The Right Incentives

Diz always liked dogs, some a lot more than certain people he could think of. He considered himself lucky in his job as a dog walker, and not only because he not only spent five days a week surrounded by the most friendly and loyal bunch of dogs a guy could ask for. That was certainly a big part of it, but there was also the huge bonus that considering he spent most of that time walking to and from various dog parks in his local area, most of the other humans he encountered were equally dog crazy.

Except today, the dog park seemed oddly empty. Devoid of both dogs and owners despite the beautiful spring weather, leaving Diz and the female border collie that he was walking feeling a little exposed. Normally by now Layla would have been dashing all over the park, and Diz following as quick as he could behind her in order to join in whatever game she decided she wished to play either with him or some of the other dogs. Today though the collie stayed close to her walker's heel despite his having removed her leash several minutes ago. They both padded quietly along the park's central path, and just as often as the human male found himself looking down at his collie charge, he found her looking up at him with curiosity and concern.

It was almost a relief to realise that neither Diz nor the dog he was looking after were going crazy with paranoia, when suddenly a flash of dazzling light surrounded them both and the rest of the world seemed to vanish into instant and complete darkness. A loud yelp escaped the human male's canine companion, and he groaned as without any apparent reason he suddenly found himself feeling woozy and disoriented. He stumbled, and let go of the collie's leash. Rather than running though the dog pressed fearfully against him as Diz fell to his knees, and the last thing he was aware of before unconsciousness stole over him was the feeling of a warm, wet tongue lapping at his face, wordlessly begging him to be okay.

"G-good girl..."

Those words escaped Diz not as he lost consciousness, but as he woke up. The last thought he'd had before slipping away from the waking world was still tingling upon his lips, and he spoke it before he could realise that there was no sense in doing so. No longer could Diz feel the border collie's tongue on his face, or anywhere close by him. In fact, he couldn't see her, or anything in the pitch blackness surrounding him.

The darkness didn't last though. Whether due to hearing his words, or recognising his wakefulness some other way, a light sprang into being somewhere above where Diz was lying. He gasped and tried to shield his eyes from the dazzling glow, and grunted as he found that his arms were restrained. Wincing in the continued glare of the painfully bright white light, Diz looked from side to side, and saw that his wrists and elbows were secured to what looked like a metal surface by heavy, silvery metal manacles. He tried to shift his legs, looking down the length of his body with a groan of dismay as he realised they too were bound. And it was then, as he looked down himself, that he realised something even more disturbing. Wherever he was, wherever this place was, he wasn't just bound spread-eagled to a flat metal table. He was bound spread-eagled to a flat metal table, absolutely stark naked.

Somewhere close by, Diz heard the soft whirring of machinery. Immediately he turned his head towards it, peering through the darkness beyond the spotlight trained upon his bare body and yelling in frustration.

"H-hey! Hey, what the hell is this?! What are you doing? Who the fu-..."

His voice trailed off again with a groan as the whirring grew louder, and swinging down from the darkness above he saw a robotic arm. The jointed length was the same marking-less silvery metal as the table to which he was bound, and though Diz was no expert in robotics he could tell from the fluidity of its movement, the joints able to spin and pivot through a wide range of angles, that the mechanics of this device were not something made from a DIY kit. This was the sort of machinery built by someone with resources. Someone organised. The question was, should that fact have made him less terrified, or far more so?

Before Diz could make a decision either way, he noticed what the robotic arm had clutched in its mechanical grip. At first it looked like just a ball of cloth, but as it swung down over his naked body, he could see that a small nozzle at the end of the arm was dripping fluid out onto the cloth, which was already soaked through presumably with the same substance. The human drew in a sharp breath, determined not to inhale what for all he knew could be chloroform or some other substance meant to knock him out again. He struggled helplessly in his bondage as the metal arm moved the sodden cloth towards his face, dripping heavy droplets of whatever mysterious substance it was saturated with down onto his bare stomach and chest.

Within the next ten seconds, Diz gave a mournful, muffled groan as he felt the bunched up rag being pushed against his face by the deftly accurate mechanical arm, held directly under his nose and over his mouth. There was no way he could draw breath without inhaling it, and even if he didn't, already droplets of the liquid substance were dripping onto his dry lips, threatening to slip into his mouth and onto his tongue if he was even tempted to draw the tiniest of breaths or make the smallest of any more vocalisations.

Knowing that it was either breathe now and face up to what he had coming, or breathe when he had no alternative and face the exact same consequence anyway, Diz shuddered with worry, squeezed his eyes tightly shut, and sucked in a lungful of air through his flaring nostrils. Almost immediately his eyes sprang wide open once more. Goose-flesh prickled over his bare body, and a few seconds later he let loose that first gulp of air in a heavy, heated groan of shock. It wasn't chloroform. It wasn't any kind of drug, at least nothing that Diz recognised as one. He did know that smell though. That scent. As a dog walker and dog sitter he'd encountered it numerous times. It was the scent of a bitch in heat.

"W-what the hell is this, some sort of sick joke? You think because I look after dogs, I'm gonna get turned on by them?"

No response. No sign that anyone anywhere heard him, other than the whirring of yet another motor. The arm holding the pheromone laced rag to his face did not move, but out of the corner of one eye Diz saw another arm approaching him from the side. He cried out as he saw the glinting of a needle at its tip, but with his arms and legs bound there was nothing he could do to escape or avoid the incoming injection.

"A-ahh!"

He cried out in shock more than pain as the needle pierced his skin and he felt the prickling of foreign fluid being injected into him. The human male drew a sharp breath in as the needle withdrew, and it was then, almost instantly, he realised the purpose of the injection and heat-scented rag combined. This time as Diz breathed in, there was more than a familiarity to the strong scent of canine pheromones. He inhaled them, and found himself almost relishing the overpoweringly strong odour. His eyes bulged an he inhaled again, a deep, gulping gasp not for air, but for more of the scent. Already his heart had been racing with fear, but now it pounded and thundered for a whole new reason. Excitement. The thrill of the scent causing his hair to stand up on end across his pale skinned body, and his cock, flaccid and rather embarrassingly shrivelled with fright, to twitch and begin almost immediately to swell with desire.

Whatever was in that injection, it acted fast. It took less than thirty seconds from the moment the needle pierced Diz's skin to the moment he watched his cock rising to full arousal as he craned his neck upward, trying to rub his face and nose up against the dripping, heat-scent soaked rag. He stared down at his erection as it grew, watching his hips buck up from the metal table and gasping with delight as he watched droplets of pre-cum forming at its tip, before beginning to drool down its length in thin but passionate rivulets. All that desire however, all those feelings were nothing compared to how incredible a sensation surged through the male when he felt a few droplets from the scented cloth drip down into his now open muzzle, and onto his eager, waiting tongue.

"Please! O-oh. Oh... please!"

His hips began to twitch and hump at the air even more desperately as his mind blazed with fiery cravings. His eyes were glazed with passion as they stared, unblinking up into the dazzling white light above him, and his whole body felt like it was tingling in anticipation of... of something. Something big, something intense, and something wonderful that was soon to happen whether he liked it or not.

A strangled cry, almost a yelp of delight, escaped Diz when he heard yet more whirring from the darkness around him, and saw not one but two new mechanical arms moving towards where he lay. One approached from above, a similar direction from which the arm that was now holding the scented rag to his face had come. Upon its tip however was a far larger apparatus, not an arm for gripping, but a cylindrical tube with clear sides and some form of padded opening at its exposed end. The other approached from the opposite side to the one that had carried the needle, but it could well have been the very same arm, and possessed the same attachment. This time Diz didn't even think about struggling, and actively craned his neck to one side in order to present his flesh to the approaching mechanically operated syringe.

The two arms made contact with the male's body almost simultaneously. Diz strained and groaned through the rag pressed to his face as he felt yet another syringe full of god only knew what being poured into his bloodstream, the slight pain of its piercing his flesh only serving to enhance the pleasure as the transparent tube lowered itself down over the straining, dripping length of his cock. A soft hissing sound escaped the robotic arm between Diz's legs as the needle withdrew once more and vanished away back into the darkness, leaving the man to watch, transfixed with anticipation and shaking more violently than ever in his bondage, as the padding at the base of the tube and now wrapped around the base of his cock was inflated with air, locking itself tightly yet tenderly around the lowermost flesh where his rigid shaft met with his crotch and the upper edge of his balls.

"O-ohhh..."

Another hissing started up almost as soon as the first had ceased, and Diz's already wide eyes bulged as he felt the air being sucked out of the tube in which his cock was now embraced. The pressure built rapidly over just a couple of seconds, causing Diz's hips to rise up and his mouth to fall wide open in an 'O' of pleasure, before a small valve at the upper edge of the tube sprang briefly open, and Diz groaned as the pressure was released. It closed again, and with another hiss the pressure began to build once more. The feeling was incredible. Like he was being squeezed by the vacuum around him, only the air filled material at the base of the shaft doing any physical caressing of his length. Not like any oral, handjob or otherwise intimate stimulation the male had ever known before, but undeniably pleasuring and rubbing his cock with mechanical efficiency, as though seeking to milk him for what his manhood had to offer.

Before Diz could become too lost in the sensation of having his cock suckled by the mechanical marvel currently at work around its length, the light shining down upon him from above abruptly ceased, plunging him into total darkness. He cried out in shock, but pleasure too as the mechanical apparatus working him so pleasantly continued uninterrupted, only to let slip a longer, louder cry as in place of the bright spotlight the space above him was lit up to reveal itself as what seemed to be a whole collection of large, flat screens. He saw pictures of humans. Naked humans, standing beside obviously naked dogs. Men and women, nude but unaroused and unsexualised, photographed standing, sitting, some even holding normal dogs in their arms. These pictures flashed in front of the male's eyes for maybe twenty seconds, then were replaced by a far more fascinating, intoxicating and arousing set of photographs.

"A-ahh... t-that's... ohh god..."

Diz barely had time to realise that he wasn't looking at some artistic rendering, a hyper detailed CGI design of what looked like a dog with a humanoid body, before he felt the tingling across his body's skin intensifying and glanced down just in time to see fine black and white hairs springing up through the pores of his pale flesh. He cried out in surprise and concern, but after just a few seconds realised there was no pain associated with this seemingly impossible sight, and no feeling of feverishness to explain this as some possible hallucination, unless of course you considered the heat and excitement of the milker masturbating his twitching shaft.

The male stared at his body as he watched himself change, fur getting thicker and spreading ever faster as it grew over what felt like every inch of him other than the straining length of his erection. It was only when he threw his head back to whimper in pleasure and confusion that he saw the image of the surprisingly realistic dog person had been joined by many others. Pictures of these two legged canines not just standing innocently as the humans had been, but in all manner of poses and situations. Many of the males were aroused, and looking at the females... the women, they looked as though they were, too. Soon those pictures also vanished, only to be replaced by even more intimate and personal images. Pictures of other figures, dog-like but humanoid, on tables just like him. Men of all shapes, all breeds, with straining cocks and desperate looks on their eager faces. Women open mouthed, tongues lolling out, panting but not because of temperature.

They were all being pleasured. The men and the women alike. Milked by devices like the one suckling on Diz, or fucked by piston mounted dildos in the case of the women.

Another flash of the screens, and the images were replaced by moving video. No sound accompanied them, none was required given the continued heat-scent flooding Diz's nose and mouth, but the sight alone was enough to drive the male wild as he felt the bones in his toes and fingers crunching and crackling as they shifted in form and function, growing less and less like a fur clad human, and more like the figures in the videos he was now watching. Some writhing and straining upon metal tables like him. Others alone in metal walled cells, desperately humping at their own hands. Or in a few cases, together.

"Please. Please... y-yes..."

Diz watched, transfixed, as these dog and human hybrids copulated feverishly with one another. He watched thick, red, canine knots driving themselves into swollen and dripping women's depths, and saw the owners of those respective organs thrashing and shuddering and howling in silent but obvious bliss.

"Yes!"

The male yelped once more, that cry of joy and pleasure becoming a strangled and lingering howl as his parted lips suddenly burst outward his now fur covered flesh stretching and re-moulding itself over the bone beneath as his mouth became a panting, toothy muzzle with a black button nose. Atop his head Diz could feel his ears seeming almost to float upward, and at the base of his spine the changing, pleasure stricken male could feel an intense but not unpleasant pressure building, trembling with excitement as suspicions of what that might be began to rush through his pleasure-ridden mind.

It was strange, but of all the parts of Diz that were changing perhaps the one area he paid the least attention to was his own erect cock. He was vaguely aware that within the milker his shaft was swelling slightly, that its tip was growing more pointed and the fleshy surface of the shaft was glowing a deeper and more passionate shade of red. But somehow the fact that his cock was becoming more dog-like in itself didn't matter nearly as much to Diz, perhaps because unlike the new rush of sensations coming from much of the rest of his shifting and transforming body, his erection felt just as good as ever as it was squeezed and milked by the device wrapped around it.

What Diz did take more care to notice was the evolution of his new body bringing about a whole new raft of sensory experiences other than simple physical pleasure. As his olfactory senses caught up with the development of his new muzzle and canine nose, the male reeled as his mind started to acknowledge the canine pheromones he was inhaling on an entirely different plain than before. Since the very first injection he had been unable to help but react to the arousal-provoking chemical cocktail being wafted in front of his nose, but now it felt like he truly understood what those scents were trying to tell him. It wasn't just a call for sex, it was like a chemical fingerprint, unique and provoking not just a crazed desire for women... but for the one woman who had produced it.

The trembling, moaning, increasingly collie-like male grunted and gasped as he thought about the woman responsible, and how whoever was holding him here had gotten such a substantial volume of lustful fluids from her. His eyes rolled back into his head with bliss at the mere thought of her being bound and pleasured just like him. He howled as he felt his knot beginning to swell, pushing out against the inflated ring holding his cock tightly within the milking machine bringing him such overwhelming stimulation. Suddenly all he could think of was this beautiful creature who craved a man, a dog just like him so intensely that she was pouring out such volumes of pheromones just to try and get his attention. All he wanted to do was breed her. Fill her. Lock himself within her until he was sure that his puppies were going to be growing in her belly.

"Yes! Yes!"

The combination of the intense suction milking Diz's cock finally became too much when combined with these vivid fantasies and the added sensation of his thick knot straining against the inflated band gripping at it tightly. Diz stared down the length of his body, and yelped in joyous pleasure as he watched his cock beginning to strain and twitch, ribbons of cum being launched out into the see-through chamber surrounding his erection only to be slurped loudly up by the motor causing the suction. The more he came, the more intense the suckling of the vacuum felt upon his throbbing member. His hips jerked feverishly, and Diz howled in bliss as his whole midsection began to prickle with the same intense heat that had overcome him before his fur started to sprout.

"Oh god. O-ohhh fuck!"

In a split-second, without any warning whatsoever, that pleasure surged to a new and violent intensity. Diz arched his back, his toes and fingers splayed and trembled violently, and a frantic bark of shock and euphoria erupted from his muzzle as he felt something bursting out of the base of his spine, a tail growing bone, muscle, flesh and fur in a matter of moments within the savage fury of his climax.

It was only as Diz's orgasm came to a close and a little sanity returned to his no longer quite so pleasure addled mind that he realised his transformation was complete. At least, if this was the form he had been intended to inhabit, if whoever had done this to him wanted him to be the same manner of dog and human hybrid he had seen flashed up on the screens above him, they seemed to have achieved that goal. And now, perhaps more importantly or perhaps just as a bonus, they not only had a new dog... but a nice sample of his first load of seed as such a creature, too. Maybe now they would change him back. Or let him go. Or at the very least, let him up from this metal table.

"A-ahh..."

Diz shuddered and yipped softly, blushing and squirming as best he could as he realised something. The milking machine hadn't stopped. Hadn't deactivated. It was still suckling on his cock, still squeezing his knot. He was so sensitive now, but the mechanical milker didn't seem to care in the slightest.

"Hey. H-hey... I've cum. I've already cum. Please. Ahh... it's... it's too much. You... a-ahhhh..."

It was difficult enough to convince himself of what he was yelling given the heat-soaked rag still dripping over his muzzle, but when Diz heard the distant hum and whine of yet another motor, he sighed in relief, assuming that the milker's mechanical arm was about to withdraw. Instead, he groaned and whimpered as from out of the darkness a new arm descended. This one didn't have a milker attached to it, but instead what looked like two small nubs of metal about an inch long protruding from a yellow and black striped box. There was a symbol on the box too, but from its current angle the collie couldn't quite make it out.

It was only as the arm descended between his legs, and its tip swung forward, positioning itself below the still active milker and with those two nubs pressing ever so gently against Diz's plump and white furred balls, that the male was able to catch a glimpse of the symbol as he peered around his still stiff, twitching cock within the milker's grasp. His eyes widened, and he yelped sharply.

"Hey! C-c'mon. Please. Please, y-you... oh god... you're not? Please, you can keep going. You can keep milking me. Just please, y-you don't need to... oh... oh god. Ahhhhhhhhh!"

A small hum began to ring out from the black and yellow box as Diz spoke. It got louder and louder, like a charge building towards something. And that, combined with the lightning bolt inscribed on the box's side, told the collie exactly what he needed to know a moment before a small but intense electric discharge burst from those metal nubs, directly into the collie's exposed and already overworked testicles.

"_Aaahhhhhnnoooooohhh fuuuuuuucck _!"

For a few seconds, Diz howled and wailed in misery as the most intense pain he had ever known coursed through him. And then, abruptly, though the crackling electricity continued to pour out of the device at that same low but devastating level, he stopped. He stopped as he ran out of breath, as his eyes bulged, and as he stared down at his cock twitching and throbbing within the milker.

Quietly, subdued with shock and wondrous dismay, Diz gasped.

"Ohh... oh god..."

He sucked in a deep lungful of air, shuddered, and readied himself to begin howling all over again as he watched his cock strain desperately within the suckling vacuum chamber. Before he could vocalise a single note of his amazement though, it began. What he had suddenly felt building inside him. What seemed to have sprung out of nowhere, not just joining the pain of the electric stimulation, but overriding and co-opting the pain into pure, unfathomably intense renewed bliss.

Diz howled. He barked. He wailed in pleasure as for the second time in less than two minutes, he began to climax, and to provide his unknown captors with yet more of his transformed body's unique and valuable cum.

"Ohhhgoooooodddd_yessssss_!"

The second load. The second sample. The second, but but far from the last his new and virile body was capable of producing, if only the right incentives were offered.
