The smell coming from inside the cottage was so tantalizing that Rainbow Dash just stood in front of the door, immobilized and drooling profusely. Pinkie Pie tried poking her plushy side to wake her up, but it was no use.

"I-uh....guess that means I should knock?" And so, Pinkie knocked on the front door. "Fluttershy! It's me and Rainbow Dash! We want to show you something!"

Soon, Pinkie Pie heard rushed hooves shuffling for the door. It swung open, revealing a rather stressed looking Fluttershy. Her hair was ragged and her eyes tired.

"Oh...Hello, guys...." Then, she gaped when she looked at Rainbow Dash, who was still staring into space with drool dripping off her tongue. It looked like she gained more than 60 pounds! And, last time Fluttershy saw her, was two days ago. She was normal then. How could she get so fat in two days?

"U-um....N-not to be rude, but...R-Rainbow, you're looking a little..."

"FAT? Yeppiroonie! This is what we came here to talk about! But, first, what happened to you, Fluttershy?"

"Oh, it's been awful. I've been watching the Cutie Mark Crusaders since yesterday. And, they behaved so well yesterday that I thought that it would be a good idea to treat them with chocolate from Bon Bon's candy shop today. B-but I was wrong. I-I couldn't resist those darling kids, and I let them have too much. They've been bouncing off the walls, and Bon Bon had Lyra help me get them in here. But, Lyra didn't help much after that. She just snacked on most of my pantry and fell asleep in the kitchen. *sniff* T-the girls had gotten so out of hand that I p-panicked and felt that I had no other choice but to use my *sob* emergency tranquilizers on theheeheem."

Fluttershy broke down. "I DIDN'T WANT TO!!! *SOB* WHEN RARITY AND APPLEJACK FIND OUT, I'M GONNA BE IN SOOO MUCH TROUBLE!!!" She proceeded to cry hysterically. Rainbow Dash was taken out of her trance when she realized that Fluttershy was crying. Despite the fact that she was planning to eat Fluttershy, Rainbow Dash still had a soft spot for her. She was her childhood friend, after all.

Rainbow Dash nuzzled Fluttershy's wet cheek. "Hey, hey...relax, Fluttershy...*GROOOWL* Oh shut up for a second! N-not you, Fluttershy! My stupid stomach!"

"*sniff* T-thanks Rainbow Dash...I guess I overreacted a little...Oh, I wish I could just get rid of those kids...U-UHM-I-MEAN...*sigh*"

Then, Pinkie Pie got an idea. "Rainbow Dash can get rid of them!"

Rainbow Dash gave Pinkie Pie a look that was both confrontational and nervous at the same time. "P-PINKIE!!! DON'T G-GIVE ME IDEAS, NOW!!" *GRROOOOOWLL* Rainbow Dash's cheeks went rosy as she smiled awkwardly at Fluttershy. She now figured out why her cottage smelled so spectacular. There are five ponies here at the same time. Most notably, Lyra was here. Lately, Lyra has been packing on the pounds. Rarity gossiped that Bon Bon has been fattening up her marefriend because they realized that they liked a feeder plus feedee relationship. Rainbow began to sweat as her eyes dilated and saliva built up on corners of her mouth.

Fluttershy calmed down and looked at them both curiously. "What's wrong with Rainbow Dash?"

Pinkie Pie perked up. "That's what we came here to share with you!" She sucked in a bunch of air and proceeded to utter everything that happened from last night up until now in a flurry of verbal nonsense.

Rainbow Dash now looked angry. "UHG!! DARN IT, PINKIE PIE!!! NOW I HAVE TO-huh?" Rainbow Dash was a bit taken aback by Fluttershy's reaction to Pinkie's exposition. Her face was red and sweaty. And her wings were erect and throbbing.

"R-R-RAINBOW?! Y-y-you c-consumed the Sable Satiator Gem?!?!.....N-n-no wonder you got so...so...big...s-so fast!"

"Oh, riiiight. That was the name of this thing......WAIT......WHAAAAAT?!?!? HOW THE HAY DO YOU KNOW ABOUT THE BLACK GEM?!?"

Fluttershy looked down at the ground and shut her eyes tight. Her entire face was crimson.

Rainbow looked at Fluttershy with concerned eyes. "....You.....have a vore fetish too?......"

"YYYYEEEEESSSSS!!!!!!", she screamed up to the heavens.

Pinkie Pie and Rainbow Dash were shocked. They never suspected that Fluttershy of all ponies would have such a dark fetish. And, despite being childhood friends, Rainbow Dash and Fluttershy never dared to reveal these fantasies to each other. They never expected to have this in common.

Fluttershy had to compose herself once again. She looked at Rainbow Dash with a black glint in her eye.

".....Please come inside...."

______________________________________________________________________

Rainbow Dash, Pinkie Pie, and Fluttershy were sitting in the living room. Fluttershy thoroughly explained her desire to experience being swallowed by another pony. She learned of the existence of the Sable Satiator Gem before she moved to Ponyville. Ever since then, she occasionally had fantasies involving various ponies that she knew being under the gem's influence.

However, over the years, she learned quite a bit about what kind of power it had. As much as she would love to fulfill her sick desire, she didn't want to ever tamper with that power. There was a reason why these black gems were kept locked away from everypony.

"So, Rainbow, I'm guessing that you have noticed that you haven't been yourself since you've swallowed the gem?"

Rainbow Dash was squirming in her seat while her stomach churned and flickered violently. She was sweating and drooling; evidently restraining herself from cutting her friends off short.

Pinkie Pie spoke for her. "Yeah. She can't stop eating. She has a weird, glowy tummy. She hardly cares about anypony's well-being anymore. She spaces out and mumbles creepy stuff to herself. And......sometimes.....I feel like I'm being manipulated by the gem too....It's very creepy...But I'm having tons of fun!!!"

Fluttershy seemed concerned, but in a very strange and slightly sarcastic way.

"Poor thing. The gem is essentially a parasite in the form of pure, dark magic. Nopony knows exactly how or why, but the dark magic that the gem holds is a being itself that uses ponies' life force to grow stronger. A very long time ago, these gems were used by the dragon tribes that tried to wipe out the ponies from Equestria. Whether they consumed the gems themselves to harness powerful magic or sabotaged ponies' diets to whittle their numbers from the inside, the gems were the dragons' secret weapon. However, even the dragons began to fear them, for they couldn't control the dark magic once it got too powerful. And, eventually this - along with the Princesses - caused the dragons to give up on conquering the ponies. Nearly all traces of the Sable Satiator Gem had been disposed of or locked away."

"WOOOOOW. That's a neat story, Fluttershy. But-um....can we just feed Rainbow Dash now? I know you want to. And, she's getting a little impatient."

Fluttershy blushed. Her wings were erect again. "W-well, I-I never wanted to use the gem to fulfill my desire because ponies pretty much become monsters when they are possessed by it. B-but.....since it's already too late for Rainbow....." She smiled creepily as she gazed at the pegasus intently. She then whispered to Pinkie Pie, instructing her on a roleplay that she had come up with. Pinkie Pie bounced up and down with glee and readied herself.

She began to talk to Dash in a lewd, condescending tone. "So, fatty, you look pretty hungry for some of this. Don't you?" She put her forehoof in front of Rainbow Dash's muzzle. Fluttershy pulled it away the second Rainbow snapped at it. "Uh-uh-uh. You're looking too thin for my taste. I've got some yummy ponies in the kitchen that I want you to try first. Then, I'm all yours."

Rainbow Dash got really excited. "Y-Y-YOU BET!!!" She got up to rush into the kitchen, but both Fluttershy and Pinkie Pie stopped her in her tracks.

Pinkie Pie started scolding Rainbow Dash as if she were the Cake twins. "Nuh-uh, missy. If you don't behave yourself, I won't let you have all 5 ponies."

Rainbow Dash was so hungry and out of it at this point that she started actually acting like a little kid. Which, wasn't really that abnormal for her when she didn't get what she wanted.

She stomped her hooves and whined, "But I want them in my bellyyyyy!!"

Fluttershy smiled deviously. "Oh, I'll stuff you up good, fatty. Don't worry. Just do what I say, and you will be a fatter and happier Rainbow Dash. Now, wait a moment while I prepare your meal."

Fluttershy trotted into her kitchen and got some large plates to put on the table. All four of her guests were still unconscious, so she put each Cutie Mark Crusader on a separate plate and covered them all. She grabbed one of her moderately sized, wooden chairs for Rainbow to sit in. Lyra was in another chair, and was far too big and heavy to lift up onto the table on her own. She looked just about as big if not, bigger than Rainbow Dash was now. So, she just let her sit there for now. Fluttershy would have to improvise with her. Not wanting to make Rainbow Dash wait any longer - and wanting to get swallowed up soon, herself - Fluttershy called out to Pinkie. "Okay, Pinkie Pie! Bring her to her seat!"

Pinkie Pie guided Rainbow Dash to the wooden chair. When Dash sat in it, it creaked slightly from her extra girth. Her butt nearly filled up the chair completely. Her belly was slightly covering her lap as it bunched up and pushed forward.

Rainbow Dash was anxious to start eating. She pounded on the table. "Give me the ponies!! NOW!!" The black glow on her belly flickered in agreement.

Pinkie Pie scolded her again. "With that attitude, you'll be getting none, miss Rainbow Dash!!" Pinkie covered her mouth as she contained her laughter.

Rainbow Dash whimpered as small tears formed at the corners of her eyes. "Y-yes....ma'am..."

Pinkie nearly squeed. That was so adorable. Fluttershy came over with a white bib and secured it around Rainbow's chubby neck.

"Aaaaw..." Fluttershy caressed and rubbed Dash's belly. "Don't cry, fatty. It's time for you to gorge yourself like the fat pig you are. I'll even help you." Fluttershy hovered onto the table and pushed one of the covered plates towards Rainbow Dash. Rainbow Dash bounced in her seat as her eyes glistened and she licked her lips.

Fluttershy took the lid off with her teeth. Rainbow's hungry expression intensified as she gazed upon her little fangirl, Scootaloo. She smelled like a cupcake filled with peanut butter and jelly. An odd concoction, but delicious and fattening all the same.

Fluttershy cradled Scootaloo in her forelegs and hovered above Dash's face. "Say AAAh!"

"AAAH!!" Rainbow's jaw opened wide with her tongue hanging out as Fluttershy gently pushed Scootaloo into it, head first. Dash's sky blue lips wrapped around the fillies head. She closed her eyes and licked all around it. "Mmmhmmm...." She tasted just like what Rainbow Dash had smelled. Fluttershy shoved the rest of Scootaloo into Rainbow's mouth. She slurped up the tail and swallowed the flightless, pegasus filly whole. The bulge in her throat dropped into her plushy paunch which jutted slightly further towards the table. She patted her belly as Pinkie Pie glomped her love handles from behind. Rainbow Dash sighed with pleasure. She was in heaven.

A small jolt of terror struck Fluttershy at this moment. She had never witnessed something so bizarre and unnatural. However, this only further stimulated her. For once, she was getting a rush from being scared. It was as if her natural instincts had been broken.

The voice spoke to Rainbow Dash again. *yESsSSS....YOu pOnIeS' DEsires MAKe YouR WiLLS wEak!!!*

*You're totally right, creepy dude! I'm not complaining. I get more ponies that way!*

Fluttershy proceeded to push the next Crusader towards her pudgy grave. Applebloom was revealed. Fluttershy was somewhat hastier with her and shoved her in between Rainbow Dash's chubby cheeks.

The taste of sweet, candied apple graced the rainbow maned pegasus's tongue. It didn't last too long though, as she gobbled up her friendly rival's sister in seconds. Rainbow spread her legs to accommodate her ballooning gut - which was now merely an inch away from touching the table. As Pinkie rubbed her belly, Rainbow's chair creaked a little louder. The glutton's ass filled her seat a bit more.

*BUURP* "More..."

Pinkie patted her mistresses paunch. "Good girl. You have a healthy appetite."

When Sweetie Belle was put in front of her, she just grabbed her with both hooves and stuffed her fat face with the marshmallow flavored filly. Rarity wouldn't have to deal with her anymore. Dash's stomach was now pushing against the table. The bib was straining to stay locked around her widening neck. The chair's legs bent slightly as it creaked in further protest. She kind of liked the feeling of outgrowing her surroundings. She moaned and belched happily. But, then she saw her on the other chair. Lyra was a nice, fat mare that Rainbow wanted so badly.

Fluttershy was so turned on that her crotch was wet. "Well, well, well, fatty. You still hungry? Let's see how you like the main course! Help me, Pinkie!" Pinkie Pie and Fluttershy used their combined strength to get Lyra onto the table, splayed out on her belly.

She didn't even stir in her sleep. She must have eaten herself into a food coma.

Both Pinkie and Fluttershy pushed against Lyra's big flanks. She slid towards Rainbow Dash who had opened her mouth wider than ever, which was a little difficult considering how much her belly got in the way. When Lyra was close enough, Rainbow pulled her in. The bib snapped right off when Lyra's head entered her throat.

Fluttershy and Pinkie Pie continued to push as Rainbow Dash pulled, gulping down the large, mint flavored, filly fooler. The moans of ecstasy intensified as the wide load made its way into her gut. It took a few minutes of pushing and swallowing, but Lyra's luscious flanks were disappearing into Rainbow's monstrous maw. Her cheeks were comically large as Lyra's waist was stretching them out. Soon, all that was left was Lyra's legs and tail. Rainbow savored Lyra's buns for a few more seconds until....

*GUUUUUULP* The colorful pegasus's stomach bloated enormously as the fat mare joined the three fillies. The chair snapped loudly as Rainbow's huge body crashed to the floor. She was splayed on her back as her belly wobbled slightly from impact.

*BOOOOOOOAAAAAAAAUUUUUUUUUUUUURRRRRRRRRRP*

The booming belch made the entire cottage shake slightly. Pinkie Pie jumped onto the huge, taut dome and caressed it with all four of her legs. Fluttershy felt a surge of adrenaline. This was it. This was her chance to finally experience her most erotic dreams in reality. She looked over at Pinkie Pie with a face of parting sorrow.

*YEss....YeEeESSSSsss!!!*

She gently spoke to Pinkie, “...Pinkie Pie...Rainbow Dash....I don’t think I can wait any longer. Becoming a part of another pony is the way I want to end my life. You two have been such wonderful friends. Especially you, Rainbow Dash.” She nuzzle Rainbow’s fat cheek as Dash laid on the floor breathing heavily, massaging her mass, and sweating. Rainbow blushed and burped again.

“T-thanks-URFH-Fluttershy.”

Fluttershy continued, “I know that Ponyville will probably be doomed if you keep stuffing your face with the residents. But, right now, I don’t care about that at all. Is that cruel? Am I being malevolently selfish?”

Pinkie Pie commented, “I wondered the same thing about myself when I decided to serve Rainbow Dash’s new body. But...something just feels right about this. I think we’ve finally all gone loco. And, it’s fun!!”

“Well, I guess so. Huh?” Fluttershy positioned her body on Rainbow Dash’s barrel. She had her snout up against Rainbow’s. Her wings flared and her vaginal secretions were seeping onto Rainbow Dash. “You ready for dessert, fatty?”

“*PANT* Of *PANT* Course!” Dash licked all around Fluttershy’s snout. Fluttershy blushed. She tasted like a banana cream cake with strawberry icing. “Mmmhmm. You’re way too *uuuuurrrrp* delicious for me to *huff* let you go uneaten. Now...GET IN MY BELLY!!”

Rainbow Dash’s tongue wrapped around the back of Fluttershy’s head. She was pulled in past the lips. The feeling of being ingested was just as arousing as Fluttershy had imagined. She pushed herself in as Rainbow swallowed. As she made her way into the throat, it didn’t take long for Fluttershy to orgasm. At that point, most of her backside was in the mouth. Rainbow Dash moaned intensely as she savored the sexual fluids along with the already amazing flavor. After that, Rainbow Dash greedily scarfed down the rest of Fluttershy. With a hard swallow, Rainbow Dash was the most stuffed that she had ever been in her whole life. Fluttershy was cramped inside the darkness with soft, unconscious bodies of her guests. She could hear the labored breathing and churning. The pounding heart beat. She even felt the rumbling of Dash’s gastral outbursts.

“Thank you....Rainbow Dash...” She let the darkness take over and soon was still.

“*BRRAAAAUUURRP*....*PANT*....Oooooh....*UUUURRRAAAAAP*....What a meal...”

Rainbow Dash fell asleep as Pinkie Pie continued to massage and caress her mistress’s bloated, drum tight gut.

“Good girl, Dashie. You ate all 5 ponies in one sitting! Now you’ll grow up to be nice and big and round!”

*tHe PoWEr......YESSS......WE ARE MOVING ALONG QUITE NICELY....*
