Invasion of Privacy

Another quiet day in the Dazzling apartment. Though Adagio wasn't around, she was off doing her usual things. It was only Aria and Sonata had were left around the house. It was fairly quiet and despite Sonata calling for Aria, multiple times. There was no answer. So the blue haired siren decided to take this as an opportunity to go snooping in her big sisters room.

For once, Aria hadn't locked it and this was a golden opportunity to sneak around. How did Sonata know the room wasn't locked? Well, she merely tried the door handle. As she was already inside, the girl shuffled through Aria's things with a big grin upon her expression.

Sonata was wearing nothing more than a pair of denim hot-pants, and a tight fitting white t-shirt. It clung nicely to her body, showing off those large breasts and that slim, firm figure. Squatting down, she was leaning into one of Aria's larger boxes, fumbling through her things; finding all sorts of interesting things. Truly, the girl was bored.

"Wow, I didn't know Aria had stuff like this..."

It was hard not to know what Aria had, but then again, maybe it was? She's not that much of an open book on a lot of things. Weapons and guns, sure, they can expect that, but lately with trips to those shady dealers, with her questionable friends, she had been coming back with a lot of different things.

Though some she kept hidden because she knew her sister would be way to into some of it. Books, magazines, relics, things of the occult and the like. However there was some tickets and passes to a place that, if one didn't know better, would be a sort of strip club or whore house. VIP? She got the deal on that one it seems. Aria was still no where to be found, but there would be that looming sense of danger approaching if Sonata wasn't careful.

Sonata hummed lightly, as she continued to look through her sisters belongings. All these things, very interesting. Some of it was typical of her sister however. The longer they spent in the human world, the more bad traits they picked up and in her sisters case it was mostly items of physical violence. The younger sibling remained squatted before the box, holding up a pistol and rotating it within her palm, it looked empty and she'd aim it toward a poster on the wall.

"Bang! You're dead, looooooser!" Sonata giggled and pulled the trigger, and as she did. The weapon would discharge, creating a hole upon the head of the person in the poster. A loud gunshot echoed throughout the apartment and she'd stumble back on her ass.

"S-S-Shit!" Looking around and seeing no-one, and hearing nothing... she paused. "Fuck... thank the gods that Aria wasn't here to hear that." The girl quickly sat up from her butt, placing the gun back into the chest.

Sonata would soon feel something behind her. No one would have any idea as to how, but looming behind the younger siren was indeed, a woman whom even death tend to have nightmares about. Before Sonata could turn around or anything, she was yanked up to her feet by the back of her shirt, snorting a bit as she shook her head.

"Just what do you think you are doing, you fucking idiot?" She asked, though partially dressed and still a bit wet. Her chest covered by the opened button shirt she was wearing, and also wearing boxers at the moment as well, "What did I tell you about picking up things that you don't know about?"

With a releasing yelp, Sonata found herself being yanked up by her shirt and it was then that she'd stare into the face of her intimidating big sister. "A-Aria?! Oh... oh fuck! I'm so sorry... I didn't think it was loaded, I uh... I just... fucking... uh... came in to have a look around, as you never let me in your room!" She'd then laugh nervously and back up slightly, hands raised against her own chest.

"F-For realsies... I'm sorry! I'll just go, okay?!" It was with those words, that Sonata actually did try and walk past her sister with hopes that she wouldn't be punished.

Aria still had a firm grasp on that shirt, so there was no going anywhere. She glanced to the wall for a moment, raising a brow before tugging and, practically throwing Sonata onto her bed. She picked up the gun that was used, looking it over for a moment the, pressed a button on the side. There was no clip, she should have figured.

"Hm... this isn't a typical handgun, and you using it is... surprising, actually. It's been magically enhanced, don't ask me how or where dork. It doesn't need actual ammunition, but sort of... think of it as using your own magical essence as ammunition. Which shows me, that you aren't as fucked up as I thought, when we lost our abilities the first time around."

The younger sister stared at Aria, watching as she fidgeted with the weapon. Snuggling into the bed, she'd lean against the headboard of her sisters bed and stay quiet for the moment, listening to all that her sibling had to say. Once she was finished, Sonata thought things over.

"Oh. I guess everything is still okay then. We have a chance, right? That's good." With a relieving sigh, Sonata relaxed and enjoyed the comfort of her big sisters bedding, once again, it was something she had never had the chance to sample and now she was just revealing in it. Until her sister would throw her out anyway.

Aria hums a little as she thought things over for a moment, wasn't that the reason she got this relic, for her sister? Well, it turned out to work that way, as she nodded and glanced over to Sonata who was more getting off on her bed than probably focusing. She sighs heavily at that before kneeling down to put the gun away, closing the box up and picking up said box, moving to set it on the night stand.

"Well, it was suppose to be for you as well. So, it might help you out, just, don't go over board with it, as there is draw backs to it." She nods her head, then glances to her sister, raising a brow, "...You're soaking wet right now, aren't you?"

Sonata rolled over onto her front, face buried into her sisters pillow and taking a moment to deeply inhale her sisters natural scent. This was the prime opportunity to do such things, while her sister wasn't kicking her ass. Well, at least now right this moment. Kicking her feet playfully, she'd giggle and stop when Aria was addressing her at the end.

"Huh? You got me the gun? Wow, okay... I uh... I guess I'll use it. But I'm gonna ask you for help okay?" The girl grinned, really she had no clue about such things. Yet when the question was popped, she'd show a stupid grin and roll her eyes playfully.

"Maaaaaybe... I mean, I'm in your room after all. I'm like... never allowed in here, for realsies. It blows!"

Aria sighs heavily as she shook her head some, "Usually you do, but that's beside the point..." she rolls a shoulder some before putting a hand upon her own waist, standing there by the bed, still, open button down shirt and boxers. She glances to her door for a brief moment, sniffing a few times and humming a little in thought some more.

Slowly, she returned her gaze back to her sister, watching her for a moment, she clicks her tongue once, "Speaking of which... want too?" She motions to her crotch for a moment, that signature brow raise seen there.

The blue ponytail girl watching Aria, observing and when she saw that motion toward her groin, she'd sneer with such a cheeky smile. "Oh, yeah... I want too." Sonata commented. "How do you want me, huh, sis?" The girl asked and ran her tongue over her lips as she'd immediately sit up on the bed, legs spreading slightly as she sat there and tried to act all cute, sexy and desirable.

Aria took a breath in then exhales a bit, that was the question, wasn't it. She glances down for a moment, nothing just yet, but that desire was starting to swell up slowly. Another breath in and out, she climbed onto the bed to sit there before Sonata. She then pulled her sister up onto her knees to just, kiss her deeply and passionately.

"Mmmmmmn."

Her hands grasping at Sonata's rear, squeezing those cheeks tightly for a moment, before kneading them. With that it didn't take long for her dick to poke its way out from the front opening of those boxers.

The younger sibling kept that grin upon her face. Even as she was helped up to her knees, joining Aria in that deep, loving and sisterly kiss. It always felt so nice when she could get her sister to do these things with her. Often it was more difficult than expected, but today everything seemed to be working just fine.

Enjoying her sisters natural taste and flavour, the girl shivered and reached down to touch the tip of that lady-cock with her own fingers. Stroking her sisters stiff length and admiring the heat and size, even the shape of her sisters gorgeous dick. "Mmmmn." Sonata moaned happily, before breaking the kiss and panting hungrily.

"Sis... we probably don't have much time before someone walks in on us... so... um... fuck me, okay? Stick your dick right in my ass... fuck me, pleaaaase! Make me cum using my butt, for realsies! If you do... I promise I'll stop annoying you for the rest of the week, okay?" She'd chew innocently on her bottom lip.

Aria snorts heavily as she takes a breath in and exhales, "Tsk... your ass? Please... you always did like it up there though..." she mutters a bit, taking her hands to tug off Sonata's shirt. She thought to herself that if someone walked in, fuck it, they can see her railing her sister, or maybe join in once she was done with Sonata. Either way, she nudged and moved her sister to start tugging on those shorts as well.

"With how much you always beg me to breed you too? Geez... though I suppose if you really want it up the ass... fine."

Sonata shivered as she felt the chill in the air against her skin, making her squirm. Her naked chest exposed to that of her big sister. Then, she'd wiggle out of those hot-pants as she'd sit back on the bed, completely naked now. All on display for her sister. Once more, she'd turn and lay flat on her front. That bubbly backside facing her sibling, as she'd cuddle the pillow with both arms, underneath her chin and then she'd smirk.

"I wanted it in my ass... but... if you wanna cum inside... somewhere else, then... yeah, I won't stop you sis."

Aria shifts a bit to strip off that shirt, then moves enough to kick off her boxers as well, "Heh, it's fine, shouldn't be surprised cause your such an ass girl after all..." She nods her head some, shifting a bit to lean over to the nightstand to open the drawer.

Pulling out a tube and leaning back in. She popped the cap on it and started to drizzle the contents. Lube. All along that crack of that ass. She stopped once she felt it was enough, sitting up slightly to start grinding her dick along the lube covered areas. Hot-dogging it, as it were, making sure things are getting real slicked up there.

"Aaaaaah... it's so cold... nnnagh... it's dripping down, everywhere."

Sonata mumbled as she'd cuddle in against that pillow some more. Spreading her legs as wide as she could, comfortably of course. Then she'd feel that slab of sisterly meat slap against her cheeks, wedging between the cleft of her valley of flesh. Massaging up and down along the joint slit, she'd shiver and moan gently.

"Aaaah, yes... it's so hot and stiff... hnnnagh... I can't wait." Sonata whimpered, waiting now for her sister to finally start her penetrating romp.

The purple haired siren grunted lightly as she sighs a little as well, shifting a bit to take her hands to spread those cheeks, but she had to make sure she gave a good firm swat to each one as well. She got a bit more lube to trickle around that back door, taking a finger to prob and press to make sure she got enough lube leaking inside as well.

She would close the bottle and toss it aside, within reach just in case she needed more. Then, ass spread wide again, angling her tip to that puckered hole and presses herself right in. She knows her sister wanted to leak out her jizz, so she was going to just that. But she'll make sure to also give her a proper cream pie later, after another shower.

Dick easing its way inside, thanks to the lube, right to the hilt. She let go of those cheeks and relaxed there for a moment, grunting and groaning some before pulling her hips back and pushing forward, starting to get a steady pace going.

Sonata yelped out as her two cheeks were struck, causing a gentle jiggle too. The girl was very bountiful in the trunk and front areas. Natural siren beauty transferred to that of a human body, well, the results showed. Yet when Aria poked a finger inside her asshole, she'd groan gently and await the much bigger finger to make it's move next.

With that, she'd feel that cock push against her winking star and slowly it eased inside, it was painful as her sister was quite large - but it wasn't something she hadn't experienced before. After all her and Aria had there little moments together at times, often behind Adagio's back. As that cock shaped her asshole, she'd groan deeply into that pillow and whimper.

"Mmmnnnrarghh... yes...!"

Sonata groaned, feeling the entire shaft inside and they both paused. Until, Aria began that swaying motion. With her eyes closed, Sonata remained still and enjoyed that fucking motion her sister began to give.

"Hnnnnagh... y-yes... oh... fuck...!"

Aria groans as she planted a hand on Sonata's back, lifting up and thrusting down over and over. Oh this was good... not the greatest, as that ass was always a bittersweet way to go, but good all the same. Still, her sister wanted this, and well, how often does she give her sister what she wanted? So why not.

Aria shifts and adjust herself to get a better angle at things, starting to pick up the pace as well as she would go from a steady thrust to quickening jabs. At the end of this she will be jack-hammering that ass, but she's working to that point right now, keeping Sonata pinned to the bed, and just riding out that ass.

The younger sibling whimpered, feeling all that adjusting and moving around that Aria was doing behind her. Those firm hands upon her back, forcing the younger girl into the bed and essentially pinning her so she couldn't move. Her sister was so forceful when it came to sex, which was one of the reasons Sonata pestered her so much for it.

She was aggressive and forceful and Sonata loved that, when it came to being fucked. Being used as her sisters living flesh-doll. She also kept in thought that her sister had probably went sometime without climaxing, so she was also getting her right now at urging state. As the speed picked up, Sonata could feel that cock sliding in and out of her backside, ramming and rubbing against her anal walls; scraping her ridges and curves and every time Aria hilted; Sonata released various little squeals and squeaks.

"Aaah! Aeeeeh!" Her pussy was soaked, actually staining the bed too. But that was fine, surely Aria wouldn't care.

Aria wrapped her arm around Sonata, hugging her close, laying on her back, but positioned her legs just right to help drive her cock in and out of that ass. It almost seemed like she wasn't going to stop, even if she exploded her load inside. That ass clapped Aria's crotch, it echoed in the room each time they met.

Grunting, huffing, she hugged her sister as she got to that jack-hammering speed she wanted to get to. Making Sonata sink into the bed each time and bounce back to meet that cock with full force. Her body tensed up, that cock swelling up, the time was drawing near. The bite to Sonata's ear, then her neck helped give way to that.

The attack to Sonata's ear was more than enough to spike the sirens pleasure bar, already Sonata was peeping closer to her own orgasm. While they changed positions, it seemed that Aria had found her prime position for fucking that asshole right now. Sonata lay there, on her back now and took it like a bitch.

The younger sibling, grunting and mumbling out repeatably as she'd feel that cock bend and curve inside her anal chamber, poking and exploring around her insides. As they both hugged, Sonata wrapped her arms around her siblings own body and held tight; she wanted to hold out for as long as she could, wanting to join Aria in that joint-sister-orgasm if she could help it.

"Uuuuuuuuargh! I-I'm so close... Ariiiiiaaaaaaaaaaaaaa!" Sonata whimpered, as she'd grit her teeth and roll her eyes up into her skull, quim dribbling from her own little hole as it smeared all over her sisters own crotch.

Aria held onto that neck as she bit down a bit more, she was indeed going to leave a mark there after this was done. A few more moments of just ramming her cock deep within that ass, she gave one final thrust inwards. It was there Sonata could feel a sudden explosions of warmth rushing inside her, as Aria started to fill her depth with seed, painting those walls white. She kept herself buried to the hilt, but even that wasn't enough to keep most of that cum from splashing out around Aria's cock, pumping that ass full to where even still plugged, Sonata would be drooling with jizz.

As Sonata heard her sisters grunts, moans and then that sudden rush of heat within her. She knew what was happening, the sudden pike of pleasure and pain, combined. Made her squeal out and she'd feel the rush of her own orgasm during Aria's own. As her big sister was filling her up on the inside, Sonata was releasing her own sticky, sloppy mess of feminine love against her sisters lower regions too.

Plentiful squirts of lady-liquid oozing, squirting and splashing around their joint sexes. Truly it was a combined mess for the ages, something that they both enjoyed quite often together. "Aaaaaaargh! ARIAAAAAA!" Sonata screamed out, hands clenching around her sisters back and even scratching her nails into her siblings skin, as she'd try to turn her head away from those clenching teeth, that were pulling, tugging upon her ear.

"HNNAAAAGH!" Sonata did all she could and that was, at this moment, ride out that orgasm.

The older siren slowly eased up on everything, the biting, the grip, everything. She huffed and heaved heavily, as she kept herself hovering over her sister, buried deeply in that ass. She slowly, every so slowly, pushed herself up and fell to the side, laying on her back with a cum covered dick that was softening up after the moment spent.

Sweat dripping along her body, wiping her brow some as she shook her head. She's not done... but for the current moment, a breather was needed.

"Uuuugh, fuck... Sonata. I swear. Every time we do this, ugh... you get tighter. Or maybe... I'm leaving it too long between fucking people."

As Aria removed herself from Sonata's form, the younger girl remained on her back and panted deeply. Eyes closed and mouth agape as she tried to suck in as much air as she could. The siren whimpered as she'd place a hand between her legs, feeling and sampling the soaking wet patch that was her sex. As well as feeling the dribbling sensation that was coming from her asshole, her puffy ring twitching as some more leaked from it's insides.

"Uuuagh... I can feel it... leaking out, mmmmn..." Sonata was pleased with this, it was also one of the reasons she loved getting fucked in the asshole. To feel such messy things as this. With a satisfied face, she'd squirm and shake. "Aaaaauagh... thanks sis, that was amazing."

The older siren grunted softly as she chuckled, stretching out and shifting some more, "Heh... you owe me..." she mutters, shaking her head some though it didn't matter, she would get what she wanted later anyway, they both knew this.

Sonata slowly nodded her head. "Y-Yeah, okay... I'll let you do whatever you want, okay? Round two, three, four and five... and if you're still hungry after all that... then... you can just keep going, even if I pass out okay?"

Sonata giggled and draped an arm over her face, chest raising up and down as she mumbled gently.

"Mmmnn... whenever you're ready sis. Fuck me some more... let's get me pregnant!"
