Rarity may try to stop herself from visiting Adagio, but the Siren's song of bindings, whipping, and insulting always lulls her back eventually...

Rarity’s job often leaves her very stressed out, and there are only a few ways to truly relieve herself of that stress. Travelling to another city to visit a very specific club and its owner was hardly the easiest answer, and has made her friends very suspicious of her, but that Siren’s song that stung at her flesh was far too tempting...

Fleeing from Freedom

She knew she shouldn’t be there. She was a lady, after all, and ladies don’t go to... well, places like this.

The slow, sensual music all around the large open room, the dim lighting that flooded it all, tinted with reds and purples that made her felt comforted yet excited, and all the thick, plush seats strewn around with patrons of all shapes, sizes, and species sitting amongst them with an air of intoxicated lack of restraint. Even more were sitting on stools at the bar to the side, alcohol clearly flowing through them in all different ways, but was controlled by the cheery blue bartender who was a kind of creature all too familiar to her...

Oh, but she shouldn’t forget the metal poles that all the patrons’ attention were on, fixed as they were to large round stages of sorts keeping the bottom off the floor while the top must’ve reached the ceiling, with some of the sexiest creatures she’d ever seen, both male and female, dancing on those poles. Their bodies swayed and contorted in ways she barely believed was possible, all to show off their bodies, clearly carved and clad to be the most enticing things possible...

She was supposed to be heterosexual, and was very confident and comfortable with that in the past, but now that she’s seen what those women can do with their wings, tongues, tails, and everything in between, she was hardly all that sure any more.

“Hello there, my precious diamond~” A feminine voice then suddenly spoke into her ear, its volume quiet and whispery, but its tone filled with dominance and lust.

Well, scratch that previous thought--she knew she wasn’t straight at this point!

She didn’t have to look back to know Adagio Dazzle, the leader of the only three Sirens in the world, who also ran this club in each of its facets, and were all masters of manipulation (and possibly immortal?), was standing right behind her, leaning forward over the back of the otherwise empty booth she was sitting at and whispering into her ear. “I know you couldn’t stay away from here for long, dear Rarity...”

Rarity both loved and hated that sentiment, the former due to her borderline-addiction to the sensual Siren with her gorgeous golden scales, massive head of fluffy hair, and thick fish-like tail, and she felt the latter with the encroaching thoughts of her friends and family, who often voiced their worry about her going off the radar for multiple days in a row, and would no doubt want her away from the seductress sea creature if they ever knew what she got up to.

But at this point, she’d already gotten so far...

Leaning back from her former stiff pose into the plush seat, Rarity let her head hang backward to see the Siren’s piercing purple eyes gazing back at her with a thinly-veiled want. “H-hello again, Darling,” She said, trying to keep up her usual ladylike demeanor, but she knew she wasn’t fooling anyone.

Adagio smiled back at her nonetheless and pulled to the side just enough so Rarity could get a better view of her face in the lustful lighting of the club, the gleaming scales in place of fluffy fur, though such fluffiness was compensated for by all the poofiness hanging from the back of her head. Her ears were instead replaced by fins on the side of her head, thin membranes with some gold and amethyst piercings, and her neck had darker flaps on both sides that Rarity had since learned are gills.

But, the most striking thing about what she could see at that moment were the aforementioned eyes that tore through any mental resistance the Unicorn could put up, finding her deepest and darkest secrets with just a simple look, and the sharp teeth that filled her mouth below, which itself was raised in a devious, cruel, and dominating grin. The Siren was in complete control here, and Rarity knew it, and she couldn’t help but melt into it.

Suddenly though, a gasp was forced out of her mouth as she felt one of her breasts getting squeezed, and the smug, casual dominance from the woman before her made it immediately what was causing it. She could feel that smooth, scaled arm reach under her silky purple dress and go down along her side, then reach around to grab her rather small, yet pronounced breast.

Rarity could already tell how hard she was blushing, with the domineering stare pointed at her along with the casual groping of her tit, all of it happening in a (semi-) public space where any of the other patrons could see it… She felt embarrassed and rather ashamed of giving into the pleasure that ensued, and couldn’t bring herself to pull away from the other creature, but did lower her head to try and hide her face to protect her dignity.

“Oh, come now, my Diamond…” Adagio teased into Rarity’s wilted ear, “Don’t bother hiding what we all know to be true…”

Rarity could feel the gaze of the Siren crawling all over her back, but the way that statement was worded made her turn her eyes up to tentatively glance across the rest of the room. She once again was met with the luscious sights of nearly-nude creatures showing off their delicious bodies with active, yet sensual motions, but the bar drew her gaze, with the patrons still not paying her any mind, but the bartender was looking right back at her, a giddy, knowing smile on her face as she watched her sister toy with her patron.

Blushing harder at knowing she was being watched, Rarity turned her head right back down to avoid the gazes of the two Sirens, Adagio in particular chuckling into her ear. The Unicorn then felt Adagio tracing a finger down her side, both hands now being used to capture and prevent her from escaping…

“As much as I love teasing you out here,” The Siren begun, her voice slow and teasing, but still quite honest, “There are many other ways I prefer to examine my Diamond…”

Shuddering at the implications, Rarity already knew full well what they were soon to get up to, and mustered as much confidence as she could into her voice to retort, “I-I’d like nothing else.”

The large double doors from the main room closed behind them, and Rarity was greeted with the familiar sight of Adagio’s chambers--or rather, her Mistress’s chambers, as would be more proper here. The room was far more lit than the main one, making more visible the purple carpeting across the entire floor, as well as the massive four-poster bed in the center-back of the room. However, the walls were what drew the most attention, as laying upon the many hooks and shelves attached to the walls were a true myriad of sex toys, ranging from simple vibrators, strap-ons, and paddles, all the way to full-on whips, and gimp suits, and there was also a set of ropes hanging from the ceiling to the side of the bed Rarity wasn’t quite sure what was for.

Still, she felt her entire body heat up at the sight of it all, especially with all the faint scars that still were littered across her body from the previous times she’d been there. Her gaze quickly went back to Adagio, some of her golden scales covered by a thin purple nightgown that she wasted no time in taking off and tossing onto her bed.

What the Siren was left wearing made Rarity only more enraptured, as deep purple leather clung to her thick, strong legs in the form of high heel, knee-length boots, and her toned midsection was tightly gripped by a corset of the same colour, pushing up her relatively meager breasts to what could pass a couple cups up at a glance. Her arms though, were still bare, but that was only for a moment as Adagio quickly found her way to the (very specifically modeled) mannequin on the side of the room and pulled the arm-length leather gloves off it, then swiftly, yet carefully pulled them up onto her own arms, truly completing the look of Mistress Adagio.

“My Diamond shouldn’t need to cover her body,” Mistress spoke, her tone now clearly that of a command, one that Rarity couldn’t help but obey.

Quickly, she pulled her dress over her head while approaching the bed, then tossed the dress onto it before then stepping out of her heels, and setting those aside near the bed as well. And just like that, her dainty pearl-white form was now completely bare of covering, as she didn’t bother to wear any panties or a bra, and socks would make no sense on the heels she wore. However, there were some small things that marred it, mostly just the faint scars...

Mistress Adagio then turned around to look at Rarity, and immediately, the Unicorn felt even more exposed than before, with the deep, dark purple outfit shrouding the Siren in an air of absolute authority while accentuating the colour of her eyes, which themselves tore into Rarity, examining closely at every nook, cranny, and wound of the nude mare’s utterly exposed body. She seemed pleased, thankfully, as a light upturn of her otherwise unreadable smirk showed on her face for just a moment before she spoke, “Close your eyes, and get on your knees.”

Rarity quickly obliged once more, letting her eyes fall closed as she knelt down, sitting her rear on her lower legs as they were now fully bared to the plush carpet below. She pricked her ears up to hear the quiet noises of her Mistress moving about in the otherwise mostly silent room, only the faint hint of the main room’s sensual music coming through the closed doors. Mistress was clearly retrieving something from one of the racks--and based on its position, she guessed it was some sort of binding--before then approaching her lovely toy.

The simple presence of her Mistress was enough for Rarity’s breathing to pick up, and she could tell the Siren was taking her time to move over to her back, then lean down before grabbing her arms and pulling them up behind her back. Rarity moved her arms alongside the gentle tugs until her arms were pressed against each other, and then let her Mistress wrap a long leather strap around and around her arms, then tied it off so that her arms were now stuck there, unable to move in any meaningful way.

Next, Mistress Adagio crouched down and did much the same with her legs, but this time had longer, thicker strap that went around both the upper and lower portions of Rarity’s legs, completely locking them in that kneeling pose as well. And then, to top it all off, the Unicorn felt a cold ring of metal slide down her horn, and and icy chill ran down her spine as she felt her magic cut off from her.

Sighing with bliss, Rarity bit her lip at the familiar comfort of being helpless, and drew a sharp inhale through her nose as she felt her Mistress’s leather-gloved hands slide down her arms and then onto her hips, sliding around her rump and squeezing, forcing a slight gasp of surprise and pleasure from the bound mare. A quiet, low laugh from behind her made it clear just how much her Mistress enjoyed her toy quaking and gasping at these light touches alone, and then leaned forward to slide her fangs along Rarity’s neck, making her shudder and moan in desperate lust.

“You naughty little thing~” Mistress Adagio teased as her arms slid back up Rarity’s form, one going up and wrapping around her chest, pressing lightly at her breasts under the chilled leather, while her other arm went up further up the silky purple locks of Rarity’s mane, running her fingers through with a clear mischievous intent. “You always put on such a show in public, that you’re such a capital-L ‘Lady’, but...

“Here, your true nature is revealed.” A sudden yank of her Mistress’s hand pulled back at Rarity’s mane, making her shout out a mix of a yelp and a moan while her eyes shot open, only for her Mistress’s other arm to press down onto her tits, making her wince in pain. “Don’t open your eyes yet, petulant little toy,” She then commanded in disappointment, making Rarity quickly nod rapidly and shut her eyes once more.

Mistress’s hand still kept Rarity’s head pulled back, but her other arm slid up off the Unicorn’s breasts, its hand wandering and tickling at Rarity’s neck before sliding up to her maw, where those leather-clad fingers stuck themselves inside, forcing her mouth open and pulling at the stretchy side part of it. “Hmmm...” Mistress Adagio murmured, seeming thoughtful as she moved her fingers around the inside of her toy’s mouth, catching a lot of the saliva that was in there, “You’re already quite a slobbery mess, slut... I suppose we’ll need to do something about that, won’t we?”

Suddenly, all the sensations of her Mistress pressing up against her back, yanking at her mane, and sliding around in her maw, just vanished as the Siren pulled away, standing up and heading back to the far wall, not even needing to command her toy to keep her quiet. Rarity did need to take a moment to breathe now that her Mistress wasn’t quite literally breathing down her neck, her breaths hot and heavy while her chest heaved with lust, gulps of saliva and deeper breaths taken to try and calm herself back down before--

“Glmph!”

Rarity almost opened her eyes at the shock, wincing and forcing them closed while she felt something get shoved deep into her open maw, stuffing itself deep into her throat and getting fixed against her lips. She could quickly tell it was in the shape of a large dildo, but the straps that she soon felt against the side and back of her head made her aware it was a gag as well, one meant to make it very difficult to breathe, which it was already quite succeeding in.

“Hm,” Mistress Adagio paused in her tying the straps of the gag for a moment, “You seem quite comfortable with this one... perhaps I should switch it out for the larger one?” Rarity practically choked on the gag at the spot, and forced her head to keep still, knowing that shaking her head rapidly like she so desperately wanted to do would only make things worse. She could hear a quite laugh from her Mistress as she struggled to keep herself together, tears already starting to form in her eyes and trail down her face, no doubt taking her makeup with it and making her a desperate, slutty mess.

Soon enough, she feel the breathing of the Siren against her own face, the excited breaths of the dominant creature warming and dampening her face as she felt those purple eyes piercing into her very being, watching as she struggled in her binds, unable to move from her strenuous kneel or do anything with her horn. Still, Rarity wriggled in those binds, feeling sweat start to form across her body and make the leather binds stick against her, and made her feel somewhat uncomfortable, but she still thought--

“Gllrk!” She gagged on the dildo as she felt something press against the outside of her throat, and it quickly went away, keeping her on her toes as she tried to recover and prepare for when it came back. She almost gagged at when it did, still definitely wincing at the feeling, but at least she could tell it was her Mistress’s hand this time, and those cool fingers then slid across the large protrusion in her neck, repeatedly making Rarity feel like she was going to choke, but luckily she’d had enough practice to keep herself under control.

“Good, good...” Mistress spoke, seeming pleased by her self control, and Rarity felt a swell of pride and happiness as she let those words wash over her, but that was only before one of her Mistress’s arms went around to her toy’s backside and yanked on her tail.

Rarity immediately gagged on the dildo stuffed down her maw, and went into a coughing felt that was made very painful by that dildo, tears streaming harder out of her wide-open eyes and running down her face, her lungs burning from lack of air as she tried to calm herself back down, taking quite a while to stop coughing, but still desperately feeling the urge to from the way it pricked at her throat. Once she gained her senses back, she could hear the laughter of her Mistress enjoying her toy’s pain, and she soon added onto that with a snarky, “Oh, your mane and tail are as sensitive as always, hm?

“Don’t worry though,” Mistress Adagio then added, placing her free hand on Rarity’s chin and lifting her face up to stare directly into her eyes, “I won’t be yanking your ‘precious’ locks all the time; I have far more things I’d like to do...” Letting her eyes remain there for a moment as Rarity bent under the pressure of that gaze alone, watching in perturbed, yet excited fear as her Mistress didn’t correct her open eyes while her hands trailed down from Rarity’s chin and up from her tail, both sliding along the sensitive fur as they went until they traced up the small hills of the Unicorn’s breasts and arrived at her nipples.

Playful flicks of those malicious leather-bound fingers against Rarity’s sensitive nipples foretold the worse things to come, and she had a short while to huff and heave through her nostrils alone, flicking her eyes up for just a moment to see her Mistress’s gaze still affixed to her tits, utterly unaffected by her petulant toy watching her. After Mistress Adagio had her fun with just the nipples, she moved on to fully groping unabashedly at her toy’s breasts, fondling and squeezing them while their owner whimpered and flushed hard at the humiliating and enticing treatment.

“Your breasts really are quite lovely...” Mistress Adagio spoke, pulling Rarity’s attention back up to her face, where those purple eyes were still locked onto the marshmallows on the Unicorn’s chest, “You really should show them off more often. And, well,” She continued as her fingers traced some faint red lines present on the fleshy pillows, getting a mild wince or two of her toy before she suddenly pulled her hands away and got up.

Blinking repeatedly for a moment at the surprising action, Rarity then had to look up as her Mistress reached an arm behind her back and pulled something out, but she couldn’t see what it was until--

Fwi-crak!

--it flew at her breasts and struck them, cutting through the air and slicing just a tiny bit into her flesh, but enough to make her grunt heavily in pain, and gag again on the dildo still stuffed in her maw. However, she was forced to look up through it as she heard Mistress Adagio finish her statement with a borderline malevolent smirk, “They would definitely look better when tenderized.”

Fwi-crak! Fwee-crack!

Mistress quickly followed up her first swing of her short whip/flogger with another two, the second with a bit more build-up and landing even harder. Grunting and choking at the pain once more, Rarity felt the heat from the impacts radiate into the rest of her body, making her face start to feel like it was burning from her flush while her ears flickered up and down uncontrollably for a moment, eventually settling on folding down with a healthy blush to them as well.

“You can feel it already, can’t you?” Her Mistress then asked of her, trotting around Rarity with slow, plodding steps until she arrived at her back, and reached a hand out to slide along it, tracing her fingers across the many faint scars that littered the otherwise pristine mare’s flesh and fur. “Your body, so upkept and spoiled by your Canterlotian pampering, that this refreshing use of pain makes you excited. And not just mentally either...” A short chuckle escaped the Siren’s lips, and a slow, obvious inhale could be heard through her nostrils as she smelled the air, and Rarity quickly felt the chill whispering across the wetness between her thighs.

“I don’t even need to touch you there, and you’re already feeling its onset,” Mistress Adagio commented in amusement, and paused her words to whip again at her toy, this time striking her back.

Fwee-crak-k!

The tail of the whip streaked across Rarity’s tender flesh, marring it with yet another red line, but far clearer and more vibrant than the rest. She could feel her body react to that strike, the heat pouring out of the pseudo-wound and making her breathing yet shakier, and forcing more juice out of her nethers.

“It’s been quite some time since your last visit. I thought things may have been going better for you,” Mistress Adagio spoke, sounding oddly pensive as she pulled away from her toy, “As gorgeous as everyone knows I am, I know you were never here for just me...” Slowly walking back around to look Rarity in the eyes, their faces getting closer and closer as the Siren crouched before her toy, “You need this. This torment, this relief... this pain, this pleasure... all to get away from the stresses of your life.

“And yet,” Mistress continued with a grunt as she stood back up, placing her whip near Rarity’s face and watching her eyes lock onto it in a mix of fear and lust, “You keep diving face-first into that stress. You have your reasons for the job itself, but we both know there’s other ways of dealing with the stress it forces onto you. The Spa, your friends, and many other places of pleasure that are far closer, but you come here when it all reaches a boiling point. Here, where I bind you, choke you, insult you, and whip you...”

Rarity’s eyes went back to her Mistress’s, and they stared at each other for multiple seconds, understanding and empathy mixed in with their expressions of lustful fear and aroused dominance. “You love this,” Mistress continued, tracing her whip up along her toy’s jawbone, making her whole body shudder, “More than anything... You don’t just want to be a slut, you need to be my toy.”

Fwi-CRAK!

The loud, harsh sound of the whip echoed the tiniest bit across the room, Rarity jerking back from the pain of it slicing across her face, a strong mark no doubt made there as flames of lust poured once more through her body, forcing her to close her eyes for a couple seconds as she tried to process all the stuff flooding her mind. The immense pain that almost drew blood, the pleasure that made her want to orgasm on the spot--she shook her head, her Mistress still needed to be obeyed.

Looking back up to see her Mistress standing over her, that devious smirk still on her face, clearly entertained by how eager her toy was to please her, and she spoke, “So, let’s see just how good you are at being a senseless toy for my pleasure.” Rarity had little time to shudder while Mistress Adagio walked around her before she grabbed the locks of her purple mane again, and this time pulled her along the floor with that grasp, making Rarity wince and grunt in pain from her scalp getting pulled like that as well as how rear slid harshly along the carpet.

However, that was hardly the end of her treatment, as Mistress then pulled Rarity up by her mane to stand next to the Siren herself, though her toy’s legs being bound together as they were made it incredibly difficult to stay upright. Her Mistress kept her grip on her mane with one hand to keep her stable while her other hand went down and unknotted the strap around Rarity’s arms, unravelling it and pulling it away, leaving the mare in confused relief as she stretched her arms out for a moment to help her balance...

Only for them to get pulled right back away from her. One of her arms was quickly grabbed and then bound by a smooth rope, one she found oddly familiar and forced her to look up, where she saw those ropes she saw upon entering and now definitely knew the purpose of. Her other arm was soon to follow, and she was mostly left to balance with only help from the ropes as well as Mistress’s grasp still on her mane.

The strap around Rarity’s legs was soon removed, thankfully, but she already knew it wouldn’t be long before--

“Hrng?!” Rarity grunted in shock as she felt her entire body get lifted up, and after choking on the dildo still stuffed down her throat, she realized Mistress Adagio was lifting her with one arm. Her heartbeat picked up from its already pain and lust-stricken fever to begin to pound with drooling desire over the sheer strength of her beloved Mistress, the muscle of that arm bulging out through the leather wrapped around it and pressing into her back, lifting her until she was practically horizontal.

Rarity could tell the grip on her mane fell away, though only barely through her newly-rediscovered swooning, but at least she could see her Mistress’s other arm--the one that wasn’t bulging with power into her back, that is--pulling another rope attached to the ceiling to wrap and tie around one of her legs. Of course, that was then followed by the final rope pulled close and binding her other leg, before finally Rarity was left wholly hanging from the ceiling, Mistress Adagio’s strong arms then pulling away to leave her there.

With the reprieve of her Mistress’s body pressing against her own, Rarity closed her eyes for a moment to breath slowly, trying to calm her burgeoning craving and beating heart, but that was quickly cut off by the swift yanking out of the dildo in her maw by her Mistress, leaving her throat empty, slightly gaped, and quite sore. Gasping for a moment with the newfound ability to properly breathe, Rarity then had to cough dryly for a short while, her quickly evacuated throat being rather pained, but when she was finally done and breathing heavily from exhaustion, she looked over to see Mistress Adagio still standing next to her suspended form, smirking at her with amusement and.. a layer of sympathy.

“I’m no savage; I do treat my toys with care, you know,” Mistress said calmly and reassuringly, making Rarity nod through her exhaustion as she continued to catch her breath. “Of course, I still want your mouth open to hear just how loud you can moan...”

Rarity bit her lip with the giddiness from that feeling of being owned and treasured, yet used and played with in ways she’d never imagined before each time she was there. Her Mistress only strengthened that feeling as her hands returned to caress her toy’s form, starting at Rarity’s hips and sliding up and around across her fur and flesh up to grope at her breasts, where they then started to squeeze them, softly at first, but quickly getting stronger and stronger.

“Nnnnnnnnnggh!” Rarity nearly squealed out from the pressure, pressing her eyes closed as she felt her boobs get clamped, the usual pleasure turning to pain, but burning no less lust into her mind. However, it didn’t last for too long, as Mistress Adagio pulled away for a moment, letting her toy gasp and breathe heavily in reprieve, but then cut that off with a slap across those tits with her hand.

Grunting and gasping from the impacts, Rarity tried to fix her now wide-eyed gaze on her Mistress, but quickly found that the Siren was gone from her side, and she was just and quick to find out where she had gone to.

“NNNGGAAAAAAH!!” The Unicorn screamed out as her tail was yanked again by her Mistress, her whole body jerking downward and folding slightly inwards from within her bindings, but like with everything else, her carefully maintained and sensitive locks getting so mangled and tussled enflamed her desire further. In fact...

The deep, sensuous chuckling of her Mistress’s amusement breathed across her bare pussy, making Rarity shudder from how chilly it suddenly felt there, and she could immediately tell that it was because she was dripping with arousal. A far deeper shudder crept up through her body as she felt something far wetter lick across her snatch, and a breathy moan escaped her lips, and grew into a loud, relieved groan of pleasure as her Mistress’s tongue entered her.

That long, wet, slithering tongue of the Siren went deeper and deeper inside of Rarity’s vagina, and it felt so filling with that length and girth penetrating her, her Mistress letting up on the relentless pain for just a moment to let her sigh as the pleasure flooded through her body, soothing her aches and tension. The mare knew this serenity wouldn’t last, but sought to take in as much as she could for the time it would be there before the torment returned to finally extinguish any remnant of tension that remained within her.

For a short while, Rarity let herself bathe in that rising tide of pleasure, the metaphorical balloon in her crotch inflating with each slithering motion of her Mistress’s impeccably skilled tongue, low moans and groans flowing out from her lips into the slowly heating up air.

Of course though, that tide continued to rise and that balloon kept inflating, but Mistress Adagio simply remained at her current pace, tongue licking and lapping around inside her toy’s tunnel, clearly aware of what she was doing and deciding not to help the mare through her burning lust. That was when Rarity started to get unsettled by the pleasure, figuring out that it was the twisting of that familiar, relieving sensation into a slow, methodical torment that was meant to truly get her, and she felt the tide start to plateau at the edge of her orgasm.

Rarity could almost feel her Mistress’s smirk against her pussy while her tongue slowed down, each motion of it now even more deliberate and careful, seeming almost tentative as if they were stoking a flame, which was far from inaccurate. Her tension kept rising though, the point of bursting coming ever closer as she tried to desperately reach for it, trying to feel the pleasure and submerse herself in it again to shoot past her Mistress’s denial, but she knew it was futile from the start.

Mistress Adagio soon pulled her tongue out of her toy as she started to whine and whimper, becoming more desperate with each passing moment and being unable to stop her own body from trying to push forward to keep that tongue inside, but her Mistress was one step ahead of her. Those leather-clad hands grabbed onto Rarity’s thighs and kept them in place as she continued to slide her tongue back out, seemingly unbothered by her toy’s pitiful attempts to relieve herself, but still kept little flicks of her tongue in to push said toy even further to the edge.

By that point, Rarity started to feel like she was going to explode with pleasure, her orgasm just outside of her reach in a way that she’d reach in less than a few seconds of masturbation on her own, but it was kept there, nudged closer and closer in the most tormenting manner possible. Sweat was now forming on her brow and trailing down her face from that torment, repeated grunts and moans forced out through her clenched teeth as she continued to try and push forth to reach that ecstasy, but it only furthered her own frustration.

“Puh-please...” She couldn’t help but croak out, her voice dry and needy as she tried pull her head up to look down at her Mistress between her legs, only really catching a glimpse of that poofy orange mane past her knees.

A cool, decidedly unfulfilling breath was let out across her very wet pussy, and a couple flicks of Mistress Adagio’s tongue set Rarity yet further on edge for what the Siren would eventually say. “Do you really think...” That sensuous, casually dominating voice came out, though a bit muddled due to presumably having her tongue still sticking out of her mouth, “...that I would let you have that so easily?”

The deep, foreboding chuckle made its way out of the Siren’s maw once again, inciting true fear into the mare in her grasp, who could only shudder as she felt that long tongue start to lick across the inside of one of her thighs, which still managed to draw the tension in her loins higher, but made her no closer to actually orgasming. In fact, as her Mistress slithered her slick tongue over her thighs and around her crotch, but never touching her pussy, the tension down there was so unbelievably tight and hot that Rarity started to feel like she passed over that edge of orgasm, yet somehow hadn’t actually cum yet.

“Nnnnnnnnngh...” The Unicorn groaned out in a bewildered concoction of pain and pleasure, feeling like whatever dark magic her Siren Mistress had access to had literally stopped her from being able to orgasm, allowing her tension to build and build and build. Sweat was pouring down her face now, her heart beating at a maddening pace, her entire body feeling like it was on fire, with the hearth being those strokes of saliva across her crotch, where the magic seal was crafted.

The sharp grin on Mistress Adagio’s face made it clear just how much she enjoyed watching the torment playing out on her toy’s face, especially given something else; “Oh, please, don’t act like you don’t enjoy this.” Her grip on Rarity’s thighs grew firmer as she continued to lap around her toy’s snatch, tickling her pearlescent coat and adding with another layer of teasing torment, “After all, this is what you came here for...”

However, Rarity could still only writhe and moan helplessly in her Mistress’s grasp, her orgasm utterly denied from her for what felt like several minutes, and her Mistress simply continued to watch her for a moment, then eventually sighed in a mix of amusement and disappointment and said, “Very well. I do suppose I can let you have actual relief...”

And with that, she finally pulled her tongue off her toy’s thighs and positioned its tip right in front of the Unicorn’s fluid-smattered and rapidly winking pussy, and then plunged right in.

“GAH-FUUUCK!!!” Rarity screamed in ecstasy, feeling that seal on her loins finally shatter and her orgasm flood over her like a tidal wave, her vision blurring into a white mess while her pussy exploded with marecum, the sticky fluid splattering out all over Mistress Adagio’s face. The sheer volume was enough to take even the amphibian Siren aback, as even the many past sessions they’ve had weren’t enough to curb her surprise at how incredibly pent-up her current toy could get.

Rarity could process it even less though, as her mind felt like it was melting under the force of her orgasm, her pussy convulsing and erupting as heat and pleasure tore through her body while it writhed and shuddered violently in her binds. It all kept going and going, the concept of time itself shattering in her mind, leaving her unable to tell whether her orgasm was lasting either several seconds or multiple hours, but the white of her vision slowly darkened, the heat and convulsions slowly fading from her senses.

Eventually, that darkness and numbness encapsulated her entire form, and it wasn’t long before she felt her awareness in general slipping under, any ability to think or even feel her own body going down and down until... she had completely blacked out.

Author's Note

Sirens are a little unusual to anthro, so here’s a ref pic in case you can’t quite visualize Adagio properly:
