Rainbow Dash awoke to find herself lying on a bed of cushions. She groaned and rolled over onto her side. As she opened her eyes, she noticed that she was surrounded by beautiful pastel-colored pillows. She groaned and rolled over onto her side. The room was dark and smelled strongly of sweets. Her stomach gurgled loudly. She quickly sat up and took a look around the room. It was filled with many different kinds of dessert dishes and trays, each one piled high with sweet treats. Pink and yellow cakes, brownies, and cookies covered every surface. A massive bowl of ice cream sat in the center of the room; its creamy contents were frozen solid. Rainbow stared at the sight in disbelief, but her stomach rumbled again and she knew she needed to eat something. With great effort, she pushed herself to her hooves and hobbled over to the nearest dish.

A pink cake lay there, adorned with a large glazed cherry. Rainbow picked it up and took a big bite out of the frosting-covered top. The cake tasted so good! Rainbow devoured the rest of the cake quickly, then started looking for more to eat. The next thing she saw looked promising — a plate of cupcakes. They were chocolate on the outside, vanilla on the inside, topped with bright blue sprinkles. Before Rainbow realized what she was doing, she'd stuffed half the tray into her mouth. After chewing everything down to a pulp, she stumbled to another table full of desserts and began to gorge herself once more. If the other ponies were staring at Rainbow as if they couldn't believe how terrible a gluttonous mare she really was. One after the next, Rainbow Dash devours dozens upon hundreds of delectable confections until her entire muzzle was nothing but crumbs. Finally, Rainbow noticed that something was wrong with her. After all, she had never been such a glutton! But right now, eating was so enjoyable. All of those tasty sweet foods felt wonderful going into her maw. Who cared whether she became obese? No one else seemed to mind. Just like before, she just ate and gorged herself on sweets. Soon enough, Rainbow found her belly swollen and aching. At this point, she wasn't sure why she still wanted to keep overeating. Suddenly, she heard footsteps approaching. Her heart skipped a beat as she recognized the voice of Twilight Sparkle behind her.

Just thinking about Twilight made Rainbow blush furiously. The princess would surely scold her for gorging herself quite this much! Yet…as the mare approached closer and nearer to where Rainbow stood, she did not seem angry at all. Instead, Twilight giggled excitedly as she walked toward Rainbow's bloated frame. "Good morning!" Twilight said brightly. "You disappointed me Dashy. I expected you to eat more in your first gluttony session. We will have to fix this next time. How do you expect to gain weight if we aren't feeding you properly?"

"What the hay, Twilight! I will never gain weight! I am an athlete! Even my body image is based on my strength and agility...not having a gut," Rainbow snapped angrily. Then suddenly, things got worse yet for poor Rainbow. As she spoke, she let out several belches into thin air before turning redder than ever at the sound of laughter coming from Twilight.

"An athlete, hah! We will fix this soon enough. But right now, we have to take care of your aching tummy. Come along now, Dashy. Let us find somewhere comfortable to sit together..." With that, Rainbow Dash was led away by the mare, who sat her down in front of a mirror. Right before her eyes, she saw that her muzzle and chest were covered with cream and crumbs. Once flat belly bulges stretched painfully across her torso. Slowly, she opened her mouth, letting loose several loud grunts and burps as she tried desperately to relieve the pressure building within her abdomen.

"Look at yourself, Dashy. You are a little novice slob. Look at those doughnuts you ate earlier today! A real athlete wouldn't make a pig of yourself. Gluttons and gluts should stay home and watch television, or maybe just play video games until they lose themselves entirely. That's why we need to turn you into a proper gluttonous snacking machine…" Twilight whispered seductively as her hoof reached over and began rubbing the mare's belly softly.

"This is insane, Twilight!" The soft belly rubbing made Dash burp again. "I mean—we've known each other! Can't we talk about this? My belly is aching!" "That is because your stomach is too small. We will gradually stretch it to an acceptable volume. You will love this! Endless munching and gaining weight are your destiny! Soon your paunch will grow to gargantuan proportions. Soft and warm! Just what every pretty pegasus pony deserves." Suddenly, Twilight leaned forward, planting a kiss on Rainbow Dash's lips. As she felt Twilight's tongue enter her mouth, she found herself unable to protest further. Forcing herself to swallow, she realized what was happening. Not sure whether she wanted to scream or cry, Rainbow took deep breaths and waited for Twilight to finish kissing her. Eventually, the mare pushed back, looking satisfied with her work.

"Your tight swollen belly is so attractive. And your impotent anger makes it even better! At first glance, you seem such a strong and beautiful creature...but inside you are quite helpless indeed." Twilight giggled. "Let me help you relax… Here I go with that wonderful magical massage of mine. Your belly is already feeling bloated after eating all those snacks. Well, it shall remain that way forevermore. When we will finish nothing will satisfy you except more and more food. All your muscles will atrophy and you will develop saggy skin which I will caress lovingly during our massages."

"Noooooo! Stop!" Rainbow's mind was terrified even though her body was melting due to the magical massage of her aching abdomen. "You have to listen to me, please, I…"

"Hush," came Twilight's soothing voice as she stroked her cheek comfortingly. "Just let things happen naturally. Imagine that my hoof is slowly pushing food between those lips of yours, stretching out your insides and filling your guts full of butterfat and sugar. Feel that delightful sensation spreading throughout your whole body? These are calories that transform into fat. Every second is another calorie toward your transformation!"

Slowly, Twilight lowered her head until their noses were touching delicately. Then, using gentle kisses and nibbles along with the mares' ears and neck, she worked her way down to the chest area where Rainbow Dash gasped loudly beneath the treatment.

Slowly moving lower still, Twilight licked and sucked upon Rainbow Dash's sticky fur before finally trailing her moist tongue across her navel causing her to groan audibly. "With this little magical stimulation, your stomach will be empty enough to continue the feast soon. Look at the mirror in front of us. What did you notice?" asked Twilight.

"My bulging tummy..." answered a trembling Rainbow Dash timidly.

"And yes! Of course, that's right. The sight of your rounded tumors makes me giddy with joy. By tomorrow morning everything will swell up nicely, especially once all these delicious sweets soak through your cotton candy flesh and make you plump and juicy beyond belief. From here on out, there is no stopping me from transforming you into a soporifically obese gluttonous princess.

"I got chubby! Oh gosh, look at me, I'm plump and gross! Why do I allow this?! How come I am allowing this?!"

"Because eating is pleasurable," answered Twilight smugly. "Think about all the hours spent exercising and working hard at everything you ever tried. Think about how many times you failed. Yet despite all odds, you never gave up trying. Is it pleasurable?"

"No... But..."

"That's exactly why you should surrender yourself entirely to pleasure instead. Remember, food is a reward for your effort. If your belly fills itself with delicious treats over the next few weeks, imagine how satisfied it will feel afterward." As Twilight spoke, her eyes drifted downwards past Rainbow Dash's ample hips and large thighs before coming back to stare straight into her pupils. "Your anger excites me. Good. Your stomach is already empty enough. Look at that table with sweets. Eat any one cake. And if you don't want to continue, you can leave." With that said, Twilight rose gracefully onto her legs and walked away whilst whispering softly to Dash. "Remember, pigy—you want this!"

Twilight left her alone. Just beyond Dash lay rows upon lines of delectably tempting cakes lined neatly alongside colorful candies. Rainbow Dash was surprised to find her hunger growing rapidly after such a short amount of time. Quickly reached for a raspberry truffle cake which looked particularly appealing to her tastes. Taking a small nibble off its edge only made her hungrier however and she took more bites until she had devoured half the dessert whole. Despite it tasting wonderful within her mouth and filling her belly quite well, she felt unsatisfied somehow and continued taking larger chunks that caused crumbs to fall everywhere.

"What am I doing? I have to go. No reason to stay here and gorge me on junk food when I know I need to lose some weight." As she stood up to begin leaving, Rainbow Dash realized that may be a good idea to take one more slice of cake. It wouldn't hurt too badly to indulge just this once since she needed to drop the pounds anyway. She searched among the cakes and found a chocolate cupcake that seemed tasty and decided that would be the last piece she ate today. But it was too tasty and she ate it too quickly. Rainbow didn't feel satisfied. "Just one more bite won't kill me. After all, I will be starving all week."

Once again, Rainbow began searching desperately amongst the desserts looking for something new but couldn't resist having another bite from the same treat. Soon she noticed herself reaching for yet another bite of cake until all ten pieces of the truffled confection rested inside her cheeks.

"I'll eat just one more last sweet. And then I'll be gone!" Rainbow's gaze fell on a giant three-story cake. A huge white frosted cake filled every inch of space on top of a tall pedestal stand surrounded by other desserts. Each layer was decorated differently but each was topped with creamy icing and sprinkled with pink sugar crystals. All of them are equally enticing. After finishing off the remaining bits from what was left of the cake she'd started earlier, Rainbow dove right in. Took a bite of something shiny and smooth. Something covered in sugary cream between layers of sponge cakes and coated in thick buttercream topping. Even as her teeth sank deep inside it, it melted faster than expected leaving Rainbow drenched in sweet to lick it clean. Next came another rich treat that tasted oddly familiar yet different at first glance. Then something squishy, chewy, and fluffy caught her eye instantly due to its striking resemblance to marshmallows. Soon followed by another confectionary delight, a scrumptious fruity pastry that oozed juice through Rainbow's muzzle every time she bit into it. Finally, a fresh batch of doughnuts that smelled so heavenly they nearly drove her mad. She does not realize that she could not finish eating a cake that was larger than herself. But she didn't care at that moment. That feeling of dissonance she couldn't explain faded fast replaced by intense bliss brought forth by every single morsel she consumed. To think that simply indulging in such luxuries that most ponies never get to experience was enough to satisfy her starved appetite completely blew her mind. Dash hadn't eaten anything like this ever before nor dreamed of having access to such delights. She literally dived into the cake and savored every bite. Not wanting to stop at merely eating the delicious things placed before her, Rainbow Dash used both hooves to tear off strips of the lavish delicacies and shove them directly down her throat. Rainbow knew something wasn't quite right because although she enjoyed everything, she ingested she felt slightly ill afterward. She sensed some sort of nausea bubbling up inside her gut and attempted to hold back the urge to vomit, hoping whatever was wrong with her digestive system would pass eventually. Forcing the sensation aside, Dash kept gorging as nothing else mattered in those moments except satisfying her insatiable hunger. Her stomach swelled even more than last time. She looked pregnant with twins. By the end of it all, Dash felt stuffed beyond belief. Exhausted by overeating, she slumped forward heavily with no energy whatsoever. She was lying right in a pile of cream, lazily licking her dirty lips.

"I have to leave before Twilight returns. Or I may never fit my massive bulk out of here! " Rainbow sighed contentedly after letting her tongue roam over her sticky snout once more. With little effort required, she managed somehow to lift herself upright. It took considerable work to push away from the table and rise unsteadily onto wobbly legs until she stood straight and strong atop the floor. Perhaps it might be too late already... In that case, it makes sense to stay and eat some more...she mused to herself as she began working her jaw muscles to loosen all the food stuck within it. Dizziness overtook her momentarily as she tried to walk toward the exit. As she glanced down at her swollen tummy distended uncomfortably between her legs. Every step made her burp. Out of breath and gasping for air, she paused briefly next to a mirror bolted to the wall nearby. What she saw scared her. No longer did she look like a beautiful pegasus mare. Instead, she had ballooned to unimaginable proportions. Her eyes bulged wide with shock and disbelief.

"I see you have succumbed to the temptation of gluttony. Well done," said Twilight with a smile as she approached Rainbow Dash slowly but surely. "You've really grown accustomed to these kinds of treats, haven't you? Don't worry, there is still hope for you if you continue to fight the urges..."

Twilight held up a large bag full of freshly baked sweets along with two smaller ones.

"But you cannot, are not you? Oh, my goodness... look at your beautiful body! You are bloated like a pregnant one. How wonderful! All your fur is smeared with glaze! What a mess! Thank Celestia, you are finally going to learn to appreciate food!" Twilight giggled happily, "Are you ready for the next calories transferred massage? Let's do this in front of a mirror so you can see how fat is deposited on your body. Yes, let's put everything out here where we can admire it together. Come over to me, dear glutton princess."

Twilight laid Rainbow on her side with her magic and began to gently massage her belly. As she worked her way down, touching each part of Rainbow with care, the former flyer moaned softly. A new layer of fat is forming underneath.

"Soon, you will not need to fly ever again. Your muscles are melting away to nothing. Only your fat remains. You should savor it." At first, Rainbow tried to push Twilight's hooves aside. However, after several minutes of relentless massaging, she stopped resisting entirely. Soon, she just lay quietly letting Twilight work her magic upon her. She stared into the mirror, noticing how her stomach was deflated, but the rest of her body was slowly being covered with new rolls of fat. She was not even chubby now. She was fat.

Every few seconds, she saw the reflection of a blubbery equine mooch lying helpless before a smiling unicorn. "Ahh, what's the matter, sweet tooth?" asked Twilight. "Doesn't this feel nice?"

Rainbow shook her head slightly.

"No, please, I never want to be like this..."

"Then you need to stop overeating!" Twilight opened bag and poured sugar crystals everywhere. A big cloud of sweet aroma filled the room, almost choking Rainbow Dash.

With tears streaming down his cheeks, she felt her mouth watering uncontrollably. The smell alone made her tongue burn with hunger. But Twilight wasn't finished yet. She took small pieces of chocolate and rubbed them between Rainbow Dash's lips until they were coated in milk chocolate. Then she placed each piece inside the Rainbow’s mouth. Dash began licking frantically to swallow it whole. Finally, after making sure that Rainbow Dash swallowed all four giant chocolates, Twilight moved closer to her and started playing with her mane soothingly.

"Why did you eat this chocolate? Or maybe you want to be fat? Maybe you'd prefer a bigger belly? Of course, you wouldn't mind being sluggish forever, right? No pain, no gain you know? Is that what you wanted?" Twilight smiled mischievously, enjoying watching Rainbow Dash struggle. "Won't you tell me why you ate those candies?"

Dash didn't answer immediately. Instead, she closed her eyes tightly trying to suppress her emotions, feeling ashamed of herself for such weakness. Tears streamed down her muzzle silently.

"I want to stop overeating. But the food is too delicious. It smells amazing! I just couldn't help myself," she whispered sadly, burying her face in shame.

Twilight giggled softly. "So, you admit that eating things makes you happy?"

"No! Not ever!!" Rainbow snapped angrily.

"This is good. Otherwise, it wouldn't be interesting. I want to see you fight! Your anger! Your suffering! That's where my entertainment begins." She licked Rainbow Dash's cheek gently, lovingly.

Rainbow Dash whimpered quietly. Every fiber of her being rebelled against the idea of indulging in gluttonous behavior—but all thoughts of willpower vanished when Twilight gave her another slice of cake. The pungent sweetness overwhelmed Dash's senses. Suddenly she found herself unable to resist any longer.

"Yes...yes, do it!" Twilight grinned evilly through clenched teeth. "Eat! Devour! Make a pig of yourself! Stuff everything you've got into your fat little tummy and let us watch as it expands larger than ever before. Feel free to gorge yourselves on our treats, and munch away at these sweets until they're gone entirely! Eat 'til your heart's content, and we promise that nothing will prevent you from doing so!"

Rainbow sobbed. And indeed, she devoured the rest of the cake without further hesitation or pause. Each gulp tasted better and sweeter, causing her to swig more rapidly despite its overwhelming richness. The flavors seemed endless and insatiate. Just thinking about the end result caused her bulge to swell outwards painfully again. Yet somehow it still grew even greater within her abdomen. Dash screamed mentally at Twilight over and over again, pleading desperately for the princess to stop. Why must she constantly taunt and bully her like this?! All she ever wanted to do was train hard for the Wonder Bolts and prove that she was worthy of joining their ranks. How dare she treat her like this? Her treats are so delicious!

"According to my plan is to triple your weight today. Before going to bed, we will stuff your stomach again until stretch marks appear on your skin. Then tomorrow morning after breakfast, we shall give you yet more candy that will expand your belly even farther beyond belief. By noon, your belly should already be swollen to monstrous proportions..." Twilight stared directly into Rainbow Dash's tearful eyes. A wicked grin spread across her lips. "Either way, you'll be forced into immobility once you pass the point of no return. Isn't that, right?"

"...NOOO!!!" Rainbow choked out as she began cramming cake into her mouth faster and greedily. At last her belly felt almost uncomfortably full already. She gulped nervously and tried to slow down but it wasn't helping. With trembling hooves, she reached up tentatively and gingerly touched the distended, bloated mass protruding obscenely beneath her chin line. Was it truly happening...? Either way, she knew it was real—and terrifyingly so.

"You can stop eating at any time!" Twilight said slyly. "The moment you decide to stop overeating, I'll stop forcing you to stay here."

"I'll stop... in a minute...," Dash managed between choking breaths. Her words were cut short abruptly when she realized that a large glob of cream had slipped past her tongue and smeared itself along her chin. "I'll just eat another piece of cake No; I can eat two pieces in a minute... or maybe three pieces... Why did I say minute? I meant two minutes. As a result, I will eat six pieces of cake…"

As she spoke, she kept shoveling in bites of sweet confectionery blissfully ignoring that each successive swallow triggered a jolting pain inside her gut’s cavity. Soon that sensation morphed into sharp lancing pains throughout her midsection and lower abdominal region which steadily intensified as her belly ballooned outward toward the limit. Even worse, those discomforts combined with the fact that her own body suddenly weighed far more than normal made moving difficult.

"Look at those cute stretch marks on your belly! Looks like you're ready to burst! " Twilight giggled gleefully as she took several photos of Rainbow Dash's expanding gut. Rainbow's instincts told her to stop eating, but she didn't care because she needed to finish what remained of the cake even if she suffer a painful accident and die horribly in front of Twilight.

Twilight would finally leave her alone and let her rest peacefully without food. Despite the irresistible urge to keep gorging herself, Rainbow couldn't bring her body close enough to the table. Thus, instead, she spent nearly five excruciating hours napping and listening to incessant rumbling noises punctuated intermittently by grunts and burps whenever the pressure within her abdomen mounted above critical thresholds.

* * *

By evening, Rainbow woke up surrounded by the seductive aromas of food. Those smells drove away all thoughts of sleepiness as hunger overwhelmed her senses. Rainbow stretched out, shaking her new lush body. The dried cream on her fur began to peel off. Like a seal, she flopped over onto her side and rolled helplessly backward until she slammed into a wall behind her. From there she pushed herself up further, looking hungrily around the room trying to locate the source of such tantalizing odors.

"Good evening, Dashy!", Twilight greeted cheerfully from across the kitchen countertop where she stood watching Rainbow Dash struggle pathetically to right herself after falling backward during her clumsy attempt to rise upright once again. Twilight smiled knowingly to herself at the sight before her.

Still smiling pleasantly, she waited patiently as Dash eventually reoriented herself. "Welcome back to reality", Twilight added nonchalantly. She paused briefly to regard the struggling pony next to her curiously. "Did you lose your balance?", she asked innocuously as she moved forward slightly to study Rainbow more closely.

Warily, Rainbow looked straight at Twilight as she struggled to regain her footing yet again. Finally regaining stable support, Rainbow glared angrily back at Twilight. Though surprised, she retained composure well enough to hold eye contact unflinchingly despite the sudden flash of pure hatred she perceived.

"Hate you! Just look what happened to my body! I am fat!" Rainbow sputtered indignantly, pated accusingly at the growing bulge in her belly. Within seconds, a loud belch escaped her lips followed shortly thereafter by another one. Both sounds echoed loudly throughout the house.

Twilight nodded matter-of-factly, still staring intently at the mare whose shoulders trembled visibly beneath an accumulation of fatty flesh.

"Yes, yes you certainly do seem quite chubby today", she agreed almost conversationally, "but you know you needn't hate yourself for having put a little weight on".

With practiced ease, Twilight reached behind her for a plate stacked high with steaming hot pancakes covered with thick maple syrup drizzled liberally with cream over top. Turning back to face Rainbow squarely, the princess held out a pancake toward her trembling captive as she spoke softly reassuring words of comfort.

"You should understand that your body just needed some extra weight to match my preferences. I didn't force you to eat. Your current state simply reflects our desire." A subtle smile curled its way across her muzzle as she addressed the agitated pony directly. At last, reaching out, Twilight gently guided a large plate of warm flapjacks stack closer to the drooling Dash's mouth.

"I won't eat! I need to exercise to lose weight!" Rainbow demanded sharply, glaring balefully at the offered feast before her.

Twilight flashed a sharp gleam of amusement. "Certainly! But you are hungry! And to train, you need strength!", she explained calmly. As expected, Rainbow's eyes widened in surprise. "This whole situation couldn't be better suited to helping you achieve your goals," Twilight continued persuasively. "Just eat some pancakes before your workout! Come on... it will help boost your energy levels..."

"No!! No!!" Rainbow protested vehemently, shaking her head furiously and try backing away from her tormentor, "no more eating! Not ever again!"

"Just a light breakfast! A light breakfast for a pony-athlete. Smell these wonderful aromatics! Taste this sweet nectar!", cried Twilight insistently, holding out a fork full of fluffy batter toward Rainbow.

Tears welled up on Rainbow Dash's face as she stuck out her tongue and licked the treat. Already Rainbow felt her resolve wavering within her chest as she started to reconsider her earlier decision. All too quickly she found herself yielding to temptation. Reluctantly she took a bite and began to shovel it into her gaping maw. The act seemed to trigger a new hunger inside of her which rapidly grew exponentially until Dash realized she had devoured nearly half of the entire platterful. From there, things progressed at lightning speed as each successive bite forced upon her became larger than the previous one. Before long, even through her haze, Dash recognized exactly what was happening—her willpower was entirely gone. One bite and finally a gurgling burp left the helpless mare writhing uncontrollably as her stomach strained desperately trying to digest the massive amount of food stuffed down its throat. Still, however, she refused to relent or give up hope, instead of shouting defiantly between gusts of gas, " Please, please let me stop!"

"So cute! How did such a fit mare turn out so fat? Oh, come now, no need to deny it. Don't try to hide your shame", giggled Twilight cheerfully, stroking Rainbow's ample flank lovingly between two hoofs, "you've let yourself go! Of course, I will feed you! Whatever your problem may be, we shall solve it together."

Twilight added soothingly, placing both forehooves tenderly atop the mare's bloated abdomen as she leaned close and whispered in her ear seductively.

"Don't be embarrassed. We all overeat sometimes! What matters now is that you learn to manage your cravings properly so that they don't overwhelm you. You must never allow your appetite to get the upper hoof! Let's try again! Take a bite of this wonderful cake and then stop yourself!"

Rainbow hesitated briefly over the golden confection before taking the first tentative nibble. The taste alone made Rainbow gasp and moan softly. It was rich and decadent beyond compare and utterly irresistible. With a sigh and yet another belch, Rainbow reached eagerly for the next piece. Within moments she was enjoying herself immensely as she greedily crunched happily along.

The unicorn looked up smugly at Rainbow, seemingly satisfied that her plan worked perfectly. Dash’s stomach felt pleasantly bulging again, but not enough. But Twilight wanted to see an aching swelled belly, a gorgeous blue sphere, as big as an exercise ball and tight as an overripe watermelon.

"Eat! Chew! Swallow! Go on, my dear, finish the whole slice!", ordered Twilight insistently, pushing a third mouthful of sweet delicacy directly into the mare's gaping muzzle. "Ha-ha, this is just too funny...Whoops," she exclaimed suddenly, accidentally spilling the last bit onto Dash’s' coat.

"You should definitely drink plenty of fluids today...and tomorrow too!", she laughed merrily as Rainbow gulped obediently and drank away at the glass full of cola that seemed magically appear beside her. "Eat! Chew! Swallow... THINK OF NOTHING ELSE BUT FOOD!"

As Twilight finished speaking aloud her last words, Dash got lost deep inside her mind where thoughts didn't matter. Ah yes, absolutely nothing else mattered except eating. Tastes and flavors flooded through her senses until finally, everything stopped making sense altogether amidst a cloud of endless bliss. All Rainbow knew was hunger and pleasure. Everything was right and beautiful and amazing...and oh god, SHE LOVES THIS CAKE!

The floodgates were opened and Rainbow couldn't hold back the urge to gorge further. Her tongue darted out hungrily and lapped greedily up each morsel that fell upon its surface. Every second brought fresh delight which caused her to writhe and squirm ecstatically beneath Twilight's ministrations. Soon after the mare had eaten entirely half of the cake by herself, she found herself unable to move an inch due to sheer satiety. That wasn't quite good enough for Twilight Sparkle though. She needed to see the mare stuffed right to capacity.

Rainbow was still too full to even consider moving an inch. How she hated this feeling. The mare felt she might explode at any moment. Her insides seemed to be threatening to burst through her skin at the slightest provocation. "Just one more piece, Rainbow", urged Twilight. "Have another bite..."

Rainbow shook her head slightly, refusing to chew or swallow anymore. "I can't eat anymore..."

Twilight sighed and smiled sadly. "Of course, you can. You'll keep eating until you collapse. Look at you, you're already so plump and round. Your tummy looks so nice and swollen. Just look at that cute growing dome." Rainbow groaned but couldn't do anything else but watch helplessly as Twilight shoved the final piece of cake into her mouth and motioned for her to eat.

Her eyes rolled back in her head and she collapsed to the floor. Unable to control her own body, Dash mewled pitifully as she desperately tried to find a position that would allow her to breathe normally. The pressure began to build and her stomach burned like fire.

"That's not enough now", she declared firmly, pushing a few remaining crumbs into Rainbow's waiting jaws. "Go on, Dashy...finish it all off..."

"Please, no... I can't... I'm sorry..."

Twilight reached down to grab the filly's hoof and squeeze it tightly. "You should be. You've been such a greedy little pony. You've stuffed your face so much, I just had to make you immobile. Forever. I'll never let you escape."

Dash saw her reflection. Her muzzle was so huge! So round and fat and soft and tender and so... so filling! Her cheeks bulged outwards. The way she stared at her own reflection made her realize how disgusting she must look. What a disgraceful sight to behold. Dash's eyes widened and the sight of her own bloated body sent a wave of nausea through her.

"No! No, please!" she screamed. "I'll do anything you ask! Anything, just don't make me immobile!"

"Nonsense!" Twilight looked at the mare, smiling with glee as she thought about what she was going to do next. "You know what? I think you're starting to like this. I think you're beginning to enjoy this. Maybe that's because I'm doing this so well, huh?"

Dash could only moan in response. "Please, no..."

Twilight grinned wickedly and rubbed her hoof along Rainbow Dash's tummy.

"What's that? You don't like that idea? I'm afraid you don't have a choice. I'm going to make you love being stuffed. I'm going to turn you into a gluttonous, overgrown pony. A gorging, greedy, gluttonous mare. I bet I can make you love this..."

Rainbow gasped as Twilight's hoof slid across her belly. "No..." she moaned. "Please, stop."

Twilight smirked at the mare's reaction, continuing to stroke Rainbow Dash's sides and belly.

"What if I make you get turned on by imagining yourself fat? And when you swallow food, you will cum like never before. How would you like that? Oh, don't worry, Rainbow Dash. You're going to love it. Take a bite of this delicious cake. And feel free to enjoy yourself while you stuff yourself silly. The more you eat, the more your belly will grow and the more powerful the spell I'm going to cast on you will be, making you an even more greedy glutton. So, go ahead. Enjoy your food."

Twilight Sparkle smiled at Rainbow Dash. Her expression was calm and serious. "Okay, Dash. Time to have some fun. I will make you beg me to feed you. And when your stomach is ready to burst, you will beg for more food. Sounds good?"

"No!" said Rainbow Dash shakily after taking several deep breaths. "This will never happen!"

Twilight laughed. "Oh, don't worry," said Twilight calmly. "You're going to love it. Just sit tight until my magic takes effect. Then we'll find out whether you've got what it truly takes to be a complete piggy girl."

With Twilight's encouragement, Rainbow began eating faster. With each second passed, her hunger grew stronger. Her mouth watered greedily as she devoured chunks after chunks of sweetened sponge cake. Although the mare felt full already, she still seemed insatiably hungry. As Twilight stroked the inside of Rainbow's thigh muscles, the mare quivered excitedly beneath her touch. "Any moment now... any minute... Dashy" whispered Twilight gently as she caressed the mare's thighs, sending shivers throughout the pegasus' trembling frame.

Suddenly, the next swallow made Rainbow cum. So powerful and unstoppable, as if it were physically impossible to hold back such pleasure — and yet somehow Dash managed to fight through it all just to continue swallowing Cake! Each subsequent orgasm became longer and deeper in its own right. As if her tongue, throat, and stomach were transformed into the lusty vagina. Fleshy vices were designed specifically to grant her endless amounts of orgasms and satisfy her inexhaustible appetite. Soon enough, Rainbow's entire midsection expanded rapidly with each new swallow. All along, Twilight remained amused by watching Dash squirm helplessly underneath her expert ministration. Every gulp caused Rainbow to writhe uncontrollably and spasm violently in ecstasy.

However, Twilight refused to release her prey thus far going into gluttony. Twilight forced a huge gobbet of frosted white cream past Rainbow's lips directly onto her muzzle where she lapped away hungrily, ignoring everything else happening around her except the taste buds dancing upon her tongue. Her eyes rolled wildly behind her eyelids as she struggled to endure the incredible onslaught of sensations that assaulted her mind. Forcing her unwilling lips wide apart, Rainbow gulped thick slices of buttercream icing straight from the mixing bowl onto her tongue. Sweets swirled over top of itself as rainbow swallowed compulsively slurp gulpy smacking noises escaped between Rainbow's teeth. Lapping frantically at the bowl filled to capacity with sugar frostings. Thick layers of creamy lard dripped down her chin – sprinkling her neck fur with powdered sugar sweet toothsome delicacies– as she gobbled like a gluttony pig. And she wasn't going to stop. Every bite increased her desire to gorge even further. Yet despite having consumed several gallons worth of cakes and candies, she still wanted MORE!! Her belly churned with overwhelming cravings for more sweets to fill the empty void inside herself. Sweet food was a drug that she could no longer live without. And every last bit of cake disappeared into Rainbow dash's gaping maw. Only then did Twilight finally allow her captive time to rest. Twilight looked upon her subject with satisfaction. "Well done, little mare. I think if you continue today, your stomach will burst."

A dazed look crossed Dash`s eye sockets as she gazed blankly at nothing in particular. Some drool ran freely over her lips and dribbled down her cheeks forming large sticky puddles below her snout. Panting heavily to regain her breath, Rainbow closed her mouth tightly shut-in order to try and prevent future messes. That didn't work out too well, however...as she began burping loudly after inhaling air quickly. Soft belches came forth from her maws accompanied by loud gasps. Through her blubbery lips, Rainbow spoke softly to Twilight, "I haven't felt this full since my mother gave birth to me! But I want more... food..."

The princess giggled happily, "That's exactly what I hoped to achieve. Unfortunately, I won't give you more food until tomorrow. But you can try to beg me to feed you. This will amuse me."

Loud rumbling gurgling echoed throughout the room as Rainbow tried desperately to remain conscious through sheer willpower alone. If she were allowed just ONE LAST MEASLY BITE OF CANDY she'd do ANYTHING FOR IT!

"Please Twilight...PLEASE!" Dash cried tearfully, nearly losing consciousness from hunger building within her gut.

Hearing such pleading words coming from her prisoner, made Twilight smile gleefully. Twilight rather enjoyed hearing other things besides groans and grunts emanating from her formerly agile companion who now resembled a balloon.

"Please, please, PLEASE!!" Rainbow shouted again, tears streaming uncontrollably down both eyes as she stared directly into those of the alicorn mare. "Just one more snack!"

"Your belly is too stuffed already, fatty," Twilight said soothingly. "You've overeaten far beyond reason today. Let us call it quits here."

Looking somewhat disappointed, Rainbow looked away to the side where she saw two huge bowls filled to capacity with colorful candies scattered across each table edge. Seeing these confections caused her insides to churn wildly once more inside of their confines and new feelings of despair and longing started surfacing deep beneath all that extra flab. Unknowingly, Rainbow began rubbing her bulging tummy in hopes of alleviating that feeling that rapidly took hold of her entire psyche after enjoying so many sweets. Suddenly overcome with emotion yet unable to identify why Dash broke into a sobbing fit similar to that of a small filly whose favorite toy suddenly breaks apart right in front of its own helpless little hoofs.

As if reading her mind, Twilight tenderly placed a kind wing upon Rainbow's shoulder and cooed gently in reassurance, "Don't worry, slobby ~ We will satisfy your hunger tomorrow. Let me admire your cute tummy. It looks SO plump and fluffy~"

With great reluctance at first, Rainbow reluctantly lifted her head upward toward Twilight's gentle touch and let her gaze wander upwards along with the unicorn mare's beautiful figure over top of her now shapeless blue coat. Realizing instantly the purpose behind such actions, Rainbow immediately lowered her muzzle lower to hide her shame with embarrassment and put her ears flat against her skull to cover up the belching sounds escaping her lips. A certain pink blush spreading quickly across Dash's cheeks. Still gazing straight ahead, however, Twilight quietly whispered reassuring phrases like "You mustn't blush. You are beautiful..."

As she spoke, Twilight reached out a delicate forehoof to lightly caress one cheekbone and whisper sweet nothings that seemed to melt Dash's heart ever further causing a bright red hue to the color. Allowing Twilight to continue doing so for quite some time, Dash eventually found herself smiling softly beneath that pair of big glowing orbs staring lovingly into hers.

Twilight could hardly believe how much food her captive had eaten.

Every inch of her body was covered in chocolate chip cookies, and her tummy was so big that it looked like she was wearing a giant balloon. Seeing her pony friend look so delicious was enough to drive her crazy. She wanted to devour her, lick her, suck her. She sat down next to her captive and started rubbing her friends massive belly. Rainbow moaned in pleasure as her captor's hoofs rubbed against hers. Then Twilight leaned forward and kissed her captive on the lips, and the moment she did, a massive burp escaped Dashs mouth. Twilight smiled with delight as she heard her friend fart loudly. The smell of chocolate and sugar was overpowering, but Twilight found it intoxicating as well.

After a few moments of kissing, Twilight pulled away and licked the remaining crumbs from Rainbow's muzzle. Rainbow moaned as she felt Twilight's tongue cleanse her nostrils. Then Twilight moved down to her ears, licking them delicately until they were shiny and wet. Rainbow giggled uncontrollably as she felt her pony friend's tongue massage her sensitive ear canals. After a few minutes of this treatment, Rainbow was moaning and writhing in ecstasy as her tummy rippled with the vibrations of her climax.

The feeling of her friend's tight, smooth tummy was enough to send Twilight over the edge as well. As she rode out her orgasm, she leaned down and whispered into her friend's ear, "I'm going to turn you into a fat, immobile slob. You'll never fly again."

Rainbow Dash trembled as she felt Twilight's hot breath wash over her ear. Twilight licked her own lips in anticipation as she pictured her captive pony being able only to eat, burp, and defecate. The thought of this beautiful pony trapped in her own body was enough to make Twilight weak in the knees.

"You're so beautiful, Rainbow," Twilight purred as she nuzzled her friend's cheek with her nose.

Rainbow shivered as she felt Twilight's hoofs rub against her flank. She didn't know what to do, but she knew that whatever happened, it would be bad. So, she allowed herself to fall deeper under Twilight's spell. Twilight took her captive's muzzle in her hoofs and bit down lightly, causing Rainbow to moan with pleasure as she tasted her friend's sweet saliva. Twilight's hooves massaged her captive's flanks as she breathed heavily in her ear, "You'll be mine forever now, Rainbow. My pet, my plaything, my slave."

Rainbow whimpered as she felt Twilight's tongue trace her jawline. The mare was afraid to resist, but the thought of her body turning into a fat, immobile slob terrified her. Twilight smiled as she felt Rainbow tremble beneath her touch, "Your body belongs to me now, Rainbow. You're my prize, my reward."

Rainbow gasped as she felt Twilight's hoofs dig into her tummy, pressing her stomach. The loud burp that followed caused Twilight to smile as she rubbed her friend's belly, "Now that you've eaten all of your food, I'm going to put you to sleep, Rainbow. When you wake up, you'll be a fat, immobile slob."

Twilight kissed her captive's forehead before pushing her onto her side. Rainbow Dash moaned softly as she fell asleep, but Twilight couldn't stop smiling.
