It was a boring weekend evening. The siren household was nice and quiet, which was rather strange considering Sonata was usually doing something to bring noise around the place. However she was resting upon the couch, eyes closed which then opened when her big sister, Aria sat next to her.
"Hey sis!" Sonata spoke out.
"Yo." Aria meekly replied, clearly bored.
"You wanna fuck me, sis?"
"You in heat or something?"
Sonata paused for a moment, as she'd stare toward the ceiling in deep thought.
"No, I don't think so. I mean, I don't feel hot."
"... In heat is like needing to breed and procreate."
"Oh! Well, I mean... fucking feels good, right?"
Aria sighed and closed her eyes, trying to ignore the situation which she knew all-to-well that it wasn't going to be that easy.
"Well... yeah."
"So... why don't you fuck me?"
"I don't know, why don't you fuck you?"
"Because it's soooooo boring that way!" Sonata groaned with frustration.
"Pfffft, you would say that."
"Hmph. Fine, whatever." Sonata grumbled, as she'd fold her arms.
"I mean, what's in it for me?"
"Pleasure, orgasms and I uh... I'll buy you those milkshakes you like."
Sonata had learned recently. That her big sister, Aria, had found an affectionate like and desire for milkshakes of the strawberry kind.
"I don't know, don't sound like there is much in it for me." Aria rolled her eyes.
"Aw, c'mon! Okay, two milkshakes!"
Aria sighed and looked her sister over, adjusting herself and opening her legs slightly as she made herself more suitable for approach.
"So, you really want to get railed, hm?"
"I mean, if you're wanting too. But I do miss feeling that dick inside me."
"Well, yeah, I am... just I don't know... amusing that you just straight up ask for it rather than trying to be coy like you usually do."
Sonata grinned as she heard this.
"I dunno, I guess I just wanted to be more direct this time. Cause when I be coy, you just ignore me. Or punch me."
"I mean, I punch you anyway at times, but fair point either way. Well, then I guess just... how to go about it." Aria sighed deeply.
Sonata would give her a grin and leaned up against her beloved sister and placed a hand upon the girls thigh. "Yeah, how DO you wanna go about it, huh?"
"That's why I am asking you, idiot. I don't care what position really, but unlike you, I can't snap a finger an be instantly turned on."
Sonata sighed gently and leaned in against Aria's right ear, as she was seated on the girls right side. "Okay, let me fix that problem - kay?"
The siren leaned in, pressing her lips to her sisters lobe, nibbling, suckling and even grazing her teeth against it. While doing this, she'd move her hand up toward the girls crotch and gently tease and poke it, rubbing her groin all over.
"Mmmnmmm, let's get you hard first."
The purple haired siren chuckled faintly, if her sister really wants it, she would have to work for it, which is amusing to get her to do at times, and she seems to be doing just that. Shifting a bit, closing her eyes, feeling the nibbling on her ear, the suckling. Then that palm upon her crotch like that too, causing her to breath in and exhales slowly, it would indeed stir something up within her pants there, causing her to also lick her sharp teeth and lips a bit, "There you go..."
Sonata merely smiled as she continued to brush her tongue, teeth and lips against her sisters ear. Slathering it in saliva and she'd mumble lightly. "Mmmmnnn."
Deep, heated breathes layering over her sisters soft skin. While her hand squeezed and groped at her sisters groin, working that hidden cock up lovingly. When she felt it become hard enough, she'd unbutton her sisters pants with that one hand and tug down the zipper, trying to wiggle her fingers to fish that cock out.
"Mmmnmmm, yesssssss. I want you, sister!"
Aria huffed a bit as she leans her head back and groans lightly, she couldn't be turned on whenever she wanted too like her sister can, but she can be worked into the mood thankfully. When she felt her sister starting to undo her pants, she would lift her waist up to help push them, and her boxers down, kicking off her boots as well so her bottoms can come right off there now.
"On the lap, bent over, on your back... On your back, we haven't done that in a while."
Sonata indeed helped her sister remove her panties and undergarments. Yet when she heard the desire from her sisters lips, she'd perk up with joy. "Oh! Fuck! Yes, okay!" Sonata didn't waste anytime and she'd remove herself from Aria's side and quickly she fired herself onto the couch, back downward and she'd grin like the cat that got the cream.
"Okay, I'll let you do what you want. Just... fucking give it too me!" Sonata sighed, biting her lip as she'd look up toward her bestest sister ever.
Aria snorted softly, gosh damn this girl. No shame, she couldn't help but chuckle to herself a bit there, shifting a bit and adjusting herself some to pull away so Sonata could flop onto her back and give her that cat like grin. Aria would then move in to start undoing that skirt, and panties as well.
She would grasp herself to start stroking and helping herself get harder and fully erect as she would move to place herself between Sonata's legs now.
She'll let her cock flop right on that pussy, before grinding it up and down like against it, making sure to coat, not that it really needed it, that shaft of hers within that glistening juice of her sisters.
The baby siren wiggled and helped more her body, so that it would be easier for her skirt and panties to be removed. When they were, she'd spread her legs and allow her sister to get between them; so that she could get furthermore into place. "Mmmaan... fuck... I can feel your hard dick against my pussy, Aria." Sonata chewed upon her lip.
"Fuck... I want you." She'd further state. Then she'd feel that hard dick, smack against her sex and grind itself against her soaked pussy. Already Sonata was wet, and she'd be glad of her sister to enjoy the free sample of lubricant that was naturally supplied by her meat-socket. Waiting for insertion, she'd shiver and tremble gently.
"Y-Yes... please..."
Aria snorted once more, man her sister really must be in a mood if she's like this already. Even so... well, it doesn't matter, it's happening anyway. Aria would grasp her base to help keep herself stable as she pulls back just a bit to line her crowned, swollen head up to Sonata's entry way, then slowly started to press herself right in.
Once she felt she was in enough to let go, she does that and plants her hands upon the back of Sonata's thighs to help keep those legs up and apart. The usual pissy siren pushes herself all the way in, rocking and rolling her hips about to cause her cock to just grind and slide about inside before actually starting to pull her hips back and thrusts right back in. A slow, but rather rough thrust each time she does.
Sonata hissed gently as that cock moved against her opening and inside it went. This made the younger siren perk up and even arch her back, muffling out with pleasure. But when Aria pushed further inside, she'd groan out deeply and squirm.
"Mmmnargh... fuck...!"
Sonata squirmed against her sisters body, feeling those hands upon the backs of her thighs, holding up her legs and allowing Aria to support herself. As she'd continue to push that cock all the way inside. Sonata panted deeply, feeling her insides grip and squeeze that sibling cock. Already going to work on her sisters dick, milking it almost instantly. Releasing deep grunts every time Aria thrusted into her tightly gripped cunt.
"Ugh! F-Fuuuuck! Y-Yesssssssss, ugh!"
Aria would huff hotly as she closes her eyes and leans her head back, keeping that steady thrust into her sister like that. Making sure to have her hip crashing up against Sonata's own crotch, making that nice clap each time they connect. Aria grunted each time, moaning as well as she would then looked down at her sister. Moving a hand off a leg to reach down and starts to tug up that shirt and bra to get those breasts free and bouncing as well.
She then takes a hand to grasp and grope upon one of those tits, kneading, fondling, while thrusting against her sister more and more. As she did this, she started to thrust herself faster and faster as well, huffing and puffing.
Sonata leaned her head back, enjoying the very feeling of having her sister rail her. The very sensation of that cock inside her, pushing out her walls and feeling those balls slap against her crotch. Both hip and crotch meeting and kissing each time. The young siren whimpering as she felt Aria thrust the entire way inside.
"Uuuuuagh! F-Fuuuuuuck..."
She'd bite her lip and drape an arm over her face, enjoying the feel of pussy being destroyed by her sisters thick, fat cock. When her breasts were freed next, she'd gasp out sharply as Aria's hand made claim to her plump, perky breast. Kneading and squeezing it as if it were a stress-ball.
The girl whimpered with delight, she was having fun. She didn't even care about orgasming, she was getting off on the thrill of having her sister fuck her meat-hole like this. The sheer apparent human taboo of the situation, while they both basked in lust.
"Fuck meeeeeeeee! Uuuuuargh, I wanna feel you cum inside me!"
Aria snorts and huffs heavily, hearing her sister's cry for more practically, to cum inside her as well, how wouldn't that drive someone into that mode of wanting too? Aria would give that breast a firm squeeze once more, even playing with a nipple for a moment before pulling that hand back to place it back on that thigh.
She would adjust her legs a bit to help her get a better position and angle so she can start doing what Sonata wanted her to do. Thrusting more wildly than before, balls slapping up against her rear as well, the sound of that cock slurping and the slick sounds of it going in and out would hit the ears of anyone near by as well as the 'plap' sounds too.
Aria shut her eyes, gritting her teeth and snorting heavily, groaning through said teeth as she squeezes her hands on those thighs, "C-Close... fucking hell I am close..." She would say, not just yet, but indeed any moment now.
Sonata groaned sweetly, enjoying the feel of her sisters hand upon her chest. Squeezing and enjoying the fat, soft and plush feel of her large breast. Playing with her nipple too, which was causing Sonata to squirm and shiver with intense pleasure in that little nub.
"Mmnph!"
The youngest siren squealing as she felt Aria pick up her pace, changing positions into that of a better angle and now she could feel that cock slide into her sex, penetrating her with more vigour and assaulting her insides and every ridge that her sex carried as a defence to suckle upon that fat prick.
As that cock frantically buried itself in and out of her slot, meshing against her sides; she'd squirm and arch her back, hands reach out and gripping the couch. While her legs wrapped around her sisters back, keeping her firmly in place.
"Mmmrgh! Y-Yes! Fucking... do it! Make me pregnant!"
Aria grunted lightly at that last thing, then a snort came from her nose as she shook her head, her sister, she swore, what to do with her. Right now, she was about to fill her to the brim with seed and that's what she was going to do. Slamming herself with each thrust, causing not just her sister to bounce on that couch, but the couch to rock and groan under their weight and movements as well.
May need to replace the springs in the couch as well later, after this, with how much vigour she was putting into her thrusts against her sister. A few moments later she was really trying to go at it with her all till she finally slams herself hard and deep within Sonata's depths, then gritting her teeth tightly and groaning loudly through them as Sonata can feel blast, after blast, after blast, of seed shooting to her furthest depths.
Not just strains, but thick globs of it each time. Aria jerks and twitches, making sure to keep herself buried as to assure none of the cum would come out, however she always over produced and it would always come spurting out around her cock, just oozing down that ass and onto the couch as well once she was all said and done.
The younger siren panted deeply, feeling that cock of her sisters really work at her insides. She was a hot, drooling mess right now. Feeling her sisters prick, churn up her insides like butter. The younger siren whimpered and clawed the couch, then she'd grunt and squirm.
"Hnnnh! Y-Yes, I can feel you... fucking... hnnngh, yes!"
Sonata groaned out. Feeling that cock erupt within her. It was like an organic life-filled volcano. Her sisters sauce shooting inside her, it seemed her sister was backed up somewhat. That thick white and sticky cream, oozing from around her cock and leaking over Sonata's own sex. Dribbling down and spilling right out over the edge.
This made Sonata twitch and the girl arched her back, hitting her own climax at that very moment. The sheer feeling of her sister, spunking inside her, got her off on it's own. Not to mention the feel of it. Sonata's body jerked and shook, making her whimper loudly.
"HNNNH! C-CUMMING!"
Squiring out her own love right up against her beloved sisters own groin. Until she was finished. Leaving them both a hot, stick mess of siren love. "A-Aaaah... fuuuuuck... you came so much inside meeeee... I'm gonna get pregnant..."
Aria drapes an arm on the back of the couch, panting, huffing heavily, rolling her head around some as well as she chuckles, "I mean... surprised you never have been before, but shall see indeed if that is the case..." she chuckles a bit more, shrugging a shoulder as she kept herself inside her sister.
She would give a quick little thrust or two before slowly pulling herself out, hissing a bit at the feeling of it all and how sensitive she was as well before gasping and plopping back onto the couch, "Damn, no Dagi to clean this up either..." she chuckled.
Sonata shivered multiple times, especially when her sister thrusted back into her. Spiking that pleasure gauge up some more. The blue haired beauty mumbled gently and panted deeply, sprawled back against the arm of the couch and looked back toward her sister.
"Mnnagh... f-fuck... yeah... yeah... I know... uagh... fuck... we'll see I guess."
She'd mumble, looking down between her legs and watching as that excess amount of semen had started to pool onto the seat of the couch.
"Mmmagh, fuck... couch is ruined. Mmmmrgh, that's our fault, heh. Your fault... cause you came so much in me, you're totally the worst sis."
Aria smirked as she'd start to stroke herself gently.
"Don't worry you little bitch. Next time, I'll make sure there's no mess. I'll just have you chug it down instead. Hehehe."
"Oh! Or we could have Dagi clean us both up!"
"Heh, not a bad idea. Give her something to do."
Sonata grinned just as Aria would, both of them thinking that devious little thought together.
"Then it's settled. Next time, we'll just use Dagi." Aria smirked.
Now it was time to clean up, before their little session was spotted by a particular older sibling. However a certain plan for their next session was already in the works.
