For the finale everything needed to be in place. The winners of the contest would be announced in Canterlot Academy's auditorium, where the mysterious owners of the Equestrian Suicidal Girls would make their presence known. Of course with Flim-and-Flam out of the picture that would fall to the Dazzlings who were now a foursome. Adagio was reluctant to use Sunset directly in her schemes, feeling she was still too untested, but this would be the perfect test of her loyalty.

What she didn't expect was Twilight Sparkle and her little toadies to storm their way into their headquarters. Moondancer rose from her desk. “Wait! It's after hours now, we're closing!” Dash shoved her aside as they strode past her to the stairs. “Nobody's allowed up there without an appointment! Hey” she continued to call impotently.

“Sorry,” Twilight said. “But this is important.” They made their way upwards and down the hall, which was decorated in pictures of former models. Soon they reached the office at the end. Flim-and-Flam had already been sent away, but the Dazzlings were busy looking through their records, including Sunset who liked her sisters hadn't bothered to redress.

Applejack crossed her arms. “Sunset Shimmer! It's not too late, darn it! I'm sorry I was so quick to judge!”

“It's fine. You're right,” said Sunset who raised an arm to hold back Aria who'd started to go for one of her knives. “I'm every last terrible thing you think about me. I'm a monster. A traitor. The absolute worst. Time I acted true to my nature.”

Sunny shook her head. “They've been lying to you, drugging you. That whole stunt with my body? They set it up. They've been in collusion with Sombra and Flim-and-Flam for some time, all in attempt to sway you over.”

Adagio pulled Sunset close to her, stroking her hair as she held her. “I only do what I must out of love. She's our dear sister. She belongs with us. And to make her realize this truth she denied I had to take...drastic measures. Face it. She's much happier with us. Aren't you, my sweet?” She petted Sunset who's eyes watered, turning between her friends, old and new.

Sunset lowered her head. “I...I don't know.” Her head swam with confusion every time she tried to resist the Dazzlings, but Adagio in particular seemed to have quite the hold over her. “All I've done is mess things up! You should stay away from!”

“Nuh-uh! We've heard that one before,” said AJ who readied her lasso in case the Dazzlings made a move.

“We're not leaving without Sunset,” said Rainbow who took up a fighting stance.

“I suppose mere words won't cut it. Sisters! It's time we show them we stand united too!” Following Adagio's lead, Aria and Sonata began to sing with her, and while Sunset hesitated a moment seeing who their targets would be, she too joined in, her body seeming to move on its own as the seductively sweet voice escaped her to join the chorus.

Bolstered by the geodes their harmonized voices were hypnotic, further enhanced by their choreographed danced, which froze the invaders in place, some desperately covering their ears while others cried out or sang in attempt to drown out the siren song. They started to strip down, knowing their natural beauty would only make their prey more vulnerable to their seductions.

Trixie fumbled about her fanny pack, pulled out a smoke bomb, and chucked it, the orb exploding into a gray cloud that filled the office. Coughs erupted and the dance was broken once they were all obscured down to silhouettes. Fists and feet jutted out, girls wrestled to the floor, as an all-out brawl erupted within the heavy clouds.

A knife flashed in the darkness, deftly dodged by someone else. A thick desk was overturned with a crash that that scattered papers across the room. Thankfully the room didn't have sprinklers like most of the exterior rooms, or they would have went off and ruined the photos, no doubt destroying countless hours worth of hard work.

What Sunset didn't expect was her counterpart to grab her by the hand and drag her along, her eyes still stinging and her lungs burning as she aimlessly stumbled to keep up. They dashed down the hallway, nearly fell down the stairs, and passed an incredulous Moondancer, until they arrived out in the open. The moon hung suspended in the starry sky. Luckily she'd barely started to strip before the smoke bomb went off and was able to awkwardly pull her costume back into place.

Sunny looked at Inky Rose and Pacific Glow who waited at the still-running van, Tree Hugger at the wheel in case they suddenly needed a quick getaway. “Looks like Sunset needs a wake up call, and I don't think her friends can help just now. Still too much confusion and bad blood there.” She grabbed Sunset's cellphone out of her jacket and dialed a cab. “Here's the hotel we'll be at. Don't tell the others, okay?” The pair nodded. “I need some time to speak with her alone.”

Sunset rubbed her still-blurry eyes. “Don't I get a say in this...?”

Not until your head's back on straight. Don't make me knock you out. Although it would be pretty funny in a dark sort of way if I accidentally hit you too hard and...okay, the idea of you seriously getting hurt isn't funny to me at all.” She took her hand. “Don't worry. Your friends can handle themselves...I think. They certainly have numbers on their side.”

A few minutes later the cab pulled up, and the duo filed in. The driver stared incredulously at the twins, but after a double-take set off where she demanded. By this point Sunset had no idea what she was doing or why. It all seemed so surreal. She hoped her sisters wouldn't harm her old friends. She stared weakly out the window, watching the streets and buildings pass by.

“Sorry I had to bum off your credit card. Hope you don't mind.” Sunny pulled out a pack of cigarettes and a lighter she'd asked Hugs to pick up for her earlier, lighting up and taking a heavy drag. “Ah,” she moaned breathing out a ring of smoke. “It's the simple pleasures in life. I could've done anything. Been anything. If only my parents bothered to invest in me. Now I'm just a loser hoping every smoke I take will be my last. Not like you, girl. You got a wonderful life ahead of you. Don't throw it away.”

“I...want to believe that's true. You don't know how happy I was to hear you're alive. Not just because I've been carrying that guilt for so long, and wanted to say I'm sorry.” She tightened her grip so hard Sunny's hand turned white and tasted salty tears. “I've taken so much from you. Stuff I can never give back. At best you can try and make up for lost time.”

Sunny leaned her head on her shoulder. “Don't sweat it. Like I said, I never had a future. You made all these wonderful friends and did all these cool things.” She smiled sadly. “Wish that could've been me in that candy pony land...”

Normally Sunset never would've smoked, but she gently took the cigarette from her twin, taking a long puff. They passed it between them on the trip until they finally arrived. They booked a room, rode the elevator up, and settled into a plain but well-kept interior, complete with a large television. She cocked an eyebrow with a smirk. “Only one bed...?”

“Uh, I can sleep on the floor?” She shrugged.

“No, it's fine. We've basically already seen each other naked thousands of times anyhow. Speaking of which, we could both use a shower. Don't be shy,” said Sunset as she started to casually strip and toss her clothes about. “Room for two.”

Sunny watched her for a moment before she started to undress too. “Huh, I am pretty hot. I mean, you're pretty how. Whatever.” She followed her into the bathroom, the sliding glass door left open when the nozzle was fired up. They slinked under the steamy waters, grabbing a couple bars of soap, and lathering their supple flesh in suds that dripped down their curves.

Fingers brushed lower until Sunny traced a dense fiery bush that covered her pussy. “I could really use a shave. Would you be willing to help?” When Sunset furrowed her brow, she said, “Hey, think of it as shaving your own, okay? We're pretty much the same person. Well, if we'd had completely different experiences, but you know. Help a friend out?”

Sunset sighed. “Okay, I'll do it. Sit down and...spread your legs.” She flushed at her own command. Watched her twin do so, her buttocks spreading as they smooshed upon the tiles, her thighs parted wide to grant her entry. She grabbed a disposable razor, wet it down, and with her other hand squeezed shaving cream from a bottle into her palm. She spread the wide mush over her pubic hair, flushed harder when she massaged it onto the slick surface of her double's beautiful flower.

Her hand trembled a little once she placed the blade to Sunny's moist nethers, and slowly drew it across, fiery hairs falling away in clumps. “Uh, how much should I shave? Landing strip or...?”

“How about all of it. I'm feeling bold and I'd rather not hide one of our sexiest features.”

“A-are you sure?” Sunset absentmindedly pulled on a few fiery strays. “They're...cute.”

“Really enjoying the view, huh? Better be careful or you'll get lost in that wild forest.” She winked.

“Okay,” said Sunset with a fully red face. She didn't understand why this was so sexy. She'd done this to herself countless time! Sunny relaxed and smiled, the waters running into a drain near them while she worked. She placed quivering fingers on her vagina for better purchase, spread it open a bit to get a better angle, seeing pink walls with feminine stickiness connecting them.

She fumbled and nearly slipped, inhaled deep to calm herself, ashamed at how jittery she was. She tenderly brushed the razor up-and-down, sliced away more red-and-yellow hairs, until she had completely denuded her snatch. She took a moment to study it, almost licking her lips reflexively before she caught herself. She patted it a couple times. “Okay, all done.”

“Good. Want to help each other finish washing up?” Sunny smirked at her, and she gave in, not even pretending like she wasn't attracted to her anymore. Of course Sunny did her own part, flirtatiously fluttering her lashes at her. “I say embrace the magic,” she started to sing, remembering a song from Sunset's diary. “No more holding back, just let it out.”

Sunset broke in as their eyes met. “If you can take the magic, and learn a little more what it can do.” They sang together, pressing closer, to the point where their heavy wet breasts docked. “Once the magic is part of you.” She leaned in to kiss her without thinking, and Sunny returned the gesture, biting and pulling on her lip. Their tongues locked as she savored her taste.

This wasn't like the mistake she'd made behind Twilight's back. She knew Adagio wouldn't particularly care if she slept around...so long as she came home to her and put her interests first. Her head buzzed with confusion whenever she thought about her friends, old and new, her soul torn between who she'd used to be and who she'd tried to become.

She banished such thoughts for the moment, their hands wandering all across the other's body, water dripping over the floor as they gradually took this to the bed, collapsing atop bed sheets that were soon soaked as they rolled atop them. They kissed and touched their partner all over, almost forgetting where one began and the other ended. “This feels so wrong,” mumbled Sunset when Sunny sunk her mouth between her thighs. “And yet so,” she squealed. “Right!” She practically howled the word.

Sunny pushed a couple of digits into her lover, meanwhile flicking, licking, and nipping her swollen love button, alternating between the three on a whim. With her free hand she dug a finger into her asshole, taking it to the knuckle, feeling her tight hot fissure close around it with blissful contractions. “Y-you're pretty good,” admitted Sunset who massaged her still slick tits.

“I've fooled around with a few girls,” admitted Sunny when she withdrew, a mixture of saliva and pussy juice connecting her mouth and her lover's glistening snatch. “Nothing serious. Just a bit of practice before I found someone serious.”

Sunset writhed when she dove back in like her womanhood was the most delicious meal she'd ever eaten. “Y-you could turn,” she huffed. “Any,” she panted. “Girl lesbo with skills like t-that!” She threw back her head with a scream and convulsions wracked her body, her cunt convulsing as she erupted a shower of clear female cum all over Sunny's cocky reddened face.

But she didn't give her a moment's rest, Sunset's generous mounds still rising and falling rapidly with smaller sprays, schlicks sounding each time Sunny drove more fingers into her slit and rectum, small explosions of her girly excretions spattering about.

Her mind dulled with bliss until it completely went blank. Pretty soon she drifted into a peaceful sleep.

Gloom surrounded Sunset once she slept. It was like many nights in recent memory, where she would simply lay there, trapped between a state of dreaming and awareness, while a trio of mysterious figures surrounded her. Only now they made their presence known; the Dazzlings stood around her completely bare. Usually they would sing to her, whisper things into her ear, and if what Sunny told her was true, drug and hypnotize her. This time they crawled into her bed with half-lidded eyes.

Even if her body would react she wasn't certain she would stop them. They mischievously ran their fingertips down her curves, then moved to covering her in tender pecks, her body happily twisting and almost silent moans escaping her parting lips. She was a slave before their ministrations. Especially Adagio's. Aria and Sonata locked eyes with a nod, wrapped their mouths around Sunset's breasts, and started to suckle, nibble, twist, and pull on her erect nipples. Adagio slid between her thighs, parted her folds with her hands, and sunk her tongue in, exploring her deeper than she thought humanly possible.

She surrendered herself to her sisters. Lost herself in mind-numbing euphoria. Until the walls collapsed around her, and she saw the world outside, orgies spilling out into the streets amidst fires and riots. Laughter sounded from the Dazzlings, the town slowly enveloped by the siren's song, men and women giving into baser desires, fucking like mindless animals or slaughtering each other in attempt to win these Goddesses over. But to the sirens they were merely toys to be teased and exploited until they grew too banal, and they would move on, until they eventually crossed the portal and repeated the process in Equestria.

She awoke in a cold sweat, almost leaping as she rose. Sunny pushed her back down in the darkness, laying her head back upon her bosom. “Mmmm. Relax, lover girl. You have the softest, shapeliest pillows I've ever seen. Bouncy, too.” She flicked a mound and watched it wobble. She grabbed a bottle of whipped cream she'd found abandoned in the cooler, sprayed a fluffy patter onto each of Sunset's areolas, then rolled her tongue in circular motions as she licked them clean. She applied a similar portion to her pussy and a dab on her anus, lapping at those too until she'd swallowed down every last sweet drop.

“I...can't stay here. My sisters need me.” She laid a hand over her heart, twisting further and further after all their manipulations, not to mention the geode's power which warped to suit the bad girl she believed herself to be. She had feared the geodes corrupting her friends, but for someone already tainted like her? It was merely a natural extension. At least that's what she'd told herself. But she hadn't killed someone after all, had she? “I'm...so confused. But Adagio will know what to do.”

She slid from the bed and nearly tumbled onto her face, seeing the dawn was about to break outside. Picking up her clothes, she hastily slinked back into them, tuning out Sunny's protests. “They're using you! They've got you under some kind of spell! Probably have for quite some time and it was simply too subtle for you to notice! Please, listen to me!”

She shook her head and silently wept. “You're a better Sunset than me. I had it all and threw it away.” She wiped her eyes on the back of her arm. “Thanks, Sunny. It's been fun. But I can't ignore my destiny forever. I'm a Dazzling now.” She drew away from her, went running from the hotel, out into the dimly-lit streets.

She'd made her choice. It felt natural. Like her sisters proclaimed, she was the fourth siren.

Author's Notes:

Hopefully the climax will kick in with the next chapter (We'll see if it goes to plan!) although I'll most certainly do an epilogue to tie everything up!
