Princess Cadance loves the new dress Rarity made for her. For her reward, the Princess offers to breed the fashionista mare.

FEATURED September 19 - 20 2023

Rarity has been commissioned by Princess Cadance to design a rather special dress for the alicorn; one that hides a certain, "special" feature of hers between her legs. Once finished, and remarkably satisfied with the results, the Princess offers a suitable and special reward to the hardworking unicorn; the chance to be bred by her. Reluctant at first, Rarity soon warms up to the idea, and Cadance gets to turn this beautiful fashionista into her special broodmare.

This is a Commission for Tailsic.

A Special Reward

Late at night, in the heart of the Crystal Empire, a lone window’s light cast a faint illumination against the splendor of the crystalline capital. Within this workshop, a unicorn mare, Rarity was busy putting on the final touches of a dress fitting for the ruler of the Empire, the alicorn princess, Cadance. The much taller mare was dressed in a beautiful gown. A darker pink dress that tightly hugged her curvaceous body, cut low in the front to put her gorgeous, lighter pink breasts in almost full display, and raised in the sides to show off her round flank a little more. She would be the envy of any mare who would gaze upon her in such an outfit.

Rarity was hard at work too, magically putting in the final stitchings, as well as carefully weaving magic into the fabric. So hard was she working, that her button up white shirt was getting wrinkly from the faint sweat, and the short black skirt was riding up to just barely show off her exotic lingerie. But none of that mattered to her, she was in the zone as it were, and was nearly finished. Cadance said nothing, only smiling at the mare hard at work. She made the right choice setting up a branch of Rarity’s boutique here in Crystal Empire, and the unicorn certainly knew her trade.

“And there we go, perfect!” Rarity commented, wiping the sweat from her brow as she took a step back. Immediately, her horn ignited, pulling over dozens of mirrors to allow Cadance to gaze at herself from every possible angle. “Such a magnificent gown, wouldn’t you say? Look how it shows off your every curve, and how it brings you out as the center of attention.”

“Such a wonderful dress, I greatly appreciate it Rarity.” Cadance replied, smiling as she looked at herself over and over again, especially along her waist, hips, and flank. “I must say, I am beyond impressed as to how you managed to conceal my…secret…”

“Well, yes…it wasn’t…that hard…” Rarity nervously stuttered, blushing a little as she composed herself. “Weaving concealment spells into the dress should do good to hide it, but once you take off the dress, you should be able to-”

Looking over to the alicorn, Rarity’s words were cut off as she saw Cadance moving her dress a little, lifting it as her massive cock and huge balls spilled out. To call them hung and heavy would be a major understatement. The princess’ cock was big, easily as tall as a large colt or filly, and nearly as thick as, even limp, nearly reaching her ankles. While her balls were equally as impressive, bigger than a ponies head, they were only a little bit bigger than the alicorn’s already massive pair of tits. Cadance only looked at her cock and balls, nodding with a smile on her face.

“Yes, yes, this dress should do.” Cadance commented, covering herself again in the dress, to which it magically repressed the cock and balls, hiding it perfectly away. She did this a few more times to see herself have one, then hide it, then have one, and then hide it again. “Perfect, such master craftsmanship. This dress is perfect for the coming Grand Galloping Gala.”

“I’m so glad you approve of it.” Rarity smiled, trying to compose herself a little more. She had never seen anything so big and masculine before, not even when she and Twilight spied on the mating habits of dragons when Spike got old enough. “Just be sure not to let the dress come off and your secret will be safe.”

“Perfect, I couldn’t have asked for a better dress.” Cadance nodded, smiling as she considered something. “Now, what sort of reward would be suitable for your services?” Pondering a little, she snapped her fingers as the idea struck her. “Oh, yes! That’s perfect too! I know how I shall reward you. I’ll breed you.”

“Now, now Princess, no rewards are necessary. I was only doing my-” Rarity commented, only to fully hear what Cadance said. “I’m sorry, but maybe I misheard you. What did you say?”

“You heard correctly.” Cadance replied, smiling at the mare as she started to stroke herself as her cock grew in size. “I cannot think of a more suitable reward for you than to impregnate you with my foals.”

“I-I-I-I…I’m sure it would be great, but I just don’t know if I can.” Rarity replied, trying to talk her way out of this, but she couldn’t look away from Cadance’s cock. The way it was throbbing, part of her wondered what it would like to feel such a girthy thing inside her. Shaking her head, she continued. “B-b-but I would like to politely decline this gift.”

“Oh, don’t be like that.” Cadance replied, maintaining her smile, having heard this routine so many times with many other mares. “Aren’t you at least…curious?” Rubbing her cock, she swayed it from side to side. “Even if you don’t want to be impregnated, wouldn’t you like to at least take this as a thank you for your hard work and dedication?”

Rarity continued to stare on, swallowing nervously as she could almost feel the heat of this cock as it was getting closer and closer to her. Her body was starting to feel faint tingling all along her body. Her nipples were getting hard from the powerful musky smell, and the warmth that was radiating off it was starting to make her pussy wet. Cadance could see this, the same nervous trembling that she had seen so many times before. Rarity was giving in, and she was soon going to wet this royal cock.

“So…what do you say?” Cadance asked again, seeing as Rarity’s resistance was weakening little by little. “I can even cast a little magic to make you feel even better too.”

“R-really…” Rarity asked nervously, somewhat getting a little more comfortable as the cock was close enough to nearly kiss. The potent musk was making her head dizzy. “W-w-w-what is it?”

“A spell that would allow you to be a little more flexible. So that you can handle this size without issue.” Cadance answered, speaking plainly and directly to the mare. “I wouldn’t want you to get hurt from this thing otherwise.”

“I…I…I suppose…if there’s no risks…” Rarity commented, starting to relent and submit to the idea. Her body was trembling, and the musky smell of Cadance’s cock was certainly not helping her think clearly. “J-j-j-just…please be gentle. It’s been a very long time since I’ve been touched.”

“Don’t worry, I will.” Cadance smiled, igniting her horn with magic. The arcane essence of her spell took shape, wrapping around Rarity’s body like a pinkish colored mist. The unicorn’s body shivered as she felt the magic take hold of her, but otherwise, she felt nothing else. “There we go, much better.”

“Really?” Rarity asked, looking herself over. “But, I’m sorry, but I don’t feel any different.”

“Oh, right, so you’ll feel it in a moment.” Cadance commented, rubbing the back of her head and a playful giggle. “Let me show you.” Leaning in, she kissed against the mare’s lips.

Rarity came with a wet, sloppy orgasm. Her body was shivering, almost thrashing as she felt the way this cock was hammering into her. It was the best feeling she had ever felt. It wasn’t like Rarity had never tasted such passions before, but it was for business, or some small flings and trysts here and there. But with Cadance, this was different, this was a raw, primal instinctive breeding that was going to happen, and she could feel her womb quiver in anticipation.

“Oh wow! Cumming already?” Cadance commented, slowly turning the mare around. “Don’t worry…I won’t be gentle…”

Before Rarity realized it, Cadance had moved her to bend over her work table, her ass pointed towards the princess, and her sobbing pussy was soaked and quivering with anticipation. The unicorn could only moan, almost feeling the heat radiating off the alicorn’s massive cock as she was pressing it against these moist lower lips. Cadance hummed, playfully teasing the mare as she was slowly slipping her way into her, but not too fast.

“...please…please…” Rarity cooed, moaning quietly as she was shivering with anticipation and yet impatience. She wanted it, she needed to feel Cadance’s cock deep inside her, and yet the alicorn was teasing her. With the magic coursing through her, pride and reason no longer existed to the mare. “Please…Princess…fuck me…breed me…make me you slu-aahhh!”

At once, Cadance thrusted forward, nearly bottoming out in the mare’s pussy. Rarity screamed out a breathless cry of euphoric pleasure, rolling her eyes back a little as she could feel her body being stretched and filled. Even with the magic allowing her to handle such a girth, it still felt so massive. It was like every part of her insides were submitting, making way for Cadance’s cock to fuck deeper and deeper.

“Fuck…so big…” Rarity moaned, shivering as she was hunched over her table. Her round tits pressed hard against the smooth wood, rubbing against her shirt as she was being fucked faster and faster. “So good…this cock…it’s…it’s fucking me so hard…”

“Oh? You think that’s hard?” Cadance asked, giggling a little as she looked over to Rarity. “I was just getting warmed up.” Her lips curled into an almost sinister smirk. “If you wanted hard, I’ll give you hard.”

Before Rarity could even say another word, a strike of pain rippled through her as Cadance brutally smacked her fat ass. She yelped out, gasping in the pain, but then moaning as she felt the growing pleasure of the strike against her flank. Cadance only laughed, smacking her ass again as she was fucking in and out of her pussy. The unicorn was screaming out, cumming her sloppy wet passions all over this mighty alicorn cock. The princess didn’t let up for a moment, not showing the fashionesta any mercy as she was seemingly set to fuck her to the point of ruin.

“Fuck, fuck, fuck, fuck, fuck me, fuck me more!” Rarity panted and screamed, gritting her teeth every so often, shivering and twitching as she came again, feeling her pussy tighten and squeeze around this length. “Fuck! Breed me! Make me your bitch! Knock me up! I want it! Making me your drooling whore!”

“Oh damn, I figured you were pent up, but this…” Cadance laughed, cooing and moaning as she was feeling the tight wetness of this mare’s pussy walls around her cock. “I’m happy to be the one to really let you be yourself, a whore.” Her words became harsher, as her lips curled to a more dominating sneer. “And a noisy whore like yourself will love…this!” Reaching around, she grabbed at Rarity’s arms, tugging them back.

Rarity screamed, cumming as she felt the blunt end of Cadance’s cock beat hard and fast against her cervix, sending a signal of pleasure; as well as a primal feeling of longing and breeding. The unicorn’s ovaries were quivering, releasing as many eggs as they could to ensure not a drop of cum boiling up in the alicorn’s balls would go to waste. Cadance arched herself back a little, making sure to lean Rarity upwards as well. Thrusting in and out of the mare, Cadance’s horn ignited, firing off an enchanted flame. Though it didn’t harm the unicorn, it burned away Rarity’s clothes, rendering her naked. Her round tits bounced free, lifting and dropping as her body was being fucked faster and faster.

“Fuck, you’re so tight!” Cadance groaned and moaned, feeling herself getting harder and harder as she fucked to the rhythm of Rarity’s moans. “Maybe it’s a good time to tell you…that spell I put on you. You know, the one that makes you flexible. Well, I wasn’t entirely truthful.” Her lips curled into a playful, yet controlling smirk. “It’s also…a powerful aphrodisiac spell!”

Rarity gasped some more, moaning more and more about it. Cadance was certain that the magic had begun to fully take its effect on the mare. Soon enough, the unicorn would have nothing in her mind but the desire to be bred. Maybe a few words would slip out of her fucked silly mind, but it would be primal, raw, and instinctive as she would only crave the urge and feeling to be stuffed with so much cum, she’d be a bloated, sloppy mess for months. The thought of seeing Rarity like this only further excited the alicorn, making her cock harder.

Reaching forward, Cadance released her hold on Rarity’s arms, and instead was violently groping at the unicorn’s tits. She screamed out, feeling as the Princess’ fingers were teasing, tugging, and playing with her nipples. The unicorn shivered, panting as she was feeling the skills of the alicorn’s hands groping and playing with her tits. It only made her pant and moan some more. She couldn’t think, what words and moans that left her mouth were little more than instincts.

“Come one, you can say it.” Cadance teased, looking at Rarity as she was thrusting upwards and forward, pressing the mare’s tits together. “You can do it, tell me who you are.” Rarity hesitated, only moaned some more, but the princess wasn’t going to have any of that. “Say it you whore! Who are you?”

“I’m your slut!” Rarity screamed, cumming another sloppy puddle of an orgasm all over the floor. “I’m Rarity, your breeding slut who wants her princess to fuck all your foals in my tight pussy.” She huffed and moaned, feeling as her eyes rolled back from the pleasure. “Please knock me up! Make me your pregnant, sloppy, whore bitch! I’m just your little breeding slut!”

“There we go, that’s what I wanted to hear.” Cadance hummed, releasing her hold on Rarity’s tits. This caused the mare to fall forward, laying again against her table. “Now…” The alicorn’s hands lay on the unicorn’s hips. Her lips were in a confident, dominating smirk. “Now I’m going to fuck you full!”

Faster and faster, Cadance hammered her cock in and out of Rarity’s pussy. The mare was moaning and screaming in constant, powerful orgasms. The alicorn huffed and moaned, feeling as she was about to cum. Rarity was about to be stuffed full of life giving, potently thick cum. Cadance shivered with delight, the feeling of impregnating another mare was a thrill that sent ripples of pleasure throughout her body. The mares were panting and moaning, their heart beats were pounding together, a synchronization of passion as they could feel they were getting close.

“Oh Rarity, it feels so good.” Cadance cooed, moaning softly as she could feel her cock swelling in Rarity’s pussy. “I’m about to cum. I’m about to fill you with my darling foals. Isn’t it wonderful?”

Rarity said nothing, only moaned and panted, the effects of the alicorn’s spell had utterly shattered her mind. All that mattered in her was this big, fat, beautiful cock stuffing her insides, and the cum that was about to flood every inch of her fertile womb. The way this massive cock was fucking faster and faster in and out of the mare’s pussy, the way that even flexible enough to bulge out, was still so tight, nearly crushing and rubbing along this royal girth.

Picking up her speeds, Cadance’s panting breath was moving faster and faster, her own large tits were bouncing madly, and her balls slapped hard against Rarity’s thighs as she was about to cum. She could feel the vast amount of cum churning and shifting in her hanging balls, the alicorn’s body was getting hotter, almost to the point of her sweat was steaming off her body. Rarity only moaned out some more, her body was aching, begging to be stuffed full of this cum. Any moment now, the feelings of passion, love, and a primal urge to breed will all come together, and this unicorn would feel complete with foal.

Just as she was ready to blow her load, Cadance moaned out in pleasure, bottoming out her massive cock as hard and deep as she could. Rarity gasped a breathless scream, feeling as this royal dick was fucked so hard and deep inside her. Fucking past her tight cervix, she could feel as Cadance’s cock pushed against the inside of Rarity’s womb. The unicorn’s ovaries quivered, stimulated from the pleasure as she fully submitted to be bred. The alicorn gasped out as she couldn’t hold herself back, and finally came.

Cadance’s orgasm was big enough to rival the girth of her cock. Rarity’s body was subjected to a torrent of cum. Her womb was flooded, stretched, and even then, it wasn’t enough. The alicorn pumping this virile amounts of hot spunk continued to bloat out the mare’s belly more and more. Rarity gasped, her eyes rolled back as her tongue was hanging out the side of her mouth. Even then, it wasn’t enough for Cadance; she was still going.

More and more cum was being released in her womb, and more and more of her belly was bulging out as more and more was being pumped. Rarity was gasping, panting for breath as she was cumming over and over again as she felt herself shivering from all the hot spunk in her. Cadance’s cock, as thick as it was, corked up Rarity’s pussy, making sure not a single drop was wasted as she was rubbing in and out still.

Eventually, Cadance slowly pulled herself out of Rarity’s pussy, letting out almost buckets worth of cum spill to the floor. Without the alicorn’s cock to hold her up, the unicorn’s legs wobbled and quickly gave out. Falling to the floor, Rarity splashed in the pool of hot cum and mare juices, twitching as she gurgled and wallowed in the afterglow. Even Cadance had to stumble back, feeling a little winded from cumming so much.

“My word, Rarity. That was certainly more than I expected.” Cadance commented, trying to catch her breath as she looked at the mess she caused. “I don’t normally cum that much, but you felt amazing.” Smiling at the mare, she could only imagine how many foals she had just fucked into her. “You’re going to be a fine breeding slut.” Rarity would only coo, too weak to say anything else as she instinctively rubbed her new impregnated belly.
