Adagio grumbled as she pinned in a new pin against Sonata's hips. "I swear... if your tits get any bigger Sonata I'm gonna fucking kill you." She muttered as she stood back to get a look at the new hemlines she had for Sonata's new dress.
Right now it looked just a little incomplete, she was hoping to add a frill at the hips or something to the hem of the skirt. Rarity was working in the other room right now and Adagio ran a hand through her hair, which was presently done back in a ponytail as she considered what to do.
"How does it feel right now?" She asked.
There was some Christmas ball that all three sisters had been invited to mainly because they claimed they were above twenty-one and all hot as shit, Adagio had been making the dresses for the three of them. Well... Aria had opted for a tux, but... she and Sonata were getting new dresses. It helped being a professional seamstress now.
"It feels pretty good, Dagi! It's a little snug, but it feels really good against my body! And... I can't help it... my boobs are just big, it's not my fault."
The dress itself was coloured a cyan blue, nearly matching close to that of the ocean in a bright blue and clear sky. Perhaps even a lighter shade of her hair, though Sonata smiled as she had Adagio work upon her body like this. It was a nice feeling, having her older sibling do something like this for her.
Even if Adagio's newly obtained job, working as a seamstress in Rarity's boutique was unexpected. But they all needed a job and money, not to mention the Ball that was coming up. It was going to be something new, she was looking forward to such an event.
Adagio was admittedly looking forward to it to, if only because she might nab herself a hot, rich boyfriend she could mooch off of for gifts and the like. It was a fun idea if nothing else. Right now though she was a bit preoccupied with Sonata's dress. She rubbed her chin for a moment before bringing a sash up and wrapping the silk around Sonata's waist to make it into a bow at the back of her dress.
"Well, if nothing else, your ass is a present now." She teased as she gave Sonata a little goosing on that peak tier ass of hers. "Where does it feel snug?"
Sonata released a cute squeak as her backside was made presentable via that cute silk bow. She felt amazing and the fact that Adagio was now teasing her regarding this, made her feel even better. It always felt good when her big sister complimented her.
"It feels kinda snug around my butt... and my boobs... and down around my uh... my veegina."
The girl said incorrectly, twisting and turning slightly as she'd observe herself in the mirror that was behind Adagio and to her side, this dress looked amazing and truly brought out the curves of her body. Sonata was a bit meatier than the other two sirens, but that made her perfect bait for when they tried to screw over easy prey.
Adagio huffed as she unpinned a little of the extra length around Sonata's bust, letting it fill out more as she grumbled to herself about her sister's ever growing tits. How come she didn't get big tits? Adagio then crouched down to work at the back, as much as she wanted to show off Sonata's butt, if it didn't feel comfortable it wasn't worth it, so she let that out a little as well.
"Wait... how does it feel tight around something you don't have..."
The blue haired siren paused as she heard that question, feeling a gentle blush in her cheeks. Even still, as Adagio worked at those adjustments.
"I uh... well... I miss it, okay? It's still weird having this dick... and it's really tugging on me."
Sonata frowned slightly, but it probably came across as cute frustration, considering she was slightly showing a bulge through her dress due to how tight it was around her thighs and lower region.
Adagio grimaced as she reached up and pinched that dick. "Well if you went to Twilight for help, I'm sure she'd be able to reverse whatever you did to you and Aria. Although, maybe the big issue is Aria never wants to go with you so the spell cant be fully undone. Anyway, I think you're just going to have to wear some compression shorts so you don't just bulge out and get a big tent when we go to the Ball."
She looked up at Sonata for confirmation that her littlest sister would remember to wear special underwear.
A small grunt escaped her pouty lips as she felt Adagio pinch her length through that tightly fitting dress. Sonata heard what her sister suggested and with a nod of her head, she'd acknowledge it.
"Yeah, okay... I'll get some... shorts or something, I promise..."
Sonata released another annoyed grunt. She liked having this newly obtained equipment, but she did miss having a vagina too. Perhaps maybe, she needed to actually go and see Twilight regarding this; maybe talk with Aria too. With a wiggle of her hips, she'd gaze down at Adagio as she stood there.
"...Mmmmn..." It was an annoyed groan. "Dagi..."
Sonata squirmed on the spot, wiggling and showing signs of growing frustration; her little secret getting bigger with each passing second.
Adagio rolled her eyes, she shouldn't have pinched Sonata and her new virgin dick. One blowjob had not been enough to quell the girl's horny nature as a siren, let alone how it felt to have a new sexual appendage. Adagio rubbed her hand over her face before waving her hand. "Just, let me help you out of that dress so I can work on the seams, then you can go into the back room and uh... deal with that. I'll be in in a minute if you need any help, I just need to put the dress up so the seam pins stay in the right place. Shouldn't take long."
Adagio then helped Sonata strip out of the dress, leaving her in a bra and rapidly growing panties. "Go, scoot, before someone comes in and sees you."
With a quick nod, she'd allow Adagio to help her out of the dress. Now she was standing in her cute lingerie and already her panties were beginning to tent and poke up, her bulge growing and starting to stress the fabric that was her panties.
"A-Aaah... okay... I'll go and wait for you. I-It doesn't have to be much, I know you're busy... it's just after last time... I wanna..."
The blue haired siren paused with her words and released a long, frustrated sigh and nodded yet again. Now, she'd make her way into the changing rooms, closing the door behind her - but not locking it. Once Sonata was inside however, she'd sigh and look down at her now fully, standing girl-cock which by the way, was peaking out the top of her panties.
"Uuuugh... it feels so good." She mumbled.
Reaching down, Sonata tugged her panties down her legs and off at the base of her feet, casting the aside. Once she was free of the tight fabric, she'd sit back on the bench within the room, spreading her legs and allowing both her heavy sack and she-dick to remain untouched and free. With a throb on occasion, she'd slowly reach down with one hand and grasp herself around the base, giving it a gentle upward stroke.
"Mnnnagh..." Leaking at the tip, it was already driving her into a needy state.
Adagio prepared herself quietly for what she needed to do next, she shifted a little uncomfortably in her shorts before she ducked out to the main room. "Hey Rares, I'm done with Sonata, I'm just gonna be in the back helping her get ready to head out. See you back here in twenty."
Rarity gave a little nod before Adagio ducked back into the back room, heading over to one of the changing rooms.
Opening the door, she caught sight of Sonata just stroking herself off. "You'd better not get cum on the mirror in here, it's a bitch to clean." She said as she shut the door behind her and wiggled her hips, sliding her shorts and panties, exposing her own hips before she simply leaned to have a seat against the bench, reaching over to take hold of Sonata's dick, stroking it for herself.
"So... you want to fuck me this time, yeah?"
As the door opened, Sonata looked up with a worried expression. Perhaps it could have been Rarity, but thankfully it was just Adagio. Goodness, that could have been a whole new problem on it's own. As her sister entered and the closed the door, Sonata's eyes watched as she stripped of her shorts and panties. Oh this was quite a beautiful sight.
"Ahuh." Sonata merely responded.
Releasing another gasp, though heavier this time as that hand wrapped around her prick. Stroking it up and down, sending shivers throughout her entire body.
"Mmmnaaah... yes... Dagi... I wanna see how you feel this time!" She said.
Flushing quietly, she shifted on the bench before getting up and just turning around to put her hands on the bench and push her hips out. "Fine... just be sure to put it in the right hole okay?" She said, spreading her legs and reaching under her body to spread her sex open to show off that she might be a little aroused already, but shut up about it, she's just horny in general, it wasn't like she was thinking about this too or anything.
Either way, she turned to look back at Sonata. "Don't make a bunch of noise okay? Rarity's in the front of the store and I don't know if she'll be back here to seam someone up or something. So don't moan like a slut."
"Don't moan like a slut? But that's gonna be difficult, Dagi..." Sonata pouted.
The blue skinned girl stood up from the bench, after Adagio assumed the position and she'd stare at that delicious opening. It looked so accepting and warm, it made the girls cock throb without thought. Sonata pushed in close behind her big sister and allowed her hands to rest upon those supple, shapely hips.
"Okay, so... this hole."
Sonata said as she'd take position and place the head of her needy bitch-cock against the spread opening of Adagio's sex, of course with guided help of her dearest sister. With a simple thrust, she'd push her entire eight-inch length into her sisters accepting slit, and of course release the most satisfied of moans.
"Oooohhhuuuuuaaggh..."
Adagio bit her lip as she felt her sister starting to slide right into her perfectly prepped hole. She flushed, shivering as she arched her back and pressed her hips back a little further to make it easier for Sonata to hold on and get in better position. "Mmfh... r-really... cant believe you cant j-just get a girlfriend f-for this kinda stuff..."
She huffed as she clutched at the bench, wiggling her hips a little and maybe forgetting that she's in front of a mirror, because her face is definitely enjoying this more than her voice is relaying as her lip is quivering and her eyes are shut tight.
"It feels... so good... Dagi. You're veegina feels amazing... it's so tight and waaaaaarm, aaaaah... I feel like I could burst just sitting here."
Sonata mumbled as she finished those words. She didn't move either, for the moment she remained still and un-moving and merely enjoyed the heat of her sister sex. It was embracing and she did feel like her dick was melting. With an ease outward, she'd draw her length out of that delicious sex until two inches remained inside... only to push straight back in again.
"Uuuuugh... I-I don't know... it just feels so good!"
The girl started to pick up the pace however, the pleasure was starting to flood her mind and while it felt somewhat similar to her sisters mouth, it felt so much better. Serving to go faster and faster now, picking up speed and beginning to clap her hips against her sisters ass.
Adagio kept her eyes shut tight, feeling that mating clap against her backside. Thrusting deeply into her warm socket and that sisterly shaft, burying and rubbing against her very insides. Brushing against each ridge that was contained within, making her moan gently as she tried not to emit much noise incase Rarity heard them.
"Mmmmrrrrggh... ugh, this is too good... I almost missed this feeling..." she'd mumble.
The blue haired late teen kept up her advances though, bucking into her sisters plush backside. Ensuring her prick would enter fully within her sisters gorgeous sex, feeling those slick and velvet walls squeeze and milk her like it were the last cock on the planet.
"Yes! Dagi! Uuuuuwagh... it feels... too good... I can't hold back!"
As the honey haired siren remained against the bench, her slender and well-painted fingers grasped the wood and kept herself as well supported as she could. Sonata was really pounding into her and the frantic smacks of their combined flesh - echo'd through the changing room, followed by small and cute gasps of pleasure as Adagio tried to remain as reserved as possible.
"Uuuuagh... Sonata... h-hurry up, before... Rarity comes looking... uuuuagh, you stupid dork..."
"It feels so snug... like... my bed in the morning, I just... don't wanna leave!"
Sonata groaned out as she'd quicken her pace, humping faster and even clenching her sisters plush flesh that much more. It was so soft, Adagio herself was so soft and cute; Sonata was losing herself, she'd been backed up for a while and this wasn't helping the situation.
"Uh! Uh! Uhhhhh! Oh! Oooooooagh, feels so good!" Sonata groaned heavily.
"S-Shut up, Sonata.... uuagh... you're gonna get us caught...!"
Adagio spoke out with worry, the last thing she needed now was to have Rarity catch them like this. Rarity was already a germophobe and to find them messing up her elegant changing room like this, would send Adagio out of the job faster than Pinkie Pie eating a dozen cupcakes.
But this didn't stop Sonata from thrusting as hard as she could into Adagio's pink depths, the girl was fixated on pleasing herself, even if it mean't risking detection from the boutique owner. Sonata panted heavily, lolling her tongue out over her bottom lip as she'd continue to slap against her sisters perfect slit.
"Aaaaaaaaaaaaah, Dagi! I'm so close!"
"W-What?! Don't you... uuuargh... don't you dare come inside me!"
It seemed that Adagio was pretty clear on her stance with Sonata potentially climaxing inside her, though it was magically obtained, Sonata's cock. It wasn't clear on whether or not she could actually impregnate her older sister, but it seemed that Adagio wasn't willing to find out.
"I won't... I-I promise I'll pull out in time, okay?!" Sonata replied.
"You better! Or I swear... I'll kill you!" Adagio angrily stated.
The lewd and loud claps could be heard throughout the small room they were in, it echoed and the sloppy and slick noises that accompanied it could also be heard. Yet, both girls were panting and groaning like bitches in heat. Something Adagio not expecting, though probably should have; was happening.
"Aaaah! Da-Dagi! I can't... I gotta...!"
"Wait, Sonata... what are you gonna-!?"
Within a mere moment, Sonata humped against her sister with such vigor; right up until the last moment. Grabbing her sisters flesh tightly and pulling her back against her hips, Sonata made sure to hold her sister firmly against the base of her cock.
"UUUUUUUUUUGH!"
Sonata groaned deeply, arching her back and staring up toward the ceiling as she'd ensure her dick was fully inserted into her sisters honeypot, allowing her heavy balls to do the rest. With heavy groans, Sonata pumped load after sticky load into her delicious sisters slit, filling her nicely with hot siren love.
"SONATA!" Adagio yelled.
"Feeeeeels... so good!"
"Uuuuuagh... Sonata! S-Stop... uuuagh... you're filling me up! It's too much...!"
Adagio couldn't do much at this point, she grunted and whined deeply. Feeling her body press against the bench, which she was using for support. Though right now, Sonata was keeping herself locked against her. Applying pressure and keeping her firmly in place, until she finished.
During that time, the honey haired siren could feel the entire load blow within, and despite her feeble struggles, she wasn't able to fend off Sonata's messy finish. Biting down on her lower lip, all the older sibling could do was merely endure.
Whenever Sonata had finally finished, she'd lean forward and against Adagio. Panting heavily and feeling good, a tingling feeling all over and she'd allow her fingers to grab and explore her sisters flesh with tender grabs.
"Aaaah... so-sorry Dagi... I came so much... I know I promised but... ugh..."
"It's fine... Sonata... I'll just kill you later... when we get home."
"Aaaaawww, I'm soooooooorry...!"
"Apologies won't work this time... I said-"
"Are you girls okay in there? I mean, you've been back here an awful long time."
Rarity spoke from the other side of the door, having given it a gentle knocking. It was then that both Adagio and Sonata felt that shadow of dread loom upon them and then they'd quietly look at each other.
"N-No... it's fine, Rares... Sonata had an... accident... and I'm helping her with her clothing, we'll be out in no-time!"
"Yeah, sorry Rarity! I did a boom-boom!"
"Uh..." Rarity said in confusion.
"No! You didn't Sonata! Sorry, she's just being an idiot, Rares! Be out sooooon!"
Adagio was quick to reply, trying to save the situation despite being left in this sticky situation. Of course she delivered a firm sideways smack to Sonata's arm in response for that reply. Which surely made things that much more awkward.
"Uh, well... alright darlings, just head on home when you're both done. I'm stepping out for awhile and I'll return later. Also, thank you for your work today Adagio, you're making great progress."
"Oh, thank you Rares. Told you I was good with my hands."
"Heeeeeeeheehehee." Sonata giggled quietly, before she was struck again by Adagio. "Ow!"
The clicks of heels could heard, as Rarity walked away from the door and slowly Adagio pushed Sonata off of her backside, leaving that gunky and messy feeling behind. Heavy globs of siren sauce spilling from their joined bodies, onto the floor and Adagio released a heavy sigh.
"I'm never gonna get home, am I Sonata..."
Adagio said with an irritated voice, observing the mess of the room and themselves. It was very messy, Sonata had really released quite the load and now she'd have to spend the next thirty or so minutes, making sure they could get home with some modesty and leave Rarity's changing quarters the way it was found.
"It's okay Dagi, we had fun right? I mean, you felt so good..."
"I'm a siren, Sonata. I'm suppose to feel good."
"Oh. Right."
"Listen, let's get finished here... so we can leave, before you decide to fuck me again."
"If you want, we can when we get home!"
"Maybe... don't push your luck, or i'll lock you in a cage."
"Oh, okay... I'm sorry... please don't, Aria already did that and it wasn't fun."
It was then that a crafty smile appeared on her face and she'd think things over. Perhaps this was an interesting way to go, torment and tease Sonata to the point of desperation. Only then would maybe the girl would start listening and paying attention. A possible method of puppy-training for her little sister.
"Oh-ho-hooooo... we'll see, Sonata. We'll see."
