"Well, there's only one way to find out!"

Those words had been echoing in Kodi and Dusty's mind for the past five months now, ever since their first anniversary, and their introduction to the amazing sensations of air inflation. Kodi would have never thought it possible to use air to inflate his already ginormous balls to an even bigger size, and Dusty couldn't believe it when her belly had grown to four metres in diameter once Kodi had climaxed in her with his ballooned balls. And it was all thanks to Balto and Jenna.

The two older canines were waiting in the Boiler Room for Kodi and Dusty to join them, Balto lying on his side, inadvertently displaying his humongous balls and sheath, while Jenna lay next to him, nuzzling her head against his. They both looked up when they heard pawsteps. Kodi and Dusty were walking in, smiling slightly.

"There you are - we were wondering where you were," Jenna asked.

"Eh, things happened - unexpected or not, we can't just tell the pups to get lost," Kodi said.

Dusty's past pregnancy with her and Kodi's first litter was certainly not one they expected. As it turned out, Dusty had gone into heat the day she and Kodi celebrated their anniversary, unbeknownst to the two, and, as such, Kodi had fertilised every egg Dusty produced that season. The two loved their pups, however, and were overjoyed when they realised that Dusty was pregnant. She had given birth to six beautiful puppies twelve weeks ago. And, much to Kodi's amusement, the boy had inherited his and Balto's hyper endowments, but, like Kodi's brothers, wasn't the same exact size as Kodi and Balto.

Back in the present, Kodi and Dusty padded up to Balto and Jenna, just as the older couple sat up.

"Understandable - they are a bit of a handful," Balto said, nodding.

"More than a bit," Kodi joked. Dusty nudged his side.

"They get it from you, you big lug," she said. Everyone laughed.

Calming down, Kodi added, "Oh, but as much as I love them...I think I'm gonna need a new way of relief if you do get pregnant again soon, Dust."

"You were a bit...full, back then," Jenna said.

When Dusty was discovered to be pregnant, it came with quite a bit of a predicament for her and Kodi. While Balto and Jenna were able to continue having sex and inflating themselves, Dusty's pregnancy meant she was unable to do either. With how big Kodi's endowments were, there was a very real possibility of him harming the pups during their gestation, and neither of them wanted to risk air inflation doing anything to them either.

But that also meant that Kodi was unable to sate his sexual desires as well. He was a faithful dog, and his heart belonged to Dusty only, and he only wanted to fuck her. And with Dusty off-limits due to her pregnancy, Kodi was stuck. Sure, there were plenty of females in Nome who would love to have him fill them (in particular, Sylvie and Dixie being openly willing to offer their hungry pussies for him to ravage), but Kodi was not so desperate for relief that he would cheat on Dusty. And there lay his problem.

Without Dusty able to help him, Kodi had a 'dry spell', so to speak. He tried to manage it, but he only achieved eight weeks of abstinence before his 'cum-block', as he put it, was too much. Two months of no release resulted in Kodi's orbs becoming painfully full of cum, and bloated to twice their usual size, even with him constantly leaking pre-cum in a feeble attempt to alleviate the pressure. It got so bad, that one day, in the middle of a street, Kodi had to release, and so ended up rubbing his humongous dick until finally, weeks of repressed spunk exploded out of him, resulting in the entire street being flooded in hot, bubbling seed as Kodi sat and rode out the waves of euphoria he experienced.

"I don't think I've ever cum so much as I did that day," Kodi reminisced, before he winced when he remembered the immense pain his testicles went through.

"I know the feeling, son. Happens to the best of us. When your mother was pregnant with you, I decided to try and go without. I still remember the pain I felt back then, trying to lug around balls three times too big," Balto said, chuckling.

"Three times? I was only twice as big as normal!" Kodi exclaimed.

"You know how productive your father is, Kodi. Besides, I think he lasted longer than you - what was it, ten weeks?" Jenna asked, looking at Balto.

"Eleven. You were still resting from the whole ordeal, so I couldn't just fuck you after the pups were born. But I had to release by then, so I just masturbated in the town one day," Balto said.

"I bet that orgasm was a big one," Kodi said.

"I pretty much flooded half of Nome in one go," Balto stated. He glanced at his massive balls, adding, "Although, I do wonder what would have happened had I fucked a bitch to release that load."

"I don't want to try it. Cum bloated balls feel too painful - much too different to when we inflate them," Kodi said.

"To be fair, your spunk is heavier than air, so that might be a reason," Dusty chimed in. Kodi and Balto laughed, while Dusty and Jenna shared a knowing grin.

"Anyway, back to why we're here," Jenna said. She stood up. "I think it's time we started our contest, don't you?"

"We're doing it here?" Dusty asked.

"No, of course not. We've found a better place. Come on," Balto said. He stood up as well, and, together with Jenna, led Kodi and Dusty out of the Boiler Room, and across the town to a large, old factory on the other side of the settlement. The factory had been recently closed down, due to a larger, more efficient one having been built in the next town over, and the humans hadn't gotten around to repurposing the building, or demolishing it. But it was the perfect place for the four dogs' competition, as Balto and Jenna discovered, thanks to one of Jenna's friends, that the factory had several large tanks full of compressed air.

Compressed air that was soon going to find a brand-new purpose.

Reaching the factory and heading into a large room inside, Balto and Jenna started to explain to their son and daughter-in-law why they chose that place.

"You see, a few days after your anniversary, we realised that the foot pump wouldn't be enough for our competition. It's too slow, and there's only one," Balto said.

"So, we've been looking about for a while to see if we could find more ways to inflate ourselves. We asked around town, and Mallory recommended here. You guys remember Mallory, right?" Jenna asked.

"You mean the chinook that has a disturbing fetish for balloons?" Kodi asked.

"Bit rich, coming from a dog who likes to inflate his balls and use that to inflate his wife," Dusty reprimanded.

"Yeah, well, according to her, this place has a lot of air tanks. She used one to blow up a load of balloons, and it took her only a couple minutes with a tank what would have taken at least two hours with a pump," Jenna said.

"Really?" Kodi and Dusty asked, surprised.

"Yeah. We tried it a few weeks ago, just to make sure it works. It was amazing," Balto said. He grinned as he trotted over to four large air tanks, all full and ready to start flowing. "We made sure to keep these four full for today, but there are plenty more all over the factory," he explained.

"Wow. This is gonna be fun," Kodi said excitedly, his cock starting to erect, peeking out his fat sheath.

"Very fun," Jenna agreed. She smirked at Balto. "So how we going to do it?"

"We could go altogether - start at the same time, and see who lasts the longest, and grows the biggest," Balto suggested. Jenna smiled, before she looked at the others.

"What do you think?" she asked.

"I agree with Dad - it's the best way," Kodi said.

"So long as I get to be inflated again, I don't mind," Dusty added.

"Then we'll do it that way. Since you two," Jenna said, looking at her husband and son, "will stay ground level, you're in charge of the tanks. We'll all start our own, but since Dusty and I are inflating our bellies, we might not be able to turn ours off if we need to. So if Dusty or I ask either of you to stop our tanks, stop them."

"Of course, Jen," Balto said.

"Makes sense, Mom," Kodi agreed. Jenna smiled.

"Then let's get set up."

For the next few minutes, the four went about setting themselves up for their competition. Balto and Kodi searched around, and found new nozzles for the hoses attached to the air tanks, small enough to be inserted in their dicks without discomfort, as well as two nozzles that could be easily placed in Jenna and Dusty's vaginas, while Jenna and Dusty managed to clear the floor enough so that they all could comfortably stay where they were.

Finally, once they had found everything they needed, they did their final preparations. Balto and Kodi inserted the larger nozzles in Jenna and Dusty, before the girls returned the favour, inserting the smaller nozzles in their mates now fully erect dicks. Kodi smiled at Dusty once she had stood up, before pulling her close to kiss her on the lips.

"Don't go getting too frisky, Kodi - we can't inflate each other if we're tied," Dusty said, smiling.

"I'd be up for the challenge," Kodi replied, smirking. Dusty giggled.

"Everybody ready?" Jenna asked, once Dusty stood away from Kodi.

"Uh-huh," Kodi said, nodding.

"Ready," Dusty answered.

"I've been ready since this morning," Balto commented.

"Okay, then. Let's get to it," Jenna said. She placed a paw on the valve on her tank, and the others did the same. "One three."

"One." Kodi could hardly contain his excitement.

"Two." Dusty's pussy was already spasming in anticipation.

"Three!" Balto spun the valve at the same time as the others, and immediately started moaning.

Four loud hisses sounded out, as the quartet of air tanks started flowing, air rushing through the hoses into the four canines. Instantly, Kodi and Balto's balls started to inflate, while Jenna and Dusty's wombs expanded, faster and rounder than before. Kodi shivered as the cold, compressed air ran through his hot, throbbing shaft, flowing right into his balls as they grew and grew.

"Damn, this is better than I thought!" Balto moaned, placing a paw on his balls as he felt them blow up, air filling the orbs at the fastest rate the wolf-dog had ever felt. Already, they were so big that he had to spread his legs as far apart he could.

"Nngg, Kodi, maybe you should try it like this as well," Dusty groaned. The cold air felt so good on her convulsing walls, cooling off her heated uterus as she was stretched and inflated. If she thought having Kodi inflate her with his cum alone was sensational, and having him inflate her with his cum and air was delightful, then this was just mind-shatteringly delectable! Her womb and vagina were swelling at the same rate, and she was already lying on her belly, the sphere of fur so big that her paws were a few inches above the ground.

"I-I think I'm all right with this for now, hun," Kodi said. He had stepped forward so that his balls had more space to grow. It had only been a minute, and now they were two metres big, a task that had taken him and Dusty just over three minutes last time.

Jenna had remained silent, just basking in her orgasmic state of mind as the flow of air tickled and rushed over her sensitive walls, stimulating the parts of her genitalia that only Balto was allowed total access to. Words were irrelevant to her at that point - all her mind wanted to focus on was the intense sensations travelling along her body. She had stretched her legs out as her belly grew far too big to be contained by her body, easily letting her rest on top as she reached four metres in size. Dusty was at the same size, and growing at the same rate, but both girls were too focused on their own pleasures to care who was in the lead.

The girls now both towered over Balto and Kodi, but the males weren't concerned. After all, it wasn't their bellies they were ballooning out. Their giant testicles were growing at a slightly slower rate than their mates' bellies, but still faster than they had become used to. Balto smirked over at Kodi for a second, before closing his eyes and just enjoying the feelings. Having outgrown his previous inflated size, he thought it would have hurt, but the swelling orbs just continued to send only pleasure to his brain.

This is so much better than the pump! Balto thought. He moved a paw to stroke his balls again, shivering at the feeling of his rough paw pads on the soft skin of his tender orbs. They now stood at three-and-a-half-metres in diameter each, but Balto wanted them bigger. He would not be satisfied until they were as big as possible!

Moans and whines sounded out around the factory, the four canines all lounging in their own little worlds of pleasure. Dusty and Jenna were seeing stars, their minds, so used to their previous methods of inflation, unable to properly cope at this time. There was so much information to process in such a short amount of time that, rather than try, they just shut down to the most basic of systems - pleasure, and life.

Time in that factory passed at a much faster rate for the group, all of them unconcerned with the length it took to reach their sizes. By this point, Jenna and Dusty stood ten metres tall, while Kodi and Balto's balls sat a snug five metres. But there was still plenty of air left in those tanks.

Dusty subconsciously placed a paw on her belly, pressing on the inflated skin and feeling it bounce out again. At this point, all she could see was her expanding stomach, and Jenna not too far away. Kodi and Balto were gone at this point - all Dusty wanted was to inflate. And inflate she would. Her entire body was a tiny boat on an ocean of belly, the sea of grey fur soft to the touch, and making her shiver in delight at every little movement she made.

It took another ten minutes, but finally, the four started to reach what they perceived as their limits. Kodi was the first, stammering out, "I-I can't take any m-more." He managed to turn his tank off, and pull the hose out of his dick. His balls were now a whopping _fifteen_metres in diameter, and Kodi feared any movement would set him off, having been put on the edge of orgasm for ages.

Dusty was right behind him. Feeling her belly shudder in protest, she yelped, "Kodi, stop it! I'm big enough!"

With difficulty, Kodi managed to quickly shut off Dusty's valve, leaving his wife lying on top of a thirty-metre-tall belly. He just gawked at her size, wondering just how his slim mate was able to stretch and bloat that big.

Jenna and Balto kept at it, swelling out their respective genitals until they too felt it was enough. Balto shut his valve when his balls sat fifteen-and-a-half metres big, while Jenna demanded hers be stopped when she reached thirty-one-metres in size.

Panting and huffing, Jenna grinned down at Dusty as she said, "Looks like I win." Dusty scrunched her face up for a second, before laughing, saying, "Yeah, you did."

"And I guess I won, too," Balto said, smirking at his son.

"Don't rub it in, Dad," Kodi replied. Balto couldn't help but laugh.

"Okay, boys, now it's time to really finish this," Jenna said.

"Yeah, come on, guys. We're _needy_up here," Dusty added. Balto and Kodi smirked at each other, before they, with awkward and difficult movements, managed to climb up a series of stack boxes and crates next to Dusty and Jenna, somehow managed to move with their ginormous balls and not knock anything over, before leaping up and landing on their respective mates.

Kodi smiled as he stumbled along Dusty's swollen stomach until he stood behind her body, the air hose still attached to her clenching pussy. With quick movements, he pulled his free and tossed it aside. No need for it now.

Balto had already freed Jenna's hose, and was now lining his throbbing tip with her eager spade. Despite Jenna's ginormous belly, he still managed to hook his paws around her hips, ready to spear her apart, as he had done many, many times before.

"How much do you want it?" he asked his wife.

"Don't tease me, you bastard. I've been stretched on the edge of cumming for ages - I need that cock of yours in me!" Jenna shouted. She was right - her teased pussy had been taunting her mind for release ever since she turned on the air. If anything could send her over the edge, it would be Balto's massive cock.

"Needy, needy. Tut-tut. We can't have that now, can we, bitch?" Balto asked. He glanced over at Kodi, and grinned when he saw his son was readying his hips to thrust. Shuffling a bit to ready himself, Balto grinned down at Jenna, saying, "Get ready, cause I'm not holding back."

With that, the two hyper males thrust into their eager bitches. Immediately, Jenna and Dusty yelped in shock, their mounds stretching apart as their mates' humongous cocks spread them open. Slick with their mates' fluids and their own abundant pre-cum, Balto and Kodi slid in the two females with ease, until their massive knots bumped against their openings.

"Oh, God!" Dusty screamed, feeling Kodi stretching her apart as he pulled back, and slammed forwards, letting a loud slap_sound out. His massive, ballooned balls flapped and swung behind him, slamming themselves against Dusty's bloated belly with a satisfying _thwack each time.

"Fuck me, Dust, you feel so good! So damn tight!" Kodi grunted, panted gasps being breathed into Dusty's ears, tickling the fur on her head. She moaned in reply, her words thrown to the air as Kodi fucked her.

On the other side, Balto and Jenna were thrusting against each other. Balto was breathing deeply, pumping with force and abandon as he grew determined to knot his bitch. His swollen balls wished to empty their load in her inflated belly, and give her a real reason to moan. Jenna hissed and panted, hearing the satisfying splaps as Balto's knot failed to burry itself in her again and again. She knew he would do it, though - they had enough practise before. But having reached near her breaking point, Jenna's mind refused to allow her the decency to control her voice.

Balto knew his wife was not able to talk, and smirked as he said, "Speechless, huh? Don't worry; I'll have you screaming my name before you cum. That I promise." Jenna just _whimpered_in response, her brain fogging over. The pleasure of being fucked after having inflated both her belly and Balto's balls was too much for her to handle!

The noises grew louder and faster, echoing around the room as the dominant males started to really fuck their partners. Dogs and humans in the town could hear Dusty and Jenna's screams and pants, and Balto and Kodi's howls and yips, but no one dared go and interrupt them. They were all used to seeing the four have sex wherever they wished in the streets, so hearing them, but not seeing them, was not too different.

The wolf-dogs started to grow desperate. They were now so close to cumming, but they hadn't worked their knots in. Balto could even feel his humongous balls start to tighten. He gritted his teeth, holding back a moan. He refused to let loose without a tie - if he was going to seed Jenna, it would be with a full knot.

Determined to get his knot in, Balto pulled back, and crashed his hips forwards. The loud smack that sounded was music to his ears, but the absence of the necessary pop disappointed him. He pulled back again, making Jenna moan as her sensitive walls stretched out, before slamming in again.

Kodi was faring no better. His knot was refusing to go in, and Dusty, although willing, was in no state to help. Her legs were permanently spread across her swollen belly, stretching her opening wider, but her wolf-dog husband was too big. All their past matings, even their past inflations, had vanished from their minds. They were the young couple they were one year ago, Kodi claiming Dusty's virgin body for his own.

"I'm gonna rip that little cunt of yours wide open, bitch. Our next litter will be able to march out of you by the time I'm done!" Kodi snarled in her ear.

Moaning at his voice, Dusty weakly replied, "Oooh, do it, Kodi. I'm your little bitch! I'm a hole for you to abuse! Fuck me like the wolf you truly are!"

Kodi smirked, pulling back at the same time Dusty managed to stretch herself forward on her belly. Nearby, Jenna and Balto had done the same. Then, like a true father and son, with movements in full synchronisation, Balto and Kodi thrust in.

POP!

The two loud, wet noises sounded out with such gratification that Kodi and Balto nearly came there and then. They managed to contain themselves, however, but Jenna and Dusty screamed and _squealed_in delight, their well-hung mates now locked deep inside their inflated bodies. Unless by some absolute divine prank, there was no escape for the two bitches; they would be bred full and proper, as they always should be.

Mother- and daughter-in-law happily rocked on their bellies as their husbands fucked them, the huge knots pressing up against their clitorises with such pressure that Jenna was amazed her mind hadn't liquified from the amazing pleasure assaulting it, as yet another climax ran over her. But the extra pleasure, of course, led to extra clenching, which, in turn, led to Balto and Kodi getting much closer to orgasm.

Humping his wife messily, his massive balls still swinging about behind him like a pair of gigantic, furry balloons, Balto could feel the tightening in his balls increase. He was so close. With a grin, he shouted, "Here it comes, Jen! Better hope you're not in heat, otherwise it's pup city for you!" With that, he gave one last, hard thrust, and_howled_ loudly, holding himself deep as he erupted inside her with a wet splurt!

Hearing Balto's words, and feeling his climax, Jenna could only scream out, "Oh, BALTOOOOO!" Her mind was forced aside, letting only her instincts and pleasure control her body. She could feel each and every shot of virile cum Balto spurted into her, the thick, warm batter stimulating her walls in such a way that her body convulsed, orgasm coursing over her.

And then, a minute into Balto's cum-splattered orgasm, a wet hiss sounded out, as the air in Balto's balls escaped, his open floodgates providing it the perfect opportunity to flow once more, deflating his balls fast. Using Balto's cock as a hose, the air rushed into Jenna's belly, sending her into a near endless chain of orgasms and climaxes as her belly inflated once more, growing bigger and rounder, until Jenna and Balto lay on top of sixty-two metres of cream-coloured furry belly. And all the while, Balto and Jenna howled with each other, rocking on top of Jenna's sphere of a belly.

Kodi saw his parents as they orgasmed, and, determined to follow, whispered in Dusty's ear, "Get ready, Dusty. I'm gonna make sure you're nice and big." Dusty whimpered at his words, and Kodi slammed his hips down one last time, and howled loud and deep as his own balls pulsed and clenched, sending rivers of sperm to flood Dusty's insides.

Then, just like Balto, a minute into Kodi's cum splurting, another loud hiss echoed around the room, as his balls rapidly deflated, the trapped air inside rushing through his glistening shaft alongside his hot cum to blast into Dusty's inflated womb. The double assault of air and cum was too much for Duster, her belly growing larger as Kodi emptied everything he had in his balls into her.

"Oh, Kodi! I'm growing again! Oh, God, don't stop!" Dusty shouted, the unstoppable chain of orgasms rushing over her.

"Anything for my little bitch," Kodi said, before howling again as his orgasm continued. Dusty _howled_alongside him, her voice melding with his in the daytime sky. Fire ran through their bodies, the orgasms they experienced lasting longer than ever before, even as Dusty's belly finally capped at a massive sixty metres in diameter.

Balto and Jenna, still reeling from their climaxes, just watched in awe as Dusty and Kodi continued to cum and splurt, rocking against each other as they mixed and swirled their fluids in Dusty's womb. Jenna and Balto may have won the size contest, but Dusty and Kodi clearly outlasted them in orgasm duration.

Finally, however, five minutes later, Kodi and Dusty calmed down, their clouds of lust and pleasure fading, clearing their minds. Kodi happily nuzzled Dusty, before he looked at Balto and Jenna.

"Damn, son. And I thought I had long climaxes," Balto said, chuckling.

"Well, you can't be the best at everything, Dad," Kodi replied. He licked Dusty's head. "How do you feel, Dust?"

"I feel so full, but I love it. You really should try it, Kodi," Dusty replied. Kodi gave a nervous chuckle.

"Maybe," he said quietly.

"They really are perfect for each other, aren't they?" Jenna asked, nuzzling her head against Balto's.

"Just like you and me. A tight little bitch, for my big dick," Balto said. Jenna batted his muzzle with her head.

"Don't spoil the moment," she said.

"Heh, sorry. Got a little carried away. But you're right, they are a perfect couple," Balto agreed. He nuzzled her again, giving a few small humps into her, making her moan as they rocked on her huge belly.

Near the factory entrance, however, three little pawsteps were hurrying away.

"Whoa, did you see that?!"

"Yeah, Mom is huge!"

"We need to try that out too!"

Looks like Balto, Jenna, Kodi, and Dusty won't be the only ones in Nome who enjoy inflation.
