Another story?! And so soon after the last one?! This is madness!
Nah, this is just me wanting to give a gift for his birthday. A belated gift but a gift nonetheless. Here we get to see Aaron using his scientific side to try and help Azar gain the ability through magic. Of course, Aaron must make Azar's body suitable for such magic in the best way the snake spirit knows how.

---

Azar had to wonder how timing worked when one was traveling from one world to another. Did it work like time zones, where you could travel for several hours only to find that your destination’s time said you were only an hour difference from where you started? Or did the universe just work on a single set time frame and it was just the creatures of these worlds that had come up with the concept of time zones when it was all just one set time. Perhaps he and other living beings like him that came up with the idea of “time” in general. The sun rose and fell with each passing day, but that was from the turning of the world. Not because there was some universal clock that determined when such things would happen. So what was the whole purpose of time?

Regardless of the philosophical implications of time, one fact remained true. Aaron was late.

The white dragon had been sent a message from the spirit a week ago, informing him that he was to meet the five-eyed spirit of mortality in the training fields outside St. Heimself. Azar would have liked to send a message back to the spirit asking what the occasion was for, but he had no way to send notes to another dimension unlike his serpentine friend. And now he was waiting in the fields, an hour having passed since the time Aaron was supposed to arrive.

Azar’s patience paid off when he started to feel a bit of static through the air. The air became dry and what appeared like a see-through bubble formed only a few feet away from the dragon. The ground near him began to rumble and bolts of electricity shot out from the bubble, thankfully missing the dragon. Without warning, the bubble opened up and spat out a violet liquid before disappearing, leaving a six-foot wide burnt crater in the earth. That was something Azar didn’t look forward to explaining later.
The violet puddle of ooze was still for a moment before it began to slosh around on its own. Aaron’s serpentine head raised up out of the liquid before it fully formed into his serpentine body. The violet serpent’s eyes looked around in different directions for a moment before all settling on Azar.

"Azar! I was looking all over for you!” he said, a wide grin appearing on his face as he floated up closer to eye level with the dragon.

“Looking all over for me? But you said to meet you right here,” Azar responded, tilting his head to the side in confusion.

“Well, yes, I did intend for us to meet here. But I haven’t quite got down appearing in a specific place when coming from my world to yours. I’ve been popping in and out of places all over St. Heimself for the last hour,” he said, his tail wiping across his forehead as if brushing away some imaginary sweat.

“All over?” Azar asked, before suddenly realizing what that meant. There were going to be several burnt craters throughout St. Heimself he was going to have to explain now. “Why didn’t you just fly from the first place you appeared to here?”

“For practice of course! I needed to work on the accuracy of my jumps. Plus, you can’t deny that my entrance through the portal is much grander than just floating on over,” Aaron said with a gleeful chuckle as he circled around Azar’s head.

Azar rolled his eyes, but smirked a bit at the serpent’s antics. Aaron could be mischievous, but he never caused any harm. “So what brings you to St. Heimself? Here for another visit and tour of the surrounding areas? Maybe travel out even farther this time? Your letter was rather unclear on what you wanted to do,” the dragon said, sitting down on his hind legs into the cool, soft grass.

“I would love to! But not right now. The purpose of this visit is for something far more interesting. I’m here to do a bit of a…test, if you will. I’ve got an idea on something and, you being a bit of a dragon of science must understand, I need to test my hypothesis,” Aaron said, floating back to Azar’s front, staying eye level as he explained. The serpent spirit’s tone got a bit more serious, but he did sound sincere and a bit eager to try out whatever it was he had in mind.

“And you wanted me here to watch you test this hypothesis?” Azar asked.
Aaron’s eyes all focused on Azar, his mischievous smile returning. “In a matter of speaking. In truth Azar, 'you' are the subject of my hypothesis.”

“Me? What could possibly make me a subject of research?” Azar asked, stepping back from Aaron just a bit. Not out of fear, but more out of instinct and wariness.

“A great many things actually. But today I want to test out trying to give you something you’ve never had before. The ability to use magic!” Aaron said, slithering through the air to the very tip of Azar’s snout. “Isn’t that exciting?!”

Azar looked at the five-eyed snake in confusion. “But Aaron, I already explained to you I can’t use magic. I wasn’t born with the connection to it like mages and other such magic users are,” he explained to his friend.

“Ah, but that’s just what I want to test! Maybe, just maybe, you do have that connection. You might have a connection that’s just so small, so weak, that you can’t use it. But if that connection were, let’s say…amplified, you could. If I’m right, then the potential for anyone who thought they were magic-less in your world could. Not that I think you or I should go around telling everyone that if I’m right. Who knows what effects that could have on your world. I just want to test my theory on you and you alone. As a good friend of mine I think you deserve it,” Aaron explained, grinning in confidence of his plan.

Azar put a front paw up to his chin, rubbing at it as he thought the idea over. It was, admittedly, a very clever idea and theory. As far as he knew, no one had ever researched on such an idea. There had been others, mad mages who had tried to force the ability to use magic into others, but that never worked and the results were…horrific. Azar knew Aaron would never try something so brash, and the idea itself was quite an interesting one. He imagined that, at worst, he just wouldn’t be able to use magic and remain the same as he had his whole life. And at best, he could gain abilities that could open an entire world of possibilities for him. In both his work for the Dragon Knights and his own technology work as well.

“Alright Aaron, we’ll give this a shot. Though I have to ask: how exactly are you going to amplify my connection to the magic of my world?”

“Simple! Since there’s no natural or artificial way to increase your magical connection on your world, we’re going to use a method from my world!” Aaron said excitedly, his body wiggling and slithering around in delight. The spirit was ecstatic that the white dragon was willing to help. “Do you remember how the people use magic on my world?” he asked, curious if the dragon knew what was coming.

Azar had to think hard for a moment, racking the recesses of his mind. “I…I think so? It’s been a while…hmm, it had to do with crystals didn’t it? They stored mana energy, or something like that?”

“Oh no! Well, you’re not wrong. But that is definitely not the method we’re using. I don’t like the use of the crystals. They’re time consuming to make, they don’t give good reserves, and they’re just not as fun. And your world doesn’t have the types of crystals necessary to make them anyways. No, we’re opting to use the more ‘efficient’ method.” Aaron told him as he floated closer, a smile coming across his face. He knew that Azar hadn’t come to the conclusion about what the spirit planned for him, but it was going to hit him at any moment now.

Azar looked absolutely confused before his expression turned to one of a dragon in thought as he tried to figure out this “other” method. It took a minute, but when he finally remembered the other method Aaron spoke of, Azar’s eyes went wide and he felt his heart sink in his chest. “Oh no.” he said, looking to Aaron.

“Oh yes,” Aaron responded, his mischievous smile now a wide grin. The serpent spirit’s body began to produce a gentle, violet glow as he channeled his powers. Several violet orbs appeared around Aaron, shimmering and shaking before taking the solid form of very real foods. All of them were various sweets he knew Azar secretly loved. Cupcakes, cheesecake, regular cake, pie, and more. Through his many conversations with the dragon, he found the Dragon Knight had quite the sweet tooth he always forced down. “Fat provides the best storage for mana Azar. If we make you big enough, that small spark of a magical connection could have more to run on. And you could use some more meat on your skinny hide anyways,” he said with a chuckle.

Before Aaron could begin his assault with food, however, Azar split. He whipped around and took off into the air, not wanting to submit to his fattening fate. Aaron may have meant well, but Azar had caught bits and pieces of how the serpent spirit treated those who he felt were “underfed.” Despite not being in active duty for the Dragon Knights, Azar had no intention of becoming a blob of scales and fat if he could help it.

“We’ve got a runner!” Aaron said excitedly, letting the food he had summoned phase out before zipping on after his friend. The serpent slithered quickly through the air, as gracefully and easily as an eel through water. And he was fast. Very, very fast. Azar was one of the fastest dragons in the Knights, yet when he looked back he could see Aaron rapidly approaching. The dragon tried maneuvering through several of the obstacles out on the training grounds, ducking around and swooping through hoops and blocks that were suspended in the air by rotors of Azar’s own design. But the white dragon’s panic of escaping his pursuer made him temporarily forget that Aaron was a spirit. While Azar’s maneuvers would most likely have thrown or put good distance between himself and another dragon, Aaron just phased through the obstacles and kept speeding up.

When Azar looked back again and spotted Aaron even closer, he mentally cursed at himself for forgetting such a simple fact. He began to formulate a new plan, but when he blinked and looked back at Aaron, the serpent was gone! Azar quickly looked around to see if Aaron had dropped down, or gone higher. But the last place he looked was right in front of him, and when he did he had to turn his wings so the wide wing membranes could catch the air and he skidded to a stop. Aaron was already waiting up ahead, having teleported himself further ahead.

Azar managed to stop himself just a few feet away from the serpent. “You’re cheating!” he said, trying to turn away and dash off again. Aaron caught on to the attempt this time, and once again his body began to glow. Right before Azar took off, he felt something coil around his waist and pull him in, where more coils wrapped around him. Aaron had increased his own size just enough that he could coil around the dragon and keep him restrained until Azar wouldn’t need to be restrained any further. “Now, now, I can’t have my test subjects running off on me can I?” he said with another chuckle as he floated Azar back down to the ground.

The white dragon squirmed and struggled, but Aaron’s grip on him was strong. “Come on Azar, I’ve got all your favorite foods! This will be fun, I promise you’ll enjoy it,” he said to try and ease his friend a little. “Besides, this is all for science. You’ve got to appreciate that.”

“Aaron, I don’t want to-“

Azar was cut off as Aaron phased in several sweet pastries into the dragons open maw. He knew if he waited, Azar would probably just keep his maw shut and it’d be harder to feed him then. “Aaron, I really can’t-“

Aaron cut him off again, not meaning to this time, with another mawful of food. Now the process had begun. Every time Azar would finish a helping and open his mouth to protest or to take a breath, the spirit would give his friend a few seconds before phasing more food in. The sweets, and soon deliciously cooked meats, were altered slightly for the purposes of the experiment. They contained a high number of calories that Aaron managed to mix in there through magic of his own. This would help Azar gain fat quick during the feeding instead of having to wait a week or so after stuffing the dragon for the food to digest and turn into fat naturally. Evidence of Aaron’s specially modified food started to show after fifteen minutes of stuffing his friend. Azar’s thin, toned stomach was now bulging outwards almost a foot. And every few minutes it would gain a few more inches.

Aaron stayed coiled around his friend, however. Despite starting to plump him up, he knew Azar was strong enough to carry quite a lot of weight while flying. Even if the weight was his own gut. If he freed him now, he’d just have to chase his friend down again. And that would burn precious calories that needed to be used for magic! The five-eyed serpent kept a close watch on Azar’s size, watching for when he would hit the right size for the experiment.

Half an hour had passed and Azar was still being fed. His resistance had faltered, now knowing he couldn’t escape Aaron’s coils or the fact that he was going to be much more sluggish and slow with his stuffed belly. The white dragon’s silvery stomach pushed out past his knees, the armored plates along his underside starting to separate to accommodate for the growing mass beneath them. He groaned a bit at both seeing his body turned into a fat version of his normal self, and from the strain of so much food and weight piling on himself in such a short time frame.

Aaron quickly caught on to his friend’s discomfort and, being an expert in feeding others to their limits, knew just how to help. Violet tendrils extended out from Aaron, making their way towards the dragon’s growing middle. The ends of the tendrils took the shape of hands and they began to work their way along Azar’s growing expanse, rubbing and kneading gently to ease any pain. And it worked wonderfully. Soon Azar’s groaning turned to pleased thrumming, a smile finally coming across his face. “See, it’s not so bad,” Aaron told him as he kept the fattening dragon full and happy.

More time had passed and Azar was reaching the point of immobility. His belly went well beyond the ends of where his paws could reach if he were on all fours, so there was no way his wings could lift such bulk. Aaron finally uncoiled from the white dragon, leaving him sitting on his hind legs in the cool grass. The serpent returned to his normal size, but the food kept coming and the tendrils kept massaging his friend. “Hehe, maybe you can be the Dragon Knights’ representative blimp in the next parade,” Aaron teased the tubby drake.

“Sh-shush you,” Azar managed to respond, his face blushing a little at his predicament. His cheeks had become rounded with fat, his arms thick and wobbling as they laid rather uselessly on the top of his stomach. His hips and legs were wide, helping keep him planted on the ground. And his tail sat there, a fattened sausage laying next to the former warrior instead of being the powerful appendage it was. His body had gone from the embodiment of the fearsome dragons of the sky, to something more like a combination between a marshmallow and a pillow. Azar could only sit there and keep eating, both because there was nothing else he could do, and after so long of being force fed he was finally enjoying the food.

Aaron floated around the bloated dragon, his eyes once again looking in all different directions as they summed up the progress he had made in fattening Azar. Finally, when his eyes refocused, the spirit nodded and slithered up to Azar’s head to get into the dragon’s line of vision. By now, most of Azar’s vision was taken up by his huge belly, so Aaron floated just above the dragon’s snout. “Good news! I think you’re sufficient size to test this hypothesis!” Aaron stated excitedly.

“Hip hip *urp* hooray,” Azar said half-heartedly and a bit sarcastically, hardly having the energy or strength left to lift his arm up for a celebratory paw-pump into the air.

“Yep! Now we just have to channel that spark of yours to the rest of your big self,” Aaron said as he materialized two arms for himself, reaching down and putting them on Azar’s stomach. “Oh wow, you really are soft!” he said with a smile before looking up and seeing Azar looking unamused.

“Right…back to magic channeling!” he quickly said.

Aaron started concentrating, closing all but his center eye as he began to search and reach for the spark of magical connection he believed was in his dragon friend. The glow once again appeared around the serpent as he searched, and Azar could swear he felt a new kind of warmness form within himself. Was Aaron exploring through the dragon’s very soul?

All was quiet for the next ten minutes, except for the rumbling of the dragon’s stomach, as Aaron kept at his work. Finally, Aaron let out a deep, held in breath and opened his eyes.

“Huh, I guess my hypothesis was wrong. There wasn’t anything there to channel into your body. Oh well!” Aaron said, his materialized arms disappearing and the serpent floating up to coil on top of Azar’s belly, just within Azar’s line of sight.

“Oh well? Oh well?! What do you mean ‘oh well’?!” Azar said, now frustrated that what he had been put through amounted to nothing.

“Like I said, my hypothesis was wrong. Or, more accurately, I’ll have to accept the null hypothesis that fat does not amplify a non-magic user’s magical abilities. Turns out non-magic users in your world either don’t have a small connection to magic that has yet to be realized, or using my world’s methods doesn’t amplify it. I’ve still learned much from this experiment, and having to accept the null hypothesis means that there’s room for more experiments in the future! Isn’t that exciting?” he asked, his grin returning again.

Azar gave Aaron an unamused, annoyed look before he was interrupted by another belch. Afterwards, he sighed and tried to relax. At least Aaron’s magical tendrils were still rubbing along his belly, so there was one good thing that came out of this. “Alright, you did your research and learned what you, and I, needed to. Now can you please do something to return me back to normal?” he asked his friend.

The five-eyed serpent through for a moment before his tail flicked up. “Oh, yes of course! I wouldn’t let you down.” Aaron said, winking at Azar before summoning his magic once more. This time, a rather large orb of light appeared next to Azar. As it shimmered and morphed to take shape, Azar covered his eyes as it flashed into some sort of object. “What are you doing?” he asked before looking to see what Aaron had summoned.
Sitting next to the fattened drake was a very large treadmill.

“Wh-what is *urp* this?!” Azar asked, looking back at Aaron, who seemed to be getting very comfy on top of the dragon’s belly.

“It’s a treadmill. I know you’ve invented one and know how it works. Once you lose some of that weight, you can start running on it to lose the rest much faster,” Aaron explained, looking quite satisfied with himself.

“Is this a joke? Why don’t you just take all the fat away as easily as you put it on me? You’re the one with magic!” Azar said, getting frustrated once more and the red blush reappearing on his face.

“Well, the thing is, that’s not really how I work Azar. All that fat is extra nourishment for you, and I can only provide nourishment, not take it away. Getting rid of that fat you have is against what I do. But, if it’s any consolation, I think you hold all that weight well. It’ll be a shame when you work it off. But, I think when your fellow Dragon Knights come out to these training fields tomorrow, they’ll be more than happy to get you on that treadmill and lose those extra pounds,” Aaron assured him. Though he himself was going to be sad to see Azar lose all that healthy weight. Maybe he could refatten Azar on his next visit? After all, it wasn’t that hard to do. For now, he could at least enjoy the wonderful bed Azar made, snuggling into its softness and getting ready for a nap.

Azar’s blush deepened and he laid his head down on his soft chest and belly. “Great,” he said with more sarcasm. Now he was going to have something even bigger to explain than the burnt crater in the ground. He certainly wasn’t looking forward to that conversation.
