Cold, dark and wet. Those were the three sensations that immediately occurred to Rarity as she gradually opened her eyes. Her head was throbbing, and she knew straight away that something wasn't right. Where she was, or what was happening, she couldn't say. All she knew for certain was that she was in a bad situation. Trying to move, she found that she could not. By the feel of it, she was standing upright, with her arms stretched high above. Her wrists were tied to something, that much she could tell, as indeed were her ankles, though she still couldn't tell what they were tied to. She narrowed her eyes, straining to see anything around her. But with nothing but gloom, and only the barest trickle of light coming in from somewhere up above, this was an unsuccessful move on her part.
"Hello?"
Her voice echoed, and for a short time she heard nothing back. That is, until she started to hear something to her right. It was a groan of discomfort, and more than that, it was a very familiar one.
"Rainbow? Is that you?"
Here, her eyes were starting to get used to the tiny amount of light in here, and she saw that it was indeed Rainbow. Her athletic friend seemed to be in the same situation she was. Moreover, she could tell that she and her colleague were in some sort of cave, which naturally only served to deepened her concern over matters. In addition, only now did Rarity at last see what it was they were tied to. A stalagmite and stalactite, grown out from the ground and ceiling, were what their ankles and wrists were bound to respectively. Rainbow too seemed to struggle to see, but upon having heard Rarity's voice, she slowly turned, grimacing at taking all this in.
"R...Rarity? What's...what's going on?"
Rarity sighed.
"I wish I could tell you, darling."
"Ugh! My head hurts!"
The second voice caught both of them off-guard, and they simultaneously turned to see that it was none other than Pinkie, similarly bound. Like them, she was groggy from just walking up, and while she was normally the pinnacle of bubbliness and energy, this particular situation seemed to cause her little more than worry.
"Oh...dear."
"Yes, quite," Rarity agreed.
Now, these girls had been in their fair share of tight spots before, and as such they were more confident than most that they'd get out of this one. Having said that, however, they did wish they were dressed somewhat warmer, as they were all clad instead in their usual beach outfits, much to Rainbow's slight irritation.
"Remind me never to go snorkelling again!"
Rarity nodded.
"Indeed. I don't even remember what happened. We three went down, we looked around at some coral, and then...and then...nothing!"
The girls, in the silence that followed, tried to pull against the rope that was tying them to the natural cave formations they were stuck to, but to no avail. All they did was tire themselves out.
"Well...maybe our friends will get us out?" Pinkie suggested.
Rarity and Rainbow wanted to believe her, but with nothing but confusion playing out in their heads, they could dwell on little else right now. And that was when they heard the laughter. It took them all by surprise, and as it was still dark they couldn't make out who it was. Rainbow, peering through said darkness, started to scowl.
"Who is that?! Show yourself!"
Silence followed, but then, through the shadows and darkness of the cave, the girls could see three figures. In the cracks of the ceiling above, the streams of light began to move, no doubt through the movements of the sun in the sky, and this led to further illumination. As the light grew, the mysterious figures began to be more visible, and as this happened, the girls' eyes widened. They knew these foes well, though they had always hoped to never lay eyes on them again. Adagio Dazzle, Aria Blaze and Sonata Dusk. The Sirens of Equestria, here again. But there was something different about them. They were dressed not in the casual outfits with which they stalked the halls of Canterlot High, nor were they in the more elaborate dresses they had at the Battle of the Bands. Instead, the three were wearing only what appeared to be bathrobes, each individually coloured for their respective Siren. Purple for Adagio, green for Aria and Pink for Sonata. Rainbow, seeing her old enemies, was incensed.
"You?! What are you doing here?!"
Adagio, who was sitting down upon a large rock, merely looked amused at the threatening tone.
"What else? Revenge, my dear girl."
Rainbow struggled again against her bindings.
"When I get outta here, I'm gonna...!"
But the Sirens simply laughed together.
"Yeah, nice try, tough girl. You're not going anywhere," Aria declared.
"Not until we've had our fun anyway," Sonata added with a grin.
That particular statement sent a quick shiver down the girls' spines, but Pinkie, ever the optimist, looked to her friends with an albeit smaller-than-usual smile.
"Don't worry, girls. They've got no magic, remember?"
Adagio nodded, still smirking.
"You are right, of course. Our magic was taken in our last battle. But today..."
She closed her eyes, looking as though she was savouring some pleasant moment, before ultimately opening her eyes again.
"...we shall regain it."
The girls all looked horrified at that prospect. The Sirens were bad enough with their magic, and the thought of them getting it back was not pleasant in the slightest. Adagio, getting herself up from her stone, began to walk, and even in her current attire it could be seen that she was swaying her hips slightly as she did so.
"We thought long and hard on how to do this. And in the end, we knew there was only one way to do it."
"An old technique, and one we'd never thought of before," Aria continued.
"But it'll be fun, we promise that much," Sonata concluded.
Now, the Three Sirens were only a foot away from their prisoners, with Adagio standing in front of Rarity, Aria in front of Rainbow and Sonata in front of Pinkie. Reaching forward, Adagio carefully placed a single finger under Rarity's chin.
"It really is fortunate you decided to divide yourselves with that little deep-water swim of yours."
A chuckle escaped her.
"But of course, Sirens are very good underwater."
The Sirens laughed together, much to the girls' chagrin, but moments afterwards, Sonata looked to Pinkie, eyeing her white and pink swimsuit, before looking to Adagio.
"Hey, mine's not as easy to get to as yours, Adagio."
The Siren leader shrugged her shoulders.
"Well...rectify that then."
Sonata grinned wickedly, looking to Pinkie's midriff. She reached her hand forward, taking a firm hold of the fabric of he middle section of the girl's swimsuit, before unceremoniously yanking on it, tearing it from her body. The other girls, Pinkie especially, gasped at this, seeing that the party-lover's belly was now exposed from the effort. Sonata, looking rather pleased with what she'd done, discarded the torn fabric before placing her hands on her hips.
"Oh yeah, much better."
Naturally, Pinkie was completely taken aback by this, as were the others, but they had little choice but to put up with it for now. On the Sirens' side of things, they smiled darkly at their enemies, and then, almost in unison, they began to lift their hands to the ties of their bathrobes, undoing them. The girls, having no idea what was going on, watched as the Sirens began to slowly undress themselves, opening up their robes and allowing them to fall to the cold ground below. Now the girls could see that their Equestrian counters were, quite frankly, completely naked underneath, revealing all the curved and sensual splendour one would imagine when they thought of the bodies of Sirens. But as embarrassing as this was for the girls, something more than that caught their notice. Their eyes drifted downwards, and they saw something glittering within the now-exposed navels of the Sirens. Having stared long enough, they soon realised with horror what it was.
"Is...is that...?" Rarity began.
Licking her lips, Adagio nodded.
"Yes...that which you took from us."
It was, without question, the shattered remnants of their magical pendants. The fragmented red jewels had been cobbled together into a form vaguely reminiscent of their original shape, and had been embedded into the Sirens' navels. Even in this dim light, they sparkled menacingly. Adagio, glancing down briefly, smiled sweetly to hers.
"There's only a brief moment of magic within them...but that little taste is all we need."
Her eyes raised, bringing her gaze to the uncovered midriffs of the three girls before her, and she smiled hungrily.
"This spell is far older than we, and is nothing short of a last resort. Magic to magic. A conduit from which your power..."
Her hand gestured to the three of them, only to gently move beck to herself.
"...will flow to us."
Now having some vague idea of what was about to happen, the girls all tried once more to break free of their bonds, and again it did them no good. The Sirens, for their part, were greatly amused by their prisoners' attempts, and took slow steps forward, savouring what was to come. They lifted their arms, bringing them around the torso's of their soon-to-be victims. The girls looked increasingly fearful, much to the Siren's delight, and Adagio especially grinned, leaning in just close enough to whisper in Rarity's ear.
"Well...time for our fun."
And with that, they moved forward, bringing their bellies into contact with those of the bound girls. The latter three tried to move away, Rainbow doubly so, but given the way they had been tied up, there was, quite literally, very little wiggle room for them here. Meanwhile, lower down, the reassembled Siren jewels were poking into the navels of the three girls, and this contact sparked them off, causing them to glow brightly. Instantly, the Rainbooms grimaced, feeling the violating power of the Siren magic. It felt almost identical to the power that their friend Twilight had inadvertently used during their first meeting, when she took their magic also. It felt draining, exhausting, like losing something that was an integral part of them.
On the Siren side of things though, there was clearly a far more positive reception to this. Their faces lit up, looking utterly euphoric, as though they had wave after wave of pleasure passing through them. And each of them enjoyed this little triumph in their own way. Sonata lowered her hands along Pinkie's back, finding just the right spot and then pulling tighter, making sure she was pressed up against her belly as hard as she could be. Aria smirked, looking at Rainbow' struggling face, elated at the thought of breaking the "tough girl". As for Adagio, her grip over Rarity was so tight that she had no issue whatsoever in lifting her legs, making sure to sultrily stroke the back of Rarity's own legs with her feet, and using them to wrap around the fashionista's waist. As her ankles crossed on the other side, she used all four limps to further secure her hold of her.
Things were coming to a head now. The three girls could feel their precious magic weakening, growing lesser with every passing moment. It flowed from them, forcibly pulled from every inch of their bodies, all collecting into their midriffs, which of course then poured out of them and into the gems of their enemies. The magic subsequently passed into the Sirens' bodies, and with each second of it doing so, their ecstatic feeling grew, as though sensual in its nature. Aria and Sonata breathed more heavily, panting furiously with the feeling. And Adagio looked right into Rarity's eyes, seeing her become increasingly tired, and whispered yet again.
"Thank you...for this wonderful gift."
The gems glowed their absolute brightest, and there was an almost searing sensation for the Rainbooms, culminating in a joint scream between them. Then, after all that, the moment at last faded. Things calmed, and the Sirens slowly-but-surely released their grip on their enemies. The three captive girls began to breathe incredibly heavily, as though having gone through the most exhausting moment of their lives. They felt weak, and had they not been tied as thy were, they'd have likely collapsed to the ground. But Rarity, using what little strength she had, lifted her head, and saw the Sirens step away. The latter three looked to one another triumphantly, looking as though they had just experienced the most blissful moment in the world, with Adagio closing her eyes and giving a quick stretch. They seemed different, as if almost aglow, and when the Siren leader finally glanced back to her now-de-powered foes, she only had one thing to say.
"Three down...four to go."

You how, sometimes, you have this one image or moment stuck in your head that you think you might have seen as a kid? Something you're never quite sure if you watched in a movie or on TV, or possibly just imagined? Well, this story is pretty much based on one of those.
