Part 7


Being led around the school corridors on all-fours, wearing nothing but a shirt and every single person wanting to stroke him - it was driving Edward insane. He could smell everything in high definition with his moist, black nose - a cacophony of delicious food, tart artificial perfumes... pungent body odours. In fact, with his head at waist height, the scent of all these humans' genitals was overpowering. Warm, wet vaginas for him to plunge into; sweaty ball sacks for him to balance on the ridge of his snout and sniff; meaty cock-shafts for him to lick at... The smells were so vivid, he could easily picture each person beneath their clothes and it was driving him mad.

Most of his fellow students backed off from stroking Edward once they noticed the dog's throbbing erection. They quickly decided to pet the placid grey Husky instead. Nate was even starting to enjoy himself a bit, loving the feel of his fur being ruffled by so many hands.

Only Tera, Nate and Edward themselves could see the truth of the situation - that the Husky was just a naked human, covered in soft fur, crawling on hands and knees; and the Shepherd was an insatiably horny boy with a tail, paws for hands and a squat muzzle. The ruse wasn't entirely perfect - as the fact that an otherwise pristine-looking Husky dog didn't have a long, bushy tail seemed to bother quite a few people. Soon, Tera became tired of their concerns and decided to move things along. She had plans for her doggies, and she was especially excited to see them through where Edward was concerned.

The trio approached the campus boundary, crossing a grassy verge and all in very different states of mind. Nate was strangely relaxed, having lapped up the petting - even playing along and rolling over to have his soft white-furred belly rubbed. Tera could barely contain her excitement - everything was going swimmingly, she'd escaped the school grounds with two leashed boys in her custody. Meanwhile, Edward was frenetic.

Wearing a collar, being petted, having dozens of students speaking to him like he was a dog and triggering Tera's obedience rule... it had left his mind entirely broken - unsure of who or what he was anymore. The only constant was the horniness that drove his aching hips to continue thrusting, even without anything nearby to hump. Of course, the dog in him did all it could to fuck everything in sight.

"Down Teddy! Bad dog!"

Edward's mind fizzled into obedience once more as he was forced down from Tera's leg. He'd been so close that time, too! Just a few more thrusts and he might have cum. Somewhere deep inside, his human thoughts paradoxically cheered on his doggish behaviour. He knew that, even though it would transform him ever-more into the whimpering horny beast he was trapped inside, ejaculating was now his only opportunity to feel free of these horny, canine compulsions - if only for a few minutes. His desires unified - he sprang forward and mounted Nate without warning, immediately hammering his cock without precision against his friend's buttocks.

"What?! -Woof- get off, Ted!" Nate cried, reflexively climbing to two feet to escape his friend's advances.

"Nate - for fuck sake - get back down!" Tera snapped, somewhat under her breath.

"-Woof- but..."

"Shh!! We're in public - dogs don't walk on two legs! You want to get seen?! Or, how about... 'if Nathan doesn't get down on all fours-..."

"No! Please... -woof- look..."

Nate, holding his furry hands up with a fearful expression, lowered himself to the ground and crawled a few steps forward, hoping Tera would spare him another 'rule'. She simpered at his gesture.

"Good boy."

"Thank you..." Nate knew he was due a bark and decided now would be an ideal time to gain some favour with his captor. He continued, "-woof-..."

"Hm ha - you are quite cute, Nate. I can see you're trying, but you still have a while to go before you're inhabiting the role as well as Teddy..."

Tera giggled as, perfectly on cue, Edward mounted the Husky-furred boy's rear again, thrusting three or four times as Nate hung his head in defeat, before letting loose a flurry of triumphant breathy barks.

"Whrooof! Whuff-hua-wruff! Whrrrfff... ahhh... grr-god... finally!"

Edward spoke his first human word in quite some time and dismounted Nate, resisting the vestiges of canine behaviour that begged him to sniff and lick at Nate's cum-covered rump. All at once, a feeling of pent-up energy welled up at both ends of his body. His head felt warm and loose - like he'd just gotten over a bad cold, while his legs and feet were in dire need of a long, indulgent stretch.

He obliged, arching his back and letting his hips lower to the ground as he stretched out his legs behind him, muscles quaking with delight. Tilting his head up to the sky, he pushed his black nose as far forward as his neck would propel it - teasing out the knots in his shoulders with a few shrugs as he did.

While the boy stretched, so too did his ears - elongating and forming a blunt point at their peaks. A familiar brown fuzz, albeit a lighter shade, grew in to cover the erect, triangular ears as they migrated up Edward's head and sat amidst his fluffy brown hair. At the same time, his legs were thinning and becoming more sinewy - feet shrinking into clawed padded-paws to match his forearms. A brush of brown and black fur washed up his new lean legs, thicker around his thighs and lower back, until it met with his bushy tail.

Edward only noticed the changes as he finished stretching and attempted to resume his posture on paws and knees, fumbling his way to the ground instead. He no longer had knees - rather, his back legs were now the perfect length to adopt a truly quadrupedal stance. He glanced round at his hind quarters - he was now just a normal dog from the waist down.

"Welcome back, Teddy! Such big and cute ears!"

"Yeah... great to -woof- see you, Ted." Nate looked over his shoulder, reaching a hand back and despairing as his friend's sticky fluids caught in his nice, grey fur.

Edward winced with the deafening volume of their speech as he formulated his reply.

"Fuck you both."

Tera formed a barbed riposte in her mind, before stopping herself short of saying it. 'Both?' This sudden anger at Nate was unexpected... but seemed like it could be fun. She resolved to stay quiet and see how it played out.

"-Woof- what?!... I mean -woof- I understand you're -woof- angry with Tera -woof- but..."

"Oh - stop barking, Nate. You idiot!"

"...You know -woof-... I can't..."

"So what?! You want me to feel sorry for you? You don't have a fucking clue. I've probably got a few minutes max before I wag my tail or lick my paw... get fucking horny... and then start barking and humping shit again!"

"Ted... -woof- I..."

"And then I just have to wait! Can you imagine that?! I just fucking wait, trapped in my own deformed body, feeling horny as shit - until I can cum. Then... guess what? I lose _another_part of my humanity and get to have about five minutes of speaking English before it starts all over again..."

Edward abruptly stopped, tears welling up in his eyes and catching in the fur of his short muzzle as they fell. Nate stared in shock at his friend's outburst. He wondered what he should say, his voice quivering slightly as he hesitated.

"Ted, I -woof- wouldn't even be -woof- covered in fur -woof- if I hadn't -woof- tried to help -woof- you..."

"Maybe... but maybe neither one of us would be at the end of a fucking leash if you'd just believed me to begin with!"

"You can't -woof- blame-..."

" Why can't I blame you!? Grrghgh-you're all too happy to help with Tera's sick game now!"

His jowls pulling taught, Edward snarled and growled as he bore the sharp teeth of his muzzle in anger. His tears had stopped now - a fierce glare replacing his damp sombre eyes.

"What do -woof- you mean?!"

"Grggh-ruff-grr! You restrained me back there while she put a collar on me!"

"But-..."

"You know what that would do to me-wrrf! More dog, more horny - more... arff- fucking... dog! Wrruff-walking on a leash is a pretty dog-specific thing, you vacant prick!"

"-Woof-! It was our -woof- only way out! -Woof- and you weren't -woof-... yourself... I had -woof- no choice..."

Edward's snarl evaporated.

"I'm scared Nate... We need help! I'm enough parts dog that it's becoming impossible to avoid behaving like one!" A pained whine rose in Edward's throat to punctuate his words, "I think... Soon - I might-rrf never be myself again... I wrff-want someone to notice us. It's the only way."

Nate shot a sceptical look back.

"Tera -woof- can't keep us -woof- like this forever..."

The muzzled boy's jaws contorted with anger again as a deep, guttural growl rumbled out from his throat.

"Grrgh-arf! She shouldn't be wrrf-allowed to do this to us at all! You're too naïve! Wruuff!"

Letting his anger overcome him, Edward engaged his springy new back legs, jolting forward and clamping his razor-lined muzzle onto Nate's furry shoulder, tearing away a chunk of fur. Nate shrunk backward and fell onto his flank as the snarling dog-boy continued to growl at him, bloodied grey fluff adorning his snapping jaws.

"Stop it, you two! Teddy - Bad dog! Sit!" Tera finally intervened as the altercation had grown violent, tugging at Edward's leash.

Edward's snarl faded as he licked the strands of fur from his muzzle and stumbled sideways. His pointed ears flattened to his head.

His mind was fizzling into nothing again - just like before. He wondered if he could fight it - he was more cognizant than he had been earlier, with his balls freshly emptied. He felt his lean back legs trembling. It was as if he could visualise his human influence as a huge bubble in his mind. Tera's words, speaking to him like a simple dog, had brought a sharp needle right to its border. He willed the point backward and locked his legs in place, whining with the exertion.

"I said sit!"

Her stern tone drove the needle forward, piercing his human thoughts and as they popped out of existence and his back legs buckled. He fell to his haunches - tail brushing the floor and panting. His cock, which had been become semi-aroused during the argument, began to rise and harden.

"That's better - good boy!" Tera patted Edward's head between his velvety ears.

"Wroof! Waff!" Edward barked obediently, now rock hard.

Nate looked relieved, eyes relaxing a little from being plastered open in fear. He was glad to see his vicious canine friend back under control.

"-Woof- I thought he -woof- might tear my -woof- throat out... Thanks... -woof- Tera..."

"Don't thank me yet, barking boy. Teddy has a point - don't you think?"

Nate's brow curled with confusion beneath his thick grey fur.

"About what?"

"Well... you don't have a clue what he's going through, do you?"

"-Woof-..."

"Let's give you a taste..."

"No! Tera - no! -Woof-! I've been a -woof- good dog!"

"Shh! Come on, now. I admit you've made things easier than Teddy - but I'm not in the game of making things all fair and equal..."

"B-but -woof- why do you -woof- want to make -woof- me... like him -woof- then?" Nate nervously looked sideways at the panting half-dog, sat obediently.

"To be honest - I'm just sick of those obnoxious butt-cheeks staring me in the face while you're crawling on your leash... It's that simple."

"What?"

"Yep. Now let's see... 'Whenever Nate barks, his tail will lengthen an inch until fully-grown'... and 'Every time Nate's tail wags, he will bark with joy'. That should work fine!"

Tera advanced toward Nate, reeling him in by his leash, and slapped his furry rump. The glow in her pocket could be seen faintly in the outdoor sun.

Nate felt his muscles tighten up in anticipation as he placed his hand at his coccyx... Nothing. He left it there and waited, looking up to meet Tera's blank stare.

"But...", he began.

"But what?"

"-Woof- I don't have -woof- a tail..."

"Are you sure?"

Nate tuned out her rhetoric, as before he'd even finished speaking - something prodded at his furry palm. Squarely at his coccyx, he felt a small nub raise up and force its way forth. He pinched the burgeoning appendage between his finger and thumb, his grip widening as it expanded, and plied it back and forth. A restlessness built around his lower back and upper buttocks, causing him to quickly let go of the two-inch protrusion, recalling Tera's new tail-wagging 'rule'. He needed to be careful not to wag it... or speak.

"You catch on quick, Nate. But you'll be barking again soon enough - don't worry."

Tera turned to Edward.

"Ready to re-join us, Teddy? I hope you've simmered down."

Deep inside the muzzled boy's body, human thoughts stirred and surged to the surface again. As soon as he was back in control, Edward was immediately greeted by the pressure in his manhood and set about forcing his rebellious body to stop panting and wagging its tail.

"Wrrf-when do we ruff-find out the point of all this, Tera?"

"I've been clear on that from the start, Teddy..." Tera leant down and grabbed Edward's tail at its base, waving it around like a feather-duster as she spoke, "Fun. That's really all there is to it. Just fun-..."

Tera stopped, letting Edward's tail fall limp as she tracked his focus over her shoulder. Nate quickly lowered his hands and hid them behind him, eyes darting to the floor.

"You think I'm stupid, Nate?... Hand signals?!"

Nate looked her in the eye meekly and shook his head side to side.

"Liar! 'Any time Nate's hands are not in contact with the ground, they will slowly shrink and become more like paws'. I'm not stupid." She flicked his forehead. "But you will be if you don't stop pushing your luck. Dumb dog."

Nate suddenly felt a numbness in his palms, facing them up to get a look as a number of tough, pink and black splotches rose up and calloused through his fur. He thrusted his mutating hands to the ground, squirming slightly with the alien feeling of pads on concrete. Suddenly it occurred to him that he'd need to lift them up to take steps - this wasn't fair at all! Burning up with injustice, he spoke without thinking.

"What -woof- about walking?!"

Nate winced as he felt the nub at his backside grow another inch, long enough that he could now feel it resting between his butt-cheeks. It wriggled faintly. Stop! He had to keep it still.

"Not my problem. We've wasted enough time. Let's go."

Tera tugged at both boys' leashes and made a stride down the road toward the tree-lined street where she and Edward lived. The muzzled boy rose to his four paws and nimbly trotted in front - he couldn't afford to resist if he was going to maintain enough humanity to attract someone's attention. He had to pick his moment.

Meanwhile, a silent Nate crawled forward reluctantly, grimacing as each step puffed his tough paw pads out further. He could feel his fingers becoming stiff and hung his head down, watching dark claws sharpen at their ends as they receded.

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

Part 8


Cornering onto the familiar tree-lined street where Edward and Tera lived, Nate felt hopeless. His hands were no more, having steadily become inflexible padded-paws, only useful for walking and digging. The worst part had been the sensation of his thumb migrating up his wrist and becoming paralysed as it shrivelled into a vestigial dew-claw. His tiny tail nestled deeper between his butt-cheeks, signalling his anxiety.

Edward had reached a state of inner calm - refusing to allow himself to dwell on his canine predicament or his hard cock, and thus slowing the horny cycle to a crawl. He had four legs, a bushy tail, pointy ears and a whiskered muzzle. He knew this was his last chance to escape from Tera... somehow. He knew she could just take control of him by speaking to him like he was an animal - and he didn't want to be forced to 'sit' again, his neck fur raising on end at the thought of the humiliation he'd endured.

He thought hard - Nate was no use, especially now he had paws too. He needed to get someone's attention. No sooner had he reached this conclusion than he squinted to see a figure approaching on the same side of the road down his street. He couldn't quite make it out, instinctively sniffing the air with his nose to get a better idea... It was a man... young-ish... sweat... and coffee? The figure approached closer.

A policeman! Yes! Edward stopped himself barking with excitement and struggled to keep his tail still. He couldn't let Tera suspect anything. This was his one shot. He waited and kept his pace.

The trio converged with the police officer on the pavement, only a metre from each other. Now or never, Edward told himself. He concentrated hard - this _needed­_to come out in English! He pulled forward at the length of his leash and shouted.

"Grrrrh- Officer! Help! Wrrf- this girl is wroof- holding me prisoner! Wruff! "

The policeman stumbled off the curb in shock. He straightened himself up, stood in the road and staring at Edward. Tera quickly choked the shouting boy with a firm pull on his leash.

It didn't matter - he'd done it, hadn't he? No-one was just going to ignore a talking dog.

"Is that your dog, young lady?"

"Yes... officer." Tera replied, now holding Edward by the collar.

"You need to get that animal under control, or it'll fall under the remit of dangerous dog legislation and may need to be put down!" The policeman spoke with a quaver in his voice, still clearly shaken.

"I don't know what's gotten into him, he-..."

This wasn't right, Edward thought. He needed to try again. He lunged forward, shouting once more.

"Wruff! You have to help wrrf- me!"

The policeman flinched and took a step back from the barking beast.

"That's it - you restrain that dog!" He reached for a notepad in his chest pocket, "I'm going to need to take down your details for further investigation, miss. That animal clearly poses a danger."

Edward's ears drooped flat as Tera reeled off her details to the officer. She easily convinced him to let her to take the dog home, considering she only lived thirty seconds down the road. He searched his mind - that should have worked. He definitely spoke human words. He looked toward Nate for confirmation.

"Wrrf-I spoke human, rff-right?"

Nate glumly nodded, hoping Tera wouldn't see him do so out of the corner of her vision.

"Sorry again, Officer...?"

"Officer Brady."

"Please, Officer Brady - come around later and I'll show you how well-behaved Teddy is. I promise he's a good dog really."

Tera simpered and clutched at the officer's hand, squeezing slightly as if to punctuate her plea.

"Well okay, miss. But I still need to file this report with the station. You just get that animal back home for now."

She nodded in compliance and stuck her hand in her pocket as the officer turned to walk away.

"'The closer Officer Brady gets to the police station, the more he will transform into a filthy pig'." The tell-tale glow emanated from her pocket as she whispered. "No way he'll be filing that report. Stupid pig."

The two leashed boys watched the officer disappear down the street and shared a look of pity.

"Did you think the collar wouldn't work for speech, Teddy? You should know that's a risk I wouldn't take. To everyone but us three, you're just a barking animal... Anyway, let's get you doggies home."

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

Inside Tera's hallway, Edward could smell a thick waft of sandalwood, cocoa and vanilla. Seemed like she was burning incense - and the lights were all dimmed. He'd already noticed the drive was empty on the way in, so her parents must be away. Whatever she was planning, she had set the scene before coming to capture him and Nate at the campus. The ambient sweet smells only distracted his mind for a moment before he returned to the constant pressure in his swollen cock. He knew he was getting close to going full-dog again and needing to cum before he could reset. The fact he'd desperately barked at his house five-doors-down, hoping to get someone's attention, hadn't helped. Each futile bark had tipped his canine libido further into a frenzy.

The two dog-boys were led into a side room where the blinds were drawn shut and plump mattresses lined the floor. Wall-mounted lights flickered as if emulating candles, while the ribbon of incense twisted all around the room with the air-current.

"Okay - here we are. The main event." Tera unlatched the leashes from both boys' collars. "Now - I'm sorry Nate... With hindsight, I should have lured that policeman back here and made him into a bitch for you. I was just too angry to think of that at the time, so... how about this pillow?"

Nate stared at Tera incredulously as she lifted a firm rectangular pillow and threw it into the corner of the room.

"Don't look at me like that... you'll thank me in just a moment... now let's see - right now, you bark happily when your tail wags and every time you bark it grows longer...hmm. What about 'when Nathan's tail is fully grown, he will become a thousand times more horny - but he cannot cum until his body fully transforms into a dog'?"

Nate's eyes narrowed as he analysed the rule in his head.

"I know, I know. You're thinking I've forgotten something. 'Every time Nathan thrusts into his favourite pillow... he will transform further into a dog'. Better?"

Tera tapped Nate's nose and the whites of his eyes widened as he pieced together what this meant.

"There you go - you see? You'll be begging to hump that pillow soon enough... now let's start things off..."

She knelt down next to Nate and unclipped his collar, removing it. He flinched, but before he could move at all, she immediately clasped the collar tight around his furry neck once more. A familiar surge of desire shot through him as his muscles tightened, his scrotum clenched, and his dick flew to full mast. Squeezing his eyes shut through the injection of pleasure, Nate was unable to react as Tera unclipped and re-applied his collar once more, making him shiver and shake with lust.

With his pelvis jammed in a forward position, Nate pawed at his rigid cock - finding little use in his rough pads as he writhed in ecstatic agony.

"Pillow's over there, Nate. Go enjoy yourself - I'm looking forward to that tail, yeah?"

Knowing exactly what it would do, Tera scratched Nate's head for a couple of seconds until his stunted tail twitched and came to life.

"Wruff!!"

Nate was surprised by the volume of his own bark as it came out louder than usual. He felt happy to announce his pleasure to the room and barked again before reminding himself of the new rules. He flung a paw round to his rump and held his now longer, thicker tail still. It struggled to wag, but he knew that if he wasn't careful, a vicious cycle of wagging and barking would start, forcing it to grow. And if that happened - he reasoned, fondling his dick with his free paw - he'd be a thousand times hornier and pillow-humping away his humanity might not seem so bad.

Tail trapped under one paw, Nate took a tentative step toward the pillow - which seemed to be growing more tempting by the second.

"Now for Teddy. I've got something so special for you, fluffy little doggy."

"I don't wrrrf-want anything from you Ter-rruff!"

"I don't think you know what you want. Just sit."

Edward didn't bother resisting as he felt his thoughts fizzle and the familiar compulsion rise up within him. He sat onto his haunches and barked in compliance, his human penis flexing with excitement as he tucked his paws neatly in front of him.

"Good dog - but first, I want to make sure you're ready for your special gift..."

Tera lowered herself and led next to the obedient dog-boy, stroking along the side of his soft muzzle and petting above his haunches, across his lean brown-furred thighs. Edward panted in response, his absent mind allowing his canine body to turn and lick affectionately at the girl who'd imprisoned him.

She ran her hand along the grain of his thigh fur, allowing it to fall free at the point where the boy's knee used to be. With a circular motion, she weaved her touch back around and all at once, wrapped her fingers around Edward's engorged maleness, squeezing gently. The dog-boy whimpered with the pain of his pent-up seed, ready to spill.

Tera knew it would only take a few strokes and purposely moved tantalisingly slow - up and down the rigid shaft, tickling the sensitive tip on each up stroke and lightly massaging his firm ball-sack each time she reached the base.

"Is this what you want, Teddy? Feel how your cock responds to my touch..."

"Worrruuff - wrrff!"

Though Edward was far too horny to form words, his human mind had resurfaced and did nothing to fight against Tera's petting. He flashed back to the time behind the library, how she'd worked him up effortlessly without even removing his clothes. But this was on a whole different level - dog 'rules' or not... he was undeniably at her mercy. He felt his whole body clench up at the point of no return.

"I can feel your cock spasming, aching to squirt out your humanity - all over me. Do it. Accept that you're just a horny dog - cum for me, Teddy!"

Tera began pumping Edward's iron shaft as it jolted. He barked and convulsed, feeling his legs go weak as he struggled to breathe through the mind-shattering orgasm that wracked his brain and body. His cock took full control, forcing his hind quarters to thrust forth with each shot of cum that exploded from his swollen, throbbing manhood.

It began before he even had the chance to catch his breath. His dick started to feel alien as it softened, more tender than before and trapped at a strange angle - flat up against his stomach. A feeling of warmth enveloped his whole shaft, feeling like his penis had been zipped up in a cosy sleeping bag. His balls felt indescribably altered as they loosened and began to dangle once more - like they were the same... but something had changed within.

With his first full breath after the most rapturous orgasm he'd ever experienced, Edward tilted his head to examine his groin. It was peppered with creamy-brown fur, the skin of his scrotum was darker and his cock was nowhere to be seen. He gulped, flexing his pelvic floor muscles and saw the fuzzy-furred sheath that was held tight to his abdomen twitch. He knew the thing that had made him a man was now encased within. He knew he now had the genitals of a dog.

Understandably distracted by this monumental change in his physiology, Edward had neglected to realise that the rest of his body had further shifted toward canine proportions too. Brown and black fur had sprouted all along his back and flanks, his chest taking on a more puffed out appearance while his abdomen tucked in. His torso and belly were covered in a cream and brown silky fluff that would feel incredible to stroke, while his arms had locked forward at the shoulders - just another pair of legs now.

Tera wasted no time and began to rub his soft belly immediately after prodding his new sheath with delight.

"Tera... look and tell me honestly... Am I just a dog now?"

"Almost, Teddy. Your muzzle is still a bit on the short side. But just so you know... I've thought of you as a dog all along anyway."

Edward lowered his head onto his front paws, belly meeting the floor as he led down in defeat.

"At least take this collar off me... it's itchy..."

"But dogs have to wear their-..."

"Please."

Tera thought for a moment, before deciding that it couldn't hurt - Edward was nearly indistinguishable from a large German Shepherd dog at this point anyway. She unclipped the collar.

"Thank you."

Edward's voice was monotone, glum and gravelly - his nearly-canine vocal chords lending themselves poorly to human speech. He looked over at Nate, reluctantly but inevitably thrusting back and forth into his pillow.

"What about him?"

"Oh, Nate? Looks like he's been busy too - starting to get a nice black nose from all that thrusting... and his tail isn't even fully grown yet!" Tera raised her voice to shout in Nate's direction, "You should live up to your nickname and let loose that tail, barking boy!"

"Hmph. So, we never had a chance, huh?" Edward lamented.

"Oh, Teddy. Don't act so down... I said I had something special for you, didn't I?"

Tera reached into her pocket and brought out a half-palm sized stone, setting it on a side-table. Edward watched closely as it shimmered with refracted light but maintained a pure transparency. The central stone was encapsulated with a mesh of cobalt-hue metal. It was like nothing he'd ever seen.

"So that's what was in your pocket... What is it?"

"A rule-stone. Does exactly what you'd imagine. You've already seen it first hand, of course. And now it's time to really have some fun."

Tera placed her hand onto the stone, placing her other hand against her own forehead.

"'Tera will now transform fully into a female dog in heat, and she will only change back when she orgasms - but she will keep her ability to talk throughout'. I'm not above the rules either, Teddy..."

The stone began glowing as the refracting light span around at its centre and Tera began to sprout white fur across her face.

"What do you think, Teddy?" She asked, as the fur grew in thicker and a black splotch began to spread outward from the tip of her nose. Edward looked on in disbelief that she would do this to herself, and then rose to four paws as her motivation became clear.

"Seriously?! This was your endgame? You just wanted to-..."

"Fuck you doggy-style, yeah. But authenticity is important, and I was lucky enough to have the means, so-..."

She spoke casually as she shed her clothing, revealing ten breasts adorning the length of her torso. The white fur was growing in patches all over her fair flesh, spreading and merging to form a full coat.

"Damnit Tera! And all that teasing? Taking the piss out of me?"

"I like you, Teddy. Always have... and now I get to have you."

Her face stretched out into a muzzle as she flashed a sultry, toothy smile.

"But... why didn't you just say? Hell... if you'd told me about the stone, I probably would have been up for spending an afternoon with you - fucking like dogs... or anything really!"

"What do you mean?" She looked confused, as she held her fresh paws limp and folded forward at her chest.

"I've always liked you too, Tera - but you seemed so... frosty and hostile, I didn't know how to say it."

"Really? Then you can't be angry with me - you know what it's like!" The dog-girl exclaimed defensively as she fell forward onto her front legs, tail pushing out and waving through the air at her rear.

"But you did this to me against my wrrf-will..."

Edward felt his nose sniff involuntarily as Tera's scent tickled it and lit a flame in the back of his mind.

"So? Isn't that even hotter? I saw how hard you got behind the library. How quickly you came when I commanded you to cum for me... Let's run with that. Fuck me, Teddy."

The white Labrador turned to face away from the conflicted dog boy, presenting her oestrus-engorged lips to him as she cocked her tail to the side and swished it to waft her thick scent.

"Wroff wrrff-ruff! Grrgh-but... why did it have rrrf-to be like this? Wruff!"

The overpowering smell and the sight of her dripping wet opening before him quickly overpowered any sense of human etiquette as Edward padded forward, groin heavy with lust. Just the feeling of his brand-new red rocket-shaped dog cock extending from his sheath ramped up his arousal and got him barking under his breath.

"Yes Teddy! Mount me and fuck me like the horny dog you are!"

Tera's encouragement was entirely unnecessary as Edward, already blinded by the compulsion of her canine charms, reared up and plunged his tapered tip deep into the white dog-girl. It only took a few moments for his legs to find their rhythm and start to jack-hammer his bulging beast deeper and deeper. Her juices lathered his slick cock while he drove in and out, but still he felt some resistance as he strained to push his bulbous knot past her puffy lips and fully immerse himself in her warmth. With three gargantuan piston-like thrusts and using his paws to pull his bitch back onto his raging hips, his whole length finally entered her - locking him into place. He growled and slammed into her hind quarters with erratic micro-thrusts. His climax was seconds away.

"Tera?!" A voice rang out from outside the front of the house, followed by someone banging at the door.

Part 9

"I don't need to tell you to ignore it, do I, Teddy?"

Tera's muzzle approximated a smile as she was viciously rocked by Edward's animalistic pounding. The door knocked again and then silence. Edward continued fucking her, nipping at her nape with his sharp fangs and curling his paws back to clamp her to his pneumatic cock.

" Tera?! I've let myself in through the window... I know you're in - I can hear the dogs barking!"

"Shit. Who the fuck is that and why would they let themselves in?! Fucking barking boy!"

Nate had been intermittently barking as he humped the pillow and battled the impulse to wag his ever-growing tail.

"Tera?! Where are you?! I've got Barter's trousers and I know he was with you earlier - I tried his house, but his dad said he wasn't in! Come on!"

Edward's ears perked up at the mention of his name... he recognised the voice, somewhere deep down in his mind - buried beneath all the fucking and barking. He continued ramming his cock into his bitch.

Tera weighed up the situation and knew she would need to respond.

"Okay! I'm busy! Just leave them in the hall and I'll get them back to him!"

The handle to the dimly lit side-room turned and the door creaked open, revealing Adrian as he peered his head through.

"There you are! I-... what the FUCK ?!"

The stocky jock let the door swing the rest of the way open and dropped Edward's trousers on the floor as he surveyed the dank room. He was greeted by two dogs fucking on a mattress in the middle of the room, while a third dog wearing a collar slowly humped a pillow in the corner, clutching its tail with one paw. The smell of canine sex overwhelmed the sandalwood incense that misted up the air.

Tera felt her veins flood with panic as she instinctively shot a glance at the rule-stone. She went to lunge for it, but found she was unable to move. Held back by the tight grip of Edward's paws and his enormous cock anchoring her to his pelvis as he pumped out his final few thrusts.

Adrian stared with a morbid curiosity as the German Shepherd howled and barked in climax, skewering the white Labrador bitch with its thick rod. The jock had forgotten to wonder where Tera's voice had come from amidst the shock and disgust of the scene before him.

"Wrrrffff-rufff - wrrof! Wrrf-Adrian!"

"Huh? Did you just..."

Adrian's face creased up as he felt lightheaded - that dog had just spoken!

Edward knew he didn't have long in-between emptying his balls, regaining his human mind and then losing the ability to talk for good as his body completed the transformation into a dog. He forced his sentence out as best he could, feeling his muzzle start to stretch forward as he spoke.

"It's me - Edward! Grrgh-get the... wrf-stone! On the table - ruff!"

Hearing the beast on her back giving the game away, Tera made a snap decision to intervene.

"Good dog - Edward, good boy - shh!"

Edward's attempts to speak melted into a contented panting as his thoughts fizzled into obedience, but the damage was done. Adrian had heard both dogs speak.

"Tera?! Is that you in there?"

Tera was out of her depth. She hadn't planned for this and didn't know how to answer.

"And Barter?!... is a dog... A dog that's fucking you?! And you're a dog too?! What in the fuck is going on here?! So then - who's that?!"

Adrian pointed at the collared Husky dog, humping a pillow - his tail almost full-length.

"That's Nate."

"Who the fuck is Nate?"

"Never mind. He's Edward's friend."

Adrian shook his head, blinking his eyes shut then open and refocusing on the white Lab.

"I'm talking to a dog... with Tera's voice... this is insane. And you, Barter - some kind of fetish this is!"

"Yeah - things got a bit out of hand, so if you could just pass me the stone from that table..." Tera calmly instructed.

"Oh right, yeah."

" Wroof! Grrrrgghhhhgh." Edward could no longer form words, but he decided he could still get his point across just fine.

"Whoa there! Barter doesn't seem too happy about that idea... you good there, Ed?"

" Grggghhgrrghhrrr-ruff!"

"That is one angry dog... especially considering he just got through fucking you. Why is he so pissed?"

"Just ignore him, Adrian. He gets like this when he's a dog... pass me the stone."

Tera tried to move again, but couldn't, still tied to Edward by his inflated knot.

" Ruff! Wruff!"

Adrian searched Edward's snarling, growling face for answers as he barked.

"Hold up. Let me work this out... bark for yes and stay quiet for no, okay? Errm - say hello like those dogs on youtube if you understand me..."

'Yes Adrian!' Edward thought to himself in celebration of the handsome jock's intellect, albeit not thrilled about being forced to do party tricks. He begrudgingly obliged.

"Eh-rrooh... ruff!"

"Shit... so those videos are fake - they're just people changed into dogs?!" Adrian announced his revelation.

"Just give me the stone!" Tera barked.

"Calm it Lassie - let me get Barter's take... So, I'm guessing you don't want me to give that gem-thing to Tera?"

"Wruff!"

"Okay. Because... it belongs to you?"

"..."

"No. Right... Because... she's a witch?"

"Rrrf." Edward barked under his breath in semi-concurrence.

"Warmer huh? ... shot in the dark here - because she used it to turn you into a dog?"

"Wrooof!!"

"Wow. Okay, then. Looks like you're not getting that stone, Lassie. But what do I do with it then, Barter?"

"Fuck off, Adrian - just give me the stone and stop taking orders from a dog!" Tera spat with vitriol as her calm demeanour further cracked.

"Aaand that's exactly why I'm not giving you the stone..." Adrian looked to Edward for answers, "Barter?"

Edward searched his mind - how could he communicate the way in which the stone worked? His attempt at saying 'hello' had already demonstrated that his muzzle wasn't going to suffice.

A-ha! Nate. Edward loosed a few soft barks and pawed at his neck, then pointed with his other paw at the dog humping the pillow.

"You want me to take off his... collar?"

"Wruff!"

Perfect, Adrian was on a roll - as long as Nate could still talk, he could explain the rule-stone and how it works the moment the collar came off. He didn't look too far gone - black nose, tail, paws, triangular ears... covered in fur, but his muzzle hadn't stretched out yet. Edward prayed for Nate to still be cognizant as Adrian approached and unclipped the collar.

The second the muscular jock lifted the collar over Nate's head, the illusion rule faded and Adrian fell backward as the Husky appeared in its true form. Just a furry naked boy, with paws, dog-ears and a tail. Nate didn't stop humping the pillow.

"Uhhm - Nate, was it? So, what's Barter trying to tell me?"

Nate hesitated, knowing he would have to bark at least a few times in order to reply. With a paw, the furry boy clumsily reached to his backside, estimating the length of his tail. It was already so long - just a few more barks and he'd be a thousand times hornier. He couldn't even imagine what that would do to him - he'd have to speak quickly.

With some difficulty, he turned to face Adrian - depriving his raging cock of the pillow it had grown so fond of. He looked at Edward, tied to Tera, and steeled his resolve.

"..."

"Well, what is it - furry guy? Why's everyone so cagey about this gem-thing?!"

Nate held up his paw pad, gesturing for Adrian to wait for a moment. He thought as deeply as he could while his cock bobbed around, spilling pre and demanding more pillow-action. He'd have to bark way too many times to explain how the rule-stone works to Adrian - his tail would finish growing and he'd probably happily fuck the pillow until he was eating from a bowl. But he could surely make a single rule before succumbing to his libido, couldn't he?

So - he could change himself back?! Tera had just placed a rule on herself by touching her forehead. But maybe there's some special method to it? It was too risky, he thought. Ted would know what to do! Maybe if he could change Ted back? Yes! That's the safest way.

Nate gestured toward the stone, making an exaggerated 'come here' motion with his paws. Adrian's eyes followed his body language across to the cobalt-webbed gem.

"So now this guy wants the gem! You good with that, Barter?"

"Wroof!"

"Don't you dare give that half-breed freak the stone! Give it here - now!" Tera screamed in a shrill tone, her heart thumping with dread.

"Bitch please be quiet! Your attitude is something else..."

Adrian scooped up the rule-stone and held it up, staring into its whirring clear-crystal centre as he walked over to Nate.

"Here you go, dog."

Tera suddenly felt the knot tying her to Edward's groin loosen. She suppressed a grin and hoped he wouldn't notice his dick softening inside her. She needed to bide her time 'til the right moment and steal the stone back.

Nate balanced the rule-stone on his upturned black pads - using both paws to sandwich it in his grip - and took a deep breath.

"'The moment Edward -woof- touches me, the -woof- effect of every -woof- rule placed on -woof- him will be -woof- reversed!"

He watched an incandescent glow erupt from within the stone and bathe his paws in delicate light. It was working! But he could feel his tail pushing out further in response to the barking.

Adrian bit his lip and screwed his face up, watching incredulously as the half-Husky boy stared deeply into the glowing gem, grey-speckled tail growing longer and beginning to wag behind him.

"WOOF!" Nate let loose a huge bark and fumbled the stone - dropping it to the ground as it stopped glowing. He panicked and tried to paw at his rump, missing his tail as it swished around and forced him to bark. "WOOF!" The wagging intensified. "WOOF!" He couldn't catch it. "WOOF!" He didn't want to catch it. "WOOF!" Barking is fun. "WOOF! WOOF! WOOF!"

He stopped and fell silent. The pupils of his eyes dilated, forming huge black saucers.

"You okay, dog?" Adrian checked with concern.

Nate felt it. His cock had already been straining throughout - his mind already working overtime in the background on how best to pleasure himself. The pillow. He had fought through it until now. The pillow. He had tried his best - tried to save his friend. The pillow. He'd held back the wagging... and the barking. The pillow! But now he knew... his tail had finished growing. His heart palpitated - blood gushing to his groin. He needed to fuck... that... PILLOW!

"Uhh... Nate, was it? You good?" Adrian checked again.

The half-Husky spared a brief hollow glance at the jock before collapsing onto the pillow in the corner of the room, hunching forward, pressing it tightly to his pelvis with his grey paws, and fucking it like a mindless animal.

"Wow... so - what the fuck now?" Adrian threw his hands in the air, shrugging as he openly questioned the room and watched Nate's features become a hint more canine with each frantic, desperate thrust.

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

Edward observed his friend and pitied his predicament, knowing roughly what it must feel like. But hopefully, it wouldn't be for nothing - he just needed to touch Nate and this nightmare would be over. He tested his tether with Tera, noticing that he'd softened and began to withdraw.

Before he could fully exit her warm opening, the bitch twisted - bearing her sharp teeth and bit into his front-left paw.

"Grrghhg-arf!" Edward growled and barked at the sudden stabbing pain.

Before he could react, the devious white Lab had shot out from his reach and scrabbled over to where the stone dropped. She quickly placed a paw on it.

"'Every time Adrian takes a breath, he will transform further into a female dog'!"

The stone whirred to life once more, shining dimly, as Tera pounced at Adrian - grazing his leg with her claws.

"The fuck?!" The jock kicked the white Lab hard, causing her to yelp as she rolled away into the corner of the room, landing next to Nate and his beloved pillow.

Edward watched in trepidation as Adrian's muscular bulk began to deflate before his eyes. It was mesmerising - like some weirdly erotic body horror CGI.

"Jesus fucking CHRIST! What's happening to me?!"

Adrian screamed, as his deep bass-y voice began to crack and climb higher in pitch. He looked at his arms, flexing a bicep to no applause as the muscles he'd trained so hard to achieve began to thin and flatten. His chest began to swell, as burgeoning breasts inflated into existence - nipples visible through his top.

The ex-jock was hyperventilating with fear, spurring his changes on further. Tera, the wind knocked out of her, simply observed from the corner next to Nate, as Adrian made the connection and unzipped his fly. His ample beefy manhood had already started to shrivel - now sucking itself back in at the base as a thick pair of labia enveloped the area where it had hung.

"Stop this, Tera! I'll do anything! Just stop this!" The newly forged girl begged as her pubic bush began to darken and grow thicker.

"Should have given me the stone, Adrian! Now... you'll make a great bitch for Nate to fuck... once he's done with that pillow! ...Ha!" Tera, still a bit winded, forced out her taunting riposte between breaths.

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

Edward shook his head and glanced around the room - this was bad. He needed to touch Nate - NOW. He sprang from his haunches toward the half-Husky.

"Good dog Teddy - bet you thought you boys had this all wrapped up, didn't you boy?! Good doggy - SIT!"

Edward's impetus melted into nothing and he was soon sat back on his haunches, panting and drooling - for all intents and purposes, nothing but a regular German Shepherd dog, doing exactly as its owner had commanded.

"Don't worry Teddy - I'll let you fuck me 'til I howl and then rub your belly once I have my hands back. I just need to get things back under control here first... Good dog."

Tera surveyed the room - looking at each boy in turn, Edward sat in an obedient trance - pawing the floor in front of him, Nate right next to her - tongue lolling out and dangling past his chin as he fucked his pillow, and Adrian - tears snaking down her cheeks as she grappled at her new breasts. The trembling girl had now fully undressed to better track the changes as they stole her masculinity.

"Aww don't look so upset so quickly - you're no way near done yet!" Tera jeered.

The weeping girl could barely focus her eyes on the white Labrador, as they filled with salty moisture. She ran her hand down from her ample breasts to her groin, as if doing a physical double-take, and groaned in agony at the absence of her dick and balls. Her hips widened, her jawline softened, and her shoulders narrowed - she now instinctively covered both nipples with a forearm as she stood daintily against the wall. The groaning began to shift in tone.

Adrian, now fully female and entirely nude, stood with her finger pressed between her labia, slowly and sensually rotating it across her clitoris. Her other hand, which had been covering her nipples, now abandoned any notion of modesty and groped at her chest - fingertip circling rings around her areolae. She moaned and shook with pleasure, her abdomen quivering as she drove herself toward orgasm.

At the very moment she released cleavage in favour of sticking two fingers inside her fresh, dripping pussy - eight more nipples began to swell along the length of her torso, quickly sprouting a fine black fur around them. The girl was too caught up in the pursuit of her first female climax to notice the changes now blanketing her entire body. Black fur bristled into being all over. That pretty face stretched out as her teeth sharpened. Her ears grew flat and folded forward, hanging at the sides of her head.

Her first clue came as she felt her digits begin to seize up inside her vagina - she'd been gently stroking the warm walls of her sex and was beyond frustrated as her rhythm was disrupted.

Withdrawing her fingers, she opened her eyes and returned from the all-encompassing passion in her mind's eye to see the beginnings of hairy, dirty paws. The sight brought her crashing back to reality as her other paw slowed its circular motions over her moist lips. She was meant to be a human boy - not this!

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

Tera, still nursing a small limp, slowly rose to all-fours - ready to venture from the corner and reclaim the stone permanently. Her mind flitted from thought to thought - what would she do to Adrian next? What punishment would she enact? How good would it feel to finally be fucked to orgasm by Teddy?

She'd won! She couldn't help but plaster a shit-eating grin across her canine muzzle as she stepped a paw forward toward victory. Her mind was so absorbed in the fantasy of her domination over these three boys - she didn't even notice the humping Husky behind her.

Almost completely a dog and mere seconds away from soaking the dick-battered pillow with his thick load, Nate engaged the last vestige of his human will and reached out with a limp paw. Shakily, as he was jiggled back and forth by his own bucking hips, he lined it up and swiped at Tera's tail - grazing the tip with a claw. She padded slowly out of reach toward the stone.

Nate felt his dick ballooning in size - knot inflating as his shaft grew iron hard and the furry orbs at its base contracted and shuffled in their sack. The tickle of his dog-juice rippled up the inside of his member as the first jet of semen tore out and painted the pillow. He thrusted into the release - devoid of any human thought, now purely a dog.

And froze... His hips twitched, trying to thrust as the rest of his load dribbled forth from him. Even the peristalsis that shot his seed forth had frozen - his orgasm misfiring as he clenched into position, unable to move.

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

Hunching forward and being forced to the ground against her will as her pelvis re-structured, Adrian's brief liaison with her new genitalia was side-lined by a terror that now had her heart pounding in her chest. Feeling a tail squirming and forcing its way out from her lower back, she screamed and wretched in panic.

"Barter! Do something! Please! I don't want to... be a rfff-bitch!"

Edward's eyes blinked. Someone said his name... and spoke to him like he was human... Why? He's sat on his haunches like he was told to - paws nice and neat. Tail wagging. Tongue panting. So why? Why talk like he's a human? Because... because... he... is a ...human?

"Too late, Adrian! You're almost there now - just give in and get on all fours like the rest of us!" Tera goaded as she limped closer to the stone.

The room came into focus - Adrian... Oh god. Poor Adrian - half dog, with eight breasts and trying to fight being forced to the ground... Tera - heading for the stone - NO! Need to stop her from... *sniff* What's that... *sniff* ...heavenly smell?! *Sniff sniff* Smells like... *sniff* Nate!

Edward's nose locked onto the frozen pillow-humping Husky's scent - his dick stiffening in less than a second. It was just like a bitch in heat - just like before in the changing room! And with his long muzzle, and puffy, damp black nose - it was absolutely irresistible! Edward bounded toward Nate and mounted him without a second thought, while Adrian wailed her fear in the background.

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

There it was - wrapped in its cobalt-metal mesh and crystal clear at its centre. The stone. The key to her dreams. She would never let it out of her sight again - she'd been cocky, but no more. She couldn't afford to risk it. This stone... it was the only way she could be happy. The only way she knew to get what she wanted. She reached out a paw toward it...

"Bad dog, Tera." Edward firmly reprimanded the white Labrador as he clipped the collar he'd previously worn around her neck.

" What?!" Tera screeched, lunging for the stone in a frenzy.

Edward simply held the flailing dog back by her collar, taking in a long, deep breath as he looked down at himself and saw skin. Bare, naked skin. His own penis and balls. His feet. His hands. He was human again.

" NO!!... _Good boy, Teddy! Good dog! Sit! Sit! Let me go _!"

"That isn't going to work Tera... it's over."

"But... but why? How?!" She span around, still in Edward's firm grip and saw Nate the grey Husky - frozen in place, mid-thrust.

"Wrooff!" He triumphantly barked, the sound coming out a bit muffled as he struggled to open his jaw.

Edward held Tera at arm's length as he leant down and picked up the stone, firmly grasping it in his palm and savouring the feeling of touch without pads.

"Nate touched you - causing him to freeze and give off the scent of a bitch in heat. Adrian shouted to me for help, as if I was a human, and snapped me out of the obedience trance. I couldn't resist Nate's scent, so I touched him... well, mounted him... and became human again."

Tera's eyes peeled wide as she added it all up in her head.

"That last one was actually Nate's rule, but it sounds more poetic if I say you were beaten while playing by your own rules, right?"

The white Labrador went limp, her eyes drooping down as they glistened with regret.

"I... I'm sorry - I was just..."

"Sorry doesn't cut it, Tera."

"I know! But I was just... so lonely."

"..."

"I watched you walk past my window every night... tapping out your little rhythms and dancing - having fun all on your own... I was jealous."

"What do you mean?"

"I never could... just have fun on my own..."

"So, you had to trap other people in your sick games? Force them play by your rules? Tera... why didn't you just say? I would have kept you company."

Edward loosened his grip on the white Labrador as she coughed meekly. He waited for a moment, but no response came as her eyes stayed glued to the floor. He sighed and let go of her collar, hoisting the rule-stone up level with his eyes, between a finger and thumb.

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

Epilogue

Edward had wasted no time after regaining his human form. He immediately reversed the rule placed on Adrian, gifting the stocky jock his burly physique back and allowing him to stand on two legs once more. No man had ever spent so much time lovingly caressing their penis as he did the moment it grew back - and that's saying something. Of course, Adrian did later suggest that he wouldn't have minded another shot at finding out what the female orgasm felt like. Edward laughed it off like it was a joke - to the jock's dismay.

Next was Nate, who was returned to his human body and endured a lengthy naked hug from his friend. He could have sworn their dicks touched and everything, though he barely cared after what they'd been through - their encounters had gotten far more experimental than that while down on four paws.

In a slightly spiteful but symbolic move, Edward couldn't help but place one final rule on Nate - that 'once a year, one of Nathan's words will be randomly replaced with a bark'. Nate argued it at first - but conceded the point once Edward explained that it would be a harmless reminder, for him to trust his friends and help them as soon as they ask. He probably wouldn't have done it if he'd known that, fifteen years later, Nate would bark in the middle of the biggest job interview of his life - scuppering his chances. Hindsight.

Meanwhile, Tera posed a problem for Edward. He had always liked her, and now he knew she liked him - but he couldn't forgive her for what she'd done. He placed a few rules on her, ensuring that she would never again make any rules of her own with the stone - or risk being trapped in the body of a sloth, which is probably no fun at all, he reasoned.

He arranged it so that she would live as his dog for a whole year - her speech would be imperceptible to all but him - after which, she would regain her human form. He called it atonement, but secretly knew from her heartfelt admissions, that it wouldn't be too far from what she'd truly wanted. Once she was a human girl again, they could re-examine their relationship. Edward wasn't blind to the fact that he'd had his own part to play in the unfortunate series of events that led them to this. He looked forward to opening up to her and meeting the real Tera.

As for the rule-stone, Edward walked it up to the tallest hill in his county and found an unmarked place to hide it. In ceremonious fashion, he placed one final rule upon himself - that 'Edward will have paws until he has buried the stone and if he ever digs it up again, his hands will become paws permanently'. He used his stiff pads to bury the stone deep - shovelling dirt onto it through his legs, like any dog might; then wistfully watched as his hands returned to him, mud caked under his fingernails.
