Alicorns pre-face and subject one:Luna

Author's Note

Below is the rough notes of Twilight into alicorns physiology they are unedited and unrefined. They will not be edited or proof read.

Alicorns pre-face and subject one:Luna

"These are the rough notes of Princess Twilight Sparkle, I am conducting a scientific study into the alicorns that feature in the collective works of Neokiva, a weird and eccentric unicorn mare and writer." Twilight started dictating.

"Hey! What is that supposed to mean, you make it sound like being weird and eccentric is a bad thing." Neokiva grumbled.

"Not necessarily bad, just descriptors." Twilight replied offhoofedly. "And weren't you the one who wanted to do this? Oh and thanks for funding this by the way." Twilight added.

"Yes, I did. So I had a unified theory of alicorns from my worlds so people can use this as a guide. you are also welcome." Neokiva agreed.

"Do we have to do this?" Luna griped

"I don't see why your complaining Luna, a lot of the studies are hooves on and fun." Neokiva continued

"We, for one art most concerned and self conscious, what will ponies say when they discover some of our secrets. What will 'Tia say." Luna asked.

"Princess Celestia was most enthusiastic and very receptive to it and about the deal I did to secure her participation I wonder why?" Neokiva interjected confusedly.

"What did you promise her?" Twilight asked eyeing Neokiva warily.

"I'll tell you later if I am able, oh and if you don't hear from me in five days come to canterlot castle and find me as I may need assistance and bring plenty of water as well as an ice pack I'm certain I'll need it." Neokiva trotted out. A few minutes later she picked up one of the bottles of lube, before rushing out again.

"Okay~ then let's get continue!" Twilight exclaimed.

"Along the way I shall interview subjects and produce evidence where possible or cite another source, peer reviewed by myself." Twilight dxplained

Today our subject is Princess Luna.

"Twilight art thou sure that we need to do this?" Luna grimaced as Twilight attached electrodes to her body.

"Yes we do for science!!!" Twilight gleefully exclaimed while Luna grumbled something under her breath.

"What was that dear?" Twilight asked sweetly with a smile on her face.

"Nothing sweety! I'm just so excited to help you with your experiment." Luna laughed nervously.

"Good, let's get started." Twilight said as she levitated a tape measure and a large plain dildo. Twilight then liberally slathered it in lubricant. Luna also found her levitated up to a ring with four hoof cuffs and locked Luna's legs in each. Twilight slipped a magic nullifying ring onto Luna's horn. The dildo floated behind Luna's body and sight, Luna felt a tugging on her tail as a foreign object prodded against Luna's backdoor and only had a second to brace as the offending object shot up in Twilight's magic. Luna grunted from the sudden intrusion, Twilight moved the dildo in angles subject Luna closed her eyes moaning ever so slightly.

Luna turned to Twilight and levelled a glare at her, "Having fun are you dear?" Luna asked Twilight.

"Of course!" Twilight replied cheerfully. Luna felt a pleasant pressure in her abused anus as the dildo moved and caressed the walls of her rectum. Luna felt a wave of pleasure going through her body a shiver up her spine as her cock made it's appearance soon after becoming turgidly erect.

"Subject Luna apparently has a penis whether or not it can impregnate mares has yet to be determined. Also to be determined is if she is a unique case among Alicorns."

"It's almost as if I'm a futanari or something." Luna commented dryly.

Twilight dived underneath Luna's testicals and looked up and sure enough she spotted Luna's drenched marehood winking. Twilight dragged her tongue along it sampling Luna's taste.

"Subject Luna is correct she is a futanari and she appears to be in heat."

"Mmmnn you taste like blueberries." Twilight moaned and licked her lips as Luna shuddered at the feeling of Twilight's tongue against her marehood. Twilight measured Luna's length with the tape.

"Oh my three feet of meat!" Twilight squealed with excitement.

"Now to prepare for a long term experiment." Twilight giggled as she spun around and lifted her tail revealing her own soaking wet winking marehood, causing Luna to strain at her restraints " Subject is reacting similar to how a stallion would, when a mare presents themselves during heat. " Twilight used her magic to part her lower lips backing up she took Luna's cock in her magic and guides the tip to her soaked nethers sliding it in as she backed into Luna who was trying to buck her hips forward to feel the rest of Twilight's vagina.

Giggling Twilight hilted on Luna's cock as she did Twilight gasped, feeling the tip flaring as it was prodding against her cirvix. Luna was gasping as her sensitive member rubbed along her mare's tight tunnel. Luna felt the warmth sliding up her cock gasping as good air hit it. Before she felt it re-enveloped
In Twilight's warmth, causing her to moan loudly and more frequently. Twilight rhythmically pumped up and down on Luna's shaft adding her own grunting and moaning to the o D's filling the room. Twilight pressed her back into Luna's barrel and leant her head back, Luna took advantage of her new position to lick Twilight's horn curling her long tongue around the spirals eliciting squeaks and moans from her, as Luna thrust into her tight pussy.

Twilight and Luna where both in Elysium as Luna took Twilight's horn into her mouth waves of pleasure crashed over their bodies as Luna felt a pressure building in her balls, "T-twilight I am almost there don't stop!" Twilight redoubled her efforts thrusting down harder as she tightened her marehood around Luna's rod, the two mare's moaning reaching a crescendo. Luna hilted as Twilight's marehood tightened her flared stallion hood it breached Twilight's cirvix cum rushed up her cock and pulsed as ropes of cum filled Twilight's womb with Luna's seed again and again with each pulse both mares screaming in ecstacy as they came.

"Experiment prep concluded, expected result, our own little foal." Twilight released Luna's restraints and the lunar princess finally wrapped her forehooves around Twilight as Twilight nuzzled her.

Subject two: Celestia. Gambling on Fertility aka Location of Neokiva.

Rough notes report 2: location of Neokiva,

After a few weeks had passed with no word from Neokiva, subject one: Luna and myself made our way towards Canterlot and Neokiva’s last known coordinates, the palace. Upon arriving at the palace, we discovered that it was currently day court. So I decided we should go inside the throne room and ask Celestia if she had seen Neokiva. What we saw when we entered was surprising to say the least, it was full of tailor’s, florists, bakers and some confused nobles. I even spotted Rarity who was currently measuring sompony on the dias.

We moved up the line and when we set our eyes on the pony being measured, It was Neokiva who had a sour expression on her face, sat on what looked like a donut, sitting next to a smug grinning Princess Celestia,

“Oh! Hi guys,” Neokiva addressed them perking up a bit,

“Have you come to rescue me from the hell that is dress fittings?” Neokiva begged,

“Don’t move darling, I need accurate measurements for your dress,” Rarity chided, as she marehandled Neokiva,

“No, Twilight was worried about you. It seems she needn’t have bothered, what is this all for anyway.” Luna asked gesturing to everypony.

“Oh, I lost a bet with Celestia. I wanted to test the potency of Celestia’s seed and she said ‘I can get any mare pregnant within two weeks’ I said ‘Prove it!’ she then bet she could get me pregnant within a couple of weeks and I foolishly took her up on the bet, saying ‘I will marry you and be your mare, if you manage to impregnate me within two weeks!’ turns out i was also in heat at the time and she was plenty eager to prove herself. So now I’m pregnant, can’t sit down without a donut and engaged to Celestia, stuck in this dress hell and i am planning on suing that company who made that lube,” Neokiva groused,

Rarity and the rest of the ponies in the room had matching blushes as they heard of Celestia’s and Neokiva’s implied escapades,

“Hang on, what would you have gotten if Celestia lost?” Twilight asked curiously

“It’s embarrassing,” Neokiva said her face coloring crimson red from the blush

Celestia spoke up getting everypony's attention, “She wanted to become an alicorn and have me weight on her forehoof and hindhoof, She might have to become an Alicorn anyway to survive what is to come, can’t have my mare dying on me and because she is pregnant she is getting her other wish too!” Celestia chuckled as neokiva’s blush deepened,

“Wait so if you’re getting your wish anyway, why are you complaining?” Twilight asked confusion in the tone of her voice.

“What part of needing a donut to sit down and sueing a lube production company don’t you get? Celestia was quite vigorous, I was afraid it’d split me in half!” Neokiva exclaimed and gained a faraway look as if seeing something utterly traumatic, “ I hope she hasn’t turned me into a size queen. Oh and before I forget here are my notes,”

Neokiva said wincing as she moved to give them to Twilight, whom began to look over the notes, her face turned redder and looked up to Celestia and then back to the data, and again to Celestia whose smug grin had returned in full force, before finally turning to Neokiva. “How in Tartarus are you not dead!?” Twilight exclaimed, Celestia’s grin widening further as Luna joined Neokiva in that thousand yard stare,

“I almost did, I think I had a near death experience, my grandmare and grandstallion were beckoning me towards a bright light along with my other deceased family members, and my dog Jessie. I woke up in the palace infirmary, apparently Celestia had them give me a pregnancy test while i was out, hence why I am here. Because I lost the bet, oh well I don’t really have an issue marrying ‘Tia, though I wish this dress fitting would be over so we can snuggle,” Neokiva explained, “Oh and it’s twins by the way.”

“Yay! I get to be an Ant,” Twilight giggled and pressed, her ear against Neokiva’s belly,

“That’s Aunt, Twilight.” Luna corrected with a good natured smile,

“Twilight, you won't be able to hear or feel the foals yet.” Celestia giggled at her ex-student,

“Oh! yeah right I forgot,” Twilight said blushing sheepishly in embarrassment,

“There and we are done Darling, you may return to your snuggling,” Rarity said her face still covered by a blush, to answer her Neokiva found herself donut included levitated under Celestia’s wing, and then Neokiva proceeded to snuggle up to Celestia.

“So I guess that makes us Sister-in-laws then, Neokiva?” Luna said,

“Yes it does,” came Neokiva’s muffled reply from Celestia’s side,

“Did you find anything else out in your experiments?” Twilight asked,

“Well, Alicorn horns and wings are more sensitive than a unicorn's horn or pegasus’ wings, though require arousal via other means, and ‘Tia really likes it when you mmmf!? Mmmmn.” Celestia interrupted Neokiva with a deep Prench kiss, Twilight could swear she could see something wiggling in Neokiva’s throat, but for her remaining sanity decided to ignore it and instead focus on their faces as they broke apart, Celestia and Neokiva’s tongues hung out of their open mouths, connected by a string of saliva. The sound of meat slapping against metal sounded through the air and feathers flying no doubt from the pegasi suffering from a bad case of wingboner caused Twilight to hide under Luna’s wing to hide her own embarrassing problem.

A scroll appeared in front of Celestia distracting the pair from turning this into a public exhibition,
Luna and Twilight leant over to look at the letter.

Dear Auntie Celestia,

I am nearing the end of my pregnancy, with a month left we would like to invite you, and Luna to my and Shining Armors, foal’s crystallizing, in a month's time.

“Eeee, I am Aunt two times over!” Twilight squealed,
