It begins

"So..what exactly do you need me for, again?" Soarin asked as his hooves touched the soft grass outside the Sweet Apple Acres barn, glancing to his side to see Rainbow Dash landing beside him. "You never actually explained that part to me."

"Uh...heh..." Rainbow Dash blushed and grinned nervously as she landed, shaking her head a bit. "It all started as a harmless prank, honest! Me and Pinkie didn't mean anything by it, but, uh..." she trailed off again just as the barn door cracked open, a familiar purple princess poking her head out and grinning wide.

"Ah, you're finally here!" she called out, eagerly trotting up to the two pegasi, eagerly wrapping a wing around Soarin's back and gently tugging at him. "Quickly, we don't want to waste any more time!"

"Egh, what's the deal with you mares today?" Soarin groaned as he was pulled, trotting alongside the alicorn towards the barn. "Can someone explain to me what is going on here, and why I'm needed?"

"Well, you see, of all the currently available stallions in the immediate region of Equestria, I was able to determine that you were the best fit for our current needs!" Twilight spouted off rather quickly, opening the barn door back up with her magic again while Soarin raised an eyebrow, which soon turned into a flat-stare.

"...This isn't another one of those days where I'm being herded off to have sex with some needy mare, is it?" he stopped in front of the door, while Twilight smiled and blushed back at him. "Because it would be the third time this month."

"Ahh...maybe?" Twilight giggled nervously, stepping into the barn while Soarin sighed and shook his head, reluctantly following after her.

"It might be, but this time it's different!" Rainbow Dash chimed in, coming up behind the stallion and gently pushing him from behind, after closing the barn door behind her.

"I'm getting tired of this, you two." Soarin groaned, rolling his eyes as he followed Twilight further into the barn, glancing past a bunch of stalls, which were normally used for milking cows, but all seemed to be empty now, except for one, which was occupied by a large white tank. "I'm a Wonderbolt, you know? I've got places to be, practices to do, and other impor..." his sentence was cut off as he spotted something jutting out on the other side of the tank now, immediately piquing his interest.

"Is that..." he stepped up closer to the tank and quickly looked around the other side of it, pausing for a moment before both of his wings immediately flared up and stood stiff. "Applejack!?" was all that escaped his mouth before his jaw dropped, his eyes rapidly darting around to fully gaze over the seemingly magnificent sight before him.

In the stall next to the tank was the mare in question, though sticking out between her front legs was the most massive stallionhood Soarin had ever laid eyes upon, its length easily longer than the mare it was attached to, with an astounding girth to match, easily the same thickness as the mare it was attached to! Encasing the first half of the shaft up to the medial ring was what appeared to be a plastic tubing of some sort with a rubber hose attached to the end; the stallion watching in awe as an almost constant stream of thick white seed flowed from the flared tip of the huge marecock, being pulled up into the rubber tube, which looped over the top of the stall and into the tank. The cylinder seemed to be vibrating around the monstrous cock as well, causing a slightly-audible humming noise.

"This is what we needed your help with, Soarin." Twilight came up beside the stallion, who was still very much in awe, his wings gently twitching while at the same time, his own member was already pushing forth from his sheath and hardening between his legs. "We needed a stallion to help, uh...milk Applejack, and pegasi are well known for their stamina."

"H-how..." Soarin finally managed to speak, turning his head towards Twilight. "What?”

"You see," Twilight continued, looking towards Applejack again, "Applejack's growth was caused by a contact with Poison Joke, and quite a lot of it." she glared at Rainbow Dash, who grinned sheepishly and looked away. "As you can see, we've been trying to purge the built-up magic within her, but to no avail. No matter what we've tried, we simply cannot get it out of her faster than it's being produced."

"I see..." Soarin gulped softly as he stepped up closer to the lightly-bound mare, who was groaning and panting quite heavily, somewhat lost in a haze of intense arousal; that massive shaft throbbing quite powerfully below her body. Now fighting a heavy blush of his own, Soarin turned back to the other two mares, "But, why specifically me?"

At this question, Twilight couldn’t help but turn a bit red as well. "Um, Rainbow told me that you are, uh...into this kind of thing..."

Rainbow Dash giggled as she stepped up on the other side of the stallion, draping a foreleg over his shoulder. "You really need to hide your porn magazines in a better place, Soarin." she teased, finally making the stallion blush quite deeply. "I didn't even know they made magazines for this kinda stuff."

At that moment, Applejack groaned and leaned her head back as another orgasm hit her; the stallion watching as her hefty balls lifted up, before a fresh stream of cum flowed into the tubing, adding to what was already in the tank. For a good ten seconds, the tube was solid white with steamy futa seed, before the hyperphallic mare sighed and relaxed, the giant orbs between her legs slowly lowering again, though they were only noticeably smaller than they were moments ago.

"Well, um...I'd be happy to uh, milk her." Soarin turned his gaze back towards the other two mares, though he raised an eyebrow as they both seemed to have left, leaving him alone with the bound mare. "Oh...guess it's just you and me then, Applejack."

“Ngh...m-mighty fine to meet ya and all, but...ngh...I’ve got a huge problem here that needs fixin’!” Applejack groaned as she looked up at the stallion in front of her with quite a needy look in her eyes. “So if, oooh...ya don’t mind…”

“Of course…” Soarin nodded eagerly; his own erection fully hard as well at this point, throbbing with need between his legs. As he moved behind her, he gazed down at her plump rear, raising an eyebrow as he saw a puffy anus and a massive pair of balls, but no female parts in sight. "Damn...they're still so big, even after she pumped out so much." Soarin gulped softly as he sat down behind the futa mare, bringing his front hooves up and beginning to stroke over the heavy orbs, only eliciting more pleased groans from the mare they were attached to. "There must be many gallons in each one..." he bit his lip gently as he stroked and rubbed over the huge balls, his member sticking straight out from between his legs now and throbbing quite a bit from his ever-increasing arousal.

Leaning in further now, he pressed his snout to Applejack's balls, lightly nuzzling over them as he inhaled their thick scent, definitely matching that of a stallion's. With a pleased groan, his tongue slipped forth and began to slurp over the smooth sack, tasting the mixture of seed and a light amount of sweat from the smooth orbs. With the scent and flavors overwhelming his senses, his arousal shot through the roof; the erect between his legs throbbing even more, almost painfully hard now.

"Mmngh...ahh..." Applejack lightly whined and shuffled her legs a bit from the teasing pleasure her balls were receiving, causing the flow of precum to noticeably increase as her gargantuan member throbbed with need. Soarin continued to worship the mare's massive nuts a little longer before finally pulling back and letting out a blissful sigh, his gaze meeting the mare's plump rear once more as he sat up.

Without even thinking about it, both of his front hooves came up and lightly pressed to the soft rump, rubbing and massaging over it while his eyes fixated on the puckered ponut between the two cheeks. With a heavy blush of his own, he leaned in and stuck his tongue out once more, beginning to lightly slurp over the mare's rear entrance, feeling it lightly clench as the futa mare gasped in surprise.

"Mmnh!" Applejack leaned her head back and shuddered at the feeling of the warm tongue slurping between her plump buttcheeks, providing a slightly different feeling of pleasure than what the vibrating cylinder or the teasing to her balls gave her. "Aahh..s...Soarin..." she groaned, eagerly trying to press back against the stallion with what little movement space she had.

Squishing the mare's soft rump a little more firmly, Soarin continued to drag his tongue over the soft ponut, repeatedly slurping and prodding it with his tongue, enjoying the pleased whines and cries it was evoking from the lustful mare. All too eager for some pleasure of his own, he shifted his back legs a bit, positioning his stallionhood until he felt it rubbing against the mare's giant balls. With that, he gently thrust his hips forward, sliding his member between the two orbs, groaning as he felt his length being lightly squeezed between them, rubbing along the smooth, warm sack.

Almost immediately, he began to lightly buck his hips back and forth, humping between the giant balls as if they were a pair of oversized udders; pleased groans escaping his lips as his tongue continued to worship Applejack's soft rear entrance. Of course, the firm thrusting against her balls only made her groan louder as even more precum was coaxed forth, splattering into the tube around her shaft.

"Aahh...mmnhh...!" Soarin continued to slurp and lap over the clenching ponut a little more before pulling his head back, panting quite a bit now from the exertion of his thrusts. His own member was spurting loads of precum already, smearing between the mare's balls and only adding to their warmth; his thrusts accelerating a bit as his arousal continued to skyrocket. "Applejack...ngh...your balls feel...amazing!" he groaned, finding a bit odd that he would ever be saying something like that, but nonetheless, he leaned forward a bit and continued to hump between the huge orbs, already feeling an orgasm creeping up on him from how horny we was getting.

Of course, the mare reached her next climax first, lightly shuddering and pulling against the bindings a bit as she whined and moaned, feeling the huge pressure between her legs starting to release for a second time. Once more, her massive balls clenched and lifted up, managing to squeeze Soarin's cock between them, making them feel much more snug around his shaft as they churned and pumped another load into the plastic tube.

With this tight squeeze, Soarin gasped and let out a pleased grunt, immediately bucking his hips even harder as he felt his own orgasm coming on; his flared wings lightly fluttering behind him while he squeezed the mare's flanks even tighter, really thrusting his member against the soft orbs. "Ngh, Applejack...ah!" he leaned his head back and groaned out loudly as he began to cum with her, pushing his crotch against her rump as he felt the rush of seed pumping from his own balls and gushing from the flared tip of his cock, a good gush of it splattering between the mare's giant orbs before his cocktip pushed out past them, splashing the underside of Applejack's shaft a little as he began to make quite a puddle of seed beneath her.

After a few sizable gushes, the pegasus finally relaxed, slouching forward a bit as his orgasm came to an end; feeling the mare's balls relaxing as well, unclenching and lowering back down to their original position. Opening his eyes again, he let out a deep sigh, grinning down at his lustful partner. "Mmnh, did that help any, AJ?" he asked, gently rubbing his hooves against the two groups of apples on the mare's flanks, seeing the mare's head leaning down a bit as she panted with him.

"Nnhh...Soarin...th-that felt...ah...wonderful..." she softly groaned between her panting, while the stallion slowly lowered himself back down, leaning his head down to glance between the mare's legs again.

"Heh, glad to...mnh, hear it." Soarin grinned confidently as he gazed upon the futa mare's balls, still quite huge, but noticeably smaller than before. "Looks like that worked a bit...though I think I'll need to milk you quite a bit more, before you're empty." he stood back up again, his gaze meeting with the mare's puffy ponut once more, still slick and lightly-glistening with his saliva. Despite just cumming moments ago, this lovely sight greatly helped rekindle the pegasus' lust; his member lightly twitching between his legs again.

"Well...time for round two, I guess." he teased after a couple more moments of resting, getting back to his feet and lifting his front legs, grasping the mare's flanks once more. Pulling himself closer, he pressed the flared tip of his shaft against that snug rear entrance, lightly prodding and grinding against it. "If this doesn't drain you...mmnh...nothing will." he added with a playful smirk, causing the futa mare to blush deeply once more; her own erection still throbbing hard as ever.

Wasting no more time, the pegasus pushed forward, firmly penetrating the snug rear in front of him and grunting blissfully once more, feeling the snug squeeze around his twitching member as it pushed inside. "Ahh...ngh...s-so tight..." he grunted, while Applejack gasped and moaned with yet another surge of pleasure coursing through her body, her anal muscles instinctively clenching around Soarin's length as it pushed so firmly inside her.

"Soarin...nggh!" Applejack grunted again, leaning her head back and whining once more from the mix of pain and pleasure the firm penetration brought her; lightly squirming and shuddering against the stallion as he continued to push and push, sliding his throbbing member deeper inside her with each moment. All the while, her own flow of precum continued without a hitch, steadily filling the tank little by little.

Unbeknownst to the two ponies though, the tank in the other stall was nearing its limit; having filled to at least 90% capacity by the end of the mare's previous orgasm. With the loads of precum continuing to fill it up, the metal began to lightly creak and groan as the tank reached capacity...surely the next flow of seed would be more than enough to overflow it.

Just as his medial ring sunk inside the snug rear, Soarin smirked and gave a firm thrust, immediately shoving several more inches of his length inside; only eliciting a louder moan from the futa mare. "Mmngh...you feel so good, Applejack!" he grunted, pressing deeper still while his own warm pre continued to flow, helping to lube the snug anal passage. As he pushed deeper, he could feel a strange tingling starting to course through his stallionhood, though it only fueled his lust, prompting him to start his humping.

"You're squeezing my cock...ngh...so tightly!" the lustful pegasus groaned, panting softly now as his hips began to steadily buck, sliding his member back and forth deep within Applejack's snug rear; his hooves sliding up from her rear now and to the sides of her body as he began to lean forward, positioning himself better for further humping. His spread wings began to lightly flutter as well, helping him put a little more power behind each of his thrusts; hearing the pleased moans and groans from the mare in front of him each time his crotch smacked against her soft rear.

"Oh yeah...Soarin...ah!" Applejack continued to groan and pant each time the stallion thrust into her snug rear, feeling her body start to lightly sway back and forth from the force of Soarin's thrusting, especially with him leaning his body weight against her now. Amidst her lustful haze, she could also feel a tingling feeling deep within her, as well as the feeling of the stallionhood thrusting even deeper within her, noticeably deeper than before.

At the same time, Soarin grunted more lustfully, having to put a little more strength into each of his thrusts, feeling the mare's snug rear seemingly squeezing even tighter around his throbbing cock. "Ooogh...yeah...squeeze my cock tighter...Applejack!" he grunted, though it wasn't Applejack's rear tightening, instead...his own length seemed to be swelling!

The same poison joke that had infected the mare now seemed to be having quite an effect on the stallion humping her; spreading to his member and causing it to slowly grow even longer and thicker, making the futa mare's insides feel like they were squeezing tighter with each passing moment. It wasn't until at least a minute later that the stallion finally began to notice this, one of his hooves stroking along the mare's belly and feeling a strange bulging that seemed to be happening in time with his thrusts.

"Mmngh...wh-what is that?" he groaned, momentarily stopping his thrusts and sliding his hips back, only to notice that even with his hips pulled back, his medial ring was still inside the mare! "Ah, what the...my cock is growing?" he gasped and looked down, seeing that his dick was almost twice as thick as normal, veins bulging along the length as it throbbed with lust.

The arousing sight only seemed to further invigorate the pegasus; his hips thrusting forward again only a moment later, burying his swelling cock within Applejack's snug rear and resuming his eager pounding, his panting becoming quite heavy now as the concentrated lust between his legs continued to intensify. The strange bulging that he previously felt was now much larger from all of his growth; bulging the mare's belly outward in its shape each time he bucked forward.

"Ohhh...f-fuck...yeah...!" he groaned out loudly, flapping his wings quite a bit now to help his rough thrusting, feeling his balls start to really sway back and forth, also seeming to swell to keep up with the size of his stallionhood. Just as with the futa mare, loads of his precum gushed forth, soaking the snug insides while they continued to squeeze around his growing length. "This is...nggh...incredible...Applejack!"

Of course, with that huge length growing thicker and pushing deeper into her with every thrust, Applejack's lustful moans became much deeper; feeling her body rocking back and forth with the stallion's thrusts while her own endowment continued to throb wildly and spurt off loads of pre, inching the tank closer and closer to its limits. "Aaaahh...nnh...!" she leaned her head back and panted with lust, her insides clenching repeatedly around Soarin's length, eager for it to push even deeper inside her.

With the Poison Joke still affecting him, the mare would certainly get her wish; Soarin's grunts becoming a bit louder between his heavy panting as he kept up his rough thrusts, leaning further forward with every thrust until his chest was up against the mare's back. Both hooves now held onto the sides of Applejack's enormous shaft, lightly squeezing it and feeling it throb powerfully as a third orgasm rapidly approached. "Nnggh...hhaahhh...I'm going to...milk you dry...!" he grunted amidst his own lustful haze, his mind set on both his own pleasure, as well as bringing as much pleasure to the lovely mare as he could.

By now, his stallionhood had swollen to nearly twice its original size, obscenely bulging the mare's belly each time he thrust deep inside her, while between his legs, a pair of quite huge balls swung back and forth, slapping and bumping against Applejack's with each firm buck of his hips. His wings were really flapping as well, helping to push and pull his lower body back and forth with all of its added weight; his panting becoming deeper still from all of the physical exertion. "Cum for me...ngh...Applejack!" he groaned, firmly rubbing his hooves along the sides of that giant futa cock, feeling it throbbing harder at a quicker pace and knowing the mare was nearing her climax. Of course, with all of the tight squeezing her rear was doing, he wasn't too far off either; gushing loads of pre inside her from his ever-swelling orbs.

Just as the stallion wished, Applejack reached her third orgasm just moments later, letting out a sharp moan and leaning her head back while her own hips bucked as much as they could, helping to pull the still-swelling stallionhood deeper inside her; the snug inner walls clamping around it like a vice as her balls lifted up once more, forcing out what would easily be their biggest load yet. Almost immediately huge gushes of the mare's thick essence burst from the tip of her shaft, quickly beginning to fill up the plastic tube, as the hose proved to be too small to suck up all of the seed, at the rate it was coming out. In just a few moments, the plastic tube and hose had become completely solid white, all while the mare continued to pant and groan out loudly, her eyes rolling back from the sheer bliss coursing through her body.

Of course, with the very snug squeeze around his now giant member, Soarin grunted and tightly shut his eyes, feeling his own orgasm coming on after just a few more thrusts. "Nngh...fffuuuuggghh...!!" he groaned before slamming his hips against the mare's rump one last time, obscenely bulging her belly outwards with his oversized length as it began to erupt as well, pumping out a torrent of seed deep within the futa mare. Immediately her belly began to round out and swell, bloating further and further with each throb of the stallionhood inside her; the steamy filling only intensifying the pleasure of her powerful climax.

The two ponies were far too lost in their respective orgasms to notice the tank beside them creaking and groaning even louder than before; the bolts all along the top of it coming loose rather quickly as the thin metal began to bend and give out from the pressure of the gallons and gallons being forced inside it. Being able to hold no longer, the top of it finally burst off, erupting like a volcano of steamy futa seed, inevitably showering all over the stalls on either side of it and soaking both of the horny lovers in the process.

"Aahh...nnghh...!" Applejack groaned out loudly, her eyes closing tightly as she felt her own steamy cum splashing against her face and back, while at the same time, further surges of warmth filled her insides, her belly bloating quite large and round, pressing her monstrous shaft against the floor. With her eyes closed though, she began to feel quite faint; wobbling a bit and slouching as the pegasus on top of her seemed to become heavier as well, pressing more firmly against her back. The last thing she remembered feeling was the tube around her cock starting to loosen and slide forward before she slipped into unconsciousness.

The earth mare remained out cold for roughly an hour before finally opening her eyes again, lightly groaning with fatigue while feeling returned to the rest of her body. Immediately she felt the right side of her body soaked with something warm and thick; quickly realizing that she was laying in a rather large puddle of semen, with Soarin laying down behind her, still cuddled against her back. Looking down between her legs though, she sighed in relief, not seeing any male parts except Soarin’s, now flaccid and back to its normal size.

Her slight movements roused the pegasus from his sleep as well, a soft sigh escaping his lips as he leaned his head back a bit, shuddering softly as he too felt the warm wet feeling along the right side of his body; the thick seed matting his coat down quite a bit. “Ngh...Applejack?” he softly spoke, gently moving the hoof that was draped over her body, while his other front leg felt numb from being pinned underneath the mare. “Are you alright…?”

“I think so, hon.” Applejack groaned lightly as she leaned over and slowly pulled herself up to her hooves, her body feeling quite sore from the rough pounding she had received. “Looks like that nasty plant finally wore off.” she looked down between her legs again and smiled softly. “Heh...never been so glad to see that before.”

With a bit of a blush and a smile of his own, Soarin got to his hooves as well, shuddering softly from the feeling of the room-temperature semen oozing off the side of his body. “Egh...well, uh...glad I could be of assistance.” he grinned over towards the earth mare, lightly fluttering his wings before they folded against his back again. “It was really...enjoyable.”

“Tell ya the truth, it wasn’t all bad for me either.” Applejack blushed now as well, lightly brushing one of her front hooves along the ground as she smiled back at the pegasus. “Just kinda...too much of a good thing, y’know?” she giggled softly, while Soarin gulped softly, rather aroused by the mare’s reply.

“You mean...you LIKED that?” Soarin raised an eyebrow, not exactly opposing the mare’s admittance to being interested in his biggest fetish, but still surprised by her answer. “You seemed really horny, but you referred to it as a problem that needed fixing.”

“Well yeah, it was pretty upsettin’ having a penis so big that I couldn’t even move, and being so horny that I couldn’t think straight for more than a couple seconds.” Applejack giggled, moving beside the stallion again and gently brushing against him. “But...if it were a reasonably large size...I don’t think it would be half bad.” she added with a bit of a grin, while Soarin’s wings fanned out to the thought of Applejack having even a semi-permanent hyper-sized futa cock.

“So, uh…” Soarin gulped softly again, his cheeks flushed quite red once more, “If you just happened to trot through some Poison Joke again…”

“You’d be the first pony I’d come lookin’ for.” Applejack smirked playfully, gently nuzzling the stallion’s blushing cheek and giving it a soft slurp, only making his wings fan out even harder. “And I know just where a bunch of Poison Joke grows.” she teased, giving the stallion’s cheek another soft nuzzle before stepping forward and grinning back at him. “How’s next weekend sound, sugarcube?”

With an eager grin, Soarin nodded rather quickly, his wings lightly twitching while already, his stallionhood began to stiffen up again from all of the naughty thoughts flooding his mind. “Y-yeah, Applejack...that sounds great!”

“Heh, good. As for now though...I reckon we should wash up before Big Macintosh comes back from the fields.” Applejack giggled softly again, spotting the pegasus’ stiffening shaft and smirking a bit. “Don’t be gettin’ any ideas while I’m showering off, either.” she teased, trotting off towards the shower stall at the other end of the barn, Soarin following closely behind her.

“Fascinating.” A voice came from towards the other end of the barn; the door cracked open just a bit to reveal Twilight peeking through it, grinning a bit. “The effects of Poison Joke on earth ponies seems to still be temporary, despite being amplified so much. We’ll have to do some further, ngh...experi..ah!” she grunted and closed her eyes, unable to finish her sentence from a sudden surge of pleasure.

Beneath her, Rainbow Dash shuddered and groaned around a rather large stallionhood protruding out from between Twilight’s legs, her own eyes closed tight while loads of seed splashed out around her lips; her neck bulging repeatedly as she struggled to gulp it all down.

“Ahh...mm...still quite potent for Alicorns, at least…” Twilight sighed happily, looking down at the pegasus beneath her with a rather pleased grin on her face, her wings lightly twitching as she listened to the loud gulping and slurping from below. “But yes...we shall experiment more...ah...much more!”

THE END
