Little hatchday present for LEthias. We went halfsies on the pic, but the story is my gift to him.

In this story, Ceylon meets up with Lethias in the capitol city, only to feed him an exponential growth potion while she takes advantage of his particularly sexual growth patterns!


A Potion of Exponential Growth

She leaned down so that her eyes were level with the side of the vial, her beak nearly touching the thin glass as she poured a red fluid into it. She kept her eyes trained to catch any variance in the fluid as she reached for a second vial, putting the first in its upright stand. The second vial was full of a purplish blue liquid, which she poured into the larger vial. Once the two fluids mixed, the entire concoction turned a deep purple-red color, like a finely aged wine.

"I'm getting close, but I'm not there yet. Need some of that as well." She shook the beaker and turned to her shelves to take another tiny vial of fluid, this one an opaque milky white color. She spun back around and brought her face up close to the first beaker again and poured just a few drops into it, the opaque solution disappearing into the wine-like fluid. "Perfect. Now to add some flavor, dilute it a bit, and infuse it. Perfect." She grabbed a pitcher of grape and cherry juice, pouring it in the vial until it was nearly full.

Content with the blend, she put a stopper on the vial and shook it gently, rocking it back and forth, twirling it up and down as she closed her eyes and focused on the flow of magic from her hands. She felt a familiar tingling trailing through her chest, down her arm, and into her wrist as a turquoise mist emanated from her palm, immediately clinging to the side of the vial before turning into condensation and apparently disappearing.

"Infused. Awesome." She gave the vial another shake as she looked around her work station. It was kind of a mess, but she was running behind. To her, still no reason to leave an unkempt work environment. The last thing she needed was to return and not have it ready for it. Naturally, she put the vial of fluid in her pouch near the door as she scuttled back and forth across the room, putting beakers where they go, double checking the labels, and ensuring that every book and every piece of equipment was squared off. It only took her a matter of minutes to tidy up her mess, but it felt like she'd done spring cleaning. It always felt like an accomplishment.

She laid her talons on her hips, smiling gently as she finally turned to leave. She grabbed the bag, slung it over her shoulder, and was sure to close the door behind her. She already had her suit folded and pressed neat in her bag, she didn't plan on wearing it as she went down the mountain; no, that wouldn't do, not if she planned to fly.

Ceylon the gryphoness left her lab and walked through their visitors room, where her mate was coiled up and soaking in the sun's rays through the large open windows in the side of their home, expertly inlaid in the side of a cliff for the morning sun to shine on. Another area was for the evening. Ceylon knew she could leave without her mate noticing or caring - they were both quite autonomous - but she had to say her goodbyes for the day.

The gryphoness walked up to her mate and stepped next to her, closest to where the naga's massive snake head was resting on one of her coils. "I'll see you around, Leera."

Leera opened one eye and looked up at Ceylon, a smile on her lips as her tongue flickered out. She shifted her whole body, gently edging her head towards her gryphoness mate for a nuzzle. The two couldn't really kiss in the traditional sense, so the naga flicked her tongue and tickled at Ceylon's neck feathers as the gryphon returned the affection by nuzzling up against the heat pits that lined the naga's lips. "When will you be back?" She asked as she laid her head back down on her coil to absorb more of the morning sun's rays.

"I don't intend to be away for too long. I'm meeting Lethias in town, and we're coming back up the mountain. No idea how long that will take. I suppose it depends on what his plans are, and if he wishes to do anything in town." Ceylon gave a nod and smiled, her black and white feathers standing on end around her chest and neck. The tips were a rusty color, as was typical of this season.

"Well, I don't want to keep you. I'm still basking, likely will be when you return. Have a good day, sweetie!" She flicked her tongue one last time before closing her eyes and nuzzling back in between two coils.

Ceylon nodded in agreement and quickly darted out across the room to emerge on the balcony, overlooking the valley.

They, along with ten others, lived in the Cradle of Dalon, a valley int he tallest mountain range of all Dalon, so tall that few others could climb that high, even those with wings would be unable to float that high without the aid of additional magic buoys. It was the perfect place for them all to live away from the common folk, where they could do their research and experimentation without the prying eyes of the governments or clergy.

Up here, they could avoid the hustle and bustle of city or farm life, living only on their own discoveries and knowledge. It was certainly ideal, but it did have its drawbacks, namely the loneliness. If Ceylon wanted to converse with anyone not of their remote team, she would have to use what transformation magics she had accumulated and perfected to grow a pair of wings, then use her other elemental magics to give her the lift needed to escape over the mountaintops so she could glide down to the city that was to the east of the cradle they called their home. Such a transformation required a lot of energy, but that's why she expected to spend some time in town with her friend before returning.

For now, she wore no clothes for fear of tearing them. That's why her suit was neatly packed in her bag. She opened up the bag to make sure she had everything she wanted, and once she went through the checklist, she closed her eyes and leaned over the balcony, concentrating her magics on the flesh and bone of her back. It took a few minutes, but she felt her skin shift and her feathers realign as two appendages expanded from either shoulder blade. First the bone shot out, dry as could be, only to have the flesh extending up around the appendage and engorging itself, connecting tissue to tendon and bone. After that, the epidermis slid up the outside of the muscle like a foreskin, closing up and sealing at the tip. Finally, once all the tissues were formed and connected, the long, bread black and white feathers shot out and immediately formed the majestic wings she was known for.

Ceylon kept her newly formed wings spread out wide, angling them in multiple directions and bending them one after another to test strength and tendon adherence. After a few idle flaps, she was convinced the transformation had been successful.

She gave one final look over her shoulder and through the twin doors to the common room where Leera was resting before hopping up onto the rounded bannister that doubled as a perch when she was in her quadruped form. Her talons pierced the soft wood for balance before she kicked off, dicing over the steep decline of the mountainside, careful to not let any of the trees or rocky outcroppings catch her off guard. Her eyes were keen, as any gryphon's should be, so that was not a problem.

Travelling down the side of a mountain was easy, and didn't take her long at all to reach the foot of the mountains, where the cellitoke woods splayed out across this quadrant of the valley, the other half being a wide open field. The tallest tree of that area - which stood out as at least ten times the height of the forest - was where Ilorek and Valencia lived. The tree was so tall, and their home in such a high area of it that they were almost as high, altitude wise, as Ceylon and Leera were in the side of the mountain.

All of that whizzed by below and around her as her wings picked up every last bit of the air currents that blew through the valley, guiding her out to the large open field, then over the side of the cliff that dropped seven Km straight down into the largest lake in the world. If she flew over this lake, she could glide her way east around the coast before eventually reaching the capitol city of Klyneth. That's where she was to meet up with Lethias.

The only exhausting part about getting down from the mountain was her transformation and the large amount of energy needed to grow the wings, the actual trip east was as easy as opening her wings and floating until she reached her destination. It took about half an hour or so to glide from her home in the mountain side through the valley, over the lake, and to the outer area of the city.

Once she finally landed in the thick forests to the north of the city itself, she immediately folded up her wings on her back and focused heavily on re-absorbing the flesh and feathers into her back, the mass to be redistributed across her body so that nobody knew she was able to create and remove her wings at will. Didn't need people learning that was even possible.

As soon as her extra limbs were gone and no traces were left, she opened her bag and got out her suit. A long pair of straightened pants, a thick white undershirt, a tie, and a gray pinstriped vest. Very professional. The plumage on her chest pressed out against the undershirt enough that she looked barrel chested, powerful, like a drake. She loved that.

She wore no shoes. Few avians felt the need for that; she had powerful, ebony-fleshed talons, and shoes would just restrict that. Content, she quickly hopped over the underbrush and around the felled logs before finally reaching the Urto trade route, so she could make her way south to town.

The trip from her landing point into town took about as long as the flight down from the mountain, and by the look of the sun she was right on time. She was to meet Lethias in the middle of the city near the fountain and the six points intersection at a world renowned cafe. She told him that was where to find him because it was such a significant landmark that even a child could instruct him on how to get there once he got to town. He wasn't familiar to the area, but it was a pretty popular city, and there were ways to help him out. I

Ceylon had taken extra measures to put a bit of a reserve at her bank under Lethias's name and likeness, so that if he needed some extra funds, he would be taken care of while in town in the event he made it to the six points intersection first.

Despite her many years of living here and in the vicinity, Ceylon always had to stop and admire the architecture of the buildings of Klyneth. The city wasn't known for just one style, but an amalgamation of different styles from all over the world. Some buildings were of clay and had an angular look like the homes from the north, others were flat and made of planks of wood, some were made of stone. Some were angular and hard cut, while others were soft and curved. It was a beautiful blend, and Ceylon had witnessed the erection of the town one building at a time, helping to influence the overall look so that the colors and shapes blended well and looked good together. It was a beautiful city.

She padded her way though the walkways past the various people of all races and species. Equines, Avians, felines, canines, and even a few saurossins milled around her, walking in groups up and down the marble walkways that lined the paved streets. She could see the cafe up ahead, so she quickened her pace until she finally reached the white metal fence that lined the outer patio of the establishment. It was one of the six buildings that met nearest the intersection, so it would be easy to see from any angle.

The gryphoness peeked into the cafe from outside the metal fence, glancing through the patrons to see if Lethias had arrived yet. She did see a few dragons, but no Lethias. Her friend was red-scaled with blue stripes up his chest and overlaid sets of hard plates on his elbows and knees. Perhaps not the flashiest of saurossins, but easy to pick out of a crowd. With that in mind, he was nowhere to be found.

Ceylon bolstered a smug sense of superiority, knowing she'd arrived first despite being late and getting caught up with some petty little nitpicks about her lab. Even running late, she arrived before her friend. Not surprising, Lethias was reliable but had terrible time management skills, for all she knew he was still a dozen kilometers outside of town, having misjudged just how long it'd take to fly to Kylneth from the border of the northern nation in which he hailed.

She couldn't be too hard on him, though; that was a very long trip to take, and lots could happen between his home and hers to slow him down. She was lucky enough to have no obstacles between her and their meeting location, so of course she was there first. The gryphoness had to remind herself of her privilege before finally deciding to go into the cafe.

There was a large set of arches that she had to walk through, and a red carpet that took her to the barista that seated her outside on the patio - her normal spot. She ordered herself a white chocolate beverage with dried fruit shavings on the top to keep herself occupied while she waited for her guest. She was careful to ensure her suit was well presented, only the faintest hint of the rusty feather tips poking out the collar and bits of feline hair out the bottom of the cuffs of the pants. She still couldn't avoid her tail, so she happily stuck it out the back of the chair to wrap its length around all four of the legs, anchoring her, just in case.

It was another half hour before Lethias showed up. He introduced himself by flying high over the many buildings of Klyneth, his winged form casting a shadow that would streak across the city only to have him fly around and do the same thing a dozen times or more before he realized where he was supposed to go. Once he got his bearings, he swooped down into a dive, aiming directly at the fountain in the middle of the intersection. He flared his wings out and spun in a tight arc before landing heavily on the marble sidewalk with a powerful thud that Ceylon could feel in her talons, many meters away. Once he stuck the landing, he pufed out his chest and folded his wings on his back, chin up as he scanned the patrons of the cafe.

Typical. Had to show off on his entrance. He was certainly a powerful drake, but his pride often interfered with function, at least when it came to showing off his body and power.

"I'm over here!" Ceylon waved to him, urging him to join her at the cafe while also motioning that he should enter through the arch way first, which was comical because he was nearly as large as the arch, so he had to duck to get through.

Once he instructed the barista that he was to join up with Ceylon, they happily took him to the patio to join her. As he was seated, they asked to take his order.

"Oh, I'd like a chicken, bean, and rice wrap, please. Lots of hot sauce, please." He offered a polite nod, followed by a sly wink to Ceylon as he asked for the hot sauce. "I like it spicy." He reassured her.

"I'm aware." Ceylon smiled and lifted her mug to him, bringing it up to her beak so she could dart her tongue in it. "So how was your trip?"

"Pretty long in the wing, very tiring. Harder to find this place than I expected when you told me how easy Klyneth was to navigate." He smiled a toothy grin as he nodded, stretching out his wing a bit and letting it droop to accentuate how fatigued he was.

"Well, Did you askf or directions?" Ceylon inquired, taking another sip.

"No need. I had my directions. I'd find it eventually. Besides, I have all week, what's a few extra minutes? So what did you have planned for the week?" Normally, the two would have been in correspondence to work out the details of their visit, but Ceylon was very busy with her work and Lethias was gaining new clients, so the courier system just wasn't fast enough to share the details in time, so they both decided to just 'wing it', a turn of phrase that incited Lethias to make all sorts of flight jokes that Ceylon preferred to ignore.

"Well, I know we were planning on just playing it by ear, but I have a few things lined up. For today, since you're likely exhausted from your flight in, I was just gonna invite you to a meal, then take you back to my home and introduce you to the group I've been researching with. I'd love for you to meet Leera, especially, but I think you'd also like the others. Today is just relaxing with friends."

Lethias nodded and flicked one of his ear frills, thinking about that. "Sounds good. Got any other plans for the rest of the week?"

Ceylon shrugged her shoulders as she took another sip. "I have a few ideas, surprises mostly. Many of my plans are loose because it depends on how well you take to each of my friends. Ilorek would love to show you some chemistry, Olfrin would probably love to use some potions to give you gills and take you deep into the lake, or Talba would probably love to show you around the castle. Whatever works for you. Like I said, no solid plans, lots of options, we can wing it."

"Wing it?" Lethias cackled, "As in-"

Ceylon stopped him mid-sentence. "No wing puns. Not today, mmkay?"

"Awwwwr, why not?" Lethias slumped and made a mock, exaggerated frown.

"You're not as punny as you think you are!" Ceylon grinned and winked at him.

"Hmph. I am exactly as punny as I think I am, thank you very much!" he lifted his snout in faux indignance as he huffed at her, only to be met by the waiter with his chicken wrap. As soon as it was in front of him - dragon sized, of course - he gave a sly, sideways grin to Ceylon. "Hey, you're not gonna be offended if I eat this, are you? Being part chicken, and all."

Ceylon's grin disappeared from her beak as she stared at him, stone-faced. "I'm not a chicken, thank you very much."

"Alright then, kitty." Lethias joked as he took a big bite of his wrap.

Ceylon's face remained as motionless as stone. "Not a Kitty."

"Meow?"

She couldn't hold back any longer, instead bursting out in laughter at his speciest jokes. "Oh you, shut up and finish, we gotta get back to the valley so I can show you around, and it's best to do it quick because the air is thin and you'll need help flying that high."

Lethias licked his lips and swallowed. "I doubt I'll need your help flying, I have pretty good wings." Again, he extended his wing out to show how broad it was, the tip of it poking out over the side of the metal fence, nearly hitting one of the passerby, only to have him quickly retract it and apologize. "See? Thermals will get me high enough, but thanks!"

Once again, Ceylon shrugged. "We'll see. Anyway, finish up, it's time to go."

Once the two had finished enjoying their meal, they both walked to the outskirts of town before taking flight. This confused Lethias, who didn't understand the significance, at least not at first.

"Why can't we just fly? I can carry you, or can't you use your magic to fly? Telekinesis, right?"

"Let me show you." Ceylon slowly began stripping her clothes off to fold them and put them in her bag. As she did so, folding the fabric into neat little squares, Lethias gawked at her, looking up and down her body. She noticed, and quickly dispelled any lewd thoughts he may have had. "Not like that, ya horny drake. No, watch."

She stepped out into a clearing with her pack still over her shoulder as the flesh and bones of her back twisted and distended, slowly stretching and expanding until they'd formed the shape of two massive, featherless wings. The muscle definition was clear, and the sinews twitched as though they were adjusting feathers as the actual feathers grew rapidly from nothing. Once they were fully formed and spread out, she looked over her wing shoulder to smirk at Lethias, winking at him as she showed off.

The dragon was awestruck. He'd seen all sorts of magic, but never had he seen a limb grown from nothing like that. His jaw was slack and his eyes were wide. "I didn't even know that was possible!" He whispered.

Ceylon was still looking over her shoulder. "Well, how did you think I was going to fly?"

"I-I didn't really think about it. Telekinesis? Maybe I'd fly you up there on my back?"

She casually folded her wings up on her back, the shoulders high above her head and the feather tips nearly touching the ground. "Well, no. Transformation magic...I created it. It's a peculiar blend of healing magic, physical magic, and some alchemy all in one. It's very complicated, but I have mastered it. I'm teaching it to the others over time; they're picking it up, but they're slower than I am."

"Can you teach me?" Lethias asked, leaning in to press his hands against her wing to see if it was real or just an illusion.

"I can teach you, but I doubt you have the skill to pick it up in a week. It takes a lot of energy and intimate knowledge of biology. You have to concentrate on three different schools of magic at once, all while having an intimate knowledge of musculature, bones, the respiratory and circulatory system, and the way it all interacts with your natural body without interrupting your basic functions. Take too much blood from the rest of you too fast, and you pass out. Fail to thread the nervous system's many tendrils throughout as the flesh is being conceived, and you end up with two limp wastes of tissue. So many things can go wrong."

"Wait, how did you learn all this?" Lethias asked, a crackling hint of annoyance in his voice at the subtle implication that he may not have been able to handle a type of magic.

"It was one of the first things I learned. This isn't my natural body, you know. I was born quadruped. The only way I could be taken seriously was to walk on two legs, but the body shape was all wrong, so I deliberately broke my own limbs and rearranged them, applying healing magics to the joints as I did so. It kind of came naturally to me, and now I can change my form at will; still takes a lot of energy, though. Once we get up to the valley - The Cradle of Dalon, as we like to call it - I likely won't have a lot of energy left to do anything but relax and enjoy a meal or a snack or something." She ruffled her feathers and spread her wings again, preparing to take off. "Now, keep up if you can!" With that, she kicked off the ground and flapped her wings, the lift barely taking her above the treetops, where she swooped around and kept herself afloat as she waited for Lethias.

He didn't take long to follow. With one quick leap and a spin in the air, his wings caught a slight breeze and he was airborne!

The two of them flew low over the vast forests around Klyneth for a while before finally heading out towards lake Safra - the largest freshwater lake in all of Dalon surrounded by the largest mountain range and the largest forest (There was a reason Klyneth was a cultural and historical focal point of Dalon). Neither could speak, for the wind whipping past their ears ensured that all they would be able to hear of one another was the whooshing of the wind over their ears.

They had to keep to the south of the lake, for the valley was in that area of the mountain range, in the branch that curled around the south of the lake, reaching out almost to Klyneth itself. Wrapped around the edge of the lake was a massive cliff about seven Kilometers high - about twice as high as most could fly - with a pair of waterfalls cascading over the clifs and creating a hazy mist and a rainbow in their wake. That's where they were heading.

In a bit of a showy display, Ceylon dove and spun before quickly flying up the side of the cliff, using magic to boost a cushion up under her wings for leverage - without it there'd be no way to fly that high, as the air was too thin that high in the mountains.

Lethias tried to go up that high as well, but as hard as he flapped and tried to emulate her moves, he just couldn't gain enough altitude. Desperate, he slammed himself into the cliff face and dug his claws into the rock, trying to scale it that way, only to have the moisture and bits of moss on the rocks create a surface that was too slippery for him to grip. Time and time again, he fell to the lake below, opening his wings after doing a flip in the air and regaining his composure.

Ceylon watched for a while to prove a point before swooping back down to help him out, conjuring another hot bubble of air under his wings that shot him up high in the sky, almost like he was falling in reverse. Once he finally hit the edge of the cliff at the northern end of the valley, he tumbled head over tail before regaining his composure to glide gracefully over the plains, landing next to the river that split the valley in half. Ceylon joined him and folded her wings back up, once again absorbing them into her back as she padded her way along the tall grass towards him.

"Welcome to my home!" She raised both hands to either side of the valley. Behind them, the world opened up over the cliff, showing them all of Lake Safra, all the way down to Klynet, the great Safraldian wood, the plains, and everything. Ceylon's keen eyes could even see to the edge of the horizon, where she could see the shore of the ocean. Lethias likely couldn't see that.

She continued to explain. "WE call this river, the one that slices right through the center of the valley, the 'jet stream'; On this side, we have the bed of the cradle, also known as the high plains. The other side, the Cellitoke wood. You'll see it's got an interesting color, as the bark is blue and the leaves are all manner of shades between green and blue. At night, the flowers open up, and it is a beautiful cornucopia of spring and summer colors, with ferns and flowers of red, yellow, and orange." She then pointed to the tallest tree, "And that's where Ilorek and Valencia live, high in the grand Cellitoke. Ten times taller than any other tree in the world."

Lethias seemed impressed at the lay of the land, but he was focusing a bit more on the deep, labored breaths he had to take in the thin mountain air. "Is this normal?" he asked.

"Well, people really aren't supposed to be this high in the mountains. It's not good for the athletic types. You'll eventually get used to it, and you'll be stronger for it. We all are." She patted him on the shoulder, then continued her visual tour of her valley. "If you follow the river upstream, we'll eventually see the Lake that Olfrin lives in. That's where he'd take you on a tour of its depths, should you be interested in having a bit of transformation magic done on you for gills."

His eyes lit up. "Yes please! I love swimming! It's one of my favorite things!"

"Hm, I wouldn't have guessed, actually. You strike me as more of a flyer."

"After that performance coming up here? Hardly!"

"You don't need to feel bad about that. We chose to do our research up here for a reason. That reason was that the mountains are too steep for most to climb, and the valley is too high in the mountains for even the strongest winged creatures to reach without just the right magical help. It was done that way on purpose." she paused to let Lethias gather his thoughts before continuing. "Anyway, on the other side of the plains, in the foothills of the western range, is the castle of Talba and Vaulix. They mostly keep to themselves, but love to travel, so they might not even be here right now. I honestly don't know. Beyond the Cellitoke wood is my home, where I live with Leera in the mountain itself. Carved out our cave and made a bunch of perches and balconies so we were both happy. Also found a pretty interesting cave system that we like to explore together that actually leads back down to sea level."

Lethias's eyes were wide as he continued to look around. His vision wasn't as good as Ceylon's, so he couldn't see the castle or the home in the mountain, so instead he just smiled and nodded. "So, you ten live here, alone, where nobody else can get to you? And you basically own all this land, the entire mountain range?"

"Twelve of us, and yes. Leera and I live in the mountain, Ilorek and Valencia live in the Grand Cellitoke, Talba and Vaulix live in High Plains Castle, Luero and Olfrin live in Top Secret Lake (We just call it that, we haven't come up with an official name yet), Keran lives in a cabin next to that lake, Yelena and Sanfrit have a home in the Southwood Valley, and Satsierra...doesn't really have a defined location. Between he all of us, we own this area, and I don't think anyone would want to take it, even if they could. We're using this as our home base for our research."

"You know, I've known you all these years, and you haven't told me what you're researching." Lethias mused as he rubbed his chin.

"Well, it's just magic stuff. Nothing in particular. Trying to find out how it works, how to better manipulate it, and how to use that to our advantage. I even have a sample of something I'm working on, if you wanna try it." She reached into her bag and pulled out the vial of fluid she'd been working on prior to meeting him. It still looked semi-clear, like a wine.

"Odd, I thought you didn't drink." He commented as he took it. "And really, up this high in the mountains, I doubt it'll be good. Not safe to drink and fly, you know!" He smiled as he used his claw to pop the cork, giving it a sniff. "It does smell good. What is it?"

Ceylon chuckled a bit. "Oh, it's not wine, it's a potion. One I specifically made just for you today on your hatch-day! It's a blend of various magics and liquids, meant to give you a sizeable boost in libido."

Lethias cocked his head to the side and lifted one ear frill. "Oh, are you trying to take advantage of me? Well, I guess it IS my hatchday, so I suppose it's alright! All you had to do was ask, you know." With that, he threw his head back and drank the potion in one gulp.

Ceylon tried to stop him, but he swallowed before she got a chance. "Hey! I wanted some of that, too!" She reprimanded him. "But I guess it might be fun, either way." She took out her pad and pencil from her bag and started writing things down.

"Tastes good. Like a wine without the alcohol. Except, it's almost like it's a berry-grape wine. And hey, what are you writing there?" he tried to peek over the edge of her notebook, but she pulled it away.

"Just notes. Gotta see how the potion effects you. It's still a work in progress, so I don't know quite how effective it is, but I do think you'll like its effects, if it works well." She nodded and put down some more notes before returning the book to her bag and happily taking him for a leisurely stroll up stream by the riverbed.

Lethias seemed disappointed at first. "So what exactly is going to happen to me with this potion? I'm not feeling anything at all."

"Well, if it goes well, certain parts will grow to extreme proportions."

"Oh? What parts?" Lethias seemed genuinely interested, but wanted to know more.

"All sorts of parts. You'll see. Trust me, I wouldn't do this without proper precautions. Besides, it will be a lot of fun for both of us." She gave a devious wink as she continued to guide him up the river bed. She was deliberately unclear with him, even though she knew, deep down inside, that it drove him a little mad. It was almost her way of teaching him a lesson for drinking the entirety of the potion without waiting to find out what was in it or what it did. She could tell just by looking at him that he was doing his best to not grab her and shake the answers out of her petite frame.

It didn't take much longer for the first signs of the potion working to crop up. As they walked, Lethias started idly rubbing his massive red talons against his inner thighs and walking funny. He was trying to stop himself from rubbing at the slit between his legs, but it was clear that's what he wanted to do.

Ceylon cocked her head to the side and got a look, making a joke. "What's the matter, can't contain yourself?" She asked with a coy grin. As she watched, she saw his shoulder muscles twitch a little, his wings shuddering. The potion was clearly taking effect, slowly but surely.

"Well, no. I have this overwhelming desire to bend you over right now and mount you."

She grinned and winked at him. "Well, I can't say I'd put up much of a fight, especially not considering just how endowed I'm sure you're about to be."

Lethias should have picked up on the subtle clues in her comment, but his mind switched to 'horny drake' mode as soon as she said she wouldn't put up a fight. His hand was still resting on his groin, so he peeled back the slit that contained his member, exposing the pointed tip, using his fingers to rub at the end of it.

Ceylon, however, was trying her best to keep from looking. She knew what was about to happen, she knew what she'd put in the potion, and she wanted to wait until Lethias was comfortable to expose herself and the next part of her plan. It was his hatch day, after all.

Despite his particularly enthusiastic hand, he was actually holding himself together quite well. He wasn't jumping her yet, and he wasn't even at full mast. He kept quiet as he walked, fondling himself idly as they continued up the riverbank.

Still curious and interested in documenting the process, Ceylon got her book back out and took notes as his cock slowly emerged, growing larger with each throbbing heartbeat. At first, it was normal sized, but the more he fondled, the bigger it got, even beyond normal porportions. Perfect. Matching his bulging cock came both gonads, forming spherical growths between his legs below the underside of his shaft, bulging out the scales there to form a temporary scrotum. Again, perfect. Now that he was fully aroused, it was time to make her move.

She tossed her book back in her bag, but missed and dropped it on the ground instead. She took special care to slowly bend over, legs straight and doubling over at the hip with her tail raised high int he air, rump aimed at Lethias. She didn't directly give him an invitation, but it was about as clear as it could be. Her vulva were hidden mostly by fur, but an ebony slit of glistening flesh could be seen poking out under her mound, and that should have been enough.

Lethias groaned a bit as he puffed out his chest, hand still squeezing at the base of his cock tip. He grabbed a hold at the base of Ceylon's tail and held her in place. He didn't immediately press himself against her, instead taking a moment to massage her rump with his thumb as he waited for further approval.

There was no intention of keeping him from her flesh, so she looked over her shoulder and winked with a nod, a grin peeling up either side of her beak as she leaned back into him, wagging her hips a bit as she pressed the underside of her tail against the tip of his cock.

A deep rumbling growl escaped his throat as he positioned himself with his legs spread a bit - his legs were longer than Ceylon's and he didn't want to force it to aim down - as he pressed his cock against her rump, using her shapely cheeks to guide him right at her pucker.

"No, no." She instructed as she reached back, guiding his cock downward so that the pointed tip was resting between her lips. With it angled right, she leaned back until she felt him pop into her, his growing member inflating inside her as his muscles tensed. She had to be careful, he was going to continue to expand, much like a knot, so she needed to have what energy she had left focused on allowing her form to be malleable enough to host his expanding flesh.

Still somewhat reserved, Lethias slowly pushed his hips forward, his cock slipping into her one bit at a time until he felt her depth bottom out, and he couldn't push in any further. Most of his length was inside her, the veins pulsating with each heartbeat as he felt her grow tighter. As he looked down over his body, he saw that his forearm was bulging as well, the muscles twitching and shifting form as the skin stretched. It was distracting for only a moment before he managed to piece together what was going on.

With the revelation of his growing form, he pushed in deeper, suddenly feeling her pussy grow more accommodating to his expanding flesh. She got deeper, and looser faster than his member was growing, but that allowed to bury himself to the hilt, her rump cheeks pressing firm against his thighs.

Ceylon let out a moan as his length pierced her depths. She was focusing on her body, directing magics to her nether regions to widen her hip bones and loosen her flesh, opening her womb to his tapered tip. She could feel his member pressing out against her belly, forming a slight bulge as he thrust at her. The gryphoness reached back to hold her tail and keep it away from her lips, relishing the sensation of his arm-thick cock pounding in and out of her to the rhythmic squishing of moist flesh on moist flesh.

It was clear that he was growing inside her as he thrust, spreading her lips apart and distending her flesh from womb to vulva; eash thrust felt a little tighter and deeper, and she loved it. Not only did she love it, but she loved that he was clearly loving it as well. As she glanced back over her shoulder, she could see he had a scrunched look of concentration on his face as he bit at his lip, the tightness of her confines massaging his every centimeter from tip to slit. She could also see his chest muscles were bulging out, pectoral muscles inflating and expanding as he pushed into her. His arm muscles grew and pushed against his scales and the armor plates that lined his forearm.

The dragon was a bit too busy thinking about the tight but comfortable flesh that was squeezing his member so much that he barely noticed that she seemed to be getting smaller compared to him, her muscles relaxing and stretching around him. It wasn't until he pulled himself almost entirely from her depths, leaving only the tip resting inside her tender lips for a kiss, that he opened his eyes and saw that his arms were twice as thick as they were before, and that she seemed to be shrinking.

With his cock still inside her, he plunged it deep again, letting her ebony lips rest against his slit as he looked around. He could see that the trees seemed shorter, and Ceylon seemed smaller. No, he was bigger! He was growing. His muscles were bulging and pressing out against his scales, forming hyper-defined lines around each and every muscle! He had abs, he had powerful looking pectorals! His arms were huge! His legs looked like he was a power lifter!

The sudden realization of his gentle expansion made him push even harder, his instincts telling him that, as a powerful drake, he needed to be in control and that he needed to bury his seed deep inside her.

Ceylon had her eyes closed so she could focus on the sensations, ensuring he didn't grow too much for her to take. She moaned and shuddered with each powerful, aggressive thrust, pushing more magic to focus in her genitals, keeping the flesh malleable and instantly healing itself as it adjusted to his massive girth and length. Before long, his member was half as long as her torso, and nearly as thick, so she felt she might have to employ some additional tactics to accommodate his growing needs. She looked back again and saw that his balls were still growing - even relative to his size - and were hanging down by his knees, and he was now twice as tall as her, rather than just a half meter taller. Not only were his muscles and flesh bulging and expanding, but he was growing, too!

She fought the urge to take some notes about this development, and instead pushed back hard against him, feeling his now-leg-thick cock pressing out from inside her, the base of it nearly splitting her in half under her tail.

He grabbed tight against her hips and slowly increased his pace, slapping his hips against hers as his member stretched her and dilated her vulva beyond max capacity. He felt a bulging wave travel down his tail, then return and go down one of his legs, urging him to stop and let out a roar as the pleasure ran through his body.

Another wave of bulges traveled out from his core and down both of his arm, and he felt one grow longer first, then the other, before the muscles caught up and matched the size and girth. He felt his torso grow, followed by another bulge of muscle up and down his leg. He could literally see the world around him growing smaller as he had nearly tripled in size compared to Ceylon. His height increased fast enough that even spreading his legs and bending his knees had him so tall that he had to pick Ceylon up to keep her pussy at cock's height, leaving all of her limbs dangling, and her feet resting on his thighs for support.

She could have struggled, she could have kicked away, but she wanted him to enjoy himself as fully as he could before the potion wore off and he needed to relax. No, she needed to be a receptacle for his seed once he was done, and that would require her to grow a bit. With her so small compared to his growing form, and her torso taking a specifically Lethias-cock shape, she realized it was time for her to use her magics to match him in size. Well, mostly; she still wanted to make sure that she was nice and snug.

His form continued to bulge and expand, one limb after another, returning to the torso then neck and tail and wings. His chest grew thick and muscled, only to have his legs grow as well, followed by his muscles, then his bones would elongate to match the length of his growing muscle and sinew. One after another, until he was taller even than the trees at the edge of the cellitoke wood. He grinned and growled, howling a bit as he wrapped his hands around Ceylon's form - his hands which could now easily wrap around her with ease, thumb and forefingers on both hands touching each other. As he continued to get taller and his cock continued to bulge out with each throbbing heartbeat, he found more and more that he could not get his full length into the gryphoness that was, at this point, little more than a sex toy to him.

Still, his cock grew in length and girth, so big he could barely get the tip in her any more, even with the colorful mist of magic emanating from her ebony lips.

That was when Ceylon realized she couldn't stay this size forever. His cock was as big around as she was, the tip alone was half the size of her torso, and any more magic making her stretchier would just look comical. Instead, she flailed her arms wildly as she used her magic to expand her own form, limbs lengthening and muscles bulging to meet them. She remained lithe, unlike Lethias, who was growing bulkier and thicker faster than he was growing taller. His muscles remained in tight definition on his entire body, making the blue stripes on his chest look like they were waving.

She came to realize, as the two grew and he continued to thrust into her as he stroked at himself, using her form as a sort of toy, that if they continued to grow, the weight and size would press into the soft earth and destroy the landscape with claw prints. If he continued to grow, the resulting ejaculation would literally flood the forest and kill any wildlife unfortunate enough to be stuck in their burrows. Clearly, she needed to match him and catch his seed when he was done, like a safety net. She also needed to guide him toward the steppe on the other side of the Grand Cellitoke where Ilorek and Valencia lived, there they could step on rocks that wouldn't crumble under the exponentially growing weight of the two of them.

"Over here." She insisted, kicking away from him, leaving his cock glistening with her copious amounts of slick fluid, and still growing without any hole to contain it. She gingerly stepped through the trees, careful to avoid stepping on anything important, curling her finger at him to coax him to follow. She was as tall as the trees, with her head sticking out the top of it, while he was taller than the forest by half his body, so he needed to be very careful. "Follow me." Her voice was a deep bellow, something that came with the territory of growing this large.

Lethias didn't respond, at least not verbally. She caught a glint in his eye and could tell that, while he was still sentient, he wasn't lucid. His feral, carnal instincts were taking over, and now all that mattered was the soft flesh needed to massage him to climax. With that need in the forefront of his mind, he gingerly stepped through the trees alongside her, his massive balls swinging back and forth and crashing into the tree trunks as he went, the underside of his erect shaft sweeping over the leafy treetops.

It didn't take long at all, no more than a couple minutes, for the two of them to reach the bare patch of the forest covered by the rocky steppe. There, they could lean against the Grand Cellitoke as they continued to grow. She felt loose and sloppy, but that was on purpose, she wanted her body to be malleable enough to accommodate his form, that was her design. Still, it would be nice to have him enjoy that first penetration again, where she was tight and needed to be stretched rather than the soft and tender, abused pussy she had now.

Her muscles contracted as she leaned her form against the Grand Cellitoke, tail up as the magic returned her pussy to normal size and conformation. A little bit of healing and transformation magic later, and her lips were as pert and tight as when they started.

Lethias didn't hesitate once he got to the steppe, quickly reaching over to grab her hips in one of his powerful hands, holding her in place as he aimed his pointed tip under her tail again, only this time he couldn't bury himself with ease. No, this time he had to grunt and moan as the very tip of it parter her lips, but her muscles kept him from pushing in any deeper.

He gave a gentle thrust, only to pull out and leave her gaping a little, a monstrous bead of precum slipping out from the tip of his member to dribble down the underside of his shaft and drop to the forest below, splashing at the rocks and dirt in one gooey mess.

Well, not much more time to waste. He was getting close, but he was still growing. He was now half the height of the Grand Cellitoke, and he was steadily growing larger and larger. Luckily, he only had so much mass in his body, so while he was growing larger, he was no longer growing heavier, Extra mass has to come from somewhere, and the potion she'd concocted did not include a matter draw from the nearby environment, so even if he grow to be twice the size of the Grand Cellitoke, he wouldn't get much heavier.

Still, his balls were the each the size of a castle, and both were swinging heavy between his legs, and they would produce so much cum that it would be a veritable disaster, even at this size. She ramped up her magic to grow to the proper size, so that she was to him as she was before either started growing, only a few heads smaller. Once she calculated his height differential and growth rate in her mind, she set her magic centers to the same pace and focused more on making her pussy more cozy and comforting for him.

Once he felt her muscles relax, he pushed in again, using her tail and hips as leverage as ever bit of his tree-trunk thick cock disappeared into her, forming a noticeable bulge in her belly as his pointed tip stabbed into her womb. He let out a deep, and long-drawn out growl of pleasure as he bared his teeth, her sex squeezing his length tight as he rammed it into her time and time again. It felt to him like he was giving a vigorous lovemaking session, but to the rest of the world, it looked like he was mounting her in slow motion, the gradual increase in size leading to a slowing of speed.

Regardless, it was still working for him. He looked down at Ceylon and the rest of the forest around him to see that everything but she and he were shrinking, the trees now only up to his knees as he positioned his feet on two of the rock formations for balance. He grabbed Ceylon's shoulder and held her down as he tried to force himself into her, right to the slit again. His balls were swinging and pressing softly against her ankles as he pushed and pushed, the knot at the base growing a bit too quickly to pop it in. If the knot was growing, then he was clearly ready to finish up, the bulging musculature of his form pressing out against his scales the same way his cock was pressing out against Ceylon's pussy.

One final powerful thrust against her as he held onto her hip and shoulder, and his still-growing knot popped into her, his member pushing deep into her womb as the knot expanded rapidly inside her pussy. With that final bit of pressure, he felt his cock throb and pulsate, each and every vein expanding as his pointed tip splayed out, plugging her womb for the coming flood.

She clenched down and held tight to the nearby trees, keeping herself grounded as she pushed back, her lips tightening around his base, squeezing around the knot as her own clit winked in pleasure, the pressure of his still-growing cock and especially knot pressing against all her internal pressure points. She felt a hotness splash through her as a deep rumbling bellow emanated from his muscled chest, his cum bloating her and inflating her womb, stopped only by the tightness caused by his knot.

He shuddered in delight and pushed into her even deeper, holding onto her hips and resting his weight on her as his seed drained from his massive balls. He could literally feel them shrinking between his legs as his cum erupted into her, but he was still focusing on the hotness of her flesh that contracted and massaged him.

After a minute or two of idle thrusts, his claws digging into her hips for leverage, he found his knot slowly deflating inside her, the tightness of her confines growing increasingly lax. The first spurt of his gooey cum squirted out from between his knot and her clit, splashing at his thighs and dribbling down into the rocky steppe between them.

Ceylon felt this deflation and immediately reached back to press her palm against her lips, closing her vulva tight so that no cum would escape her. She wanted it to be inside her, even as his cock withered back to normal size - well, comparatively normal. As she looked back, she saw that he was visibly shrinking, his body uniformly losing height, length, and girth so that his proportions never wavered, but he was still shrinking. She could feel his cock slip from her, and she had to use all her muscle control to pinch her lips tight so that none of the cum would leave her, though some massive drops still left and splashed out of her.

The only real solution she could think up, at least in the post-orgasm bliss - was to seal herself up, reverting her to a virginal state with two barriers at her cervix and just inside her vulva for additional, fleshy protection. She looked pregnant, and was still almost the height of the Grand Cellitoke as Lethias continued to shrink, so much so that he was barely the size of a normal tree, now, and still shrinking.

She reached down and patted his head as she focused her mind to shrink her form, having all her flesh and bone retract from its gigantism with ease; the only problem was that all that cum was absolutely massive, and she couldn't shrink it inside her, so as she shrunk, her belly got more and more distended until she realized she could compress that fluid, same as she could compress her own form to shrink to the size of a cat. Her magics divided themselves between depleting her body mass and her elemental magics helped to compress the flood-like mass of cum in her womb.

Soon, they were both back to their natural sizes, Ceylon with a distended belly full of seed, and Lethias with a dripping slit and still-engorged balls between his legs, cock tip still gently poking out. He seemed spent, but now he wanted to go clean up. "C-can I clean in the river?" He asked, hands up and away from the cummy mess between his legs.

Ceylon nodded, guiding him away from the Grand Cellitoke and through the woods until they reached the river that parted the valley. There, he waded in until he was up to his hips, and he proceeded to clean himself off. She remained at the shores, watching over him with a dozen questions in her mind regarding the effectiveness of the potion and what might have happened.

Lethias had grown exponentially until he climaxed; had he not climaxed, would he have grown infinitely? Would the laws of physics allow that? If she let the cum flow from her womb, would it revert back to its full volume, creating a veritable flood? If so, what would happen to it? Would she have to leave it inside her, womb bloated and inflated, until it was all absorbed into her system and converted to water and energy?

And now that Lethias was back to his normal size, with his normal vigor restored, would be be eager to have another go? She knew him to be ravenous, so it wasn't uncharacteristic of him to want to go again as the cum's still dripping from her pussy - or ass, depending on the mood.

Eventually, she waded in after him and the two of them enjoyed each others' company, splashing each other and making jokes about what might have been.

One thing was for sure, Ceylon had a lot planned for him that week, starting on this day of his hatching. Next up, he had to meet the others to see what they would offer him, and with each of them specializing in a different realm of magic, she was sure she'd find something else special for him.
