A Shining Sparkle of Love

The first thing that Twilight did after walking into her room was to make sure the door had its heavy brass bar wedged firmly into the groove. Having done that, all that remained was to ensure that nopony could get in. She concentrated her mind on the protective spell she’d cast so many times before that the magic from her horn surged out almost effortlessly as if it were mere sparks of telekinesis, despite the intricate nature of the conjuration that would fatigue even the most powerful of unicorns. Waves of violet light rushed in all directions from Twilight, clinging to the walls, ceiling, and floor until the crystal room became a cage of a pulsating purple essence, harder than diamond, its molecular structure preventing any magic from slipping in and any sound from escaping out.

Twilight extinguished her horn with a satisfied smirk and stretched out, pushing her ass up into the air and allowing herself to truly relax for the first time since morning. Her pussy winked, bringing up a droplet of her juices that glided down her clit until it reached the bottom of her vulva and, with nothing to cling to, dripped down onto the sparkling floor. Twilight did her best to ignore the tickling sensation between her hind legs and began to slowly walk toward the bed, her tail swinging to and fro seemingly on its own.

Smiling like a naughty filly, she climbed onto the bed and crawled along on her belly to the other side until her muzzle was mere inches away from the nightstand, a complex piece of furniture with sturdy crystal frames and a set of magic locks installed in it. With a flicker and spark from her horn, the locks gave in and the only drawer box slid its way out of the nightstand. Twilight’s heart filled with excitement as the box’s content came into her view. And though she’d observed the object inside the box so many times that she could recall every little detail of it should she be awoken in the middle of the night, the experience was always enthralling and each time felt as if it were the first time in her life.

“Hello, brother,” Twilight whispered, leaning in to take the replica of Shining Armor’s cock into her hooves, a stars and shield Cutie Mark etched in its base. The whole thing was as huge and gorgeous as she’d seen it in the flesh, years back when she and Shining Armor shared the same home in Canterlot. The events of one particular night always arose in her mind whenever she took it – her brother running his hooves up and down along the length of his shaft, confident that the door to his room was closed and nopony could see him, his eyes squeezed at the impending surge of pleasure. And Twilight, sprawled out in the hallway, peeking in through the ajar door, her left hoof stuffed in her mouth to stifle moans of delight as her right hoof found its place between her hind legs, her pussy spasming and clutching at the intruder, her eyes fixed on Shining Armor’s throbbing cock, making her mind believe that it was her brother who was fucking her and not her own hoof.

She let out a pitched squeak into her hoof, almost revealing herself as her brother’s cock made the last powerful throb and a jet of cum burst out of his tip, painting a high white arc in the air and landing down onto his chest and belly. Something snapped inside Twilight then and a whole new set of sensations surged through her body, her clit spasming vigorously and her juices squirting out onto her tail and butthole as the feeling of pure bliss overwhelmed her whole being. She had read about sex and orgasm before of course – the entire castle library had been at her disposal since she’d become Celestia’s personal student. But she could have never imagined that orgasm might feel so good, so right despite the fact that the stallion she was clopping to was her own brother.

Bringing herself back from the long-past events to the present time, Twilight brought the artificial phallus to her lips and planted a kiss on the flat tip. She couldn’t live by memories alone, however beautiful and sweet. Her mind and body demanded a more material approach.

“I’ve missed you so much, big brother.” Twilight began to glide her hooves over the flare, gauging its shape and feeling every bump and ridge encircling the tip. She moved down along the phallus' length and squeezed it slightly, making the frogs of her hooves rub against every little vein along the shaft, the curves as close to the original as possible.

It had cost her a fortune to make a replica of her brother’s cock so accurate. More than that, it’d taken her a long while to polish it to perfection, the only possibility of having inside her anything different from her brother’s form making her stomach clench. She hadn’t had the luxury to get a real imprint of Shining Armor’s erection and a scatter of glimpses had been all she had to work with. Many nights had been spent to solve that puzzle and place all the pieces of the mosaic in her mind’s eye into the final, total picture in real life. But in the end, the result had exceeded all expectations and her brother’s cock had served her well for many years, and this night wasn’t going to be an exception.

“I’m sorry I couldn’t come earlier. There was a lot of work to do today.” Twilight brushed the medial ring and continued down to stroke the balls, a part of the implement she’d been racking her brain with for the longest time. She had to re-study the anatomy book to make the balls look and feel like a part of a real stallion. Unlike a manufactured model which had two hemisphere pieces of plastic simply glued to the base of the cock, the ballsack of Twilight’s creation hung off the shaft and had its own creases where it was connected to the sheath, as well as a pair of special egg-shaped implants imitating the curvature of testicles. And yet despite its complexity, the whole structure paled beside the synthetic skin that covered the whole thing and that had become the apex of Twilight’s craft genius.

“I know how I can make up for my delay, big brother.” Twilight assumed a sultry look as she opened her mouth wide, her tongue trailing a loop over her lips before it stretched away in the direction of her chin, providing an unhindered way to her mouth. Not wasting a second, Twilight threw her head back and slid the wide tip of the artificial cock along her tongue until she had it prodding at the entrance of her throat. Suppressing the urge to gag, Twilight wrapped her right hoof around the base of the cock and pushed in hard with one thrust, her throat contracting and stretching around the girth with a wet gurgling sound as the first beads of tears began to accumulate in her eyes.

Twilight ignored her body’s earnest protests at a foreign object cutting off its supply of oxygen and pushed the cock in further still. She choked hard as the medial ring stretched her throat even further, her instincts almost making her hoof pull the cock out. She managed to collect herself, however, and drove the cock deeper, making the last inches of the whole length disappear inside her completely with only the balls jutting out from the warmness of her mouth and instead pushing down against her snout, their enormousness preventing the air from getting into her nostrils as successfully as the shaft wedged in her throat blocked every breath Twilight’s body tried to draw despite her better judgment.

With her brother’s cock sculpting the outline of her neck, Twilight took a few seconds to accommodate to her position. Despite how many times she’d practiced deepthroating with her brother’s cock, Shining Armor was a very endowed stallion and Twilight’s tight orifice could only take him for so long. Twilight knew that she hadn’t that much time left before she would begin to suffocate.

Twilight took her hooves away from the cock, put them down on the bed and straightened her forelegs along her body. She did her best to relax, her brother’s cock still buried deep inside her throat. She closed her eyes and slowed the inner working of her body, preserving as much of precious oxygen in her lungs as possible. Then, in a state similar to that of pure serenity, her horn lit up and the cock in her throat began to move back and forth under the influence of her magic.

In her mind, Twilight conjured up the images of her brother, trying to bring up the most intimate moments they’d been through together – reading a good book at night while cuddling each other under the blankets, all the while their parents thinking that their kids had long ago fallen asleep. Or the time when she’d failed Celestia’s test and been bawling her eyes out into her cushion until her brother had sat next to her, patting her head. He’d always known what to say and how to comfort her when she felt bad, even when her parents failed at that. But more often than not, Twilight would just get nostalgic about carefree times whether it was she and Shining playing hide-and-seek in the courtyard or splashing water at each other in the bath when they were foals. Whatever memory sprung in Twilight’s mind eye, it had never crossed the line of sibling attachment and yet it was always more than enough to evoke the most primal desires deep inside her core when lying in bed alone at night.

With one powerful thrust Twilight’s magic slammed her brother’s cock back deep into her spasming throat, the impulse so sudden as to make her eyes water. Twilight didn’t complain and allowed her brother to use her as he wished so – rough and without any constraints, ethical or otherwise, with nopony to judge their deep bond.

Moaning around the cock, Twilight felt the heat between her legs rise to a blaze, her pussy squirting a spray of her juices onto the bed. Not breaking the spell that moved the cock up and down her throat, Twilight dragged a hoof down along her thighs and placed it on her drenched pussy. She began to rapidly stroke over her outer lips, moving to rub her swollen clit every time it showed up from under her labia.

But no matter how good she felt with her brother’s cock buried deep inside her, eventually biology took a toll and Twilight began to feel dizzy, then suffocate badly as her body had spent the last morsels of oxygen stored in her lungs. She enjoyed the last moments of her brother’s girth as much as she could before jerking the cock up completely in one pull, the flared tip brushing her from inside all the way from the depths of her throat to her lips until it popped from her mouth with a loud wet noise. As soon as there was nothing to cram her narrow orifice, a sharp cough overtook Twilight and she was forced to roll over onto her belly. Choking and gasping for air, Twilight finally made that needy breath that her body had so long demanded and allowed the oxygen to fill her burning lungs, a trail of drool leaking from her mouth unceremoniously. She panted heavily for a while, then levitated a towel from a nearby wardrobe and wiped the excess saliva off her face, as well as a couple of tears that had managed to escape her eyes before her throat had a chance to get used to the foreign object inside it.

Twilight threw the towel aside and turned to look at the artificial cock that was lying peacefully beside her. She couldn’t help but smile at the results of her work as she admired its slippery surface that was fully covered in her saliva, from the tip down to the base where a small puddle of her oral fluids accumulated on the two massive orbs. It seemed incredible now that there had been a time when she could barely take a quarter of her brother’s cock without throwing her dinner up before gagging to near unconsciousness.

“Did you like it, BBBFF?” Twilight was sure he did. If there was one truth that she’d learned from scores of books on how to please your stallion, it was that it’s easier to find a vegan manticore than a stallion who wouldn’t be head over heels in love with a mare who can perform a perfect deepthroat. And Twilight wasn’t known to be a mare who would ever stop until she’d brought all things to perfection.

“Now it’s your turn to please me.” Twilight giggled flirtatiously. She hugged the cushion before her and raised her ass high in the air, her tail flicking from side to side in excitement, revealing her winking pussy with the beads of sparkling moisture trickling down her thighs.

“Please don’t make me wait, Shiny.” She waved her rear back and forth, whining slightly. “I won’t be able to fall asleep tonight without your thick cock having pounded me.”

Twilight buried her face in the cushion as her mind conjured up the images of Shining Armor tenderly biting her nape, then going up to nip at her ear, his warm breath wrapping around her neck and cheek. He slid closer to her and Twilight felt the weight of his masculine forelegs press on her back, pushing her deeper into the bed. Her horn sparked and she let out a low moan as his cock brushed against her swollen outer lips. Shining flicked up her clit and began to travel up and down along her tight slit, teasing Twilight to her great frustration. She bit down on her upper lip as the heat inside her became every bit unbearable, all her thoughts focused on having her brother spreading her wide and pushing deep inside her.

As if sensing that his little sister was on the verge of collapse without his cock, Shining thrust forward, shoving the whole length of his stallionhood to the hilt inside her. Twilight instantly reacted at the contact and enfolded Shining’s cock in the sopping warmth, changing the shape of her pussy to perfectly match the curve of the cock, hugging it so tightly as if it had always belonged inside her.

“Yes!” Twilight cried into the cushion, her body trembling at an immediate wave of pleasure that surged through her. “I love you so much, Shiny. Please don’t stop thrusting.”

Encouraged by Twilight’s words, Shining slid his cock out a few inches before shoving himself in again, his balls slapping against Twilight’s ass as he bottomed inside her. After another powerful thrust that almost sent Twilight tumbling forward, he fell to a steady rhythm, moving inside his sister with rapid speed and turning Twilight into a trembling mess.

Twilight had to make every effort to keep her rear up, her pussy spasming around the cock, trying to hold her brother in as long as possible, wrapping it perfectly with no resistance at all.

“Yes, it feels so good,” Twilight managed between moans. She hesitated for a mere moment before deciding to recite some obscene phrases she’d learned from one particular smutty book before. “My pussy is being ravaged by my brother’s thick cock. Ahhhh. You’re so big, Shiny. Please fuck my tight pussy harder. I can’t live without your cock inside me.” Though there was nopony in the bedroom but Twilight, the words had left a big blush on Twilight’s cheeks even so.

Everything that she knew about sex was from either anatomy textbooks or shabby romance novels, as Rarity would put it. And almost in every such a novel, a stallion would like his mare to behave herself like a slut and worship his masculinity while in bed. Twilight hardly imagined her chivalrous brother would like such promiscuous behavior, but it wasn’t like she ever had a chance to spy on his and Cadance’s sexy night times to prove otherwise. So the only choice that seemed to make any sense was to cling to books – the only source of wisdom that never failed her – and hope that she hit the mark or at least landed it nearby. Not that she knew any better herself.

“Oh, Shiny, your cock is tearing me apart,” Twilight continued to moan as another strong thrust sent her face first into her pillow. “My pussy is spasming around your cock so tightly. Please use my pussy as a living fleshlight. Don’t ever stop thrusting.”

Shining didn’t seem to have a mind to stop and if anything simply complied, thrusting himself into Twilight with the relentless force of a beast breeding his bitch. Twilight winced at a jolt of pain running up her spine after an especially powerful thrust that almost penetrated her cervix but other than that gave away no sign of discomfort and only encouraged her brother to move even faster. She was so close to orgasm as to risk to slow down even a little. Besides, she was her brother’s bitch that he could do anything with as he wished.

A high shriek of pleasure broke free from Twilight’s throat as her and her brother’s union reached its apex. For a moment anxiety overwhelmed Twilight that her moans were loud enough to penetrate the protective spell around the room, but the fear of getting caught disappeared as quickly as it arrived and was replaced with a feeling of pure bliss circling through her body.

Twilight tightened her pussy around the cock with a vice-like grip, not wishing the feeling of complete fullness to ever leave her. Her hind legs buckled under her trembling body, sending her ass to drop onto the bed. As Twilight fell, more and more of her juices kept squirting from the tiny gaps between the cock and her pussy, turning the surface of white linen sheets under her rear into scores of viscous transparent pools emanating strong mare scent.

Her pussy dripping, Twilight lay motionless in her bed for a long while, riding post orgasmic waves with the cock still jammed deep inside her, the ballsack bumping against Twilight’s thighs every time her hind leg twitched at an unexpected jolt of pleasure. Even after the last traces of Twilight’s orgasm dwindled to nothing, she wasn’t in a hurry to gather herself from a sprawled mess of delighted unconcern. She was so happy being with Shiny, connected to him, feeling the bond that only two ponies loving each other could have. It felt so wrong to break that bond. And yet she couldn’t fall asleep with her brother’s cock buried in her pussy. The protective spell encircling the walls of her room was too delicate to maintain during sleep and if anypony, or for that matter any dragon or worse still some intrusive draconequus, found out about her feelings to her brother... Well, Twilight didn’t want to think about it. That’s why she took every precaution to protect her little secret, the secret that she would take with her to her grave.

Stretching her limbs, Twilight finally gathered enough strength to flip herself on her back. She shot a glance between her legs to admire how well she fitted her brother’s cock and what an ideal pair they were, then extended a hoof to grab the base of the cock. She began to withdraw it out slowly inch by inch, wincing as the cock’s length rubbed inside her oversensitive pussy and scraped at her still winking clit. With a sigh, Twilight pulled out the last inches of the cock from her pussy, then brought the tip up to her muzzle. An abundance of her juices dribbled off down onto her chest as she sniffed the sour fragrance in.

“Thank you, Shiny. You’re the best brother a pony can have.” Twilight assumed an impish smile. “I don’t know what I would have done without you.” She trailed her eyes over the whole length of the cock attentively as if she were afraid that she would never see her brother again, her juices sparkling, catching the violet light of the aura that surrounded the room. “Just give me a second, I need to clean you up before we turn in. We don’t want Cadance to know that you have more fun with your little sister than you do with your wife.” Twilight giggled at her own quip.

Opening her mouth wide, Twilight stuck her tongue out and traced its wide surface over the tip, then slowly began to move down the length, lapping up every drop of her pungent juices in her mouth and sending it straight into her stomach, her throat contracting visibly as she gulped everything down.

She glided her tongue over the cock until it looked as good as new and her jaw began to ache. She took a tissue paper out of the nightstand and wiped the dildo clean off her saliva. She gave her brother’s cock a farewell kiss on the flare and put it carefully into the box of the nightstand.

Twilight made herself comfortable on the bed and closed her eyes, preparing to fall asleep. “Good night, BBBFF,” she whispered, her magic securing the lock of the nightstand. “I’m looking forward to our meeting at the gala.”
