Pie away on my Zephyr

April 3rd, two days after April Fool's Day and every mare in Ponyville went into heat. Every mare locked themselves away in their homes while all the stallions made their way to town hall, where the mayor had already prepared a list of all the stallions who were on call to provide relief and pleasure in the way any stallion could and also what mare they happened to be paired up with that year, one such stallion was none other than Zephyr Breeze. Zephyr wasn't usually one to stay in one place, let alone Ponyville, though on this occasion he had just landed a job at Ponyville spa and was crashing with his sister... at least until she had to kick him out as her estrus began. All the stallions were gathered round, some of them happy with their allocated mare, some not happy and some who didn't really care either way about it.

Zephyr found his name and when looking to see who he was paired up with, he was disappointed to find that instead of his ideal partner in the form of a certain technicolor pegasus mare, he was instead tasked with having to tend to her weird pink friend, Pinkie Pie. Zephyr never really had much luck with the ladies, so in a way it was lucky that there now existed a system where he was guaranteed to get laid every year without having to worry too much about commitment, though he'd never been given the chance to actually fuck the one mare he had a crush on and would gladly settle down with if she just gave him a chance! Alas, it was not to be this year, so Zephyr started lazily heading to Sugar Cube Corner. After walking in and ignoring the rather loud sounds Mr and Mrs Cake were making while they were rutting each other silly in the kitchen, Zephyr went up the stairs and knocked on Pinkie Pie's door, which was flung open and then promptly closed as Zephyr found himself being dragged into the room by a very excitable and very horny Pinkie Pie.

Pinkie Pie, with a very wide grin on her face, looked at Zephyr and said "Hey Zephyr, so you're the stud who's gotta pound my pretty little pink pussy this year huh? I gotta say that you're probably the most handsome stallion I've had yet! I hope you're packing something better than the stallion I had last year! Still having no luck with Rainbow Dash huh? I think you've gotta let her go dude, she likes stallions just fine but she's more into mares, loads of ponies think that bisexuals like both genders equally split down the middle fifty-fifty but that's not true at all! With Rainbow Dash it's like ninety-ten with ninety being mares and ten being stallions, I've got a fluid sexuality which just means I like everyone! Sex is sex, am I right? What about you big guy? You straight or bi? I only ask becau-"

Zephyr pushed his hoof against Pinkie's mouth to shut her up, he knew that he often came off as obnoxious and annoying but at least it was only in small bouts, he wasn't constantly annoying in the same way Pinkie Pie was... at least he hoped he didn't come across that way. Zephyr sighed and said "I'm straight and no, no luck with Rainbows. I'm not super jazzed about this, so can we just get this show on the road? Stallions who think that having sex with a mare every year is glamorous but it really isn't, especially since we don't have a choice, the only real good thing about it is the commitment side of things. So how you wanna do this?" Zephyr removed his hoof from Pinkie's mouth and allowed her to talk, hoping she wouldn't just prattle on too much and get to the point, he disliked the estrus season mainly because he thought it wasn't very fair on mares or stallions... though he'd probably change his mind if he were finally given the chance to show Rainbow Dash a good time, which was most likely the real reason he was always so pissed off and against the whole estrus alleviation initiative.

Pinkie cleared her throat and said "Well, you don't have to worry about the whole commitment thing, I got a contract for that. Also, even though this is meant to be for my benefit, I don't mind taking things slower than I'd like and to do some things that are just for your benefit. Call it my way of showing appreciation for what you're about to do for me, alright hot stuff?" Pinkie swiftly produced a quill and a commitment contract, something that Zephyr didn't know existed until now but so long as it meant he didn't gain Pinkie as a girlfriend, he didn't care. After both he and Pinkie signed it, Pinkie put the contract away in a drawer and simply went "So, my pussy is burning up right now but I want this to be about you as much as it is about me m'kay? So before you go anywhere near my marehood, would you like a blow job?"

Zephyr raised his eyebrow, no other mare he had serviced had ever offered to do something that was for his pleasure and his pleasure alone, they were usually far too wound up for any version of foreplay and would just pounce on him and focus on making him hard enough to penetrate their sopping wet folds without looking at his face or saying hello. Confused but pleasantly surprised that Pinkie didn't immediately demand that he cram himself into her cunt, he asked "Really? You don't want me to just throw you down on the bed and have my way with you or anything? You're willing to suck me off and hold back... just for fun?"

Pinkie nodded and replied "Sure! For obvious reasons I'll want you to blow your load inside my foal factory but I'll happily let you fuck my face, It's fun! I'll even let you take me in the butt afterwards if that's your thing, anal sex really appeals to the amount of kinky in Pinkie!"

Zephyr was astounded, either this mare wasn't as horny as the rest of them or she really did just have a strong enough will to not immediately view him as a tool to eradicate the heat. With a shrug, Zephyr went over to the bed and lied down going "Sure, I suppose having my dick sucked would be nice and relaxing, not to mention it will make me hard a lot sooner!" Pinkie giggled and trotted over to the bed, trying to ignore her aching cunny as she hopped up next to Zephyr before getting her first look at his member...... it was fucking ENORMOUS. Even flaccid, Pinkie could tell that Zephyr definitely had something to be proud of between his legs, he wasn't quite as large as Big Mac but Big Mac's cock was just proportionate to his body size, Zephyr on the other hoof was sporting a length that looked to be almost to big for his body to wield properly. Zephyr smirked and stated "Yes I know, it's big. It's the other reason why I was surprised you were offering to suck it, not many mares are prepared to wrap their lips around my monster cock, they find it tricky enough taking me in their cunts"

Pinkie's puffed up and desperate pussy lips only got more soaked at the sight of such a beast, this monument to the pure and raw primal masculinity of a stallion, the wild earthy smell of his musk making her folds quiver with want and elation... she just had to have it. Initially, Pinkie didn't have any trouble fitting Zephyr's pony pole in her mouth and playfully rolling his soft stallionhood around in her cheeks, then he started to become erect, going from soft to stiff in a matter of seconds while Pinkie found herself in the rather bizarre situation of a thick throbbing wang lengthening to a point where it continued to grow down into her throat! Pinkie was no stranger to deep-throating, most stallions considered her a sort of maverick when it came to taking as many inches as possible down her gullet, it was just the way it was so suddenly forced upon her if she were to keep all of Zephyr's rigid rod firmly stuffed in the warm and wet confines of her moist mouth, her muzzle pressed into his crotch.

Zephyr let out a sigh as he felt Pinkie swallowing around his fuck stick while she gently moved her head back and forth, making sure not to make herself gag and expel the phallic intruder, if she pulled off of Zephyr's wang now, she wasn't entirely confident that her superior sucking skills would be sufficient enough to cram his dick back down her throat in its entirety. Pinkie kept it simple yet stimulating, fellating Zephyr eagerly and drowning herself in the scent of his plump and heavy balls, just full to the brim with the sweet life-giving seed that would vanquish the prickling heat in her nethers, that thick hot load that would fill her womb and allow her some form of reprieve from the torturous burdens of the breeding season.

Zephyr did feel the slightest twinge in his mind that was tempting him to cave in to his instincts and start humping away at Pinkie's face, though he silenced that voice in his head because he knew that even someone as expertly well-versed in the art of fellatio as Pinkie Pie would have trouble when trying to milk his disco stick with her moist tongue and rippling throat muscles. Zephyr spent the next couple of minutes enjoying the blow job and admiring Pinkie's rather fat bottom before going "OK Pinks... I'm about ready to mount you and end your heat, ready?"

Pinkie pulled herself off of Zephyr, gasping a little before hoarsely replying "Ready" and getting into position, all fours, front half down, ass in the air and tail flagged, ready for sex. Zephyr took a second to truly appreciate the pillowy pink pony posterior in front of him before he heard Pinkie say "Oh, party balloons are on the desk by the way, we wanna be safe don't we?" Party balloons? Zephyr only realized what Pinkie meant when, out of curiosity, he went to the desk and found a wide array of condoms, small, medium, large and XL. Zephyr picked up an XL condom and tore open the packet before awkwardly sliding the slippery latex item down his dong, fully erect and protected, Zephyr turned back to Pinkie, now he was ready to party!

Zephyr returned to the bed and immediately mounted Pinkie, hooking his forelegs around her foal-bearing hips. Pinkie's breath hitched as she felt the warm weight of a stallion on her back, though she gasped a little louder when she felt what was very obviously the head of Zephyr's cock pressing at her entrance, years of mounting mares had clearly given him superb aim, a very handy skill to have for the mares that were often too impatient to wait. Zephyr tightened his grip and heaved himself forward, pushing his way inside Pinkie's hot and horny horse hole and boy... never had the words hot and horny been so appropriate. Pinkie wasn't the tightest mare he had ever fucked, that honor went to the young mare he had the privilege of deflowering during her very first heat. It wasn't the hottest pussy he had ever fucked either, that title belonged to the one pony most stallions would kill to have sex with and that Zephyr had been lucky enough to earn, Princess Celestia herself.

The trouble with virgin mares and with Celestia, is that they were too tight and too hot respectively. The virgin Zephyr had bagged made it exceedingly difficult when it came to squeezing himself into her tight cunt and being able to thrust in and out properly, while Celestia's god-like folds were so hot that Zephyr felt like his cock was being bathed in the kind of warmth that made him want to relax and fall asleep, akin to the kind of feeling he'd had during snowy nights in winter when he'd cozy up in a blanket near a fireplace with a warm cup of cocoa, not exactly the best feeling when you were meant to be pounding a princess. Pinkie pie however, felt divine, exquisite even... who was he kidding? She just felt PERFECT. The warmth of her insides felt like her body was welcoming him like his junk was looking for shelter from cold weather, not as hot as the dick-melting furnace of Celestia's pussy but that was a good thing, his cock felt like it was being warmed up in a soft manner, ironically like when he had found himself getting slightly hard from the heat of the sun when at the beach.

The tightness was equally satisfying, she wasn't so loose that he felt like he was throwing a hotdog down a hallway but she also wasn't so tight that he struggled to make any progress at all, her pussy hugged his erection and clenched around it periodically as if to encourage him, like her body was saying "Go on Zephyr! You go ahead and fuck this mare! You big hunk!" Pinkie was in a similar state of her opinion of Zephyr, his cock was, dare she say... PERFECT. It wasn't the biggest cock she had ever taken, the stallion with that little claim to fame was Big Mac, though for her tastes, Big Mac was actually too big for her to properly enjoy... but Zephyr was of a size where she could feel the delicious way his turgid length stretched her out and filled her completely but not in a way that was painful, it hit that sweet spot where her flexibility was put to the test but not in an uncomfortable way.

When Zephyr bottomed out and they both took a moment to appreciate how well their genitals complimented each other and were both perfectly compatible, he started to actually fuck her. Zephyr was, surprisingly, a rather gentle lover in comparison to other big and burly stallions who rutted mares silly, his thrusts were careful and measured, making sure to deliver an experience that struck the balance between treating a mare like a mare while also leaning very much into the carnal lust of the act. Zephyr, despite Pinkie's pussy perfection, didn't make much noise besides some heavy breathing as sweat rolled down his forehead with a reddish hue tinting his cheeks, there was the gentle clapping of hips against Pinkie's bouncing beautiful buttocks too but the most noise actually came from Pinkie herself.

Usually, Pinkie was the most energetic and frenzied mare you could ever meet but in this instance... the fact that Zephyr matched everything she wanted in a sexual partner kind of mellowed her out and she just maintained her position while making soft moans with every subtle movement of the stallion on top of her, the sex was pleasurable and intense but it also made her feel like she was getting a massage, she'd never felt sex like this before. The sex continued at a constant and consistent pace, neither of them were in any sort of rush or hurry to end such magnificent sex, an activity which was often adequate at best during the heat season due to some stallions and mares just not meshing together ninety percent of the time. Pinkie had reached a point where her face was just as red and sweaty as Zephyr's when Zephyr said "Alright Pinkie... you ready? Your heat's gonna stop in like, three seconds!"

Pinkie groaned and went "Yes! Yes! Fire your party cannon into my party cave! Squirt your cream into my pie! Put a bun in my oven! Mix your milk with my egg in this pre-heated bowl!"

Despite Pinkie's ridiculous baking puns upon reaching orgasm, Zephyr slammed himself home and came, filling the condom with his thick spunk and, as intended, the warmth of his load tricked Pinkie's body into thinking that insemination had taken place and that the chances of fertilization were likely enough that the heat was no longer necessary, ceasing. Zephyr pulled out, removing and tying the condom before discarding it in a nearby bin, Pinkie's heat may have stopped for now but it would only be twenty-four hours before it started up again, that was the whole reason stallions had to stay with their mare for the whole season, they had to have sex with them at least once a day to stave off the heat. Pinkie sighed and proclaimed "Whew! Now is that a relief! I can finally do more than just stay in my room thinking about sex! Well, until tomorrow I guess but I have you here for that! Though I suppose I have enough horny left for a bit of personal fun, whaddaya say big guy? Wanna go raw and stick that thick piping bag full of frosting in my cake?"

Zephyr, not quite getting the innuendo, asked "What?"

Pinkie rolled her eyes and replied "Do you wanna fuck my ass?"

Zephyr, realizing the proposition, exclaimed "Really? I mean, yes! I'd love that!"

Pinkie smirked and got into position, allowing Zephyr to mount her once again. Anal was not at all a new concept to Zephyr, Pinkie was not the first mare to ask him to go in through the back door, though it was thanks to the mares who had asked him that he took quite a liking to pumping a perfectly proportioned plot and it was always a special treat to be paired with a mare who not only was OK with anal sex but was actually into it as an activity to be enjoyed. Zephyr took more care with his aim this time, it was rare for a mare to willingly offer up her booty to be plundered, so he had to make sure that he didn't accidentally slip himself inside her cunt in an effort to penetrate Pinkie's pronounced pucker. Luckily his cock hit the mark, in his haste to enjoy some anal sex he hadn't thought to ask about lubricant, it was only when he managed to enter her tight behind that he understood why lube wasn't necessary.

Aside from what he expected from anal sex, tightness, warmth etc. one thing he hadn't expected was that, oddly, Pinkie's innards seemed to almost tug on his member upon penetration like it was trying to pull him all the way in, prompting him to just go "Whoa..."

Pinkie giggled and said "It's quite something huh? My butt just loves dicks, the only thing it craves more is cum and I haven't yet been fucked by a stallion who's been able to fill my seemingly bottomless bottom! Go on, empty your cum-filled nuts into my cum-guzzling guts!"

Zephyr wasn't about to deny such a polite request and so he eagerly hilted himself in Pinkie's rump, pausing to enjoy the feeling of every inch of his meat spear being enveloped in the confines of Pinkie's dump truck derriere, then start hammering away with gusto, the cheeks jiggling from the force of his thrusts while his swinging fuck sacks slapped against her moist mare folds. Pinkie made a series of unintelligible noises as love hearts filled her crossed eyes, her tongue hanging out from an open mouth grin that conveyed nothing but pure pleasure. Zephyr took the time to land a few smacks across the ass he was currently balls deep in and not even the relentless spanking brought Pinkie down from cloud nine, in so much ecstasy was she that she was certain that at some point she experienced some kind of minor out of body experience just because her mind and body were struggling to cope with it all. Zephyr soldiered on, immersing himself fully in the experience and the sensations, selfishly indulging every whim of his desires with the wobbling globes of flesh that made up Pinkie's glutes.

With scrunched eyes and gritted teeth, Zephyr rammed himself as deep as he could, his cock pulsed violently and the head flared with sexual anger as he thoroughly drained himself in Pinkie's rotund rear. It was only after Zephyr's orgasm died down and that he pulled out in exhaustion that Pinkie was brought back to reality, she somehow always forgot just what being fucked in the butt did to her, especially when it came to stallions with such impressive equipment to really plumb the depths of her incredibly insatiable dick-milking back entrance. The only thing that might have made it any better is if Zephyr had tugged on her tail a little, then again they had a whole month of sex ahead of them, so he had plenty of chances to do it. The rest of the month carried on much like every heat usually progressed, during the day Zephyr would tend to Pinkie's needs whilst also getting to enjoy some non-heat related sex, there would be the odd idea to help keep the sex interesting like different positions and a couple of costumes Pinkie had stashed away from previous events such as nightmare night, every day it was sex, sex, more sex and if they got a little bored with sex, they'd just have some sex.

Eventually the end of the heat season arrived, Zephyr had fucked Pinkie's heat away for the last time and the following day the heat didn't return. When midday rolled around and Pinkie didn't feel the slightest hint that her reproductive organs were going to going to kick into overdrive again, she went "Yay! The heat season is over! Thank goodness, the heat is so gosh darn inconvenient! It's only good for babies and I'm not ready to be mama Pinkie yet!"

Zephyr chuckled and said "Yeah, I don't think I'm ready to be daddy Zephyr yet either"

Pinkie grinned and went "Glad you agree! So, now that the heat's over, what do you wanna do? Wanna go out for a meal or something? Talk about something other than sex or heat?"

Zephyr raised his eyebrow and asked "Why do wanna go out for a meal with me?"

Pinkie replied "Well, that is what boyfriends and girlfriends do usually, isn't it? Especially on a first date, don't think that just because you've been banging me for a month that I don't wanna start dating properly you big silly head! What shall we do for our first date? Watch a movie?"

Zephyr, slightly scared, went "Whoa whoa whoa Pinkie, I don't want a relationship out of this, I told you from the beginning that the only thing I enjoy about the heat is the lack of commitment and we signed that "no commitment" contract thing, remember?"

Pinkie gasped as she said "Oh my gosh Zephyr, when you said you liked the commitment aspect of the heat I thought you meant that because you were having sex with so many mares, it was nice to know that you could commit to some pony you met when paired up for the heat! I thought you were asking me out! That contract was an agreement to date me for a minimum period of six months, after a six month period the relationship may continue but may grow to include marriage and children upon discussion, terms and conditions apply!"

Zephyr went pale, simply going "Was... is that contract legally binding?"

Pinkie, rather sheepishly, nodded before stating "Yeah... we can't exactly go back on it..."

There was a deafening silence before Zephyr just shouted "FUCK!"

later -

"Look, I don't know what you're complaining about, the sex was good wasn't it?" Pinkie was trying to deal with the aftermath of accidentally becoming Zephyr's girlfriend when he had made it quite clear that he wasn't interested in commitment... unless it was Rainbow Dash.

Zephyr sighed "The sex was great Pinkie, trust me it was the best sex I've had with any mare ever, it's just that I wasn't looking for a girlfriend, Alright?"

Pinkie pondered for a moment and went "Would it help if I dressed up as Rainbow Dash?"

Zephyr deadpanned and said "Pinkie be serious...... I mean the answer is yes but I'm not gonna make you do it! Besides, we're in it together now and I'm pretty sure that as good as the sex is you probably wouldn't really want me as a boyfriend"

Pinkie, confused, replied "Seriously? I think I'd really like you as a boyfriend! You're creative, you can do things really well if you put your mind to it, you got that rough rugged look about you. I don't care that you fancy Rainbow Dash, it's not like she'll ever say yes anyways and finally... you're not too bad in the sack if the last month proves anything" and winked. Zephyr was surprised to say the least, he had gotten so used to people not wanting him around that the concept of a mare knowing who he was, liking who he was and wanting more of who he was just baffled him to no end, he knew he was an obnoxious loser so why was Pinkie so into him? Did he really possess the qualities that she had just listed? He couldn't be sure about it.

Pinkie could see the hesitation in his eyes and said "Look, like you said, we're a couple for at least the next six months, why not try it out and see if you enjoy it? If after six months you decide it's not for you, we'll part ways and you can go back to fucking your way through every mare around once a year until finally getting paired with Rainbow Dash, deal?"

That was a reasonable enough request, Zephyr nodded and went "Alright, deal!"

Things started off relatively tame and Zephyr struggled to get into the spirit of things, especially when Pinkie Pie introduced him as her boyfriend to the rest of her friends. Twilight was confused because she assumed them to be incompatible, Rarity thought that Pinkie Pie deserved better, Applejack assumed that something nefarious had taken place for this improbable relationship to happen and Rainbow Dash thought Zephyr was just using Pinkie to get closer to her. Fluttershy seemed to be more jealous than anything for some reason. Despite their negative opinions, they accepted the relationship and... at the very least tolerated the fact that it seemed to be genuine in nature rather than something else entirely.

It was at the three month mark that Zephyr actually warmed up to the idea of Pinkie Pie being his girlfriend, he liked spending time with her and began to find the mundane activities they did together one of the more enjoying aspects of his life, it certainly helped that her friends were no longer suspicious about him and treated him friendlier than before, even Rainbow Dash was happy to say hello to him. Pinkie Pie made him happy and the more time they spent together, the more they found out how much they actually had in common, Pinkie Pie had managed to get him a job which he promised to stick to and just like before, the nights where they had sex where mind-blowing despite Pinkie's mistake of trying to get food involved.

it wasn't until five months in that Zephyr actually accepted the fact that he wanted Pinkie to be his girlfriend, he never realized the value of having a partner that he could depend on for support in times of need, whether emotional or financial, Pinkie was there to help him. Nightmare night rolled around and they'd had a great time doing all of the usual things, a little trick-or-treating, bobbing for apples, the apple family maze, they had plenty of fun though Pinkie had decided to tone down her usual quirky costume ideas and went as a witch while Zephyr dressed up as a werewolf. When the night was over, they went back to Pinkie's place and although Zephyr hadn't moved in yet, they were already calling it "home" or "our place".

Pinkie sat on the bed and went "Aahh... it feels good to be back, did you have a fun night?"

Zephyr joined her and said "Yeah I did actually, probably one of the most fun Nightmare nights I've had ever since I was a kid! I'm about ready to hit the hay to be honest!"

Pinkie gave an exaggerated pout before going "Awww... really? 'cause I was kinda hoping that before we go to bed we could do something romantic together... like have a quick fuck?"

Zephyr perked up and replied "Well, I suppose I could stay up a little longer"

Pinkie giggled and asked "What hole on my body do you want honey? My mouth is sore from that apple bobbing thing but the other two are good to go! What you in the mood for?"

Zephyr smirked and went "Considering that tonight is all about fun, I think it should be obvious about which one I should go for, wouldn't you agree?"

Pinkie blushed as she said "Oh Zephyr... I... you know what anal sex does to me, don't you?"

Zephyr nodded, Pinkie always went into a comatose state when having her ass fucked, like her body was so sexually stimulated that it simply couldn't cope with it and would just shut down temporarily, not to mention her butt could never seem to get enough dick inside it. Pinkie, feeling very bashful, whispered "Shall I... k-keep the costume on? To be sexy?"

Zephyr chuckled and asserted "Pinkie, you're plenty sexy enough for me... but yes, keep the costume on. You get into position and I'll lube us up, I know your butt is so greedy for cock that it's not really necessary but there is such a thing as too much friction, alright?" Zephyr removed the bottom half of his werewolf costume to free his slowly hardening erection while Pinkie got on the bed before sliding her stockings and panties down her legs, sticking out her fat butt and waiting very patiently, goosebumps rising along her skin with great anticipation.

Once Zephyr was sure his rod was nice and slick, he coated Pinkie's puckered ponut before casting the lube aside and mounting before asking "Is the witch ready to be my bitch?"

Pinkie smirked and replied "So long as my big bad wolf is ready to bury his bone, I'm game"

Zephyr grinned and started pressing the head of his cock at her back door, his aim having improved drastically after having a horny girlfriend for longer than just the estrus season. Zephyr started pushing forward and just like before, the second he managed to sink his tip past her ring, her ass began to pull on his boner insistently, silently urging him to keep going. Zephyr had stopped questioning why Pinkie's butt seemed to have a life of its own and was always eager to be filled but he was all too happy to oblige and launched himself balls deep, not even his medial ring stopping him as he started hammering away at his girlfriend's ass. Pinkie's eyes rolled rapidly in her sockets, her girlish squeals of delight echoing off the walls as her face adopted an orgasmic grin, her tongue practically rolling out from her mouth cartoonishly while she drooled uncontrollably. Zephyr could feel Pinkie's pulsating pussy already winking and soaked as his fat nuts clapped against her cunt, she was almost there.

Seconds later and the unending climax that Pinkie always experienced during anal sex began, her moans intensified as her pussy practically exploded, gushing fluid and soaking everything nearby, her thighs, the bed, the mighty stallion currently pounding her silly... then of course, she had that signature out of body experience again, like her soul had ascended beyond the realms of pleasure and had left temporarily to witness the beauty of her body being railed so savagely from behind, in her behind! She only came back down to earth when Zephyr rammed himself as deep as he could and unleashed a torrent of jizz into her bowels, painting her insides white, he would have engaged in some spanking but his hips had already done a decent enough job of that and the costumes had already ticked off the added kink factor box. The only thing on both their minds when he pulled out, was to sleep.

the next day -

Celestia's sun poured into the room, forcing Zephyr and Pinkie to abandon their plans of having an extended sleep. Once they had both gotten up, removed their costumes, cleaned up, eaten some breakfast and thrown the dishes in the sink, Pinkie turned to Zephyr and said "So, I guess this is it huh?"

Zephyr went "Huh?"

Pinkie continued "The relationship, it's over right? The whole commitment thing, it's been six months, you're free to go! No more Pinkie and Zephyr, we're single and ready to not mingle!" Zephyr realized what Pinkie meant and rather than feeling happy about it... he was actually disappointed, he hadn't expected to form a connection with any pony the way he had connected with Pinkie Pie, he'd gotten accustomed to her presence and he had actually forgotten that this was a temporary commitment... he wanted more, no... he needed more. Pinkie looked at Zephyr's face and went "Zephyr? What's wrong? You don't seem all that happy. Aren't you happy that you can just go back to banging a random mare once a year?"

Zephyr looked to Pinkie and admitted "Actually... no, I don't want that anymore Pinkie. I want to be your boyfriend, I've changed my mind about commitment and the one I want to try commitment out with is you, you like me for me, you helped me get a job, you helped me make friends... I don't want that to go away, I need you in my life Pinkie, please..."

Spikes and Stripes

Zephyr didn't know what reaction he was expecting but he was still surprised when he found Pinkie squeezing him to death in the biggest hug she had ever given him ever, once she released him and allowed him to breath she planted a big kiss on his lips and just shouted "Yes! I'm so glad you changed your mind because I really really super duper love being your girlfriend! Now this means that I can introduce you to my family on Hearth's Warming!"

Zephyr smiled before what Pinkie had said registered and then, slightly panicked, asked her "Wait wait wait, hold on a second.... your family?!?!"

two months later -

As Zephyr walked with Pinkie to her old family home he went "Is this really a good idea?"

Pinkie rolled her eyes and went "Relax! They've lived here on the rock farm for their whole lives but they're not any different from "regular" ponies! Just be yourself and it'll be fine!" When they got to the door, Maud was waiting there to greet them, prompting Pinkie to say "Hiya Maud! I want you to meet my boyfriend Zephyr! Ain't he just the dreamiest hunk ever?!"

Maud stared at Zephyr vacantly while he smiled and sweated nervously, one slow blink later she said in as monotone a voice as Zephyr had ever heard "I've heard a lot about you from my sister... she says you're good in bed, especially with her butt... thanks to your really huge co-"

Pinkie interrupted going "Maud! Don't bring up the super secret embarrassing sex stuff I mentioned to you in private! What if Marble and Limestone hear?!"

Almost as if on cue, Marble and Limestone appeared from behind Maud, Limestone stating "We already know Pinkie, you don't keep secrets very well. You're just lucky that mom and dad haven't heard you bragging to Maud how your new boyfriend has nuts so big that he actually makes you feel full when he blows his load down your throat after you suck him off"

Pinkie and Zephyr blushed so hard that their faces practically turned crimson, Marble remained ever silent, Maud remained stoic, Limestone was somewhere between happy and angry for some reason... the only thing that broke the ice was when Cloudy Quartz appeared and said "Zephyr, lovely to meet you. Please do come in, Igneous has made rock soup!"

They all followed after Cloudy while Pinkie whispered to Zephyr "I'm sorry about that, my family are nice ponies they're just... kind of quirky and a bit old fashioned, it'll be fine!" Zephyr was seriously beginning to doubt his ability to handle this situation but he couldn't exactly back out now, in any case he would have to meet the family eventually if his relationship with Pinkie was ever gonna work long term, it kinda sucked that Pinkie already knew his parents through Fluttershy, she wouldn't have to go what he was about to go through.

As they all went into the dining room to sit down, Zephyr came face to face with the most terrifying family member any stallion would have to face when dating a mare, the father. Igneous was... slightly intimidating, his long sideburns and no-nonsense demeanor made him seem like he could be reasonable so long as you stayed on his good side but could easily pummel you into the ground if you got on his bad side, so Zephyr wasn't completely at ease. Zephyr sat down and saw that this famous "rock soup" looked to just be a rock sat in some oddly colored water... hopefully he could stomach it enough to be polite and say it was nice. Igneous sat directly opposite and went "Aahh, you must be Zephyr Breeze, the young stallion who helped my daughter with her estrus and then decided to date her shortly afterwards"

Cloudy shot her husband a look and said "Igneous, don't be so rude!"

Igneous shrugged and replied "Well it's true isn't it? I didn't say that he's only dating her for sex, I'm assuming he's had plenty of sex with countless mares on account of the E.A.I right?"

Limestone interjected and clarified "Dad, it's what you're implying that's the problem, not what you're saying. The only reason Marble and I don't get any action is because we live on a secluded rock farm, if we lived in Ponyville then stallions would be sent to cure our estrus"

Igneous couldn't fault his daughter's logic and went "Fine, I apologize if I seemed cold towards you Zephyr, hopefully you can understand that, as a father, I'm somewhat selective about who I allow to court my children. Anyway, I say we tuck in before the soup gets too cold, enjoy!" The conversation briefly abated, much to Zephyr's relief as they all began to have their soup which was actually surprisingly good and borderline refreshing, it must have been the mineral content in the rocks that added a special flavor to the more liquid part of the soup. Halfway through the meal Igneous piped up again to ask "So... Zephyr, on the subject of my daughter... do you intend to make an honest mare of her at some point?"

Pinkie gasped, going "Dad!"

Igneous rebutted "Oh come now Pinkie, it's a perfectly reasonable question! Zephyr?"

Zephyr decided he needed to be careful with how he answered, he didn't want to offend his potential future father-in-law so he thought for a second, what would a stallion who was clearly rooted in the old traditions want to hear? Zephyr replied "Well... if and when the time comes that Pinkie and I decide we might get married... I would ask your permission first"

Igneous seemed to accept that answer, quite gracefully considering that Zephyr didn't actually state outright that he would definitely marry Pinkie, though it wasn't long before Igneous asked another inappropriate question "So what do you do for a living Zephyr?"

Again, Cloudy chastised her husband "Igneous, don't pretend that you're not just trying to find out his financial situation! I'm sure he makes enough money to provide for Pinkie and what's more important is that they connect emotionally!"

Igneous rolled his eyes and said "Well of course they connect emotionally, they wouldn't be dating otherwise! Though if you insist that I don't be polite with my line of questioning then fine, let me rephrase. Zephyr, how much money do you make in your job per hour?"

Zephyr gulped and nervously admitted "Uh... sixty-four bits so... just above the minimum..."

Igneous, again, accepted the answer and seemed adequately alright with the fact that while Zephyr wasn't exactly raking in gems on a daily basis, he was at least earning more than the bare minimum wage of some other jobs, it wasn't a lot more but it was still decent enough.

Everyone finished their soup and after the rest of the day went without any more awkward conversations, the pie family were all getting ready for bed... except Igneous. While the rest of the family were getting ready to hit the hay, Igneous turned to Pinkie and Zephyr before going "You two, could you join me outside please? There's something I would like to discuss"

Zephyr and Pinkie looked at each other with concern, had Zephyr messed things up somehow? Did he not live up to Igneous' specifications of what he deemed to be a suitable partner for Pinkie? Neither of them had any idea what to expect and feared the worst. Once all three of them were outside and a decent distance away from the house, practically in the middle of a field, Igneous turned to Zephyr and said "Zephyr, it is very clear to me that you care for my daughter. You care for her emotionally, financially and that if this relationship lasts... you would intend to be with her and continue to support her on a more permanent basis and that is wonderful... however, one thing remains to be seen in my opinion"

Zephyr and Pinkie remained silent, simply waiting to hear what more they needed to prove. Igneous took a deep breath and stated "Zephyr, I know that you and Pinkie have been intimate, though I must ask you that... for the purpose of having foals... could you breed my daughter properly?"

Pinkie was mortified and went "Dad! What kind of question is that?!"

Igneous, remaining serious, said "Are you saying that he can or that he can't? I'm not talking about sexual pleasure or emotional intimacy, I'm talking about the simple and very natural process of getting a significant other pregnant, he needs to show me that if you two ever decide to take that step, that he knows how to do it in the right way!"

Zephyr cut in to ask "Hang on... show you?"

Igneous nodded and explained "Yes, believe me it gives me no pleasure whatsoever to ask you to do this or for me to see it, it's not a performance it's more of a... demonstration. I'm going to stand here and watch while you fuck my daughter as if you were intending to impregnate her... this is an uncomfortable thing to ask you to do I know but I can't, in good conscience, allow you two to carry on with this relationship if you aren't good enough for her"

Pinkie was blushing harder than she had ever blushed before, she knew that her dad was just speaking from the heart and was doing this from a good place, it's just that she felt embarrassed that she would have to give her father such a unique perspective. Seeing no real way out of it, Pinkie simply tapped Zephyr on the shoulder and when he turned to look at her, she had turned away from him to shake her hips from side to side, waggling her bubble butt in front of him in a silent plea to take her right then and there.

Zephyr couldn't believe this was happening, he had to show Pinkie's dad that he knew how to have sex with his daughter correctly for the purpose of having children! Was there right way? Zephyr focused on Pinkie's erotic display and thought through what he had to do as his cock slowly hardened, Igneous was old-fashioned, traditional, no-nonsense... how would he fuck Cloudy if he wanted children? What was the "natural" way to breed? Then it clicked... Zephyr knew what to do to impress Igneous, he didn't just have to fuck Pinkie, he needed to RUT her. He had to be instinctive, agressive, horny beyond belief and he couldn't hold back, he had to be rough and not delay his ejaculation in any way, he had to fuck like a savage wild animal! With that in mind, when he was fully erect he mounted Pinkie and shamelessly crammed the entirety of his dong into her foal factory.

Pinkie couldn't help but let out a very surprised moan, after catching her breath she just went "My goodness Zephyr... you've never been so vio- aah!" Pinkie didn't get to finish her sentence as Zephyr almost immediately began to piston away at an alarming and almost frightening pace, never before had he thrusted so quickly and so strongly before, grunting through gritted teeth while Pinkie continued to moan uncontrollably from how fervent and feverish her boyfriend was fucking her. Igneous was watching with mild interest, his face not conveying what he thought of the sight before him, he simply stared, still and silent.

Pinkie's butt quaked more than it ever had before, one ripple of flesh started before the other had finished and the cheeks themselves were turning a shocking tinge of red, Pinkie's whole body shook as Zephyr pounded the living daylights out of her as if he would never get to fuck her again and considering that he was working under the scrutiny of her father, there was a real possibility that he might not actually fuck her again, so he went all in. Pinkie gave a silent shriek when, out of the blue and surprising even to herself, her cunt just gushed her female fuck fluids in one of the strongest orgasms she had ever had... though still not quite on par with the orgasms she had experienced during anal sex. The moist warmth of his girlfriend's cunny squeezing his shaft and soaking his member only gave him the incentive to double his efforts despite how fast his own climax was approaching.

Zephyr's hips ached in protest, his eyes scrunched up tight before he simply bellowed like a beast and pushed himself as deep inside Pinkie as he possibly could and unleashed a veritable tsunami of spunk, pumping what must have been the fullest and thickest load he had ever produced... though again, anal sex still came out on top in terms of pleasure. They were both breathing heavily, though Pinkie yelped when Zephyr pushed her face to the ground and started drilling her cunt again, mere moments after having already cumming inside her. Although Igneous didn't show it, even he found it interesting that Zephyr was presumably still hard enough, energetic enough and pent up enough to go for a second round. Of course, considering that Zephyr was still so sensitive from his last climax, it was barely two minutes before he busted his nut again, flooding Pinkie's chambers with a smaller and less impressive load than the last, though apparently enough to trigger a mini orgasm from her.

Zephyr pulled out and dismounted, completely drained and exhausted, with Pinkie in much the same state. Igneous cleared his throat and went "Zephyr, that was an... exotic display"

A twinge of fear ran through Zephyr's spine, had he misinterpreted something and completely fucked up? That fear only went away when Igneous finally cracked a smile and calmly said "Good job, I would say you're perfect for my Pinkie Pie, come, let us all get some shuteye!"

Meanwhile............

Stallions made their way to town hall where the mayor had already prepared a list of all the stallions who were on call to provide relief and pleasure in the way any stallion could and also what mare they happened to be paired up with that year, that was how it usually went. One year however, stallions were surprised to find that Spike the dragon had decided to attend. As he was walking to where the list was a stallion went "Hey Spike! On the list this year huh?"

Spike grinned and said "Yep! Mares around here need all the help they can get, besides I don't wanna get into another situation like last year"

Curious, the stallion asked "What happened last year?"

one year ago -

Spike breathed heavily as he held his back to the front door, sweat rolling down his body, he had barely made it out of the golden oak library intact thanks to a very horny Twilight Sparkle and had unfortunately had to lock her in for both of their sakes, he could find something to occupy his time with in town... for a month, hopefully. Twilight banged on the door from inside, practically snarling and frothing at the mouth as Spike heard her muffled voice go "Come back in Spike! It's your job as my number one assistant to do as I say! So get your scaly little ass back in here and FUCK ME! I'M IN HEAT AND I NEED YOUR COCK NOW!!!"

present day -

Spike shuddered and replied "Ugh... I won't talk about it, it's why I had the mayor include me on the list from now on, so I can get out of the library to avoid repeating that fiasco"

Spike made his way over to see who his first mare would be, in the past he had stayed with Twilight during the estrus season which is why he hadn't done this before, though last year's heat hit Twilight particularly hard and after it was over she was actually the first one to suggest that maybe he should participate with all the other stallions just in case. The only reason Twilight nearly assaulted Spike during the breeding season of the previous year was because the stallion who had been selected to pleasure her hadn't arrived as quickly as she would have liked and the anticipation of sexual relief had left her stressed and impatient. After looking at the list, Spike was disappointed to find that he was not tasked with pleasuring a certain fashionista that he was enamored with but was instead tasked with the one and only Zecora, the only zebra that lived anywhere near Ponyville, what was worse was that her home was in the rather dangerous Everfree forest which was a scary place to visit even in broad day light.

Spike would have tried to see if he could swap with the stallion who was lucky enough to get Rarity but unfortunately, swapping was against the rules. The mayor created this list and attributed every mare a stallion, even herself, which made the list a legal document so technically, any stallions who swapped mares were breaking the law and it would be treated as a punishable offence. Spike sighed, Zecora wasn't unattractive in any sense, he was just hoping that he would finally be able to satisfy the mare of his dreams, not this year it seems.

Spike began walking to the Everfree forest, trying to ignore the wails of ecstasy coming from Fluttershy's cottage as Thunderlane railed her senseless, ready to visit Zecora and spend the rest of the month ramming his dick into her hot Afriquestrian cunt and filling it with warm jizz. The journey through the forest was eerie and it made Spike feel very vulnerable to be so alone, though he soon found himself at Zecora's home, she may not have been Rarity but Spike wasn't exactly gonna turn down the chance to be balls deep inside a sex-crazed zebra. Spike knocked on the door and seconds later it opened to reveal the smiling face of Zecora as she went "Why it's Twilight's dragon friend, Spike! Please come in and sit down if you like"

Spike allowed himself in and accepted Zecora's invitation to sit down on a nearby chair, taking a moment to observe her home. From the outside it looked interesting what with the carved wooden faces adorning the trunk of the tree she had made into a house and the inside was just as interesting, several objects that were most likely from her homeland of Afriquestria were everywhere, countless shelves contained bottles of different objects and strangely colored liquids that were no doubt used as ingredients for whatever foods and remedies she cooked in her cauldron in the middle of the room, which was steaming and filled with some sort of odd concoction at that very moment... it was oddly comforting. Spike cleared his throat and said "So Zecora, I imagine you know why I'm here right?"

Zecora nodded and, in her thick accent and compulsion to speak in rhyme, replied simply "Yes, to cure my heat with help from your seed but let me tell you that there's really no need"

Spike seemed confused and asked "What, you don't think I'm capable or something? I'm not a virgin if that's what you're wondering, I fucked a dragon girl called Cynder once, a total slut"

Zecora shook her head and explained "No, your sexual prowess is not the reason, I just drink a potion around breeding season. The potion stops me from getting that hot itchy feeling that makes mares find anything cock-shaped appealing, however there is one thing I feel I should mention, being a loner means I don't get much attention...... so though I don't feel the heat or its effects, I still want you here for a months worth of sex!"

Spike, surprised at such a revelation, went "Really? You're not feeling the heat in any way whatsoever but because you live in the Everfree forest you can't get laid... so you let someone have sex with you during the heat month anyway? Why not just let the heat happen if you're gonna spend it having sex with whatever stallion arrives?"

Zecora blushed and said "The heat of a zebra is very strong, it even makes it hard to tell right from wrong. For example, I once tamed a timberwolf so that when the heat hit me, I could cure it with some simple bestia-"

Spike interrupted, he knew where that rhyme was going and didn't want the sentence to be finished, going "Whoa whoa whoa, too much information, I get the picture... well, it's nice to know that you're only a normal level of horny, it means we can actually take the time to enjoy all the constant fucking we're going to be doing rather than rushing it. Anything in particular you want or would you prefer me to get things going?"

Zecora giggled and stated "Spike, I will be doing anything your lust wishes me to do, for the next month my body is belonging to you. You can fuck my mouth, my pussy and my fat jiggly butt, just do whatever you want to me and I'll help you bust a nut. So dear Spike, do you like?"

Like? Zecora was basically offering herself up on a silver platter and telling Spike that she was practically his sex toy for the next month, not only did he not have to use protection because equines and dragons were incompatible but he now had a submissive whore all to himself no questions asked? He didn't like this situation at all, he absolutely fucking loved it! Spike smirked and answered Zecora's question by saying "Yes, I like very very very much! Though before we can enjoy ourselves, why don't you help me get hard? You've already gotten me started but it wouldn't hurt for you to make me fully erect now would it?"

Zecora lidded her eyes and went "My self-imposed obligation, is to provide you stimulation..."

Spike would have stood up had Zecora not started trotting over, looked like she intended to have him stay seated which Spike had no complaints about, if anything it would make the ensuing sex all the more relaxing if he didn't have to put too much effort into it. Once Zecora was stood above him, she began to lower herself down while Spike's dong began to pulse in arousal, was Zecora going to try and get him into her cunt before he was even semi-hard? Spike found the answer to that question when Zecora instead pressed her moist pussy lips up against his tool and started rubbing back and forth, Spike shuddered as he said "Whoa..."

Zecora, slightly out of breath from such an intense feeling, gasped "Yes... my pussy is rather slick... does it feel good to have my folds gliding across the length of your dick?"

Spike, now at full mast, nodded dumbly as he replied "Uh-huh... though how about you stop talking and use your mouth to do something more pleasurable than some simple grinding?" Zecora grinned and started shuffling down Spike's body until her head was between his legs. Zecora stayed silent as she began planting small kisses along Spike's thighs, slowly moving upwards until her lips made contact with his heavy fuck sacks, Spike breathed heavily as she continued to kiss her way up his shaft until planting one final kiss on the head of his cock before slipping it into her mouth and sucking on it as gently as she could. Spike was enjoying Zecora's approach, he had to admit that sometimes building up the anticipation of sex was often better than just skipping the foreplay altogether to get to the main event.

The only problem that Spike had was that Zecora was prolonging the experience a little too much for his tastes, two minutes went by and Zecora was still just tenderly paying all of her oral attention to the tip, he was going to lose his boner at this rate! Spike decided that if Zecora belonged to him for the month then he'd have to take charge a few times until she learned what he wanted in a mare who'd made it her mission to continually drain his nuts. Spike said "Listen Zecora, if you're gonna spend the whole estrus season pleasing me then you've gotta step things up, starting with actually sucking me off properly like a real whore" then grabbed onto Zecora's head, her eyes widened as she felt herself being pushed down until Spike's entire fuck stick was crammed into her mouth. Spike let out a sigh of satisfaction and started moving Zecora's head up and down, letting go once she got the idea and started blowing him the way he wanted her to, making the effort to open her eyes and look up at him in a cutesy way.

Zecora relished the taste of Spike's erection, he wasn't as musky as some of her previous stallion lovers but that just made the natural flavor of his skin all the more intoxicating, not to mention that he was the perfect size, big enough that it filled her mouth but not so long that it ended up being pushed down her throat. Spike sat back and relaxed, his dick as hard as ever and being serviced by a horny zebra, not a bad way to start the month! Zecora didn't do anything differently after Spike had manually guided her to give him a more satisfying blow job but Spike was OK with it because he didn't intend to rush his orgasm, so the way he could feel his climax slowly approaching the longer Zecora kept up her methodical sucking of his pole would perfectly ensure that when he finally came, it would be as pleasurable as possible for them both. Ecstasy would ripple through Spike's very being and Zecora would be treated to a good mouth full of spunk that, if she wanted to be polite, she would definitely swallow.

Spike could feel that he was close to cumming, he groaned "Alright Zecora, I'm close..." to which Zecora responded by carrying on like the obedient little cum dumpster she was. Spike grit his teeth and made guttural grunts as his balls tensed and sent thick ropes of jizz into Zecora's waiting maw. Zecora kept sucking to prolong Spike's pleasure and allowed his nut butter to collect in her cheeks, though she had underestimated just how much he could produce and had to swallow most of it to make way for the rest of his baby batter. Once Spike had pumped as much jizz as he could, Zecora swallowed it all down, enjoying his unique yet familiar flavor and stayed where she was with her lips wrapped around his shaft, knowing better than to move away before her temporary master gave permission. It was basic manners for a submissive to keep a cock somewhere warm and welcoming for as long as possible.

Spike basked in the afterglow of his orgasm and when he felt rested and energized again, he made a "shoo" motion at Zecora, signalling that she was free to remove herself from his throbbing length. Zecora pulled back, allowing Spike's dick to fall from her mouth and saying "I hope that you thought that my tongue felt real good and liked that I swallowed your load like any good mare would. Like any good whore, I am ready for more, so if you are still feeling as if you are in need then I will do what I must to earn more of your seed"

Spike smirked and went "Hey now, what did I say about the talking? Keep your mouth shut unless you're blowing me like there's no tomorrow! Though since you are being so generous, I think so long as you get me nice and hard again I might have another round in me but I think this time around I'll be paying a visit to the other end, know what I'm saying?"

Zecora blushed and nodded in understanding, she had always felt shy about letting stallions have anal sex with her because she knew that she had an exceptionally fat booty, rivaling even the most well endowed of mares in Ponyville, with her ass being so large it made sense that it was also rather sensitive both inside and out... she couldn't guarantee to keep her promise of not talking if she reached her climax while Spike was fucking her sizable rear. Spike, again too lazy to actively participate, went "Alright then, hop to it and get me ready!" Zecora retrieved a bottle from one of her shelves, it didn't contain anything too special, just some warm scented oil that was intended for luxurious baths, though now it was going to be used for something just as enjoyable.

Zecora uncorked the bottle and drizzled a little of it on Spike's cock before turning away and making a show of pouring the rest of it on her wide expanse of ass from one big cheek to the other, Spike's member was already reacting positively to such an erotic display. As the slippery substance rolled down her buttocks she shook her hips to show off how much her booty wobbled before bouncing up and down a little, successfully managing to make her glutes clap, Spike was slowly approaching a semi and Zecora hadn't even gotten to the best part, the part that would prepare them both to get the ass fucking started as soon as possible. Zecora backed up and smooshed her squishy dump truck behind down on Spike's erection, then started moving back and forth to deliver a wet and satisfying butt job, simultaneously also making sure that his prick was lubricated enough that it would easily slide right into her perfectly prepared and pronounced pucker. After a few more seconds of swiveling her rump around in circles on Spike's dick, he was as hard as he could get and ready for action, a fact he communicated quite effectively when he gave Zecora a firm slap on the ass and said "Alright Zecora, I think I'm about ready to find out what the inside of your rear feels like"

Zecora shuddered in arousal, she would have happily accepted a good spanking before the main event but that could wait for another day, Spike wanted in and he wanted it right now. Zecora lifted herself off of Spike's lap, allowing Spike to hold his erect wang and also grab hold of one of her ass cheeks, pushing it aside to reveal her previously hidden back door, licking his lips as he went "Damn, that ass hole looks tempting, maybe tomorrow I'll latch onto that thing with my mouth and get a real taste... though right now I need to penetrate that tight looking ponut and enjoy a nice massage courtesy of your anal walls Zecora, come on..."

Zecora thought that they'd both waited long enough and it was time to enjoy some anal sex. Zecora lowered herself back down, carefully making sure that she was on target so that the head of Spike's cock was pressed against her rear entrance and poised to be squeezed in. After only a few seconds of pressure, Spike's tip slid inside Zecora's butt and slowly but surely, Zecora continued her downward motion to sink every last throbbing inch of his long and thick dragon dick into her tight ass, both of them groaning in ecstasy. The further in Spike was in Zecora's behind the better it felt, her walls were warm and rippled around his length while Zecora loved just how wonderfully full she felt the more of Spike's cock her bottom claimed, filling her in a way that made her feel like she had been empty all of her life and was finally complete now that she was having a cock shoved up her ass.

Zecora began to ride Spike, though rather than slamming herself down on his prick like there was no tomorrow, she was slow and methodical, making sure that for as pleasurable it was to have her rear filled with dragon dick, it would be just as good if not more so for Spike to feel the tightness and warmth of her insides massaging his monstrous cock rather than just being pumped in and out without any regard for how good it actually felt. Spike let out a sigh of satisfaction, the only other sounds being the occasional grunt and some heavy breathing as Zecora expertly milked his member with her rump, both of their pleasure building slowly towards what would be a truly exhausting orgasm for them both. After a minute or so of Spike enjoying Zecora's sensual approach, he reached forward and gripped onto her hips to start manually controlling her movement, increasing the speed and force of Zecora's rhythm.

Once the pattern had been established, Spike let go and Zecora continued with the new pace that Spike had set, her buttocks rippling as they plapped against Spike's hips. It wasn't rough animalistic fucking just yet but it was getting there, Spike's nuts churned with his thick heavy seed while Zecora's cunt got wetter by the second, already winking in anticipation of the impending climax. Zecora's anal walls quivered and Spike's cock throbbed, they wouldn't last much longer at this rate and there was only one way that Spike intended to finish things off. Zecora yelped as she suddenly found herself face down and ass up on the floor, not to mention the fact that Spike was now pounding away at her big fuckable booty like his life depended on his ability to completely wreck her ass hole.

Spike snarled in Zecora's ear "I'm gonna fucking fill your guts with spunk you little zebra slut! My balls are fucking aching to fill your ass with all the dragon seed a whore like you needs!"

Spike's relentless reaming of her bottom coupled with the dirty talk proved too much for Zecora and her sore pussy gushed a frightening amount of orgasmic fluid as she shrieked "Oh nkosi yami! Lokhu kuhle kakhulu ngilahlekelwa umqondo! Sicela uqhubeke! Qhubeka futhi ujezise amafutha ami amakhulu ngemuva!"

Spike didn't understand a word of Zecora's native tongue but at that moment he didn't care, roaring as he slammed his cock as deep into Zecora's backside as possible and emptied his heaving fuck sacks inside her, completely and thoroughly drained of both cum and energy, leading him to fall backwards, his overworked dong slipped from Zecora's gaped rear entrance as he fell into a deep sleep with Zecora following soon after.

The rest of the estrus season continued like this every day, obviously there came the moment where Spike got to slide his fuck stick into Zecora's exquisite cunny, though the fact that Zecora didn't feel any effects of the heat and that the two of them were genetically incompatible anyway, meant they got to try a myriad of different things that were just for fun! Exploring each other's kinks and indulging them a little, though Zecora had been a little hesitant about letting Spike spank her pussy with the spade of his tail in much the same way Spike had been hesitant about jerking her off when she drank a potion that temporarily gave her the necessary equipment. Nevertheless, when the month ended and the heat was over in Ponyville, they parted ways...... though Spike was certainly going to visit her outside the estrus season, the two of them were perfectly matched in regards to their sexual tastes, besides, who in Equestria wouldn't want to regularly hook up with an obedient bitch like Zecora?

The End

Epilogue

Needless to say, the Estrus Alleviation Initiative was a complete success in Equestria, so successful in fact that countries across the globe began to implement it to deal with their own citizens, after all they couldn't have the entire female half of the population accosting every stallion in sight just to make their heat go away for a while, it needed to be organized!

The initiative was a controversial idea when first proposed by world leaders but with no alternatives, it was adopted into many a society and once it was streamlined to ensure that every creature was responsible and wasn't paired up someone who was incompatible, everything was fine! Their was an outcry from the gay community who were displeased that, just for the sake of the estrus season, they had to endure a heterosexual relationship for an entire month... though they didn't kick up too much of a fuss because, unfortunately, even gay mares suffered the effects of the heat and the only thing they could do was suffer through for a whole month or just bite the bullet and let a stallion have their way with them. Not only that but, for the most part, it was somewhat optional for stallions whether they participated at all and since there wasn't a large gay community, their decision to opt out of the Estrus Alleviation Initiative didn't have too negative an impact.

In any case, the truth of the matter was clear, the Estrus Alleviation Initiative was successful and often lead to good things! Stallions could brag if they happened to be allocated to a princess, a stallion and mare might find love, maybe a dragon and a zebra would find... well, maybe not love but certainly a long-lasting lust at the very least! More foals, more marriage, there didn't seem to be too many negative things to come out of the initiative unless ponies were accidentally really stupid.

Zephyr and Pinkie continued their relationship and, despite a few ups and downs, especially when the two families met each other, they eventually did get married and had some foals, two daughters named Flutterpie and Pinkieshy... which they realized later on sounded like they were named after a relationship between Fluttershy and Pinkie Pie that never existed... but they liked the names to much to change them, they'd just have to deal with that problem later on in life.

Spike and Zecora also continued to meet up so that Spike could sexually dominate her and she got all the sex she never got from other stallions, she even stopped seeking sexual comfort from wild animals! Which was lucky really because bestiality was against the law in Equestria, not even Fluttershy could cross that line even if she wanted to despite being able to talk to all of her feathery and furry friends. To cut a long story short, the Estrus Alleviation Initiative... was great!

Thank You PuzzleMaster98 for this story idea! I hope you enjoyed it :)

Prologue

Every year, the mares of Equestria went through one of the most excruciating things they could possibly experience, the only thing ponies thought was more painful was giving birth. Every year during the spring, every last mare in the whole country went into a crippling heat.

The heat season was a troubling time for mares because the heat stopped them from performing daily tasks, if they tried to go about their business, they'd get too distracted and end up sexually assaulting the nearest stallion... which is why the E.A.I had been created.

The E.A.I or Estrus Alleviation Initiative worked on a simple principle, when the heat season began, all the mares would stay in their homes and every available stallion would be selected and paired with a mare to satiate their needs until the end of the season. The initiative was surprisingly successful, every year there were stories of how two ponies had found each other so compatible that they'd get into a relationship, inevitably there were also stories of dumb mares and stallions who failed to use protection and ended up having a foal.

Some of the most uncomfortable stories came from situations where out of control mares had ended up sleeping with a friend or family member out of desperation to end their heat, or the unfortunate circumstances in which gay stallions had been attacked and forced to copulate, it was because of situations like these that the initiative was introduced.

One year, a stallion had begrudgingly become the unwilling boyfriend of a certain pink mare...
