Dirty Deeds Dusk's Dick's Done

“Trixie wishes to know if your math is as bad as your judgement.”

“Not in the mood for this, Lula-”

“Because we’ve got two cars here now.”

It wasn’t often in Trixie’s modern life - ping-ponging from the Great and Powerful apple of Equestria’s eye to the fly in it’s fickle feedbag - that she could claim to surprise somepony. Entertain them, oh yes. Dazzle them? Well, only one group of girls excelled her in that area. Even humble then? Oooh, nothing got the points of her well-developed funbags harder faster.

But this time, seeing the Tempest Shadow, ex-corporate headhuntress turn an even darker shade of red over the two Siren-driven cars pulling up to their motley car-wash? That was a surprise. A genuine, thrilling surprise. And Trixie couldn’t keep away the cheekiness in her grin now.

Then again, wild horses couldn't do that.

“Heya, Trixie!”

That chirpy tone, however, made Trixie’s eyes narrow licentiously. Sonata Dusk was calling to the showpony, almost invisible behind the poofy curls and magnetic grin of the driving Adagio. She was all Trixie could see, though.

Fluttering her fingers at the bluenette Siren, Trixie cocked her hips. It was finally showtime. “And just what brings you Sirens to our little charity event? Besides the obvious?”

“Careful, Lulamoon.” Ignoring the curl in Trixie’s smile at her last name, Adagio wasn’t disturbed in the least as she rolled from the driver's seat. “Your chest’s about to pop - don’t let that swelled head follow suit.”

Starlight’s hand clamped over Trixie’s mouth before she could fire back more invectives at Adagio. Murmurs of ‘piss-colored airbag you call hai-’ and ‘kiss my Great and Powerful a-’ seeped around those purplish digits, however.

“Trixie - just handle the Dazzlings’ car, okay?” Starlight pleaded. “You’re already up to your tits in noise complaints, let’s try to keep it from getting up to your horn.”

Trixie’s eyes rolled, before she let out a defeated sigh. “When you pop it with Adagio.” she relented.

Starlight turned near-purple from blushing. “W-what? I’m not g-gonna roll over for Adagio like that-I mean, she’s not even that hot - I mean who told you?”

Trixie’s eyebrows were raised so high, they could almost be lost in the white waves of her mane. “Trixie meant... pop her in the jaw, Starlight.” Then it was joined by a wicked grin as Starlight shrank in her booth’s seat. “But go on - how long has this tuneless wonder been on your mind?”

A sharp smack to her scantily denim covered-rump made the showmare tense up with a hiss. Turning back to Adagio, Trixie was about to growl. Until she noticed Adagio’s face only inches from hers - and the waves of citrusy perfume soothing her snout.

“Oop! So sorry, Lulamoon,” she purred, swaying her hips as she eyed up Trixie. “Just wanted to get my payment for the cleaning this year. That cool with you?”

Trixie drew in an indignant breath. Gems or not, Adagio apparently did have some hypnotic pull to her stare. But Trixie was undeterred by this - she was the Great and Powerful, it’d take far more than a pair of lustrous bedroom eyes to trip up as talented a magic-maker as her! So what if Adagio’s eyes were traveling over her wonderfully bulging rack… her almost transparent white tee… or her jean shorts that were thin enough to count as a second belt?

“Trixie?” A pair of snapping fingers from Adagio brought both the showmare and Starlight out of their dreamy reveries. “Regular wash, seat shine, no wax. Ready when you two are.”

“Oh. S-silly me, I’ll… take the job,” Trixie huffed, feeling the color rise to her cheeks as well as she shot the doe-eyed Sonata a guilty look. “I’ll just get started on your… what name did you give this newfound smog machine again?”

“Mako Shark Coltvette. Thought you’d like the name...”

Trixie’s blush grew more vivid as her legs slid together - suddenly slicker than they were five minutes ago. Adagio was already privy to so many of the reasons Trixie and Sonata were the talk of the town! Did she have a checklist of all the showmare’s fetishes too?

“... am I right, Lulamoon?”

Back came the curl in Adagio’s lip. Whatever Starlight saw in this arrogant buttercup, it was no longer of concern to Trixie. “Then Trixie will take her leave - ” And the furious clop of hooves on pavement deafened Trixie to the world again.

Everything but Sonata. “Sorry about that Trix," was the first thing the showpony heard as she stalked over to the car. “I told Dagi you never liked that name, but-”

“It does not affect Trixie,” Trixie lied. That Sonata broke into such a cherubic grin over it made the showpony’s heart twist uncomfortably. “How has it been for you?”

“Oh, wonderful! So even though we lost a lot of the cash we had last night, Adagio got this really new job this morning! See, she’s going to be this spokesiren for a new range of herbal energy bars for this new up-and-up free spirit - can't remember the first name, but the last one’s Hugger - and since we’re offering to shoot at our place, we get al the money they’d spend on a stu-”

“Sonata,” Trixie restrained the urge to snap fingers in the Siren’s face. “I meant how has taking in Trixie’s lessons been going.”

“Oooh, yeah. “ Sonata pondered. "I… think we were quiet enough last night. Adagio only banged on our door four times, ‘member?”

Trixie’s sex dripped hungrily at the remembrance; so there was a reason Adagio was so snotty today, wasn’t there? Tucking a finger underneath Sonata’s chin, Trixie pored over her love’s attire - which consisted mainly of a burgundy hoodie. Even then, Sonata Dusk seemed so subtle. Despite all the pomp and flair of a Dazzling burning bright behind her eyes, it never seemed to travel beyond it much since there was a gem guiding her voice to draw everypony into her thrall.

All affection, no direction.

Trixie, unfortunately, could relate.

Even when she’d been the main-event, she’d learned hard and fast how fleeting it was without pure magical heft. And even when she found her ways back, it never lasted long. It was just like Sonata’s station, wasn’t it? Always living in the shadows of their better halves.

Or triplets, in Sonata’s case.

“That’s okay, Sonata.” Trixie purred, snapping back to planet Equus. “We can work more on that after this blasted car wash thing is over.

“Sure you don’t want I should get the last bits of Shark Week down on ColtecoVision?” Sonata asked. “I’d be quick about it and everything. Plus…. We could get some distance from Adagio.”

“No.” Suddenly, the iron-hard edge in Trixie’s voice returned. “That cheese puff has never intimidated Trixie before, and she will not do so with anyone under her wing.”

Sonata blinked. “But you don’t have-”

“Sonata. We have been over metaphors.”

Realization struck the Siren, and she nodded. “Oh! Like when you said Lil’ Sonata needed to wear this hoodie to keep Big Sonata hidden when we got together for our playdates?”

“Absolutely. Speaking off. How is she?”

‘Is that doubt plaguing Sonata’s voice?’’ Thought Trixie. Usually the bit lip was a clue - but that also came about when Sonata found out about shark sushi too, so false positives were abound.

Thankfully, this Siren was happy to elaborate. “Yeah, aaaabout that. Dagi and Aria wanted me to talk to you-”

“-aaand nevermind, Trixie will see for herself.” muttered the showmare, pinching the bridge of her nose.

“Ooooh, nice. S'like you’re letting me see how great you look!”

Trixie was again ready to complain that she hadn’t dressed like this for Sonata, per se. But as her eyes swept over the scraps of clothing clinging to her Great and Powerful body; well who was she to counter a self-evident? fact.

Ironically enough, it was after her second defeat to Twilight that Trixie started gaining some more… natural gifts. Whether it was the Alicorn Amulet, or just her body giving her a freebie, she’d ballooned in all the right places. Breasts so large you could balance oranges on them, an hourglass figure currently hid by a tissue-thin tee, and by fuck an increased sexual appetite. Especially for dicks big enough to wreck her winking holes.

But enough about Big Sonata.

“Just hold on while Trixie tackles this Mako.” And with sponge in hand, the showmare went to work.

For the first few minutes, Trixie silently works hard, working her hands and sudsy tools over the front of this Mako. Soon, reflections of her started showing in every shiny surface she could reach. It was doing wonders for her pride, and for shoving the thoughts of that annoyingly alluring Adagio out of her mind.

But perhaps Sonata was doing a better job of that already. The second that Trixie eyes returned to the petite Siren, she almost melted on the spot. Sonata, between tugging on the zipper to her hoodie and adjusting the seats, was locking her gaze on Trixie’s impressive rack; whether from jealousy or jubilance, Trixie could not tell. Sonata was many things, but expressive was a descriptor that had taken a pounding as of late.

Or gave Trixie a pounding, either-por.

Regardless, Trixie decided to reward Sonata for her ogling. Knowing that she could snap her fingers or sway her hips and turn a Siren that once ran schools into a horn-dog? Super hot. So Trixie let her breasts rest against the black hood, marveling at how easily her cleavage pooled under her chin. Deliberately, Trixie used her wonderful funbags as the sponges to soak up the leftover suds, purring lightly at the cold soaking her shirt and soothing her soul.

Sonata was soon rocking back and forth in her chair, and her hoodie's hem stuck out at angles a normal observer would see as weird. Not Trixie; for her, she knew this was the state she wanted to see Sonata in the most. And now it was time to claim her own reward; Adagio’s seat-shining requests could wait.

Especially since Adagio was busy making a seat out of the shuddering Starlight several meters away from them.

“So, Sonata…” Trixie purred, letting the works fall over her like waves of sea spray, and tossing back several of her white locks to further complement them. “Did Trixie do right by your car?”

“Uh huh.” Sonata wet her lips. “I’d like to… well, some of my clothes are getting wet too.” Indeed, a telling dark pool of soaked fabric was creeping up her hoodie, the sight making Trixie’s hips jerk toward the Siren. “Could I… possibly get out of them? S-since my sisters aren’t around, and…”

“That's what you want?” Trixie purred, feeling that sopping warmth pool under her shorts again. She leaned forward again, loving how Sonata’s bitten lip got redder the more Trixie’s cleavage squashed against the hood. “Then let's see what’s gotten them all wet and sticky.”

Sonata silently nodded, slowly pulling herself from the passenger seat - and showing a hint of her luscious slim legs, currents of rippling blue only broken by the black of her legwarmers and the hem of her hoodie. With a slight curve of naughtiness tainting Sonata's smile, that puffy scrap of clothing was soon pulled up and over her head.

Now it was Trixie’s turn to stare in drooling disbelief. Sonata was clad in nothing but black netting from the crotch up, the material shiny as it hugged her arms and perky chest tight. It was just enough to cover the swell of her breasts, too; that and the knitted ‘S D’ stamped out in the middle of that makeshift boob-tube. Her shorts were no different - the solid stripes running down the sides only serving to further outline her sleek curves and ass. And a metallic clef note, slim and shiny, dangled out from Sonata’s belly button, teasingly pushing at the hem of those shorts.

But it was what was south of the equator that got Trixie's attention the most. Curled in an almost certainly uncomfortable package at the front of those netting shorts was the thickest futacock Trixie had ever seen. Even now, stars flew through Trixie's mind like a flock of tophat-spawned doves: Fourteen inches flaccid. Nearly as thick as Sonata’s arm. Veins as thick as Trixie’s fingernails. As hard to the touch as Trixie’s hooves.

And every bit as opulent as a dragon’s hoard too, what with that ruby-red gem tipping the bulb of that foot-and-a-half long fucklog.

“Sonata…” Trixie breathed that name with such succor, and yet it felt so miniscule next to Sonata’s generosity in this moment.

“I thought it’d make a good Shark Week present, Trixie. All this.” And so thoughtful, too! Sonata knew just how much Trixie treasured such wonderfully wrapped presents! “Is it a good enough catch of the day for you?”

Before Trixie could speak, Sonata’s fingers swept down over her own taut stomach, the dips and curves of baby-blue muscle fluttering at the touch. Trixie would have shorn off her horn to be those fingers right now. But as it was, the feel of suds seeping into her tits and the shock of the sight before her rooted the showpony to the spot.

Thankfully, her tongue was not so frozen. “Show Trixie more,” she throatily ordered.

Despite how sinfully endowed Sonata was, despite the hypnotic lull she had on the showpony, she nodded. It was but one of the many reasons why Trixie loved being with Sonata, and not just having this Siren in her. So strapping, yet so eager. So mouth-watering, yet so meek.

Of course, Trixie was slowly training out that last trait in Sonata.

And it showed in the sultry dance Sonata pulled off for Trixie. She’d always had the figure - she was a Dazzling, after all - but what Trixie had shown her through endless sessions at Shores’s studios would make Sonata a center-stage model now.

Slowly, Sonata turned her back to Trixie, letting an exaggerated roll of her head send her sapphire locks tumbling over her back. Trixie licked her lips at the sight, likening it to waves lapping on a bleached shore. Of course, her eyes were then locked on Sonata's hand, deliberate and dainty as it circled her cocked hip. Then Sonata kneeled as she continued fondling her pert ass, her face laid to the chrome of the car as she wistfully sighed.

Trixie instinctually jutted her hips at the sight, her pussy winking and gushing underneath her skimpy shorts.

Then Sonata rolled so her back was to the lip of the Mako, and her hands traveled upwards to her breasts, pinching and crushing her rigid nipples. Sonata was lost in the rough treatment of her tits; catlike mewls and meeps bubbled from her lips.

And as if to complement her musical bellybutton piercing, each Sonata nipple-pinc synchronized perfectly with Trixie’s air humping.

Soon, both Trixie and Sonata's legs were trickling with pre, and the Siren took that opportunity to foreshadow just how their session would end. Slipping a finger into her mouth, pumping it back and forth like a pro, Sonata let her other hand drift down to flick her cock out of her netting shorts. It was nearly a straight arrow at that point, the jewel at its tip lost in the river of pre running down its girth.

The finger fucking Sonata’s plush lips soon shot out, a trail of saliva soon snapping almost as fast as Trixie’s sanity did. Sonata didn’t seem to notice that, settling her free hand behind her head as she swung her hips - and mare-breaking dick - in lazy loops. Her legs jerked and dipped, meandering to a tune that Trixie could follow without a single musical note.

By the tenth second of Sonata’s silent sashaying, it was too much for the showpony.

Caught midway between a bend back over the car hood, Sonata almost hopped onto it in surprise when she felt an absolute furnace close around her exposed cock. Whipping her head down, she almost came on the spot at the sight of Trixie - Double-D packing, Daisy-Duke-short wearing Trixie - slurping the tip of her colossal cock like it was chum. Now it was the Siren rooted to the spot, watching as Trixie’s hand stroked every part of her battering ram she couldn’t immediately suck.

In a direct contrast to the sensual show she’d given Trixie earlier, Sonata roughly fisted a hand in Trixie's mane. Slowly, thumbing the albino curls, Sonata watched the showpony work her tongue around her. Sparks, rich and vibrant, collected at the tip of Trixie’s horn in glee.

But Trixie wanted more. Even now, with her sinuses and throat clogged with cockmeat and ballmusk, she knew Sonata could be dirtier. Oh, not verbally; that was the final frontier not even the Great and Powerful had breached yet. Sonata was really quiet in the sack, surprisingly likely after a lifetime of catching the scraps from her far more assertive Siren sisters’ escapades.

But Trixie had worked on that front too - and with a flutter of her eyelashes, the shuddering Sonata got the message.

“Y-you’re sure?” yelped Sonata, a particularly needy slurp from Trixie making her voice hitch.

Trixie didn’t respond with words, and didn't want to. Not with this titanic twatbuster just starting to tap the back of her throat. So Trixie just pulled her lips back from that shiny head with a lewd pop, then kissed the bejeweled tip sloppily, tapping it against her cheek in anticipation.

Even if Sonata was in doubt, her own dwindling sanity was overruling it. Her grip on Trixie’s mane got tighter, and she started guiding the showpony's mouth-swipes on her erection. The grin stretched around Sonata’s tool spurred her own, and soon she’d gotten Trixie snout right against her crotch. Her balls were dancing on Trixie’s chin, her bellybutton ornament curled around the unicorn's horn.

Just as Trixie was about to retract to feel that nerve-sparking joy of deepthroating Sonata again… she couldn’t. Sonata was holding her flush, mouth-to-crotch, a burbling moan slipping from her mouth. It was the first time Sonata had exerted her will on the showpony, keeping her from doing anything but drooling over her throat-impaling member.

And nothing was hotter to Trixie than that.

Slipping one hand down to stroke at her gushing clit, Trixie let Sonata swivel her hips until her cock popped out of Trixie’s abused mouth. Again and again, Sonata swabbed Trixie’s mouth with her futadick, little ‘umph’s and ‘yes’s spilling forth as she caught hints of Trixie fingering herself to this debauchery. Between the sloshing noises of Trixie’s lips being plundered - both of them - it was easy to lose oneself in the spectacle.

But Trixie shot over that peak first. On a particularly brutal cock-thrust into her throat, her snatch-rubbing finally struck paydirt, and her loins gushed waves upon waves of succulent maresap over her trembling legs. The vibrations from Trixie’s throat as she moaned made Sonata’s eyes widen, and she yanked her tool from Trixie’s throat, despite the grin that rough exit gave her.

It wasn’t just from fears of choking out the showmare, either.

“Trixie, I’m so sorry, I almost came down your throat and I know you always hate that please for-”

But one look at Trixie’s face, and Sonata’s apology died on her lips. Trixie, despite the tracking stains of her makeup, couldn’t have looked happier. She was still kissing at the tip of the Siren's shaft straining before her, slinging her tongue around her taut nutsack, grinding her horn against her girth. Trixie’s t-shirt was damp with far more than soap-water now, and the strings of saliva connecting it to her mouth looked like manna to Sonata’s suddenly parched throat.

Slowly, Sonata's thumbs crept down to Trixie’s mouth, and she deliriously slurped on them too, the lewd noises shuttling away any restraint Sonata may have had. Sonata swiftly pulled her digits in opposite directions, fish-hooking Trixie’s mouth into a smile and grinning ferally at the sight of Trixie’s wagging tongue.

On jello-like knees, Trixie finally stood to match Sonata’s smoldering eyes. Just as she was about to loom over the Siren, a sharp smack to her heart-shaped rump made her yelp her bliss into the collarbone of the Siren. Soon, Sonata’s dainty hands were all over her ass: sliding her shorts down over her cheeks, snapping the bands of her violet g-string against her hips, and flitting through the locks of her flagging tail.

Trixie wasn't idle, either. Her Great and Powerful hand found its way back around the girth of Sonata’s tool - now so achingly thick her fingertips couldn’t meet - and pumped it in up and down. Not too tightly though; that would keep her from feeling the blood thrum around those pulsing veins. And from hearing Sonata’s syrupy moans trickling over her head, Trixie knowing she wanted to clamp over another part of her undulating Siren, too.

Quickly, Trixie craned her head forward and shoved her tongue down Sonata’s throat, reveling in the new moan she drank in from their kiss. Again, she found herself surprised by the normally passive futa, as two of Sonata's fingers suddenly buried themselves inside Trixie’s shorts, greedily nudging her thong out of the way. Trixie tried to kiss her harder, made her job messier, but Sonata would not be denied this afternoon. Immediately after, Trixie screamed down her mate's throat as Sonata's deft fingers plunged into her cum-sticky depths.

They stayed like this for a while, humping into each other while sucking the air from each other’s lips. Sonata’s kisses grew more desperate with each passing second, her supple thrusts into Trixie’s slippery hand starting to bring her to the edge. Soon, her palm pulled back - enough to expose Trixie’s winking pink pussy past the flaps of her jean shorts.

As Trixie would soon find out, it was because Sonata was going for a different target.

“Oooooh…” panted Trixie, the cool air hitting her sensitive clit almost too mind-bending for her to make words. Almost. “Soooo goo-sweet fuck, Sonata!”

Sonata, the ever-thinking pervert, slid her shaft right into that gap her hand made, brushing her colossal cumpipe’s shaft against the lips of Trixie’s pussy. The burgeoning heat both girls were met with made them throw their heads back in a shared moan. Sonata’s resumed humping of that carnal cubby turned them into purring piles of goo then and there.

Soon, Sonata was leaning against Trixie’s generous chest, and the showpony was laid back against the car’s side, losing themselves to their mutual madness. Trixie, past her obscenely loud moans, could feel her edge approach as she flicked her hips ceaselessly against the Siren serenading her. But in the deepest recesses of her mind, she heard something that hinted at a different conclusion; Sonata’s meeps, short and sweet, were turning into growls as she sank against Trixie’s neck. And suddenly, the Great and Powerful Trixie had an idea.

Waiting until the crook of Sonata’s neck was within mouth-range, Trixie lazily sucked against the aquamarine skin. She’d given herself over to Sonata’s licentious thrusts a while ago, using the sparks shooting through her from that cock grinding against her intimate parts to keep her edging. But this was time for something daring; because she was not going to cum twice before this pipe-toting siren did.

Again, anyways.

And Trixie knew she'd found her mark when she sank her teeth into the jamb of Sonata’s neck. It was a habit brought about by her other, more trouble-starting habit; being a screamer. Yet for Sonata, it was just the edge her fuckbuddy needed to climax, shooting a sizzling stream of seed against Trixie’s puffy lower lips. Soon, Trixie’s sodden jeans were like a basin, holding in the gooey waves of Sonata spunk. Sonata, a squeaking mess already, was thrashing and squirting in the suffocating grip Trixie had around her.

Eventually, the shocks receded enough for Sonata to recline back, letting her virile pillar balance against Trixie’s denim-clad hip. It also allowed time for Trixie to gasp at how phenomenally fucking rock-hard Sonata still was.

“Shit, Sonata,” Trixie whispered, bracing her hands on the hard hood. “Trixie never knew you could stay so hard, so long.”

“I…” Sonata gulped. “ I always was. J-just never knew how long before, because you always came…” Then Sonata's hands flew to her mouth, realizing how her next words would sound. Far be it from her to call Trixie a minute mare. Especially since every minute next to this voluptuous cock-craver felt like nirvana.

Trixie could guess though, and another idea started flooding its way into her fuck-drunk mind.

“That so?” she said, closing her hips around the flood of jizz basting her thighs. “Then Trixie challenges you to a contest.”

“Ooo! A contest!” And back came that cherub-like spirit of Sonata, clasping her hands as hearts danced in her eyes. “What kind? “

“Last girl standing wins, of course,” purred Trixie, pushing herself off of the car as she spoke. “And since you’ve been taught so well by the Great and Powerful-oh!”

Too well it seemed, as Sonata had taken initiative by shoving Trixie’s shorts down to her knees in one stroke. “Like this, right?” she asked, her hands roaming over the juicy booty of her shuddering showmare mate.

Trixie soon sucked in her lip, thrilled at the sight of Sonata becoming so... take-charge. “Y-yes, Sonata….” Trixie trilled. “Just like that. Spread those lips too - I wanna make sure I can fit all of you.”

Trixie’s authority was waning with every second the Siren touched her, yet Sonata followed her command all the same. Her hips canted when Sonata slowly pried apart her cum-stuffed pussy lips, the friction making her tail twitch and slap at the intruding hand. Not to tell her to stop, Celestia no, but to feel those digits press harder against her dripping snatch.

Because fuck if Trixie’s hands were doing anything but scrabbling over the smooth expanse of the car hood. “Sonata…” she hissed, idly remembering the job she was supposed to be doing. “Put it in or let Trixie take over. Your -ah!- your teasing’ll wreck your ride.”

Sonata shivered behind the crouched Trixie. Shucking off her netting shorts, she pulled herself flush to Trixie’s cum-stained rump. Trixie was busy peeling back a layer of clothing, herself - her drenched top now hung around her neck like a collar, letting her D-cup delights spring free into the sunbaked sheen of the Mako’s hood.

Suddenly, the same feeling flashed through both girls' heads as Sonata saw Trixie shoot back a toothy grin; her limbs straight but shaking against the pussy-stroking by the petite Siren.

Trixie was draped over this car.

Dripping with water and raw, liquified lust.

As blue as a prized tuna.

And every bit as delectable in the now-predatory eyes of Sonata.

Trixie’s tail flagged higher at the sight, bringing her ass further up to tap against Sonata’s throbbing sperm-stack.

With a fitful nod, Sonata finally mounted her special showpony. One slow thrust later, she found herself buried in the wet walls of Trixie, her mouth jutting open at how unbearably tight she was. It almost made Trixie’s hand feel like a throw pillow. Compared to what Sonta was wedging her way into - the slippery folds, the tangy strings of maresap - this cunt was a silk-lined sponge.

One that made Sonata never want to leave that tightening twat.

And yet she did, as Sonata’s slim hips snapped back and forth into the braying mare before her. Trixie found herself being pushed further and further up against the car hood, feeling the thin metal bend and sway under her bucking body. Trixie was certain it would probably leave dents. She was also certain she could care less as long as Sonata was ruthlessly rutting her.

For once, the Siren was starting rough! Was it Trixie’s longer-than-normal cock-teasing? Did Sonata really get going mold Trixie’s body to its limits, rather than Trixie taking charge? There was only one to find out.

Trixie had to make this contest worth Sonata's complete focus.

Leaning on one elbow - and moaning at how the shift made Sonata’s glorious erection grind right against her G-spot - Trixie pinched one of her ballooning breasts. Taking pride in the sensual shocks it sent through her - and how sensitive her nipples felt to her touch - she brought it to her pursed lips. Trixie almost melted at the keening groan Sonata let out at the sight, fucking the unicorn harder against the Mako as her own primal urges surged.

“Y-you ca-mmmphfuckyes- do it too,” Trixie cooed against her own hardening tit, tilting it in Sonata’s direction.

That invitation would not go unanswered. Sonata’s cry as she lunged forward to slurp in that rock-hard nipple was almost bestial. Her hips followed suit, pistoning even harder against Trixie’s rippling cheeks.

But her noises still didn't compare to Trixie’s wanton wails. She was certain that Aria and Tempest would have come barreling into an embarrassing sight (for them, anyways) had she not seen Tempest snogging Aria’s fucklog seconds ago. But Trixie damn well wasn’t silent in the face of this reprieve; begging Sonata to go “faster faster faster” as she watched the Siren suck and fuck at once.

Sonata’s titwork finished with a meaty pop as she sought out Trixie’s lips again. But this time, Trixie was in the mood for something more lasting than a lip-bruising kiss. Sonata was screwing her Great and Powerful brains out, and Trixie wanted to at least try to return the sensation.

So she dipped past those questing blue lips of Sonata and bit hard into the lobe of the futa's ear.

“T-Trixie, shit, oh shit~” And soon there wasn’t a spot on Sonata's cheek or ear that Trixie wasn’t biting as they thrust against one another. The squeaks of the sudsy sponge as Trixie’s right hand curled around it, the squishing of Trixie’s clit as Sonata’s hand teased its nub - it was too much.

This time, both girls came, though the totally ravished Trixie was first over the mountaintop. The dribble around Sonata’s mammoth shaft turned into a waterfall as she moaned and thrashed uncontrollably, smiling deliriously in the sight of her world shattering into white. Trixie almost missed the feel of Sonata’s seed caulking her insides even whiter, leaving her insides feeling packed and warm as it shot out of her pussy.

With a heaving yank, Sonata finally freed herself from Trixie’s seed-packed slit. A torrent of heavenly fuckbatter spewed out from that hole, staining the ground and making Sonata’s jaw drop as she braced her arms against the passenger-side door of the car.

Trixie, after hearing the click of that door opening and Sonata slumping right into the squishy seat, smirked deviously. “Done already, Sonata?”

Only several whistling wheezes answer her. If a push she noted felt more sluggish than it looked, Trixie sauntered over to Sonata, looking to comfort the clearly humbled Siren.

Then she was yanked in by a spindly hand, right onto Sonata.

“Not even close.”

It was Trixie’s only warning. Sonata gripped her ramrod with one hand, aimed it at Trixie’s stuffed clit, and pushed up. Velveteen walls clamped over their regained prize, and Trixie’s gasp turned into a shattering wail as she was jackhammered on her girlfriend’s lap.

Her hands scrambled for purchase on the edge of the car’s roof, and when she found it, she shot Sonata an absolutely manic smirk. “G-good, job…. Sona… you’re so relent… relent... damn it, just r-rut Trixie!”

Her wettest wish was granted. One of Sonata's hands anchored in the headrest of the passenger seat they were defiling with every squirting thrust. The other was sucking three of her fingers, eyes brimming with want at the sight of Trixie’s hypnotic rump shaking in her lap.

Over and over, faster and faster, Trixie was becoming a blue blur over Sonata’s pounding thrusts. The hiss of the seat under them was far more appealing to her than the squeaks from the Mako’s hood. But Sonata was the true draw of this carnal show, the muffled squeaks she gave out proof that she was fucking her own face with… something. Something Trixie couldn’t see, for her position atop the fuckpole of Sonata did not afford her the angle to.

Trixie certainly felt it though, the second a slick digit prodded at her puckered dock.

Howling like a lunatic, Trixie ground to a halt against Sonata’s crotch. Thank goodness this invasion came with the slowing motion of Sonata’s hip-thrusts, or Trixie might have just cum herself into a coma. But by Luna’s leaking labia, did that index finger worming into her other hole feel fantastic! Trixie couldn’t grind herself back and forth fast enough now, letting that mare-breaker stuffed up her shaft stretch and sunder her walls while bucking back against Sonata.

“Seat comfortable -umph’ enough, Sonata?” Trixie hissed.

“Uh-huh! Adagio got enough bits -mmf so deep- to spring for the real foam seats and-and-oh, cumm-”

Goodness what was it with this Siren and barely giving warning? Trixie wouldn't be complaining anytime soon though - not after a second helping of sperm rumbled into her womb. Again Trixie's stomach swelled, her spirits lifted to high heaven, and her voice rose to obscene levels. Plus side, Trixie was starting to remember why all those noise complaints had racked up everywhere she and Sonata got frisky.

Swiveling her hips around her liquid treat, Trixie found herself on the verge of another orgasm herself - one that Sonata provided when she yanked her fingers out of Trixie's plothole and slapped her ass. Her cheeks jiggled and she shot herself off Sonata’s cock, only barely missing banging into the roof. Sweet release however, found itself soaking two pairs of shaking blue legs.

Wouldn’t be an issue, if not for the fact Trixie’s feet were balanced on that second set of legs. She found herself flopping back into the passenger seat, Sonata there to keep her comfortable.

Still… “Not funny, Sonata.”

“I didn’t laugh, Trixie! I swear!” Sonata whispered.

Trixie let out an exasperated sigh. “Know what? Nevermind. By Celestia, that was amazing.”

“Are you sure?”

“Positive.” Trixie waited as Sonata slid out from under her, half out of the car again as she waited for her Siren to turn around. “Besides, I’m positive you’ve pushed as much cum into Trixie as - you’ve gotta be fucking kidding.”

Sonata tucked a finger on her lip, unsure of what Trixie was staring dumbfoundedly at. Oh! It could be her cock, still wonderfully rigid and plump at her crotch. “Oh. Yeah….” she sheepishly admitted. “Adagio said this was why I probably shouldn’t be keeping up this sexytiming. Says we’d never get any sleep if I went at it till I was drained.”

“Do… Do you ever tire?”

“Oh yeah! Once, way back when! I had fins and everything, it was awesome! But…” Sonata pouted. ”I don’t think so. Not since I’ve been in this town, no.”

Once again, Trixie’s daring streak flared. Oooh, the first to exhaust the inexhaustible reserves of this dainty dreadnought of a futa? This contest really would be perfect. “Perhaps… Trixie should let you in on a new way to do this."

Sonata took the whispered instruction with widened eyes. “Really? That position? But didn’t you say that cramped like crazy the last time Adagio told you to take that-?”

“Trixie promises you, Sonata.” the showmare whispered as she looped her arms around the crooks of her knees. “I am definitely limber enough now.”

Ironic considering the gutful of spunk, Trixie could take this position. Almost bowing to accommodate the dip in the seat cushions, Trizie wiggled her hips once she was certain the twinkle had faded from Sonata’s starstruck eyes. Her clit, gaping and gooey, beckoned to Sonata’s senses again.

But Sonata, following Trixie’s instructions, didn't dip inside that stuffed slit yet. Instead, she scooped a dollop of fresh seed from Trixie’s thighs and rang it around Trixie's puckered plot. Trixie’s sighs and curses soon filled the sex-thick air, bringing a satisfied hum from the Siren.

Then slowly, Sonata positioned herself just above Trixie, bending herself to avoid hitting the Mako’s ceiling. Unlike that car in front of them, they were not blessed with the space of a sunroof. Still, enough room was ceded that Sonata could find herself looming over her waiting cumslut.

“Not to worry you, Trixie, but… you saw how I was just going in your clit! If I fuck you… here,” Another Sonata-spawned tug at her puckered hole sent Trixie into a blubbering flurry. “I’m not sure I can stop.”

“That’s just the thing, Sonata,” whispered the showmare, letting Sonata grip her ankles and keep her in this mating press. “Trixie is counting on it.”

So in went Sonata Dusk, right into the plot of her special somepony. Despite her two orgasms previous, it was only here that Sonata first started seeing fireworks fill her vision. Trixie was absolutely hot, both figuratively and literally, with her tunnel clamped shut upon her like a vice.

And Trixie’s voice was probably now at raise-the-dead levels.

Sonata’s eyes shot open in concern - not verbal concern, that was for a Siren who wasn’t halfway deep in the ass of a sexy showmare - but Trixie availed her concerns. “No! Keep me like this!” she yelled, grasping at Sonata’s shoulders, sandwiching herself further. “Please! I need it!”

A raspy growl came from the Siren above her, and then Sonata started pushing further. By the time she was rooted crotch-to-rump, she was sweating rivers and almost mute with pleasure.

Sonata started her violent hole-hollowing thrusts anew, and soon Trixie was rocking in the cradle of that seat, her eyes rolling in hapless glory. For once, Trixie was too speechless for words. From the warm bulge at her stomach, to the scorching how musk of sex hanging thick between their inch-close faces, to the volcano building in her insides...all of it combined was enough to have her see double.

Especially with Sonata swallowing every other moan the showmare bellowed with a searing kiss. The blueberry tang of the Siren’s lipstick only served to make everything that much more exotic; not that Trixie could focus on it for long with Sonata's length plowing its way into her with relentless vigor. The erotic grind of their sweat-slicked bodies against one another fueled the continued passion of their lustful embrace, the two of them steadily losing track of where one of them began and the other ended.

With the way her blue-cated paramour’s depths were rippling around her length, though, Sonata knew she wouldn’t last long. Her sex drive at this stage was like the inertia of a speeding freight train - slow to get going, but unstoppably powerful once it got up to full tilt. Sonata could already feel the crescendo of her next immense release building deep within her core, a spine-tingling undercurrent of lust that drove the speed and power of her groaning, hip-swaying thrusts into that Great and Powerful booty. Sweaty smacks of her greedy hands around the finely-honed curves of her mate’s flanks were the punctual stabs in their carnal orchestra, her bass grunts pairing with Trixie’s high squeals in a combination that was music to her ears and her loins.

With a deep groan, Sonata’s eyes rolled up into the back of her head as she bottomed out in Trixie’s ass, a shuddering, toe-curling climax setting her nerves alight as blood roared persistently in her ears.

She could feel the soft, bloated pudge of Trixie’s midsection as it jostled against her own, swelling even further as more and more ropes of thick siren seed blasted their way into the showmare. It was the cherry on top of the sundae of dicking decadence that Trixie had treated her to; a blatant visual testament to the strength of their desire for one another. That, and the scale and intensity and productivity of her monstrous length’s never-ending libido.

Grinding to a halt as the intensity of their shared passions began to catch up to both of them, the two of them shared contented sighs as they nuzzled their faces into one another, the siren still buried hilt-deep in her ass but content to remain there for now.

Or she would’ve been, had Trixie’s eyes not snapped open with panic as a jarring realization broke her out of her latest afterglow.

“Getoutofhereoryou’llstaintheseats!” She spluttered in a panicked babble, hurriedly pushing Sonata off of her as the door to the ‘Vette swung open, depositing the siren onto the soft expanse of grass that (thankfully) laid just outside the passenger door. (It was a good thing, too - that asphalt looked tragically hot for bare skin on a day like today.)

“Trixie, what the hay! Ponies are gonna see us…” Sonata bemoaned, hastily covering her chest with one hand as her other ineffectually tried to coax her crotch monster into compliance. Looking up from her modesty check to glare at the impulsive mare, the rest of her thoughts died mid-formation as she beheld the spectacle before her.

On shaky but still undeniably gorgeous legs, the boisterous mare was positively glowing as she proudly stood up from the passenger seat, casting her lidded gaze across the mostly already distracted patrons of the car wash. As proud and cocksure as her behavior was, it was offset by the sticky, thick trails of seed that positively flooded from her lower holes the moment she stood upright.

“Let them watch! The Grrreat and Powerful Trixie thinks most of them are already quite distracted, anyway…” The mare trailed off as she crouched down to Sonata’s level on the grass, taking a commanding hold of Sonata’s length as she shared a meaningful gaze with her. “The only thing Trixie is focused on is getting you so utterly drained that you’ve no choice but to sttay flaccid. And if that means Trixie has to fuck herself on this monster cock you’ve got until she’s screaming like a harlot in front of everypony here...then all the better.”

That was all the shameless showmare had to say to get Sonata to drop her hands from her front, both her nipples and length alike hardened to a positively monolithic stiffness. Despite the burn of her muscles, Sonata was not too exhausted for a mounting - and so she made no move to protest when Trixie plonked that thick ass of hers down in her lap, wedging her virile length between those tantalizing, wand-adorned blue cheeks as the showmare ground her ass against her. Trixie didn’t waste time with further foreplay, either, as with a lift of her rear end, that already seed-smeared length slid effortlessly into her backdoor, all the way to its very base, without Sonata even needing to assist.

Trixie certainly moaned a litany of praises and profanities regardless, though. That dense blue butt rippled like a waterbed with each heavy crash of Trixie’s rear onto Sonata’s gently bucking hips; the siren propped her upper half on her elbows and up against the side of the Mako, so as not to miss a single second of the enchanting show of wanton lust her marefriend was giving her. Neither the cool grass beneath them, nor the cold embrace of the door at her back, did anything to diminish the enthusiasm Trixie had for being given the time of her life.

Wrapping an arm around Trixie’s upper half, Sonata's hand reached up to greedily palm, pinch, grope, and fondle the showmare’s hefty tits as she used her newfound leverage to pull the mare up into a seated position on her lap. Were it not for their nudity and the obvious motions of their impassioned mating, they might’ve looked like a particularly handsy pair of lesbians taking a break from their washing duties to hug it out.

Not too far from the truth, either.

Regardless, the newly adjusted position allowed Sonata to try something she’d been eager to do, ever since Trixie’s own aggressive behavior a few orgasms earlier. As her tongue greedily lapped at the salty sweat adorning Trixie’s shoulder, she gave her first hesitant nibble into that Great and Powerful collarbone. The showmare reacted immediately, clenching like a vice around her length from the very moment those sharp canines grazed threatening trails into the delicate skin, and that teeth-gritting increase in tightness was all the incentive Sonata needed to go all-out with her ministrations.

The milking intensity of Trixie’s tight ponut reached a fever pitch as Sonata’s teeth grazed inky marks down Trixie's neck. Between Trixie's cries and the feeling of her tunnel clenching Sonata, the siren was powerless to resist the insistent, fluttering ripples that clamped down upon her length when Trixie came hard from the immense stimulation. Sonata had found her blue lover’s weak spot, and damned if she wasn’t going to abuse that power to its fullest extent.

Gripping her mare by the hips, she picked up where Trixie’s orgasm had stopped her bouncing motions - and started jackhammering that hot ass.

Sonata hips were an absolute blur as she pounded her way up into that tight backdoor with absolute abandon, the strengthening tide of her libido adding weight to her thrusts as they halved in pace but doubled in power. An incoherent, half-groaning, half-moaning symphony of exultations were mumbled into Trixie’s shoulder as Sonta's hand tightened its grip on the showmare’s tit enough for it to leave indents in the squishy mound. Her free hand then struck true against that reddened, jostling ass as her final thrust bottomed out completely inside her mare’s deepest reaches.

Her gentle nibbles against Trixie’s shoulder shifted into a full-on bite down into the muscle, nearly enough to break the skin, and prompting Trixie to let loose an ear-splitting shriek of pleasure and pain as a gout of their mixed essences spurted out of her fluttering cunny and ran down onto her plump, clenching balls.

Those plump blue cheeks spread wide around Sonata’s cock as the two of them pressed into each other firmly and greedily, each demanding more depth from the other, though neither of them had any left to give. The messy splurts of Sonata's thick, virile siren seed were nearly audible as they rocketed their way out of her length to join the indulgent mess of futa cum beneath them.

Panting heavily as they slid down from their exultant highs, the two blue mares shared a loving gaze with each other as the sounds of squeaking suspension and muffled moans echoed from within the car in front of them.

“Trixie told you we weren’t the only ones. The way Tempest and Aria...were looking at each other...was insufferably obvious…” Trixie gasped out between laboring breaths, her fingers running through Sonata’s striped mane as the siren’s length twitched fitfully inside her amidst the last trickles of its release.

And then...unbelievably...it softened.

Sonata’s eyes widened as she held her gaze into Trixie’s soft purple orbs, the feeling of her length slipping out of the showmare’s thoroughly-used hole being all the convincing she needed...Trixie was the one. And if being with Trixie meant getting to experiment in all sorts of excitingly lewd ways, like they’d just done?

She’d give anything to keep the two of them together. Especially since she was starting to like the whole “biting” thing.

For now though, seeing the size of another creature’s bit was all that was on the futa’s mind. “Trixie…. She whispered. “Still up for watching the rest of Shark Week? Then we can catch Mega Jaws of Griffin Island if we’re quick.

Trixie grinned, still tracing stars into her bulging belly. “Unless Adagio was cocky enough to leave the keys in this beast….” A swift jingle of something in Sonata's hand answered that inquiry. “Never mind. That’s the most unbelievable thing Trixie has seen today.”

Sonata chuckled. “Aria gave me her pair, actually. She got a peek at me under the hoodies and figured I’d need all the distance I could get when Adagio found out.”

Trixie’s eyes flitted back to the booth. “Then Trixie will let you lead this time. After we finish with the other cars.”

‘Let me lead?’ threatened to slip past Sonata’s lips, but she knew better. So she mingled, and trailed a hand over the belly of the mare that had humbled her fuckpillar, and watched with twinkling as Trixie strutted back to her friends with a spring in her sperm-heavied step.

In short, today was a great end for Sonata’s own personal Shark Week.

“'Kay, Sona, we’re back from- sweet Novo, who did you let on our freakin’ hood?!”

Sonata’s eyes widened at the sight of the freaking-out Adagio. Speaking of seafaring backbiters...
