Log One

A new type of virus has been brought to the research facility. Codenamed "K-R00" the origin of this virus seems to stem from the continent of Australia. Reports indicate that the initial carrier was located deep within the outback wild lands of the desert. However due to its level of hostility it had to be neutralized. A sample of the subject's blood, along with the autopsy of the remains has been brought to the facility. The remains themselves were disposed of for unknown reasons. All security and biohazard precautions have been put into place and a small team of twenty researchers have been gathered to study the virus and find any military applications and vaccinations

Log Three

Research has gone well so far with a lot of progress being made. Initial tests have shown that the virus has unique resistant properties that may make it difficult to create a vaccine.

_ _

Log Six

Infection and transmission scenarios have been run to scale the level of the virus's lethality. Secondary tests are being conducted at the moment, but initial results show that the virus can be transmitted through the blood, air, water and bodily fluids.

Log Twelve

Progress has grinded to a halt on the vaccination for the virus. All tests seem to show that the virus works the same way as most others do, however there does not seem to be a response from the hosts white blood cells. Further studies are being conducted, but current results show that a cure may be a long way away.

Log Twenty Three

After a long night of unsuccessful results the team began to grow frustrated and irate. Arguments began to flare up and some researchers were beginning to let loose some of their opinions of their co-workers. The shouting increased to a near deafening level before a vial containing a sample of the virus that was improperly stored fell from one of the tables and smashed onto the ground. The arguments stopped immediately afterwards as we were told that we were being put on lock down.

Log Twenty Four

Tests have been concluded, all scientists within the research team have been confirmed to have been infected.

Log Twenty Five

We are all being kept on lock down until it has been deemed safe for us to leave the building. Testing still continues even with the threat of a potentially deadly virus on the loose. Still the other scientists seem unphased. In fact morale seems to have improved.

Log Twenty Six

A rather embarrassing moment for Doctors Mike and Andrew. It seemed that the "cabin fever" got to the both of them and they were discovered in a rather compromising position in the bunk room. We all had a good laugh about it.

Log Twenty Seven

Another "hook up" seems to have occurred last night, although this time it was Doctors Fredrick and Alexander along with Doctor Felix. Stress under lock down has been getting to a few of the other doctors and I get the feeling that this won't be the end of it. However I have now suddenly begun to realize that this research team consists of only males. Perhaps other female researchers were unavailable? Or was this a precaution to prevent any events between opposite sex like what had been done last night?

_ _

_ _

Log Twenty Nine

Well it wasn't long after that when I decided to join in with the fun. I had a nice time with Doctor Andrew, and I had no idea that Doctor Richard was so well endowed. Dick would be an appropriate nickname indeed.

Log Thirty

Panic had broken out once again. Now that the sexual encounters seemed to have become the norm amongst the team, no one seemed to bat an eye when two of our colleagues were making out while tests were being run. The initial contact seemed innocent enough, but as the two then began getting very rough with one another people began to take notice. Clothes where soon thrown about everywhere and the two doctors seemed to pay no mind to their fellow researchers as they consummated their relationship right there on the table. However, through mid-intercourse a strange reaction began to happen to the two doctors. Thick pelts of fur began to cover the two of them and long extensions reminiscent of tails began to grow from their backsides. But one of the most radical changes was their feet, which grew to an enormous size before they became paw-like and tipped with black claws. By the time they had finished, the two once human doctors had become a strange hybrid of man and kangaroo. They quickly regained their senses soon afterword's and barricaded themselves in the bathroom to prevent any harm to anyone else.

Log Thirty Two

Another person had changed, this time while pleasuring himself. The symptoms of the virus seem to be a lowering of ones inhibitions followed by an increase in sexual desire. The two effects seem to grow in strength until culminating into the transformation of a kangaroo. The second researcher seemed to show little fear of harming his other co-workers after he had changed and even allowed us to measure his body dimensions. However, when he began making advances towards the other researchers we convinced him to join in with the other two who had already changed.

Log Thirty Five

More and more people seem to be changing at a steadily increasing rate. Some while partaking in carnal acts and others with little to no reason at all. As with all of the others who had changed; the standard transformation seems to increase the persons height, muscle mass, and stamina along with growth to the sexual organs. No reasons for how or what process is undertaken in the body's chemistry that triggers the change has been discovered. But with each researcher that changes, the progress on the vaccine slows to nearly nothing. I myself have been beginning to loose interest in discovering a cure and have grown more fascinated in studying some of those sexy roo's....

***************

"Vital signs normal."

"Heartbeat steady."

"X-rays show that the infected subject shows no signs of skeletal damage or strain."

"Excuse me! I have a name you know!"

A brief chuckle echoed through the speakers of the observation deck above the lab before the scientist continued.

"X-rays show that Doctor Samuel shows no signs of skeletal damage or strain."

"That's better."

From high above the glass roofed lab, Gregory Tyre, the owner and head researcher for the Orion Research Facility looked down upon the scientists as they worked with their different instruments. All of the researchers were dressed in yellow hazmat suits, fitted with small microphones in each helmet that allowed easier communication throughout the lab. There was also a heavy security presence in and around the lab as well, with several armed guards standing right outside the doors, along with several armed security agents inside dressed in black hazmat suits with special stun guns holstered at their sides. A necessary precaution given the circumstances. However there had been no real incident after the initial containment breach and the movement of the infected to a more secure lab. It was truly a godsend that somehow the subjects had maintained their wits after going through such trauma.

"Can I get off this damned table yet?" the subject complained.

"Almost, we just need to take another blood sample and measure your dimensions." Said one of the scientists

"Again?" the subject complained as a scientist approached with a needle.

"We just need to see how the virus is affecting your DNA." He responded as he gave the tip of the long needle a flick.

"Don't be such a baby." He continued as he slowly approached the subject.

Smirking slightly, Greg was surprised how well the other scientists had handled being given such a unique case. Especially since this one which had hit so close to home. Still that may very well be why every member of the team was so driven. It was their friends and co-workers that needed their help and they would do anything in their power to save them.

"Alright, now that ought to do it. Now just stand up for a moment and you will be free to go."

"Finally..." said the subject.

Greg's attention was perked as the subject finally came out from his blind spot from the observation deck and he could finally get a clear view of him. Stepping away for a brief moment he pressed a few buttons on a nearby console and a LED screen lit up in a corner of the window, giving him a closer view of the lab below.

He stood tall, taller than anyone there at a whopping 7 feet and 8 inches. His body was firmly packed with muscle from what could be seen through his patient scrubs and his tail stood out about 4 feet from his body. Covered in a soft coating of sandy colored fur with brown stripes across his arms and legs, the subject who had once been a fellow researcher at that very facility stood out with his arms stretched as several doctors approached with measuring tape.

A strange hybrid of kangaroo and man.

When the virus had been brought to the facility, it was to be a grand opportunity to gain military contracts and further funding. However, when a containment breach had occurred, an entire team was infected with what most assumed could have been the next world ending virus. Instead though, a miracle happened. Or at least the closest thing that could ever be considered a miracle in the scientific world.

It all began with the researchers beginning to grow more and more...promiscuous as the lock down endured until some inter-office relationships began to develop.

Especially those of the carnal nature.

That only served as the precursor to a more amazing discovery. For one day, after two of the scientists decided to throw all decency and concept of inhibitions to the wind, a radical transformation overtook them. Now they were all kangaroos, incredibly fit and nearly insatiably horny kangaroos.

The process has still yet to be understood, and that's just what the researchers are working on right now. Their hopes would be that they could find some way to reverse the process, or somehow alter the virus to change them back to their original forms. Progress was slow due the virus's highly infectious nature and stubborn defences, but in time he knew they would unlock its secrets. The one thing that troubled him was that the researchers who were initially involved and infected didn't seem to be in much of a hurry to change back.

"Arms at 27.2 inches"

"Legs at 35.5 inches"

"Chest is at...damn...68.9 inches"

"See something you like?" Doctor Sam said with a cheeky grin.

The scientist chuckled softly at that comment and went back to work, until finally they all stood back.

"Alright, you know the drill, drop it." One of the scientists said.

"Mmm...my favorite part..." he stated with a lustful grin

As if he was trying to make a display out of it, the kangaroo man reached back and slowly un-did the ties of his patient scrubs and let them fall down onto the floor, leaving him naked for all to see. One could really see how clearly defined this specimen was now, with clear cut abdominals and solid pectorals that stood out proudly from underneath his fur coat. Though in most cases, no one stared at those assets for long when a more glaring addition was brought into view.

Where with most kangaroos in the wild had what most would call "reversed junk" the scientists all seemed to retain the order and shape of their anatomy even after their transformation. However, they now all sported sheathes which housed their enlarged members when not in use...which was a rare moment indeed.

Reaching down and slowly groping himself, Doctor Samuel began to rub at his sheath to stimulate his hidden organ from its hiding place. The sight was a common one with all of the regular physicals that each of the twenty researchers had to undergo, but no matter what they always tried to make a showing out of it. Each one seemed to have their own favorite "routine" that they played out whenever measurements had to be taken of their cocks. With some acting more blunt and going straight for the finish, while others seemed to love teasing themselves or the observer. Sam's particular "move" was when he sat down and used one of his massive feet to gently rub at his pole as it began to emerge.

"Alright hot stuff, that should be enough." Said one of the scientists as they reached up to pull Doctor Samuels hand away from his pole before he begun one of his famous marathon jack-off sessions in the middle of the lab again.

Working quickly, the scientist measured the length and width of the kangaroos cock before grabbing a note-pad and recording the dimensions.

"Fourteen inches long and four wide. My aren't we a big boy." Said the scientist as they set the pad aside.

"The better to fill you with my dear..." said the kangaroo with a cocky smirk as the mushroom shaped head of his cock let loose a drop of precum.

Another scientist quickly reached up and slapped the kangaroo on the back and pushed him towards the security gate.

"Alright alright you're free to go now. Go "unwind" before we gotta get the cleaning crew down here again.

Letting out a chuckle the kangaroo smirked as he cockily swaggered towards the gate where a security guard stood nearby, cautiously gripping onto his gun.

Greg let out a chuckle of his own as he pressed the same key on the console and the screen suddenly went out. Gathering his things and adjusting his own lab coat, he quietly made his way down their stairs and out through the secure door into the main walkway of the building.

Once a nuclear missile silo, this hole had been converted into a spiraling structure that buried itself deep within the earth. There were several levels for observation and for different branches of research, but all attention and funds had been recently been directed to this new discovery. The initial announcement was met with some resistance and arguments by the department heads, but that was before they were introduced to some of the subjects.

After that it nearly became a bidding war for who could work on the project.

Slowly making his way downwards, he was approached by several different researchers who tried to stop him and ask him some random question or request for some piece of new equipment. He brushed them all off, a habit in which he hoped to break himself of soon, but with a big project like this going on, he couldn't spare much time on any other branch.

Passing through several different barriers and checkpoints, he met up with some of the researchers from the lab just after they had been de-contaminated. Many of them greeted him happily and told him of the strides they had made in identifying the inner workings of the virus. Greg offered them a few words of encouragement and gave a few pats on the shoulder but he then quickly excused himself as he made his way to the lowest portion of the facility.

After passing security clearance once final time he found himself in a large room with a massive window that showed the inside of the housing that had been prepared for the subjects. Given the history of those who had been infected, no expense was spared in providing those who had once been the most esteemed and well liked researchers with comfortable accommodations.

*SPLAT!*

The water proofing and bullet proof glass was also wise investment indeed.

As he watched through the observation glass, he saw what could only be described as the aftermath of the world's biggest orgy. However this was an orgy that never seemed to have any end in sight. The kangaroo men were scattered throughout the room, some paired together and fucking over the furniture, while others gathered into large piles of fur, muscle and semen in different corners of the room.

Sleep, eat, fuck, repeat.

That seemed to be what the general mindset for every researcher that had been infected and changed. They did seem to be in control of their senses, and they did follow orders and directions when told. Though to most it would just seem that their nearly constant love making was just a way of passing the time. Or it may just have something to do with the virus. Hopefully the recent tests may give some explanation to that at least.

"Doctor Richard, could you come to the window please?" said Gregory as he pressed a button on a nearby intercom.

A set of ears poked up from behind a nearby couch set as a kangaroo covered in black fur stood up and licked his lips before he bounded towards the observation window on his massive feet. Doctor Richard was one of the first in the group that transformed and was undeniably the biggest in every sense of the word. Built like a tank he nearly stood tall enough to be out of sight of the massive wall of bulletproof glass. His fur was also nearly entirely black, save for the slightly lighter tone that covered his chest and the few streaks that crossed his legs.

"Hey there Sir, what do you need?" he asked with a grin before he looked down at his own throbbing erection.

"Oops! Err...sorry! You know how it is...."

Reaching down he attempted to cover himself, but the 18 inch slab of meat that he sported nearly reached up to his pectorals and would rarely ever go back down. Some scientists were even worried about the near constant erection he sported, but from all appearances through his vital signs everything seemed to be normal. Or at least as normal as a ten foot tall kangaroo man could be.

"It's alright Richard I understand. How are you feeling today?" Doctor Gregory asked.

"Me? Oh I'm good, I'm good. Me and the other guys are getting along well and I'm down to only 8 ejaculations in the past day. It would have been six, but Drew and Sam came up to me and well..."

"No explanations needed." Said Doctor Greg as he lifted up a single hand and smiled at the shy looking behemoth.

"Heh...thanks...so how is that cure coming along?" he asked as he began to relax.

"Still a ways away unfortunately, this virus is a tough nut to crack, but I'm sure we will figure it out eventually." Doctor Greg stated with a soft sigh.

"Well there is no rush in it, everyone here seems to be happy enough right now...I mean look at us!" Richard said with a grin as he rose up his right arm and playfully flexed, showing off his powerful muscles and thick veins.

"Yes yes, so you have told us multiple times. Although you don't want to be locked up in there forever now do you? I mean you know how contagious you are." Greg said with a frown.

"Well I don't think people would complain being this huge...but you do whatever you think is best." Said Richard as he lowered his arms and tweaked his long ears.

"Don't worry; we will get a cure sorted out soon." Greg said affirmatively.

"I'm sure you guys will...but hey, can I ask a favor?" said Richard softly

"Sure, what is it?" Doctor Greg responded.

"Can you tell mom that I miss her? And that I'm sorry that I haven't been there in a while?"

Doctor Greg flinched slightly, but then he softly nodded his head and smiled.

"I'll be sure to pass along the message."

"Thanks, dad..."

*************

It was several hours later when Doctor Gregory made his way back to his office. His one place of peace and quiet after a long day of running data and checking on different experiments that had been running for nearly a week now. Letting out a sigh he sat in his chair and looked towards the photo that he had kept with him for every job he had ever had. The picture was that of a smiling and happy family, a young man with dark black hair and his beautiful wife with rosy red curls holding up a small baby boy wrapped in a blue blanket. However, these days that same young man had felt the march of his age with his hairline slowly receding and what remaining of his hair turning a light shade of grey. Also with many hours spent browsing through reports and medical textbooks; wrinkles were already forming on his brow and his hands seemed almost bony and dry. His body had also seen better days sense becoming the head researcher at the facility, but that came with the position that had so much and so many people depending on him.

"Sarah, what am I going to do? Our boy is healthy, but not even human anymore. I'm glad to know that this virus hasn't killed him yet, but what if it does? What if it spreads? What if because of me, an epidemic occurs that may very well mark the end of humanity as we know it?"

Letting out a sigh, he leaned back in his chair and looked up towards the ceiling fan in the room.

It had only been four years ago, but the pain was still so fresh. He had just lost his own wife, what would he do if he lost his son as well? Letting out another deep sigh he sat back down normally and looked at the scattered pieces of paper that had been placed there throughout the day. He didn't even bother giving any of them a second glance as he pushed them aside and he laid his head down on his desk.

"What to do...what to do..." he muttered to himself as he removed his glasses and closed his eyes, trying to comb through his mind for a solution.

Every possible experiment had been run and everything known to medical science had been procured. When the government had been informed of what this virus's capability's where, funding became no issue whatsoever. In the back of his mind Greg did worry what would happen to the virus once the military got their hands on it, but that would still be a long ways away.

"Gotta run those amino acid tests in the morning...and maybe run a few more blood samples by the radiation ward..."

Greg muttered to himself for a few moments as he slowly felt his mind begin to drift and his body began to relax.

"Need to find out what engineering has figured out with that new laser...and...*yawn* talk to medical about the..."

Before he could even finish his sentence, the Doctor began to drift off to sleep. A long day of stress and worry had worn on him, and his body was unable to keep the pace as much as it had used to.

*********************

"Mmmm...."

"Awwww fuck...."

"Yea....."

Down in the observation room, several guards looked on as three of the roo's continued their lovemaking while the rest had retired to their quarters. With one cock in his muzzle and another filling his hole, Doctor Samuel stood between doctors Michael and Richards as he was being doubled stuffed by two of the largest kangaroos in the group.

"Fuck you have a tight hole...." Muttered Michael as he pounded away into Doctor Sam, who only moaned in response.

"Mmmm...." Doctor Richards said as his own massive pole was lathered in licks and the occasional suckle by the horny kangaroo.

The guards continued watching this for some time, some with visions of disgust while others looked on curiously. A few of the other guards had even excused themselves after watching the show for a while until only two were left observing.

"Fuckers must be jacking off after watching all this shit..." Muttered an older looking guard with crew cut hair and a furrowed brow.

"Hey, if you were sporting a pole that big, wouldn't you be fucking anything that moved?" the younger guard with a playful nudge.

The elder guard let out an annoyed grunt before he turned to face his co-worker.

"Maybe, but I'd rather be fucking some pussy instead. These gay roo boys don't do anything for me. Plus I mean why haven't they tried seeing if any chicks could get it as well? Do they not want little joeys around or some shit?"

The other guard only shrugged as the first let out another grunt and returned to his post.

"Ooooooohhhh...." Moaned Doctor Richards as Sam took in another inch of his massive pole.

Michael hadn't let up either and was furiously pounding the doctor's rump, all while holding up his muscular tail and gripping onto his firm rump.

"Fuck I'm getting close..." muttered Michael as he began to thrust faster and faster.

Richard seemed to be getting close as well, and had begun playing with his nipples that stood out from underneath his thick, dark fur.

This kept on for only a few more moments and just as the kangaroos where right at the edge of getting off a sudden scream echoed through the room. Letting out shouts of their own, the two kangaroos stepped back in fear to reveal that Doctor Samuel had fallen to the ground and had begun twitching erratically.

"Holy shit! We gotta get down there!" said the younger guard as he quickly bolted for his locker and hastily put on his black hazmat suit while the other guard followed behind.

Cutting through a maintenance hallway, the two guards dashed through several doors until they came up to the main security checkpoint, which was left strangely unguarded.

"What the...fuck where is the guard?! Ok you stay here and I'll go check on him." Said the second guard as he reached up and pressed his key card onto the scanner, causing the door to let out a confirming beep before slowly opening.

"Be careful in there Dee, don't let any of those fuckers get the drop on you." Said the elder guard as he gripped his rifle tightly and glared at the kangaroos through the bulletproof glass.

The two kangaroos looked shocked and afraid as they looked down at the twitching form of Doctor Samuel as the guard entered the living quarters.

"Move back!" he shouted as he pushed the two of them aside and kneeled down to check for a pulse.

1...

2...

3 ...

"Dammit...no pulse! Has he been acting strange at all today? Anything out of the normal for you guys?" Dee said through the microphone of his suit.

"No! We were just having some fun and then he was like this!" said the taller black kangaroo as he clenched his hands nervously.

"Dammit...alright I'm going to call in a gurney and have him taken to the lab."

Dee then turned around and took a step away from the subject before he reached up and pressed a button on the side of his suit that activated the all-call system.

"This is Lieutenant Dietmar down in the living quarters for the infected subjects. I request immediate medical attention for one of the subjects who seems to be suffering from a stroke".

After a few moments, the dispatcher responded.

"Copy that, sending medical aid now. Activating emergency procedures" Said a voice through the speakers before the room was suddenly bathed in a red light as the emergency signals began to flash.

Dee let out a nervous sigh as he heard the locks of the doors beep. He knew he would be locked in until someone with a higher level of clearance came to shut down the lock down, so until then he had to do his best to calm the subjects. Seeing something like this would have been a major shock to them, and could very well foretell their future if they didn't find a cure soon.

*Boom! Boom! Boom!*

The sound of banging suddenly echoed through the room and Dee turned his attention towards the door where the other guard was frantically banging on the bullet proof glass with the butt of his gun. He seemed to be shouting something and he was pointing directly towards him, all while still desperately trying to break in. Dee raised an eyebrow at the strange sight before he felt a chill run down his spine. Carefully reaching for his sidearm, he slowly turned around to face the other infected subjects.

"Alright... just wait here and give the medical doctors a wide birth-"

As Dietmar turned around, he was suddenly met with three massive kangaroo's staring down at him with sinister grins plastered on their faces; including the one who had a "seizure" just a few moments ago.

He didn't get a chance to draw his weapon before it was torn from his side and two sets of massive paws gripped onto his arms and shoulders. The one kangaroo that seemed to have faked an injury then slowly approached with a sinister grin as he rose up a claw tipped finger.

"Time for you to join the club...." Doctor Samuel cooed softly.

Slowly reaching forward, Doctor cut through the oxygen hose supplying air through the thick hazmat suit to the guardsman. Within mere moments Dee could smell what the room was like, and it reeked of sex, cum, and fur.

Another chill ran down his spine as the sudden memory of the words spoken during security briefing ran through his mind.

"The virus can travel through the air, blood, water, and bodily fluids".

"Oh shit...." Dee muttered

The two large kangaroo's holding him down then suddenly reached and gripped onto opposite ends of the hazmat suit. With one powerful tug they tore the protective fabric in two, and pulled the helmet off of the guards head.

"What are you? Wait...my suit! I'm infected!" Dee stated in a frightened tone as he looked down at his normal uniform, feeling practically naked even though he was still fully dressed.

Before he could get out another word, a pair of lips then suddenly met his own and Dee felt like he had been hit with a bolt of lightning. The creature forced his tongue down his mouth, swirling it around with the skill of an expert while he was gently embraced by the large kangaroo. Panic shot through Dee's mind as he began to imagine just what he virus was going to do to him. Would he end up like the rest of them? Would he be a kangaroo forever? Would he be as big and buff as the other studs he was surrounded by?

With that last thought, Dee's mind began to grow more relaxed and muddled as he began to accept the kangaroo's advances upon him. The virus had already gotten into his system and he was a doomed man. His inhibitions had already begun to drop and he could feel his groin stirring through his combat pants.

After only a few moments, the forced advancement of the kangaroo became a passionate make out session between the two as the security guard moaned slightly in the kangaroos hold. As soon as it had become apparent that he would show no resistance, the kangaroo known as Doctor Michael loosened his grip on the guard and set him down before breaking lip contact with him.

Looking up at the three roos in a daze, the guard's mind felt hazy and clouded with an assortment of new sensations that were tingling across his body. Before he could even begin to process them the largest roo stood forward with his massive cock throbbing in front of him and drooling a steady stream of precum onto the floor.

"Ohh...fuck..." Dietmar moaned as he reached out with one hand and gripped onto the massive pole, while his other hand reached over to explore the kangaroo's defined features.

Each muscle felt as though it was carved from stone, yet the outer layer was so soft and warm, with a feeling of comfort that Dee could only describe as the feeling of a warm blanket. As Dee began to trace the valleys between the kangaroo's muscles his other hand was already being coated in precum and he could feel his body tingling and his arousal building. Finally throwing all caution to the wind, he let go of the creatures cock for a moment before he embraced the kangaroo and nuzzled his fuzzy stomach, all while the beasts cock drooled down a river of precum that had begun to soak into his clothes.

The kangaroo let out a soft chuckle at the guards sudden affection as he reached down and ruffled his brown hair before positioning his face right into the flesh of his cock. The guard looked right at the pole for the briefest of moments before he looked up at the kangaroo with a pleading look in his eyes. Doctor Richards smiled and nodded in affirmation and the guards face was suddenly plastered with a smile.

Looking at the pole in front of him, Dee gazed in awe of the sheer size and thickness of the member. It was bigger than anything he could have imagined, and much bigger than anything he could have taken. Slowly inching forward, he stuck out his tongue and gave the kangaroos cock a long, sensual lick that barely even covered a small portion of his member.

Doctor Richards grunted slightly in pleasure as the two other kangaroos watched on, with their own cocks standing at full mast while they jerked off to the show.

After that first lick, Dee began peppering the massive pole with hisses, his lips tasting the infectious precum with nearly every contact while the pole still continued to produce more.

He wanted more, he wanted to have that massive beast inside of him, but still somewhere he knew that he could never take a cock of this size...at least not yet.

Within his mind he knew what caused the infection and he knew what the symptoms of the disease were. But after being told just what sorts of things he should avoid, he began to do the exact opposite in a frantic attempt to spark his changes. What was once left of his resistances had now faded away and all he wanted to do now was become as big and buff as the other kangaroos around him.

Dee struggled slightly with the pole, licking the shaft like a lollypop he couldn't fit in his mouth while he reached down to undo the zipper of his combat pants. He thanked whatever reasoning he had earlier that day that made him choose to go commando that morning and his throbbing erection was let loose with little effort. Dee then reached down and began frantically stroking himself while worshiping the pole in front of him, his own cock throbbing in his grip as he furiously jacked off to the image of what he was to become. After this did not seem to work after a few moments, Dee reached down to un-button his pants before he was suddenly racked with a wave of pleasure.

He grinned.

This was it

This would be the moment.

The other kangaroos watched on in amusement as another person joined their group. However they failed to notice the other guard who was still frantically trying to make his way in. Looking around in a panic he seemed lost for hope until he found a large metal pipe that had been left over from the areas construction.

Dee felt it, the warm glow, the feeling of power rushing through his veins. His clothes began to feel tight and he reluctantly pulled away from the beasts cock so that he could unbutton the first few buttons on his jacket. But before he could get past the first two, he was suddenly stopped by the presence of another kangaroo's foot paw as it rubbed across his member. Dee let out a pleasured moan as he began to kneel, all while Doctor Sam slowly rubbed the guardsman's dick with the softest part of his foot.

Dee was in heaven, although as he looked down at his cock he felt slightly emasculated when he compared it to the size of the kangaroo's massive feet. Something he hoped would be remedied soon by the onset of changes he was already beginning to experience.

Underneath his military grade jacket, his body was already beginning to expand as a dusty coating of brown fur began to sprout across his chest and spread across his body in a wave. His feet were also beginning to swell at a rapid pace and his boots were already beginning to feel the strain. Finally the seat of his pants was already beginning to swell with new found muscle as a small protrusion began to grow from his backside.

"More...more..." Dee moaned as he reached down and fully unbuttoned his jacket, casting it aside and tearing off his undershirt to reveal the growing pelt of fur he was sporting.

The kangaroos seemed all too eager to comply as the three of them surrounded Dietmar with their massive cocks pointed directly towards him and sending droplets of their infected precum raining down upon him.

*Clang! Clang! Clang! Crack!*

While the kangaroo's focused their attention on the guard, they didn't notice that the other guard had begun to make some headway towards breaking through the glass. Small cracks had already begun to appear across the bulletproof glass and he kept smashing at it with little restraint.

Meanwhile, Dietmar was completely enraptured in his changes as his body began to swell with power. While his chest began to grow and expand with newfound strength, the fur covering his body began to make its way down to his legs, which sparked a whole new series of changes. Bones began to grow longer and stronger as the guard gained and extra two feet in height while his pants began to tear at the seams as his legs grew thick with muscle.

Letting out a lust filled moan, Dee grabbed the nearest cock to him, and took the mushroom tipped head into his changing mouth and suckled with wild abandon. Richard and the other kangaroos smirked at his eagerness and began to stroke their own poles, sending more precum down onto the guard as his body began to grow and shift under the influence of the powerful virus.

*Rriiiiiiiiiip!*

The seat of the guard's pants finally gave way as a fleshy protrusion that would soon become his new tail let itself free. The fur had already begun to cover his fledgling tail, and his legs would soon be complete. His hips then began to expand slightly as his muscular legs filled with more muscle, making them perfect for jumping or hopping across the plains. Finally then, his combat boots could take no more as the leather tore to shreds as two massive feet burst through, tipped with claws and having already taken on the paw-like appearance of the other kangaroos.

"Looks like the little joey is almost done...let's give him a gift boys." Said Doctor Sam as the other two kangaroos nodded in affirmation as they began to stroke their members even faster.

Dee even pulled himself away from one of the roo's massive cocks as he looked down at his new feet, reaching over to feel the soft, warm feeling of his new fur before reaching up to feel his new chest as it swelled with muscle. It wasn't soon then after that he was nearly as defined as the others, and sported a set of pec's and abs that would many any straight man turn.

The kangaroo's above him began to grunt wildly as they got closer and closer to the edge, Dee smiled and opened his mouth wide just as the fur began snaking up his neck, covering his face in the same chocolate brown fur that covered the rest of his body. His ears began to migrate upwards and grow long and pointed like his kangaroo brethren. His face also finally began to expand into a proper muzzle with his nose turning dark and wet as his face lengthened. Finally then, in one surge of growth, the former security officers cock had a surge of growth, passing 8...10...and finally stopping at a massive 15 inches before the base was wrapped up in a soft, protective layer of skin that would serve as his new sheathe.

The moaning and grunting got louder and louder and soon Dee joined in the circle jerk with his new massive cock in hand, basking in the pleasures of his new form.

"Awww...fuck...."

"Fuck!"

"I'm cumming!"

One after another, the other kangaroos showered the new recruit in their corruptive sperm, covering his chocolate brown in their white, sticky fluids.

Dee kept at it though, still working his shaft, still looking for that right feeling. He was a kangaroo now and he knew he would have to make this one a memorable shot. Reaching down he rubbed his chest and soaked himself in the kangaroo's sperm while he brought himself closer and closer to the edge.

"Awww fuck...aww fuck!"

And with a mighty shout, Dietmar the security guard was no more as Dee let loose his first shot as a muscular brown kangaroo.

He fired off volley after volley of cum, nearly hitting the ceiling and arching well across the room. His fellow roo's seemed impressed, and offered him a few whistles and hoots of accomplishment. When the orgasm high finally died down, Dee somehow was able to pull himself to his enlarged feet, and stood at nearly the same height of two of his new brothers. However the kangaroo Richard still towered over the three of them.

"Impressive shot..." said Doctor Michael.

"You make for a sexy roo" said Doctor Samuel.

Richard only smiled and nodded as he looked down at the roo and placed a paw on his head and ruffled his hair like he had done before.

*Boom! Boom! Boom! CRASH!*

The four roo's turned around to see a man in a black hazmat suit holding up a rifle and pointing it towards them all. In his other hand he held a bent metal pipe and all around him were the shattered fragments of glass of the door that was the only thing separating them with the outside world.

"You little fuckers are going to pay!" shouted the man from inside the suit.

The four kangaroos looked at each other for a brief moment before they all broke out into sly grins.

It was time to add a few more people to their little group.

*********************

WARNING! WARNING! EMERGENCY PROCEDURES ACTIVATED! WARNING! WARNING!

Doctor Greg was suddenly knocked from his sleep as the emergency lock down had begun and had bathed his room in a red light. The intercom kept blaring the same message over and over, but Doctor Greg only thought of one thing.

"Richard!"

Grabbing his lab coat and key card, he bolted out of his lab to find many of the scientists being escorted by armed security officers into different segments of the facility. When he saw the medical team rush by with a gurney and life support systems dressed in hazmat suits, he knew only one place they could be going.

Making a break for one of the side-hallways, Doctor Greg passed by multiple security checkpoints through a path that only he was allowed to use and was aware of to make his way to the lower levels of the facility. After climbing down several flights of stairs and a few confusing twists and turns, he found himself in the old observation deck situated above the infected housing, which had multiple pieces of equipment and boxes blocking the only exit down after the creation of the lower observation room.

Growling slightly, he tried to pull some of the machinery out of the way, but there was a lot of it, and most of it was very heavy. After struggling with a few boxes, he let out a gasp of exhaustion before he turned his attention towards the intercom button near one of the windows.

Racing towards it, he furiously pressed onto the button and began to shout.

"This is Doctor Gregory Tyre! What is going on down there!?!"

There was a slight delay in the response before suddenly the sound of metal hitting the bullet proof glass began to echo through the speakers.

"This is Officer Drake Hallard!" *CLANG!*

"After responding to an incident,lieutenant Dietmar was locked in with the infected subjects!" *CLANG CLANG!!*

"The bastards where just playing possum though! And they jumped him and destroyed his suits! Now those bastards have infected him!" *CLANG!*

Doctor Gregory let out a gasp as he looked down into the room. He could see the other subjects stirring in their rooms, but out in the living quarters there was a single man surrounded by three kangaroos.

One of them was Richard.

"Richard...no..." he muttered softly.

*CLANG! CLANG! CLANG!*

The sound of the officers attempts to breach through the door continued to echo through the speakers. Doctor Greg then pressed on the speaker once again.

"Officer! Stop damaging the door! You will cause a containment breach!" shouted Greg through the speaker.

"I'm not leaving him in there!" the officer responded back before he let out a loud yell and a particularly sickening sound echoed through the speakers.

It sounded like ice breaking as a ship smashed through it across the seas. Greg could almost picture the cracks in the door before it shattered into a million pieces and fell to the floor.

"You idiot! You have doomed us all!" Greg shouted through the speaker before he turned around to look down from the window.

Greg saw as the officer stepped into the room and pointed the rifle towards the kangaroos. He appeared to be shouting something and the kangaroos seemed to be complying. However what the officer didn't notice was another kangaroo that was hiding behind the wall, waiting for him to take just a few steps forward. Greg wanted to warn the man, but within mere moments it was already too late. The man rushed forward before being tripped by another kangaroo, sending his gun skittering across the floor. The others then quickly pounced upon him, tearing his suit to shreds and exposing him to the airborne virus.

Within moments he was already beginning to give in. The newly transformed kangaroo that now sported his old military jacket seemed to give him extra attention as he pounced on top of him and began doing god only knows what.

Greg had to do something; he had to contain this before more people would be infected. But the first thing that came to mind would be to destroy the subjects.

But could he do it?

Could he kill his own son?

*********************

"Ohhhhh.....fuck...."

"That's right Drake...don't that feel good?" said Dee as he reached down and gripped onto the officer's cock and gave it a playful stroke.

After their little scuffle, Dee's partner quickly gave in and was now bent over the couch with his transformations well underway. Unlike Dee's chocolate brown fur with tan stripes across his chest and back, his fur was a smokey grey color with black splotches on his rear and abs. He was also very powerfully built, although a bit shorter than the other kangaroos. He was definitely built for strength but not for speed. As Dee thrust into his partner once again, Richard and the other Roo's had gathered around in the living room as he began to shout out orders.

"Keep to the hallways, the main paths will be heavily guarded. Someone just needs to make their way to the air filtration system and sabotage it. After that, things will be easy." Richard stated with a grin as he rose up his fist to the air.

The other roo's cheered as they made their way out of their prison and went out into the facility. Some forming small groups while others went at it alone to cause a distraction. Dee figured he would join them soon, but not until he finished up with what he was doing.

"Awww...fuck Dee I'm gonna cum..." moaned Drake just as his muzzle began to form and the last few pieces of his transformation began to set in.

Dee smirked, watching his homophobic co-worker so easily turned after this. Getting to the rest of the guards would be easy with his knowledge of patrols and emergency procedures. With the sudden setting of the lock down with little training after no incident, dispatch had to be slower and many would be lost and confused. Richard couldn't have planned this breakout any better.

Giving his partner a few more thrusts, Drake let out a loud moan as his cock finished its changes and he spent his load all over the couch. Dee didn't last too much longer after that and he spent his own creamy load deep into his co-workers insides. The two of them stood there for a few moments, panting and gasping for breath before Dee slowly slid his member from out of his partner, letting loose a torrent of cum from his ass.

"Shit...I see what you meant about fucking anything that moves man..." said Drake as he stood up and stretched his back after being bent over for so long.

"Yea, it's great isn't it? And the best part is, there is a whole lab full of nerds just waiting to be made into studs like ourselves." Said Dee with a grin as he reached over and gave Drakes ass a playful grope.

The grey kangaroo chuckled slightly as he turned to face the man who had changed him, his cock still dripping with the load he had spent only a few moments ago.

"Well then, we better get to work."

****************

INFECTION! INFECTION! All Personnel to quarantine! INFECTION! INFECTION!

Doctor Greg rushed to the nearest locker room he could find and put on a hazmat suit. He urged others to follow suit, but many of the doctors were in a panic and most of the security guards wouldn't let them out of quarantine.

As Doctor Greg rushed up towards the higher levels of the facility, he was constantly stalled by security checkpoints, which required him to flash his badge before the door would open. But behind him he could hear what was going on. Shots were fired and he could hear people screaming and crying out for help before they were quickly silenced. After a few more minutes the air conditioning system across the entire hallway let out a strange grinding sound before starting up again.

"No...they sabotaged it!"

As he made his way past another checkpoint he was suddenly met with a group of guards shepherding some scientists into a nearby hallway. Everyone looked frightened and concerned for whatever was going on, but then suddenly one of the guards doubled over in pain...or was it pleasure?

Soon after the guard pounced upon his co-worker and began rapidly tearing away at his clothes. The two of them then began sprouting thick coats of fur and began making love right there in the hallway. The researchers all screamed and half charged their way into the room while the others ran upwards. However, those who ran up didn't make it very far, and soon lab coats and clothing where being thrown to the wind as the scientists all began to pair up with each other as their body's underwent the transformation.

"No! No!" Doctor Greg cried as he pushed his way past the guards and the group who had chosen to run. Passing through another checkpoint he found himself face to face with a small group of kangaroos waiting in ambush. Most were nude, but some were wearing tattered lab coats and others wearing the torn remains of military jackets. But one thing they all seemed to have in common was they were definitely male...

And they wanted to play...

****************

"What do we do!?! What do we do?" Cried out one of the researchers from inside the quarantine they had erected in one of the staff lounge rooms.

"Are we going to be like them? Are we going to turn into monsters?" responded another.

"Well I don't think that would be too bad...."

The final researcher was slapped by an unknown hand and was quickly silenced as the rest of the group huddled in fear in the far corner of the lab.

The sound of screaming and cries of ecstasy could be heard from outside the door. Shots could also be heard, but as time went on, the shots became fewer and fewer. The researchers were paralyzed in fear and kept completely silent...waiting for whatever would come next.

The sudden rattling of the door handle caused one researcher to scream, before another one quickly covered his mouth. Whoever was outside then began to bang on the door, trying to find some way of getting in. But after a few moments, the shaking stopped and the sound of footsteps could be heard. They appeared safe...for now.

"Awww...fuck..." moaned one of the researchers.

The group suddenly split in two, leaving a single researcher who had already unbuttoned his fly and was furiously jerking off while tweaking his nipples through his lab coat. One man screamed as he tried to push his way through the crowd until he was standing next to the infected subject. The rest of them gave the two of them a wide birth as they watched on in fear.

"David! David please hun you have to fight it! Please!" the man shouted to his changing friend.

"So...horny..." the man responded before he began to un-button his jacket with his free hand while still working his cock.

"No! You have to fight it! You have to fight it!" the other man cried out as he tried to pull his partners hand away from his cock, with little result.

The man kept stroking away at his own cock, fur already beginning to spread across his arms and whatever exposed flesh the other researchers could see. It wasn't then soon long after the man who had begged and pleaded with the man to stop began to join in. Soon then the two men sat there naked, one sucking off the other in a bizarre 69 while their bodies began to bulk up and their tails began to grow in. The two of them rapidly began to increase in mass, and the warmth the two of them where emanating began to have an effect on the others.

Soon then another scientist began to give in as he jerked off with little regard to whoever was around him. Then came another and another until finally one researcher broke away from the group and went towards the door.

*Click*

He unlocked the door and opened it wide, standing outside into the orgy that had broken out outside.

"Here! We're in here!" said the researcher with a sly grin before he reached down and unzipped his own pants as well.

A few other kangaroos in the hallway heard his shouts and quickly made their way towards the open door. The tall, muscular beasts smirked as they watched the onset of the orgy of researchers before a few of them broke away to cater to them.

It wouldn't be too long now...

*****************

*Thud*

Greg groaned as he was suddenly tossed from the shoulder of one kangaroo onto the floor of the main observation deck.

He tried to struggle, he tried to get free, but the beasts were far too strong. So he was left there to watch as he was carried up higher and higher to the upper levels of the facility, all while watching people transform around him. Many were taken by force, with some kangaroos forcing the contaminant upon them through their sperm and precum. The rest were taken by the airport pathogen, but their changes seemed slower than most. But the disturbing thing that he was able to gather was that those who had only been exposed to the air seemed to seek out those who had already changed, as if they were seeking to complete what the virus had become.

"Hello Dad..."

Greg looked up to see the towering form of his son who had been turned into a kangaroo. His dark black hair had always been a noticeable quality to him, along with his deep blue eyes. Now that hair covered his entire body, but his bright blue eyes still shone through.

"I'm sorry about all this, but it was inevitable." He said with a slight hint of sadness in his voice, but the throbbing erection he sported suggested otherwise.

"Why?" Greg said softly.

"Because it's for the best. We don't want to be cured, and we want to show everyone how good this feels. You have seen the results for yourself. We had members on our team with health problems, diseases, STD's, and genetic deformity's they have had sense birth. Now look at us! Fit, powerful, virile and healthy. Isn't this what we have always been looking for? A cure for humanity's struggles?" Richard stated as he took another step towards his father.

"This is no cure...it is a disease! And you're not even human anymore! Are all these "benefits" as you call them worth your very humanity?" Greg argued as he looked up at the towering kangaroo that stood before them.

"You will soon find out for yourself."

*Snnnnnit!*

Greg gasped, like lightning his son had reached back and severed his oxygen supply. He could already smell the air of the outside world, and it reeked of sex. He was already beginning to feel woozy and tired after having run up and down the levels of the facility and he soon felt himself losing his balance.

But before he could fall, his son caught him and gently lifted him up and sat him on a nearby chair. Working carefully, Richard took off the helmet covering his father's tired features and unzipped the hazmat suit from his body.

Greg groaned as he felt his mind grow muddled and a strange stirring begin to grow in his pants as he looked up at his massive son. Soon he then began to feel his body tingle with energy and he looked down at his hands. The wear of age and time soon began to re-wind as his flesh gained its former youth and vigour. He then began to feel himself breathing easier as his chest began to tingle and his legs were suddenly filled with strength. Looking to his sides he saw his arms as they began to pump up with strength that he hadn't had in years. But before he could look any more, the sudden onset of long black hairs covered his vision.

Gregory gasped as he watched the clock turn backwards, he could feel the age marks on his face beginning to recede and his vision began to grow blurry with his glasses on. Reaching up and pulling them aside, he could suddenly see with surprising crispness and color that he hadn't seen in years. It was then that Richard came to his father, holding up a large mirror to show what he had become.

It was him.

The same young man from the picture.

The same man who had fallen in love, who had a son and a beautiful wife, the same one who was filled with an energy to change and improve the world.

But that man's face suddenly began to change, as a new addition began to creep out from under his shirt collar.

Fur.

Reaching down to unbutton himself, Greg watched as the fur slowly made its way across his hands and up his neck. By the time he had taken off his shirt, he was completely coated in dark black fur, just like his son's.

Looking over to him, Richard smiled in approval before Greg stood up and he set the mirror aside.

He could feel the changes, the power rushing through his limbs as he grew taller and more fit than he had ever been in his entire life. The sound of ripping fabric echoed through the room as his tail tore itself from its confines and his feet which had grown much too large for its shoes.

He knew what was happening, he knew he couldn't stop it, but at this point he knew his fate, and he knew what was to come next.

He just hoped his son wouldn't think any less of him for doing it.

Shamelessly unbuttoning his pants, he let his cock free as he kicked the khaki pants aside and slid off his old man underwear. He then began to masturbate, right there in front of his only son as he was becoming a kangaroo man just like him.

He let out a moan as the changes overtook him, his body growing taller and wider while his hips widened to befit a creature made for jumping. Soon then his muzzle began to come in, and the face of the young man disappeared to reveal the handsome visage of a stud kangaroo.

Finally the last changes set in as his cock grew, longer and longer his pole stretched until it nearly reached past his stomach and up to his pectorals. Then, with one final shout, he let loose a torrent of cum that fired across the room and landed onto his son's massive feet.

Gregory gasped for breath from the extreme experience, he had undergone a massive change just like the rest, but this time he was nearly as large as his son. It must be something in the genetics that had something to do with that. But before he could think any further, his son ran up and embraced him, their two massive cocks sandwiched between them.

"I'm sorry I did that dad...but now you see why I did?" Richard stated softly.

Greg grunted softly and tried to feign anger, which made his son frown in disappointment. But soon then after he let out a laugh and hugged his son even tighter than before.

"I suppose I see your point now. This isn't exactly something I would want to give up."

Richard smiled and nodded his head as he hugged his father back one final time before the two broke apart.

"Well then son, we still have several levels to get to, and I'm sure there are still a few stragglers around. What do you say we go out there and have some father-son bonding time?"
