Work Text:
It's a lazy day for Sandrone during her stay in Fontaine… well, as lazy as could be for a workaholic. She is hunched over a desk with schematics relating to her newest robot assistant, Fagio, and working on assessing PCB's for finer motor skills.
Unfortunately for her, there is also a goddess joining her on this lazy day. A real pain in the ass goddess who would not leave her side ever since they became reacquainted.
“Sandrone,” Columbina calls out distractingly, obnoxiously leaning onto her side, ignoring that she is actively working on soldering a circuit board.
“Hey Columbina, Watch yourself! Can’t you see I'm working on something here?” Sandrone pushes Columbina away lightly but it was enough to cause her to sway and stumble.
“Oof, you just pushed me Sandrone.”
“I did.”
“Are you going to apologise?”
“Absolutely not you attention seeker,” and at that, Sandrone refocuses her gaze back to her work.
Columbina lets out a small chuckle before shuffling back to Sandrone. Instead of attacking from the side again, she settles into a more comforting position. She rests her chin on Sandrone’s head, being mindful of the key on her back and standing slightly askew. Today, Sandrone’s bonnet is off and her signature bun undone. It felt unfit to have her hair loose during delicate work, but it was meant to be light so she wears it that way anyway. What didn’t fit, however, was Columbina aggressively sniffing her crown while draping her arms over Sandrone’s front, playing with her wavy brown hair that cascaded on her, being careful not to touch her bosom.
Sandrone, acutely aware of Columbina’s movements, maintains a keen focus on her task. Columbina actions at that moment technically aren't anything worth admonishing, and to say something would be to lose to Columbina’s mind games.
The sounds of soldering and the gentle, constant clink of Sandrone’s perpetual key fills the silence. Columbina takes a handful of hair in her hand and lets it fall between her fingers, its soft and silky texture tickling the both of them as she repeats the motions.
“...Got something on your mind?” Sandrone says, breaking the silence.
“Mhm, your hair is still so nice and smooth to the touch, I’m having trouble keeping my hands to myself.”
“Hmph, when have you ever?" Sandrone scoffs, "You are just like an overly curious blubberbeast.”
“Does that mean I'm adorable and that even when I'm close you can't ethically get me to stay away?”
“Me? A Fatui harbinger caring about what’s ethically sound?”
“I suppose that's counter-intuitive.”
“It is.”
The conversation lulls, but not uncomfortably, as for it follows the familiar nature of their banter.
“Well I do have something on my mind actually.” Columbina shifts her head to look down at the protruding apparatus ticking by as it rotates round and round and round.
Columbina's sudden silence infuriates the mechanic, “well what is it!? I'm not a mind reader!”
“Your key… how does it function exactly?”
Sandrone stills for a moment before responding lowly.
“It’s not going to stop again Columbina.”
“I believe you, I really do, but I still want to know…" Columbina's eyes haven't ripped away from Sandrone's back, burning the sight of perpetual motion to override its cold and stagnant memory. "I'm a curious blubberbeast after all.”
Sandrone thought about this for a moment before she decided to indulge Columbina.
“Ok fine, you really want to know? I'll tell you. If you get left behind by my jargon that's your fault! Simply, it's the main thing that keeps my existence going, like a heart for humans. Alain designed it using Arkhe energy, more specifically Pneumousia annihilation technology that powers my kinetic core. In order to keep it stable, the key turns in tandem to the forces being acted upon the core. However that's just one of its purposes since it’s been alleviated through other mechanical functions, as of now its main functions is actually heat regulation. This is due to it being connected to a cooling system. When my servos become over exerted my key will spin faster, when that is occurring my internal fans spin faster as well. I have other methods of regulation, such as breathe, coolant, and vents by my joints, but the key is most efficient by far. Moreover, the other functions my key covers are—”
Sandrone’s voice fades away in Columbina's mind as she thinks back to their time yesterday and remembers moments where her key was rotating faster than usual. It was whenever she was embarrassed, flustered or surprised, her key would stutter slightly before rotating faster. It was a newer development she insists was spurred from her accepting her ‘anomalies’ and Columbina has found herself happier witnessing the physical change in her dear Sandrone.
But at the same time, the key was also definitely whirring when her face was between Sandrone’s legs. She remembers a sharp whistling sound when Sandrone reached her peak that then quickly subsided. She hadn’t noticed it then but it seems so obvious that her over exertion also extends to sexual activities as well.
If Sandrone’s key would spin faster when she was sexually stimulated, would it be a stretch to say that the key itself is the indicator to arousal? If the key was forcefully acted upon would she become doubly aroused? If she abused the heating system to make Sandrone hotter than cooler, how good would she feel?
Columbina, while lost in her thoughts, cups one of Sandrone's breasts instead of her hair strand. Sandrone flinches at the contact and sears her circuit board.
“Are you insane!? Hands off, now!” Sandrone whirls around in her stool, putting down her soldering gun and swipes the board to the far side of the table. “Were you even listening to me!? What is the point of asking questions if you don't want to hear the answer?”
“Sorry Sandrone, I was just…” Columbina peters off, distractedly looking down at the obscured key, trying to sense if it's spinning faster. With her kuuvahki she senses hastened movement but she still wishes to witness it with her eyes too.
Sandrone misunderstands Columbina’s gaze and gives an almost soft look back to the moon goddess. “Can’t you wait a little longer before you bother me today, I know that lately we’ve been having quite a bit of,” she coughs into her hand as a show of faux politeness, “fun… but I of all people know you are more than capable of being patient for me.”
It was true. Ever since they reconciled, they have been inseparable in more ways than one, all in part by how much Columbina kept Sandrone in her heart despite not knowing if she would ever come back. Sandrone expected that Columbina would eventually ween off her due to how many nights and tea parties they have spent together. However Columbina, greedy as ever, remains seemingly unsatisfied.
Sandrone chooses to turn back around in her stool, attempting to get back to her work. Columbina, with a new chance to look at the key sees it and gauges that it either came back down to normal or stayed the same. She gravitates back to Sandrone, ever perceptive of the key protruding from her lower back and is back to rubbing her whole face on Sandrone's crown.
“Sandrone…” Columbina calls, tilting her head forward and shaking it to deliberately tickle Sandrone’s face with her own hair.
“Columbina,” Sandrone growls, lifting her hands to still the second sensory assault. She raises her head to meet Columbina's deep radiant eyes pouring into hers, with a stupid dopey smile adorning her face, “seriously, what is up with you?”
“Nothing much…”
Sandrone raises an unconvinced eyebrow. “Do you really want to be near me this much?” Another unfulfilled question that is filled with the slight twitch of purple iris'. “Sigh, come here.”
Sandrone gives up on staying productive with the disturbance called Columbina looming over her incessantly, and decides to get up from her desk and sit on the edge of her bed. She then pats her lap invitingly, looking at Columbina who has been watching her every movement. She figures Columbina would need a little physical affection before she would get any meaningful answers to her antsyness.
Columbina readily clambers onto her plump thighs, crossing her legs around Sandrone's behind, easily straddling Sandrone while resting her arms over Sandrone’s shoulders. Sandrone rests her hands on Columbina's lower back, securing their position.
They gaze into each other longingly, soaking in each other’s beauty before anything more happens. The first time they looked into each other's eyes they were stunlocked, unable to gauge that it was the first time they were gazing into each other properly.
“Is this better for you, Columbina?”
“Yes.”
“Honestly it's only been a couple hours…”
“I still miss you.”
“...I’m right here.”
Columbina then leans in impossibly close to Sandrone’s face and nuzzles her. Sandrone slightly flinches at the feathery contact but stills as she lets Columbina mark herself all over her.
“So… this is what you wanted huh? You’re insatiable...” Sandrone surmises. She can't believe she let herself be so easily wrapped up in the whims of this audacious Moon Goddess. She holds Columbina closer, in spite of her words, letting herself indulge in this feeling of being wanted all over again.
After a while of feather light brushes and serene murmuring, Sandrone directs her lips towards Columbina’s in an act of impatience. She feels Columbina’s breath dance upon their brushing lips and sees her eyes become heavy.
“Sandrone, can I?”
Sandrone really can't believe she let Columbina get her way but decides to be a bit more selfish in how they start.
“Please.”
Not a moment later Columbina dives into her and finally seals the two together. Their mouths instantly move in tandem as the sounds of the lips connecting and reconnecting fill the room.
Columbina's grip behind her gets stronger, as she starts tugging on her loose hair, shifting herself forward to grind their bodies together to strengthen the contact between them.
Columbina peels away from Sandrone's face and coaxes Sandrone head to her collar, the new angle allows Columbina to better look over Sandrone's back and to gaze at her key. Predictably, it's starting to spin quickly. Gently, she caresses her hands down from their grip behind Sandrone head, down to her exposed shoulder blades and flits across it, the sensation drawing a deep shudder from Sandrone as her mouth latches and sucks on to Columbina's lower neck for support.
“Ahhh, mmmm.” Columbina gasps, not expecting the stimulation.
“Your neck is still sensitive as ever dove.” Sandrone murmurs, as she raises her own hands to try and massage Columbina's wings, another erogenous zone. However Columbina pulls away from her grasp gently to shake her head.
“I want to take care of you right now, will you let me?” Columbina sees Sandrone pout from the corner of her eyes, as a quick apology she brings their faces back together to grant her another kiss, one she easily melts into.
They continue kissing while Columbina tentatively continues to dance across Sandrone's expansive back, slowly but surely reaching her goal.
As she reaches the top base of the key, she and Sandrone's lips finally part again. Sandrone looks up at Columbina, expectantly and lovingly before resting her head gently into Columbina's chest, her key spinning wilder than before.
Columbina understands this firmly now — Sandrone is starting to overheat and it's making her mouth water in delight. Her fascination with Sandrone doesn't stop with the key but with every other part of her masterful design. Her artificial skin radiating a wonderfully warm sensation as her coolant rushes to get her back to operational temperatures, her breathe becoming marred with a crisp routine huff, the visible puppet joints exuding a low whir of their own as air inside her vents blow past. All tucked away within a gorgeous body Columbina would spend years worshipping, she almost feels unworthy of getting to indulge in such an sensation. She never had the fortune of ever meeting Sir Alain Guillotin, but she can tell by his meticulousness that he loved Sandrone so much, and she is ready to also provide her with the love she deserves as well.
Columbina puts her hypothesis in action as she starts to paw gently at Sandrone's key, letting her bashed hands be the slight point of resistance, gauging whether or not a foreign feeling of her key being forcefully acted upon would cause an inverse effect. Backing up her heat to be expunged all at once so she's technically cooled but her body continues warming up.
"Columbin- haaaaa, what are you doing to my key?" Sandrone grunts out, arching her back into Columbina and burying her face deeper into Columbina's chest. Already, Columbina receives positive feedback so she increases the resistance. She attempts to tries to grab the key and notices it's fortunately not hard to do, as if it were designed to not snap off in case of potential obstructions.
"You're so tense Sandrone," Columbina whispers back to her, pressing a soothing kiss to her crown yet again, "relax for me dear."
"But you keep fiddling with my key, how am I supposed to relax! Haahh, stop teasing and just go down on me already." Sandrone whines back, trying to grab Columbina's arms around her waist to pull them away from their adventures across her back, but Columbina snaps back at her defiance by gently nipping Sandrone's red ear.
"You promised me it wont stop again." Columbina gives Sandrone a lick afterwards, earning her a pleased sigh. At the next moment she daringly halts Sandrone's key for a brief moment before slinging it clockwise. Sandrone head shoots up from her perched position and releases a choked moan, her arms becoming stiff for a moment.
"Ahh haaa, ahh Columbinaa!" Sandrone moans, not expecting such a fierce sensation to rapture her completely still for a moment and Columbina is mesmerised. Proof of her infatuation is behind her soaked panties but she ignores it to continue chasing her theory.
"Sandrone, you're so alluring to me, you drive me crazy."
"Gods you drive me crazy too... why are you tinkering with my clockwork key when I have installed a perfectly functional reproductive organ? Did I make a mistake going out of my way for you?” Sandrone tries to bite out harshly but it forms itself as a whine. Her breathes evolve from puffs to clouds as the emerging quake of heat pooling at her lower back screams for more ventilation.
"You didn’t make a mistake, I love it very much, you taste so good." Columbina starts, giving Sandrone a light kiss on her temple. "However, I just want to do it more... 'naturally' this time."
Sandrone couldn't help but wince when Columbina suddenly grabs her key and halts it for a split second before pushing at it again but faster. Somehow, maybe because it is the second time she's done this, she has become looser and more relaxed to Columbina's unnatural method of affection.
Sandrone's head rolls back again as she moans loudly. Sandrone leans back still resting upwards on her arms as she tries to recover and Columbina chases her down. Columbina gets up from sitting directly on Sandrone's thighs to position herself more freely. While resting on her wide set knees, she takes an opportunity to attach herself to Sandrone's exposed throat and to suck and nip on her skin so deeply she can feel the wiring get pulled into her mouth. Sandrone's voice shoots up an octave and her tongue pathetically lulls out her mouth.
"So this was your goal for all your annoyingness earlier huh? You just haaah, like fetishising me, don't you?" Sandrone heaves, her breasts moving up and down, forcibly trapped by the constraints of her dress. Considerate Columbina's lips travel lower and lower, kissing sucking biting, and starts pulling down her dress, inducing more moans and squirming from the hapless automaton beneath her. “You just like what makes me tick, it's why you mppghhh, it's why you like pushing and prodding me to my absolute limit ah—ahh!” Columbina's lips fully surround Sandrone's nipples as she collects both breasts to suckle while caressing her immodest swell. Her complaints devolving into sighs and gasps as Columbina's ministrations get stronger and needier.
Columbina momentarily stops her attack to lean back and give Sandrone a very shameless look. Her upper body is flush with pulsating red coolant and recent bites and bruises decorate her artificial skin.
"Yes, I don't just like, but I love every aspect of you Sandrone," Columbina admits so full of adoration and joy Sandrone couldn't help but look away. But Columbina leans back in to press another chaste kiss on her breast before continuing. "I do mean every," Columbina presses for a kiss on Sandrone's limbed puppet joints, "last" she rises, capturing Sandrone's jaw, "aspect." She finally closes in and kisses Sandrone full mouthed as one hand steadies her balance on Sandrone's shoulder and the other harshly presses on Sandrone's key, again, and again. Sandrone spasms at this overload of senses, her ventilation being used inappropriately and her back up, her mouth, being senselessly ravaged by her moon goddess. She can simply roll her eyes back and submit to the her overclocking pleasure.
“You say that I'm patient Sandrone but that's not the truth, not even close." Columbina confesses, drunk off the heat that her beloved puppet is enveloping her in. She rubs, she kisses, she mouths, anything to get as close as possible to Sandrone. "I yearn for you with each waking moment, I need you Sandrone, you complete me. From the moment you brought me back from the moon's reflection I became yours. I missed— I miss you so much. Do you feel the same way dear Sandrone? Don't you want to want to become mine as well? Can I say that Sandrone is mine?" Columbina looks back properly at Sandrone and notices pleasure streaked tears running down her face, she stops touching her key or kissing her face to instead deliriously lick them off for her.
Sandrone comes to a moment later, her eyes glazed and her voice hoarse, she looks back at Columbina's pleading expression and smiles “...Of course I'd want you too, idiot.”
“Sandrone...” And with that Columbina immediately lowers her lower body to make contact with Sandrone's own neglected core, rubbing her own damp panty against Sandrone's. Sandrone's legs unconsciously part open, allowing Columbina more space to raise one of Sandrone's legs for better friction between her and Sandrone's cores. Their dress rolls up higher and bunches at their waist which lets them have more space for rocking. “Just watching you, ngh, becoming undone by me, haaah, has gotten me so close.”
They grind desperately knowing the other is tantalisingly close. Sandrone body, seemingly incapable of doing anything except be submerged in this overwhelming pleasure. Columbina in the midst of euphoria, fully hugs Sandrone, squishing her chest with Sandrone's wildly bouncing breasts and worms one of her hands towards Sandrone's back, frantically pawing at Sandrone's key. The resistance causes Sandrone to jolt violently.
"Wait! It's too much, nghaa—"
"Haaa, haa, together with me, Sandrone!"
The heat becomes too much for her system to keep up, too overstimulating, too overwhelming. So something she never knew her body could do happens to Sandrone. Her breathe bellows a huge blanket of smoke and her servos produce a sizzling popping sound, she screams as ejects a large bout of steam alongside dispelling jets of slick between her legs. Columbina similarly came as well, covering their already soaked undergarments and bunched up dresses with her own essence.
Columbina nestles close to Sandrone in the afterglow, ignoring the drenched bed and their ruined clothes underneath them.
"Ahh haa, I'm assuming you enjoyed that Sandrone," she chuckles to herself, looking back up at Sandrone who has remains motionless. Quickly, she panics, grasping Sandrone's face to meet her properly. But just at then, her gear eyes tick once more and Columbina sighs in relief.
"…I just had to do a soft reboot."
"I thought I pushed you too far."
"You absolutely did, honesty only you would be so curious as to abuse my key for freaky nonsense." Columbina softly laughs at her light chastising and gives her a very familiar apology kiss.
"I'm sorry Sandrone, for a moment I—"
"Shh, I understood when I saw your face. Your annoying, round blubberbeast curious face that something bad had happened to me, but regrettably it's… the opposite." Sandrone whispers embarrassingly.
"What was that?"
"Ugh how can you go from acting so cute and docile to this annoying creature in an instant! I'm not saying it again!" Even after her natural processors have gone back to their non hijacked job, her body still feels as hot as pre-climax.
"Hehe, we should do that again sometime."
"Is sex the only thing on your mind? Get off, lets clean up and don't disturb me for the next 24 hours." Columbina obliges and they get cleaned up. But her gaze remains to that now stable ticking key on Sandrone's back. As it ticks away she hums to herself in tandem, surely a little sound isn't disturbing? But she knows Sandrone is still keenly aware of her, watching her back to work and that she herself can't help but stay tethered to her doll. She smiles, Sandrone is hers and she is Sandrone's.
