Mordecai sat at the small rounded table, located in the small cramped kitchen.. He was at Rigby's new house, Rigby had recently bought it and was excited to be able to host Thanksgiving there, but he had a little more planned for the evening than you'd expect... Rigby had told Mordecai that he had invited a number of friends and family to come over for the dinner, but they 'unfortunately all cancelled last minute' – What a coincidence. Mordecai had been sitting silently at the table for about half an hour, with Rigby working busily behind him at his cramped worktop. “So, is it nearly done Rig?” Mordecai asked, beginning to grow impatient but didn't want to show it to rush Rigby. “er, almost~” Rigby replied – But it was far from done, as he didn't even have a turkey to begin with. His plan was going perfectly.

“Damn, I think I've overdone it too much-” Rigby told Mordecai, standing in front of the oven to hide the fact that nothing was in there to begin with, “But I have a pre-made back up turkey down in the basement.” “You have a basement?” Mordecai asked, curiously, “Sweet!”
“I'll just go get it now,” Rigby told Mordecai as he left the room, “Just stay there, I won't be long.” Rigby lifted up the hatch in his small hallway, revealing a set of wooden stairs. He slowly walked down, pulling on a small string to bring light into the room. “Hey, Morde!” Mordecai heard Rigby shout, “It's kinda heavy, could you help me?” He sighed, standing up from his chair, placing his napkin down on it, “I'm coming!” He said, walking into the hallway. He slowly began to climb down the stairs, but he knew something was up as when he took a quick glance into the room all he saw was chains and odd machines. He didn't get chance to look for very long, as Rigby pounced atop of him, putting a blindfold over his eyes. “What the?” he exclaimed, before he swiftly passed out.

Mordecai slowly began to open his eyes. He saw Rigby stood in front of him, he was wearing an apron and holding a bowl of something. As Mordecai adjusted to his surroundings, he noticed that his arms and legs had been restrained. He was pinned against a wood board, with cuffs and chains around his arms and legs. “R-Rigby?! What the hell is going on?!” He screamed at his friend.
“Look, Mordecai, I have all this stuffing, and I think you need to be... filled.” Rigby took a large wooden spoon out of his apron pocket, and took a large scoop of the substance from the bowl. It was clear to Mordecai that substance was stuffing, as it began to move closer towards him. “Open wide, Morde...” Rigby said as he moved the spoon towards his re-strained friend. “What? No!” Mordecai refused, closing his mouth shut. “Look, Morde, we either do this the easy way, or the hard way – Now, open your mouth.” Mordecai had no other choice but to follow the orders. He un-willing opened his mouth, feeling the tough wooden spoon against his tongue. The stuffing fell into his mouth, and he swallowed it toughly. “That's it...” Rigby said – he placed his hand upon Mordecai's belly, “Don't worry, you'll be getting bigger in no time~” He teased.

Mordecai opened his mouth once more, talking another large scoop of stuffing and swallowing it. He stomach grumbled as he noticed it expand slightly. “I think your belly wants more, “ Rigby said as he scooped more stuffing into Mordecai's mouth. Mordecai blushed as he swallowed once more, feeling the smooth stuffing rush into him, making his belly bulge. Rigby noticed Mordecai's blush, “You're enjoying this, aren't you?” He asked, “N-No...” Mordecai replied swiftly, “Oh really? Well, I guess I'll have to keep filling you until you enjoy it-” Rigby took another scoop, pouring it into Mordecai's mouth. He began to rub Mordecai's belly as it bumped up a little more. Mordecai blushed harder as he felt the firm hand rub slowly over his soft, growing stomach. Rigby took the wooden spoon and threw it a side, and took the bowl with both of his hands. He took it and placed it against Mordecai's face. “Go on, eat it,” He teased as he began to pour the whole bowl into Mordecai's mouth. Mordecai gagged as he felt the thick mixture push down his throat into him stomach. He's belly continued to grow at a faster rate, it became rounder and pudgier. He kept swallowing the stuffing, blushing as he felt his mid-section bulging further. Once he finally finished the bowl, Rigby put the empty bowl on a table beside him. “Wow, you sure have grown~” He stated, almost shocked as to how well Mordecai had taken it. He took one of his claws and lightly ran it down the side of the stomach. “Your big, but not big enough...” Rigby told his plump 'victim' as he went over to another table near the stairs. On it was another bowl of stuffing, but it was thicker than the last. “Think you could take more?” He asked as he picked up the bowl and returned to the tied up pudgy blue jay. “I-I don't know...” Mordecai stuttered nervously as his stomach began to grumble and groan. “Well, it doesn't matter, because I'm gonna keep filling you anyway~”

Rigby took one hand, and used it to hold Mordecai's head back, and he held the bowl above his stuffed buddy. “Say 'Ahhh'” he told him, and reluctantly Mordecai began to open his mouth. As soon as Rigby saw the bird's tongue, he began to pour the stuffing in. Mordecai gagged once more as the stuffing filled his mouth. It felt thicker than the other batch, and was harder for him to swallow, but the constant stream of stuffing kept flowing, pushing it down his throat. Mordecai began to feel a much more intense full feeling as his stomach bulged like before, but the thickness of the substance was filling his stomach at much more intense rate. His stomach reddened lightly as it pushed out further than before. Mordecai could see the pleasure in Rigby's eyes as he watched his friend's stomach fill, and while it did hurt, Mordecai himself was actually enjoying it a little. His belly groaned and creaked lightly as it grew rounder and rounder. It wasn't just sticking out upwards, but it was also pushing out sideways. He was getting bigger than any woman could get while pregnant. Mordecai squeezed his eyes closed as the pressure pushed harder and harder, getting more and more intense. He'd only taken in about half of the bowl, but he felt as if he was ripe to burst. He began to wriggle his arms and legs, trying to loosen the chains, but it was no use. “Oh, trying to escape are we?” Rigby teased as he stopped the pouring for a moment, “Because you're not going too – You know what, I think I'm going to give you even more for that.”

Rigby poured the remaining contense of the bowl into a large tank hanging from the ceiling. He reached over to the cupboard beside him, pulling out yet another bowl of stuffing, but this bowl was even larger. “I have a lot of stuffing prepared for this~” Rigby explained, pouring this bowl into the tank as well. Dangling from the tank was a thick, rubbery hose. He took the hose with one hand, and forcefully pushed into the blue jay's mouth. He turned a small knob on the tank, causing it to open up it's contense to rush down the hose. Mordecai's eyes bulged as he felt the familiar taste of stuffing on his tongue. It slipped down into him even quicker than before, causing his rounded tummy to continue pressing outwards. Rigby placed his head upon Mordecai's growing belly, placing his arms around him. He felt Mordecai's huge, taut belly pressing firmly against his face. He began to rub Mordecai's belly as he continued to grow. The reddening continued as the belly pushed and pushed, grew and grew, bulged and bulged. Mordecai could no long see his bottom half of his body due to his hugely plump and ripe belly blocked it. He could barely see Rigby at all. Rigby climbed onto his friend's ever growing belly, and sat upon it, staring at Mordecai directly. “Keeping growing.. That's it...” he said as he felt the tight skin stretch underneath him and upon his butt.

“MmMMmM!” groaned Mordecai as the last drop of stuffing fell from the tank into his mouth. After one last gulp he panted briskly, it was over. He'd swallowed it all. Rigby sat comfortably upon his throne – Mordecai's huge plump belly. “Well, Mordecai, it seems we're done here~” He said as he hoped down from the rounded stomach. Mordecai moaned as the pressure from Rigby's body was removed, and his belly pushed at even further due to it. Rigby began to undo the cuffs on Mordecai's arms and legs – He knew that Mordecai wouldn't be able to escape due his newly huge tummy. Rigby lifted Mordecai slowly off of the wooden board, and placed him into a small metal cage, shutting the door behind him. Mordecai sat nervously, holding his huge belly with his hands for the first time. He rubbed it softly as it moaned and groaned, he couldn't come close as to reaching around it all. “Don't worry,” Rigby told his bloated pet, “We'll cook you in the morning~” Rigby winked at Mordecai, as he walked towards the stairs. He pulled the cord to turn the lights off, as he climbed the stairs, leaving Mordecai's fate unknown.
