sweetie's punishment

"So what is this thing?" asked sweetie as she returnd from basments tiny batroom seeing twilight standing behind a wall of buttons, levers, lights, nobs switches and several screens built into it.

"It's a medical scanning array" answered twilight as she pressed a few buttons. "It basically gives me a three dimensional model of your sister's body but from the inside out" she finished as she looked over to sweetie. 'she's so curious it's adorable' she thought.

"Oh ...it's not going to hurt is it?" asked sweetie concerned as she looked at her sister seeming to squirm a little more frequently.

"Oh no she'll be fine she might actually enjoy it snicker" let out twilight trying to focus on the screens.

"I he-er-ard that mm auh how long entel-eel your done?" said rarity struggling to keep still as she felt her insides tingle and give an occasional clinch.

"Rarity?" questioned sweetie as she noticed a clear liquid pooling beneath her sister. 'did she just pee herself?' she pondered as she looked back to Twilight as she saw a screen show her sister's skeleton before changing to show different organs.

"Twilight?" let out sweetie concerned as she noticed a thicker substance ooze from beneath her sister adding to the mess wondering way her sister had wet herself.

"Its fine hey look here you see this" responded twilight trying to draw her students attention away from her friend's excitement.

"Is she huh what's that?" began sweetie before looking at the main monitor seeing something she couldn't see when she looked back at her oozing sister.

"Giggle it's your sister's aura or the magic that radiates her magic signature," said Twilight as she points to a form of Rarity with a mist surrounding her friend's digitally modeled body.

"What's an aura? Do I have one?" asked sweetie watching as a mist seemed to move like celestias mane in an abundance of colors the strongest being around her sister's heart, horn, and cutie mark.

"An aura is in simplest is the energy that radiates from an individual and yes you have one to oh and yours sister fine just a bit antsy hey check this out" explained Twilight finding her distraction to of worked. 'she a bit young to know just yet' she contemplated as she turned a nob causing the image to shift to show different parts of her friend's body.

"Uh? I don't get it so it's like our magic but why can't I see it when I look at her?" asked sweetie not understanding why she could see it with her own eyes.

"Oh, that's because it's an energy but you can learn to feel and recognize it um ah it's like leftover magic that surrounds's her uh like residue it's complicated" tried twilight as she explained something several grades above the fillies magic class. 'oh, why don't I teach you next time you come to practice your magic then I can teach you how to recognize your sister from other pony's with your acronychal senses" she finished seeing the confused look she was gaining as she tried to describe something above her students magic level.

"..." 'ok um so like uh?' thought sweetie confused as twilight talks over her head.

"Oh you know how-how uh oh um has your sister ever picked you up using her magic?" asked twilight trying one last time before she'd move on.

"Oh yeah, lots of times ...what does that have to do with it?" responded sweetie curiously.

"Oh ok great now have you ever felt how it seems to carry a certain feeling to it as it washes over you?" furthered twilight as she saw sweetie stick her tongue out in concentration. 'she's so cute an even cuter even without her fur' she thought as she waited for a response.

"Oh so like how I feel warm and fuzzy and safe, calm like that?" responds sweetie not sure she was getting it right. 'I always feel welcome and safe whenever she does' she finished in thought as she looked back to see her sister smile at her feeling warm by it as she smiles back.

"Yes something like that but more like this some even say they can feel a ponies emotions by reading there aura oh sweetie look at this where almost done" answered twilight as she found one of the layered three-dimensional models to have finished as she turned on nob and switch generating a 1/3 scale holographic representation.

"Gasp is ...is that her heart it's huge!" gasped sweetie in curious excitement as she sees a pony-shaped hologram of red and blue lines with a heart in its chest. "Twilight there's something wrong with it," said sweetie worriedly as she looked her sister's heart over watching as it moved in a continuous rhythm hearing twilight click something on followed by a continued beeping in sync with her sister's heart.

"What do you mean sweetie it looks healthy to me?" said Twilight as she used her hooves to pull two ends of the hologram making it bigger, curious and hoping she didn't miss anything.

"What do you mean! Twilight it's all wrong it's not shaped like a heart at all?" began sweetie confused as to why her sister's heart looked so strange. "Is there something wrong with her twiligmmnph" said, sweetie, before her mentor put a hoof in her mouth. 'please be ok!' she thought, getting frantic as she started to raise her voice waiting and hoping for good news only to hear giggles.

"Giggle she's fine sweetie every ponies heart looks like this even yours" began twilight as she smiled at her student's adorable miss assumption.

"Giggle he ha oh sweetie its alright darling I'm fine even twilights heart looks like that the heart your thinking of is well hey-y-ey why do they look so different?" assured Rarity curious as to where their difference came from.

"It has a lot to do with hearts and hooves day but more than that a long, long time ago it was illegal to cut into a pony's body due to religious sacredity so doctors and scientist back in those days had to make a guess as to what it looked like but after a while and several illegal studies of what is now commonly known as autopsy and anatomy we know it actually looks like this. sweetie this is a live representation of your sister's heart and its above average in size too" explains twilight as she took her hoof off of sweetie's mouth.

"Huh? So its, but why don't they make those hearts look like real hearts then?" inquires sweetie as she looked at her own chest feeling her heart calm down a little.

"Giggle same reason just that back then and since then its been a symbol of the heart but the actual heart looks like this ...hey rarity would it be ok if I gave your sister her own scan minis well you know?" finished twilight as she looked around the corner to see her friend had a face that told her she wasn't going to be able to answer but gets a nod yes-no-yes from her impaled friend non the less.

"So this is what it actually looks like ...cool I cant what to tell my friends!" chirped sweetie as her horn gave a green spark in her excitement.

"Giggle, ok sweetie, oh would you like to see your sisters stomach what did it look like in there if I might ask?" said twilight giggling unable to stand her students face and huge green eyes.

"I want to see everything eheh giggle um t was um well wrinkly soft and oddly warm mm..." let out sweetie eagerly before getting nervous at Twilights second question.

"You don't have to talk if you don't want to" assured twilight putting her hoof on sweeties wither getting an awkward smile in return. "Here can you tell me what this is?" asked Twilight as she swiped her hoof over the hologram causing a new one to take its place.

"Ooh um that's her lunges there huge not like I thought they'd be," said, sweetie, as she and her mentor began going over her sister's internal workings.
