“Hello? Starlight?”
Trixie’s voice almost echoed in the main hall as she peaked her head round the front door of the crystal castle, she had been knocking for a good five minutes and finally gotten bored. A gentle push with her hoof revealed that it was already open and her face had contorted to a mixture of disappointment and anger as she watched it swing open before her. Usually somepony answered, or often nopony. Spike usually greeted her on the rare occasions she did actually visit.
“Okay, this is freaking me out just a teensy bit. Is anypony home?”
More echoes and no reply from anywhere. Trixie’s horn started to glow the faintest shade of pink, almost wispy in appearance as she trotted forward, half expecting something to leap out at her from one of the many, many labyrinth style passageways that dotted her path as she walked onwards.
There was a smell however, Trixie stopped and sniffed the air, taking in long deep snorts up her nostrils. It smelled, well it smelled delicious. She decided instead to follow her nose and see what she could find with that rather than trotting around some empty castle where nopony replied to her calls. She almost harrumphed in annoyance, carrying on down various corridors and passageways continuing to follow her nose.
Further and further in she carried on. She wasn’t quite sure she remembered the castle being this well...hard to navigate. She felt like she had been following her nostrils now for quite a while. The smell was extremely strong, and she stood before a closed doorway, one easily recognisable. She had been here a few times before, although it often wasn’t shut. A grand entrance perhaps with a small puff of smoke should coax out anypony inside, although she was mostly sure who was in there. She abruptly opened the door with her hind quarters sending it crashing open.
“STARLIGHT!”
The door slammed into the wall as it flung open, and as she thought a small puff of pink smoke announced her entrance. Small pinwheels of magic-infused sparkles completed the whole show as Trixie grinned to find her friend…
... Wide eyed, screaming and her face covered in cake batter as she practically jumped backwards away from the mixing bowl that she had been so focused on before Trixie had burst into the room.
“Aieeeeee! Trixie!” Starlight’s scream made the blue mare’s ears twitch as they were assaulted by a high pitch ring. She wondered if perhaps the entrance had been a little...too grand.
Starlight looked up and rubbed her now batter-covered face trying to clean most of it off. “Really, you had to come in like that!?” She yelled, still clearly annoyed.
“Of course! I can’t be great and powerful if I don’t make a grand entrance from time to time! Perhaps too much though? Heh…” She grinned once more and trotted into the room. “Where is everypony anyway? The door was left open and not even Spike answered when I knocked, for a whole five minutes.” Trixie frowned, trying to get her disappointment across to her friend. “I mean honestly, how can you be a princess and run a castle when nopony even answers the door? What if you get somepony with an emergency? Don’t even get me started on the fact that the door was unlocked.”
Starlight looked a little perturbed, but decided to answer regardless. “Well, Twilight and Spike are away on official duties and I’m the only one here. Nopony comes to me looking for friendship advice so I decided to try to get a little better at...baking.” She smiled at Trixie and leaned down to one of the many ovens that were dotted around the room, opening the door and pulling out an unfrosted cake by levitating it out the oven and onto the counter. “I know one of my friendship lessons a while ago was bake a cake with Pinkie but I wasn’t very good at it, I thought it might be nice to actually try to be good at it the next time we bake. I think we can both recall how the teacakes went last time around…” She raised an eyebrow and gave Trixie a rather sharp look.
“So how's it going then, is this the first cake?” Trixie eyed the unfrosted slab that sat on the counter rather suspiciously as Starlight started to set to work trying to apply some sort of decoration and sweet topping.
“Um...not exactly.”
“What do you mean not exactly?” Another concerned eyebrow raise, this time from Trixie.
Starlight nervously pointed over to the door Trixie had come through, although a great kitchen it was rather small and both of them trotted out down the hall slightly to an adjacent room. With a glow of her horn Starlight opened the door and each of them entered.
“I see why not exactly was the favoured term…” Trixie said, looking around. The room was mostly bare of furniture, clearly a storage room and extremely large in size with only the walls really to show for anything, the obvious thing, or rather things sat piled high that left very little room the maneuver which was an absolutely comical amount of well...cakes.
Trixie sighed. “Why, why in Equestria is there so many?”
“Well it wasn’t going so well, I didn’t want to just throw the cakes away! So the first few I put in here, I thought I could keep them for a little while until Pinkie came and perhaps she could use them. But then Twilight’s trip got extended and I thought I’d keep trying. I might have gone a tad overboard.” Starlight squeaked the last few words in embarrassment.
“What was the plan, just keep on filling this room with cakes then?” Trixie smirked.
“Obviously not, I got better as I did more! The ones closest to the front are pretty good actually.” Starlight took a slice of one of the cakes and levitated it over towards Trixie, planting it on her waiting hoof. “Try it, I’d like to know.”
The blue mare decided to sniff it first, clearly these were contributing to what her nose had found earlier, a mound of cakes this big was making the whole room smell like Sugarcube Corner on a rush day. Her nostrils crinkled as she took a deep draw, it didn’t smell too bad. A bite was next, putting it in her mouth she saw Starlight eagerly awaiting a reaction.
“Well, it’s not too bad, but you clearly need practice.” She put it to her friend bluntly. “And now I need to know what you plan to do with this mountain of food. It can’t stay here, Twilight’s head might explode if she comes back and finds a room full of cakes that has suddenly appeared in her absence.”
“Urg I know, on both counts. Poor baking and preeeeety poor planning on what to do with the cakes…” Starlight sighed, clearly there was no plan on what to do with them forthcoming. “I mean what do you suggest I do with all this food?”
“Well I know the Ponyville orphanage would be very pleased with a donation of this size.” Trixie began to rattle off ideas on what could be done with such a mountain. As she did though her stomach growled, it had been a little while since she had eaten herself. Her cheeks went a light pink and she smiled at Starlight. “Or perhaps I could have a few more slices? It wasn’t so bad and it seems silly to waste food directly in front of you.”
Starlight grinned, picking up a cake from the pile with her hoof instead this time and waving it around gently to get the Trixie’s undivided attention. “Well come a little bit closer, if you want more it’s going to be much easier if you’re closer to the mountain.”
“It’s the mountain now is it?”
“I don’t think we can call it anything but.” Starlight giggled as Trixie came closer to her, eyes fixed on the cake.
Trixie thought one slice was coming her way, but as she came level with Starlight she too late recognised that mischievous grin that her friend often sported when she was in a troublesome mood. She opened her mouth to find not one slice, but the entire cake being pushed down her throat as she spluttered and gagged, unprepared for the onslaught of creamy delight that was bulging her cheeks out as she struggled to chew. After what seemed like an eternity of awkward chews and rolling the cake around in her mouth she finally managed to swallow the last few crumbs. “H-hey! What’s the big idea?” Was all that she managed to say before the next cake was quickly forced into her maw as she spoke, Starlight wasting no time in pushing the next one down.
“Big idea? I don’t think I had a big idea for the cakes, although I might have two big ideas.” She laughed a little as she watched Trixie consume the second cake, a little faster this time. She seemed to be getting used to quickly having her mouth filled with the treats. “I don’t think it’s quite fair to make you eat all this, I think the two of us could manage it much more efficiently and get through this mountain before Twilight comes home. Not the best treats but it should make for some interesting eating…” Starlight trailed off as she stopped passing Trixie cakes and began to levitate them towards her mouth instead, using her own hooves to start to feed herself.
“Sorry it’s such a varying degree.” Starlight continued as she watched a number of her home-made goodies levitate towards Trixie’s mouth, the poor mare unable to stop the onslaught of cakes being fed to her, as soon as she finished one another was lined up waiting for her. “But I was practicing, at least you can guarantee that they’ll each be as calorie-rich as each other I suppose!”
The growth was slow at first, Trixie was hungry so her body was digesting the cakes rather well, a little to Starlight’s disappointment. But quickly she was full, and her stomach was doing its best to keep up with the unusually large proportion of intake, and failing rather rapidly. Her middle began to gain just a little bulge at first, but with each cake it was gaining size. A bulge was starting to appear that made Starlight smile, who stopped her own eating to compare it with one that she was nursing along. “Not bad, for such a short amount of eating. I’m expecting it to be a big more hefty than that when we’re done.” She cooed, coming closer to Trixie and keeping her mouth firmly full of cake the entire time. Not once stopping to give the poor mare any reprieve. She gently pushed her tum against Trixie and felt the warmth of her belly against her as they touched, only driving Starlight on who returned to the cake pile and continued to eat.
A small lapse in Starlight’s judgement allowed Trixie a few seconds to speak, managing to eke out “Why?!” Before yet another cake was pushed magically into her maw and more chewing ensued.
Starlight laughed, in that way she does when she’s starting to lose her senses just a little bit. “Why? Well why not? I’ve got no better plans for these cakes. Give them away? Please. Nopony would take them. Teleport them? Where can I move a whole room of cakes that wouldn’t get noticed? Destroy them? Such a waste! Besides Trixie you could stand to gain a few hundred pounds.” She said, before putting another cake into her own mouth and chewing on it as quickly as she could to get out her next sentence. “Besides, I think you’ll come to like it the more you eat. It quickly grows on you.” She smirked, looking at the growing mass around Trixie’s middle.
It suddenly became very clear to Trixie why there was a room full of cakes, in fact there might always have some sort of sweet treat locked away in here that took Starlights fancy. The castle was so big it must be easy to find a room that hardly gets touched or looked into where things can be...kept. Trixie’s mind started to wander as to what else Starlight could, and probably did keep in here and how often she managed to sneak in. A few times in the past she had turned down an invitations of Trixie’s for Castle Business. She always wondered what it meant, now she knew.
Her meanderings in her mind stopped and she focused back on her feeder. Starlight had quickly caught up and the two mares were starting to look exceptionally obese. Both their middles sagged low beneath their bodies and Trixie could feel her stomach starting to touch the floor, it’s soft outer flesh kissing the cold crystal surface that covered the whole castle. Starlight’s was not only touching the floor but had spread a little, pushing her hooves outwards from her slightly and forming a small belly-bed for her to rest on.
“Mmffff!” Trixie tried to manage a word between the mouthfuls of cake but failed, the noise caught Starlight’s attention.
“Awww, jealous of my fine middle? You’re not too far behind.” The pink mare teased her friend with delight. “I thought you weren't enjoying this but clearly you are a little. Let me help you along.”
Starlight’s horn glowed with more intensity as she managed to put in a little more effort to her magic, the cakes kept flowing into Trixie’s mouth but they suddenly started to go down much easier than before. Her pace quickly increased and she was swallowing cakes like over twice as fast, the gooey treats disappearing fast.
“It’s meant to be for ponies who have trouble eating but, I modified it just a little.” Starlight giggled, casting it on herself and picking up the pace herself. She stopped feeding herself with her hooves and started to move, her fat bloated stomach dragging along the floor as she positioned herself next to Trixie, who’s own belly now had overtaken Starlight’s and was gently ever so slightly lifting her off the ground.
“I suppose I should be in the right place, we’re going to give Twilight quite the show when she returns.”
Starlight watched a slight panicked look appeared in Trixie’s eyes. She could tell she had no idea what she meant, further elaboration was clearly required.
“Well we’re rather close to the door still, and there is still a lot of cake to go. I think we could quite easily block it with our rears. The bellies won’t hold all the cakes forever, it’ll start to go elsewhere. Trust me I know…” Starlight trailed off. There was little Trixie could do to stop her, her own magic was too weak against Starlight’s to stop the relentless onslaught of cakes filling her gullet. Both mares middles were now more than impressive in size, with their stomachs forming small beds that had made their upper bodies and legs rise from the ground. Neither of them were going anywhere anytime soon. Trixie hoped Starlight, or even Twilight might have a spell once all this was over.
Trixie suddenly felt a weight behind her that she hadn’t quite noticed before, the overwhelming sensation of her cheeks being stuffed and her bloated stomach expanding beneath her was more than enough to keep her mind occupied but something else weighty had made its presence known. She was suddenly very aware that not only was her stomach still expanding but her rear was catching up with her belly. Trying to crane her neck around she caught a glimpse of two fatty orbs that had risen above her back and were only rising further as Starlight still pushed more and more into her mouth.
“Don’t worry, that will get even more expansive.” Starlight laughed. “I told you your stomach can’t hold it all, it has to start going elsewhere. I mean just look at me.” Starlight said leaning over as best she could pushing her body into Trixie, without looking she felt her friends enormous flank against her own as their two bodies came so close Trixie could feel the huge weight of Starlight against her. Still chewing she blushed as she felt the pink mare gently rub herself against Trixie before gently moving away to continue her eating.
It wasn’t long before the girls started to touch without needing to lean into each other, their overblown bodies were bloating out in every direction. Feeling her own stomach start to smoosh into Starlight’s Trixie felt slightly comforted by the warmth of her friend against her. The more that the two mare ate the more warmth she felt, each second more and more belly and butt cheeks pushed against each other - both of them now easily the size of Trixie’s wagon, each, and still growing.
For the first time, and now she was confident Trixie was completely immobile she Starlight decided to allow her a moment of rest to speak and she took stock of the remaining cake which had dwindled rather quickly. At first all she heard from her obese friend was pants as Trixie gasped for air, her new size making her struggle for a few seconds as she quickly became used to it. Eventually she squeaked out her first words since the session began.
“I-I know you said you made a lot of cakes but I didn’t expect we had to EAT THEM ALL!” Trixie yelled. She couldn’t do anything but express her annoyance, even though without letting Starlight know she was starting to enjoy it just a little bit. She could hardly do anything regardless, her fat useless hooves rested gently against her hefty belly. Bloated rear rising steadily above her and her chubby face starting to sink into her spare-tyre like neck. She turned her head as best she could to observe Starlight, her body almost matching her own with a little difference in size of being that Starlight had gained 10 or so more pounds than her partner. There was little movement between the two of them apart from the inevitable jiggling of their rears and bellies that is unavoidable at their size.
“Of course we had to eat them all. I wouldn’t have had it any other way.” Even though Trixie couldn’t see it she felt that sentence ended in a smirk. “There’s only one thing left to do.”
“What, what is there left to do? We can’t do anything!” Trixie yelped.
“I still don’t think we are quite blocking the doorway.”
Trixie had no time to reply as she felt the remaining cakes start to fill her once more, body expanding once again. Her stomach seemed to be nearly done, and although still getting larger it wasn’t quite keeping up with her rear which began to push backwards. She imagined Starlight’s was doing the same.Within a few moments she felt more coldness as her cheeks pushed up against the castle walls. Trixie could feel her fattening rear starting to smother it with ease, her blubbery butt almost washing over the walls and large crystal door that they had previously walked in through, walking starting to seem like a distant memory as Trixie tried to move her bloated body but to no avail.
The door creaked as both the mares rears began to push into it, the latch starting to strain but holding against the tide of fatty flesh that pushed into it more with each second that passed, the lardy butts coming together and cheeks gently settling in against one another as the tide of cakes began to slow. It seemed Starlight had made just the right amount to satisfy her little bit of fun.
Finally, Trixie and Starlight both gulped down their last cakes. There was a moment of silence, before almost in unison both of them finally had their bodies catch up with their eating as the loudest, almost ear shattering noise as a unified belch left each of their lips.
“UUUUUURRRRRRRR-AAAAPPPPPPPP!”
Their bodies wobbled and swayed as the vibrations gave more movement within them than they were now capable of with hooves, fat slapping against each other as they rippled and collided with one another. For what seemed like an eternity but only seconds the two enjoyed the feeling of such a large amount of blubber so close before it came to rest. Starlight spoke first.
“Mission accomplished.” She giggled, waiting to hear what Trixie had to say through her bloated lips.
“Well if your mission was to make us the fattest mares in Equestria I’d say so.” Trixie replied.
“Please, there’s two of us in here - I’ve had far more extravagant sessions by myself. I just wanted to have a little fun with a good friend.”
“You could have just asked.”
“I could, but there’s no fun in asking, Plus I also didn’t know what you’d say…” A slight blush starting to form on Starlights cheeks.
“I might have said yes.” Trixie replied indignantly. “Although maybe not quite if I had known I’d be this big. Now what?”
“Now we just wait for Twilight to come back.”
Trixie started to worry again. “Wait, you don’t have a spell to shrink us down? I thought you had said you had done this before?”
“Of course! But usually Twilight is gone for quite some time, I have a spell - but it takes at least a few days to get back to normal. We’ve been in here a little while, she should be back in oh...the next ten minutes.”
“TEN MINUTES?”
“Twilight doesn’t know I do this either, I think the way to tell her should be something interesting. She’s going to open that door you know, the one our butts are currently blocking?”
“Oh...dear…”
“Starlight?” A distant shout came from down the hall, Twilight had returned - clearly a little earlier than anticipated.
“Ah, here she is now. Don’t say a word. Promise?”
“Fine, but I’m blaming you when she asks what happened.”
“Suits me.” Starlight replied in a smug tone.
The sound of trotting hooves got closer and closer. “Starlight where are you?” The question came again, but neither mare made a peep as Twilight got closer to the two of them.
“Odd, I don’t usually shut this door…” Starlight giggled, she often heard Twilight mumble to herself when she was perplex. It always made her smile. “Aha, found you!”
Twilight wasn’t quite sure what happened next, she came to the room Starlight was in, but even though most of the crystal doors in the castle had a semi see-through window this one was almost black. She could have sworn she heard a faint squeaking noise as something large rubbed against it but she paid it little attention.
As the latch was finally given reprieve from its job of holding back the wall of flesh, poor Twilight got the full brunt as the doors flung open and a sea of ass that was squished far too hard against the doors finally found just a bit more space to expand into and push outwards, overwhelming the princess who was unable to hold back the tide of quaking, jiggling mass that came towards her without warning. Her eyes filled with pink and blue as she overwhelmed by the two obese lardy mares, and disappeared between the two of their rears.
After a few moments a groan was heard, followed by a question.
“Really?”
