Karma's A Bitch

It was another endless Nightmare Night of Rarity, prostrated on all fours and collared like a proper bitch, took Spike's knot while he relentlessly and mercilessly rutted her. She panted and yelped, tears of shameless joy making the mascara her master applied each day run, her pouty lips smeared in bright lipstick and dog spunk which dribbled and ran down her chin.

Udders that were so pale her veins were visible slapped and smacked under his brutal thrusts while the dog mounted her, driving his hips with such force her buttocks wobbled. She was nearly tipped forward each time he speared her. Her pastel pink nipples were fully erect under the cool breeze that whistled through the dim warehouse, and her similar colored pussy and ring of her anus puckered while she squeezed down on the vein-lined, fat red cock which spread her tunnel wide open.

Tucked away in the secluded, abandoned building, the dusty interior was lined with rows of denuded, anatomically correct female mannequins that seemed to blankly stare at them. Not that either could care, Spike reduced to a mere beast by the darkness that now suffused the world, much larger and more muscular while he bred his bitch with reckless abandon.

Sunset Shimmer padded in wearing her black fuck me boots. She wore her old costume, which she filled out more nicely than ever, her mouth twisted in a malicious smile. “Might as well get into the spirit of things,” she decided with a shrug and started to cast off her clothes starting with her leather jacket. It landed on a small table nearby where her tools waited.

She'd left the camcorder running constantly where it rested on the table, stopping in the rare moments she needed to change the film, capturing each moment of Rarity's ongoing humiliation. The magically-laced drugs mixed into her food had shattered her psyche and transformed her into a permanent bitch-in-heat. “How about we livestream this one, Rarity?”

Sunset set up the recorder like Aria had shown her. She laughed at the stupefied expression on her former friend's face, her shapely physique shifting in a sultry manner while she removed her top and skirt which she chucked too.

By now she was down to a lacy black bra that barely contained her bulbous breasts, a matching pair of lacy panties that hugged her wide hips and butt like a second skin, and of course her trademark boots which denoted her bad girl nature.

Finally she unlaced her top, leaning over so that her tits swallowed the camcorder's view, and let them fall loose with a bounce. They hung suspended and she shook them about with a cackle. Then she turned, bent over and letting her ass fill the lens, as she peeled down her underwear and bared her ass and pussy to the world. She stepped out of them, a landed a two-handed smack on her rump which jiggled. “You want this, don't you?” She spread her backside open, showing off her asshole and pinkness.

The 'good' Sunset had quite a following online. Fanboys everywhere had cried bitch tears when she and the Dazzlings had raped and murdered her Mary Sue Waifu counterpart, the feast they'd made of her immortalized by one of Aria Blaze's snuff films. Nightmare Night had twisted many humans into monsters; in her case it split Sunset into two halves and the 'evil' side won out!

Now she teamed up with the Dazzlings to seek revenge on those who had violated her soul and turned her into such a bland, milquetoast little wench who stifled herself to please polite society. Patience wasn't her strong suit. She'd kept up this charade too long. Time to show the world how much she hated them for destroying the proud, independent woman she was!

She pushed the dog bowl under Rarity's cunt, the leakage of her pussy juice and Spike's excess doggy cum drooling into it. It was her slave's breakfast, lunch, and dinner, packed with all the nutrition and protein she required. “All a growing bitch needs,” said Sunset who patted Rarity's belly which had started to swell with pups. She stopped and squeezed her hanging, pendulous udders, feeling warm milk shoot over her palms while she pinched and slapped them about so that they knocked together.

So consumed was she by the moment that Sunset failed to notice him withdraw from his bitch with a pop. Rarity panted with Spike, her well-used cunt gaping open and overflowing with his messy seed sliding down her inner thighs. His shadow fell over Shimmer who laughed at her former friend's humiliation, her face permanently warped by heat and rapture.

Suddenly the muscular hellhound rose up on his haunches and slammed his weight atop Sunset. “What the fuck...ugh,” she cried as his claws dug into her shoulders and scratched them, unable to break his hold. “Get off me, you stupid mutt!”

But the warped monstrosity wasn't satisfied with one mere bitch; he wanted to spread his seed far and wide. “N-no,” she cried in wide-eyed horror when he started to buck at her, his knot trying to batter its way inside her puffy pussy lips. She desperately tried to scramble away, unable to break his hold; and after several savage thrusts he finally found his mark.

“Nooo~” But her whines were lost when his cock finally sunk into his would-be sleeve, knotting the latest who would bear his offspring. His claws roughly molested her pendulous breasts, leaving more scratches over them. He drooled over her back with his tongue out, happily humping his hoe with somehow even more brutality than he'd constantly delivered to Rarity.

He bit the nape of her neck. Scratched down her tits and buttocks, left red marks that trailed down them. Her screams mixed with moans, her entire face burning, her cunt forced to conform to his knot's shape which spread her impossibly wide.

Wet schlicks and loud slaps sounded, her asscheeks smacking under his bucks each time he nailed his breeding toy. He continued to nip and claw at her, tears straining down her face even while she moaned and whined between her blubbering.

She shrieked in realization when he planted a paw atop her head and slammed her face down. Rarity had carried the doggy bowl before Sunset, and mixed in the same drugs that had broken her to help her alpha out. She watched Shimmer's face end up buried in an overflowing dish of soupy, salty spunk, and she was forced to choose between swallowing or drowning in it.

She held her breath long as she could while he continued to rape her silly, battering her cervix with repeated blows hammering away, until she coughed. Immediately the messy sperm filled her mouth and nostrils, sliding down her throat, some blinding her crying eyes. She was forced to drink large chunks down, the warm creamy deluge settling into her stomach and sloshing about.

With a gasp she was finally able to lift her head, mongrel cream running from it, sluicing down her chin and dripping onto her swinging and swaying breasts, dangling from her erect nipples. Her memories started to blur and bleed away, replaced by stupefying bliss as the drugs numbed and warped her mind. Soon she'd be exactly like all those slutty bimbos she despised so much, her brilliant mind forever shattered. Her gaze focused on Rarity, a painful reminder of what she would soon become.

While he grunted and growled, rutting her, Rarity lapped at her face which was fully flushed almost scarlet as her hair. Her entirety shook with each manic plunge, and her funholes instinctively squeezed down.

Despite her sobs she chewed her lower lip in attempt to restrain her moans, which grew louder as her sanity dimmed, until her lewd whimpers echoed throughout the room.

One of his paws rested atop her head and slammed it down. Her cheek connected with the slippery floor and slathered it in more splooge. With a last, hateful thrust, Spike smashed against her cervix, balls deep in his whore when he opened his maw and howled. His balls churned when his seed pumped repeatedly, directly into her uterus, her eggs swimming in a sea of his sperm.

“Please...no,” were Sunset's last words before her mind as she knew it was finally swallowed up. “Yes...more,” cried her new self, shrilly squealing in a whorish manner while she squirted over his vein-lined cock and furry testicles. She milked him for all he was worth, while Rarity playfully batted at Sunset's luscious tits, making them knock about and into each other.

Pretty soon Rarity and Sunset sat submissively before their master, each adorned with collars that read SPIKE'S BITCH. They panted in contentment.

He raised up, wrapped his claws about their heads, and wiped his dick upon their faces, smearing around his cum which they slurped up. However, the beast was far from satisfied simply with his current bitches...
