Gift Exchange

In a relatively quiet suburban neighborhood, a white ferret sat at his desk while trying to confirm his plans for the evening with a restaurant that had been booked months in advance. He wanted the whole night to go off without a hitch; his fox was worth the extra effort to get into the fancy restaurant. “Uh huh… yes definitely. Great, 8’ o clock then. Thank you very much,” Mathis finished as he set down the phone receiver. He relaxed in his chair with his long tail flicking across the carpet, mind racing as he tried to make sure he hadn’t forgotten anything.

The restaurant wasn’t the only thing planned for the night either. Mathis eyed the small box at the edge of his desk and smiled. A gift for the fox who’d found his way into his life. But small gifts could be just as special as big ones, as the both of them knew very well. It was sure to make their date more interesting. Zev always said it would be good for the both of them to expand their horizons, trying new things. And this would definitely be something new for the fox.

What he didn’t know was that Zev had his own special plan for the evening. Gifts were meant to be shared mutually after all. Zev’s ferret boyfriend wasn’t aware that he knew about the gift already. But foxes always know. That’s part of their devious nature. The rest of their nature revolves around floofiness and chickens. But mostly deviousness.

Zev walked up to the door and rang the bell, hiding one hand behind his back with a strangely shaped package. He nearly dropped it though as the door swung open and a ferret bounded forward. He was caught in a bear hug that he could only half return still holding tight to that gift. But he was plenty able to return the kiss that followed.

“Hey there dookzilla,” Zev said cheerily.

“Ready for our date?”

“Well not quite,” Zev said with a grin. “I’ve got a-“

“A gift?” Mathis finished, reaching off to the side of the door way and bringing back a package of his own. “I’m never going to surprise you am I?”

“Not so long as you’re with a fox.”

Mathis chuckled and traded gifts with his fox. They each tore at the wrapping paper, Zev finishing first with the tiny package. He pulled off the top of the box and removed a small necklace with a silver chain and purple crystal dangling from the middle. The fox ooo’ed and ahh’ed, running his hand over the crystal’s surface to polish it lightly.

“Where did you get this anyway? It looks really professional. Expensive too,” Zev asked as he hooked the clasp into the necklace’s latch around the back of his neck.

The ferret finished unwrapping his own gift, pointing the ray gun around at various items and making ‘Pew’ noises. “Oh a friend helped me find it,” he replied. “Your turn now. Where did you get this?”

“A friend, just like you. It’s a size changing ray in case you hadn’t guessed by the way. Something to help you with your fun. It turns into a belt too for more portability. Just press that little button on the handle.” Once Zev had helped his boyfriend put on the belt-ray-gun he planted another smooch on Mathis’s cheek. They hadn’t been going out together for that long yet so to some it might seem the gift giving was a little premature. But Zev hadn’t been happier in a long time. Everything seemed to be coming together all at once, between work and a boyfriend and a new place to live. Plus if the present actually worked the way his scientist friend said it would, this could make for a very fun night.

Mathis brought his hand to the necklace Zev wore and smiled. “It looked nice before in the box, but it looks even better on you,” he said. “Wanna see what else it does?” He didn’t even wait for a response though, instead applying pressure to the crystal which took on a faint glow.

Zev could feel warmth pass from the crystal through the core of his body and spread out to his limbs. He was only mildly familiar with the specifics of magic, but could tell from the feeling this was definitely magical energy. Once its effects kicked in he didn’t need to be an expert to know what the necklace was enchanted to do. His shoes started tightening around his feet and the dress shirt he had put on for their date dug into his muscular arms uncomfortably. Zev didn’t want to damage that shirt though so he started fumbling with the buttons trying to remove it in time. He didn’t end up destroying the entire thing, but some seams would definitely need to be repaired.

The shoes didn’t fare quite as well though. They tore off the body of their now twice as tall owner and lay in a heap at his paws. But something else strange had happened thanks to this gift. Most of his muscle, which he’d proudly been working on for the past several years, had wasted away somehow leaving him a twinkish version of his normally body builder self. Thankfully this did mean his pants hadn’t been entirely destroyed. Between the loss of mass at his calves and thighs and their increase in height, it didn’t feel like there was a major difference in its tightness. But they did feel more like a pair of shorts than the dress pants he’d arrived wearing.

“Where did all my muscles go Mat?”

The ferret hugged his fox, head only coming up to navel height. “It’s only temporary, promise. You’re the one who kept saying we need to try different sorts of growth. So now you get to try out my body type instead of being bulky fox.”

Zev ran a hand down his side where he used to have that distinct V-shaped torso. “I feel naked without my muscles though. It’s… different.”

“Are you sure you don’t feel naked for other reasons?” Mathis chuckled as Zev covered himself; his boxers and pants hadn’t come off but definitely didn’t look like they would fit him anymore. The two of them headed indoors to get the much taller between them changed into better fitting clothes. Zev bumped his head on the door frame though. It would still take some work to learn to duck under doors rather than having to squeeze his muscles between them.

The ferret had plenty of clothes for his boyfriend. Being a size changer meant always being prepared for any height. Zev’s ears flicked on the ceiling as he tried to get a good look at himself in the mirror and blushed when he realized that from his chest up he couldn’t be seen.

“You look great Zev. Shaped a little more like the stereotypical fox now,” Mathis teased.

Zev cocked an eyebrow and replied, “Oh do I now? You already know what I think of those stereotypes. Are you just trying to get my goat now?”

“Who me? Never.”

“Well if I’m being more stereotypical now, guess I shouldn’t wait to put my deviousness in motion. Foxes always have plans after all,” Zev said as he got down on his knees. Mathis wasn’t prepared for the passionate kiss he received, and it made him a little weak in the knees to have that much fox to kiss. But he also wasn’t paying attention to Zev’s hand fumbling with the ray-gun-belt.

Once he realized what was going on it was too late. Something clicked as though a trigger had been pulled and Mathis’s vision was filled with white light for an instant. The ferret closed and shielded his eyes with his hands. What the heck was that about? What an obnoxious way to cause growth. It took several seconds of blinking and readjusting his eyes before Mathis could really look over his body again. At that point the changes had begun, his clothes slowly shredding around his muscles.

He lifted an arm to try getting a better look at the seams coming apart along his sides. But lifting that arm only made it worse as his bulging shoulder muscles pulled the fabric tighter against his arm, delts and traps forcing the dress shirt to its limit. Worse still was the front of his shirt where the buttons popped off as his pecs thickened monstrously. The shirt split straight down the front to reveal hardened six pack abs above a set of legs that his pants struggled to contain. He added pounds upon pounds of muscle and was left wearing nothing but a pair of boxers stretched skin tight. He’d gone from a wiggly twig to Hercuferret in such a short time that he was still trying to register all the changes.

“What? Just muscle?” he asked, feeling up his arm tentatively. He felt those biceps, his biceps, big as a grapefruit tense under his fingers and heard the ripping of fabric as white fur peeked out. “I mean it feels pretty nice. But where’s the height?”

“That belt isn’t just meant for muscle. It can change other parts of you too. But since we’re ‘trying other sorts of growth’ in your own words, this is what you get. And don’t mess with the belt, ferret paws. You don’t know how it works,” Zev said, amending his words once he saw those Mathis’s hands start fiddling with the belt. It was only natural for a ferret to want to mess with something that shiny especially after he knew what sorts of fun it could cause.

The mustelid’s tail wiggled back and forth, deep in thought. “I guess it couldn’t hurt to try this for a while. You can look more stereotypical and I’ll be as far away from a ferret body type as I possibly could be. Just hope that there are some of your leftover clothes around the house I can use.” He tried to make his way back to the bedroom but found himself suddenly caught in the doorway. A bonk on the head he could handle, but being too wide to walk through a door? That was new.

“A little help please?”

---

The two of them drove downtown after no small amount of fighting and squeezing to get inside their car. Mathis joked about how small Zev’s clothes felt. The belt had been a little too effective but now he could brag that he was even bigger than the vulpine’s normal size.

“Hmmph. Foxes should be buffer,” Zev mumbled. He ended up handling the driving though. His normally thin mustelid boyfriend wasn’t used to having his bulk rubbing up against each set of muscles and each movement threatened to tear his clothing. It was definitely in both their interest for the thinner fox to take control despite his difficulty pushing the pedals comfortably as he crouched over the steering wheel.

The waiter did his best to cater to the two guests but was clearly distracted by their overwhelming size. He wasn’t the only one either. Guests all over the restaurant whispered and stared at the two massive furs as they tried to enjoy their evening out. Any other night it would’ve made more sense for the whispering to be due to the two of them holding hands. Zev found himself using two chairs to sit on and had to avoid the overhead lamp that lit up their table, while Mathis used the booth side of the seating choices because he wasn’t sure a regular chair could hold up his weight. The two of them smiled at each other. Neither was any stranger to extra attention due to their size. They each ordered an obscene amount of food to make sure they would have energy to power their newly grown bodies.

Part way through his second plate of chicken Zev looked down at the gift hanging from his neck. It perfectly complimented the white dress shirt and purple tie combo he wore that evening. It was such a thoughtful gift he decided that he would need to think of another way to make it up to his lover sometime that evening. He placed a paw over the sapphire.

“Thank you for the evening and the gift Mat,” he said while leaning over to plant a smooch on top of the ferret’s head. “It was so sweet of you to- ouch!” His heartfelt declaration of affection was cut short when he knocked his head against the lamp again while leaning back up. Mathis chuckled and held his boyfriend’s empty hand. More accurately he held about half of his boyfriend’s hand because it was so much larger than his own.

“It was nothing. Just a gift for a very special fox. Wanted to show I cared somehow,” he replied.

The crystal underneath Zev’s hand heated up again, pleasantly keeping his palm warm. He hummed appreciatively as the soothing energy passed through his body. “And I like that the crystal stays warm even after the growth. Think that I’ll keep it with me more often. It feels really nice.”

Mathis paused with his fork halfway to his mouth. “Still warm? That’s funny. My friend said it was only a one time use.” He watched a button fly away from the fox’s dress pants and realized that it most certainly wasn’t one time use. Zev was growing again, but that could turn out really badly indoors!

Zev had noticed the changes as well as his eyesight changed from looking up at the ceiling lamp to looking down at it. For the second time that day he felt his clothes getting more constricting all across his body, tightening all over his arms and legs. The shirt started to ride up to show his stomach and the tie on his neck felt dangerously constricting. This was worse than just an inconvenience though; in addition to nearly strangling himself with his clothes, he had the added issue of being in public. He struggled with the buttons and tie to loosen as much as he could without removing anything, but was too late to avoid ripping his pants nearly all the way up the side of his legs. He sped up his work to try saving his modesty and soon found another problem to deal with as the lights in the ceiling got warmer and warmer. He didn’t realize just what that might mean until he knocked a panel loose from the ceiling with his head. So now, hunched over and barely making due with his childishly undersized clothing, Zev blushed heavily and tried to calm down the other patrons with a smile and a wave. The warmth from his necklace decreased slowly as he reached double his previous height.

“Think you might need to talk to your friend later. They seem to have a strange definition of ‘one time use,’ don’t you think?” Zev said as both chairs he was carefully perched on top of creaked and collapsed beneath his fuzzy rump. He yelped as his tail connected with the floor and again when his head hit the ceiling as he reflexively sat up straight. His ears splayed out as he rubbed the tender spot on top of his head. Even while sitting down he’d managed to reach up to the roof of the 10 foot tall room.

“We can still finish off our dinner though I think. You’re not too big yet,” Mathis said, trying to make light of a bad situation. The restaurant staff was a little more worried about the sudden change in size and damage to their property though. The manager, wringing his hands the whole time, politely asked them to leave. The food is on the house, no need to worry, but you see this restaurant isn’t built to handle patrons of your size you see, and you’ve been very polite, but please leave, thank you for your business and come again if you get smaller. Zev got the feeling the manager wanted to be a little more aggressive than that but foxes could be a little more intimidating now that he’d gotten even taller.

Mathis on the other hand was tempted to throw around his new found bulk to convince the manager to let them stay. After all, leaving now would put a serious damper on their date. But he decided against it in the end. As he stood up he noticed the clothes were tighter than when he’d sat down at the start of dinner. And it was a bit difficult to tell but it seemed there was a small height change as well. Something was definitely going wrong with him now too. He decided to only bring it up once they left the restaurant though, which proved a more difficult ordeal as he shimmied and struggled to fit through the now much more constricting doorway.

Scooting out with a cartoonish ‘Pop,’ the ferret breathed much easier. He thought the sound was simply from his muscles pushing up against the frame but with a shine of bright light he realized something else had happened too. The belt had caught the door on his way out and somehow had been triggered yet again.

“Shoot, not more!” Mathis squeaked as he bloomped up to even further sizes. He’d never fit through that doorway a second time, widening his stance and shoulders to nearly twice their previous width and thickening all over so much that even squeezing through a door sideways wouldn’t work. The dress clothing popped off his body like a cork from a bottle, leaving only his strained boxer briefs cradling an enormous ferret package. And it really was enormous now. The bulge he was sporting looked as though a beach ball was shoved in front of his pelvis. He shouldn’t have been surprised by the change considering Zev was liable to cause changes like this; he just hadn’t noticed anything from the first growth spurt. But being out in public looking this lewd, having to deal with the considerable sway of his briefs now, was enough to make even a seasoned size shifter like Mathis blush. He brought a finger against the blue, tight fabric to make sure it was real. It wasn’t as easy to maneuver his arms now, fighting to bend them as the muscle rubbed against each other at every chance. Once his hand connected though, the ferret moaned involuntarily and his member stirred to life. A bigger size and more sensitive too? Definitely up Zev’s alley. Mathis forced himself to not press his luck any further with this new endowment (at least not in public).

“I don’t think we’re going to be able to finish our date at this point, foxy,” he mused.

“What? You were still planning to try finishing? I gave up on that already,” Zev replied as the sound of crunching metal split the night air. Mathis turned to see his date sitting on top of the car they had driven to downtown. Well, what was left of it at least. Zev had thoroughly pummeled it under his rump, a single tire rolling away from the wreck. The fox had definitely grown yet again. The whole car fit easily underneath him, just the same as the chair in the restaurant.

Zev gave a cheeky smile and grabbed the ferret for a hug. “The growing still hasn’t stopped you know. So maybe this should be our date instead. Wanna get huge with me?” Zev punctuated his proposal with a peck on top of the ferret’s head and a tight snuggle against a fox chest as tall as the Mathis’s whole body. Once the torrent of dooks and squirms of happiness slowed, Mathis hugged his bulging arms around the fox in return.

“I thought you’d never ask!” the ferret said as he reached up to grab the necklace he’d gifted to his boyfriend. He squeezed as tightly as he could on that crystal; increased pressure was supposed to speed its effects according to his friend. But maybe he wasn’t quite used to his own strength yet as he felt the crystal yield under his hand. He saw a single crack from top to bottom in its surface, and a bright purple light peeking through that crack. That wasn’t supposed to happen.

Meanwhile Zev was fiddling away at the controls of his boyfriend’s belt. Wearing nothing but boxer briefs and a belt… quite the interesting fashion statement. That two-piece outfit might be broken down to just one-piece soon if that bulge had anything to say about it though. Zev couldn’t help himself as he gently groped at it with his free hand. The ferret package throbbed gently as he did, hardening under the careful grip of the dexterous vulpine fingers. But this was definitely not the right size yet. He needed to really go for broke and put this bulge to shame. Either by muscle or bulge, Zev was determined to make movement a non-option for Mathis. Maybe even through both options. But through a combination of his distraction at the ferret’s sexiness, and the sudden growth spurt from his now fractured crystal, Zev’s hand fumbled with the controls of the belt. Several dials turned and a few buttons ripped from their sockets. Then the belt started blinking and buzzing as though charging up for something major. That definitely wasn’t supposed to happen either.

They looked down at their own gifts, then back at each other again. And with grins on their faces, the growth started.

After five minutes, Mathis was showing off by picking up entire buildings. Entire gyms detached from their cement flooring and were treated like weights for benchpressing. Soon after that, only used as barbells for curls with one in each hand. Once those didn’t even register as actual weights for him though the ferret smirked and moved on to even bigger buildings. Moving to get those buildings was getting harder now thanks to the enormous bulge between his legs. It dragged along the ground as he walked, almost waddling by now as it pushed forward to the length of a semi-truck. And that was when he was still flaccid.

After ten minutes Zev was leaning up against the tallest building in the city, half as tall as the quadruple-digits tall skyscraper. The super stretchy speedos he normally wore stretched skin tight against his legs and bulge, leaving nothing to the imagination of the people inside. He struck a few body building poses. Oh wait, one needed muscles to pull off something like that. He blushed and instead waved at those inside, even as his head passed floor after floor of the high rise building. Following after his head was a pair of speedos. And once those speedos had reached the top floor, the fox snickered and dropped his package on top of the building. Twice as tall as the biggest skyscraper in the city, tea bagging it without any difficulty… a pretty good start.

Twenty minutes into the growthstravaganza the ferret was finally looking more like a macro. Perhaps to compensate for all his bulk he’d begun to get taller all over. Most of his mass had been diverted to his beef and balls but now he could look over the tops of some taller buildings in the city at least. A lot of his height was concentrated in his package now though; it had gotten large enough to push him off his feet, draping his body across the shaft while his balls held his legs aloft. This was the only way he was able to pleasure himself anymore. His hands rubbed across any surface he could, even as his biceps, triceps, and delts made the rest of his arm movement impossible. His arms were pushed straight out to their side and most of his pleasure came from bucking his hips against the ground. Breathing heavily, Mathis could feel himself getting close… just as a large shadow distracted him as the landscape darkened. Without breaking his rhythm the hardened ferret looked up to see what was going on; or rather, looked as far as he could manage with his pecs and back muscles making head movement that much tougher. Above, the sky had turned black and the clouds were gone. Instead the heavens were shaped like a single paw. And far beyond that paw, a fox’s smiling face winked at Mathis. Those godly toes wiggled to tease the ferret, who couldn’t believe his eyes. Zev had gotten so big, so quickly! And as a toe accidentally knocked the radio tower off the top of a skyscraper, Mathis eeped in surprise. That dang fox was teasing him… he knew about his thing for feet clearly. That alone was enough to send him over the edge, blasting out a catastrophic flood of cum into the streets.

---

Mathis sighed as Zev held him against his chest. More specifically, between his pecs. He was the size of a stuffed animal compared to the mega fox; a bulgey, muscled, obscenely well-endowed stuffed animal, but still. It was a good thing Zev was holding him up now because there was no way his limbs could move anymore. He would’ve been fated to remain immobile from his own bulk if not for the miles tall vulpine cuddling with him.

A whole hour of growth with his boyfriend… what a crazy date. As far as he could tell, they were still getting bigger too. Not as quickly or with the ferocity of that growth spurt once the gifts were damaged though. It was a dull, warm throbbing that permeated every muscle group on his body. He’d lost the ability to see beyond his chest several minutes ago, but he could definitely feel the growing. Every part of him fought for space, creaking and pushing more and more like they were in a race to outgrow the other muscles. No ferret was ever meant to be this enormous but he made it look good and then some. And each ton of bulk to his physique was matched two-fold by the swelling of his package.

The ferret wished more than anything to just be able to bring his hands forward to take care of his engorged equipment. It felt like the worst, or best, edging session of his entire life. A constant trickle of precum was dribbling out, enough to flood cities before he would even climax once. In fact each testicle could’ve sat comfortably on top of a major metropolis with room to spare for smothering some nearby suburbs. And the pillar of ferret meat that jutted out on top stretched miles out into the distance, cum churning and waiting for a chance to blow yet again.

“What do you think Mat?” Zev boomed from above. The vulpine was truly a giant now, sitting on the ground with his torso in Quebec and his paws stretching far out to the Ontario border. Helicopters flocked to his paws as news teams from around the world came looking to get a glimpse of these two titans of masculinity. And although the fox still missed having his muscles to show off for the cameras it was nice to have appreciative fans of his fox soles. The ground cracked ominously underneath his rump, bedrock below it splitting and fissures spreading all across the province.

“W-What do you mean? Think about all of this? W-Well… ohhhhh please keep doing that,” the ferret squeaked blissfully as Zev stroked his pawpad along that hyper member. Zev snickered and redoubled his efforts to make the ferret feel good. It was nice to have someone to receptive to even the smallest stroking.

“Well, what I mean is… are we big enough yet? Had your fill from our growth date yet?”

“D-Don’t stop please… eep, I mean… n-no I don’t think so. I want to see you color the sky orange.”

“Yeah, I agree. Maybe once I grow into the southern hemisphere. We can decide then.”

“O-Or further. That’s a whole hemisphere to fill after all. Why s-stop?”

“Maybe you’re right. This date seems like it’s just gonna grow longer from here.”
