Sunset gets seduced by two special sirens.

"You could really get lost in that song..."

There was no noise to be heard other than the sound of soft waves hitting the sand; perfectly peaceful. Those were the shared thoughts of Twilight and Sunset Shimmer as they threw down some towels onto the warm beach. It was crazy to think that anyone had yet to find this particular spot. Sure it was near some large rocks on either side of the sand bar but that also helped to add some protection, a nice reprieve from prying eyes. Twilight quickly set up an umbrella, adjusting her sun hat as she looked over at her book, excited to enjoy some quiet time reading on the beach. A quick check at her one piece bathing suit to make sure there wasn't any sand on it and soon she was laying down, letting out a content sight.

She was really glad to be visiting again and without any crazy villains to get in the way this time. She had an ulterior motive for being here but that was for later. For now, it was all about taking in the lovely beach atmosphere and getting away from her duties for awhile.

Sunset stood nearby, currently dressed in a red bikini top and short shorts. She glanced around near the rocks, having sworn she had just seen a large fish tail for a brief second. Looked way to big to be anything that should be this close to shore though. Maybe just a dolphin that got too close to the rocks while playing? Or maybe something else... Either way, with Twilight content with her book, now was as good a time as any to go do some swimming.

"I'm gonna go take a dip near the rocks, are you good here?" She asked, looking back at her friend.

"I got my book, snack and water. Yeah I should be fine. You go enjoy your swim." She gave her a look, a smirk, that caused Sunset to do a double take. Only to remember the original reason both were there in the first place. Sure, sand and sun was nice but there was something they had planned to look out for. But surely that could be put on hold, at least for now.

Sunset nodded, soon making her way nearer to the where the waves were. She stood near them, watching the ocean splash against her bare feet and looking out towards the blue horizon. As she did so, three pairs of eyes watching from the nearby rocks.

Three sirens hid behind a large rock, watching their prey. Their tails swished back and forth absentmindedly as their webbed hands stuck to the rock. They looked almost like mermaids to the casual observer. Upon closer examination, some things like their incredible beauty or gills would only confirm this to most. But they were far from simple mermaids, they are sirens and their taste of love and lust drove them on more than anything else. A purple haired siren eyed the woman with the sunhat laying on the beach, licking her lips. "I call dips on the one-piece sexy nerd!"

The dirty blond fluffed up curly haired one next to her grinned. "That's fine, I have a good feeling about the red haired swimmer. Sonata, you are with me, my instincts tell me I am going to need your special tool for this one."

The blue long haired one next to her shivered. "Oh yes, I like the look of this one, this is going to be so much fun!"

The dirty blond haired siren turned to the purple one next to her. "Try not to go too crazy Aria, remember, we are supposed to be keeping a low profile."

She rolled her eyes. "Oh please, give me a little credit Adagio, just because I drained a bit to much that one time..." She sighed, already knowing the stern talking she was going to get by bringing that incident up again. "Yeah before you start, I got it. I'll keep a close eye on her and not take too much." She let out a loud sigh.

Adagio gave her a hard glare but nodded.

The purple siren glanced back at her prey, already devising just how she plans to seduce them. Despite their appearance, she couldn't help but notice how the human seemed to shift in a such a way to look all the more tantalizing. The way her legs seemed to cross as her finger slowly dragged across her mouth before turning the page. Might just be her imagination though. She grinned, excitement filling her heart as she disappeared back into the water, her tail quickly morphing into legs as the magic took hold, making her more human like in order to help better catch the human un-aware.

Adagio glanced over at a nearby slightly submerged cave. "Lets take her to our special cave just in case of prying eyes. However low that chance may be, we can't take any right now."

Sonata clapped her webbed hands together. "Right behind you sister from another mister!"

Adagio was sure she was going to go blind with how much eye rolling she had to do among these two. Still though, at least when it came to feeding, she could usually count on them.

Sunset swam back towards the rocks, currently debating on heading back. She had just swam out a good ways, the water was warm but there really wasn't much to look at. She has hoping to find something to pass her fancy, something to help keep her invested. Perhaps a small reef or a strange rock formation. Something...

Then there it was. A sound. It almost sounded like singing. It was faint but seemed to capture her attention like no other harmony. Sunsets eyes fell on a slightly submerged cave, the waves lapping against the upper lip of it. The music was coming from inside it. There, perhaps, was that something.

Like a moth to a flame she felt her body be compelled towards it. Her arms began to move before she even realized it. Her legs kicking forward. She sucked in some air and dove inside, soon watching the world dim around her. Thankfully, there seemed to be light filtering into the large anti chamber of the cave from just in front of her. The small cave was just big enough for her to casually swim through. As she moved onwards, the song seemed to get stronger though somehow not really louder. The tempo was the same and yet, it seemed to drag her on with each push against the water.

She blinked and watched as the cave really opened up. There in the middle of the cave was a column of rock that shot up towards the surface of the water. As Sunset submerged, she was greeted with sunlight pouring in from small holes from above. The walls were mostly smooth and covered with streaks of lime stone. Her eyes glanced about before falling on the sound of the song. The top of the column was mostly flat and there on it, sat two woman. The water seemed to grow slightly warmer as she stared at them.

Their song seemed to echo slightly as their gaze turned towards her. The red headed woman was transfixed, looking over their wonderful bodies. The blue long haired woman had ample B cup breasts blocked only by the seaweed surrounding her and draping over her mid section. She was certainly naked though for the most part. Her eyes seemed to sparkle as her voice continued its sweet tune.

Next to her, on the opposite side of this small rock island, sat a curly, yet fluffy long dirty blond haired woman. She too had seaweed wrapped around her wonderful C cup breasts, almost if not around the same size as Sunset's. Her legs were open with the seaweed barely covering her slit. She seemed to beckon the woman in front of them, slowly reaching out her hand and gesturing for her to sit between them.

Sunset was at a loss for words. They seemed so beautiful and that song continued to wrap itself around her like a warm blanket, trying to get her to snuggle deeper into its depths.

This time she moved with her arms and legs, completely drawn to what she was seeing. Even as she swam closer, soon lifting herself onto the rock and sitting between these two woman, her mind seemed to be diving deeper into their enchanting song. She looked back and forth at the two, mesmerized.

The blond haired woman reached out, cupping her hand against Sunset's cheek, turning her head to look as they locked eyes. She smiled, her voice soon filling her ears with words that seemed different than the song. But still somehow sounded like it kept in tempo with it.

"We have been waiting for someone like you. My name is Adagio and this is Sonata. We wish to spend some time with you. Tell us, what is your name?"

"Sunset Shimmer." Her voice seemed almost alien to her. The red haired woman let out a small sigh, the hand against her cheek felt so smooth and warm.

Sunset's eyes dove down, looking at her wonderful form. Those luscious breasts seemed to bounce slightly as the sea weed slowly fell away from them, revealing their beauty and more of her soft skin. She glanced back up, losing herself in those eyes again.

"Sunset Shimmer?" Adagio repeated. "Well Sunset, would you like to spend some time with us? We would love to see what kinds of song your body can make with ours."

The red haired woman slowly nodded, lust slowly taking over as she continued to gaze at the woman still holding her.

She felt a pair of hands wrap around her mid section as she felt a smaller pair of melons smash against her back. "So glad you agree." Came a much more chipper voice from behind her. The song seemed to change tempo for a split second before returning to its enrapturing feeling. Sunset felt a warmth against her ear as she could just make out a low whisper. "Adagio is going to get you going but said I have first dibs. You are going to love what I have to give you."

With that, Adagio leaned forward, her lips coming to rest against Sunsets. The red haired woman closed her eyes, feeling the warm touch of her moist lips spread itself out. Her whole body seemed to grow warmer as she felt a sense of extacy soon enter her mind.

Adagio soon broke the kiss, saliva trailing from her lip as she slowly pulled back again. Her eyes seemed to shine again for a second as her hands fell to her bikini top. There was the feeling of someone, most likely Sonata, untying it as Adagio pulled it off and tossed it away from them. Sunset's melons bounced from the freedom. She wondered why she had ever worn it to begin with. Everything suddenly just seemed better without it.

She then slowly scooted up behind her as Sonata slipped in front of Sunset. The blue haired woman gently pushed against her shoulders, slowly getting the now dreamy eyed woman onto her back. As she leaned back, she could now feel her head now resting on Adagio's legs. The siren was sitting on her feet with her knees out, giving Sunset a wonderful place to rest her head as her eyes blinked up at her.

Adagio rubbed the sides of her face and neck. "Sonata has a special gift, rare among woman like us."

Sunset's eyes were drawn down as Sonata untied the bikini bottom, quickly pulling it away and revealing Sunset's moist flower for all to see. "Nice and clean down there... Yep, she is a keeper." Sonata said with a chuckle, her song was sounding more playful for a second before returning back to its usual constant lustful charm.

Sonata soon pulled away her seaweed, revealing something Sunset hadn't noticed before. Aside from having small but still decent sized assets, she had a particular long one trailing down the middle of her legs... And it was growing.

Sonata straddled herself over Sunset, lining up her cock with her wet entrance. The two shared a longing look before the blue haired woman grinned and slowly drove herself in.

There was a spike of pleasure that rang out in her mind before being replaced with more dull drone of wonderful song. Sonata let out a her hearty moan. "She is tight!" She sighed, pulling out before slowly pushing back in, even deeper than before. "So warm. So good... Oh yes!" She opened her mouth, seemingly tasting the air. Her eyes went wide. "Wow, you both feel and taste good!"

The blue haired futa pulled back a bit before driving back in again. She leaned over Sunset, their faces inches apart. "I love to watch the faces of those that I stick my cock into. Its more fun when we both enjoy the ride." She grinned and reared back before plunging back in again, causing Sunset to release a hearty moan.

"Aaahh... Sonata."

"Yep, that is the face I love to see." She reached out, grasping Sunset's breasts and massaging them. "And you have great tits... Where have you been all me life?" Her expression was full on joy but there was no denying the lust behind those words.

She began to pick up the pace, pulling back before slamming back in again. Each time she was pulling herself in, she would watch as Sunset would moan over and over again. Her thrusts were powerful, causing the red haired woman to shake with each forward motion. The siren leaned over her, feeling skin rub against one another. As their breasts mashed together, nipples grinding against one another, sending shivers down each others spines, both woman found themselves reach levels of pleasure they had not reached in a long time. "Oh yes... AH! That's it. I haAHve found... EHh... The perfect womAHn!"

Adagio watched the display, drinking in the love but finding herself slowly growing in need. "As much as I love a good show, sometimes I just have to get involved." She said with a slow sensual tone.

Slowly lifting Sunset's head up, she sat up, opening her legs. She turned around, still carefully holding this wonderful moaning woman's head, her back now to Sonata who let out an annoyed huff as she could no long see her cock sleeve's cute face.

Adagio positioned her soaking wet sex over Sunset's mouth, now slightly sitting over her face. She cradled that head, smashing it against her moistened slit. Sunset opened her mouth, her tongue soon finding its way inside. Adagio let out her own moan in between her hypnotizing song. It had been far too long since she had fed on someone while also receiving love in such a way.

Sonata leaned forward, love biting into Adagio's shoulder. If this siren was going to keep her from enjoying this, than at least that long curly haired woman was going to know how she felt about it. This woman she was currently plunging her long and hard dick into over and over again felt the best it had ever had. She wanted... No needed to really see that face. Really enjoy her touch. She was going to be far from done here soon.

She carefully whispered into Adagio's ear, hoping her leader would go along with her desires. Thankfully, over the throws of moaning and delight, the siren being eaten out by some good tongue work agreed, nodding her head. Sonata felt joy enter her heart like never before. She was so close but now she had to hold out.

Adagio meanwhile was knocking her head back. Her breasts shook as she found her body slowly trusting against that wonderful tongue, wishing it could go just a bit deeper. Even still, she gripped that fiery hair, messing it up a bit as she continued to ride the wave of pleasure. That tongue was lapping against her walls, filling her with a sense of love that she hadn't felt in so long. Now she was starting to understand how Sonata was feeling this. This woman was something else.

Even as Sunset shook, her walls tightening around Sonata's cock as she pulled out, wanting nothing more than to fill this woman with her wonderful cream, she had to wait it out just a bit longer. As juices began to spill out onto the rock, Adagio slowly crawled off, sighing in content as liquid spilled down her own legs. She was always silent about her orgasms' but Sonata could see that small look of content and knew that she was loving this just as much as the blue haired siren was.

Adagio moved behind Sunset, slowly pushing her up into a sitting position. Her mouth came close to Sunsets ear as she carefully whispered. "Sonata has something special in mind. Let her take you into the water and don't bother holding your breath, we will take care of that for you."

Confused but also still lost in the sea of lust, Sunset nodded. She slowly scooted forward, seeing Sonata slip into the water. The woman was singing with a slightly higher tempo, clearly giddy with excitement. As the red haired woman slipped off the rock and into the water, Sonata's hands reached around her waist, pulling her down. Sunset instinctively held her breath and closed her eyes, but a kiss from Sonata soon caused her to forget that. She exhaled from her nose, feeling the bubbles run past her.

She could feel something happen, her lungs did not ache and her breathing seemed somehow normal. Sunset opened her eyes; she was floating underwater. Sonata held her there, arms wrapped around her back as the Siren continued to kiss deeply. Her lips were soft and her body felt smooth. Both of their breasts smashed against each other. Just behind her, Sunset could feel Adagio swim up behind her, grasping her shoulders as she continued her song. Despite being under water, the song seemed to carry even better than before.

Adagio slowly whispered into her ear. "With this magic, we can keep you down here as long as we want. So kick back and relax because Sonata has something she really wants to give you." Her song slowly changed, its tune seemingly working its way over her body.

Sunset felt herself being wrapped in this warmth, a magical warmth that seemed to cover her completely. Sonata reared back and plundered her cock back deep into Sunset's core, who could only moan at the feeling. The blue haired siren pulled back, her voice echoing slightly in the water. "Now let me see your face, show me everything you have."

Sunset wasn't sure what she meant but as Sonata wrapped her legs around her, there bodies intertwining, she could feel the excitement within her grow. She could feel the mounting pleasure of another orgasm on the way. She could feel Adagio run her hands over her breasts, her song being fed directly into her ear as Sonata moaned like a creature in heat. Her eyes watched Sunset as she breathed in and out, moaning and gasping with each powerful thrust. Everything was overwhelming her senses and she was loving every second of it.

Sonata grinned. "I really wish AH humans and sirens could mate. Then we.... SO GOOD! Really could spend forever like this. But... OH! Dreams are just that, dreams. Still though... Ah! You truly are something. SO TIGHT! I want to see how you look... THAT's It! When I fill you with my siren seed. ALMOST I have a feeling its gonna be great!"

Sunset couldn't make heads or tails of what was happening any more. Her body was overflowing with pleasure. From Adagio's touch to Sonata's powerful thrusting dick, she could feel something building. Something wonderful about to happen. She let out a loud hard moan as she felt Sonata grip her tightly.

"CUMMING!"

A wave of white warm liquid suddenly rushed out, filling her with incredibly lovely seed. Sunset came harder than she ever had in her life, her cries escaping out and almost overwhelming the song. Sonata cried out too, now over joyed to have finally seen what Sunset's orgasm face looks like. She was more than full, she felt fulfilled. Eating love was one thing, this was another level entirely.

As Sonata hugged Sunset tightly, a part of her was now sad. She wanted to stay like this, floating forever with this wonderful woman. But she could also feel Adagio giving her a warning. They needed to move along. They could not risk draining her any more. Not that they could even if they wanted to. Sonata could tell by Adagio's content expression that she was full too.

Sunset felt her mind go fuzzy as a new song broke out from Adagio, it made her eye lids feel heavy and her mind go blank. The song carried itself into a sense of sleep as consciousness left Sunset completely.

***

Sunset Shimmer opened her eyes, the song was no longer there.

She was resting on the beach, waves covering her bare feet as she stared up at the setting sun. Her mind felt heavy but her body felt light. There was a brief wonder if everything that had just happened was simply a dream but a quick glance down at her naked body more than confirmed that did in fact happen. She could almost still feel that wonderful touch of those sirens, like they had only mere moments ago left her.

Sunset slowly sat up, brushing the sand off her body as she slowly got up and headed back towards her towel. As she neared her spot, she found Twilight, also naked and covered in dried fluids. She had on a dazed look as her eyes fell on the red haired woman.

"Siren?" Twilight asked in a slightly hoarse voice.

"Sirens, actually." Sunset answered with a smile.

Twilight gave a small nod as Sunset went to sit down beside her. As the two watched the sunset, Twilight reached over and grabbed a nearby water bottle. Taking a long sip from it, she passed it over to Sunset who also took a big gulp.

She wiped her mouth with her arm. "So... It seems the rumors were true."

Twilight slowly sat up and nodded. "Yep, Sirens exist around here. Probably came from Equestria somehow if I had to guess."

The red haired woman glanced over near the rocks, her eyes falling on a pair of eyes watching her. She could see the blue hair and locked eyes with her. She gave a slow wave just as the eyes disappeared beck into the water. "So... We may need to come back and learn more, right?"

"Oh absolutely. Really going to need to come back multiple times even. As many times as we can I would say." She grinned.

Sunset slowly started to grin as well. "Great, I may even have to do a little night watch some time, just to be sure."

The two glanced at each other before nodding. These sirens were going to be their main focus for quite some time.
