Yawning loudly, Victoria heaved her eyelids open and lifted her head slightly, taking stock of her surroundings. It was Saturday morning, and she was lying not in her and Samantha’s double bed, but on the floor beside it, on her pet bed.

This was not unusual. She’d become so used to lying on the pet bed, she often did so without even being told to. Almost as if I’ve been conditioned to like it, she thought with a wry smile. Or, as if I can’t sit anywhere else without permission from my asshole girlfriend!

Victoria was naked, except for the chunky black collar around her neck. Which wasn’t much of a surprise either. She was covered by her pale pink blanket though, which had been more than sufficient on the warm June night.

What was a little surprising was that she didn’t feel any compulsion to stay where she was. Normally, when she woke up in the morning, she couldn’t get out of bed until Samantha permitted her, which would leave her feeling trapped, helpless, and (of course) horny in the meantime. At least, this was the case on days when she didn’t have to work - which she didn’t today, because she had the whole weekend free. So why would Samantha have lifted the usual restriction? At least, she thought she had.

Shrugging off the blanket, Victoria got up onto all fours and crawled off the pet bed, onto the fluffy white carpet. Well, that answers that. Bemused, she cast a glance over her shoulder at the bed, and saw the shape of her girlfriend beneath the duvet, presumably still asleep. Briefly considering waking her up to question her about her unusual clemency, Victoria smirked as she imagined Samantha immediately ordering her back onto the pet bed and leaving her stuck there for hours on end.

I’ll let her sleep in, she decided, chuckling under her breath. She sat back on her legs, kneeling up, and made to get to her feet. Instead, she found herself falling forwards again, her arms returning to their previous position. Back on all fours.

Frowning, she tried to say, “What the fuck?” But what came out instead was, “Rrowf?”

And then, as she became aware of the noise that she’d just made: “Aarf? Uff! Ruff!”

Eyes wide, Victoria’s body shook with mirth as she struggled in vain to talk or move of her own volition. Every attempt to speak English only resulted in more barks, growls and whimpers: “A-ruff! Rar-rar-rah, rargh, hah bar-rar, rap ruff!” She found she could move around on her hands and knees, and sit back on her legs, but she couldn’t stand up. She was stuck at floor level, speaking the language of a dog. And of course, because her body was out of her control, she was quickly getting madly turned on...

“Bawoo,” she laughed helplessly, bowing down and planting her face in the carpet, her hands clutching either side of her head.

So this must be why Samantha didn’t bother confining her to the pet bed. She probably wanted her to roam around and explore their apartment, get used to being a dog. A tremor went through Victoria at that thought - if this was something she’d have to get used to, it meant it would probably be going on for a while. For the whole day, maybe...

“Howww,” she whined, lifting herself back up onto all fours, and rubbing her thighs together in a futile bid to stifle the throb between her legs. She wanted to reach down - or up, she guessed - and play with her needy cunt, but her arms felt like they needed to stay ramrod straight beneath her, holding her up. If she tried to use one of them for something else, she might lose her balance and fall over!

Admitting defeat, she plodded towards the bedroom door, which was slightly ajar. She instinctively moved her face to the tiny space between door and frame, making little snuffling noises as she nudged her nose into the gap and pushed the door wide open. Padding down the corridor to their living room, she soon noticed that her hips were swaying gently from side to side, waving her butt back and forth - as if she were waggling her tail.

“Rrowl,” she groaned. Oh God - so not only do I speak and move like a dog, now I’m gonna act like a dog too?

As she reached the living room, she glanced around to see if anything was different - if Samantha had rearranged anything in preparation for the day’s shenanigans - or if she found herself responding to anything in an unusual way. Although she meant to study the room closely, she found her head and eyes darting around erratically, randomly fixing on one thing for a moment before jumping somewhere else, without really registering what she’d just seen. She growled with frustration, struggling to force her puppy brain to focus and take in the sights.

The first new thing she saw was under their dining table in the corner of the room. Gulping with apprehension, she crawled over to confirm it was what she thought it was.

Sure enough, it was a white porcelain dog bowl. But at a distance, she hadn’t been able to see that it had ‘VICKY’ written on it in big black letters.

“Rawlp,” Victoria blurted, her whole body quivering. She felt so degraded, so dehumanised. I swear, Samantha, when I get control of myself back...

She would thank her profusely, and shower her with hugs and kisses. Because, although she was loathe to admit it, she was fucking loving every second of this. And she had no doubt it would only get more fun once her Master woke up.

Looking around the room once again with her darting puppy eyes, she saw a second unfamiliar object - a little rubber pig, standing on its stubby legs next to the couch. For some reason she found herself drawn to it, manic energy flooding through her. Charging across the room as fast as she could on her hands and knees, she closed her mouth around the pale pink rubber, sinking her teeth into the chew toy. She heard a high-pitched squeak from inside it, which sent satisfying shivers through her.

Closing her eyes, she shook her head from side to side, her teeth clamped tightly around the pig toy as she waved it in the air. She flexed her jaw, repeatedly decreasing and increasing the strength of her bite on the toy, never fully releasing it. Acting of their own accord, her hands crept out from under her and batted at it a few times, as if trying to dislodge it from between her teeth. Feeling it shift, she bit harder to hold it where it was, enjoying the repeated squeaks. She lowered herself towards the floor again, resting the top of her head against the carpet, balancing herself with her back arched and her ass raised high, as she continued to swat at her new toy. Though her mouth was full, occasional muffled grunts and growls of delight could be heard.

A part of her mind was urging her to stop, to let go of the dog toy and try to resist the absurd suggestion. But the rest of her was enjoying herself too much, lost in the mannerisms of a happy, excitable puppy. And in between those two warring factions was a small, vulnerable, whimpering part of her that was getting more and more aroused by how helpless she was, at the whim of her canine compulsions.

Vicky was a puppy. She was a playful animal, running on base instinct and desire. The harder she tried to fight it, the weaker her human mind felt, and the stronger her doggy side became. Lying on her back, she kept happily chewing the toy, waving her limbs in the air above her, a paw occasionally swiping at the rubber pig to try to knock it free of her grip.

“There she is!” a familiar voice said. Rolling onto her side, Victoria stared across the room to see Samantha standing in the doorway, with gleaming eyes and a broad smile. “There’s my girl,” she continued, her tone layered with both adoration and mockery. “Having fun?”

The sudden appearance of her girlfriend startled Victoria enough that she regained a degree of self-awareness and mental coherence, and she blushed furiously. Don’t give into her straight away, she told herself as she got back up onto all fours. “Rrrr,” she replied sulkily, her voice still muffled by the chew toy, and stared at her balefully.

“Aw, don’t be like that,” Samantha chided, her grin never faltering. “Grumpy puppies don’t get to play with toys.” She gave Victoria a hard look. “Now, be a good girl, Vicky, and drop that.”

Vicky’s eyes widened, her mind suddenly empty of all thoughts, except for yes, Master. Opening her mouth a little wider, she let the chew toy drop from her teeth to the carpet below her.

“Good pet!”

Good pets obey, Vicky thought proudly. As her Master strolled into the room and sat down on the couch, Vicky gave her an eager, open-mouthed smile, allowing her tongue to dangle from her mouth, and began to pant, waving her ass from side to side. She was a good pet.

Gradually Victoria’s human mind began to return to her again, still trapped within a puppy but becoming more cognizant of herself and her ridiculous behaviour. But before she could fully regain her senses, Samantha patted her thighs and called, “Here, girl!”

Instantly overtaken by another wave of mania, she scrambled forwards, barking dementedly - “Ruff! Arf! Aroof!” - and kneeled at her Master’s feet, reaching up and putting her front legs (no, she mentally corrected herself, her arms) on Samantha’s lap. She gazed up at her, tongue hanging out and butt waggling, as she received headpats that sent pleasant tingles through her.

After a few seconds of struggle with her puppy-self, she managed to retract her tongue and stop panting. Grinning ruefully, she nuzzled her face into a thigh, to avoid eye contact with her smirking partner. But Samantha’s fingers snaked down and tickled her nose, making her yelp and move her head back into its previous position facing straight up at her, her eyes, nose and mouth scrunched up to try and keep the tickles at bay.

Cradling Victoria’s face with one hand, Samantha patted her thick blonde hair with the other. “Good morning, love,” she said softly.

“Rowrl,” Victoria replied. She felt trapped and teased, with her girlfriend’s hands and thighs surrounding her on all sides.

Samantha peered down at her, taunting eyes softening into a more compassionate gaze. “Tone check?” she asked.

“I’m good,” Victoria answered, blinking in momentary surprise to find she could speak normally again. Of course, that was what ‘tone check’ did - it temporarily paused all suggestions working on either her or Samantha, long enough for them to tell their partner whether they were OK to continue with a scene. “I’m really fucking good,” she laughed, licking her lips. “This is so hot. I can carry on, long as you like.”

“Good,” Samantha chuckled.

“I’m arrooouwl,” Victoria continued, and then burst into soft, breathy giggles as her command of the English language abruptly deserted her once more. Blushing, she buried her face between her girlfriend’s legs again. “Rowl rawrf, rroowl!”

Samantha sniggered. “Look up at me, Vicky.”

Vicky immediately lifted her head back up again, staring at her Master with wide eyes and a slightly agape mouth. Samantha grinned down at her, as her hands snuck under her chin and began to tickle her neck. Gasping and whimpering happily, the puppy girl closed her eyes and squirmed on her knees as her owner’s fingers scrabbled along her sensitive neck skin, up the back of her head, and behind her ears, moving down to her neck again and then back up. Spasms went through her body, her hind legs kicking up beneath her. Her front legs were slightly raised off Samantha’s lap, uncontrollably waving back and forth in mid-air.

You only have two legs, a voice in her head protested. They’re not ‘front legs’, they’re your arms... right?

“Good girl,” Samantha’s approving voice encouraged her. “Oh, good girl...”

I am a good girl. “Arr, rah brah, rowlph,” she spluttered gratefully. Her cunt pulsated, revelling in the praise - and the powerlessness, of course. She still knew what was going on - she knew that she wasn’t really a puppy, and that Samantha was keeping her off-balance, distracting and teasing her to keep her from showing any defiance. But she was helpless to break through the canine act, especially with the fingers dancing across her skin. She felt so humiliated, and so horny.

At last, Samantha withdrew her hands. Victoria’s head and arms came to rest on her lap again, as she panted exhaustedly. But her respite didn’t last long - her Master tapped her nose to get her attention, and then patted the space on the couch next to her. “Jump up, girl, come on!” she urged her.

“Aarf! Rarf!” More excitable puppy energy flooding through her, Vicky scrambled out from between Samantha’s legs and sprang up onto the couch, turning sideways to face her. Her tongue fell out of her mouth again, hanging freely as she watched her Master stand up and tower above her.

“Such a perfect puppy,” she tittered, admiring her hypnotised pet intently. As her stare travelled from Vicky’s head to her rear, she grinned mischievously. “Well, almost perfect. There’s just one finishing touch.”

“Browf?” Oh God, I dread to think...

Samantha held up a hand, index finger outstretched. “Stay, Vicky,” she ordered, and then turned and walked away in the direction of their bedroom.

“Rroww,” Vicky murmured, pouting and clutching at the couch cushions beneath her, waiting patiently for her Master to return. Not that she could have done anything else, with the ‘stay’ command keeping her stuck in that spot. She smiled a little, appreciating how Samantha was using her pre-existing triggers in tandem with this puppy suggestion - although using ‘stay’ was, admittedly, lateral.

After a few long minutes (which Victoria spent fidgeting on all fours on the couch, wondering if she was prolonging the wait just to mess with her), Samantha re-entered the room, now fully dressed. She held something that Victoria couldn’t see clearly at first, but it had a long, fluffy brown tail attached to it, trailing down from her hand.

A tail? “Ruff, rahff!” she laughed. She’s gonna make me wear a tail? She really is going all in on this whole puppy play thi- Her train of thought was abruptly derailed as Samantha reached her, and she finally saw what the tail was attached to. She gulped, trepidation and lust filling her in equal measure. “Rawlp.”

Smiling wickedly, Samantha began to walk to the other side of the couch, behind Victoria. “Spread your legs nice and wide, and bow down for me, Vicky.”

“Harrp.” Trembling, the puppy girl did as she was asked, bringing her head down to rest on the couch cushion, her forelegs crossed beneath her to support her weight. She spread her hind legs as far apart as they would go, one on the very edge of the couch cushion, almost at risk of slipping off the chair altogether, while the other was buried in the crease between the cushion and the back of the chair. Her ass was aimed upwards, cheeks wide apart, presenting her hole to her Master.

“Good girl. Now stay nice and still for me.”

“Relp,” was Victoria’s muffled response. This was followed by, “Ru-oo-oooh!” as she felt cold lubricant being squirted into her asshole.

“Ready?” Samantha sniggered.

Like I can tell you, you bitch, Victoria thought, smirking. But... yeah, God, do it, please, fuck. She tried to articulate all those thoughts as best she could, and the result was, “Ha raar grah, grawl.”

Taking that as an affirmative, Samantha pressed the tip of the thick black butt plug into the gap between Victoria’s cheeks, and began to ease it inside.

“Ha-awoooo!” Vicky wailed, as she felt the obscenely, fantastically huge plug push into her hole. “Wroooowl! Hooowwww...” She fought to keep still, her body twitching and bucking. Her right leg kicked up and down spasmodically. Tears and drool were pooling on the cushion beneath her face, but she didn’t care. All she could focus on was the outrageous protrusion sliding inside her.

I’m happiest when I’m full. “Howrowwwl...” As the plug settled into place, her top-of-her-voice howling subsided into whimpers and low moans. Her new tail hung between her legs, brushing softly against her thick hamstrings as it waved back and forth.

“Up on all fours again, Vicky,” Samantha ordered. Wearily, she obeyed, straightening her front legs and raising her upper body. Samantha was standing in front of her again now, beaming at her with satisfaction. “Good girl!” she cried, giving Vicky more headpats. “Good pet!”

“Rarf!” Vicky said happily, nuzzling her Master’s hand. I’m a good girl. I’m a good pet. Good pets don’t think. Good pets obey. I’m happiest when I’m full. I’m a good girl. Good pets obey... The mantras echoed around her brain, making it so hard to think clearly - to remember that she was a person, not a puppy. A part of her brain was still protesting, defiantly trying to hold onto her intelligence, her self-awareness, her humanity... But it was getting weaker and quieter all the time.

Samantha began tickling her behind her ears again, making her gasp and shudder and lift her forelegs from the couch, waving them below her like an excited T-Rex. “Oh, sweetie, I’m gonna have so much fun playing with you today,” she laughed, her tone deliciously cruel.
