To call Rick von Bach a thief would be akin to calling a high knight of the realm a common warrior. He was a burglar, and was one of the greatest burglars that lived in the kingdom for one reason and one reason alone: he had never gotten caught.

There was a trick to it, a secret that not many others in his line of work had learned: you had to not get greedy. It was the most important thing that Rick had learned in his life, and it had kept him from many a trap.

Of course he was nimble and spry, which certainly also helped—but the ability to rein in his lust for treasure was his greatest asset. If he'd cased out a home for a specific jewel, he never risked picking a hidden chest and risking an alarm. If his aim was to grab treasure, then he would only grab as much as he could carry.

Indeed, 'Take only what you need' was the motto that Rick lived by.

This is the story of how that all went to hell, and it all begins on the side of a cliff.

Rick had been struggling up a mountain for the past few hours. His hands were numb, his muscles were aching, and he was sure that his climbing gear was more than a little bit worn.

But if this paid off, it would be more than worth it. This job would be more than a simple burglary; it would be a masterpiece for everyone in his line of work to follow by.

Today, he was going to be the first man to rob a dragon.

Of course he wouldn't be the first person to rob a dragon. Dwarves and Elves did it all the time, and there were a few magical folk to hazard such an attempt. But for those of the race of man, with plodding feet and large bodies, the feat was unheard of. Until today.

Rick crested the lip of the cave with a quiet huff, rolling onto his back to catch his breath. He'd been watching this cave for weeks now, and he knew that the dragoness who dwelled here would be asleep at this time.

He also knew that there were legends of her untamed ferocity; that none were able to come close to slaying the beast known as Sapphire and that she'd built her hoard upon a mountain of skulls.

She was perfect: a mythical foe who'd give Rick such status that he'd likely be elevated to a lesser noble for his deeds. If he was able to steal from her properly without her burning him alive. But that was just a job hazard.

Rick looked deeper into the cave to see a golden shimmer and he looked into it with a contented grin, stopping only to check that the herbs he'd bathed his clothes in were still masking his scent. They were, so he was able to press onward, creeping from rock to rock until he could see the hoard.

And what a hoard it was! His eyes widened as he looked upon the gold that filled the cavern, such vast treasures that they nearly eclipsed the slumbering sky-blue behemoth atop their peak.

Rick calmed himself with a few deep breaths; then he took a nervous step towards the dragoness. His foot made no discernible sound to his ears, but that didn't mean that he was being quiet. Thankfully, Sapphire didn't so much as stir in her sleep.

Rick grinned happily as he increased his pace, looking throughout the caverns to find some treasure he could take home to call his own. He needed to prove he was here, after all; and common trinkets could come from anywhere.

Then his eyes lit up at the sight of a ruby in the pile, an ornate thing whose core seemed to burn with dragonfire. It was like nothing he'd seen before and it was even lying atop the other treasures, ensuring that he could lift it without Sapphire so much as stirring.

His hand wanted to tremble as he reached for it, but he forced it still. This would be his triumph, and he could afford no error. The rest of the world around himself seemed to draw to this one point, to focus on this one solitary gem.

And just like that, he snatched it up and stuffed it in his pocket, quick as can be. He had done it. He had burgled the beast, stole from an apex predator. All he had to do was leave, and... Rick paused, looking back to the pile to see a gold coin shimmering back at him, a dragon emblazoned on it.

Well, what harm could possibly come from taking one more? Rick thought to himself, his eyes shimmering as gold as the disc which glittered before him.

For those of you wondering as to this sudden change of character, there is a simple explanation which had yet to travel to our poor thief. The reason why only a select few were able to rob dragons were because there were powerful magics about around each dragon's hoard.

Dwarves could steal from them thanks to an innate immunity to witchcraft. Elves and wizards were bathed within the magical arts for their whole lives, and so were able to dispel charms that were placed upon them. But men, who were the most susceptible to charms, were innately weak to their curses.

So it was that Rick had accidentally damned himself with the theft of a simple enchanted gem, a ruby emblazoned with Sapphire's strongest desire, the desire for another dragon to warm her cavern—and to 'warm her cavern'.

This desire had already begun to work its way along Rick, giving him a pair of golden slitted eyes that matched any other dragon's. This transformation also had another effect: it made the treasure look even more appealing to the thief.

He trailed his tongue along his lips with a grin, not noticing how it had begun to bifurcate, the two tips of his appendage beginning to taper to draconic points. He didn't notice how his nails were sharpening; his teeth drawing to small fangs.

The only thing our would-be-burglar noticed was how shiny this little coin was. He reached a changing hand to it and plucked it from the pile with a grin, slipping the little disk into his pocket.

As he did, a tingling coursed all over his body, his hair pulling back into its pores as royal blue scales crept out from beneath his skin, a rippling tide pushing its way from his flesh. He shivered as they trailed down his back, and he swept his head around the cavern in search of something else to purloin.

Then Rick's eyes lit up on an ornate gold crown, and he beamed to himself. What harm could a simple crown do? He grinned as he stealthily slid his way over to it, picking it from its pedestal and placing it atop his head.

The second the gold made contact with his scaly scalp, his tongue slipped from his mouth, becoming thinner and longer as it split to a proper dragon's tongue. He grinned to himself with pride, thinking only about how regal he must look with the crown on his head.

As though sensing his thoughts, the transformation swept throughout his frame, making him grow larger to a size that befit a king. Of course his burglar's clothing wasn't capable of restraining such a mighty bulk, and as muscle rippled below his scales the garb tore at the seams, his sleeves sliding down his arms and his trousers falling to a heap on the ground below him.

The man didn't so much as notice how his body was rippling with change; how even his gut was expanding too a proper size befitting a king. He was only focused on how his fallen pants ensured that his purloined gem and coin were no longer in his grasp.

Frantically, Rick looked around him, his neck lengthening as he searched for something to hold his treasures. He finally caught sight of a large golden chalice, a cup that would be more in common with a wash basin for a common man.

However, the goblet was simply a cup for one of his current size, and Rick swept to it with a greedy grin on his face. It was perfect! As soon as his taloned hand gripped it firmly, another wave of change swept across his body, and the man grunted as large and sharp ridges burst from his back, shredding what remained of his coat and leaving his bulky, scaly form naked in the cave.

Rick didn't care at all; the only thing that mattered was sweeping his treasures into this gem-lined chalice. He darted back to them, his thighs swelling to better hold his weight up as he emptied his pockets into the cup. They clinked loudly, marking his triumph, and the burglar beamed with pride at the sound.

His ears twitched with agreement, flaring out form his skull as they drew to sharp points. He beamed as the echoes of the clinking ran about his mind, and he hurriedly scooped up a handful of coins.

This latest change brought with it an expansion to his hand, his nails drawing to proper claws and his palms swelling to hold more and more treasure. He poured the coins into his goblet, grinning at the sight and sound of them clinking into the cup.

Rick wanted to feel it more, to experience it with his every sense! He laid the chalice down below him and scooped up as much gold as his large new hands could carry; bringing the wealth up to his face.

His slitted eyes narrowed with contentment, and he flicked his tongue out towards them to realize that he could actually taste the treasure on his tongue. Then, with a shiver of surprise, he realized that he could smell the treasure too.

His jaw cracked out form his face, the tip of his nose flattening and pressing back into what was an expanding snout. His nostrils grew larger and he took a tentative smell of the gold, his eyelids fluttering with pleasure at its rich scent.

No wonder Sapphire had accumulated such a hoard! He loudly spilled the treasure into his cup, shivering with pleasure as the loud ringing brought more and more change to his body, making him grow larger and larger by the second.

His back cracked and popped as he grew, his bones thickening to hold his weight; his hips swelling to better accommodate the bulk of his regal gut, a paunch which belied his muscular form. Then his spine started to creak, new vertebrae forming and giving him a draconic tail to match the rest of his body, its tip sharp and flared.

Rick beamed with pleasure, then flinched at the sound of an amused hissing. He turned to find Sapphire watching him with bemused eyes, a smile on her muzzle.

For a moment, panic filled the burglar's mind. He'd been caught; his latest theft was too loud! What would she do to him—and was she always this small?

Rick blinked, realizing that he now stood a head above the dragoness. But instead of questioning this like any sane man would, he instead came to a wild conclusion. If he was larger than her, then he could mate with her; become her alpha. And if he did that, then all of the treasure would be his; he wouldn't need to burgle it!

He considered using his suavest pick-up line, only for it to escape his throat as a dragon's growl. Still, it did the trick, Sapphire's eyes seeming to twinkle knowingly as she turned, presenting herself for him.

Rick grinned, then paused. How could he possibly fit within such a large and scaled cavern? Surely his human cock wouldn't be able to fit the dragoness's needs! He looked down to his groin, and for the first time, Rick noticed the changes that had gripped his body.

His penis was massive, a large and flared tip marking  the end of a swollen head, his veins pumping to keep his mast rigid. He blinked in surprise, cupping it in one scaled hand. Had he always looked like this? More importantly, did he care? There was treasure to be had!

At the thought of the wealth that would soon be his, Rick snapped his gaze back up to Sapphire, a grin spreading across his own snout. Then he pounced upon her, scrabbling on all fours to climb the piles of treasure.

His hips and shoulders cracked further, locking him to a four-footed stance as he ascended the pile. He didn't care; he only wanted to mount Sapphire, to lay his stomach upon her smooth back and shove his cock into her dripping pussy.

Rick could smell her; taste her on the air. The dragoness was in heat, evidently desiring this as much as he did. Her entrance was dripping with a wet musk; her folds beckoning him onwards.

By the time the transforming man had reached her, all sense of restraint was gone from his mind. The hell with any other wealth; right now he had to claim this treasure as his own; fill it with himself! He had to make this dragoness his first; to mark her as his and his alone!

He mounted Sapphire with a lusty growl, his heart hammering in his chest as she responded with a growl of her own. She licked at his scaled muzzle affectionately, wriggling her hips eagerly and sweeping her tail to the side to allow him entrance into her awaiting depths.

And who was he to deny her the pleasure of his thick cock? Rick shook his head, the tiny crown which once adorned his head finally falling from one of the ridges on his dragon's skull. Then he roared, driving himself fully into the dragoness.

Sapphire yowled with surprise, and Rick's eyes widened as she had to squeeze her eyes shut with discomfort. He swept his gaze to her entrance, finding this to be as much her first time as it was his own.

He rumbled apologetically, flicking his tongue along her snout as she had his moments before. Sapphire grunted beneath him, her eyes fluttering as she no doubt accustomed herself to his presence. Then she began to flex her dripping folds, clenching around him as though she intended to milk him.

Rick's eyes widened and a breathless gasp escaped his lips as the greatest pleasure he'd ever experienced filled himself.

Sapphire roared with delight beneath him, spurring him to motion once more. It sounded like she wanted—no, needed—for him to thrust within her, to cum within her, to make her swell with eggs.

Rick responded with a roar of his own, driving his hard and scaled cock into her folds, sliding within her damp valley with ease. She was gripping him with her pussy in a warm and wet embrace that simply wouldn't let go, and Rick loved it!

He rolled his hips forward, huffing with disbelief as the pleasure rippled within him even more. Then he began to thrust in earnest, sliding out of her pussy only to pound in a moment later, filling her beckoning depths with his shaft.

Sapphire's roars of delight soon filled the cavern, her huge and scaly form squirming beneath Rick's own. She seemed to love the feeling of Rick against her, so he lowered himself further onto her, his large stomach pressed against her back and his thrusts growing stronger and stronger, dislodging some of the treasure beneath them and sending it clanking down the hoard in small golden streams.

This was beyond any pleasure that he'd experienced before; this was a hedonistic ecstasy that was filling his every pore; his every desire. He hammered his huge cock into the dragoness again and again, her every moan music to his ears.

Sapphire only squirmed more, her proud form reduced to nothing but animal lust. She wriggled her own hips, doubling Rick's pleasure and making him roar in response, wild grins on both of their faces as their eyes glazed over with exultation.

Finally, the dragoness could take it no longer, a loud and echoing bellow escaping her lips as she climaxed, spilling herself along Rick's swollen mast.

The sensation of her fluids covering himself was enough to drive Rick over the edge as well, and he squeezes his eyes shut, a roar building in his throat as his balls clenched.

Then, with one last and passionate thrust, he came within Sapphire, a large gout of flame escaping his lips as he roared, bathing her with flame just as his cock bathed her pussy with cum.

It was the most intense orgasm of his life, bliss cascading over his form and making him roar with delight as the waves centered on two spaces along his back. With a loud tearing, a pair of wings broke free of his scales, spreading themselves wide over the pair of lusty dragons.

Sapphire roared with delight as well, her head craning back to cover him in tender, affectionate licks. Rick beamed at her, his wings beating in the air behind them, and returned her licks with some of his own.

The dragoness wriggled out from beneath him with a smile on her face, licking more attentively at the man-turned-dragon and purring with delight. Then she half-tackled him, wrapping her arms around him and licking him again and again.

Rick blushed beneath his scales, returning her embrace and falling onto the pile of treasure beneath them with amusement. It seemed that while Sapphire might have a reputation for a ferocious beast, she was also a devoted and loving mate.

He pressed his scaly snout to hers in as close of an approximation to a kiss as he could manage. She purred back, then rumbled faintly as she glanced down to her belly, her eyes widening.

Rick followed her gaze, curious to see what could startle her. His own eyes widened as he saw her stomach swelling, growing larger as though she was pregnant.

He hadn't realized it at the time, but some of the transformative magic had still lingered within Rick's body, the charms eager to please Sapphire's drive to mate—and to fill the inevitable conclusion of such an act.

The dragoness's stomach bulged with pregnancy and her eyelids fluttered with faint discomfort, a worried look in her golden gaze as she held out a taloned hand to Rick's cheek, beckoning him to stay with her.

Of course he responded with an affectionate lick of his own, caressing her stomach with his own talons. He'd have stayed with her even if he was a human; he wasn't the sort of person to impregnate a woman and abandon her.

Then Sapphire grunted, her eyes squeezing tightly shut. Rick hurriedly licked her worriedly, wondering what was happening to his new mate. She clutched him in her arms and howled as an egg crowned at her draconic pussy, its large and ovoid form slowly stretching her out as she began to birth it.

Rick's golden gaze filled with worry as he realized he had no idea what to do in this case. Still, the former burglar was nothing if not quick on the uptake. He hurriedly hugged Sapphire's body close to his own, his tail sweeping out a nest for the eggs.

The motion was just in time too, the first large egg slipping from her pussy and falling perfectly into its new home. Rick flinched at the sound of its hard landing; then he breathed a sigh of relief as he realized the egg wasn't so much as scratched.

It made sense: dragons were incredibly tough creatures; there was no reason for their eggs to be any less durable. He held his mate in his arms tightly as she followed the first egg with another two, forming a proper clutch for the pair to tend to.

Finally, when all of the eggs were laid, the pair of dragons slinked down to their nest, curling their wings around one another and holding each other close. Rick couldn't well go back to normal society in this form—not that he minded.

The burglar had come for treasure, but instead had found a family to call his own.
