“Rawf!”

Starting from a sound sleep, Penny Gadget was instantly awake. After so many long years of active field duty (even if most of it was unofficial), the pigtailed teen had long ago learned the skills of how to react instantly to any crisis. Rising quickly from her bed, clad only in her panties, the trim young teen quickly scooped up her watch communicator, slipped it around her wrist, and tapped the return button.

“What’s wrong, Brain?”

The tawny-furred enhanced canine appeared immediately on the screen, his expression alarmed. Only for the briefest of instants did his large, expressive eyes waver, glancing down toward Penny’s pert breasts, before his attention snapped immediately back up to her face. He was used to it, after all: Penny had started sleeping in the buff shortly after she hit puberty, and had only started wearing panties to bed when she’d begun attending the WOMP training academy. And for all those years, Brain had been her constant companion, ever watchful, but never violating the precious trust built up between them for years.

Focusing on the emergency at hand, Brain started to make a series of barks and woofs into the communicator, adding broad gestures as well. To anyone else, this would have been nearly meaningless, with just a few scant clues from the impromptu pantomime. For Penny, however, she immediately knew what Brain meant, without even needing the translation program she’d built into the little wrist communicator.

“Somebody’s stealing secrets from the WOMP research facility?” she asked, just to confirm her understanding, her voice tense.

“Raw-raw!” affirmed Brain, always so overjoyed when somebody understood him.

“Follow after them, Brain,” Penny told her friend. “I’ll be there as soon as I can. As long as you keep with them, I can follow your collar’s tracker.”

“Rawrf!” Brain agreed, giving Penny a snappy salute before he broke the connection.

As soon as the communication ended, Penny quickly peeled down her panties, then tossed them carelessly onto the bed. Immediately after, ignoring the chill of the room, the slender teen got down on all-fours, and swiftly half-crawled beneath her bed, taking hold of a large box. It was a position in which Brain had seen Penny many, many times over the years, and had he been there to see – and especially to smell – the tender, untouched, dewy folds of Penny’s tight-clasped little cunny, thrust outward in a fashion that was almost canine, her lack of a tail leaving everything so utterly exposed, a clear canine signal that she was inviting the gold-furred dog to mount her and fill her with his puppies, he would have promptly sported an erection. An erection which he would just as promptly have ignored as best he could until it retracted, and probably hastened on its way with the application of an icepack he kept handy for the purpose.

Ever since Penny had hit puberty, she’d been unconsciously torturing Brain in so many ways. As her body started to change with the rush of hormones that brought her body to sexual maturity, her pheromones had also changed, signaling to anyone with Brain’s sense of smell that she was a young, healthy, breeding-age female. Once a month, for several days, she’d also taken on that special scent, the scent that told anyone with a nose to smell it that she was now ready to be covered by the first male able to prove his worth, and claim her as his bitch. A special scent she, unknowingly, gave off right then.

Of course, most creatures with a sense of smell that could pick up such things wouldn’t have registered them as having any particular importance when applied to Penny Gadget. She was, after all, a human. Brain, however, wasn’t just an ordinary dog, not by any stretch of the imagination. Not only had he been with Penny while she grew up, helping the canid part of his brain accept her as one of his own kind, he’d been enhanced with human genes. Along with opposable thumbs, greatly heightened intelligence, and the ability to assume an upright stance at will, as well as the addition of a magnified healing factor, this enhancement had provided Brain with two unexpected side effects, both of them closely related. One side effect was his lack of interest in other canines. Certainly, Brain had all the instinctive interest in a bitch in heat that any dog had. More than a few times, he’d battled it out on the streets against dogs much larger and stronger than himself, using his martial arts training to best effect, all to the goal of burying his bone in a nice, tight local bitch that had come into season. But dogs didn’t really understand foreplay, and though his true canine partners had enjoyed the orgasms he’d brought them with fingers and tongue and slow thrusts of his bright red cock, they didn’t really “get” why he liked to give them, and the relationships, such as they were, never lasted. Besides this, unlike a true canine, Brain was horny almost all the time, just like a human male, while canine bitches were only interested in sex when they came into heat.

Brain’s issues with mating, and his perpetual state of slow-burning lust, dovetailed into his other problem: he was more interested in human females than the females of his own kind. Actually, Brain was fascinated by humans in all senses, feeling a strange kinship and attraction to them that he’d never felt among the creatures that were supposed to be “his own kind.” Not long after Penny’s much-dreaded uncle, Inspector Gadget, had finally gotten the Internet in his home, Brain had discovered an article in a news magazine detailing the perverted horrors to be found in cyberspace, which he’d read as a part of his typical breakfast routine. Among the fairly standard mention of pornography, one particular item, listed in passing by the article’s author, immediately caught Brain’s eye, and stuck in his mind: a woman having sex with a German Shepherd.

Fascinated by the concept, Brain couldn’t help but investigate. And oh the education he’d had! Of course, Brain had never acted on the host of ideas he’d encountered out there, on the Web. After all, he was a good dog! But they’d stayed with him every time Penny had insisted he come into the bathroom with her so they could shower together, just like they’d done when she was still a full child, rather than a girl finally beginning her final, full blossoming into womanhood. She’d similarly paid him no mind as she stripped down for bed each night, not seeming to care if he saw as she bent over, wiggling her perfectly palm-sized little tushie right in his face as she shimmied out of jeans and panties alike. And just as similarly Penny hadn’t been in the least concerned about him watching her those many, many times when she’d masturbated, moaning and squealing and making such noises that no male of any species should ever have to hear and simply endure, sometimes as he lay at the foot of her bed, while she kicked off the sheets to better caress her velvet-soft lower lips, letting him look right up into her succulent little slit, or right across from him in the shower, bending over to grip the far wall with one hand, the other grinding feverishly between her legs as she trained her body to accept – and love! – the joys of sex. Penny had actually been the one who’d first discovered porn on the Internet, and though her exploration of such matters was only tentative at best, as Penny still tried desperately to be a “good girl,” despite all the strange desires that had begun to flood her young body, it was by observing her that Brain had learned that he could make his own inquiries, on his own time.

None of that mattered right then, of course. Right then, Brain was on a mission, obeying Penny like the good, dutiful dog that he was supposed to be, and Penny was getting ready to join him as fast as she could. From beneath the bed, Penny pulled out a sheer black jumpsuit, complete with a hood intended to cover the whole head, as well as gloves for her hands and booties designed to slip over any shoes worn. The material of the jumpsuit was strange, to say the least, and slightly reflective in the right light. All these qualities, however, were simply how it appeared when it wasn’t properly worn. The true value of the suit became apparent when Penny slipped it on, and stroked her hands down the length of her body, carefully aligning all the tiny lenses that lined the suit’s outer surface. As she touched herself, wherever her hands passed, she seemed to simply vanish from sight.

Originally, the bodysuit had been an invention of MAD, Dr. Claw’s organization devoted to the spread of mayhem and evil across the globe. Penny, however, had acquired one of the suits from their inventor during a mission around Africa’s diamond mines, and had since then altered the design substantially. It still made use of tiny diamond lenses, but now they were a part of the meshed weave of the fabric itself, rather than being simply attached, and hence easily knocked off with any serious blow. One disadvantage of Penny’s redesign was that the suit worked best when its wearer didn’t have anything on underneath the bodysuit, since clothes and other tell-tale bulges could easily throw off the reflective lens-cloth. Getting used to being naked, for all intents and purposes, had been Penny’s original reason for starting to sleep in the nude, back when she’d started serious work on improving the stealth suit. After she’d finished her modifications, of course, going without clothes had gotten to be a habit, so she’d never bothered going back to wearing the cumbersome nightgown that she’d used as a little girl.

Pulling the light intensifying goggles that completed the suit’s package into place, Penny checked herself over in the wall mirror. Unable to restrain a brief giggle, she posed like some of the supermodels she’d seen in magazines, or even a few she’d seen at certain sites online. Of course, she couldn’t see herself, and knew nobody else could either, so the more naughty the poses, the more of a wicked little thrill she had. Just a little thrill, though: she had a job to do, and she didn’t want to leave Brain on his own for any longer than she had to.

Slipping out through the window, Penny easily shimmied her way along the ledge to a drainpipe, and then slid to the ground. A quick glance at her watch to verify Brain’s direction, and Penny was off, taking a steady, mile-burning jog across the grounds of the WOMP training facility. When she reached the fence, it was a simple matter for Penny to climb over it, having long ago gotten used to bypassing security systems as obvious and basic as the one around the cadet base. The better protected areas were deeper into the facility, but Penny wasn’t going there: whoever had stolen WOMP’s secrets, they were already well away from the more secure parts of WOMP.

A short trek through some fields, and Penny found herself nearing the edge of the small riverside town closest to her training facility. For the most part, the town was a sleepy place, without a whole lot of excitement. What it did have, though, was a large area down by the river, where old warehouses, long out of service, now waited, abandoned. Holding up her watch once more to get her bearings, Penny’s face grew grim as she saw Brain’s signal approach one of those warehouses. Creeping around in rotten old buildings like that wasn’t Penny’s idea of a good time, but then, in her prior adventures, she’d been into plenty of worse places.

Just as Penny was lowering her watch to resume her trek to the abandoned wharfside warehouse, she paused, blinking in surprise: Brain’s signal had stopped! That could only happen if he’d removed his collar, and Brain never took off his collar.

“Brain?” Penny spoke, activating the communication feature of her watch. “Brain, come in.”

There was no answer.

“Brain!” Penny tried again, this time using a stronger signal, even knowing she risked being picked up by detection equipment by so doing. “Brain, can you hear me?”

A sinking feeling started in the pit of her stomach as Penny saw only static lines running across her watch’s screen. Brain didn’t answer. What this meant, Penny didn’t know, but she did know she’d have to find out – fast.

“If anything’s happened to Brain,” Penny murmured softly to herself as she drew close to the door at the side of the massive loading bay entrance of the warehouse, “I’ll never forgive myself.”

Then Penny went silent, all her concentration on the mission at hand. The door was locked, of course, but Penny soon passed that minor obstacle, and pushed the door open, nice and slow. Just as she thought: right inside the door were two MAD agents! The black-clad goons were sitting, looking bored, one of them reading a magazine, while the other fiddled with a portable game device.

“Hey,” said the one with the magazine, as its pages fluttered slightly, making him look up in confusion. “Did you leave the door unlocked?”

“Uh-uh,” said the game player.

“Well, it’s open,” said the one with the magazine, standing up. “Eh, whatever. I’ll shut it and then…oof!”

Penny caught the first MAD agent before he’d quite gotten his feet under him, sweeping his legs, sending him sprawling to the hard cement floor. A swift kick to the head, and he was out like a light, his grey headgear ensuring the blow, even with quite a lot of force, wouldn’t cause any permanent damage. The game player blinked, looking up from his screen, as he realized something had happened to his companion. He didn’t get to do much more than that, however, before Penny delivered two blows to pressure points, and the burly man went tumbling to the floor, lying there beside his fellow guard.

Searching the two fallen guards, Penny soon found what she wanted: a keycard, and what looked, at first glance, like a mace sprayer. Of course, since they were MAD agents, it was actually filled with stun gas, and Penny quickly gave the two guards a shot of the fast-acting, fast-dissipating aerosol.

‘That should keep them out for hours,’ Penny thought to herself, even as she made her way upstairs, toward the main office of the warehouse.

Wary and alert, Penny checked every corner, every turn, ready at all points for an attack. Despite all her precautions, however, the entire place seemed utterly, completely, eerily empty.

“Where is everyone?” Penny thought out loud. “Unless this is just a temporary outpost…”

Just like the front door, the main office’s door was also locked. Also like the front door, Penny had it open with only a minor amount of fiddling, putting her lockpicking training to good use. The office beyond was surprisingly mundane in appearance, and so was the vast, open, empty warehouse floor, visible through the plate glass window on one side. Frowning, Penny looked more closely at that warehouse floor…and then nodded.

“A false floor,” she said finally. “I’ll have to get closer to be sure, but I’m almost certain there’s more to this place underground. That’s where I’ll find the real operation, I’m sure.”

Before testing her hypothesis, however, Penny decided to take a few minutes to search the office. There wasn’t any point in backtracking, after all, if she could avoid it. Most likely the place didn’t hold any vital documents, since not even MAD agents would be stupid enough to leave the stolen files out where…

“Huh,” said Penny, blinking as she picked up a WOMP file folder. “The stolen documents.”

Glancing through the file, Penny confirmed that it was complete, with no pages missing (easily done thanks to WOMP’s standard page numbering procedure). She also confirmed, frowning in puzzlement, that the stolen file wasn’t an important document, just some old case notes, which had already been censored, rendering them useless even to the most clever of masterminds. Puzzled, Penny set the folder down, then her eyes widened as she saw what was also lying within the file cabinet she’d been rifling.

“Brain’s collar!” she gasped, picking up the high-tech comm-collar. “But why would MAD steal some unimportant documents, and then kidnap Brain?”

“Because we weren’t interested in the documents,” came a wheedling, nasal voice from somewhere nearby in the room, someone that Penny couldn’t see even as she cast her eyes around. “We were interested in who’d come looking for them!”

Too late, Penny realized where she’d heard that voice before, and why she couldn’t see its owner: it was the MAD professor, the one who’d invented the invisibility suit she’d taken and modified! He must be wearing a suit of his own! This realization, however, was cold comfort to Penny as she felt a sharp sting in one taut buttock, and looked down to see a dart protruding from her invisible flesh.

“Don’t worry, my dear,” continued the voice of the MAD professor, his freckled, plump face coming into view as he peeled off the hood of his own invisibility suit. “You’re in no danger from us. You friend, however, is a different story!”

As he said this, the professor began a high-pitched, wild cackling, even as he caught Penny before she could fall, lifting her into his surprisingly strong arms. That cackling was the last thing Penny heard, before her eyes closed, and she blacked out.

-

Beneath the abandoned warehouse, in the secret facility Penny had suspected was there, the professor continued to giggle to himself in his reedy, raspy voice as he busily adjusted the instruments on the panels before him. Of course, he already had the video feed equipment in perfect order, but the more delicate matters needed near-constant supervision.

Years ago, the professor had been one of Dr. Claw’s most trusted scientific masterminds. He’d had resources even the highest-tier universities could only dream of possessing, and played on the fringes of science’s weirdest and wildest borders. Then he’d run smack into Inspector Gadget, and suddenly he’d been carted off to an international jail. There he’d stayed, growing more bitter, more resentful, until, finally, he’d managed to break out during a shuffle of information, when the prison was converting its files from paper to digital format. Only someone of his intellectual prowess could have managed such a feat, and he’d used it as a demonstration to Dr. Claw that he was still relevant, still able to adapt to the changing times. Fortunately for him, Dr. Claw agreed: being an unemployed supervillain was the pits.

One of the first things the professor had done was investigate how he’d gotten captured in the first place. Every flaw, every nuance, every aspect of the plan and how it had been foiled occupied his attention for long weeks. In the end, he came to the same conclusion that he’d reached while in prison, even lacking the resources available to a MAD agent: Inspector Gadget was an incompetent. There was no way he could have taken down the professor’s operation on his own. This realization led the professor down a line of inquiry that few MAD agents had ever traveled before, and its conclusion was almost immediate, and yet completely irrefutable: if Inspector Gadget wasn’t the problem, then there had to be someone else causing MAD’s ploys to go awry. And if that was the case, who was it?

At first, the thought that a little girl in pigtails and her dog could have been the undoing of so many MAD plots over the years was ludicrous, preposterous, and not even worth a second glance. Had any other MAD agent been at work on the professor’s line of inquiry, then they would probably have left it there, and gone back to hunting down Inspector Gadget as the only practical lead. The professor, however, didn’t let the matter end there. Instead, he took it very seriously indeed, and went hunting through every archival file he could find. Sure enough, time after time, the girl Penny Gadget, and her dog – who, it turned out, was quite a lot more than a mere dog – kept showing up again and again. Often, they would show up in the records only when they were caught by MAD agents and imprisoned somewhere (something the professor had done himself at one point, tossing the girl, trussed and supposedly helpless, into a laser-powered diamond cutting machine, from which she’d somehow escaped before it had bisected her), but she kept appearing all the same.

Having drawn his conclusion regarding who was the real threat to MAD’s plans, the professor drew up his next conclusion shortly thereafter: Penny Gadget and Brain had to be stopped.

As he’d feared, the professor didn’t get taken very seriously when he’d presented his findings to Dr. Claw. However, he’d pressed the matter, and hadn’t given up. Eventually, Dr. Claw decided that, at the very least, endangering Penny and Brain would cause the much-hated Gadget some trauma, a sideways sort of revenge, but revenge all the same. So the professor had gotten minimal resources, and two goons to back him up. Naturally, the goons were as effective as most MAD agents in stopping Penny’s entrance to the professor’s base, and the professor had left them sleeping where they lay. But they’d served their purpose, leading Penny to think that she’d made it past the outer security, when in fact all she’d done was alert the professor to her presence by taking down the MAD agents at the front.

Everything checking out, the professor rubbed his stubby hands as he nodded in satisfaction. Good, everything was working according to plan. Soon, he’d have his revenge on Penny Gadget and Brain. Standing on a stool, the evil professor peered out through a hidden viewscreen onto the chamber where he’d imprisoned the pair, and smiled cruelly at the sight within the room. Touching a button to release a gas designed to revive the unconscious, he nodded in eager anticipation. Any moment now, the show would begin.

-

Starting awake suddenly, Penny gasped for breath as she looked around, eyes wide. A glance told her she was in an old brick room, probably a subbasement beneath the warehouse. Another glance told her she was still invisible, but her wrists were tied behind her back, and her ankles were bound together, the ropes the only part of her that she could see.

It was on the third glance that Penny saw Brain. On the opposite side of the room, her best friend was locked into place in a metal chair, metal clamps holding his wrists and ankles firmly in place, while several clear tubes led into the dog’s arms, needles penetrating his skin, many-colored fluids flowing through the tubes and into his veins. A metal bowl covered in wires and glowing lights was strapped to Brain’s head, and the dog had a dazed look on his face, as though he wasn’t quite seeing the world around him.

“Brain!” she called out to the bound dog, and he turned in her direction, his eyes sweeping the place where the invisible girl was lying, confusion obvious in his expression. “I’m wearing the invisible suit, Brain. Hurry, try to get free, and we’ll get out of here.”

As she told Brain what to do, Penny got to work doing the same, wriggling against her bonds, feeling their tightness, and knowing after a few moments of work that she could get free…eventually. Halfheartedly, as though he wasn’t quite awake, Brain tried to do the same, but within moments the headpiece he was wearing crackled with electrical impulses, and he gave up, shivering at the strange stimulation he was undergoing.

“Brain!” Penny called out again. “Don’t just sit there! We’ve got to get free!”

Suddenly, the large machine to which the wires and tubes were all attached started to gurgle, pumping a host of chemicals into Brain’s system. Almost immediately, the brown-furred dog gave a startled grunt, and then his body went tense. Even Penny was startled from her concentration on escaping, her eyes instead going to Brain as every vein in his body started to stand out. Before her eyes, the mid-sized dog started to swell all over, his body growing, expanding, his fur growing longer and more shaggy, his muscles growing rigid and defined even through his rougher fur. Even his teeth and claws started to extend, and Penny gasped in horror at the sight of Brain turning into a feral beast. He looked almost like a werewolf!

Her eyes drifting downward, Penny gasped again, this time at what she saw between Brain’s legs. Since Brain went naked save for his collar whenever he wasn’t wearing some disguise, Penny had seen him in the buff plenty of times. Right now, though, she really, finally noticed what the big dog was packing – and he was a big dog. Very big! Even as rock-hard abdominal muscles stood out from Brain’s stomach, his balls, already quite sizable, began to expand even more, as did his sheath, seeming to strain right to its limits before, suddenly, a bright red meat missile thrust its way upward, extending to full, thick erection

Crying out in words that were half-barks, half-human speech, Brain squeezed his eyes tightly shut as he went through the agony of his transformation. Soon, however, the pain faded into the background, only to be replaced by other, more pressing matters. The first of these matters was the intense strain Brain could feel between his legs, an aching need that was like the times he’d been around bitches in heat, but magnified a hundredfold. The second was the scent of a female, close by: young, healthy, and very, very ripe.

The perfect mother for his puppies. The perfect sheath for his cock.

Snarling like a wild animal, baring his long, sharp fangs, Brain strained against the clamps holding him to the chair. There was a brief sound of tearing metal, and then the clamps snapped, popping open with ease. Reaching up, Brain seized the headpiece he was wearing, and wrenched it off, heedless of the chin strap as it snapped. He’d always been strong for his size, with a wiry, lean sort of muscle that was easy to miss until he put it into action. Now, he had raw, explosive power coursing through his veins, making him the ultimate male: powerful, potent, virile, and unstoppable.

Frozen in shock as Brain tore free, Penny watched the big dog jerk out the needless still attached to his arms, tossing them carelessly aside, even as the tiny wounds they left healed over in moments. He looked like a primordial god, a muscular amalgamation of human and animal, his presence almost overwhelming for the pigtailed teen. Though she’d seldom dared to admit it to herself, Penny had long had something akin to a crush on Brain. He’d been with her through so many adventures, ever loyal, always willing to do whatever she asked. When she’d masturbated, she’d never minded him watching, never felt self-conscious in the least, though she might have with anyone else, even those few boys she liked. If anything, having Brain watching her just made her self-pleasure sessions even more intense, though of course she’d never fantasized about Brain being the one to fulfill those fantasies.

Had she?

Shoving those thoughts aside, Penny started to struggle more fervently against her bonds, desperate to get free as fast as she could. She could see the wild look in Brain’s eyes, and she knew he wasn’t in his right mind, not after whatever it was these MAD scum had done to him. There was no telling what he’d do in his current state, and Penny was determined not to find out.

At the sounds of high-pitched girlish grunting as Penny fought against the ropes holding her fast, Brain’s head turned, his nose working feverishly, his cock throbbing, precum beading at the tip at what he smelled. Those were the tantalizing pheromones of a virgin in the throes of a rich, heady heat, her body crying out desperately for a male – any male! – to satisfy the needs of her body. More than pheromones, Brain could also smell the girl’s arousal, and for a dog, smelling was as good as tasting. And Penny tasted delicious! Those pure, sweet, tight-clasped cunny lips called out to Brain, puffy and moist and inviting, and though Brain would have resisted at any other time, his instinctual side had taken over completely now, and would not be denied.

Squealing in shock, Penny squirmed and kicked frantically as she felt a massive arm wrap around her waist, lifting her into the air. Even invisible, Brain’s nose had led him straight to Penny, and soon he had her pinned beneath one arm, holding her firmly despite all her wriggling and half-hearted beating against his muscled back and tricep. Smirking at the teen’s feeble fighting, Brain reached up with his free hand, and seized firm hold of the waist of Penny’s invisibility suit. Baring his teeth, all the better to take in the rush of her sweet pheromones, Brain jerked the pants of the suit down to Penny’s knees, and instantly, as though out of thin air, the girl’s smooth, pert, pink little tushie appeared, wiggling enticingly just beneath Brain’s tightly gripping arm.

Leaning down, his tongue lolling out as he drooled copiously, Brain licked his chops at the sight – and more importantly, the scent! – of dewy teenaged folds, perfectly smooth, and already lightly flushed with arousal. Just above those innocent labia was the girl’s presented tailhole, and Brain couldn’t resist pressing his nose against that tight-clenched pucker, taking in all the sensory information that came with the territory. Everything he smelled only confirmed what he already knew, and further enflamed his desire to make this beautiful little bitch his.

If Penny had actually had a tail, she might have told Brain not to touch her by lowering it. Even in his instinctive state, Brain would have gotten the hint. Being human, and lacking a tail to lower, all the same, Penny still might have escaped Brain’s amorous attentions, despite all the years of erotic tension that had built up between them…if only she wasn’t so seriously turned on right then.

She’d never fully admitted it to herself, but Penny had a serious bondage fetish. Even when she’d been young, and didn’t really understand sex in all its many flavors, she’d actually found a strange, secret thrill every time some muscular, brutish MAD thug had captured her, then tied her up. Perhaps that was why it had happened to her so often in those days, as a sort of unconscious wish fulfillment. Now, she was once more in the clutches of a muscular, brutish male, his hot breath steaming the pearl-pink petals of her delicate sex, one mighty paw caressing her firm, bouncy little backside, while she was tied up and completely at his mercy, unable to do anything to stop him from fully satisfying his every twisted fantasy on her yielding young body.

The more Penny struggled in Brain’s grip, the wetter she got, until, soon, her juices were running down her inner thighs, only to vanish when they reached her knees, where her suit still kept the rest of her body from sight. In the dim light of the room, her exposed, visible bum was almost luminous, its delicate pink color making it clearly visible as she squirmed enticingly in his unbreakable grip.

An easy target.

Rigid enough to punch holes in reinforced concrete, Brain nevertheless didn’t just stick his prick in Penny’s pussy and start humping. Even driven wild with the strange hormones coursing through his system, the mind adjustment he’d undergone, and the overwhelming pheromones of a soaking wet teenage girl wriggling beneath his arm, Brain wasn’t the sort of male to focus only on his own needs. Dimly, he heard Penny’s voice as she was telling him…something. Probably something about how he was a bad dog (he recognized that little phrase) or that he should let her go, or how he was being controlled by an evil MAD experiment. Whatever. The words weren’t important to Brain anymore. What was very important, however, was the sound of Penny’s cute, high-pitched voice. He’d always liked listening to Penny’s voice, and he loved it even more as it rose in pitch as well as volume the moment he engulfed her outthrust cunny with his powerful paw.

Drooling over the adorable little tushie in his clutches, Brain leaned in close, all the better to hear the luscious squelching sounds of Penny’s cunny as he worked his fingers and palm into her yielding sex. Of course, with her hymen still in the way, he couldn’t push inward too much, but he’d be solving that problem in the very near future. Fingers moving a little lower down, Brain wad rewarded with a host of girlish squeals as he found Penny’s clitoris, and started to rub it at a brisk pace, until what he could see of her baby-smooth skin was bathed in a sheen of sweat, and she was trembling, cumming uncontrollably against his fingers, her bound legs kicking as she jerked through each explosive burst of pleasure that rocked her young body.

Masturbation, as Penny had discovered, was nothing compared to having someone else do it for you. She was almost incoherent by that point, her mind drifting with the pleasure burst that had shaken her to the core. Brain had made her cum…and she liked it. That was about the only thought that was able to penetrate the pink fog over Penny’s mind as Brain seated himself, resting her on her tush before him, and began to peel off her clothes, starting with her mask, revealing her naked body as he stripped her of her invisibility at the same time. Of course, with the harsh ropes in the way, Brain couldn’t completely remove the stealth suit, but he turned this limitation into an advantage – at least for him – by twisting the clothes around her ankles, pinning Penny’s legs more firmly together. For Brain, this meant Penny would be even tighter when he finally deflowered her. Dazed as she was from her recent orgasms, Penny could only watch, panting hard as she rested on her buns on her knees before Brain, her green eyes cloudy with pleasure-hazed confusion as her petite pink body was exposed.

Wasting no time, Brain caught the back of Penny’s head, and pulled her close, kissing her, his tongue easily forcing its way into her mouth. Moaning, Penny squirmed against Brain’s thick-muscled, soft-furred chest, squirming that just grew more energetic as he let his other hand stroke down her back, cupping and then squeezing her toned tushie, and then slipping into her cleft from the rear. As he began to massage her quim, Penny began to suck on Brain’s tongue, her cheeks deeply flushed, eyes heavy-lidded with the intoxicating, addictive pleasure still coursing through her body. Brain’s fingers prodded her maidenhead, and Penny’s whole body shuddered as another orgasm rocked through her, and she threw back her head, breaking their kiss to cry out in the throes of passion.

Was she willing? Was she being raped? Penny didn’t really know anymore, as Brain gripped her hair, pulling her back, making her spine arch, thrusting her plumply petite breasts forward. Now both his hands were on those lovely little mounds, squeezing them, palpating them, mauling them, then tugging on her strawberry pink nipples, before twisting them until Penny’s inner thighs quivered. The powerful alpha dog’s muzzle engulfed one of Penny’s breasts, slurping on it wetly, circling her sweet teat with his tongue until it glistened, and Penny felt her breastflesh tingling – aching, actually – with her need for his touch. Then he was doing the same to her other breast, peppering the throbbing pubescent mammary with a host of tiny nibbles that turned to suckling on each delicate mouthful, until Penny was gyrating on her knees, begging Brain, though whether to stop or to keep going, Penny couldn’t say. And when he finally bit down on her nipple, already so rigidly erect it was painful, the young blonde teen didn’t even try to restrain the scream of orgasm Brain ripped from her sweat-slick body.

Too dazed now to think, to do anything but what Brain wanted, Penny didn’t even try to resist as Brain’s hands went to her head, gripping each pigtail like a pair of handlebars. Her green eyes widened as she found herself face-to-glans with Brain’s obscenely-swollen penis, and she couldn’t help but let her mouth drop open wide in shock at the sheer size of the big dog. That was all the opening Brain needed, of course, as he popped his cock into the cute little teen’s mouth. A cruel, toothy smile spreading across his face, Brain looked down into Penny’s upturned eyes, and started to work his hips, making the poor girl whimper around her oversized mouthful as he plundered her mouth, taking his time, savoring each sensation. Almost without any voluntary action on her part, Penny was already suckling on Brain’s shaft, squeezing down on it with her mouth, just like she’d read boys liked in the books and websites she’d viewed on the subject when she’d been supposed to be studying. She felt so exposed in this position, her head held far down between her dog’s splayed legs, her perfectly smooth, almost perfectly heart-shaped bottom thrust far upward. She also felt intensely aroused.

Growling in rising pleasure as Penny proved a natural at sucking cock, seeming to enjoy the taste of Brain’s copious precum, her cheeks deeply flushed as she looked up at him with eyes that were only half open, Brain started to pick up the pace, thrusting faster, harder, making poor Penny whine all the louder at the rough treatment. Shifting his grip on her head to only one hand, Brain let the other stroke down Penny’s spine, like petting a cat, coaxing her bum a little higher, right before his powerful hand closed over one firm half-globe, then squeezed down on it tightly. Stroking across the supple twin mounds, Brain let his fingers tease against Penny’s anus, and then press into her perineum, before finding her drenched cunny once again. As soon as he found her sex, Brain started to rub against it with vigor. And the harder he rubbed, the faster Penny bobbed her head, moaning loudly around her fat, juicy mouthful of dogcock, her whole body already starting to shudder in the throes of another orgasm, just from sucking Brain off!

Feeling the itch at the base of his balls start to grow more intense, Brain jerked his hand from her sex, both hands grabbing her pigtails tightly. Using them as handlebars, making Penny whine in weak protest, Brain started to really open up, his balls slapping Penny’s chin, his knot bumping her sweet lips, before, with a feral snarl, the dominant dog started to cum, squirting his copious load right into Penny’s suckling mouth. Looking up at Brain, tears in her eyes from her gag reflex, Penny’s cheeks bulged for a moment, before she started to swallow, submissively accepting the alpha male’s gift.

Jerking his hips back, splashing a final streak of cum across Penny’s face from forehead to cheek, Brain grinned down at Penny for a moment, letting her catch her breath as she rose up onto her knees. Then he seized one slender shoulder in his massive paw, making the poor girl squeal in fright as he jerked her forward, forcing her easily back into the proper position for a submissive member of the pack: head down, bottom high, ready for use by her alpha whenever he saw fit.

“What…?” Penny started to get out, her mind only barely able to focus through the haze of forced pleasure that had settled over her brain. Whatever words she’d been about to say, however, were immediately forgotten as Brain grabbed her precious tushie in both hands, then pried her cheeks apart, his muzzle descending swiftly. Penny had only a moment to feel Brain’s hot breath steaming up her tiny quim, to fully realize what he was about to do to her, before his muzzle engulfed her sex.

Loud, liquid slurping filled the chamber as Brain greedily licked and suckled and gnawed on Penny’s smooth petals, sounds that were joined by his growls and her host of adorable girlish noises as she was thoroughly eaten out. Penny couldn’t stop herself from jerking her head this way and that, screaming again and again every time Brain’s lashing tongue or greedy maw hit her clitoris, rocking her whole world with a bright flash of pure pleasure. She was well past the point of being able to have a prayer of resisting the pleasure Brain was forcing on her. Now, Penny was nothing more than a puppet, with strings of shuddering orgasm to control her every move. Vaguely, Penny was aware that she was babbling, but what she was saying, she couldn’t begin to guess. Her smooth pink-skin glistening with a sheen of sweat, Penny’s fists clenched tightly behind her back, her toes curling in the shoes that kept them still invisible, while Brain worked his tongue as far into her as he could, only to be blocked from more than the most shallow of scooping swipes, because of Penny’s intact hymen. That didn’t stop him from pressing against that film of flesh, however, stretching it slowly inward. Each of these momentary stretchings made Penny’s whole body tense up in instinctive expectation of pain, but Brain would almost immediately turn that tension into pleasure as his tongue dipped downward again, flickering on her clitoris until Penny was panting like a bitch in heat.

In heat…Penny’s head jerked up as she felt Brain pull his head back, felt him shifting behind her, and then felt the heavy weight of his thick, pointed doggycock nudging the folds of her labia apart.

“Brain, please!” she begged as she squirmed desperately, only to have her smooth little tushie held firmly in place by the big dog’s irresistible grip. “Please, don’t do it Brain! I’m a virgin!” Her struggling grew more frantic as she felt him slot his cocktip into place, unknowingly just rubbing her cunny against his throbbing erection, arousing the powerful male even more. Sensing her plea wasn’t working, feeling Brain’s cock starting to nudge even more firmly inside of her, her maidenhead stretching a little more with each movement, Penny raised her voice again, more high-pitched and desperate than before. “Brain, stop! I haven’t had my period this month! You…you can get me pregnant!”

Looking back, her green eyes wide and pleading as she shook her head to add emphasis to her words, Penny saw Brain’s toothy grin, saw him nod his head to counter her shaking. His belly tensed, and so did his rump as he pulled back, and for just a moment, Penny relaxed, thinking that perhaps…just perhaps…

THRUST!

“AAIIIEEEE!” wailed poor little Penny as her cherry was popped by Brain’s first irresistible thrust. Most of her reaction came from the shock of being penetrated for the first time, rather than the pain of being deflowered. Thanks to her active lifestyle, and constant adventures, Penny’s hymen was quite thin, and Brain had made sure she was very well-lubricated before he’d crammed that oversized prick of his into her undersized pussy. All the same, it was a very tight fit, and Penny was being stretched far more than her body had really been intended to take.

As for Brain, he was in heaven! His hands mauled Penny’s tiny pink bum as he sank himself right up to the knot, growling as he felt her inner walls rippling around the immense intruder he’d squeezed into her. For a moment, Brain paused, just savoring the sensation of being balls-deep in a freshly-deflowered human teen, giving Penny’s body a chance to adjust to the big dog’s more than significant size. Then he started to grind his hips, making Penny wail loudly as he churned his shaft inside of her, stimulating so many sensitive places the poor girl had never dreamed might exist, not in all her wildest erotic fantasies. And just like that, Penny was cumming again, screaming again at the top of her lungs as orgasm came crashing down on her with all the force of a tsunami.

Giving a sharp bark as Penny clenched and flexed around his rigid erection, Brain’s tail hiked up as he pulled his hips back, then jerked downward as he thrust into Penny again, giving her poor little tushie a hard slap with one strong hand, just an instant before his balls slapped her inner thighs, his hips slapping her tender pink bottom. Hunching over her, Brain growled right in the little teen’s ear as he started working his hips, licking the sleek muscle visible through her smooth, healthy skin all along her trim back as he shafted the tight cutie before him. The room filled with the sounds of Brain’s hips smacking Penny’s butt, and soon her buns were turning a bright red, as was her overstretched quim as blood rushed to her sex, flushing her genitals, making them just that much more sensitive.

Breasts bouncing, and her bottom as well, Penny was babbling again, pleading with Brain to stop, to spare her, not to make her his slave, his bitch, his plaything, not to put his puppies in her. But the more Penny pleaded, the more violent Brain’s thrusting got, until soon his hips were a blur, filling Penny’s ears with the luscious, wet slurping of his cock pumping like a steam piston right up to the gates of her defenseless womb. She could feel the numerous spurts of Brain’s precum splash right against her cervix, and every time that happened, her inner walls contracted violently, as though greedy for Brain’s cum, and the copious sperm it would carry, all the way up to Penny’s fertile egg.

That thought was the last straw for Penny, and her high-pitched wail rose to an earsplitting crescendo as Brain’s knot popped inside, her cunny clamping down immediately behind the throbbing ball of hard flesh as Brain gave a sharp bark of pleasure, feeling the pointed head of his shaft just barely penetrate Penny’s cervix. Now there was nothing between her ripe little womb and his healthy, virile sperm. This was Brain’s last thought before his balls started to tighten, and he felt himself riding right over the precipice of pleasure.

“Not inside!” Penny was babbling, almost incoherent from her multiple orgasms. “Pull out! Please, pull out, before…before…ah! AH! AAAHHH!”

Penny’s cry of orgasm made her tense pink rosebud flutter as Brain looked down, admiring how widely he was stretching her. Even if he’d wanted to, the big dog couldn’t have pulled out, not with his knot firmly in place in a cunny as tight as Penny’s. And then Brain’s brain was afire with the sizzling sparks of inferno pleasure, a blaze that reached its height as his whole body shuddered, every muscle tense, standing out clearly through his soft brown fur, before his cock twitched one last time, then began to gush cum into Penny’s receptive young body. Whereas most doggy cum was weak and watery, relying on quantity rather than quality, Brain’s was thick and gooey, as Penny herself had discovered while drinking it down. Enhanced as he was, even his sperm was improved, better than the sum of his parts, human and canine alike. And there was a lot of it, every last little sperm cell beating their tails with frantic energy, desperate to be the first to fertilize the egg towards which they swam with unerring precision.

In a matter of minutes, even as Brain was still humping her, making her heart-shaped buns glow Valentine red with repeated impacts, Penny felt the fastest, most fit of all his sperm penetrate her waiting egg. No, not just one: her poor little egg was being gang-banged! She felt it! And with that multiple penetration, Penny couldn’t hold back her final high-pitched wail as pleasure finally overloaded her mind and body, her head lifting as her back arched, plump young breasts outthrust, tender pink nipples perked to painful hardness, before Brain’s strong hands engulfed them from behind, pulling her back into his rapidfire thrusts, giving her no escape from the pulsing pleasure that coursed through every fiber of her being.

Overstimulated, Penny’s eyes grew heavy-lidded, her mouth dropping open as she went limp in Brain’s hands, even as her taut-muscled tummy and firm young tushie continued to tense and flex with each burst of pleasure that continued to shake through her. Feeling her slump in his grasp, Brain slowly let Penny sink forward, grinning a little at her sharp whimper as he popped his slowly-deflated knot free, his shaft glistening and slick with her juices. Squeezing Penny’s upturned bottom in his strong hands, Brain admired his handiwork, while a thin trickle of cum dripped slowly from the girl’s gaping, thoroughly bred quim.

Dropping his eyes to look at his still-rigid erection, and then lifting them to Penny’s snug pink anus, Brain licked his chops, nodding to himself as he came to a decision. Penny’s head raised slightly, and she gave a confused moan as she felt Brain’s powerful paws spreading her tender buns, before her eyes snapped open as she felt the pointed tip of his prick prodding her backside, slicking it up with his still-dripping precum.

“No, please!” she pleaded, her impending sodomy helping her regain her lost energy. “Not like that! Not there!” The pressure started to build, and she knew her feeble struggles, her strength already screwed right out of her, had no hope of stopping Brain from doing with her as he pleased. “Wasn’t my poor vagina enough for you? Wasn’t it enough to get me pregnant?! No…no…oh!...Oh!...OOOOOH!”

Brain grunted, his jaws grit tight, as his penis popped past the girl’s tight-muscled ring. And he’d thought her pussy was tight! Fingers pinching Penny’s nipples, tugging on them as though he were milking them, Brain began almost immediately to hump Penny’s butt with all his might, pounding her sweet little buns right into the floor!

Maybe it was the sounds of flesh thudding against flesh. Maybe it was the sound of Brain’s feral growling in her ear. Maybe it was because she was already hyper-sensitized right then, her body primed and ready for experiencing the ultimate heights of pleasure, thanks to Brain’s prior foreplay. Maybe she’d been injected with something as well by the MAD professor who’d captured them both. Whatever the reason, as soon as Brain’s heavy balls slapped against her dripping quim, Penny came. Hard! Her head snapped back, her eyes and mouth popping wide open as she clamped down tight on Brain’s pistoning shaft, forcing him to work for every thrust, making hum grunt even more loudly.

Then Penny started to cry out, ready to scream with all her might. Before she had a chance, however, Brain turned his head slightly, and covered her mouth with his muzzle, kissing her. Looking up, Penny saw the light of feral breeding madness leaving Brain’s soft brown eyes, saw his old self returning. She also saw his guilt and fear as the full realization of what he’d done to her came crashing in. He was the one to whimper, then, his eyes begging with Penny for forgiveness. Forgiveness was easy, and Penny granted it willingly, kissing him back with all the enthusiasm in her young body. That was the last straw for Brain, and he whimpered again, this time in pleasure, as his cock started to pulse once more, and Penny felt his thick, hot cum splashing against the inside of her rump.

In his monitoring booth, the professor lay slumped back in his chair, only barely conscious, his limp cock dangling. He’d cum more times watching Penny and Brain than he’d ever done in his entire life! Now the short, middle-aged man was completely spent, and utterly exhausted. He was also completely unaware of the splatter of cum that was even then trickling down onto the delicate equipment of the panel before him, and didn’t even register when a particularly important part of the panel sparked briefly, then gave off a puff of smoke as it shorted out.

Penny and Brain, however, noticed. Together, they’d been exploring the walls of the blank room, and soon found the hidden exit. Just as they’d been working to crack the magnetic keycode that held it shut, the door suddenly unlocked, as power was interrupted. Working together, the pair yanked the door open, and raced out into the hall, heading straight for the main control room.

Everything after that was denouement. The professor was easily found, and just as easily captured, as Penny was a far better combatant than she’d been when they’d first met, back when she was a little girl, and he wasn’t terribly effective as a fighter when facing a trained WOMP agent on equal terms. He and his goons were soon being arrested, and carted off to an international prison, there to be interrogated until they revealed everything they knew about MAD and its activities. Certain sensitive documents were found on the premises of the base, providing vital information to WOMP, which would lead to trouble for MAD for years to come. All in all, a successful mission, despite its setbacks.

On one front, however, the professor’s efforts were at least somewhat successful: he’d managed to cause Penny to take a break from fighting MAD’s efforts across the globe. Specifically, he’d caused her to take a break of about six months – roughly halfway between the time of human gestation, and canine. That was how long it took for Penny’s pregnancy to progress.

Gripping Brain’s hand tightly, Penny gasped in her room as she felt yet another contraction. The feeling was more intense than anything she’d experienced up to that point, and that included all the times she and Brain had made love over the past several months. After their rough start, the two were indeed a couple, though they’d kept it more-or-less a secret, save from Penny’s closest friends, Kayla and Atsuko, and from her gynecologist.

Penny’s gynecologist was the one who’d given her the little disks presently taped to either side of the teen’s forehead. They were pain dampeners, one of the latest of WOMP’s many technological innovations for their agents. What this meant for Penny, as she arched her hips as much as the pressure of her plump belly would allow, was that she wasn’t feeling any pain…but she was feeling a lot of other things!

“I can’t even start to describe it, Brain,” she got out, her voice tense, eyes squeezed tightly shut. “It’s…it’s like having you mating with me, but from the inside, and like there was more than one of you. There’s just so much…”

And then Penny’s words were cut off, as the puppies started to come. Unlike a human birth, the process of giving birth to enhanced canines was faster, and much less traumatic, even pleasurable, but it was also exhausting. Fortunately for Penny, Brain was there to wash off each of their three puppies, one by one as they came out, dry them with a towel, and place them in Penny’s arms. At the end, Penny was worn out, but she was happy.

“Look,” she said, smiling down at the tiny, furry bundles in her arms. “That one has fur the color of my hair. And that one has your nose, Brain.” She giggled, and kissed the nose in question. “They’re so beautiful.”

Though he didn’t say much, Brain had to agree. And he also felt that his mate, Penny, was the most beautiful of all.
