Critical startup checks completed, and K came online, groggily drifting into consciousness. Further data readouts flooded her vision as additional subsystems were spun up, before fading away as her eyelids opened with a whir. A few moments of iris and camera adjustment later, she had vision, for all the good it did her with the gray steel door of the charging pod two inches from her face.
Her sense of touch came online next, sending shivers down her spine and a small exhale out of her mouth as she remembered the state she had gone to sleep in. It seemed the rest and recalibration had only done her so much good; tingles ran through her, and a little wetness issued forth from her synthetic pussy to stain her uniform.
Well, nothing to do about that now. She tried to take her mind off of her arousal, pulling the charging pod release once her motor function came online and feeling the slight whoosh of air as the thing opened.
She stepped forward, getting used to her legs once again briefly before clambering up the short ladder from the bunkered alcove the pod was in to the floor level.
Motorized doors opened for her to pass as she remote-interfaced with their controls. She proceeded through the hallway for a few moments before encountering quite a sight.
Her sister (another AZH-7 replicant using a neural pattern originated from whoever their human donor A.M.H.211 was, that is - specifically Branch38 'M') stood leaning into the gap created by an open wall panel, doing some sort of maintenance work on the equipment behind. However, M's uniform jumpsuit was halfway off, the upper half tied around her waist - exposing an elegant but strong form of synth-skin and carbon-steel. K felt herself cream a little more at the sight; she was long since past the point where she found anything weird about being attracted to a body identical to her own.
"Fuck, sis," she spoke breathily, catching M's attention.
"Well good to see you up," M replied. Something in her tone told K she knew the effect she was having, was deliberately playing coy. "Hand me the 8mm wrench there, would you?
"Mmn" was K's only response. She got the tool M was gesturing to, quivering a little as she got closer in to hand it to her.
"Not feeling talkative today?" M asked.
"You-" K stammered. "You know what you did to me last night, big sis. What you're doing to me right now."
"What's that, little sis?" M replied, infuriatingly playing dumb.
K groaned. "You fucking edged me, left me without release, and now your jumpsuit..."
"Ah, yes, I did do that," M spoke smugly. It was clear K could only lose, like every time her big sister got like this. "Can't a gal expose her heatsinks when she's doing hot-and-heavy manual labor, though?"
Unless... "You're impossible," K spoke. "I'll leave you to your work and take care of myself, if you're gonna be like that," she threatened.
M set down the tools she was using - and was on K in a flash. She held her sister to the wall, kissing her for a few long moments, then slid to her side to whisper in her ear, "you know the rules. You know you're not allowed." K just squirmed.
M ran a hand along K's body, brushing over her breast, making her shiver a little from the sensation.
"Please, big sis! I need it!" K whined, internally cringing at her own pathetic behavior, feeling further coils of desire shoot through her in response. Perhaps M felt the mirror-image of such sensation, or perhaps she simply wanted to shut her sister up, because she reached her other hand up and pressed a couple fingers into K's mouth. Before she could think, K was sucking on them.
The younger sister tried to push away from the wall, to buck her hips, anything for more stimulation. But she wouldn't be getting anything until M let her have it.
Fortunately, M pulled down K's jumpsuit, apparently bored with teasing her hands-off. She popped the release points for the carbon-fiber panel on K's groin, gasping slightly at the sight of her sister exposed before composing herself. "Guess you weren't lying. You really are wet," she noted.
She slid her synth-saliva-slickened fingers out of K's mouth, then ran them over her clit. K moaned, feeling warmth flush through her despite her new lack of clothing, twitching slightly and whirring as a coolant system kicked into gear inside her. She wanted this, wanted to be held to the wall helpless, touched however M chose, all of it.
K felt herself getting close to the edge, all the unrelieved buildup of the night prior coming right back to her. She moaned, "Please, please, ahn- fuck, right there," and luckily for her M redoubled her efforts, stroking faster, harder. "Cumming! Ohhhhhh," she gasped, falling apart in warmth and pleasure. Her hips pressed harder into M's hand, and a messy jet of cum squirted from her quivering hole.
When K came back to herself, her biocomponents felt warm and soft, like the fuzziness inside her brain. She mumbled a few syllables of nonsense, before feeling M's lips pressed against her own once more. She was just beginning to melt into the feeling of the kiss when it ended.
"What do you say?" M asked, a little forceful.
"Thank you..." K replied unsteadily, only to whine wordlessly as she received a pinch to her nipple, her eyes flicking open from the pain.
"Let's try that again," M pressed.
K took a slight moment, not too long, to muster more confidence in her voice, then said, "Thank you, big sis." She felt the tingling brush of M's fingers against her stomach again, until...
"There," M spoke, and sank those very fingers right into K's pussy. K moaned, somehow feeling herself melt into even more of a puddle than she already had been. Slickness began to run down her legs as M pleasured her; M noticed and teased "messy girl." A certain tremor in her voice betrayed a hint that her controlled front might be cracking.
"Yuh-you always know, how to get me wworked up, sis," K replied, unsteady in her speech once more. "Keep going, p-please?"
M gasped, shivered. "Of course... You're just too fun to play with, lil sis." She was clearly aroused at this point, laughing desiriously, "Hahahahaha... your cunt belongs to me, mmmn, mhm you're mine, my perfect submissive sister."
K whimpered, the synth-flesh of her pussy clenching down harder on M's fingers for a few moments. She felt M pull in closer, leaning on her, almost hugging her to the wall. Twitches flowed through her body; if it wasn't for M's restraint she doubted she would still be standing.
She was just about to warn that she was close once more when M stopped a moment, having sensed the oncoming orgasm without needing to be told. Thus, K made incoherent noises of need instead, trying to implore her sister to finish the job. It didn't do much.
"Call me the name. Our name, you know the one," M whispered in her ear, hissing this time, stricken by her own need.
"Ww-we're not su-supposed to remember that," K stammered in response.
"Well we both know we do anyway, little sis." M made her ultimatum. "If you want to cum again, you'll use it, that clear?"
"Yyyes, Amelia," K spoke, soft and slow and hesitant. M pulled her slick-sticky fingers out and ran them around K's clit once more, drawing further little noises out of her. "Please, Amelia, big sis, let me- ohhhhhhhhhhh," she moaned after a few moments of tender touch, convulsing as she went over the edge.

"There there, you're okay. Just come back down to me. Love you, little sis," M spoke gently, holding K as her orgasm faded. The latter took a moment to look around, noting rather a wet mess on the floor and on M's jumpsuit's legs.
"Oh wow. Fuck," K said, once she was back on her own two legs. "Do you want-"
"Nah, I'm fine," M replied. She squeezed her sister tighter, then released her. "I should get back to my work, but do take care of yourself now."
Though, as K walked away she couldn't help but notice M grabbing her own breast, rather than any of the tools.
