Why would you ask such a question?! [Nude Posing]

As the frosty breath of winter enveloped Ponyville, the excitement of Hearth's Warming approached with a sense of wonder and magic. This year, the festivities were especially exciting, with Twilight Sparkle and her friends planning delightful surprises for one another. However, as the preparations unfolded, an unexpected twist cracked through the icy white veil. Something that sent Rarity into a whirlwind of curiosity and concern. Her handsome little helper was no longer by her side.

Every year through the entire snow covered panic before the big day Spike was by practically glued to Rarity's fine hips. The little dragon was most useful in carry all of her supplies throughout town. Rarity had no need to carry heavy things like lumber and nails in her beautiful and delicate fingers. Not when there was a scaly little dragon just dying for a reason to flex his iron muscles. The sight of which always left her with an ever so soft blush on her cheeks.

So when Spike failed to show up at Carousel Boutique at the start of the week, she was slightly concerned. It was out of character for him. Especially around the holidays. The unicorn's worry was not eased by Sweetie Belle's lack of an answer for his whereabouts, same from her friends. Spike had simply been too busy to show up that day... or the next day, or the day after that.

Sure, since becoming an adult dragon, his sense of schedule had changed. However, he always made time for her around the holiday season. It had become such a regular thing to the point that she didn't even nee to bribe him anymore with kisses on the cheek. A small frown spread across her face as she looked out the front window of her shop, hoping to see him trudging through the snow.

The whole first two days of the week passed and he still didn't show up. That was when she knew something was very off. Thoughts of his arrival fluttered in her mind after waiting for so long. Images of him rushing and sweeping her up in strong muscles. He carrying her all the way to the shop in his brawny arms as an apology for being so late. Her blushing bright as his ripple abs pressed against her back and shoulders, the warmth of his hips against her...

A knock at the door luckily stopped the images from turning into a more intense visage than she wanted to admit. Strange, the short dragon has his own keys by this point. So why was he knocking? With a small frown, Rarity approached the door, ready to inform an unsuspecting customer that she was closed for the holidays.

She opened the door, her voice firm yet polite, “Sorry, but we are closed for the holidays.”

“I know…” came a familiar voice that cut through the crisp winter air like a warm blanket. Twilight Sparkle stood before her, her purple coat dusted with frost, eyes bright with a mix of urgency and apprehension.

“Twilight?” Rarity gasped, taken aback by the alicorn’s unexpected visit. “What are you doing here? Aren’t you busy with your holiday preparations?”

“Yes, but…” Twilight stepped into the warmth of the shop, crossing over to Rarity’s measurement stand as if seeking refuge in familiar surroundings. “It’s something important.”

Rarity’s heart raced at the weight of those words. “Something important?” she echoed, curiosity piqued.

“Yes.” Twilight’s cheeks flushed a deep shade of crimson, her gaze flickering as thoughts whirled in her mind. “I’ve got some… questions for you.”

“Questions?” Rarity asked, tilting her head in intrigue. The very notion of Twilight seeking her counsel was enough to ignite a spark of excitement.

“I’ve been talking to a few of the other girls about this… rather bold idea,” Twilight admitted, her voice lowering as if she were about to reveal a closely guarded secret. “I couldn’t come to you right away because I feared you would say no.”

“Well, you won’t know if you don’t ask, darling,” Rarity replied, a reassuring smile gracing her lips. The air was thick with anticipation; she could sense the weight of Twilight’s thoughts lingering in the air.

“Yes, I know,” Twilight's blush deepening. “But it’s… embarrassing.”

Rarity chuckled lightly, her amusement bubbling to the surface. “You shouldn’t feel embarrassed when bringing anything to me. I’m always here to listen and offer my help.” She reached out and gripped her hand tightly. "I'm the Element of Generosity."

"Yes, you'll certainly will be if you agree to this stunt..." Twilight murmured, her eyes darting away shyly. Taking several deep breathes, she turned back, determination gleaming in her gaze. “Oh, I’m not the one that will be embarrassed.”

The word choice sounded odd, but felt even stranger given the large moment of silence fell between them afterword. Twilight took a seat and gestured Rarity onto the podium, closing all the windows and making sure Sweetie Belle was still upstairs. Drawing the curtains around them, only add to the weight of her cold actions. Everything was sending Rarity’s mind racing with possibilities. What could possibly have Twilight so flustered?

"You can trust me, Twilight," she whispered, taking her place on the podium.

Opening her eyes, she fixated on Rarity, her gaze piercing and contemplative. It was a moment that felt both familiar and foreign. A sense within her tore through her chest and down into the pit of her soul. "We used to date... right?" Twilight's voice broke the silence hanging in the air.

Rarity raised an eyebrow, taken aback by the query. "Yes...?" Her voice trailed off, uncertainty lacing her words. It had been years since their brief but very, very intense relationship happened. It was a searing bright flame that burned so hot that it was almost too much for both of them. Ultimately flickered out when it began to create a rift in their group dynamics. Spike was left in utter distrait upon walking in on their powerful passions one night. Twilight’s younger brother couldn't take the pressure of his crush's exposed flesh over his sister's incestuous flesh. The stakes had been too high, and they both cared too much for him to shatter his heart.

"Why do you ask?" Rarity's curiosity piqued as she crossed her arms, a gesture of both defense and intrigue. Twilight appeared to be in a state of inner turmoil, her expression shifting between hesitation and determination. The unicorn took her own deep and relaxing breath, hoping to aid her former lover and dear friend. "There was never anything romantic... right?"

"No, no, nothing romantic at all!" Twilight blurted, a nervous laugh slipping from her lips. "Not a single thing... at all."

"Then why are you acting so strange?" Rarity couldn't hide her confusion and frustration. Her mind ran through the possible reasons, but none made any sense. They were far too random and disconnected, especially given Spike's absence today.

"It's... something personal," Twilight explained, her cheeks burning red once more. "I... want to ask something, and I was hoping it wouldn't seem too forward..." Twilight inhaled deeply, as if to steady herself for the question that would undoubtedly change the course of their conversation.

"I'm listening," Rarity replied, her interest now fully captured.

Taking a moment to gather her thoughts, Twilight felt the weight of her request pressing down on her. The gravity of it threatened to crush her nerves, yet she pressed on, "I... I... I..." The words danced on the tip of her tongue, but the courage to say them faltered. In a moment of exasperation, she released a breath, loud and clear, and shouted, "I need to see you naked."

Silence enveloped them. Rarity's eyes widened in shock, her brain struggling to process the abruptness of the request. A whirlwind of thoughts raced through her mind: Was Twilight jesting? Was this a bizarre form of apology? Or perhaps a cryptic invitation to reignite their past?

"I promise that while I can't explain, this is not a romantic... or lustful gesture," Twilight clarified, her voice softer now, tinged with urgency. "I'm asking out... scientific reasons."

As the words settled in the air, Rarity was torn between disbelief and suspicion. "Scientific reasons?" she parroted, unsure of how else to respond.

"Yes," Twilight nodded firmly, not giving anymore clear answer than that, but it was an obvious lie.

"You've already seen me naked before, Twilight," Rarity pointed out, her mind swirling with memories of their passionate encounters. Images flashed through her mind. Like spontaneous moments in the library where books would come crashing down with their bodies. Tentatively and powerfully stolen kisses against her pussy behind the thrones. A one very impulsive pounding in cart in just outside a building filled with elites blushing at their depraved sounds.

Each recollection left her dizzy, yet exhilarated. She had always embraced every physical aspect of their relationship, but Twilight's current demeanor signaled something deeper. Her gaze was not burning with lust, but with intense glare at the alicorn for such a crazy question.

"This is different," Twilight replied, her voice steady yet her face betraying the heat of her emotions. She was resolute, yet the implications of what lay ahead caused her heart to race.

Rarity's curiosity was piqued. "How so?" she asked, her mind racing with possibilities. The notion that this moment might revolve around measuring her body took her by surprise, yet it ignited a spark of intrigue.

"All those times... I was never measuring your body," Twilight confessed, the weight of her words hanging in the air. She tried her best not to recall those moments either or else. The alicorn never had the same level of control the unicorn had. Taking a few more breaths, or she would need to teleport away and back to her bedroom for another hour with the royal dildo. Damn thing has stopped Twilight three times day from arriving her and asking this question, she couldn't bail out now.

Rarity's intrigue deepened. "Is this for a fashion project? Perhaps a new line of clothing inspired by your research?" she inquired, trying to bridge the gap between her thoughts and Twilight's intentions. Luckily, such train of logic managed to push away the alicorn's more basic instincts and geld the fire trying to escape her legs.

"No," Twilight shook her head, her voice unwavering. The tension crackled through her sweat. This was the moment of truth. No turning back. No hiding behind a facade of science. This was for all the right and most selfless reasons. Even if it felt so wrong, dirty, and immoral.

With a hint of frustration creeping into her tone, Rarity pressed on, "Then what are you measuring? My arms, legs..." She pulled back her sleeves, deliberately teasing the moment as she lifted her dress. The atmosphere thickened, sending Twilight's heart into a tumultuous rhythm.

"Stop," Twilight's voice cracked, revealing the struggle within her. She was wrestling with the intensity of the moment, the weight of her desires warring with her need for clarity. "I just... I need you to... take off... everything." The words stumbled from her lips, each syllable laden with vulnerability and longing.

Rarity's eyes widened in astonishment. "Take off everything?" The shock was evident, yet beneath it lay a flicker of excitement that mirrored Twilight's own.

"Yes," Twilight breathed, her cheeks aflame as she battled with the undeniable hormones burning in her stomach.

The air thickened with tension as Rarity's confidence began to waver under the pressure of the situation. "All... my clothes?" Her voice quivered as she navigated the emotions roiling within her.

"Every last scrap." Twilight's eyes glinted with determination against her growing arousal. She was on an important mission that she couldn't fail. This was going to be the greatest Hearth's Warming present she could ever give.

The unicorn's hand riased to her cleavage, feeling her heart pound so loud. "Twilight, this is awfully sudden," she replied, a sense of caution entering her tone. Her gaze darted away, uncertain and shyness she never felt before.

"Please." Twilight's voice cracked again, revealing a hint of desperation. "I promise this is not meant to be... lustful... in any way. There's something I've been studying and your help is vital."

"Really?" Rarity's tone softened, her heart swelling at the praise. "my naked body is needed..." The words left her mouth so fast.

"Yes." Twilight nodded, her expression earnest. "Your measurements are necessary. For... a very unique... scientific reason."

"I don't know, Twilight," Rarity hesitated, her mind swirling with doubts. Caution wrapped around the heart of her busty and tight corset, but Twilight's earnest plea melted some of that apprehension. "Trust me, Rarity. This is very important."

With a resigned sigh, Rarity squared her shoulders and resolved to trust her friend and former lover's vision. After a moment of contemplation, she nodded. "Very well," Her voice steady despite the whirlwind of emotions within her. "If you insist."

As Rarity began to lift the fabric, her mind was a mixture of excitement and trepidation. She had pose for many occasions in her best attire, but never naked and never so for a current or former lover. With each piece removed, her skin was bathed in the chill of winter slowly seeming into the room. It sent a shiver up her spine and tingling sensation over her most sensitive spots. Her nipples tightened and goosebumps formed under her white fur.

Twilight couldn't look away. Her gaze remained fixed with sharpness and focus. She memorized every inch of exposed flesh. Her eyes traveled up the curve of her legs, lingering on her soft, pale thighs. She traced the outline of her hips, taking in the sight of her toned, slender abdomen.

As the fabric dropped to the floor, revealing Rarity's elegant and nude form, Twilight felt her heart race. The curves of her busty and luscious silhouette danced before her eyes like a work of art. Every contour telling a story of beauty and grace, giving her glances back to their most lustful and intense moments. The alicorn took a deep breath, reminding herself to remain professional as she jotted down notes.

"Now, please, stand straight, and spread your legs slightly," Twilight instructed, her voice firm, yet wavering with desire. Rarity obliged, taking a deep breath and allowing the cold air to fill her lungs.

Twilight's gaze lingered on her supple breasts. Her nipples stiffened under the scrutiny, sending a surge of warmth through her chest. She couldn't ignore the throbbing sensation between her thighs. Nor could she deny the thrill of being completely exposed to her former lover.

"Spread them a little wider," Twilight's voice lowered and turned commanding. A flush crept across Rarity's cheeks as she complied, parting her legs further. The cool breeze caressed her, raising goosebumps across her even faster and driving out a soft gasp. The sound left the alicorn lightheaded and little dizzy. She closed her eyes and took a few breaths to steady herself.

"Now turn around, please," Twilight's voice wavered slightly as the heat between her own thighs intensified. Rarity's heart pounded faster, but she obeyed, twisting on her heels to face away from her. She could feel the alicorn's eyes roving over her body, drinking in every single moment of the sights.

The cool air tickled her exposed pussy, causing a tingle to spread through her stomach. Twilight's gaze followed the curve of her ass, noting how smooth and toned it was. She felt the urge to reach out and grab a cheek, but resisted, her hand trembling against the notepad. Details needed to be very, very accurate. But how could she stay professional in this very horny moment?

Rarity's ears flickered, picking up the sound of a pencil scribbling furiously against paper. "How long do I have to be like this?" she asked, trying her best to remain composed.

"A little longer," Twilight replied, her voice straining. "Just a few more details." Her gaze traveled up the length of her spine, noting the delicate ridges of her bones. Each curve and contour spoke volumes, filling the alicorn's heart with memories. Memories of the soft moans and gentle kisses, the tender caresses and the passionate embraces.

It was easy to get lost in the elegance of everything. From those enchanting hips, the gentle swell of her curves, and the way her ass and breast shook with each step and twist. The alicorn was transfixed, and it took every ounce of her willpower not to pounce. Her body was a perfect and erotic specimen, a vision of sensuality and deeply sexual energy.

Rarity's heart was beating rapidly as the moment stretched on. She was beginning to grow nervous. What was Twilight doing? Why did she want her measurements? What was all of this for? And where was Spike? Wait, what if Spike were to walk in while all of this was happening? A small blush began to spread across her cheeks, her mind filling with images of him walking in on them. His jaw dropping, eyes widening.. his iron muscles flexing and his hips parting to reveal...

"Okay, I’m done!" Twilight's voice rang through the room, abrupt and filled with a fervor that caught Rarity off guard.

The sheer urgency in Twilight’s tone made Rarity spin around, her heart racing. The alicorn was leaning back, visibly flustered with her hands fighting against her horn's glow against the clothing. "Really?!" Rarity exclaimed, a mixture of surprise and concern flooding her senses.

Her cheeks flushed and her body trembling with desire. "Yes! Very much done! We are good here! All is fine and great and... and... I am a horrible pony!" With that declaration, Twilight vanished back to the castle, leaving the unicorn standing there in a haze of literal naked confusion.

What just happened? Rarity's mind raced as she attempted to process the emotions that had just unfolded. Twilight’s declaration hung in the air like an unfinished spell, heavy with implication. The warmth flooding Rarity’s cheeks was the moment she realized her window was wide open. Shaking off her state of bewilderment, she quickly grabbed her dress over her naked exposure. Leaning over, she could have swore the thing had been closed the entire time.

Stranger yet was the odd and salty smell in the air... along with a distinct splash of an odd liquid on her outer wall.

Time To Settle The Craving [TwilightXFlash Bot]

Twilight Sparkle landed back in her room and threw the notes onto her desk, before rushing into her covers. The alicorn mare felt the combined forces of intense cold and the warmth of her embarrassment and shame wash over her. The images and sensations had been too intense for her to handle. Just why did she agree to this horrible idea?! She couldn't stop thinking about her former lover's body. It was beautiful, breathtaking, and incredibly enticing.

"It was all for... Spike... All for Spike." Twilight muttered to herself, trying to calm her pounding heart. "I just need a bit of fresh air and some food and everything will be alright." She repeated that mantra over and over, unable to get up at all. Her mind continued to replay the scene again and again, the images flooding her senses. The curve of her back, the softness of her breasts, and the way her ass swayed when she turned.

Twilight's arms had a mind of their own, reaching over her plump nipples under her shirt. She pinched them hard, the pleasure shooting through her, causing a gasp to escape her lips. "No... I can't have these thoughts again..." she pleaded with herself. "This is not the same as before."

Her horn lit up and drop book after book over her face. She could only hope these tomes would be solace enough. However, each page was filled with lewd choices in stark contrast to what she wanted. As if her spells wanted to help her in the worst ways possible. The alicorn tried her best to keep the images from invading her mind. She attempted to block out the memory of Rarity's supple flesh pounding against her.

As she rolled back and forth on her bed, the familiar surroundings of her room felt suffocating. The walls were adorned with various pictures and artifacts that had served as constant reminders of her accomplishments in life, but none of them compared to the lustful thirst with Rarity. Her eyes were drawn to the photos depicting her and Spike, his bright smile and cheerful demeanor always lifting her spirits. His crush for Rarity felt so genuine and real, so cruel for her to keep the mare all to herself. "This is why I'm doing this..." she whispered, tears forming in her eyes. "To help him."

She tried to push those feelings away. With each passing second, her restlessness grew. Soon enough it was an almost unbearable sensation that tugged at her pussy. It was a deep ache that needed to be scratched. Such a throbbing desire coursing through her veins, screaming for freedom.

“What can I do to distract myself?” she thought. A casual spell to organize her books? No, that felt too mundane. A trip to Sugarcube Corner for a cupcake? While sweet, it wouldn’t quench the deeper need stirring within her. Maybe watching a race between Rainbow Dash and Applejack, the adrenaline pumping through her as she cheered on her favorite. Staring deep into the sweat glistening off their... sexy bodies.

"Nope, not going to work!!" She screamed at herself, slamming her feet into her covers, feeling her hands slip past her skirt. The cool touch against her slit made her body tingle. "No... I need to begin... Designing it..." Her voice was a whisper, her mind swirling with fantasies of the gorgeous white mare.

The truth was she needed this release. A way to express the overwhelming lust swirling inside her. Her body ached, and the only thing that would soothe it was a long, hard, and intimate session with the royal dildo. "Damn, my horny cunt!! Flash get in here!!"

With that word, her closet opened up, and smoke bellowed out. When the magic settled, a pair of blue eyes shined out of the blackness. Stepped out was a very rough robot stallion. It was a poorly designed replica of that human from beyond the mirror mixed with some details of that one guard from the Crystal Empire that he shared a striking similarity to. Twilight lifted her head and admired the figure's design and state. It constantly puffed smoke and cranked with loud gears, but its cock was absolutely perfect. While it was enough for her, she feared the version for Spike would need to be far more accurate.

"How may I serve you, Princess?" the robotic figure asked, his voice sounding slightly distorted.

"I need your cock!!" She demanded, locking her room up tight with a powerful soundproof spell. After this, she leaned back and pulled down her panties.

The machine tilted its head and gave a loud popping sound. Carefully it walked forward to the edge and the bed. Twilight lifted her legs and wrapped a spell around his metal hips. They opened up to reveal the royal dildo, ready and willing for her. With a grunt, the fake Flash pushed his rod deep into the mare's waiting pussy.

She moaned loudly, her body arching at the sudden intrusion. It was a familiar feeling, but still a shock nonetheless. The machine thrust into her, its rhythm slow and methodical. Each stroke sent waves of pleasure through her. She could feel her walls stretching, accommodating the thickness of his length.

The pleasure built within her, the tension coiling tighter and tighter. "Yes, yes, more!!" She moaned, her eyes rolling back as her body shuddered. The alicorn pinched and twisted her breasts out of her shirt, making sure she had plenty of room to enjoy her body.

The Flash Bot responded, increasing his speed. His movements were precise and calculated, the dildo hitting her g-spot just right. The machine knew exactly how to satisfy her, his thrusts hitting her deep. Yes, this experience helped a whole lot. Now she could make sure Spike's present could satisfy him in the same way her own machine did for her.

"I am... getting... close!!" She cried out, her walls clenching around the robot's length.

The machine increased its speed even further, its hips moving like a piston. The pressure inside her was becoming unbearable, her body writhing under his mechanical ministrations. She shivered and shutter, rolling onto her belly, pressing her hips back and forth onto it.

Her legs parted wide, giving the machine full access to her tight pussy. The machine adjusted itself, penetrating her deeper and deeper, its length filling her completely. She felt the wave of her orgasm approaching, her muscles tightening. Her body shuddered, the sensation overwhelming her. Her mind went blank, the world disappearing around her as she rode the ecstasy. The image of this facade of another former lover was replaced by the other one in her mind. The thought of her and her naked body and her moans were the final trigger, pushing her over the edge.

"No... No... Rarity!!" Her body jerked and trembled, her orgasm hitting her with force. Her juices flowed, coating the Flash bot's dildo. Her muscles contracted and her toes curled, the pleasure spreading through her. Her mind was a haze of lust and euphoria, and her body was overwhelmed by the sensations. The machine kept pumping into her, making her spasm even harder. Sensing her climax, it opened a special compartment above the metal penis. This revealed a small hose that blasted fake semen all over her back. The warm sensation sent her into another wave of pleasure. She collapsed onto her bed, spent and satisfied.

After a few moments, the robot retracted its dildo and walked back into the closet. "That was so good," she gasped out loud. "But my little brother deserves so much better than this..." she smirked to herself. "Yes... his Rarity Bot needs to feel so real..."

Author's Note

Yes, this was planned to be longer, but brain frying right now. Just wanted to clean this up and post it. So sorry if this one feel a little rough compared to chapter one.

Construction [Nothing Explicit... unless you has a Lego Kink]

After stress-relieving for a full day, Twilight was able to rip herself from her room long enough to begin her work. She had to be sure that her designs for a Rarity Bot were exactly to the real Rarity, but also finish before Hearth's Warming Day. She was lucky that her brother was a patient dragon. Hiding in his room all day while she worked in her library.

Arriving there, she laid several machine pieces out in a skeleton-like frame. The task at hand was not simply about crafting a machine that resembled her dear friend, Rarity; it was about creating a bot that could embody Rarity’s elegance, creativity, and spirit. This was no small feat. Unlike her previous creation, the Flash Bot, which had been more functional than fashionable, the Rarity Bot needed to be an absolute masterpiece.

This would take a delicate approach, not only for the sake of accuracy but also for her own sanity. She couldn't have this project be consumed by her former lustful feelings. Twilight had to maintain a level of sexual detachment while she worked. It wouldn't be easy, but it would be worth it to see his smile once the work was done.

She looked at her sketchbook. "Okay, let's get started." She took a deep breath and began piecing together the first leg.

Her focus was complete. Nothing would distract her from this project. The sound of the metal clinking against metal echoed throughout the room, filling her with a sense of satisfaction. She hummed to herself, lost in her own little world as she worked.

Twilight was grateful that her brother was respectfully waiting in his room. He seemed to have an instinct that something was up as she often heard him grunting out a good waxing every time she stepped by his room. That's why he was so quiet and well behaved, but also so patient She hated deceiving Rarity so cruelly by having him watching her while she sketched out the details yesterday.

As the minutes ticked by, the machine slowly began to take a very bony shape. Each part was carefully crafted, and the entire thing was meticulously put together. Her brow was furrowed in concentration, her attention to detail never faltering. It was painstaking but necessary.

Once the frame was perfect, she began the hardest part. The soft and firmness of the outer shell. The skeleton was to be made from a thin but very strong metal, allowing for mobility and durability. The first layer of the exterior was then covered in a layer of plastic to ensure no sharp pinches inside. This was very different from her Flash Bot design which only had a thin plastic sheet to prevent metal from scratching against her inside.

She knew Spike has a sharp and powerful cock. This was from her other notes taken throughout the week before arriving at Rarity's place. The Rarity Bot needed to be built to handle his rough and passionate sessions. It was an expensive and difficult process, but Twilight was determined to give her brother the best.

The next layer was a special type of latex that mimicked Rarity's insides, with particular work around the mouth, pussy, and anus just in case Spike got very creative with his fetishes. The material was a unique blend that could stretch and conform to his bumpy and curved shaft. Twilight was careful to match the measurements to the last millimeter., but also made sure it could stretch if Spike's endurance proved far stronger than her own experiences with Rarity.

It took her three full days and multiple trips to the market, but the end result was worth the effort. A long road, but not even close to her hardest part. Harvest and mix a unique combo of rare and unstable material into a far more stable and strong latex to make it look, feel, and even taste like a real pony.

As she mixed the ingredients together, the alicorn's mind wandered. Memories of their intimate moments together, the sensations of her skin, and the scent of her perfume filled her senses. She was reminded of the way Rarity would moan, and how her body would tremble under her touch. Twilight closed her eyes, her heart aching with longing but pushed it away for the sake of Spike.

She snapped out of her trance with a hard slap to the face. Twilight knew that a successful Rarity Bot would require more than just a very rough physical resemblance. She had taken careful measurements of Rarity's face, neck, and limbs. This was the foundation for her, but now she had to get the details right. The fine lines and creases made Rarity's face beautiful.

With a sigh, she got to work. She spent hours far harsher crafting each feature, using every note and reference. Every piece was in its proper place, fitting together perfectly. The details were incredible, the expressions almost lifelike. Twilight was impressed with herself, she could almost swear that the real Rarity was looking back at her... outside of those mechanical eyes and faint glow.

Her hands glided over the rest unique latex, her fingers molding it to fit the contours of the body frame. It was a slow process, but a necessary one, particularly when it came to her breasts, ass, and thighs. All of which she always considered Rarity's best features. She had to get the softness and firmness just right or else it would be an absolute insult to Rarity's erotic form.

She could feel the heat rising inside her as she worked, her mind lingering on those moments together. The way her body trembled under the touch as the body became more real. The warmth of her breath guided over the glossy white fur. It was a powerful temptation that she needed to fight. The Rarity Bot was not about her desires or urges, it was about fulfilling her brother's basic needs.

She had to remain focused with the final task being just as critical. She had to create an exact replica, not only of Rarity's appearance but also her voice. Twilight had been recording Rarity moaning behind her back while she slept with the occianal stallion. The best samples came from nights with Big Mac, Braeburn, and Caramel. Making sure to leave out those horrible nights with Thunderlane since the dumbass liked the grunt too much, interrupting Rarity's lovely voice.

Twilight took a deep breath, closing her eyes and focusing on the task at hand. She listened intently, carefully matching the sounds. The moans and gasps were recorded and stored in a crystal with the machine's casing, ready to be used. She was certain that Spike would appreciate the extra attention to detail.

Author's Note

Yeah, nothing much happening here outside of how much work Twilight had to put into this thing. I know people were expecting a sentient sex toy, but no, that was never the plan. So sorry.

That doesn't mean Rarity can't get jealous of it.:raritywink:
