The New Normal

Night Light screwed up his face in weary admonishment as he twirled a straw through the ice of his daiquiri. "You're both adults. You're Prince of the Crystal Empire. She's the ruler of all Equestria. We're just your parents. This is completely between you and her. We've only had soft power over you for quite some time now; the most devastating weapons in our toolbox are your mother's guilt trips and ISDIY."

"What's ISDIY?" shrugged Shining in puzzlement.

"I'm so disappointed in you," he clarified, before taking a sip.

Shining's face wilted and he clutched his chest with one hoof as he recalled the phrase that left few but deep score marks in his foalhood. "That feels really bad."

"I know," nodded his dad. "You only pull that one out for special occasions; you don't want to overplay it. Don't tell me you've made it this far as a parent and never used ISDIY."

Shining sighed in frustration as he seemed unable to get a straight answer from either of his parents. "Did you already talk with Twili about this?" he mumbled.

"Yes," replied Velvet from under her sun hat. "We told her the same thing. We really don't need to know and we're taking a stance of passive opposition."

"You don't need our approval," added Night.

"I know but… I want it. I always want it."

The elderly couple side-eyed one another with a frown of sad but unwavering resignation.

"Shining… just do whatever you're going to do," replied Night with finality.

Dad's stern evasiveness on the matter told him it was time to stop pushing. He was trying to give his son an out so he could slink away and save face. Everyone's decisions were already set in stone so there was no point in further discussion. His parents shaking their heads over their drinks was as close to acceptance as he was going to get.

"We will still love both of you," added Velvet trying to honeycoat her husband's words as she'd always done.

"Thanks," he sighed at their offered consolation. Jeez, he was just trying to give his sister a foal, not get a face tattoo. No wonder they never told them about this. - - -

Early in the evening of the Sparkles' last day in the Crystal Empire, Shining Armor knocked on his sister's door. It seemingly opened itself for him under the influence of her magic. He entered to find her hunched over a writing desk. She dropped her pen and turned with a warm smile.

"Hey."

"Hey," he parroted, closing the door behind him. He wandered up behind her and she tilted her head back to look at him upside down.

"You still wanna go through with this," he murmured. "Even after all the drama?"

She glanced to the side, then back at him, her eyes gleaming with unwavering resolution. "Yeah, why? Are you getting cold hooves?"

Shining shook his head. "No. I'm here for you, Twili."

She smiled again. "Thanks. The most important thing is that you and Cadance are okay with it." Part of her desperately wanted to know if his feelings about her had changed in thirty some years but they'd never been so direct about their desires.

"Alright… So what do you want to do? It's your show." It had always been her show, or so they said.

"You remember what we used to do… a long time ago?"

Shining thought. There were a hoofful of things he could come up with but only one jumped clearly to the forefront of his mind. One thing she used to love above everything else. "You wanna sit in my lap?"

"Yeah," she blushed, a little embarrassed by her foalish sounding request.

Shining squinted back at her suspiciously. "Is that a good position for conception?"

No, it wasn't. Even Shining could see that. She was immediately reminded of how Cadance had seen right through her at the arrival dinner. Yes she wanted an heir and yes her brother's cells were objectively the best option for producing the results she wanted but was it a crime to just enjoy the journey with him?

"Shut up and get in the exam chair," she smirked.

"Oh, I see." Shining smiled and turned away to go sit on the couch. The less questions he asked, the easier things were. That was always how it had been in their sexual relationship. Twilight made the rules and he was just along for the ride.

She teleported to her hooves and approached him, trying mentally to settle her jitters. It wasn't so much about her own performance as it was about wanting her brother to be caring and receptive to her just like she remembered.

Twilight reared up, setting her forehooves on the backrest, either side of Shining's neck. She closed her eyes, tilted her head and leaned in softly. It felt natural and the fireworks on their lips ignited immediately. It was almost like… a first kiss.

Her forehooves curled around the back of his neck to stroke his graying mane as their kiss deepened. Shining's own hooves braced above her hips. He groaned as their lips battled. Now that Twilight had found that the water was warm, she intensified her assault. Her tongue dipped into his mouth. She moaned louder than she thought she would when he returned the gesture. Every touch, every wet graze and caress thrilled her and sent her heart soaring. She sucked up his tongue, chewing on it for a time as Shining's hot panting blasted her muzzle.

Twilight finally opened her eyes when she felt something poke her in the stomach. She pulled away and looked down to see her brother's member all fattened up and standing tall. He was ready for her and she was ready for him before they even touched but they shouldn't rush.

This was the last time. For right now, in this room they could do whatever they wanted together and she wasn't ready to let this incredible moment melt away yet. Twilight looked from his inviting flare back to his eyes. She lunged back in, recapturing his lips with renewed vigor in a bid to get all she could before her biological urges finally won out.

She tilted her head to the side and pulled his face into her neck in a wordless command to tease her. She sighed as he showered her with little wet kisses and nibbles leaving her spine tingling and cowlicks in her neck fur. She smiled in delight but felt the calling of her aching marehood.

Twilight pulled away from him again, returning to all fours. She began to stroke his cock with one hoof as she mulled over the best way to do what she wanted. Things would have to be a little different this time around. "Okay," she breathed with anticipation. "Ready? Here I come."

Twilight spun in a half circle, pointing her rump at his lap. Then she flagged her tail to the side and glanced behind herself as she backed up slowly.

Reading her movements, Shining pushed his skyward length down with one hoof till it was lined up with his sister's approaching pussy. She gasped as her drenched lips kissed his tip but she did not slow her approach. Shining watched with breathless awe as his sister's beautiful pink curtains parted over his flare and delicately contoured around his girth.

Twilight felt Shining's medial ring slip inside her. Then suddenly a pair of burly forelegs wrapped around her midsection and yanked her back, rump first into Shining's lap. They pulled her into an upright spoon against her brother's barrel with his muzzle peeking just barely over her shoulder.

"Ahh," she giggled.

"Oof," he laughed, as her sudden weight squeezed the air from his lungs. "Have you grown since last time?"

"Maybe a little."

"Wait, you're a full figured princess," he chortled. "What happened to my little sister?"

Twilight sniggered, trying in futility to contain herself. She felt her brother's chest spasm in laughter and she could no longer hold it in. They broke into a fit of hysterics even as she sat fully penetrated on his lap.

She exhaled, trying to reset. "Okay, okay."

Shining forced himself to stop laughing and instead focused on the pleasantly warm, wet squeeze on his length. Twilight swiveled her hips to settle herself around his base and the two of them just sat there for a moment breathing in the magic of an intimate embrace they hadn't shared for unknown years. No, they knew if they just did the math. It was when he started dating Cadance and it was Twilight's idea. She willingly gave up her test subject and special bonding time out of deep respect for Cadance.

Back when they used to do this, she remembered him towering over her. She'd reach her hoof up behind her head to caress his cheek while he bounced her on his cock. Though he was still a colt himself at the time, his body felt so big and powerful. It was a gentle strength she had yet to experience anywhere else.

Twilight made the first move, rolling her hips in a scooping motion and eliciting a quiet groan from her brother. He responded, clutching her to his barrel and reclining the both of them a bit in the seat. The slight angle allowed him to brace her above his lap, giving him just enough room to pump his own hips. He started out by squeezing himself all the way inside her in a slow but powerful push that served as a tantalizing appetizer for the rest of their visit.

Twilight hummed in approval as Shining began and their inner thighs clapped together quietly. Despite their initial awkwardness in the position, their rhythm coalesced elegantly. Twilight began to pant softly as their synergy reached full sync. She closed her eyes and let his touch stir a downpour of memories. - - -

"Are you sure about this, Twili?" asked the colt as he gazed anxiously out the window above the front door. "Mom and dad left me in charge, which means they're not going to be gone for very long… and I don't think they'd want us doing anything like this."

"It's fine, Shining," she assured him, floating a set of glass slides down next to the petri dish on her lab table. "It's just… scientific research. There's nothing wrong with it." Her assertion was at least partially true. What was curiosity anyway but unformatted research?

"Right," he nodded slowly. "But we're still not going to tell them… Right?"

Twilight bit her lip apprehensively. "Correct."

They decided to end the discussion there and not scrutinize their own reasoning any further lest they begin to poke more holes in it. Their whole internal alibi hinged on the mutually disingenuous pretext of producing a sperm sample for Twilight to examine… to learn. Shining wanted to help his sister but also desperately wanted to experience the touch of a filly, despite it being one of relation who was half his age. Twilight was interested in seeing live sperm cells under a microscope but also really wanted to see how dicks worked.

Shining had been extracting his own samples by himself for almost a couple of years now but it was better for their self rationalization if he just didn't mention that as a perfectly viable but much less educational option. Their list of unexpressed ulterior goals had each of them wondering if they were ultimately just taking advantage of the other.

"Okay, have a seat in the chair." Twilight pointed to the infamous 'exam chair' as it would come to be known. It was a cushy old plaid mustard yellow armchair where they'd ultimately have a majority of their first sexual experiences under the guise of dozens of tests. In the beginning, if it was happening in the exam chair, it was a 'test.' Later, the 'testing area' would be expanded to both of their bedrooms and the upstairs bathroom.

Shining sat down with a creak and exhaled with nervousness. Twilight tossed her clipboard on the lab table and hurried up to the gap between his hind legs. Her eyes trailed down to his genitals and his empty sheath.

"What's the best way for you to quickly achieve sexual arousal?" posed the filly curtly.

Being alone with a dirty mag and not being watched like I'm on a stage, for one, he wanted to say. He blushed. "I- I dunno. I think maybe kissing would probably work." He hadn't personally done it much but the times he had did send blood rushing expediently to all the right places.

Twilight groaned doubtfully. "Well, I don't know much at all about that but I'll give it a try… for science." She climbed up into his lap and reared up against his chest to reach. With their faces suddenly at the same level and so close, they hesitated in surprise. The two foals blushed as Twilight inched ever so closer to him.

She blinked and pressed her mouth to his and for a moment their hearts stopped from the sensuous electricity they'd created. Her lips were so soft and timid. His were bigger but so gentle and patient.

Twilight sighed delicately as her eyes fluttered shut and she slowly mouthed against him, seeking direction, his saliva slowly wetting her muzzle. Shining moved around, nibbling her top lip and then her bottom lip. Her little hooves pawed lazily at his chest as if begging for more. They were so cautious but it was no less exhilarating. Time had stopped even as their hearts thrummed loudly in their heads.

I'm kissing my little sister on the lips but it still feels amazing. Shining regained his self awareness to notice that his loins had tightened uncomfortably. That was fast.

"Twili," he breathed. "I think I'm ready; we should hurry."

Her eyes shot open in surprise as if she'd been yanked out of a trance. "Oh, uh, okay."

She hopped back down to the floor, almost tripping over her brother's hard on. She did an about face and stared at his stiff cock as it stood vertically above his plump pair of balls, waiting for her attention. She paused for her thoughts to emerge from the fog of a dizzying kind of head rush she'd never experienced before but would like to continue.

Twilight grabbed his engorged member with her magical aura, unable to resist pivoting it around for a quick examination. She'd never been able to see one up close like this before and it was a shame they didn't have more time but there could be other opportunities in the future. No, there would be other opportunities. She'd see to it as long as he was game.

Her eyes began to get lost in the interplay of pink and black speckles and the multitude of veins, ridges and other fascinating tactile features that begged to be explored. She shook her head, trying to get back on track. The light of her horn died but her forehooves quickly picked up where her magic left off.

Shining sucked air as she grabbed him by the medial ring and gave him a down up stroke. Nopony had ever touched him like this before. It made his stomach quiver.

Twilight looked him in the eye uneasily as she continued to pump him like a butter churn. "I admit I couldn't find many books actually detailing this part of the process but one thing they seemed to agree on is achieving a certain threshold of stimulation to the genitals. I'm guessing if I just do this for long enough, it should cause you to orgasm."

"Yeah, I think you're right," grunted Shining.

"Tell me if you feel like you're about to ejaculate so I can catch the sample."

"Okay," nodded Shining.

The two of them sat there silently as she worked his length with the steady beat of a ticking clock. Shining grunted softly and balled his hooves on the armrests as slowly but surely a certain familiar energy began to coil up between his legs.

She used a gentler, slower touch than he used on himself. It felt good and he would certainly cum from it if she kept it up but he also worried about taking too long and he also wondered…

Shining swallowed. "Um, Twili, I have an idea about how we can probably speed this up."

She cocked her head curiously to one side as she continued to jerk him off. "Really? How?"

"Use your mouth to stimulate me."

Her brow furrowed with uncertainty. "Y-you mean more kissing?"

"No, I mean do what you're doing now but with your mouth."

Twilight watched her own hooves firmly running along his length until the idea finally dinged in her brain and she imagined her head bobbing up and down as she massaged him with her parted lips. "Oh," she blinked. Seemed kind of weird but her instincts told her he was onto something.

Twilight paused her strokes and stood on her hind legs so she was eye level with his meaty tip. Without much deliberation, she pulled the shaft to her with one hoof, opened her jaws and stuffed her brother's head as deep into her mouth as she was comfortable with.

The hot, wet embrace within his sister's lips immediately turned the colt's body to jelly. The first thing Twilight noticed aside from the wide girth was the edge of his flare and how interesting it felt on her tongue and the roof of her mouth.

Her eyes flicked up at him and she was struck by the feverish glaze of his slack jawed expression. "Like this?" she mumbled, her slurred words buzzing through his shaft.

"Y-yeah," he shuddered. "Feels like that's working pretty well."

Encouraged by his positive reaction Twilight began to pump her head, sucking and slurping loudly up and down his cock, mimicking the motions of her hooves. Her tongue undulated autonomously along her brother's underside, making him squirm even more.

A cascade of drool flooded down his shaft. It was messy, it was awkward but watching her fumble around on his dick, making it up as she went along was the zenith of visual arousal. He was getting a blowjob from his little sister and it felt amazing. His pleasure bucket had nearly filled up with drips from her strokes but her mouth hitting him at this moment was adding a pounding waterfall. Before he knew it, his orgasm was crashing through the door without a knock.

Twilight reflexively swallowed the first blast of hot saltiness. She spit out the second, having the presence of mind to catch most of it in her hoof while the third and fourth blasts landed on her muzzle and in her mane. It was so much faster and more powerful than she'd anticipated.

"Shining," she coughed. "You were supposed to warn me." She kept her tongue hanging out as more of his semen dripped down from the tip in a long sticky strand to join the puddle she held.

"S-sorry. I lost my focus; it felt really good."

She looked down curiously at the pearly white pool in her hoof, then back up at him. "It's fine. Just help me try to salvage some samples with-"

Suddenly they heard the front door latch open and the whine of its creaky hinges and their parents entering the house in mid conversation with a third unidentified voice. Their eyes bulged in horror.

"Abort! Abort the test!" Twilight spun in a panicked circle, still holding the cum aloft in her hoof.

Shining sprang out of the chair, casting off a glob of residual jizz from his deflating cock as he landed.

"Twilight," called her mother. "We invited your teacher, Ms. Flora over for a visit, come down and say hi."

"Go down and tell them I'm in the bathroom," she whispered urgently. - - -

Twilight cried out in rapture, caught in the skillful grip of her older brother.

Shining administered a dizzying hoofjob with one hoof while locking her body to his with the other. He maintained a steady beat of powerful thrusts, keeping her clit nearly vibrating with the edge of his twitching hoof.

Shining's humid labored breath poured over her shoulder. Her hind legs twitched out of her control as she surrendered her body to his will. The test was officially running her and she didn't care. She wasn't going to last much longer and in the back of her mind was aware it would be best for conception if she climaxed after insemination but there was no way she was going to tell Shining to lay off now. She could always get herself off again later.

Shining continued feeding her roaring fire as she drowned out their soft plap plap with a rising tide of unprincess-like screams.

Twilight's muscles locked up. She whimpered pitifully as she cleared the final hurdle and euphoria crashed over her. When her legs finally stopped twitching and she returned to her senses, both of her brother's forelegs were wrapped firmly around her but his thrusting had only intensified. The plap plap was back with a vengeance.

Catching her breath, Twilight slipped an encouraging hoof over her shoulder to stroke his cheek as he grunted on the verge. His muscles tensed and rumbled beneath her. She glanced down her body to see her brother's balls clenching and the underside of his base pulsing rhythmically as it pumped her full of his virile seed.

Twilight sank into him as he relaxed. She placed a hoof on his and smiled to herself. "You always did know how to make an experiment more fun."

Shining, for once, said nothing, only buried his muzzle in her mane and inhaled. They sat there, breathing softly, enjoying each others' warmth. They made no attempt to move because the moment they parted from the dreamy haze of their post orgasm embrace, it was over. They went back to their respectable public lives and were just good friends again.

Twilight put her free hoof on his cheek again. "Back in the very beginning when we first started doing those tests in the chair… you weren't just humoring me because you wanted to be helpful, right?"

"I was a horny middle schooler, Twili. I definitely saw some fringe benefits and wanted in… but I would have helped you anyway."

"I knew it," she smirked. "Well, I was genuinely curious about male anatomy in the most innocent way possible. It just became less and less innocent the longer it went on."

"And yet we still pretend is was about research."

"It was always about research," she gasped in put-on indignation. "It just wasn't only about research… and sometimes the research was just sex."

He laughed weakly as he let her sit forward. His softening length slipped from inside her as she stood up. Before he knew it, she was wiggling a glass vial in front of his face.

"May I?

Shining blinked in bewilderment before remembering how their encounters always used to end. "Oh, yeah."

Twilight floated the test tube to her brother's wilting flare. Then she used her magic to milk his soft length, carefully squeezing the last of his sperm into the receptacle. She stoppered the vial and whisked it away into an enchanted cold container to take home.

Shining got back on his hooves and watched as his sister put her cheek to the floor and stuck her ass straight up as high as it would go.

"What are you doing?" he laughed in amusement.

She turned to him without changing her odd posture. "I'm giving your guys a little help on their way to the goal."

"Oh." He scratched his chin as it dawned on him only now just how strange and momentous this was. He was siring a foal with his sister who he'd likely have no claim to and never play a part in raising. Only his family knew this. Would the foal know some day? He'd have three children who were here long after he was gone. It gave him a weird existential pause.

Twilight stood up again. "Thanks, BBBFF! This is the greatest gift you could have ever given me." She wrapped her forelegs around her brother as a tear formed in her eye.

He returned her hug. "Don't thank me. Thank Cadance."

"I really should somehow," she agreed.

"And don't cry. You're not even pregnant yet."

"I know, it's just very emotional for me for a lot of reasons."

"Yeah," he breathed. - - -

Cadance broke from her book to gaze out the window as the sun set the sky ablaze for its curtain call of the day. She didn't make it another two sentences before a sudden snap of magic interrupted her reading. She looked over the brim of her book to see Twilight smiling tentatively at her.

"Hi, Twilight. Shining put a bun in your oven, yet?"

Twilight blushed at her blunt but innocuous quip. "Well, conception can take a couple of days so we'll see.

Cadance snapped her book shut and set it down next to her steaming teacup. She was so well composed now compared to the first night, thought Twilight.

"Did you start that book I gave you?" she asked, lifting her cup to her lips.

"Oh, yeah. It's just creepy weird so far. I want to save it for the train back though so I'm pacing myself."

"It gets really weird," added Cadance emphatically. "You'll see."

Twilight smiled. "Um… Cadance, are things any better?"

Cadance looked out the window again and chewed her lip. "I… think so."

"I know this is all very unorthodox and by all means, you didn't have to agree to it. I can't express how grateful I am that you gave me this opportunity. I really want to repay you but I'm not sure how."

Cadance sighed. She stood up and drew her fellow princess into a hug. "You are right, it is unorthodox. I said a lot of… unorthodox stuff when I was drunk and it's still bubbling up in my brain but… I stand by everything. All of that was really inside me. I just never had the courage or insanity to voice it and even though it was painful and embarrassing, I actually want to believe things might start to get better for us now."

Cadance release her and shook her head. "You don't have to do anything for me. If I really wanted something out of it, I would have negotiated a better deal, drunk as I was. But can I ask you a personal question?"

"Yes," she answered without hesitation.

"How long have you and Shining been doing this?" She swallowed, bracing for Twilight's honesty to slap her across the face.

"Well, we started when we were seven and thirteen." Twilight felt sudden panic at how weird that fact sounded out loud.

Cadance's eyebrows shot up.

"We stopped when you started dating and I was fifteen."

"Seven?" she hissed in disbelief. "You were practically a baby."

Twilight smiled sheepishly. "I was very precocious for my age as you remember and in all honesty, the whole thing was my idea. I wasn't sexually mature yet but I was still very curious about that kind of stuff and well… my brother was the safe way to explore that area because I knew he'd do anything to help me and wouldn't get me in trouble or make me feel like a freak."

Cadance knitted her brow in intense thought. She respected Twilight as a pony and a ruler. It was difficult to come to terms with this revelation. She'd never look at her the same again but… what did it really change? Celestia's protege and ruler of Equestria had been fucking her brother since the age of seven and carried on doing it though the majority of her formative years. It wasn't just her formative years though, it was also Shining's. That was where he got it from. It put a lot of things in perspective as she began to draw comparisons between what he'd done then and what he was doing now.

It was strange, maybe just a fruit of cockeyed optimism but Shining growing up with a relationship like this and then leaving it to choose her over his sister and then Remedy and Twilight's uncanny similarities gave her hope for her granddaughter's future.

Twilight sat down across from Cadance. She looked out at the orange sun as it began to dip behind an icy purple mountain range in the far off distance. "I know he's not exactly the brightest pony but I also know he's always trying to do the best for those he cares about."

That was true, Cadance admitted to herself. Both of those things were true.
