An Uplifting Experience

Fwip!

Sunset Shimmer was up early. It was a busy day ahead for her, she was already thinking about the small speech she had been up late last night preparing to give at the School of Friendship later in the day. Twilight had asked her to come along to “Pep up the students for the start of the year” and talk about her unique experiences back home. It was a bit of an ask, she was getting ready to go and get the early train to Ponyville to make sure she arrived there in time. Her cousin Diamond Sun was letting her stay in her home in Canterlot for the time being. Most of what she was doing was taking place in the city anyway, this would just be a little jaunt out to help out another friend.

She looked towards the door, the mail had come through the letterbox and of course most of it was addressed to Sunny. She laid it neatly on a table except for a flyer with bold text and a rather buff looking stallion next to some weights taking up the majority of the space in the middle of the page. It proudly proclaimed “UPLIFT GYM - UPLIFT YOUR PHYSIQUE!” with more details down the page. Various classes, equipment and the heavy set stallion in a rather adorable looking speech bubble shouting ‘I never work out anywhere else!’. There was some oddities on the flyer, while it did talk about what went on at the gym it listed a copious amount of shakes and other supplements they offered for their members, as well as stating that new members got heavy discounts on them, or even freebies if they hit particular weight goals. The flyer did not specify what these goals were. The bottom had a small part you could tear off to take to the gym to sign up with blank boxes to fill in your details. Sunset was about to put it aside and head out for her train when she felt a bump at her side.

‘Ohhh, something good in the mail?’ Sunny had appeared next to her. Sunset had tried to be quiet on her way out, but guessed she had woken her up.

‘Junk more like.’ Sunset said, magically passing the flyer into Sunny’s hooves. ‘Although…’ she giggled, giving Sunny a small prod into her side. ‘You’re not exactly the trimmest pony out there. A spell at the gym might do you good.’

‘Oh please, me?’ Sunny prodded Sunset right back. ‘Mrs hey are you gonna eat that?’ she laughed. The pair had gone out for dinner last night, Sunny hadn’t quite finished her food and the question had come. She remembered passing over the remains which Sunset had quite quickly eaten.

‘I’ve been busy!’ Sunset retorted. ‘You know, working. It makes me quite hungry.’

‘Yeah, but you don’t work it off.’

‘Well neither do you.’

Sunny raised the flyer to her face and read down the page. ‘You know this might be the cheapest gym I’ve ever come across. You think it has something to do with all the offers on these shakes?’ she asked Sunset, pointing to the part of the flyer that highlighted it.

‘Maybe.’ Sunset replied. She was aware she needed to go in the next few minutes. Perhaps it was needing to get away. She could foresee talking to Sunny for the next twenty minutes and missing her train, but it seemed like the obvious way to end the conversation. ‘You’re off today. Why don’t you sign us up and we can both get in shape? They have a branch right here in Canterlot.’ Sunset said, pointing down towards the bottom of the flyer that held the address. ‘Can’t hurt to at least try. Look “Your first five sessions free, no charge if you don’t continue.” she read on the flyer. ‘Both of us could use getting into better shape.’

‘Alright.’ Sunny simply said, placing the flyer down with the rest of mail. ‘I’ll let you know about it when you’re back tonight. Will you be late?’

‘I don’t know, Twilight wants me to give this talk then I’m not sure what else. I’m sure it’ll turn into a longer day than I am expecting.’ Sunset answered honestly. ‘You know what she’s like.’

‘Well, I’ve heard.’ Sunny replied. ‘Anyway have a good day. Don’t miss your train.’

‘Leaving now!’ Sunset yelled, shutting the front door quite hard behind her. Sunny grimaced, she probably just woke up half the street. She picked the flyer back up again. The mare decided to get a few more hours of sleep before heading out for the day. Perhaps she would swing by the gym.

-

A few days had passed and the weekend had arrived. The Ponyville excursion had been somewhat longer than Sunset had anticipated. She had just caught the last train back to Canterlot that day and returned home long after Sunny had gone to bed. The gym conversation had long since exited her head and she was quite enjoying a lie in when her slumber was disturbed by commotion. Sunny was leaning over her in bed, grinning.

‘Morning sleepy head. First day at the gym!’ she beamed.

‘Hurgh?’ Sunset about managed a response then opened her eyes, blinking. ‘First day at the what?’

‘The gym. Come on Sunset it’s only been a couple of days since you practically forced me to sign us up.’

The memory then came quickly flooding back. The final words before she had trotted out the door at pace to get that train. She had been mostly joking and needed an exit. She didn’t believe Sunny would actually do it, but it seemed she had. It then only lead to one further question. ‘Why are you up so early?’

‘Well when I signed up they said it was pretty quiet in the morning. The pony I spoke to suggested if we started earlier we’d get a run of most of the gym. Then we can spend the rest of the day as we please. Sounds good, no?’

‘No Sunny, you know I’m not a morning pony.’ Sunset groaned. ‘At least give me ten minutes to get up.’

‘Alright, but if you’re not up and out of bed in ten I’m coming back.’ Sunny replied, leaving the room and shutting the door behind her. Sunset lay there for five minutes, but it was no good. She was awake and figured there was no point trying to go back to sleep anyway. She dragged herself out of bed and started to get ready, hopefully at least a breakfast would be waiting for her when she wandered downstairs. Sunny made pretty good pancakes.

What was waiting for her was not pancakes.

‘Why is it in a plastic bottle and why is it pink?’ Sunset asked, looking at the suspicious liquid. There was a hole at the top for sipping it out of. Sunny had put two of them together in place of the usual pancake plates at the breakfast table.

‘Well when I signed us up they gave me a small joining parcel, these were inside. It’s their own brand of shakes. The pony I spoke to suggested drinking them before, during and after a workout session so I figured we’d have the first ones now before we go to the gym.’

‘What’s it meant to be?’

‘Strawberry.’

‘With?...’

‘With plenty of protein I am guessing. They were quite keen to mention their shakes have a lot in. The pony I spoke to who was working on the check in desk said she drinks a lot of them.’ Sunny explained as Sunset took a first tentative sip of the shake. She swished it around in her mouth before swallowing, then looking at what remained.

‘It’s pretty nice. Almost actually like a shake that isn’t healthy.’ she said as Sunny took a sip of hers.

‘Oh yeah, I see what you mean. Very sweet. Well at least drinking them will be nice. They gave me other flavours as well!’ she said, taking more sips of her drink. Sunset did the same.

The drinks were finished rather quickly. The thoughts of pancakes had gone from Sunset’s mind. She rinsed out the empty milkshake jug and looked around for a bag to bring it with. As she glanced around, she noted Sunny grinning.

‘What?’

‘Something to carry it in right?’

‘You read my mind.’

From behind the table Sunny pulled out a couple of bags. A white one and a yellow one to match their coats. Cylindrical with a zip down the middle, gym bags.

‘Ah.’ Sunset said, taking the yellow one, assuming it was hers.

‘I thought it would be handy for the shake containers, towels and anything else we might want to bring. I found a shop in Canterlot selling all kinds of bags, but these are for the gym!’ Sunny beamed, washing her own container out then placing it in the bag. ‘So, shall we?’

‘The sooner we start the sooner we finish.’ Sunset said, she was more looking forward to the day ahead than the gym session.

‘Aww, don’t be like that. It’ll be fun!’ Sunny replied, hitching the bag around her so it was easy to carry on the way. Sunset followed suit, just using her magic.

‘Alright, lead the way.’

-

The gym was a rather stand out structure in the town, clearly purpose built and new. Canterlot had a lot of old, rather ornate buildings that looked rather pretty. The gym was blocky and utilitarian. It looked like the designers had tried to incorporate a little whimsy, most likely at the request of the city council, but it was extremely minimal. The large sign simply read “UPLIFT” in bold letters like on the flyer. It was in a part of Canterlot that was near the edge of town, away from the castle that dominated the landscape.

‘Well we probably lost a bit of weight just walking here.’ Sunset quipped. It had been a solid twenty minute trot to arrive. Sunny just smiled.

‘Well the real workout begins now. I’ve signed us up for a couple of classes.’ she said with the smile still on her face. It dropped when Sunset reacted with a frown.

‘Classes? I was hoping to have a day of easing into it just using machines. Besides, it’s still early…’ Sunset groaned. She was now seriously regretting the suggestion to join. A reassuring hoof on her back from Sunny however did buck her up.

‘Well this will be with an instructor who can tell us what to do. Following instructions is easy, right?’ Sunny said.

‘True. Alright, I’m game.’ Sunset replied, a bit more chipper.

‘Great! Let’s head inside.’

‘Good morning ladies. Ah Sunny, good to see you again. Is this the cousin you mentioned?’ the pony on reception was a chipper mare. Sunset let her and Sunny speak as she stood waiting for signing in to happen. Clearly not one who made use of the gym herself, she was sipping what looked to be one of the gyms shakes and she was on the larger side. In her mind, Sunset assumed she must have gotten a lot of comments from the trim ponies who used the gym but it was purely a guess.

‘Yes, this is Sunset Shimmer. I signed us both up yesterday for the dual membership.’ Sunny said, taking a pen in her mouth and marking down on a sign in sheet that they had arrived.

‘Perfect. The first class you signed up for begins in twenty minutes. Gives you a bit of time to prepare. Felicity, one of the founders will be leading it. Room G1.’

‘The founders lead classes?’ Sunset asked. ‘I thought they’d be buried in day to day bureaucracy.’

‘The two founders like to keep themselves involved at a lower level.’ The reception pony explained. ‘In fact I think the other class today is with Mags, so you’ll get to meet both of them. They’ve often cited it’s because they can keep up with understanding the clients better.’

‘I suppose we’re reasonably lucky they’re both here today?’ Sunny asked.

‘Yes! They rotate around the different gyms. Here in Canterlot for a spell before moving on.’ the reception pony said. ‘Are you two OK for shakes for the day? You can load up at the shake bar.’ she said, pointing a hoof over to a rather expansive bar just beyond the entry gates.

‘We’ve still got quite a few from the welcome pack.’ Sunny said.

‘Ah but the ones made here are soooo much better.’ the receptionist said, taking a big sip of hers as if to emphasise her point. ‘Trust me I know.’

‘I bet.’ Sunset said without thinking. ‘Uhhh…because you’ve been here a while right? Any tips on the best one?’ she nervously grinned, trying to save the conversation from the absent minded insult.

‘Vanilla. I’m practically addicted!’ the mare winked. ‘Anyhow mustn't keep you, enjoy your day!’ she said, going back to some administration work. Sunny and Sunset entered the gym.

As they headed to the locker room it gave Sunset an opportunity to take a look at what was going on. The gym was as Sunny had said, fairly quiet. A few ponies were around but there was plenty of free space on the equipment.

The space was extremely large and the equipment placed a fairly large distance. Just as well, clearly the current clientele she observed using it needed the space. Perhaps her judgement about the receptionist had been misplaced. The ponies in the gym were definitely bigger than her. It made her look thin by comparison. Still, it made sense they were here for sure. Sunset couldn’t help looking at one on a treadmill, flanks wider than the running belt they were trotting along. Bouncing up and down like two great mountains of jelly. The pony was wearing a hat, it had two of the shake containers in, with tubes going directly to her mouth. Two birds with one stone perhaps? Sunset decided to stop staring, it was rude.

The changing room the pair entered had plenty of lockers. Each put their bag in one, taking a key and only taking the shake container. There was no changing to be done, the class didn’t specify for any particular clothing. It gave them both a little time to head to the shake bar. Sunset didn’t see the point, but Sunny wanted to try the vanilla the receptionist had suggested.

‘I’ll pay for yours.’ Sunny said, her best effort to seal the deal.

‘Oh alright.’

It was still early so nopony else was at the shake bar. Unlike the rest of the gym goers and the receptionist, the stallion manning the bar was rather average looking.

‘What can I get the two of you?’ he asked rather bluntly. He didn’t look like he particularly enjoyed the job. He looked as if he put the most minimal effort into his appearance. The uniform he was wearing, which was by all accounts, rather smart, somewhat distracted a little from the scruffy mane and poorly kept beard.

‘Two vanilla’s please.’ Sunny said, presenting her milkshake cup. Sunset did the same.

‘Coming up.’

While the shakes were made, Sunset had another look around. It had only been about five minutes so the same ponies were using the same equipment. However a new pony had appeared at the front desk. This time, Sunny couldn’t help but stare. If anypony needed to use a gym, this mare was a prime candidate.

She had never witnessed a pony so huge. The physical form of the unicorn just about standing talking to the receptionist was quite astonishing. Her fattened hooves pressed snugly around a stomach that left no gap between her belly and the floor. This ran up to a cutie mark that was at least five times as big as normal, covering a flank that rose slightly behind a blubber packed back that must have been working overtime to keep her monstrously large behind in check. The cutie mark itself was a sphere with a purple tail. The actual tail of this pony was quite firmly wedged between the two blubbery cheeks that were wobbling even as she stood quite still. From here along that fattened back Sunny followed her body line up to a neck that was threatening to swallow her head, only held off by equally blubbery cheeks. She must have been the size of a cart. It was only the serving pony at the shake bar that made her snap back to reality, rather than Sunny this time.

‘Ladies? Four bits.’

‘Oh right, sorry.’ Sunny said, hastily going for her purse and paying for the drinks. Immediately the two turned back to look at the huge pony standing at reception. She waved a fattened hoof to the receptionist who smiled back and turned to enter the gym. Her whole body shifted quite violently with each laboured step she took. A purple jacket strained to hold back blubber. It was from this forward facing angle Sunset could make out she was wearing some gym clothing as a part of it, underwear that barely registered as visible - likely the biggest size available - struggled to make itself known between the canyon of ass that wobbled around as the pony moved. The mare stopped after a few steps, taking a look at the gym. She noticed Sunny and Sunset, waving and smiling as she had to the receptionists then turning to enter a room nearby. The door, doubly wide, was just big enough for her to squeeze through before it shut behind her.

‘Who on Equestria was that?’ Sunset asked the shake bartender.

‘One of my employers.’

‘You mean Felicity or Mags?’ Sunny queried.

‘Mags. Lovely mare. Running a class later I think. You going?’

‘Yes, we’ve got another one before though.’

‘Ah Felicity’s. Well she’s similar to Mags.’

‘Similar as in…’ Sunset didn’t want to say outright, it seemed rude.

‘Size. Look, you're new aren’t you?’ the bartender asked. ‘Go to your first class with Felicity. It’ll make sense once you’re there.’ he said. Another pony had arrived at the bar with an empty shake container. ‘Excuse me while I serve this customer.’

‘This isn’t adding up. How are all the ponies at this gym so big? Except well, him?’ Sunset said as the pair left the bar and headed to room G1.

‘We’ll probably find out in our first class. Look, a gym is a place to get in shape, that’s why we’re all here.’ Sunny replied.

‘But we’ve only seen one of the founders and she’s gigantic. Apparently the other one is pretty similar?’ Sunset responded.

‘I didn’t notice all this when I came the other day. I just signed up at reception. I glanced at the place but didn’t really look closely.’ Sunny confessed. ‘Look, we don’t have to come back after today. Let’s just do these classes and see how it goes.’

‘Fine, but honestly now my curiosity is piqued.’

-

‘Huh.’

Sunny and Sunset followed a few other ponies who had arrived to take the class. Class G1 was located just off from the main work out room. A pair of double doors swung open to reveal what looked to be a rather plain and uninspiring space. A big box of not a lot but workout mats spread varying distances apart. There was in one of the corners a shake dispensing machine, which was the only real oddity.

‘I suppose we just find a space. Here’s two.’ Sunny said, shuffling over to a couple of mats. ‘Not sure if we need much else.’

‘Oh you won’t, although have your shake cup ready!’ one of the other ponies piped up, clearly one who was a little nosy. Like the others at this gym, she was on the hefty side. Sunset thought this would be a great opportunity to question her about exactly what was going on here. She was about to open her mouth when the large double doors swung open.

‘Hello class! I’m right…nfff…damn doors, can somepony give me a pull, or PUSH if any of you are behind me!?’ the pony shouted. There was a bit of commotion as a few of the class members scrabbled forwards to grab Felicity who was attempting to enter the room. Sunset noted her physique like she had with Mags. She didn’t know pegasi could have fat wings. ‘One, two, pull!’ Felicity shouted and with a bit of effort, her enlarged rear wobbled its way around the door frame and her entire self entered the room. Sunset could get a good look at her.

In terms of size and shape, Felicity very much resembled Mags. There was maybe a few pounds in it either way which was impossible to tell but she had all the same features. A belly that rather impressively spread itself out across the floor that she occupied, a butt that arced a little bit higher than the top of her head with a tail nestled between the cheeks, a fattened neck and a rather chubby face. The only real difference as she had already noted were the chunky wings that were folded on her back, which she assumed hadn’t seen flight for some time. Felicity was blue in colour, with a rather simple red square patterned design that had stretched across those engorged flanks. She wore a couple of bands around her forehooves which looked a few shakes away from snapping off in a spectacular, cartoonish fashion. She stood for a moment, almost as if she was letting her blubber settle down from all that wobbling. The pull through the door into the room had caused all her fat to ripple like an ocean. After thirty seconds or so of what seemed like the longest time Sunset had ever spent waiting, it eventually stopped.

‘I see we have a couple of new members!’ Felicity beamed. ‘Excellent. I hope you’re ready for quite the workout.’

‘Excuse me, Felicity?’ Sunset was utterly perplexed. Every pony at this gym was fat. The two owners seemed to be the fattest of them all. She didn’t know what was going on here, but she wanted an answer. ‘Of all the ponies I’ve seen or met at this gym, except for your milkshake bartender, me and Sunny here are the thinnest. This is a gym, no? I’d have thought you might have a few more ponies with muscles, or you know, some toned bodies. And I’ll be honest, I’ve never seen a pony as big as you.’ Sunset worried about the last sentence, Sunny grimaced. It was a bit too brutally honest.

Felicity just gave a large belly laugh, one that made her stomach rock as it had when she had been pulled through the door. ‘Oh my. I take that as a compliment actually. I’ll have to tell Mags.’ she stopped laughing and just smiled. ‘I’ll answer your question, but due to my struggle with the door we’re already running this class late. Tell you what, join us with the session and at the end I’ll answer your question and anything else you want to know. Deal?’

‘Very well.’ Sunset really had no choice to agree.

‘Excellent. For those of you that are new, make sure your shakes are topped up. The rest of you know the drill by now.’ Felicity said, moving slowly and purposefully to the front of the room. There was a double wide mat there. Sunset figured she really should have guessed it was for her.

‘And sip!’

Sluuurrrpppp!

‘And stretch!’ Felicity shouted. The session was in full swing. Ponies were chugging shakes and doing some working out. It was more a session for filling your face than stretching your muscles. Felicity gingerly raised a rear hoof which only a few seconds later came down with a floor shattering thump as the full weight of it bore down on the ground. A small music box played extremely generic workout music while as instructed, ponies sipped simultaneously on their shakes. It hadn’t taken very long for everypony to empty their cups. A quick break was called for refills but after that everyone drank at varying paces. The session carried on while every few minutes a pony would take a pause to go and fill up at the machine. Most of the other ponies in the room wobbled silently. Felicity’s stomach made audible blorps! as she shifted her weight around.

Sunny could feel her body getting larger with each shake she drank. She was quite happy to go along with the class and it felt rude to not do what the instructor said. Sunset likely wouldn’t be too happy, the promise had been to get into shape, not to get even more out of it. It was definitely on her mind to not return after today. Still, she wanted to see how the class went. The shakes were rather tasty. She had actually tried a few now as the machine in here had multiple flavour dispensers. The current one was a quite nice dark chocolate drink. It was going down a treat, although definitely adding a few pounds to her figure. She could feel her hips sway just a bit more each time as Felicity provided more instructions.

‘Another sip!’

Sluuurrrpppp!

‘Lift a hoof!’ the extremely large mare said. This time she lifted one of her front hooves, gave everypony a little wave then swiftly returned it to the floor. She panted a few times before giving everypony another instruction to sip, then stopped. ‘Okay! Good class everypony. I can see quite a few of you making good progress. The new girls will need a little more time but I saw Sunny getting into it! You’re on your fifth shake!’ Felicity said with a large grin.

Sunset had purely kept at it not to let down Sunny, she too had felt quite a bit of expansion occur over the course of the class. Nothing noticeable yet, she was reasonably sure that would change quickly if they kept at it.

‘You promised me some answers.’ Sunset said as the rest of the class filed out. Felicity was left alone in the room with Sunset and Sunny.

‘I did.’ Felicity said, prodding a fattened hoof at the boombox to shut it off. ‘You came here expecting a normal gym?’

‘Well quite frankly, yes.’ Sunset replied.

‘How did you hear about us?’ Felicity asked.

‘We had a flyer.’

‘Oh, one of our new ones? That’s odd…’ Felicity said, there was a small cupboard nearby. She opened it up and pulled out a single flyer from a small stack with some effort. ‘One of these?’ she held the flyer up, it was the same as the one that had come through the door. ‘We even included one of our larger members and emphasised the shakes? See?’ Felicity said going over the flyer and scanning it with her eyes. ‘Our marketing department did all the work, perhaps it’s still not obvious enough…’

‘What isn’t obvious enough?’

‘This is a weight gain gym. Not a weight loss gym. Unique business model! Come here to fatten up!’ Felicity finally said quite honestly. ‘FATness, not fitness!’

‘Oh dear.’ Sunset simply said, she took a look at Sunny. ‘I think we’ve made a mistake.’

‘I don’t know…’ Sunny said. ‘I quite like the drinks.’

‘Oh you do?’ Felicity asked. ‘Which is your favourite?’

‘This one actually.’ Sunny said taking a sip. ‘It’s really chocolatey.’

‘What sets it off is the hint of orange.’ Felicity smiled. ‘My mum has been instrumental in our shakes. It’s her specialty really. Some of hers though are a tad too rambunctious though even for our gym! We toned them down a bit…’

‘These are toned down!?’ Sunset exclaimed. ‘I just… I can’t.’ she said. Here she was, in a room with a mare that would put any professional eater to shame and her cousin seemed to only be giving her positive feedback about the drinks! She needed a moment to stop her head from exploding. Sunny was rather good at sensing when Sunset needed some help.

‘Excuse us, thank you for the class.’ Sunny said, taking Sunset by the hoof and leading her out the room. Some space was clearly needed for the two to talk.

‘Okay!’ Felicity said. ‘Oh…everypony left. Well let’s just hope I don’t get stuck…again…’

Sunset and Sunny were too far away to hear Felicity shouting for staff to give her another pull through the doors.

-

‘Look, I know this isn’t exactly what we signed up for…’ Sunny started to say.

‘Isn’t what we signed up for? Did you even ask the receptionist when you came here what this “gym” was about?’ Sunset asked her, cutting her off mid sentence.

‘Well no! I saw a gym and lots of equipment. It looked normal.’ Sunny said with a slight moan. ‘How was I to know it was a gym for getting bigger! The flyer wasn’t exactly helpful either, although looking at it more closely with Felicity it made sense after she explained it. Their marketing department isn’t very good…’ Sunny sighed. ‘We can leave if you want.’

Sunset was about to, but then she decided she wanted to question Sunny a bit. The comments about the shakes were one thing, she seemed really into the session as well. An eyebrow went up. ‘You seem to be enjoying yourself.’

‘A-Am not!’ Sunny retorted. It was very obviously a snap response. The stutter was key.

‘You were sipping those shakes like everypony else and you put your back into slurping them down, perhaps not so much the exercise portion however. You were asking Felicity about the shakes.’

‘I was curious.’ Sunny said flatly. ‘Well, perhaps. I mean it is good fun. It’s not what I expected at all.’

Sunset was all for going to her locker, packing up her stuff and leaving, never to return. But then the bottom lip on Sunny trembled slightly. She knew that reaction. It was one of regret, but also hesitance. ‘You want to do the next class with Mags, don’t you?’

‘I just think it would be rude to leave early is all.’ Sunny said. She still wasn’t quite ready to admit to Sunset her true thoughts.

‘Let’s do the next class. It would be rude.’ Sunset said. Sunny smiled and the pair went to reception to ask where it was taking place.

The room was equally large. Instead of mats however, a number of large yoga balls were stored in a corner, again with one of the milkshake machines. As regular ponies entered they each grabbed a ball. Sunny and Sunset followed suit. With the size of some of the patrons, Sunset wondered how the balls didn’t simply explode as soon as any weight was put on them. Reinforced or filled with something other than air, maybe? She tapped her ball a few times. It felt normal.

The class was due to begin in a few minutes. Like Felicity, the double wide doors were just slightly too small for the mare to fit through without becoming jammed. Mags however, seemed to slip through unhindered. It was then that Sunset spied a bit of yellow on her enormous flanks. Butter, she assumed pre-applied. Mags seemed a bit more prepared for the eventuality of getting stuck due to her size.

‘Before we begin.’ she said. ‘The next session will take place in room G5, as we’ll be starting to retrofit all the rooms with triple wide doors, so some will be out of action for a while.’ the announcement made Sunset grin. Mags didn’t seem to take notice of the two new ponies. Like Felicity she informed everyone to make sure that their shake cups were filled and the session would begin.

What followed was quite the experience. The balls did indeed hold up. It wasn’t the filling, it was the material they were made from. While it felt the same as a standard exercise ball, the whole thing could be nearly flattened without popping. It would then return to its original shape. Mags instructed the class to do a number of moves around the ball, with each one having a short break if anypony needed a refill. Fattened legs went up and down, stomachs smooshed balls. The highlight was near the end when Mags instructed everypony to flex their flanks by placing the ball like a seat at their rears and then rocking back and forth on it. Sunny and Sunset quickly lost sight of Mag’s ball, her gigantic rear practically swallowed it up. She seemed completely unphased as everypony else followed along, still drinking their shakes. When she was done, the ball reappeared back in its original form. After a few more exercises to cool off, class was dismissed.

‘Remember, different room next session!’ Mags bellowed as everypony filed out. Sunset didn’t feel the need to find a private spot for the conversation. Sunny once more had seemingly been quite into the class. Nopony appeared interested in what they were talking about anyhow.

‘So that was different.’

‘Yeah, the ball was very sturdy.’ Sunny replied. She was mid sip of a shake. ‘Do you still want to leave?’

‘That depends.’ Sunset said. ‘What do you want to do?’

Sunny put a hoof to her chin. ‘You know you can’t tease me if we’re both big.’ she said, half joking. ‘We could always slim down, right? What if we tried it?’

‘I’m only half convinced, the half that I am coming from you. I mean, what advantage is there to being big?’

‘Oh lots.’ Mags said. ‘Sorry, I was listening. How you feel for one thing, I’ve never felt as good as I do now, and every time I get bigger I feel even better.’ she explained. ‘Plus ponies give you a bit of preferential treatment. Stares, plenty of compliments. If you like being the centre of attention anyway. I think the only downside is the food and clothes bill.’ she laughed. ‘And looking behind you. All I see these days is my cutie mark.’

‘Well, I do like being the centre of attention.’ Sunset said. It was vain to admit it, but Sunset always had. In Equestria nopony really knew her, some even avoided her after hearing the stories. Perhaps if ponies approached her it would give her a chance to explain, make things better? She didn’t really know in all honesty.

‘She would say that.’ Sunny rolled her eyes. ‘I’ve always kind of wanted to see what it felt like…’ Sunny admitted. ‘How long did it take you to get so big, Mags?’ she asked.

‘Oh this is the product of quite some time of drinking our shakes. As well as a bit of food overindulgence. Maybe a year?’ she said. ‘Although I’m sure if you were committed you could do it faster. I was a bit casual.’ she scratched her head. ‘At least I feel like I was…twenty shakes a day probably doesn’t count as that.’ there was an awkward smile.

‘Can we try Sunset? We can always slim down I suppose if it doesn’t work out.’ Sunny said. The lip went again, that little pouty quiver was hard to refuse.

‘Oh, alright.’ Sunset tried making a show of trying to seem like she wasn’t happy about it. She was somewhere in the middle in all honesty. She still felt a lot of uncertainty around it all, but at least with Sunny she wouldn’t do it alone. Besides, being the centre of attention again would be a nice little ego boost, even if it was different to what they had planned.

‘Great, well I’ll be seeing you two until me and Felicity move to the next gym. I’m glad you stuck around actually.’

‘Why’s that?’ Sunny asked. Mags presented a small tub of butter.

‘Do you mind? Otherwise I’ll never get out of this room.’ she grinned. Sunny took the butter.

-

‘Pass me a shake.’

Magically, Sunset topped Sunny’s shake up at one of the nearby machines. Her and Sunny had now been attending the gym for around a month. Mags and Felicity had moved on to another branch some weeks ago so were no longer present. Not much had changed though, just the class instructors weren’t quite so huge as the pair of them.

‘Do you think if I get back enough, they’ll let me run a class?’ Sunny asked Sunset.

‘You’ve got a bit of a way to go.’ was the reply. It was true. Since the weight gain journey, Sunny had taken the task in her stride. Sunset had still needed a bit of convincing, but she was gradually getting there. Sunny thought back to that tease prior to joining the gym, it had stuck in her mind. Now the question of “Hey, are you gonna eat that?” was usually one that got a yes as a response. No longer a subtle insult.

The pair had bulked up nicely. They still, as Sunset had said, had a ways to go. Sunny was the bigger one, compared to Felicity she was about just over half her size. The changes to her body had been quite dramatic but Sunny could see her figure forming up nicely. Her flanks over the previous weeks had ballooned, her stomach had swelled in size and her wings were now firmly folded on her back all day long. She had last tried to fly a few days back, about hovering off the ground for a mere few seconds before she had given up with her frenzied flapping trying to lift herself up. It was the only real downside, being grounded. Still, Sunset’s magic made everything easier.

Today there were no classes, the pair had decided to see how they could use the machines to increase their gaining. Sunny had spoken to the receptionist, who had tried to explain it as best she could.

‘But wouldn’t using the treadmill make you lose weight? Seeing as you’re doing exercise?’ Sunny had asked.

‘Normally yes.’ the receptionist had responded. ‘But the machines here are all calibrated for maximum gaining. You can’t set the treadmills above a slow trot, for example. You won’t burn much off.’

‘Weights?’ Sunny had then asked.

‘Weigh nothing.’ had come the response. ‘The idea is with everything you’re moving around, doing something to feel as if you’re burning calories but in reality you’re not. So you’ll work up an appetite without really putting a lot of effort into doing so.’

‘Huh.’

‘That probably explains your confusion from when you joined? Don’t worry, Felicity told me. We really do need to make it more clear…’

So right now, Sunny and Sunset were very casually trotting along on a treadmill. It seemed to be working though, Sunny felt herself wanting something to drink quite frequently, but was she losing any pounds? Highly unlikely. In fact when they had finished, she felt her flanks brush the ground as they wobbled about behind her head.

‘You’re getting huge.’ Sunset commented. ‘That thing will be permanently grounded soon. Might want to arch your back up a bit.’

‘Maybe.’ Sunny said, taking a sip of her shake. ‘You think in a few months we’ll be matching the owners for size?’

‘Matching?’ Sunset paused for a moment, thinking. ‘Bigger than.’

‘B-Bigger?’ Sunny felt her cheeks go a rosy red. ‘I dunno, they were both barely even able to move about themselves. I’d still like to be able to get around under my own steam.’

‘Just with a lot of struggling I imagine, you’ll have to pack butter with you wherever you go. Heck I might have to as well.’ Sunset grinned. ‘You’re already struggling to get through the front door of our house.’

‘But you’re there to give me a push.’

‘Yeah but what about when you’re so wide you’re double the width of the door Sunny, what then huh?’ Sunset retorted.

‘I think after this we better go see the local carpenter.’ Sunny said. ‘You know, just in case.’

‘For a double wide door?’ Sunset asked.

‘Probably need to go wider, if I’m going to be bigger than Mags and Felicity.’

‘The front of your house is just going to be nothing but door, isn’t it?’ Sunset rolled her eyes.

‘Please.’ Sunny laughed. She stepped off the treadmill and pointed a hoof over to a large empty space in the gym. It was squared off from other areas by roughly neck high walls and a few yoga balls were dotted around the edge for anypony to use. ‘Come on, don’t you wanna try the balls?’

With a slightly larger rear than Sunset, Sunny sat herself on top of one of the inflatable balls, positioning her butt right on top of the ball as she let it take the weight of her entire body. The ball contorted slightly, she felt it nestle right between her cheeks as she bore down on it. She tried not to look too into it as she took a sip of her shake. Sunset found her own, instead opting to try to flatten it with her stomach. Sunny giggled as she watched her. She wasn’t very successful.

‘You’ll have to gain a few more pounds.’ she quipped as the ball pinged out from under Sunset and harmlessly bounced into one of the walls.

‘Mags made it look so easy.’

‘She probably weighed twice as much as you.’

‘Pah.’ Sunset sneered. ‘That sounds like a challenge.’

‘More stating facts.’ Sunny smiled. ‘This feels…nice.’ she rolled the ball around under her rear, the thing seemed to be caressing fat in a way that she had never felt before. More weight would probably make it feel even better, perhaps a few more balls, or one gigantic one… her mind started to wander as she rocked around on the yoga ball. She was so lost in thought she barely noticed that she had finished her drink. Only the sucking sound of the empty cup running dry caused her to snap out of her daydream. ‘Oh, can you get me some more?’ she asked Sunset, who had given up with the ball.

‘Alright, just don’t get too carried away. You don’t have that triple wide door yet.’ Sunset commented. She vanished for a moment to find the nearest dispenser.

Sunny on her own continued to roll the ball around under her. She thought about what the future might look like, or rather perhaps more aptly, how she might look in the future. She hadn’t told Sunset that looking at Mags and Felicity had captivated her, she wanted that figure for herself. One that screamed confidence and told everypony else you were there and to take note. You were simply unignorable. Already she had started to notice other ponies made comments and she got the odd look, but she still had work to do to get that jaw drop reaction she had when she first laid eyes on Felicity and then later Mags. The bigger she got, the better she felt. There was little to it. So easy, yet something her and Sunset were going to have to work at.

It wouldn’t be cheap either. The gym membership, alongside the required amount of shakes. Sunny had tried supplementing them with large amounts of fattening food at home, but it just wasn’t the same. You had to eat far more and felt fuller far quicker than you did by just drinking the miracle shakes you got from the gym. Sunny had tried reading the ingredients once. It was a lot of things she didn’t recognise. The only thing she really got was they all listed far higher daily intakes than was recommended, just in one shake. Drinking multiple? Well the results spoke for themselves.

Her mind continued to wander. The purchasing of extra sturdy and bigger furniture perhaps? She was starting to consider having the stairs in the house reinforced when her thoughts were interrupted by a ‘Here.’ Sunset had returned. ‘You were thinking, weren’t you?’

‘About a lot of things.’ Sunny replied.

‘I could tell. Don’t let it all overwhelm you.’ she passed her the shake. ‘For now just focus on this.’

Sunny took it and had a large sip. Suddenly the world seemed much more simple. Just drink and gain. Drink and gain. The three words stuck in her head. She rolled herself forward, getting off the yoga ball. It gently returned to its original shape and Sunny relaxed.

‘Weights?’ she asked Sunset.

‘Sure.’

-

Sunny felt the bed creak under her. It had been moved several weeks ago to a room downstairs. The upper floor in her house had pretty much become a no-go zone by this point. She had stopped being able to fit up the staircase some weeks ago. Prior to that, the floors had begun to bow and buckle under trying to keep up with the massive weight of the two mares. She and Sunset had finally started to stop trying to fight gravity. The shuffling around of furniture had been laborious, but needed.

Both of them were quite excited, it had now been about half a year since they had begun their journey. The reason for the excitement was during their last visit to Uplift, the receptionist mentioned Mags and Felicity were returning today to do their part in the classes once more, as they had rotated around all the other gyms and were returning to Canterlot. Sunny was looking to impress the pair of them, hopefully to the point where this time, their jaws would drop when they saw her and Sunset.

Her memory was a little fuzzy on just how big Mags and Felicity were, but there was one thing Sunny was certain of.

She was bigger.

The mattress, one of several Sunny had to stack on top of each other due to her immense weight crushing them all down to thin wedge when she lay on top of them, seemed to almost breathe a sigh of relief when she got up off them. She yawned, scratching her head and instinctively reaching for a shake. She had a half one left from her nightstand which she gulped down. Sunny turned, feeling her bulbous rear brush against several pieces of furniture as she did so. Despite having all the doors of the house widened considerably, she felt her stomach and butt easily ride up against the frames on both sides as she moved herself slowly into the living room. Sunset wasn’t up yet. While Sunny waited, she made herself a new shake. It was the only thing their fridge now contained. The pair spent roughly an hour each week making enough to last the week, they usually rewarded themselves by consuming several of them right there and then.

Groooooooooaaaannn!

That was the other thing, it had started some weeks ago once Sunny had surpassed the size of Felicity. Her stomach would periodically almost moan like a small child to be fed by making various noises. It rumbled beneath her, a reminder of just how vast it had become. Her hooves barely at maximum spread stretched around the fat and made contact with the ground. Those comments of immobility were rapidly approaching.

‘Morning.’ Sunset said, yawning herself and magically grabbing a shake out the fridge. The pair stood silently slurping for a moment at the fridge, Sunny felt her stomach calm down for a moment as it was satiated by the shake. ‘Your stomach woke me up, again.’ Sunset commented.

‘Well it’s not like yours is exactly silent.’ Sunny replied. ‘It just needs more shakes.’

‘Touche.’ Sunset said. ‘So today is the day they return isn’t it.’

‘Mmmm.’ Sunny said, she pretended not to care, but inside she was quite literally buzzing with excitement. They’d need to leave early, although the gym was reasonably close, getting there now took thrice as long as it did, due to the slow and laboured movement of the pair. Sunny grabbed a giant saddle bag, filling it with shakes to take to the gym. ‘Shall we get going soon?’

‘You better go first, just wait for me outside.’ Sunset said. Sunny nodded, moving forward and squeezing her way out the triple wide doors. The slow waddle there would give her time to think on just what she’d be saying to the owners.

Everypony had watched as the two lardy mares had gone by, quite a few times Sunny felt her massive flanks brush up against Sunset, blubber coming together for a few moments until one of them took a step forward and they parted again. The feeling was rather nice, Sunny dared not admit to Sunset that she was starting to do it on purpose. The occasional ‘Whoops!’ as she felt them come together was enough to keep her from cottoning on. Eventually after some time, they made it to the gym. Sunny had been a bit distracted by the whole ordeal, but she had a good idea of what she wanted to talk to Felicity and Mags about. Like before, each one was doing a class that both Sunny and Sunset had booked themselves onto.

‘Room G1. The doors are triple wide now, but…’ the receptionist said, trying to look around Sunny. She had to take several steps to the side just to get a view around that monstrous flank. ‘You’re going to struggle to get in.’

‘I know.’ Sunny said, her smile quite wide to show she was pleased by the comment. ‘Let’s go, we don’t want to be late.’

Felicity observed the class. A slightly different mix of ponies than last time. They all looked quite eager to begin. Two more were booked on that hadn’t appeared yet as she looked at her register. She thought she better give it another minute or two.

‘We’ll begin as soon as everypony is here, while we wait, fill up your…’ she looked at her milkshake bottle. The liquid inside it was moving. It was on the floor. Every few seconds there was a gentle thump and the shake moved. Eventually it tipped over as the thumping got louder. ‘Can everypony else hear that? Or feel it?’ she asked. Several heads nodded. Felicity by instinct went to the door and opened it, what greeted her on the other side was the last thing she was expecting to see today.

A white pony stood in the hallway, a second just behind her. Felicity’s mouth dropped for a second, then she just stared. This was clearly the two ponies booked onto the class, she recognised them from her previous visit. However last time they weren’t so…big. Sunny was double Felicity’s width, her flanks rose a good four or five feet higher behind her head and her head was so nestled in a ring of fat it was quite obvious her fattened face was fighting to not be swallowed up by it. The pony simply grinned, stretching a fattened hoof to bring a shake bottle to her mouth. The entire thing was devoured in seconds. What followed was a loud and noticeable glooooorrrrpppp! as her satisfied stomach sang a tune of fulfilment. It wouldn’t last long. ‘Good to see you again Felicity.’ Sunny said. ‘Sorry, we’re a little late.’

‘N-No problem.’ Felicity replied. She moved herself back a few steps. ‘Come on in, we were just waiting for you.’

‘Great, let me just…’ Sunny said, stepping forward to enter the room. The entryway, although widened considerably since the last time Sunny had been in the class with Felicity, was just not wide enough. Sunny made it halfway through before she felt her bulbous rear wedge itself firmly into the doorframe. This time, it was Felicity who was pulling Sunny free as her and a few class members took her by the hooves and began to pull to try to get her through. Behind her, Sunny felt Sunset lean her own weighty body into hers to give as much pushing power as possible. There were a few heave-ho’s before Sunny eventually through some wiggling and jiggling managed to slide herself inside the room. She panted, standing up and feeling her blubbery butt press into the ceiling. The room was large, but Sunny took up a good quarter of it just on her own. Sunset didn’t quite run into the same problem, she was a little smaller than Sunny, only a couple of the class members had to assist with pulling her in. Both of them filled up the back half of the room easily, squashing the rest and Felicity towards the front as the mare nervously looked at the pair of massive ponies practically looming over her.

‘Okay, let’s begin.’ Felicity simply said, with the routine starting. Her mind was swimming and switched to auto pilot for the class as she gave instructions and sipped her own shake. These two must have really gone to town on the shakes to get so big so quickly. She remembered the conversation she had with them the last time they were here. The slightly smaller one in particular had almost been in shock when she found out it was a weight gain gym. Now here they both were, by the far the biggest ponies she had set eyes on. Her and Mags some time ago had hit a size they were both happy with and for practicality’s sake, hadn’t pushed their gaining much further. These two however clearly had no such qualms. She remembered as well last time the confusion over the purpose of the gym as well. As she stretched a leg and watched Sunny copy her, she had a thought forming in her mind. She’d need to get Mag’s input, she’d try to keep the two of them here when they were done and explain her thinking. Felicity brought her leg down, she watched as Sunny did the same, with a lot less finesse. The entire floor shook as the fattened hoof of Sunny hit the laminate. A few cracks appeared under it, Felicity decided to limit the workout to gentle movements so the entire room wasn’t ripped apart by the two elephants at the back, huffing and puffing their way through the extremely gentle routine.

Eventually the two of them were quite content to just take advantage of the free shakes offered along with the class. During a break session, Felicity asked one of the students to find Mags and ask her to come along at the end of the class. She a proposition for these two, but Mags needed to be on board.

‘You wanted to see…’ Mags waddled her way into the room. Felicity was in the middle of talking to Sunny. Mags had almost the same reaction as Felicity, she was silenced as she took in the quite impressive sight of Sunny and Sunset. She had to tilt her head up slightly to get a full view of the two in totality. Her eyes went up to the ceiling. As Sunny spoke, her whole body moved, unable to stay still even when she was in essence, quite still standing in place. Two peaks of jelly wobbled and brushed the ceiling as they did so. If Mags was the size of a cart, this pony was the size of several carts, all extra large ones. Mags coughed. ‘You wanted to see me?’

‘Hey! You remember Diamond Sun and Sunset Shimmer, right?’

Mags had a think for a second, but it did come to her. ‘Oh, from the last time we were here? You two have really…’ she stopped herself, she didn’t want to appear rude.

‘Grown immensely?’ Sunny said with a smile. ‘Gotten massive?’

‘Two ways of putting it.’ Mags replied. ‘I can see why Felicity wanted to see me. Or rather, see you.’

‘I must say it’s something I wasn’t sure about.’ Sunny replied quite truthfully. ‘Sunset even more so, the gaining I mean.’

‘Mmmm.’ Sunset simply replied, for now she was happy to let Sunny speak.

‘But I’m enjoying it, a lot.’ Sunny said quite proudly. ‘Actually, I want to keep going.’

It was at this point Felicity waved a hoof, beckoning Mags closer to the conversation. The four ponies on their own nearly filled the large classroom, Sunny and Sunset doing most of the filling. There wasn’t much room to manoeuvre.

‘Like we’ve clearly inspired you. You inspired me.’ Felicity started to say. ‘I was quite distracted during that whole session.’

‘You were staring quite a bit.’ Sunny responded. ‘Most ponies do these days.’

‘Indeed, but I was thinking as well as observing. I have a proposition. Mags I want to see if you’re on board.’

‘Oh this should be good.’ Mags said, rolling her eyes. ‘What are you thinking Feli?’

‘I remember how the two of you were confused after the first class. We have a clarity issue here at Uplift. You’re not the only ponies who had no idea what this place was really about. It’s caused us problems, negative press and the like. We’ve been thinking about ways to rectify the issue. I think we’ve found it, well, found them.’ Felicity explained. ‘How would you two like to be spokesponies for the gym? Feature on our ads? If other ponies see the sheer size of you both, hear your own stories about your journey to become the fattest ponies in Equestria - there would be no confusion anymore. Extoll the virtues of being big, tell everypony how great it is. We’ll pay you a salary, free shakes whenever you want, transport to all the events…’ Felicity stopped herself. ‘Ahem, if you think it's a good idea, Mags?’

‘I think it's a rather simple solution. If they’re happy to do it?’ Mags said. ‘I mean, ponies definitely won’t be confused knowing what we’re all about once they set eyes on you two.’

‘A moment.’ Sunset said, she motioned to Sunny - all they could really do was turn away to discuss it in private. Before Mags and Felicity, two gigantic rears filled the space in front of them.

‘Celestia that’s…’

‘A flank size you aspire to?’ Felicity said, teasing.

‘Shut up.’ Mags blushed.

‘Is this a good idea?’ Sunset started to say. ‘I mean, she’s practically saying everything we want to hear. Or at least, if we’re committed to this. I take it slimming down is off the cards now.’ Sunset said.

‘We get paid, we get free shakes and free transport. If they can throw in somewhere bigger to live I don’t see why we shouldn’t. We’re practically living at this gym anyway.’ Sunny said. ‘I know this wasn’t something you were originally sure about but be honest…’ she gave Sunset a little prod, watching her fat jiggle. ‘You like it as much as me, don’t you?’

‘P-Please, I do…’ Sunny put one of her chubby hooves up to Sunset’s mouth, smiling.

‘You can stop there, the blush and stammer is enough of a giveaway.’ she giggled. ‘Besides, don’t think I haven’t seen you on the yoga balls the past few weeks when we’ve been here. Poor things, you really go to town on them.’

‘I uh…’ Sunset didn’t have any defence. ‘...get the house and I’m in.’

The pair turned back, Felicity and Mags were still standing there. Mags cheeks were a good shake redder than when they had turned away, Sunny couldn’t imagine why.

‘So a salary we’ll discuss, free shakes, free transport. Provisionally it’s a deal if…’ Sunny trailed off.

‘If?’ Felicity asked.

‘Our current house is a little on the small side now, if you can throw in a house we’ll do it.’

‘Oh, we can offer something better.’ Mags said with a smile. ‘How about you live here at the gym?’

‘Live here?’ Sunset asked.

‘Well it makes sense, doesn’t it?’ Felicity said. ‘All the space you could ever need, at least within reason. Okay, some of the doors are a little small for you. We can fix that. We can convert part of it, or half of it, or build an extra wing. But if you’re going to work here, might as well, no? You could access our milkshake dispensers in the middle of the night if you wanted.’ Felicity was clearly trying to sweeten the deal, it was already sweet enough for Sunny. At this point, Sunny just looked at Sunset who nodded.

‘Deal. But before we sign on the dotted line, let’s discuss that salary…’ Sunny said, smiling. The four of them made for the exit, with Sunny stopping before she got to the door.

‘Something wrong?’ Mags asked.

‘Yeah…got any butter?’ Sunny said with a grin. She motioned one of her hooves at the door, then it dawned on Mags.

‘Always.’ the mare said, producing a jar of it from her jacket. Sunny laughed, the tables had turned.

-

Sunny stomach rumbled. It never stopped rumbling these days.

Grooooooaaaaannnnnnnnn!

‘Shhh, breakfast will be soon.’

‘Hmmm?’ Sunset, nearby, was waking up. It was morning, reasonably late in it. ‘Breakfast? I could go for breakfast.’

Since taking on the job a year and a half ago, Sunny and Sunset had continued to balloon in size. The shakes hadn’t stopped coming. The gym, as promised, had gotten a portion of it converted to what would be considered an extremely large house, verging on a mansion. Six months in, they had to remove the second floor to make way for the ever expanding duo. It had probably been a bit shortsighted to put one in in the first place. Eventually it had become one large ground floor. When the ultra wide doors were no longer wide enough, they had removed entire walls. No furniture could support them any longer, what was left was mostly for visitors or decoration. Sunny and Sunset exclusively slept on large, comfortable mats on the floor, replaced weekly due to their immense weights flattening them wholly within a short time span. Everything else was taken care of for them, Sunny had managed to include a few full time staff members to tend to them in the contract. Right now as they woke up, she could see one of them preparing breakfast, which would consist of a large number of shakes. She searched her brain for a schedule. Today they were doing some meet and greets, then an appearance at the gym to encourage any patrons. Pretty standard stuff.

She observed Sunset, who had caught up eventually and both of them were now pretty comparable in size. Neither really outclassed one another, but they certainly did outclass every pony in the world for size. None compared. Sunny looked at Sunset. Flanks several stories tall, her hooves didn’t even touch the floor anymore. They hadn’t for a long time - movement was no longer a concern. Once the pair no longer could move they were hauled around on carts. Once those gave up it was magical teleportation. Finally, when even the best unicorns struggled to teleport such a mass they had simply been placed in the house in the gym where it had been modified. The front pulled away to reveal the two at their request. Ponies came to them. They were fed, pampered and paid well. Sunny and Sunset had kept up their end of the bargain, they promoted uplift.

It seemed to work, a number of patrons had matched the sizes of Mags and Felicity, at least to what they were back when they enlisted the duo. Everypony had grown since then.

Sunny felt her own mountainous rear wobble as she shifted her weight slightly. Each mare in totality was the size of a small house. Sunny these days as well as struggling to move did struggle to see much beyond what was in front of her. Her head was slowly being consumed by fat rolls, as well as the rest of her limbs. Movement was a distant memory at this point, replaced by the warm feeling of being surrounded by her own voluptuous body. Their stomachs never stopped wobbling, their flanks never stopped growing and bwoomphing. It was bliss. The feeling utterly indescribable, Sunny thought she’d never stop growing. She couldn’t see an end in sight.

What was in sight however, was breakfast. A few more pounds to add to an endless blobby sea of mare. She opened her mouth, seconds later, she was greedily sucking down a delicious shake.
