Estrus is Quite Pleasant, Really
Rarity,
Sorry for bothering you while you’re in Canterlot, but I need a favor. I haven’t heard from Moondancer in a few days, and I’m starting to get a bit worried about you. I was wondering if you could go to her house and see if everything is alright. I promise, I’ll pay you back later!
Your friend,
Twilight Sparkle
P.S. Moondancer has a tendency of not being open about her feelings. If you can sense anything might be off, feel free to press the issue.
This was the message that Rarity received that morning in a letter marked urgent. No doubt, Twilight was having a royal freakout over her friend’s absence which may not even be that serious. Still, checking in on Moondancer wouldn’t take too much time, so she planned to do it as soon as finished the day’s work. Once done, it didn’t take her long to end up in front of the mare’s home. It wasn’t hard to find, being the only house in the whole city that didn’t look… Well, up to par was the nice word for it. Still, she held her tongue as she made the gentlest knock on the door.
“Hello? Is Moondancer’s home? I am here on behalf of Twilight-”
“TWILIGHT??”
Rarity jumped back in fright as the door suddenly swung open and she was met with Moon Dancer’s slightly manic expression staring back at her. After a few seconds, she calmed down and shook her head. “Oh. I thought you were… Ahem.” Moondancer cleared her throat. “You’re Twilight’s friend, yes?”
Rarity recovered in an instant, nodding and holding a hoof to her chest. “Why yes, darling. Rarity, owner and proprietor of Carousel Boutique. I am here on behalf of Twilight to see if everything is okay.”
“Okay? Um, y-yeah! Yeah, everything…” Moondancer took a huff and adjusted her glasses, her face red. “Everything is fine. Just… Peachy.”
Rarity wasn’t fully buying it. Moondancer definitely seemed to be hiding something, with the way the unkempt mare couldn’t keep eye contact with her for more than a few seconds. Plus… The disheveled appearance in and of itself was throwing her off. Was she simply depressed? Well, she knew one way of fixing that, and that was a fresh new look!
“Darling, if it’s alright, may I come in?” She leaned in slightly. “If there’s anything that is troubling you, I would be more than happy to assist you.”
“U-Uhhh, well…” Moondancer gave a step back, trying her best not to meet Rarity’s gaze.
“Please…?” Rarity whined in a sweeter tone, tilting her head and fluttering her big eyelashes up at her. It was a killer move that affected even the most stone-hearted stallions, and the nervous nerd was no better as she was left with a wobbly smile and stepping aside.
“S-Sure… Come on in…”
“Why, thank you dear,” Rarity nodded, not without a little pride in her acts of seduction as she stepped inside. Once she was in, she gasped. If the exterior was quite the mess, then the interior was something that seemed straight out of a home renovator’s nightmare. Not even the Apple Family’s barn was quite this disorganized and messy! Even still, Rarity held back her tongue, masking her disgust with a smile. “Why, this room certainly looks… Unique! A true scholar’s home, one might say!”
“Eheheh, yeah… It’s a bit of a mess. B-But I’m gonna clean it soon, I swear!” Moondancer squirmed as she looked down. “C-Can I interest you in some water?...”
“Why yes, darling. That sounds lovely.”
Moondancer slowly trotted off to get some water, leaving Rarity to look around in hopes of figuring out what was wrong with the mare so she could leave. It was bad enough that she had to be stuck in such a filthy home without this odd lingering scent in the air. Did Moondancer forget to bathe…? She wandered to the well-worn couch nearby, where a book lay rested on the hoofrest.
“The Night Tales of Somnambula…” Rarity read the title out loud, tilting her head. Out of a slight curiosity for the contents of the book, she hoisted the book to inspect it more closely, gently flipping it open the moment she saw a dog-eared page. What she saw made her eyes become wide as saucers.
Mares. Mares in hot coitus, bouncing on large cocks with faces contorted in utter bliss. Mares tied in silk and leather bondage, trapped forever in an orgasm as they were thrusted into. Some were whipped, some were whipping. Some were in utter subservience, some in total dominance. There was text on each page, but it didn’t matter. All that Rarity could see were the images of hot sex. She couldn’t believe what she was seeing as she sat down, more of that smell flying up in her face and making Rarity’s face become hot. Th-This filth is what Moon Dancer was doing?? she thought as she tried crossing her hindlegs. At that point, everything was starting to become clear. The isolation, the sweaty, unkempt appearance, and that smell… It wasn’t from not washing. It was estrus.
Because Moondancer was in heat.
“H-Here you go, Rarity. Here’s some wa-”
SMASH!!
Rarity’s head zipped to the sound of glass breaking to see Moondancer standing at the kitchen door, panting softly as her gaze locked on the mare’s body. When she looked down, it was clear what she was staring at: Rarity’s big, erect cock, which had gotten aroused while she was distracted by the book.
Yelping and stepping backwards with an even bigger and more nervous expression, Rarity tried to hide her cock with an illusion spell as she spoke. “W-Well, this was quite fun! It is good to know that you are okay, I shall let Twilight know immedia-!”
CLICK
Rarity looked back at the door and tried turning it, but the knob wouldn’t budge. Before she tried, more locks appeared on the doors and snapped shut, trapping her inside. She could feel the geek’s gaze at the back of her head (more specifically at her large balls), and without ceremony, burst into a sprint to try and get away as quickly as she could. Moondancer quickly gave chase, huffing with her cheeks a bright red and drooly tongue hanging out.
Try as she might, Rarity wasn’t able to find an exit, no matter where she looked. Perhaps it was the scent still lingering in the air, but her ability to think was becoming harder, alongside the shaft between her legs… And it was in this time that she had gotten grabbed by an aura and flung through an open doorway, where she landed back first onto stained bedsheets with her cock flying in the air.
“Th-There’s no need to worry, Rarity…” Moondancer huffed as she slowly mounted onto the futa mare. “It’s so simple… All you gotta do is shove that big, nasty pole in my burning hot cunt and blast a few hot loads, and I’ll be all better…”
“M-My pole… I-I mean penis, is not nasty!” Rarity blushed with a huff, squirming at the smell radiating off of Moondancer. “A-And I simply can’t! A proper mare shouldn’t have relations in such conditions!”
“Ohhh, but you know you want to… I mean just look at me…”
“I said, n-!” Rarity’s protests were suddenly cut off as when she returned her gaze to give Moondancer a stern glare, she was suddenly caught in this oddly… Entrancing gaze. She was so busy averting her gaze before that she failed to notice the mare’s horn light up. Now, she was staring at these oddly… Beautiful eyes. Beautiful, glowing, and a bit… Swirly… “N… Nuh… Uhhh…”
“Shhh, that’s it… Just stare, deep into my gaze… Slowly relax and let your body slowly sink back into the bed…” Moondancer whispered, leaning in to brush her body against Rarity’s. She could feel her guest’s pulse slow down while her own sped up, licking her lips as she never broke eye contact for a second. Soon, their lips were pressed together in a hot, passionate makeout session, Moondancer moaning as Rarity’s tongue moved on autopilot in her mouth. As a result, she pressed her moist cunt against Rarity’s snout and began grinding on it. “Just stare deep into my eyes… Breathe my scent, let it become part of you… Let it fill every crevice of your brain, and push everything else down, down, down into that cock…”
“M-Mmm…” Rarity mumbled, nuzzling her snout into the cunt as her tongue once again moved on its own and began to lick away. She should have stopped this, she should hate this, but… She couldn’t look away, from Moondancer and her beautiful glowing eyes, the spirals in her irises pulling her deeper in. Everything her brain seemed to get quieter and quieter with every breath she took, and Moondancer was just so… Beautiful… Sexy… She needed to obey…
Her breathing became more synchronized with Moondancer’s grinding, her tongue slowly swirling around as she took big huffs of estrus which made her cock jump and become harder and twitchier, aching to slam into something. Her wits seemed to melt away like snow in the spring, her body burning for release, for some sort of climax to satisfy her needs. And the only mare she could think of, the only mare that was even in her foggy brain, was the geeky mare riding her snout and locking eyes with her.
Soon, Moondancer slowly rose from Rarity’s face, juices dripping all over the poor mare’s face and ruining some of her makeup. “S-So, Rarity…” She mumbled through small gasps. “Who do you want to fuck… And rut… A-And obey… L-Like a good pet…?”
“... Y… You…” Rarity mumbled back, drooling as she lied back.
“You, what…?”
“You… Mistress…”
“Good mare… Now, why don’t we show some proof of that…?” She giggled dreamily, licking her lips as she moved onto her hooves and trotted to a drawer. Opening a shelf, she whipped out a collar with a blank tag and a leash attached to it. Rarity didn’t even think about why Moondancer had that, mostly because she couldn’t. Instead, she simply lied there as Moondancer used her magic to slap the collar on her and carve out Rutity. “There we go… A much better name for a pet who thinks with her cock, don’t you think, Rutity~?”
“Yes… Mistress…” Rarity mumbled, blinking one eye at a time. She was barely paying attention as her cock and balls ached for release, leaving her tense and unfocused. She needed something… Something to rut.
Seeing how desperate Rarity was to fuck, Moondancer giggled and began running her tongue up and down the length of the cock with kisses and licks until she reached those large, churning balls. “Mmmm, your old self is just being churned away in this big, beautiful sack… I know you’re just so eager to empty it all out in your mistress, aren’t you?”
“Yes, Mistress… I want… To empty myself… In you…”
“Well then, you’re going to have to let Mistress take charge…” With a fluid motion, she hoisted herself on top of her slave, the large cock sliding comfortably between her ample cheeks. She licked her lips as she began grinding up and down, but the moment she saw Rarity try to struggle upwards, she put her hooves down on her shoulders and pushed her back down on the bed.
“Oh no you don’t…~ You’re staying right there…~”
Her hot breath beat against her slave’s neck as she began stroking that massive dick with her cheeks, feeling every twitch and movement that she had. She watched as Rarity’s face contorted in pleasure, attempting to take the lead and hump to her delight. However, Moondancer would slam her hips down and keep her pet right where she wanted her. She wasn’t allowed to take the lead here. Pets followed orders.
She continued to grind up and down on the shaft, getting off to the feeling of the hot rod against her moist pussy, which conveniently lubed up the shaft. Never once did she break eye contact with her slave, even as she raised her ass up high and pressed the flared tip against her nethers.
“Ready, Rutity…~?”
“M-Mmm… Y-Ye-”
“Don’t care~”
WHAM!
Rarity didn’t get a chance to speak. She didn’t get an opportunity to utter a moan. All she could do was lie there, paralyzed and staring into the eyes of her mistress, as she slammed her hips down onto her cock. Her mouth was held open in an attempt to moan out, but this was quickly smothered by Moondancer leaning down and pulling the poor unicorn in a deep kiss.
As her hips swung up and down, Moondancer’s tongue swirled about in Rarity’s mouth, wrangling the mare’s tongue, which moved around trying to keep up. For poor Rarity, it was so hard to focus on one thing in this state, with her stiff cock being ridden so hard and yet unable to cum. The wet, estrus-laden caverns that consumed it gripped on it tight as it slid up and down, each bounce leaving strings of juices connecting Moondancer’s body with her own. With every bounce, her brain sparked with activity, her vision getting fuzzy and less focused as her eyes seemed to become faded in detail.
Moondancer slowly broke the kiss up, a string of drool connecting their mouths while never stopping her barrage of bounces blitzed against the brain of the bewildered Rarity, which began to short circuit amid the rough fucking and began to cry out to cum. Her cock pulsed inside of Moondancer as a moan escaped her mouth. “G-Got to… C-Cuhhhmmm…” She moaned as the precum spilled out and her seed traveled its way up her shaft.
“Oh no, you don’t~”
FLASH!
“A-Ahhhhh~!”
Moondancer quickly caught the sensation of Rarity trying to cum, and before she got the pleasure of doing so, the well-read mare cast a spell on the cock and balls she was using as a personal dildo. A marking resembling a lock with her Cutie Mark had now appeared on the balls of the fashionista as she suddenly found herself unable to release no matter how hard she tried. Her cries of pleasure began to sound louder, more whiny, and far more pleading as Moondancer looked down with a look of sadistic glee.
“Haaah… Ehehehe… Do you like it, Rutity…~?” Moondancer giggled pervertedly, never breaking her rhythm as she slammed down more roughly. “It’s a little something I was researching and even did a little bit of testing on…~ Never got to seriously use it to now…~ How’s it make you feeeel…~?”
“FUCK FUCK FUUUUUCK~!” Rarity shouted out, her eyes wide as she began to drool, thrusting upwards more animalistically. “LET ME CUM LET ME CUM LEEET MEEE CUUUUUM~!”
“Ah ah ah~ You’re not gonna be cumming any time soon! Not unless I say so…” Moondancer leaned in, eyes glinting in delight. “And Mistress says no cumming until you submit to me, and become my dumb…”
SLAM!
“Obedient…”
SLAM!
“futa…”
SLAM!
“fucktoy…~”
Even in her lust-drunk state, a tiny part of Rarity’s mind was doing her best to break through to the rest of her to resist. Push her off, escape, do anything! That part, however, was becoming smaller and smaller as more of her mind was seeding territory to an endless white fog that clogged her synapses in its thick, milky static. Nothing seemed to matter but pleasure, and pleasure only came when she satisfied… Mistress.
“I…” Rarity huffed out. “I-I’ll do it…”
“Hmmm~? Do what now?” Moondancer grinned wider, leaning her ear against Rarity’s snout. “Say the whooole thing…~”
Rarity’s dried mouth forced out the words, most of her fluids having turned to drool that fell out the side of her mouth. “I-I will… Be M-Mistress Moondancer’s… D-Dumb… Obedient… F-Futa… Fuck… Toy…~”
Moondancer practically came right then and there, juices spilling out all over Rarity’s lap and forever staining it in her scent. However, that didn’t even come close to slowing down Moondancer, who used her magic to fondle and squeeze at the tender testicles of her new pet. “Gooood toy…~ Now, tell Mistress… What is your name…?”
“It’s… Rutity…~”
“Perfect~” Moondancer grinned, snapping a collar around the neck and tugging on the leash attached to it. “Now, fill me! Fill your mistress and give her everything inside that sack!!”
Rutity would obey. She did not know how to disobey. All she knew was fucking and her Mistress. Her upward thrusts became harder and harder as precum began spilling out in preparation. The cum built up by her endless fucking finally began shooting up her rod, pleasure striking at every inch of her body. No amount of strength could be conjured to slow down, and even if she wanted to stop it, nothing in her body was responding anymore. Her muscles were locked and tensed up, her back was arched, and her cock was pushed all the way inside of her. All she could do was feel as her eyes rolled up and her mouth hung open as buckets of baby batter blasted Moondancer’s womb, her mouth uttering the most unladylike of groans in all her life…
“U-UUUUUOOOOOOOOOOOOOOOGH~!!”
“AAAAAAAAAAAAHHHHHHHHHHN~!!”
Moondancer gurgled in delight as she was filled to the brim, her stomach slowly filling up with that perfect seed. She was on cloud nine and not coming down for a long time, pulling her pet into a massively wet and tongue-filled kiss. And her pet returned it without hesitation, her old self now gone, lost forever in the pussy of her mistress…
~~~
Twilight would get a letter from Rarity saying that everything was alright and that she would be gone for a while handling business while promising to be back soon. Little did she realize that Rarity’s business was underneath Moondancer’s fat plot, eating her out as she was used as a chair for her mistress. The days were a blur of sex and cum-drinking, never leaving or doing anything but what Mistress wanted. When she wasn’t fucking her or serving as furniture, it was listening her talk on end about the things she learned, which Rarity would respond with slow nods. Sure, she didn’t understand, but she didn’t need to. Breeding pets didn’t think, after all.
She would slowly be released from Moondancer’s ass as the mare stood up, but Rarity still attempted to lean in to get more tastes of that wonderful snatch. Still, she sat there, waiting for orders from Mistress while her eyes slowly scanned around her. During it, she caught a glimpse at the “mare” she was now.
Her cock was now twitching and painfully erect no matter how much she fucked; her balls were now swollen, a pair of enlarged sperm tanks that no concealing techniques could hide; her cutie mark was crossed out to the point where she herself couldn’t even remember what was on it; her makeup was now left stained across her face, not a trace of it removed since she got there and simply left to run; her mane and tail were left matted and unkempt, her mind unable to conjure any ways to fix it save for chopping it into a shorter style; and her eyes, now left hollow and dull, as marecum dribbled out of her mouth.
For Rarity, it would’ve been the most horrid sight, something akin to a nightmare. But for Rutity, it was her life, a blissful dream she never wanted to wake from…
