The Sluttiest Siren at the Party
Chapter Two
-by Drace Domino

“Adagio, look! Hey, watch me do a cartwheel!”

“Adagio, hey! Wanna play that squirrel video game with me again?!”

“Adagiooooo, I got my hand stuck in the sink again!”

“Hi Adagio, want--”

“Will you just shut the fuck up already?!” Adagio finally snapped, spinning on a heel with her hair frizzy and one eye rapidly twitching. She was glaring straight at the girl that had been pestering her endlessly all week long - her little sister Sonata Dusk, the most infuriatingly annoying girl she’d ever met in both Equestria and the human world alike. Sonata was standing just a few feet away in a cute belly tee with her head tilted, one hand holding a single potato chip while the other was extending the open bag towards Adagio.

“...to try these new sweet and spicy chips?” Sonata finally finished her question, though with a significantly larger pout than when she began it. Adagio simply bristled her shoulders as she swung her hand outward, snatching the bag from Sonata’s hand as she spun on her heel. The two girls were at their shared apartment not far away from their new school - a single-bedroom place that was cramped under the best of circumstances. Even more so, when one of the inhabitants was Sonata.

“Fine. Thanks. Whatever,” Adagio grumbled, stuffing her hand into the bag and munching greedily on a few chips. While she walked through the single-file hallway of their apartment to the living room she finally gave another grunt in acknowledgement of her sister’s presence, glancing over her shoulder as she did so. “Can’t you leave me alone for ten fucking minutes?”

“Well gee, excuse me, Adagio.” Sonata continued to pout, chasing along behind her big sister and making a grab to reclaim her bag of chips. After two failed attempts she extended herself forward, pushing her chest to Adagio’s shoulders while she reached around and reclaimed it. “But ever since Aria got on the cheerleading squad, there’s nobody else to spend time with! You won’t let me be friends with any of the other girls in school!”

“That’s because you can’t keep your fucking mouth shut, as evidenced by my blood pressure,” Adagio murmured bitterly in response. “If you make a bunch of friends amongst the humans, the next thing that happens is that they’ll all know everything about us. About Equestria, about Canterlot High...everything.”

“Give me some credit!” Sonata snapped, glaring. “I might not be as smart as you and Aria, but I’m not stupid!” She paused, just long enough to pluck a chip out of her bag and messily crunch it up before swallowing. “I don’t want to run off to somewhere else again! I can keep my mouth shut if it means we don’t have to pack up all our things for a third time! And if you won’t let me have friends, then the least you could do is spend time with me! I’m boooooored!”

Adagio took a deep breath, and lifted a hand to pinch the bridge of her nose while she moved to their sofa. After flopping down into it with a thud, the Dazzling snuck a hand into her pocket, her fingers wrapping around her cell phone as she cautioned a glance towards her little sister. Her eyes were narrow and her expression was sour, and yet...it wasn’t totally cruel, and neither was the girl that offered it. Sonata Dusk was her sister, after all, and she’d been with her and Aria every step of the way through their long and seemingly endless trials. Finally, she gave a soft sigh as she pulled her cell phone free, looking down and flipping through the admittedly limited contacts.

“Fine,” she grumbled. “I’ll arrange a...playdate.”

“Ohh, really?!” Sonata giggled, and bounced beside her sister on the couch so hard that it made Adagio’s curvy frame jiggle, just a bit. She pressed her hands into her lap and loomed over Adagio’s phone, so much so that the elder sister had to actively swing her arms to the side so she could keep her eyes on her contacts. “Who am I gonna hang out with? That girl at school you always pick on? The janitor you made cry last week? Oh! That guy at the coffee shop that always spells my name with a T?!”

“What? No,” Adagio grumbled. “Nobody in this town. Someone from Canterlot High. So that way, even if you fuck up and tell them everything, it won’t really matter. Let’s see here…” She flipped through the contacts with a lazy finger, finally falling on a name. Well...not a name so much as a title. Hot Stupid Boy from the Party. “Here. I’ll set up a date for you both. You meet him, you fuck him, you leave me alone for a solid week. Deal?”

“Fuck him?” Sonata blinked, before rapidly giggling and nodding. “Ohh, I would’ve been happy with someone to play checkers with, but that’s even better! Is he any good?!”

“He’s in my phone, isn’t he?” came the curt response from her older sister, just as Adagio sent the call and held the phone up to her face. She was going to save her Canterlot High booty call for a personal emergency when she just really, really needed a good fuck...but this situation was getting desperate. If foisting her little sister off on the stud from the party would buy her a little bit of peace and quiet, then it was well worth the call.

“Greetings, weak and pathetic human chattel,” Adagio began the conversation in less than stellar fashion. “I demand you drive out to our town so you can use the only redeeming thing about you to silence the incessant prattling of my foolish little sist--” A pause. “He-hello? Hello?”

She looked at her phone, made an irate face, and sighed. This could be more effort than it was worth.

***

It was later that evening that Flash Sentry stepped out of his car and slightly grimaced, looking across the half-filled parking lot of a seedy hotel forty-five minutes out of town. This was the place all right, and he made sure of that fact by flipping out his phone and double checking the address, right down to the room number. The young man rolled his eyes at that point, and stuffed his phone back into his pocket and started to make the slow walk across the lot to the appointed room.

“She could’ve at least sprung for someplace nice,” Flash grumbled, though in all fairness, he didn’t have much reason to complain. He had nothing planned for that evening to begin with, so when Adagio called him out of the blue with a strange but tempting request, it didn’t conflict with anything else the young man had planned. He didn’t know why Adagio wanted him to come and fuck her sister, nor did he particularly care about the reason - from what he remembered, Sonata was pretty cute, and that was more than enough to get him to make the drive. A little strange to be sure, but...he was technically dealing with Equestrian monsters from another dimension, after all. They probably just did things differently over there in magical horse world.

That wasn’t to say he made it easy for Adagio to convince him. Especially since she had trouble remembering his name, Flash made sure that the Siren was going to pay if she really wanted him to help her out. The chosen payment was simple and had already been rendered: a hotel room for them to do the deed, and a few filthy pictures of herself to keep on his phone. The former he probably should’ve been more specific about regarding quality, but the latter? The latter couldn’t have been better. One shot of her in her apartment’s bathroom lifting up her skirt and spreading her pussy, and another bent forward from the waist, her fingers reaching around to show off her exposed, spread asshole. He had to admit...it was a little surprising she went along with it, offering up pictures of herself just so he would come over and fuck her sister, and it was all the more proof that the Dazzling was desperate.

And also very, very slutty. It was good to know for the future.

Flash Sentry didn’t bother to knock on the hotel room door when he arrived, instead simply putting a hand to the knob and opening up, casually inviting himself inside. He was treated to the unmistakable smell of a cheap hotel - sheets that had been washed in the cheapest of detergents and the faint aroma of recycled air from the nearby conditioner, which was humming so loud that any reasonable person would have a hard time sleeping near it. Fortunately, this wasn’t the sort of place where most of the guests did much sleeping. There was a single bed in the center of the room and a TV straight across from it with a music video blaring at full volume - PostCrush, to be exact. Sunset’s favorite. The only thing he didn’t see in the hotel room immediately was Sonata Dusk, even after peeking around the corner to see the restroom door hanging open.

“Sonata? You in here?” the young man called out, his brow briefly furrowing as he did so. There was still the chance that this was all some Dazzling trap, but he’d already made preparations just in case. One of his buddies from the football team knew where he was going that night, waiting for him to text that everything was on the level. You couldn’t be too careful when driving out of town to fuck an evil other-dimensional demon girl’s little sister! “Helloooo? Sonata?”

After giving the room one last scan he finally gave a tiny shrug, and flopped down on the edge of the bed while he fished his phone again from his pocket. While he waited, he casually flipped to the pictures of Adagio Dazzle once more - whether it was an exposed pussy or a spread asshole, the look of obscene, shameful, smug pleasure on the bitch’s face was perfect in both. She really was a trashy bitch without any question, and as Flash sat there studying the images he naturally felt himself start to stiffen. Teenage hormones had been flaring the entire drive over, and now that he was there waiting for the arrival of his pussy delivery, things were starting to rush through him with even more ferocity. He squirmed, and idly pressed a hand against the center of his jeans to adjust his stiffening cock within his boxers. Hopefully, Sonata showed up soon, and he could get this night underway.

He didn’t have to wait long, as luck would have it. Just a few minutes after he sat the door started to open again, and the girl of the hour made her way inside while humming sweetly to herself. She was wearing nothing more than the robe provided by the hotel, carrying a bucket with ice and a few cans of soda in one hand, and a pack of red licorice in the other. One of those sweet cords was dangling from her mouth as she slipped inside, and a big smile spread around it as soon as she saw that the boy she was waiting for had let himself inside.

“Hey! It’s you! You’re really here!” Sonata grinned, talking around her candy. Before long she had the soda and snacks placed on the nearby table, and plucked the piece of licorice out of her mouth to balance it precariously at the very edge of the counter. Her hands braced against her hips and she stood there with a bright smile on her face, her slender body completely obscured by the thick and scratchy wool robe but nonetheless framed in an appealing fashion. She was nowhere near as curvy as her older sister, but what she lacked in a chubby ass and curvy breasts, she more than made up for with a sleek frame and a much more likeable personality. “Wow, I didn’t really think you’d show up! I was planning on just charging Adagio’s card with pay per view movies!”

“Well, we can do that, too.” Flash Sentry stood up to greet her, in true gentlemanly fashion. His smile was pleasant and friendly - even though Sonata was technically one of the wicked sisters, it was always hard to look at her in the same way as Adagio and Aria. An evening hanging with her, fucking and watching a few flicks might actually be pleasant. “Maybe we can watch something after we’re done?”

“No thanks, I really just wanna fuck!” Sonata giggled, and dropped her hands to the belt of her robe, starting to pull it away. “Just because I’m horny, that doesn’t mean I wanna waste my time hanging out with ahuman. Ick! Gross!”

Flash just rolled his eyes, and let his hands drop against the rim of his jeans.

“Right. Forgot. You’re still kind of a bitch.” He sighed, and rolled his wrist in impatient fashion, tapping a foot. “Well? On your knees, I guess. Let’s get a dick in your mouth.”

The Dazzlings might have been depraved sluts that were ready to get fucked at the drop of a hat by a well-hung stud, but...they sure as hell weren’t girlfriend material.

***

The bathrobe hit the floor just a few seconds before Sonata Dusk’s knees, revealing to Flash Sentry just what a cute figure she had. Small-chested compared to her big sister, the girl’s light blue body was nonetheless endearingly sculpted, with a smooth belly and tight backside that any horny teenage man would be eager to get his hands on. She was wearing her hair in her typical ponytail that night, and Flash didn’t hesitate to wrap his fingers around its base the second she first hit the floor. Even before he took out his dick, Flash yanked Sonata forward and forced the Dazzling’s face against the bulge of his jeans, looking down to see Sonata’s nose lost against the denim as she gazed right back with a look of impure lust riding her face.

“So, are you as big a slut as Adagio?” Flash mused aloud, brow lifted and his cock grinding back against Sonata’s face through the fabric of his jeans. He was a nice guy back before he realized just how the Dazzlings needed to be treated - if Adagio was any indication, the Equestrian-born sluts only responded to a very particular type of treatment. “Because when I fucked her, she was moaning so loud the whole damn party knew. Do I have to worry about people banging on the door telling us to keep it down?”

“Mmm...that depends on how good you are at using this,” Sonata cooed in honest response, greedily nuzzling back against his crotch, one of her hands slowly lifting forward. She moved her fingers to the clasp of his belt and started to casually toy with it, just as her tongue slithered out to tease at his zipper. Once she had it balanced on the tip, she was able to stretch her mouth forward just enough to pinch the metal tab between her teeth, and slowly she began the process of pulling it steadily downward. She only stopped halfway through to release his zipper again, and with her nose nuzzling in the now-open spot against the fabric of his bulged boxers, she spoke with a playfully naughty voice. “Adagio’s always going out and having fun with guys, but mostly I just play with Aria. So you’re really gonna have to work to show me you’re worthwhile, human…”

Flash just arched a brow, and in the same fluid motion the corner of his lips lifted into a tiny smirk. His fingers slowly and steadily tightened around the base of Sonata’s ponytail as he surged forward with his hips, giving Sonata’s face another slow grind while she once more claimed his zipper with her teeth. She worked slowly and teasingly, clearly enjoying the filthy display as her free hand continued teasing his belt upon and her head dipped down to the base of his zipper. Soon there was a soft leather flapping noise as his belt came undone and his pants loosened, and it wasn’t long after that Sonata hooked her fingers into his pockets and started to slowly, purposefully, pull them down.

Flash allowed himself a satisfied sigh as they dropped, his boxer-clad crotch once more grinding against Sonata’s face. With the denim pulled away it was all the more thrilling, and his significant erection could fully feel the pressure of her cheek against his length. His boxers were noticeably stiff at the front with what was clearly an inspiring member, and even though Sonata tried to play it off as if she wasn’t impressed...he could still tell. The nibble at her bottom lip. The briefly flared nostrils and wide eyes. The fact that she very nearly reached her free hand down to tease her own smooth pussy before wisely thinking otherwise.

“You’re...adequate, for a human,” she mused, to which Flash could only give a chuckle.

“You sound just like your bitch sister,” he offered, before letting his hand move to the flap of his boxers. He nudged her cheek away with the back of his hand, just before pulling aside the flap and coaxing his dick out to be exposed. “Let’s see if you suck cock as good as she does, too.”

From there, he was left revealed. Sticking out from the front of his boxers was Flash Sentry’s genuinely impressive cock - thick and long, a rod that made the boys in the locker room jealous and had practically broken Adagio Dazzle a week and a half ago. It flopped outward and draped straight across Sonata Dusk’s forehead, her nose nearly smacking against his balls, which were half-hidden by his boxers. He sighed once he pulled himself free, casually allowing the weight of his prick to rest atop her head, giving her the chance to come to terms with what he knew was a quality cock. Something that, before Adagio had turned into his personal whore for the evening of the party, he had been somewhat modest about. Such humility didn’t serve a human well when dealing with the Sirens, though. They responded to magic, to power, and to the authority of a thick cock that demanded their attention.

And clearly, Sonata Dusk was every bit the slut her sister was.

“It’s...wow,” she finally managed to squeak out, her hands resting on Flash’s thighs as she tried again to play off her impressed state. This time, she failed miserably, partly due to the fact that she couldn’t stop from sticking her tongue out to give his balls a tiny, swift lick. With a voice of awe in her throat, Sonata finally managed to wrap her fingers around the base of Flash’s rod, slipping her head out from below it to stare up at him with narrow, judgemental eyes. “Did you always have this thing? Because I remember seeing you at Canterlot High, and maybe if you showed this off at the Battle of the Bands instead of your substandard guitar skills, maybe you would have made the final cu-mmphhh…!”

Flash Sentry just rolled his eyes, tightened his hand around the back of Sonata’s ponytail, and introduced the sweetest of the bitchy Sirens to his big human cock straight into her mouth. He wasn’t cruel about it - at least not yet - with his tip coming just shy of driving into her throat, and half of his cock still grasped merely by Sonata’s hand. Still, he worked himself past her lips and forced her tongue flat against the floor of her mouth, making sure that she couldn’t continue to berate his musical chops without denying herself a flavor he was sure she’d enjoy. Sure enough, as soon as his rod balanced atop her tongue, Sonata’s eyes opened and she wiggled her backside in excitement, her fingers squeezing a little harder at the outside of Flash’s thighs. Completely robbed of any pretense that she wasn’t impressed, Sonata gazed up at the human with a blush on her cheeks and a smile creeping at the corners of her mouth - the latter intensifying as Flash slowly pushed another smooth, thick inch inside.

She was damn cute with her mouth half-stuffed with cock, her eyes shining with excitement, and her tight blue ass wiggling from side to side. Just like her big sister Adagio Dazzle, Sonata Dusk was a girl best dealt with when she had a dick to keep her quiet. Just another out of town slut to use and enjoy - not like the good, sweet, decent girls back at Canterlot High.

Sonata’s tongue started to roll back and forth as she savored the taste of Flash’s cock, trailing it around the head a few times before trying to slurp deeper down the shaft. Flash made it easier for her by stuffing himself a little deeper inside, always threatening to come closer and closer to jamming his girth straight down her throat. She seemed responsive to the idea, without recoiling or pulling back even as she neared the hilt, and when Flash could finally feel his tip moving past her mouth and into her gullet, Sonata didn’t flinch. For a girl that supposedly didn’t play with the guys in school as much as her big sister did, she was handling him well - and she was sporting a greedy, hungry look in her eyes.

Flash rewarded her for hilting him by slowly pulling back, his fingers pinching at his base while his cock left her gasping lips. While she held her mouth open and trailed her tongue out in an attempt to reclaim it, the young man casually swung his member back and forth, giving Sonata a few light slaps with his meat, smearing her spit and further showing just how cock hungry Sonata was. Her head continued to turn from side to side in an attempt to reclaim it, and she soon gave a pathetic whimper while her hands swept from Flash’s sides to his length, pinning it straight forward and finally wrapping her mouth around it again. As she started to bob up and down, faster this time, Flash gave a broad smile and further tightened his hand against her ponytail.

“Hungry slut,” he mused, and didn’t offer any more explanation for what he did next. His hips pulled back only to pump forward once more, and in the same moment he jammed Sonata’s head down against his lap with even greater strength. Her eyes opened wide as her throat briefly bulged, and the Dazzling barely had a chance to recover before he did it again...and again...and again. With a few vigorous thrusts of his hips he found himself steadily facefucking the Siren - not brutally so, but enough to make sure that she knew the pecking order within their hotel room. After a few pumps of his hips to the point that Sonata was drooling long lines of spit from the corners of her lips, Flash pulled himself out once more, giving her another series of cockslaps that left her far messier than before. The entire time Sonata gazed up at him with half-lidded eyes, her cheeks carrying a heavy blush and a few desperate, begging whimpers escaping from her throat.

“It...it’s so tasty…” she murmured, already showing herself to be a far more humble lover than Adagio. Once that outer layer of Siren bitchiness was facefucked through, there was an eager, wanton tramp underneath. She teased her tongue forward to slurp at his balls while she gratefully received the slapping of his cock, whether it was over her cheeks or against her forehead, shuddering in lewd delight as she was debased. “Please give me...give me more…”

Flash just grinned, his confidence rolling through him just as ferociously as it had with Adagio a week and a half ago. The desperation of a horny Siren was enough to make a modest teenage boy feel like a king, especially with their spit clinging to his shaft and their naked, trembling body exposed before him. Flash soon moved to the edge of the bed and crashed down against it, sitting with his jeans still around his ankles and his T-shirt still snugly gripping his fit figure, cock jutting forward in a further demand for attention. Sure enough, Sonata was upon him immediately, fawning over his cock within the limits of her ponytail leash. She pawed at the sides of his shaft while her face buried itself against the spot where his balls and cock met, slurping, suckling, kissing, making a spit-soaked mess of the whole thing. And when Flash wanted a more snug grip around his member he simply yanked against Sonata’s ponytail to pull her face forward, and once he had that warm, wet mouth on target forced her head straight down against his rod once more.

Sonata gave a squeak as her throat was fully fucked in that moment, her nose buried in Flash’s lap as he tented the fingers of both hands against the back of her head. Her little hands gripped fiercely at his thighs, digging her nails into his flesh as she unleashed a muted and muffled groan, spit escaping the corners of her mouth riding along desperate, choking bursts of air and her eyes rolling back in her head. The noise she made was one of depraved, sloppy delight - a moist whimper that echoed deep inside of her while her slender, naked body shuddered greedily back and forth. The entire time her tongue remained in constant motion, flickering back and forth underneath his shaft, reaching the spot where his balls began, and absolutely worshipping every inch of him that it could reach.

Flash Sentry braced himself, and with both hands working his fingers into Sonata’s hair, started to truly control the pace. He pulled her back and forced her down anew in a series of short and repeated strikes, each one making Sonata give a whimpering squeak as she was forced to deepthroat him. His motions remained shy of cruel - rough, to be certain, but not heartlessly so. He didn’t have any desire to see Sonata cry or for the Dazzling to have a bad time sucking him down, but it was clear she was enjoying being treated like a free use slut...and that was exactly what he did. Up and down he forced Sonata’s mouth around his member, staying acutely aware of just how hard she was gripping his thighs and paying close attention to her noises. When he gazed down to see her face he was met with blushing cheeks and the whites of her eyes as the rest was rolled back, the little blue slut in a near-euphoric state as she was facefucked. Before long, Flash could feel his first climax of the night starting to build through him, and he had to make a quick decision about just where he wanted to unload his peak.

Straight down into her throat, with his cock to the base? It seemed a little cruel to his still-inexperienced self. Why, she could choke like that! Right into her open mouth with his cock at the edge of her lips? That felt like leaving her off the hook, giving her a warm treat without really driving home how slutty she was. Finally, Flash found the perfect middle ground as his member started to throb and he felt his climax begin. With one swift shove he sent Sonata Dusk away from his cock, pushing her so the girl was leaning straight back. She rested on her knees with threads of spit dangling from her mouth to her tiny chest below, and it was that set of modest tits that Flash aimed for with a hand around the base of his cock to pump it the last few strokes needed.

“Ahhh…!” Sonata gasped as Flash’s cum started to spray forward, striking her chest in hot, white streaks that left her entirely by surprise. The first shot was an enormous load that ran from the edge of her throat all the way down to near her belly button, and the third, fourth, and fifth plastered right against her tits. The curve of each breast was left dangling with spunk and he managed to strike both stiffened blue nipples with a streak, leaving the sweet Siren wearing his cum in stylish fashion by the time he was completely done. When he finally finished, Sonata Dusk was left breathing heavy - chest rising and falling underneath the streaks, nibbling her bottom lip as she braced herself there in the aftermath. Finally she spoke, looking up at Flash and his still-hard member, her voice almost accusatory. “You...you wasted it! Just over my boobs?!”

“I didn’t waste anything.” Flash smirked, leaning back on his hands with casual, smug confidence.

“Sure you did!” Sonata persisted, pouting. “You...you could have made me swallow it all! Or just held back and pumped my pussy full of it! Or--oh hey, this thing’s still going!” She blinked, and reached out a hand to wrap it around his member, still sensitive but stiff. “Wow, you’re all ready to go again, aren’t ya?”

Flash simply nodded, and slowly started to rise from the edge of the bed. He let a hand drift down to claim Sonata’s ponytail once more, treating it like the leash it was as he began a slow, lazy walk across the hotel room floor. Sonata had no other option but to follow along until she was pulled slowly upward, dragged up to her feet to stand just before the sink and the large mirror that was built against the back corner of the room.

“I didn’t waste my first load,” Flash reiterated, standing behind Sonata while they both looked at each other in the mirror. Her chest was coated, her face was smeared, and she looked like a depraved little slut...even more so when Flash suddenly pushed his hands onto her shoulders and made her bend from the waist. “I want you to see what whores you Dazzlings are while I fuck you.”

Sunset Shimmer, Flash was sure, would be proud of him. He’d really figured out how to wrangle these bitches.

Sonata Dusk barely had a chance to study herself before Flash was on the move again, pressing forward and squeezing his spit-covered cocktip against her already soaked slit. The Dazzling had gotten herself rather worked up while deepthroating her new human friend, and by the time his head popped inside she gave a sudden yelp of delight just as her hands reached forward, bracing against the sink. From there, she was drawn face-to-face with her reflection and was forced to truly take it all in - from the cum clinging to her tiny tits to the spit on her cheeks, to the fact that she could see her own hips moving back and forth despite not consciously willing them to do so. And just behind her, looming with a dominant aura and a fist still clinging to her ponytail, the human stud was smiling as he pushed steadily forward to keep spreading her pussy with his girth.

“Hnnnng…!” Sonata hissed from the back of her throat as she was steadily stuffed with dick, that tight blue opening squeezing him firmly and her shoulders rolling while she handled his size. He was larger than any boys she’d enjoyed at their new school, limited as that selection was, and even bigger than Aria’s toys. It was enough to make her shiver in impending delight, as was the sight of herself in such a disgraceful state in the mirror. When she finally managed to speak again her voice rumbled out with no small amount of excitement, looking over her shoulder as much as Flash’s grasp on her hair would allow. “Did...did you make Adagio look this slutty?”

“I didn’t even have to try,” Flash responded with a smirk, just before jabbing his hips forward to lunge the rest of his member inside. His lap crashed against Sonata’s backside and every inch of his cock found its way inside of her, clapping down to the base so he could enjoy her pussy all the way down. She remained every bit as delightfully responsive as before, her nethers locking against his shaft and giving him a long, slow milking squeeze, her backside pressing against him to try and usher him a little deeper. Before long Flash released Sonata’s ponytail so that he could hold onto her shoulders with both hands - fiercely gripping and keeping her steady as he braced himself for more. “Hold on, Sonata. We have to make sure you have a fun story to tell Adagio, don’t we?”

He was going to fuck this chipper Siren hard - hard enough that he could expect a jealous phone call from her big sister once Sonata had a chance to boast about how much fun she had.

It wasn’t long after that Flash started pumping his hips that Sonata truly realized just what she was in store for - and she practically melted as soon as she did. Her eyes went crossed as her mouth opened to unleash a long and horny moan, her thighs spreading while her feet stretched apart, hoping to usher Flash all the deeper inside of her. With the young man’s hands keeping an iron grip on her shoulders she couldn’t have peeled away even if she wanted to, and as such she had no other recourse but to look in the dirty hotel mirror and witness herself getting used like a cocksleeve by a human. Of all creatures! The more she was pumped the more threads of cum dangled from her breasts and throat, the leftovers of Flash’s recent climax that were now at a danger of falling to the floor below. She was quick to save what she could, lifting a hand up from the sink so she could slide her fingers across her chest, coating them with his leftover spunk before popping them straight into her mouth. While her tongue wiggled in between her sticky digits and she drew down the taste of human seed, Sonata watched Flash’s smug expression in the mirror. They both knew just how lost she was to the pleasure at that point, just how far gone a once-proud Siren could fall when she was subjected to a good, hard, fucking.

And it was good and hard in spades. Flash’s youthful energy and fit physique enabled him to ram against Sonata with consistent pressure, and the inviting, wet grip of her cunt gave him every encouragement to keep pounding without letting up. From time to time he’d let one of his hands shift around her body - holding her by the ponytail for a few seconds instead of the shoulder, or leaving so he could deliver a firm, commanding spank to her perky blue ass. Every time he did, Sonata tightened against his cock and unleashed a tiny yelp of delight, her eyes rolling back in her head as she continued suckling at her fingers. He was fully in control at that point, his rod in glorious demand, and he knew that he could do just about anything he desired with Sonata Dusk in that moment. With that thought firmly in mind, Flash allowed himself a smile as he gazed down - glancing at her tight blue ass and the little, dark pucker that practically teased him. His smile only grew, and after giving Sonata one more thrust down to the hilt, he pressed his chest to the Siren’s back and whispered against the back of her ear.

“Look at how slutty you’re being,” Flash cooed, fully leaning into his more dominant persona, looming above the girl with a grin. Their faces were nearly side-by-side as they both looked in the nearby mirror, and Flash stretched a hand up to hold Sonata’s chin, making sure she couldn’t look away. “And I think I know just the thing for dirty Equestrian girls like you.”

With his free hand, Flash took the base of his rod and slowly dragged it out of Sonata’s pussy. It was a slow and tense moment, with her nethers squeezing and her hips grinding back against his lap, but before too long he pulled free with a wet, messy noise just before aligning himself anew. Pressing against another hole, one much tighter and delicate, Flash finally alerted Sonata to his plan - and the Siren gasped in realization.

“W-What?! In my...in my butt?!” she yelped, her hands locking against the edge of the sink, her body convulsing in a mixture of nervousness and genuine, lewd excitement. Her chest was rising and falling with a gasping pace as Flash started to push slowly inside, and once his cocktip managed to stretch the tight pucker of Sonata’s ass the girl could merely whine pathetically from the very back of her throat. “Ohhhh nnnnnn….s-so...tiiiiiiiight!”

Flash was inclined to agree. As expected considering her slender frame, Sonata’s ass was a gloriously snug fit, and he had only pushed in the tip of his spit and nectar-covered cock. Just below the point of impact Sonata’s pussy was left unattended but not dormant - her folds glistening with excess juice and the entrance itself gaping, quivering, as if she was trying to claim a cock that had left for other pastures. As Flash worked himself inside Sonata’s ass by another inch, and then another, the blue-skinned Siren braced herself with her teeth biting against her bottom lip and her head bucking forward while she groaned, doing her best to keep herself relaxed despite the strain of her freshly-stretched backdoor.

“H...human...you’re so...so greedy…” Sonata whimpered, blushing fiercely as she was slowly, tentatively assfucked. Another inch inside, and she could truly start to get an idea of the impact he’d have on her - her thighs were stretching all the wider now, and her heart was racing like it hadn’t since the thrill of the Battle of the Bands. “You just...just invite yourself to take...anything you want!”

“That’s hilarious, coming from one of the Dazzlings,” Flash mused, still looming close to Sonata with his chest to her back and his mouth at the edge of her ear. In that moment, he couldn’t help but channel a bit of the righteous anger of the students of Canterlot High - of Sunset Shimmer and all her friends, of all his friends that suffered under the Dazzlings’ rule, of Principals Celestia and Luna that had been taken advantage of. His voice was level and firm as he suddenly thrust forward with the last few inches, clapping his hips to Sonata’s ass and threading her backdoor with his cock. “This is for CHS. Tell your sisters.”

Judging by her response, that was exactly what she’d do, albeit in a way that described it as a ride that they would most certainly want to take. Sonata’s voice only rose in pleasure as her asshole was claimed by Flash’s length, stretched taut around the member that was finally pumping back and forth within her tightest embrace. Every time that Flash pushed himself flat against her backside Sonata’s thighs quivered a little more, with tangible lines of nectar hanging from her pussy, swaying back and forth as she was pounded. Her moans started low and hungry before rising into a heavier pitch and she actively tightened herself around his rod to make it all the rougher, shuddering when he was forced to push back against her, grinding against her walls. Before long the slutty Siren could no longer keep her hands braced on the countertop and her shoulders fell to meet it, her head a mere few inches above the sink as she started to whimper in celebratory joy. She stood on her toes when she had the strength to do so in order to meet Flash’s thrusts all the more readily, but it was clear by the wobbling in her knees and the rolling of her eyes that she was starting to falter. If he kept pounding her ass like this she wouldn’t be able to stay standing for long, even leaning against the sink for support.

Flash just kept going. His hands looped underneath Sonata’s belly to give her a bit of support, and the greedy Siren took a mile by suddenly letting her feet completely lift off of the ground. Her knees bent and her feet hitched against Flash’s waist, forcing the young man to do not only the heavy lifting of fucking her, but of keeping her level while he did so. It only fueled his hunger further - giving him a justification for slamming ahead as hard as he could and claiming her ass straight down to the core. If she was going to be lazy about it, then she was going to get fucked to his liking!

With sweat lining his brow and keeping his T-shirt pinned against his chest, Flash gritted his teeth as he pushed himself. This was rougher than even the strictest of Coach’s football drills, and more demanding even than fucking Adagio a week and a half ago. Fucking the Sirens was proving to be the sort of exercise that was well-suited to a young stud, and just like before Flash was absolutely determined to rise to the challenge. The more he felt his muscles strain by holding Sonata up between himself and the sink the harder he treated himself to claim her, gazing down to see that tight blue ring desperately stretched around his shaft, her backside still sporting his handprint from some of the rougher spanks. This particular Dazzling might be the nicest of them all, which only made him wonder - just how far could he push the limits with the others?

By the time Flash Sentry found his climax surging through him, Sonata Dusk had met hers seconds ago and was in the process of alerting the entire damn motel. Her screams of wild delight were echoing in their tiny room so loudly and vibrantly that it was a foregone conclusion that the rooms next to them could hear - not to mention the parking lot, the lobby, and probably the fast food joint next door. Her wordless screams and moans soon managed to break free of the nonsensical babbling, and by the time Flash was grunting in his growing climax Sonata was gazing over her shoulder, eyes wide and smile manic as she called out for him.

“Yes, yes, cum in my ass, human!” she howled, sharing that same astonishing level of disregard for their true nature in such a public forum. There was already an angry pounding on the front door as well as muted calls for them to keep it down, to which Sonata simply cackled like the villain she was. “Never! I’ll never keep it down until he pumps every drop of his disgusting human cream into my aaaaaassssss!”

Flash was left more than a little overwhelmed, but only in the best ways imaginable. His cock held in the fierce grip of a smoking hot teen girl’s ass, his body firing on all cylinders and riding high on adrenaline and desire, his dominant side on full display as he pumped the last few strokes needed to peak. There was no nice guy within him in that moment - no part of him was worried about the people they were bothering in the rooms beside them, nor was he concerned that Sonata’s ass couldn’t take much more pounding. He was a creature of human dominance in that moment just like he’d been with Adagio, and with that last strike his balls clapped against Sonata’s pussy just as his tip plunged deep within her. From there he took a deep breath and swiftly started to shudder, his climax surging through him with reckless joy while the cum started to flow.

It was gloriously intense, so much so that goosebumps ran across Flash’s arms as his head rolled back to unleash a hungry moan all his own. The grip of Sonata’s tight backdoor continued to spasm and flex around his rod as he started to squirt, shooting burst after burst of hot, white cum straight into her most tender hole. He could feel the surging warmth rush across his rod and by the time he gazed back down Sonata’s tiny ass was twitching - her body clearly going through its own trials as his cream squeezed out from between the seam of her tight little ring and his enormous length. Before Flash finally pulled out he shook his hips from side to side, forcing Sonata’s feet back to the floor as he swiftly yanked his hips free. In the brief seconds before Sonata crumpled down to her knees in an exhausted mess, he could see her ass gape from the force that just left it - just before tightening once more in a subconscious attempt to keep her brand new creampie secure.

The two were left gasping in the aftermath, Sonata braced on her hands and knees, her ponytail hanging low and her ass drooling a steady white patch against the carpet below. Flash Sentry was faring better, and after collecting his thoughts he walked over to the table by the door. Helping himself to one of the sodas sitting in a bucket of rapidly-melting ice, he cracked it open while he walked straight back to Sonata, his cock still cum-coated and bobbing from his pelvis.

Wordlessly, he treated himself - with one hand bringing a long draught of soda to his mouth, and with the other moving down to wrap his fingers around Sonata’s ponytail yet again. By that point, he was good at using it as her leash, and it wasn’t hard to force her head upward and bring her mouth straight into contact with the dick he had just plucked from her ass. And Sonata - responding not only to the human’s desires but the sheer level of authority he was able to convey that night - opened her mouth greedily and stretched out her tongue, balancing his tip upon it before slowly sucking in the entire head.

“Ahh…” Flash sighed contently after swallowing down a mouthful of soda, and braced the can at the edge of the sink’s countertop before leaning back on a heel and smiling. He gazed down to where Sonata was still dutifully taking him down, sweeping her tongue back and forth and cleaning his member of the excess cum, working without a single word of complaint. Before long she settled herself on her knees and brought her hands to hold his hips again, moving down the inches until her nose nestled at the base of his lap. The entire time, her tight back pucker continued to squeeze out the creampie she’d been given, just as her pussy was left raw and shivering and squeezed between two thighs that were gently grinding together. Flash finally arched an eyebrow as she watched Sonata work with such devotion, and casually glanced at his watch before rolling his shoulders in a simple shrug. “Already pretty late, and I’m not even half done. Guess I’m spending the night here after all. Wanna order a pizza?”

Sonata blinked, popped her mouth off of Flash’s cock, and pointed to the bathrobe she had discarded that was still laying on the floor. Her smile was wide by then, rocking back and forth on her knees in delight. Any of the disdain she had felt for the human had been seemingly wiped away, completely cast aside once she learned that he knew how to fuck.

“Adagio’s card is in my robe!” She grinned, and licked her lips in anticipation. “Order whatever you want, but make sure to get plenty for both of us!”

Not long after, Flash Sentry was laying back on the bed and placing an order at the most expensive pizza place in town - happily taking a chunk of Adagio’s bank account in the process, all while her little sister sucked his cock and worshipped his balls the entire time.

The Dazzlings were one of the greatest threats Canterlot High had ever faced, but if he’d known just how weak they were when confronted with stiff teen stud dick, Sunset Shimmer never would’ve needed to get involved. For now, Flash laid back happy and content with Sonata’s mouth working along his member, pleased in the knowledge that he had himself a Dazzling harem in the making.

End of Chapter Two.
