sweetie's punishment

"Are mmm auh yyuo mmm finnisshed auh ye-et?" questioned rarity as she felt like she'd pass out. 'mmm, I need to get one of these mmm' she thought as she felt her vulva clinch shut repeatedly.

"Almost just hang in there" answered twilight as she worked on finishing her patient's electrography exam.

"Oh auh, k I the-auhnk auh mmm auh Aaah aaaaaaaaaah mmm mng mn mn" let out rarity as she feels her vagina clench tightly as she felt a massive climax. 'im cumming mmm oohh yes mmmm I can almost taste it mmmm that's seven mmmm wonderful' she thought as she felt herself slide in deeper feeling her checks lay flat on the platform.

"Rarity? Are you ok!" let out sweetie concerned as she darted to check on her sister before finding herself in a magic bubble. "Hay! Twilight what happened what is that is she bleeding?" questioned sweetie still running as the bubble just spun to keep up with her worried her sister might be hurt. "Rarity answer me are you ok!" she shouted wondering why her sister was moaning while her face scrunched up and her body spasmed.

"Sweetie its ok she's fine calm down agh sweetie belle!" began twilight as she tries to assure her student everything was fine having to yell as sweetie stops to quickly curl up looking wide-eyed at her sister. "Sweetie she's fine if you give her a minute i'm sure she'd love to tell you how she feels," said Twilight as she conformed her bubble around sweetie bringing her in to look at her as she waited for the final scan to finish.

"What happened! Why'd she shake like that? Why's she moaning? Is she hurting? What happened it looked like her bowels exploded! Whats that white stuff? Is she going to be ok? Is she bleeding why's her blood white? What did you do to her! I SWARE I'll MMPH MMNGH-lick- WHAT DID YOU DMMNGH- RRRRGH" let out sweetie faster than she could hear herself before a purple hoof is placed over her mouth quickly licking it away as its owner shakes her saliva off in disgust blurting out a torrent of questions before finding her muzzle clasped shut by magic.

"Blek whoa slow dawn she's fine, she's fine I didn't do anything!" let out twilight struggling to keep up with the onslot of questions as she uses her magic to gently shut sweeties mouth. 'geez and I thought her sister was talkative' she thought as she looked to see that rarity wouldn't be helping any time soon as her thighs twitched while her tongue hong out of her mouth a Rosie pleasured expression across her face.

"MMMMGG MGH MPH! SOB SNIFFLE" Tried Sweetie losing herself as she starts getting scared.

"Hey-hey easy she's fine almost done easy" began twilight as she brought her student into a warm hug feeling her squirm and try to get free but to no avail, her grip winning out.

'what'd she do to her rrgh ill ohh what can I do please be ok' thought sweetie as she gives up wondering what Twilight had done to her sister.

"... Hey look she's done now just let me shut it off and then you can go check on her i'm sure she'll be happy to explain it to you ohh mmph," began twilight only to lose her grip as a worried filly knocks her over she shuts the medical apparatus down leaving full layered holographic medical representations of her friend in its place.

'oh, how do I explain it she never heard it this way before' thought rarity as her sister looks at her in curious worry.

"Rarity?" called sweetie softly concerned her sister might have been hurt as looked at her sister. 'whats wrong with her... Vegina it's all wet and puffy?' she thought, wondering if her sisters cries were pain related or not confused untell she remembered that recently had a similar experience. "...so did you enjoy it?" asked sweetie connecting the dots.

"Uh i'm sorry darling what?" responds rarity coming out of her head long enough to hear what her sister said. 'did she just no how would she know that itmpht...' she thought ending abruptly as she remembers the night prior.

"Well did it feel nice?" asked sweetie innocently as she smiles sweetly at her older sister.

"Hph I uh ...yes" hesitates rarity as she tries to think of an answer before hearing her mouth answer for her as she blushes a deep crimson. 'why did you just say that oh now what do I tell her that the whole letter to Celestia is a lie?' she thought nervous and thinking about the subject was just making her more aroused.

"Um, so why does your um pee... Heheh hem... ?" began sweetie nervously stopping short as she felt herself blush. 'whats the white stuff if it's not blood?' she wondered as she looked at the pool of juices beneath her sister. "Why were sitting on that ...thing?" finished sweetie trying to distract herself from her sister's full blossom.

"Uh heheheheh well darling i-i think well you see mnph" tried rarity stumbling over herself as she tried to think of an easy way to educate her younger sibling.

"Its part of the F.3D.M.M.A system well its part of the scanning array the apparatus needs to be inside so that the scan has something to bounce back from as well as act like an ultrasound with a built-in x-ray and sigh and a whole bunch of things but the main thing is it was for medical purposes and practice" cut in twilight explaining as much as she could simplify seeing the confused looks on her two patients ending in awkward silence.

"And I think I figured out how you managed to swallow her and regurgitate her with as little damage as was done," said twilight breaking the silence as she brought a chart over with her magic.

"Well, then how and why did I east her it's not like me!" shouted rarity as she quickly got up only to fall back on her rump her legs giving out from under her causing the fluid beneath her to splash.

"Rarity relax its actually a good thing mostly but you need to be careful its called voreism and in simplest its an eating disorder that affects your magic when young it usually manifests as a subtle thing like eating random things like none food items such as jewelry to pillows and even garbage but in some cases it can turn into something much darker if its not managed properly," explained Twilight as she went over her chart.

"Uh ... ?" tried rarity as she fails to make much sense of her friend's explanation. 'garbage why I never' she thought as she listened to Twilight continue to say something else.

' well that's huh ulk hmmm' thought sweetie as her sister falls felling something wet hit her face being met with a salty, tangy taste before turning sweet like marshmallows. 'uh, why does it taste sweet?' she ponders as she thought back at a time she got hit with toilet water remembering the awful taste of her own urine. "Rarity?" she calls softly as she wonders if her sister was ever going to tell her what had come out of her nethers, while she sticks her hoof in finding some of it to be thicker then the rest. bringing her hoof to her nose smelling something that smelled like her sister's natural scent, but stranger and with a hint of vanilla. ".?." 'it's actually not that bad' she thought as she licks her hoof.

"And how do I manage it what are the risks"?" Asked Rarity, seriously as she looked at twilight for answers worried she might find her sister a true meal next time.

"relax! with some research I should be able to make a substitute?" let out twilight hurriedly as she tried to keep her friend calm.

"substitute for what your not making sense?" said Rarity as she tries to keep from strangling the answers out of her friend's throat.

"sigh rarity you know what for the thing is a long time ago well you know the story of nightmare moon" began twilight trying to explain something she barely understood herself.

"and what about them there just filly stories told so they'll behave or at least that's what my father told me" inquirers rarity holding her sister closer resting her chin on her sister's head. and luna's reformed I dont understand unless you're saying there true ...please tell me they aren't true gulp" finished arity swallowing nervously. 'just relax you haven't let her finish yet' she told herself as her mind comes up with conclusions non too pleasant.

"your right I dont know much about it or what inspired the stories but... 'wait why dont we just ask her!" finished twilight as she quickly moves to get a fresh sheet of parchment. "spike! sigh pop SPIKE" lout out twilight calling her assistant sighing as she teleports a disgruntled drake to plop down in front of her.

"whaaa huh ahhh" let out spike as he wakes up suddenly only to see a rather embarrassed sweetie quickly turning to face the opposite direction.

"spike I know it's erl-twilight!" began twilight before rarity interrupts her. 'oh shoot bald' she thought before tossing a nearby blanket over her two patients.

"phhtt splendid*" let out rarity annoyed finding her and her sister in light darkness whilst her sister meeps.

"gauh twilight what happened is everything alright?" asked spike before he found himself with a scroll" "?"

to princess Luna please then go sit our something and dont eat any crystals there experimental" instructed twilight ignoring the drakes embarrassment.

"Oh um right-ffffwwrrph heh heheh I'll be over there," said Spike as he sent the scroll on its way quickly vacating the area.
