Experiments with Zecora

 

It all started a couple weeks ago. Your thesis in botany for the Cantelot university aimed to inventory and categorize the plants in the untamed Everfree forest. After a review of the state of the art, which mostly revealed incoherent and outdated information all over the literature, it was time for you to begin a long field research mission to fill some of the blanks and right some of the wrongs. You settled in Ponyville in the hope to find a guide to help you navigate in the forest, and the inhabitants were quick to advise you to meet the zebra who was living there. She was also said to be an expert on the matter of your study.

 

The Everfree itself was unsettling, and you had been warned about the reality of its perils, but the only mare living here was a beacon of light and worth the travel alone. Zecora, the nonchalant zebra mare was both a well of knowledge and a model of helpfulness. Perhaps her life as a hermit was a bit boring at the moment, for she decided to invest herself greatly in your works. It became obvious very fast you’d have to credit her as much as yourself for this thesis. Not that it bothered you the slightest. Genuinely as invested in your field of research as you were, finding such a competent pony that sometimes even outmatched the literature in Canterlot by her knowledge alone felt like a godsend to you. Not only that, but she was also qualified to navigate through the depths of the forest and guide you to find and study the necessary specimens that still needed to be documented.

 

It became a daily routine. Unless the specimens of the day needed to be observed at a special hour, you’d travel from Ponyville to Zecora’s hut right after noon, do field research until the sun was about to set, and then spend the evening recording your findings. The forest being more dangerous after the sun has set, it was quickly agreed it’d be best you spent the night at Zecora’s. And then in the morning, you’d come back to Ponyville to secure your research and so both of you could tend to separate matters.

 

This was a fulfilling cooperation from an academic point of view, but you couldn’t help feeling something more eventually. Zecora was a bright mind in a healthy body for sure, and her humble sensuality had allured you before you could realise it. At first you we just focussed on the useful information her stylised sentences contained, but now you found yourself enthralled by the music of her rhymes. You were at first glad your guide in the Everfree was a nimble and surprisingly strong zebra mare, but then it’s the elegance of her moves and the subtle tone under her stripped coat that your eyes couldn’t let go of.

 

Single yourself, you were however fearful to ruin a functioning teamwork and concealed your feelings. Or at least, you tried to. You discovered about yourself that you tend to space out in front of somepony you find attractive. Zecora called you back to attention several times while you were idly staring at her through the days. She showed no discomfort about this, aside from a bit of lecturing on the importance of staying focussed when journeying through the Everfree. Until one day, after calling you out while you were in her hut after the sun had set, she decided to address the matter in a way you didn’t expect.

 

“Would you let me say that your focus tends to slip?” The zebra mare tells you with a gentle smirk.

“Is there anything you need to get past your lip?”

“Ah, it’s nothing important.” You answer embarrassedly. “I guess I’m just a bit of an airhead. Haha…”

“Not important, maybe. Not sure I would agree.”

“Perhaps it shouldn’t be kept from all eyes to see.”

Zecora walks closer to you. Way closer, until less than a foot separates the two of you. Her serene blue eyes stare right into yours, and you can’t look away from them. The zebra mare is a little taller than most mares, and you’re eye-to-eye with her.

“I live alone, but now it is the two of us.”

“I can promise what happens here won’t make a fuss.”

“There are no secrets where trees that fall make no sound.”

“So I ask you, do not be scared, let your heart pound.”

 

Your face feels like it’s burning at this point, but Zecora answers with a kind smile of her own, so you decide to seize her invitation, and step forward to kiss the wild flower of the Everfree. The first of many kisses. First through this night, and soon would follow another novelty as you and Zecora explore each other’s bodies rather than the flora of the forest.

 

The daily routine you had set up with Zecora changed slightly from here on. You now greet each other with a kiss that is often not perfectly chaste, as you both await more eagerly the end of you workload of the day so you may abandon yourselves to each other. Zecora was first as inexperienced as a mare could be, but she is supremely confident in the secrecy of the woods. The zebra mare shows neither shame nor restrain during your experiments in pleasure. In bed, she leads you like a little puppy to do her bidding, but she gives back so much love you cannot imagine a partner more thoughtful than her. While she revels in your fascination with her, Zecora’s a paragon of gentleness. In addition to the raw physical pleasure, Zecora’s openness even on this field pushes both of you to learn about the other, and progress in skill so the next night may be even better than the last.

 

And so that started a couple weeks ago, and tonight the two of you are at it again. In the dim light of her hut, her hot and earthy breath on your face as she moans, her hooves gently draped over your arms, Zecora slowly raises herself up and down your member, helped by your hooves expertly grasping her toned midsection. With all night in front of you, you’ve come to enjoy not rushing the deed, the slow burn of pleasure making the release all the more satisfying, and the cuddling and kissing in between so much dreamier.

 

At some point, Zecora marks a pause. Still penetrated, she comes to hug you and rest her head next to yours. However, you feel her doing something with her hoof. Zecora chuckles softly, and when she leans back on your shaft, she sports a slightly mischievous smirk and has in her hoof a vial containing an earthy green potion of some sort. Under your quizzical glare she swiftly drinks it, and like nothing happened she rides you with more force again. Knowing better than to ruin the mood with questions, you match the movement of your hips to accompany Zecora’s.

 

It took you a little time to figure out the effect of the magic broth. At first, you believed your shaft going deeper inside your lover was simply her going further down on you. Zecora was giggling softly between her moans as you hadn’t figured out her little prank yet, and it went on and on, slightly deeper each thrust, but her chest didn’t descend any lower in front of you. In fact, her blue eyes, clouded with pleasure, seemed to slowly rise like the night stars above. You almost erupted as the realization hit you. Her swan-like neck, freed for jewellery during these times, was longer. Her weight was greater each time her flanks smacked your own hips. Her hooves holding you reached further on your back. Slowly, Zecora was growing in front your enraptured eyes.

 

You never lusted after a mare’s height in the past, but you loved Zecora, and right now there was more and more Zecora to love in front of you. You pounded her with renewed fervour. Hugging her expanding form, feeling in delight her skin pushing your arms back as you squeeze her. Zecora purrs and moans at your sudden surge in need, greatly appreciating the results of her trick. You come not long after, now held close by a mare half a head taller than you.

 

Zecora stopped growing not long after that, but already it felt like you had a new lover in front of you. Gone was the traces of monotony that had accumulated thought the days. You found yourself thrilled upon exploring the new, improved body of the zebra mare, and she too was eager to try out her new possibilities. You both lasted for about an hour longer than usual, stopping only when Zecora’s body shrank down to its usual size. Before that, you had used your mouth to kiss ever inch of her body, you both came too many times to count, and each of you got a few unexpected laughs from the situation, may it be a mare’s body a bit too heavy for the usual licking, or a shelf a bit too low when standing up.

 

Now both of you, tired, await for sleep to wash over you while you’re under the covers, nestled in each other’s arms.

“I’d wager you liked the effects of my potion.” Zecora whispers in your ear.

“Yet this is a drop, soon it shall be an ocean.”

“Tomorrow, I’ll have another concoction ready.”

“I already have plans to spice up our party.”

“You can expect the next vial to be more potent.”

“And with each day, will come a new trick to patent.”

“But I also want you to have a word in this.”

“Tell me, colt, how shall my next potion bring you bliss?”

 

>Input answer

 

After the events of tonight, you dream about Zecora’s face alone filling you whole field of vision already. You mind filled with possibilities, you also ponder about trying it the other way, and ask for Zecora to become as small as a doll next time.

 

But you have plenty of time before considering such extreme size discrepancies. The overall work for your research being far from complete, you have many days and potions ahead of you. A more pronounced size difference will come later. For now…

“How about you get some bigger flanks with the next potion batch?” You offer.

Zecora chuckles in response.

“I did notice your eyes tend to dart on my butt.”

“Very well. You shall get bigger cushions to rut.”

 

After one last good night kiss, you both drift off to sleep.

 

You have trouble focussing the next day. Acknowledging and satisfying your love for the zebra mare allowed you to relieve your mind of most uncalled daydreaming during work hours, but today you look forward to the evening so much you space out even more than you used too. This time however, Zecora is less inclined to call you out for it. Instead, she answers with a sultry look whenever she catches you staring, which does more than merely keep your need intact. Fortunately, you’re passioned enough about your research that you still manage to put out almost as much work as usual. The extensive study of growing Gluteus Maximus and the nearby specimens, as alluring can those can be, shall wait until the night.

 

Yet night eventually comes, and as soon as you’ve packed away papers and quills, Zecora drinks the potion of the day. As the two of you often do, you start with some gentle kissing and groping to put each other into the mood. You get hard faster today as you eagerly anticipate what’s to come, but for the time being Zecora doesn’t seem to grow in any way, leaving your length throbbing impatiently.

 

“You seem to think something is amiss.” Zecora asks playfully.

“Did you expect more around my cuisse?”

A mischievous grin on her face, Zecora leans on the wall and presents you her rump. In proportions, only the princess of the sun herself could rival with the zebra’s bountiful rear. The muscles of her flanks bulge out enticingly at each side of her tail. And yes, muscles. While Celestia’s mound are probably as soft as the cakes she feeds them, Zecora’s ample buttocks are homegrown from the endless peregrinations of the zebra mare in the forest. Only a thin layer of fat covers them, allowing one to clearly feel the pumps and flexes under Zecora’s coat. Still, as beautiful as this sight could be, it is the same right now as every other day.

“Colt, if you’re not happy with my glutes.” Zecora says.

“Give them a slap, and witness the fruits.”

 

These instructions are being quite forward. You approach the zebra from behind, and before getting to the real fun, you start straddling the visibly eager zebra mare. One hoof on her strong back, the other comes to stroke the cutie mark of your lover while you nest your cock between her cheeks. Zecora moans impatiently, and she slowly wiggles her rump while you slide yourself up and down her groin, the wetness under becoming quite apparent. You wait for the right timing to surprise her, and suddenly your hoof that was tenderly kneading Zecora’s flank lashes to land a sonorous slap on the spiral of her mark.

 

Zecora lets out a little cry of mixed pain and arousal while her firm buttocks briefly shake from your assault. The initial surprise in her voice quickly become pure pleasure however, as only a second later her body surges at once with a couple more inches, and her rump bulges out even bigger right in front of you. You’re forced to take a step back as the twin striped mounds swell like provoked pufferfishes, growing outward with flesh and fat, and making your prick sink deeper between them.

“More!” Zecora demands with a cry of lust. “Growing makes me feel such a jolt!”

“Make me and this butt grow bigger, colt!”

 

Zecora asked for more, more she’s gonna get.

You slap her flank again, triggering another surge in size and mass. You find yourself forced to stand of the tip of your hooves to keep your meat between the zebra mare’s expanding buns. Meanwhile, Zecora seems overwhelmed by the effect of her own potion, moaning loudly as each of her buttchecks become wider than her midsection. Far from the firm cheeks of earlier, Zecora’s butt is now sweeling outward with soft fat, and jiggles madly under your hit.

 

You don’t think you’ll be able to even put it in if Zecora grows again this position, but you’re overcome by another desire at the moment. You let go of all restrain, and simply whams the zebra’s butt again and again. Each time you’re rewarded with the mare’s body growing bigger, and Zecora’s cries of pleasure getting higher in pitch. You beating her pillows seems enough to bring her over the edge alone again and again, a puddle of her fluids forming under her expanding rear.

 

When she strops growing, Zecora is probably about a head taller that you are in height, but her buttocks have grown to obscene proportions. There’s a literal wall of ass in front of you, almost reaching the ceiling of the hut and obscuring the rest of the zebra’s body to you. Zecora could probably smother you from head to groin if she sat on you at this point, something you’ll surely experience later tonight. However, while her overall size isn’t increasing more overall when you smack her ass, her body still reacts with a surge of size that recedes down over the next few seconds. And even if the increase of size isn’t permanent, your lover seems to feel just as much pleasure from her body attempting to get even larger.

 

Her rhymes forgotten in favour of senseless exclamations of lust, you force Zecora to lie on her belly simply by slapping her giant butt again and again, overwhelming her with lust. There, you insert yourself between the twin stripped mountains to reach her crotch. Grabbing on her lower back, you’re otherwise surrounded by Zecora’s plush fat ass on both sides. Nothing less that your whole body could have forced these two sweaty oversized cheeks apart to actually penetrate your lover’s entrance. Along your prick, it’s your whole body that you have to pull in and out between the two masses of flesh, only your back legs poking out from this stuffy valley. Encased in her warmth, both you and the oversexed zebra mare cum in no time. After this release, you take your break while still nested in the hot and wet space between Zecora’s buttocks. With a single wiggle of you being enough to tease Zecora there, her impatient moans soon beg you to get back at it.

 

At her size, it could have been easy for Zecora to do whatever she pleased with you, but the huge zebra being more butt than mare, she was turned into a moaning mess whenever you decided to get physical on her massive cheeks. These sensitive twin mountains turned red after a night of abuse, two broomsticks ending up broken in the process of making as much of an impact as possible. Still, you didn’t miss the occasion to be smothered under the soft, massive rear. That’s once box checked on your growing bucket list, but maybe one day you’ll be wholly under this rump without it being disproportionately large in regards to the zebra mare.

 

Like the night before, Zecora eventually ends up scaling down after some hours of hot fun. You’re rather tired yourself, but your partner is a mess after taking so much orgasmic abuse on her behind. She lies limply on the bed, still moaning absently whenever you do as little as to touch her still reddened cheeks. It’s only the morning after that she talks to you again.

 

“I loved it last night, even if it was different.” She says.

“I’m eager to continue through this experiment.”

“Already I have another twist for the next time.”

“Now I also ask you. How can I make it sublime?”

 

You can’t wait for Zecora to dominate the forest with her size. You can think about some beast-like characteristics that would suit her alread. But before that…

“Well, we tried the very rear.” You answer. “So let’s get a bit forward and work on your milk factories.”

 

“A logical choice. You’re one simple colt I see.” Zecora smirks

“So you want milk? Tonight, you shall drown in a sea.”

 

That’s one mouth-watering promise Zecora makes to you here, and you can’t help but to lick your lips in anticipation.

 

After one last kiss until the next, you part ways for the morning, reuniting after noon as per usual.

 

You’re able to concentrate a bit more on your work today. You’re looking forward to the events of tonight, sure, but you’re confident in the fact the reward will only be better the hungrier you are. In fact, Zecora’s the one who’s sometimes a little aloof today. A few times you catch her prodding her rump which is probably still a little sore from last night. The zebra would often look away in slight embarrassment when you caught that. That must have been the first time you see her a bit unsure of herself.

 

Anyway, the evening eventually comes, and after a good day of work, it’s time for the two of you to relieve some stress.

Zecora drinks her potion under your thirsty gaze, and todays the zebra mare starts growing almost instantly after. Letting out a lusty whimper, Zecora’s body expand rapidly, until you find yourself looking right at her chest. From this angle, you also catch a hint of her teats, which have each grown to the size of your head.

 

“Why, don’t you want more than a mere glimpse?”

On these words, Zecora stands on her hind legs, allowing the two swollen black teats to rise at your level. The taut, shining skin makes them near perfect black spheres, only a few visible veins, their slight sag, and the mighty nipples caping them altering their geometric perfection. Already, Zecora is tall enough to touch the ceiling with a hoof in this position, which allows her to give her new trouser-puppies a mighty shake along one of her hips. Entranced, you watch her boobs bounce wildly for a good 5 seconds from this one move, your eyes following the dancing nipples that seem to dare you to approach them. You’re feeling very thirsty all of sudden, and you can’t know for sure whether you imagined that sloshing sound you heard or not.

“My, these really went from shrimps to blimps” Zecora comments amusedly.

“Now come. They’re ready for many sips.”

 

‘Sips’ does not really describe the magnitude of what you want to do with those funbags. You slowly walk to them, befuddled like the first time you had seen boobs. But it was just a picture back them, and one that didn’t suggest such size, such fullness, so much girth as the tanks in front of your eyes.

 

Like in a dream, you bite the meaty nub and smother you head as far as you can in the warm, meaty orb. You trigger a pleased moan from Zecora as a spray of warm liquid erupts inside your mouth. The zebra mare’s milk is unnaturally sweet. On instinct, you start to tug and pull on it with your teeth to get more, moaning uncontrollably as the tasty cream goes down your throat. You feel its warmth spreading through you, making you head spin delightfully, and your raging hard-on feel ready to burst.

 

And that just happens. Your frenzied milk feast stops as you ejaculate spontaneously with a cry of lust from the divine taste of Zecora’s giant tits. Your legs give away under you as your head spins, encased in a soft cocoon of orgasmic bliss. Not only that, but even though you just came, your member lost none of its mast, and you feel about ready to erupt again mere seconds later.

 

Zecora sits next to your lying form, her massive milkers wobbling enticingly as they hit the ground not far from your head. There, the giant mare places a loving kiss on your forehead. Slightly distracted from your obsession with her boobs, you look up at the smile of the huge mare above, who looks like she’s greatly enjoying your fondness of her twin mounds. There, the zebra mare leans to suckle on her own tit, gulping a few mouthfuls with pleased hums.

She stops after some mouthfuls, suddenly looking a little less focussed as her head rises in the air again.

 

“My, this is quite intoxicating indeed.” Zecora comments, speaking with a sultrier voice, but slightly slower than usual for her.

“This shall improve the satisfaction of our need.”

 

“You should drink some more.” You say with an enraptured smile. “I don’t know how you did this, but your stuff really packs a kick.”

“Yes, today was no the day I brewed in restrain.” Zecora chuckles.

“Indeed, let us drink more of this creamy champagne.”

 

There, Zecora bends again to get another taste of her own supply. Moaning with each gulp, a rivulet of white deliciousness pearls from the corner of her mouth. You’re torn between your own wish to drink some more of the mare’s milk, and the desire to have these huge lips suckling on your shaft instead.

 

Zecora rises her head up in the air while uttering one draw-own whimper of lust. Frow the splash you hear around her groin, it seems that Zecora’s milk is just as potent on her than it is on you. Now both feeling the buzz and probably too dizzy to even stay steady on your hooves, Zecora reaches for you with her hooves to give you a hug before slouching on the ground with you against her chest.

 

Follows an approximate making out session. While both eager to kiss the other’s mouth, you both find yourselves missing the mark more often than not in the blur of the influence of Zecora’s milk. Still, you make the best out of it in good fun, a peck on the cheek of the bigger zebra mare turning into a little hickey, or her own lips aiming a little low triggering an impromptu raspberry. You both giggle as much as you moan for a while.

 

At some point, you lie on the larger mare’s body who’s resting on her own back. She’s big enough you can have your back on her belly and squeeze your head between the two warm tits. You feel some sort of horny plenitude with each of your ears smothered against the taut milk bags, snuffing the sounds around you. You caress both of these orbs with your hooves, lightly squeezing them around you head and electing a moan from Zecora, as well as some droplets of warm milk to dribble down their slope. The sight being too enticing, Zecora leans to smooch your face that is still between her boobs. The world around your head is completely occupied by Zecora for a while, cornered by her huge knockers and her lovely lips that you could kiss all night long.

 

Probably allured by the white drops on them, your partner’s attention shifts to her own tits however, and she leaves your mouth to put hers on her wet nipple, getting another serving of intoxicating milk. This time, with your ear against the tit, you clearly hear the liquid flow out into the huge mare’s maw. You hear her moans reverberate through the flesh, and you even hear Zecora’s teeth pressure the flesh nub into giving her more of this creamy deliciousness.

 

You end up feeling the mattress-sized body of the zebra mare shudder in ecstasy under you as this new dose of milk makes her climax again. As this orgasm peers out, Zecora now stares at the ceiling with a blissful expression on her face, each breath coming out of her body as a lust-filled moan. Meanwhile, your own mind’s slowly clearing up, so you reluctantly pick up your head from the comfort of Zecora’s twin pillows to give her a little more. The way she’s lying on the ground, you have a prime access to her entrance, and between the effect of the milk on you, the sight of these marvellous tanks, or the one of the sex-crazed owner of say tanks, you’re more than excited for some real action.

 

And it turns out you don’t even need to permanently leave the comfort of Zecroa’s huge teats. As you align yourself with her crotch, the twin milky mounds make for perfect anchors for your hooves. Not only are you squeezing them to keep yourself in place, but you can keep burying your face between the two black spheres while you rut the huge zebra mare. With those logistics, you start to hump Zecora proper for all you’re worth. Almost instantly her cries of bliss resonate for the whole Everfree to hear. She cums only a dozen seconds after you started, and you follow not long after, drowning you own grunts of pleasure among the sea of Zecora’s teats. And with the effect of her milk, you’re able to resume pumping into her for the next milk-fuelled orgasm to come.

 

You continue like this for what feels like hours. Time makes little sense when one’s mind is addled with pleasure every pseudo-minute. Your attempt to note how many climaxes you experience also fails when the count exceeds a dozen. Zecora remains drunk on pleasure and milk, content with being rutted until the end of the night. She only sometimes decides to take another serving of her own milk to maintain the buzz, but letting you do whatever you wish with her imposing form otherwise. You decide to abstain from the milk yourself. The experience was fun, but you wish to have you whole brain to explore the body of this big, beautiful mare to its fullest. Again, her sight alone is stronger than any alchemic aphrodisiac on your libido already. Zecora’s body looks like a perfect music instrument laid out in front of you, and you want to hear every note she can make.

 

And so you rut her again. Then you drive you shaft between her teats until you cum, while twisting the nipples with your hooves. And after that you have your way with the zebra mare’s ponut. And during all that, Zecora only moans and cums in helpless bliss. Ever single of your touches feels mesmerizingly good to her, so your sometimes rough handling (well, as much as one may roughly handle a mare 5 times heavier than oneself…) only brings her to higher realms of pleasure. Her teats further make sure of this, as they seem to never dry out of dizzying milk for Zecora, who shall chant all night long.

 

This time again, it’s only in the morning that Zecora can make coherent words to ask you again.

 

“These transformations truly are an experience.”

“And tonight, I shall try out a new variance.”

“So my question returns, how do you want to play?”

“Also, if you wish so, the teats and ass may stay.”

 

“I really loved your curves last night.” You answer. “And also those you had the night before, even if …those might have been a bit exaggerated around the end of the night? Anyway if you’re okay with keeping those, I’d be more than happy with it.”

“Good.” Zecora nods.

“I’ll be looking into making effects stable.”

“Then, what novelty do to you want on the table?”

“We’ve been increasing your marely assets twice in a row.” You answer. “How about we give me a bigger package next time? Something you won’t forget for a while, no matter how big you end up yourself?”

“Very well.” Zecora grins. “If my brews do not make you cautious…”

“You shall pack enough to make all colts envious.”

 

Another morning apart allows the zebra mare to prepare tonight’s potion, and after noon you’re back together for some field research in the forest.

 

After one more night of mind-numbing bliss, you feel like Zecora’s the one turning impatient about the upcoming activities of the evening. While you collect specimens in the Everfree, you feel like she never misses an occasion to flaunt her assets to you whenever she gets the chance. Confident that you love her body even while she hasn’t augmented herself yet, a discreet amount of flirting makes its way in the zebra mare’s words and actions. You find yourself being the one advocating for focussing on the task at hoof today. Still, you keep enough distance between work and fun that your research keeps going strong.

 

The time for fun eventually comes, and today there’s one potion for each of you. You have a toast and both drink it down. The strange aromas on your tongue are dull and bitter, but nothing bad enough to make you retch. And once down your gullet, a pleasant warmth spreads through your stomach and into your whole body.

 

The effects are immediately visible on Zecora. The zebra mare stifles a moan as her head rises in the air until she’s about as tall as yesterday, so you’re eye-level with her chest. Her teats also swell to a size similar to the one of the night prior. But tonight, her posterior also significantly gains in girth. Naturally a bit bottom heavy with muscle mass, Zecora’s buttocks now turn into awe-inspiring stripped cushions with just enough softness to jiggle when shaken while keeping a strong core underneath.

 

Now, about you. You expect your shaft to quickly gain some more size to please the huge, beautiful mare in front of you, but for now you only have your regular raging hard on. And as always, that’s not on the potion, but rather a perfectly normal reaction upon witnessing a zebra queen grow into the body of a goddess in front of your eyes.

 

Still, the confident look on Zecora’s face in response to your quizzical one proves this is all as intended, and she’s indeed quick to give you an explanation.

“I envision tonight as a bit of a game.” She starts.

“Listen to the rules so you understand the frame.”

“Your boner is gonna grow bigger from here on.”

“Will come no break nor release lest I make you come.”

“At that point, I will immediately catch up in size.”

“And your shaft will become adequate for my highs.”

“I know your lust aims higher than what we tried yet.”

“So now, I offer we spice things up with a bet.”

“For tonight, shall you come before your length triples,”

“You shall obey my words like the ones of sibyls.”

“Have me grow more than three times my normal,”

“I’ll obey all words, no matter how infernal.”

 

You’re about certain the larger zebra mare is gonna pounce of you the second you take on her bet. Now, of course you’re going to accept her terms, but the question that remain is how you’re going to play this out.

 

 

“You’re on!” You answer Zecora’s dare with a grin. “So if I stall long enough before you can make me come, you’ll do anything I say? To be honest, that’s just a bonus for me. Just having you grow more is reason enough for me to make it last as long as I can.”

 

“Very well. But do I intend to catch you soon.” Zecora smiles in return.

“This game ought not to last until…” But before she can finish her sentence, you suddenly turn and run through the door.

 

“I really mean it, when I say I’m gonna make it last!” You call one last time as you flee into the darkness of the forest. Zecora chases you after only a few seconds of stupor, and you catch a playful grin on her face before she definitely leaves the aura of light from her hut, after you.

 

You gallop through the forest. Having walked these paths enough times, you’re both feeling safe enough to play your little game on these fields. Your pants and giggles break the silence of the woods, the zebra’s heavy hoofsteps thundering not far behind you.

 

However, size plays in your favours here. The trails you tread on are far from being proper roads. The narrowness of the paths, the night and the low branches do more than balance out your erect shaft slapping against your belly as you run, and you manage to put some distance between you and the larger zebra mare.

 

When you’re fairly sure you’re out of view, you walk aside from the path and hide. As much as Zecora taught you how to travel in the Everfree, you’re not gonna win in a game of stamina. You’d also wager she’s gonna get used to her new size rather quickly. A game of hide-and-seek seems more appropriate to win in the long run.

 

And indeed, Zecora passes you while you lie in the foliage, the rapid stomping of her hooves then gets quieter as she moves away. This gives you a moment to see if the potion you drank is doing its work. Your shaft is still fully engorged, and you can definitely feel it’s a bit larger now by a couple inches. If this happened in only a couple minutes, and that you have to triple your size to win the bet, then you’re gonna need to last 20 minutes to win this.

 

When Zecora finds you, a whole hour has passed.

 

Even though you limited yourself to the parts of the forest you know, those already provided a near infinite number of hiding places. You quickly found yourself encumbered, but that wasn’t even the worst.

“Truly your desire for more growth knows no limits.” The zebra mare comments, as she circles around and pats your cock, now the size of a full-grown tree.

“You’d ask more, even with the world stuffed in my tits.”

 

You can only answer with a fevered chuckle in the dark.

You were immobilized a while ago, but already you were hidden well enough. More than the impossible size of your stallionhood, what gave you away was you own moans from the growing feeling of your shaft. The more it grew, the more sensitive it became. Simply walking then waddling around would have been enough to make you erupt long ago, but as Zecora warned you, no release was possible without her touch. The prospect of growing your partner to an impossible height gave you the willpower to not surrender to the zebra mare right away, but you’ve reached a point in size and frustration your mind is getting clouded by lust, and now you just want to get that sweet release.

 

Luckily, Zecora doesn’t plan to make you wait for too long. Her current size rivals the one of the princess of the sun, but still she has to hug and stroke the base of you cock with her whole body. Stretching her legs as far as she can, she’s about a foot short from completely reaching around your girth. Not that you needed that much. Oversexed like you were, her touch is more than enough to push you over the edge. You feel you spooge travel up through your colossal length, then cry in bliss as you shoot your load in the night. You feel like you could just pass out from the otherworldly pleasure, your mind going numb under the erotic signals coming from far too many nerve ends.

 

You don’t know how long this lasts, not for how long your body quivers from your intense climax, but as you senses comes back to you, you realize the ambient rumbling doesn’t come only from you. In the dark, Zecora’s loud moans up in the air is the surest indicator that the zebra mare is expanding rapidly. You only see clues in the dark. Shifting walls around you, booming sounds of hooves that could be larger than houses hitting the ground, and the smell of Zecora and her arousal getting increasingly thick in the air.

 

You can only wonder how big the zebra mare exactly is, but you get part of you answer as you feel a hoof grabs your towering, still hard prick. Before you realise it, your tree trunk of a cock is rammed inside an adequately giant mare cave. Even though you just came, the feeling of Zecora’s marehood brings you back to cloud nine in no time. You erupt inside her again, and again. Showered by waves of her juices and hearing her blissful cries of pleasure atop you, you feel your mind being overwhelmed by the raw sexual thrill of the giantess using your oversized penis. Forgoing preliminaries, Zecora just pumps her massive form up and down your overstimulated tower. You barely register the mare’s moans getting higher in pitch amidst the plethora of your own climaxes, but then you’re taken completely inside her, and Zecora’s behind smashes you and everything around. While she rides her own orgasm, you climax one more time too, feeling the mare’s melon-sized clit on your chest, the base of her might tits around your head, and her thick pussy lips and endless rump squishing your arms and legs.

 

Dizzied from the quick succession of sexual highs, you barely register when Zecora lifts herself from you, and that she picks you up in the air. When you come to your senses, the silhouette of the zebra mare’s head fills your whole vison under the moonlight, her smile bright even in the dim light.

She’s lying on her belly, and still her head peeks over the canopy. Well… You’re pretty sure it does, even though that last romp made a new clearing in the Everfree and that the only trees that weren’t crushed into toothpicks are bend like in the aftermath of a cyclone. Still, you estimate Zecora is about 50 feet tall now.

 

“Well played.” Zecora smiles down at you as she sees you emerge from your orgasm-fuelled stupor. “It seems I’ve grown more than three times indeed.”

“I’m sure you won’t complain I cleared the obvious need.”

“But as agreed, you may now command as you please.”

“So tell me, how shall we have fun among the trees?”

 

“I want to grow until I'm the right size for this cock!” You cockily declare to the giantess holding you. “Then, every time I make you cum, I want to grow more, cock included. I promise that before the night is out, you’ll be stretched over a shaft twice your size!”

 

However, Zecora’s smile peters out at your order.

“My… that didn’t sound very appealing to me.”

“Sorry, for that one I’m not gonna bend the knee.”

 

“Wait, really?” You say dejectedly. “Come on, I’m sure you’ll like it! And what was the point of this bet if you weren’t actually gonna listen to me?”

“Well, I confess I wanted something else from you.”

“I love seeing you small, I thought you liked it too.”

“I thought your wish would go that way to some degree.”

“But a role reversal… that just doesn’t suit me.”

 

“B-but you can’t refuse!” You call her out. “You promised you would do what I say!”

“And what shall you do? Brew your own potion maybe?” Zecora scoffs with a smugness you didn’t know her.

“Any power you have, you just owe it from me.”

“And right now, it dawns on me I’ve been spoiling you.”

“Anything you want, using me after I grew…”

“That’s not something to offer to a little colt!”

“It’s time I put an end to this tiny revolt.”

 

“That’s just a low blow. I… I didn’t expect that from you, Zecora.”

The giant zebra mare answers with a sly look. It seems this is just a game to her, and it’s not like you can even run away. Carefully placing you on the ground, Zecora starts to stroke your disproportionate shaft with a hoof of her. The giant meat bar had gone slightly flaccid, but it stands right back at attention under the giant mare’s touch, and again your mind feels on the verge of being shorted by the avalanche of pleasurable feelings.

 

“You had your chance to get a reward to enjoy.” Zecora says.

“But since you chose greed, tonight you shall be my toy.”

 

The rest of the night owes up to that simple statement. You’re used again and again by the giant zebra mare, nearly frying you brain by tide after tide of thundering orgasms. Your cock goes in all her holes, and between Zecora’s pillowy tits too. And yet you remember barely any of it. You’re handled more recklessly from here on, and no respite is let to you. At every second there was a hoof, a tongue, or a pussy to milk your seemingly infinite supply of cum. In the dark, the pleasure from your own dick controlled you, and Zecora used that to get herself a docile accessory worthy of her stature. You pass out after having spent several hours without managing to form any coherent thought in your brain, overwhelmed by an ocean of lust.

 

You wake up the next day in Zecora’s hut. Your groin is sore, and your mind feels sluggish. And somewhat, despite the countless releases you experienced yesterday, you feel rather horny right out of the bed. It is a strange, sickly feeling. It’s like a single touch of a mare could make you get off again, even though your cock returned to its original size.

 

In fact, just looking up to the zebra mare in the hut with you makes a sexual jolt run down your spine. Zecora sports the stature of a princess already, and she seems to be brewing a new potion at the moment. As she notices your open eyes, she shows you a mischievous smirk, before approaching you.

It’s strange, you feel both a slight apprehension coming from Zecora’s movements, and yet the overwheling assurance of a prowling predator.

 

“Hello there. Looks like you had a good night of sleep.” She start

“I want to talk. I want our relation to leap.”

“You know, last night was a revelation for me.”

“I loved being giant, to tower like an oak tree.”

“I loved the control I had over you, my lover.”

“As you see me, I’m forever drunk on that power.”

“While last night was more than a little different.”

“I believe that in it you still found fulfilment.”

“So today I’m asking you. Give yourself up to me.”

“Lock away your life from the past, and give me the key.”

“I’ll take care of you as my most precious belonging”

“In turn, every day you’ll get to see me growing.”

“Me getting bigger, more beautiful, and stronger.”

“To highs and heights unseen, forever and ever.”

 

 

Your thesis was submitted about a year ago. You got many good reviews and recognition from your teachers as your work was deeded a remarkable contribution in the field of botany among the Canterlot academy. Since then, you’ve left field research behind, much to the surprise of those who were now your peers. Instead, you’ve now taken it upon yourself to remain in the dusty laboratories and classrooms to teach to the newer generation of ponies in the academy.

 

However, what you had left behind was catching up to you. It started as rumours of a strange cult in Ponyville. Tales of mass depravity and submission to strange idol of pleasure at first. But soon the rumours took flesh in the form of the cultists preaching the word of the new goddess Zecora in all of Equestria. The main arguments these missionaries had to offer was a powerfully seductive appearance, twice the size of the average pony, and with assets that would put to shame even the most luscious conventional pin-ups. These ponies promised infinite pleasure to those who joined them to meet their goddess Zecora in the Everfree forest, and something in their mere presence could spark a shiver of lust even I the most disinterested soul. And ponies followed them. They returned as taller, sexier version of themselves, but otherwise still the same. Not a single of them regreted their change, and they would gladly recommend to anypony to go through the same process as they did. They would also return to the Everfree forest to perform the lustful ritual of their new faith from times to times, and sometimes returning with an even bigger, sexier body. The number of these cultists was steadily increasing everywhere int eh world.

 

From their stories, you understood that in the final stage of her brewing experiments, Zecora’s body itself now produced all the effects she could desire, growing autonomously, and potentially indefinitely. At least, rather than to outgrow the world itself, the zebra mare was willing to spread her results to some degree, but demanded total submission to ponies in return. In truth she could have allowed other ponies to reach a similar level, but it was clear she revelled in being at the very top.

 

Nights belonged to her now. If her predicators were on thing, the reality of Zecora as a goddess could be witnessed every night. The followers who visited her in the forest worshipped her in a display of sexuality that resonated miles and miles around, and the goddess mare allowed herself to grow to ludicrous heights and proportions. Her moans could be heard through all of Equestria some nights, and her shadow would for a minute blot of the light of the full moon. Some days you would just wake up in the middle of the night, your shaft engorged, as the memory of the giant zebra mare’s scent was fleeting on the whole city.

 

At some point Zecora had offered you her deal. With what you see know, it’s hard to say if you’d have ended up anything more than one follower among many others. The fact is that you refused. There’s something about the story of the wolf and the dog in here somewhere. The price was your freedom, but in exchange you would have had a prime seat to witness Zecora master the full extent of the power of the Everfree forest. Even if it would have been only up to her whims, she could have gifted you with pleasures out of this world. You would have participated in nights after night of orgy in the honour of the mistress of the forest. You would have braided her yards of mane, worshipped her hills of flanks, wrestled her nipples for torrents of milk, explored a marehood worthy of the castle of Canterlot…

 

You blink as you realize you’ve been spacing out. You better stop thinking about this. After all this time, a part of you still wants to change your mind…

 

THE END
