Captured by the Sirens, most of the mane 6 are helpless under the sirens' lustful touch, the emotion-eating predators intending on using their sexual energies to repair their hearts. The girls' only hope lies in Twilight and Sunset, who were away when the Sirens captured them.

At gunpoint, and helpless against the superhuman strength of their captors, one thing is for sure; if the two can't do anything, their friends' fates are sealed...

Chapter 1: Captivity

Rainbow Dash stood, glaring at her captor as she led them through the forest. What were the chances the Dazzlings would be hosting a musical show near Camp Everfree just as they were visiting? Whatever the odds, it had happened, and now they were paying for it. The moment Sunset and Twilight split from the group to run some recon, everything went wrong. The sirens had found them, and… Well, even without a gun, they would have been helpless against them. It seemed they still clung to some of their otherworldly nature, as the immortal siren had barely reacted when she had tried to disarm her, Aria's strength being nothing short of superhuman. The only one of them who could possibly face one of them was Applejack, but all three? it was useless.

Soon enough, the group came across a fire-pit — the flame still roaring — as Adagio sighed and grinned, stating "Here at last… Time to get rid of some useless baggage~"

The five women paled and struggled, but among them, Fluttershy was the weakest link. Sonata shoved her forwards, eliciting a fearful shriek into her gag as she was brought closer to the flames. Each of them cried out in horror, only to tense as Sonata grasped her pants, yanked them down and threw them into the flames.

Everyone froze for a few seconds, though the sirens gained grins as the 5 women processed what had just happened. They weren't murderous, but this hardly boded well either…

"Didn't think we'd want to keep you around?" Adagio questioned with a grin, raising an eyebrow as she glanced between each of them "Each of you have magic within you. Magic which could restore our hearts… Or rather, which will~ Beyond that… I think all of us need to de-stress"

"But mostly just us three" Sonata stated with a grin, licking at Fluttershy's cheek as she began to work on her shirt. Naturally, the timid woman struggled and squealed out, but her fearful nature prevented her from doing too much to stop her, a huge blush growing over her face as she gave a squeal and uselessly struggled harder as Sonata ran a hand along her breasts, before she moved to wrap ropes around her breasts and shoulders.

—————————————————————————————————————————————
It took only a few minutes for the Sirens to… Mostly… Strip each of them. Copping a feel along the way, dipping a finger into the sexes of their captives, stroking their curves… Pinkie and Fluttershy were mostly compliant, while Rainbow and Applejack made things difficult. Though they couldn't move their arms, they kicked at any attempt to remove their pants, and managed to keep them for now. Rarity, meanwhile, had the strongest reaction to any attempt to strip her, resulting in a frantic groping and clawing effort from the sirens until her clothing was torn, exposing her most private areas.

Adagio smirked and stood, as she tugged on Rainbow Dash's leash — forcing the athlete to stumble over to her, earning a grunt and hateful glare. The others were forced to follow in various states of distress or resistance, as Adagio stroked upwards from the athlete's stomach to her breasts, massaging the twin orbs slowly and earning a moan from under her gag as she struggled and writhed — Adagio responding with a laugh as she purred "Why so angry, Rainbow Dash? You do have an excellent figure…", slowly leaning forwards as she growled "I will make sure to enjoy it in the future~", kissing the gag right in front of Rainbow's lips — earning a furious blush and outraged cry

Fluttershy, meanwhile, was trembling violently as Sonata stroked over her sides with a grin, purring "Ohhh, so hot~ So timid… Aghhhh, just makes me want to… Pin you to a tree and make you mine!", moving her hands up to squeeze her breasts — earning a shriek from Fluttershy — as Sonata cooed in a sing-song voice "Can I keeep her, 'Dagi~?", tracing her hands up to stroke Fluttershy's shoulders as Adagio rolled her eyes "Later, sure. but do remember to share."

Aria, meanwhile, frowned and lifted her gun — muttering "I don't trust this forest. Fun later. Now, let's get to the van. Link them into the rune-array we prepared, to prevent interlopers from messing us up." — Adagio groaned, but nodded as she stated "Fine! You have a point. Alright, slaves! This way!"

The yellow Siren quickly began to lead the group away, as Twilight and Sunset slowly shifted around the trees until they were confident the sirens would not see them group back together. At that point, Sunset rushed over to Twilight with a frown. "…We need to get them out of there. These three are bad news, and if they've got magic prepared… Outside help isn't going to work. We have speed on our side — let's get to that van before they do, and see if we can interfere with their runes."

"O-Okay?" Twilight stated with a grimace, fear plain in her eyes. She wasn't sure how they were going to get out of this one… And the possible outcome had just become all too real.

Chapter 2: When At First...

Sunset grinned as they had rushed ahead, the inevitable struggling of some of their friends having delayed the sirens for long enough for the pair to find the Sirens' truck. "Score!" the red-headed woman hissed, before looking to Twilight "Keep a lookout. I'll get in and turn their rune-array into a trap… If they're planning what I think they're planning, we can take them all out in one go."

"K-Keep a lookout… Right." Twilight stated with a shiver, nodding as she turned to find a good hiding space with a good view of the sirens' likely entry-point. She soon found one of her arms instinctually raising to cover her breasts, despite her current state of dress. "I hope Sunset knows what she's doing…" the purple woman thought, before maintaining her watch

"Ugh, can you BE more slow!?" an exasperated Aria Blaze groaned, turning her gaze back to a struggling and writhing Applejack, before she raised a hand and squeezed the woman's right breast harshly — painfully — pinching her nipple as Applejack gasped and gave a cry, wincing as she redoubled her struggles for a few moments, before she started to reluctantly follow the chain-gang without struggle a few moments later, shivering as she grunted under her gag, only to give a cry as Aria once again hooked a finger under her pants and tugged — kicking, though it was too late, as her last remaining bastion of modesty now hung from her knees, causing her to groan with a blush

Adagio glared "Don't look at me! This rainbow-haired BITCH isn't making things easy!" she exclaimed, yanking on said woman's leash — causing her to grunt and give a cry under her gag, straining even more and panting under her gag as one of Adagio's hands returned to stroking her breasts firmly, the Siren continuing to tug her along.

Sonata smiled and shrugged, stating "Relax… Noone's out here. We may as well have our fun, and a casual stroll works for that…", kissing Fluttershy's cheek and earning a humiliated whine from her captive, tears running down the animal-lover's cheeks as she had been the sole focus of the third Siren's attention — the pink-haired woman panting hard, before she squealed out as she climaxed over Sonata's fingers again, a small stream of feminine fluids running down her legs as Sonata's other hand kneaded her breasts, soon moving to slightly tighten the ropes constricting her breasts — the action earning another squeal from Fluttershy as the blue Siren announced "Besides. We're already there…"

The 5 humans tensed as the van came into view — Adagio giving a relieved sigh as she stated "Finally. Took long enough", quickly moving to unlock and open the door, before she purred "Come on, slaves. May as well begin your new lives now!", roughly yanking on Rainbow's leash as each of them struggled — but were, in the end, no match for her supernatural strength, soon forced into the van.

Adagio licked her lips, before she purred "I'll drive us out of here. Sonata, Aria — take your pick… I call dibs on the rainbow whore, though…", cupping Rainbow Dash's cheek and causing her to flinch back with an indignant cry as the siren detached her leash from the rest.

Aria grinned, eyeing their captives as she purred "Gladly…", her eyes soon alighting on Rarity as she gave a chuckle, and growled "This one will do nicely", putting down the gun as she groped both of the fashionista's breasts — earning a squeal as she arched her back and squirmed, Aria giving a light chuckle as she pushed a leg between her legs and began to grind it into her slit — earning a despairing moan as she hissed into her ear "If it were up to me, i'd train you until you were completely broken…Nothing but a mindless toy for my pleasure… Be thankful my sisters enjoy a bit of struggle…"

Rarity gave a whimper, before she tensed and cried out into her gag as she was tugged into a side-room, her collar detached from the others. Sonata, meanwhile, grinned and exclaimed "Fine! I'll set the orange and pink one up…", before her eyes lowered to Fluttershy and she purred "And then you and I can have some personal time while my heart heals…", earning a whine as she kissed Fluttershy on the lips through the gag, before she led the remaining three humans into a side-room

Pinkie and Applejack tensed as they saw what was to be their fate for the next few hours. A table with plenty of straps and bindings… And many, many thick vibrators among other toys. Sonata snickered, as she purred "Wow, sooo many options!", quickly chaining Fluttershy to the wall before she detached the other two from her collar, announcing "Now, you two are going to have quite the hot, steamy time together!" with a snicker

Applejack and Pinkie tensed, as Applejack blanched with a look of disgust — both giving each other a small glance, before they both cried out as Sonata tugged on Pinkie's leash to force them both close to the table. Quickly, Sonata forced Pinkie onto it on her back, and strapped down her legs and chest. The blue siren moved fast, taping egg-vibrators down onto her nipples, activating them and causing Pinkie to gasp and cry out, arching her back — before a pair of thick, rubber rods were forced into the pink woman's slit and ass, causing her to shriek out as they began to buzz violently

Applejack's eyes widened as she cried out — Sonata responding with a giggle as she stated "Oh yeah! Nearly forgot you, farm-girl! Better get used to each other's moans fast!", quickly yanking her on top of Pinkie before she forced her to lay down so that their every sensitive region pressed together tightly. Sonata quickly strapped her down tightly, before she tore off the remnants of her pants with a 'tut', and applied the same vibrators to her — earning a gasp, followed by a pleasured cry from the farmgirl, whose eyes closed tightly as her back arched.

Fluttershy trembled hard and whined — unable to tear her eyes away as Sonata sighed, before she grinned and purred "And now, time for the main event!", releasing her from the wall — but gripping her leash, earning a fearful squeal from the pink-haired woman as Sonata pressed their breasts together and finally removed her gag, before she pushed into a deep kiss, moving her tongue to lick up and down Fluttershy's. The timid woman squealed and sobbed, but didn't struggle much, closing her eyes tightly and allowing Sonata her fun as she soon felt herself pushed down on a bed, Sonata grinning as she dug a finger into Fluttershy's slit and caused her to squeal

"Now, time for you to fix my heart!" Sonata stated with a grin, inhaling as Fluttershy opened her eyes, and saw a rune array atop the bed, which quickly lit up, as the fragmented red gem floated upwards. A few moments passed, before amber sparks started jolting it haphazardly — causing the Siren to tense, as she stated "What-"

Adagio smiled and sighed, as she stated "This is the life. A van just for the three of us, engine… On…" — the siren twisted the car-key before she grinned and looked down to the rainbow-haired woman looking up at her furiously from her position tightly chained to the floor, the windows tinted such as to make her impossible to see from the outside — and the cabin itself soundproof "A rainbow-headed bitch to fondle if I get stuck in traffic…" Adagio chuckled, as she moved a hand down to squeeze Rainbow's right breast, earning an indignant cry before the siren sighed and smirked, looking back to the road "Yes, this is the--"

The truck was rocked by a vibration, and a loud BANG. The siren's eyes narrowed as she groaned, turning off the engine before she exclaimed "WHAT IS IT NOW!?" — Aria replying "NOT ME!"

After a few moments of silence, Adagio groaned and muttered "Typical…", standing before she turned to head for the enchantment room. Within, she saw Sonata and Fluttershy sleeping together, as a partially restored Siren heart floated above them.

Adagio blinked, before her eyes trailed upwards and she tensed — quickly handcuffing the timid woman's right hand to the bed, before she shouted "ARIA! THE RUNE HAS BEEN SABOTAGED!", quickly grasping the partially-restored heart as she put it on and inhaled — her eyes flashing green as she paused, before grinning "And fear pours from the bathroom… Sunset, I was wondering where my first pick had gotten to… Get out here and maybe i'll go easy on you!"

Seconds earlier:

Twilight and Sunset stood in the cramped bathroom, both grimacing as Sunset whispered "They split up!? Ohhh… Celestia, I wasn't expecting that… What do I do… Is there even anything that…"

BANG

Both women paled as Adagio began to shout, Twilight trembling heavily as she looked to Sunset fearfully. The red-haired woman tensed, looking down as she hesitated, before she whispered "…They'll know we're here, because of the fear. Twilight… They don't know about you. The stench of fear will linger here for a while and mask you. Hide in the shower, mask your emotions, and do… Something. before it's too late."

"W-What can I-" Twilight began to whisper frantically, before both of them tensed as Adagio's voice called "And fear pours from the bathroom… Sunset, I was wondering where my first pick had gotten to… Get out here and maybe i'll go easy on you!"

"There's no time!" Sunset hissed, quickly pushing Twilight into the shower as she inhaled, before she gave a weak smile and whispered "I believe in you, Twilight… Save us."

Twilight trembled, tears in her eyes as Sunset inhaled, before she stood and turned to the door with a nervous look, before she sighed and opened the door, stepped out, and closed it again.

Chapter 3: Consumation

Sunset inhaled, closing the door as she glared as Adagio and Aria. Her teeth clenched, as she tensed upon noticing the cracked red gem around Adagio's neck… Obviously her sabotage was incomplete, despite her best efforts.

"So, the rest of the gang's finally here. Nice work in sabotaging the room, could have even succeeded if Sonata didn't go for it early…" Adagio stated with a grin, casually walking toward Sunset as she added "There's no point in fighting. You don't have the… Natural strength we do." with a chuckle, finally standing in front of the red-haired woman.

"You won't get away with this." Sunset replied defiantly with clenched teeth, before she gasped as Adagio moved closer. Despite her best efforts to push the siren away, she soon found her back pressed against the door, as Adagio barely responded to the greatest force Sunset used to push at her, their breasts squishing together as their faces were inches apart. It really was hopeless.

"And who's going to stop us. 'Princess Twilight'? Ha! Wherever the portal is, we're far from it. And once we get to our home, there will be no way for her to find you."

Adagio smirked and suddenly gripped the red-haired woman's dress, glaring into her eyes dominantly, as Sunset paled and struggled harder… though it was no use, as with a single hand Adagio lifted and soon tore the dress off of her body. This earned a gasp from Sunset as the woman trembled and grimaced.

"Ohhh yes, we are going to have a lot to work with, here." Adagio stated with a sadistic laugh, immediately yanking Sunset's bra off as she moved a hand to grope at her right breast roughly. Sunset gasped as she was stripped, before she paled and moaned as she was groped hard, wincing and placing a hand atop Adagio's own as Aria smirked and stepped over, pulling down Sunset's remaining underwear without trouble.

"I am sooo going to enjoy you in the future…" Adagio growled as Sunset blushed and grimaced, pressing against the door all she could as she weakly replied "N-No!", before she gasped and gave a light gag as the siren pushed into a deep kiss, invading the red-haired woman's mouth with her tongue for a moment before she pulled back with a grin.

"This has gotten me all hot and bothered… But you won't be the one to receive my attention." Adagio stated with a grin, before she glanced to Aria "Go ahead and enjoy the slut. I want to try out the rainbow-haired slut, then we'll get moving."

Aria smirked, as Sunset panted, blushed and trembled… Before she tensed as Aria gripped her throat loosely. There was no pressure, but the threat was enough. "Right. This way, whore. Already had your friend set up in bondage, so you can get some more… Personal time." the siren stated with a grin, earning a disgusted grimace and shudder from Sunset as the siren quickly began to walk her into her room.

Inside, all forms of bindings were available, along with sex-toys and whips. A bed was visible on one side of the room, and on the other, Rarity lay in bondage. The fashionista panted with an arched back, moaning as egg-vibrators worked on her nipples and clit, her clothes now completely removed as a ball-gag filled her mouth. She tensed at the sight of Sunset, giving a defeated moan into her gag, as Aria grinned and practically threw Sunset into the bed, before disrobing herself.

Sunset grunted as she landed, grimacing before she tensed and paled as she saw Aria in the nude within moments. The red haired woman tensed, stuttering "I-Is this r-really what you want, A-Aria? P-Please, don't do this…", simply earning a laugh from Aria.

"You aren't my first conquest, Sunset. We've been on this world for over a millenium, you are just the latest in a long line of slave-girls." Aria informed her, earning a look of horror from Sunset, before the Siren practically leapt atop her, and pushed into a hungry kiss with a moan. Sunset trembled and shivered, pushing against her with a groan, as Aria soon broke the kiss and laughed, reaching under the bed as she tugged some ropes into view and purred "Enough use of those hands, whore.", before the siren grinned "You're going to look cute, all tied up…"

Sunset tensed, shaking her head pleadingly, before she gasped and moaned out as Aria began to grind their slits together, grasping her wrists and tugging them behind her back, before she started to wrap ropes around them with her other hand. Soon, she tied Sunset's hands in that position in a practiced motion, before she added a second set of ropes around her body. A rope wrapped around Sunset's breasts in a figure-8, before it was tied off, squeezing only just gently enough to not hurt. A second set of ropes attached to that one, tightly pressing the figure-8 against her body, as ropes connected them to her back, forming an X-shape behind her back.

Aria soon pulled back, grinning as she purred "Much better. Now… Where were we…", moving forwards as she again captured Sunset in a kiss, grinding their slits together harder. The Siren also took the effort to grind their breasts together firmly, as her tongue ran over Sunset's, causing the red-haired woman to give a loud moan as she grimaced and trembled, sobbing gently.

Adagio grinned and sighed, finally stepping into the drivers' area as she stated "And there's the final loose end. Now, there's noone left to save YOU.", slowly gaining a sadistic grin as she moved her hands down to pinch and tug Rainbow Dash's nipples, earning a gasp and cry of pleasure from the rainbow-haired woman as she struggled.

"Understand that, you pathetic whore? It's over. We have won. So you'd best get used to the taste of my wet slit… Because you're going to be eating it out. Every day. For years. Decades. Maybe more if we get access to the right magic…" Adagio snickered, as Rainbow panted and trembled, paling lightly.

"Now. You're going to eat me out. And if you don't do it…" Adagio placed a hand atop her partially-restored heart, her eyes glowing green "I will assault the very psyche of one of your friends. We can afford a bit of insanity from our slaves. But can you…?"

Rainbow tensed and paled, hesitating before she looked down with a grunt, ceasing her struggles as Adagio smirked and lowered her pants, replying "That's a good girl.", gripping Rainbow's chin to force her to look at her, before she lowered the rainbow-haired woman's gag and pressed her now-wet slit against her mouth. Rainbow groaned and gagged in disgust, but did reluctantly push her tongue into Adagio's slit in turn, earning a loud moan as Adagio sighed and smirked, gently fondling her breasts in turns.

Twilight trembled and panted, her head in her hands as she pressed against the shower wall. It was over. They had lost. They were going to spend the rest of their lives as lesbian slaves to… Some magical creatures from Equestria. Adding insult to injury, she wasn't even into women — she didn't think any of them were.

She needed a plan. But… The situation seemed so bad… She shivered, moving her hands protectively in front of her breasts and slit on instinct, at the thought of the scenarios running through her head.

"…There has to be a way…" Twilight whispered, hoping against hope.

Chapter 4: A Rude Awakening

Twilight remained curled up in the shower as the truck began to move, as the thin walls did not hide much from her. Applejack, Pinkie and Rarity gave pleasured and increasingly exhausted moans and cries, as Rainbow gave soft, muffled moans. Sunset was experiencing the worst of it, her moans and cries laced with disgust and pleasure, only occasionally muffled — as Aria moaned right along with her.

It was a nightmare. She could see herself there, suffering through what her friends were — perhaps in but a few short hours. But as time passed, her fear turned to determination. The sirens were distracted. Adagio was driving, Sonata was unconscious, and Aria was… Busy with Sunset. As the red-haired woman gave a pleasured shriek in a particularly powerful orgasm, Twilight realized she couldn't just sit and wait.. She needed a plan.

A few minutes later, the purple woman carefully opened the door, before she moved to sneak into Sonata's room. Within, the siren was visible sleeping with a bound, gagged and nude Fluttershy. The yellow woman moaned softly in her sleep, her face scrunched up slightly as she was obviously having a nightmare about her current situation… As much as Twilight's heart went out to her, she couldn't risk waking Sonata, so she instead ignored the sleeping pair as she looked through the room — soon enough spotting red crystal shards on the floor, ones which she recognized from her earliest field samples around Canterlot High… Could this be the source of their power?

Twilight scooped all of the gemstones off of the ground quickly, just barely done with the last one as she heard Sonata groan. The purple woman tensed, slowly backing out of the room as Sonata muttered "Wha?… What happened…?", slowly raising to look over Fluttershy's bound form as Twilight tensed and immediately moved out of the doorway, holding still with a hand to her heart and clenched teeth. Calm! she exclaimed in her mind, trying to slow her breathing as she listened to Sonata.

Fluttershy groaned, opening her eyes before they both widened and she gave a squeak into her gag, as she saw a fully clothed Sonata straddling her nude form. The memories of what had just happened rushed back to her all at once, as tears came to her eyes and she whined, even as Sonata shouted " 'Dagi? What happened?"

Twilight's heart skipped a beat as she stood fully exposed in the hallway — but luckily, Adagio didn't even look, shouting back "Sunset Shimmer snuck her way into the van. Don't worry, we took care of her. I have your heart for now, it's… Half fixed. Everything's going according to plan!"

Back in the room, Sonata sighed with a grin, before she purred "Nerve of that girl. Thought she could keep me away from a slut like you…", eyeing Fluttershy as the pink-haired woman tensed and whined, struggling desperately… But to no avail, her wrists remaining trapped behind her back as she let loose a small sob, closing her eyes as a now-nude Sonata moved to grope her breasts firmly.

Fluttershy trembled, before she gasped and reluctantly opened her eyes as she felt Sonata's upper body press down against her own. Suddenly, she felt the blue siren's left knee begin to grind against her slit, earning a loud moan from the pink woman as Sonata quickly removed Fluttershy's gag, before she pushed into a deep kiss. Fluttershy tensed and squeaked in a mixture of pleasure and disgust, as she felt Sonata's tongue push past her lips and into her mouth, slowly stroking over her own tongue.

Fluttershy moaned loudly, a huge blush growing over her face as she struggled and writhed with an arched back. It was no use however, as her breathing became faster and her heart hammered in her chest, Sonata's tongue circling her own and soaking it with the siren's saliva as two breasts rubbed against her own forcefully, even as the siren's hands groped and squeezed the bases of the poor woman's breasts. Soon, Sonata moved up to pinch, tug and trace her nipples in a rhythm, as Fluttershy threw her head back and moaned loudly in a powerful climax, her juices soaking Sonata's knee… Though the siren did not slow in her abuse.

Sonata soon panted and pulled away from the kiss, her mouth travelling to Fluttershy's right ear before she whispered "Noone's going to stop me. Face it, you're mine now. This is your future…", punctuating the end of her sentence by pinching and tugging Fluttershy's nipples pleasurably, grinding her knee into her slit with greater force. This drew a pleasured cry from Fluttershy's lips, as the yellow woman trembled and sobbed, looking away with a nod.

Sonata chuckled, before she purred "No need to make this hard on yourself…", licking over Fluttershy's ear briefly, earning a small squeak from the blushing woman as Sonata added "Pleasure me in return, and… Maybe… I won't take this any further for now."

Fluttershy whimpered, staring up at the siren fearfully before she sobbed and nodded, moving to grind her own knee against Sonata's slit even as she moaned loudly, pushing forwards into a kiss, parting her own lips to allow Sonata access as she moaned out and arched her back, giving a small sob as Sonata began to grind their breasts together more firmly, slowly and sensually stroking up and down Fluttershy's sides.

Twilight tensed and held still, holding the siren-heart shards to her breasts as she grimaced and listened to Sonata molest Fluttershy. She awaited her moment, before she finally moved back into the bathroom when she heard Sonata and Fluttershy simultaneously moan in orgasm.

Twilight trembled as she sat in the shower, and allowed herself a small sigh as she slowly relaxed, looking down upon the siren heart-shards in her hands. She had seen the rune-work the sirens had used to restore Sonata's heart, and her time as Midnight Sparkle in the past had given her certain… Revelations on the nature of magic. Perhaps… She could restore Adagio's heart, and use it to defeat them? It wasn't her first choice of solution, but at this point… She was out of options.

Grasping a set of make-up from a bathroom drawer when the moans of the sirens and her friends allowed, Twilight set to work. For the rest of the trip, she tensed and drew, even as the moans and cries of the sirens and her friends echoed around her. This could work. This had to work.

Ending 1: Just Desserts

Sunset panted as she arched her back and uttered yet another exhausted moan into the insatiable purple siren's mouth, her wrists remaining bound behind her back as the powerful woman rubbed their slits together and roughly mauled Sunset's breasts with both hands, which earned a wince from the redhead.

It felt like they had been at this for an eternity — though for Sunset, a minute of this may as well BE an eternity. Her tears had long since dried, though her disgust still burned strong. "_Probably more of Aria's saliva in my mouth than my own, right now… Twilight, if you have a plan… Please let it work. I can't bear another minute of this, much less a lifetime…" the readhead thought.

Both of them moaned loudly once more in a pair of powerful climaxes, as Aria finally pulled back with a grin. "Enjoying yourself down there, Sunslut?" she mocked, earning a defiant glare from Sunset. The purple siren chuckled, walking over to a box in the corner of the room, even as Sunset panted and trembled, struggling against the restraints on her wrists to no avail.

Aria grinned, lifting a large strap-on out of the box before she turned her attention back to Sunset and purred "I think it's time I shifted things up a bit. Sure, something more personal is fun, but I can't make you scream quite as loud by just grinding…"

Sunset panted, before she tensed and paled at the sight of the monster of a toy Aria had begun to put on. She shook her head pleadingly, as she stated shakily "Please, Aria, you don't have t"

Just then, Aria had finished strapping it onto herself, as she grinned and immediately pounced atop Sunset, forcing her into a kiss again. The redhead moaned and was forced to take it, closing her eyes and shuddering as she felt the Siren's tongue rub against hers briefly, fingers tracing her nipples as Aria pulled out of the kiss seconds later.

"Oh, I don't have to. But do I WANT to make you scream? Oh yeah!"

Sunset tensed, before she indeed threw her head back and shrieked in pleasure as the large toy pushed into her already soaking-wet sex. Two hands grasped her increasingly overstimulated and extra-sensitive breasts, squeezing them viciously as she turned to look away, uttering a hot moan as she was just in time to evade a kiss on the lips from Aria. The siren settled for kissing her on the cheek, before she captured her lips moments later anyway with a wide grin, continuing to rut her exhausted quarry into submission as Sunset moaned loudly and struggled, but climaxed moments later with a furious blush and cry.

Aria chuckled, occasionally breaking the kiss, letting strings of saliva connect their lips and fall onto Sunset's face, as she stated with one word for each time their lips parted: "Face. It. This. Is. Your. Life."

Sunset panted and gave a loud moan of despair, as the purple siren drove her to climax after climax.

Finally, after hours of driving, Adagio grinned as they finally arrived at their forest-mansion. This place was completely off the grid — their new captives would be out of reach of any help, and nothing would stop their plans for world domination. Meanwhile, by her feet, Rainbow sat and moaned, her back arched as she glared at the siren.

Her defiance couldn't last, soon melting into a loud moan as she climaxed hard, the buzzing wand which was pressed to her clit using tape continuing to torment her to no end. And as the siren turned off the engine, she tensed. If they had arrived… The true weight of their slavery would begin. Not to mention, Adagio's hands would once again be free to—

Rainbow gasped and moaned in a higher pitch into her gag, looking away and shuddering as she felt the now-familiar sensation of two hands reaching down to grip and rub her breasts, fingers quickly finding and pinching her nipples, before tracing them, drawing yet more moans from her as a red aura briefly grasped her gag and forced it down. The siren's magic had been improving at a worrying pace, soon it would be as if they had never defeated her…

Adagio grinned, as she purred "Finally here. But… It sounds like my sisters are having fun. I suppose having you eat me out one more time wouldn't be too much of a delay…"

Rainbow grimaced in dismay, but moaned as she felt the increasingly familiar, moist folds press against her lips. She hadn't forgotten the siren's threat from earlier, and so with a disgusted gag and small sob, she began to lick out her captor, wishing for vengeance…

Twilight had tensed up as the van had stopped, fearing that she was out of time. However, as luck had it, the Sirens seemed… Otherwise occupied, giving her time to complete the final components of her spell. With a nervous grin, she pressed the shards of siren-heart to her rune, which quickly lit up — a purple aura seeping from her into each of the gemstones, which quickly merged and meshed into a beautiful, red gemstone.

The purple woman inhaled, lifting it before she put the gemstone on, and immediately felt a surge of power. She now had a channel for true Equestrian magic, and with it, their freedom.

She gained a serious look, before she stepped out of the bathroom, and began to chant, weaving the natural magic of the gemstone into her voice. It took some prodding, but soon enough her voice would have a truly hypnotic effect…

Aria grinned and finally pulled out of Sunset's slit as the redhead reached another climax, her chest heaving as she trembled and looked up at her. The purple siren grinned, as she purred "Hope you enjoyed that, whore. You're going to… be…" Her voice trailed off as her eyes half-lidded, a familiar voice chanting in the background.

Sunset blinked, before she grinned and began to struggle more urgently. Twilight had done it!

Fluttershy whimpered, gagging lightly in disgust as she continued to lick Sonata out deeply. The blue siren moaned and grinned, before she blinked as a familiar voice began to chant in the background. After a few moments, she slowly rose from Fluttershy's body, earning a relieved gasp from the woman as she spat to the side.

Sonata blinked, before she began to walk slowly toward the central walkway of the van.

Adagio moaned loudly as she leaked feminine juices heavily over Rainbow Dash's tongue, before she tensed as she heard an all-too-familiar voice chanting in the background. She jumped back, as she exclaimed "Twilight Sparkle!? But she was from Equestria! She will have left by now! How!?"

Rainbow panted, but gave a defiant grin as she replied "May wanna ask her that!"

Adagio tensed and turned, just in time to see Twilight charging at her. She smirked and glared, quickly moving to try and use her far superior, inhuman strength to pin her to the van wall… But strangely, Twilight's strength went beyond her own, the woman's arms glowing purple. The yellow siren cried out, as Twilight pinned her to the ground, and Sonata and Aria walked toward her in a daze.

Twilight grinned, as she exclaimed "You two! Keep her pinned down!", Sonata and Aria both giving vacant nods as they moved over to Adagio and moved to pin her to the floor of the van, Twilight tensing as she rushed over to Rainbow Dash with a blush, exclaiming "Hold on, i'll get you out of that!"

Rainbow panted and grinned with a furious blush, moaning once more before the toy was pulled away from her and she was finally released. She did cover herself with both hands, but blushed and smiled as she stated "Not bad for an egghead!"

Twilight blushed and gave a smile of her own, as she glanced away and replied "Just… Glad to get you free. Let's free the rest of the girls, and then decide what to do with these… Sirens."

Ending 2: A new life...

Twilight had tensed up as the van had stopped, fearing that she was out of time. She began to work more quickly, trembling as she continued drawing runes onto the bathroom wall… Fate, however, had other plans in mind for her…

Sonata moaned out as she climaxed over Fluttershy one last time, panting and moaning as she pressed their breasts together and kissed the woman deeply. She then grinned, as she purred "Come on, whore. Let's get indoors, and then we can have some real fun…", pushing the gag back over Fluttershy's lips as the woman whined and trembled, but reluctantly got up as her leash was tugged, and followed Sonata into the hallway

Adagio grinned and looked down on Rainbow Dash as the athlete gave cries into her gag and struggled hard. Her slit oozed juices as the buzzing wand remained pressed against her slit, and her breasts were lightly reddened as the yellow siren casually moved to grope and pinch them firmly. "I hope you're ready for your new life…" Adagio purred with a grin, earning a glare from Rainbow as her chest heaved as she soon cried out in yet another climax. The siren merely chuckled and stood, forcing her up before she led her into the hallway

Sunset Shimmer panted hotly, a grimace and furious blush covering her face as she groaned out, the purple-skinned siren breaking yet another kiss with her. Sunset… Was a mess, girlcum covering her lips and mouth and her breasts reddened from relentless groping, as her thighs were soaked with her own feminine juices. Aria was harsh, that was for sure.

"Poor Sunset Shimmer, so pathetic…" Aria growled, before she laughed and yanked on Sunset's leash, finally getting up as the yellow woman gasped and stumbled to her feet, grimacing as the purple siren moved behind her and groped both of her breasts, pressing her own breasts to the yellow woman's back as she growled "Just remember. This is your life now…", before she walked into the hallway.

Twilight tensed as she heard them move into the hallway, and felt a pang of fear run through her, followed by horror as the 6 sets of footsteps stopped. "Do you smell that?" Adagio questioned, as Sonata hummed and stated "Smells like more fear… From the bathroom?"

Twilight heard her friends give cries, as she paled and lifted the gemstones to the rune, pressing them to it. They began to glow, magical energy crackling between them… Before they collapsed onto the ground, the rune incomplete, as the door opened and all three sirens opened the door.

All three sirens grinned down at the purple (though rapidly paling) woman, as Sonata exclaimed "Oh look! It's Twilight Sparkle! I thought she wouldn't be staying in this world…"

Aria raised an eyebrow "She's slightly different. Another one of these humans? Oh well, more for us…" she growled with a grin, prowling forwards before Adagio overtook her, the yellow-skinned Siren quickly pressing Twilight to the back-wall of the bathroom as the purple-skinned woman screamed out — only to be silenced with a kiss.

Sonata and Aria grinned as they moved to her sides, hooking their hands under her clothes before starting to force them off, as Twilight screamed and struggled. Her efforts were in vain though, as within a short minute, she was stripped nude, and her wrists were tied together behind her back, as her breasts were groped hard and a finger dug its way into her slit, Adagio's tongue rubbing against her own

1 month later

The sirens grinned and sighed, as they rested in their living room. Sonata sat on a couch with Fluttershy on her lap, smirking in satisfaction as she fingered the yellow-skinned woman, and rubbed at her breasts with her other hand. Fluttershy whined and sobbed, soon enough gasping with a squeal as she climaxed against Sonata's fingers, her back arching as the blue siren pinched and tugged on her left nipple firmly. Sonata forced her into another kiss, as the pink-haired woman shuddered and closed her eyes tightly, curling her fingers. She was helpless in Sonata's grasp, though her restraints were not physical — the siren had used her magic to increase her timidness to an incredible degree. Fluttershy could try to struggle, but… She dreaded even the thought of doing something that could upset her owner. Who knows how she would react?

The blue siren grinned and stated "Sooo… How long until we rule this planet, again? I can't wait to reshape it in our image", to which Aria chuckled — groping the breasts of the still-tightly-bound Applejack and Pinkie, who both panted and struggled with squeals of pleasure, vibrating wands stuffing their soaked slits as the siren's powerful fingers visibly morphed their breasts, digging into the flesh as Sunset knelt between the siren's legs, her tongue digging deep into Aria's slit, as she sucked on her clit and gagged lightly, swallowing yet another mouthful of her feminine fluids.

"A little over two weeks." Aria stated casually, digging her right foot deeper into Sunset's snatch, earning a pleasured gasp and squeal before the red-haired woman gave a small sob of defeat, moving a finger gently against the buzzing, weighty ring that was now pierced into her right nipple. Things really were helpless. Was this to be their fate?

Adagio grinned, looking up from her own couch which she was laying back upon. "A fair wait, but at least we have entertainment" she purred before snickering, as she continued grinding the heel of her right foot against Rainbow Dash's slit, the ex-athlete panting before she moaned out in yet another climax, Adagio's fingers pinching her right nipple firmly as Rarity grimaced and trembled with a small grunt of pleasure, her lips curled in disgust as she lay in front of Adagio on the couch with her wrists bound behind her back, reluctantly licking at Adagio's breasts in turns as egg-vibrators were stuck to the ex-fashionista's nipples in return, a large vibrating wand pushed halfway into her slit. She knew the consequences for disobedience by now… And didn't want to go through that again.

Twilight lay beneath Adagio, panting and moaning with a grimace and blush as a red, magical aura stretched and rubbed the inside of her soaked slit. Her wrists were bound, leaving her helpless to resist the siren, whose other hand was stroking and massaging her breasts between painfully tight squeezes. The purple woman's chest heaved even as her head leaned away, but in the end she couldn't escape as Adagio grinned down at her dominantly again before resuming their hours-long french kiss, wet lips pressing to wet lips as a now-familiar tongue quickly found her own, running up and down it slowly, before twisting to explore every crevice of her mouth. Twilight responded with a grimace and groan in disgust, as she gave a light sob and closed her eyes tightly, her back arching. If only she had been faster…

Ending 3: Those who play with the devil's toys...

As the van finally came to a stop, Twilight grinned. this was it. The rune matrix was complete, and she had more than enough magic… She could regenerate the heart, and even pump it full of magic to give herself a power boost.

The purple woman pressed the red gemstone to the rune, as it began to glow extremely brightly. Twilight grinned and shielded her eyes as she suddenly felt a foreign magic flood her body… Enough to give her a crippling headache, as she grunted and collapsed to her knees.

Sunset panted hotly and groaned out as she climaxed again over the double-ended strapon Aria was using to rail her slit, the siren's hands practically mauling her defenseless and increasingly sensitive breasts, often earning pleasured whines and gasps.

Aria chuckled, growling "Looks like we've arrived!" before she was interrupted by an explosive BANG which erupted from the bathroom. She tensed and sat up quickly, before she exclaimed "The fuck was that!?", even as she grasped Sunset's leash and stood, roughly yanking the yellow-skinned woman to her feet. Sunset gasped shakily as she was forced onto her shaking legs, paling as Aria pulled her along. What had happened? She could only hope it was part of Twilight's plan…

The sirens each gathered in the main hallway of the truck, glancing to each other before Adagio smirked "Looks like we had another hideaway. Let's see who it is." she growled with a chuckle, quickly moving to open the door, before she tensed up and froze. Twilight stood in the middle of the bathroom, but… Something was off. A fully restored siren's heart hung from her neck, but her eyes… Her irises were colored a pure crimson.

Sunset tensed, only to gasp and wince, her arms struggling in vain as Sonata moved to squeeze her breasts viciously, pressing up against her back. The blue siren grinned, exclaiming "Ohhh wow! Did she try to supercharge one of our hearts!? Haha, must have overcharged it so much it turned her into one of us!"

Twilight looked up at her struggling redheaded friend, who looked up at her in worry. That worry soon turned into despair as Twilight gained a grin, stepping forwards and eyeing her as she purred "The blue one is right. Whatever happened… It changed me…" she chuckled, shaking her head "I can't believe I used to be one of those pathetic creatures…"

Adagio blinked, before she slowly gained a grin and replied "In mind and body, it seems! Perhaps you would like to join us… Twilight, was it? You may be powerful… But you need training. And something to sate your appetite…" with a laugh, slapping at Sunset's ass. The redhaired woman whined, leaning back and grimacing as she stated "P-Please, Twilight… Please say you're still in there…" fearfully.

Twilight grinned and walked over to Sunset, quickly pressing their breasts together before she forced her into a firm kiss with a look of dominance and satisfaction. Sunset grimaced in disgust and horror, groaning out as she struggled, but was only able to pull back once Twilight tired of the kiss. The purple-skinned woman stepped back, before she grinned and growled "…You're right. And it would be good to have some friends who are my equals… Fine, i'll join you. Maybe I can see to making myself a new heart artificially…"

Sunset whimpered and grimaced, tears coming to her eyes as Aria grinned and tugged her into a kiss, licking over her tongue briefly before the siren pulled back and exclaimed "Good! Let's show you around the mansion…"

The three original sirens left the van, dragging along their 6 captive-audience members and closely followed by Twilight Sparkle, their newest recruit. Each Siren did of course have their favorite slave — Adagio dragged along a struggling and angry Rainbow Dash, fingering the athlete aggressively and earning pleasured cries from beneath the bound woman's gag, as the siren's other hand casually (though roughly) squeezed Rarity's right breast.

Fluttershy trembled and whimpered, sobbing and squirming as she remained Sonata's favorite, the blue siren's hands gliding over her every curve and occasionally stroking at her breasts or slit. Aria, meanwhile, had ungagged both Pinkie and Applejack, and began fingering them both aggressively before ordering them to lick at her breasts. Applejack resisted at first, though showed a pained expression as the siren hummed in response and soon shouted her surrender, moving to lick at the Siren's breast — earning a smile and small moan from the powerful woman.

Sunset trembled as Twilight kneaded both of her breasts, the red-haired woman panting and moaning loudly with a grimace as the group soon halted so Adagio could unlock the door. Twilight took advantage of the situation, grinding her knee against Sunset's slit aggressively as the red-haired woman panted and cried out, soon climaxing over her leg as she sobbed softly "P-Please say you're still in there somewhere, Twilight…"

Twilight grinned, purring into her ear "I am." Sunset's hopes raised, her eyes lighting up before Twilight continued "…Going to love forcing you to bend to my will… What to do first? Make you lick me out, stuff you to the brink with vibrators perhaps? Decisions, decisions…"

Sunset sobbed, as the group entered the woodland mansion. With nothing but untamed forest for miles around, there would be no escape. She knew at that moment that she was doomed to be the slave of those three, and whatever monster they had turned her friend into… For the rest of her life.
