Tentacles and Witches

Complete darkness suffused a drafty chamber that made Trixie's furs bristle. For all she knew days had passed. The last thing she could remember was something cold and slimy wrapping around her, pulling her into a hole in the air, and then unconsciousness had mercifully claimed her. She'd thought death had finally claimed her. However that may have been wishful thinking, as she sensed far worse was yet to come.

She was laid out on her back, upon what felt like a cool stone slab, her limbs splayed out wide and held down by something slippery at each hoof. There was an odd mixture of stenches in the air; one she made out were traces of sulfur. She tried to cast a spell only for it to fizzle out immediately, the neutralizing ring attached to her horn. Not that she was surprised. Whatever captured her obviously wanted her rendered helpless.

Torches flickered on with a whoosh. She scrunched up her eyes, nearly blinded, and almost screamed once she realized the sconces were actually the skulls of ponies. It appeared she was in some sort of gothic dungeon, replete with dusty tables lined in scientific equipment, all the way down to beakers that bubbled colorful fumes.

Shelves were lined by what appeared to be pickled organs trapped under bottles. Worse still she spotted an assortment of barbaric torture equipment which had long been banned since the Princesses came to power. The sight chilled her to the core.

"Rise and shine! I hope you're comfortable." Twilight Sparkle's voice dripped with sarcasm. No, her counterpart from that parallel world, or at least the flesh. Whatever abomination possessed her had swallowed up her soul entirely. She couldn't really see her but the voice echoed throughout the stonework.

The Necronomicon rested nearby. The heavy tome was layered in the sewn-together flesh and screaming faces of myriad victims. Its arcane secrets promised unlimited power...and warped one's spirit the further they delved in return.

"Believe it or not we're still in the Crystal Empire. Even Cadance isn't aware of its existence hidden deep below the city, so deep it almost touches Tartarus itself. Sombra prepared it to carry out his experiments...and to break in particularly unruly slaves."

Trixie looked down and noticed her entire body was lined in occult symbols. "W-what the fuck?" She shivered and strained helplessly. Would she be a mere sacrifice?

Twilight Sparkle trotted a little closer so she could have a better view, her eyes hidden behind thick glasses, her mane primly tied in a ponytail, and shrouded in a somewhat tattered lab coat stained in splotches of blood and who-knows-what-else.

"Nopony knows you're here. In other words, nopony is coming to save you, and I can do whatever I like!" She produced a rusted scalpel and Trixie voided her bladder on the spot. "Pathetic. Look at you, blubbering there like a newborn. I doubt anypony will even miss a total bitch like you. And if they do you're easily replaced. Say a changeling or a lookalike mare under a glamour, once I've taken control of their minds?"

She cantered around the dungeon turned laboratory, obviously relishing her villainous monologue. "Females exist to be bred. That's your entire purpose. Now you'll be among my breeding machines. I wonder, how long will you be able to last?"

Trixie continued to twist in her bonds. "You're female, too!"

"Only this shell I've taken. Not that I think any better of males. They merely exist to mindlessly spread their seeds. Base animals driven purely by instinct. I'll transcend them all, ascend to something beyond even a God." Her crazed eyes lit up.

"You're a complete monster! You're pure evil!"

She cackled hysterically. "Silly fool. Good and evil? There is only the will to power. You can't imagine the things I've seen. Take a closer look at your bindings."

Trixie twisted her head to one side and noticed the slimy sucker-covered tentacles that held her down. "Oh Celestia..." She'd heard rumors about such eldritch abominations; and worse what they would do to a helpless mare. So they weren't myths after all.

A stray tentacle rose up between her spread legs, hovered a short distance away from her vulva, its tip already dripping precum. "N-no...y-you can't be serious!"

"Why not? I certainly don't share your moral scruples. Plus as a scientist I'm dying to see what kind of creature you'll produce once its inseminated you. That's assuming you survive the birthing process, or even the rather intense mating ritual. You're nothing more than meat to this beast. A series of holes it wishes to stuff and empty inside."

Trixie squirmed as the slippery tentacle pressed itself upon her slit and started to rub up and down. To her shame her nethers convulsed in a pleasant manner. "I-I'll stop you!"

"And how do you intend on that? You can't even protect your own foalhole!" She stroked her pet tentacle monster. "You may enter her at will. Be as rough as you like. But don't kill her...yet. After all, I'm not certain your other victims will survive your invasions."

Trixie's lips quivered as she blubbered and blinked back tears. "O-other victims...?"

Hidden compartments in the stone walls twisted with a heavy creak, until they turned entirely to reveal a series of mares like her that lay bound. Most of them were unfamiliar, but she stared wide-eyed at her own counterpart from the parallel world, likewise covered in demonic runes. Their bellies were swollen in pregnancy.

"W-who are they...?"

"Does it really matter? But I suppose I'll humor you, simply because it amuses me. Of course you recognize your counterpart from my world, but on that world she has a couple of bandmates I decided to take with me. Lavender Lace and Fuschia Blush, I believe? Sadly they broke so quickly I barely even knew them." The mares appeared to be completely vacant other than a constant euphoria which numbed their minds.

Trixie didn't even know them and yet wept anyhow, like she'd somehow lost a couple of old friends. "You...you damned-fucking-cunt-piece-of-shit-bastard-bitch-asshole-"

Another tentacle rose up and she was cut off with a "Mmmph," as it forced itself into her snout. She attempted to bite down on the rubbery appendage but found it was infinitely more sturdy than she could have imagined. Not only that but it forced itself deeper into her throat in retaliation, a thick bulge visible in her neck as she openly blubbered.

"Language. Starswirl the Bearded liked to litter my world with refuse from Equestria, such as this trio of sirens. I decided to alter them into mares however since I think they look far more aesthetically pleasing this way. Adagio Dazzle, Aria Blaze, Sonata Dusk. Small-time villains who nopony will miss. But at least they make nice broodmares."

The troika of mares were particularly sensual, their minds utterly shattered like her bandmates. Even if they were villains nopony deserved a fate like this.

Twilight pulled down screen on one of the walls, placed a projector on the table, and turned the device on. The filmstrip turned with a rattle and cast a huge movie that flickered to life. She saw her counterpart in human form, splayed naked on a table like her, a speculum inserted into her vagina and spread so wide her cervix was visible. She was soaked so wet it dripped over her clenched asshole and her perky breasts heaved.

"Not how she wanted to celebrate her eighteenth Birthday, I'm sure. She was a virgin before I started in on her....well, aside from fooling around some with her bandmates. I suppose Trixie's a bicurious little trollop in any dimension."

Trixie couldn't help but pity her counterpart; maybe she was the narcissist others claimed. To her shame seeing herself in such a vulnerable position turned her own. Her marehood winked and lathered the tentacle that lashed her labia in marecum.

Her human version was certainly odd-looking but harbored her own unique beauty. it's a shame she had to see it violated before her eyes, a series of tentacles rising around her shapely yet thin frame, and she screamed as they burrowed into her open holes and started to violently violate her. She squirmed and thrashed haplessly.

Whoever held the camcorder who'd filmed this perverse movie panned around to her cute bandmates, who were placed in similar compromising positions, only to be savagely ravished in much the same manner. They wept as tenctacles pistoned in-and-out of their mouths, pussies, and assholes with such brutality and rapidity she wasn't surprised they'd broken. This went on for several minutes until they were cummed in.

The appendages withdrew in a slimy mess, and the victims basked in their afterglow, whatever pain and fear they felt soon transmuted into pleasure. "The semen emitted by these aliens acts as an aphrodisiac that opens up a female's cervix and allows the sperm to better invade their uteri. What use is meat that refuses to be inseminated?"

The movie continued with a cut to the sirens who were likewise ravished into submission. They managed to last a little longer, shrieking and thrashing and cursing like wild animals; but after they were unloaded into twice they too broke, fucked silly with eyes rolled into their heads, and twisted into happily borderline retarded expressions.

Trixie whimpered as she came hard. She hated to see them so abused and violated but her flesh responded anyhow. By now the tentacles, which had shown a surprising amount of restraint, decided to force their way into her lower entrances. They burrowed and squirmed with a squish deeper than she'd ever been penetrated before. So deep she could feel her cervix pried open as a series of smaller tentacles invaded her womb.

Another pair arose, wrapped around her breasts, and placed mouth-like suckers on her erect nipples, pinching, pulling, sucking, nibbling on them in an almost playful manner. She hated to admit it but none of the dicks she'd ever taken compared to this.

Guilt overwhelmed her at a thrill unlike any she'd ever experienced engulfed her entirety. The rape itself she could endure. Just lie back and think of Equestria. What truly terrified her was that once they started cumming into her she'd have her psyche torn apart. She'd happily surrender once her mind was broken and be reduced to nothing more than a disposable fucktoy. She flushed bright and squirted and openly wept under a series of conflicting emotions and sensations.

Ah...look at you squalling like a foal. So pathetic. I think letting them break you would actually be a mercy. Why should I reward you with unearned enjoyment? However, I know my cute little pet has terrible needs..." She patted the witch's belly.

Trixie watched in wide-eyed horror as part of the tentacles bulged like an overfilled hose, realized it was a cluster of packed in cum, which rushed ever closer, ready to be fired into her within seconds. She thrashed in insane desperation amidst muffled cries and sobs. She'd much rather die than have her personality swallowed up whole.

With a muted scream she felt the bizarre coils unload hot sticky cum into all three of her slippery funholes. She continued to shriek and weep the entire time, even as her hips bucked instinctively, her entrances clenching as she squirted more-and-more.

They continually oozed into her. She mewled submissively as her belly started to inflate from the excess. The monstrosities had reduced her to little more than a cumdump that would put the trashiest porn stars to shame. Her stomach ballooned from the copious amounts of semen pumped into it. It sent subtle vibrations throughout her interior which made them pleasantly convulse and helped her cum even harder multiple times.

Twilight Sparkle continued to rub the witch's torso. "What a whore. I think she's endured enough for now. Withdraw." The abomination did as commanded, and when they withdrew from her fuckholes, hot splooge oozed out in dense milky rivers.

To her surprise Trixie's sanity remained intact. She wanted to curse her but by now was cowed. "P-please," she murmured with a trembling lip. "N...no more. I'll do whatever you want. I...I'll be your bitch. Just don't erase who I am. I...I'd sooner die."

She slapped Trixie's teats and the mare bowed her head in submission. Behind her the still unsatisfied tentacles started to work on the other broken slaves. They wrapped up the sirens and her bandmates, wormed their way into their hollows, rapidly entered-and-exited. "Hmm...maybe you can amuse me in another way?" She raised the scalpel, and the witch started to shudder hard, only to breathe a sigh of relief when it was tossed aside with a clatter. "You're far too easy. I think you've earned a small treat."

The tentacles that bound Trixie flipped her over onto her still somewhat inflated belly. She winced but didn't dare complain. Twilight Sparkle positioned herself upon her shapely back. Her hot breath whispered in her ear, "You remember that time you thought Twilight turned a mare into a stallion? Well, I found a spell that's pretty close."

Trixie's eyes widened anew as she suddenly felt a stallionhood start to unsheathe between her shapely buttocks. Precum dribbled down her asscrack.

"You wouldn't believe the kinds of forbidden spells locked away in the Necronomicon! Admit it. You could cut through the sexual tension between you and Twilight Sparkle. A part of you would love to get banged senseless by her. Failing that, you decided to spread your legs for her brother instead, turned on by the idea she'd be jealous!"

"That's ridiculous! I-I'm not like that..." She pondered whether the Necronomicon allowed its owner to gaze into another's heart. After all it seemed to have so many unknown powers. It was likely all the weird science that had popped up recently was a result of that. The Princesses unknowingly aided in the spread of its corruption, as they relied heavily on the experimental potions concocted and spells weaved by this monster.

Twilight rubbed the cock between her slave's flanks. "You want this buried within the Great and Powerful ass, don't you?"

"Gross," muttered Trixie who couldn't believe its size. She felt it prod around her ponut, then her pussy, toyed with which hole in wanted to enter first.

"Liar. I can smell the fresh musk of your marehood from here. Well, that's enough foreplay." She smacked Trixie hard on the butt which jiggled about and now had a red hoofmark on it. "Please me and I promise not to let the tentacles break you."

The meatstick rammed balls deep hard up her ass. Just as quickly it was withdrawn, only to be reinserted in her cunt, her cervix struck under the impact. It was a bit painful but still rather enjoyable in its own way, and rather than hold back her moans, Trixie let them fly free whorishly, desperate to please her master in any way she could. Better to become her somewhat willing toy than end up losing all sense of who she was.

An hour passed while she simply laid there in submission, moaned and whinnied, able to see the other mares be worked over tirelessly by the tentacles, who seemed insatiable no matter how many times they came inside their victims. She barely noticed when Twilight hilted in her a final time and sprayed her love tunnel in copious foal batter.

This was her life now. Just survival at any cost. There weren't many ponies who cared about her. Certainly there were many who tolerated her, or pretended to be nice for the sake of politeness, but actual friends? She had precious few of those.

"I'm sorry Celestia...I'm sorry everypony...I never meant to be a bad pony. I take back all the horrible stuff I've ever done." But only her abuser heard the whispered confession.

A cackle sounded across the lab aimed at the latest broodmare that had been broken in.
