It was a perfectly normal evening for Fifi and Stella, until they heard the noises from downstairs.

 

They almost didn’t hear it the first time, not over the roaring hum of the vibrator at Stella’s clit, or the electric crackle of electric shocks coursing through her collar every time she came close to orgasm. She’d been a naughty girl, and had begged for food scraps one too many times, so master had a vibrator buzzing away at her cunt overnight to keep her from sleeping, since a sleepy girl was a dopey and obedient girl, and girls were meant to be dopey and obedient.

 

She was the one who heard it first. She was lying at the foot of Master’s bed, trying to focus on anything except the desperate need coursing through her pussy, or the sparks of pain that followed. If she approached orgasm, the vibrator was set up to sense it, and give her harsh electric shocks from her collar until her body calmed down again. It left her groggy and frustrated, head ringing with pain, and so she thought she’d hallucinated the crashing and banging from below until they happened again, and again.

Something was going on downstairs, so she sat up in her dog-cage as far as the chains tying her nipples, clit, and collar to the ground would allow, and tried to get her master’s attention the only way she knew how. She barked.

 

Girls weren’t allowed to use people words because they aren’t people. Master had taught her that too. So Stella barked, and barked. Master was lying asleep in bed a few feet away, head buried in a pair of tits belonging to Fifi, Stella’s sister. He didn’t stir. Fifi awoke instead, groggy, turning over, and realising Stella was raising a ruckus, tried to get Master’s attention too, nudging him gently with her nose. When that failed, she brushed  a hand across his cock until it stiffened.

His body reacted, but he didn’t awake. Both girl’s eyes went to the glass on the bedside table. Right, he’d taken those pills to help him sleep. They were on their own.

 

Fifi untangled herself from Master’s arms and rolled out of the bed and onto the floor, crawling over to see what Stella was raising such a fuss about. 

 

Stella looked over at her sister. Fifi was the very picture of a good girl, not to mention a good dog. She had tits larger than her head, a fat wagging tail, with red welts from Master’s belt running across it. She had a bulky collar attached by a chain to a butt-plug, nipple and clit clamps to ensure she always maintained proper posture: Her head lowered and obedient, back arched to push out her chest. There were little sensors in each clamp that could elicit a shock or vibration as punishment or reward - for example, she had rings on one finger of each hand and one toe of each foot. If it detected they were too far from the ground, she was shocked and writhed in agony until she started crawling again like a good girl.

 

She growled lowly at Stella, knowing she was being loud, naughty! The two were essentially twins, save that Fifi had pigtails and Stella had a pixie-cut. Stella was also half an inch taller, a product of her former life, and most importantly had tits a half cup size smaller, which made her the mutt of the pack. Stella stared at Fifi, shying away and whimpering, apologetic. But she had good reason for barking! Something was going on downstairs!

Fifi was half tempted to bite or punish the rowdy bitch herself until she heard another bang, and the sound of speech. She went silent at that, realising Stella was being a good girl after all. What was making all the noise? Had something broken? Was it another thunderstorm, isolated entirely downstairs? Or worst of all, the dreaded hoover?

Fifi left Stella behind to nudge the door open and go and investigate. The door had been left slightly ajar so Fifi could go piss in the night if she needed to, since bitches weren’t allowed to open closed doors on their own. She stared down the stairs, and at the bottom, saw the source of the commotion.

A man!

Excitement surged through her, and immediately her cunt started to drip. A man was in the house! She wasn’t sure what he was doing downstairs, but honestly, she was never qute sure what men were doing, she was too retarded to understand anyway. She bounced up and down, tits jiggling in excitement. She should go see him, and see if he needed her to do anything, and suck his cock, and serve him, and worship him, and-

Wait, no. She wasn’t exactly decent right now, was she? She looked down at herself. Tits out, collar on, cunt dripping, what was missing here? Something told her she couldn’t go greet him yet, she wasn’t ready, worthy, to see a man in this state, but what had she forgotten?

To bring Stella with her? Stella was a greedy bitch, and busy being punished. Fifi could surely serve this strange man alone, right? And she’d get ALL his yummy cum, and lick it all up, and let it coat her face, and-

 

Focus, Fifi. She returned to the bedroom, and Stella gave her a curious look, in between whines of pain as her clit was zapped with flashing blue arcs of electricity - she’d been close to cumming again.
Fifi stared at Stella’s face, mascara dripping down her face, and it hit her.

 

Makeup! Neither of them had fixed their makeup for the day! Fifi would go do that, and then go face the intruder.

 

Fifi rushed to the bathroom, ignoring Stella’s pleading eyes begging to be let out of her cage. Poor Stella had no clue what was going on, but Fifi wanted all the cum and attention for herself. The bathroom was the only room where they were allowed to use their hands like they were real people, with opinions and feelings and the capacity to do things for themselves. Master may know everything, but he seemed strangely hesitant to instruct them in ways about makeup, even though men just had to have better ways of doing it than her stupid women ways, like they did everything else. As a result, it was on Fifi and Stella to get themselves looking perfect each morning. He probably just had better things to do than to worry about making a pair of retarded bitches look presentable!

She reached up and grabbed the makeup box from the counter with her teeth, carefully dragging it down to the floor, and then over to the long mirror so she could see her face. As expected, her makeup was smudgy from half a night’s sleep, not that Master had given her much chance to sleep, given he was up riding her cunt until the early hours of the morning. She opened the box up, cleaned away the remnants of yesterday’s makeup and applied some new foundation, eyeliner, and of course, mascara.

She had to look perfect for the strange man downstairs, after all. Bitches were only for looking good for men, it would be bad to fail at her one and only task in life! It felt strange using her fingers to do her lashes, since they were usually bunched up into a paw, but it was a necessary sacrifice.

 

Usually Master told her what color to do her eyeshadow, and she had an array to choose from. Gold, green, blue, all to match different outfits, the season, or the occasion. But Master wasn’t here to tell her tonight. She tried to think about what the man downstairs would have wanted.

He was dressed in black, with a black… something… covering his face? He was probably a goth! Master had brought those around sometimes, men and women, to play with them. She went for black eyeshadow to match, nice and smoky. Lipstick, too. She puckered up and painted them a perfect, glossy sheen, lipstick greasy enough to leave marks anywhere she kissed. Just to be sure, she kissed the mirror, and left a perfect imprint of her lips that matched the green, red, and many, many pink ones all over the mirror. She giggled.

She was almost perfect! Now for the finishing touch. She needed to be wet, and she needed to be teary-eyed, just like how master loved her.

 

If she was found being disobedient just to make her collar shock her, she’d be punished even worse. Fortunately, next to her foundation was the perfect little tool for this. A little chilli dust, part of her makeup kit. She dabbed it in her eyes until they started to sting, red and watery, tears blurring her vision. She saw she looked perfect in the mirror, and so she simply fingered her fucktunnel until she was wet and dripping from both ends.

Now she was ready to deal with the lovely man downstairs.

 

She bounded downstairs to see him, careful to take it slow. She could quite literally trip over her melon tits on the stairs if she wasn’t careful! They brushed against the stairs every time she went down them, a little thud with each step, and if her hind legs went onto them, chaos ensued. She tried to listen to where the man was, looked left and right at the foot of the stairs, and heard him in the front room.

She crawled forward, and found him. He hadn’t noticed her, busy shoving Master’s flatscreen TV into a sack, so to greet him she bounced up and pounced him. He let out a cry of fright, raised a crowbar to defend himself, as a bouncy, eager, naked puppy-girl jumped up and nuzzled her face against his crotch, just as she’d been taught.

“Augh, jesus, what the fuck are- what?”

He was confused. She must have moved too fast, scared him! She’d been a bad girl. So she sat up onto her hind legs, hands bent forward in front of her. She arched her back to push out her titties and looked at him with big, wide, tear-filled eyes, smiling as widely and sunnily as she could, awaiting her punishment.

 

The man’s eyes bulged out of his head. He was in a T-shirt and jeans, with a bag of various valuables taken from the front room over his back. His eyes went down, drawn to Fifi’s voluptuous cleavage, and a tent formed in his pants very, very rapidly.

 

She was meant to hold still, but despite herself, Fifi wagged her tail a little. Or rather, shook her ass. He was looking! That meant she was serving her purpose of pleasing men and making as many cocks hard as possible. She stuck her tongue out, panted a little. Maybe she’d evade punishment this time?

“Jeez, I thought everybody was asleep.” He took a breath, recovering a little. Getting his bearings, as his pounding heart started to go back to normal. “You’re- christ, a puppy slut. Uh- is your master up too? Awake?” She shook her head in reply, and he settled down quickly, even ruffling her hair… and immediately reaching down to squeeze her right breast. “Okay then. I’m safe… for now. And… you… aren’t… biting or yelling or screaming…” His eyes went to the window and Fifi’s eyes followed them. The window was broken, glass all over the floor. Oh no! That was dangerous. She ought to clean that up for Master, but she had somebody fondling her tits. She decided to wait for permission to move, she’d earn a slap otherwise.

 

“...You’re just a dumb puppy who doesn’t even know why I’m here, huh?”

Fifi nodded enthusiastically! That was her! A retarded pup who didn’t know anything.

“Woof!” She agreed. He squeezed her tits even harder. He was hurting her! Tears welled up in her eyes again, and she smiled. It was so kind of him to help her refresh her makeup. She let out another bark of thanks, and shook her ass in appreciation.

 

“Good girl. And I thought all you dumb bitches were just a pain in the ass. Usually they at least bite or chase me. Okay, sit! Stay!”

She already was sitting, but she put her hands between her legs anyway, arms between her cleavage. It was so tempting to let her hands wander just a little further south, but that wasn’t the sitting position. Ass down, sitting on the haunches with knees spread, hands on the ground between legs was the way she’d been taught to sit. Even though her cunt dripped at the sight of the bulge between the man’s legs, and his authoritative tone, she knew she had to follow orders rather than do anything about it.

“Okay. Any valuables I oughta know about? Jewels or anything?” Fifi shook her head. “What about the code for the safe behind that painting in the hall?”

She bounced a little, she knew that painting! But uh, code? She tilted her head, confused.

“...What numbers. Does your master enter. To open the safe. You dumb bitch?”

She shrugged and shook her head. She was a puppy, she didn’t know numbe-

 

A thunderclap sounded as he smacked her across the face. She let out a loud whimper, pain shooting through her as she flinched, a visible handprint across her cheek.

“Retarded fucking mongrel mutt! Here!” He grabbed her by the hair, dragged her into the hall, throwing her down in front of a hole in the wall, a safe. The priceless painting that usually covered it was absent,  tossed in the man’s bag.

 

“What buttons does he press. Think hard, try to remember, or believe me I’ll make it hurt.”

 

Oh, she didn’t want it to hurt! She wanted to please the nice man. She peered at the safe, trying hard to remember.

“Your master opens the safe-” She nodded, she remembered that much. “And he pushes the buttons. You’ve seen him?” Oh, yes. She nodded and bounced up and down eagerly, panting at him. He smiled at him, she’d gotten it right! Hooray! She cheered internally, proud of herself.

“So what does he push? Do you know?”

She struggled. Tried to recall, staring at the safe. It was a keycode padlock, rows of numbers she couldn’t understand. Cogs turned and stalled in her head as she tried oh so very hard to figure out the answer. Eventually, with a blinding realization, she got it. She bounced and let out an “Arf!”

 

“...Ugh, let me guess, master told you not to talk like a person? Uh, I hereby give you permission to speak, just this once. In- in my authority as a man.” He spoke sort of tentatively, with an hesitation uncharacteristic of how Fifi thought men ought to act, but he was being so kind to let her use people-words! She was more than happy to help him.

“Okay!” She said, her voice a little ropey, emphasis on the wrong half of the word. She really wasn’t used to talking like a human being anymore, not since master had shown her she was just a dumb mutt. But she that didn’t stop her, not when it meant being helpful.

“So what does Master press to get in?”

She wagged her tail in thrilled excitement, knowing the man was going to be so proud of her for knowing this. Her piss-puddle of a brain had worked so hard on it, she didn’t think she could do it, but she did. Using all her mental might, trawling through all her beloved memories of master, she remembered the answer, and told it to the man.

“The buttons!”

 

“...”

“FUCKING!”

He hit her again. A punch to the stomach bowled her over. She whimpered, not in pain, though pain surged through her stomach. In disappointment in herself, guilt at disappointing him. He dragged her by the hair into the front room, threw her onto the couch.

“Retarded, useless, idiotic piece of- shake your tits at me, then lead me on like that and think it’s fucking funny? You thought that was fucking funny?!”

He unbuttoned his belt and she cheered up instantly. Oh, he wasn’t disappointed with her, he was going to use her. She let out a happy bark. He might be frustrated, Fifi could tell, but he was about to take it out on her, so it’s fine!

His pants dropped to unveil a huge, thick cock, but she barely got the time to drool over it before he shoved it hard into her cunt. She was wet and tight as she ought to be, and slammed her fat ass against him.

“Fucking-” He slapped her ass loud enough to let out a thunderclap. “-Apologise-” He tugged her hair so hard she could feel it tearing, like a clump had come out. “-bitch!” The pain nearly broke her, but she felt so good. Everything was so pure, so right, like she was fulfilled, living out her very purpose, as her cunt squeezed around his thick, meaty rod, and she slammed herself down on it, again and again and again.

 

“Arf! Whhf, mhrh, ohhh, ohhhh! Ohhhhh!” Her moans got more and more human as she got closer and closer to climax, and finally he came inside her tight little cunt. He seemed much less stressed now, and even if she had a burning pain in her head, her ass, and her cunt, she was happy, flopping against the bed.

 

“Fhh- fuck that was stupid, you just- staring at that fat ass got me so worked up.” He re-buckled his pants, and to Fifi’s immense sorrow, hid his magnificent rod away from her. She’d been turning around already and nuzzled at the bulge anyway, trying to get him to open it again, eventually drawing down the zipper with her teeth. Even if the belt was still in the way, sometimes-

Ah, perfect. The semi-soft dick slipped out from the gap, and she started to suck him clean, finishing her job just as she was trained to. Her eyes rolled back at the heady, musky taste of her own cunt on his cock, sending her up to heaven, and after a few seconds she released, panting for breath, tongue out and drooling all over her tits, the floor, and the man’s shoes.

 

“...Let’s just-” He shoved his cock back in his pants, barely even seeming interested in her sucking his cock. Fifi thought that was odd, but he was looking around, staring at the clock, like he was in a hurry for some reason. He slung his back over his shoulder, saying “Let’s just head upstairs, bedroom usually has jewlery and shit, and I bet he has some dumb diamond studded collar for you girls or something I can hawk at least. 

 

The man made his way upstairs and Fifi followed. Her legs were a bit shaky, and she dripped cum onto the carpeting and stairs behind him, stopping to lick it up every time. It made her take twice as long to reach the top of the stairs as him, and he grunted “Hurry up mutt” once he got sick of staring at her fat, shaking ass whilst he waited. 

 

Stella jumped up once they both came back. She barked and barked at the intruder, jumping against her cage, rattling it. She knew this man wasn’t meant to be here, and put together what Fifi hadn’t. He must be a burglar! She was always smarter than Fifi, this was why master punished her to make her more stupid, the electric shocker in her ass- she whined as the excitement rose too high, and it zapped her again - was meant to fry her brains a little, afterall.

 

The burglar jumped at her initial burst of activity, but then settled down. He saw Master in bed, fast asleep.

“Is, uh - oh lord, tell me he isn’t dead…” He grunted, poking Master with the edge of the crowbar. Fifi shook his head. No, silly, he still got a hard-on when she stroked his cock, he was alive! But the burglar put a hand in front of his lips to check for breath, and then when he saw the pill bottle, he understood.

“Oh, right. Christ, this is strong stuff.” He murmured after reading the label, putting it back down. “No wonder he’s conked out. Guess I have until morning to do the place over. Maybe you CAN suck my dick a bit more…” He tapped his chin in consideration, and Fifi bounced up onto the bed in excitement, and now she was eye-level with him, licked his face as a thank you.

“Arf, arf!”

“Ah, ah, hey, down girl!” He laughed as he pushed her down, ruffling Fifi’s hair.

He went over to the bedside cabinets after that, rifling through her. He didn’t find much there, random knick-knacks.

“Whoof! Whoof, grrrrrrrhhhh…”

He ignored Stella growling at him for the intrusion. That was master’s stuff, she wanted the nasty burglar to get away! But he waved a hand dismissively

“Oh shurrup, mutt, I’ll get to you in a minute.”

Nothing on the bedside table. He went to the closet instead, and hit paydirt. Jewelry, probably for the girls. Emerald and sapphire-studded nipple and clit rings, plus earrings, necklaces…

Even if the piercings were clearly sexual, they were still real gems. He shoved it all into the bag. Fifi giggled to herself as she saw her favourite butt-plug go in the bag. It had a shiny diamond that sometimes caught the light and shone a little spot of light onto the floor behind her for her to chase. Maybe the nice man would let her wear it soon if she kept being so helpful.

 

Stella kept growling though. She must be jealous. Fifi barked at her in annoyance, trying to tell her to shut up, but Stella just growled even louder at that. And at Fifi!

“Grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr!”

“I said shut UP! Or-”

The man finished in the wardrobe and came to look at Stella, squatting in front of her, staring her in the eyes, his eye drawing to the vibe.

“Oh, you’ve been a naughty pup, huh? What, did you pee indoors? Spit instead of swallow?” Fifi’s mouth dropped aghast. Spitting not swallowing was the direst sin a bitch could commit. Even Stella wasn’t that bad. But she just stared at him, defiant.

Okay that was a lie. Maybe defiance was the direst sin a bitch could commit. She wasn’t even jiggling her tits for him. Stella nuzzled into his side, jiggling her own to try to make up for it, distract him from his wrath at the ungrateful, retarded, ill-bred mongrel mutt that was Fifi’s sister. She pawed at his crotch, but he planted his hand on her face and pushed her away, sending her sprawling.

“Already had you. Your cunt was boring. But SHE looks fun. Collar shocks her if she tries to bite me or anything, right? She looks mad, but…”

Stella put her hands on the front of the cage, rattling it, and the man just laughed. “I’ll take your ass not your mouth I guess, don’t think the collar would react fast enough if you bit down.”

He slid open the latch on Stella’s cage, and the lust-crazed puppy just couldn’t wait to be free. She lunged forward, tackling him and sending the bag of stolen goods clattering to the ground. Fifi’s favourite dildo rolled across the floor, and she lunged for it, picking it up in her mouth. It vibrated so good, and the tip secreted just a little bit of an aphrodisiac that always drove her wild.

The man yelled as he staggered back. He knew Stella couldn’t assault a man without being shocked, but she’d been being shocked all night. The pain hardly registered, it just turned her on more, as Stella tore his belt off with her teeth, ripping his boxers apart to get at his cock. He was terrified as he was turned on, and whilst he tried to push Stella away, she bit down on his hand when he did so, willing to hurt him just for the chance to ride his cock. She thrust down onto his rod as Fifi crawled over to mount his face, dildo in her own mouth, and the two puppygirls’ eyes met, raising their hands up to grope each other’s tits, and-

 

—-----------

“And that’s the point at which you woke up?”

“No, that was hours later in the morning, they were still there.” Master answered the nice policeman, who was busy taking his statement. The man, who Fifi had been told was called ‘Burglar’, was sitting handcuffed next to the officer, covered in scrapes and bruises. Fifi hoped she could have a go with the handcuffs next, they were always super fun.

 

“So you woke up…”

“Oh, in the morning. These dumb bitches didn’t actually stop until then. I found them in the kitchen having the time of their lives. I tried to chase him out, and a scuffle ensued. That’s when he took the bite marks. A bit undignified, I know, but what else was I supposed to do?” Master put a strong emphasis on ‘I bit him’. Not that the officer seemed to notice. Stella was nuzzling against his leg, and clearly trying to resist the urge to hump against his shoe. She was luxuriating in the headpats the officer kept giving her, and pressed her tits against his leg in thanks, showing off all she had to reward him for giving her attention.

 

“No, no, I understand. Anything you can do in a fight. Well, I’ll be taking him away then. You have two lovely pups here, it seems they saved you a lot of money.”

“That they did. No chance you want a go with them, for your trouble? I’m sure the young ruffian will stay put for it. Fifi here is still almost as tight as the day I got her, and she can do some quite creative things with her tongue. Dexterity is important - I’ve been trying to train them to write degrading things on each other with lipstick held in their mouths, you know?”

The officer shook his head. “Not allowed to whilst on the job, but I might take you up on it later.” He gave Stella’s tit a firm grope, and she beamed in response. There was an audible drip as a little wetness leaked from her cunt and into the puddle of need forming beneath her on the floor from all the attention. “If you’re training tongue dexterity, have you tried having them spell the alphabet with the tips of their tongues on another bitch’s cumhole? It’s what my sister’s master does with her, heard it works wonders.”

“Arf!” Fifi announced proudly, nodding enthusiastically. She could do that! Master showed her how to do it ages ago!

“Heh, I’m way ahead of you there.. But thank you, officer. Are you all done here?”

“All done. Call us if you need anything else.” He gave one last squeeze of Stella’s assets before closing the door behind him, to drag the burglar away.

 

As the door closed, the two bimbo pups giggled and turned to master. That had been fun, what was going to happen now. Maybe walkies, or playtime? Or-

Master slapped Stella across the cheek, sending her sprawling across the floor and bloodying her nose. “You stupid fucking bitch! What the hell were you thinking, attacking the fucking burglar? You’re a cumhole, not a fucking guard dog!”

Fifi rushed up to Stella to comfort her, lick her cheek, salve the wound. Stella nuzzled back against her, into her bust.

 

“You made me lie to a damn police officer! Do you know what would have happened if they found out the bite-marks were from you?” The vein in Master’s temple bulged, he was red in the face, stalking over to Stella, slapping her again.

“Fifi, leave her. She’s been a bad dog. YOU were good, you obeyed when a man told you what to do, even if what he told you to do was malicious and evil. You’re getting to wear your favourite dildo all week.” 

 

“Arf!” Fifi jumped for joy. Her favourite dildo! She was overcome, leapt up to lick master’s face, to grind against his bulge, humping his leg in utter thankful happiness, moaaning like a whore to show just how happy she was, how wet she was at the thought.

 

But Stella was just left there whimpering. She knew she’d done bad. She thought she was saving master from having all his things stolen, but…

 

“Look, Stella.” Master knelt down next to her. He cupped her cheeks. He was getting hard at the sight of her tears, but he didn’t let that stop him. His voice softened as he stroked Stella’s hair, gentle. “I do this because I love you, okay? If anybody found out what you did, they’d have you put down. Women are meant to be trained to obey men, but it seems your training has been slipping. I’m doubling the drug regimen in your food to keep you retarded and obedient, and-” A slight sigh, as Stella awaited her fate. “I’m going to be keeping you in the punishment cage for a long, long time, until you learn to obey any order, no matter how awful.”
