Hunter and Blitz were on assignment tonight in some rural warehousing area of Wisconsin on suspicion that a band of drug pushers were going around town pushing some kind of canine growth formula to enhance the performance of regional show dogs in the national dog championships throughout the country. The only reason that the two Rovers were investigating was that a number of dogs from the nationals had turned up with some kind of steroid like cocktail inside of their systems that had caused a series of muscle spasm, blindness, nausea and even paralysis in the dogs that had been hospitalized after passing out during the finals. Upon questioning their handlers and owners it seemed that many of them had been given some kind of test product to try on their canines unknowingly playing their faithful pets into the role of guinea pigs. So far there had been no fatalities but the gravity of the situation had been made clear enough so that Master had to be involved.

Blitz and Hunter were alone as Colleen, Exile and Shag were investigating another lead in the Cayman Islands where the British show dog competition was having the same problem. So far Hunter and Blitz had come up empty on several vacant buildings that were up for rent but did find a lot of dogs around that seemed to be out of place. The four guard dogs that Blitz had stumbled on were a good sign that the two were in the right general area, although Blitz was still unsure as to why the four Dobermans were chuckling as he and Hunter were told where to go next...

"Think they know something we don't?" Blitz asked with his thick German accent. The Dobbie's ears swung around as he nervously watched every corner and shadow that seemed to creep into his field vision.

"I think so. They seemed really impressed with you though especially that one female that asked for your puppies Blitz." Hunter chuckled to himself while rubbing his muzzle into his gloved paw while hiding his laughter in a cough.

"Very funny..." Blitz grunted while looking annoyed and disgusted at the same time.

"Awww, cheer up, it could be worse, she could have asked for you to try and mate with her on the spot. When she rubbed your crotch with her muzzle I think..."

"Keep it to yourself!" Blitz looked back and growled at his leader for his unwanted sense of humor. Blitz bared his menacing fangs and let them glint in the soft light of the glowing lights on the buildings.

"S-sorry. Oh well, let's look around some more and if we don't find anything we'll call back and report in." Hunter began to use his sense of smell and hearing to try and discern anything out of the ordinary. So far his keen nose and hadn't found anything accept dogs, dogs and more dogs. Thirty so far...

Twenety minutes later Hunter was almost ready to call it quits when he suddenly bumped into a wall of fur. Blinking and looking the golden retriever found himself stepping back from Blitz's backside and then shaking his head to readjust himself. Looking to his partner the team leader found Blitz staring off into space and reached up to snap his fingers in front of the Doberman's muzzle to see if he had zoned out.

"Hey, Blitz, you okay buddy?" Hunter asked while standing on side of the pinscher.

"I thought I heard something." The hackles on Blitz's neck were raised and the usually nervous Doberman seemed rather edgy.

Hunter listened out and strained the limits of his hearing before he too heard something...or rather someone inhaling. When a prick shot into the side of his neck the golden retriever jumped back and then growled before reaching up to the side of his neck. Blitz turned to look at his companion before he too felt something go into the side of his neck. It felt sharper than a pin prick but soon dulled into a steady annoyance like when one scratches himself accidently. Reaching up and pulling something from his neck Blitz looked to see a small dart glaring back at him.

Looking to his side the Doberman found Hunter curiously studying a similar dart in between his fingers before looking down at his own little nuisance. Nondescript and seemingly harmless the Doberman crushed the little thing into his leather gloved paw and watched it shatter into a dozen tiny pieces while feeling somewhat triumphant. Feeling infinitely better at his conquest Blitz opened his muzzle to say something to Hunter when he suddenly found himself feeling...funny, like he suddenly had, had too much to eat but only better. Staring down at himself Blitz noticed his body seemed to be expanding and that the ground was starting to move away.

"And yet another unexpected twist, bummer," Hunter said in his usual trademark befuddled tone as he too began to grow larger and fill the seas of his Rover clothing. The brown cargo pants that he and Blitz both wore started to creak and tear making interesting ripping sounds like you would hear on TV before he groaned and reached down to see that he was more than a little excited by the current happenings. His sheath had swollen to enormous proportions and his cock was making a circus tent out of his pants as his blood rushed down into his erection and his heart bean ten times faster to supply the necessary fluid to make such a hardon. Body aching as it blew up and out the retriever groaned and growled as he felt his inner muscles expanding and swelling as bones grew denser to handle the excess muscles filling and pumping in expansion.

To his side Blitz was having the same...problem...if you could call it that from the curious expression on the Doberman's face. Blitz's body expanded a little faster than Hunter's and his growth seemed much more exponentialas his own body seemed to be filling out in greater proportions. The girth in between his own legs thickened and came to life pushing outwards at rapid speed before finally tearing free of his leg wear and standing proudly at attention. The hard shaft was slick with fluids from his sheath and began to pulse and grow with every beat of the Doberman's heart as he watched it continuously enlarge to the point where it began to become impossible to his mind to comprehend. Eight inches...ten...thirteen....fifteen...and onwards his dogginess grew until it soon was crawling up the length of Blitz's chest without end.

Hunter's cock had done the same as he found himself looking down at the tip of his mushroomed headed phallus as his body drew outwards. Chest, arms, stomach, neck along with his legs, thighs, and feet blew into greater muscled expanse and before long Hunter could seemingly rival and tutor Mr. Universe. His body had grown so large and thick that the retriever was no longer able to even look down at his own shoes as he had pumped up so deftly with muscle. Not an inch of fat was on him anywhere as his body had grew and grew until finally the growth stopped to where it was now.

His chest had managed to stay within the bound of the green shirt he was wearing along with his arms as well but they were grotesquely gargantuan. He stood at a height of seven feet and seven inches from his previous six feet even height, his neck was twenty-two inches around, arms thirty-three inches, a chest that at forty-five inches in diameter, waist of thirty-two inches, thighs stood out at thirty-nine inches, calves thirty inches and a weight that had to have been no less than 400 good pounds of solid retriever muscle. His cock was almost a massive weapon as well standing at close to three feet and eight inches long and a foot and a half around it was big enough that a normal sized human could fit both of his arms into the enlarged slit at the height of the mushroomed head without causing discomfort. The low hanging orbs that Hunter once had had quadrupled in size to become a hefty ten pounds carrying a sloshing load of dog semen within their depths.

Hunter felt so strange and surreal at the same time as he stood there and moaned out both his astonishment and disbelief before looking over to Blitz. Where the retriever had been big Blitz looked like a titan. Muscles on muscles on muscles covered in rich brown and black fur as the Doberman stood and moaned while rubbing his enlarged cock. A foot taller now than hunter was the Doberman looked like something out of wet dreams wet dream, a neck that was twenty-four inches around, arms forty inches even, chest fifty-three, waist forty-one, thighs forty-eight, calves thirty-nine and a weight that was over 488 pounds of solid Doberman mass, Blitz had become the envy of every German war general's dream. His cock was beyond compare as it stood up in between both of his pectoral at an astounding five feet long and two feet and three inches around, his balls were the size of four ripe watermelon and weighed no less than twenty-five pounds. There was an audible slush noise when Blitz grabbed his cock was his gloved paws, the material having conformed with his growing paws to withstand the torture of being stretched so much, as h began to rub all along his length down the dark pink flesh to his caramel colored testicles.

Blitz's scent had changed along with his body to become a muskier and thicker pheromone laden mixture that made the already ecstatic Hunter breathe in deep and then reach down to rub his own erection. The three feet tube snake that was his newly grown cock was overly sensitive and immediately began to pre like a fountain as Hunter rubbed up and down the shaft with abandon. There was finesse in his pawing as the golden retriever had but one goal in mind, brining himself to the most intense climax possible. Breathing in his teammate's scent was helping as he took in great sniffs of air and soaked himself in the smell that was the masculine god like Blitz. Beside him the Doberman was coming close to his climax as his chest was getting washed with his own pre as Blitz rubbed his cock against his pecs and let the head of his dick be stimulated as much as possible. His breathes came out in harsh pants as his roving paw dance faster and faster over his five feet of maleness.

The ground beneath the two rovers began to soak with pre and drool as the two Road Rovers ministrations became faster and harder. Their hips were bounced along with their full sacs as the cum began to boil and froth over while drawing the heavy mounds upwards to their bodies. The musky scent intoxicated them making the two dogs bark and growl in tandem with each other while their tails wagged behind them like flags in a gale storm. Their gloves grew glossy and slick, their tongues dripped saliva onto the heads of their shaft and in one long, hard and intense jerk they both came together.

The resounding howls made the entire warehouse area shiver as the Road Rover's cum jettisoned out of their cocks at rapid speed and sprayed everywhere around them. The lances of white cum smacked the two males into the bottom of their muzzles and made their chins snap up before flying all around them and then spraying over their head to the sides of the buildings. When the deluge was forced to obey gravity's laws the strings of seed crashed down to the ground making deep pools of liquid musk and testosterone that caused Hunter and Blitz to orgasm even harder.

Their minds spun in a whirl as they came and came and came and came to no end it would seem. Both their testicles seemed to have an endless supply of semen until minute later the flood came to a trickle and then an all out halt. The two rovers were covered in the scent of their own sexuality as they breathed deeply and sighed once their hearts began to slow back down into a more normal pace, well as normal as they could get feeding life into every corner of the giant canine's bodies.

"T-that...w-was...in-interesting..." Hunter gasped while lifting his newly muscled arm up and stared at himself while sniffing his new and much raunchier scent. He smelled like jockstraps after a game of football and soccer mixed together and the golden retriever liked it more than anything else. He dug his nose into his pit and then sniffed as hard as he could to map out his new odor.

Blitz was meanwhile making his new triceps and quadceps flex and dance before his eyes while he held onto his new puppymaking tool with his other paw. The Doberman's eyes were shinning with new light as his ego began to whisper words of congratulations to him about his extraordinarily sexy physique. Reaching over and kissing his arm Blitz turned to say something to Hunter before his eyes glued onto his team leader. The Doberman just stared at Hunter unnoticed before he let his arm down and released his flailing cock and then stepped over to the other male.

"Blitz? What's wrong...buddy...?" Hunter said as he found himself looking at the Dobbie and then blinking...

Before long moans, barks, yips, howls, grunts and bodies began to slam into the nearby buildings as the two Road Rovers began to battle over the status of alpha male as Blitz and Hunter mounted one another and wrestled onto the ground in dominance.

Behind a nearby building a smaller humanoid shadow was busily radioing in and giving their assessment of the newest batch of hormones...

"I think you might want to tell the good doctor that he might want to do something about the side effects..."

"Well put it this way...with this brand you might want to think about talking to the adult entertainment industry about doggie porn..."

"Heheh, hey you just pay me to test the stuff...no way in hell would I try and collect a sample from them now..."

"Damn...never knew you could fuck someone like that before..."

"Huh, oh never mind...I'm coming back to base now...bye..." The person said before ending the call and flashing a few pictures with his camera phone before turning away and walking off whistling.
