„Eleven...twelve...hnnnggh!"

A metallic clang reverberated throughout the deserted hall of the gym as its only visitor placed the barbell back on its rack before sitting up with a groan, panting heavily from the exertion.

As he waited for his breathing and pulse to slow down a bit, James Mardling shot a critical glance at the now motionless piece of gym equipment, which was bending quite a bit under the - by normal standards - rather impressive weight of 650 kg.

"Not enough...", he muttered, wiping the sweat from his brow, "I know he can bench more...I've seen him do it."

Him.

James blinked the thought away, shaking his head briefly as he got up from the bench with a grunt and hoisted two more disks onto the bar, raising the total weight to 700 kg. Before returning to under the barbell he suddenly paused, taking a moment to look into one of the many mirrors that covered almost every free bit of the gym's walls. The figure that stared back at him from beyond the smooth, silver surface would have left most people in awe and even more people jealous, the figure of a German Shepherd in his absolute prime, a pair of plain gym shorts and a tank top which was several shades darker than it had been when he had entered the gym clinging to rock-hard muscles, honed to almost statuesque perfection by years of relentless training. A clean, military crew cut above a severe, but youthful, face rounded off the overall picture, giving the large canine a powerful presence that almost seemed to ooze with vigor and virility, befitting his recently acquired position as commanding officer of the most advanced special operations unit in paramilitary service, the CHIMERA.

The CHIMERA unit was the absolute elite among the armed forces of the megacorporation known as Helix Industries and the brainchild of the brilliant scientist Dr Anton Askari, consisting of several genetically enhanced, highly specialized, superhuman operatives.

And now James Mardling was supposed to lead them, which was also the reason behind him working his ass off in the company headquarters' gym way past two in the morning, seeing as sleep seemed out of the question for this particular night.

Sure, from a purely logical point of view he was definitely the most suited for the position out of all the CHIMERA operatives, despite being among the youngest. James, however, did not feel that way at all. Sure, he had also been the second in command for quite some time, although he had often felt like it was more of a token position, considering that there had never really been any need for a second in command with him around.

Him.

James felt his hackles rise slightly as he thought about the one man who was responsible for his current situation, a low growl resonating from his chest as he hoisted four more disks onto the bar.

"800 kg, let's see _him_do that.", he muttered as he laid himself down on the bench, shuffling his massive body into position under the bar, which was now bending even more.

Him.

He gripped the strained bar with two large, gloved paws and shut his eyes, which bore the ice blue iris and slitted pupils that were characteristic for the genetically enhanced members of CHIMERA - they even called them CHIMERA-eyes - trying to steel himself for the feat that laid ahead of him, although his thoughts kept wandering somewhere else.

"How dare he just up and leave like that. And how dare he'personally recommend' me as his_replacement. Wanker, as if I could just replace _him!"

Him.

He was Commander Patrick Scherer - no former Commander Patrick Scherer - the man who had led the unit for several years before , rather unexpectedly, announcing his resignation two days ago. The imposing Doberman, whose numerous battle scars told the tale of a turbulent - and violent - career in the military, special forces and freelance mercenary work before he had been chosen for the CHIMERA project, had done the unimaginable in forming their small group of "maniacs with superpowers", as he once called them, into an eight-man-army capable of winning wars. He had been a born leader, who had managed to bind the unit together not only with his natural authority, but also his experience and compassion, even having become something of an older brother figure for some of them.

But now he was gone, leaving behind some damn large shoes for the younger german shepherd to fill.

"Focus goddamnit!", James hissed, shoving the bothersome thoughts aside with quite some effort as he forced himself to concentrate on the cold metal in his paws, inhaling deeply before pressing his palms upwards against the bar.

One...two...three...

Fresh beads of sweat formed on the Shepherd's brow as he forced the tremendous weight up, his eyes staring into space.

Four...five...six...

His muzzle twisted into a grimace, showing his teeth as the tendons in his neck stood out.

Seven...

James entire body shook from the exertion, sweat now running freely from every pore. His chest felt like it was on fire. He didn't care.

Eight...

His arms locked low at his sides as the barbell came down from his eighth rep, digging into his chest just above his nipples. He clenched his teeth, forcing every ounce of will he had into his muscles.

The barbell rose, he tasted blood. He didn't care.

Nine...

The very moment the barbell began its tenth descent, James knew that he had made a mistake. His burning muscles gave, if only a little, causing the bar to waver.

"Shit!"

He fought against the inevitable with all he had, but the bar was now heading straight for his neck.

"Shit shit shit!"

He felt blood rush to his head, his own, frantic heartbeat thudding in his ears like hammer blows as the rough metal touched the fur on his throat, unfaltering in its descent as it began to crush his windpipe, slowly cutting off his air.

Little white dots began dancing before James' eyes as he began to choke, his mind reeling as he summoned the last ounce of strength, heaving with his lower back until he managed to wrest a precious inch from the bar, which was enough to allow him to fill his lungs with desperately needed air.

His victory was short-lived, however, as he felt his spent muscles lose their fight against gravity once again, causing the bar to cut off his air once more.

"So this is how it ends...what a load of bullshit.", James thought, the pressure on his windpipe having reached a point where he could feel the cartilage pop. His entire body shook in his death throes as his lungs screamed for air until finally, everything went...

Blue?

James eyes went wide as the bar suddenly became lighter and rose up, not by much, but just enough to enable him to gasp for air, which the German Shepherd did with gusto. The smell of wet, sweaty dog and raw, masculine musk hit him like a punch in the face and as he stretched his neck backwards he found himself face to face with the crotch of a very tight and very full pair of blue cycling shorts. Black and tan thighs straddled his head like two massive pillars, the short fur covering them doing nothing to obscure the hard, chiseled muscles that seemed to strain against the skin. A thin, whip-like tail stuck out of the back of the blue lycra shorts, which clung to their wearer like a second skin, revealing every detail of the wearer's anatomy with such accuracy that they might as well have been painted on.

"You got a death wish or something, kiddo?"

The deep, gravely voice of his savior snapped him out of his almost trance-like state, allowing his eyes to travel further up over the rest of its owner's body, revealing the bare upper torso of a stunningly muscled Doberman, whose large paws were now clenched around the barbell, just outside of James'.

Him.

Of course, of all the people who could come and save him from his own damned stupidity, it had to be him.

Suddenly realizing that he was still stuck for an answer, James managed to force out "No...", his voice somewhat raspy from the near-fatal contraction of his windpipe.

"Then why the hell are you down here alone in the middle of the night, tryin' to bench a goddamn compact car without a goddamn spotter? You've got responsibility now, you're supposed to be a role model, so start acting the part, understand?"

The Doberman's tone was rough and military, like that of a drill sergeant setting an insubordinate recruit straight at boot camp, and despite himself, James felt his ears flatten against his head and his tail tucking itself between his legs.

And he hated himself for it.

"S-sorry...", he rasped, "Thanks..."

"You're not done yet, Mardling.", the Doberman's tone had softened somewhat, having lost some of its reprimanding edge, "You still have one rep to go."

James eyes went wide as he stared up at Patrick's matching pair in disbelief, suddenly feeling very small, although he blamed that on the angle.

"W-what?"

"You heard me. Ten reps. You wanted to be the tough guy, so get that goddamn bar up one more time.", the Doberman's face hardened, his eyes staring directly into the younger canine's, "Don't tell me you can't do it, eh_puppy_?"

Puppy.

James clenched his teeth, his face twisted into a snarl as he felt anger rise in his chest. He hated that word, having suffered greatly under the teasing and taunting of his peers throughout most of his youth and young adulthood due to his then rather youthful appearance. The teasing had stopped when he had entered the military and packed on some serious muscle, but the word was still something of a soft spot for him.

"HrrrrrrAAAAAGH"

Searing pain raced through his arms and chest like wildfire as he threw his palms against the bar with renewed vigor, wresting inch after agonizing inch from the iron until at last, his arms were fully stretched above him.

"Good job!"

Patrick's statement was as curt as it was sincere and despite his arms feeling as if they were an inch from falling off, it put a smile on James' face as he let the bar fall backwards into its cradle.

Only to find it not moving at all.

A startled glance upwards revealed to him that the Doberman's large paws were still gripping the bar next to his own, denying its movement.

"Wha...what are you doing?"

James breath caught in his throat as he looked questioningly up at the other canine, whose hard expression remained unchanged save for a certain, predatory sparkle in his ice blue eyes that made the German Shepherd's ears flatten against his skull again.

"Teaching you a lesson.", the Doberman said calmly and suddenly, James felt the bar become heavier against his already trembling paws.

He was pushing.

That bastard was actually pushing the barbell down on him again.

"You almost killed yourself because you were so hellbent on surpassing me that you threw common sense to the wind and lost sight of your own limitations."

James was sweating profusely now, in equal parts from exertion and from fear. He tried to push back up against the crushing weight of the bar, but he had no strength left to stop its renewed, doberman-assisted descent. A pitiful whine escaped from his throat, adding insult to the injury that was bound to result from whatever the older canine was planning to do to him.

Bastard!

Patrick continued his lecture, as well as his pushing the barbell downwards, unphased by the pleading eyes of his former subordinate, though he made sure that the iron bar would come to rest on James' chest instead of his throat - after all, he didn't want to kill him.

"All you were thinking about was yourself, but that's not what being a leader is all about. It's about trying your goddamn hardest to bring out the best in every member of the team, not about your own goddamn pride! That's why a lesson is in order."

The barbell came to rest on James' chest, right across its nipples, its weight bearing down on his ribcage, the pressure not enough to break his bones, but definitely enough to allow him only shallow, unfulfilling gasps of air. His heart beat against his ribs with wild abandon, as if it was trying to lift the bar off his screaming pectoral muscles by itself.

Patrick grinned as he held the barbell in place, supporting just enough of its weight to keep it from causing permanent damage, forcing him into a slight squat over the bench, which in turn had his crotch hovering mere centimeters above James' face.

"A lesson in humility."

Bastard! That fucking scar-faced, that one-eared...

The Shepherd's mind reeled as the pressure of the barbell on his chest denied him the oxygen his body was yearning for and he felt himself getting lightheaded. What didn't help his cause was the fact that, due to his nose being all but buried underneath Patrick's crotch, what little air he had at his disposal was loaded to the point of tangibility with the raw, intoxicating smell of sweaty, musky and _incredibly_male canine. Despite himself, James could feel his body reacting to the olfactory stimulus, linking neurons that woke instincts which had been laying dormant since the times of his quadruped ancestors, but which even millennia of evolution and civilization could not completely erode.

This was a stronger alpha male asserting his dominance over a weaker male, demanding submission through his scent alone.

...that magnificent bastard.

A low growl rumbled in Patrick's chest as he felt James' damp and slightly cold nose suddenly press upwards against his perineum through the tight fabric of his shorts, right behind his balls where his scent was strongest. The Doberman's tongue darted to the corner of his mouth, quickly catching the strand of drool that had accumulated there as he watched the trapped shepherd shift subconsciously on the weight bench underneath him, spreading his muscular legs a little further in the most basic, primal display of submission, which had the side-effect of revealing a very noticeable tent in the younger canine's gym shorts. His own, already substantially tighter-fitting pair suddenly grew a lot tighter still, and his voice was husky as he uttered a single word, like one would command one's pet.

"Lick"

James was caught somewhere in between blissful agony and agonizing bliss.

The heavy bar that was digging into his battered chest muscles felt like a glowing rod of iron and was almost certain to leave a bruise, but the heavy, testosterone-laden musk that was currently superseding the air his oxygen-depraved mind yearned for as he pressed his nose into the dominant canine's lycra-covered crotch was sending his body into sexual overdrive. An inaudible moan escaped his lips as he felt his cock practically leap from his sheath, followed by a frustrated whine as it strained almost painfully against the combined force of his jockstrap and shorts.

"Lick"

The command was simple and James' body reacted almost instantaneously, needing no further explanation or impetus as he stuck out his broad, canine tongue until it rested against the smooth fabric of the Doberman's shorts, nestled right between his balls. He could hear Patrick's rhythmic panting join his own as he began licking the heavy orbs through the lycra, nudging and prodding them with the flexible muscle while occasionally moving to the base of the older canine's sheath - what little part of it he could reach from his current predicament.

Patrick's tongue flopped from the side of his mouth, twitching in the rhythm of his panting as he reveled in the sensations James' frantic licking, marveling at the younger canine's eager display. His cock was straining almost painfully against the fabric of his shorts, the snugly-fitting lycra preventing it from fully leaving its bulging sheath, and much as he enjoyed the Shepherd's current ministrations, he quickly decided that it was high time for the next part of the lesson.

James let out a groan as the crushing weight was suddenly lifted from his chest, its sudden removal also accompanied by the departure of the lycra-clad source of all-powerful canine odor from his face. The German Shepherd laid there, greedily sucking in big gulps of air as his eyes stared blankly into space for several moments after the barbell had been placed onto its rack with a resounding clang, barely noticing that his now numb paws were still grasping the rough metal. His mind was having a hard time processing just what exactly had just happened through the now slightly fading haze of lust and pheromones, but he was given hardly any respite as a strong paw suddenly yanked him upwards into a sitting position by the collar of his completely drenched tanktop, bringing him face to face with his savior and tormentor alike for the first time that night.

The Doberman's CHIMERA eyes, which completely matched his own, were hazy with lust, but unlike James', they held a dominant, almost predatory sparkle within them, which fueled the Shepherd's newly discovered submissiveness like adding gasoline to a fire, causing his ears to flatten against his skull even more.

"Stand"

Again, James' body needed no further incentive, running entirely on autopilot as he practically jumped to his feet, groaning only slightly as his battered muscles rewarded him for the sudden movement with a sharp sting of pain.

He stood perfectly still, rigid as a board save for the heaving of his chest as the Doberman drew himself up in front of him, the heat and scent radiating off his sculpted body making the Shepherd's cock strain against his jock even more, feeling the taller canine's eyes roam his body, sizing him up like a predator would his prey. Part of his mind screamed at him for submitting to the other male like this, but his body was already far beyond the point of no return.

"Strip"

Patrick felt like his cock was about to rip a hole in his shorts as James let out a barely audible whine after he had given the command, the younger canine's internal struggle almost tangible as the last bit of resistance was swept away, leaving him to act on one of the most primal instincts alone.

Submit to the superior male.

James peeled himself out of his tanktop in a matter of seconds, wincing as his abused pectorals resented their repeated use and carelessly let the drenched piece of clothing fall to the ground. His gym shorts followed suit, leaving him standing before the lusty eyes of his fellow canine in nothing but his, obscenely bulging, jockstrap. He hesitated for a moment with his paws at the waistband as his conscious mind gave a last flicker of resistance, but a husky growl from Patrick had them spring into action again in a heartbeat. Finally free from its oppressive prison, James canine length surged fully from its protective sheath like an apnea diver resurfacing for air, the red, glistening rod audibly slapping against the wet fur of his abs twice before it came to rest against the hard muscles, standing proud and bobbing in time with the Shepherd's heartbeat.

Patrick licked his chops at the sight of the younger canine's eagerness, his own member giving yet another hard throb against his shorts.

"Now undress me"

The Doberman had to force his whip-like tail to a standstill as James literally dropped to his knees before him, the Shepherd's paws darting to the waistband of his shorts and hastily pulling the skin-tight material down over his bulge, finally setting his trapped manhood free.

James' vision was hazy with arousal as he unceremoniously yanked the blue lycra shorts downwards, unable to suppress a whine as he watched with wide eyes and drool in his mouth as the Doberman's member slid from its sheath like a tapered, red anaconda. Had he not already been kneeling, his knees would probably have given out underneath him, not only due to the fact that, without the shorts, the dominant male's intoxicating scent had almost doubled in intensity.

He was also a freaking monster "down there".

Of course he was, why wouldn't he be?

The German Shepherd watched in awe as the magnificent organ in front of him twitched in time with its owner's heartbeat, sticking out from his body at an angle due to its own weight, a perfect specimen of male canine anatomy that put most porn stars to shame. A small bead of precum formed at the tip of the shaft, remaining there for a moment before it rolled down the underside until it disappeared into the short fur of the sheath which was now pulled back and bunched at the root of the organ, a small bulge indicating where the knot would form upon climax.

James realized that he was drooling, his own sizeable cock throbbing almost painfully with arousal.

"Lick"

It was the second time that particular command was uttered and just like the first time, the Shepherd's body reacted even before his mind had time to catch up. He extended his tongue and eagerly ran it along the underside of the organ before him, earning himself a spurt of pre that landed right on his nose, the potent aroma effectively cancelling out almost every other smell in the room, eliciting a loud moan from his throat.

Somewhere in the back of his mind a small part of James could not believe what he was doing, heck, until a few minutes ago he had hardly even thought of messing around with another male, but here he was, eagerly licking every inch of the Doberman's magnificent cock with wild abandon as his paws wandered to his own member, which was fully knotted and screaming for release.

"Oh no you don't!"

A wet smack resounded throughout the gym as Patrick's hefty organ slapped the submissive Shepherd squarely across the nose, ripping through the lustful haze that had clouded his vision like a crack of thunder. James looked up at the older canine with puzzled eyes, taking a moment to comprehend what had just happened before shrinking back a little upon seeing the doberman's warning snarl.

"You don't get to touch yourself unless I say so! Paws...up...here."

Each of the last three words was accentuated by another smack of the larger canine's cock on the Shepherd's nose, not as hard as the first one but still enough to make him flinch every time, never having felt more humiliated in his entire life.

And he loved it.

His paws obediently left his own cock, instead moving to rest on Patrick's massive thighs, feeling the solid muscles underneath the short fur.

"Good boy, now suck"

James had never given head before. Sure, he had been on the receiving end a couple of times with the occasional high school fling, so he technically knew what he was supposed to do, but as soon as he placed his lips around the head of Patrick's member, he realized that the gap between theory and practical experience could be very, very large and having his first dick be almost as thick as an average wrist certainly didn't help his cause.

The first few inches were manageable enough, even though the taste and scent made him light headed, though not unpleasantly so, but as soon as he reached the back of his throat, the problems began.

He gagged, then pulled back and tried again.

He choked, forcing him to pull back again.

Tears built up in the corners of his eyes as he wore himself out, whining in frustration as he failed again and again to overcome his gag reflex.

"Having some trouble there? What's the matter, too big for you, puppy?"

Puppy.

Redoubling his efforts, James attacked the oversized organ again, trying desperately to overcome his body's resistance with brute force, but to his dismay, he failed miserably, instead leaving himself in coughing mess.

"Here, let me give you a hand with that."

Strong, heavy paws reached for the Shepherd's head, gently caressing the fur on his cheeks before wandering to both his ears, softly stroking along the edges before suddenly gripping them like handlebars.

"WhaAAAhGllllk..."

James' gasp was cut short as the Doberman deftly thrust himself into his wide-open maw, simply plowing past any resistance the smaller canine's body offered with unrelenting force. Tears welled up in the shepherd's eyes as his visibly distended throat convulsed violently around the rock hard piece of flesh as it was mercilessly forced down his gullet until his nose pressed into the coarse pubic fur of the Doberman's crotch, cutting off his air almost completely.

Above him, Patrick let out a groan of pure bliss as he held James' head firmly in place, each spasm of his convulsing throat sending a jolt of exquisite pleasure through his body that caused his knot to swell slightly. He felt a rush of dominance that was downright intoxicating wash over him as the smaller canine struggled, looking up at him with pleading, watery eyes while trying in vain to pull back from the cock that was threatening to suffocate him.

Patrick began a steady rhythm of slow, shallow thrusts, never pulling back far enough for his dick to leave the Shepherd's throat as he rode the waves of pleasure for several moments until he felt himself get closer to orgasm. For a second, he considered just unloading then and there, but ultimately decided against it in favor of prolonging the experience and almost reluctantly pulled his twitching cock from the Shepherd's throat, the submissive canine collapsing to the floor in a fit of coughs and gasps.

James had never felt more violated in his entire life, but as he laid on the gym floor, a string of saliva and pre dripping from his chin as he greedily gasped for the air the Doberman's merciless cock had so long denied him between prolonged coughing episodes, his body was screaming for more, his own cock standing proud, fully knotted and leaking more pre than he could ever remember.

A strong paw gripped him by the scruff of his neck and roughly pulled him to his feet, spinning his body around until his face was mere centimeters from Patrick's, whose eyes were practically blazing with lust as they glared into his own.

"You did good, kiddo, swallowing all of that dick", the doberman cooed, his voice raspy and heavy with arousal, "I think you deserve a reward. Bend over that bench, pup."

James groaned slightly as he was shoved towards one of the gym's incline benches, almost falling over due to his legs still feeling like jelly, but he managed to grab onto both sides of the backrest.

"Hah, looks like someone's eager, ey?"

It took his foggy mind a moment to catch on, but once the reason for the Doberman's amusement became clear to him, James felt himself blush even harder, realizing that he had subconsciously flagged his tail and was presenting himself, fully and eagerly, to the dominant canine, begging to be mounted like a female ready for breeding.

"Don't worry puppy", Patrick's lips were suddenly at his ear, making him whine as he basked in the heat and scent radiating from the Doberman's body, "You'll get what's coming to ya."

A lick of the broad tongue along the edge of his sensitive ear sent a shiver through James' body and another, more desperate whine escaped his lips as he felt two heavy paws on his rumpcheeks. He knew what was coming and while part of him was terrified, trembling at the very prospect of even attempting to take that thing, another, considerably larger part was more than eager to let his alpha claim his body in every way he saw fit.

His alpha? Where had that suddenly come from? Nevermind, it sounded right.

His pulse quickened as he felt the Doberman's paws knead his firm cheeks in slow, counterrotating circles, periodically exposing his quivering pink pucker to the testosterone-laden air of the room. His entire body shivered with anticipation and fear as he felt the kneading paws stop their circling, instead pulling his cheeks apart almost gently. His breath came in quick, shallow gasps, the unbearable suspense making him whimper and whine like a bitch in heat.

Would he be able to take it?

Would he go slow?

Would he just force it in?

How much would it hurt?

Would it feel good?

James' breath caught in his throat, his mouth opening in a silent gasp as something entirely different suddenly made contact with his trembling tailstar, not hard and tapered like he had been expecting, but rather broad, flat and very wet. A loud, drawn out moan resounded throughout the gym as the shepherd rediscovered his voice, his cock spraying droplets of pre all over the bench as it slapped against his abs in reaction to the unexpected ministrations of the doberman's tongue upon his most intimate areas, feeling the broad muscle run up the crack of his quivering rump from the base of his sac to the root of his tail before Patrick let it linger over his hole, teasing the twitching ring of muscle with the very tip for several, breathless moments before gingerly applying pressure, pushing past the momentary resistance and deep into his body until it found his sweet spot hidden within.

He came.

Harder than he could ever remember coming.

James voice failed him for the second time, his would-be howl of ecstasy reduced to a drawn-out moan that never left his throat as his cock exploded, painting both himself and the bench with ropes of hot, canine seed, explosions of color dancing before his eyes.

"Mmrrrphh", Patrick huffed, continuing to vigorously probe and writhe his tongue against the shepherd's prostate, challenging the spasming muscles that gripped it in a vice-like hold, drawing out his climax to the point where he had to support the shuddering canine with both paws lest he fall over, no longer in control of his legs. He withdrew his tongue from James' warm depths with an audible slurp, eliciting one last shot of cum, accompanied by a breathless moan from the spent shepherd, continuing to support the smaller canine with both paws on his hips as he waited for him to catch his breath.

James had no sense of time as his vision slowly started to clear, his other senses following suit one after the other as the post-orgasmic haze gave way to the pleasant warmth of the afterglow. He couldn't remember anything ever having felt this good, the lewdness of the act making the insides of his ears turn red under his fur as he blushed. He had definitely not expected the doberman to do that.

"Enjoy yourself, kid?"

Patrick's voice, coming from directly next to his ear, broke the Shepherd out of his thoughts like a bucket of cold water, having forgotten about the older canine's presence entirely for a moment.

"That's good", there was a certain, slightly menacing undertone to the doberman's voice that sent a shiver down James' spine and caused his heartbeat to quicken again.

"I hope you don't think we're done already"

No. He can't be serious. He can't continue already. I can barely stand. I need more...

James let out an audible gasp as Patrick positioned himself behind his still bent-over body and leaned against his trembling form, resting the length of his rock hard member along the cleft Shepherd's rump, teasing the smaller canine with its size, a small taste of what lay ahead while he reached forward with his right paw, placing two thick fingers against his lips.

"Lick them.", he ordered, gently pressing the digits into the Shepherd's mouth, the younger canine moaning slightly as he quickly obeyed, "Be sure to get them good and wet."

James heart was beating hard against his ribs as he licked the Doberman's fingers one by one, the feeling of the hard and incredibly hot shaft that was lazily being rubbed between his cheeks, relentlessly teasing his twitching pucker making it increasingly hard to concentrate on the task at hand. His body was trembling with equal parts fear and anticipation as the fingers were withdrawn from his mouth and Patrick's teasing shaft left his rump, the prospect of the inevitable enough to make his own cock harden until it was back to full mast.

He gave a startled and to his shame, rather feminine yelp as a large paw roughly grabbed the base of his tail and yanked it upwards a little, causing him to raise his ass higher into the air, further exposing his tight tailhole, which was glistening with a mixture of the Doberman's saliva and pre.

"W-wait I-I...ah!"

James' feeble protests were nipped in the bud as the Doberman roughly pressed a slick finger into his quivering hole up to the second digit, twisting and wiggling it around for a moment before adding a second finger. The German Shepherd whined, wincing from the sensation of the rough intrusion, the thick fingers feeling so very different from the Doberman's tongue and tried to pull away until a menacing growl from the larger canine made him freeze in place.

"If you don't relax you're going to make this much harder than it needs to be, puppy. So suit yourself."

There was an impatient undertone in Patrick's voice that made James ears flatten, a whimper escaping his throat as a third finger was shoved under his tail, painfully stretching his violently twitching ring despite his best efforts to relax himself.

Patrick's cock jumped as he removed his fingers from the Shepherd's virgin tailhole, taking a second to marvel at the way it twitched at the sudden emptiness as if begging to be filled again. Lust clouded his vision as the ancient urge to mount the submissive canine, to fully claim him by filling him with his seed took over his body. He spread James' firm, muscular cheeks with both paws and spat once onto his pucker before lining up his throbbing, leaking member, reveling in the shudder his action sent through the Shepherd's body.

"You're mine!"

James' moan caught in his throat as the Doberman pushed forward hard, sinking the first few inches of his throbbing dick into his quivering tunnel, the muscles in his legs and rump bulging as he battled the resistance of the Shepherd's body. He felt like he was being split in two, his claws digging into the surface of the bench as he held on for dear life, white lights dancing across his vision as the searing hot pillar of flesh stretched further than ever before.

"Hhaaahh...too m-uch...too big...please...AAHN"

His feeble protests fell on deaf ears, instead earning him a sharp push forward from the Doberman, claws digging into his hips as the larger canine tightened his grip, feeding inch after inch of his flesh to the quivering tunnel until his hips were pressed flush with the Shepherd's ass.

Tears were glistening in the corners of James' eyes as he felt Patrick finally bottom out inside him after what felt like an eternity, feeling the coarse fur of the rim of the Doberman's sheath tickle his obscenely stretched tailstar, which sent a jolt of pain up his spine every time it twitched around the thick invader. Behind him, Patrick was panting heavily, the sensation of his entire length being stimulated by the hot, spasming tightness of the smaller canine's body nothing short of heavenly. He held himself there for several moments, allowing James to get used to his size before the urge to breed him in earnest became too much to bear. Moving his paws from the Shepherd's hips to his cheeks he pulled out about halfway before hilting himself again with a sharp jerk of his hips, eliciting a delightful moan from the submissive canine. He repeated the process several times, pulling out a little farther each time until only the tip of his cock remained inside the quivering tailhole, making every inch count as he fell into a fast, hard rhythm that caused the Shepherd's body to lurch forward every time his hips met his rump with an audible slap.

James moaned like a bitch in heat as he was fucked, each powerful thrust causing the doberman's hefty balls to slap against his own as he was impaled again and again on the larger dog's enormous dick. The pain of being spread open so wide was now accompanied by an equal amount of intense pleasure as the canine ramrod hit spots deep inside him that he never knew existed and before long he found himself getting more and more into it, pushing back into Patrick's thrusts, moaning and begging for more as his own dick, which was as hard as ever and leaking copious amounts of pre despite having experienced an intense orgasm only minutes ago, slapped against the matted fur of his abs to the pace set by their heated mating.

Patrick kept up his merciless assault on the Shepherd's behind for what seemed like ages, alternating between long, drawn-out thrusts and quick, sharp jabs of his hips that had James bite his lower lip and dig his claws into the artificial leather of the bench. Before long, both dogs' coats were glistening with sweat and the air was thick with the pungent scent of sex and musk. James could feel himself getting close to his second climax and he could tell from the additional strain put on his abused tailhole every time the Doberman hilted himself inside him that he too was in the home stretch. He could hear Patrick's panting quicken as knot grew to a size where it would not slip back into his hole despite a considerable effort on the doberman's part, making him whimper and whine as the tender ring of muscle was stretched further and further with every single, overpowering thrust, driven by the lust-crazed canine's primal urge to tie with his mate.

Grunting and snarling with frustration, Patrick leaned backwards and roughly pulled James' rump towards him in hopes of gaining more leverage through the slight change in angle. His mind was reeling, he knew that he was close, his hips moving in a blur of motion as his ever growing knot pummeled the Shepherd's entrance with the force of a jackhammer.

He wanted this, needed this.

He was going to tie with his bitch no matter what it took.

"HrrrrRRRRRRHHHHHAAAH"

Patrick's growl reverberated off the walls of the gym as he finally crushed the resistance of the smaller canine's body with one final, mighty shove, driving his orange-sized knot home with a resounding squelch.

Time seemed to slow down for James as his ring was obscenely stretched, the battered muscle clenching down hard on the much more narrow base of the doberman's cock, forcing another good inch of the throbbing pole of flesh into his body where it touched places he never thought could be touched. He felt sunbursts behind his eyes as the knot swelled yet another inch as Patrick humped him furiously with hard, shallow thrusts, dragging his entire body back and forth with every bruising jab of his hips.

James was beyond the point of being able to vocalize his pleasure, moaning, whimpering, yowling Patrick's name as every movement of the Doberman's magnificent cock within him wracked his entire body with a supernova of searing pain and delightful pleasure.

Patrick was the first to come, his howl of pleasure shaking the mirrors on the walls as he shot spurt after spurt of his seed deep into the German Shepherd's bowels, thrusting at a maddening pace while his claws dug deep enough into the brown-furred thighs to draw blood.

James followed suit, painting both the bench and his front, from his thighs up to his chin with cum for the second time before slumping forward as his arms gave out until his chest came to rest on the backrest of the shredded bench, his lower body still being held up by the dick that was firmly lodged inside his ass.

And everything faded to black.

After giving a few lazy, final thrusts as he rode the last waves of his dwindling climax, Patrick leaned forward to flatten the backrest of the weight bench James' panting body was leaning on, allowing himself to take a sitting position behind the now prone form of the shepherd, grunting slightly as the smaller canine's spent tailhole gave a twitch around his cock, causing it to add another small spurt of semen to the amount that was already churning in his insides, sealed in tightly by the size of his knot.

James felt the blunt claws of the Doberman run surprisingly gently through the fur of his back, bringing him back to reality from the trance-like, post-orgasmic state he had been in. He had no idea how long he had been out, wincing as his tailhole involuntarily twitched around the still rock hard knot buried inside, sending a dull jolt of pain through his body, which felt like it had been put through a meat grinder.

"Back with us, ey kiddo?"

Patrick's voice, which carried a certain tone of amusement, blew away the last of the haze that was clouding the shepherd's mind and with a groan he twisted his neck to look back at the big dog from his prone position.

"How...how long was I...?"

"Dunno, fifteen, twenty minutes I guess.", the Doberman said with a shrug and flexed his PC muscles, which made his cock jump inside its warm confines, eliciting a yelp from James before he added with a smirk, "I thought I'd broken ya for a moment there, but I knew you'd be able to take it."

James groaned as he tried to shift his position slightly in hopes of getting more comfortable, but ultimately gave up when all he got was another sharp sting of pain as his ass twitched around Patrick's knot again. Now that he had, at least mostly, regained his senses, the incredible feeling of fullness from what felt like liters of spunk that were trapped inside his bowels by the oversized bulb of flesh was quickly becoming more and more unpleasant, his body aching for release.

"Getting uncomfortable there, boy?", Patrick asked, having easily red the signs of the Shepherd's discomfort and was almost immediately given a nod as an answer. He began stroking his fingers through the fur on the smaller canine's back again as he continued speaking.

"Well, I'm sorry to tell ya, but after a fuck like that, my knot won't go down much for another ten, fifteen minutes, so I guess you'll have to hold on for a bit."

James let out another groan, his ears flattening against his head at the prospect, followed by a yelp as yet another twitch of his rectal muscles had him wincing in pain once more.

"Goddamnit kiddo, you're not make things any faster by jerking around like that. Just try and relax, okay?"

Nodding his head in acknowledgement, James tried his best to relax, forcing himself to breathe slowly and move as little as possible and indeed, after a minute or so, the discomfort had become a bit more bearable.

His respite did not last for long, however, and after only five more minutes he was writhing in agony again as the pressure against his sore muscles reached a point where even the slight throbbing caused by his own heartbeat was enough to send a jolt of pain through his entire body.

There was no way he could spend another ten odd minutes like this, so he turned his head around again despite the increased discomfort the renewed movement brought with it and looked back at the Doberman with pleading eyes.

"P-please...I can't take it anymore...please take it out...please..."

Patrick looked down at him with a frown on his scarred face that James found himself unable to read, but after an uncomfortable moment of silence he nodded and placed one paw on the Shepherd's right rumpcheek while the other grabbed him around the base of his tail.

"If you say so, kiddo, but I doubt you'll like this any more than waiting.", and with a slight shrug he added, "Your choice..."

He hardly gave him any time to brace himself before he tightened his grip around James' tailbase, using the appendage for leverage as he roughly pulled his hips back in an attempt to wrest his unyielding cock from its tight prison.

James cried out as he felt the gargantuan knot tugged at his abused tailhole from the inside, causing the swollen ring of flesh to distend visibly until finally yielding to the Doberman's strength on the fourth try, popping free with wet, sloppy squelch, followed by a deluge of hot semen that his beat-up tailstar was unable to contain. He groaned as he felt the thick liquid run down the cleft of his rump, coating his balls as it collected in a puddle on the synthetic leather of the weight bench between his legs, the initial torrent fading into a soft trickle that left behind a strange feeling of emptiness.

"Thank...thank you.", was all he could manage to say between deep gasps of air, his body trembling slightly as he suddenly felt very weak.

Behind him, Patrick's lips curled into a grin as he eyed up the Shepherd's abused rump, the formerly virgin pucker now looking swollen and visibly distended from his rough treatment.

"Oh, don't thank me yet...", he muttered, unable to help but lick his lips at the way it quivered and twitched, as if resenting the emptiness, begging to be filled again...

The Doberman's eyes wandered from the smaller canine's ass to his own cock, which was still standing at full mast, thick veins throbbing in time with his heartbeat along the surface of the fully inflated knot, a fresh bead of pre collecting at the tapered tip.

James pushed himself up into a sitting position with a fatigued groan, now straddling the soiled bench and he whined softly as he felt a new wave of cum pour from his tailhole due to the change in position.

"That...that was incredible...you really filled me uOOOOFFF"

He was cut off in mid-sentence as he was pushed roughly back onto the bench, the impact of his chin on the hard padding knocking the air from his lungs, making him see stars. The shepherd recovered just in time to feel both his arms being locked behind his back by one of Patrick's vise-like paws while the other roughly yanked his tail upwards, making him yelp in shock and pain. A look in the mirror ahead revealed the image of a very horny and visibly_very_ erect Doberman, his scarred face twisted into a lust-crazed, almost feral grin, drool glistening in the corners of his mouth as he lined up his still fully knotted dick with his own, trembling tailhole.

"Sorry, puppy, but I think I've changed my mind."

James screamed in terror and struggled against the larger canine's grip with all he had, but every muscle in his body felt like jelly, completely sapped of its strength by the ordeal that lay behind him and he was unable to do anything but yell even louder as the searing hot organ was brutally shoved back under his tail again, forcing out even more cum from his last fucking as he was fully knotted in a single, swift thrust that made his entire world explode in a flash of white light.

...

James awoke with a start at the feeling of a large splash of something wet and hot landing on his nose, followed by a second and a third to his chest and the underside of his chin. It took him several moments to fully realize that A, he was laying on his back in his bed, naked as the day he was born as he preferred when he was sleeping in his private apartment, B, his inability to move his arms stemmed from the fact that they were hopelessly tangled up in his blue satin sheets, and C, he had obviously just ejaculated all over himself - and not only once, judging by the already drying cum that clumped his fur together in several places.

"Aw, bollocks, again? Damn...", he muttered under his breath as he tried to get up without ruining the sheets, which he had changed only two days ago, and for similar reasons, even more than he already had.

His cock bobbed lazily in front of him as he finally stood, still hard and with a knot still much too swollen to allow the red shaft to retreat back into his sheath and stretched himself, yawning the last bit of sleep away with relish before heading to the shower.

"The same dream...", he mused as he let the warm water wash over him and reached for a bottle of shampoo, "And the same darned mess every single time..." He had woken up just like this several times over the past weeks, not every day, but at least twice a week and he could, in fact, pinpoint the exact date it had started.

Six weeks and two days ago - the day he had taken Patrick Scherer's position as commanding officer of the CHIMERAs.

"I guess there are some...issues I have to deal with if I ever want to sleep in the same sheets for more than two nights again...", he thought while he absent-mindedly massaged the shampoo into his thick fur, his fingers lingering for a moment as they brushed over his pucker, which twitched slightly under the touch.

After he had finished his shower, the German Shepherd gingerly wrapped a towel around his waist and headed for his kitchen, setting himself up a cup of coffee as his eyes fell on the phone on his counter.

James hesitated for a moment before he finally picked up the handset and dialed a number, biting his lower lip as he listened to the free line signal, waiting for the person on the other end of the line to answer.

"Scherer?"

"Hey Patrick, it's me, James."

"Now that's unexpected - how's it going, kiddo?"

"Fine, thanks. And yourself?"

"S'alright I guess. Watching the Doc's back is almost as stressful as military work, I'm telling you. So, to what circumstance do I owe the pleasure? The others giving you trouble or something?"

"Nah, it's cool, they're behaving. I actually wanted to ask whether you'd like to hook up at the gym sometime next week. You know, do some catching up - and besides, I'd like to...try something and I could really need a spotter "

"Hmm, let me see...Doc keeps me around until quite late at night, so if you don't mind that...how about this Thursday at 1100 PM?"

A sly grin spread across James' muzzle as he spoke into his phone, "That sounds just about perfect, sir."
