Also, I have no idea what the vet pony's name really is. I'm just going with the name for her that I was given.

Animal Antics

“Don’t worry Spike, the vet should be able to fix you up.” Twilight assured the greed-grown dragon as she pushed open the front door to the veterinary building, leading the purple dragon inside. After a short wait, the secretary called for Twilight, bringing her into the main checkup room. Once inside, Spike hopped up onto the large table and sat on it, his legs hanging over the edge.

"The doctor will be with you in a moment." the secretary answered sweetly before leaving the room, Twilight going over to the chair near the table and sitting down in it as well. "Hopefully the vet will know something that can cure this." she thought, watching as Spike eagerly glanced around the room at all the things he could possibly steal, his tail wagging anxiously.

“Alrighty, what have we here...” came the voice of a yellow-coated, cyan-maned mare, carrying a clipboard in one hoof as she walked into the room. “We have a....dragon?” she thought out loud, glancing up at the grown dragon sitting on the table in front of her, rather shocked at such a sight. Almost immediately, she felt a tingling between her legs, her arousal sparking already just from the sight of a pony-sized dragon. “Oh my...a dragon.” she repeated as her cheeks tinted red ever so slightly.

As with any veterinarian, she loved animals of course, but this veterinarian loved animals...a lot more than most, putting it simply. Whether it be dogs, cats, or whatever pet came to see her, this mare has had more animals in her than the Canterlot Zoo. That’s not to say she didn’t care for them as well. After all, she was a skilled veterinarian, and the animals loved her additional “treatments” with each checkup just as much as she did, so she didn't really see a problem with what she was doing.

But this time was something special. She had never been brought a dragon before, let alone one that wasn’t fifty feet tall. Her medical training didn’t include much of anything on dragons, but her quirky interest in animals led her to study them on her own, reading much about their inner workings and bodily functions. Finally getting to meet one in person was like a dream come true for her.

“Yes, Ms. Mane Goodall?” Twilight started, smiling a bit from where she was sitting, in the chair next to Spike. “I was wondering if you could help my dragon, Spike, here. He appears to have had a strange growth spurt, and I think it might be caused by his natural dragon greed. At least, that’s what the book said.” she explained, slapping Spike’s hand away from the jar he was reaching for.

“Mm...I see...” the yellow mare nodded softly, putting a hoof to her chin as she glanced up and down Spike’s body, rather intrigued by the fact that he was apparently grown from a smaller size. “I’ll need to...perform some rather advanced tests before I can diagnose him. I’m not sure how long it will take.” she lied, glancing over towards Twilight now. “Shouldn’t be too long, though.”

“Oh, thank goodness. What are you going to do first, then?” Twilight asked after a relieved sigh, getting up from her chair and swatting Spike’s hand away again, glaring a bit at him.

“Well, first I want to make sure Spike is comfortable. I advise you to go and wait in the waiting room...I find that pets tend to calm down more easily with their owner out of their thoughts.” she lied again, feeling another eager tingle between her legs, her nether lips already moistening a bit from all the naughty thoughts circulating in her head.

Twilight blinked a bit, raising an eyebrow, but remembered that the vet probably knew better than she did about pet care. “Um...if you insist. I’ll be right outside if you need me.” she replied, before walking towards the door, glancing back at Spike one last time before exiting. Once the purple unicorn was gone, Goodall smiled wide in excitement, happily trotting over to the door and latching the deadbolt on it, making sure that nobody would be able to interrupt her.

“So...your owner says that greed makes you grow bigger, hm?” she asked in a rather sultry tone as she approached Spike again, pulling her shirt up over her head and tossing it aside, leaving her body bare. Spike raised an eyebrow in confusion to the mare’s advances, though his eyes suddenly widened a bit as her aroused scent reached his nostrils. He watched as she climbed up onto the table with him, before turning away and leaning her upper body down, raising her rump up nice and high, presenting her rather plump rear to him.

“Well? See anything you want, my dear?” the mare teased with a soft giggle, wiggling her rump for the dragon, the close proximity of her moistening cunny only serving to help fill the dragon’s nostrils with her scent.

“Spike....want!” Spike growled, reaching over and grasping the mare’s flanks, giving them firm squeezes, only making her moan cutely as she was handled so roughly, her cheeks blushing a bit more in arousal.

“Ahh...oh, such a naughty little boy...” she moaned happily, feeling those smooth claws groping and squeezing all over her rump, a touch unlike any other she had felt before. “Mmnh, I take it you like that, Spike deary?” she teased, glancing back at the dragon and seeing his twin members pushing out of the slit on his crotch, only causing another strong tingle between her legs as her arousal grew.

That was the one thing that intrigued her the most about dragons and other lizards: Their hemipenises. After all, two is better than one, right? Especially when those two penises were just the right size for her. “I’ll take that as a yes...” Goodall added, sighing blissfully as she turned around again, pushing Spike’s claws off of her rump. Glancing down between the dragon’s legs, she licked her lips gently, seeing both of his members sticking straight upward from his crotch and twitching softly, both of them measuring in at roughly sixteen inches.

“Mm, perfect...” she thought out loud, before smiling up at Spike. “Just lay down and relax, deary, and I’ll make you feel all better.” she spoke in a sweet, yet sultry tone, before gently pressing her hoof against Spike’s chest and laying him back on the table, sitting between his legs. Spike looked down as the mare reached for his twin members, grasping both of them and beginning to stroke them up and down, making him growl in pleasure.

“Ooh...you’re awfully hard, Spike...you must really like your veterinarian.” Goodall teased with a soft giggle, hearing the dragon’s pleased growls as she stroked his two prides, feeling them throb and twitch against her soft hooves. A bit of precum smearing onto her right hoof after a bit of stroking, making her grin lightly and bring that hoof up to her mouth, lapping it gently to taste a sample of the dragon’s semen. “Mmmnh...rich, yet...somewhat sweet.” she thought out loud, licking her lips gently.

Eager to taste more of the dragon’s seed, she continued stroking Spike’s members steadily as she leaned down, inhaling the thick, musky scent emanating from the two throbbing poles, only making her sigh blissfully as her marehood tingled again, already very wet with arousal. Opening her mouth slowly, she slid her tongue out and began to slurp the dragon’s left member while stroking the right, tasting his warm seed with each slurp, while the dragon growled happily, snorting a couple clouds of black smoke from his nostrils as the pleasure grew within him.

“Mmmm....so delicious...” the lusty mare thought as she kept slurping Spike’s throbbing shaft, soon opening her mouth and engulfing the first few inches of it, starting to lightly suckle on it and slurp her tongue through the slit, lapping up the droplets of precum as they oozed out, getting even more of that rich, sweet flavor. “I must have more...!” she thought, sliding her other hoof down lower, stroking over the scaly balls that were hanging below, feeling their weight and size and estimating just how much the dragon would be able to put out.

As Spike growled eagerly, he reached down and instinctively placed a claw on the mare’s head, gently holding onto her it as it bobbed up and down slowly, suckling on his member, while the soft hoof kept stroking his other shaft up and down, both of them oozing loads of precum from the wonderful pleasure the mare was providing him. “Nngh...Spike...feel....funny...” he grunted as his orgasm drew ever closer with each passing moment, feeling a pressure building up in his groin as his cocks throbbed harder.

Goodall could feel his members throbbing harder in her mouth and against her hoof, somewhat surprised that his orgasm was approaching so quickly. "Mmnh, he must be really enjoying this..." she thought, continuing to stroke the dragon's meat quickly while bobbing her head up and down on the other, sliding and swirling her tongue all along the surface, feeling it throb harder in her mouth and gush loads of precum; the mare's juices dripping lightly onto the table below her from her own arousal, eagerly awaiting the dragon's orgasm to get a good taste of his semen.

And enjoying it, Spike was. His tongue lolled out of the side of his mouth a bit as he panted and growled happily, still gently holding onto the mare’s head as it bobbed up and down more quickly, while her lips pursed tighter around his twitching shaft, trying to milk it for as much precum as she could. Being a curious young dragon, Spike had pleasured himself a bit in the past, but it hadn’t felt nearly as good as what this mare was doing to him.

Hearing the dragon snort another cloud of black smoke, Goodall opened one eye to glance up at him, seeing the blissful expression on his face and grinning mentally, glad to know that she was pleasing her patient well. She kept up her work though, quickly stroking her hoof up and down the length of one cock while bobbing her head nice and fast on the other, sucking roughly half of it while her tongue swirled all along the length, only teasing the dragon with more pleasure as she suckled on the throbbing meat. “Mmnh...come, my little dragon...let your vet have a taste...”

With both of his dragonhoods being pleasured though, Goodall's wish was granted rather quickly. Only a few short moments later, Spike growled blissfully, snorting more black smoke from his nostrils as he grasped the mare's head, bucking his hips instinctively as his members both began to throb wildly. "Spike..nnggh...cumming!!" he grunted as the twin cocks began to erupt, flooding the vet pony's mouth with a river of steaming-hot seed, while his other member gushed it all over her face and mane, splattering her with strands of the sticky white fluid.

"Mmmpmhh!" the lusty mare groaned, her eyes widening in surprise to the sudden surge of dragon cum filling her mouth, trying not to waste a drop of it as she gulped powerfully, just barely swallowing it as fast as it was coming out. The rich, sweet flavor she tasted from his precum now seemed like nothing in comparison to the taste of the dragon's full load; filling her mouth completely multiple times, allowing her to fully savor the magnificent taste.

The few moments that Spike's orgasm persisted seemed like minutes to the mare, her mind lost in the euphoric taste that covered her tongue and painted the inside of her mouth; finally pulling her head back once the flow came to a stop, letting out a very pleased groan as her tongue searched around inside her mouth for any traces of the dragon's seed. "Ooh, Spike darling...such delicious semen..." the mare spoke softly, blushing lightly as she smiled up at him, still slowly stroking his other member with her soft hoof, feeling it twitch lightly after Spike's orgasm.

"And you've made such a mess of your veterinarian..." she added with a soft giggle, feeling the dragon's seed all over her face and mane, rubbing some of it off of her cheek and lapping it off her hoof, while Spike grinned in return, strangely pleased by the sight of the cum-soaked mare in front of him.

Despite his orgasm though, both of his dragonhoods were still quite stiff, standing at attention in front of the mare and lightly throbbing against her slowly-stroking hoof, still eager for more "treatment" from the mare. Noticing this, Goodall grinned lustfully while her nether lips quivered in delight; her mind flooding with thoughts of those two thick members stuffing her deep and hard.

"Mm...still nice and hard, my hunky little dragon?" the mare teased with a sultry tone again, grinning up at Spike as she kept slowly stroking and teasing his twin members, hearing low growls coming from the purple dragon as he nodded softly, sitting up again in front of her. "Hehe...time for my favorite way of taking your temperature, then." she added with a soft giggle, before turning around again and raising her rump up high like she did before, wiggling it back and forth a bit.

Seeing the mare’s lovely rump again only made the dragon growl lustfully, his twin shafts twitching more as he reached for the yellow flanks and squeezed them firmly, making the mare moan cutely again. “Spike...rrh...want!" he growled as he knelt behind the mare, pressing his crotch firmly against her rump and grinding his throbbing members against it, smearing a bit of precum over the mare’s orifices.

“Oooh...such a horny dragon...” Goodall moaned seductively, her cheeks flushing red as she felt those throbbing members rubbing and grinding against her, feeling each twitch and throb they gave as the warm precum smeared against her, only helping to lube her up a bit. “Go on, Spike dear...let your vet take your temperat-ahh!” she gasped as the dragon suddenly penetrated her without warning, roughly shoving his cocks into both of her tight holes, causing the mare to groan out blissfully.

“Rrgh...!!” Spike only growled louder from the pleasure, his hips already starting to buck quickly as he worked to push his cocks deeper inside the mare, squeezing her flanks harder and gritting his teeth gently as the two holes squeezed tightly around his twin cocks. The double-penetration was providing a wonderful mix of pain and pleasure for the mare however, making her pant and moan blissfully, gripping the edge of the table firmly to steady herself from the dragon’s firm pushes.

“Ahh...nnhh...s-slow down, Spike darling...!” she moaned in lust, finally feeling some pleasure for herself after waiting so long; her pussy squeezing nicely around Spike’s thrusting shaft while her backdoor squeezed even tighter, making it a bit tough for Spike to thrust into her. As much as she wanted the dragon to just fuck her brains out, she also wanted to savor this experience, as it’s not every day that one gets fucked by a dragon. Working her muscles a bit, she squeezed herself even tighter around Spike’s shafts, making him growl blissfully but also forcing him to slow down a bit, finding it hard to thrust into such tightness.

“Rrrgh...rrrh...!” Spike could only growl in bliss from the squeezing around his twin members, his thrusts slowing down a bit as a result, though he kept trying to thrust hard, squeezing the mare’s flanks a little tighter and snorting another cloud of smoke. In the midst of his slow thrusts though, he felt his belly rumble, having not really eaten much except for the sapphire cupcake he had earlier, leaving him somewhat hungry. Luckily, only a couple feet away on the counter was a jar of dog treats; the dragon licking his lips as he spotted them.

“Mmnh...much better...ahh...my horny little dragon...” Goodall groaned happily as the dragon’s thrusts became less erratic, closing her eyes and enjoying the feeling of the two cocks lodged deep inside her, grinning a bit to herself. “Hehe...mm...seems your temperature is just fine.” she teased with a soft giggle, before she felt a few crumbs fall onto her back, her eyes opening again as she raised an eyebrow in confusion.

Glancing back at the dragon, she smiled and giggled softly again as she saw him stuffing his face with the dog treats, still holding her flank with one claw and thrusting steadily. “Ahh...hehe...hungry, my big dragon?” she teased, poking her tongue out cutely as she watched him eat and thrust at the same time, enjoying the lighter pleasure of his slower thrusts. “Oh, that’s right, I still have to diagnose you, don’t I...” she thought; the short break having reminded her of the reason why the dragon was brought here in the first place.

“Mm, no problem then...” she added with a grin as Spike completely finished the jar of treats, looking into the empty jar and licking his lips, before tossing it over onto the chair near the table. Goodall meanwhile pulled forward, sliding the dragon’s members out of her tight orifices, before turning over onto her back and laying in front of him, spreading her legs nicely. “Hehe...go ahead now, Spike...keep pounding your doctor.” she teased with a wink; Spike smirking down at her as he grasped her spread legs and pushed his hips forward, penetrating both of her entrances again and growling happily, sliding in much easier this time due to all the lubrication that his precum provided.

Panting and moaning softly in pleasure, the vet mare reached over to the counter and grabbed her stethoscope, struggling a bit to put it on due to the dragon’s thrusting bumping her body back and forth, but managing to fit the two little rubber earpieces into her ears. Bringing the other end of the tool up, she pressed it against Spike’s chest, listening to the dragon’s heart thundering in his chest as he kept bucking her nice and hard.

“Th-thmp, Th-thmp, Th-thmp, Th-thmp Th-thmp...”

That big dragon heart thumped quickly, pumping lots of blood to the twin cocks within the mare, the sound of it beating loudly in her ears relaxing her, while at the same time, she could feel both of Spike’s cocks throbbing inside her, perfectly in time with the loud heartbeat in her ears. “Ahh...everything sounds fine, here...” she moaned, moving the little metal piece around Spike’s chest a bit, listening to the big organ beating and thumping powerfully.

Spike growled a bit from the feeling of the cold metal pressed against his chest, but kept thrusting nice and hard, panting a bit and snorting more black smoke as he felt the pressure slowly begin to build up within him once more, loads of precum flowing into the mare’s orifices as his members twitched and throbbed more quickly with his quickening heartbeat. Gripping her legs a little tighter, he started making slower, but harder thrusts, really pushing those two cocks deeply inside the mare, making her moan out blissfully and close her eyes tightly from the pleasure.

“Ooh, yes...pound me, Spike!” Goodall cried, her cheeks tinting a deep red again from the surge of pleasure, causing her insides to squeeze a bit tighter around Spike’s thrusting shafts, her own orgasm steadily building up within her as she continued to listen to the dragon’s thundering heart. Her own ticker was racing as well, spurred on by the deep thrusts from the lustful dragon, panting heavily from the wonderful pleasure it provided. After a few more moments of listening to the heartbeat thundering in her ears, she pulled off the stethoscope and opened her eyes slightly, just enough to gently toss the device back over onto the counter.

Reaching her hooves up, she gently grasped Spike’s shoulders, glancing up at him with a lustful look in her eyes, still panting and moaning as she was bucked so firmly. “Nnnh...Spike, darling...I need you to...nhh...lay on your back...for a moment.” she said between her panting, the dragon grunting a bit in response and squeezing her legs tighter before leaning backward, rolling onto his back with a thud against the table, leaving the mare on top of him now in a nice cowgirl position.

“Ooohh, yes...nice and deep...mnh...my horny dragon.” the mare groaned loudly in bliss, taking in every inch of both members each time she came down, her warm juices having completely coated the one in her pussy as her orgasm drew closer and closer; feeling the twin cocks throbbing harder within her as well, about to erupt any minute now. “Nnh, just one last test, dear...” she softly spoke, pulling a tongue depressor out of the jar of them nearby, keeping her other hoof pressed to the dragon’s chest as she kept riding him nice and fast.

“Say...”Ahh”...mnh, for me, deary!” she moaned, trying to hold the tongue depressor in her teeth as she leaned down towards Spike’s face, closing her eyes to shield them from another snort of black smoke. Instead of getting an “Ah” from the dragon though, she got a blissful roar from him, his maw still opening nice and wide, allowing her to press the little wooden stick against his tongue and look inside his mouth.

“Looks healthy, Spi-aaah!” Goodall gasped in bliss, leaning her head back as two streams of hot dragon seed suddenly gushed inside her; Spike’s claws grasping her flanks firmly and digging his claws into her skin a bit as he climaxed powerfully, flooding the mare’s insides with his steamy essence. “Ohh, my...Spike!” she moaned out loudly, closing her eyes tightly as the sudden filling only helped to push her over the edge moments later, her warm orifices squeezing around Spike’s cock like a couple of soft, hot vices, releasing a torrent of her carnal juices over the member in her pussy, splashing out onto the dragon’s belly along with a good amount of his seed, which was more than enough to creampie the mare.

Shuddering from the blissful pleasure, Goodall sighed contently after the powerful orgasm, collapsing on top of Spike and panting heavily with him, resting her head on his neck as she lightly wrapped her hooves around him, blushing and smiling a bit as her afterglow kicked in. “Mmnh...I never knew playing with a dragon could be so much fun...” she thought out loud with a soft giggle, loving the feel of the steaming-hot seed inside her, filling her lower body with a feeling of immense warmth, only adding to the feeling of being stuffed full of dragon meat.

“I take it you enjoyed yourself too, my horny little dragon?” she added as she sat up a bit, glancing down at Spike, who was still panting deeply and growling softly with his tongue hanging out the side of his mouth, a look of bliss on his face as he nodded softly. “Hehe, good...” the mare giggled and nuzzled his snout gently, giving it a soft slurp before gently pulling herself up, sighing lightly as she felt the liquids inside her slowly releasing after Spike’s twin members left her, the mixture of dragon cum and mare juices splashing onto the table below.

“Let’s get you back to your owner then, deary.” the satisfied mare spoke, quickly wiping herself and Spike clean with a towel before unlatching the door and opening it, motioning for Twilight to come in with a soft smile. The unicorn grinned lightly in return and got up from her seat, trotting over to the door and glancing inside, seeing Spike sitting on the table still, albeit now with a satisfied grin on his face.

“Well? What’s your diagnosis?” Twilight asked curiously, raising an eyebrow as she swore she could smell body odor and semen in the room, but shrugging it off, knowing that many animals were in and out of this room all day. “Is there a way to reverse this growth?”

“I’m not too sure, to be honest.” Goodall replied, rubbing the back of her head gently. “I couldn’t find anything wrong with him after a full physical inspection. If you want I can see him again tomorrow for some more advanced tests. Might be able to diagnose something causing the growths.” she suggested, smiling inconspicuously towards the unicorn. “I would have done more advanced tests today, but the equipment is over in Fillydelphia for the day...it should be here tomorrow though.”

“Hm...I see. Guess I’ll just have to keep him under control until tomorrow, then.” Twilight nodded, before gently grasping Spike’s claw. “C’mon Spike, we’re going home.” she added, watching as the big dragon hopped off the table, smiling over at the yellow mare as Twilight led him out of the room. Giggling softly, Goodall waved to him, sighing happily, already eagerly awaiting the dragon’s next visit.

THE END
