Author's Note

Sorry about the long wait, had to deal with some troubles at home, but here is the second chapter finally!
Hopefully, I will start updating this story more often so I hope everyone enjoys it.

The First Step

Spike woke up with a start, only to be blinded by the intense morning light coming from his window. He always hated having the most east-facing room in Twilight's castle, but it was outweighed by how many chores he could get done even before the Apple family awoke. Right now, however, he wished he could sleep in for the next few days; his body felt like lead and his mind was swarming with thoughts about his strange dream last night.

Even with how creepy the last part was, what with having his chest ripped open and something inserted inside, what really sent his brain into a tizzy was what the stranger had said to him. He couldn't believe that Rarity, one of his adopted sister's best friends and life-long crush, was getting married, and to Blue-blood at that. Just thinking about it, even if it was just a dream, made him gag.

But sulking on that thought wouldn't solve anything, no matter how much he wished it could, and decided to start on his morning routine to try and clear his mind. As he got out of bed Spike wondered for a moment on the fact he was still wearing his clothes from last night, but quickly figured he was just too tired last night to care and had fallen asleep as soon as he hit his bed. Grabbing some clothes from his dresser he made his way out his room into the vast sprawling hallways of the Crystal Castle towards the washroom.

As he was making his way, he stumbled across Twilight talking excitedly with a pegasus wearing the armor of the Cantorlot Royal Guard. The guard's back was towards Spike, so he didn't realize who it was until Twilight called out to him as soon as he got closer, but when he did Spike instantly felt his stomach drop. Why'd it have to be him!

Standing between him and Twilight was the one guard's pony that had made his life at Cantorlot a living hell: Brash Bolder. He had been one of first few ponies to try and make Spike hatch when he was still an egg, a test to see how a magically gifted unicorn dealt with failure; sufficient to say he hadn't taken it so well and was rejected from joining Celestia's School for Gifted Unicorns. He had found a place in the Royal Guards, but when he found out that Twilight Sparkle had managed to hatch the dragon egg that he believed caused him to fail, he decided to make her pay.

He couldn't harm her, however, what with Shining Armor being his superior, so he redirected his wrath at Spike instead. Every day was a new torment for the young dragon: tripping him in the halls, filling his bed with spiders and bugs, or beatings that would've left a pony with a normal physic in the hospital. It was only when Celestia sent both Twilight and Spike to Ponyville that he was freed from Brash's bullying. But now, as Spike stared into the face of his childhood tormentor, he couldn't suppress a nervous gulp, which Brash responded to with a sinister smile.

It took Spike a few seconds to notice Twilight was talking to him, and a few more to register what she was saying due to how fast she was talking.

"--I still can't believe this is happening! I had been wondering what was taking Rarity so long at Cantorlot, but with how difficult it is to schedule a wedding, even for someone of high-standing, it kind of makes sense; also Rarity wouldn't stand for anything less than the best for her big day and would have to order so much from across Equestria. The dress alone would take her, she just has to design it herself, a couple weeks to complete, I can't imagine how she plans to get it done in three days, not to mention the process of getting--"

Even after living with the excitable mare for his entire life Spike still had trouble tuning out most of the fluff from her sentences, especially now with how her breast bounced in time with her thrilled hopping inches from his face. While the poor dragon had barely grown at all, the magically gifted alicorn before him had definitely blossomed since leaving Cantorlot; especially after getting her wings. While not as buxom or fit as her friends she was above average just enough to make everyponies, and a particularly embarrassed dragon's, head turn.

Just as he was about to say something Twilight ran off, shouting back about something to do with invitations, leaving Spike alone with his reddened cheeks. He was drawn out of those impure thoughts, however, as his mind snagged on something Twilight had said. Three days...in just three short days Rarity was going to walk down the aisle and be taken away.

With a sharp shove, Spike was taken from his thoughts back into reality, one with Brash standing over him with a wicked grin on his face. "Well, well, well. If it isn't the little pipsqueak from way back. Still the little runt I remember, aye?"

Spike tried to push past him but was again shoved back into the wall, nearly knocking over several vases. Brash had gotten a lot stronger since he last picked on Spike, his body covered with a visible layer of tough muscle and had grown to a full head taller than the short dragon.

"Where do you think you're going, lizard-colt? Running after you dear sweet sister?" Brash taunted, holding Spike against the wall with one hand whilst looking down the hallway where Twilight had left.

"Sweet indeed, though! Man, she got a good ass, a lot better than some of the tail around this shit-hole. Maybe I should stay awhile, see if she'd enjoy a nice mouthful of my dick, make her gag on it. You know what I'm saying?"

Spike was furious, but couldn't do anything about it: Brash was just too strong and he was too weak to stop him. He wished he could turn the tables on the jackass, show him what happens when you bad-mouthed his sister. Just then he felt something shift inside him, like a worm wrapping around his heart, and with a single push sent Brash crashing to the floor, only stopping when he hit the opposite wall.

"What the fuck! You little shit, I'm gonna...gonna...what?"

Spike couldn't hear Brash, his head lowered and steam seeming to pour out of his mouth with each breath, only leaving the hand he had pushed Brash away with hanging in the air palm facing him. A slow fleshy rip filled the air as a small slit opened on Spike's scaled hand, opening to reveal an eye, it's pupil surrounded by flowing red and shaped like a ten-pointed star, which rolled around in it's newly formed socket before focusing on the bully. As it focused on the Brash a wave of energy began to flow from him, in through the eye, and into Spike, both of whom began to change.

The first to feel something was Brash as his body suddenly felt ten times heavier and his mind began to get foggy. He could barely understand what was happening, if at all, as he watched his arms grow thinner and the objects around him start to increase in size. The muscles he had spent long grueling years working as a Royal Guard to obtain melted way leaving only skin and bones, his armor hanging limply from them.

On the other end of the transfer Spike felt his entire being tense up as jolts of power flowed from his arm to his heart, and then radiate outwards. His small frame shot up a couple of inches before steadily growing higher, as his body filled with strength as muscles he never knew he had inflated, bursting out of his clothes. He couldn't believe how good it felt, only barely managing to keep his tongue from lolling out his mouth from pure pleasure, but the show was just starting.

Brash panicked as his groin felt like it was being pulled inward, trying to pull itself back inside. He didn't have long to worry, however, as he felt another pulling this time from the horn on his head. Like a funnel, he could feel his magic pouring from it and into the eye, a visible stream of power flowing through the air, along with a piece of his psyche.

Meanwhile, Spike felt his mind expand, his senses becoming sharper and a small part of him growing larger. He was so focused on how his mind was changing that he didn't notice how the front of his pants began to strain with its new weight. He was only freed when he felt whatever was causing these changes die down before stopping completely.

Spike couldn't believe how amazing he felt but was even more so when he looked down at the pony kneeling in front of him. Where once would've been Brash Bolder, fit bully of a guards pony, now was less than a shadow of himself: his once sleek bulk was replaced with taught pale hide, stretched over slim bones covered in armor several sizes too large for him. Even his eyes looked duller and had lost the smugness that he was once known for. He looked so weak and helpless that a gentle breeze could knock him over...or a now enlarged dragon.

Brash didn't have long to look over his shrunken form, with a lot less emotion for someone who had had most of them siphoned away, as Spike loamed over him, his enlarged shadow completely covering the cowering figure.

"I think it's about time for you to leave...and never come back," he growled in a voice deeper than he remembered. It took a few moments, a swift kick, to get the little runt moving and frantically running down the hall as if being chased by a manticore.

After watching him scurry down the hallway, enjoying the show far more than he would've, Spike immediately ran to one of the castle's many washrooms, stripped (or rather ripped) his clothes off and stood in front of the mirror. Where before he would always dread looking at his reflection, a stark reminder of how puny and short he was, now as Spike began to admire the dragon looking back at him he could only think of one thing. Damn, I look sexy!

He wasn't very good at judging height, but if he had to guess he would say that he had grown a full foot-and-a-half taller, putting him just above average. He had filled out as well, his frame covered in a swimmer's physique, which he enjoyed flexing and posing far too much. Muscles weren't the only thing add, much to his slight annoyance, noticing that his gut was sticking out more than usual, but he figured that could just be due to the extra layer of flesh pushing it out.

Looking past his gut Spike saw something that filled him with so much glee he couldn't help giggling like a school foal: his enlarged member. Wrapping his hand around it, hefting it a couple times to feel how weighty it was, estimating that it was now a decent eight inches; still small compared to the pictures in his magazines and from what he saw the few times he tried to go to the gym. Reaching lower Spike found his sack had filled out to the size of lemons, the scales stretched tight over them but loose enough to let them hang nicely.

Stopping before he lost himself to his new piece, he would've spent the day fondling and jacking it otherwise and looked back to the mirror noticing some other slight changes. He swore that the colors of his scales were darker than yesterday and the spikes along his back had an increase in number and size, not to mention how sharp his teeth had become. When he went to feel their pointed tips he found that his nails had grown as well, looking more like claws than anything else.

Pondering this development for a moment Spike was interrupted by a knock on the door. Just as he was about to open the door he realized he was still nude and quickly wrapped a towel around himself, wondering why he thought exposing himself wasn't a big deal. As the door opened revealing his surrogate sister, he began to worry about how she would react to her little dragon suddenly growing in several ways in just a few minutes.

"Hey, Spike," Twilight said, running a hand through her disheveled hair, "sorry about earlier. I was just so excited about the news, and how much I would need to do to help, and making sure that everyone knew, and who I need to call, and..."

Noticing the blank expression on Spike's face she realized she was rambling again. Pinching the bridge of her nose at how manic she could be sometimes she took a few breaths before returning to her apology. She didn't know that the reason Spike was befuddled was the fact the Twilight wasn't reacting at all to his larger body as if it was just normal.

"Sorry, sorry, it's just so much that I didn't realize that you may need some help with processing this, since...you know...you had a crush on her and...GAH! Why am I so bad at this? Either way, I just wanted to know if you're okay and if you need to talk or...?"

It took a few seconds of Spike processing about what had just happened in the last few minutes, from having a weird dream about a stranger giving him the power to drain ponies of their size and then finding out that somehow it was true, that he didn't realize that Twilight was waiting for him to say something.

"I'm...fine...Twilight. You don't need to worry about me that much. I mean, it was just a young crush, and she was much older than me anyways."

Twilight released the breath she didn't know she was holding, "that's good. Well if you need anything just let me know. I still need to talk to that guard and see if he had gone to the other girls' places to tell them. Where is he, by the way?"

"I think he went back to Cantorlot," Spike lied, surprising himself with how quickly he did. "I think he said something about being needed for a training routine. I can deliver the messages, I wanted to head out anyways."

"Thanks, Spike. That's a load off my plate, though there's still a mountain of work to do. Make sure you get a new suit too, something special for the big day. Everything needs to be ready in three days."

With that Twilight said her goodbyes before flying back down the hall towards the library leaving Spike to dwell on what she had said. Three days until Rarity's wedding and he needed to across Ponyville back and forth delivering the message to everyone. Walking past other stallions who were still bigger and most likely more endowed than he was, but looking down at his hand, with just a thought making the strange eye appear again, he couldn't help but chuckle, which sounded slightly like Brash's just minutes before.

There was going to little change in plans for the upcoming wedding!

-Phase One Complete-

The creature that had been implanted in the dragon had grown quite well since its creation just hours ago.

It had taken the entire night for it fully integrated into the spinal cord, but now it had not only a direct pathway to the dragon's brain but also a support which would make it impossible to remove without damaging the host.

Once firmly rooted it began to spread outwards, wrapping its tendrils around major organs and into the brain.

It didn't take long the host for it to find a suitable subject for the organism, which rewarded the host with plenty of endorphins and other chemicals to make the process all the more addictive.

With some of the extra essence taken from the subject, the organism began to grow more, starting to fuse itself into the host but found the energy lacking.

It doesn't matter, however, since the host would find more sources for the organism to feed on, making both of them stronger and closer together.
