A commission made for Rana, featuring Kodi, desperate to find a way to make his first anniversary with Dusty a special one. As such, he turns to his parents for help, and they give him an idea that he (and they) can use to make it a very memorable day.


A few years had passed since the diphtheria epidemic that encased Nome in 1925. Ever since the Great Race of Mercy (known colloquially as the Serum Run), Balto, the half-wolf hybrid, had become the most popular animal in the town, due to his self_less_ efforts to save the original team and the precious cargo of medicine, despite Steele's self_ish_ attempts to stop him. Once the town outcast, now Balto was the Hero of Nome.

Since Steele had been driven away from the town by a hoard of angry dogs, Balto was contempt to settle with his new life. The love of his life, Jenna, the kindest husky one could ever meet, had become his loving mate, and together, they had created the future that would ensure Balto's legacy will endure. So far, they had five litters, but neither had any plans on stopping any time soon. Of course, it didn't help that the two enjoyed mating with each other anyway, Balto always happy to fuck his loyal bitch, and Jenna ever eager to have Balto claim her with the _massive_cock she had grown to love.

Massive was an understatement. Balto, and his sons, for that matter, was the most well-endowed creature on the planet- in relation to land-mass animals, that is. Being a hyper, the wolf-dog possessed a pair of absolutely humongous balls, easily able to rest on the ground between his hind legs even if he stood up straight, and a sheath that filled out half the underside of his body, while his gargantuan cock stood taller than his entire body when erect. His sons had all inherited this trait, but most came just shy of Balto's full size, except for one.

Kodi was Balto and Jenna's eldest son, and indeed the oldest of all his siblings. He was also the only one to inherit a cock and balls the same size as his father's. It made the boy proud to know that, out of all his brothers, he was the one who was most like Balto. Often, Balto and Kodi would just stroll through the town, enjoying the feeling of their mammoth orbs and thick sheaths dragging along the ground, while the female population stared and drooled at the sight.

Being so big was never easy, but life never was anyway. Balto was accustom by now to having several bitches _beg_him to breed them, and while he enjoyed the sessions, his heart remained with Jenna. His sons favoured the married life, with only a few choosing to be available to all bitches. Kodi was not one of them, having found his own special person to be with.

Dusty was a fellow teammate of his on the mail team, being the dog to take up the position behind the lead dog. Kodi had started out as a dog beside her, but moved up the ranks to lead dog, taking after his father as the team leader, while also developing a loving relationship with her. Nothing pleased Dusty more during a mail run than to see Kodi's giant balls swaying and flapping before her.

And so, that brings up this day's problem; Kodi and Dusty's first anniversary as mates was coming up, and Kodi needed to think of something to make it memorable. Their first time wasn't an option, since they already used it for when they consummated themselves as one. And while they both enjoyed sex anyway (Kodi had clearly inherited Balto's libido and stamina as well as his size), Kodi felt that simply mating on what was meant to be their first anniversary would be too much of a cop out.

Figuring that his parents would be able to help, Kodi headed over to their home, where they lived with Jenna's human masters. He was fairly certain they were home, since Balto's cum had been splattered in several places along the streets up to the house (public sex was a very casual thing in Nome, and Balto and Kodi took full advantage of it, proudly breeding their bitches in public view whenever they wished), and panted moans could be heard in the house.

Sniffing at the front door just to be doubly sure, and smelling his father's virile scent going strong, Kodi headed in through the dog door, which had been adapted to allow Balto and Kodi easily enter despite their ginormous genitalia. Once inside, Kodi looked around the home, standing in the hallway, remembering when he was a puppy and the house used to be his home as well.

A sharp gasp made Kodi look around, spotting the open door that led to the living-room. He quietly padded up, before poking his head in to have a look.

Jenna and Balto lay inside, resting beside the fireplace in a dog bed. Balto's massive balls were lying just to the side, unable to properly fit in the bed, while the male they were attached to was gently rubbing his paw against Jenna's pussy, but what really caught Kodi's eye was his mother's swollen stomach. While not as big as it usually was after she and Balto mated, it was still rather impressive, making her look fully pregnant again.

Clearing his throat, Kodi stepped in, while Balto and Jenna turned their heads to look at him.

"Oh, Kodi. We weren't expecting you today," Balto said.

"Yeah, I just thought I'd pop by," Kodi said, trotting up to them and sitting down, letting his massive sheath prop itself up against his chest while his balls settled under it.

"How's Dusty doing?" Jenna asked.

"Fine, fine. Well, a bit dazed after last night, but other than that..." Kodi said, before laughing. Jenna and Balto joined in.

"You and her...you really are a perfect couple," Balto noted.

"Yeah, I guess we are. Like you and Mom," Kodi replied, smiling at them. He sighed, looking down. "The thing is...I need your help," he admitted.

"Help? Help with what?" Jenna asked, getting out the bed and heading to Kodi.

"Well, you know that Dusty and I are going to have our first anniversary in a few days?" Kodi asked.

"Oh, yeah. I'm sure that'll be a special day for the both of you," Jenna said.

"That's the problem. I want to make it special for her, but I can't think of how to properly pleasure her in that regard. I don't want it to just be another day where we have a fuck; that just doesn't seem right. And even though my balls are as big as Dad's, and they're_biggest in the world...I'm just at a loss. How do I make it _really special for her?" Kodi asked, unloading all his frets on his parents. If they couldn't help him suss out a way to truly give Dusty a night to remember, then he had no hope.

Jenna thought for a moment. Kodi was clearly distressed about it, and he had always made a point of showing Dusty how much he loved her. Seeing her oldest son so frustrated at his inability to think of a solution, Jenna knew she needed to help.

But how? He's such a clever dog - if he can't think of something, then it'll be difficult for me and Balto, she thought. Kodi wasn't always one for grand, romantic gestures, that Jenna knew. The husky glanced over at Balto, wondering, her mind wandering over all of Kodi's other dates with Dusty; ones she hadn't experienced herself, but heard of from the two. That's when her mind went back to a short while ago, and an idea popped in her head.

"Hey, honey, do you remember that thing we were talking about a few weeks ago?" Jenna asked, looking at Balto.

Balto looked up, before answering, "Wait, you mean..." He found himself unable to finish the sentence, but whether he was embarrassed to, or just not able to put it to words, Kodi didn't know. Fortunately, Jenna was able to end his words for him.

"Yes. I think we should try it out now, and if it works, then Kodi can use it to pleasure Dusty," she said.

Balto looked at her with a raised eyebrow, before nodding in agreement.

"Then we best head upstairs," he said, getting out the dog bed himself, and stretching. Kodi noticed Jenna lick her lips at the sight, before Balto stood up straight, and walked out the room. Jenna and Kodi followed close behind as they headed up the stairs in the hallway, before entering the second door on the left in the upstairs landing.

Kodi looked around the spacious room they now stood in. He saw the large bed sitting at the back of the room with two bedside cabinets, while a desk with a vanity mirror stood nearby, across the room from a large wardrobe next to a chest of drawers on either side.

"How come we're here?" the husky asked, looking at his parents.

"I saw Rosy's father bring something up here the other day, and if we're going to do what we are, then it'll be really helpful," Balto said, walking over to the wardrobe and managing to pull the door open. He rummaged around in it while Jenna and Kodi waited patiently, before bringing out a rather large foot pump, with a long hose attached, ending in a thin nozzle. Kodi cocked his head.

"Is your plan to take her to the beach?" he asked, thinking his parents were going to inflate a beach ball.

"Well, it might work on the beach," Jenna said, walking over to Balto, who was very obviously starting to harden, his erecting tip standing a good foot from his sheath and still growing.

"Sure you want to try this? We do have other ways to help him," Balto whispered.

"But they'll get boring after a while - _this_could be fun any time," Jenna replied. With a grin, she licked along Balto's swelling shaft, coaxing more and more of the red flesh out of its furry home. Kodi watched in interest as his mother readied his father, observing her technique of hardening the wolf-dog, until Jenna had managed to finally bring Balto to his full, throbbing, humongous length, the gargantuan knot swollen at the base. She picked up the hose, and flashed a quick grin at Kodi, before inserting the nozzle into Balto's tip, much to Kodi's surprise.

Balto didn't show any discomfort at the insertion, and just looked at Jenna. She smiled at him, licking his face and asking, "Ready?" Balto could only grin back as he replied, "Do it, Jen."

Still smiling, and already feeling largely aroused, Jenna placed a paw on the foot pump, and started to press down on it. The three canines could all hear the gentle hiss of air rushing from the pump and through the pipe, before Balto fidgeted slightly as he felt the cold air flow through his dick.

Jenna continued to pump air into Balto, while Kodi watched in surprise. Then, Balto moaned, as, before everyone's amazed eyes, his already huge balls started to swell even larger! Kodi couldn't believe what he was seeing; his mother was inflating his dad's balls like a pair of massive balloons!

"Do you like it, honey?" Jenna asked, looking at Balto, even as his face started to contort with pleasure.

Still moaning, Balto huffed out, "Y-yeah, baby. Don't stop just yet. This feels...great," before giving a sharp intake of breath. Jenna complied, and started working the pump fasting, sending more and more air into Balto's rapidly bloating balls.

Kodi just watched in silence and disbelief, slowly bring a paw to run it along his own massive balls, wondering if he would feel the same amount of pleasure that was clearly flowing through Balto if he tried it. His balls twitched for a second, as if eager to try it as well.

The foot pump continued its job for another three minutes, Jenna gladly filling Balto's balls with air, before, when Balto's orbs now stood at least two metres big each, Balto panted out, "S-stop, Jen. T-that's enough." Jenna obeyed, removing her paw from the pump, before tugging the hose out of Balto's dick. Their son just sat where he was, impressed at what he had just witnessed, and truly amazed at Balto's now colossal, ballooned balls.

Just as amazed as Kodi, Jenna eyed Balto's impressive assets as she said, "Okay, well, that part of the idea worked out really well. Let's see if the second part is just as good."

Second?! Kodi didn't know how they could top this.

With a smile at Balto, and a quick wink over at Kodi, Jenna turned around a raised her tail, showing off her gaping pussy, still filled with cum, and ever needy for Balto's massive cock. Balto licked his lips at the sight of his favourite bitch's hungry pussy. With awkward movements, not used to the new size of his treasured balls, the wolf-dog approached his mate, and managed to mount her, directing his dick to point at her spade and push the first few inches of his tip inside.

"Ready for me, baby?" Balto asked.

"I'm always ready. Now, fuck me like a wolf - I want to be ravaged like I was in the streets!" Jenna replied.

The male grinned, gripping her hips harder, and shoved forwards. Jenna moaned, her walls stretching apart wide to take his length. The gargantuan monster of a cock slide in up to the knot, using Balto's previous orgasmic remains as lubricant to slicken its way. Balto moaned as his knot bumped against Jenna's mound - she had never been able to take the knot fully in one go.

"You feel just as great as always, Jen," Balto said.

"Shut up and fuck me, Balto!" Jenna yipped, her belly bulging with the shape of Balto's dick. With a smirk, Balto complied. He leaned closer to her, nearly smothering her back with his belly, and pulled back as much as he could, letting the slick friction of his shaft moving out cause Jenna's stretched pussy to spasm around the fleshy stalk. Once he felt he was back at a reasonable distance, Balto thrust forwards, and started to properly fuck her, slapping his knot against her hole with every forward movement.

Kodi watched as his parents fucked, used to the sight already. The only difference was, now Balto's bloated balls bounced behind him with every movement in an almost hypnotic fashion. Jenna was moaning in pleasure, her mind numbing over as climax tore at it. Except, Kodi could swear his mother looked more out of it than before. Could inflating Balto's balls really have that effect on her?

Balto grunted when another thrust proved ineffective to put his knot where it belonged. Jenna sure was a tight one, a bitch he would never tire of. The soft, wet splaps sounding out were practically music to his ears, the delight of knowing it was Jenna's spade and his cock making those noises with every eager collision of genitals. He had to admit, inflating his nuts was an amazing idea - at first, he wasn't too sure, back when Jenna first brought up the suggestion, but now he couldn't think of why he wanted to refuse!

Groaning and blubbering in pleasure, orgasm stripping her of any thought other than the amazing sex Balto was giving her, Jenna strained her neck to look back at the beast of a wolf-dog on her back, and barked, "Get that knot in! Tie me!"

Balto couldn't refuse. After all, she begged for what they both needed. So, with all his strength, he slammed his hips forwards, outright bashing his knot against Jenna's yielding spade. When all that movement proved effective to only force a third of the massive knot inside, Balto tried again. Another spine-jarring thrust, and a nearly half of the obscene glands had stretched Jenna apart.

Kodi cheered Balto on, shouting, "Yeah, Dad! Rip her cunt open!" His own dick was now throbbing before him, leaking pre-cum on the floor as he gently ran a paw along it.

Spurred on by his son's encouragement, Balto tensed his hips, tightened his grip, and resolutely rammed his body forwards. Jenna yelped and yipped and whined as Balto forced the knot in, stretching her apart wider and wider, and ending with the familiar, needed pop!

Groaning as Jenna's pussy and womb clenched around him, Balto continued to hump Jenna, his inflated orbs still bouncing around behind him, before he felt them tense up slightly. He knew his climax was coming. With a smirk, Balto brought his lips to Jenna's ear, and whispered, "I'm gonna make sure you're so big, our next litter could _live_in your belly."

"Do it! Breed me; I want your cum so badly, Balto! Fill my nasty cunt with your seed!" Jenna shouted, before moaning incoherently as yet another climax washed over her. How many was that now? She lost count after the fifteenth.

"My pleasure, my little cockslut," Balto replied. He hammered home three more times with quick, precise thrusts, and held himself there, howling to the ceiling. His massive balls pulsed visibly, as thunderous, pleasured-filled splurts sounded out, Balto's potent, abundant puppy-batter launching from his tip and into Jenna's bloating womb. Jenna howled with him, the twin noises entangling in the air as the husband and wife bonded once more.

But only one minute into Balto's enormous cum-splattered orgasm, another noise joined in. A loud, audible _hiss_sounded out, and, as Kodi watched, entranced, Balto's balls began to suddenly deflate at a fast pace, while Jenna's bloating belly started to swell even faster than before. The air that had inflated Balto's balls had been released once Balto had opened the floodgates, right into Jenna's womb!

The moment the entrapped air assaulted her already overstimulated uterine walls, Jenna lost it. A near endless chain of orgasms and climaxes rushed over her like a tsunami, the harrowing waves of lust and pleasure attacking her mind as it tried to process the sensations. It was just too good for her to comprehend.

Once Balto had finished cumming, and Jenna's brain recovered a short while later, the two both smiled at each other. By this point, Jenna's belly had inflated so much, both she and Balto were able to comfortable rest on top of it, the cream-coloured sphere easily reaching at least four metres in size, from both Balto's thick semen, and the mass of air.

Kodi's eyes couldn't be wider. Largely aroused at the sight, all he could muster to say was a quiet, "W-wow."

Jenna turned her gaze to him, and smiled over her sphere of a belly. Still able to feel the pleasurable gurgle of Balto's cum, she said, "Well, Kodi, it looks like our idea worked. And it felt...incredible!_Do what your father and I did to yourself and Dusty, and I guarantee that you too will have the best, and _biggest, anniversary you will ever have!"

Kodi nodded, and, once his cock had retracted into his sheath, he left, thanking his parents as he did so, leaving the two currently immobilised canines to their own devices for now. His mind still reeling from the amazing sight, and idea, he had just been privy to, Kodi headed to the boiler room.

Inside, Dusty was there, lying on her side. Hearing someone approaching, she looked up, and smiled when she spotted her mate. Kodi smiled back, walking over to her, before giving her a quick kiss on the lips.

Once he pulled his lips from hers (eliciting a sad whimper from her in the process), Kodi asked, "So, Dusty, you know how our first anniversary is coming up in three days?"

"Hmm, yeah. I can't wait for it, and for what you have in plan for us," Dusty said, happily nuzzling him. Kodi smirked.

"Well, meet me on my dad's boat in the morning, and I'll show you," he said.

"Oh, I'll be there, don't you worry," Dusty said. She grinned as she eyed his massive balls, already fantasising on what Kodi had in plan for them.

The next three days passed by rather slowly for Kodi and Dusty, both of them fully excited for the day of their anniversary to arrive. Luckily for them, they had the day off, and so, on the morning of the celebratory day, Dusty woke up in her and Kodi's home. But Kodi wasn't next to her. She looked around the room, unable to see him.

"He must have already gone to the boat," Dusty told herself, standing up and stretching for a second. She went over to her water dish and lapped up a few mouthfuls of the refreshing liquid inside, before munching down on some of the dog food left in her food bowl.

Having done all that, Dusty left the house. As she walked through the streets to head to the outskirts, she passed a few friends and teammates along the way, most of them congratulating her on her and Kodi's first full year of being mates. The husky just smiled and thanked them, before continuing on her walk.

Finally reaching the boat a full five minutes later than she wanted (Ralph just wouldn't stop talking), Dusty smiled when she noticed Kodi sitting on the ship's deck. Heading up the ramp, Dusty cleared her throat to announce herself. Kodi turned his head, and smiled at her.

"Hey, honey," he said.

"Hi, Kodi," she replied, nuzzling him. Kodi gave a low, soft growl, making Dusty shiver in delight. Pulling away from his warm fur, Dusty asked, "So, what did you have planned for us today?" She could barely contain her excitement at the prospect of spending time with her love.

"Well, I have to admit, I was pretty stumped at figuring out a way to make today extra special for us, so I asked Mom and Dad to help, and they gave me a great idea," Kodi said. Before Dusty could ask, he was already dragging a large foot pump out from behind a crate. Dusty looked at him, confused.

"What's that for?" she asked, trying to hide her mounting disappointment.

"It's part of what we're doing, Dust. Mom and Dad showed me something amazing," Kodi said, his dick starting to erect, a full foot poking out his sheath and still growing. He placed the pump before her, and added, "You see, Mom and Dad already wanted to try this out, so when I said I needed ideas, they decided to try it out. It was weird, but it was also cool."

Now Dusty was intrigued. "What did they do?"

"Well, you're not gonna believe this, but they...had Mom inflate Dad's balls, through his cock," Kodi said. His cock was now fully erect and dripping pre on the floor, the idea of doing what Balto and Jenna did exciting him greatly.

"They did what?" Dusty asked.

"I know. I was confused when I watched them do it, but, oh, Dusty, it was amazing. So I thought we could try it out," Kodi said. He grabbed the hose, and plugged the nozzle in his tip. With a grin at Dusty, he placed a paw on the pump, and demonstrated his point by pressing down on it. A hiss of air ran over the boat, and Kodi moaned as he felt the rush in his shaft, right into his huge balls.

Dusty just watched, amused, as Kodi worked the pump, but her eyes widened when she saw his story was true; already, Kodi's balls were starting to grow even larger. The surreal sight of Kodi inflating his own balls made her mind nearly shatter, but fortunately, Kodi snapped her out of it.

Pausing his pumping for a bit, Kodi grinned at Dusty, saying, "See? I wasn't making it up."

"I mean...I don't... You said your parents did it?" Dusty asked.

"Yeah. To be fair, they do come up with some...interesting ideas," Kodi said, shrugging. He smiled as he pushed the pump closer to Dusty. "Go ahead, you do it. Inflate my balls like my mom did to Dad," he insisted.

Dusty felt unsure, but at Kodi's pleading face, she couldn't refuse. She nodded, placing her paw on the pump, as Kodi sat back, giving her a small smile. Dusty smiled back, and pressed down on the pump.

Immediately, Kodi moaned, the air flowing into his balls again. Dusty kept pressing up and down on the pump, sending more and more air through the hose and into her husband's already large testicles, making them slowly grow larger and larger.

"Does it feel as good as your dad said it was?" Dusty asked.

"Yeah, it really does. Mm, I'm loving it, Dust. Keep it up," Kodi said in reply, moaning and groaning in pleasure. Dusty continued, getting faster and faster in her movements, sending more and more air through. She silently thanked her parents-in-law for coming up with this idea, watching as her work rapidly caused Kodi's balls to bloat and swell. Already, they were twice as big as they normally were, yet Kodi wanted her to keep it up. And Dusty wanted to know how big Kodi could get.

With the air tickling his sensitive shaft from the inside, Kodi was amazed he wasn't orgasming yet. He knew Balto said it was a pleasurable feeling, but the delectable sensation of air running through his shaft with every hiss of the pump was more than he ever thought it could be. Absentmindedly, he ran a paw along his growing orbs, feeling the skin swell out with every intake of air forced inside.

Finally, after five glorious minutes of tantalising pleasure, Kodi managed to sputter out, "D-D-Dusty! S-stop. I-I can't t-take anymore." Dusty lifted her paw from the pump, looking over her handiwork with astonishment. Just like Balto the other day, Kodi's balls had been inflated to two metres wide each, the monstrously sized orbs proudly resting on the floor beside their owner.

"Damn. That's amazing," Dusty whispered.

"Oh, the best part is still to come, dear," Kodi replied, panting slightly as his mind recalibrated. He tugged at the hose, slipping it free of his dick. Dusty had half-expected to hear a trickle of air rushing out his shaft, but grinned when nothing else happened. Then she realised what Kodi said.

"There's more?" she asked.

"Of course. Today is about you as much as me. You didn't think I'd just leave it at my balls being inflated like balloons, did ya?" Kodi asked. Dusty gave an embarrassed smile.

"So...what does come next?" the female asked.

"Turn around, hon. You know what I want," Kodi said, smirking. Slightly startled, but very willing, Dusty gladly turned away from Kodi, and lifted her tail to expose her tender hole to him. Kodi licked his lips, saying, "What a pretty sight. Makes me glad to know this is my cunt to ravage whenever I like."

"Don't you know it?" Dusty asked, with a giggle. She waggled her rump, eager to start. Drawn towards her, Kodi managed to stagger over, despite the awkward new size of his ballooned balls, and mounted, aiming his cock to her waiting pussy.

Leaning forward to whisper, Kodi said, "Happy anniversary, darling." With that, he thrust in. Dusty yelped, the intimate sensation of Kodi's massive cock spreading her vaginal canal apart and forcing itself in her womb flooding over her mind.

The male just groaned, his gargantuan knot pushed up against her, as-of-yet, unyielding mound, her belly bulging out from the rest of his cock. Kodi knew he would get the knot in - he had knotted her many, many times before, always refusing to let his seed loose inside her unless her walls were clamped around his bulging glands. It just simply took a little time for her to take it fully. The two liked it that way, though; even if Kodi forcing the bulge in had the possibility of tearing her apart, Dusty would never let him leave until they were both done.

Pulling back ever so slowly, savouring the delectable feeling of her walls massaging his dick, Kodi grinned down at Dusty while the female closed her eyes, the pleasure overflowing her brain. Then Kodi thrust forwards again, smacking his knot against her, letting his inflated balls bounce about behind him. They both moaned at that.

Just like Jenna the previous day, all Dusty's mind could focus on was the mind-shattering sex she was experiencing. Where before Kodi's amazing cock could make her see stars with every movement, the new bout of pleasure, just from inflating her mate's testicles, made her see galaxies! It was such a wonderful sensation, not having to worry or think about anything else, her mind enraptured in the delight.

Kodi could feel it. Deep in his ballooned balls, his next climax was building up. His addled, horny mind made itself up on the spot - knot the bitch, and unleash the greatest load he will have had yet. The husky smirked down at his tight partner, and slammed home. There was only so much room her lips could part, and the thrust proved unable to force them to open wide enough.

"You still such a tight one, Dust," Kodi moaned in her ear.

Dusty's mind recalibrated at the sound of his soothing voice just enough for her to reply, "Nice and tight, just for my big stud," before her voice dissolved into a long, dwindling moan as she was, once again, taken away from all other thought. The only thing on her mind, other than Kodi's expert fucking, was the tiny idea that inflating Kodi's orbs made him dicking her so much more pleasurable than before.

Another thrust later, and Kodi had worked just over a quarter of his knot in Dusty's stretching mound. He pulled back and shoved in again, spreading her apart just little over a third. Dusty just moaned and whined, while Kodi growled_possessively. He wanted to get his knot in; he _needed to tie her!

"Fuck me, Kodi! Spread me apart! I want your knot! I want that fucking massive knot locked in my little body!" Dusty screamed, only to end up squealing when Kodi's dick pressed down _hard_on her clitoris.

"My pleasure, bitch," Kodi replied, pulling back until he was almost fully out, and launching his hips forwards. A loud slap echoed out, but he still wasn't locked in. Growling in annoyance, Kodi tried again. He got closer, but still Dusty wouldn't part enough. "Shit, Dust, open up!" Kodi shouted, moving his hips back for another thrust.

Somewhere in her brain, Kodi's words triggered a response in Dusty's actions, and she widened her stance, just as her husband rocketed forwards. His red tower of meat slid in, the knot pressing up against her opening. The movement was stopped for microseconds, and ended properly a second later, with a loud, wet pop!

The two mates groaned, Kodi now locked deep inside her, making a massive bulge in Dusty's rump and belly from his cock alone. The male's bloated nuts bounced behind him, eager to unload. With his balls starting to tighten, his climax imminent, Kodi did what he had to do. He kept his grip on Dusty's hips, and humped her faster and faster. He wanted to make her orgasm once more before he showed her what he really had in store for her.

Dusty whimpered and _whined_as Kodi sawed into her, her body rocking back and forth with each forceful motion, before she screamed to the sky as her pussy spasmed and clenched around him once more, another orgasm rushing over her.

The male husky grinned as he felt her walls clamp around him, tightening their attempts to bring him to orgasm. He gave three more, final thrusts, before holding himself as flush with her rump he could, howling to the heavens as his balls finally pulsed and clenched. Dozens of splurts reverberated around them, the sounds blasting the two's ears even while Kodi's potent, rich cum flooded Dusty's womb. The uterine walls stretched out, the ocean of sperm Kodi was spilling into her causing her to bloat out.

And then, a minute into Kodi's climax, a loud, wet hiss sounded out. Kodi could feel it, the air in his balls rushing through his shaft to flow into Dusty's flooding womb. His massive nuts rapidly started to deflate and shrink back to their usual humongous size, while at the same time, Dusty's belly bulged and inflated at a sudden, increased rate.

Surprised at the extreme swelling, Dusty shouted, "Oh God, Kodi! I'm inflating! You're blowing me up like a balloon!"

Kodi grinned, and answered, "That's all part of it, sweetie. Just relax and enjoy it," in her ear.

"I am enjoyingggggggggaaaaaaaaaahhh!" Dusty said, her voice melding into a long moan as her belly grew bigger and rounder. She placed her paws on the swelling skin, feeling herself grow and inflate, much larger and faster than Kodi's cum alone could. It was an amazing feeling.

The constant flow of air battering her stretched insides suddenly made Dusty yell out in bliss, a chain of nigh-perpetual orgasms crashing over her. Her already sex-filled mind was suddenly overturned and shattered, reducing her to a howling, whimpering_mass of climaxing flesh, wrapped around Kodi's still _spurting cock as he filled her with cum and air.

Five minutes passed, before Kodi and Dusty calmed down from her orgasmic delight. Panting slightly, Kodi gently whispered, "Happy anniversary, Dusty," before nuzzling the back of her neck. Dusty moaned at his touch, before looking down. Both she and Kodi now rested on top of her belly, which was now inflated so much it could easily and comfortably allow them both to lie on top, standing a massive four metres in size. Kodi's balls dangled heavily beneath him, still throbbing as they nestled against Dusty's grey sphere of a belly.

When her mind had properly rebooted, Dusty moved her head to lick Kodi's cheek, saying, "That was amazing, Kodi."

"You really thought so?" Kodi asked.

"Oh, yeah. I want to do it again," Dusty replied earnestly, running a paw along her belly, feeling and hearing the _gurgle_of Kodi's cum as it filled some of her air-inflated body.

Before Kodi could reply, the two heard footsteps approaching. They looked up at the ramp, just as Jenna and Balto climbed onto the deck. The two older mates both stopped where they were, looking at the sight before them.

"Oh! I wasn't expecting this," Balto said, alarmed, but not disappointed. Jenna just smiled as she eyed Kodi, resting on top of his inflated mate.

"So, I assume you two both had fun, huh?" she asked.

"The biggest!" Kodi and Dusty replied together. Balto and Jenna laughed.

"Then do you two mind if we have some huge fun too?" Balto asked, spotting the foot pump sitting a little way away.

"Yeah, go for it," Dusty said.

"I agree. Do it, Dad. I want to see more. Give us a great show," Kodi added. Dusty nodded in agreement.

Smiling, Balto grabbed the foot pump, and inserted the nozzle in his dick, while Jenna started pumping it.

Once Balto's balls had been inflated to the same size Kodi's had been, Jenna took the hose out, and Balto instantly mounted her, fucking her hard and fast, letting Dusty and Kodi watch him breed his mate. His humongous balls bounced about with every movement, the ballooned nuts almost hypnotically begging for attention.

Finally, Balto worked his massive knot in, and howled alongside Jenna as he fired cum and air into her swelling belly, ending with Balto lying on top of Jenna, and Jenna laying on her massive gut, standing at the same size as Dusty's as she and Kodi rested on the grey sphere.

"Damn, Dad. You sure know how to fuck a bitch," Kodi commented.

"I'm sure you're just as good, son," Balto replied. Kodi laughed, nuzzling the back of Dusty's neck while she moaned. Balto did the same with Jenna.

After a few minutes, Dusty suddenly thought of something, and voiced it aloud to the others. "I wonder who can inflate their belly the biggest, me or Jenna?"

Hearing his wife's idea, Kodi thought of his own, stating, "Yeah. And I wonder out of me and Dad who can inflate his balls the biggest!"

Jenna smiled as she glanced at Balto, who gave her a grin. They were both thinking of the same thing.

"Well, there's only one way to find out," Jenna said, giving a wide and lustful grin.
