A MLP Spike WG Story

This is my first ever fanfic, so I need constructive criticism about what I can improve on. I have read every weight gain fan fiction I can get my hands on, so I think I'm ready to try my own.

The beginning

   "Twilight!"

"What is it, Spike!"

"You just got a letter from Princess Celestia. I spit it out in my cereal," the little purple dragon replied.

Twilight Sparkle, Princess Celestia's favorite student, appeared in the kitchen with a flash of pink light. She grabbed the letter from Spike's claws and began to read:

My faithful student, Twilight Sparkle,

   If you have been reading the newspaper lately, you have noticed that gem eating contests have gotten very popular among Equestria's dragon communities. This is not a problem, however, it has caused a rise in the dragon obesity rate. As my most focused and well-read student, I am giving you the responsibility of conducting a spell that will allow dragons to continue their gem eating contests with no effect on their health. I would not give you this task if I did not think you could do it.

Sincerely,

      Princess Celestia.

"What was the letter about, Twilight?" Spike questioned over a mouthful of cereal.

"Oh, it was nothing. Just some friendship stuff," Twilight lied. She already had a plan forming in her head.

One week later...

"Week one," Twilight wrote in her journal, "my test subject, Spike, has been oblivious to his new diet. I have  been feeding him the most fattening and sugary foods I can get, but I don't see any visible changes."

Spike had just gone to bed, and Twilight was in her lab writing in her "Operation WG Spike" notebook. As soon as she had read the Princess's letter, she had gotten to work getting as many unhealthy treats as she could reach. Then, she had started feeding them to Spike. Her plan was to fatten up Spike as much as she could, then, try the weight-loss spell. But so-far, their were little to no results. A whole week had passes since Twilight received the letter, and ever since, Twilight had been feeding Spike nonstop. She constantly offered him treats, and when he was asleep, she used her magic to make him chew. But the only thing that resulted in her hard work was a tiny bit more chubbiness in Spike's cheeks. "Well, I'll keep trying and it will eventually show," Twilight thought to herself before climbing into bed.

Two Weeks later...

"Twilight, what's for breakfast?!?"

Spike waddled into the kitchen, his belly jiggling with every step. A week ago, Twilight had realized that a dragon's most fattening food is gems. That had really turned the gaining on. Now, Spike had a double chin forming, and he had an enormous belly that shook with every step. Twilight had also used a digestion spell that caused digestion to happen immediately when the food hit the stomach, and it turned it straight to fat. Now you could literally watch as Spike's belly grew with every bite of food.

"Man, am I hungry!" Spike said as he sat down to a big table of fattening food. There were stacks apon stacks of pancakes, drowned in syrup, all of the muffins at sugar-cube corner, each with a unique flavor, and most importantly, gems that reached the size of boulders scattered at random around the kitchen. Spike also knew the cabinets were stocked full of treats and even more gems.

He had been somewhat curious about Twilight's new diet for him, but he was too happy to worry about it. He glanced over at Twilight, and for the first time noticed that she had also put on a little weight. It was no doubt from snacking on the things she was serving Spike. Her cutie mark was a little larger than previously, and her originally slim stomach at a slight bulge to it. Spike dismissed that immediately and dive into his feast. Within a few minutes, all that was left of the feast was some crumbs and a few smeared splotches of syrup. Spike was asleep, his head lying on the table and a gem still clutched in his chubby fingers.

Chapter 3: Rarity's boutique

Chapter 3:

Rarity had been warned of Spike's new diet by Twilight, so she had laid out a banquet of her finest gems, being the element of generosity. Nothing could have prepared her though, for the sight that met her eyes when she opened the door to her boutique. "Spike! *gulp* My you look fine today! Come right in!" She led him into the dining room, were she had one spindly chair awaiting her. The same style chair braced itself for Spike's weight. Before Spike entered the room, Rarity quickly levitated a thicker, sturdier chair over to the table and switched them out. Spike waddled into the room, and his jaw dropped, causing his chubby cheeks to wobble. "Rarity... You did this for me?!?" He stammered. He quickly hopped into the sturdy chair, which creaked under his weight. He then started to eat. Rarity watched, somewhat disgusted, before beginning her brunch of a small salad and a blueberry muffin. Spike had cleared every sign that there were any gems in the room before Rarity even finished her muffin. Every platter was licked clean, every shard lapped up. Spike was passed out on top of the remnants of the chair, his packed tight stomach gurgling as it attempted to digest the feast. Rarity forced herself to watch as the spell activated and slowly started pumping gallons of quivering fat onto Spike's body. First his stomach plumped a foot or so, then his chest a few inches, and that double chin finally came in, bringing another with it. His arms thickened, and his fingers too, whilst his legs became even more squishy. Finally, Spike's digestive system slowed down and Rarity was able to levitate him over to her fainting couch. The couch legs collapsed under his weight and some flab hung over the edge, but other than that it was fine.

Spike awoke on Rarity's fainting couch, his stomach growling. He rolled off the couch, but luckily his jelly cushioned his fall. His button down shirt was ripped open, revealing his enormous belly. His pants were also ripped down the back and the waistband was demolished. He discarded what was left of his suit (he usually walked around naked anyway, except for special occasions) and made his way out the door to Apple Buck Acres.

Chapter 2

Chapter 2:

Spike awoke two hours after the feast, but for some odd reason, he had no idea it had happened. He was in his bed as usual when his stomach gave an unearthly growl.

"Ok ok! Hold on just one second tummy!" Spike said, stroking his large stomach as he spoke.

"You'll get breakfast in just a second."

He struggled to sit up, as his tummy

Gurgled and jiggled with the pressure. "Hang in there!" He told his hungry stomach affectionately. After about five minutes of struggling, Spike finally was able to sit up and hoist himself over the rim of his basket. As he contemplated what he was going to get for breakfast, he suddenly remembered he had a date with Rarity. He immediately went over to the small trunk he kept against the wall that held his few accessories and special belongings, including his most prized possession; a picture of Rarity. He grabbed his neatly ironed suit that was lying by his basket and began to put it on. The pants fit on ok until they reached his waist, which had grown considerably since the experiment started. He struggled to squeeze them over his jiggling and complaining stomach for a good five minutes, then sucked in his breath as much as he could and slid them on. He slowly eased out his breath and, hearing the popping of a few threads, relaxed. His pants bit uncomfortably into his waistline, giving him a muffin top that stretched a good 2 inches out in front of him.  After this struggle, he took on his button-down shirt. Again, this was fine until he got to the part of buttoning it over his stomach. All that stood in his way was a pile of jiggling, sloshing blubber erupting from his midsection. He did manage to button up the shirt whilst sucking in as before, but their were ovals of jelly escaping in between the buttons. He slipped on his coat and did up his bow tie, then made his way downstairs and out the door.
