New Diet

She could hear her roommate coming down the hallway to their apartment easily. Not only was her roommate hooved, but quite heavyset. She walked over to the door with glee, ready to welcome her back from her shopping trip. As the hooves stopped in front of the door, she swung it open to reveal a heavy-set cow with bags of groceries on her arms. They squealed at each other a little bit before she stepped aside to allow her friend to squeeze through the door frame.

The other roommate was a considerably smaller guinea pig. She had mostly white fur with a small series of black dots on her back, as if trying to mimic the cow. Her friend dropped the bags of groceries in the kitchen, then walked over to and fell on the couch. She sighed, “Whew! Charlotte, you would not BELIEVE how expensive some of the healthy food is. I think I blew most of our budget for the rest of the month.”

The guinea pig sat down next to her roommate and said, “It'll be worth it Ellie! After all, we wanna get you all trimmed down for the boys. I think your new diet will work.”

Ellie hugged her, thankful for the constant encouragement. “Is Margo here? She'd love this.”

“Nah she’s out somewhere. I think it's better this way, she might mess something up y’know.” Returning to the topic, Charlotte asked, “Okay, sorry to ask again, but how is this gonna work?”

The cow nodded and took a deep breath. “Okay. So basically, before I eat, I'm gonna swallow you so you'll just fill me up. That way my body won't feel like eating so much and when it thinks I'm full, I can just spit you out and that way I won't have eaten so much food.”

The guinea pig nodded back, remembering being told about the diet before. It seemed fine by her. Cows are herbivores so it was totally 100% safe. She was small enough to fit inside her friend without her bursting, so she was a perfect fit for the diet. Charlotte suddenly remembered something, reaching off to the side of the couch. “Oh by the way, here's…” A laptop was brought up. “To record your dietary journey!” She leaned forward and placed it on the table in front of the couch, angling it to get a good view and setting up the recording program.

The two anthros shared a moment of silence as they locked eyes on the couch. It lasted for only a few seconds, being interrupted by the familiar growling from the cow’s guts. Ellie patted it and said, “Well! I guess it's time. Ready?”

Nodding, she said, “Yup! Just let me start recording and take off--”

Having only just barely pressed the record button, the still-clothed rodent had her head wrapped by drooling pink flesh. A tongue lapped against her cheek while blunt teeth dragged across both sides of her face. Hooves scooped her up, raising her to a horizontal position for easy consumption. The webcam, now recording, watched as the cow began easily swallowing her friend. Ellie’s throat bulged with the furry rodent, who was kicking weakly and complaining about her clothes being ruined. The bovine’s face was apologetic, but she really wanted to start on her diet. She used a hoof to push the rest of the guinea pig in, then closed her lips around the end. With a hard and audible gulp, a large bulge could be seen traveling down her throat, then stopping as a decently sized lump in her already large stomach.

Ellie let out a delighted and loud burp, patting the friend-shaped bump in her belly. Said bump finally got to say, “Ellie! My clothes are totally ruined now!”

As the cow got up to dig through her groceries she replied, “Sorry Char! But I was really hungry. Speaking of which, get ready!”

Charlotte adjusted herself just in time for lightly chewed chunks of lettuce to start falling onto her, further ruining her clothes. She groaned, but found some comfort in her friend’s stomach being even mildly comfortable. She filled most of the rumen, but was still able to shift somewhat, in addition to being shifted by the walls. With nothing to do, all she could do was listen to the sound of repeated chewing and swallowing. The cow’s belly tried to sort her out a few times, but a whole anthro guinea pig was far too big to do anything with. Too big to really ferment, too big to be stored away.

Many vegetables and some junk food made their way in around Charlotte. Lettuce, carrots, bread, chips, cheesy crackers, soda, and finally what was probably a cupcake. She thought to herself that if all of the food around her was ‘dieting,’ it was unlikely for Ellie to lose any weight at all. That said, it did seem like she was finally done eating. Which was fine by her since it seemed like the rumen was running out of space. It seemed to be ignoring her at this point, dealing with the actual food.

On camera, Ellie had finally returned to the couch after roaming around the apartment for nearly half an hour. Her gut now was more solidly round, Charlotte’s outline having been buried beneath food. “Ohhhh that was great,” she said dreamily. A hoof rubbed around her belly as she sighed. Then she nearly jumped out of her seat as her belly moved a bit on its own.

It said, muffled, “You all done up there, El? Can I come out now?”

The cow laughed and said, “Oh Char, I nearly forgot you were in there! So small. Um, sorry, but is it okay if you stay a while longer? I just need to take a food coma for a bit.”

Charlotte sighed, remembering her trademark food comas. “Alright. I'll just be here, filling up space.”

Ellie cheerfully said, “Thanks sister! I-- blorrrrrupppp-- I really think it's working. You could just like, sleep in there too to pass the time if you want.” She yawned, patting where she believed the guinea pig’s head to be. Then she settled into the couch and promptly passed out.

Despite being surrounded by chewed up bits of food, Charlotte did consider sleeping. It was very warm inside the bovine, and the food made for a soft bed, even as it fermented. She felt her eyes get heavy and her mouth let out a yawn. This wasn't that bad after all…

*/^\*

Not more than a minute later, Charlotte jerked back awake as she heard the door to their apartment slam open, over the digestion. Ellie remained fast asleep, her tongue lolling out of the side of her mouth. The ‘intruder’ was easily identified as their third roommate, a drunk goose by the name of Margo. She shouted, “How are my two favorite mammals?” Scanning the room, she only saw a sleeping, bloated cow. A bit confused now, she walked through the other rooms in the apartment, unable to find the guinea pig.

Back in the living room, she sang, “Queen Charlotte, where are you, your Majesty?” A seemingly distant reply turned her towards the sleeping cow. And looking closer, she saw the source: Something inside said cow, struggling slightly. The goose walked over and said to the belly, “Queenie? Can you hear me?”

Charlotte replied, “Hello Margo.”

Margo considered the situation and said, “So I guess Ellie here finally got fed up with you.”

“Please. I'm helping her out with her new diet.”

“Oh, I see. Does this diet include living animals or…?”

“No! I'm just filling up space so she doesn't eat as much.”

“Oh alright. So what uh, what's happening right now?”

“...She’s sleeping off her food.”

“So are you gonna get out or what?”

“When she wakes up!”

Margo chuckled and said, “Well, I’ve got nothing better to do...” She finally noticed the laptop and said, “Oh hello! Recording all this. I'll have to watch that too, later. For now…” She headed over to the fridge, searching for any alcohol. With a silent fist-pump, she grabbed a bottle of wine and headed back to the scene. She took a seat on the table, next to the laptop.

The next ten minutes after Margo’s arrival was externally uneventful. Inside, Charlotte experienced the cow’s rumen starting to sort out its contents to the best of its ability. Solids, liquids, and produced gases each separated out, and the guinea pig was pushed around to different parts of her section. The spectator outside made a drinking game out of trying to follow her movements beneath the skin.

Ellie suddenly started to move outwardly, though it was nothing more than ruminating. She let a belch out, then smacked her lips and reeled in her tongue. Still asleep, she started chewing on regurgitated cud. It grossed out Margo to watch so closely, but she remained nonetheless. Charlotte was also grossed out by the increasingly mushy food coming and going.

Then all of a sudden, the muscles started pushing her in particular. Her hopes rose as she was squeezed back up the crushingly tight throat, getting a blast of cool air from between the bovine’s lips. She reached forward to pull herself out, but instead blunt teeth started to gently gnash on her front half. She squeaked loudly, causing Margo to notice the guinea pig being chewed on in Ellie’s maw. The goose guffawed, not listening as Charlotte begged for Ellie to wake up and let her out. She was so close-- but then she was swallowed back down again.

After a few more minutes of being stirred with the digesta, Charlotte was sent back up. This time up she realized that her skin felt extra cool, but she couldn't realize why while being licked and teethed on. She noticed the amused goose watching and shouted between lip movements, “Help! Me!”

The goose shrugged. “I can't ruin her precious diet, right?”

The guinea pig shouted back, “You f--” Gulp.

Back down in the rumen, Charlotte found it to be somehow more hostile than before. It seemed very active, pushing her around to uncharted territory. Before she could get a grip on her surroundings, she, liquids, and some other food were forced through a tight hole. She yelped as she passed through it, being shoved into a very tight chamber on the other side. There was zero room to shift here, only to punch or kick slightly. The fleshy walls here had different textures, and the deeper movement into Ellie made her feel unsure about the safety of being eaten by a herbivore.

Outside, Margo was stunned by the movement to a new sector of the cow’s belly. She delicately fondled the lump Charlotte made and took another swig of wine. The goose was even more amazed that Ellie could sleep through all the action going on inside her. If she had swallowed a stuck-up little guinea pig, she would enjoy every moment of digestion. Though maybe the rodent would survive. What did she know about herbivores? She was five beers and half a wine bottle deep.

Charlotte wanted to help thin her friend, but between being prodded from outside and dried out by wherever the hell she was, she was pretty done. Unfortunately, all the kicking and shouting in the world didn't seem like it'd wake up the cow, and the drunk outside sure wasn't helping. She tried to feel around for the way she came in, but it didn't seem like she was going to find it. Being surrounded by dry, ground-up food and various fluids didn't help much either.

After a torturous while longer, it seemed like Ellie’s gut decided it was time to move on. Charlotte felt herself start to squeeze through another sphincter, feet first this time. It felt roomier, a source of instant relief to the guinea pig. Maybe she was moving back up to actually be let out? Then as she popped through fully, a harshly acidic smell struck her. This chamber was slightly roomier than the last, and she splashed into a stinging liquid on her back. Her heart sank as she noticed all the similarities of this chamber to the single stomach of other carnivores/omnivores. She became frantic and shrieked, “No, no, no, no!”

Margo was hooked into the action by the turn of events. She watched through the empty bottom of her bottle as dents appeared and faded, while the sounds of shrieks and gurgles competed for dominance. The fight didn't last long, gurgling and groaning overcoming the guinea pig. She herself became mush, albeit much later than the rest of the food. The goose poked a few more times with the mouth of her bottle, finding great amusement in the much softer belly. She raised her bottle to Ellie, still sleeping with the occasional belch and chewing. Then Margo fell off the side of the table and passed out on the carpet.

*/^\*

Ellie finally woke up much later than she expected. She sat up, stretching her back and immediately noticing a pressure in her lower gut, which she ignored. Wiping drool off the side of her face, she smacked her lips and turned towards the goose passed out on the ground with a wine bottle. “Margo…? What happened after I fell asleep?”

The goose shifted a bit and whispered, “Tasty piggy…”

She wasn’t sure what to make of that remark and instead scanned the rest of the living room. The laptop was still on, recording, almost at 12 hours now. The cow stopped it, leaving the computer to try and save the massive video. As Ellie stood up, she noticed that she felt heavier and looked fatter than other binges had done to her. She supposed her diet had failed after all. Stepping over the goose, she started to head down the hallway in search for Charlotte. Each room was empty, but before she could consider those results she needed to rush into the bathroom.

Almost thirty minutes later the cow emerged. Margo was a bit more awake now and watched as her roommate walked shamefully down the hallway. The goose leaned her head back down and said, “Did you find her?”

Ellie quietly responded, “No…”

Smiling a bit now, she sang, “Are you suuuure?”

“...Well…”

“I guess that diet didn’t work out, huh? Ohhh well.”

Looking down past her sagging gut at the surprisingly calm goose, she felt surprisingly calm as well. A hoof rubbed gently over her belly, that being the only other remains of the guinea pig. Maybe it was fine that her diet didn’t work out. Turning back towards the laptop, she realized that she should at least do one thing. Using their video, warn the internet about the dangers of this diet and discourage anyone else. Even though later on, her roommate would use the same video to encourage certain groups she knew. No reason to let all of the guinea pig go to waste.
