Work Text:
“Nines? I’m making a small pot of that coffee you bought earlier. Do you want a cup?”
2B voices the question, only for it to uncharacteristically be met with silence. Even the gentle sounds of metal tools clinking against more metal as 9S tinkers with yet another scrap-work project upon the table has quieted considerably.
She turns her gaze away from the small kettle then to look over at him, the small machine part still resting partially in his hand while he absentmindedly twists at one of its bolts with a screwdriver. All the while his eyes remain glued to the rather large, rectangular, metal storage container that lies propped up against the wall on the other side of the room.
2B knows what’s in that container. It’s the… ‘spare’ custom YoRHa model that 9S had whipped up as a sudden surprise a few weeks ago. She vividly remembers the sight of the alternate body. The rather significant height difference, as well as the somewhat sharper features that had been adjusted into its design by none other than 9S himself. It was meant to resemble one of the previously manufactured male models used back in the early days of YoRHa, based entirely off of a decade’s old blueprint of a D-type. 9S had opted to ‘test it out’ both in and outside of the battlefield, getting a genuine feel for its features and advantages—and admittedly, the new body was nothing short of attractive, so much to the point that 2B could barely even look at the other android without feeling a rush of…certain feelings.
However, 2B couldn’t get past the fact that it simply felt too… unfamiliar.
Obviously, it was 9S, and yet it… wasn’t all at the same time.
The sudden differences honestly made it difficult for her to even accept simple shows of physical affection from him.
When she had come clean about this, 9S simply listened, smiled, and ran to change back into his normal body, tucking the newer one away in a tightly secured storage container for spare models.
2B had made a point of telling him that he could still use it, just that it needs some getting used to on her end, and 9S had happily agreed with the request.
However, since then…it hasn’t even been touched…
When he still doesn’t respond, 2B steps closer to him, leaning over to peak between her distracted partner and his work.
“…Nines—”
9S jolts to attention at the slightly louder call of his nickname, immediately turning back to look between 2B and his work upon the kitchen table.
“Oh! Sorry, I uh…zoned out for a second there…” he says with an almost guilty sounding tone, as if he’d just been caught in some sort of act. “Coffee would be amazing, 2B, thank you!”
He says the last part with a smile and more sincerity this time, but 2B can’t help but still feel a bit… bothered by his initial reaction.
This isn’t the first time she’s caught him staring at that storage container either. The way he occasionally glances over at it, practically able to hear the literal gears turning within his head in thought.
She can’t help but wonder if maybe, just maybe…he’s hesitant to use it out of worry for her comfort.
The thought admittedly makes her feel a little bad. He did seem pretty excited about having a new, custom built body…and yet, since then, he hasn’t even mentioned it again.
“….”
“2B? What on earth are you doing?”
2B glances over to see 9S paused at the doorway as she fiddles with the latches along the storage container, quickly standing up to gesture to the now unlocked box containing the spare model.
“You’ve been wanting to try out your other body again, right? I think now would be a good time.”
9S’s eyes widen in surprise, appearing to be taken aback by the sudden suggestion.
“What’s this all of the sudden..? I didn’t think you wanted me to use it—not so soon , at least.”
“Well. I’ve been thinking…”
2B glances down at the steel box, gripping the fabric along her gloves a bit restlessly as she gathers her thoughts.
“…About what you said regarding spare bodies. With the bunker being long gone, along with access to almost unlimited copies of our exact models, it leaves us with whatever we have now. I started thinking about how, if something were to ever happen to your current body…you’d have no choice but to transfer your data to this one. So…”
9S frowns slightly.
“Aw, 2B…”
“I did say that I could probably get used to it over time, so… with that in mind, maybe it would be best for me to… go ahead and try.”
He approaches her then, his gaze sympathetic as he reaches down to carefully take one of her hands between his in a comforting gesture.
“I mean, I don’t want you to feel pressured into it though if you’re not comfortable with it…”
She shakes her head. “I don’t feel pressured. I want to get better used to it. I do. I just…don’t really know how exactly.”
9S pauses, putting a hand up to his chin as he thinks carefully on her words.
After a long moment, he eventually speaks up.
“…What if I switched over to it for a short while and let you… ’play around’ with it, basically?”
2B’s serious expression drops for a second to cock a brow at him.
“N-Not like THAT! That’s not what I was getting at—Or well, I mean, unless you want to—”
“Nines.”
“Gah! Okay, what I mean is familiarizing yourself with it, essentially.”
“…Familiarize myself..?”
“Yeah, you know, like…Examine it. Touch it. Poke it. Look at it. Listen to me speak—do whatever you need to. Just take a good, long, moment to really look at me.”
That…sounds a bit odd, honestly.
But, thinking about it…that might be the best way for her to get herself used to seeing and feeling it.
Hearing his words, 2B eventually raises her head to slowly look back up at him, and nods.
“…Alright. We can try.”
9S smiles, leaning over to plant a quick kiss to her cheek before stepping over to where the storage container lies.
“Great! Just gimme ooone second to change over…”
After allowing 9S a few much needed moments to transfer over his consciousness and properly calibrate the secondary body, the two of them soon find themselves seated upon the couch beside one another, with 9S positioned close enough, yet at a respectable distance.
Meanwhile, 2B’s eyes proceed to drag up and down the…abnormally longer expanse of his body. From the lengthier legs that actually manage to touch the floor from where they’re sitting, to his slightly broader shoulders, all the way up to the pair of familiar blue eyes that stare down at her.
She knows full well that this exercise is meant to help her grow more accustomed to his second body, and yet…The more she stares, the more… off it all feels.
She can feel her nerves beginning to twist with that same offputting feeling as they did before, until she feels the gentle sensation of fingertips grazing the top of her thigh.
Not too sudden.
Not too much.
“2B?”
2B looks up at him then to find one of the more definite, familiar traits of this new form: his face. More specifically, the pair of exceptionally soft and ample lips that are part of it. The latter of which is pulled upwards into that same exact, warm smile she’s found herself hopelessly drawn to ever since she first met him.
…Only it’s also now accentuated by that slightly sharper jawline.
A sight that causes her cheeks to heat up and her black box to whir just slightly more than they already were to begin with.
“Are you okay?”
That is a very good question, she thinks.
One she’s not entirely sure how to answer.
“…I’m not sure how to go about this, exactly.”
“Start wherever you want,” he says in that reassuring tone he always uses. “Don’t just focus on the differences or how my body is unfamiliar, instead, look for what is familiar, and go from there. Just focus on the parts you actually know as me .”
2B pauses for a long moment, taking her partner’s words into genuine consideration as she continues to stare at his smiling face.
“Just go at your own pace and take as long as you need, alright?”
“…..”
Eventually, she lifts her hands up to his face, cupping either side of his cheeks between her hands as she dents her fingers into his smooth skin.
“Okay, okay, that’s a start,” he says with a small giggle as her hands soon begin to move more.
She takes a moment to genuinely examine his facial features, her fingers denting slightly into the sides of his face as they push against and shift and pull somewhat at his cheeks. It’s definitely 9S’s face alright. Despite the somewhat sharper jawline, it’s still quite evident now that she really looks at it. The icy-blue eyes that continue to stare back at her with a gaze so soft and benign. The gentle warmth of his increasingly blushing cheeks that radiates beneath her palms. The way those gorgeous lips remain kept in the form of an optimistic smile.
The more 2B stares and feels at it, the more familiar it becomes.
Just like he said.
“So, I take it you’re enjoying yourse—”
His words are cut off a bit when 2B suddenly squishes his cheeks together in a way that puckers his lips somewhat. The sight causes her to huff out a small laugh, releasing her grip on his face altogether. The moment she lets go, his smile returns in full, seeming to be utterly amused by the way her own curious side peaked out just then.
“Alright, now where to next?”
With the tension slightly dissipated and 2B now somewhat more confident, she decides to drag her touch down to the side of his neck, her fingertips brushing gently against the familiar feeling of warm skin as they slowly make their way down to his collarbone. Eventually, her fingers drag even further down to splay over his clothed chest, pressing her palms against the slightly broader torso and feeling the way his chest rises up and down with every minuscule breath.
…However, the distinct lack of a black box vibrating just ever so slightly beneath her touch does not go unnoticed, and 2B can’t help but frown slightly at this.
9S must have immediately caught onto this reaction, as his hands then slowly lift up to fold gently over hers.
“Unfortunately, the lack of a black box can’t really be helped. This body is powered with different methods.”
That’s disappointing, but understandable. After all, recreating a black box would have to be quite a difficult, perhaps even impossible process, she imagines.
“ But, I definitely can see about adding a makeshift heartbeat to this backup body. If that’ll make you happy.”
2B smiles at that, the sweet, endearing words being spoken in his voice doing well to help calm her heart.
With that, 2B then decides to take her examination outwards a bit. Her touch soon drags back over to his shoulders, sliding her fingers down the length of his arms and wrapping carefully around them, offering them a light squeeze . It’s not a drastic difference at all, per say, but the distinct addition of more musculature is very much noticeable. She supposes that makes sense though, when she thinks about it. After all, supposedly this particular model was based off of a D-type combat unit. A slightly wider frame and appendages is sort of a given.
The more she slides her hands up and down his arms, however, feeling at the rather lean contours beneath her palms, the less… weird it feels.
Honestly, she’s just glad that 9S didn’t go with one of those more… buff models from early YoRHa.
She likely wouldn’t have been able to cope with that.
“You doing okay, 2B?” he asks once again.
“Mhm…” she mutters with a nod, her gaze focused intently on his midsection now.
Okay…
So far, this…isn’t too bad.
Dare she say, she might even be starting to enjoy it in a way.
Growing more comfortable and confident with each touch, 2B scoots even closer to him to get a better look, her thigh now pressed up against his as she proceeds to run her hands up and down his sides next.
“Aha—!”
2B startles at the sudden sound, only for 9S to immediately wave it off with a smile.
“S-Sorry. I’m still sort of…ticklish there,” he says with a small chuckle. “That particular part from my old body somehow managed to transfer over to this one, I guess. Weird, huh?”
The sound of his voice is doing wonders in calming her nerves, each word that leaves his gorgeous lips serving as a gentle, yet firm reminder that this is 9S. No one else. It’s him.
Especially when he graces her with that same airy laugh of his that always manages to make her lips stretch into a smile and her heart skip a beat.
This body may obviously be different in many ways from his original…but, she’s finally beginning to view it as some sort of… extension of him. In a way. Something different, but very much him.
2B’s hands travel downwards more and more as she carefully explores the new body at her personal leisure. Her fingers slide lower and lower… now feeling lightly at the area around his upper hips.
“Hey, 2B?”
Heat begins to rise in her cheeks as her eyes drag up along the expanse of 9S’s current body, eventually stopping to meet his gaze.
She studies his face once again, finding that this time, it’s accompanied by a noticeable blush dusting his cheeks and that soft, half-lidded gaze.
…As well as that ever familiar smirk as he stares down at her.
Uh oh.
“You know,”
Another, very slight difference that 2B can’t help but notice—especially now , is the way that his voice seemed to have gotten just ever so slightly deeper in pitch. It’s not a huge difference at all…however, it definitely only serves to add onto the… other feeling that currently floods over 2B’s person. The same feeling that’s been constantly increasing the more she’s been made to ogle and fondle her partner’s brand new physique.
“I did mention that I added a few… upgrades to this body. Ones that I think you might take to rather well, 2B.”
That last part is accompanied by a cheeky little wink, a move that almost makes 2B want to punch him in the side for causing her face to redden even more.
However, that’s not the worst of it.
The worst of it, is when 9S slowly begins to lean into her, the distance between their faces gradually decreasing with every inch he crosses.
“What’s wrong, 2B?” He speaks with a purr in his voice, one that 2B is finding it harder and harder to resist with every passing second that she’s forced to hear it.
Not to mention; the way he’s definitely uttering her name with a dragged out, borderline groan every time on purpose.
“…I think you know what.”
“Do I? I don’t believe I do, sorry. Why don’t you take a moment to show me…”
9S leans down then, lowering his voice an octave as he gently presses his lips against the side of her ear and whispers.
“… 2B.”
A powerful shudder erupts from 2B right then and there, her own lips just slightly parted as her breathing and internal temperatures begin to increase immediately after that.
In the next moment, her hands fly down to shove the lower parts of his coat out of the way, her fingers fiddling with the zipper along his pants before sliding up to tug at the hem of the leather garments. 2B doesn’t even need 9S to tell her what to do next; her hands slowly glide their way back up to dip beneath the waistband of his boxers as she carefully pulls them down and over his thighs. They easily slip out of the way, and once they do, 2B feels her breath catch in her throat as her eyes widen at the…rather generous upgrade that 9S apparently opted to give himself.
2B just simply stares at the sight before her, her eyes momentarily glancing up to meet 9S’s cocky little grin, before darting back down.
“Well? You like what you see?”
“It’s…”
The blush upon her cheeks merely darkens the more she gawks at it.
“…How will that even fit?”
The sudden chuckle that leaves him in response to her genuine question causes her to pout somewhat.
“Don’t worry, I did the math and research and made sure to pick a size you’d be able to handle.”
2B doesn’t even want to ask him to elaborate on what in the world that means.
“T-That is, of course—I mean…. If you want to…do something like that. With this body. It’s okay if you don’t!”
When 2B eventually manages to pry her dumbfounded stare away from his lower-half, her eyes drift back up to once again to look at his face—the easily most familiar and recognizable part of this new body for her. The sight of those brilliant, bright eyes full of so much care and expression that stares back at her with equal amounts of want, yet patience. 9S is simply eager to please her, clearly. .
“Listen, 2B. I want nothing more than for you to be able to enjoy this as much as I can. I wouldn’t dare pressure you into going through with something like that unless you were one hundred percent comfortable with it. After all, I designed some of these features entirely with you and your own satisfaction in mind, so if you aren’t sure about it, then seriously, please, don’t worry about it,” he says with as soft and reassuring a tone as he can muster. “There is nothing that’s more important to me than your comfort and happiness.”
2B hangs onto every single word that leaves his mouth, her gaze focused intently on the way his lips move to convey each one.
Those soft, ample, lightly hued lips…
A pair of lips that she’s certain would feel so divine against her skin if he were to just…
Suddenly, without so much as a word, 2B lifts her hands up to caress either side of his face. Her thumbs take a moment to press lightly against the skin of his cheek, eventually sliding over to brush one along his bottom lip in a slow, delicate, appreciative manner.
“2B…?”
In the next moment, 2B is hooking her fingers around his jaw to carefully pull him closer, guiding him downwards until those lips meet her own in a chaste, gentle embrace.
Her eyes remain open the entire time. Not out of lack of enjoyment or anything like that—quite the opposite. It’s so she can continue to gaze at his own eyes—at him.
A good, gentle reminder that this is no stranger.
Before she knows it, 2B is deepening the kiss ever so gradually, choosing to move her lips against her partner’s while he simply stares directly back at her with that desireful, half-lidded gaze.
Her hands slide down his face then to brace against his chest, moving to once again feel at his arms as she continues to kiss him with direct eye contact. He is fully and intentionally allowing her to take the reins, guiding both of their movements as she explores his body at her own pace. Familiarizing herself, just as he had suggested… and finding that it’s beginning to work .
At one point however, 9S carefully pulls away just slightly until he’s a mere few inches from her face, much to 2B’s confusion.
“I have an idea I think you might like, if you’ll allow me.”
2B isn’t quite sure what exactly it is he has in mind, but if it’s 9S making the suggestion, she trusts him.
The moment she offers him an approving nod, he smiles, leaning back in to press a quick kiss to her lips before shimmying himself off of the couch entirely.
2B is bewildered by his sudden movements, until she observes the way he gets on his knees before her, removing his gloves before sliding his hands beneath her knees and gingerly lifting her legs up to drape over his broad shoulders. He then lifts a single hand up to reach for the string that ties her skirt together at her hip, pinching it between his fingers and slowly pulling it apart. She stares with a shaky breath as the black skirt loosens around her waist considerably, before being pulled away from her altogether and tossed elsewhere.
With that, 9S then leans closer to her, hooking a single finger around the already damp fabric that covers her pussy and pulling it to the side. His eyes remain trained on her face the entire time he does this, even as he leans in to press a single, loving kiss against her folds. 2B’s legs jolt slightly at this, having been already immensely pent up from the way she had been practically fondling him prior to this.
However, it’s when 9S’s lips pull upwards into a little smirk against her pussy does she feel her knees grow weak.
Taking note of her reaction, he keeps going. He presses a few more sweet kisses against her cunt, trailing upwards to brush his lips against her clit in a way that nearly drives her insane. She then watches as he drags the flat of his tongue across folds, slowly repeating the same action again and again, before finally slipping inside. All the while he stares up at her, refusing to break eye contact even once.
2B feels herself sink back against the couch as he does all of this, her legs instinctively moving to wrap around his shoulders and hold him even closer.
She does her best to maintain eye contact, focusing on that familiar gaze of blue as he continues to practically devour her. Although, that’s a bit easier said than done when he’s doing the latter a little too well. 2B can’t help but squirm and writhe somewhat against the couch as waves of wanton pleasure invade her very core, trying her best not to crush his face between her thighs as they continuously open and close with every thrust of his tongue.
“Nines…” she groans, her hand flying down to thread her fingers between his pale blonde locks. Even as she tugs at his hair, he still doesn’t break his gaze. “Please…I n-need you so bad…”
Apparently that was all she needed to ask, as suddenly 9S is now pulling away and looking up at her with a smile, his lips and chin slightly wet from their little activity just now. He finally breaks the eye contact for a brief moment, however, as he reaches behind him for the small bottle on the coffee table, uncapping the lid and pouring a bit of lube into his palms as he stands up to take his seat on the couch next to her again.
Ah. Right.
With a fairly significant size difference being at play here, it would likely be best to prepare as much as possible.
Or at least, as much as their growing impatience will allow them.
“Wait,” 2B says, suddenly stopping him. “…I want to do that.”
9S blinks for a moment, before offering her yet another sweet smile as he removes his hand from his cock completely. “Be my guest.”
Normally, 2B would’ve simply just allowed her impatience to get the better of her and let him finish the lubricating process as quickly as possible. However, given the circumstance, she figures it might be better if she takes a moment to actually familiarize herself with these new, altered parts of his body.
With that, 2B carefully wraps her fingers around the base of his already partially slickened cock, moving her hand up and down in an attempt to thoroughly coat his length. She feels her mouth go dry the more she continues, feeling the noticeable differences in full as she has to put in a little more work in fully coating his dick than usual. But, nonetheless she takes her time, learning and familiarizing herself with each and every single minute detail. She hears 9S gasp somewhat as she slides her thumb up and over his tip, increasing her pace as she coats it all as thoroughly and effectively as possible.
Once that’s done, 2B slowly pulls her hand away. She doesn’t waste a single second more as she then sits up to throw one leg over his hips while bracing a hand against his chest for balance, positioning herself until she’s straddling either side of his lap.
9S’s hands slide up along her thighs to settle at her hips. Even his grip is just a little bit stronger than usual. Especially with the way his slightly larger hands are able to wrap around her a bit more than before.
However, she quickly lifts her gaze up to his face once again, choosing to focus on his eyes and lips and expression. Just like she did before.
“Are you ready, 2B?”
“Yes..” She nods, biting her lip as she spreads her legs apart just a bit more.
She takes a moment to angle the tip against her entrance, feeling him slip past her folds, before slowly … carefully …sinking herself down onto him.
“O-Oh..god..”
2B takes her time with the process, as does 9S as he takes great care to make sure she’s comfortable. It’s definitely a noticeable increase compared to his other body, not just in length, but slightly in overall girth as well. Inch by inch, 2B slowly feels more and more of him slip past her folds, the increasing feeling of fullness causing small groans and short hitches in breath to leave her. Occasionally, she stops, lifting herself up somewhat before lowering herself back down again. She repeats this process many times, taking him in just a few centimeters at a time as she carefully adjusts herself to his length.
“You’re doing so good, 2B…” the sound of 9S muttering words of praise directly into her ear only serves to further build onto her intense arousal, making the process slightly easier, even. “You’re a little over halfway now.”
Suddenly, her grip on his shoulders tightens in a way that almost hurts him.
“ H-Halfway? ” she whispers in a hoarse voice.
2B feels like she’s going to self-destruct just from what she’s managed to take in so far. Exactly how much of an ‘upgrade’ did he give himself..? Nevertheless, She continues to carefully ride up and down the length of his dick, gradually lowering herself onto him more and more with every meaningful movement of her hips. All the while shaky, breathless moans leave her parted lips.
Eventually, after what feels like forever, 2B finally manages to take all of him—feeling herself sink down fully onto his base as 9S damn nearly bottoms out inside of her. It takes her a good second to gather her composure, allowing herself just a moment to revel in the intensely full sensation and to get used to it.
Before long, her arms come up to wrap around 9S’s neck as she soon begins to move again, lifting herself up carefully, before lowering back down again. Repeating this same rhythm over and over again as she slowly grows used to the size. The distinct mixture of bland pain mixed with an increasing pleasure practically rocks her to her core, unable to help herself as she soon finds herself bouncing atop his cock at a steadily rising pace.
Meanwhile, 9S just simply watches with a lust-induced gaze at the personal show being put on before him, in his very own lap. The way 2B doesn’t dare cease her movements as she continues to ride him with a rapidly increasing fervor. The way she momentarily throws her head back in pleasure, only to quickly snap herself back in place just to focus her half-lidded gaze upon him.
“Nines…”
His name falls from her lips like a nearly serenaded prayer, staring back at him with a look of ceaseless want.
“2B..”
Slowly, one of 2B’s hands slide around to gently caress the side of his neck, an action that causes 9S’s breath to catch in his throat for a moment as a deep moan slips from his parted lips.
“… Nines..”
Right then and there, 9S suddenly tenses up and his grip on her hips tightens to the point of inevitable bruising.
“Fuck—”
Just like that, his patience snaps like a twig. In the next moment, 2B feels his hands slide underneath her legs to grip either side of her ass, suddenly finding herself being lifted off of the couch entirely—her arms having to quickly cradle around his neck even tighter just to avoid falling while her legs haphazardly wrap around his hips. 9S straightens himself as he stands, hastily readjusting his hold on his partner as he hoists her up into his arms. Then, in a surprising show of newfound strength, 2B feels herself being lifted straight up, and dropped back down onto his cock.
“A -AAH—!!”
A high pitched moan crossed with a scream immediately rips from 2B’s throat right then and there, any thoughts or words within her mind instantly being hazed over by an intensely dizzying pleasure as 9S procedes to fuck her mid-air. She can feel her thighs begin to quiver uncontrollably as she struggles to keep her ankles locked together, unable to even form a decently coherent thought or response as she’s repeatedly lifted up and down onto the entirety of his length. He’s taking full advantage of the changes in his body to do this, the height factor especially as he bucks his hips upwards to meet each and every single drop of her onto his dick.
Soon, however, 9S finds his ability to balance both of them slipping somewhat. Barely even thinking, he quickly stumbles over to the nearest wall—knocking a few things over in the process as he props 2B up against it, tightly grip the thighs still wrapped weakly around his hips, and fucks into her at a rapid, borderline animalistic pace.
2B is instantly reduced to a mess of warbled speech and shameless moans within his arms, all as she’s fucked harshly against the wall. The sensation being so intense and mind-numbingly pleasurable that tears begin to prick at and fall from the corners of her eyes. The hands cradling his neck claw and scratch at his upper back, the leather coat being the sole thing that prevents her from seriously damaging his artificial skin as she does this. The heels of her boots, even with her legs’ weakened hold on his middle, dig into his lower back. All in some kind of desperate, instinctive effort to be closer to him.
“N..N-Nin..Nine.. s …”
“2-2B…! F-F uck —!!”
With one final, powerful thrust, 9S at last hits his edge, as does 2B…pressing his body snugly against hers as he weakly attempts to hold her up while they both ride out their highs together.
Eventually, after a long moment, 9S hugs his arms around her lower-half and carries her over to the bed, delicately laying her very much exhausted body down onto the plush mattress.
“Hah..Well, 2B?” the scanner says with a tired smile as he looks down at her. “What do you think of this body now? Think you’ve gotten used to it a little?”
However, when 2B doesn’t respond, and instead merely continues to lay there with a dizzied expression, he frowns a bit.
“…2B?”
“Alert:”
9S startles a bit at the sound of Pod 042 suddenly chiming in.
“Unit 2B’s NFCS system has experienced a mild short circuit from overexertion of mental hardware. Proposal: Initiate maintenance.”
9S sputters.
“H-HUH—?!”
