Adiago Dazzle sat in her bedroom, reclining comfortably at her desk. Wearing comfortable silk pajamas, she cradled her head in one hand while handling her computer mouse with the other. The browser window was opened to a shopping site, and Adagio was planning on whittling the evening away shopping for racy new outfits.
However, just as she had scrolled down to spy a particularly slinky dress, there was a rapid series of knocks on her door.
Adagio sighed. Such enthusiasm could only mean one thing. “So much for peace and relaxation,” she muttered to herself. Then, much more loudly, she added “Come in, Sonata.”
The door flew open immediately, revealing a visibly excited Sonata Dusk. You could tell because of the stupidly large grin on her face and the fact that she was bouncing up and down on the balls of her feet. She was also holding something behind her back.
Taking a deep breath, Adagio spun her swivel chair around to fully face her sister. “Yes?”
“I made something really, really neat and I want you to try it out!” she exclaimed, zipping forwards.
“A present? For me? You shouldn’t have,” said Adagio sarcastically.
“Actually, it’s for all three of us, but I’m not sure Aria is gonna like it very much,” said Sonata.
Though she was slightly afraid to find out, Adagio had to ask. “Ok, what is it?”
Sonata, her smile redoubled, pulled out what she had been hiding: a small, black tablet and two short colored controllers.
Adiagio’s brow rose. “Isn’t that just your game console? The… Nintendo Switch, or whatever?”
“Yes, but it’s what’s on the console that I wanted to show you!” Sonata elaborated.
Adagio had figured as much. “Ok, that makes sense, but why in the name of the tides does the red remote have a condom on it?”
Sonata glanced down at said enrobed controller. “Because I programmed it to be a vibrator!”
For a few moments, Adagio’s brain ceased functioning. “Huh?”
As a visual aid to her impending explanation, Sonata turned on the Switch’s screen, revealing a large array of white boxes on a black background. “So, you remember how I got myself Nintendo Labo the other day?”
Adagio blinked at her. “The stupid cardboard box that’s supposed to be a robot somehow?”
Sonata nodded. “Yep! Turns out there’s a mode in the game that lets you program your own creations! And the first thing I thought to do was turn a Joy-Con into a vibrator!”
“Wait, those are seriously called Joy-Con? And they’re vaguely phallic-shaped? I suppose this was bound to happen, then.”
“Exactly! So, will you try it out for me?” asked Sonata. Then, the leaned in closer, adopting a mischievous tone. “It has HD Rumble~.”
“Oh, why not,” replied Adagio. Sonata wasn’t going to leave until she agreed anyway. Plus, free new sex toy.
“Great!” Sonata then hopped onto the bed, patting the spot next to her. Once Adagio was lounging in position, Sonata passed her the Switch. “So, the Joy-Con with the condom on it goes in your pussy, obviously. The other controls the frequency of the vibrations. Just press up on the stick to increase the speed and down to decrease it.”
Adagio turned over the blue device in her hand. “That’s it? Alright.” Knowing Sonata, there was probably some other surprise in store, and she knew better than to pry.
Without wasting any time, Adagio dropped her pants, and then pulled down her lacy black panties. For most people, allowing one of their siblings to watch them masturbate would be extremely uncomfortable. But the Sirens had been living together for over a thousand years; any semblance of awkwardness between them had long since eroded away.
As Adagio lowered the Joy-Con towards her exposed labia, she pressed her thumb onto the other one. Sure enough, the controller began to shake within the condom. As she brushed it gently across her clit, a shiver went up her spine. “Yeah, that’s vibrating, all right.”
Sonata silently gestured for her to continue.
Shrugging, she did, conjuring an appropriate image - that of an oiled up, well-endowed robotic hunk - in her mind as she slowly increased the speed of the vibrations. Eyes shut, Adagio’s legs pulled themselves apart by reflex as she savored the familiar sensations running though her.
However, as she was just starting to push at herself with real force, Adagio nearly dropped the thing when a masculine grunt emanated from the console.
Sonata giggled at her, a hand covering her mouth. “I, hehe, added extra realism.”
Adagio took a second to recompose herself. “That you did. I’m impressed.”
Now that she was expecting it, Adagio had to admit that the synthesized vocals were a great idea. Keeping her eyes closed, she could almost see the buff specimen of hard chrome in front of her as she kept rubbing herself down steadily harder with the makeshift vibe.
Only when her cunt had been sufficiently moistened and her juices were enticingly dripping onto she sheets did she plunge the Joy-Con inside. The shape was like nothing she had ever taken, and Adagio couldn’t help but moan herself.
Body and mind craving more, Adagio thrust it in deeper, back and forth with the occasional electrifying twist to the side. As the odd contours of the buttons brushed back and forth against her sensitive folds, the deep moans from the speaker changed in pitch. It was a totally reasonable approximation of how an actual guy would react to fucking.
“This is, unf, pretty good, Sonata.”
“Ah, but it could be better,” she said, suddenly reaching over to slide her hands down her sister’s blouse from behind.
Adagio gasped as her outgoing sibling’s hands groped at her boobs in just the way she liked it: hard. She pictured the robot from her fantasy caressing her roughly with its hydraulic arms, far mightier than any mortal man’s, as it pistoned in and out of her snatch with tireless vigor. It was the thought of a partner that could keep pleasuring her forever that pushed Adagio over the edge.
Not bothering to stifle her scream of ecstasy, Adagio kept raising the vibrational speed ever higher as she came, shaking in her sister’s grip as she sprayed fragrant femcum into the air. The orgasm lasted for what felt like hours before the controller slipped out of her pussy with a wet plop.
Panting in the afterglow, chest heaving and hair matted, Adagio turned her head to face Sonata. “Ok… I think this is the best sex-related gift you’ve given me since that slave harem back in Saddle Arabia.”
Squeeing, Sonata dove in for a hug. “I’m so glad you like it! Feel free to use it whenever you want!”
Adagio chuckled, patting Sonata’s head affectionately. “I think I’ll take you up on that offer.”
Author's Note
Contrary to what my avatar image implies, I unfortunately do not have a vagina. Otherwise, I would have certainly made this Toy-Con myself in physical space. Feel free to do so yourself if this concept pleases you.
