Mischievous Moondancer

“At least you didn’t tell me I’d look hotter without my glasses on.”

Moondancer stepped out of the fitting room, wearing a long dress that covered her body from her well-sized breasts down to past her feet. Glimmering in its dark purple color, not that much darker than her mentor’s mane, Moondancer watched as Rarity’s eyes lit up, her hands clapping as she grinned from ear to ear.

“Why, darling, you look simply divine!” Rarity gasped, the white unicorn being considerably shorter than Moondancer. But what she lacked in height compared to the other unicorn she more than made up for in her breasts and ass, something that Moondancer remembered each time she looked at Rarity.

For several years, having her reunited friends in Canterlot plus her studying was all well and good. Quite exciting at times even. But friends and studying wasn’t exactly going to make the futa unicorn woman’s dick cum, especially since said friends all seemed to be straight and not the least bit interested in getting dick from a futa. Being the best of both worlds was more fun on paper than in real life, Moondancer supposed. But then a couple of months ago, she had hung out with Twilight who accidentally slipped that Rarity was into both, having had a crush on Applejack for a while. And due to the crappy taste of the men in Ponyville, Rarity was single on top of that! That detail didn’t matter too much though, considering Moondancer didn’t mind if she had to be the Mistress in somepony’s relationship. But she knew taken mares were far more likely to reject another’s advances, so it was definitely easier to have Rarity single for her plans.

During her last stay at Ponyville, Moondancer had spoken to Rarity about how unkempt the yellow unicorn looked and how she deeply wanted to further distance herself from the shut-in lifestyle she once had. Taking up fashion lessons as her apprentice and making more friends in Ponyville would do just that. Rarity took the bait far easier than she expected, asking the yellow unicorn when she could start. Within the confines of her dress, wearing no underwear, Moondancer felt her dark yellow bitchbreaker twitching furiously. Even though Moondancer hadn’t removed her glasses, she had a pair of new dark red glasses that replaced her old and broken ones and complemented her mane more. Also instead of her unkempt bun and tail, Moondancer’s mane was down and in a different style entirely different from the Twilight copy style she once had. No bangs, and it was all reaching down to her shoulders. Shiny and clean from the shampoos and conditioners Rarity insisted she use, Moondancer felt she had progressed a long way from the angry unicorn who didn’t take care of herself. She not only looked good, but felt good. Though her own body wasn’t the main focus…

Rarity was wearing a short and tight bright blue dress that emphasized her heaving breasts and hourglass figure. Honestly, if Moondancer knew what hot friends Twilight had years ago, she would’ve forgiven the alicorn much faster. Glancing down at her dress with a planned frown, Moondancer felt her own chest with both her hands.

“I suppose I look decent enough,” Moondancer pouted. “But all the dresses you have won’t make my boobs bigger, and I doubt mares would find me eye-catching enough to go out with me…”

“Nonsense! Don’t you dare say that!” Rarity scowled as she predictably rushed forward towards the raised platform Moondancer was standing on to display herself. “You look very beautiful darling, I hope you know you don’t have to have a mane like Twilight’s in order to be your own unique flair of attractiveness.”

“And my boobs?” Moondancer threw the bait a second time, this time cupping her slightly smaller breasts with both her hands so that Rarity would have little choice but to notice them. Sure enough, Rarity’s face briefly scrunched up as she blushed through her snow white fur before she laughed and looked away.

“There’s nothing wrong at all with your chest size, darling,” Rarity chuckled. “Now please, if you could just-”

“Then you wouldn’t mind seeing them right? Straight mares such as yourself have done that for plenty of clients before without making it awkward, surely,” Moondancer gave a big wolfish smirk as she watched Rarity’s blush explode from the light shade to a full-blown tomato, this time staring Moondancer in the eyes.

“I…wuh…but…”

“Though you’re not straight, are you?” Moondancer added. “Your alicorn friend accidentally spilled that you were into both, and likely thought nothing of it. That’s not her fault, she doesn’t know that I’m packing or anything like that.”

“Packing w-” Rarity’s jaw dropped as without another word, Moondancer grabbed two fistfuls of her dress and lifted it up to reveal what she didn’t notice before. The spacious dress had effectively covered up enough of Moondancer’s bulge, as well as the musk. But seeing nearly a foot long of musky twitching futa dick caused Rarity’s eyes to widen, her heart to start pounding, and her mouth to water. Realistically, having Moondancer flash her so rudely should’ve been more than enough reason to kick out the other unicorn, even if she was very polite up until that moment. But what Moondancer didn’t know was that the fashionista, having hooked up with stallions and mares in the past, never hooked up with a futa lady before. She hadn’t even looked at the yellow unicorn woman’s breasts yet, and yet Rarity was already imagining experiencing both the familiarity of another woman paired with the masculine rutting of a dick inside of her.

Moondancer grinned with her teeth flashing openly at Rarity’s display, finding the other unicorn woman’s reaction better than she could’ve ever hoped for. Rarity couldn’t be in a more sexually vulnerable state, and Moondancer slowly brought her hand to the top of the other mare’s dress as she started to lower it. Rarity’s eyes landed on Moondancer very slowly undressing her while keeping one hand on her own dress to expose her futa dick, yet the fashionista did nothing except close her mouth and bite her own lip. Not sensing the mare refusing her advances, Moondancer’s horn lit up with an unexpected magic surge that took Rarity’s dress and yanked it down all the way. Rarity yelped at the surprise movement, immediately bringing her hands to cover her black lingerie. But it was too late as Moondancer brought her hands to Rarity’s black underwear.

“Rarity? Did you have a date after our session?” Moondancer waited for the subtle yet clear shake of Rarity’s head for the dickmare to continue. “Oh my goodness, then can I assume you were hoping for something to happen between the two of us?”

“That’s…not…” Rarity gulped as she removed her hands from her bra and underwear, more openly presenting herself as she turned around and moved her own tail to the side, exposing her fat diamond-flanked ass as she shook it up and down. “Does it look cute on me?”

“You cannot be asking me that,” Moondancer chuckled, swiftly bringing her hands to each of Rarity’s cheeks, gripping them roughly but not painfully as she licked her lips regardless of if Rarity was looking at her or not. “You of all mares are one of the most attractive ones I’ve ever had the pleasure of meeting, it's me who was worried about being presentable. Though…”

Moondancer pulled away, jumping off the platform and removing her dark purple dress to reveal her naked body.

“...I like to think my powerful presence more than makes up for it,” Moondancer snickered. “Well, are you interested? Why don’t you warm me up, and perhaps I’ll know your answer?”

Rarity turned around, seeing Moondancer’s dark yellow cock almost fully hard and twitching. Not one to deny such a tantalizing offer, Rarity dropped to her knees and grabbed the dickmare’s length with both hands as she pointed the tip right at her muzzle. Opening her mouth, Rarity lunged forward and engulfed several inches past her lips until the tip bumped against the entrance to her throat. Looking up at Moondancer, who placed a hand on her pristine and luscious dark purple hair, toying with the fashionista’s horn with a finger, Rarity braced herself before moving further down on the dickmare. The overpowering and abundant musk made it far easier for Rarity to deepthroat than expected, getting a lot of Moondancer’s dick in her mouth before slipping most of it out of her mouth. Then, she lunged forward and repeated the motions several more times before Moondancer patted her head.

“Alright, as much as I love your silky mouth, that’s not where I want to cum yet,” Moondancer explained. “Turn around like you did earlier, in front of a desk or table, and bend over with your arms on it. Take off your lingerie too~”

Rarity rushed to her nearby desk, clear of any of her projects for once, before removing her own bra and underwear to let both articles of clothing drop to the floor. She didn’t need to ask why she had to have a place to rest her arms, almost completely certain that Moondancer’s claims weren’t simply talk. She heard Moondancer’s clacking steps from her high heels, the one article of her getup that she didn’t take off, before feeling the yellow unicorn woman’s hands slap right onto her cutie marks. Yelping, Rarity barely processed the feeling of Moondancer’s dick against her wet cunt before the dickmare plunged right in. Moondancer must’ve known from all the context clues Rarity left that the fashionista would already be wet enough for the taking. Working with a taller and stronger unicorn lady such as Moondancer left Rarity to her own building desires even before she knew she was working with a dickmare. That was only one giant bonus to the fun that she didn’t think she would get to have.

Rarity’s eyes rolled to the back of her head as she pressed her arms firmly against the desk, making sure she could handle the surprisingly thick sensation of a mean futa dick straining her insides. Mostly with ease, Moondancer already had half her bitchbreaker inside Rarity while keeping her hands on the fashionista’s ass. She was tempted to try and hilt the prissy little unicorn, but knew that with somepony with as long of a dry spell as Rarity’s, Moondancer had to build up to such an achievement. Pulling out most of her length until only the tip was inside, Moondancer gritted her teeth as she thrusted half her length back inside the fiery hot warmths of Rarity’s pussy. Rarity spread her legs further apart, and once Moondancer moved her hands to the fashionista’s hips, she moved her own hands to her diamond cutie marks to part her ass further apart. The invitation not being more clear, Moondancer snarled as she repeated the motion harder, nearly knocking Rarity into the wall behind the desk. Rarity felt her mind spinning with such euphoric goodness, never having experienced even a fraction of such maddening pleasure from her past flings. The loud PLAP PLAP PLAP of Moondancer railing Rarity’s cunt while her balls got very close to the fashionista’s clit was riling her up in all the right places, and Rarity even let go of her own ass to try and meet the dickmare’s thrusts. She needed to be hilted by this magical beast, so she stopped restraining herself as she brayed to the heavens, throwing her bubbly marshmallow ass back to get properly hilted. Moondancer growled, slapping one of Rarity’s ass cheeks before taking the daring plunge, surging forward and hilting her entire length into Rarity’s vaginal walls with little difficulty.

What Rarity wasn’t entirely aware of was Moondancer using a magical spell to make sure she didn’t hurt the fashionista when hilting her. Sure a little pain was all well and good, but too much and they wouldn’t be having fun anymore. Instead what would’ve been pain simply turned into more pleasure, and Rarity’s voice raised an octave in her scream as she saw stars in her vision. Her tongue lolled out of her mouth as she let out the most unladylike sounds while marecum gushed out of her gaping cunt filled with futa cock as the messy mare juices sprayed out from around Moondancer’s dick and balls pressed up against Rarity. Moondancer stared at the sight with her jaws dropped, and her erect dick twitching inside of Rarity as she discovered just how truly Rarity wanted her length. Not wanting to waste the opportunity, Moondancer pulled out half her length from inside Rarity only to slam the rest back inside. Her balls hitting Rarity’s clit this time, Moondancer watched as with a few more thrusts, Rarity gave a slightly softer cry before more marecum gushed out of her. Moondancer had learned before that fucking mares during their first orgasm easily led to their second, and maybe even third if she timed it right. Then, watching Rarity so easily cum had gotten to Moondancer, as she realized she was about to blow her load as well.

“Tell me to pull out,” Moondancer grinned as she tested Rarity, knowing what the fashionista would say in the peak of such orgasmic pleasure. She wouldn’t think clearly, not entirely anyways, and sure enough Rarity’s pussy clenched around Moondancer’s dick as she answered.

“NO!” Rarity insisted. “You better fill up your teacher with your hot spunk!”

Hearing the word teacher, and recognizing Rarity as a few years older than the young dickmare, unlocked a fetish deep inside Moondancer that she didn’t even realize. Moaning with the much deeper tone of a powerful dickmare, Moondancer hilted herself inside of Rarity before emptying her balls into Rarity’s hot demanding cunt. Rarity groaned and gasped, letting out loudly feminine squeals as her legs quivered. And the best part?

The night was far from over…

“OH YES! PLEASE, MORE, I’LL DO ANYTHING!”

Of course Moondancer would hold her to that best she could, but for now, it was all about cementing Rarity’s place beneath her both figuratively and literally. This time, not half an hour after she creampied Rarity the first time, Moondancer had her slightly older darling mentor on her own bed. While Rarity was no Rainbow Dash, she would be getting a proper leg stretch as Moondancer had her hands on the fashionista’s ankles while having her pinned down in a mating press. Every few seconds, as Moondancer was pistoning her thick cock in and out of Rarity’s needy pussy, she would give the white-furred unicorn’s legs a break as she let go of her ankles to play with her tits. A much enjoyed upside to fucking Rarity in a new position, Moondancer grabbed fistfuls of her pillowy fat breasts and twisted her dark grey nipples until the slutty fashionista yelped and whined from the touch. Her eyes were practically rolled to the back of her head the whole time, gripping the bedsheets of her mattress for dear life as Moondancer moved her dick out of Rarity’s gaping cunt to stuffing her entire bitchbreaker back inside. Rarity watched as Moondancer switched from Rarity’s nipples back to her ankles, reasserting her mating press as she railed the fashionista’s pussy even faster.

“I still can’t believe you’re, fuck, single,” Moondancer panted as she kept clapping Rarity’s fat ass with her lightning quick thrusts. “With breasts like yours and an ass like yours? Though no pathetic little partner you might’ve had would’ve stopped me from shooting my shot…”

“Please ahn! You s-should shoot your goopy shot in me!” Rarity begged, trying and failing to reach Moondancer’s breasts as she watched them slightly jiggle with each vicious thrust the yellow unicorn woman made inside of her. From Rarity’s perspective, watching Moondancer’s dark yellow cock with its prominent veins and thick feeling being present inside her hot wet insides, pistoning in and out of her like she was a fleshlight, drove her wild. She started to welcome the roughness in a way she didn’t think was possible, wanting Moondancer to stick around to fill her up again and maybe even grab her horn and hair in the future. Rarity was slightly aware beforehand just how degenerate she really was, but just with nopony to play with. Now with Moondancer’s balls hitting her ponut this time in the new position, Rarity wanted to ensure she got knocked up this time if the first time didn’t quite do it. She couldn’t give up this dick regardless of if Moondancer was simply into her for a fuck or something more, so she clenched and moaned louder in hopes that Moondancer would claim her again.

“Fuck! You clench like a slut too!” Moondancer grunted, staring at Rarity as her tongue lolled out of her mouth. Her once pristine makeup was coming apart as well, black splotches underneath her eyes as she was profusely blushing from the sensation of being so unapologetically fucked into a mess. Moondancer was spurred on, knowing what the both of them wanted as she briefly moved a hand back from Rarity’s ankle to give the bubble butt a hard smack before bringing her back to the mating press position. Her balls slapped Rarity’s ponut a few more times before she hilted Rarity’s cunt with her entire futa dick. Rarity howled as the two came together, the fashionista’s marecum splattering all over Moondancer’s dick and the bedsheets underneath them. Meanwhile, Moondancer grunted as ropes of her hot white seed once again surged into Rarity’s fertile pussy, some of it overflowing onto the bed as well. Having been pent up for some time now, it felt good for the dickmare to finally get some relief, and especially inside such an attractive unicorn woman such as Rarity.

Pulling out, her cock becoming flaccid again after a few seconds, Moondancer admired Rarity’s barely conscious O face and messed up eyeshadow, on top of the sexual fluids slowly pouring out of her gaping cunt in a lewd concoction. Yes, they would definitely be doing this again…
