My footsteps echoed faintly around the surprisingly large chamber as I was led deeper into the complex. The only other sounds were a kind of chemical bubbling and gurgling from off to one side, and the far distant drone of more construction work ongoing, my guide was silent after our initial greeting. The silence was preferable to the loud creaking and shuddering from the elevator as it carried us up and up into what I remembered with concern was a very hastily constructed building, but somehow we made it to the top floor without incident. Top floor, though it was, the roof loomed high overhead, and the walk through the otherwise empty seeming structure lasted a good few minutes more.
"This is a massive building." I said, trying to break the silence.
"It has to be, in the circumstances."
Attempt at conversation trailed off, and I just followed until I was shown to an open metal platform attached to a large mechanical crane. My guide gestured me aboard, and turned to the controls.
"Are you not coming too?"
"Management prefers us not to go in there too often, just in case."
The platform lifted me up into the air and along, through an opening into the next room, where my latest interview subject was sitting. I had seen the news reports, of course, read over the numbers in preparation for this assignment, but being there in person, seeing the site for real, had me stunned for a moment. As the platform stopped, Adrian set his tablet down on the surface surrounding him and turned his attention to this new visitor, I summoned the best professionalism I could and kept my focus on the interview, rather than the view behind and below me.
"So, Adrian, thank you so much for agreeing to this discussion. It's been a year since your... unusual case was first examined. I think, for now why don't you tell us all how it started for you."
I set up my recording equipment and watched him think back to his former life.

~~~~~

Adrian stood admiring the view in the mirror, dropping the pose a bit to quickly brush his huge, floppy ear back past his mountainous back and shoulder before flexing again, straining his biceps up and up, twice as big as his head, and with a grunt of effort pushing that impressive peak up even higher. He would need to get the measuring tape out later, but the improvement was clear. He still had a couple of weeks work to be on top form for the super-tier bodybuilding qualifiers, but this time, he was sure he was ready. Relaxing his arms, he turned and twisted, admiring the rest of his huge figure, a sight he didn't often get to see, down past the thick mass of his own pecs, looking over his deeply chiselled abs and thick mass of his thighs as they pushed his shorts all the way up. The big bunny's eyes lingered on those shorts a while longer. There was something about the way the extra tight fabric pulled tight around his rear and his package, showing off every detail. Especially as that package swelled slowly firmer with every moment of his examination of himself. Adrian quickly checked the time, he still had a while before he needed to set off for work. He tugged his shorts down and let his full mast cock spring free, the shaft squeezing out from between his massive thighs. There were many benefits to being as big as he had built himself up to be, but enjoying this view in private moments was definitely one of them.
Eagerly, he grasped his cock in one paw, slowly stroking up and down, the other exploring over his well muscled body, teasing and stroking his short fur. In moments he was squirming and panting eagerly. Playing with his growing body always got him excited, but today it was more intense than usual. Before long, he was moaning loudly, free paw braced against the ceiling just over his ten foot high frame, as his thick load burst out and clear across the room. As he came down from such an intense orgasm, catching his breath, the impressively muscular rabbit realised it was lucky he had finished so fast, he had misjudged the time and needed to hurry off right away. Squeezing himself into his custom made uniform, he quickly checked his pockets for essentials and rushed out the door.

The tips a massive bodybuilder in an outfit that stretched tight over every one of his huge muscles got while waiting tables almost made up for his need to still work a regular job, almost. Soon, though, he would be getting that prize money and the sponsorship deals, maybe even a few modelling contracts... Adrian found himself fantasising about posing for advertising in tiny revealing outfits even more than usual through that evening's shift, until he struggled to concentrate on his work as it got busier. For some reason, though, every one of his fantasies had a huge raging boner straining in those skimpy outfits, however much he tried to imagine otherwise. As the evening went on, it became harder to keep his thoughts away from the rock hard cock he had in real life. He hoped it wasn't too obvious to the customers, who would be down closer to that height, some way out of view behind his pecs. Eventually, the strain became too much and he had to ask to take his break earlier than usual to slip off somewhere private and try to calm down. Tugging his persistently thick, hard, throbbing shaft out, he started trying to calm it the only way he knew how. Catching sight of himself in the bathroom mirror, Adrian lumbered closer to get a better look. The room was not really designed for someone his size, his head brushed the ceiling in most parts of the restaurant, but he managed to squeeze in and peer at his body. Even so soon after last time, his insistently horny cock seemed to be straining bigger and longer than usual. Maybe it was just the way his body blocked the light, but he was sure the gently oozing head of his shaft was an inch or more further past his paw than usual. The thought of having a big, impressive package between his legs to go with the rest of his huge figure had him erupting over the mirror in seconds, again and again, until it was dripping with cum.
Cleaning up as best he could with head spinning from two powerful orgasms in quick succession, the huge bunny tried to get his mind back on work and away from his arousal, but it didn't last long. By the time he was heading home, he was straining to keep his paws away from his pants, feeling excessively pent up, and back home he was dozing off to sleep just seconds after splattering his pecs with another thick load of cum.

The next morning, Adrian headed downstairs to his personal gym, trying desperately to burn off all his energy working out until he could barely stand, legs shaking, heart pounding. This time, he remembered to fetch the tape measure, but today, however much he strained and squeezed and pushed his huge biceps and triceps, he couldn't quite get it to edge past the 100 mark at the end. Yesterday he had been so sure he was ready, but today not so much. If anything, it almost seemed like he had lost a half inch or so off his arms. Trials for his first proper competition were too close for him to be slipping like that, he needed to work harder.
After a rest to catch his breath, get plenty of protein rich food, take a bath, splatter the bathroom with cum, he headed back to the gym to keep pushing himself harder. It did not go well. His muscles were struggling and faltering just a bit on weights he should have been able to manage, on numbers of reps he had been able to complete before. Not expecting much, he grabbed the tape measure and tried again. The sweat soaked, panting bunny tried to brush that 98 inch mark off as just being too worn out to flex all the way, he had pushed himself unusually hard all day, but somehow he wasn't entirely convinced. Measuring tape still in his paw, Adrian had a thought and lay back on the bench until he could pull his shorts down. As tired and drained as the rest of his body was, somehow still one part of him was eager and full of energy. He checked and checked again, just in case. But no, a full twelve inches of cock towered over his abs, straining upwards almost high enough for him to see past his chest again. The thick, veiny shaft begged for his attention, and his balls, feeling bigger and heavier themselves too, groaned in pent up frustration when his tired arms couldn't keep up with their demands.

A week later, Adrian was in the waiting room of the doctor's clinic. His arms were multiple inches smaller around than they had been at his best.  His head no longer brushed the ceilings at work. His oversized package was threatening to bulge out of his shorts in front of everyone, even though somehow, for once, he wasn't rock hard and constantly aroused. Something was definitely wrong, and he needed to find out what. By now he was sure he couldn't regain those lost inches in time for next week's contest, but surely he could gain them back, and more, by next year's. Just as soon as he found out how to stop himself shrinking.
"I'm afraid your level of muscle growth and fitness training isn't something that's covered in a general medical course, you'd be better off talking with a specialist. Perhaps a coach or gym trainer, they could talk you through things like body size plateaus and muscle building cycles better than I can."
"But I'm also shorter than I was before, and..." Adrian hesitated, he wasn't sure if it was the prospect of talking about his massive cock to a complete stranger, or the idea that he was complaining about assets big enough to make any man jealous and still growing. Perhaps now was not the time.
"Well, we can certainly run a couple of tests, take a few blood samples and get your hormone levels and glandular physiology checked out. It'll be a week or two before we can get any clear results, but I need you to stay calm, it's likely not anything major. Perhaps your body just needs a bit of a rest from the strain you've put it through competing at your level. And before you say anything, I mean rest now, not 'after just this one last thing', I know how that ends up."
"You can't give me some ideas of what it might be, maybe something I might be doing wrong in training or a virus I picked up..?"
"I've not heard of any virus that could make a person a couple inches shorter overnight, no. Like I say, you might need to speak to a bodybuilding coach, maybe you exercised wrong and your posture has been a bit slouched since. We can check that now, if you want, while we run our other tests."

By the time the contest day arrived, Adrian had bigger problems to worry about than just making it to that particular qualifier round. He stood in the audience to watch the show, to see the huge, impressive figures of the people that should have been, and hopefully one day again would be his rivals. They were all so much bigger and stronger than he had been even at his peak, the big bunny realised he would have barely scraped into the contest, never mind had a chance of winning, but there was always next year... He would have many months of training ahead to catch up and then surpass all of these guys.
Just watching the show, seeing all these impossibly huge muscles on display, these incredibly well built and maintained bodies in tiny, revealing outfits, giant flexing biceps and pecs everywhere had him squirming in his seat. His libido had been in overdrive for a while, and those grapefruit sized nuts resting in his underwear didn't help matters, begging to be emptied over and over, and yet only ever seeming to swell bigger and heavier and more full each time. Luckily, being nearly a foot shorter and plenty smaller around the thighs in just a few days meant his clothes were big and loose, the folds of the fabric doing something to hide the massive, powerful shaft straining against them, the almost two feet of rock hard, veiny, throbbing cock, gently oozing in its perpetual excitement.
With some effort, he managed to hold back an eruption, and keep his moans to a minimum, but the overly horny bunny had to excuse himself and shuffle awkwardly out of the building only half way through the show, trying his best not to make his arousal too obvious. In a secluded corridor, away from the crowds and bodybuilders and excitement, Adrian struggled to rearrange himself in his clothes, but that boner, thick enough that even his massive paws couldn't wrap around the whole girth, resisted every effort to shove it into a more convenient position. Hearing a noise nearby, Adrian pulled his paws away and tried to act natural as a huge wolf strode down towards him, towering above Adrian's own nine foot high frame, and with shoulders and triceps bulging until he filled the whole space.
"Hey there, enjoying the show?" the huge canine boomed, squeezing past way too close to the squirming rabbit in a corridor not built for people of their size. A powerful pleasurable shiver ran through his body as he came so close to such a powerful body.
"Certainly looks like it." the wolf added with a glance down at the now way too obvious tent in Adrian's shorts. "If you want to come around to mine afterwards, maybe I can give you a private performance?"
The wolf squeezed past, making sure to press far more of his almost naked body against the squirming, moaning rabbit than necessary. Adrian didn't say anything in response, every effort he could spare was going towards struggling against the impending explosion in his pants. A struggle that proved futile, as within moments he was blasting out thick loads of cum over and over. It took some time before he caught his breath and cleared his head of enough of the lovely dazed feeling after such an orgasm to think about finding some way out of the arena.

When someone well over eight feet tall and almost as broad across their impressive, clearly defined and bulging muscles bursts into a hospital reception area shouting about needing help to stop themselves shrinking, the first thought of the staff is not to take the incident entirely seriously.
"Please stay calm, we can arrange for a doctor to see you as soon as possible. Take a seat and I'll let you know when one is available."
The receptionist directed Adrian towards the waiting area and made some notes on her computer about this patient, some kind of 'shortstack syndrome' where they seemed to believe they were much smaller than they clearly were? Hopefully the doctor could calm them down and see them properly treated.
It was some time later that a head peered around the doorway and called him over, showing him down a short corridor to their little office. Adrian sat awkwardly in a chair that was too small for him even at his new size, looked down awkwardly, nervous to talk about himself now that the time had come. He dug around through his jacket pocket and pulled out a couple of older photos of himself, showing off his full former size.
It didn't take much more convincing for Dr Ivania to start taking him more seriously, she got him to stand up and took some measurements of his current height and weight, and a quick blood sample for testing. While they waited, they talked about his condition, how long it had been going on, whether he had made any changes to his routine, started taking any new supplements. Throughout, though, it was clear that the doctor's attention was being pulled away. Adrian wriggled about in the seat, trying to pull his jacket into a better position, trying to keep his own attention on the straight forward facts, but throughout their short conversation, he couldn't keep his package from swelling slowly thicker and harder in his pants. Even before he was fully hard, his shaft stood a couple of feet long, straining the tight fabric of his clothes. He could feel it creak and groan as his massive nuts gurgled full of too much cum, eager for release.
"Have there been any... anything else you've noticed? Any other symptoms or changes to..." the doctor trailed off, trying to keep her eyes off that impressive package.
Adrian blushed brightly and tried to think what to say. Just at that moment, a powerful throb through his veiny cock pushed it to full size and maximum hardness, ripping through the seams of what had been loose, baggy clothes. As he struggled to find some way of hiding his increasing arousal, he stammered through a few attempts at words. The doctor, face also flushed bright pink, pointedly looked the other way.
"If it's easier, you can take a moment to write some things down for me to read instead. And you're definitely sure you've not been taking anything new? It's just that your hormones are showing in some unusual levels, and not at all the mix we would expect. Which would explain your chest..."
"My chest? What about it?" Adrian rose from the chair and stepped over to a mirror, lifting his top and placing one huge paw against his powerful pecs, the touch sending another shudder of pleasure through his overly engorged shaft. "My pecs are about the only part of me that isn't shrinking alarmingly fast, they're near enough as big as they were at my peak."
"I'm afraid that's not quite the case." stepping up behind him, putting her own much smaller paws against Adrian's chest, pressing and squeezing his immense bulk "Ah, just as I thought, you're showing some significant fatty build-up as well here, just about what would be expected for someone with such elevated levels of progesterone and other female hormones."
"W-wait,.. you mean I'm..." Adrian stumbled over a few words, one paw braced against the wall, fingertips digging into the plaster as his raging hard boner oozed a growing trail of pre-cum. It didn't take much more of the doctor's examination of his plump, full chest and thick, hard nipples before the first cum eruption blasted outwards against the mirror.

"We can set you up with something to mitigate the effects of your hormonal imbalance, and also slow down your libido a bit, it should at least reduce the rate of changes you're undergoing, but for now that's the best we can manage. Our top priority will need to be investigating what's causing this effect to start with, and how to stop it completely, which is beyond the facilities we have available here. However, I can make a few calls, and see what we can arrange. For now, just take each of these pills once a day, and that should slow your muscle loss and other ongoing body changes, and also prevent your impressive... uhh, that is... elevated levels of..." Dr Ivania had gone through the whole spiel at high speed, trying to race against her own growing embarrassment at what they had done just a short time before. The potent smell of Adrian's cum still hung in the air throughout the office. She handed him the bottles and ushered him away, taking a while to herself before she was ready to see another patient.

Adrian shuffled about, tugging on his work clothes, trying to make them fit a bit better. Now that he could no longer fill out the custom uniform they had gotten for his ten foot tall, muscle mountain form before, he needed to get by with what was available, and for someone that was still a good head and shoulders taller than anyone else on staff, still impressively buff and bulked up, even if not quite to super-tier bodybuilding levels, and also for someone with far too much bulk in his overflowing underwear and a plump, round pair of melons bulging out of his top, nothing came close to fitting well or hiding any of the considerable changes his body was undergoing day by day. His increasingly obvious boobs now got almost as many concerned and disapproving looks as the impossibly huge bulge filling his pants. Customers made a point of looking the other way, even when he tried his best to hide his figure, to keep his bulge out of sight behind the furniture, and his once impressive and bountiful tips had almost entirely dried up.
"Is there nothing more you can do to..." his manager gestured towards, well, all of him. "I've just had yet another complaint from a regular customer, and however much I try to explain that it's a medical issue outside of your control and so on, well... they're going elsewhere now, before long the only customers we'll have are the ones that come to stare at your body and, well, you know... This isn't that kind of establishment."
"I'm doing everything I can, my doctor is working hard on something to help, I'm taking all the drugs they give me, I've started taking them more often than they say and it still doesn't seem to be doing anything. I'm out of the bodybuilding contest, perhaps permanently, none of my clothes fit any more, there's nothing more I could do, and if there was, believe me, I'd be doing it, whatever it takes... I just hope it's not contagious."
The manager raised his paws in shock and took a couple of steps back, looking around to see if anyone else had heard their conversation. Two days later, the paperwork was in place for Adrian to be placed on a long term leave from the role, paperwork that was handed to him from as far away as possible.
"I'm sorry, I just can't risk... as soon as they're sure you're not going to infect everyone else with the same thing, then we'll see about... well, we'll see what happens. I hope things work out better for you soon."

"You've got to do something, none of this treatment is helping." Adrian demanded, getting increasingly frustrated at this new doctor that had been assigned to his case.
"We're doing what we can, and I can assure you..."
"What you can isn't enough, is there nobody else that knows better? Where are the experts?"
"I can assure you, the treatment is working, your tests are coming back with reduced symptomatic effects, hormonal levels are closer to expected rates, every sign shows that the pills are having a positive impact on the condition."
Adrian leapt out of the chair and strode across the room until he was right in the doctor's face, or at least the plump, round melons bulging out of his top were. He looked down at the badger through his ample cleavage.
"You call this positive? A reduced impact? I'm still... my body is still changing around me, all the effects are still carrying on as though you've done nothing. I'm multiple feet shorter than I was just a month or so ago. Years of weight training has just... fallen away from my muscles. My butt doesn't fit inside regular underwear any more. Why is my butt huge? None of this makes any sense, and after all these appointments and all these drugs, I'm still looking like this."
"You're right, none of this makes any sense. We have no idea where this condition came from, what caused it, we're not sure how to stop it. But the treatment is having some effect, we are slowing the changes. I can see about increasing your dose again, but at the moment, we can't do anything to completely stop or reverse these effects. I promise you, as soon as we have an idea, you'll know."
Adrian's top creaked ominously as every deep breath during his angry outburst strained the already tight fabric. The impressively well endowed bunny tried to calm himself down, backed away a step or two.
"But, there is some good news, I've been able to get into contact with someone that can get you a supply of specialist clothing to handle your increased size, they have a good track record of providing ultra and hyper sized outfits for all kinds..."
"Wait, hang on, how... how big am I going to get..?"
"We don't know. But as you say, your condition is continuing to develop, we have to assume your proportions will change in the same manner for... well, our hyper growth analysts have some ideas on what may be the maximum limits, presumably you'll fall somewhere between that and your current figure."
"Until you can find some way to reverse the effects."
"Yes, yes... of course. But we need to prepare for anything, you understand."

Adrian sprawled on the bed, still feeling strange at how small he was on furniture that had once been bought specially for his impressive height. Now, with hefty watermelon boobs, a cock that brushed the floor when soft, and a butt that kept trying to get caught in narrow doorways, moving around was more hassle than in was worth, so with nothing better to do with the day, the bunny sprawled over a mattress twice his own size.
At the moment, though, his cock shaft was anything but soft and dragging on the floor. He was looking through files relating to what his doctor had said about how big people could grow. Looking at pictures of medical patients with boobs wider than their outstretched arms, too heavy to lift without specialist equipment, people posing alongside cock shafts double their own height, swimming pools full of cum, one person whose package was so big, his toes barely reached the ground either side of it, all of it was a shocking insight into what might happen to him in the future. It should not have been exciting and arousing, yet his massive, towering boner, throbbing with wrist thick veins all along, had other ideas. Adrian could see the head of his massive cock bobbing up and down in time to his pulsing veins as it loomed over his huge breasts, as much as he squirmed and moaned, he strained to keep his mind off it, he wasn't going to be jerking off to visions of his own unwanted future, however much his oversized and overly aroused parts insisted.
The more he looked through pictures and descriptions, of custom made outfits and homes and equipment just for lifting and moving such huge assets and draining them over excess cum and milk production, the harder it became to keep his mind and paws off that raging hard cock, until he was gripping his phone tightly, every effort on not reaching past his plump, firm boobs and grabbing that towering obelisk in both paws. As he wriggled and moaned and struggled to resist, cum oozed and drooled thickly from the tip, splattering over his bare chest, warm and soft, and from there it was only a matter of time. Even without his paws to help, it wasn't long before he was erupting powerful bursts of cum against the wall behind him, one shot after another slamming out, splashing and splattering over the rest of him, soaking into the bed sheets, dripping down into the carpet.
After the biggest and most amazing orgasm he had ever felt, Adrian flopped weakly against his cum soaked bed, his giant boobs rising and falling above him with each deep breath. It was some time before he got his thoughts together enough to awkwardly roll his expanded assets off the bed, scramble to his feet with his unfamiliar new size and weakened muscles, and survey the mess he had to somehow clean up. At least it wasn't swimming pool filling. Not yet...

The shrinking bunny reached up instinctively to brush one of his massive ears away from his face, as he so often had before. This time, his paw batted against the giant form of his massive breast, something he was still occasionally forgetting about, even as he struggled to carry the weight of them around. He pushed the ear back into place, letting it drape over his huge, rounded rear, threatening to reach the ground behind him if he continued losing height at this rate. Insistent on trying to live some kind of normal life, he had forgone his recent habit of ordering groceries online, wrapped himself up in the best he could manage for clothes that fit, and gone to the shop in person.
It was not going well. Every step was a struggle as his muscles weakened and his other assets swelled bigger and heavier, Adrian could feel his legs shaking as he carried his giant butt and boobs from one aisle to the next. At least he didn't need to worry as much about lifting that massive bulge, since his balls were dragging on the floor now, instead it was just the challenge of walking one step at a time with that bulk right in the way.
And, of course, the challenge of reaching the high shelves. At barely five feet in height, the short, broad bunny was up on tip toes trying to grab things he would have struggled to bend down far enough for a few weeks ago. Even the lower shelves were more often than not out of his reach, as he strained past his broad, heavy bulk, overstuffed underwear pressed up against the shelves and freezer cabinets, boobs getting right in the way of seeing anything below eye level, every movement a chance to knock things over, tumble displays, brush what he wanted onto the floor instead, where bending down to grab it was pretty much never going to happen. And best of all, people weren't helping him, any time he tried to approach someone to ask for help reaching a high item or picking up something he had dropped, they'd scurry away instead, or pointedly not look and act like they couldn't hear. Adrian spent far too much of the afternoon, wearing out all his patience and energy, on what he was increasingly sure was a futile gesture. All he had proven was that he couldn't shop by himself.

Adrian looked up at the otter standing at his door. That was the bit that bothered him the most now, he was shorter than other people, for the first time in many years, he had to look up to see people, and not just because a creaking tight and round pair of beachballs was bouncing about on his chest, threatening to fill even more of his view as they swelled day by day.
"Good morning... sir?" the otter stumbled over the word uncertainly with a glance at Adrian's oversized bust, before carrying on. "I've been sent by HRMD, the hyper research medical division, we have an opening for you at a group study environment."
Adrian peered past his own assets with increasing confusion.
"I believe your doctor spoke with you regarding this? You..." he flicked through some paperwork quickly "you were asking about being seen by experts in handling your medical condition, I have a referral to be examined by senior doctors of the medical division at their facility. This is a, let's see... they're proposing a week long study with potential for expansion... sorry, I mean extension."
"What would this study involve? Are they able to cure me, or..?" Adrian could feel himself slurring slightly over the words, perhaps it was just lack of habit, where he had kept to himself for some time, but speaking was becoming difficult, the few times he needed to.
"I can't say anything about the medical aspects, as to whether the treatment will be successful or, well, you understand, I'm not a doctor myself. But the study period would be a stay in a facility specially designed for people of your size, or larger, you'll fit in well there, if you'll, uhh... well, plenty of the best doctors in the business work there or visit, if anyone can find out what's causing your unusual changes, they can."
Adrian's expression, as much of it as was visible, had been getting more and more irritated at this otter's overly friendly and enthusiastic manner, but he had to admit, it was the best chance he had. He took the offered paperwork, skimmed through reading it and, with some difficulty, managed to sign the form.
"You know, it's not all bad, I'm sure some people would love to have a body like yours, if all else fails maybe..."
The otter blushed brightly and turned away.
"I shouldn't say things like that, I... Anyway, shall we get going? Or do you have anything you need to do instead?"
"I... uhh, right now? I should probably pack a few bits to take with me, but there's not much..."
"Don't worry, I've got all day for you."

Sitting in the back of the truck felt weird. Adrian had struggled to get his armchair width rear out through a door that had been previously adapted for his immense muscular figure, but sitting here, he felt small. There was loads of space, in between bits of medical equipment tucked out of the way, everything was sturdy and reinforced, and a range of mobility aids and seating options for people many times his size were folded up against the walls and floor. For a brief moment, Adrian felt comfortable, until he started thinking of what might happen if he grew to that size, or bigger. Just the thought of being that huge, barely mobile, helpless against his own body had the rabbit feeling rising panic, and also rising arousal. Struggling to keep his thoughts elsewhere, even if just to slow the swelling and rising of his vastly oversized cock, he grabbed his pill bottles and took a couple extra doses of the ones that were supposed to tame his hyperactive excessive libido. They at least seemed to be working, he was sure he would be in a state of near permanent orgasm without them. Not a thing to think about when he was trying to keep his half hard shaft from overflowing out of his uncomfortably tight pants.
Watching the view passing by outside instead, Adrian managed to make it to the facility without a four foot long raging boner springing up ahead of him, just about. At least, he was until this otter, Bradley apparently, got a little too close while helping him out of the truck. Feeling something tight pressing against him, the otter looked down in confusion just in time to watch the monumentally huge cock unfurling and rising up between them, pushing his entire body backwards with the force swelling it, until it was towering rock hard and eager before him.
"I, uhh... Sorry, I, well..." he stammered, staring blankly at the massive shaft, his own comparatively tiny package straining hard in his own clothes.
Bradley was able to carefully guide the still hard and horny bunny around a more discrete outside route and into the facility through a side door, leading up to a space where he could take care of his urgent needs.
"If you, uhh... need a hand, or..." the otter stammered, blushing and looking down at his feet.

Bradley slowly came back to his senses, the intense dazed feeling from his third? orgasm, he thought, gradually fading, he clambered back to his feet, entire bare body soaked with bunny cum. He couldn't see Adrian any more, the hyper endowed rabbit had slipped away while his mind was lost in a sea of overwhelming pleasure, but he could hear the tell-tale grunts of someone trying to stuff excessively large assets into clothes.
The otter showed the short, impressively well endowed bunny around the facility, seeing all the sights. They took it slowly, even with the building's extra wide doors and limited amount of stairs, for a barely five foot tall, slender figured guy carrying beachball boobs resting atop a package that almost dragged on the ground, that amount of walking was a strain. Adrian settled into his new apartment, with its open plan layout, massive mattress, waterproof flooring, huge doors, facilities and mobility aids set up for guys his size, or bigger.
Each day, doctors would come and perform a series of tests, getting him to jog on a treadmill, hooking him up to machines while he slept, making him refrain from masturbating as long as he could before his cock erupted by itself, something that took only a few hours. They took samples and analysed them in the lab, changed up his medication every couple of days.
And each day, Adrian would wake up, roll awkwardly out of bed in a heap of oversized bodyparts, check himself in the mirror to see how much shorter he was this time, how much bigger and heavier his breasts and rear had bloated, how much further ahead of him his cock shaft strained. And within a few days, he watched bit by bit as his lips plumped up thicker and rounder too. Every day, the effort to speak past them was an increasing struggle, but the bunny made a point of doing so as much as possible, to learn as best he could to deal with his new body. It was almost a week before the bunny gave in and accepted that he needed some kind of help getting around. With his head barely at chest height on the staff at the facility now, his toes strained to reach the floor either side of his constantly swelling, creaking tight and full balls, groaning with far more cum than even his massive cock could seem to pump out in multiple successive orgasms throughout the day.
A couple of wheeled carts under his assets helped him move around the wide open corridors of the lab buildings, making moving that considerable weight around much easier, a good thing too since his arms and legs, once supporting over a ton of powerful muscle bulk, were now stick thin, apart from where his vast butt flowed into plump round hips and thighs. After this, a camera setup helped him see past boobs that ballooned higher than his own yard and a bit of height, sticks helped him drag himself along, slowly but surely once his tiny feet permanently lost touch with the ground. Adrian insisted on remaining mobile as long as he could, even as every test and every new experimental treatment failed to stop the steady, ongoing changes to his body.

Eventually, the day came when he had to admit defeat and move in with the other immobilised hyper residents. Wheeled into the other part of the facility, Adrian could see through his cameras that he was by far the smallest of them, though that made sense, given how far the non-hyperised parts of his body had shrunk. Aside from his still massive ears, he measured a total of 26 inches from top to toe, as best the staff could reach his toes, pinned tight between his bloated butt and creaking full balls as they were now, his whole non-hyperised body barely as large now as one of his triceps alone had been not so long ago.
He settled into his new home, tiny body nestled tight and cosy between the towering arcs of his giant boobs ahead and giant butt behind, both rising far above head height, puffed up lips constantly in view past his nose, in between the chasm of his cleavage he could still see the tip of his almost constantly rock hard and throbbing cock, twenty feet ahead and still moving away. At least he had something soft and comfy to rest on, even if it was his own huge body. Food, medication, entertainment, contact with the outside world, everything was provided for him in that snug little space, as day by day the walls of his imprisoning figure rose higher on all sides. At least he wasn't shrinking any more, his tablet seemed more like a TV screen now that he was a fifth his former height, but it stayed that scale, even as his breasts rose inch by inch, foot by foot higher and wider ahead of him, even as his cock shaft disappeared further into the distance of that huge, open space, slowly raising the rest of him up and up where it rested on the floor between his other assets.
Gigantic tablet and phone aside, most of what Adrian did each day was squirm and moan and try to thrust against his own huge assets. His cock was pretty much constantly rock hard by now, massive veins pulsing all down its thirty feet of length, leaving the bunny endlessly, constantly horny, orgasming over and over without any relief from his need for more. The facility staff had very quickly set up pumps to drain his cum floods after the first powerful explosion came from his being left most of an hour of endlessly rising, helplessly overwhelming need while he was first being moved into the immobile hypers hanger. Now, orgasms came every few minutes, slowly but surely bigger and faster and closer together, and always never quite enough to relieve the endless arousal the bunny felt every moment of his confinement to his own bloated body.
Days merged into each other, every day his swelling cock girth lifted him another few inches closer to the roof, his boobs sprawled a little wider and heavier ahead and beside him, his butt bloated a bit plumper and higher behind him, his balls creaked a little more insistently with their cum filling, the mechanisms set up to safely induce orgasm and drain his cum floods away moved slowly further from him as his shaft lengthened bit by bit. The constant feeling of horniness, of needing to cum just a little more, never quite satisfied by the steady rhythm of those repeated orgasms was just part of the background of his life now, as was the knowledge that the same steady routine was the only thing keeping him from the extremes of arousal, potentially to the point of mind breaking delirium and unending orgasm that would come within minutes if he was left without any means of release.

So it was that one morning Adrian realised something was different. No longer just mildly unsatisfied, now waves of desperate need swept through him over and over, until he could barely concentrate on anything else, not even the view of his own body swelling at an alarming rate. The whole building seemed to shrink around him as his cock raced away, ripping apart the machinery set up to support it as it gained extra feet of length and girth in moments, before disappearing entirely from view behind his ballooning breasts. Adrian's boobs swelled so fast he could hear them stretching and straining as they rose inch by inch and then foot by foot upwards and outwards, the space between them and his butt shrinking as his body pressed in closer around him, the opening above his head tighter, higher, further away by the moment. Clinging tight to his own swelling assets, Adrian struggled to fight back against the incredibly exciting, arousing feeling washing through him over and over. Straining against his extreme need for more pleasure, more orgasm, more release of tons upon tons of pent up cum, the tiny bunny reached across the shrinking space around him for his pill bottles. Maybe if he downed the entire dose of whatever was meant to slow his growth and diminish his libido, it would stop whatever was happening to him now. Reaching out with his tiny, week arms, shuddering with waves of orgasmic pleasure as his rapidly growing cock begged for release, he managed to grab the bottle, open it, and watch as another intense wave of arousal swept through him with enough force that his eyes rolled back in his head, his grip failed, and the whole bottle and contents tumbled down the tight gap between his warehouse sized boobs and butt. As much as he struggled and wriggled, with only head and shoulders mobile between the tight press of his own growing figure, he couldn't reach even a single one of those pills.
Adrian could only watch helpless as his boobs squished and crushed his tablet between them, as the roof closed in on his swelling form, as sudden light and crashing sounds revealed that the far distant head of his cock had burst right through the massive hanger set up for some of the country's biggest hyper endowed residents. That was the last thing he saw before the growing need for release finally overwhelmed him and the cum explosion started.

"And that's the last thing you remember?"
"T-they tell me it was over a day before I was coherent enough to speak again. Still orgasming, of course, and still growing..." Adrian managed between soft moans and gasps. I was already struggling to understand his story past his fat pillowly lips, I would need to slowly translate the recording once it was done, but now it was clear his growing arousal was making speaking even more difficult. 
"Apparently by that time you were over a mile, from cock head to butt cheeks? At least that's what the statistics say, not that they can show what it really feels like to be that big."
"It's hard to describe... beyond the non stop orgasm, beyond the parts so big I can't see where they stop curving upwards in the far distance. That was all a thing from the start, a mile long cock might as well be endless for all the difference it makes, but... There's another feeling, deeper, stronger, more powerful than orgasm, the feeling of your own body growing, swelling, expanding around you. Nothing can compare to that, it overwhelms everything else, and doesn't stop. At least, not until I stop getting bigger, if I ever do..."
"Do you know how many miles..?"
Adrian shook his head "I prefer not to know. Not much I can do about it anyway."
"You know why I'm here today?"
"To interview me, that's all I've heard..."
"It's been a year, today, since you gained that first inch or so down there. They've told you other similar cases have come up around the country?"
"I remember it being mentioned, while I was at the facility, they were doing tests to compare... how are they..?"
"In a couple of weeks, one will have been shrinking and growing as long as you were on the day... well, on that day. We don't know if she'll have the same thing happen as you did, but... Six more cases, that we know of, still no certain cure, or even long term delay to the effects."
"I hope they can find something, e-even if not for me... Even if I knew how to help, there's not much I can do, I-I can't even move now..."
Adrian's words faltered to a stop as his struggle against his unending orgasmic floods of pleasure and desire overwhelmed him, it would be some time before he would be able to hold a conversation again, and I needed to move out of the way of the workers that were adjusting the facility as he continued to grow inside and around it. I took one last look at the tiny bunny head and shoulders squeezed tight between mountains of fluffy mass I only knew was his breasts and backside from medical reports and aerial photos, his face blank, drooling as he moaned and wriggled between brain filling pleasure far beyond what most people could even imagine, never mind experience.
It was a long walk back down and through the structure, just to reach the ground the other side of his huge body, and even further back to the nearest unevacuated town to start writing up my article.
