Inevitablity

Twilight woke up, noting how much her stomach and jaw ached. The feedbag was still attached, and every so often, Twilight's mouth would take a huge bite of lasagne to keep her constantly full. It hurt more than Twilight had anticipated, but some niggling thought at the back of her head was saying that the pain felt good-

“Hey, sugar cube,” Applejack called from the kitchen, “I was getting worried you wouldn't get up. Do you mind waking up Fluttershy? She's been sound asleep, even after Pinkie Pie knocked over that stack of pans.”

Twilight nodded, sliding out of bed, feeling her new girth wobble and jiggle. She waddled over to the slumbering Fluttershy, and carefully shook her awake. Fluttershy sat up with a startled gasp, waking up instantaneously, then remembered where she was and who she was with.

Twilight would have offered a comforting smile, but the feedbag blocked her completely. She instead, waddled over to Rainbow, who was reading a Daring Do book, propped open on her stomach and using one hoof to keep it where she could see. Twilight poked Rainbow's belly, and gestured to the book. Rainbow impatiently held it up so Twilight could read the front cover, then set it back down.

Twilight sat beside her reading friend, wincing as her mouth took another mouthful of lasagne. Sweet Celestia when this ends, my f ace is going to hurt so much.

Static filled the room, causing each pony to freeze in place, all looking up at the nearest camera.

“Hello Twilight Sparkle,” The voice said mockingly, “Oh dear, have you fallen ill? You look so uncomfortable with that feedbag on. Would you like me to remove it?”

Twilight couldn't help but nod vigorously at the idea, hoping perhaps the voice held some sympathy-

The voice erupted into loud laughter, “Silly pony. Do you honestly think I'll let you plateau in your gains? If I do that, my employer will be incredibly displeased.”

Twilight both saw, and felt, his blue magic envelop her. Twilight felt warmth spread across her body before she felt her already massive body swell farther with fat. Her stomach felt completely empty, crying out for food for just a moment before her jaws began to work overtime, trying to fill the void in her stomach.

The voice laughed again, “There we go. This is a little spell my employer devised just for you six. Whenever the feedbag fills you to your absolute capacity, the spell will activate. The calories you don't use for existing will be converted into straight fat, and the feeding cycle will begin again.”

Rainbow looked horrified, the book laying open and forgotten on her uppermost stomach roll. Twilight felt tears well in her eyes, but she forced them back; she would cry later.

“How are we not dead, if you don't mind me asking?!” Rarity piped up suddenly, glaring into the nearest camera, “All of us should be experiencing a great deal of health problems right now, and we don't seem to be having any health problems at all.”

“It wouldn't be any fun if you all died because of clogged arteries, would it? During the months while you and everypony was 'asleep', we introduced new substances into the water, air, and food supplies that makes it almost impossible to die of a heart attack due to obesity.”

“That's not even possible!” Applejack shouted, “How did you even make something like that?”

“Years of research and a lot of magic, my little ponies. Now, if you be good I might be able to let you go soon, as you're all growing so well. I would like you to eat something at all times, except for when you're sleeping. Hop to it, ponies. We still have your friends and family.”

The static ended. Twilight sighed, leaning farther into her chair. Rainbow looked stunned, her wings flapping weakly on impulse.

Applejack sighed, “I guess it's a good thing we've already made lunch then, isn't it? C'mon girls, lets get this over with. The more we eat the sooner we can get out of here.”

Rarity, laying on her stomach on her bed, began to try to get off the soft surface. When she finally shuffled her way to the edge of the bed, she was panting heavily. Once her hooves touched the ground, however, they gave way under her immense bulk. Rarity landed on her soft stomach with a startled cry, then realizing her problem, began to sob horribly.

The others did their best to calm her down, and Twilight used her magic to help lift Rarity up as Pinkie, Fluttershy, and Applejack all heaved her back onto the bed. Unlike Rainbow, Rarity lay on her stomach, her soft belly acting like a second mattress. Her thick legs, and massive plot, were almost hanging off the sides of the bed.

Twilight wondered to herself how they'd missed how large Rarity had become. Then, she remembered that in the last few days, Rarity had done little but lay on her bed, eating. Twilight felt her fear ramp up. Who would be next? Herself? With how much lasagna she was eating, coupled with the spell, it wouldn't take much more to make her immobile.

As if in reminder, she felt magic envelop her again, and Twilight watched in horror as her stomach dangled lower, pushing her thick legs apart even more. Her stomach cried out for food once more, and her mouth greedily began working again. Twilight waddled slowly over to bed, and adopted a position similar to Rarity, this would certainly be more comfortable than sitting upright for the rest of her life.

Rarity watched, her big blue eyes still shining with tears, “What are you doing?”

Twilight glared at the other unicorn over the feedbag. She sighed, wincing at the sudden harness of her stomach. Celestia, this hurts more than it should.

“I think she's getting ready!” Pinkie called from the kitchen, “She's almost too big to move, so she's getting ready while she still can.”

“Is that true?” Rarity's chins wobbled as her mouth moved.

Twilight nodded, relaxing her position so she was as comfortable as possible. Immobility was an inevitable consequence of their captivity, and for Twilight, there was nothing to do but wait.
