Peering into the darkness, Rainbow Dash strained to see more than a few feet, being forced to cup her hoof against her forehead in order to help her eyes adjust. Sure enough, the darkness of the cave slowly melted away, and far in the distance she could see something faint shimmering in the dark. With a smirk on her lips, the pegasus pushed her pith helmet further up on her head, and began the slow trek deeper into the mountain.
It had taken days of tracking, weeks of study and more late nights then she could count, but at long last her search seemed to be bearing fruit. The glint of gold at the end of the tunnel hinted at the possibility that the lost hoard of Stormbreaker the red could lie a mere hundred feet away.
The pegasus rubbed her hooves together and snickered, already imaging the fame, glory and fat stacks of bits she would make from this discovery. She wondered if she might even be lucky enough to even find the lost amulet of Amon-Ka.
With dollar signs in her eyes the pegasus picked up the pace, creeping down the cavern and keeping an eye out for any traps. She was disappointed to find that the walls appeared natural, meaning there would be no traps to make things interesting. She kept her eye out anyway, hopeful there would at least be a pitfall trap or something, otherwise this was going to make for one boring story.
I just walked in and took it. Didn't sound very good, but if all else failed she could always embellish some parts.
The glint of gold caught her eye again and she had to stifle a gasp as she got closer, noticing that singular flash from before was now joined by a metric ton of others. The pegasus’ jaw hung open as she left the tunnel behind and stepped out into a large cavern with an enormous pile of gold in the corner.
“Whoa.” She mumbled, her eyes being drawn upwards to the truly giant ceiling and equally massive area that the cavern occupied.
Unlike the other area this seemed less natural, with the majority of the cave appearing to be half melted, half chipped away by something, leaving the walls relatively smooth. Yet despite the massive, mostly uniform nature of the cavern, there didn't seem to be any other way out, and there were no signs of another being residing within.
“Weird.” The pegasus remarked.
Glancing at the gold pile, Rainbow Dash quickly noticed that there were more than just coins, but also gems, weapons, jewelry and all manner of expensive looking baubles. She was tempted to start stuffing the expensive looking objects into her saddlebags but she resisted the urge for now, hoping to find the one object she knew was worth more than any other. Setting aside her bags for now, she took to the air, flapping her wings in order to further scan the massive pile.
And It was truly massive, towering well above a normal house, yet despite her search the pegasus couldn't seem to find hide nor hair of the elusive amulet she had sought for so long. She redoubled her effort, hoping against hope to find the legendary artifact that was rumoured to have the ability to allow the wearer to adapt to any change, effectively making the wearer immortal as well as invincible.
She pushed a little higher, only to find no trace of the amulet, on and on she went until she neared the very top. Only when she finally crested the massive pile of gold did she catch a glimpse of something red, her mind instantly putting the pieces together, and remembering that there was a red ruby that served as a centerpiece to the fabled amulet.
She dove down, finding just such a ruby poking out of the very top of the gold pile. The pony said a quick prayer to whatever deity was listening, thanking them for not only striking down Stormbreaker like the rumours foretold but leaving his hoard and more importantly, the amulet, in tact.
With her prayer done she dug through the top of the gold pile, tossing aside more bits she had made all year in order to get at the treasure beneath.
“Aha!” She yelled, snatching the amulet from the pile.
She lifted the amulet up, intent on setting it around her neck, only for something to snag. Looking down she gasped, noticing a clawed hand gripping the amulet. “Hey this is my amulet buster!” She yelled.
She grabbed the artifact with both hooves, flapping her wings hard, trying to tear the treasure from the creature’s grasp. Coins cascaded down the treasure pile, gems and baubles bouncing across the cavern floor and though she seemed to be making some headway it wasn't much. After several seconds of struggling she looked back at the hand, hoping to find that it’s grip had loosened at least somewhat.
Only to nearly let go of the amulet when she saw a pair of red beady eyes poke out from beneath the mountain of gold. Turning back, the pegasus pumped her wings harder then she ever had before, inadvertently dragging the dragon out of the gold pile and into the stale air of the cavern itself.
With the dragon now freed of his golden prison he breathed deep, filling his lungs and making his body twitch as it slowly returned to life. Rainbow Dash, not realizing what she was doing, hardly even noticed until the dragon’s other claw reached forward and grabbed the pegasus’s back hoof. Flapping as hard as she could had unfortunately accomplished nothing and the pony was dragged down to eye level of the dragon, revealing that he wasn't much bigger then she was.
He was thin, gangly, with a pair of stubby wings that wouldn't be able to support even his insignificant weight. His snout was a little longer than most, and he lacked any of the cartoony proportions that other teenage drakes seemed to have. He wouldn't have been very intimidating if it wasn't for his blood red scales, and somehow even deeper red eyes that seemed to seethe with an intelligence more intimidating than anyone Rainbow Dash had ever meet.
“Hello, thief.” The dragon announced, his voice deeper then any Rainbow Dash had ever heard.
“Uh, hi. Don't suppose your just gonna let me go huh?” Rainbow Dash blurted.
The dragon chuckled, a deep resounding laugh that seemed to echo from the very bowels of his very soul. “No, I’m afraid not. Though I find myself weakened and out of touch with the world. Perhaps a trade would be in order.”
The pegasus’ eyes lit up. “Well, I’d rather race you for it but I suppose a trade could work.”
The dragon nodded. “Good. I had hoped you'd say that. I’ll ask you a series of questions, and then if you can beat me in a physical challenge I will let you keep the amulet. Do we have a deal?”
Rainbow pretended to think about it before smirking and sticking out her hoof. “You got a deal Red!”
The dragon bumped his fist against the pony’s hoof, a sly smile spreading across his lips. “Now then, what year is it?”
The pegasus blinked. “Uh, six A.M.”
“I asked for the date not the time.” The dragon rolled his eyes.
“That is the year. Fifteen after moonfall. They switched the calendar after Luna’s return and the start of a millennium.” Rainbow Dash stated.
“Interesting. Now tell me, did you come here alone?” The dragon asked.
Rainbow Dash smirked. “Yup! I’m going to surprise my friends with the greatest archaeological discovery since Daring Do managed to find the crystal skull!”
The dragon snorted. “Great, that other thief is still around, wonderful.”
“Hey! Daring Do isn't a thief!” Rainbow Dash exclaimed angrily.
The dragon smacked Rainbow’s accusatory hoof out of his face and snorted. “It hardly matters. Now onto my last question before our little contest.”
“Uh speaking of contest what exactly were you thinking? Because I don't think those puny wings would really be a match for me.” Rainbow Dash pointed out.
The dragon grit his teeth but held back his remark. “When I return to my full strength I would easily be able to best any mere pony in flight but no, that is not what I had in mind.”
The pegasus shrugged. “Alright, what's your last question?”
“Simple, does anyone know your here.”
The pegasus’ eyes narrowed. “Why do you wanna know, huh?”
The dragon shrugged. “I was just wondering if I had to worry about someone else coming by and stealing my things.”
Rainbow Dash stared at him for several long seconds before shrugging. “Nah, like I said, this is all a surprise. It's going to be epic!”
“Right, epic.” The dragon rolled his eyes.
“So, what's this challenge? I’m ready to whoop your butt!” Rainbow Dash announced proudly.
The dragon chuckled, using the amulet they were still holding onto pull the pony closer to him. “It's a simple test of endurance, If you can make me cum, I will let you take the amulet. So simple even you can understand it.”
“Hey! I can so understand it and you are so on! I can take anything you can throw put out. I once fucked a minotaur.” The pegasus announced proudly, lifting her chin and smirking.
The dragon chuckled darkly. “Those beast men are nothing compared to me.”
“Pfft whatever perv, their dicks are huge.” The pegasus blew raspberry dismissively. “I can totally take ya.”
The dragon yanked the amulet closer, drawing the pegasus mere inches from his fiery eyes. “Is that so?”
Rainbow’s eyes narrowed and she glared right back. “It is totally so.”
A sly smirk slowly crossed his face and he gestured down to his waist. “Well, I’m waiting.”
Rainbow Dash scoffed. “This is going to be…” Her jaw suddenly fell slack, her gaze lingering over his truly massive endowment. “Easy?”
“What's the matter thief? Cat got your tongue?” The dragon teased.
Rainbow Dash couldn't even muster a response, her gaze stuck on the dragon’s truly gargantuan dick. It was easily half as large as the pegasus herself was, and massively thick. She had no doubt that if she would somehow manage to put that thing inside her that she would be ruined, if not dead.
The pegasus shook her head. “Nuh uh, no way. That thing might kill me!” She let go of the amulet and flew back a few feet. “Not worth it.”
The dragon spun the amulet around on one of his fingers. “What, giving up so soon? I thought you could take ‘anything I can throw at you’?”
Shaking her head, Rainbow Dash scoffed. “It's a matter of biology man! I can't take something that big it's impossible.”
He smirked. “Not with this it isn't.” He held up the amulet, angling just so it catches the light.
Her eyes narrowed. “You’d let me wear it while we did it? That's awful trusting.”
“Oh trust has nothing to do with it. I will keep one hand on a wing and if it seems like your about to fly away with what's mine.” He made a twisting motion with his hand before wrenching it back, pantomiming the act of tearing out her wing.
The pegasus gulped, wanting nothing more then to leave but finding her gaze drawn back to the amulet. “Okay… but no rough stuff! Got it?”
The dragon made an X over his heart. “I promise.”
He extended a hand, offering the amulet while the other reached for her midsection.
The pegasus made one last glance at the exit before steeling herself, imagining what would Daring Do do in this situation? With her confidence rebuilt she grabbed the necklace and slipped it over her head, feeling the dragon’s clawed hand wrap around her midsection.
“Alright so how are we going to do this? Cus I didn't see a bed around here.” Rainbow Dash pointed out.
The dragon laughed his deep, intimidating laugh. “No little mare. There are no pony beds around here, however there is a dragon bed.”
Rainbow Dash looked around, only to find the same mound of gold she had seen before. “All I see is money.”
“Sleeping on or in a pile of one’s possessions is a dragon’s bed.” He stated simply, then before she had a chance to complain anymore he gripped her mid section and brought her down to the height of his waist.
The pegasus grumbled quietly but made no complaint, as she was a less than secret fan of a little rough treatment. She wiggled her hooves a little, getting a better grip in the slippery mound of gold she found herself perched atop of. Opening her wings, she parted her back legs, feeling the dragon’s claws wrap around her mid section. His grip was neither loose nor tight, merely a constant reminder of his dominance and the fact that he could squeeze down at any moment. The thought aroused the mare more than she would ever admit and she eagerly glanced over her shoulder, watching as the dragon established his own footing before turning back to her with a smirk.
“You seem to be quite eager. Have you perhaps engaged in intercourse with creatures whom have dicks half as big as you are?” He smirked. “Or am I just the start of a habit?”
The pegasus grumbled silently, looking forward so the dragon didn't see the blush growing across her face. “None of your business, perv.”
Chuckling to himself quietly, the dragon took a moment to gaze down the pegasus’ form, noting her well muscled and athletic body that seemed to be trained to a razor’s edge. It’s almost a shame I am about to ruin it… almost. He thought to himself, his smile growing wide enough to reveal his razor like teeth.
“Well, go on then. You said you’d be able to get me to finish and here I am, waiting.” The dragon remarked.
“R-right.” The pegasus stammered.
Ignoring the dragon’s enormous clawed hands around her midsection, she cast a glance over her shoulder, finding that the dragon’s massive scally cock was mere inches from her holes, a single bead of pre running from the tip. She couldn't resist licking her lips at the sight, her mind fixated on the sheer size of the blob of pre. It was easily as big as her hoof and it splashed audibly when it hit the gold, making the pegasus wonder how big his load would be if his pre was a larger output than most stallions.
“I’m waiting.” He noted with a hint of impatience.
The pegasus gulped once more, pushing her ass back against the tip of his cock and rubbing it up and down. She pushed back slightly, pressing the enormous tip of his cock against both of her holes and smearing another enormous dollop of pre against her holes, thoroughly lubricating her already sopping wet pussy. So great was the dragon’s production that with a single dollop of pre he even thoroughly lubricated the mare’s ass, pushing in a few globs of his abnormally thick cum into her puckered sphincter by accident. The mare shuddered in pleasure, overwhelmed by the feeling of the almost yogurt like cum now residing inside inside her.
She forced herself to brush aside the feeling for now, not wanting to lose the momentum she had. She could feel his cock twitch with need, signalling that he was enjoying it, now she just needed to leverage that pleasure and really drive things home. With a grunt she rubbed the massive head across her holes once more before slipping it a little lower, pushing the massive cock between her well muscled thighs. Squeezing down on the massive appendage with her legs, the pegasus shifted back and forth on the dragon’s scally cock.
Yet despite how awesome she knew her thighs to be, he seemed uninterested, his cock no longer twitching with need and his shaft no longer bubbling with pre. She grumbled silently, slipping further back and squeezing her entire body against the enormous shaft. Still he didn't seem to flinch, even as she nearly curled her entire body around the cock, squeezing and massaging it as best as her tiny body allowed. Still nothing, not even a twitch or a tiny moan of pleasure.
With a grunt she pulled back, knowing that at least he enjoyed it when she grinded her pussy against him. It wasn't much but she didn't want to lose any edge she may have gained and indeed when she rubbed herself against him he did seem to enjoy it. Not by much though and with a growl building at the back of her throat the pegasus was about to turn around and try to use her mouth, only to find his grip tightening around her midsection.
“You seem to be having some trouble. Here, let me help you with that.” The dragon offered.
Rainbow Dash squirmed. “Wait, I can do it just give me a-!” The pegasus’ jaw hung open in a silent scream as she felt the dragon’s claws dig into her waist and something massive press against her ass.
His scaley features twisted as he smirked down at the baffled mare, watching as her body froze, his enormous cock head somehow managing to slip into her much too small hole. Despite the fact that the tip was nearly as large as the mare’s own hoof it slipped inside with only a second of struggle. The dragon’s strength being so great that he was able to push past her resistance and shove the massive head of his cock into her much too small hole, and even then only barely, her body simply too small to accept it fully.
With the absence of a struggle the dragon pushed on, pulling the mare down hard against his cock, forcing several inches of his increasingly massive cock inside her tight hole. Despite the sheer physical differences between his cock and her body, he was able to continue pushing, somehow managing to fit even more inside her. Until all at once she realized what was happening and her hooves began to move once more, trying desperately to find a grip on the loose pile of gold.
“H-hey wait!” She yelled, her frantic hooves sending coins flying as her wings flapped uselessly. “Just hold on a second!”
“Why should I? You said you could take it and yet you didn't seem willing, or maybe you were simply incapable?” He smirked, noting the mare’s struggles ceased for a moment.
It was only a moment however and the mare spun around, glaring at him. “That was before I noticed how big you were! Besides I could still try and suck you off!”
The dragon pressed his hips forward, thrusting into her ass and forcing even more of his mammoth cock inside her. The mare’s next complaint died on her lips, her eyes rolling back in their sockets as she felt the massive cock spread her hole wider then what should be physically possible. Even as the massively girthy pushed on and her hole stretched further than ever before, there was no pain, and no discomfort as her body was forced to change shape to fit his cock. There was only pleasure, endless pleasure.
“Oh. Are you sure you want me to stop?” He asked quizzically, his thrusts slowing suddenly, his hips finally stopping.
The mare squirmed, a blush growing across her cheeks, her wings no longer flapping yet still remaining rigid. The cave was oddly silent, with only the mare’s frantic breathes the only sound. “Well? What are you waiting for?” The mare growled, grinding her hips back and pushing against the dragon’s enormous prick.
“Such a needy slut.” He delivered a hard smack to the mare’s flanks, noting idly that they appeared larger then when they had first begun.
He thrusted his hips, pushing deeper and watching as the mare’s hole grew wide still, accepting his cock with ease despite the fact that it had grown considerably wider then when they had first started. The dragon smirked, noting that the necklace had already gotten to work, the ruby now glowing a bright red, it's energy seeping into the mare’s body as her head was thrown back in a moan. He felt his bones creak, his body shifting and growing larger with each second he fucked the greedy mare.
Rainbow Dash hardly noticed the change, her eyes closed tightly as she felt that massive cock of his as it relentlessly filled her hole. The sheer stretching sensation alone was nearly incomprehensible, it was as if her entire body was being remade to better serve the dragon’s titanic erection. It's truly gargantuan size meant that even after a few seconds of pushing it had already reached deeper than anything ever had before. Easily gaining the title of the largest thing she had ever put in any of her holes, it's girth so massive that she could feel her organs getting shoved out of the way before it had even pushed more then six or seven inches inside.
Hot smoke billowed from the dragon’s nostrils, his clawed feet sinking deeper into the mass of gold as his height continued to increase with each passing second. Horns grew from each side of his head, his wings extending far past their previous size all while his cock continued to grow in proportion with him.
Rainbow Dash could hardly tell the changes had even occured, the feeling of stretching, distorting, and overwhelming pleasure remaining a near constant throughout it all. It was so mind crushingly powerful that she wasn't even aware as her ass began to grow larger by the second and within a minute it had reached nearly porn star levels. The sensations were relentless however, giving her no time to react to the previous change before a new wave of pleasure ruined any coherent thought she could manage.
The dragon grinned, his mouth having grown large enough to easily swallow the mare whole. “Having fun, pet?” He growled, his voice having grown considerably deeper.
Rainbow Dash groaned, her body wiggling in his grasp, desperate for more of his hot dragon cock. “N-no.”
“Really now? Because your body says otherwise.” He smirked, slowing his thrust and watching as she began to flail around, desperate to feel his touch.
The pegasus growled, wiggling her hips as much as the dragon’s grip would allow. “Come on, hurry up already!” She whined.
The dragon rolled his eyes and resumed his thrusting, watching the mare’s face as it grew bright red, unable to hide her blush from the now much taller dragon. Shaking his head, the dragon redoubled his grip on her waist, releasing one hand as the other was now easily large enough to wrap all the way around the pony’s body by itself.
The first thrust sent a surge through the pegasus mind and reminded her that he had yet to even bottom out inside her. It was intimidating to think of, imagining the size of his cock and realizing that there was still so much more left outside her body. Another push, another few inches of hot draconic cock, and the mare was reminded once more of the sheer impossibility of it all. She was vaguely aware of the now massive bulge the dragon’s cock made in her stomach, the outline of his dick clearly visible through her skin. Running a hoof down her belly, the mare could feel every bump, groove and vein of the dragon’s massive cock, making her shudder in unexpected pleasure of the feeling.
It was so unlike anything the pegasus had ever experienced, catching her completely unaware and filling her mind with such pleasure the likes of which the pegasus had never experienced. Every thrust made the bulge grow, each movement causing her body to stretch and change even more, the cock forcing her to adapt lest she be crushed by it's magnitude.
The dragon smirked, noting that over half his cock was inside her, yet there was still as much length left outside her then when they had first begun. One massive clawed hand gripped the side of the gold pile, his hips thrusting forward, the mare watching closely as the bulge in her midsection grew, as did the light emanating from the amulet she wore. The magic within was having to work overtime, forcing the pegasus’ body to adapt and change as she took more and more of his cock.
Despite his fascination with watching the changes and the magic of the amulet as it did it's job, he had run out of patience. He wanted, no, needed more. He needed to bury himself inside her, to fill her, to ruin her and make the mare his own. With a roar that made the walls tremble, the dragon thrusted forward with all the strength he could muster.
Feet of cock roughly shoved themselves inside the mare’s body, making her mind blank and the magic work harder then ever. For the first time the pleasure was tinged with pain, even the amulet struggling to keep up with enacting the changes that were needed in time. Organs were pushed aside, muscle and bone shifting in order to accommodate the monstrous invader. Her ass ballooned after the thrust, growing to such a massive size as to easily dwarf even Celestia’s impressive posterior. Yet it still wasn't enough, he had cock to spare, and the mare was running out of space inside her tiny body, the bulge rapidly approaching her ribs.
The sight would have made any pony stop and stare, yet the dragon didn't bat an eye at the sight, knowing exactly what was about to happen. With a smirk on his lips he pushed forward relentlessly, watching as the bulge grew and grew.
Rainbow Dash could feel her breasts begin to tingle, the strange warmth that had centred on her butt extending down into her tits. It was faint at first, easily excused as little more than a strange reaction to the sheer amount of pleasure running through her brain. Yet as time passed it continued to grow, only to be pushed aside as a new wave of tingling overcame the forefront of her body, centering around her torso.
A sudden shove, and the bulge lurched up the mare’s body, making her grow and shift once more, turning into her a living cocksleeve. The dragon breathed heavily, his sulfurous breath filling the cavern. He slowed for a moment, feeling mere inches left outside the confines of his newest pet’s hole. Glancing down he watched as the mare’s tits grew to truly mammoth proportions, something the mare herself didn't seem to notice, her mind too overwhelmed by the changes taking place in the rest of her body.
Her breasts jiggled, her already titanic tits trembling as new changes began to happen. Her breasts surged outwards, growing as large as the mare’s head and showing no signs of stopping. A red glow suffused the winged pony’s tits, signalling that the changes had much further to go before they were complete. When her tits finally stopped growing they were as large as a full grown pony each. The magic that grew them shifting back to the rest of the mare’s body, ready to alter the rest of her form in order to contain the dragon’s titanic appendage.
The last few inches surged into the seemingly endless depths of the mare’s ass, filling her to absolute completion and causing her entire body to shudder as even more modifications were made to her body.
Rainbow Dash felt heavy, the cock inside her felt like a giant log rammed up her ass, yet the feeling of weight didn't end there and she felt an oddly cool sensation coming from her crotch. Her legs hadn't given out, meaning she hadn't fallen into the pile of gold yet she could still feel it's cold touch against her breasts.
She could only give the strange feelings a few moments of thought before the dragon thrusted forward once more, ruining her ability to think rationally. It was as if the dragon’s titanic cock occupied not only the entirety of her ass, and most of her body but also her very mind. A mind that was currently filled by the strange pleasure that came with the unimaginable stretching that seemed to begin at her crotch and end near her throat.
With his cock now finally resting completely inside the mare’s cramped body he was finally able to really submerge himself in the act. The amulet had done it's job and had remade the mare’s form into something more suitable to serve as a true dragon’s mate. He had no doubt that she would be capable of taking his load, though he had his doubts that a pony without the amulet could do such a thing without perishing in the process. He shrugged, confident that the artifact would keep her alive, though the status of her mind would no doubt be a different story entirely.
Thrusting his hips forward the dragon gripped the mare’s waist which had grown along with his cock, to the point that it almost felt as though he was jacking himself off with an oversized sex toy rather then fucking an actual being. Even such a strange realization did little to dampen his own arousal, serving only to make his already wide grin grow ever larger.
He was so close to truly claiming this mare’s body for his own purposes, with every thrust he could almost feel her mental walls crashing down. Her wings stood as rigid as before, occasionally flapping randomly when a particularly powerful surge of pleasure coursed through her. Her tongue hung from her mouth and all four of her limbs hung limply, held aloft by the dragon’s massive hand and nothing else.
Throughout it all she was still as perfectly tight as the very first thrust, her body somehow able to grow just enough to take him but not so much that she became loose.
Having finally grown able to hilt the mare properly his enthusiasm only grew and he gripped the mare tighter, dragging her along his cock as he continued to grow. Gold cascaded down the side of the mound, the dragon shifting his weight and turning until he sat in the centre of the golden mass, using the plethora of coins and valuables like an oversized bean bag chair. In his hand he continued to fuck the adventurous thief, his clawed hand having grown large enough to grip the mare’s entire body at once, with only her now massively large breasts and ass escaping his grip.
The dragon leaned back fully into the mountain of gold, reclining in pleasure as he moaned. It was a deep, rumbling sound that shook the entire cavern, a stark contrast to Rainbow Dash’s high pitched squeals of pleasure. A sound that became even higher pitched when the dragon started using her faster and faster. Her body became a blur, the mare herself hardly aware of the fact that he was no longer even thrusting but merely getting her body dragged down his cock. Not like it would have mattered, the mare had cum more times in the last few minutes then the rest of the month combined.
It was during one of these numerous, seemingly unending orgasms that she felt his pace increase once more, only this time it felt different. His cock pulsed and twitched with need, as if he were drawing close to the inevitable. Some faint part of the mare’s mind that was still capable of thinking rationally wondered if her body was even capable of containing his no doubt prodigious seed. Alas that part of was no longer in control, and despite the risks, she needed to feel his seed inside her almost as much as he needed to empty his balls into her.
A few seconds later the dragon’s cock twitched once more and when the mare’s enormous ass impacted the hard scales’ of the dragon’s crotch she was rewarded with the distinct sensation that heralded the male’s orgasm. The mare swore she could feel the dragon’s balls churn with seed, his shaft so large and occupying so much of her body that even the smallest changes were immediately noticeable.
It didn't take long for the dragon’s thrusts to slow and a deep bellowing roar to fill the cavern, signalling his coming orgasm. That deep resounding roar was unlike anything Rainbow Dash had ever heard, the noise growing so loud that it made her very bones rattle. That wasn't the only thing she noticed, as there was something else just beneath the roar that drew her attention. It was not only the sound of victory but also of dominance, and she knew then and there that she had just been claimed by this monstrous creature.
She could feel the first surge of cum the second it pressed inside her, the massive dragon’s cock bulging as the liquid traveled into her. Which in turn forced her body to shift and change as the enormous load of semen shot inside her. The wave of cum stretched her in ways she had never imagined and in the span of mere milliseconds she was met with another new sensation. One that came with the fact that something truly massive had been deposited deep into her body.
Litre after litre of cum exploded inside her, forcing the amulet to glow bright red once more as it raced to keep up with the changes needed to keep it's bearer alive.
Organs were pushed out of the way, muscle stretched and skin grew, all in a frantic attempt to keep the growing loads of semen inside her body. The mare’s legs dangled uselessly from her body, her wings and limbs twitching sporadically as load after load of cum splashed inside her. Her tongue hung from her mouth, her head loosely laying against her body, her eyes wide and unseeing, too overwhelmed by the changes and the pleasure. The pleasure that was so great and terrible that for a moment Rainbow Dash forgot who she even was.
His hips surged forward even further, somehow managing to cram even more cock inside the mare’s already stuffed hole. The pegasus was faintly aware of the sudden thrust, as a pressure built at the back of her throat, until suddenly she felt even that part of her body violated by the titanic cock. Her throat bulged and her mouth filled with seed, spilling past her lips as she felt her entire body from ass to lips occupied by the dragon’s erection. With one last thrust she felt her jaw creek and open further then what should be possible, allowing the dragon’s cock to push all the way through her.
She watched in awe as an enormous stream of cum shot from the cock sticking out of her mouth, her mind so addled that even while she should be panicking, she felt only pleasure. The dragon pulled back his hips, suddenly realizing that the amulet may not be able to keep up with the changes, and he didn't feel like losing this newest slut quite yet. Rainbow Dash watched as the cock pulled back, receding past her lips and down her throat before going back to residing deep inside her bloated body.
Her complete senses only seemed to return to her when the dragon’s orgasm began to die down, his enormous cock no longer twitching inside her. Yet even after realizing what was happening, Rainbow Dash still didn't care what was happening. She could feel her stomach was now larger than the rest of her body by several degrees of magnitude, her breasts each growing far larger than should be equinely possible. They were titanic, easily several feet across and heavier then the mare had been only a few minutes ago.
Even with the knowledge that she would never fly again, Rainbow Dash didn't care. All she wanted, all she did care about was more, more cum, more seed, she needed to grow larger still!
The dragon lay panting on his mound of gold, reclining on the pile of valuables with his head thrown back and his entire body relaxed. It felt good to have finally healed up enough to walk around, and even better to have finally emptied his balls for the first time in decades. He glanced down to his now much larger appendages, a thin smile crossing his lips. Greed had done wonders to fill out his form, making him grow to a portion of his former size.
His musing was interrupted by a sudden squirming at the end of his cock, drawing his gaze down to the squirming pony impaled on his dick. As he watched the pony writhe around he couldn't help but chuckle, evidently the thief he had caught was a better catch then he had first thought.
Despite the fact that her body was now almost nine tenths belly, ass and tits she seemed unperturbed by this and was instead annoyed that her mate had stopped so suddenly. The mare grinded her hips back, trying to wiggle her body along his length only for it's sheer size to make any such movement a complete impossibility.
“Come on! I need more! More more more!” She whined, trying to move around on his dick.
He smirked. “Ready for more so soon?”
“Fuck me already.” She growled back. “Fill me! I need more, please for the love of Celestia just fuck me!”
The dragon chuckled, noting the mare’s mind seemed to be gone, leaving behind a desperate slut that only wanted more
With a smirk, the dragon shifted his weight slightly, dragging the flailing mare down his length until finally the tip of his cock popped out of her hole. Surprisingly the act was met with only a thin trickle of cum that dribbled out of her ass, her body having somehow contained the unprecedented amount of cum. Holding her body aloft the dragon watched as she continued to flail until suddenly falling still, her lungs quickly running out of breath.
Not one to leave a mare waiting, the dragon gripped her in one massive hand, dragging her now surprisingly heavy body back down against his cock. The mare’s squeal of delight was stifle a moment later when she felt the dragon’s cock slam into her pussy, making her eyes go wide in shock. Only for her mind to go blank as she was forced to relive the incredible sensation of having her hole stretched far larger than what should be physically possible.
This time was different though, this time his cock did not grow along with her, giving her time to adapt and change along with his cock. An appendage that was now as long as she was and nearly as wide. The feeling of her body being wrenched open, and the dragon’s cock being pushed inside was beyond even the stretching her ass had just received. Her muscles spasmed, her wings flapped randomly and her limbs twitched as her body was overcome by the strange sensations flowing through her.
She could feel as his massive cock pushed deeper, forcing her body to grow once more, the enormously powerful head splitting her apart. A second later the amulet flashed and the changes caught up with the dragon’s advances, allowing him to push deeper. But that didn't mean the mare was mentally ready for what came next and she only barely managed to stay conscious when he stuffed even more of his cock into her brutalized hole.
Her womb shifted, the rest of her body following suit as he pushed on. This time there was no bulge in her midsection as her stomach had grown to truly disturbing proportions. The only way she could track her new lover’s progress was by the way her body shifted and contorted as it adapted itself yet again. This feeling of stretching and change was somehow even greater then the last time, and even with her experience she found herself nearly blacking out from the mixture of pleasure and pain.
The amulet seemed barely able to keep up and all too soon she felt a fresh surge as the dragon pulled her deeper on his cock. The mare’s jaw fell slack, her entire body following suit a moment later. She had thought she had given up and allowed the pleasure to rule her before but she had been terribly wrong. The feeling of having her pussy violated so thoroughly and so violently was beyond the ability for words to describe and she found herself falling into an endless abyss.
She was distinctly aware of the fact that she could feel the last dregs of control fading over her mind and body, leaving her uncaring as to what even happened to her. Whether he continued or stopped, it was all irrelevant, as she was nothing more then an overfilled condom, a toy, nothing more then an object to be used, filled and tossed aside as her new master willed.
The amulet had yet to do it's job, unable to keep up with the changes necessary to contain his massive endowment. As such she was tight, to the point that even when her entire body fell slack and her mind left her, her pussy was still a vice. Which fit the dragon just fine, as it wasn't like he cared one way or another.
Twin clouds of smoke billowed from the dragon’s nostrils and he pulled hard, forcing the mare down further and further until finally she rested against his crotch once more. With a smirk, he looked down at the enormously bloated form of his newest cocksleeve and noting her glazed and distant eyes. Her entire body was held aloft on his cock once more, his shaft even able to support her surprisingly heavy stomach.
For a second he remained still, merely willing to watch as she hung there from the end of his dick. “Where did all your fight go?” He asked.
The mare didn't answer, limbs still slack, her gaze still distant.
“You know the amulet might enable me to knock you up you know.” He leaned closer, whispering hotly in her ear. “Think of it. Hundreds of eggs all growing inside you until finally you’ve grown so massive that you don't think you could possibly take anymore only to have to give birth to our numerous progeny.”
He remained there for a moment, waiting for her response, only to receive nothing in reply. Leaning back, the dragon let out another deep, rumbling laugh. “And so the tiny thief has finally been broken.”
The dragon’s eyes glinted with cruel intent and he regripped the mare’s body. “Let the real fun, begin!”
Hours later.
The dragon was now coiled about Rainbow Dash’s body, his stature having grown to the point that he could have probably stood over Canterlot castle with ease. His wings had grown to fit his body, the span of which could probably darken the skies over a small village. Teeth as long as swords now jutted from his jaw, and his every breath caused a billow of smoke to rise to the top of the cavern before dissipating through some unseen vent. His smile was content, his eyes closed as he drifted off into a deep slumber, completely satisfied.
Meanwhile, the mare’s jaw hung open, her gaze as distant as ever, the only sound being her labored breathing that only barely kept up with the demands of her now grotesquely large body. No thoughts flickered through her mind, her limbs remaining as immovable as ever. Not like it would matter anymore, as her legs were now only about one one hundredth the size of the rest of her body. Nevermind the fact that her draconic lover was wrapped around her, his cock still lodged deep inside her body, occasionally pumping another few litres of semen into her increasingly bloated body. She was no longer the fit, athletic mare she once been, now she was little more than a massively oversized cum balloon.
Her stomach had grown to the point that it was nearly the size of the dragon’s hoard and by extension, the dragon himself. Hundreds of litres of hot dragon spunk swirled inside her holes, filling every nook and cranny of her newly altered body. Escape was utterly impossible as she weighed over a hundred times that of which she had this morning. Her tiny legs and wings could do nothing to move such a massive bulk, not like she even wanted to.
Her mind was well and truly gone, leaving her as little more than an oversized cock sleeve, and eventually, a egg making machine.
