The changing of the seasons meant different things to different people. To some the cooler temperatures brought on a sense of sadness in that the party days of the summer were now behind them, while others felt a calm that the turning of leaves initiated. Some people had trouble adjusting to the shifting climate, while others thrived.

Bears, for example, happened to belong to the second group of people, who welcomed the chillier weather with open arms. Sure, there were quite a number of them who enjoyed their time in the sun - especially when given the opportunity to show off their bodies - but they all looked forward to the fall for one reason in particular.

Hibernation.

A tradition as old as time itself, all bears felt the urges to start preparing for hibernation arise well before the first snowfall, ensuring they'd be nice and plump by the time winter rolled around.

Bryan, for whatever reason, was never one of those bears. For as long as he could remember, the instinctual need to ready himself just didn't come, leaving him a bit out of sorts when the winter season rolled around. Normally a beanpole, he stuck out among other bears for his lithe appearance in contrast to the various bulky body shapes they all sported. When it came time to settle down and rest as snow blanketed everything? He was even tinier, at most sporting the thinnest layer of pudge that another ursine would gain from only a single meal. It didn't particularly bother him, per se, but the fact that he seemed to perpetually be the odd man out every year did confuse him.

His father and brother, however, looked like the kings of hibernation instead. During the summer they were statuesque Adonises, towering over other folks in the city with hundreds of pounds of brawny, bearish muscle mass that conventional clothing strained to fully contain - not that they lorded their size over people or anything. But come winter the pair were a couple of eating machines, completely flipping their bulk around and piling on fat like it was going out of style. It seemed so natural when their instincts kicked in, making them crave shoveling as much food into their greedy gullets as they could. Other bears would pale in comparison to the extreme weight they added to their frames in what felt like a short amount of time.

Bryan hadn't really been much of a witness to their multi-month binge - he usually dipped out after his typical weeklong visit - but it wasn't like he _couldn't_stay; his company understood the needs of all ursine species and allotted time off for him to accommodate them. While he knew he never needed it, he'd never think about saying anything in fear of his extended vacation being cut dramatically short and getting whisked back to work. He had hobbies to occupy his time over the break anyway.

But it was still nice to spend time with his small family - metaphorically speaking. Sitting beside him on his dad's broken-in couch was his brother, an absolute colossus of a bruin, so thick in stature that the distance from a bicep head to the end of a tricep measured wider across than his slender waist. He wasn't surprised by that fact considering how long that'd been the case.

Viktor couldn't seem to keep his eyes glued to the wide-screen television opposite from the two of them, occasionally flicking his gaze between it and his younger brother. "So, you joining us for hibernation this year?" His voice oozed with a slight tinge of hope.

"Eh, probably not considering the same happens every year. No matter how hard I push myself, I just can't gain weight to save my life, regardless of the time of year," Bryan shrugged, his head locked in the direction of the show on the screen. "Call it a curse or whatever, but I've grown to live with it. Gives me time to do things over the winter."

"Ah, shame. We'd love for you to join!"

Bryan grinned at his brother's enthusiasm. "You're really pumped about this, aren't ya?"

"Hell yeah, I am! It's probably one of the most fun times we've got all year," Viktor's laugh boomed throughout the room. His animated demeanour had his chest bouncing. "I really wish you could put on weight. We have a ton of fun, and I know dad would love having you around this year."

Bryan could only sigh at the remark. "Look, I'll tell you the same thing I say every year - if I miraculously manage to put on a promising amount of weight after the week I planned on visiting, I'll stay here and hibernate with you guys. That has yet to materialize in any fashion." While it didn't inherently dismay him that his body didn't function like other bears' did, he couldn't deny that going this long in life without any signs of progress wasn't annoying. To him, he seemed destined to remain the blade of grass in his family, dwarfed by the mighty oaks that his father and brother grew up to be.

"Hey, this could be your year!" Viktor nudged his brother, thoroughly in control of his strength after years of sustaining a size magnitudes larger than the lanky ursine.

"I highly doubt it, but I appreciate the sentiment."

"Hey boys, food's on!" Malcom called from the kitchen, the elder bear having spent the last little while putting a bubbling pot of stew together.

The call of food had Viktor leaping out of his seat, his heavy footfalls causing thuds to resonate across the hardwood floor of the living room. "Hell yeah!"

Seeing the lumbering behemoth of a bear acting like a kid in a candy store had Bryan laughing. "Jeez, you always act like you've never been fed before."

The trio of brown bears took their spots around the kitchen table, the difference in size between Bryan and the other men in his family almost comical. The two titans took no interest in savouring the meal, instead opting to wolf down every morsel available with barely a breath taken in between. And then there was him, quietly munching on his dinner. The other two seemed to lose their manners by this time every year but he paid it no mind.

"Man, I don't know if it's because you're getting better at cooking or because instincts are kicking in, but this stuff's delicious!" Viktor punctuated his point by licking his bowl clean before heading over to fill it back up for the third time.

"Well, I have had some time to practice," Malcolm chuckled. His eldest son reminded him a lot of himself at that age, to the point that his boy was practically the spit of him in spite of being the burlier of the two. His eyes then trailed over to his other son, glancing at the smaller bear drumming fingers against an empty bowl. "Hey, you good, Bry?"

While his immediate response would be to say that there was obviously nothing wrong, Bryan's body felt a bit odd after finishing his usual portion. Unlike what he remembered from years past he didn't seem as sated as what he should've been. It prompted him to utter a phrase he thought would've never come. "You know what? I don't think I'm full yet."

"Oh, it's happening!" Viktor cheered as he reseated himself.

Bryan scoffed at his brother, a wry smile contorting his face. "Relax, this is only a small second helping. I doubt it really means anything in the grand scheme of things," he absent-mindedly filled his bowl back up to the top, eliciting a gulp but not getting him to put some of the food back. "I'm not gonna be hibernation-ready like you guys will."

***

"Huh, I guess this is actually happening."

A week had passed since Bryan had initially taken on a double portion of dinner, which, unbeknownst to him, kicked off the start of his very first bulk. Every meal since then had him going back for seconds, with just yesterday being the first time he ate thirds. To be honest, it surprised him how ravenous he'd become in such a short time, though it surprised him more that his father and brother felt that way every year. He'd eaten more this past little while than he had the whole of last month!

The result of his overeating became rapidly apparent with how much his clothing started bulging out in every direction. His shirts - which used to hang loosely from his torso - now clung tightly to his swelling body, caking fat filling every article of clothing until there wasn't any room left to stuff, and then going beyond that. It forced the bottom of his T-shirt up to ride up his burgeoning belly.

That became the focal point of his attention, his hands gravitating to his growing gut as he observed himself in his room. Try as he might, he couldn't pull the hem of his shirt over his paunch now, the blubber too packed onto his midsection to allow it. In a way it felt... good - right, even. He obviously knew bears gained a ton of weight at this time of year, and it felt rather nice to experience something like that for once. The sensation of heaviness was unlike anything he'd ever felt in his life.

Having his arms wobble when he moved them in the air felt so alien to him that he couldn't stop staring at them as the fat jiggled back and forth. Also having genuine moobs was strange, with the ability to lift and watch them drop being something he played with.

And to think this was only the start of preparations! It'd barely been any time at all since he was rail-thin, and now he looked more than twice the person he used to be. If he were actually going to join his dad and brother for hibernation, that was a fantastic sign of things to come.

Maybe he'd celebrate his gains with a snack.

***

Two weeks had passed since the start of Bryan's bulking, and the bear hadn't slowed down in the slightest. His modest paunch had exploded into a full-on gut, one he didn't know he was capable of achieving. It was obvious as to why if one were to look at him - his food intake had skyrocketed over the last week, both in terms of the size and quantity of portions. Suddenly three meals a day wasn't enough, and they lasted a lot longer than they used to; well, their length started evening out as his ability to eat grew, allowing him to shovel food down his greedy gullet far faster than ever before. He'd become an eating machine.

It had an understandable impact on his attire as now his engorged belly hung out the bottom of his shirts no matter what. Not even trying to force them back over the dome of blubber worked as there was simply too much mass in the way. Of course he never tried to - that was what he wanted the whole time.

The trait was shared across all his tops, including the button-down he currently wore. It surprised him just how much it still fit him given his present physique, though the way the fastenings stretched around his corpulence told him everything he needed to know about the garment's structural integrity. The hole formed in between the buttons on his stomach was massive!

He grew transfixed on the development, watching the fastener squirm with every breath he took, his diaphragm forcing his gut to expand as he inhaled. His curiosity got the better of him as he observed himself after taking a deep breath. Slowly, but surely, his belly swelled, forcing the tension of the fabric to its breaking point before suddenly feeling the pressure instantly disappear, followed by the button being sheared off his shirt, bouncing off the floor of his room, and half-embedding itself in the wall.

Holy shit, he actually did it! He had no idea it'd occur to him so soon, but he was glad it did. His father and brother did similar things within a few days of stuffing their faces, which made him happy that he actually wasn't too far behind them after all. A satisfied smile stretched wide across his face, indicating his immense amusement at achieving such a task, though, it left him wondering what it would take to--

His stomach growled. Ah, he'd gone an entire hour without eating - how silly of him. Good thing there was an easy fix to that.

Bryan huffed as he made his way to the kitchen, still not used to the greater amount of effort needed to do so. The brief walk to another room signified that it wasn't just the one button that wanted to give up the ghost, but in fact his whole wardrobe teetered on the brink. Fluffy fat hung over the edges of the waistband to his pants, giving him ample love handles that bounced with every step taken, much like his flabby moobs. And his pants themselves didn't seem like they'd last much longer considering how much thigh each leg was forced to conceal. Tiny rips had already formed along various stress points to show as much.

But he paid it no mind as he rooted through the fridge, hunting for something he could shove down his throat. His hands immediately grabbed whatever leftovers happened to be within arm's reach and mowed down on them, the empty feeling in his belly barely subsiding, forcing him to devour more than he ever had in his life. The raging fire of hunger deep in his gut yearned to be sated.

His increased gobbling certainly had an effect on his clothes, which would've screamed in agony at the ever-rising volume of flab required of them to hold if they could've. The dramatic increase of calories taken in over the last little while caused his metabolism to escalate far more than he thought was possible, letting him digest his meals in a significantly reduced amount of time compared to when he was thin, and his second breakfast was finally making itself known.

One button couldn't handle any more pressure and promptly ricocheted in the other direction after being fired at the floor, followed by another as the mounting force brought on by all the soft lard led to the demise of his attire. The tears in his pants grew at the same time as the remaining buttons strained to keep the front of his shirt together. Neither of which were of great importance to him as he zoned out and continued wolfing down whatever he found.

More and more his pants split open, not only down the legs as his burgeoning thighs billowed out of the growing tears, but also along his ass crack as the pillowy mounds of flesh proved too much for the material to handle, going so far as to do the same to the briefs he somehow managed to slip himself into. His pants' destruction persisted until they shredded into ribbon confetti as he bent down to grab at something on the bottom shelf, gathering around his feet and leaving him naked from the waist down.

His shirt followed suit, the buttons having popped off at a far faster frequency until his front had been entirely exposed, which then saw his bloating back tear the fabric in twain as the swelling flab overwhelmed it. His arms were no slouch either, the piling fat too much for the sleeves to take and rendering the top useless as a rip along each caused both halves to unceremoniously fall to the floor.

It was only upon feeling a draft across his corpulent frame did Bryan finally take note of his state, though doing so without any terror like he normally would when he was smaller. He'd long expected this to happen, pleasantly surprised at how soon it ended up being. It was fortuitous that he'd satiated his hunger enough to check himself out now.

The first thing he noticed after running a hand along his tummy was how soft it was, both from his well-maintained fur and from the hundreds of pounds of fat he'd amazingly gained in no time flat. Well, it wasn't that impressive compared to what his dad and bro managed to pull off in the same timeframe, but it definitely meant a lot to him.

He'd gotten so thick that he couldn't stop fondling himself, entranced by his own lard as his hands migrated towards his massive ass cheeks. It elicited a gasp of delight out of him as he felt their enormity for the first time. That was him! While there weren't any chairs in the place that had armrests - for whatever reason - he knew he'd be able to touch both with his bulging rear end without any trouble at all.

And these moobs! His arm fat jiggled as he cupped his chest, thoroughly enjoying the fullness of each mound of fat as they squished between his fingers. It had his breathing intensify, the sensation of this kind of sheer weight belonging to him being felt for the first time in his hands. Heh, he'd have to chalk it up to his brother - the bigger bear was absolutely right in saying this was awesome.

His groping had an unintended side-effect, however, in that he'd become achingly hard as a result of manhandling his own lardaceous body. It coaxed an embarrassed huff out of him before he shook that out of his head. Why wouldn't he like this? He was a bear, and bears were meant to be big. So what if he got off on his own form, that was part of the experience. That was what he wanted!

Instantly his hand jumped to his throbbing crotch rocket, though not prepared to deal with the massive fupa that had formed as a result of his continual snacking. Even then he couldn't prevent a moan from leaving his lips, his hands caressing the blubber and only making him harder. The tip of his shaft dribbled a constant stream of pre that coated his thick fingers as he stroked his member as best he could. Damn, he wished he could've done this a whole hell of a lot sooner than now.

The intense feeling of arousal had his legs buckle beneath him, sending him hurtling to the ground, his flabby ass absorbing the impact. His nostrils flared from the overwhelming pleasure his newly-gained fat gave him, forcing air from them harder the hornier he grew. He couldn't believe how much he was getting off on this!

His bobbing reached a fever pitch as he bit his lower lip, his one eye half-shut. Tension forced his body to double over the closer he got to orgasm. More and more he pumped his cock, the head drooling precum like crazy. It wouldn't be soon before--

A low cry emanated from his mouth as he let his dam burst wide open, blasting a couple sticky ropes of cum against the underside of his gut. That was incredible! It might've ended just as quickly as it started, but that was easily the best release he'd ever had. It left him panting hard from the exertion he did to pull off the feat, but it was well worth the effort needed.

A happy grin adorned his face as he laid back against one of the fridge doors. "Yeah okay, I totally get it now."

***

Three weeks of stuffing his face left Bryan with a gut that balled out at least a foot from the base of his torso, and he couldn't have been more thrilled with it. It all hung off his frame with a force that should've kept him grounded to a seat or the floor, and it had him wondering how he still managed to stay upright given how much weight he must've gained thus far. The solution to the puzzle eluded him still, but his regular inspections presented something else that caught his attention - he'd grown taller.

Truthfully it wasn't by a whole lot - just a few inches at best - but the fact that he'd gained height completely astonished him when he discovered it. That _had_to have been how both his dad and brother got so tall! Well, his father had been a towering bruin for as long as he remembered, but his brother was far closer to his height for years. He now distinctly remembered that it was immediately following the first hibernation the older bear took part in - that being the year he graduated high school and left for college, leaving his dad and big bro at home - that the changes rolled in, leaving him without words when he returned to see his family in the new year. It was, uh, quite the adjustment for sure.

But now he was on the same path, growing taller to help accommodate more chub across every part of his burgeoning frame. Oh, this was exciting! He grabbed his belly and lifted it as high as it would go before letting it drop, positively adoring how much gravity affected his heft. It felt so good to be huge.

His wardrobe was well past inadequate now, with not even something like sweatpants able to contain the majesty that was his gigantic ass. His girth was too fucking mighty for conventional clothing to envelop him now. The thought had his pride swell in his chest, his hands groping his heavy rear as he let a moan escape from his lips. Heh, he never thought he'd make himself so horny.

It had one hand reach down for his stiffening cock, only to freeze in place when contact with his fingers was made. That couldn't be right... Another tentative stroke was given to his fleshpole, his mouth agape as confusion wormed across his face, but the initial sensation had proven correct - his junk was much bigger, as if growing along with the rest of him. Fucking awesome!

Bryan could only laugh in disbelief at the revelation, his self-esteem getting a much-needed boost. Man, he was so much bigger than he was before, making his past member look meagre in comparison. It now filled his large hand completely from base to tip with some of his rod poking out past his index finger. Goddamn, his brother had this happen too? Maybe he should've forced himself to eat a ton years ago.

Stroking his pillar with both his hand and his tummy felt phenomenal. He couldn't get enough of the plush flab massaging his length, or how his cock contoured around the underside of his brown-furred belly far more than it used to. It put a huge grin on his face as he reveled in how much bigger he'd gotten all over.

More and more he pumped his cock, his hips aiding the process by thrusting into his hand, which effortlessly glided along the length as though friction ceased to exist. His balls, too, had plumped up, absolutely roiling with seed that their new grapefruit size desired to expel. Finding purchase on his lardaceous gut, his other hand, kneaded the flab that accumulated there, feeling just how enormous he'd gotten and making him visualize how immense he wanted to be before hibernation started. He'd never actually witnessed what his father and brother looked like at that point, but he could only imagine.

A few snorts signaled the start of his climax, his breathing growing laboured the more he fucked his hand. The feeling of such a large prick belonging to him still bewildered him, but it only turned him on more that it'd be even bigger soon enough. How big could it be? He wanted to know his limits, hoping they weren't too drastic. While this was his first hibernation, he wanted all the benefits that the rest of his family gained.

And with that he finally came, a long moan rising from his throat as he splattered the underside of his sagging belly with more spunk than he used to produce in a week, even jerking off multiple times a day. It thrilled him to his core that he'd become so productive now.

He fell backwards onto his bed, the frame still able to support his ample rear just fine, though clearly unhappy about it with how much it groaned from the sudden addition of weight. His release left him reeling, licking his lips both in appreciation for his current afterglow as well as anticipation for how much better his orgasms would be in the future. Hell, this all happened only after a few weeks, and he still had months to go before they finally rested for the winter. With his dad keeping the kitchen stocked he had access to food no matter when he went in, letting him stuff his face with whatever delicious thing had been cooked up that day.

It was then that he promised that he'd push himself as far as his body would go, whatever that looked like. He was going to make his father proud.

***

A month of non-stop gorging had taken its toll on Bryan, who couldn't be happier with how his progress had been turning out. Every single body part had bloated with sumptuous chub as his unrelenting appetite fueled his binging. He'd grown so engrossed with himself that he made sure to inspect himself whenever he had downtime, which became increasingly uncommon as time ticked on.

So much weight had piled on his growing frame, to the point that his belly alone weighed more than he used to, though with how far the adipose hung from his torso it seemed like his gut was keen on doubling that. He'd let it, of course, as his desire to swell with soft fat superseded anything else at that point. Heh, he'd really gotten into the hibernation spirit!

Not a single part of his corpulent form had an edge on it - from his blubbery thighs that fought for what little room was between them, to a pair of bloated moobs that rested on his butterball belly, to his curved face that adorned itself with triple chins. Rounder and rounder he grew, day in and day out.

There were some adjustments he needed to make as his body inflated with lard - as well as his rising height, which he still had no real answers for. One of the first things he noticed having troubles with was sleeping, in that his bed often felt ready to give out if he didn't carefully manoeuvre himself in such a way that spread his weight around. Sure, he could just use his own lardaceous flab to rest on, but he didn't think it could beat the comfort that his old mattress gave him. At least, for now.

Being taller was also weird as his higher point of view took some getting used to. He barely noticed it in his day-to-day routine, but all it took was one moment where his brain said something was off for it to be the only thing he focused on, which then took away from his eating time. His rumbling stomach didn't like that.

But he adapted - he honestly had no choice but to. His father and brother acted like the near ton of weight they'd put on barely fazed them, going along their day as they waddled from room to room, their corpulence doing little to hinder what years of experience built up. Those guys were experts in bulking up, and he wanted to emulate them to the best of his abilities.

That came sooner than expected. He'd situated himself at the kitchen table, polishing off what would've normally been three weeks' worth of chili in just under fifteen minutes, when right after letting out a sigh of relief he heard an abrupt cracking noise, followed by a sudden change in view as he plummeted to the ground. The fall momentarily stunned him, though he quickly managed to regain his composure as he surveyed the scene.

He'd collapsed the chair he sat on, one that'd supported his weight for years. It was only then that he realized how he never saw the other two bears dining in the kitchen, thinking that was the reason why. It now made sense why he remembered one missing a few years back.

But the fact he did it? That put him over the moon! Carpentry built to last decades couldn't compete with ass cheeks bigger than watermelons, creaking ever larger the more he engorged himself. It was a proud mark of progress in his books.

And it also had Bryan hard as a rock. His cock now reached past his belly button, throbbing with need that gnawed at him as much as hunger did. It amazed him that, not only did he have little downtime between wanting to eat again, but also between orgasms - he'd jerked himself off when he rolled out of bed, and it wasn't even noon yet!

He panted as his hands naturally found their way to his shaft, his arousal only skyrocketing further as he felt how he needed both extremities to envelop the quaking cockflesh. Cum tanks the size of his head churned with bearbatter waiting to be blasted. He huffed, beads of sweat running down the sides of his face and matting whatever dry fur they found. Any exertion he did at his tremendous size got him panting hard.

His body jiggled as his pelvis thrusted, helping get him off when flexibility was becoming an issue. It'd been a good system he'd developed to aid with his cravings. Despite his surging pillar, sight of it was still impossible thanks to the hundreds of pounds of bulk that consumed his view, not even craning his neck over his flabby chest did any good other than shaking the rolls accumulated on his chin.

But he didn't need to see his pole in order to feel it, especially the way it actively pushed against his heavy gut. He thought he'd become an absolute tank after putting on what felt like a lifetime's worth of weight in mere weeks, but the fact that his own rod could withstand his immensity triggered something deep down that only excited him further. His hands sailed along the slickened flesh as he coaxed himself to orgasm, finding both the barrier to climax and the amount of pleasure felt having both increased as his endowment flourished along with the rest of him. God, it felt good to be big.

The broken pieces of furniture didn't even bother him as his bloated rear end cushioned whatever might've otherwise felt uncomfortable. Not like he even noticed with how much his rolls undulated with every motion, his ass jiggling as he fucked the underside of his belly.

It struck him just how much he'd grown to love his size in such a short amount of time. His natural instincts had all but taken over at that point, he figured, as even_thinking_ about being this huge wasn't something that happened to him before. But he didn't want to just stop where he was now - he wanted more.

The craving pulsed throughout his body, electrifying his nerves from head to toe as he edged himself ever so much closer to release. Pressure built up in his roiling nuts, his prostate forcing his taint to bulge out as the pace of his hands quickened. Translucent pre oozed from the tip of his dick the faster he bobbed along it, practically begging to fire his load.

His body answered his prayers in a volley of ropes shooting from his cumpipe, both against his corpulent trunk as well as showering down in the area in front of him. He groaned in delight as the sensation of emptying his fattened balls washed much-needed relief over him. An increasingly dwindling number of things felt better than stuffing his face these days, but this always would.

Arms that naturally hung low thanks to the ample fat caking them positively succumbed to gravity once his energy had been drained. But that was welcome as he basked in his afterglow, a contented grin spread across his face. He nearly would've fallen backwards had he not caught himself, though trying to support all his wiggling mass might end up being more than he was capable of at some point. He hoped that came soon.

***

Shuffling his feet through the house became Bryan's go-to method of movement, his legs somehow still able to advance in a linear fashion after a month and a half. He didn't mind so much as it gave him ample opportunity to feel his fatty thighs rub against one another, sending ripples of pleasure that excited his girthy shaft.

Speaking of which, its natural state of being at this point was throbbing hard at all times, deluging him with tons of horny energy that he regularly indulged in. He was only following the other bears' example as both of them didn't have any issues cranking one out whenever they felt like it. If it felt good, why bother fighting it?

And as much as he'd have liked to entertain his sexual urges at that moment, there was a far more pressing hunger to sate that commanded more attention than his pole ever could.

His stomach roared for food, with him having the gall to have last eaten more than fifteen minutes ago. It wasn't his fault - he was playing a game and got so engrossed in it that he forgot; it honestly amazed him that he still had that capability even at his tremendous size.

Yeah, sure, both his father and brother still had hundreds of pounds of fatty bulk over him, but that still meant nothing about him could be considered small anymore. His mind reached back to memories of when he saw other bears getting ready for hibernation, but that happened around this time and he far outpaced them. Hell, even his body a few weeks ago would've made them look shrimpy! Not bad for a guy who stood out for being small.

His wandering mind left his body on autopilot as he made his way to the kitchen, the flesh knowing exactly what it wanted. He often found himself daydreaming as his ursine proclivities pretty much made everything associated with stuffing his face instinctual, though he might now need to pay attention to his surroundings more with his skyrocketing weight.

Completely breaking him out of his imaginative daze, the corpulent bear found himself wedged in the doorway to his room. It wasn't like when he helped move his bed through the entrance a few years back, having to turn it to fit it through - he was stuck, with his lard preventing him from simply backing out.

A rosy blush crept onto his chubby cheeks, having never been in this situation before. He knew what he had to do to get out of the predicament, but the thought had him cringing. Crushing a chair was one thing as it could easily be replaced, but the doorframe? That wasn't as easy.

Nevertheless, he knew he had no choice in the matter but to proceed. It was a struggle, far more than he anticipated it to be, but he eventually prevailed, the act actually made simple thanks to the flab that got him caught there in the first place. He quickly learned all his lard had quite a lot of momentum when in motion.

Heavy footfalls thundered to the site from a nearby room, the things hanging on the walls slightly shaking due to the vibrations created. "Hey, Bryan?" Malcolm called out, a curious expression crossing his round face. He stopped when he noticed his son merely barreled through the doorway and chuckled. "Oh, _that's_what the noise was! Okay."

His father's casual attitude toward the accidental destruction had Bryan a bit surprised. "Wait, you're not upset that I broke the door frame?"

Malcolm shook his head, his many neck rolls jiggling in the process. "Nah, it's like with the furniture. They've been destroyed so many times now that I stopped caring ages ago. I just use them as a reminder to make them wider when they get repaired. So go nuts and get as huge as you can!"

Bryan wasn't about to look a gift horse in the mouth. "Uh, alright then!"

"Oh," Malcolm's face lit up, "that reminds me..." Gently he pushed his son along into his increasingly cramped kitchen, the room designed specifically for big bears and yet still feeling on the small side. "Yes, they're here!" He plodded to the front door, fairly gracefully considering his gargantuan size, and deftly pulled in a stack of boxes that reached taller than him.

That was the most pizza Bryan had ever seen in his life. "Holy shit..."

"Yeah, woke up late so I had to think of something quick." In spite of his fat alone weighing almost two tons, Malcolm's innate strength still remained, making something like carrying the food to the table nearly trivial. He then grabbed around a third of the pile for himself. "This will probably be a good amount to start me off with. You can go ahead and start on the rest."

"What about Vik?"

"He's sound asleep, don't worry about him," Malcolm stated as he carefully waddled past his son. "Knock yourself out!"

Bryan watched his dad waddle out of the room, that corpulent ass jiggling with every awkward step. His eyes went as wide as saucers when he realized just how massive each cheek had to have been, in complete awe that such a thing was even possible, maybe even possible for him.

A growl from his stomach brought him back to reality. He snapped himself out of his daze with a shake of his head, his neck rolls squishing together as his nose directed him toward the fresh pizza. So many different aromas assaulted him at once, letting him know right away his feast consisted of a variety of options to choose from.

The box on top contained a standard pepperoni, not really his favourite but his hungry soul demanded to be fed. He gingerly grabbed a slice, careful to not touch the molten-hot cheese, and slid it down his greedy gullet after only a few seconds of chewing. The heat from the toppings thankfully didn't affect his mouth much.

His feeding continued even after several pizzas had been devoured, far more eaten than several parties he'd been to. And yet that still wasn't enough to satisfy him.

At the rate he was growing, he didn't even know if every slice delivered would settle the raging inferno of hunger in his gut. Maybe for now he'd tap out after eating half of what was left, but the story would be wildly different a month from then.

He couldn't wait to see what he was like at that point.

***

After two whole months of non-stop binging, Bryan hit the point where he didn't go anywhere without something to snack on. His hands were perpetually in bags of chips and pretzels if meals weren't readily available, though meticulously ensuring his fingers remained free of any food residue. Hey, he might be focused on stuffing his face, but that didn't mean personal hygiene was thrown out the window.

Every single activity he took part in since starting preparations now included shoveling junk food in to keep up his necessary caloric intake. At least watching television didn't require much effort outside of sitting on his increasingly wider ass, but finding something he actually wanted to see was still a pain.

It amazed him that his father's couch could hold a man of his immensity - having grown exponentially to an astoundingly solid two tons - but it made sense given how both his old man and older brother regularly shot past that mark every year. He swore he must've remembered his dad saying something about reinforcing the sofa, being one of the only things he used regularly enough at this time.

The other thing that floored him was the fact that he took up so much more space than he used to. It was incredibly obvious considering what he'd been doing for the last couple of months, but there was a stark difference between thinking about it and witnessing it for himself. Each cheek weighed more than he used to and needed more than one cushion to accommodate it, his whole rear end swallowing up one side of it and pushing any excess bulk over the arm rests. None of it registered as painful in any way given how plush all his fat felt.

One of the biggest - and strangest - beneficiaries of his unrelenting feasting was his shaft, which now sat closer to his original height from drooling tip to musky base. The monstrous schlong was thicker than his leg used to be, both hands essential for pleasuring himself now. Were they not already in use to keep his fat-laden cheeks packed with food, they'd be all over his cock.

Slow, plodding steps resonated through the room as they partially drowned out whatever was happening on the screen, with him instantly recognizing their owner as his brother, likely waking up from one of many naps taken throughout the day. He couldn't blame the older bruin as he felt himself dozing off more than he used to, not that sleeping so much was a bad thing, of course; that was expected of him!

"Oh man, am I starving!" Viktor yawned as he scratched his overflowing belly apron, the bottom of which brushed along the floor. He'd effortlessly made it to nearly three tons of sumptuous lard, faster than he managed to do both last year and the year before that; it was a high he rode for several days up to that point. Past his puffy chest, however, he saw his brother looking smaller in comparison to him, but no less as remarkable. He couldn't stop a grin from stretching his rounded face. "Dude, you're fucking massive!"

"Uh, what?" Bryan's lardaceous head snapped in his brother's direction. He felt the remark to be a bit ridiculous when looking at the gigantic ursine off to his side. "You're objectively bigger than I am."

"True, but I had a good foundation to begin with," Viktor chuckled, running his sausage-like fingers along his soft belly. "Compared to where you started, you came a long way. I mean, I had tons of practice doing this while you haven't, and you're still keeping up!"

"I mean, I guess so." While Bryan still looked at the results the two of them put up, there was no denying that he easily dwarfed his former size by several magnitudes.

While his normally jovial nature kept the smile on his face at most times, it suddenly dropped off Viktor's face when he finally noticed the leviathan erection his brother sported. It forced the younger bear's apron to flow around it, the lard having to obey the rigid spire's design. That got his own endowment rising to attention, his now doing much of the same. There was only one thing on his mind now. "Oh, hey, lemme help out with that."

Bryan didn't have a clue what his brother was referring to, his focus was on the fact that his fingers didn't feel any more food within reach. "With... my empty bag of chips?"

"No, your dick."

If Bryan's eyes could've popped out of their sockets, they would've when he heard that. It was only then that he noticed how the older bear's body displayed arousal for all to see, that gigantic schlong putting his to shame. How was his brother so hung?! "I'm sorry, what are you asking exactly?"

"Dude, I'll totally suck you off!" Viktor's smile returned as quickly as it faded.

"You are extremely nonchalant about this."

That only got Viktor to laugh. "Well, you would be too if you did it as much as dad and I did. Trust me, you're gonna love it!"

"I, uh... will take your word for it." Suddenly being thrust into this situation had Bryan's brain in overdrive trying to process everything, the gears spinning as he wondered how all this happened in practically the blink of an eye. Ultimately, while he hadn't thought of his family in a sexual light - ever - his enthusiastic arousal just about jumped at the chance to be satiated. "Alright, I guess if you're good with it then."

"Of course I am! There's no way in hell I'm turning down a free meal," Viktor's flabby form wobbled as he made his way over to the seated bruin, brown fur nearly blending in with the fabric of the cushions.

The casualness of the older bear's demeanour painted an amused, if detached, grin on Bryan's face. He watched as the other ursine waddled over to him before letting all that tonnage hit the floor, face now in line with the head of his pole. The immediacy of the act certainly caught him off-guard.

Viktor, on the other hand, was well in his element, his large hands already caressing the other bear's throbbing prick and coaxing a thick volume of pre out with every careful ministration. He could see his brother's inexperience and wasted no time. As quickly as he could, he slathered his tongue all along the mushroom head, making sure to lap up as much of the preseed as he could before shoving his mouth around it entirely, sealing off the cumslit from the outside world. From there he deliberately stroked along the turgid bearhood with the deft hands of a sexual master, eliciting growls of pleasure from the smaller man, and feeling the telltale signs of arousal peaking over the edge.

The inundating pleasure brought on by his older, larger brother had Bryan on his metaphorical knees, his balls pulling up to his flabby crotch after barely any time passing at all. He moaned harder than he ever had in his entire life thus far. In a fraction of a second what felt like litres of his potent ballbatter erupted from his dick, splattering the back of the other bruin's throat and washing down to that awaiting gut. He felt at the mercy of his brother with how incapacitated his release made him.

And yet Viktor remained calm and collected in stark contrast to his younger brother. He masterfully guzzled down all the spunk blasted into the back of his mouth, his nostrils flaring as the other ursine's musky stench hit his nose, only experiencing it for the first time. The smaller man never used to smell this good!

By the time all was said and done Bryan was a flustered mess of emotions, barely able to put together coherent sentences for a few moments as he gathered his bearings. "I'm so sorry, I didn't mean to shoot that fast!" He sputtered.

"Nah, dude, it's fine. These things get super sensitive when they grow. You just gotta get used to it," Viktor licked his lips of any lingering cum before managing to push himself back to his feet. He might be positively caked in tons of soft fat, but that didn't mean he'd lost an ounce of muscle mass in the process. "You feel like returning the favour?"

"Um..." Bryan gulped, his mind still reeling from the whole event. "I don't know if I'm quite there yet."

Viktor only smiled, patting his brother on the belly apron. "Hey, that's totally cool. You gimme a holler when you want your own meal replacement." With that, he waddled his way to the kitchen, looking to still top up despite intaking what had to have been a bathtub's worth of cum in minutes.

Bryan only just managed to regain composure, though still panting from what was easily the greatest orgasm of his life. From his brother, no less! He couldn't believe that--

Wait, did his brother and his father... How long had they been doing that with one another? Was that actually a thing? Clearly it wasn't an issue in the slightest for either of the other men. Hmm, was he okay fooling around with his family? Did all bears do that? If it's part of the preparations then he supposed it wasn't that bad.

Hibernation turned out to be way more involved than he anticipated it to be.

***

Three months. It'd been three months of Bryan perpetually eating at his father's house - every day stuffing his rotund face, every hour devouring whatever he could get his hands on, every minute ensuring his mouth was continually busy, every second doing his absolute damndest to quell the fiery hunger raging in his ever-expanding gut.

That became an increasingly difficult prospect as time kept moving forward. He was an eating machine at that point, but trying to sate his needs felt impossible. It didn't matter whether he scarfed down burgers, milkshakes, or even burritos as big as his head, he downed it all without trying and always craved more.

It started making him wonder how his brother and father managed to grow as much as they did. He alone was polishing off what felt like what would've been years' worth of food for him before in only a few moments, his bulging cheeks packing in multiple meals without even attempting to taste them. The only thing he could focus on was how hungry he was.

All his glutting had definitely paid off as his gains had been astronomically exponential, far beyond what he predicted he'd have made in his first year. His initial guess was at least a couple hundred pounds at most, but the knowledge that the other men would encourage him whenever they got the chance to made him think that making it past one thousand pounds was possible. He proved that incredibly fast, shocking him to his core. Well, if that was so easy, where would he end up? How heavy could he realistically get?

Four tons. Bryan weighed four fucking tons of jiggling bear fat. Well, that wasn't entirely true as a shaft that gave telephone poles a run for their money jutted out from his lardaceous crotch, leaking with need as his plush rolls continually assaulted the sensitive flesh. Its diamond-hard demeanour kept it essentially perpendicular to his torso, weighed down by all his flab but simultaneously forcing it to flow around him.

While that might annoy someone else trying to gain weight, he didn't mind in the slightest as his enormous gut still brushed along the floor in spite of the girthy spire being such an impossible obstacle to deal with.

All that undulating mass should've spelled the end of his mobility until the springtime, but somehow his body adapted to the additional lard by making him taller. That at least spread it all out so that not one part of his body became too burdened, but it still didn't explain how he could carry it at all. He'd have to make a mental note to ask why it was possible.

A string of heavy footfalls thundered louder and louder as they drew closer to the kitchen, heralding the family patriarch's entrance, grinning as he watched his youngest son clean the last scrap of food from the double-wide fridge. "Oh, I guess I got here just in time then!"

Bryan whipped his head around when he heard his dad's voice, his plush jowls jostling in the process. "Just in time for what?"

Malcolm only laughed. "Why don't you come see for yourself?"

Interest thoroughly piqued, Bryan followed his father to the back of the house, surprisingly moving faster than the snail's pace he'd have imagined someone of their collective corpulence would carry on at. There was no getting away from waddling, however.

Waiting for the pair of blubbery bruins was Viktor, who sat his fat ass on the ground, gut taking up all the room between his legs as it pushed out several feet from his frame. A pair of saggy moobs adorned his monstrous belly. "Oh, there he is!"

Having never before seen the mysterious room before, Bryan's eyes darted in every which direction, taking in everything he could. "What the hell is going on here?" Whatever this place was, it was spacious, easily able to house the three of them in spite of their combined sixteen tons of ursine bulk. A lone control panel was mounted along the far wall opposite the doorway.

"This is how we cap off our preparations!" Malcolm beamed, ambling over to the console. "Eating normally only takes a bear so far, so I had this room installed to _really_boost our gains."

"Trust me, you're gonna love this!" Viktor practically bounced where he sat, his copious amounts of rolls jiggling as he did so.

"Love what?" Trepidation was all Bryan could feel, though he knew for a fact neither his dad nor his brother would do anything to actually hurt him. His anxiety flared once more when a hiss sounded out above him. He wasn't quite fast enough to glance at what made the noise, but he saw what the result of it was - three tubes dropping down from the ceiling. "Wait, you have hoses to feed you? That's a thing?"

Viktor could only laugh. "Welcome to the future."

"Okay, so," Bryan shook his head, the weird room giving him further questions that boggled his mind, "why only do this now? Why not use the hoses right from the get-go? I'm sure we'd have reached this size months ago!" To emphasize his point he slapped his butterball gut, sending a ripple across the front of his belly.

"We'd be overwhelmed in a heartbeat if we did. You gotta build up your appetite in order to really appreciate what's in store for us," Malcolm scoffed. "I mean, if someone could actually pull it off I'd be the first in line to see it!"

The unexpected proposal didn't sound so bad to Bryan, who flicked his gaze between the older bears. "So, what's on the menu then?"

Malcolm needed a moment to remember what he had loaded in the many, many tanks stored for this exact purpose. "Lemme see, there's chocolate fudge, peanut butter, melted ice cream--"

"Don't forget protein powder!" Viktor interjected. "Gotta make sure your body still gets everything it wants."

"Ooh, almost forgot!" With a speed that belied his massive size, Malcolm flipped another switch and observed sections of the wall recede, allowing another set of tubes to protrude toward the middle of the room.

These didn't look the same as the others did, and Bryan had a hard time discerning their purpose. "Okay, so--"

"They're for our cocks," Viktor stated matter-of-factly.

Suddenly all the pieces fell into place. Bryan watched as the other two situated themselves appropriately - deftly affixing the hoses to their bodies as they'd done many times previously - with his father in the process of getting the ultimate gain train up and running. It got him to jolt to where his tubes were located, fumbling amidst his tonnage to get them in position before the activity started.

In an instant the sound of machinery whirring to life resonated through the walls, muffled by whatever material was used in the construction. Barely a moment went by before a thick slurry of the things his father mentioned - as well as a few other foodstuffs he noticed - rapidly made its way through the tubing and directly into their awaiting mouths. It had him moaning over the hose in his maw to have his rumbling furnace of a stomach get the meal it so desperately craved.

And amidst the commotion of the feeding the suction of the tube sealed around the first third of his cock started, immediately inundating him with a pleasure he never knew existed. His inexperienced rod spasmed at the intense stimulation, his hips uncontrollably bucking through all his growing fat. It barely took him any time to blow his load and shoot virile bearbatter into the tube by the bucketload.

The same thing was happening to the other two, even if Bryan couldn't quite pay attention to them. Viktor positioned himself as close to the nearest wall as he could, his swelling ass cheeks rising along the vertical surface like dough.

Malcolm was much the same, though his position of choice seemed to be on his back, his cock standing straight up in the air like an obscene monument to hedonism and gluttony. His body bloated out with every gulp he took of the calorie-dense fluid, his fat billowing out like lava as it swallowed more and more space around him. Throughout it all he was in his element; nothing to do now but get huge and cum.

The program created to control the process had been perfected ages ago, calibrated down to the tiniest detail to ensure whoever used it wrung out as much potential size out of the procedure as they could. It was already known that the users would be incapacitated from the unrelenting pleasure brought upon by growing and busting the fattest nuts on the planet to really control anything, so it needed to collect data taken by numerous sensors that fed back a ton of things.

While the bears obviously needed to sleep, the code was sophisticated enough to detect when someone was merely snoozing versus when they reached the state of hibernation, making sure that the feeding and collection apparatuses weren't retrieved early. That allowed for as endless as growth as possible before the inevitable wispy threads of deep sleep took over and let them slumber until spring.

With a fire of passion burning inside him as he made the initial preparations before his sons came to visit, Malcolm more than doubled the amount of tanks he had in the previous years, really wanting to push both him and his eldest son to their limit to see how far their ursine genetics would take them. Would they have been able to suck everything down, or would they have floundered early? It was an experiment he was interested in undergoing.

Though it did make it a tad fortuitous that his youngest managed to overcome the usual hurdles and join him this year, as the three of them might be able to ingest everything put together. None of them had ceased consuming the entire time, so this shouldn't be any different.

The metabolism the pack of bruins possessed had been thoroughly trained to the point that it practically digested anything deposited into their roaring bellies on the spot, instantly turning it into overflowing fat that they'd later use for fuel in their sleep. Their minds grew hazy as time neared closer to the beginning of hibernation as all bears' did. Barely cognizant of their surroundings, they simply let their bodies swell however large they could, with enough time having passed that their grossly corpulent forms all squished against one another to the point that nothing could pry them apart anymore.

That was exactly what the three of them wanted even if not presently aware of it, all in the name of hibernation.

***

The passage of time continued to march onward as the three bears slumbered, not a single thing able to rouse them from their deep sleep. Days turned into weeks, bleeding into months that they put to good use, their impossible gains sustaining their hibernation. The oldest two of the three had done this plenty of times before, knowing exactly what they'd see when they woke up, but Bryan wouldn't have the foggiest idea of what to expect. All he knew was that he'd burn away everything he frantically piled onto his body over the course of a few months.

Not a single calendar or window adorned any of the walls, but that didn't matter when their internal clocks knew exactly when to wake them up. Springtime was finally upon them.

Bryan felt like a convoy of fully-loaded eighteen-wheelers had run him over before being thrown in the middle of the busiest highway in the country. Every part of his body seemed like it'd been put under a spell, his form feeling so heavy, as if being weighed down by the unyielding pressure that the bottom of the ocean provided. He'd never had such a deep sleep in his life, but he'd be lying out his ass if he said he didn't feel refreshed.

Groggily, he did his best to open his eyes, though the artificial light - programmed to be as comfortable as possible for the waking bears - made the task all that more difficult after not being used to it for an entire season. He groaned from the sensation of his body becoming more aware of itself again, the utterance rumbling in his throat. Man, even that felt off!

He could hear the other two come to as well. That got him moving a bit more as he tried, and failed, to gain any semblance of balance after sleeping on his back for so long. Success came eventually, however, and he managed to roll himself over, most of his body relaying the physical manifestation of television static back to his brain.

Clumsily he pushed himself to his hands and knees, unsure if the sensation of a massive amount of weight on his frame would dissipate at some point. Hibernation meant all the fat was gone, right?

Eh, he was just tired, that's all. Blearily he managed to get his eyes open a little bit, tiny pinpricks of light able to be seen as he stumbled to his feet. All he could make out were indistinct shapes that he didn't recognize. With the wall as support he could finally--

Bryan froze in his tracks. Not only did things innately feel wrong to him, but they physically did as well. His hand brushed past something his brain didn't recognize, only to feel it as being a part of him. It completely messed with how he mentally registered his body.

His hands immediately rushed to his eyes to get the sleep out and help see what was going on; it didn't even take much more effort than that for more things to feel off. Blinking his vision back into focus helped him gain more self-awareness, his anxiety rising as the numbness wore off in full. It was at that moment that he understood why things didn't seem right.

He was massive, which was true of him before hibernation as well, but now for an entirely different reason - he looked like a bodybuilder's wet dream. The height he gained from before had remained - which made complete sense to him - but instead of the plush fat he'd grown used to over the course of months, all he had now was impossibly thick muscle that bulged out no matter what action he took.

And then it hit him - this was how he was able to carry all that weight before!

But holy hell, did he not expect to see himself with the same body shape as his dad and brother. His chest was the obvious first thing to notice upon fully opening his eyes as it obscured a good portion of his view, the swollen pecs rising and falling with each laboured breath he drew. It felt unreal. A touch from both hands indicated that it was all real, but further investigation revealed that neither one could hold very much of those chest boulders.

"Oh damn, he's awake already." Stumbling to his feet, Viktor greeted his younger brother with a warm smile, though his expression instead changed to that of awe when he actually got a good look at the other bruin. "Holy shit, you're a fucking tank, dude!"

"Wait, what?" Bryan wasn't used to praise of that kind, but a quick comparison between him and the other bear showed that he actually now outsized his brother by a little bit. His eyes were wide as he perused the contrast between them, noting how they both appeared incredibly similar at first, but the measurements across his body seemed to fill out just that much more.

"Yeah, dude, you're totally swole as hell!" Viktor's laugh boomed through the room as he grabbed his brother by the shoulder, which even his large hand couldn't cover much of.

Bryan couldn't believe he now stood taller than his older brother; that'd be something he'd have to get used to now. "Uh, yeah, totally."

"Goddamn, Bry, apparently you were a bottomless pit!" Malcolm had been busy checking the stats the program recorded while it ran, a proud smile stretching from one ear to the next. "We finished the tanks faster than I expected, but you cleaned out nearly half of them yourself."

Hearing the data read out to him had Bryan in absolute disbelief, stunned at the astronomical progress he made during his first hibernation ever. The other two had been doing it for years at that point and somehow couldn't keep up with him. Maybe his body was making up for lost time? He'd likely never know.

But regardless of how it was possible, the results spoke for themselves. No part of him could ever be called 'small' anymore. Pecs that entered a room before his did weighed heavy on his chest, but the strength latent throughout him made them seem almost weightless despite each of them being heavier than what a bodybuilder was. They rolled into abs seemingly cut from marble by an expert sculptor, carved into cinder blocks thicker than what were normally used for construction.

Arms that bulged wider than tractor tires rested away from his body at an angle thanks to the sheer amount of bulk packed onto them. They appeared like they could lift anything, potentially putting cargo cranes to shame, though probably able to hoist the cranes themselves as well. Wine-bottle thick veins snaked along the split peaks of his biceps as he gave them an experimental flex, noting how the diameter of his arms alone were too wide for conventional doorways. Returning to his normal life might be a bit trickier than he realized it would be.

His back had grown mountainous, the peaks of his grotesquely massive musculature far higher than the spaces between them, giving him a looming visage that would tower over someone that much more. The sight was compounded by the fact that his traps actually rose higher than his head, meaning his ears were no longer the tallest point on his body. Not to mention his winglike lats flared out wide on his frame; he'd practically be able to park a car across them now.

Below the belt was a little tricky to examine with his eyes alone, but his hands more than made up for it, sending him reeling when he discovered the immensity that were his quads. While they weren't the thickest or widest muscles on his body anymore, that didn't stop them from utterly dominating the space around his legs, still needing him to adjust his posture in spite of his form having creaked broader across than two people to accommodate all his newly added beef. "Holy shit, I've got thighs for days!"

"Well, you know what they say - every day is leg day when you're fat," Viktor chimed in with a grin.

Bryan's hands continued on their journey of exploration, but the things they found made his jaw drop. His ass felt absolutely unrecognizable now, each dimpled cheek requiring a chair of their own were he wanting to sit down on one, though the act remaining an impossibility given that his rear end could crush a tank now without trying.

That brought him to his leviathan schlong, and, while he thought it was certainly impressive while he bulked up before, his cock now left that one in the dust in every metric imaginable. His throbbing tool slithered up his shredded torso, girthier than a decorative concrete pillar from antiquity and squeezing its way between his inconceivable chest boulders. Of course, they were nothing with a set of balls to back them up, ones fattened tremendously from his instincts kicking in and giving him a body to breed with.

Several solid moments of self-inspection had him leaking like a broken faucet. His face beat bright-red as he came to terms with his arousal, his orbs aching to drain everything roiling inside them. "Um, I don't suppose you can go and bring those suction tubes out again, can you?"

Malcolm dismissed his son's concern with a wave of his hand. "Ah, there's no need, we're awake now. Why don't you go ahead and ram that thing in my ass instead."

Closer than anyone else alive to reaching the one-ton mark of densely-packed muscle mass, Bryan stood tall as the living embodiment of virile ursine masculinity, a specimen the likes of which no man would ever physically match. He was a veritable colossus of legend... yet no one would be aware of that if they only knew of his personality on its own. "Wait, you..." He gulped, his nostrils flaring out trepidation. "You want me to do what?"

"Dude, you gotta try it. It's totally awesome!" Viktor sent his brother closer to their father with a mighty shove.

"You guys are really insistent about this." The situation had Bryan nervously chuckle, ending up in front of his father, also stiffened to full mast. Even with all the decades of doing hibernation that he didn't have, somehow he managed to even outgrow the elder bruin. The shift in size dynamics had him even more flustered than earlier. "Okay, so, I've had sex before, but never like this. I have no idea what I'm doing here."

"Just do what feels natural! Your instincts have guided you this far, right? They'll tell you what to do." As if emulating his point, Malcolm reached forward to the larger bear's dick and gave it a firm rub, feeling the flowing preseed coating his fingers.

Bryan almost couldn't handle the intense stimulation pummeling his system from just a simple caress of his tumescent rod. His father might be used to how sensitive a body of this size might be, but he was far from it.

Malcolm noticed the younger bear's twisting expression right away and stopped, offering a light-hearted chuckle. "Ah, my bad. Don't want you blowing already." Twirling around on the balls of his heels, he placed his hands against the wall as he presented his ass to his son, tuft of a tail resting atop his engorged ass cheeks. "Hey Vik, you getting in on this?"

"Nah, go ahead. I'm good with watching!" With excitement pounding through his veins, Viktor had gone ahead and started pumping his cock as he watched the other two get in position. The first orgasm post-hibernation was always his favourite.

Bryan hesitated slightly as he tried to navigate his father's swollen form in a body completely alien to him. Every touch of the other man's bloated physique had his brain craving more, wanting to feel more of the ursine's godly glutes. Parting those cheeks was actually easier than he figured it would be as his strength was enough to move them in spite of them tensing out of reflex, which gained him access to his old man's tailhole.

It was at that point where he really felt out of his element, not having any of the things he normally had around for sex. Lube was nowhere to be found, but he realized he produced a steady supply of it right from the tip of his cock. He slathered it all over his hand, painting it in the translucent fluid, before tentatively plunging a finger into the awaiting pucker.

The immediate acceptance caught him off-guard, so he upped it to two, then three, leading to his entire hand being welcomed by his father's asshole with little trouble. On one hand it made his job a lot easier, but on the other hand - holy shit, was that just normal for guys of their impossible size?

His raging arousal not wanting to waste another second, he lined the head of his dick up with the winking hole before letting it sink into the cozy anal cavity, a loud moan involuntarily escaping his mouth as a result. While likely the biggest pillar the world would know, it somehow drilled past his dad's delicate ring of muscle without trying. He couldn't imagine the amount of work needed to make that happen!

The feeling of having his insides be stuffed with a thick log of bruin fuckmeat after so many months had Malcolm's whole body tensing in a passionate frenzy of arousal, his hypermuscled physique nearly doubling in size at full flexion. It was like an itch deep inside him got scratched, frustrations built up over however long melting away as the sensation washed waves of pleasure over him. His libido, however, went in the complete opposite direction and spiked.

While the other two had barely started, Viktor was fully invested in pleasuring himself by then, one hand gliding along his telephone-pole shaft while the other one tweaked one of his fat nipples. His thick bottom lip was bitten from the euphoric bliss guiding his action. He snorted as he continued stroking his prick, practically fucking his hand. Being huge felt way too damn good.

Having the guts of another man of his calibre working over his gigantic obelisk had Bryan panting up a storm, his breathing laboured far earlier than he thought it would happen. The thought of blowing his load without doing anything felt embarrassing to him so he forced himself to build up a pace, slowly beginning the process of bucking in and out of his father. Getting balls deep in a guy always felt incredible, but doing it with a monolithic spire of myth and legend was in a whole other ballpark of unreal.

Malcolm shuddered as he felt his insides start getting scrambled by his son, feeling from the thrusting that his boy was losing any apprehension the situation bestowed. That was what he'd aimed for. Now he knew he could enjoy the ride, pushing his ass back to aid in the act while his own pole leaked rivulets of cum along his turgid length. He'd waited for this moment for a long time.

Bryan continually pushed his schlong into his father, flattening the other bruin's prostate like a button hooked up to the pleasure centre of the brain. He jackhammered the elder ursine's hungry tailhole like he'd done it a thousand times in the past. Instincts drove his every move, taking in every physical input available to fuel his libido and making him as good at the act as possible.

The feeling of his colossal testosterone factories slamming into his dad's only added to the experience, pleasure ripping through both of them. The more they worked together the hornier they got, lost in the sea of ecstasy that clouded their minds. As awkward as it might be, he didn't know if he'd last that much longer.

Viktor was off in his own little world as he worked his magnum dong the way he'd want a lover to. His breathing quickened as he neared the point of climax, his balls slapping against the ground as they audibly churned with spunk. He sucked in air through gritted teeth as he desperately wanted to get off. More and more he bobbed his hand along the veiny cockflesh, the feeling reaching a boiling point soon.

One hand of Malcolm's still kept him supported against the wall while the other hand shot to his crotch rocket, feeling the diamond-hard schlong throb wildly in his hand. Every flex of his pelvis tensed it as the veins pulsed along the length. He could feel his son's inexperience, but the size of the cock in his ass more than made up for it. The overwhelming sensation of having his inner walls gripping a rod of that magnitude had him groaning for release, feeling it coming soon. Only a few more thrusts to go.

Bryan felt like a hot mess of emotions as his body struggled to make sense of everything being told to it. His fucking remained regular despite his faltering composure, but it was quickly fading fast as orgasm neared. The point of no return rapidly approached with no way of slowing down. He soon made it to the edge of climax before one last pump of his hips drove him right over, heralding the start of his cum tanks draining with a strained roar that he had no practice making. Within seconds his cumpipe blasted out thick, virile bearbatter, inundating his dad and painting those insides a pearlescent white. His grip on the other ursine's lats tightened as a result.

The feeling of his guts being flooded triggered a reaction in Malcolm, whose own cock let loose and fired off bucketloads of creamy jizz that painted the wall in front of him. He moaned aloud from the immense pleasure throttling his system, threatening to buckle his limbs. But still he stood, ass cheeks flush with his son's crotch, his tailhole sealed around the thickest cock in the world. There wasn't any way he could be happier right now if he tried.

Hearing the sounds of the other two titans let go caused Viktor to do the same, his eyes screwed shut as his balls pulled up to his pelvis, blasting his dam wide open and shooting spunk all over the ground in front of him. The only thing he felt was unadulterated bliss, thoroughly reveling in the euphoria that came with all that size. His nerves sent shockwaves of delight as he emptied his balls of everything they'd produced up to that point. Getting the chance to take part in this with his family felt like heaven to him.

The trio of behemothian bruins continued for what seemed like eternities as time slowed to a crawl. Their never-ending streams of cum were merely illusions, though it took a little while for the effect to wear off. They each tapered their streams off one after another, the pool of jizz on the floor a few inches thick as the drain in the centre of the room struggled to keep up with all the output. None of them had seen that before.

Bryan felt ready to pass out after what he considered the best orgasm of his life, though his body retained enough vitality to keep him awake. Through wheezing breaths he wondered aloud if that was a common occurrence for the other two bears, to which they laughed and stated that their bodies had cravings and it'd be foolish to try and fight them.

He couldn't argue with that; they all had instincts for a reason.
