Spyro the dragon listened to his belly grumble again. It had been several days since he was thrown in this dungeon. He thought back to last week when a fairy had arrived to ask Spyro to free her home isle from a strange invader. She said an army of turtles and mushrooms had descended from sky-ships and were building a fortress. Spyro and his best bud Sparx didn't know what to make of this, but accepted the request anyway and sailed off to investigate the invasion.
Upon making landfall, Spyro and Sparx fought off the turtle-like 'koopas' that had taken over the island's farms. Easy enough for the seasoned heroes. But as they closed in on the fortress, they were suddenly ambushed by koopas in blue robes. These magikoopas kept outta reach, teleporting as they waved their wands to launch sleep spells at the heroes. The spell knocked down Spyro, who fell face first into a mud puddle. Last thing Spyro saw was a chubby koopa kid standing over him with a paintbrush, then darkness washed over him.
When Spyro woke, he was in a dank dungeon, a shackle around his neck chaining him to the wall. The dragon looked around at the torch-lit walls. Sparx was nowhere in sight and there were brown shroom creatures patrolling outside his cell. Eventually, a turtle came up to Spyro, carrying a tray of vegetables and some water. Spyro was angry and frustrated and worried about Sparx. When the koopa put the tray down, Spyro lashed out and knocked it aside, demanding to know where Sparx was. The koopa scoffed and left without a word. This event played out for the next week, Spyro too proud or stubborn to back down until he had answers. 
A heavyset koopa arrives and takes Spyro's chain off the wall. "Get moving, the prince wants to see you." the koopa kicks Spyro inn the rump. The purple dragon's first instinct was to flame the dumb turtle, but he held back. A meeting with this Prince Bowser Jr was exactly what he was waiting for. He let the koopa lead him out of the dungeon and into a regal dining hall where Bowser Jr was stuffing his face with fried chicken. Well dressed butler koopa troopas were lined up against the far wall, in case Jr wanted anything more.
Spyro was made to sit next to the prince, but far enough that his fire breath couldn't reach Jr. "Where's Sparx!"
Jr looked at his prisoner as he slowly chewed his chicken dinner. "Who's that?" he said in a squeaky voice.
"Sparx! The dragonfly who was with me when I was caught." Spyro huffed smoke out his nostrils.
"Ooh, that noisy bug." Jr took another big bite while he watched Spyro's face. He knew he was getting under the purple dragon's scales and hoped to see anger in him.
The young prince continued chewing as he waited for Spyro to speak. After a moment, Spyro's belly growled. The prince's meal smelled so good that it was making the dragon's mouth water. The young prince noticed and smiled. "Hungry?" He reached forward with a half-eaten drumstick. Spyro snapped his head away to avoid the offered food.
"Not hungry," Spyro said through clenched teeth. "Just wanna know where Sparx is!"
"How 'bout this, I can't have my prisoner starve so you gotta eat. And if you do, I'll let you see your bug buddy," Jr tossed the drumstick at Spyro's feet.
Spyro stared at the chicken while he thought things through. This was progress. Spyro bent down to eat, though it was a bit gross to be eating the brat's leftovers. Jr watched Spyro eat as he munched on the drumstick, occasionally tossing another piece at the captive's feet. 
"Oh by the way, you have to eat everything I give you." Jr got up and placed a plate of veggies in front of Spyro. "I don't like these, so you hafta eat 'em."
Spyro looked up at Bowser Jr, thinking what a spoiled brat he was. But he was hungry enough to not argue and finished the plate. "Can I see Sparx now?"
"Not so fast. I got a lotta leftovers you can help me with first," Jr waved to some butler koopas and they left to get several trays piled with food. Mostly fruits and vegetables that Jr didn't want for himself.
"How in the world am I supposed to eat all that?" Spyro said as the trays were placed on the floor around him.
"Just start eating." Jr was served a tray of fresh food and started eating again, ignoring Spyro.
The purple dragon sighed and started in on the plate. It tasted good enough, but it didn't take long before he couldn't fit any more into his stomach.
After finishing, Bowser Jr sat back down and wiped his greasy fingers on a napkin. "I said you have to to finish it all." Jr stood up and walked towards Spyro. He gestured to the heavy koopa holding Spyro's chain. "Hold him down, I'm gonna hafta force you to eat."
Spyro growled as the koopa guard planted a heavy hand on his shoulders, forcing him to the ground. Spyro tried to flame Jr, but after days starving in the dungeons he lacked the strength to produce anything more than smoke. That caused Jr to cough, but didn't stop him from prying Spyro's mouth open. Spyro struggled to get away, but he was held firmly in place by the two koopas.
"Hm there! Now start shoving food in him." Jr said. A butler crouched down and picked up handfuls of old food. but he hesitated to put his hand in the dragon's mouth. "Go on... We have to clear out these leftovers and I was taught better than to waste food." Jr said. The scared butler carefully placed the food in Spyro's mouth and snapped his hand back out. Jr followed up by shutting Spyro's mouth and holding it shut with a surprisingly strong grip.
Spyro was forced to chew and swallow the mouthful. Once Bowser Jr was sure, he forced open the dragon's mouth and repeated the stressful process for nearly an hour. By the time he was done with all the leftover food on the plates, Spyro was exhausted. He couldn't even get off the floor, his legs felt like jello. He panted and burped a little to relieve the pressure in his bloated stomach.
"That's a good boy." Jr patted Spyro's head as the dragon drifted off into a food coma.
***
Spyro awoke some time later, back in the dungeon. He blinked and saw the koopa guards still watching over him. "What happened?" The purple dragon said as he rubbed his eyes.
"You passed out from overeating. The prince sent us to fetch you as soon as you woke up." one of the heavier guards grabbed Spyro's chain and escorted him to the throne room where Jr was waiting. The large windows along the top of the walls made it clear that it was nighttime.
"You know, little dragon, I know who you are," Jr said. "The farmhands told me that you're some sorta hero. So I was thinking about how I could bring you down a peg." Jr clapped and a butler brought in a cart of more food. "I'm gonna to make you into my personal pet. And I'm gonna keep feeding you until you're unrecognizable."
"This wasn't the deal!" Spyro yelled as they walked past. His stomach and jaw were still sore from that afternoon. "I ate your stinkin' leftovers, where is Sparx?"
Jr walked behind the throne and picked up a small bird cage, presenting it to his prisoner. Inside was Sparx, looking a healthy yellow colour. "See, your dumb bug is fine." Jr put the cage next to the throne and walked over to Spyro. 
"Let him go! Mmff!" Spyro said right as Jr grabbed his muzzle and the guard koopa held him down. Jr laughed as Spyro struggled to get free. Spyro was back to being force fed.
Jr opened Spyro's mouth and the butler went to work putting food in the angry dragon. "Lets see... I'll consider freeing Sparx if you behave." Jr said."I'm not heartless, you might learn to like being my pet."
Spyro glared at him. 'No I won't!' he thought. 'I'm not gonna eat another thing that stupid prince gives me.' Spyro tried once more to breath fire and managed it this time. A jet of fire hit Jr in the face, but Jr quickly shut the dragon's mouth causing the flames to spill out of Spyro's nostrils.
"You dare!" Jr didn't seem to be hurt by the quickly extinguished flames. "That's not gonna work on me. If you ever wanna see your friend go free, stop resisting."
Spyro glared at Jr and struggled harder in his restraints. It was starting to look pointless, so Spyro relaxed and cooperated with the force feeding. He would have to think of a new strategy later. For now, he needed his strength back to escape this mess.
***
Another week passed since Spyro had been captured by Jr. He had gotten used to his daily feedings, and his body was beginning to adjust to the constant overeating. At first he had passed out after every meal; now he able to stay awake, albeit still feeling drowsy.
Spyro was struggling to come up with an escape strategy. If Sparx were freed, then he could've stolen the cell keys. But Jr was still refusing to free Sparx, at least he was taking care of the dragonfly. The constant meals left Spyro feeling sluggish, and they were starting to have an effect on his figure. His athletic figure was softening up gradually.
It was yet another day of feedings. Spyro was escorted into the dining hall where Jr was finishing his own breakfast. Jr hopped down and moved to grab Spyro's jaw, but Spyro was tired of his jaw being sore all the time and opened it up himself.
"Hey, that's right," Jr patted proudly Spyro's head. "You can open your own mouth. That makes things easier for both of us." Jr started stuffing food into Spyro himself. It wasn't leftovers this time since the dragon had eaten all of that already. His meals this time was pancakes, eggs, sausages, and gravy biscuits. 
Spyro fell into the monotonous movement of his steady chewing and swallowing, nearly drifting to sleep by the time breakfast was over two hours later. Jr always made sure that Spyro ate enough plates of food that he would be too bloated to fight back.
When are you going to release us?" Spyro stifled a burp and rubbed his tummy.
"Not until I'm satisfied. If you keep up your good behavior, then I'll think about it." Jr sounded so smug that Spyro wished he could charge into him. But he couldn't overpower the guard who held his chain. Jr waved for the guard to take Spyro back to his cell, the chefs would need a couple hours to cook lunch.
At lunch, Boswer Jr had a new idea. He held out a burger for Spyro, and when the dragon tried to bite it Jr pulled it back out of reach. Grease dripped onto the floor. "Nuh-uh. Not until you say 'I'm hungry'."
Spyro stared at the juicy burger for a minute or two before he said. "I'm hungry?"
Jr let him eat the burger and grabbed a new one. "Now say 'I need more food'."
Spyro tilted his head, he most definitely did not need any more food.
"Go on now, it won't hurt to say it." Jr said.
Spyro grudgingly muttered "I need more food." and ate another burger. He was getting full at this point, but there was still so many left to finish. He wished Jr wouldn't play this game and just get lunch over with.
Jr had Spyro repeat the phrases, alternating them with each burger. When Spyro was too full to eat anymore, Jr actually let him go back to his cell to sleep it off. "You can just finish them at dinner." Jr said.
Dinnertime, and Jr was playing that game again. Spyro repeated the phrases when he was asked just to get it over with quicker. 'I'm hungry', 'I need more food'. Spyro hated repeating those words, but he had no choice but to comply with his captor's demands. He was so full afterwards he was barely able to walk to his cell.
***
Every meal was basically the same. Spyro could swear that his meals were getting bigger, but he was somehow able to finish them. That wasn't the only thing getting bigger though; Spyro was gaining weight at a steady pace. His belly bulged outwards further with every meal he ate. His belly hung down and bounced off his legs which had thickened up. Spyro's is butt grew round, as did his face. He was getting too fat for his own good, it was hard for Spyro to move around without feeling the weight on his back pushing him down. Eventually his neck got too fat for the shackle he was wearing. Spyro started scratching at it with a chubby talon during a meal, that was when Jr replaced it with a sparkly golden collar.
The new collar was humiliating, now he really looked like the bratty prince's pet. He hated the feeling of his entire body becoming so squishy and wobbling from every little movement. And the walk, or waddle, between his cell and the dining hall was becoming more and more of a chore. By the time he reached his meals, Spyro was so hungry. He reasoned with himself that he needed to conserve his strength, and restore it whenever he felt tired. He needed to be ready for whenever Bowser Jr dropped his guard. And eating was the only way to recover from these long walks.
It was the day after he got his new collar. Spyro plopped his butt down in the dining hall, panting but ready for another meal. Now Spyro wasn't the only one who had gotten fat. Bowser Jr had been pigging out ever since he settled on the island. 
The koopa had ballooned, his belly resembled a saggy beach ball with two moobs resting comfortably on top. His face was framed by two big cheeks which wobbled when he spoke. Jr's arms and legs were as thick as Spyro's neck, capped by fat fingers and pudgy feet. His thighs were huge and melded with an equally large ass. Spyro could feel the ground vibrate under Jr's heavy footsteps, and was impressed that Jr could still walk.
When Jr sat down next to Spyro, he did so with a great thud. "Who's a good boy!" Jr reached over and rubbed Spyro's back and the dragon growled. "Hey, that's no way to treat your master," Jr picked up a plate of pancakes and sausages. "You can eat once you say 'I'm hungry, master.'"
"No way am I calling you that," Spyro closed his eyes and looked away.
Jr waved a sausage in front of Spyro's nose. "I know you want it." he said in a sing-songy voice.
Spyro started drooling. It was one extra word, but it was a significant word. His empty belly growled wanting to be fed. Spyro closed his eyes tighter, his pride not letting him give in to Jr's demands.
"Spyro," Jr said, "you can't deny your hunger."
Spyro sighed, but reluctantly mumbled "I'm hungry mas..." He trailed off into silence.
"What was that, boy?" Jr said.
Spyro opened his eyes and swallowed his drool. "I'm hungry, master," he forced that out angrily. He was just glad that Jr gave him the plate as he chowed down.
Jr patted his pet again as he ate, and then a butler koopa handed the prince the next plate of breakfast. "You know what to say next."
Spyro gritted his teeth as he spoke. "I need more food. Master." He ate the next plateful.
"Let's change things up a little. Say 'I'm a good pet'." Jr said.
"I'm a good p-pet." Spyro's belly was still grumbling for more food, so he had to comply. Jr put down another plate of breakfast food.
"Say 'I love my master'."
Spyro bit back the bile in his throat and spat out the phrase "I love my master." And got another plate to dig into. Spyro's body had fully adjusted to this heavy diet, and he didn't even think to question how much he was eating anymore. Jr kept him repeating these four phrases for the next 4 hours until Spyro was beyond stuffed. His belly ached, but it was only painful when he moving. Back in his cell, he flopped onto his side and listened to his belly grumble as it digested until he fell asleep.
Spyro had been saying those affirmations so often that he had begun to say them in his dreams. In the dream, Jr told him "You're such a good pet", and Spyro and he repeated one of those dumb phrases. The dreams always left Spyro feeling unsettled when he woke.
Lunchtime came along and Spyro woke up with a groan. The koopa guard had to roll Spyro back on his feet. His belly was already grumbling for food, and he found himself drooling as he thought about lunch. He was disgusted by himself because he was looking forward to eating more food. He just wished that Bowser Jr would stop messing with him so much and just let Sparx go! 
Bowser Jr was in a great mood when they met up again for lunch. "Oh you lucky draggy." Jr cooed as he held out a plate of food to Spyro. "I'm gonna spoil you so much you won't ever have to worry about food again. You just gotta say the magic words."
Spyro's heart sank at having to say those stupid words one more time. "I'm hungry, master," he whispered. Today lunch was fried chicken and fish sandwiches. Jr had a butler hand Spyro his food so that he could eat his own lunch at the same time.
"Good boy." Jr said as he watched Spyro finish his lunch. Jr held up his arms so that a servant could help him stand up, and Spyro was sent back to his cell once more.
Dinner time rolled around, and once again Spyro was summoned, but this time to the throne room. Apparently Jr was too lazy to get up from his throne. Dinner was more of the same, with Spyro hesitantly saying his affirmations and eating for hours. Jr made sure to praise Spyro as he admired how big his pet had gotten.
***
Spyro continued to get so much fatter as the months went on. His belly dragged along the ground and his butt cheeks had become swollen with so much fat that his fat hind legs could barely lift it all. His neck had thickened with the extra chins the dragon boy was sporting. In fact, it was hard to tell that he had a neck at all, and Jr had to replace his collar twice.
Spyro grunted and panted with the effort it took to waddle through the halls, the lard on top of his back weighed on his spine. He had to pause for breath before ascending the stairs outside the dungeon. The stair steps had been replaced by a ramp, and the koopa guard had to push against the dragon's broad rump to get him to the top. Spyro needed another breather once at the top.
All of this physical labor made Spyro so much hungrier, and he reassured himself that he'd be rewarded with something tasty once he finished the trek. How long had he been here? Spyro had lost all track of time
When he finally got outside, Jr was sitting on a palanquin carried by several koopas. Spyro had been summoned by Bowser Jr to join him on a tour of the farming town outside the fortress. Jr had grown immense from all the food he took from the farmers, and felt like showing off.
Spyro, still panting, looked around and saw Sparx, looking a little bloated himself, sitting on top of the palanquin. "Hey buddy!" Spyro called out to Sparx, who struggled to take flight for a second before flying over to land on the crest on Spyro's head. Sparx had been freed today, and Spyro was glad to see him doing so well. "They been feeding you well?" Spyro asked.
Sparx buzzed happily in response.
Spyro's stomach rumbled and he looked up at Jr. "Master, I'm hungry."
"Of course you are," Jr waved a fat hand and a koopa gave Spyro a chicken leg. "Now come along." Spyro hopped onto his own smaller palanquin and they were off.
They traveled to a part of the island where a whole village of rabbit farmers lived. A few people were busy working on their vegetable gardens while some others were tending to livestock. As soon as Spyro and Jr arrived, people crowded around them to see their evil overlord and his 'pet'. They were shocked to find out that Jr's pet was none other than their hero, Spyro. The townsfolk couldn't believe that this once-hero could fall to such low depths.
"We never expected this from him," said one old farmer as he gazed upon the obese dragon welp. Spyro was blushing with embarrassment. But after Jr's koopas put a bucket of fried chicken in front of him, Spyro dug into it and hid his red face in the bucket.
"I used to look up to him," said another man as he wiped tears of sadness away from his eyes. "But seeing him like this..."
"Cheer up you dumb farmers," Jr said. "As you can see, Spyro is enjoying his life as my big fat pet. And he has you all to thank for this. All the food you've been producing has gone straight to his waistline, and mine too," Jr giggled and slapped his belly. "I'm so thankful for your generosity."
The rabbit farmers stared at each other uncomprehendingly for a moment, and then slowly nodded as if in agreement. "Y-you're welcome," said one of the farmers.
"Now where are my offerings?" Jr pointed a fat finger at the crowd, "I want some fresh vegetables for my fat pet here."
The farmers hurriedly set aside the vegetables they had already harvested and brought them to Spyro. After that, the koopa guards escorted Spyro and Jr around the village for hours as they ate their fill and received a variety of different types of meat and veggies. Spyro was stuffed full of everything the town had to offer. Spyro ate and ate, focusing on eating and soon his embarrassment was replaced by the comfort of a full belly.
The townsfolk, for fear of Jr's wrath, made sure to praise Spyro.
"He's really a nice dragon," said one farmer.
"It must take a lot of effort to get that fat," said another.
"I think he's cute," said a little girl.
Finally the tour was over, and Spyro and Jr went back to the fortress. Once they returned inside, the koopas helped Jr down onto his throne and Spyro onto the floor. Sparx landed on Spyro's head once more. 
Jr rubbed his belly. "Man I'm so stuffed right now," he laughed. "I bet you two are pretty happy right now."
Spyro was stuffed and it felt satisfying, but at this rate it wouldn't be long until his belly was so big he couldn't move anymore. Spyro sighed as he realized how trapped he truly was. Jr might have released Sparx today, but Sparx didn't seem very enthusiastic about leaving anymore. And strangely neither did Spyro. Now that his little buddy was safe and happy, Spyro just felt relieved. He felt like he no longer had to do anything else for the sake of anyone else. 
"Now that you two are free, what will you do?" Jr said.
"I guess we'll stay here. Right Sparx?," Spyro said.
Sparx buzzed a happy "uh-huh." his belly full of butterflies.
"If you'll keep us, master." There was no more hesitation in the fat dragon's voice. His only goal in life now was to eat more and get fat.
Jr was ecstatic, the dragon and dragonfly had grown on him during their time there. "Oh yeah! Yeah I wanna keep my pets! Don't you worry about a thing. You just stay with me forever and we'll have a blast together!"
It was clear that Jr's reign wasn't going to end anytime soon. After that, Spyro's days were spent eating, sleeping, and being praised by Jr and the town rabbits. Spyro enjoyed being the center of attention and the growing adoration of the town.
