A cold, rainy day has always put people in the mood to sleep, to let their stress and worries wash away. The cold breeze, the rhythmic falling of water, it was all so soothing and calming, especially so with the right items in hand: a blanket, a cup of hot drink and someone to share it all with. It could have been a perfect time to rest and relax.

But instead of all that, a fox and rottweiler couple are instead busy cleaning their closet full of boxes.

"Why do we have so many boxes, Rune?" The orange-furred fox mumbled with awe, trying to comprehend how they all managed to fit all these cartons in this small closet of theirs.

The bulky rottweiler merely chuckled, carrying a box taller than him with ease after dusting off months-old soot, his shirtless, black and brown furred torso tensed at the action, easily showing off his tensed muscle. Rune simply elbowed the tall fox before moving the box outside. "Well, we did pack a lot when we moved out here, Finn."

"That's true..." Finn mumbled, eyeing the bulky rottie waddling out before continuing to try and make sense of everything. The tall, lanky fox sighed and decided to set all the smaller boxes first to the side, letting Rune handle all the bigger boxes.

Still, the fox can't help but feel a bit overwhelmed with all these boxes in front of him, chuckling exasperatedly. "This is gonna take a while, huh?" He could hear the boisterous laughter coming from the kitchen and it was enough of an admission from the rottweiler to know that they really fucked up.

Though to be fair, both of them didn't really know what and what not to bring when the two decided to move in on their own house. They were just excited that after years of working and toiling on their respective jobs, Finn on his gallery work and Rune on his coaching job, the couple of many years finally managed to get their own little home. Suddenly, the overwhelming feeling turned into fascination, nostalgia pouring in as he eyed each box.

"I kind of wonder what we even packed back then." The fox mused before rummaging through the stack of boxes. One box contained a lot of thick jackets and sweaters, apparently he heeded the advice for keeping lots of those for future use. Another contained a few medals and small trophies, all of it relating to sports and other physical achievements. "This one's obviously Rune's." Finn mused, closing that box and setting aside for Rune to carry out.

This continued for a good while, a good routine between the couple as the space inside the closet began to clear out. One by one, it actually looked like a closet and not a warehouse full of boxes. Once things cleared out, Finn began finding more unique stuff inside, like for example, an exercise bike.

"Rune?"

"Oh yeah, I was gonna try and ask you to do some rounds with this baby! I completely forgot!"

An intricate painting that seemed incredibly pricey.

"This...isn't the real deal, right?"

"It's just a replica, Rune. Don't worry. Got it from my co-worker at the old gallery"

And an entire audio system.

"Oh yeah! I remember this! Isn't this-?"

"From my aunt, yeah. Willing to test it out later?"

"Sure! Been a while since I heard you sing, babe."

Everything seemed good so far, the two talking and even reminiscing about their collection of hidden things. Since most of the boxes were gone, Rune decided to go over the boxes in the kitchen, meanwhile Finn decided to stay here for a while and check everything out.

It was then Finn saw something from the corner of his eye. Turning around, he saw a bunch of boxes of various sizes with intricate doodles drawn around them.

Seeing as he was the only artsy person in this household, Finn was pretty sure it was his, but his mind was going blank on what it contained. Curious, the tall fox grabbed one and opened it, and was immediately flooded with nostalgia as he saw what's inside.

"Yeah, this is mine." He chuckled, eyeing the various drawing pads and notebooks he had used throughout the years. He even had that little book that his mom bought for him, the start of his art career. The orange fox closed the box for a while, intent on crying all of these to the kitchen when a boisterous rottweiler came sliding in with something.

"Babe! Babe! Look at this!"

The tall fox looked back and was greeted with the sight of his bulky lover easily carrying a gold trophy that was an inch or so taller than him. Finn could only smile, already knowing what that particular trophy was and already preparing for the upcoming story. "Is that what I think it is?"

"It is! This is the one I was talking about! That wrestling trophy I won back in college!" The bulky dog let the trophy sit on the floor, the very tip of it reaching beyond his head as he looked over at it proudly. "I knew I packed it here with me! I told you about this, right?!"

"Many times, hun." The fox smiled, trying to carry the boxes with him, but it was a bit too heavy for him. Fortunately, the dog ran to his side and easily carried it all, easily heaving the two boxes carefully with one strong arm. Finn could only smile before slightly crouching down and kissing the top of Rune's head. "Thanks, Rune."

"No problem, babe!" The dog went ahead, leading the walk towards the kitchen but not before grabbing the trophy with his free hand. Finn merely laughed at the casual show of strength as he let the dog tell the grand story of a reversal win once more.

"Oh man, I remember it like it was a few days ago! It was the finals match, and it was just me against this large bear in a best-of-five match. I tried my best, but that bear was so good! You saw me back then, right?" The fox nodded before the energetic dog continued immediately. "Right! Because I dedicated the win to you back then, remember? I even shouted it! Anyway, I was down two out of five but I didn't give up! Oh man, I remember that really awesome overhead throw I did, I didn't even think I could do it! Because that guy was HUGE and..."

Finn merely sighed in contentment, letting Rune excitedly retell the story of his grand win, his long tail swinging wildly as he followed the dog back to the kitchen, crouching just a bit on the doorway, his gold eyes eyeing the stack of boxes on the side and already dreading the upcoming task of checking each one out.

The rottweiler set the boxes on the table and the trophy on the floor as he continued his story, his excitement swelling. Finn simply sat on the table sighing, eyeing both of them; the trophy beside him stood taller than his 5 foot 4 lover, highlighting how small Rune really was.

Even more so considering he was more than a foot taller than him.

At 6 foot 6, his little dog could barely reach Finn's own shoulders, highlighting their more than a foot size difference that was made even more comical with the rottie own bulk.

The hound was, in simpler terms, bulky. Rune was heaving more than 220 pounds of muscle and a bit of fat, giving him a strongman appearance that contrasts his energetic personality. The fox, meanwhile, looked comparatively twiggy with his less than 100 pounds of weight, his mostly lethargic personality a complete opposite to the almost howling rottie.

"...and then BAM!" Rune shouted at the top of his lungs. "Three counts in and I won the championshiiiiip!" The dog flexed his meaty arms, his bulk bulging into full tightness as he flexed and posed proudly.

The fox could only laugh, clapping at the nice story and incredible gun show held by the rottie. At the end of it all, the dog rushed towards his fox and hugged him, once again being affectionate by surrounding him with his strong arms before peppering Finn with soft, gentle kisses.

Rune smiled, his green eyes mellow. "I love you, Finn."

Finn chuckled, gold eyes content, before nuzzling each other. "I love you too, Rune."

The two shared a short and sweet kiss before Finn patted the dog's head, their tails wagging around. Rune let go and headed back to the closet. "Anyway! It's my time to check the closet again, okay? There's still some things left, right?"

"Yeah. Check the corners, hun." But the dog had already left, leaving an amused Finn in the kitchen. The fox leaned on his elbow, eyeing the trophy left on the floor. Finn sighed, tapping his fingers on the boxes on the table.

To be quite honest, he didn't really like Rune at first sight. Even back then, the man was rowdy, too energetic for him. One of the moments he remembered by heart was him running around the halls of the college without half-naked, hollering at the top of his lungs because of a dare. He was just...too much at times.

Well, that outlook didn't last long. The short, bulky canine had wormed his way into his quiet heart, and now after many, many years, the tall fox wouldn't have anyone else.

"Heeeey, Finn! You okay?"

Finn looked back to his hunky little dog, boxes tucked under his arms, his shirtless, muscled body heaving, black and brown fur slightly drenched in sweat as he simply stood there, his muscles heave with such power and mass, his shorts tight on his meaty quads. The canine's handsome face looked absolutely adorable in comparison to his manly body with those incredibly cute green eyes and bright smile, a faint brown stubble framing his chin. The man was almost perfect...

...almost.

The vulpine cringed at that errant thought, shaking his head to try and dismiss that thought. The dog asked him again and he responded with a strained smile.

"It's nothing, Rune. Just thinking of something." He said, focus now entirely on the boxes. The vulpine hadn't seen the dog shrug his mighty shoulders but he had felt the kiss on his cheek before the dog left wordlessly.

The fox felt slightly embarrassed and angry at himself for thinking about that once more, a paw clasped at his soot-stained shirt, another laying on his snout as he whimpered. He had long accepted that fact, many times, in fact, and yet...

Before he wallowed in all of it, he took a deep breath and exhaled it with a loud "HA!" Right, he shouldn't let that bother him anymore. Instead he focused on his boxes, opening one and letting himself awash with memories of old.

"Oh, wow..." He mumbled under his breath, gently rummaging through his old stuff, each one holding a precious memory. The vulpine grabbed one pad and opened it, his tail swishing for every page turned as he got greeted by his cringy old doodles and sketches, the start of many to come. "Didn't think I would even have these."

He grabbed another sketch pad and smiled brightly, his fluffy tail swishing on the floor. "Oh, these are from my junior high."

"Ooh, I like this one!"

An arm shot out from his side and pointed at the current page, featuring a sketch of an idyllic sunset made from colored pencils. Finn wasn't even the least surprised when Rune hugged him from the back. The dog was slightly sweatier than before, but the fox didn't mind, especially when he felt those pecs clash against his back. The soft kiss on the cheek was pretty much a bonus. Rune's head popped in with a smile, all while eyeing the sketch pad. "Are all these your art stuff, babe?"

"Yeah. I made it all." He dropped the one he was holding and pointed to the small notebooks on the sides. "See those old notebooks? I'm pretty sure those are from my elementary days."

"Really?!" The dog bounded to the box, his tail wagging intensely. Rune looked at his lover, his green eyes almost pleading. "Can I see them? I wanna see what my fox was drawing back then!"

Finn chuckled, pushing the box towards the eager dog "Sure, hun. Just be careful."

The dog let out an excited howl before grabbing the entire box, leaving a surprised Finn chuckling as Rune sat on the floor and started rummaging through the contents, first carelessly before going at it gently, as if he remembered whose stuff was this.

The orange vulpine could only laugh as Rune showed him various books, notes and art projects of old to him, and the fox would explain what each of them were. Rune even started guessing what kind of medium Finn had used for each of his much more professional-looking pieces.

"Hmm...gouache?" Rune tilted his head, assessing the art piece he was gently holding. "It's gotta be, right? It's a bit shinier..."

"Acrylic, actually. You mixed the two up, Rune."

"Noooo! I was so sure of it, too!"

Their antics continued until the dog continued to look around the fox's works more closely and quietly, as if memorizing the entire thing. Finn could only sigh as he began opening this other box, curious what it contained. Will it be his old portfolio stuff that he had to shelf away? Or maybe it was some of the art pieces from the old gallery? Or maybe-

And then suddenly he was assaulted by an image of a tiny bear, standing precariously on the paw of a titanic bull many times his size, his head looming over him, grinning madly at their tiny bear.

The vulpine was a few shades redder when he immediately closed the box, his gold eyes narrowed on the box whose contents are something he wanted to keep hidden, even for a little-

"Babe, what was that?"

Fuck!

"N-nothing! Rune, it's nothing..." Finn answered nervously, his tail swishing frantically as the bulky dog stood up, a curious look directed at the box in front of Finn.

"Oh, is that box also yours?" Rune asked excitedly, practically jogging his way there and the nervous fox practically grabbed the box away, raising it up as to not let him reach it. "Aww, come on, babe! I wanna see all of your works!"

"Rune, wait! This isn't...!" Finn fought over but it was for naught; the dog managed to muscle his way over, grabbing the box and gently setting it on the table. The defeated fox didn't have it in him anymore, simply going back to his seat and dreading the reaction coming from the dog.

The rottie must have seen this and smiled gently, a muscled arm slung around Finn's shoulders. "Come on, Finn. Relaaax!" Rune kissed him, before letting go, his paws already opening the box. "I'm sure it's nothing to be embarrassed abo-"

And then he opened the box. Finn saw the Rune physically stop, his eyes wide. Even his long tail stopped wagging. The vulpine, accepting his fate, merely sighed and scooted closer to the dog, his eyes wandered at the contents of the box.

Magazines, zines, prints, and posters galore, collected over the years, all with a singular theme connecting them all: macro. A lone giant looming over one or many tinies, showing their impossible size difference in many angles, in various situations. The one in the forefront is a large print of the bull and the bear, and Rune had his green eyes focused on it, his face almost curious, tail swishing as he kept staring at it before grabbing it gently.

All was silent, the fox was studying how the bulky canine would further react. The orange fox had the fur on his back standing on its end, already fearing the worst.

He always had the irrational fear that Rune would hate him if he ever found his stash, maybe it's because he initially took a while for the fox to warm up to the dog and, admittedly, it was because of his height. Bulky and muscular as he was, he was just...short, really, and it didn't help that the fox was taller than average as well.

Eventually though, through simple hangouts and eventually dates, the fox realized that the dog was more than just his lacking height and made up for it with his loving and affectionate side that mashed well with his energetic personality and his hunky body.

Still, he had moments where he felt guilty even just looking at his stuff, that certain feeling of Rune lacking something he can't control coming back every so often and he hated it. It became easier overtime, even managing to add some more items in his collection, but sometimes his desire to see Rune gigantic, absolutely towering and the guilt alongside it came back.

And here it is, with the very man he wanted not to see his stash looking them over with curious eyes. The fox gulped, knowing that he had screwed up, ready to accept his fate as he knew that Rune will definitely...

"Ooh, wow...!" Rune finally exclaimed, his green eyes almost shining. "This is...honestly pretty hot!"

...like...it?

"Huh?" The fox dumbly uttered, his face was like he got slapped hard. He turned around to see Rune's face clearly, a slight blush decorating his cheeks as he kept on smiling so bad at the print, eyeing the print with a mix of curiosity and...hunger? Lust?!

"Man, how huge do you think the bull is in this pic? The bear looks so tiny!" Rune said, fascinated by the print before putting it back and scouring the other items, his tail wagging behind him. Finn watched him with equal parts horror and relief as Rune ogled at the various prints and posters, each one making him just as excited as the first one.

It was a certain magazine, however, that caught his interest even more. "Ooh, this one's interesting!"

The cover of the magazine features a giant mastiff and a tiny arctic fox, ironic considering their situation, and it was something that Finn had always looked at whenever he was feeling horny; the way the artist had perfectly encapsulated the size difference between the two in almost every page was incredibly arousing to a younger Finn.

Rune started browsing, his tail swishing eagerly as he appreciated every page and especially so when the two characters interacted, their extreme size difference showing all throughout, even in casual settings.

The fox scooted closer to the dog, just in time for the dog to stop on a particular page that caught both of their attentions; it was a two page spread that highlights the immense size difference between the two characters; the giant dog lying down on his back with the fox standing precariously on the dog's torso, the vulpine only viewable through a separate, smaller panel on the side, showing how titanic the dog is compared to the fox.

The vulpine remembered that one, too vividly in fact. It was the lone scenario playing in his mind the most after he first browsed it. The amount of nights he fapped to that certain page was embarrassingly high, especially once he started imagining him and Rune in that scenario, with Rune being the mighty giant and him being so tiny in comparison.

With curiosity, he looked over to check Rune's reaction, the dog was almost mesmerized by it, and the fox could clearly see that this entire experience had awoken something in him.

And then he checked lower, only to be greeted with the sight of Rune's own monster waking up, tenting his shorts considerably.

'Oh, god. He REALLY likes it...' Finn thought, still unable to process this turn of events. To think that the little dog would enjoy macro just as much as he does...

"Man, this is really so hot." Rune flipped to another page, the fox now close to the canine's towering head as the canine whistled. "Just look at how big that guy is! The fox looks like an ant against him."

The fox saw how the dog shamelessly adjusted his shorts, grinning as he flipped through the pages. It was still surreal seeing him just...liking macro stuff, and it was somehow a big relief for him. "So...you like it?"

"Yeah! Did you make this one? It looks so professional!" Rune asked as he rummaged on the box some more, seeing various sketch pads and books alongside other merch. Finn kind of blushed with how Rune thought that incredible magazine was his work but he cleared it off.

"I, uh, bought that one, actually. Some of those I bought, but the sketch pads are mine..."

As if on cue, the bulky rottweiler flipped through one and saw pages upon pages of Finn's degeneracy; two figures of different sizes in different scenarios, from the giant holding out a tiny by his fingers, to a small one exploring the giant's body. It was a lot of pages and Finn blushed once more as Rune explored it all so candidly.

But one in particular made the fox sweat nervously. It was a sketch of his lover Rune, quite obvious from the figure's physique, fur patterns, and bright smile, standing several stories tall and flexing in front of a comparatively tiny Finn, looking at the titanic dog while standing on a high cliff which only reached the titanic canine's waist.

Finn let out a sigh when Rune was instead amazed, his green eyes shining. "Ooh, you even drew one of me! That's amazing!" Rune dropped the pad and immediately copied the pose, flexing his muscle to its full size and winked at the blushing Finn. "Man, can you imagine if I was that tall? You'll look so puny against me!"

Finn chuckled nervously, feeling his own weapon rising up because he could, oh boy he could. In fact, he had imagined many, many scenarios of Rune suddenly growing thousands of feet tall, looming over him and showcasing his might against many structures and landmarks that were once too tall for the both of them.

It wasn't until he felt someone caressing his bulge did he notice the bulky Rune now stood close to him, a sultry grin on his face as he chuckled. "Aww, you like that one, huh?"

"Y-yeah..." The fox mumbled, his cheeks continued to burn, the dog chuckled lightheartedly before letting go, leaving the fox a blushing mess. "So, uh...you don't mind then?"

"Hmm?" The dog tilted his head, his ears flopped and the fox couldn't help but smile at the cute sight. "Nah, it's fine! In fact..." The dog grabbed a few more magazines and grinned. "I think I like these, too!"

Finn was both relieved and surprised still. It almost felt like a dream that he didn't want to wake up. "So, this isn't a joke, huh? You really do like macro, huh?"

Rune blinked. "Well, yeah. Why would I be joking?" Finn wanted to hug him right now, he didn't think he needed to hear that but the dog had another question. "Also, is that what this is called? Macro? Like is it short for something or...?"

"Uh, as far as I know, no. It's just called macro. Basically, it's like..."

And the two talked about macro and all sorts of scenarios, with the fox becoming more and more surprised at how...accepting the dog was when it comes to this, showing him more of his purchases from different cons and artists that he had accumulated throughout the years. The bulky canine grinned as he grabbed a magazine, grinning at the fox.

"Well, looks like I know what to do when I'm alone, hey hey!"

Finn could only laugh, the absurdity of it all was starting to get to him. He can't believe he hid all of this to his boyfriend, only to end up with him being a fan of it all. The dog continued to peruse his old stuff, and even decided to continue cleaning up the closet in search for more materials.

At one point, Finn asked what Rune preferred: to be the giant or to be the small one. Rune merely giggled before sweeping the fox off his feet and carrying him bridal-style.

"Ain't it obvious...'little fox'?"

The fox sputtered nonsense and the dog merely chuckled as he carried him around, shouting stuff about being so big that he would tower over buildings, then mountains, all while flexing an arm for his 'tiny' fox to worship. Finn could only chuckle, thankful that his irrational fear remained as one, a big weight lifted from the fox.

Still, Finn thought it would end there. Sure, his dog borrowed some of his magazines here and there, but he thought it would be just that...

***

...and so he was surprised when, only a few weeks later, the dog had a strange request that Finn would never, EVER in his life imagined the hunky dog would ask.

"...you...you want to do what?"

"Do role-play! Or something like that." He said so innocently and brightly, like he was just asked what flavor of ice cream he wanted. (It's vanilla, surprisingly.)

Meanwhile, Finn was thankful he had already swallowed the iced tea he just drank, screaming internally as his mind took minutes to process what he heard. He placed the glass shakily before looking back to his lover. The dog was slightly embarrassed, his paws clamped with each other, but he was still smiling, anticipating an answer, his long tail wagging behind him as if the guy just didn't request...

...h-how the fuck did he even learned about that?!

Finn decided to let his curiosity settle down for a while and decided to ask something else. "So, uh...what kind of RPing are we gonna do?"

That bashful yet incredibly sexy grin popped up again, the dog scratching his head and letting his bicep jump and strain his sleeve, and god was it sexy when Rune did it. "Well..." Rune started, his voice low. "I think you already know what I wanted..."

"I...I do..." Finn croaked, and that's exactly the problem. Finn DID know what Rune wanted, and the problem was that he still can't believe that Rune became like him, a certified macro trash. He was even considering role-play! Never would he think this would happen in a million years.

The two stared at each other, Rune grinning, eyebrows wiggling as the fox merely sighed with a slight grin as well. "...I still can't believe you like macro."

The dog merely laughed boisterously, grabbing the fox by the shoulders and hugging him tightly. "You know what they say, babe, life is full of surprises!"

"Sure is..." Finn could feel the arms of his lover squeeze him, those pecs that he so loved pressing against his thinner torso. "Fine, Rune. We'll do it." The fox relented, but his swishing tail told the smiling Rune everything he needed to know as he smiled.

"Alright! I knew you would be okay with it! So what kind of scenario do you want?"

"H-huh? Wait, already?!"

"Why, sure! We gotta plan and all that!" Rune chuckled, his bright smile almost blinding. "Besides, I know I'll play giant but how do you want it to go?" The dog let go as he stood up from the sofa, his paws hanging forward like a zombie. "I was thinking that I could be the giant that decided to terrorize a city, then I saw you walking towards me and so I wanted to step on you then take you home for more! How about that?"

Finn's jaw slacked, his mind reeling at the amount of things his dog had said. First off, Rune's into stepping someone? What does he mean 'take him home for more'? And wanting to terrorize a city?

And also why does that scenario seem incredibly familiar to him?

"H-how do you know all these things?"

"I've been reading!"

"Reading WHAT?!"

The bulky rottweiler smiled as he opened up his phone to show the fruits of his labor. "Look! I've been researching about it and found this cool website. Check it out!"

The fox's face went from slightly horrified, to curious, to completely pale as the familiar sight of that old role-playing forum he often frequented before haunts him once more, now with a slicker and more modern UI. Even with all the new bells and whistles, it was still the same ol' place filled with degeneracy, and he was lying to himself if he said he didn't miss this website.

But his face turned pure white when he realized that the rottie was apparently looking at his old profile, one tab opened with him asking someone to roleplay the very same scenario! No wonder it was familiar to him. The fox grabbed the phone, Rune snickering in the meantime, as the familiar sketches, doodles, and texts right in front of him haunt him like the ghost of Christmas Past staring down at him and his sins.

Rune continued to snicker, hugging him again. "I was looking for more macro stuff here, there's a LOT by the way, and I came across some of your sketches posted here!" The dog laughed, kissing the pale fox. "Why didn't you tell me about this a few weeks ago? It would've helped!"

"...kinda forgot about it." That wasn't a lie, really. He really had forgotten the password for this account and, after embarrassingly crying about it for days on end, decided to just not bother with it anymore.

Now that he was a bit less aghast, the fox continued silently scrolling through his old feed; memories of posting his trashy ideas and role-playing with strangers, with him being the tiny one, came back to him, washing him in nostalgia. But for every old sketch he saw, every old convos he read, he can't stop imagining Rune in all of those scenarios.

His eyes landed on a particular one, a scenario that had been playing in his mind for many months back then, when he was starting to date Rune. It was where a shorter-than-average guy suddenly started growing. First slowly, adding a couple of inches to their height every day, and from then on became taller than average, then taller than a house, then trees, then buildings, mountains, reaching thousands of feet in height and never stopping, looming over the entire horizon as he reached miles in height with no end in sight and-

"Guess you like that one, huh?"

Finn flinched when his hard-on got grabbed ever so gently. He looked at his lover, who simply wiggled his eyebrows, his smile mischievous. The fox nervously nodded before yelping at being carried bridal style to the bedroom by the laughing Rune, clothes immediately thrown away before pushing the fox onto the bed.

The noises Finn made when the dog started showing off his muscles as he spouted about growing, stating increasing numbers as the seconds went on until he was a veritable giant that vows to destroy the city. The bulky dog started stepping on the slim fox, letting the paws dig softly onto the fox's pelt as the dog teased him about how 'small' he is, how he's only using the tip of his finger to press against him despite using his whole paw in reality, but the two didn't mind at all, absolutely invested in this entire scenario until the two hit their climax, enjoying the afterglow that came afterward, more so for the fox who's still elated by how everything played out.

And the best thing was this continued for weeks, each scenario becoming more and more imaginative as the dog tried many ways to feel like a giant for the both of them. More than ever, Finn just appreciated the effort his dog makes to have this sort of fun for them both, and even more so that Rune was into it in the first place; his irrational fear really was just irrational, but still it pops up most of the time.

'What if he was faking it?' Thoughts like that had kept Finn at edge, but that was all gone as the excited Rune kept doing this. He knew that the dog would never grow into a multi mile giant, probably not even grow a few feet even, but the effort was what counts and Finn felt at ease with his beloved rottie to share some of his more inane ideas.

So when the date of his birthday arrived just a couple of months after, Finn was not prepared for the biggest, grandest surprise of his life.

***

The fresh, cool breeze was assaulting the fox's senses for the past few hours now. Not that he wanted it to stop as he continued to stare at the wonderful sight in front of him. Finn almost had his head out of the window, looking round him as towering trees surrounded them, all standing 50 or even a hundred feet tall, the alpine backdrop further amplifying the beauty of it all.

"Enjoying the view, babe?" He heard Rune say as the fox seated himself properly before turning to his amused dog driving calmly, his smile reaching his eyes. "I told you you're gonna love this place!"

"I really do, hun." Finn said as he pecked the dog's cheeks, their ears swiveling around in delight as Finn continued to look over the horizon. "This was definitely worth a few hour drive."

"I sure hope so! Besides, the view later will be even greater! Just watch!" The two chuckled, enjoying the quietness of their surroundings as they headed deeper into the forest, the pine trees becoming thicker, the road getting a bit bumpier. They're probably miles away from any kind of civilization; the dog's been driving for a few hours now and hopefully by the time they reach the campsite, they would get some rest and eat some well-earned lunch.

It wasn't until the two found themselves in an incredibly open area did they stop, now on their destination. The dog parked the car on the side and hollered. "Here we are, Finn!" The dog immediately undid his seatbelt and climbed out of the vehicle, his face bright and happy as he spread his arms to show the entire place to the stunned fox. "Doesn't this look great?!"

It was, it really was. Finn slowly and carefully got out of the car, brushing his paw against his thick jacket and pants before staring around to admire the beauty of nature. The place itself was clean, benches and even a little counter for cooking.

But beyond that, beyond the fenced cliff was the highlight of this entire place; miles upon miles of untouched, forested land, a river running down in between, dividing the two sides, all while two gigantic mountains towering over it all. Under the noon-time sun, the fox swore the river glittered into a beautiful light blue color. It was all so beautiful, so majestic even.

"Well?" Rune asked as he hugged his lover from behind, muscled arms around him as he tilted his head upward to watch the reactions of his taller lover. "You like the view, birthday boy?"

Finn didn't have to say anything, only planting a tender smooch on either side of Rune's head before smiling. "I love you, Rune."

"Aw, I love you too Finn!" Rune responded with his own set of kisses before giggling. "And I haven't even shown you the best gift yet!" another string of kisses, soft and gentle yet full of love. Finn chuckled as the smaller yet bulkier dog nuzzled against his flat chest right after. "Now that one, I promise, is gonna be the biggest, best gift you'll ever have!"

"You say that every year..." Finn teased his lover, nuzzling their snouts together before kissing him.

"Well, this one is even bigger! Nothing would compare!" Rune exclaimed with a wide smile, his tail wagging behind him as he let himself have another squeeze before letting go. "I'll give it to you after lunch, though. I'm starving!"

Rune immediately ran back to the car, leaving a laughing Finn as he, curious enough, looked below. His tail swished slowly as he realized it was quite a mighty drop, the cliff was a long drop, probably a few hundred feet tall, close to 400 or so. Another shout from the dog snapped him out of it, and he chuckled as he pushed away from the railings and finally followed along.

But not before looking back to the extremely beautiful view behind him, Finn's mind immediately went to those towering mountains looking incredibly intimidating yet beautiful, looming over the forest beneath. An errant thought came to his mind, then.

"I wonder how tall those mountains are."

The pair of towering landmarks are probably a few thousand feet tall. If...if someone were to grow that tall, or even taller, just enough for them to tower over even those mountains, then they have to be...

"Finn! Come on, let's eat!"

"...coming!" The fox turned around and jogged to the table, his mind filled with thoughts of a certain black and brown dog outgrowing all of those natural landmarks. The fox could only smile wryly. Ah, what a dream that would be...

But first, food! And as usual, the lunch was delicious; Rune being the best cook as always managed to prepare quite a feast for the two of them, all of it delicious. With the view all around them and the promise of a much bigger gift on the horizon, the birthday fox Finn was on cloud nine.

After having a simple cake for dessert and some loud singing from the hound himself, Rune immediately volunteered to clean up, practically bouncing with excitement, his muscles stretching his tight pink shirt and khaki shorts as he cleared up the place

"You sure you're fine with that alone?" Finn asked, looking inside the trunk of the car for his bag of art supplies; Rune promised that the view was incredibly scenic so he brought them with him, and he was more than correct.

"I'm fine, babe!" Rune grunted as he closed the door and flexed his arms, his biceps straining the sleeves of his tight pink shirt, the dog deciding to go light despite the weather around here. "These muscles ain't just for show, y'know!"

"Oh, I know." Finn laughed when he felt the dog hug him, strong muscles squeezing him before going back to the table. The fox could only shake his head as he managed to get his little pack of art supplies at the back, but stopped when he saw something weird from the corner of his eye.

"Huh, what's that?" The fox mumbled, shuffling inside to see a brown tote bag stashed secretly beside the driver's seat. "Huh." Finn tilted his head, long, bushy tail swaying curiously. "I wonder if that's gonna be my gift..."

Hmm, probably not, he thought. Knowing Rune, his gift probably has some fancy ribbons tied around it with a heartfelt card tucked somewhere; the dog was just that affectionate and he loved to show it though fancy gifts. Finn nodded, the bag was probably nothing, and besides even if it was his gift, he didn't want to ruin his surprise.

And so the fox, with his bag of art supplies and a little stool they packed on hand, walked away from the car, passing by a jovial Rune waving at him before taking his position near the edge of the cliff, the cold breeze blowing past him and his thick clothes; those sweaters he packed a long time ago finally having some use.

Just like earlier, he admired the entire scenery in front of him, absorbing the view as much as he could as he grabbed his sketchpad and pencil and started drawing, trying to capture the majesty of the scene in front of him; the vastness of the untouched forest, the serene grace of the river, and the towering might of the mountain range surrounding it all. It was a daunting task, and he wasn't really sure what he should do, but this scene was worth drawing.

The sounds of the wind and the delicate scratching from his stencil was broken down by coughing from a few ways behind him, and considering there was only one other person around here, he shouted, asking his beloved rottie.

"Rune? You okay?"

"Y-yeah!" The faraway voice of the dog said, coughing, still struggling somewhat. "Just, uh...choked on water! Yup! Nothing to worry about!"

The fox sighed. Of course Rune would choke on water. Finn wanted to go on and check on him but the dog shouted almost immediately.

"I'm gonna be fine! Don't worry!" Rune shouted, as if he knew what the fox's internal turmoil was. "Just keep drawing! I wanna see what you're gonna do!"

Finn merely chuckled and shouted a thanks before continuing his sketch with a bit of fervor; his little talk with Rune gave him an idea. Now, he started focusing more on capturing the mountains' towering presence instead, making sure the verticality of the landmarks look intimidating...

...before sketching a humanoid figure standing in between, much larger than the twin mountains as the figure surpassed their heights like it was nothing, the very tip not even reaching the figure's waist. The fox chuckled, already sketching the features he knew from heart; from the floppy ears, to the long tail, to the bulky shape of his body and the defined shape of those huge muscles...

He sighed. He was macro trash through and through, but at least now he can show it to Rune, something that he didn't know would happen. He chuckled as he started focusing on his fur patterns. "I wonder if he'll like this..."

"Like what, babe?"

The bulky dog popped in out of nowhere, taking a spot beside him and leaning on the fence. He peeked at what the vulpine was drawing and whistled. "Ooh, that's a big dog you're drawing there."

"Yup." Finn chuckled, sketching the finer details of the figure. Silence enveloped the two as both enjoyed the scenery their own way. Finn looked over to his dog humming a jaunty little tune, his tail wagging while admiring the view in front of him, all the while sipping something some kind of reddish drink from a bottle.

Finn quirked his brow, curious at the bottle. He was pretty sure he never saw that one in the mini fridge Rune packed. The dog probably felt his stare, as he stopped his humming and turned to him, bottle halfway to his muzzle. "Hmm? What's wrong, babe?"

Finn was about to ask, but decided to dismiss it and chuckled, waving a hand to a curious Rune. "Nothing, hun." And it probably was just nothing, so he continued sketching, the dog shrugging his wide shoulders and continued sipping his drink. They both continued to enjoy the silence together, the fox continued to sketch peacefully, the sounds of the breeze passing by and his dog's tail swishing around providing a perfect backdrop for him.

It was all going so well, too. The sketch was almost complete, but a few minutes later, the humming beside him turned sour, becoming somewhat pained. The fox, worried, turned to Rune who was now panting and sweating, his forehead wrinkled as his free paw rubbed along his bulky arm, as if trying to soothe it from some kind of pain, the other paw still holding on to the bottle.

Finn immediately dropped his pad and pen to comfort his dog, rubbing a paw on his solid back. "Rune? You okay?"

"Y-yeah..." The dog grunted, still leaning on the railings, panting hard. Finn checked his temperature, but the dog relented. "I'm fine babe, I swear."

Finn was immediately worried for his dog, trying to think if he had eaten anything bad, but nothing came to mind. Still, he gripped his lover's shoulders tight. "Come on hun, stand up. Let's get you to the car, at least." The tall fox motioned him to stand up, holding out to his bulky arms that felt slightly longer than before, but he didn't mind that. It was probably his worries playing tricks on him. "I know I packed some medicine. Maybe that could help ease the pain."

"Haah...thanks, babe." The dog shakily whispered, slowly breathing and standing up. "Lemme just..." The dog steadied himself on the railing, bottle still on hand. Finn was about to help him, but instead froze, his eyes widened as he watched the dog stand up...and up...and...

"W-what?" Finn felt lightheaded when he saw the dog, his once little dog now magically taller than he was before. Back then, Rune's head was merely level with his shoulders, but now it reached all the way to his nose. The fox flicked his eyes to the ground, looking for uneven ground that might have given the dog a boost in height, but found nothing, only Rune's paw seemingly larger than before. Looking back up, he gasped when he realized that the dog was even taller, growing an inch since he took his eyes off him, as if he was...

"Babe?" Rune held out a hand, expecting the fox to accept it, but Finn was too flabbergasted to move, especially so when he could see him surge taller with his very own eyes, his clothes riding higher than before. It's slow, but it's happening. He didn't know how, he didn't know if he was dreaming, but...

Rune was growing. Somehow, in some way, his little dog was slowly growing.

"H-how?"

"Babe? Are you still there?" Rune finally opened his eyes, wondering what was wrong and gaped at the sight of the fox looking...smaller than before, the size difference between them diminishing for every second, his sight already higher than he was used to despite crouching down slightly. He stood straighter and both jaws dropped on the floor, Rune was now almost as tall as the fox, the pain almost forgotten.

Finn moved closer, his lean torso hitting his lover's bulky one and his jaw continued to drop to the ground, realizing that he only needed to slightly tilt down to meet up with his gaze. And he was still...

"You're still growing, Rune."

They both can see it, and now that the breeze had died down, they could now also hear the dog's body groan slightly, his bones cracking and repairing as the rottie kept on growing until...

"You're..." Finn stepped back, his jaw practically underground as the dog was now the same height as him, the bright smile coming from the dog never leaving as he still surged taller, and the fox's tail swished hard. "...you're taller than me now."

Rune chuckled, his bright smile turning into a mischievous grin as he looked down (!) on the stunned fox. "Hey there, little fox"

The way those words were said sent a tingle on the fox's spine, and even more so when the dog's hunky body continued to ascend, his muscles not losing its size. The vulpine was now level with the dog's mouth and the difference continued to grow. The fox wasn't able to say anything, too stunned to even utter a single thing until the dog groaned in relief.

"Hoo, the pain is gone."

Finn blinked. Right, the pain. The fox saw how the dog stepped back, stretching his mighty shoulders around and feeling his body, laughing at his clothes. "Oops, probably should have removed my clothes first, huh babe?"

Finn hadn't even realized that, too focused on his lover's growth. The now-smaller fox allowed himself to look down, seeing those poor clothes got stretched to near-ruin. The poor shirt was becoming more and more of a crop top, only hiding the man's pectorals and showing off the dog's thick midsection for the world to see. His khaki shorts that were a perfect fit for him had devolved into boxers that barely covered his meaty quads, and both garments are still being stretched to its limit as the dog continued to grow, and grow, and grow!

The fox looked up, the dog now a veritable giant that towered over even him, a sight that he rarely saw considering his stature, and to think that a few seconds ago, this man in front of him, this absolute giant hunk was more than a foot shorter than him and now...

That thought made him stop, looking straight ahead at the stretching dog, honing on those shoulders. He walked closer to the dog, eliciting a curious hum. "Babe?"

It was then the dog noticed, so did the fox; their size difference was now switched, the fox was now level with the bulky canine's shoulders.

"You're...probably 7 foot 10 now..." Finn breathed, feeling lightheaded as he admired his now giant lover, tilting his head up to see that proud smile looming over him. "You...look good being this tall, Rune."

Rune chuckled, flexing his arms above the fox. "I really do, huh babe?" The dog did a few more poses before relaxing and looking down at the stunned fox. "So do you! You look so cute this small against me."

The fox couldn't help but whimper. Rune being so confident was nothing new, but with this new height of his, it felt more...cocky. Suddenly, those roleplay sessions he had with Rune felt like nothing, especially with the real deal happening right in front of him.

Rune chuckled, his chest bouncing as he placed a paw behind Finn and pushed him against him, giving him a faceful of rottweiler pecs.

"Mmpfh!?" Finn groaned, surprised by such a show of power before practically melting. Those powerful pecs he liked were now pressing against this face without him crouching down or kneeling, strong arms wrapped around him, now longer than ever as Rune chuckled from above.

"God, you look so small from here. Is this how you see me every day? It feels so nice."

Finn could only agree, his erection incredibly tight against his shorts, rubbing against Rune's very own boner that evidently grew alongside him, if what the fox could gather from grabbing the massive canine shaft in between them.

Shit, even that grew too. The monster had broken free from its fabric prison and was now snaking in between them as it went hard. Just like his muscles, his cock grew proportionally, which was insane considering he was already hiding a monster before, not it felt so immense, the fox whimpering for every twitch he felt.

He felt Rune chuckle, a large palm that could grab his head easily petted, making him close his eyes. "Aww, is my little fox enjoying this as much as I do?"

Finn nodded, feeling those strong, much longer arms wrap around him, that massive dick in his torso, and that massive paw? He was simply on cloud nine. The orange fox stayed like that for a while, hugging his grown rottie as much as he could, feeling his longer, muscled back with his own hands.

It wasn't until he heard gulping that he opened his eyes, the sight of Rune sip his drink, that bottle of red juice once more. Their eyes met, and Rune smiled as he gulped a bit more and more of the drink, finishing the entire bottle in just a few gulps. The taller rottie chuckled, giving the bottle to the stunned fox.

"Hold this for me, babe?"

"S-sure..." Finn grabbed it shakily, stepping back a bit by the time Rune released him. The fox looked over the taller canine once more before setting his eyes on the mysterious bottle, skimming through the description until he saw a certain word.

'Grow.'

"Huh?" Finn ignored the chuckles of the taller Rune, focusing on the description.

'This wonderful drink will make the drinker grow into new, wonderfully towering heights! Take a sip and be a giant!'

Finn was almost shaking, rereading the description, with a bit of disbelief. "W-wait, is this real? There's a thing like this?"

"How about you check me out and find out, little fox~?"

Finn turned to Rune and found his jaw dropping once more, the bottle in his hand forgotten and dropped. Rune was...incredibly taller than earlier, and it wasn't even a minute! Finn's head was now level with the giant's chest and was still slowly changing as the canine continued to grow taller and taller, passing 8, 9 feet easily. His clothes became several sizes smaller, more rags than clothes as they couldn't handle the growing, muscular stature of the towering Rune. His sights flicked between the bottle on the ground and the continuously growing canine, now looming over him with several feet more than him, the rottweiler now more than 10 feet tall. "It's...real?"

"Real and working!" Rune chuckled, flexing his arms as he was finally free of his clothing, the 11 foot tall giant canine was now naked, muscles heaving, his erect cock standing erect and proud.

"See this, babe? Your little dog is growing FAST!" The growing canine smirked before stepping a large and still-growing paw forward, comparing his taller physique with the stunned fox. He looked down, enjoying the view of his once-tall fox shrinking until his head barely reached his waist, the ground moving further away as he continued to grow. "What's the matter, little fox? Enjoying the show? Cause I AM!"

Finn couldn't believe it at all, feeling lightheaded as he saw Rune's large cock flopping in front of him, massive arms flexed above him. The absolute sight of Rune growing larger and taller by the second made him incredibly aroused. A dream that he thought, no, that he KNEW would never happen was happening right in front of his very eyes. The fox could only stare as the canine grew beyond 15 feet tall, now 18, then immediately shooting over 25 feet tall. The fox was now level with the rottie's calf muscles and still he was growing.

Finn was starting to pant lewdly, quickly removing his pants and jacket before grabbing his cock out, and jerking himself off as he kept on staring up and up and up to the giant rottie. "You're still growing...Rune, you're becoming a giant!"

"Hell yeah!!" Rune shouted at the top of his lungs as his body shot immediately to 30 feet tall, the growth unrelenting. The surging canine had to bend to his waist just to see his little fox, looking more and more like a toy against his powerful, still-growing body. Rune could only chuckle, as the fox visibly shrank from his point of view, the fox's ears could barely scrape by his ankles, his entire body smaller than his massive, concrete-breaking paws.

Which reminds him, he had to make sure his little fox was enjoying his gift, not just him! So he guessed it was time for the next part of the gift then!

Finn gulped when he saw the giant canine chuckle darkly, surging a few feet in height once more as an added effect, both dreading and eagerly awaiting what the dog would do next. It wasn't until the canine rose an incredibly large foot up did he realize what he plans to do next.

Rune smirked, seeing that long bushy tail wag so fast, his toes curling as if to tease the little fox now underneath his growing paw. "May I, little Finn?"

Finn was almost panting, jerking himself off shamelessly as he nodded and screamed. "Yes! Fuck yes, Rune!"

He heard the dog chuckling as the mighty paw surge in size, no bigger than their own vehicle, looming over the fox and began to lower itself. Lower and lower it goes until the very paw was pressing against him, forcing him to crouch down.

"Aww, are you trying to fight against it? You know it's no use?" Rune was right, it was no use. But Finn enjoyed this little game as he pushed up, trying to fight the inevitable. Yet still the massive paw pressed against him, and Finn's knees buckled at the pressure being exerted, enjoying this fruitless endeavor as he knew who would win, enjoying the feeling of such a massive paw crushing him against its weight, all until he was now flat on the ground.

"Bam! And I won! Guess it's time for me to punish the loser, eh?" He felt the giant chuckle. Finn squirmed as the paw rubbed him up and down, in circles until he was well acquainted with the paw above him, feeling his body smashed just right as the paw rumbled, growing bigger and bigger still. Above him, the dog continued to gloat, his role-playing voice now deeper as it should for a giant like him.

"Oh, is the little Finn enjoying my paw that much? I could feel your tiny squirming from here~" Rune chuckled, enjoying the feeling of growth and the sensation of his tiny fox trying to move underneath his paw, feeling the increased size covering more of him than ever as he continued to grow and grow and grow, so so close to a hundred feet tall if he was right.

"If only you can see me right now, little Finn. I'm practically growing taller than those pesky apartment buildings back in our home! You have to find a bigger place for me, babe! Our home's too tiny for this growing hound!" Rune laughed boisterously, his role playing now a reality as he actually grew, and kept on growing still, reaching heights that weren't natural, all while pleasuring his fox.

Of course, he made sure he was gentle, but he can't help but put a little more pressure, his cock twitching at the very sensation. "Shit..." The dog moaned, being forced out of character as he felt close to the edge, rubbing a paw against his proportionately grown cock, jacking off to the intense feeling of his body growing, his limbs and torso stretching, all while stepping on his tiny fox. "Shit, this feels so... so good."

Meanwhile, the fox was enjoying the added pressure and more, feeling the paw rock him up and down, the firm paw above continued to press against him. The fox was squirming for every movement, especially so when he felt his cock pressed by the giant, still-growing paw as well, being rubbed up and down by the soft paw pads of his gigantic lover. The fox moaned, feeling so close to cumming as the paw continued to grow, surging sizes that would easily cover an entire parking lot, enough strength to crack concrete and yet ever so gentle when it came to him. That controlled strength and the size of his paw was turning Finn on immensely.

And so did Rune. The still-growing rottie was on the edge of his erection as he grew past a hundred feet tall, his large hand rubbing his twitching cock as all the sensations hit him; the fact that he had to be gentle with his tiny fox, the size of his paw compared to their car, his sights rising higher and higher still as he surpassed the towering pine trees surrounding the area, and of course, the growth that was continuing to give him so much size and height, it was all so erotic and arousing to the growing dog.

"Haah...haah...Finn, I..." Rune moaned, breaking character as the sensations were too much for him. He didn't mean to, but he put more pressure on his foot, making the fox moan so loud underneath which only egged the dog further as both him and his growth was at the throes of reaching his climax. "Fuck! Finn!"

"Rune! I..." The fox was a moaning mess underneath, especially when he felt the paw press against him harder, all while literally dragging him on the ground. He could feel his cock pleasured like crazy, and the fact that this entire paw was Rune's was egging him further. "Rune, I'm gonna..."

The two can't help it, moaning, and for the fox's case squirming as they finally let their climax explode. Rune felt his entire body wobble, his knees weak as he felt the first blast of cum leaving him, painting the ground white with his hot seed. He tried to hold on to something, but anything close to him was too small for him to keep him stable, so Rune simply held his ground, lazily jerking himself as he felt his orgasm continue.

Rune holding his ground had a different, but welcome effect on Finn, who remained pressed against the ground as he finally came as well, painting the underside of Rune's foot with his own cum as well as his own body. The fox moaned in time of the moaning giant as he emptied his balls all while being pressed.

It took a couple of minutes for the giant to finally finish, sighing in relief. "Whoo, that was intense." Rune mumbled as he sat down, shaking the earth beneath him when he landed. "Didn't think that was another side effect from that drink."

He slowly rubbed his softening dick, feeling its new heft and size with his hands, probably now weighing hundreds of pounds due to his growth and chuckled. He looked around, enjoying the way the trees looked incredibly small as his eyes landed on their car.

"Woah, it's so small." He chuckled as he easily reached out to grab it with one hand, marveling at how the car that he could barely touch the roof of before was now like a toy to him, turning it around here and there as gently as he could. Rune chuckled. "Aww, guess babe was right. This was a small car."

Oh, that reminds him. He probably should check up on his tiny Finn. He chuckled, just the thought of calling him tiny gives him such pleasure and excitement.

The giant rottie gently set the car back down to the side, and searched for his tiny fox by his feet. And lo and behold, there he was by his left foot, practically glued at his paw pad and looking incredibly tiny. Rune almost laughed out loud. If he thought the car looked so small then his tiny Finn looked downright miniscule! Rune cooed at the sight of his little fox pushing himself out of his paw, but a few thoughts suddenly popped in his mind, making him smirk and snicker.

Finn, unaware, tried to push himself out of Rune's paw. He rubbed an arm around his torso, feeling the pressure of Rune's foot earlier finally hitting him. "Ow...okay, yeah. That does hurt a bit." The fox felt the breeze hit him and the foot that he was stuck to, sending shivers to his spine. "Shit it's cold, how high am I..."

Those thoughts never continued beyond that, as he felt another soft, firm wall pressing against him on his back. The fox turned his head around, only to find himself whimpering to the realization of it being Rune's other foot pressing him, pinning him in between the canine's soles.

"So." Rune started, grinning while he pleasured the fox with his mighty soles. "You enjoying the gift, babe?"

Finn practically melted, practically purring as the 150 foot tall bulky canine kept on squishing him with his feet, even squeezing him in between those mighty toes bigger than his torso. He heard the gigantic dog chuckle, clearly enjoying toying him around as he squirmed happily in his little piece of heaven provided to him by Rune; he probably felt like a pebble to him, with how small he was compared to him and he knew it was turning him on as much as it was to him.

On and on this goes, the fox threatening to cum once more just with the very sensations of it all, the sight of his giant dog gently stroking his erect member as big as a damn silo, just as turned on with this entire scenario didn't help at all. Finn whimpered as Rune applied the slightest increase of pressure, enough to make him orgasm once more.

"Shit...!" Finn felt his balls lurch, firing blanks against Rune's gigantic sole. The fox could only groan in pleasure as Rune just kept on pressing him, playing him with his toes and soles despite it all. "God, Rune...this is so good..."

The giant could only chuckle, prying his hands off his engorged cock and poking the tiny fox with his giant, meaty fingers. "And to think, the gift ain't done yet, babe!"

Finn flinched before practically melting when the giant's fingers enveloped him, still reeling from everything, from Rune being a giant, to how he even became that, that it had just now set in that THIS entire thing was Rune's gift to him. Two towering fingers gently picked him up by the tail, making sure he was unharmed, before depositing him on the ground in between his legs.

Finn found himself back on solid ground and sighed in relief. Sure, it was a nice feeling being played around by such massive, firm stompers, but he also wanted his own pair to feel solid ground. He looked around, gulping at the sight of those massive, muscled thighs barricading him, trapping him inside this little dome Rune made; he barely reached half of the muscle wall around him. Despite his height increase, Rune never lost the mass that he worked on for years, making him a true muscle giant.

And then he looked in front of him and almost whimpered at the sight of Rune's towering cock and massive balls. The cock stood like a proud statue, tilting to Rune' left, thick veins wrapped around it, twitching occasionally. And those balls, Rune always had such a massive pair, but those seed makers look just as tall, if not taller than the fox himself.

Finn moaned, his tired cock standing erect once more. He wanted to go there, be smothered by those orbs, to touch that monolith of manliness. But apparently, Rune has other plans for him, apparently as he heard a loud thud coming from behind him.

"Whoops! Sorry! I hope I didn't break it that much!" Rune giddily shouted as Finn looked over and saw their vehicle, a few dust clouds beneath it ceiling him on what happened. Finn was having mixed feelings on the matter: for one, that vehicle wasn't cheap, but on the other hand, good god Rune can just pick their vehicle up like it was barely even a toy.

Finn heard a rumbling chuckle as the giant loomed over him, casting a shadow over him as he pointed towards the car with a massive finger. "Can you be a dear and grab something for me, babe? My fingers are too big to even fit inside, hehe..."

Finn's arousal was back in full force at that statement, and even more so when Rune dutifully showed how even his pinky was unable to fit inside, his mind torn between wanting to jack off at the scene in front of him and scolding for Rune for potentially ruining their car. "R-rune, I'll...! I'll get it, I get it!"

"Thanks, babe!" The giant rottie dared to chuckle, Finn quickly jogged to the car else the giant might have other plans, his playful nature still present as a giant. As he went his way, he almost stumbled over something, making him trip and almost fall to his ass.

"Woah! Finn, you okay?" The giant exclaimed, his massive, encompassing paws hovering around his tiny lover. "You're not hurt, are you?"

Finn groaned, keeping himself steady as he massaged his ankles. "I'm fine, hun. But what was that...?" He looked back, and saw something familiar.

An empty bottle.

Finn quirked a brow before walking toward it and picking it up. He felt the giant move in closer, quite obvious as the shadow grew bigger, encompassing more of the land below him. "Oh, is that the bottle? I can't really see it clearly from here." Rune's chuckles and statement made Finn breathe in, keeping his libido in check before ignoring him, reading the description in full.

"'Guaranteed to make you grow', huh?" The chuckles coming from the giant looming over him was proof enough that it really worked. He kept reading the bottle, quite a few descriptions and warnings on the label; considering its effects, all those warnings are justified.

One warning, however, stood out to him, causing him to feel that arousal coming back in full force.

'Warning: if more than one bottle was consumed, the resulting growth will increase exponentially. Drink in caution!'

Finn's grip on the bottle tightened as he thought of the implications. More bottles means even bigger, if Rune drank more then he would turn from a hundred foot tall giant to something like a thousand foot tall titan.

And...and Rune said there was an even bigger gift for him too, right?

"Babe, I'm waiting~" Rune snickered, as if the giant knew what the fox was thinking, or maybe it was obvious with how Finn's tail was wagging, or how he bounded to the car almost immediately, making the giant laugh. "Calm down, little Finn! I ain't getting anywhere away from my tiny birthday boy."

Finn steadied his pace, power walking towards the car, opening the door and immediately searched around. "W-what am I looking for, big guy?" He stuttered in his normal volume, till he realized Rune probably hadn't heard him. Surprisingly, Rune replied with a chuckle.

Rune chuckled. "Aww, you called me 'big guy'. Anyway, it's a little tote bag by the driver's seat. It's quite hidden!"

"So that's what it was..." Finn mumbled to himself, the mystery of that bag finally revealed as he looked over the driver seat and saw the tote bag just as where he saw it earlier. Grabbing it, the fox closed the door behind him and immediately looked inside it, his tail standing straight up at what he saw.

"Soooo..." Rune started, knowing what was inside that little bag. "Just what have you got there, little Finn~?"

Bottles. Four bottles of the same thing, weirdly chilled for some reason. All four bottles felt like they were equally staring at the shocked Finn, the warning he read earlier repeating on his mind along with images of Rune, standing tall, then taller, then even taller than what he was now.

"I..." Finn could barely even speak as he felt his balls lurch. He hadn't even realized he had come right then and there, the thought of his 'little' Rune becoming even bigger than he was now had immediately caused the fox to orgasm.

Rune laughed boisterously, his voice ringing at the fox's ear as he saw the 150 plus foot Rune move, the fox whimpering as the giant rottweiler slowly stood at his full height, massive paws pushing himself up. Higher and higher the giant canine stood, all the while looking down at his little, stunned fox, practically eating up the sight of his tiny fox getting smaller and smaller from his view, looking like an ant against his massive stompers.

Meanwhile, Finn was simply amazed by what he was seeing. This massive, towering giant right in front of him was simply too huge; it felt like he was in front of a towering skyscraper, only furrier, and heaving such large muscles and an equally large dick. Seeing Rune move his massive muscles heaving with so much heft so easily, his mass proportionally grown alongside his height, made him moan lewdly. He wanted to feel those muscles himself, but Rune had other plans as he, with his impossible agility, climbed down the cliff.

"Rune?!" Finn shouted. "What are you-?"

Rune merely winked at him before falling down, causing a loud thud that rumbled the earth. The vulpine, tote bag in hand, ran towards the cliff and was about to look down, but immediately stepped back when a large, handsome face popped back up with a wide smile alongside forearms thicker than one-way streets as Rune leaned on the cliff's edge.

"See? I'm fine, babe." Rune said, raising an arm and flexing it hard, the rising peak bigger than a vehicle and Finn could feel his mouth drool seeing that massive bicep. "Besides, I told you, I got a BIG gift for you." The dog smirked, enjoying the way his tiny fox squirmed from seeing him so close in front of him. "Now come on! I can't open the bottles myself, fingers too big and all that, so you know what to do!"

Finn simply stood there, practically shaking, so incredibly eager to grow his precious rottie as he grabbed a bottle from the bag, feeling those expecting green eyes staring at him, his mind still repeating that one warning.

Exponential...exponential...the more bottles of that drink Rune will consume, the more he would grow...the more Rune...would...

Finn let himself smirk as he grabbed another bottle out of the bottle. With two bottles out, he walked slowly towards the looming face of the dog who grinned widely at what he saw, his massive tail swishing in the air, causing the wind to blow around him.

"Oho, someone read my mind!"

Finn chuckled as he moved close enough to fully admire the size of Rune's head; it felt like walking towards a looming stadium, except Rune had beautiful green eyes and a handsome face showing his eagerness. "Rune, we've been together for a long time, so I know what you wanted."

Instead of agreeing with him, Rune merely scoffed a bit, narrowing his eyes on the suddenly-surprised fox. "You still hid all those macro stuff from me, though."

The fox winced, gently setting the bag and the bottles down as he shamefully scratched his head. "Sorry, Rune. Really. I...I thought you would hate me because..."

"Actually, I'm still confused about that." Rune interrupted, tilting his head to the side, adjusting his stance a bit. Finn just realized that Rune was lifting himself up. Despite being a giant, his feet still can't touch the ground like this. He returned his attention to the giant dog who started asking him. "Like, why would you think I would hate you if I found out you like macro?"

"Well, because...! It's...well, I like tall guys, like giants, like REALLY tall guys and then I...well, you're shorter than average, I mean, so I thought you would think...I...was...not into...you and..." Finn tried to fully articulate everything, but the further he went the more he was unsure and terribly embarrassed, especially with how Rune was just...staring at him. Not angry, not even sad, just...confused.

Finn sighed, shoulders drooping. This entire thing really was stupid of him.

Silence permeated the area around them, the fox slowly stewing at the embarrassment before slowly whispering. "You...really don't hate me?"

"Of course not! Finn, listen here." Finn looked over to his giant's rottie, hovering a paw over them and gently petting them with a finger. "I love you. Like really, I really do, and I'm not gonna get tired of saying that, you hear me?" Rune exclaimed, and Finn purred against the giant's gentle touch.

"This entire thing is for you, babe. When I got the chance to be a giant, I jumped at that chance because I thought you would enjoy it." Rune exclaimed before whispering to himself. "No matter how sketchy that wolf-dragon is."

"Uh, hun?"

"Ah, sorry." Rune shook his head, his encounter with a certain someone now out of his mind. "Anyway, yeah! I thought this would be a good gift because you like macro and, uh..." Rune scratched his head, chuckling nervously. "For, uh, thanks for showing me those macro stuff, too. Nothing wrong with us bonding over the same interests, right?" Rune flashed his trademark smile and Finn could cry right then and there. Hearing those words was still a big relief to him, tears forming in his eyes.

"Rune, I..."

"Besides, if you love me even when I'm short, that means I did something right, right?" Rune cheerfully boasted and Finn couldn't hold his chuckles from coming out. The dog retracted his paw away from the fox as he started boasting, his massive chest swelling with pride. "Admit it, babe. It's the muscles, isn't it? I'm just too buff to resist, huh? Or maybe it's my smile! The guys back in the team did say my smile is attractive, so that's gotta be it, right? I mean, a lot of the newbies back on the wrestling team even confessed to me back then! I even told you about the intern who had a crush on me right, Finn? Dude was checking me OUT, even from afar!"

The fox couldn't hold it no longer as he let out his mirth, hands on his knees as Rune kept on listing his good qualities, leaving him almost breathless as he leaned on his giant rottie lover, who started laughing alongside him before they both went silent, enjoying each other's company. The two enjoyed the cold breeze, up until Rune spoke from his giant heart.

"I love you Finn. Don't forget that."

"I won't." Finn mumbled, stroking what he could of his rottie. "I love you too, Rune." He heard Rune chuckle, both of them not even questioning how they could hear each other at this point as they enjoyed each other's company.

At some point, in the middle of this loving warmth, Finn realized they were in the middle of something, eyeing the two bottles and the bag just beside him. He smirked, patting the lower lip of his beloved. "Now come on, Rune. Aren't you supposed to grow even taller for me?"

The sound of that massive tail swishing came back and made him chuckle as he opened the two bottles. He turned around and saw Rune's massive jaw slightly open and was about to climb when a huge hand hovered over him.

"Just leave it to me, babe." Rune adjusted his hold on the cliff once again, before grabbing Finn by the tail on Finn's cue. The giant dog easily lifted him up, just enough for him to stare at the insides of Rune's mouth. The fox's eyes widened, gulping as he saw the wet, massive cavern in front of him, eyeing the incredibly wide tongue just lying there in the bottom, every second Finn could feel something awaken inside hi-

"Babe? You okay over there?"

"Uh, yeah! Sorry, lemme just..." Finn blushed as he eventually poured the contents of the two bottles, hoping to God that Rune would never get the same awakening as he did just now. He could feel the fingers holding him trembling before he got to finally feel the ground on his feet, just in time for the dog to squirm in his position, his body heating up even more than before.

"Ooh, the kick is stronger this time." Rune winced and Finn could only watch as the dog twitched a bit; the reaction really was strong with two full bottles instead of slowly sipping one. The dog gently climbed down the cliff. Finn ran towards the railings and looked down, where Rune shakily landed with a loud thud, the giant root merely half of the jutting cliff's height.

"Wait...wait for me there, F-Finn...!" Rune screamed as he clenched his bulky body. Finn could see, even from his higher point of view, how Rune inched higher and higher, adding entire feet in seconds, then another, then another, the giant hound's body quaked with power waiting to be unleashed.

"Here....it ...COMES!"

And it wasn't long as Rune, just like what the bottle warned, grew exponentially as the dog SURGED 50 feet taller in seconds. A shockwave of air almost blew the fox away, the size difference of the canine and the mass of land disappearing faster than the both of them anticipated. It wasn't long before the black-brown furred dog became visible once more, his eyes peeking just above the cliff, and both Rune and Finn had no time to enjoy this as Rune grew too quick, showing off his muscled neck, a pillar of strength that was wider than most houses as his muscles retained its size despite such a drastic height change.

Rune shot Finn a strained grin, enjoying the growth while suffering the enhanced side effects. "H-hey there, little-UGH!" The rottie shot up another 50 feet, panting heavily as he tilted his head way down to continue looking at Finn.

"...l-little fox." Rune grinned as he saw his tiny fox turn downright miniscule standing and staring at him by the cliff, the cliff that he was slowly outgrowing as more and more size poured into him, making him beyond 600 feet tall.

Finn could only gawk, hand stroking his member as Rune continued to surge taller and taller, tripling his height from earlier and surging even taller than that, stumbling backwards as the effects of the drink kept on going and going. Rune laughed boisterously, completely enjoying the sensations of his growth as obvious from his twitching, hard cock.

"FINN! You think I was a giant before, well now I'm even bigger!" The proud titan of a dog flexed his arms, as he saw the cliff barely reach his waist, still shrinking.

Finn could only let his jaw drop as the dog in front of him grew taller and bigger, beyond even the skyscrapers of the city. The man has to be close to a 1000 feet tall now, and there was no end in sight.

The fox panted heavily, jerking himself off as the giant canine in front of him grew to immense sizes. The man was beyond taller than a building, he was becoming an entire mountain on his own, and Rune was still growing!

Rune started to breathe heavily, feeling so much pleasure from his growth. The cliff looked more like a mere step to him, his head high in the sky both physically and figuratively. He was having so much fun, seeing more and more of the horizon beyond the open space, the field of small pine trees and a singular road, but he was becoming too huge for the cliff that he had to step back, his steps were like explosions despite how gentle he is, and Rune could only laugh proudly

"Haah, I'm growing SO TALL! I'M BECOMING A TITAN, FINN! LOOK AT ME!" Rune shouted as he flexed his arms up, reaching heights that would make skyscrapers jealous. He stumbled back, further away from the cliff, easily traversing the massive, forested expanse below like it was nothing as he moved closer to those mountains.

There was just too much of his once-little canine. Rune had easily surpassed 1500 feet tall and was still growing, growing taller than literally anything Finn had ever seen, his head passing by some clouds as the massive hound kept flexing those longer limbs, his pecs heaving with size as his torso lengthened. The growth truly was exponential and Finn was actually both scared and aroused at how it seemed like it would never end.

...it would end, right? Finn's cock lurched at that errant thought, because what if it didn't? What if Rune just kept on growing and growing? The thought of his once-little dog now taller than anything in this earth, taller than the earth and even more, playing with the earth itself with his looming paws sent him to the edge, quickening his pace as he jerked himself off at that thought. A titan, no, a celestial body, a god. Rune would have been bigger than the planet, and what if he still grows, even more and...

"Fuck..." Finn couldn't hold it longer, his knees weak as he came pitifully, tired from his two other orgasms earlier, the backdrop of his dog growing and growing still continued. Finn kept on looking up, trying to see all of his giant dog as Rune kept on walking back, giving him space and yet taking it all with his size that reached...shit, is...is he 2000 feet right now?

The tired fox was now sitting down, letting his cock twitch and fire blanks, his gaze never leaving the giddy dog as he realized that he had surpassed most buildings, even small mountains with his monstrous height. "Finn!" He heard him shout, his voice traveling far and wide. "I'M STILL GROWING, FINN! LOOK AT ME!"

Rune was simply having the time of his life. His growth was unrelenting, his limbs and torso lengthening at such a fast rate that it makes him shiver, and the pain subsiding till it was negligible; he'd encounter worse things from practice! The 50 foot trees by his feet felt like blades of grass, too tiny for him to bother, and his mind immediately went to his tiny fox.

Fuck, should he even call him tiny at this point? His beloved Finn was even smaller than an ant against his growing might, and their difference in size would only go further and further. The dog growled and whined, his cock lurching and twitching as copious amounts of pre smothered the ground below, his thoughts went from his arousing growth to his miniscule fox as he placed a hand by his snout and another stroking his massive cock; the thought of Finn exploring his body, walking all over his torso, his tiny, tiny footsteps barely being felt by the massive dog was too arousing.

"Oh, fuck...!" Rune shivered as a massive growth spurt erupted him to a mountainous 3000 feet tall titan, and yet he could feel that those couple of drinks aren't done with him; more and more it goes on growing hundreds of feet tall a minute. Those two bottles are working overtime and it sends his mind in a pleasurable fritz, his mind stuck on his minuscule fox trying to traverse his muscled torso with a car, going from his waist to his pecs would be hours on its own.

Shit, how tall would he have to be for that to happen? Was he already there, or should the growth continue? Even more, his mind supplied, his growth was addicting as it was incredibly arousing; this is the best thing he ever had and he hoped that his tiny fox was enjoying this just as much as he did.

Shit, Finn. His mind once again honing in on his tiny beloved as he grew close to 3500 feet, clouds started hanging by his head as he stroked his massive member. Fuck, even the thought of Finn traversing his cock, looking absolutely small against his member to the point that he could barely, no he wouldn't even feel him. He was such a titan, and he was still getting bigger and bigger still. How much would he ever grow at this point? The bottles warned about it, but how exponential was the growth at this point? He was so close...

Rune looked around, panting heavily with his tongue out as he checked his surroundings. His green eyes widened when he saw the very mountains that tower over this beautiful horizon barely reaching his shoulders and was slowly sinking further down for each of his breaths. Rune chuckled, then full-on laughed as the mountains are now by his pecs. He was officially bigger than the mountains! Rune grinned as he turned around and down, looking at the tiny orange dot. "HEY, FINN! LOOK AT ME!"

"Huh? Oh, fuck..." Finn mumbled as he saw the giant, growing hound standing taller than the two mountains on the horizon. The titanic hound stood straight as best as he could as he felt his spine elongate, his body stretched as he flexed his arms, biceps larger than hills bulging above the twin mountains as he shouted, declared to his horny lover.

"YOU SEE THIS, FINN?" Rune smirked as he felt his body continue to stretch upward, more and more until he surpassed the twin mountains, the peaks halfway his head. "NO NEED TO DRAW, BABE! JUST TAKE A PIC OF ME TOWERING THESE SMALL ROCKS!" Rune boisterously lagged as he let the drink do its worst to him, making him surge taller and taller, his muscles bulging and growing to accommodate his new height of 4000 feet tall, and yet the power of that magical drink still surge around him, washing him such delight and arousal as he felt himself grow, shooting up a hundreds of feet more.

Finn could only stare in awe, his libido as big as his titanic canine as Rune outgrew both mountains like it was nothing, peaks only reaching the titan's waist. That little sketch of his earlier was realized by that magical drink and more as the canine kept on surging, his massive, muscled body casting a shadow even from here, all the way behind him as he flexed his muscles, his body creaking for every movement of his titanic body as Finn kept on stroking his dick.

Still high from his growth, the titanic Rune squatted down, enjoying the way his growth kept on going and going, eyeing the two mountains as he was close to surpassing them even like this. He had to have doubled his height already, and he could feel the power just starting to wane. He chuckled, to think that he would be this tall already.

"Fuck me...Rune..."

His ear twitched as he turned to look for the familiar cliff, looking like a mere step from his point of view. Rune could only laugh as he began his trek towards his miniscule little fox, trying to make gentle steps to ensure the earth won't rumble that much against his weight.

Finn could only stumble backwards, landing on his ass as the titan scooted closer. Still squatted, his balls and erect cock swinging wildly until those massive, mall-sized balls were now in front of him, or at least the bottom part of those nuts are. He had to look away, tilting his neck until it hurts to even see the titan's face, grinning at him, obviously enjoying this as much as he does.

"Hey there, babe." Rune rumbled softly, enjoying the feeling of the earth quaking due to him just whispering. He hovered an extremely massive paw over him and gawked at how much space his paw could occupy; it covered more than just the campsite, going further into the woods. "Like my paw? Grew it myself!"

Finn whimpered at the sight of that massive paw covering the sky, the paw looks fit to destroy an entire city block or two so easily, and from here he could see that it was still inching wider, growing bigger. The orange fox felt his balls lurch, too tired already, but he was so aroused, he wanted to go in and just touch it, to touch his giant despite their impossible size difference.

And it was as if Rune could hear his thoughts, because in one impossible quick movement, the titan held his paw up, level with the cliff. "Hop in, babe. Don't wanna lose you down there!"

Finn, however, was simply admiring the size of the palm in front of him. No, he realized he was looking at Rune's finger, the paw pad on it was so expansive that one could build a shopping center on it. The vulpine whined as he watched the finger expand and surge in size, bumping slightly against the cliff, pushing against it as it shook the earth beneath him. That was his cue to finally accept the giant's invitation.

Rune's chuckles turned into boisterous laughter when he saw that tiny, tiny down almost rush towards his finger, feeling Finn's negligible weight landing on his paws. The giant, still-growing rottie twitched, feeling Finn's small steps despite the size difference as he watched Finn get closer to his palm before closing his hand a bit. "Hold on tight, Finn!"

The fox, a bit breathless, never got the chance to fully rest and admire the expansive paw bean he was on it as he the paw he was on slowly moved, closer and closer to the massive hound's body, going around the towering cock that, while still proportional to Rune's old size, was so massive that it looked taller than a fucking tower, before Finn was now in front of Rune's midsection.

It wasn't long before the wall of abdominals beheld him like it was the Wall of China, except even more impressive and even more beautiful; the brown pelt stretched so far to the sky as those pecs of Rune's loomed over, growing closer and closer to the sun as Rune's torso surged, those pecs seemed so far away now from his position.

And then, the dog shuffled a bit, his entire body moving as Finn tried to figure out what was Rune's plan. It took a while for him to know that Rune sat down, his ass causing a massive quake despite being gentle, before slowly leaning down, all the way till his muscled back hit the ground. He heard the giant chuckle as Finn was finally out of the titanic dog's shadow and at this point Finn had his eyes wide as he beheld the scenery in front of him.

It was like what he saw earlier, except instead of greens of the trees, a river in between, and two towering mountains standing side by side, it was of Rune's massive, ever-expansive torso. The brown pelt of his made up most of Finn's view, Rune's hilly abs surging upward for every breath, a long canyon dividing the two sides, running deep all the way to those massive muscle mounds that made the scenery even more beautiful and arousing. Rune's pecs stood tall, despite laying down, something that even from his normal size was something that the fox enjoyed. Now, it stood taller, casting a shadow on the brown-furred field in front of him, a massive canyon in between.

And what was so amazing was that the growth was still happening. It was slower, the growth finally subsiding, but the vulpine could still feel the ground stretch under his feet, the brown pelt expanding before his very eyes.

"Enjoying the scenery, babe?"

And then out comes Rune's head, slowly peeking in between those mounds, a literal massive smile on his face, a bit strained due to his continuous growth. Finn could only breathe, the sight was simply mesmerizing as the palm he was on gently descended. "Hope you're fine playing around with my abs. I don't think you could explore anything else." Rune chuckled, the fox having to hold his ground.

And Finn did want to, he wanted to fully explore Rune's expansive midsection, to feel absolutely tiny against just a small part of him, to feel so incredibly miniscule against his giant lover. He was practically salivating when the titanic canine gently slid him down, very careful with his lover as he finally felt the short, brown fur and the strong muscles of his titanic Rune, staring at the tall hill of abdominals just around him.

The vulpine can't help it, he wanted to go in front of those mounds of muscle, to let him feel insignificant, but one step of his made the ground he was walking on shudder, Rune moaning so loudly.

"Shit, Finn, was that you walking?" Rune moaned, a paw stroking his massive cock, the massive towering shaft behind Finn standing tall. "I...fuck, I could feel your steps. You're so small but...shit, it's enough..."

Finn looked at his feet, curling his toes before stepping hard on the ground and was rewarded with his titanic dog moaning, a massive drop pre falling a few meters to his side. The fox turned around, marveling at the sight of that towering cock gushing gallons of pre.

The fox's tail swished, his mind trying to catch up with what's happening before grinning. "Is that so, my big dog~?" He teased, not expecting to have the chance to tease Rune considering their size difference. He started massaging the ground with his feet, slowly and deliberately pressing his paw pads, making sure his ministrations are to be felt. The titanic dog could only thrash around, his limbs flailing as he moaned for every movement the fox made.

"Shit! Finn, please do more..!" The titan groveled, enjoying the sensations of his miniscule fox's tiny steps. He didn't think the drink would make him so sensitive to Finn's little actions, but it was so worth it either way. "S-step on me more, please!"

The fox chuckled. "Well, it is my birthday." Finn took deliberately hard steps all around, slowly walking towards a jutting hill-like ab in particular; each step made his cock hard as ever. "Let's enjoy this gift together, Rune!"

And Rune was enjoying it, so much more than Finn could ever realize as the cocky titan was now at the mercy of his miniscule Finn; those tiny, tiny feet applying even the smallest of pressure on his pelt was so incredibly stimulating. The titan could only groan in pleasure, so much pre gushing out of his cock head as he slowly stroked his cock, his head in a constant daze as the unrelenting growth, mixed with Finn's footfalls washed his mind in pure bliss.

Finn, however, kept on walking, his steps as heavy as he could, but sometimes he would falter, due to the realization that this entire field around him was just a small part of Rune made him horny, made him want more. His earlier dream of Rune becoming bigger than the planet was still present in him.

He wanted, at this point, needed Rune to outgrow the Earth, see him play with it with his mighty, country-wide paws as he loomed over it with a smile on his face.

The horny vulpine locked his lips, salivating at the mere thought of it all. "Shit...Rune...I want you to..."

He idly turned his head to the side, and a sight of something that shouldn't be there made him stop on his tracks, his mind reeling in different directions as, right there in front was...

"Is that...the bag?"

It was. The tote bag was there. The fox had to rub his eyes a few times to finally realize that it was truly there, his mind trying to piece out how it ended up here on Rune's vast abdomen. The fox walked towards it, the dog moaning in the background, slightly forgotten, because if he was right, there should still be...

And there it was; inside the bag were two bottles of that growth potion that made Rune the titan that he is today, and these two bottles were the key to making Rune even grander than life, the fox cock spurting pre with that thought, the warning from earlier coming back.

"Exponential...shit, this could make him..." Finn's mind was running on that singular thought, the need for more of his titan, more of Rune to be smothered by a moon-sized finger, for him to be so gentle to him while he teased him with his steps, their size difference off the charts.

He wanted it, craved it, even.

But how? Rune's mouth was at least half a mile away from here, maybe even more. If only he had his car, he thought, as if the magic that teleported the bag here would teleported the car as well. Instead, the bottles inside the bag flashed a bit, just enough for the fox to see. He quirked a brow, the backdrop of the dog moaning continued all around him as he grabbed one and...

'This powerful concoction can also be poured all over the body, a multi-purpose concoction!'

"That...certainly wasn't there before." Finn mumbled, pretty sure that he read all of the relevant warnings earlier, but this new revelation about the drink made him think, just a bit before grinning.

Ah, but first.

"Rune!" he screamed, hoping he could hear him despite the city-wide size difference in between. Fortunately, Rune responded in kind with a grin, the vulpine grinning. "You want to be even taller?"

"H-huh?" Rune let out, heaving as he felt his erection get even harder at the thought of becoming even bigger than he was right now. He was already thousands of feet tall, an entire city could be made on top of his body and yet...

"Rune??! Do you want to be even larger?! Even taller?!"

He wanted it, he craved it even. To be an even bigger dog for his already tiny fox, to be even titanic that he was before. To be bigger than the earth for his little Finn.

"Yeah...fuck, Finn I would like to..." He rumbled, his cock twitching erratically. "FUCK, MAKE ME GROW, FINN! TURN ME EVEN BIGGER!"

That was all Finn needed as the vulpine hurriedly opened the two bottles and poured it all in front of him.

"God, I hope this works." Finn saw all of that magic drink pour down, pooling in front of him. He hadn't had time to see the puddle of that drink disappearing when the ground underneath rumbled ominously, the moans of his titanic dog turned into full-on howling.

"IT'S...IT'S STARTING!!"

Finn held on the ground as he and his titanic rottie anticipated the upcoming growth, expecting the rottie to grow so immense.

But never in their lives expected the massive spurt that happened as Rune grew 5000 feet in a blink of an eye, practically double in height. The tiny fox had to hold on for his life as the land beneath him stretched astronomically, the hills of abs stretching to become more than mountains, becoming entire plateaus of muscle as Rune kept on growing at a much faster rate than ever. His paws held on, his body pressed against the solid ground that was Rune's stretching midsection, humping the ground, moaning as the growth kept on growing.

Rune wasn't doing any better; the earlier growths were already too stimulating, but this one was giving him pure, unbridled ecstasy. The rate of his growth was staggering to think of. Miles of land being crushed by his broad, muscled back as his height doubled, tripled, hell, quadrupled in seconds. He could only helplessly flex his free arm, all while jacking himself off as the sensation of his miniscule fox somehow multiplied all the same, moaning for every humping the fox kept doing on him.

The pleasure was so much that he had to grab onto the ground below him, carrying a chunk of land in his free paw as he kept on stroking his member, the dog so close to the edge of orgasm. He titled his head, curious about the chunk of land on his paw and smiled as he saw something that made him laugh.

It was one of the two mountains; the towering mountain that looked impossible big was now smaller than his paw and more. This entire sight kept him on the edge as he laughed and screamed, his deep voice traveling for miles. "MORE! I WANT MORE!"

The dog's height kept rising, now only measured by miles, and was increasing at such an insane rate. 50, 100, 400 miles of hunky dog and the growth kept on going, the titan was becoming more of an absolute god, his growth showed no signs of stopping as all Rune and Finn could do was enjoy the sights.

And that's what they did. Finn could only moan loudly as he turned around, his back against a tiny part of Rune as he felt himself being thrown to the ground from the speed of his titan's growth. It was all so much, and he was liking it. He could only imagine it all from here, but it was enough, as Finn kept on jacking off, a free paw massaging what he could of the titan, hoping he could feel it.

And he could, judging from the increasing noises from the titan. The pain had subsided, and all he could feel was intense pleasure from Finn's tiny touches. He could just FEEL that tiny, almost atom-sized paw massaging his body, sending such pleasurable shocks that fired his nerves and made him incredibly needy for more. His tongue was out as even the clouds passed by, now hovering below him as he outgrew the entire country, close to becoming a continent of his own and was still not stopping. He could feel the curvature of the planet against his muscled back, miles upon miles of land being conquered by his growing size and still...still, he was growing.

"FUCK!" Rune moaned as his balls, now the size of smaller countries, lurched before landing on the ground hard, who knows how many properties he had destroyed by that one action. He was so huge that every single action of his caused destruction, his old role play session with his tiny fox finally becoming real. The dog could only whine pathetically before moaning so loud that it could be heard from space as Finn started moving around, those tiny steps back at it again.

"FINN! FUCK! PLEASE, MORE! Rune begged, and Finn would gladly do so for his titanic, planet-sized canine as he jumped up, landing harshly on his feet and was rewarded with a howl of intense pleasure coming from the titan. More and more this goes on the growth, the sensations, all of it sending Rune closer and closer to the very edge until...!

With one intensely loud howl, the canine finally came, a thick blast of cum fired at the very expanse of space itself with a lot more to go as the planetary canine arched his back, making Finn feel the coldness of space slightly before going down.

Finn, meanwhile, could only stare at the almost-fantastical sight in front of him. It was already a miracle that he could breathe easily near the stratosphere, but seeing those incredibly thick cumshots float in space, some falling down and landing on the Rune's hunky body was a wonder of its own as he finished jerking himself off, cumming right then and there; the amount of cum he released so pitiful against the rottie's output, but it was fine. Extremely fine.

The fox then laid down on the ground, another moan from the planet-size dog. He could only imagine the size of his titanic rottie, but it was enough for him.

Minutes flew by and the canine's orgasm finally subsided. The space in front of the two was filled with floating blobs of thick cum, each one bigger than the moon, probably even bigger. The fox reached his hand out, fully relaxed at the sight of those stars before something immensely large blocked his view.

"How's...how's my tiny, tiny birthday boy?" Rune cooed as he gently, ever so gently petted the fox, tiredly laughing at how intense their size difference was. "Sorry, Finn. I'm so tired, I..."

"S'okay, Rune." Finn said as he looked above, the moon-sized fingertip pressing gently against his snout before Rune let his hand away. "Kinda tired, too."

Rune had to laugh as he put his hands behind his head, now focusing on the feeling of the planet against his lower back. He grinned. "Hey Finn."

"Hmm?"

"Guess what?"

Finn chuckled, already having an idea on what the dog would say. That doesn't mean he wasn't excited to hear it outright, though. "What is it, hun?"

"I'm bigger than the planet now." And it was true, most of his hunky body was outside the planet now, hanging precariously while a portion of his lower back cradled against the miniscule orb of land. He looked around and saw the moon just floating by, and laughed when he compared it to his paw, looking so small against his grasp. "Can even reach the moon from here. With how big I am, you could build an entire civilization in just my pecs."

"Really now?" Finn chuckled, still tired but clearly enjoying this.

"Yup! I'm gonna dedicate it to you, too! The Nation of Finn." Rune excitedly exclaimed, motioning his hands around to exaggerate, his lips curling into a smile as he heard his miniscule fox laughing. "The citizens will worship their titan and his beloved, ever-so handsome fox. Why, I'm gonna demand some festivals in your honor! Nothing less for my tiny fox."

The vulpine could only shake his head, grinning as the dog continued to talk about his new doctrines as the new mighty and hunky planet Rune. The fox can't help but feel tired, yawning as he felt himself curl against the soft, warm ground.

The last thing he felt were the soft strokes of a fingertip so extremely titanic that it could crush entire countries, and yet ever so gentle when it comes to him. The giant rumbled low, whispering to him in such soft tones as the both of them felt the pangs of tiredness overtake them.

"Happy birthday...Finn."

"Thanks...Rune..."

***

The cold breeze of the afternoon winds blew past him as he beheld the scenery in front of him; the expansive forest, filled with towering trees, a river that snakes in the middle of it, dividing the forested lands, and two towering mountains that loomed all over it. The sight was a perfect definition of an untouched paradise.

A funny thought, considering what just happened earlier.

Finn chuckled, playing around with an empty bottle, leaning on the railing with a content smile. The cold breeze brushed past him, thankful that he had his jacket and pants back on, surprisingly clean. It wasn't long before he brought the bottle up to his face, reading a particular entry on the description.

'Note: Any and all destruction caused by the drinker during its effects will be restored to its previous state.'

"This was certainly not there earlier, either." He mused, looking over the bottle to look for other details he quote unquote missed. It wasn't long before a pair of strong arms wrapped around his waist, a head nuzzling against his back, and Finn chuckled before turning around.

Looking down, he saw the face of his hunky hound, back to his original height, as if nothing ever happened. Finn smiled, the sensation of looking down at his lover felt both nostalgic and weird considering he saw him become so titanic, bigger than the planet, but here he is, in the flesh and properly clothed.

Rune was like this for a while, and it was starting to tickle the vulpine as they both laughed, enjoying each other's company. Finn brushed a paw against the hunky canine's cheek. "What's wrong, Rune? You're a bit more touchy-feely today..."

"Just missed hugging ya'! It wasn't the same when I was so huge..." Rune cooed as he hugged his beloved tighter. Finn accepted his fate for the unforeseen future as he stroked Rune between his ears. Well, that was true enough. It was nice being petted by a finger the size of the moon, but this, this entire thing was nice. Rune sighed contently, kissing Finn on the cheek. "If I were to buy some of those again, I'll probably just drink a bottle or two at a time."

"Aww, not gonna try hugging me as a ten thousand foot tall giant?" Finn teased before screaming when Rune easily lifted him up, swinging him around gently as they both laughed. Finn was kept in the air for a few minutes before Rune finally let him go.

"Well, if my tall birthday boy wanted that, then who am I to say no?" Rune said with a grin, before frowning. "Though, that means I have to talk to that wolf-dragon again..."

"Is he really that bad?" Finn asked as the couple walked towards their car. "I mean, the drink works, he can't be that bad, can he?"

"He kinda is...? He just has this air of..." Rune flailed his arms around, as if that was enough of an explanation. "I have to take that free sample of his to make sure it worked before buying a six-pack." Rune snickered before elbowing his tall fox gently. "It was worth it though, right?"

"Really worth it." The orange fox smiled before kissing Rune in the cheek. "Thanks for the gift, hun." And after a few minutes of loving silence. "I love you, Rune."

Rune responded with a kiss of his own before chuckling. "Love you too, Finn." The dog stepped back a bit with a wide smile on his face. "Now, lemme just check up on the car. Hopefully I didn't break it earlier."

Before Finn could even say something about that, the canine ran towards their vehicle, the canine still had a lot of energy despite what just happened. "Haah, how does he get all that energy from?" He mused as he turned back to the scenic mountain view. He's going to miss this place.

Still, he was wondering about that wolf-dragon his lover mentioned. Was he in the city? Maybe he could buy something to surprise Rune for his birthday soo-

"Hold on." Finn stopped in his tracks, noticing something wrong with Rune's story. "He bought...six bottles, right? But there were only four in the bag, plus the one he drank earlier..."

The vulpine crossed his arms and focused, not noticing what the dog was actually doing. "He said he tested it when he bought it...no, that was a free sample he said. So where's the sixth-?"

His ears swiveled when he heard Rune sigh, as if he just...drank...something...

Finn's bushy tail swayed around, his fur bristling as he slowly turned around, only to find Rune smirking, an empty bottle in his paw. "So..." Rune started, a sly grin on his handsome face. "Been thinking. Kinda in a mood to have a little walk. Just you, me and..."

Rune visibly grew half a foot taller, his clothes stretching up once more before slapping the roof of the car, a wide grin on his face. "...and this toy I found. You in?"

Finn could only stand there for a while, before laughing and running towards his little Rune-no, he was already taller than him. The fox immediately got carried by such strong arms, while Rune held his smirk, wiggling his brows before laughing loudly, shooting up a few feet taller before kissing his fox. "Happy birthday, babe. Love you."

"L-love you too, Rune." Finn mumbled as the rottie shot up past 20 feet tall, feeling smaller against his powerful, giant husband who carried him to his shoulder. Once Finn was seated properly, Rune picked up the car with ease with his two arms.

"Welp! Time to go home! You ready, babe?"

Finn could only stare at those green eyes, that handsome face, the feeling of elation keeping him warm as he nodded. "I gotta make up to you on your birthday. Remind me next time."

Rune could only smile as he nuzzled against the fox, his head larger than Finn's entire body. "Aww, babe that's so sweet!" The giant, growing rottie started walking, his clothes already torn apart. "And sure! Are you gonna buy from that guy, too? Sketchy as he is, he's got a lot of drinks in his stall that you might like. Like there's this one drink that would make you really muscular! As in, exploding with so much muscle! Though, now that I think about it that might not be your style...unless you make ME drink it? I mean, I wouldn't mind that! I wanna feel how big my muscles could get, too! Ooh, or maybe the..."

The giant, growing canine continued to talk, all while outgrowing the entire forest. Finn could only chuckle as he led his eyes forward, enjoying the scenery, his line of vision rising as the rottie grew past 50 feet tall.

Rune was right. This was the best birthday gift he ever had, and he knew, he just knew that his little Rune would try and outdo himself next year. He always has.

And Finn can't wait for it.
