Under the Waves
By: Nicole Sunstone

“So, what are we doing here again?”

Aria Blaze’s slapped her hand to her forehead as she heard the blue-haired girl’s question. “Do you ever pay attention, Sonata?”

“Of course I do! But we’re so far away from where we used to live! And I’m hungry! When’s lunchtime?” she replied, her stomach growling at the thought of food.

“The reason we are here, girls.” Adagio Dazzle interrupted as they walked up the path to Canterlot High. “Is to investigate the source of Equestrian magic at this school. So far we’ve signed up for classes, got in good with the principal and had a chance to look around.”

“Didn’t she remind you of someone?” Aria asked, the image of the pinkish-white skinned principal as she stood over her desk.

“You mean like that wizardy guy that we met all that time ago?” Sonata Dusk shouted out as Adagio shot back a glare at her. Aria groaned again at the girl.

“Not him!” she hissed.

“Something about this place does seem reminiscent of Equestria.” Adagio continued, watching as two girls, one with light-green hair and the other with a sweet-swirl hairstyle, stepped into the building holding hands.

“Can’t you feel the rainbows in the air?” Sonata asked, taking in a deep breath as they entered the foyer of the school.

“Sonata, what are you talking about?” Aria sighed, before they were cut off by another student wearing a leather jacket in the middle of the space.

“Hello, you must be the girls that I was told to show around. I think I’ve seen you walking down the halls before.” the girl introduced, trying her best to show off her best smile to the new students.

“You must be mistaken, dearie.” Adagio said, holding her hand to her chest. “We’ve only just arrived at this school.”

“Thought we have heard enough singing coming from the halls.” Aria added.

“Yeah! It’s like we’re in some sort of musical!” Sonata chirped up before starting to vocalize into a song. Aria quickly nudged her in the side to silence the melody. “Hey what was that for?”

“Oh yeah, you’ll get used to that.” she replied, thinking off about how her friends had made a super popular band in the school almost overnight through the work of their talent and magic. “Oh, where my manners? I’m Sunset Shimmer. Nice to meet you.”

“Adagio Dazzle.”

“Aria Blaze.”

“Blueberry!”

Aria nudged the girl with her elbow again. “Oh, I’m Sonata Dusk!”

“Shall we continue with the tour?” Sunset asked, leading them out of the foyer. The girls reluctantly followed as Sonata began whistling her song happily.

“Canterlot High is a really great place. We’ve got clubs, we have sports, there’s these really fun events!” Sunset continued to explain, trying to gauge the attention of the girls following behind her. Adagio held her head up, continuing to look around the halls. Aria sighed and looked at everything that wasn’t Sunset. Sonata seemed very interested in what Sunset was saying, but who really knew what she was thinking.

“There’s the science lab down the hall, the computer lab is right here. The gym is through these double-wide doors. Everyone’s still getting ready for the showcase that’s gonna be this weekend.”

“Showcase? What kind of showcase?” Adagio asked.

Sunset sighed. “At this rate, it’ll just be a festival of performances going on before the Rainbooms.”

“The Rainbooms are playing here? Oh my gosh!” Sonata gushed, holding her hands up against her chest.

“Do you even know who the Rainbooms are?” Aria shot back, annoyed at Sonata as she continued to squee.

“Sure I do! We heard that one song of theirs when we were driving up here. We’re friends for life and we are happy! I wish everyone was happy! Happy happy rainbows happy!” Sonata sang, quite terribly because she couldn’t remember the song itself. Adagio and Aria groaned at the misinterpreted lyrics all the same.

“I don’t think that’s quite how their song goes. Besides, don’t even think about signing up. Vice-Principal Luna runs a strict schedule ever since the Fall Formal took a turn for the worse.” Sunset explained, leading the girls away from the gym as a certain Great and Powerful performer began doing an impromptu performance.

“Oh no. What happened there?” Adagio asked Sunset with a fake pout on her face.

“I’d rather not talk about it.” she answered, looking away from the girls.

“I smell a secret!” Sonata whispered loudly to Aria, who just brushed her off.

“This is Canterlot High’s own indoor pool! We had it installed when we received a large donation from Flithy Rich’s Big and Rich Company since his daughter attends the school.” Sunset continued as they stepped through the doors. A handful of students were diving into the water as well as just swimming around.

“Is that why it’s called the Diamond Dazzling Pool?” Aria asked, looking at the giant poster that had Diamond Tiara’s smiling face on it.

“It’s almost as if it were made for us.” Adagio commented, her eyes transfixed on her reflection in the pool.

“Ooh, can we go swimming? Can we? Please?” Sonata asked, first to Adagio, then to Aria, and finally to Sunset.

“I don’t know. Hey Soarin’! What time is open swim?” Sunset asked the handsome lifeguard with a blue-mohawk and silver swimming trunks.

“It should be in a few minutes! Surprise’s diving class should be finishing up!” he replied, blowing the whistle for the class to get out of the water.

“You’re in luck!” Sunset said with a smile as Sonata hugged her.

“Yes we are.” Adagio said, sending a bit of magic of her own against the door knob to the pool area.

“Did you girls bring your swimsuits?” she asked, noticing that none of the girls were carrying a backpack or anything.

“Nope! We never need th- Oww!” Sonata said before getting cut off by another jab by Aria.

“What she meant to say was that we didn’t know there was a pool so we don’t have the proper attire.” Adagio corrected as Sonata smiled and nodded.

“Adagio is so smart! She always knows what I’m supposed to say!”

“Right, well, I’m sure you can borrow some swimwear. You girls go and do that and I’ll be right back!” Sunset said before she ran off to the locker room.

“Do we have to?” Aria asked, itching at the back of the shirt that she had on.

“If we want to blend in, we need to not show off anything that might scare her away. I sense a lot of magic in this Sunset Shimmer. And I don’t think it’s all sunshine and rainbows.” Adagio remarked, playing with a wisp of magic in her fingers.

“Wait, we’re not going swimming yet?” Sonata asked, already stripped down to her bra and panties.

“Put your clothes back on, Sonata.” Aria groaned, looking away from the half-nude girl.

“I’m back! Oh, those look nice on you!” Sunset complimented, stepping out of the locker room in an orange and red bikini and carrying a towel over her shoulder. Aria and Sonata were wearing tight fitting rubber swimsuits with CHS written on the front of them as Adagio whisked Soarin’ out of the pool area, closing the door behind her.

“We look ridiculous.” Aria replied, having an expression of pure discomfort on her face. Sonata was the complete opposite.

“Sugoi!” she cheered, snapping the rubbery material against her body with a giggle.

“Where’s Soarin’? I thought there needed to be a lifeguard on duty?” Sunset asked as Adagio walked up behind the two girls.

“He said something about wanting to talk to a certain Rainbow Dash. Seemed to be a lot more important than looking over the pool.” she smirked as Aria and Sonata smiled at Sunset.

“Oh,” she sighed, looking slightly dejected. “Well, as long as we’re careful.”

“Don’t worry, we will be.”

Sunset smiled weakly before wading herself into the pool. Treading the water on the deep end, Adagio and her friends walked over before looking over the edge.

“Come on in, girls! The water is perfect!” she encouraged, giving a slight splash towards the edge.

“Ready?” Adagio asked as the three dived into the water in unison. Sunset watched as they swam around her in a circle.

“Wow, you girls are good! Did you used to be a synchronized swimming team?” she asked, starting to get a little disorientated by them swimming around her.

“Not quite.” Adagio said, her voice getting more melodic as she swam around.

“We have been known to swim from time to time.” Aria added, following Adagio’s lead.

“I love swimming.” Sonata’s voice slightly calmer than her usual high-pitched squealing.

“Oh, well, you’re really good.” Sunset commented before taking a deep breath and diving deep in the water. Closing her eyes, she felt a trio of waves brush past her in the deep. Opening her eyes for only a second, the dark-blue blurs of the girls’ swimsuits appeared to have a shimmering tail attached to them. She shook her head before popping back up at the surface.

“Did you all see that?” Sunset asked, feeling her heart pound against her chest. The three girls slowly popped out of the water, looking at Sunset.

“Did we see what?” Adagio asked, swimming towards Sunset as the others followed.

“I thought I saw a tail or something on you three! It must have been your ponytails or something.” she explained, noticing how close that the girls we’re getting to her. Her heart raced a little faster as she was treading the water.

“What if you did see what you thought you saw?” Aria asked, resting a hand on Sunset’s shoulder.

“That’s impossible. I didn’t see you three have a tail when you walked in.” She continued, trying to make sense of what was happening.

“I love your hair~” Sonata harped melodically as she ran her fingers through Sunset’s hair.

“Hey, what are you-” She paused, as Adagio held out her hand in front of Sunset.

“Now, you and I both know this isn’t the first time you’ve experienced something like this.” the orange haired girl explained, taking Sunset’s hand in hers. Swimming effortlessly up to her chest, Adagio led the red-and-yellow haired girl to her exposed thigh. “See, no scales or anything.”

Sunset quivered at the sensation of the silky-smooth skin of the girl. It didn’t help that Aria and Sonata both were rubbing their equally soft hands against her bare skin.

“There is certainly something magical inside of you, Sunset Shimmer.” Adagio continued, leaning closer to Sunset’s lips.

“I…” she struggled before Adagio pressed her finger against her lips.

“But is it pure? I wonder,”

Without a second thought, Aria’s hand slipped into the bottom of her bikini while Sonata’s snuck up her top, caressing a breast. Sunset moaned, hoping that no one would walk in while she was in the middle of pool.

“Your friends are magical too. We’ve seen the videos. Tell me… do you think we can get your ears and tail out of you?”

The girls pressed harder against Sunset as Adagio’s sweet voice rang inside of her ears, losing any resemblance of a train of thought. As she opened her eyes wide at the girl in front of her, a green shine appeared in her stare and all was lost.

“I think she’s had enough girls.” Adagio said, snapping her fingers. Letting Sunset go, she was no longer able to keep herself afloat and slowly fell to the deep of the pool.

Sunset managed to open her eyes from not drowning to find herself underneath a running shower head in the locker room, still in her bikini. The steam from all the showers being turned on made the air sticky and hot, but she was still unable to think clearly of how she got there.

Struggling to speak, she saw three figures in the mist from the hot water steam. The figures grew closer as a red shine appeared from their necks. As they stepped closer, Sunset recognized them as Adagio, Aria and Sonata, no longer wearing their respective bathing suits. Her marehood twitched at the sight of the three supple pairs of breasts coming towards her, along with the red shine that seemed to eclipse them.

“It’s time to wake up, Sunset.” Adagio said in her sultry melodic voice. Sunset blinked as she saw a shimmering layer of scales crawling up her legs.

“What… are you…?” Sunset asked, feeling even more turned on as her chest rose and fell.

“We’re known as Sirens.” Aria said with a devious smile, her legs going through the same transformation.

Sunset struggled to say something in response, but a spark shot through her as Sonata pressed her soft body right up against her.

“And you should be one too~” she whispered in Sunset’s ear, carefully undoing the strings of her bikini top.

Adagio leaned down, resting her hands on Sunset’s feet, carefully caressing them as she soothed her with a sweet melody. Sunset moaned as Sonata kissed at her neck, leaving Aria to undo the knot on her bottoms.

Her mind followed the wisps of magic in the midst of the shower, most of the showers drowned out by Adagio’s singing. Aria and Sonata joined into the harmony as they slowly removed her bikini, leaving her naked on the wet floor. Sunset couldn’t believe her eyes as the girls kept changing in front of her. The scales against their legs pressing up against her. Pristine crystal wings growing from their backs. And of course, the equine ears popping out of their wet hair.

She tried to shake her head away from this hypnotic dream, but all she could hear was the Siren’s song. Her breaths became short and heavy as the girls began to tend to her with their tongues as each took turns singing the melody. She wasn’t sure what they were turning her into but she felt something scratching to come out.

Sonata moaned as she rubbed her breasts up against Sunset’s arm, leaving her excited juices trickling down the back of her hand. Aria licked up the length of her arm, softly caressing her skin. And in the center of it all was Adagio, leading the show.

“What kind of Siren will you be?” she asked as her eyes shined green, letting their pendants’ power sink into Sunset. Closing her eyes, she felt her heart beat faster as if she was holding Twilight’s crown again. A dark wave of magic crept up inside of her as it bubbled to the surface. Adagio rested her hands on Sunset’s feet as she felt the magic envelope around her. She was changing into something, but it was something that the Sirens were not expecting.

The wave started from her feet as her toes grew jet-black claws. A sickly red color wrapped around her usually golden skin. The Sirens watched on in awe as they worked their magic, continuing the song.

Her hands stretched out as thick red claws grew out of them, the red skin crawling up to her shoulders and traveled down her chest. Her bust grew even larger, much to Sonata’s approval.

Shaking her head as the magical flowed over her face, her cheeks turned red like the rest of her as Sunset’s hair flew up into an inferno, flaming with passion. As the magic stood her up, the Sirens watched on as a pair of magnificent wings shot out from her back.

Opening her eyes, her once green eyes were surrounded by black, piercing into what would be the Siren’s souls as she smiled with her razor sharp teeth.

“Well, well, well, isn’t this a surprise?” Adagio smiled at the standing she-demon, ending the song.

Sunset stood in front of the three girls in her new transformed state, her mind seemingly lost to what it had once been. However, there was something familiar about this power. It wasn’t too long ago that she became this horrible monster before when she was fighting Twilight Sparkle and her friends. But feeling the magic in her claws, something felt different.

“She doesn’t much look like a Siren.” Aria commented, running her hands down her long, red-hot legs.

“Mmm, but she does look really hot.” Sonata added, leaning up to kiss her bare breasts. Sunset growled, pushing the girl away.

“What have you done?” she asked, her voice raspy and yet somewhat sultry.

“Our magic has the power to show your true nature. This is what you are inside, Sunset Shimmer.” Adagio replied, striking a pose as she stood in front of her, flaring her wings. Sunset roared and slammed her claws into Adagio, throwing the both of them against the wall of the showers in a swift dash.

“Change me back!” Sunset growled, still fighting what she could hold on from her humanity.

“You have so much power…” Adagio whispered, licking her lips as the wisps of her magic sunk deeper into the she-demon. “But all the power in the world can’t help you from our allure.”

Sunset moved her claw to strike at Adagio’s neck, causing the two other girls to stand up and be by her side.

“Don’t hurt her, Sunny!” Sonata cried, reaching for her arm.

“You’re gonna regret it if you do.” Aria added, holding her fists ready.

“Doesn’t it feel good, Sunset?” Adagio asked, unfazed by the threat of the she-demon’s claws. Sunset quivered at the statement, her claw wavering before the Siren’s neck. A flame was building inside of her. She had the power she had desired, but there was something more that she wanted. Dragging Adagio down from the broken tile wall to the floor, she pushed herself against her in a passionate kiss. Sonata and Aria watched on, relaxing from the passing threat.

Adagio rested her hands on Sunset’s back, between her demonic wings. Her whole body radiated with a spark of Equestrian magic that she had never seen before, giving off a wild and passionate heat. Just being pressed up against a being of pure desire had made her more excited than any other pony trapped in her allure. While she returned the passion of their embrace, Adagio desperately fought for the control between the two girls.

“I’ve… read about you.” Sunset growled, kissing Adagio’s neck as she softly caressed her bare breasts. “Back in Equestria. Sirens have powerful magic.”

Adagio moaned in a soft melody to respond to Sunset’s affections. Grinning evilly, Sunset stuck her claw into the Siren’s mouth and pressed against her tongue. Looking on in a mix of arousal and horror, Adagio’s eyes grew wide as a dark red magic spread through Sunset’s arm to the tips of her claw. Channeling her magic, a blazing fire sprung from Sunset’s sharp claws, searing the inside of Adagio’s mouth. A muffled scream came from the Siren’s lips before Sunset pulled back the red-hot tips of her claw.

“But you’re nothing without your voice.” Sunset laughed, standing tall as Adagio held her hands to her throat. Sonata and Aria rushed to her side, looking up at the hideous she-demon.

“Adagio!”

She tried to speak but nothing came out. The two other Sirens turned their attention back to Sunset.

“And you two.” She began, as she pointed to the girls. “You can’t do anything without your precious leader.”

Sonata and Aria looked at each before trying to restart the alluring melody, but the main part was missing without Adagio’s voice. They were indeed as powerless as she had said.

“Now then,” Sunset laughed, spreading her wings as she held the magic in her claws. “It’s time to show you just how powerful I am.”

With a snap of her claw, a thick red magic bound both Sonata and Aria to the floor, spreading their legs open to their waiting marehood. Sunset leaned down with her arms spread to graze the girls’ stomachs as she began pumping her long claw tip deep inside their open slits. The two Sirens moaned and squirmed against the magical restraints as Adagio watched on, paralyzed from the loss of her voice. Straining to sing using the magic of the pendant, she was horrified to see spurts of blood drip from her lips.

“Give it up, girlie. You’re not going to sing for a long time.” Sunset smirked as she licked her lips before pressing her mouth against Adagio’s marehood. The Siren moaned as she instinctively spread her legs open to let her slip her twisted, forked tongue deeper into her soft, pink center.

Pleasuring the three of them at once, Sunset chuckled, her flaming demonic pony’s tail swishing from her bare backside. It wasn’t long before the three girls reached their limit as the waves of pleasure washed over them. Pulling her claws out of their dripping slits, Sunset shoved the tips into their mouths, letting their hot, messy juices drip on their tongue. Sonata began to cry as she saw the long, thick claw enter her mouth, fearing the same fate as Adagio. Aria bit down on Sunset’s claw, but the thick, hard blacken tip felt nothing to the she-demon.

“Oh, quit crying!” Sunset barked, seeing the tears streaming down Sonata’s cheeks. “I’m not going to do what I did to poor Adagio here. Just start licking!”

Sonata sniffed and nodded before closing her eyes, wrapping her delicate tongue around the slick tip of Sunset’s claw. Aria did the same, finding something strangely enjoyable about tasting her own juices.

“As for you.” Sunset smiled, giving a look to Adagio as she blushed and shook from her climax. Without hesitation, the she-demon pressed her lips against Adagio’s, shooting her tongue deep down her scarred throat. The swapping of fluids stung against the open sores of the Siren’s throat, giving more pain than pleasure.

Pulling away, Sunset stood over the three girls as they panted and gasped for air. Her thoughts raced as the pendant’s spell grew stronger inside of her. The allure of having the Sirens at her will gave a power stronger than any friendship inside of Sunset. And with more power came the unlocking of new spells to a fiery she-demon.

Holding her claws to her head, her magic surged around her and then shot out towards Sonata and Aria, who had been panting on the ground after the pleasure that they had received. Focusing her dark magic, Sunset shrouded the girls with her power as they transformed into equally demonic figures like her. With a smirk on her face, she snapped her claws as two massive stallion-sized members grew out from the girls’ marehoods. Aria hissed with her new tongue as Sonata cackled evilly, using her slender claws to softly stroke her new addition.

“We’re going to have a lot of fun, girlie.”

Sunset picked up Adagio by her throat and threw her on the floor as she whistled for the two she-demon Sirens to come over, their shaft’s trembling at Adagio’s dripping slit and tight opening. Blowing a kiss to her minions, she let them position themselves to mount Adagio while she was on her hands and knees.

Aria chuckled as she grabbed Adagio’s rear, scratching her soft skin with her sharp claws. Fully under Sunset’s spell, she rubbed her trembling, hot member against Adagio’s slit as she softly moaned from the sensitive contact. Without another moment’s notice, she took her shaft in her hand and pressed it into her opening, stretching it wide with her girth. Adagio moaned loudly as she felt her Siren’s stallion-sized member press deep into her, making her climax almost instantly.

“Pitiful.” Sunset commented, pulling on Adagio’s poofy hair to tilt her head up to hers. “Cumming like that after she just put it in?”

She clicked her forked tongue as she grabbed Adagio’s breast, twisting her nipple. She closed her eyes as she moaned again, shaking her body around Aria’s massive shaft. Sunset snapped her claw again as Aria began pumping into Adagio’s quivering slit, her juices spilling all over the tip of the Siren’s member. Adagio’s tongue lolled out as Aria rocked her rock-hard shaft deep inside of her, gripping tight to her wide hips.

“You like that, don’t you?” Sunset asked, her demon tongue licking along the side of her cheek. With another snap, Sonata leaped over the two girls to position her dancing rear right up against Aria’s tight stomach. Holding her dripping stallion member on Adagio’s bare back, she stroked it softly as she rubbed her hot juices all over her shaft. She cackled as her demon-like wings flapped excitedly, licking her claw before slipping a single claw into Adagio’s tight rear. She screamed as Aria pounded into her, moaning as another climax came over her.

Sonata giggled in her evil-transformed voice as she pumped her claw fiercely into the tight opening, making it slick with her saliva. Once it felt good enough, she struggled to push the tip of her trembling member in the small, tight opening. Adagio bit her lip as her legs and arms buckled at the force being used to push another stallion-sized member into her. Soon enough, the resistance faltered as Sonata’s shaft pushed all the way in. The two Sirens rubbed together inside of Adagio as her slit dripped with more and more of her juices, sticking her rear high in the air as she moaned.

“Now, now, we’re not done yet.” Sunset said slyly as she grabbed Adagio’s chin, her tongue still panting outside of her mouth. Looking up, Adagio saw Sunset’s massive demon stallion member hanging in front of her face. Using one of her claws, Sunset held the wide shaft against her open mouth and bucked herself down into her throat. Adagio coughed as the three girls pushed themselves deep inside of her as her marehood trembled and squirted more of her love juices all over the tile floor beneath her.

Sunset’s member grew rock hard as Adagio’s tongue pressed up against it with every moan giving a soothing sensation around her shaft. Aria groaned as her breasts bounced against Sonata’s rear pressed up against her. Sonata howled and growled as she pumped faster into Adagio’s rear, her shaft starting to pulse against Adagio’s inner walls. Aria felt a similar sensation as her claws drifted to Sonata’s jiggling breasts, pulling her back into her as her wings flared out. Sunset closed her eyes as her demon shaft twitched and pulsed as the wave was coming over her.

In harmonic unison, the Sirens and Sunset moaned loud enough to break the mirrors in the locker room as their members spurt out a thick, hot juice deep inside of Adagio. Aria’s shaft filled up her slit as her own juices poured out over her wide member while Sonata’s juice spilled out of her rear. Pulling out, the mixture of fluids seeped out as Adagio’s legs collapsed. Sunset pulled her demon member out of her mouth as she fell, still spraying her hot juice all of Adagio’s face. Stroking her shaft, her tip dripped out the last of her demonic juices and with it, the rest of the magic that the Sirens had filled her with.

Adagio fell on her back, covered in Sunset’s thick juice as the demon closed her eyes, slowly transforming back to normal. With the magic receding, the two other Sirens fell into a deep sleep as they shifted back to normal. Sunset fell back against the wall as she panted, her eyes slowly shifting back to normal as she closed them, hearing the soft sound of the running shower over her head.
