Getting adjusted

As the teal girl woke up, Magic Flame backed up into the kitchen.

I'll give her some time to settle and figure out a name, Magic Flame thought. And she might not like to see me as soon as she wakes up. Besides, I should get dressed. As Magic Flame got dressed in the clothes lying on the floor, he listened to what was happening in the room next to him. As he pulled his pants up, he could hear the girl say "Hello?"

"Yes?" Magic Flame asked. "Is anything wrong?"

"No, just wondering if you were awake yet," she said. "Have you figure out a name yet?"

"Magic Flame," Magic Flame said. "Who are you? That was a lot of ponies that fused into you."

"It's fine," the girl said. "It is a little disorienting, though, but I'm fine."

"Have you chose a name?" Magic Flame asked.

"I think I'm going to go with...Spectrum Shine," she said.

"Spectrum Shine?" Magic Flame asked. "Let me guess, you couldn't decide on a name like your last fusions?"

"If you mean one that would take an aspect of one of the ponies in the fusion in one word, you're right," Spectrum Shine said. "Those were only two ponies, and three ponies would be easier to make a name for, but eleven? That's difficult. Besides, this experiment is to see if I can get pregnant, so why not?"

"Good point," Magic Flame said. "Anyway, why don't you get dressed, then maybe we could go do something."

"Ok, hang on a minute," Spectrum Shine said. A minute and a half later, the kitchen door opened up, revealing Spectrum Shine in Luna's shirt and Rarity's pants. The pants looked a little tight.

"Uh, I'm going to have to stop by the Carousel Boutique," Spectrum Shine said. "These aren't quiet my size."

"The shirt too?" Magic Flame asked. Spectrum Shine nodded, and Magic Flame 'Pfft'ed. "No way. It doesn't look tight."

"Believe it or not, it is," Spectrum Shine said.

"Let me guess, around the sleeves?" Magic Flame said.

"My boobs," Spectrum Shine said. "It's tight around my boobs." Magic Flame's cheeks reddened.

"Ok then," he said. "Anyway, besides from that, what plans do we have for the next week?" Spectrum Shine shrugged.

"Whatever, really. Actually, isn't Spike's boys night with Discord and Big Max tonight?" she asked.

"Yes," Magic Flame said. "I was kind if hoping to go to that. Could I?"

"Yeah, I don't have anything planed," Spectrum Shine said. "And who knows, maybe you can convince Big Mac to fuse with you!" They laughed.

"How serious are you about that?" Magic Flame asked.

"Well, Applejack really doesn't want Big Mac in this, but he could give the baby certain genetics that would be nice," Spectrum Shine said.

"So is that a yes or no?" Magic Flame asked.

"Ah, I'll figure it out later," Spectrum Shine said.

Later, Magic Flame had just finished putting on one of Spike's jackets, and called out "I'm about to go! Do you want me to convince Big Mac to fuse with us?"

"Yes!" Spectrum Shine called out. "But not Discord, I don't want him! Have a good time!"

"Ok, see you later!" Magic Flame said. He opened the door, and then started charging his horn for a teleportation spell. Once it reached its zenith, he casted the spell, and in a flash, he was in the Apple barn (they switched locations each time for the game to keep things interesting).

"Big Mac, I'm here!" he called out. Big Mac's head was suddenly poking out from behind a corner.

"Who are you?" he asked. "What the hell are you doi-"

"Hey, it's me, Spike!" Magic Flame said. "Kind of. Remember that letter I sent you earlier? That one about the fusion spell?" Big Mac slowly nodded.

"So, you're Spike fused with who else? A deer and a unicorn, by the looks of things," Big Mac said. Magic Flame turned the corner and saw the table with the O&O stuff on the table.

"A changling, actually," Magic Flame said. "Thorax and Sunburst." Magic Flame and Big Mac sat down.

"Thorax. That was the changeling who convinced almost all of the others to give love, right?" Big Mac asked.

"Yes I am," Magic Flame said.

"Nice," Big Mac said. "So, all we need now is Discord, and we're ready to start."

"Yeah, but before that, I have one more question," Magic Flame said. "Do you want to fuse with me?" Big Mac raised an eyebrow.

"Really?" he asked. "Why me?"

"Well, I'm having sex with a fused form of Twilight and her friends and the princesses," Magic Flame said.

"The princesses?" Big Mac said, clearly impressed. "Even Princess Cadence?" Magic Flame shook his head.

"She still needs to rule over Equestria," Magic Flame said. Big Mac slowly nodded.

"Ok, and when you say Twilight's friends, who is that including?" Big Mac asked.

"Trixie, Starlight and Sunset Shimmer," Magic Flame said. "I'm not fully sure why Trixie was there, but Sunset Shimmer was able to talk to her principals and got out for the next 9 months, so that's cool." Big Mac nodded.

"What I more specifically was asking that for was because of Applejack," Big Mac said. "Is she in the fusion?" Magic Flame nodded.

"Yes, but Applejack is just one of eleven, and if you fuse with us, it would be one of four," he said. "So don't worry, it wouldn't count as incest." Big Mac nodded.

"But Princess Luna and Princess Celestia are there too?" he asked.

"Yes, and the fused form of them all is quiet good looking," Magic Flame said. "She's named herself Spectrum Shine."

"Huh," Big Mac said. "Well then, sure!" Suddenly Discord appeared and started clapping.

"Oh, excellent choice!" he exclaimed. "Sex with the princesses! Congratulations on the both of you! Or would it be the four of you?"

"How long have you been standing there?" Flaming Intelligence deadpanned.

"Only a minute," Discord said. "But anyway, how can I get chosen?"

Getting to heat week

Later that evening, Magic Flame returned home. With Big Mac already fused into him. Magic Flame looked almost the same, but a bit taller and buffer. He also sounded the same.

"Spectrum Shine!" he called out. "I'm back!" Spectrum Shine appeared from around a corner and grinned.

"You convinced him, right?" she asked. Magic Flame nodded.

"Despite that, I'm not actually that much different," he said. "Just a bit taller."

"And more athletic," Spectrum Shine purred. Magic Flame grinned.

"You bet I am," he replied in a seductive voice. "But you won't get any of this until heat week."

"Aww," Spectrum Shine playfully whined. "Well, I'm looking forward to it."

"Good," Magic Flame said. "So am I." For the next few days, Magic Flame and Spectrum Shine got used to their fused forms and planned for the heat week. Of course, the Trixie and Luna in Spectrum Shine really wanted to have sex then, but the Applejack in Spectrum Shine was more than enough to make her stop. But then, heat week finally arrived. Spectrum Shine knew that when she woke up, and her bed sheets were soaked with her arousal. She grinned happily as she walked down stairs and saw Magic Flame making pancakes.

"Oh, Magic Flame!" Spectrum Shine called seductively. Magic Flame suddenly straitened and turned around.

"Yes?" he asked.

"It's started," Spectrum Shine said. "We'll eat first, then we can get to the part we've been waiting for." Magic Flame grinned.

"Come on down, then," he said. "We can already start with our breakfast."

After they had finished with their pancakes, Spectrum Shine had scurried upstairs to get ready. She teleported her clothes into the bathroom, and lied down on the bed, her legs spread wide, and her breasts on display.

"Come in," she said. The door opened and in walked Magic Flame. He gazed upon Spectrum Shine, a sparkle in his eyes. He started taking his pants off, but Spectrum Shine teleported his clothes off instead.

"How do you want me to do this?" Magic Flame asked.

"Stick it in," Spectrum Shine said. "Suck my nipples, slap my ass, I don't know. Do what you want with me. I'm yours." Magic Flame's already hard erection got harder. It was already a foot long, and quite thick. So he walked up to her, and inhaled her neathers. He jumped onto the bed, and then stuck it in. Spectrum Shine screeched.

"Are you ok?" Magic Flame asked.

"Yes, apparently my hymen was there," Spectrum Shine said. "Just keep pounding!" And so he did. Magic Flame's rock hard dick continued to slid in and out, in and out, making Spectrum Shine moan and screech. She was in heaven. And what happened next surprised her. Flaming intelligence suddenly picked her up and slammed her into the wall. Somehow, that allowed his dick to go in deeper. And she loved that. She screeched and screeched. And then finally, he started suckling on her nipples. He coated her right nipple in his saliva, licking and flicking it with his tongue. And of course, there was the sucking itself. She didn't think she could ever surpass pleasure like this. However, she could feel her climax approaching.

"I'm gonna-ah-cum!" she yelled.

"Don't worry, so am I!" Magic Flame cried. "I thought I was going to last longer than this!" And then they came in harmony. Magic Flame's cum filled Spectrum Shine 's womb, making her already appear pregnant. They dropped to the floor, panting heavily, covered in sweat.

"That was great," Magic Flame said.

"Definitely," Spectrum Shine said.

Heat week had finished. Spectrum Shine and Magic Flame did have sex a couple more times, but she was pregnant. And that was the important part. And Cadence and Shining Armor had come to talk to them about the baby. Cadence was telling Spectrum Shine some tips and what to expect.

"Your ankles will swell, so you should get some shoes that are a size bigger. Also, your morning sickness will not be good, so you might want Magic Flame to be with you to help hold back your hair. Shining Armor did with me when I was pregnant with Flurry Heart."

"And what if Magic Flame doesn't do this?" Spectrum Shine asked. Cadence grinned.

"Well, just do what I did. Threaten to embarrass Flaming Intelligence with anything he did during your sex," Cadence said. "Shining Armor has some embarrassing fetishs." Shining Armor started to blush.

"Yes, it was effective," he said. "Or you could just make him sleep on the couch. That's also effective." Spectrum Shine and Cadence giggled.

"Well, either way, I can't wait till I give birth!" Spectrum Shine said. "Staying in the same fused form for the next 11 months is going to be interesting."

Author's Note

I am so sorry that this took this long to get released. I thought I had pressed the publish button earlier. Anyway, I hope you enjoy!

Leading up to the birth

Later that week, from Cadence's advice, Spectrum Shine and Magic Flame went to get a sonogram. As the doctor placed the sensors on Spectrum Shine's belly, he asked about hopes for the child.

"Is this your first?" he asked first.Spectrum Shine and Magic Flame nodded.

"Any plans on his or her future?" the doctor asked.

"Not really," Magic Flame said as Spectrum Shine said "Yes." They stared at each other.

"You don't have plans?" Spectrum Shine asked.

"Well, not about what job he'll be in," Magic Flame said. "Whatever he wants to be is what he wants to be, and I'm good with that. What are you planning?" Spectrum Shine crossed her arms, just under her large bust.

"Well, he's going to get a good education and become something really important," she said with a frown. "Like an epic stunts-man or some kind of doctor." Magic Flame shrugged.

"Well, either way, I'm supporting him," he said. Spectrum Shine smiled.

"You're so sweet," she said. She turned to the doctor. "What gender is it?" The doctor was looking confusedly at the screen.

"Well, it's male," he said slowly. "But there's something strange about it."

"Strange how?" Spectrum Shine asked, eyes widening in fear.

"The sonograph keeps glitching," the doctor said. "He looks like a cross between different species. Plus, one second he's in one position, then the next second he's in another."

"That is pretty weird," Flaming Intelligence said. "But he's ok?"

"Oh, yeah," the doctor said. "He's perfectly healthy."

11 months later

Spectrum Shine was giving birth. Magic Flame was pacing outside of the room she was in, glancing at the door every time Spectrum Shine screamed, which was often. This took almost another half an hour, but finally, the door opened and one of the doctors exited the room. He looked at Magic Flame.

"You're the father, right?" he asked. Magic Flame nodded. "Then congratulations! You've got a kid!" The doctor widened the door and Magic Flame entered.Spectrum Shine was holding a tiny blanket with a small baby inside. The color of the fur, if it even was fur, was a deep, midnight blue. His eyes were closed, and he had a horn. Spectrum Shine looked up at Magic Flame with bloodshot eyes, her face soaked with sweat and tears, and smiled.

"He's got your skin," she said. "A mixture of scales, chitin and fur."

"You're already studying him?" Magic Flame asked. "He was just born!" Spectrum Shine giggled.

"Yes, and he's a miracle," she said. "He's an alicorn, by the way."

"Oh, that is awesome," Magic Flame said, his smile widening. "He's an alicorn. It really is a miracle."

"Oh, how many people are waiting outside?"Spectrum Shine asked. Magic Flame sighed. Several months after Spectrum Shine got pregnant, word got out that she was the combination of three princesses, and the reporters were on the story like flies on a dead body. After a few days of being pestered, Spectrum Shine finally gave in, and told them that she really was all three princesses, with the rest of the Elements of Harmony and a few others. And because of that, the hospital was packed with news reporters and whatnot.

"The hallways are packed," Magic Flame said. "It's a miracle that the waiting room was empty." Spectrum Shine was still for a few seconds.

"I'll teleport us home, then," she finally said, before turning to the lead doctor. "It's safe for me to teleport him, right?" The doctor nodded.

"Yes, but before you do, we need a name," he said. Spectrum Shine thought for half a minute before smiling.

"Amalgam," she said. "Now, we'll see you in about a week or so for his check up, ok?" The doctor nodded. Spectrum Shine smiled, nodded, and her horn light up. A few seconds later, a bright light flashed, and they were back at the castle. Apparently, ponies had been waiting outside of the castle, looking in through the windows, because they soon heard cheering. Spectrum Shine scowled and magicked the windows close. Magic Flame frowned.

"Why did ponies have to wait out here?" he said aloud. Spectrum Shine shrugged.

"Let's not focus on that now," she said. "Instead, let's get Amalgam up to his crib. I need to get you back into your original forms anyway." She had said that last bit to Magic Flame. He was surprised.

"Wait, why?" he asked.

"Because first of all, Big Mac needs to get back to the farm," Spectrum Shine said. "Granny Smith and Apple Bloom have gotten a lot of help without Big Mac and Applejack there. And second of all, it'll help to have Spike, Thorax and Sunburst here to help keep Spectrum Shine safe."

"What about you?" Magic Flame asked.

"I need to stay as Spectrum Shine for a while more," Spectrum Shine said. "For at least another month or so. Probably longer than that, though." Magic Flame sighed, but nodded. He didn't like it, but he knew why Spectrum Shine needed to do it.

"Do it," Magic Flame said as he magicked his clothes off. Spectrum Shine's eyes traveled up and down his body for a few seconds before she started charging her spell. As Magic Flame mentally prepared himself for the split, Spectrum Shine casted the spell, bringing all four different people that made him up apart. As Spectrum Shine released the spell, all four people fell to the ground. After 11 months, he was finally 4 different people again. Spectrum Shine needed to remain as she was for a while longer, though. She smiled down at Amalgam as he woke up and started to coo.

One Month Later

It had been roughly a month since Amalgam had been born, and he had been talked about in the news a lot. A lot of ponies had asked about when Spectrum Shine was going to defuse back into all of her normal forms, like Magic Flame had. And during that month, Spectrum Shine had discovered something fascinating. Amalgam was able to defuse. Spectrum Shine had been reading one of the news articles about Amalgam, and someone had asked if Amalgam was able to. So, Motherly Perfection decided to find out. She had felt guilty, but when Amalgam had actually split into (suprisingly) 12 different kids, Spectrum Shine had been glad she had done it. Spike, Thorax, Sunburst and Big Mac had all found that fascinating, and they all decided that the best course of action (for now, at least) was to keep them all as Amalgam.

Finally, it was time. Spectrum Shine had been looking forward the day she would defuse for a long time. She didn't know how this would effect Amalgam, but if there were any emergencies that needed Spectrum Shine, then everyone making her up would be called. Spike was in the room with her as she undressed, to catch the clothes and put them in a hidden closet in Rarity's house, and he had a set of clothes for each of the girls that was going to come from the defusion. Spike's eyes, of course, were drawn to Spectrum Shine's large chest and rear, but she let him look. After all, it was going to be gone soon.

"You excited?" Spike asked. Spectrum Shine nodded.

"I've been Spectrum Shine for a year now," she said. "And while it's been great, I can't wait to return to some of my individual lives." Spike nodded.

"I know that feeling," he said. "I do miss being Magic Flame, though." Spectrum Shine snickered.

"Let me guess, because of your foot long?" she asked.

"Hey, I already have a foot long!" Spike said, his masculinity being threatened. Spectrum Shine's eyes widened in mock suprise.

"Oh, really?" she asked. "Then perhaps you can help the Great and Powerful Trixie next week." Spike frowned.

"Wait, isn't that heat week?" he asked. Spectrum Shine nodded. It took Spike a few seconds to fully get the message, but when he did, his eyes widened.

"Oh," he said. His mouth curled into a grin. "Ok." Spectrum Shine smiled and nodded.

"Well, then, in that case," she said, her horn charging the defusion spell. "I will see you in a little while." And she released the spell, bringing the 11 ponies that had formed Spectrum Shine for almost a year, apart. Finally. As the ponies all collapsed into a pile, Spike found Twilight at the top, and dragged her off of Fluttershy and Rarity. For several minutes, he dragged and dropped the girls off near their clothes, and when the Twilight started to move and wake up, Spike quickly exited the room, not wanting to anger any of them, just in case. The rest of the day went on pretty smoothly, with Spike helping Twilight schedule when one pony would take Amalgam, and for how long (a full day at the most). Trixie came up and thanked Spike for all the help, and for promising to help her with heat week. She promised him that she would please him greatly.

As the day progressed, a problem arose. As it turned out, Fluttershy was the only one who was lactating, and that was a problem. So Fluttershy promised to fill up several dozen bottles with her milk. They all agreed that it was better than formula. As Celestia lowered the sun and Luna raised the moon, everypony started going to their homes, with Fluttershy taking Amalgam home with her. As Spike climbed into his bed, Twilight appeared next to him in a flash of light, completely naked. Blood started rushing to his face, among other places, as he turned away from Twilight.

"Hey, I just came for cuddles," she said with a pout.

"Without clothes on?" Spike asked. "What did you want to cuddle?"

"Hey, this is the first time that I've been alone with you," Twilight said. "Last time we cuddled, I was a part of Spectrum Shine." Spike grumbled a little, but finally turned over again and opened up his bedsheets.

"Fine, come lie down," he said.

"Yay!" Twilight said with a giggle. The rest of the night was soft and warm. But the rest of their life had just begun.

Author's Note

Well, this is the final chapter of this story! There will be more fusion stories in the future. Some of them will be prequels, and some of them will be sequels. Either way, I hope you like them, and this one! Until then, have a good day!

Getting fused

Finally, it was almost heat week. Twilight had been excited for this for many reasons, mostly it being the possibility of pregnancy. She had invited her friends and the princesses over for the fusion, and Spike had sent letters to Sunburst and Thorax. They were going to fuse a week before heat started so they knew that the new and improved spell worked. Someone knocked at her door, and Twilight almost tripped running to open it. It was Spike.

"Hey, everyone is ready and downstairs," he said. "Are you ready?" Twilight nodded.

"Thank you," she said. "You better be ready." Spike snickered and led Twilight to the Cutie Map. The princesses were there, her friends were there, including Sunset Shimmer and Starlight, Thorax and Sunburst were there, and for some reason Trixie was there. Twilight decided to address that first.

"Why are you here?" she asked Trixie.

"Because the Great and Powerful Trixie desires to be part of this experiment!" Trixie exclaimed. Twilight stared at Starlight.

"What did you tell her?" Twilight asked.

"Hey, she asked what I had planned for heat week and I told her about this," Starlight said. "I didn't know she would want to join us! Not that it'll be a bad thing, though. Let her join us."

"Ok, fine," Twilight said. She walked over to her chair and stepped up onto it. "Ok, everyone! We need to talk before the fusing starts!" Everyone stopped talking and stared at her. "Ok, before we fuse, are all of you ok with doing this? We will be having sex later on, and we are aiming for pregnancy!" Everyone said yes. "Ok, now that we got that out of the way, are we sure about the set of genetics that the baby would be receiving? Do we want to add or subtract anypony?"

"Is Trixie in this?" Starlight asked.

"Yes, Trixie is in this!" Twilight said. "Do we want to add anyone? Like any more males? There's only three."

"How about Big Mac?" Spike asked.

"NO!" Applejack yelled. "Do not add Big Mac!"

"Haha, don't worry, I'm kidding," Spike said. "That would be weird."

"Good," Applejack growled. "It would be weird."

"Are you sure?" Celestia asked. "I wouldn't mind at all if Big Mac joins us."

"Me neither, actually," Luna said.

"We're not adding Big Mac," Applejack said.

"Why not?" Luna playfully said. "We're fusing together so many mares, it probably wouldn't count as incest. Would it, Twilight?" Twilight shook her head.

"It wouldn't, but seriously, is there anyone else we would like to add?" Twilight asked.

"I think their fine," Luna purred. "Why is it that we're fusing a week early, again?"

"We need to make sure that the new spell works, especially on the scale that we're doing it on," Twilight said. "I don't know what would happen if we defused while pregnant, but it would probably be bad." Luna nodded.

"Ok then," she said. "Now, who's going to be fused first?"

"They are," Twilight said, nodding at Spike, Thorax and Sunburst. "So, go into the next room, and get undressed. I'll be there in a minute or two to fuse you together." The boys nodded and exited through the door that Twilight had indicated.

"Now, while they get ready, are there any other questions?" Twilight asked. Celestia raised her hand.

"Is Cadence really going to be the only one running Equestria?" she asked.

"Shining Armor is going to help her, but we might go do it from time to time. Although we probably shouldn't let the public know that this is why the princesses have disappeared," Twilight said. "That might cause problems. Especially scene so many princesses are involved in this." Trixie raised her hand.

"How long is the fused boys dick going to be?" she asked. Twilight blushed.

"I don't know," she said. "But I was told that Shining Sensor's penis was 11 inches erect, but that was Thorax and Sunburst's fused form. Adding Spike to the mix could shorten the length." Suddenly there was knocking on the door of the kitchen, where the boys had gone.

"Twilight, we're ready," Spike said. Twilight grinned.

"Good," she said. She quickly opened the door, entered the room, and closed it again. She turned around to see the boys all in the center of the room, and she started charging the spell.

"This won't hurt, will it?" Spike suddenly asked.

"No," Thorax and Sunburst responded simultaneously. Then Twilight casted the spell, bringing them together in a bright flash of light. When her eyes cleared and she could see again, she saw the newly fused form laying on the ground in front of her. He was a surprisingly deep purple color, almost black. He had shiny black scale like fur, same colored horn, orange antlers, Orange hair, and purple spins jutting out of his back like with Spike. Twilight grinned.

Aww, yeah, she thought. This is going to be nice. Twilight exited almost as quickly as she entered, and grinned.

"It has been done," she said. Twilight started taking her shirt off. "Now, everyone, get undressed." A few minutes later, all the clothes were lying in a pile in a corner.

"Is everyone ready?" Twilight asked. As everypony said yes, Twilight started charging the spell, mentally preparing herself for what might happen after they all fused. Then she casted it, bringing everypony in, and blacked out as they all met. Meanwhile, in the kitchen, the fused form of Spike, Thorax and Sunburst woke up. He rose from the ground and looked at his skin, and other wise checking himself out.

I have abs, he thought. Nice. His stomach gurgled, and let out a massive burp, green fire spewing from his mouth at a length that Spike had never done before. He grinned.

Nice, he thought. Hmm, what am I going to call myself? He sat and pondered that for a minute before deciding on a name.

I'll go with Magic Flame, he thought. I wonder if the girls have fused together yet? He opened the kitchen door and saw a large chested, large rear ended light teal girl lying on the ground, face up. She had flowing multihued yellowish hair.

They've fused, Spike thought with a grin. The girl started to stir, and opened her eyes.
