Meanwhile with an overachieved student.

“-Knock-knock-knock. ‘Hello!’ Twilight this is an utmost urgent emergency of the worst possible things!” let out Rarity getting antsy at her friend's doorstep.

“ugh mug Spike door Spike urgh ‘Spike!’ Spike?’ arrgh who could possibly need something at this hour?” let out Twilight as she tossed and turned only to throw her covers off as she got up.

‘I swear whoever it is it better be an emergency’ she thought groggily making her way to the door as the insistent knocking continued.

“-thonk knock bang-bang Twilight ohh!’ knock-thonk thump-thump arrgh what I’m coming arrghh huh Rarity? Rarity wha-whoa slow down what’s wrong?” began Twilight as she finally made it to the door only to find Rarity in a complete mess To rush in the moment she opened it.

“Rarity what are you doing it’s the middle of the night?” asked Twilight.

“RARITY CALM DOWN I’M FINE IT’S JUST A LITTLE HIGH AND DOSNT HURT SIS RELAX I’M OK NOW SIT!” let out Sweetie having had enough of her sister's drama to last her a lifetime feeling her sister take to the command.

“…” ‘Either I need coffee or I just found my reason’ thought Twilight a muffled but unmistakable squeaky voice made itself known to her ears.

“Um let me guess sleep eating?” said Twilight trying to joke, as her friend sat in front of her.

“un-un fortunately not I remember eating her whole like some marshmallow she-hehblorknmngh” began Rarity shutting down as she let twilight examine her belly.

'I ate her no-no-no you know what happened she’s fine’ she thought feeling Twilight poke her belly while she felt her sister move about seeming to be gentle.

“Inhale exhale ehem um Twi dear I do believe I’ve gobbled my sister” tried Rarity simply stating the obvious as she put her hoof to guide Twilights to her sister.

“How?’ how in the name of starswurle did she even swallow her?” she thought aloud as she felt one of her students seem to just relax in her friends gut.

“Uh how did this happen, dare I ask?” asked Twilight as she put her ear to her friend's belly.

"Uh-IT HAPPENED UM WHEN SHE GOT MAD AT ME I DON’T THINK SHE WAS THINKING IT SCARED ME AT FIRST BUT SHE PROMISED SHE’D LET ME OUT AND SHE DID BUT THEN I ASKED HER IF SHE’D WELL DO IT AGAIN BECAUSE I’M UH WELL TWILIGHT I’M BALD SHE ALMOST MADE SOUP OUT OF ME THE FIRST TIME BUT SHE CHANGED HER MIND I GUESS SHE LOVED ME TOO MUCH” interrupted Sweetie as she put her hoof to what she assumed was Twilights own.

“Hugh um ok why don’t you come with me Rarity I think we can get her out easy kinda like burping,” said Twilight as she helped her friend up.

"This way just relax she fine but she is bold though,” she said as she guided her distressed friend to her lab.

“RARITY IT’S OK SIS I’M FINE REALLY IT’S ACTUALLY NICER THAN YOU MIGHT THINK WARM, SNUG, SOFT, AND A HEART FOR A LULLABY TOO” continued Sweetie trying to keep her sister calm as she felt each step she took.

‘at least she’s happy giggle oh this just better be a dream but I don’t think it is so Sweetie let’s see if we can’t get your sister to burp you out I know just the spell too’ thought Twilight as she made her way ahead of Rarity watching as she seemed to be on autopilot.

“Just sit over here I’ll be right with you,” said Twilight pulling out a stethoscope, rubber gloves, and a small duffle bag.

“Twilight? Do you think am I a monster?” asked Rarity finally breaking her own silence as she looked to see her friend getting doctor’s equipment.

“Oh um no, is it because you seem to have eaten your sister… no, she’s fine too so no not really” answered Twilight as she brought her gear to the table next to Rarity.

“Ok test subject female unicorn adult second subject seems to of been ingested by the first the reason, unclear,” said Twilight monologing as she unzipped the duffle bag revealing a small medical device with a screen and a long series of wires leading to a hoof held a device with a scope on it.

“I do… um, what is that I can get her out I just need you to check on her darling… ‘please don’t cut me open!” said Rarity ending quickly as she shied away from a strange looking contraption her friend had assembled.

“Twilight no don’t it’s ok please don’t hurt her I’m fine really just get her some tea getting her worked up won’t help anything!” let out Sweetie shocked at what she heard her sister fuss about.

“TWILIGHT WHATEVER SHARP THING YOUR HOLDING PUT IT DOWN NOW!” demanded Sweetie as she began fussing.

“relax it's an ultrasound, Sweetie. Rarity sigh I’m not going to just cut you open its absurd not to mention a health risk for both of you it’s just something that’ll let me see you, Sweetie, Rarity knows what it is” explained Twilight looking at Rarity bemusedly.

“…its ok darling it’s not sharp it’s an ultrasound,” said Rarity caressing her filly filled belly.

“Um what’s an ultrasound?” asked Sweetie finding her sisters hoof.

“It’s a device that will let Twilight see you, dear,” said Rarity explaining it as best she knew how.

“Oh um ok just don’t let her hurt you even if she doesn’t mean to” finished Sweetie as she stopped fussing.

“right now let’s see what we can do about your um occupant,” said Twilight as she put on a pair of gloves tacking a jar of clear jell out of the duffle bag as she went about her procedure.

“Now darling what in the wide world of Equestria do you intend to do to get her out I assure you I have that covered I just brought her here to be checked on” began Rarity as she allowed twilight to apply the gel.

“Just a simple spell” answered Twilight as she turned the device on a strange gurgling thrum coming from it as she began using it in cooperation with a spell making the gel glow.

"Well she’s healthy, strong heart by the way,” she said as she listened to two hearts thumping and thrumming.

“Now let’s see if we can’t hear you better,” said Twilight as she grabbed her stethoscope and placed it against Rarity’s lumpy filly shaped belly.

“Now Sweetie mind telling me how you found yourself as a meal?” asked Twilight as she moved the stethoscope around to where she thought sweeties head was.

“um well it’s kind of a long story but ...sigh I made a mess and broke sumthing really important and though at first I thought she was going to well you know what happens in here, but after a while it became clear because I asked her why she ate me and at first I thought it was because I’m just too much trouble and she keeps saying I’ll be fine but I tell her I’ll melt and that I thought she loved me but then she tells me she does love me asking me why I thought she didn’t. Began Sweetie as she retold her experiences.

“…” ‘Well?’ thought Twilight as she listened looking up to see her friend blush.

“And I say because she ate me then I asked her if it was because she wanted to make me a part of her. But that’s not it either she says as much as she loves and wants to spend time with me that she just didn’t have time to run around an pick up after me that I’ll be fine, asking me if I thought she was just going to leave me in here. And she admits she didn’t think it all the way through.

“…” twilight raised her brow as rarity turned away flushed red as they both listened to sweeties Side of the story first.

“But even as she ate me, I mean one minute I’m apologizing and the next my heads in her gullet but as I struggle she rubs and pats my back like she does when I’m upset. Eventually, even with how much I tried to pull myself out, it was like trying to well you know those hoofs escape woven trap things where the more you pull the tighter it gets it was like that except it wasn’t getting tighter it was like a suction cup. I couldn’t free myself but I knew she wasn’t going to hurt me like a voice in my head or something and eventually all I can do is squirm and fuss as I felt her slurp up my tail like a noodle while I’m forced into her gut.” Continued Sweetie as she listened to her sister's heart making her feel safe.

‘How they hey did you swallow her?” Thought Twilight as she looked at the monitor seeing an image of a filly snuggly tucked away in her friend's belly.

“ Then she says she’ll let me out in ten minutes or until she finished fixing my mess. But I calm down enough that I bargain and if she finished earlier than ten she had to let me out right there and then and she says if I’m quit she will. she also tells me that my squirming is helping get the stress out of her muscles. so I have to give her a message from the inside. From the experience, I'd say, she liked it. Soon her gut fills up with this itchy substance and it burns my eyes nose and throat but I keep my end of the bargain and I stay quiet until it gets too high.” Said Sweetie watching as the clear fluid continued to fill up around her not bothered by it as she told her story.

“…” ‘You could have killed her’ thought Twilight as she tried to find her friends reasoning.

“So I try letting her know by kicking and her… I think by the way gravity felt she sat down and the shift in posture allowed my head to stay above the liquid but I swallow some and it really hurt, made it harder to tell her what’s wrong. But a ways into it I fell her magic wrap around me and she makes this bubble thing and the fresh air felt nice and cool too. plus she somehow made the fluid drain out a bit before it stops. But then she tells me it’s ok and stands up and the liquids washed over me I scream but they don’t hurt me and when I opened my eyes the liquid had encased me but the bubble kept it from drowning me but what really scared me was I could see chunks of my mane and tail dissolving and my light charm, I did I light charm but I almost lost it a few times. I thought if I did I wouldn’t have enough strength left to do it again. but as I relaxed I let it fade a little and I notice the bubble giving off enough light that I can see and I realized I was bald and I still am…” said Sweetie posing for a moment as she thinks.

‘What am I going to do I don’t want to walk around like this it's humiliating’ she thought as she brought her hoof to where she could see it looking at her pink skin.

“She’s hairless! You actually burned her fur off?” let out Twilight shocked.

“Mng I wasn’t thinking- hay! Let me finish! And leave her alone Twilight I’m fine” began Rarity before a small kick and voice interrupted her.

“…”

“Ehem then I felt her going down the stars because gravity made me slide upwards. When she gets to the bottom and levels out I keep asking what she’s doing but I don’t think she could hear me her gut was making all kinds of noises. Then I realized she was eating I couldn’t believe she could still be hungry after she ate me! but then I finally get my voice back enough that she can hear me and I tell her what happened and after a short talk I felt something wet on my bold head as I look up I see a bubble of white fluid ...it’s milk. But before I can do anything with it my horn pops the bubble and it falls on my face, but I realized it helped my eyes not burn. so I leave them open and shortly after that another bubble comes and I’m able to drink it at first I was thinking about germs but I always ate of my sister's plate.

‘Gross though I ate off moms huh’ thought Twilight as she looked to the monitor again seeing a perfectly healthy filly.

“So I thought I might as well and my throat felt better but then she gives me cookies and a sandwich while the rest just falls into the liquid and I watch as it dissolves and turns from color to a gross mush. Soon the liquid is a bit more of a thin paste. Then a few minutes and a short conversation later she says she has some things to do and I can’t stay awake anymore but I’m calm enough that I know she’ll let me out I wake up a few times because she moved a lot.” Continued Sweetie not bothered by her sister’s bodily functions feeling safe in her bubble of her sisters magic.

‘there’s magic involved’ I’ll need to study it!’ thought Twilight unable to find a good reason her friend would cannibalize her sister.

“But the third time I wake up in her bed she had pillows and blankets surrounding me, I’m cold so a rollover and grab one and roll over the other way like a burrito ironically. But then she comes in suddenly and my magic flared up next thing I know I’m encased by all the pillows and blankets. She startled me but why’d my magic act out like that? Anyway, I find my way out and we talk. she’s beside herself but I honestly aside from the grossness and being afraid I was going to be soup it wasn’t all that bad and she’s my sister and I told her that” said Sweetie as she looked around feeling tired.

‘How could you have just up and ate her she’s your sister for Celestia's sake’ pondered Twilight as she started taking notes.

“But… he-heh I might have told her she could eat me so long as she didn’t make soup outa me I don’t think she understood what I was trying to tell her. now that I think about it I was resigned with myself being her meal because well it felt… once I got over it I realized I liked hearing her heartbeat and listening to her body and it kinda feels like a cross between a warm bath and a hugging massage in here… um twilight I don’t want to come out but it's not fair far for my sister, I’m bold Twilight you wouldn’t know any spell that can help my fur grow back would you?” finished Sweetie nervously. ‘This is weird’ she thought as she curled up snugly.

“?” ‘She’s really fine with it auh I think I know why you ate her you silly pony’ thought Twilight as she confirmed a suspicion.

“…um Sweetie do you know if your sister can let you out and how she managed to swallow you in the first place?” asked Twilight looking to get to the bottom of things.

“um I trust her enough and she did it once so-’ of course I can that’s part of why I came to see you um could you by chance help her with her well baldness?” answered Rarity cutting her sister off as she held her belly.

“I… um, I’ll have to see her first,” said Twilight as she tried to understand why Sweetie was so calm. ‘at least she’s not freaking out’ she thought as she moved the ultrasound around her friend's stomach looking at the screen.

“But I don’t want to come out its cold out there,” said Sweetie shivering at the idea. “Can’t I stay here? Rarity will take care of me” she finished as she relaxed leaning into her sister's warm guttural embrace.

“…Sweetie, why would you want to stay in there? It’s gross not to mention dangerous it takes a pony three days to digest a mass of meat of 56 pounds and five ounces plus you’ve already lost your fur” questioned twilight as she looks at the readings on the monitor.

“I… because I’m naked and it’s warm in here plus I can just ask and she’ll let me out when I want her to!” let out Sweetie losing her patience as she wriggled herself in deeper.

“that doesn’t make… arrgh mnn sigh fine but while you’re in there I going to use the opportunity to perform some tests then you're coming out whether you want to or not” shot back Twilight as she found herself yelled at.

“oh really well I’m not coming out so unless you can make my sister break her promise and spit me out then you’re out of luck, besides you said its dangerous to teleport something that’s inside of something and I have a feeling its even more dangerous with something that breaths so ha!” countered Sweetie as she let herself lay loose.

“Well if you want t-’ TWILIGHT!” Twilight began before Rarity cuts her off.

“…” ‘And here comes drama’ thought Twilight as she bit her lip.

“…Sweetie dear I think I know why you really want to stay in there. You’re embarrassed aren’t you?” began Rarity as she put her hoof to her sister's location.

“…. I’m fine I uh… uh huh” let out Sweetie nervously as she put her hoof against her sisters.

“Would you come out if it were somewhere she couldn’t see you, you have nothing to be ashamed of darling even without your fur you as adorable as ever,” said Rarity as she scowled at Twilight.

‘but she’ll see me anyway but it’s just Twilight... sigh thank Celestia it’s not diamond ...sigh ok but not right now it’s so warm in here giggle’ thought Sweetie as she went over her sister's question.

“Um I five minute’s it nice in here and your heart makes me feel all fuzzy inside,” said Sweetie thinking things over.

“Hmmm, alright darling” answered Rarity as she smiled at her sister's words.

‘giggle you’re so sweet’ she thought as she looked at Twilight nervously as she felt herself blush before turning serious.

“See now that wasn’t so hard was it Twilight I know this is well deferent but please how do you think I feeurrrrp…. He-heh giggle, sorry but this isn’t my usual diet giggle ugh oh come on Twilight you can at least take a card from pinky every once in a while I’d of gone insane by now if I didn’t look at it in multiple views” said Rarity looking Twilight dead in the eyes as she felt her sister get comfortable again.

“…” ‘Well ehem 'SURE' so first on the list check for sociological damage’ thought Twilight at hearing her friends pun. "Ok then give me one minute so I can get a few tests ready,” said Twilight as she walked away putting the ultrasound sensor back on the mount in the monitor while letting Rarity take the stethoscope from her.

‘Now where’d I put that psych evaluation question and answers graph?’ She asked herself as she walked about her basement laboratory.

“Now why do you want to stay in there? Besides my heart darling” asked Rarity putting the stethoscope on as she listened for her sister’s response.

“…I don’t really know I just feel um well it’s soft, worm, and it feels like a hug and I ...Um, curious giggle sorry I don’t know I just feel uh safe good he-heh” answered Sweetie shyly as she felt the walls hold her warmly.

“Now darling it’s a bit more complicated isn’t it do you honestly feel safe in there you’re not scared?” said Rarity as she asked her sister how she felt.

“Um yeah sis I know you won’t hurt me and you may have scared me and cost me my um pelt and um are you, ok sis, I’m fine really I am” responded Sweetie as got the feeling that there was more than what her sister let on.

“…um well yes but… oh darling I just don’t know what came over me plus the fact that I just up and ate you without thinking twice… and now I ate you again Sweetie I just don’t know what to do right now aside from whatever Twilight says will help you” answered Rarity as she thought of her recent choices.

“giggle Rarity I’m fine and I asked you to eat me the second time alright inhale I asked you to eat me because I’m trying to sort out what I felt when I’m in here I can’t explain it I feel safe and fuzzy, warm and a bit nervous but I think I feel loved when I’m in here oh what did I taste like?” said Sweetie as she forces herself to talk about what she felt asking her own question.

“Oh um well if I’m going, to be honest, you taste like a marshmallow, so you're curious and you can’t explain how you feel huh well I think I feel it too and I know where it comes from” answered Rarity as she sorted her own feelings.

“Really… um, then what is it?” responded Sweetie curiously.

“well, it comes from knowing someone you love cares and loves you plus I think the other half you feel is the same thing I feel after a day at the spa and in that a lack of stress” answered Rarity as she saw Twilight looking at her like she had gone mad.

“Oh you mean well a mix of relaxed, peace and comfort?” questioned Sweetie as she felt her enclosure get snug again.

“Sort of but the bigger part ill explain once you’re out here so I can see your adorable little face again,” said Rarity as she huggled her gut.

“Darling would it be ok if I let you out early?” asked Rarity looking at twilight as she perked up at the inclination.

“…um giggle sigh ok I think I’m ready to come out any way I’m starting to prune” answered Sweetie as she examined herself finding her hooves to be wrinkly.

“That’s wonderful... Well aside from the pruning” said Rarity relieved her sister had agreed as she smiled at Twilight.

“Then it’s time to get you out of there my little marshmallow,” said Rarity as she got up and walk over to Twilight the stethoscope hung around her neck.

"Darling is there somewhere private that I could well alleviate a certain passenger?” asked Rarity with a nervous smile feeling herself blush.

“Here before you do anything I need you to put these on I'll help so I can be sure it’s done right,” said Twilight as she held out a bundle of nubbed wires. ‘Then I can finally get some sleep and finish this wacky nights study in the morning’ she thought grumpily removing the stethoscope from her friend's neck as she replaced it with a necklace like contraption.

“Oh alright but whatever are they for that suit looks like last week’s fashion disaster,” said Rarity not sure how to make heads or tails out of a suit that seemed to be made out of a network of wires and small dots as she followed Twilight over to a corner.

“This will tell me what you’re magic is doing to keep her safe plus help me figure out how the hey you swallowed her in the first place?” said Twilight as she had her friend stand on a white platform with three disconnected walls and a strange roof.

“well I could just tell you that when I was her age I used to think my special talent was swallowing things and I worked my way up to bigger things but I swear this is my first filly I mean pony” began Rarity as she slipped on a pair of paints finding they went up to her chest and barely covered her legs at all while twilight helped her get the rest of the suit on.

“Whatever is that for?” she asked as Twilight put a strange series of wired rings on her horn with some sort of hat.

“Well, this thing could use some T.L.C” she finished.

“it’s going to help me identify what you’re doing with your magic there’s no way you swallowed her without it in some form” answered Twilight as she plugged the color-coded ends into a decahedron shaped device before turning it on.

“mug you sure have a strange way of moving you hips geez sis giggle sigh huh giggle alright I’m coming just relax" let out Sweetie softly as she felt her sister seem to move into odd positions before feeling her sisters magic wrap warmly around her letting herself fall into it as she wriggled to try and make things easier for her.
‘mnph giggle just like a hug’ a wet hug snort he-ha giggle’ she thought as she felt the muscles clench around her tinny form and start pushing her up while she felt herself shift around.
“giggle Rarity that tickles he-ha ha giggle whoa mph here we go” let out sweetie as she felt the walls vibrate and rub on her skin hearing her sister belch while her sisters magic didn’t help with the sensitive nature of it.

“Buuuulkurrp excuse me ehem ah there you are” let out Rarity belching as she felt about for her sister finding her as she began pulling her out.

“huh sow you use your magic to help like it wasn’t obvious in the first place huh well that’s interesting your muscles shouldn’t be able to stretch like that- wow ok I take it back this is, is … strange?’ thought Twilight as she watched the monitor and sensors pick up on both biological and magical information watching a three-dimensional representation of her friend's body mimic what the scan picked up looking back and forth between rarity and her 3D counterpart.

“mngh geez sis relax whoa mngh hophmngh” let out Sweetie as she felt her sister swallow her again before being pushed back up feeling her sister pull her up with her magic while she felt the muscles push her out. 'Huh ok mngh ugh feels like she’s trying to hug me to death' she thought.

‘Oh come now darling your coming out on way or another’ thought Rarity as she finally got her sister's hind legs into her vision.

‘that’s it dear just hold still the more you squirm the harder it is’ she thought as she managed to pull her sisters posterior out finding the rest to be easier as she leaned forward.

‘This is well strange huh well with this I should be able to figure out the rest’ thought Twilight taking notes as she watched the monitor and her friend looking at how little her throat was stretched.

"Well she is bald” she stated under her breath as she watched.

“mngh mph” let out Sweetie as she felt her hooves touch something cold shivering as she pulled her legs in. ‘cold, cold, cold agh Rarity I told you I was bald it's freezing out there I don’t want to come out it's warm and nopony can see me like this’ she thought as she tried to force herself back in.

‘huh whoa hey no, no, no awe pony feathers, gagh the light!’ she thought as she found her head to meet the outside feeling her sister's lips slide over her face.

‘There we are darling oh my you look miserable and freezing awe come here you little marshmallow’ thought Rarity as her sister hooves slide out of her mouth.

“Oh darling come, here it’s good to see you again mnn,” said Rarity as she picked her sister up into her magic holding Sweetie against her chest and wrapping her in as much warmth she could generate with her magic and body heat.

“Cold, cold, cold auh mmm mnn sigh” let out Sweetie as she curled up finding it did nothing before she felt her sister’s magic lift her up into a warm embrace.

“Mmm-sigh thank you auh- did I… sigh oh come on!” said Sweetie as she looked at her flank for something she found was still out of reach.

“Auh sigh mmm I love you sigh” sighed Sweetie letting herself fall limply into her sister’s embrace offering her own in return.

_______________some time later

“Burr hey that’s cold” let out Sweetie as twilight prods her with some glowing metallic device.

“Hold still Sweetie just one more,” said Twilight as she ran a device with three sphered heads alone sweetie’s skin.

“Twilight you could be a little less stern she’s been sitting there forever I thought you only needed one of these treatments?” said Rarity as she watched her sister sit on a strange counter with glowing lines.

“I did I just need to be sure I get a good coating” answered Twilight as she ran the device over sweeties scalp.

“You’re lucky you didn’t damage her nerve cells and hopefully this stem cell treatment will help the cilia cells heal faster if at all,” she said as she went under Sweeties' chin.

“Now please no more random meals especially fillies, and ponies in general!” finished Twilight as she went for another pass.

“Very well if I’m honest I don’t know what gave me the idea in the first place “answered Rarity as she sat in a chair next to her sister.

“Meh- Twilight when are you going to be done? I have to use the bathroom” said Sweetie as she held still.

“Almost there now just a minute you gonna have to hold it the treatment takes a few minutes to set otherwise it won’t work right” answered Twilight as she looked her patient over using a sterile tongue press to guide Sweetie into a standing position less she remove the film coating Sweeties skin forcing her to start over.

“Ugh fine how long?” let out Sweetie antsy.

“just ten in the meantime I’m going to run some tests on your sister for a few minutes so just sit here and don’t touch anything, nothing, just sit tight it won't take long,” said Twilight smiling at Rarity.

“And what are you going to do?" Asked Sweetie seeing her sister looking nervously at her. ‘She better not use her as a Ginny pig’ she thought as she watched her sister and magic teacher exchange looks.

“Just a few scans and small test to check a theory” answered Twilight smiling at Rarity.

“It’ll be fine darling just sit tight and i'll check on you in a few minutes ok,” said Rarity reassuringly as she used her magic to lift her sisters chin up looking at the oil that covered her bald body.

“…sigh k” let out Sweetie before giving twilight a stern look. ‘You better be careful’ she thought before she smiled at her sister as she watched them walk to a different part of the lab.

“I’m watching you,” said Sweetie under her breath as she stood still as she could while having to pee.

“Stand here now how long has it been since you’ve used this... off talent of yours?” asked Twilight as she had rarity stand on a scale.

“Well, not a while since sweetie was born” answered Rarity as she thought things over.

“And how long has that been?” asked Twilight as she measured Rarity’s jawline.

“Almost seven years I suppose give or take why?” answers Rarity wondering why her friend was so interested in her strange ability.
