiles they were giving the pair showed just how happy they were about this whole thing.

Everything after that was a total blur for Flash and his new wife, as pictures were taken and they all headed over to the garden that would host the party. There, the food was given out and the toasts were made. Flash's best man, Cluster, made everyone burst out laughing.

After that, it was time to cut the cake. And after he and Twilight cut the first piece, the Princess of Friendship used a spell to evenly cut the rest of it so that everyone could get a piece without waiting.

Once that was done, Flash and Twilight enjoyed their first dance. And they truly enjoyed this, Twilight hugging her new husband as others joined them on the dance floor. Spike danced with Dragon Lord Ember, the newlywed's parents danced, Rainbow pulled Soarin out to show everyone how to do it and even Shining took little Flurry out to dance.

This left Celestia, Luna and Cadance to sit on the side. Each of them was holding their child, smiling as they watched everyone having fun. "I'm so happy for them," Cadance stated. "I hoped they would get together. I just didn't expect them to get married so quickly."

"Yes," Luna nodded, "I wonder why Twilight was so insistent on being wed so soon." Dusk started getting fussy, the mare holding him in her arms as they kept watching the two dance.

"Maybe Twilight just knew it was meant to be," Celestia suggested. "Cadance and Shining were excited to be married as soon as possible." Sunny was snoozing in her mother's arms, Celestia holding her close to her heart.

"Yes. But we had been dating for years before then. I didn't even know Flash and Twilight were dating before they announced their engagement."

"I guess that's karma for you not telling her you two were dating." Luna smiled. "Either way, they're married now. And I'm sure Sentry will keep Twilight happy for a long time." The other two mares nodded, knowing that Twilight would be very happy with Flash. After all, they had all experienced just how happy Flash could make a mare. Even if they couldn't announce that to anyone.

The party went on throughout the evening. After Flash and Twilight finished dancing, Twilight went to dance with her father whilst Flash and his mother danced. After that, Flash happened to dance with Rarity, Pinkie and Fluttershy. Each mare could only dance for a little bit, needing to rest after a short while whilst Flash danced with another. A little while later, those three mares chose to retire for the night. And Flash got to dance with Twilight again.

Another hour or two past and the party began to wind down, with Flash and Twilight sharing a little more time with their friends and family before Twilight pulled her husband to her side and held him.

They then waved good night to everyone else before Twilight wrapped the pair of them in her magic and warped them both away. "Oh yeah," Soarin laughed. "We all know what they're gonna be up to." He turned to Rainbow, "bow chica bow wow."

"Please," Rainbow rolled her eyes, "you realise Twilight's probably gonna spend the night too embarrassed to do anything. She and Flash are probably gonna get to their room and as soon as Flash takes something off, Twilight will probably faint."

"You sure?" Soarin asked. "That sounds more like something Fluttershy would do and...well..." Rainbow frowned, still amazed that Fluttershy of all mares had wound up pregnant. Rainbow was still trying to figure out who had done the deed with her best friend. But hadn't uncovered the secret.

"Trust me. Nothing sexy is gonna be happening in Flash and Twilight's room tonight.

Thirty minutes later.

The sound of gagging could be heard in Flash and Twilight's room, as a naked Flash stood before three pregnant mares currently kneeling on the floor. Rarity, Fluttershy and Pinkie held their bellies, as they enjoyed their lover's cock.

All three of them were wearing the same thing. White stockings, garters and elbow high gloves. They all looked like they were wearing sexy wedding lingerie, which coupled with their large bellies made them one of the most erotic sights Flash had ever seen.

Rarity was currently deep-throating his cock, whilst Fluttershy and Pinkie were sucking and licking his balls. The three all moaned, continuing to rub their bellies and even play with their nipples as they began to leak.

"Oh, fuck." He smiled at them, as they smiled back and kept pleasuring him. "Fuck, I wish I could fuck all three of you right now."

Rarity pulled her lips off his cock, Fluttershy quickly replacing her as the unicorn looked up at him. "Now, dear. You know the doctor said we can't have sex until after the babies come." Flash nodded, excited for when he would get to meet his children. Even if he was married to Twilight, he had every intention of being part of these foals' lives. And if anyone figured out he was the dad, screw them.

"Besides," Pinkie popped her mouth of Flash's cock. "Tonight's not about us. We're just here to get you revved up." The others nodded, as the mare of the hour stepped into the room.

Twilight smiled at the sight of them, as she too was dressed in sexy wedding night sleepwear. Except she was also wearing a silk set of panties and bra. The alicorn leaned against the doorway, looking as sexy as she could whilst watching her sister-wives enjoying their husband.

"Okay, girls." They all turned to her. "I think it's time my husband and I consummated our marriage." They nodded, though they looked upset that they wouldn't get to play with him anymore. "Don't worry. I recently found a very special spell. Been saving it for tonight." Her horn lit up and she fired a spell at Flash, which swirled around him for several seconds.

"Err...babe?" Flash watched, as the light flew off of him and began to make something beside him. And in the blink of an eye, an exact replica of Flash was standing right beside him. "Twilight?"

"It's a magical clone," Twilight giggled. "It uses the same kind of magical powers as the mirror pool. Except this one only lasts until the magic I used runs out. No chance of him going rogue on us." Flash and Clone Flash stared at one another, both a little weirded out. Clone Flash gave off a slight glow, so there was no mistaking who was who. And as Flash moved over to the bed, Clone Flash turned his attention on the ladies.

Flash and Twilight smiled at one another, as Flash pulled her in and they started kissing. He grabbed her ass and lifted her up, Twilight wrapping her arms and legs around him as they moaned into each other's mouths.

Flash carried her over to the bed and once he placed her down, Twilight pulled away and leaned back to lay upon it. "I'm ready Flash. No more needing to be careful. I want you to fuck me and cum inside. I don't know if it'll make a baby, but I think it's time we found out how powerful your cum really is."

Flash smiled at her before leaning forward and kissing her on the neck, Twilight moaning as she let herself lay upon the bed and felt Flash begin to grope her chest. The feel of Flash's lips and teeth on her neck, was like nothing she had ever felt before.

Flash began to play with her tits, kneading and twisting them through her bra. "Oh yes. Right there. Don't stop." Flash kissed under her neck, beginning to move lower until his face was in front of her chest. As he did, he carefully pulled her bra down to let her tits bounce free.

This allowed Flash to stick his mouth on her breast, sucking upon one as he kept tweaking the other one. Twilight gasped and moaned, loving this feeling.

As this was going on, the other girls were having fun with Clone Flash. Pinkie was currently sucking on his cock, whilst C-Flash played with Fluttershy and Rarity's breasts. As he squeezed on Rarity's, his mouth was sucking upon Fluttershy's and she moaned.

"Oh, Flash. No. That's for the baby."

C-Flash laughed. "She won't need this for a good while yet. So until then, I can enjoy it all to myself." He sucked again, Fluttershy groaning as he sucked more and more of it out of her. And once he had his fill of her milk, he popped his mouth off and turned his attention to Rarity.

He licked at her nipple, making her moan as C-Flash played with Fluttershy's breast. He licked all around the bud before sticking his mouth on her breast, sucking upon it until the milk flew out. "Oh my," the unicorn sighed. "Darling. Don't suck too hard. You might stretch my breast. I've already gone up two bra sizes. I'd rather not have to replace the underwear I took so much time making."

C-Flash chuckled and sucked, moaning as he tasted the milk flowing out of Rarity's breast. All the while, Pinkie had gotten his entire cock into her mouth. She pushed her head down until her nose pressed against his groin, moaning around the length as her breath was completely cut off.

Back on the bed, Flash continued to suck upon Twilight's breast. And as he did, his other free hand had been pressed into Twilight's panty clad pussy. "Oh yes!" She cried, feeling Flash's fingers push her soaked panties into her cunt. The feeling was driving her crazy, whilst Flash's mouth and other hand made her tits feel amazing.

Flash pulled his head back and kept his suction on the breast, causing it to stretch as Twilight's back arched on the bed. And when he released the breast, it bounced back and almost hit Twilight in the face.

She laughed at this, as Flash's fingers did a figure eight on her cunt. "So good. Fuck! I've waited so long for this." Flash smiled and finally moved to grab her panties, slowly pulling them down Twilight's legs. She lifted her flank to help, then her legs so that Flash could completely remove them.

Once that was done, Flash moved down and placed his face upon her cunt. And as the mare moaned, he ate her out whilst reaching up to grope her tits again.

He did this for several minutes, Twilight's voice getting louder and louder as she was driven towards her climax. As this was happening, Clone Flash was doing something rather interesting with his girls.

Fluttershy and Rarity had placed their stomachs together, close enough to not hurt the child within them. And as they did, C-Flash pushed his cock between them and started thrusting into their bellies. The mares didn't know why, but this felt absolutely amazing.

Pinkie was now knelt behind C-Flash, her face pushed into his ass and licking at it.

Rarity and Fluttershy kept moaning, as Flash's arms were wrapped around them and squeezing their now empty tits from behind. All the while, C-Flash moaned at the feeling of their stomachs around his cock and Pinkie's tongue in his ass. He might have only been a magical copy, but he still felt incredible.

Everyone moaned at the pleasure they were feeling from one another, Twilight by Flash's tongue, Rarity and Fluttershy by C-Flash's cock and C-Flash by Pinkie's tongue. And eventually, Twilight and C-Flash couldn't take any more.

"I'M CUMMING!" They both cried, as Twilight squirted her juices all over Flash's face. He happily kept lapping at her cunt, whilst hearing his clone groan out.

Fluttershy and Rarity both moaned, as they felt something squirt against the parts of their belly that were touching. And as they slowly pulled away, bridges of white slime kept them connected with C-Flash pulling his cock away.

Pinkie moved out from behind Flash and crawled over to them, opening her mouth as the cum bridges broke apart. Her mouth suddenly stretched all the cum fell into it, Pinkie sucking it down and moaning in delight as the other mares giggled. Pinkie then licked at Fluttershy's stomach, making her gasp and moan in delight.

Twilight panted, having come down from her orgasm but still feeling Flash's eating her out. "Oh, Flash. No more foreplay. I'm ready." Flash heard this and pulled his face away from her pussy, smiling up at her before slowly moving up. As he did, he kissed her body. Going from her cunt, up her stomach, around her tits, then to her chest and neck.

As he began to suck on her neck again, making her moan some more, he pointed his rock hard cock at her cunt and rubbed it against the entrance. "You sure you're ready?"

"Yes!" Twilight gasped. "I can't wait any more. I want to feel your cum inside me. I want you to breed me, like you bred all the other mares." Flash smiled before thrusting his hips forward, making Twilight gasp as she felt him pry her cunt apart.

Flash grunted, loving the feel of Twilight's pussy around his cock. And as he leaned down to kiss her, Twilight wrapped her arms and legs around him to pull the stallion deeper into her pussy.

The pair began to fuck one another at full speed, Flash's cock diving all the way into the princess' cunt as she clutched him tightly. All the while, they moaned into one another's mouths whilst Flash's hands rubbed against Twilight's ass. And when they finally pulled apart, Twilight let out several cries of pleasure.

"OH YES! RIGHT THERE! DON'T STOP! FUCK ME! FUCK ME HARDER!" Flash laughed, as he started kissing her neck again. The two kept going at one another, moaning and gasping. Soon, Flash's cock was pressed into Twilight's pussy all the way and she screamed in joy.

At the same time, Clone Flash was busy pleasing the other three members of the harem. Currently, he was on his knees whilst the mares were bent over. Each one was holding onto a chair, using it to keep themselves table as they moaned at what C-Flash was doing.

The stallion was currently eating Pinkie out, his tongue swirling around her cunt and making her gasp and groan. At the same time, his fingers were pushing into Rarity and Fluttershy's pussies. Both mares were crying out as well. If some one had been looking at them from the front, they would have seen the pregnant unicorn, pegasus and earth pony looking like mindless bimbos.

Each of them had their mouth opens, cries escaping them as their tongues stuck out and their eyes rolled into the back of their heads. The three Milfs in the making were all being pushing towards orgasms, as C-Flash's tongue and fingers worked their magic within them.

"Oh yes!" Rarity cried, "right there, darling."

"Don't stop!" Fluttershy panted. "Please. I'm so close."

"Eat me!" Pinkie pleaded, "eat me and make me cum!" C-Flash heard this and was pushed on, the pegasus construct wishing he could fuck these mares. But he would have to settle for this.

Twilight's cries also drew their attention and when they all looked back, they found Flash was now on his back as Twilight bounced up and down on him. "Of fuck!" She cried, "fuck me harder!" Flash grunted, holding her hips and pulling her down onto his cock.

Twilight's tits bounced every time she slapped herself down onto him. She groaned and bit her lips, as Flash watched his wife's breasts swing around.

"Oh sweet Celestia. You're hitting my G spot. I'm gonna cum soon!"

"Me too!" Flash groaned, as he reached up and groped her tits. "And I promise, I'm gonna get you pregnant. And not just once. I'm gonna breed you as many times as you want. All of you."

The three mares heard this and all moaned. They were already excited about being mothers to one of Flash's foals. The thought of having more sounded like paradise to them. They weren't sure how quickly Flash intended to impregnate them again after they gave birth, but they were going to look forward to it.

Twilight panted, as she felt Flash bang against the entrance of her womb. And as she felt his squeeze her breasts, she bore down upon him harder and let out a cry as she felt her cervix begin to give way. "FUCK!" She cried, as Flash entered her womb. "Yes! FUCK! DON'T STOP! DON'T YOU DARE PULL OUT! SPERM ME!"

Flash groaned, thrusting his hips up into her cunt harder. But it wasn't him or Twilight who came first.

Fluttershy screamed, as her body shivered and she sprayed her juices all over C-Flash's fingers. Rarity then followed, with Pinkie close behind. They all moaned, their legs threatening to give out on them. But they held on, as C-Flash kept eating and fingering them to orgasm. And it wasn't long afterwards, that Twilight screamed.

"I'M CUMMING!" Her entire body began to shake and she lost control of herself, causing her to almost thrust herself up and off of Flash's cock. But he wasn't gonna leg that happen.

He thrust up into her before flipping them both around, Twilight's head landing on the pillow as Flash once again lay on top of her. And as he did, his cock got even deeper into her womb. "FUCK!" He cried, thrusting into her several more times. And eventually, he let out a roar and filled Twilight up with his life giving seed.

Then, something happened.

Suddenly, Flash's body started glowing. It was a strange white glow, at first, which was enough to catch everyone's attention.

As Twilight felt herself being filled up, the light made her look up and see her husband glowing white. "Flash?" The stallion had his eyes closed, so he didn't notice the glow. But the others did, each of them looking confused as Flash's aura changed colour.

Suddenly, it changed to a strange light blue colour. This was when Flash finally opened his eyes and looked down at Twilight, only to see her worried expression before noticing the glow. And as he did, the glow changed to a dark blue colour. "What is this?" He asked, as Twilight placed her hand on his chest.

She looked worried, as the aura then changed to a golden colour. "Flash. What's going on?"

"I don't know," he told her. Then, his aura changed to be a dark purple. "But...I feel...wow." He felt strength, in a good way. Like he had just slept for ten straight hours. His exhaustion was also gone, like he could run a mile a still have enough energy to fuck every mare in Equestria.

As that was happening, the aura around him began to change into a mix of the four colours. Blue, dark blue, gold and purple swirled around him before appearing to be absorbed by his body. And when they did, he felt something new within him. A fire. A power. He didn't know what it was, but it was amazing.

Twilight could also feel the power coming off him and also knew this wasn't a bad thing. She didn't know why she knew that, but her heart was telling her this was a good thing. Whatever this magic was, she could feel in her heart that it wasn't going to harm Flash.

"You must have awakened something inside of you," Twilight told him. "But why now?"

The other mares moved over, looking curious at him as Pinkie spoke up. "Well he did just cum inside you. Maybe that has something to do with it?" Twilight placed her hand on her stomach, whilst the light began to die down. But Flash could still feel the power within him.

"Does seeding alicorns do something to a stallion?" Rarity asked, focusing on Twilight. But the mare was clearly unsure. Cadance had never mentioned anything about this when she and Shining were together. If it had happened to Shining, wouldn't she have mentioned it?

"I don't know," Twilight explained. "I'll have to ask Celestia and Cadance about it to be sure."

"Good idea," Flash nodded before smirking. "But you can ask them tomorrow." He moved back towards her and kissed her again. "I'm not finished with you yet. We're not leaving this room until tomorrow morning. Actually, make that tomorrow afternoon. You want to get pregnant and I'm not gonna stop trying to put a baby in you, until I can't go any longer. And I'm still raring to go."

Twilight panted, as she stared up into his eyes. Something had changed in him. She could feel it. Whatever magic had awakened within him, it was making his voice reverberate with authority. If she was a regular pony, she would have probably shivered and instantly submitted to him.

The way he spoke was no longer with the voice of a pony that had simply captured a princess' heart. It was the voice of a pony that commanded the respect of those around him. A leader.

And as Flash began to make love to her again, which would evolve into a full on fuckfest, Twilight gasped as she noticed his cock felt even larger than before. And she had a feeling it would be able to shoot twice the cum he used to unload, which would all end up directly within her.

By the time the sun rose the next morning, Princess Twilight's stomach would be bloated enough to be mistaken for pregnant. The mare would spend the entire night, getting screwed out of her mind. And Flash wouldn't feel the least bit exhausted until that same point. He, Twilight, the mares and his clone would all have a night none of them would ever forget. And it would be the first of many.

Flash and Twilight's true adventure together was only just beginning. The adventure of a stallion that couldn't be satisfied with just one mare, and the one mare more than happy to share him. The duo would spend many decades together, letting each other's kinks run wild.

For as long as the two would live, which would be a very long time.

Author's Note

Happy Christmas Eve. Hope this finished story improves it. Now Flash has finally impregnated every alicorn princess. And it seems doing so caused something to happen to him. But what? You'll have to wait and see.
