Author's Note

Science Unfair takes place after Anon Saves the Day but before The Day Saves Anon.
This chapter brought to you by EnticingCanine as part of the Extra Chapter Challenge.

Twilight Sparkle is a mare of science. While she doesn't understand what has happened to Anon and Metamora, somepony has to make sure that the technical considerations around thousands of Changelings integrating into Equestrian society have been, well, considered. Good thing Pharynx is a willing test subject.

[Bonus][Act V] Science Unfair

“Hey,” you call into the seemingly empty library, “anyone there?”

“Pharynx?” Twilight’s voice called, scents of surprise and excitement wafting toward you from- “I’m downstairs! Come on down.”

You had some very interesting shared remembrances of that basement, courtesy of Metamora. Truth be told, you’d rather be helping with whatever the princesses were trying to do to bring her back. But you understood, presumably as did Twilight, that there was always a big picture. So you descended the stairs, trying to clear your head for the task ahead. If only you knew what that task was.

“Hi!” Twilight greeted you warmly as you reached the bottom of the stairwell, “I’m so glad you were able to make it.”

“I was told there was important research. I came as fast as I could.”

“Yes. The princesses asked me to do some testing to make sure that everything goes smoothly now that this is your home too.”

“Oh,” you sighed, “Have to make sure we’re actually reformed, right?”

“Nonono!” Twilight corrected, shaking her head vigorously, “Literally the exact opposite! I need to make sure that Equestria will be safe for every Changeling.”

“No offense, Twilight, but we’ve been in and out of Equestria for hundreds if not thousands of years with no trouble.”

“But you haven’t been given love during that time. We have to make sure-”

“Anon and Metamora are-” you stopped yourself, “…were fine. Why would this be any different?”

“Well we don’t know if pony love is any different. It might be harmful in large doses. We just… The princesses and I and… really everypony, we want to make sure we’re good hosts.”

“I understand. Please let me help however you need.”

“Thank you!” she squealed, “Thank you so much, Pharynx! You won’t regret it!”

“I’m certain I won’t,” you agreed wholeheartedly. Between what Metamora had shown you, and what you experienced with Cornflower, trust was a lot easier to come by now. You refocused from your brief reverie, “Now what do you need from me?”

“Well at this point I don’t have the resources to really clinically test this, so unfortunately we’ll have to be a bit crude in our experimentation?”

“Crude?” you asked, not catching her train of reasoning?

“Well I don’t exactly have stores of distilled love, nor do we have the time or subjects to test this reliably so…” Twilight paused, making sure you were following, “I’m just going to have to monitor you while I give you my love.”

“That doesn’t sound so bad,” you reassured, already looking forward to the free meal.

“I uh…” Twilight chuckled nervously, “…I’ve got no clue how to give love, you know scientifically.”

“Well what about un-scientifically?” you asked, posing the obvious question.

“Um, well I… We could but…” Twilight blushed, “I-If you promise to be gentle and…”

“Wait, you’re saying…” you tried to summarize, “sex is the only way you know to give love to a Changeling?”

“I’m sorry!” she exclaimed, hiding her face behind a hoof, “I’ve never been so unprepared for science in my entire life!”

“Twilight,” you called, trying to break her from her panic, “There are other ways to share love.”

“There are?”

“Of course,” you explained, “Sex is obviously the quickest, I mean there’s a reason it’s called making love. But it doesn’t have to be sex.”

“Then what?”

“Come lay down over here,” you motioned to a corner of the room where some cushions were laid out. As she obliged, you laid down next to her.

“Like this?” she asked, a nervousness in her voice and in the air around her.

“Yes, now…” you started, leaning gently into her, “Tell me about something that makes you happy.”

“I like sunrises,” Twilight offered, looking to you for approval, “they’re a beautiful phenomenon, and a nice reminder of who’s responsible for it.”

“Good,” you cooed, feeling the first wisps of her love starting to diffuse, “Tell me more.”

“Well, Princess Celestia was almost like a second mom to me,” Twilight continued, radiating the warmth of her appreciation, “I mean my parents were both great but she… Understood me?”

“But you like her,” you started following a hunch, “…more than family, right?”

“I-” she tried, her emotions turning sour for a brief moment, “Yes. And I had a chance to act on those feelings recently. It wasn’t what I expected.”

“Do you feel differently now?” you asked, trying to redirect her back to happy thoughts.

“Well I…” Twilight hesitated, “She needed more than I knew how to give.”

“I can relate,” you laughed.

“Oh, um… with, uh,” Twilight stammered, trying to remember her name, “…with Aphelion, right?”

“Yeah,” you confirmed sheepishly.

“Well she sure seems to like you already,” Twilight offered, “What’s missing?”

“She, uh,” you started, “She took so quickly to this love sharing thing and I want to show her that I’ve changed too, but it’s hard for me to, you know… I’m so used to hoarding love to survive.”

“You’re not hoarding it right now,” Twilight pointed out, her horn lighting and causing a red mist to precipitate out from the air, “I noticed it and I can’t even feel emotions. You must really like her.”

“I love her, Twilight,” you explained, “but I can’t just give her love, I need to feed too.”

“She needs more love than you can give her?” Twilight asked with concern in her voice.

“No,” you answered, “But she deserves more. I’ve seen how much love Anon gave to Metamora and I… If I could give her that much…”

“P-Pharynx are you…” she asked, staring towards your hind legs, “…aroused?”

“Wha-” you exclaimed, tracing her gaze right to…

“That’s…” Twilight giggled, “kind of adorable. Getting all excited about your crush, huh?”

“Twilight, I can taste emotions, including yours. You of all ponies don’t get to shame me about being horny right now.”

“Eep!” she squeaked, recoiling in shock as you laid her deception bare.

Somehow that only made you more excited.

“I-I…” she hesitated, “It’s probably just…”

“No excuses, Twilight,” you declared, “We both need to be honest. For Equestria.”

“Honest…” Twilight chewed on the thought, “If we’re being honest… I’m really pent up. It’s a long story but… I don’t want to pressure you into…”

“You didn’t want me to feel used, right?” you asked. Twilight nodded in response, “Well maybe I want to be. Maybe I want to be useful for once instead of…”

“Pharynx,” Twilight sighed, “you don’t have to prove anything. Not to me, not to Aphelion, not to anypony.”

“What would you know?” you asked, cringing at your own words, “I’m sorry, it’s not your fault.”

“You’re right,” Twilight answered, leaning against you a little more forcefully, “There’s a lot I don’t understand about love, about Changelings… But if there’s one thing I know, it’s that hands on learning always works best.”

“Twilight,” you warned, watching her bring her muzzle to yours. Before you could discourage her further, she planted her lips on yours, enveloping you in warm, filling pony love.

“Come on,” Twilight encouraged, “Let’s make love, Pharynx.”

“I thought you didn’t want to…”

“So did I,” Twilight explained, pushing you over onto your back and rolling atop you, “But you… consider this a donation, so you can make her happy.”

“Twilight,” you gasped, “I don’t know what to say.”

“You don’t have to say anything,” she whispered, her breath hot in your ear, “unless you can’t help yourself.”

Fuck.

She rolled her hips, moving ever so slightly forward with each motion, the warmth between her legs drawing ever closer to the sensitive tip of your shaft.

“It might come as a surprise,” Twilight started, “but I’ve never been with a Changeling before.”

“Oh? Liking what you see?”

“Yesss,” she moaned, finally lining up the tip of your dick with her wet marehood, “Are you?”

“Changelings are less about what we see, and more about what we feel,” you explained, nipping gently at her neck, “but getting both in one package is nice.”

“Oh!” she squealed, finally feeling you start to spread her open, “such a gentlecolt!”

“You did ask me to be gentle,” you explained, softly pressing yourself further into her with a need you didn’t know you had.

“W-What if I changed my mind about that part?” Twilight asked, pushing back more forcefully until her hips met yours.

“Then I’d have to oblige,” you said, wrapping your forehooves around her back as you slowly retreated.

You could tell she was ready for it, her head lowered, her lips inches from yours, her marehood pulsing around your shaft. So you didn’t hold back. Sex was the most effective way to gather love, and thousands of years of evolution had honed your species into machines built for maximum carnal efficiency.

“Oh fuck!” she squealed, shuddering as you shoved yourself back inside with one quick thrust.

“How does it feel, Twilight?”

“Y-youuu-” she groaned, half in pleasure over your change in tactic, half in contempt over your effective strategy.

“That good, huh?” you chuckled, pulling out with an agonizing slowness but ramming yourself back in like your life depended on it.

“Come on,” she grunted, lowering her head a little more, “that all you got?”

It wasn’t. You switched it up once more, instead of long, staccato thrusts you switched to a short, rapid motion. Her ragged breath switched instantly to small moans of pleasure. She tried to match your thrusts with her hips, but all she managed was a weak shudder.

Just when you thought you had finally secured the upper hoof from underneath, you were surprised once more. Her forelegs, which had been supporting her ever so slightly, finally gave, causing her to fall fully onto you and causing her horn to cross with yours. Immediately you felt a jolt through you, as if her horn had completed a circuit. Eventually, though the sharp surprise of her magical infusion dulled and instead of knocking you off kilter, it drove you on even faster.

“Oh Pharynx!” she squealed, “…s-sorry I-”

“Keep going” you demanded, feeling her magic resonate through you as you felt your magical energy start to intertwine with her body. Your magical embrace fed you back as much pleasure as your physical union, mirroring what the other felt and relaying it back to one another.

“H-hive, Twilight!” you grunted, “I’m gonna-”

“Hah, m-me too!”

Your dueling symphonies reached their crescendo in synchrony, a beautiful harmony.

“That was …highly informative,” Twilight agreed, rolling off of you, “T-thank you for being such a v-virile… I mean valuable test subject.”

“Well,” you grinned, “Anything to save Equestria.”

You moved to leave, having accomplished more than either of you had expected. As you turned to face the stairs up to the library proper, you noticed something, or rather someone…

“Pharynx did you really not invite me?” Aphelion asked incredulously, standing at the foot of what were turning out to be a rather unfortunate set of stairs.

“This all kind of… Just happened. You know I love you first and foremost, my little nymph.”

“I’m not a little nymph!” she whined, “And you completely glossed over the possibility of a really hot threesome! I’m more disappointed for you than I am that I missed out.”

“That’s my bug,” you cheered, “What do you say, Twilight? Room for one more?”

Twilight was in shock, scribbling furiously at a clipboard in front of her.

“Not this again…” Twilight called nervously, her horn lighting, “I have to go.”

“Looks like it’s just you and me, bug,” you smirked, already feeling yourself getting ready to go again, “Why don’t I make it up to you?”

“Oh Pharynx, how’d you know?” Aphelion gushed, “I’d love to go for ice cream!”

“Ice cream?” you asked incredulously. This was not what you had in mind.

“Yeah!” she squealed, “I’ve been longing for something thick and creamy to fill my mouth with all day long!”

Hive did you love her, but she was going to be the death of you.
