(There are 2 versions of this story! One starring a puppy boy, or a kitty girl. It's the same story with the wording swapped around – but this is the puppy boy version! If you'd like to read a macro story starring a kitty girl instead, check the submission next to this! Thank you.)

A cute little puppy was enjoying himself at home. He used his toys and blocks to make a little city in his bedroom, and didn't anticipate anything other than having a fun afternoon playing with it by himself!

Marco's little tail wagged as he crawled around on the carpet on all fours. He liked playing around with his cat doll, but something was a little off...

"Hmm... this doll's a little too big for this city. They can't even get in the doors!" The puppy complained, dropping his doll. He was trying to think of how that would work. Though, as he tried thinking of how to work around his problem, he felt an odd little tingle...

"Huh?" He looked down at himself. He felt... bigger? Maybe he was just over-thinking it, but as he went back to thinking of what to do with his toys, he felt his little red t-shirt tighten around his body a bit.

"Uh oh..." the pup quickly stood up. He WAS getting bigger! He was as tall as his mom and dad. But his clothes felt really weird to wear, and move in! This was getting strange... he didn't get what was going on, so the little pup started to run around his house, looking for his parents and figure out what to do! He realized, if he got any bigger he might not be able to fit in his house anymore, or get out of it! So he ran outside to his front yard for safety.

He looked around the neighborhood, and it sure wasn't empty! There were plenty of families around, including a kitty across the street he was friends with. Would anyone be able to help him? Or was this just going to be more people who would laugh at him and this weird situation? He was starting to worry as he could hear his stretched clothes reaching their limit and begin tearing apart. “Ahhh!”

His little yelp made the whole neighborhood look over to see what was going on. Everyone was curious! There was a big puppy growing right on their own street! Was this real? Was it some sort of inflatable doll? It took them a moment to realize it looked just like their puppy neighbor, and how real he looked too!

“Wow, what's going on?” The little kitty walked up to his front yard, staring at her friend as he somehow grew larger and larger in front of her. “Is that you, Marco?”

“Y-yeah!” The worried pup barked, feeling nervous as everyone surrounded him, as his poor blue shorts had so many tears and openings, all the fabric was becoming undone! Thankfully, the pup had on a little pair of white briefs underneath – and surprisingly those weren't coming off first, since undies were more made to stretch and fit with a person's body. But the threads were still getting stretched way more than they should! The waistband had already broken too. The little pup had barely realized his neighbors were going to be able to see through his shorts and undies soon. He was more worried about growing big! He was already reaching the second story of his home as his parents walked outside to see what was going on – surprised to see their son the same size as their home!

“I don't know what's going on!” The puppy waved his arms, which made his shirt rip, and finally fall off! The red threads of his outfit fell down to the crowd below, as the shirtless pup blushed, and looked down at his shorts!

The neighbors were starting to pull out their cameras and film whatever was going on. Though everyone meant to just film the strange giant animal growing in their neighborhood, it also meant they were about to witness a macro pup close to losing his shorts in public! If he kept growing and his clothes kept tearing, they'd have a nakie puppy out in the open where everyone could see him! Not only that, but lots of people around the city might see his naked puppy butt, and his floppy lil wiener and balls! 

RIIIIP!

His shorts fell down to the ground along with his shirt. It was hard to hear what his parents or anyone was saying below, everyone was talking! And as his clothes started to come off, the other cubs in the neighborhood giggled and laughed along as they watched!

“His shorts!” The dog's mama covered her eyes. “Our son's shorts came off!”

“Cover your underwear, son!” His dad barked from below, but with so many people saying things, it was hard for his parents to try to protect their son's dignity!

“Oooh...” the kitty clasped her hands together, her eyes all big as she looked at her male neighbor all large in front of her in just his underpants! She could see his tan fur sticking out in the space between the white threads of his underwear. She could even see some bumps and grooves where his private shapes were tightly tucked away behind them! Some of the parents in the neighborhood noticed his private parts starting to become visible through his underwear, and covered their little ones' eyes! Some of the girls and boys were curious to watch, but their parents didn't want them to see a giant puppy's peepee spring out of his underpants!

“Oh no... oh no...” he looked down, seeing his undies tear more from the top and the leg holes, with the white fabric looking more and more transparent! “Mom! Dad! My underwear! It's...!” As he heard a loud rip, he quickly threw his paws between his legs! “Noo!”

Everyone gasped as the little (big) doggy's underwear fell down around his biggole feet. He was at least three stories tall now! He covered his privates and whimpered, before feeling a breeze against his butt, turning around to see his big nakie tushie was totally showing!

“Oh no! My butt!” He looked back and forth between his privates and his bottom. He shifted one paw over to hold as much of his weenie and balls as it could, and let the other paw slip down between his butt cheeks to try and cover them up too! Though, depending on when he walked, sometimes the people behind and underneath him could see a glimpse of one other embarrassing little hole back there...

“What's going on?” The mama dog asked her husband. “Why is he so big? Is this real? I feel like I'm dreaming...”

The dad shook his head, “More of a nightmare! Worse than those dreams where I'm naked at school – but it's our son! And he'll be naked in front of the entire town!”

The kitty girl ran behind the giant Marco, giggling at his plump little butt all bare to folks below! “Wow! So that's what a boy's butt looks like... it's so big!”

The little pup was so embarrassed! He was trying to cover up his little cubby penis and balls, as well as his buttcrack, but he really wanted to figure out how to stop everything and go back to normal! It felt hard to do if all he was focused on was covering his privates. But as he kept growing, he could see more and more homes and roofs, and more of the city around him! That means everyone in every home and building could probably see him too! Who knows how many people were recording video of the giant puppy! Would they know he's a person or think he's a monster? He was just a little pup! 

Anyone watching their TV got an alert about what was going on in the news!

“Breaking news! There's a giant naked dog growing in our city's neighborhoods! He's not stampeding through city buildings or anything dangerous yet, but be alert – we're coming to you live with footage!” The news-hamster cut to helicopter footage, where the news was filming the pup from high in the sky! “Oh! Also, this giant dog doesn't seem to be wearing any clothes. He seems to be keeping himself decent, what a good boy! But just in case his paws slip, there might be some graphic displays of nudity and who knows what else, so... be careful who in your household is watching!” This was his hint to tell parents to cover their kids' eyes!

“Arooooo~!” The pup howled, feeling confused and worried about what to do. He didn't want to destroy anything, but his feet were getting pretty big! He did see a nearby park, and figured that would be a safer spot for him to stand. “I'm going to walk to the park!” He yelled down at his parents, before tip-toeing naked down the street. He fit one paw at a time down the road, without really thinking much of the people below who could see between his legs as he stepped! As much as he hid his butt and penis fairly well, the bottom bits of his balls weren't completely secure, and quite a few folks were surprised to see his little puppy hole too!

“Gosh!” The kitty blushed as she ran along to the park, surprised to be seeing such an intimate part of a neighborhood boy.

He had to take one big step over some fences and houses to get to the next street, and then again when he had to step into the park. He was such a good behaved doggy, and made sure everyone knew to run away as his biggole footy paw loomed over the park's grass before stepping his paws down.

“Ugh... what am I going to do?? If I grown any bigger, I'm not gonna fit anywhere! I'm gonna get so big I'm gonna destroy everything! And then people will get mad at me, and, and...” he started to tear up a little as he got scared! Now he was embarrassed being naked and trying not to cry. His paws instinctively went up to his face to cover up and hide it. But that meant he wasn't covering up his nakie parts anymore...

“Oh gosh!” “He's naked!” “He's exposing his parts!” “I can see his butt!” “I can see his penis, haha!”

His parents of course were surprised and disappointed he didn't keep himself covered, but seeing him hide his face in his paws, they knew he must be feeling pretty bad, and hurried over to help him!

“Uh oh!” The news-hamster gasped as the flying news helicopters were focused on the cub's tummy at that moment. As he lifted his paws, nothing was hiding the view of the macro dog's cubby parts! His soft and scared puppy penis was dangling out in the open! And his fluffy puppy balls were bunched up below! It was like flashing a zoom-in of someone's genitals live on TV! ...Well, actually it was just that. But it was an accident since this was a naked giant! “Oops, well, please be advised – we're just recording this event as is proceeds. This is intended for a mature audiences only!”

All kinds of people at home were shocked to see a puppy's balls and weenie broadcasted live over TV! Even animals in restaurants and professional places were shocked to see a close up of a very cubby-looking set of genitals on TV! But this was an emergency, there was a giant in the city! They had to keep an eye on it. But, when it's naked, it was hard to show where a giant was and what was going on while also live-censoring its crotch. They didn't even bother making an attempt though!

The news helicopter did try and fly around behind him instead. They had someone yelling at them in their headsets not to get close-ups of the giant's privates! But by turning around, it meant his chubby little puppy butt was on TV instead! For some people, that was better than having to see his penis. For others, it was less exciting! Or for some, it gave them naughty thoughts either way. 

Lots of people liked butts, and not everyone knew this little dog was a cub! Though, maybe some could tell it was a cub – and with that, maybe some of the city folks enjoyed seeing one naked, while others did not! Some younger cubs probably felt very differently seeing one of their own naked on TV! Meanwhile, most adults probably weren't too excited knowing there was a naked cub on TV, but some naughty ones were probably very excited and happy for this rare treat, and maybe even tried to record what they could of it! It sure wasn't often a nude puppy boy was allowed to have his genitals showing on TV in detail. And maybe some people had no idea it was a cub and still thought this was cute or exciting or naughty, and would be surprised by the information later! Either way, this was a city-wide phenomenon. It was hard to keep it a secret if someone was giant and naked. It was basically unavoidable! Even people driving down the road were surprised to see what looked like a giant naked puppy standing around in the distance.

The puppy shook his head, and his brown ears flopped around back and forth. Marco looked down at his giant macro body, and saw below his tummy, his soft little penis and balls were showing! It'd been a little while, and he'd probably already flashed the entire town! Was it even worth covering up his little winky anymore? Surely everyone who wanted a photo already got one. But maybe it was best to hide himself anyway! He also just realized he was touching his butt and penis a moment ago and touched his face right after... but it wasn't like he could wash his paws right now. The beach was very far away!

“Oh my gosh, how many people saw my thingy!?” The puppy tried tucking his little softy between his legs – scooching his butt out a bit so his little thingies could hide between his thighs. Of course – this just meant some of the people behind him could see some puppy balls down behind his butt! They weren't really well-hidden.

At home, the kitty's father was watching with wide eyes. “Woah! That's the neighbor dog, naked on TV!” He blinked and blushed, surprised to see a puppy so exposed on TV! And a boy too. He couldn't help but pause the video and catch a glimpse of his lil puppy penis and butt, looking in close and enjoying how excited and aroused it made him! “Uh oh...” he gulped. “This is a little weird... but it is kind of exciting, and a rare circumstance...” he started to hold between his legs as he un-paused the footage and started to watch again. “I know it's my daughter's friend, and he's normally right across the street, but he's just so cute...!”

The apple didn't fall far from the tree – the kitty girl was excited to see the pooch next door at the park. She giggled as she saw him with his bits tucked between his legs. She could still see the furry base of his penis tucked between his legs, despite his efforts to hide it!

“How am I going to get out of this situation? What do I even do??” Marco thought. “How did this even happen? I was playing dolls when suddenly... I just started growing...” He tapped his chin curiously.

Meanwhile, on the news, they had a full-length camera catching the giant in its entirety! And still, they were showing off a naked puppy to everyone in town! Even his butt and weenie. Though, at least his front was tucked down a bit. “I sure hope our audience at home is behaving themselves! It looks like the dog is thinking of something...”

The cat dad watching from the privacy of his own home shook his head, “I'm not behaving... but he's just so attractive like this! I... I...!” He meowed and closed his legs, as the perverted old father got off to seeing his puppy neighbor naked on TV! But he probably wasn't the only one cumming to a cub right now...

Marco tapped his foot, which slowly made his penis start to slip out from between his thighs. “Hmm, I was just imagining how my doll could fit in my toy city... it was too big to fit! And then I became too big...” He could connect those two things together, but logically, why would that make him start to grow bigger? He was just using his imagination!

“It wasn't real though, I was just imagining it... am I... just imagining this??” That sure would be lame if that was the case. Though it would be a relief to him if it meant he didn't expose his nude little body to thousands of animals in the town around him! And who knows how many people on the internet had seen by now too... No one was going to write stories about this and post it online, would they?

“Yes! This is SUCH a big story!” The news-hamster giggled, spinning in his chair. “That poor dog, the year barely started, but he's already broken our news record ratings! We'll have to make sure to get him some dog treats. Uh. Maybe it'd be good if he shrunk down to a smaller size so that wouldn't be so expensive...”

The kitty girl watching with wide-eyes saw how excited the puppy was to try and connect the dots between the events. Though, his excitement affected his little winky too... even though he was just a little cub, it started to poke out a little more... it began to twitch, and what normally was just a little inch grew into two... (well, maybe here it's two feet? Two yard? Miles? Kilo-whatevers??)

Regardless, his parents were shocked to see their puppy was getting a little boner in public! EVERYONE in town was able to see their little cub erect! This was VERY inappropriate! His dad tried jumping around, waving his arms, “Son! Cover yourself up! Cover yourself up!” 

The super-tall macro Marco couldn't hear his papa below, he was too caught up finding the answer to his adventure! “I... I... I must have imagined... what it was like... being too big? Maybe I imagined so much that I grew?” He waited around, as if announcing the reason for what was going on would be enough to reverse it. “No? Is that not it? I'm so close! I'm definitely close to it! Mmfff... what is it??”

As the news cameras circled the pup, the camera yet again caught a glimpse of his puppyhood, sticking up, cute and innocent, right on camera! The news-hamster squeaked, “Hey! Come on! Fly up to his face or something, leave his weewee alone, we've got enough footage of that.”

While some yelled at their TVs for the hamster to mind his business and enjoyed the views they were getting, others didn't think they were putting enough effort into NOT showing his puppy parts at all! How hard was it to film a face??

“I'm almost there...” the puppy huffed, “I've almost got it...” he whined. “I... I....”

Everyone gasped and watched, “What's going on...?”

“I... I...” Marco squeaked, the big naked giant, who was just a little cub, clenched and squirmed their legs around as they felt something big and new happen! “I... AROOOOOO~!!”

Everyone's jaws dropped as they saw his little puppy penis spasm around. It twitched up and down, throbbing and wiggling as his body froze up and shook! His little winky was doing a lot right in front of the camera... but he wasn't sure what! However – most of the adults probably knew what was happening...

“Awoooooo....” the puppy huffed and whined, suddenly feeling dizzy and weak. The moment hit its climax, but... nothing came out. His balls were moving around, tightening, churning? But his puppy weenie simply flopped and flipped around until it started to not hang up so much, and slowly started to soften and go down again.

“Dry???” The news-ham gasped! “Oh my gosh, I uh, think we just watched... something...” he blushed a lot, staring at the camera with a goofy face. He didn't want to have to explain what they all witnessed! “For some reason, I guess nothing came out... of that...”

It's easy to imagine how many different reactions everyone in a massive city would have to seeing that! A bit too many to go over in detail... the puppy himself however felt his eyes close, he was calming down... feeling less worried. All the pressure and worry that built up seemed to finally fade away, and he was publicly bathing in the aftermath of pleasure...

“Whew...” Marco sighed. He felt himself... starting to shrink!

“Hey! It's happening!” His mom pointed – delighted to see her son not growing any bigger, even though she just had to witness him having a dry orgasm in front of the whole city.

“He's shrinking down again! Thank goodness...” the puppy's papa was so relieved. Maybe he'd go back to normal again! Well, normal as you can after being a naked giant.

“Oooh...” the kitty watching him was rubbing her little paws between her legs. She really liked everything she just saw! She probably didn't climax like Marco did, but she'd likely be thinking of this even lots and lots in the future! Just like her own father would... actually, just like the whole town would! Like the whole internet would too! Oh, that poor, poor puppy...

“I'm getting small again! I'm getting small again!” The nakie tan puppy hopped around excitedly in the park – which made everyone fly up into the air just a bit, and land on their feet and bottoms. “Woops, sorry!” He noticed the crowd below him were bouncing up and falling down because of him.

He didn't even cover up his puppy parts! He was back to being four stories tall... three stories tall... the news all caught his shrinkage live on camera! And horny adults or cubs or teens watching were catching their last glimpse of the live show! They were all still in disbelief. For some reason, everyone in town got to see a totally cute naked puppy boy on display, either in person, on the news, or however they saw it! It was quite the naughty little show! And one that would stay in the town's history forever.

The pup shrank down to twice his parent's height, smiling down at them. “Hi mom! Hi dad! Look, I'm shrinking!”

“We're so glad you're safe!” The mom cheered, happy her little guy was alright.

“T-try covering your parts, junior!” The dad pointed, as the doggy looked down and blushed. 

“What's the point? Everyone already saw them...” he sheepishly threw a paw over his little penis, which was all soft and squishy and cubby again.

Some random members in the crowd were all yelling different things, it was hard to keep track of. “That was awesome, you were giant!” “We all saw your little cubby dick!” “How did you do that?” “Nice butt, dude!”

The lil pup hugged his parents as he kept shrinking back down to size. Soon, he was all back to normal, and his parents held him up to their chests. Everyone could see his tail wagging above his naked little cub butt. The little kitty and a few others could see the cub's tiny ballsac bouncing below too! She sure loved everything she saw today!

“That was quite the event, but it looks like the little guy's all back to normal!” The news-hamster announced, as live footage was shown at the park of the family reuniting. “Ahem, it also looks like the giant was just a little cub named Marco. I don't think we'll be replaying any of this footage uncensored during our evening broadcast, but everyone sharing photos of the naked cub online, please be advised to be careful! You're... probably not allowed to do that anymore. Woopsie. Signing off~!”

After all the interviews and talks in the park, Marco was ready to head back home. Everyone had already seen him nude today, so he actually got a bit relaxed and stood around naked and uncovered! His mom kept trying to put a blanket around his nude body, but he just wouldn't have it. The tiny pup stood proud and naked, with his shrunken little genitals just hanging out in front of the crowd – hands on his hips, and a smile on his face, “I'm so happy to be back to normal again!”

He took his parents paws and started walking back home. It was a little naughty... his parents both blushed, each holding his hand, so he couldn't cover up his private parts, and he sure didn't want to! Everyone behind saw his cute little buttcheeks bouncing with every step as he headed down the sidewalk with them. Everyone in front saw a surprising little set of cubby balls with a floppy little wiener wiggling around on top! It was pretty inappropriate and naughty... but as the city's new, famous, nude giant... if anyone was going to be naked in town, it'd be the one cub they'd all seen already anyway!

The kitty blushed, seeing her naked neighbor walk by! “Hehe, hey Marco!” she wanted to be naughty, but decided to be polite first. “I'm glad you're okay!”

The naked doggy boy smiled, “Thanks! Sorry you had to see all that.”

The little kitty blushed, her legs squirming together tightly, aroused at the sight of the cub boy in front of her. “It's okay, I think you looked cute!”

The lil dog laughed, “What!? Huh... well, thanks. Just wait until it happens to you!”

“What??” She tilted her head, confused as she stared at the naked lil puppy butt walking off into the distance, back home with his parents, where good little pups belonged!
