"You're a great singer, you know that?" Pinkie said wistfully.

Princess Skystar's melody was interrupted by an equally musical bout of giggling. "Oh, not as good as you, silly."

"No," Pinkie whined. Her own eyes drifted shut, and she let her head drop to her marefriend's chest. "You're so beautiful. And your voice is so beautiful. And I can't believe I'm with somepony as beautiful as you."

"Back attcha, then," Sky teased, more giggles dripping from the ends of her words.

She reached up to scratch affectionately at Pinkie's jaw with her talons. Pinkie leaned into the gentle motion, beaming all the while. She knew exactly how lucky she was to be dating a creature with claws instead of hooves.

The hippogriffs, after all, tended to keep to themselves. It wasn't really anything serious; just a reflection and consequence of their time isolated from the rest of the creatures of the world. Few ponies would ever be so lucky as to enjoy the benefits of the extra appendages.

The thought of certain benefits made Pinkie's cheeks bloom pinker still, and she tucked her snout downwards, trailing it through the fluff of her marefriend's chest and planting the occasional kiss. Some fur, some feather… all of it softer and silkier than any pony Pinkie had been so close to.

Sky laughed louder now. She ended her song prematurely and wrapped her forelegs around the pony on her chest.

Pinkie's kisses traveled higher, and Sky traced the length of Pinkie's spine delicately with a single talon. The feeling made Pinkie shudder gleefully.

The girls laughed together, lost in each other. Pinkie's kisses traveled higher and higher, along Sky's neck, her jaw, and finally coming to…

The beak.

Pinkie hesitated.

Sky did, too, but only for a moment.

The hippogriff eventually let out a distracted sigh and dropped her forelegs down to her sides.

This was their one incompatibility.

"I'm sorry, I--"

"No, no!" Pinkie insisted. "I-it's alright! I just… I'm still not really sure how to…"

Sky reached up to cradle her marefriend's cheek. Pinkie leaned lovingly into her.

"Sometimes I wish you could… y'know. A little more often," Pinkie admitted softly.

"Agh, I know." Skystar covered her eyes with her claws, slowly drawing them downwards and pulling her lower eyelids into an expression of exasperation. "It's just that-- well, it's hard for me to get around when I have a tail instead of… legs."

"I know…" Pinkie rolled off of her marefriend and flopped onto the bed beside her. "But I'd really like to kiss you more often."

"You kiss me plenty!"

"On the lips, Sky!" Pinkie threw her hooves up in the air. "I wish I could kiss you on the lips way more often!"

Skystar rolled onto her side to face her marefriend more directly. "I can't keep using the pearl just to have you over. That's kind of irresponsible."

"I know…" Pinkie folded her forelegs over her chest. "But it's so fun! Especially for makin' whoopie!"

Sky snorted in laughter and gave her marefriend a playful shove. "Quit it, Pinkie!"

Pinkie razzed. "No way!"

The girls tussled with one another a little longer, but quickly came apart once more.

"It's okay," Pinkie said, her tone suggesting that this wasn't the least bit okay, but she would be willing to put up with it. "I get it. I wouldn't want to make you uncomfortable."

Skystar rolled onto her stomach. "We'll just have to get more creative, right?"

She chuckled to herself, using one wing to guide a single feather all the way up from Pinkie's stomach to her chin.

Pinkie seemed distant, though. "Um… what do you mean?"

Sky withdrew her wing. "Oh. I just meant…" the embarrassment overwhelmed her again. "Well, I dunno. We're smart, right? We can come up with a solution."

"Yeah…" Pinkie agreed softly. She appeared to be lost in thought, then suddenly screwed up her face in confusion. "Wait, nk! You were going to say something specific!"

"N-no I wasn't!" Skystar spluttered.

Pinkie drew in a comically deep gasp. "You were, too!" She rolled onto her stomach and settled her head in her hooves, much like a filly listening to gossip at a slumber party. "Spill, Sky!"

Skystar blushed even more fiercely and turned her head away from Pinkie. "No, no… i-it's silly…"

"So am I, but you still love me!" Pinkie beamed cheesily. "Right?"

Skystar giggled softly. "Yeah…"

"Right?" Pinkie hummed, nuzzling her marefriend's cheek.

"Of course I love you," Skystar relented.

"Great!" Pinkie exclaimed with her usual camp-counselor brightness. "Then tell me all your dirty, little secrets! Especially the silly ones!"

Sky put her head down on the pillow and sighed lightly. "Okay. I did have one idea."

Pinkie scooted closer to her marefriend, eyes wide and unblinking. "Mm-hm…"

"Well," Sky began in a huff, "the hippogriffs have a story about a kind of monster that lives in the sea."

"Ooh!" Pinkie clapped her hooves together. "Spooky, sexy fantasy!"

"Pinkie!" Sky scolded.

Pinkie giggled and pressed her hooves over her mouth. "Sorry, sorry."

Sky huffed again, tossing her mane in a manner which was not the least bit casual. "The monsters are called sirens," she explained. "They look a lot like us, but they have these magical singing voices that lure in unsuspecting ponies. Somewhere in there they… I dunno, I guess they have sex. I was never really clear on that part…"

Pinkie said nothing, as promised, just widened her eyes by another impossible degree.

"Well, anyway," Sky continued, "I was thinking we could find a nice, secluded beach and… I could play the siren."

Pinkie's eyes seemed to begin glittering on command, but she dutifully kept her mouth zipped shut.

"You can talk now, Pinkie," Sky said with a chuckle.

"Ohmigosh, that is such a great idea!" Pinkie exclaimed. She reached out and grabbed onto her marefriend with one hoof. "That way you can stay in the water, and I can stay pony! Perfect!"

"You think so?" Sky asked softly.

"Yes! It'll be the perfect day out with my marefriend. Or, ooh!" Pinkie pulled her partner close. "My… mer-friend. Eh?"

Sky clucked her tongue.

She loved it, though.

Pinkie Pie felt very exposed.

Not that she wasn't always this way-- in fact, Pinkie was never one for clothes when she could avoid it. A gala dress here, a themed costume there… but, without occasion, she preferred to go natural. One less thing to think about in the morning, right?

This was different, though. A very, very different sort of nude.

It was much like the difference between taking a shower and wearing one of those papery hospital gowns; in the shower, it felt perfectly normal. In the gown, however…

Pinkie peeked over the top of the boulder once more, surveying the beach for any sign of life-- pony or otherwise. All she caught a glimpse of was a crab scuttling through the washed-up kelp.

She breathed a sigh of relief, sinking back down into her sandy divot and staring out at the ocean.

It was a cold day. And windy. And a little rainy. They had picked this day on purpose, because, frankly, nopony likes to take a trip to the beach on a day that's windy, cold, and rainy. That was all well and good, but Pinkie's skin was beginning to feel kind of clammy and uncomfortable. The sand was starting to needle into her flesh, perhaps working deeper still into some of her more private areas.

Pinkie reflexively curled her tail over her exposed privates, then slowly laid it back down between her outstretched hind legs.

She was starting to get worried that Sky was having trouble in the turbulent waters. Sure, she knew her marefriend very well. One thing she knew with great certainty was that Sky was widely considered a strong swimmer… not that Pinkie would really know the difference. The more experienced hippocampus often allowed her marefriend to win in their races through the coral reefs.

The thought made Pinkie smile, a great momentary relief from the boredom which crept over her.

Yes, although Pinkie hated to admit it, her nervous excitement at the prospect of… well, of whatever it was exactly her marefriend had planned, was beginning to dwindle. All she could think about was the sand, the storm brewing, the possibility that somepony on the coast guard might stumble upon them and--

There.

Pinkie shifted herself into a more upright position, squinting into the distance. She held one hoof to her brow and strained into the ocean wind.

"Sky?" she murmured to herself.

Who else could it be? But the dark shape, watching her from a distant rocky outcropping, gave Pinkie a chill.

The wind whipped a little harsher, and Pinkie Pie braced against it. Just behind the sound of the wind, however, she heard it: singing.

Well, if you could call it singing. It was more like the haunting cry of a lone whale (though admittedly in a much higher register). Not exactly tuneless, but not really carrying a melody, either.

The shape dove into the waves.

Pinkie craned her neck, trying to catch another glimpse of the creature, but she could hardly see through her own messy mane as the wind battered it about her face.

Desperately, Pinkie pulled her mane away from her cheeks, watching the crests of the waves break against the rock where the creature had once perched. Nothing else seemed to happen.

The tide surged a bit, and the salty-smelling water lapped at Pinkie's rear hooves.

The pony nickered to herself in disappointment and slid all the way down onto her back in the sand. The water hovered around her hocks, but managed to tickle much higher as waves broke on the shore.

Pinkie hated to admit it, but this wasn't turning out at all like she'd hoped. She didn't even think she was the slightest bit aroused anymore, just… annoyed. And uncomfortable. And confused.

She just wanted to be with her marefriend again. Even if that meant an unkissable beak.

But the sound came again-- more almost-notes-but-not-quite, echoing… no, vibrating through Pinkie's back legs, as if amplified by the water. Carried through it. Better than any sound should have been able to carry.

Pinkie sat up, pressing her hooves into the sand for support as she scanned the water once more.

It took her a moment to spot them, but they were there: two shimmering eyes, just beneath the water's surface. Looking right at her.

Pinkie gasped softly and put a hoof to her lips. Though she, of course, recognized her marefriend immediately, there was a sparkle of something utterly unfamiliar in her eyes.

Sky rose just a bit higher in the water, which parted over her head like sheer silk. She bobbed with the waves as easily as a buoy.

Pinkie very slowly withdrew one of her rear hooves and tried to push herself into a more upright position.

Sky did not move. Did not blink.

It was starting to dawn on Pinkie that she was going to have to find a way to play along in this little fantasy, a role which she had not truly considered until this moment. Did Sky expect her to say something? It was so hard to tell, her eyes were blank and glassy, absent of all motivation.

Except maybe for hunger.

It really was like looking at a… well, at an alien, for lack of a better word. The Sky that Pinkie knew had quite a bit of trouble staying quiet.

"Um…" Pinkie paused, cleared her throat, and pushed herself up a little higher. Her heart was thrumming in her chest. "Hello? Wh-who's there?"

Sky closed her eyes and dipped under the surface, but only just. Pinkie watched in awe as her marefriend opened her mouth and let loose another powerful, meandering, alien note. She really had to lean into it, Pinkie noticed; she extended her neck forward in such a way that must have opened her entire throat up to the sound. And the ocean water.

Her bioluminescent light cast a strange, ghostly tone over her face.

Pinkie curled into herself all the more. As much as she didn't want to admit it, she actually felt sort of… scared.

A tingly scared.

A good scared?

Skystar ended her brief song, and powered herself forward with just a few quick strokes of her massive tail.

Pinkie scrabbled against the sand until her back was against the large stone she'd selected as cover. It was somehow colder and clammier than her skin.

Skystar's body emerged from the water.

There would have been no trouble believing that this creature was a siren. The princess had shed her usual jewelry in favor of an elaborate draping of thick, salty belts of kelp. And the way she moved-- drawn forward by hooves dug into the sand, her tail slithering over the shore… it was unlike anything Pinkie had seen before.

Pinkie drew in a strained gasp and pressed her hooves over her mouth. Even with the freezing, damp wind blowing over her small frame, the pony couldn't seem to move as her beloved approached.

It was only when Skystar straddled Pinkie--when they were absolutely nose to nose--that even a shadow of familiarity crossed the hippogriff's face.

The girls stared at one another.

Pinkie could feel her own heart thudding against her ribcage. She felt that, if she drew her hooves away from her mouth, she may just bust out laughing.

And so she sat, frozen perfectly still, each shaking breath bringing her closer to losing it.

She is the element of laughter, after all.

Skystar knew this, of course, and wasted no time in getting to her point.

"I know what you want," the princess whispered. Her breath was warm and wet on Pinkies snout. Her very voice seemed to stick there upon her face.

A different voice.

A voice that made Pinkie bristle from something other than the chill.

As if on cue, the sea wind whipped up and swirled over and through the pair of ponies on the shore. It made Pinkie shiver. Still, she did not move or speak. She may not have even breathed.

Sky lifted one hoof and just barely grazed Pinkie's ribcage with a strangely firm flipper.

This earned a long, shuddering breath.

Sky continued to trail downwards, her fin tracing along the delicate lines of her marefriend's body, until she reached the rising slope of her hind leg. In one swift movement, she forced the leg open and down.

Pinkie made a strangled sound--something between a gasp and a moan--and plunged one front hoof into the sand.

The wind was cold and wet as it danced over Pinkie's exposed marehood. She bit down on her lip to keep from making sound, yet a few desperate whimpers still escaped.

A strange new look crossed Skystar's face. It wasn't quite lust, nor was it any sort of glee over the dazzled sparkle in Pinkie's eyes.

It was hunger. Pure and ravenous.

Pinkie could not pull her eyes away from her marefriend. Even as the wind blew over her throbbing clitoris, even as she tried to slowly extricate herself from her marefriend's grip, even as Skystar's eyes darkened like storm clouds over the ocean, Pinkie could not look away.

Skystar made a sound deep in her throat. It was like whalesong, if whalesong could be aggressive. A muscular thrumming that sent a ripple through the muscles in her neck.

Pinkie shuddered.

With another silky fin, Skystar cupped the gentle slope of Pinkie's rump. Her touch was feather-light and chilling, and Pinkie rocked her head back, eyes drifting up to the sky before fluttering shut.

"Look at me," Skystar commanded.

Pinkie, surprised by the force of her marefriend's voice, looked.

"What color do you see in my eyes?"

It sparked some sort of memory in the very back of Pinkie's mind. An agreement! She was supposed to say something… she couldn't remember. Not for the life of her. Looking at Skystar like this had just fractured her mind, and any memory of the real world was separated from the electric feeling coursing through her veins right now.

"Pinkie?" Skystar whispered.

And, for that one moment, it was her again.

Pinkie remembered. "G-green…" she breathed.

"You're sure?" Skystar whispered again. Her tail flicked through the sand, leaving a trail like a serpent.

Pinkie nodded vehemently.

Familiarity vanished.

Skystar gave Pinkie's hind leg a sharp tug, pulled her off of the stone she had been using as a headrest and dragging her some distance through the sand.

Pinkie yelped, then pressed her hooves to her mouth again.

The ocean surged, and chilly saltwater climbed up around Pinkie's stomach. As it drained away, it ran down between her legs, trickling tantalizingly over her marehood.

Skystar must have seen the lustful glint in her prey's eyes. She pulled Pinkie down further, further, as if she were planning to take her out to sea.

It occurred to Pinkie that this may actually have been part of Skystar's plan. Her chest tightened in anticipation, as if she were awaiting the first drop on a rollercoaster.

The water was up around her ribcage, now. The waves surged once more, and Pinkie had to close her eyes for fear of the spray. Though it didn't come close to covering her muzzle, the wave did rush over her ears. In that moment, the sharp edges of the world were ripped away, and everything became muffled and distant.

It was barely a moment, though. Skystar allowed the wave to pull her deeper into the water, though she kept her front hooves anchored to Pinkie's sides. Pinkie could feel them trace down both sides of her waist, over her hips, and finally land on her haunches. In that motion, she could feel the precise acceleration of the wave, and the tiny grains of sand stuck to Skystar's flippers were like pinpricks on Pinkie's skin.

It was the little things that grounded Pinkie so completely, that made it impossible to tear herself out of the fantasy.

But… gosh, it was so exciting.

The water rushed up once more. It threaded itself between Sky's hooves and Pinkie's skin, feeling not unlike a slippery tongue searching for its prize.

Pinkie looked up.

Skystar was staring back at her, the water lapping at her cheeks.

She said nothing. Pinkie didn't even hear a sound as her jaw opened and her tongue slid out.

Pinkie's first thought was I do not remember Sky's tongue being so long.

Her second thought, however, was drowned out by pleasure.

All the anticipation that had wound up in Pinkie's chest uncoiled itself as Skystar's monstrously transformed tongue swirled over her clitoris. It was gentle--an unexpected feeling in and of itself--but also so warm compared to the salty ocean water which was mingling with her saliva.

Pinkie's head dropped back into the sand, and she let out a long, shuddering moan. She could feel her muscles relaxing, her body relenting, her eyes fluttering closed.

Skystar continued, her pace unbearably slow but her movements perfectly precise. She seemed in sync with Pinkie's own body, following the rise and fall of her own rhythmic pulses.

But so slow.

Pinkie was starting to understand how sex played into this whole temptation myth. She would gladly allow her marefriend to drag her out to sea if it meant that this long, low wave of pleasure could keep on a little longer. She would gladly allow a creature who was decidedly not her marefriend to do the same, she figured.

Of course, the longer she mellowed in it, the more she felt the wave building.

And, gosh, something about the thought of her marefriend being so… so raw and wild, she supposed, was irresistible.

The agreement at home was so simple: all about pleasure, all about warmth, all about love.

But the rules had been broken.

Anything could happen.

The wave built further still.

The water surged again, splashing over Skystar's head and rushing up to Pinkie's chin. She strained to keep her head above the water, but drew in a sharp breath just in case it managed to overtake her.

Skystar, not wanting her prey to rest so easily, gave Pinkie another small tug.

That was all it took for the water to gather around Pinkie's snout. Though it was by no means submerged, the water splashed this way and that, and Pinkie had to struggle a bit to keep from choking on seawater.

Even as she did, Skystar's meticulous exploration of her marefriend's clit did not slow or stop.

The desperate little breaths that Pinkie could manage to sneak in only caused her to release some of the more primal sounds she'd been holding back. The wave receded, but Pinkie found she simply couldn't hold back anymore.

"Sky," she moaned, barely more than the gentle sounds of the wind.

By some miracle, Skystar heard the plea, and she lifted her head. The water parted, and her tongue lingered, though it didn't move.

Pinkie made a small sound, something between pleasure and frustration. "Sky, please," she begged, not bothering to specify.

Sky held Pinkie's gaze a moment longer. She was trying very hard to disguise the distinct twinkle which flashed through them, but she wasn't quite deep enough in character to suppress it entirely.

Pinkie opened her mouth to continue her plea, but Sky had other plans.

She lowered her head once more, this time slipping her tongue inside of Pinkie. Pinkie drew in a breath which started as a gasp, but ended abruptly before turning into a moan.

The Incredible length of this newly-transformed muscle coiled itself inside Pinkie, and she could feel with acute detail how it swirled over her inner walls. All the while, the base of Sky's tongue pulsed in rhythm with the writhings of the tip, and each motion sent a wave of pressure over her clit.

Of course, just as Pinkie dropped her head into the sand once more, intending to enjoy this turn of events, Skystar clamped down.

The feeling was hard to explain. It wasn't painful, not like a bite-- it was more like being grabbed very forcefully from the inside. And, Celestia, did Sky have a fantastic grip.

Pinkie could hardly even react as her marefriend scrambled backwards, looking more and more like a wild animal, and pulled Pinkie much further into the water. She may have let out a cry of surprise, but, if she had, it was entirely involuntary.

From here, the water was tickling Pinkie's cheeks. A wave--any wave--would submerge her completely.

Pinkie's breaths quickened and deepened as she tried to ensure she had a good lungful of air. The threat of vanishing underwater at any moment made her chest-- well, not tighten, exactly. It wasn't fear. It was a rush. The same rush you feel as when you sail through the air before diving into unfamiliar waters.

Skystar watched carefully, not making any move to continue until she heard--

"Green!" Pinkie spluttered, drawing in another quick gasp of air. "Please! Green!"

That glint flashed through Sky's eyes once more, and she withdrew her tongue from Pinkie's vagina with a flick.

The water rushed out a bit, and a momentary silence overtook the pair. Skystar was poised over Pinkie, her tongue lolling greedily out of her mouth. Pinkie was still panting heavily.

A wave was coming.

That's what the rush out meant, wasn't it?

It meant a wave was coming.

A monstrous wave that would spray over Skystar's head and crash down on top of Pinkie and--

Pinkie didn't have time to think. She took an enormous breath, as deep as she could stand.

Skystar took this opportunity to guide her tongue back through the folds of Pinkie's marehood, squirming rhythmically over her clit.

The wave came.

It wasn't quite as impressive as perhaps Pinkie had imagined, but it certainly did have a force which nearly made her forget herself. It slammed down onto her chest, threatening to knock the wind right out of her. But, as the initial impact wore off, Pinkie found herself floating up off the sand.

It was hardly more than an inch, but the weightlessness the water gave her somehow intensified everything else.

Skystar's tongue danced over Pinkie's clit expertly, and Pinkie tried her damnedest to focus on her breath.

She was good at holding her breath. Not that she'd practiced or anything, but-- well, it hadn't been something worth practicing before. She hadn't ever seen the need to exercise her lung capacity or breath control.

But now…

Pinkie kicked one hind leg, like a tiny buck of rebuttal, but did not push off the sand to breach the surface of the wave.

She held her breath.

It was easier said than done. Pinkie fought the urge to gasp in pleasure as her marefriend's tongue swirled and swooped through Pinkie's marehood. It had enough length to at once tickle her opening and massage her clit, and Sky didn't dare waste such an ability.

Pinkie held her breath, but it was so much more active than she imagined. Being deprived of air is one thing--gagged or choked or something--but trying not to breathe when you could is another entirely. Pinkie's chest made heaving, wave-like motions of its own as she clenched her muscles and tried not to give into temptation. She even made a tiny strangled noise, not unlike the gag of a throat stuffed full of--

It wasn't like a wave could last all that long. But, by Celestia, did this one feel like an eternity.

The pressure was building, steadily and earnestly, in her nethers. Between the warmth of Skystar's tongue slipped the occasional icy shock of ocean water, a feeling which also begged Pinkie to gasp aloud.

Just as Pinkie was starting to think she might not make it, she could feel the water begin to rush the opposite direction. She let out a small sound of relief, which rolled up to the surface in a self-contained bubble, as her mane was pulled down around her cheeks.

Her snout was the first thing to greet the air, and Pinkie cheated by stretching up to draw in a breath from her mouth.

A loud breath.

And a louder cry of pleasure-- almost the temptress's name, but too far past language to be sure.

Skystar was undeterred. Even as Pinkie gasped and squealed and panted, lying spent in the sand, Skystar continued her slow and methodical exploration of Pinkie's marehood.

Pinkie was starting to realize the appeal of such games.

She already felt as though she'd orgasmed. That full-body relaxation that comes from the release of tension--she felt it as her breathing slowed, that empty-headed bliss that comes along with a lungful of sea air--was that what oxygen deprivation did to you? She was hardly deprived for long at all.

And yet, the pressure built.

Maybe it wasn't like one orgasm after another. Maybe it was like one long climax, a burning, rushing feeling that Skystar could keep alive as long as her tongue continued to draw hypnotic shapes over Pinkie's winking clit.

That wasn't even to mention the shocking eroticism of her marefriend's feral appearance.

Pinkie struggled to get her breathing back under control. As it stood, she was something of a panting, blubbering mess-- little murmurings of pleasure sprinkled in amongst the gasping.

"Sky…" Pinkie whispered, more of an impulse than anything else.

Skystar, however, seemed to take this as some sort of signal.

She withdrew her tongue and lifted her head. Not much, just enough to easily look her marefriend in the eye.

Pinkie made a desperate little sound as her privates met the chill of the air.

"Do you want to come with me?" Skystar asked. "I can't finish if you don't agree."

Of course.

Either Skystar was very good at reading between the lines, or she had cleverly kept some details of the myth from Pinkie. Sirens didn't use the temptation of sex to lure their victims to certain doom-- they threatened to take it away.

And so the choice became clear: stay on the beach, unfulfilled, or risk the open water for the certainty of pleasure.

Well. Perhaps not so certain in the original myth.

Very certainly in this one.

And yet, even as Pinkie wanted nothing more than to grab her marefriend by the temples and pull her into her nethers, she was paralyzed. Here, by the shore, things felt very safe. It was easy to sneak a breath or scramble away if things suddenly went awry.

In the open ocean, though…

Skystar, sensing Pinkie's apprehension, began to haul herself out of the water. Her powerful swimmer's legs straddled Pinkie, and she managed to crawl her way up onto the sand until she was eye to eye with the earth pony.

Pinkie curled her hooves up to her chest and gazed longingly at Skystar.

"Pinkie," the siren said, shadows of the princess hidden inside.

Pinkie pricked her ears up and made a small sound.

"You know I'll keep you safe, don't you?" Skystar whispered.

Those simple words, murmured under the sound of crashing waves and harsh winds, made Pinkie's chest swell with warmth and love. She stared up at her marefriend, at the salty spray and the sand in her fur, at the kelp which hung about her face, and at the softness of her lips.

Pinkie reached up and hooked her front legs around Skystar's neck. Thoughts of the scene momentarily forgotten, she planted a long, gentle kiss on the now-kissable lips of her marefriend.

Skystar let a small giggle escape her, but the bubbly sound served only to remind her of her role in the game.

The hippogriff scooped one fin under Pinkie's shoulder and hoisted her off the ground another inch or so.

"Is that a yes?" she hissed into her prey's ear.

Pinkie squealed in delight. "Yes! Yes!" she squeaked in reply, kicking her back hooves against the sound with a feverish energy.

Skystar let a smirk play over her lips before snarling "hold on" and whipping around to face the ocean.

Before Pinkie had time to get her bearings, Skystar dove into the ocean. The ponies flew through the water, chest-to-chest, and Pinkie started to realize that she'd hardly taken a breath.

Skystar was paying attention, though. In one smooth motion, she rolled upside down and allowed Pinkie to breach the surface of the water for a gulp of air. Here they stayed, Pinkie gleefully taking in the fresh air as it rushed past her and Skystar gliding through the open waters with the grace of a dolphin.

In fact, as Skystar's tail pumped rhythmically up and down, Pinkie couldn't help but appreciate the steady pressure on her nethers.

Keeping her eyes locked with Skystar's, Pinkie allowed herself to fall back towards her hips and opened her hind legs a little more.

The feeling of the smooth scales writhing against Pinkie's exposed marehood was more than enough to keep her arousal alive as they moved out to sea. Pinkie even fell into a rhythm against the tail, grinding ever so slowly up and down in time with each powerful pump. The temptation to cheat--to get herself off right here, right now--was present, but Skystar expertly slowed her movements to a crawl as she felt Pinkie's enthusiasm grow.

Slow became slower.

Pinkie whined softly.

Slower became stopped.

Pinkie slipped as her marefriend slowly sank lower in the water, no longer a sufficient buoy for the earth pony to balance upon.

"Stay," Skystar hissed as her muzzle disappeared beneath the surface.

The water was dark.

Too dark to see through. Too dark to know what was being planned.

Pinkie's cheek-to-cheek grin slowly faded as the vastness of the open ocean reentered her tunnel vision.

The ocean water lapped at her neck.

Pinkie treaded water with her forehooves, bobbing slightly with the swell of the growing waves.

She swiveled in the water, looking back towards the shore.

There was no shore to be seen.

Pinkie swallowed. "Uh… Sky?" she forced a nervous chuckle as she looked down into the murky water, searching for any sign of motion. "Sky? Y'there? Y-you've been down there a--"

And the pressure returned.

Pinkie's words died in her throat as she felt herself being lifted through the water, gently turned until her round, pink stomach breached the surface and her marefriend reappeared.

Her face was buried between Pinkie's legs. Her tongue once again lashing at Pinkie's clit and burrowing into her warm pussy. While her focus did not dwindle, her eyes were riveted on her marefriend, glinting menacingly.

Pinkie struggled to keep her head above water. Every twitch and moan, every minute freezing of her limbs as the beast between her legs found the right angle, caused water to splash over her face. If her focus drifted from treading water for even a second, she would find herself sinking through the dark water, once again fighting for oxygen.

But the deeper Skystar drove into Pinkie, the longer she lingered in those little circles over Pinkie's clit, the harder Pinkie shook with pleasure… the more lost she became in the fantasy.

It was hardly even a fantasy anymore.

A beautiful, alluring monster wanted her. Wanted her bad enough to drag her out to sea and eat her from the inside out.

Pinkie gasped as her head bobbed through the waves. Each breath of salty air was like a tiny orgasm, an explosion in her mouth and lungs. Skystar's fins wandered delicately along her spine and haunches, even as her tongue lashed harder and harder and--

Another wave.

Pinkie drew in an enormous breath as the water crashed over her head, at last sending her completely underwater.

Skystar did not stop.

Even as Pinkie struggled to find the way up, even as she grunted and gagged and held back her moans through her desperate need for a fresh breath of air, Skystar did not stop.

The siren did not stop.

Pinkie's frantic paddling slowed.

More and more of her attention was centered on the pressure that The Monster expertly built.

And Pinkie made a choice.

She surged upwards, filling her lungs with as much air as she could possibly manage. Full to bursting.

Then, she slowly sank beneath the surface of the water.

The Monster reacted accordingly. After a moment's pause to evaluate her prey (and after spotting the desperate look in her eyes), The Monster swam up to meet her mark face to face.

Pinkie reached out, grabbing at The Monster's face and chest, pulling her in closer and silently begging her to finish.

In return, The Monster trilled. The sound echoed through the water and sent a chill up and down Pinkie's spine. She could have sworn it sent a pulse through her body, clenching her clit and releasing another jolt of pleasure.

The Monster reached out.

As promised, the lovers' lips met. At long last, a kiss that felt real. Not stolen.

Pinkie pressed into The Monster as they sank deeper into the chilly depths. She made a tiny, desperate sound as she fought against the urge to breathe and her mouth filled with seawater.

But The Monster had an answer for that, too.

Pinkie felt an alien presence in her mouth.

Something thin and slick, yet muscular as it wound its way between her lips.

It took Pinkie a long moment to realize that The Monster was looking for a new place to slip her tongue.

Well. It wasn't like she could breathe, anyway.

Pinkie tipped her head back ever so slightly and closed her eyes, the clearest invitation she could think of. The Monster, of course, took it.

She was gentle with it. Her tongue wound over and around Pinkie's, performing a slow and methodical dance as it inched its way towards the back of her throat.

Pinkie had taken a few things into her throat before. Namely penises, but her marefriend's carefully-trimmed claws had found their way inside on a few occasions. This feeling, however, was not remotely similar--in fact, this was nothing like Pinkie had ever felt before. The tongue had agency, could reach down deep and continue to squirm, could fill her throat to bulging and still pulse and writhe within.

With air to spare, Pinkie pawed at The Monster that held her. She clung to her tightly as the pair floated, suspended in joint ecstacy in the open ocean.

Then The Monster's tail rose.

Pinkie locked her rear legs around The Monster's body and held as firm as she could. The Monster's tail undulated between her legs, rubbing her clit even as her tongue was otherwise occupied.

As Pinkie squeezed tighter and tighter, riding the waves of The Monster's body closer to orgasm, she thought how lucky it was that her marefriend had not one but two prehensile limbs.

She wouldn't last long now. The rising waves of pressure and heat in her nethers combined with the need for oxygen were moving as one, combining into a singular massive wall which threatened to crash atop her any moment now.

Pinkie grunted as the first chill came over her, a sound muted by the tongue in her throat at the water in her ears. As the wave of her orgasm crested, she tried to howl, and her throat clenched around The Monster's tongue. Sensing that they were nearing the end of the time beneath the waves, The Monster began to swim upwards.

The promise of a lungful of fresh air made Pinkie submit fully to the whims of her captor.

Her face broke the surface.

The tongue came flying out of her throat, a spray of saliva and sea water in its wake.

Pinkie breathed.

She came.

All in a singular moment, one which made her throw back her head and scream as loud as she possibly could. An utterly inequine sound which seemed to come from deep inside her, deeper even than Skystar's tongue had explored.

Skystar.

She was Skystar again. The darkness in her eyes was replaced by that delighted twinkle, and an enchanting giggle bubbled forth from her still-equine lips.

Pinkie beamed. She laid back in the water and allowed it to carry her as she tried to catch her breath.

And, for the first time, Pinkie realized how quiet it was out here. How utterly serene. How the sounds of the water were barely audible over her own panting, and how the air was in constant, predictable motion over her face.

She basked in it, allowing the stillness to wash over her in another, different sort of wave. The pleasure of stillness. The pleasure of after.

Skystar used one hoof to lift the seaweed off of her face. "I'd ask if you had a good time, but based on the look on your face I don't think I have to."

Pinkie let out a contented sigh. "You betcha," she agreed. "And don't think I won't get you back-- I will."

"You always do," Skystar said, another giggle escaping her. "So… you think we'll do something like this again?"

Pinkie perked up, momentarily losing her balance in the water. "Are you kidding?! Totally!" she exclaimed, kicking up a good splash in Skystar's face. "On one condition, though."

"Oh, yeah?" Skystar smirked. "And what's that?"

"Next time, I get to be the monster."
