"You are the only living humans left on this Earth." She revealed, shocking Rin and Shirou to their cores and making them exchange looks of alarm as she continued on. "For thousands of years it has been this way, we of YoRHa have been given the purpose by the late humanity to fight and destroy the machine invaders. Alien lifeforms came to this planet countless millennia ago and brought with them their machine forces which we have been fighting to this day in an endless stalemate. Most YoRHa Androids like myself don't know the truth yet and would be at risk of insanity if they did, making me one of the few left who knows. The aliens themselves may be gone but their Machine legions remained and since that conflict reached its halcyon many years ago, humanity has long since died with the majority of my people believing them to be alive and in command on a base located on the Moon. I have been instructed by my Commander to give you any information you require in exchange for your agreement to the alliance. That is...if you'll agree to a certain condition first." 2B finished, feeling a bit tingling in her chest as she felt the rising notion of offering her body for sex with the man while they both looked utterly devastated after being told the truth.

"I...knew it, I thought something was off about this planet when we came here, but what she just said confirms it, Shirou. I think we should take what she's offering. We'll need a place to stay safe until Melloi can pull us back to  our world." Rin explained, looking at Shirou from the side and noticing 2B eying him with a peculiar look on her face. "Oh, how rude of me. My name is Rin Tohsaka and this is Shirou Emiya. To make a long story short, we're both...travelers from another world....not of this one, and we are currently stranded here. We would like whatever help you could give us, provided there are no conditions to meet of any kind with your....people."

"There is...one condition and it is...mandatory from my Commander. Would you like to hear it?" 2B asked, making Shirou perk an eyebrow while Rin simply nodded her head casually, with a friendly smile. "Very well, Shirou Emiya, I....would require you to inseminate me. Engage this body in the sexual act of production so it may provide new life, it is quite capable of doing so and can only be done when it is with a virile human male specimen like yourself."

Rin froze in place and felt as though her body turned into stone when she had processed the words 2B uttered just now, leaving a few veins popping up all around her forehead till she couldn't contain herself anymore.

"You want him to....!? S-Shirou is my boyfriend, you...! I..I...know we're desperate and in need of sanctuary but t-this is....insane...! We could be going home any moment now and I---!" Rin cut herself off mid-rant when she looked at her side, noticing the now defunct pair of Harnesses showing no trace of Mana anywhere within their constructs. She was livid and full of boiling-hot frustration right now after having accidentally marooned here with Shirou as the only other living person. She looks back at 2B quickly and bites down on her bottom lip with fists quaking at her side for her mind was in turmoil over what to do about this trade-off for information. 'Uuuurghghhhh! Who am I kidding? We have no leverage in this outside of Shirou's value to these.....crazy, weird sex bots offering us information and shelter from their machine enemies. But how....can Automata produce life? Are they part of some advanced Magecraft or something? I....don't know what we should do.'

She looked at Shirou next, appreciating 2B's silence as the girl was now quaking with indecisiveness over loaning out her boyfriend's seed to these things. It seemed every bit as human as they were, at least from an outward appearance, yet Rin couldn't resist feeling at odds with herself in wanting to do this versus needing to do this. With Luvia it had been different since she was flirting with Shirou, but this Android was literally asking her boyfriend for babymaking sex and Rin couldn't think of a reason to say no to her outside of clingy pride and ownership of her beloved redheaded doofus. Shirou picked up on her obvious signs of distress wrought by conflict and reached over to place a hand on her right shoulder, stirring Rin out of her thoughts and making her gaze into his eyes to see a genuinely kind pair of amber orbs staring back at her.

"We...don't have to do this if you don't want to, Rin. I'm sure Headmaster Melloi will come up with something to pull us back soon." Shirou reassured half-heartedly, feeling genuinely lost and concerned in this post-apocalyptic world they now lived in until he felt Rin reach over to squeeze his left hand and clutch it in comfort. She noticeably exhaled and looked up at him for a moment, giving him a sweet smile before turning her head back over in 2B's direction with a furtive look of unwitting surrender.

"It's fine, Shirou. We....need to do this, because...what if we really are stuck here and those Machine Enemy hostiles they're talking about find us and come for our lives? We may not even be able to access Mana anymore either at some point. Alternate worlds or parallel, theoretical realities often have these kinds of effects on Mages as I've learned about in the archives pertaining to something called Grand Order. We.....should take her up on the offer because we need sanctuary and help learning about this new world we might have to live in. So go ahead, Shirou. Do her." Rin admitted, blushing furiously with slight rage as she saw Shirou blushing rather profusely out of uncertainty now that he was looking at 2B with a nervous smile.

The Android inwardly seemed pleased and removed her 'Visor' from her head, revealing a pair of glowing electric blue eyes that just captivated Shirou entirely, leaving him standing in place. She dropped it onto the ground beside her legging-covered feet and bought each of her gloved hands up to her chest, reaching the white-lace cleavage window of her dark outfit before pulling it open to reveal each of her supple breasts. They were slightly perky yet just as lush and round as a woman's breasts would be, her nipples were poking out now as she had ripped her dress open enough to let each of them fall out into the open. Shirou let out a winded groan of surprise for he was feeling erect already, making his bulge appear before the two girls through his pants while Rin looked on in confusion and arousal.

"Gugh! Right here...!? Now...?!" Shirou blurts out and 2B nods her head immediately to his question as she reaches around the side of her waist, undoing a latch and letting that large puffy dress skirt come off. Almost like a Doll's velcro-latch clothing accessories, it came off and fluttered to the side next to 2B's blindfolds to reveal the white unitard bottom half covering up her pussy from view while clinging tightly to her frame from the midsection. 'S-she's....beautiful....! But is Rin really okay with this...!? I mean, I get that this is a desperate situation, but j-just...how am I supposed to do this with a clear conscience? Make a baby with an Android? Is that even possible?'

"I know what you are thinking, and 'yes' it is. I have just learned it recently myself and would not have believed it if my commander hadn't just told me we could. Apparently, all of  YoRHa's female Androids are capable as we are Techno-organic on a core level." 2B explained and walked up to the 'comfiest' spot in their hideout, which was a padded sleeping mat the size of a mattress somewhere in the center of the floor, and plopped herself down onto it with legs spread wide. 2B even put on a more suggestive smirk so that her facial expression gave off a sultry sign of wanting to be desired by Shirou.

Rin was still stunned speechless and was hugging the side of her arm with a pursed pair of lips, wondering if she should be around for this until she heard 2B's voice call out to her as well.

"You need not be excluded from this either, Rin. While the offer for your boyfriend's seed is absolute, your exclusion is not. And I do not mean that in the sense that male Androids will tend to you, I merely state that you need not be refraining from indulging in his seed yourself. Siring life is important and I have no doubt that you are considerably fertile and attractive to boot. It is any wonder while Shirou, from what I've seen, has been eying her rump  repeatedly before my arrival." 2B addressed, making Rin do a double-take and blink once or twice in a stupor as she looked between Shirou and 2B as though something inside of her lit up.

"T-together, huh? Certainly, the kinkiest thing I've experienced to date and if you don't mind me staying with Shirou, I....I.....I accept! Now hurry up and get those pants off, Shirou...! She's waiting, okay?!~" Rin yelled out loud, beginning to undo her red shirt and unveil her modestly-sized yet ample set of equally perky sits in a brasserie to Shirou. The ginger-haired Survivor of Fuyuki simply stared at her in wonder, feeling his cock grow harder and stretching his pants even wider till 2B decided to take action. The Gothic-dressed Android got off of the sleeping mat and brought herself before Shirou's waist while he was standing up and still gawking at Rin undressing herself in a hurry.

She brought each of her gloved fingers over to his crotch, earning his interest and stroking his arousal even more as they undid his zipper and hastily pulled down his pants. Before Shirou could say anything, 2B had his cock out fully sprung and absolutely erect in its turgid twelve-inch glory with a width as thick as a person's wrist. It was such a marvel of virility that 2B expressed genuine surprise and looked up at him from beneath his waist.

"My, you are quite virile indeed. Inseminating myself with your sperm and conceiving your child will be quite the experience indeed, and do not think that YoRHa will be done with you just impregnating me, Shirou Emiya. But I digress, to maintain peace between our alliance it shall only be the two of us sharing your seed....at least for the time being anyway.~" 2B said, feeling intrinsically sultry and increasingly aroused, which she didn't even think was possible as she began rolling her hands all over the thick slightly-curved shaft of Shirou's penis like so. They sensually grooved all over the contours of his phallus, experimenting by prodding spots that 2B considered to be heavily erogenous areas like so.

"Mmnghgmhh! Hmmgnghh! Ooaahhh...! Hell....! Your hands feel as firm as an iron-vice, but you're touching me so softly...and smoothly too. Mmhmmh..! Do what you want then, M-miss 2B, as long as Rin is okay with it and YoRHa gives us all the help we need. I--aaagaaagghghhhhh! Oohhhhhh...man!~" Shirou cried out when he felt the sudden suction of 2B's lips surrounding his entire cock from the bottom of the tip only with her surprisingly moist tongue slithering around it from underneath. She kept her gloved fingers held around each side of his shaft from the hilt, gingerly stroking Shirou's length while steadily pumping the first couple of inches of his cock into her mouth as she eyed him carefully to gauge his reactions. 2B was determined to see how best Shirou would like it to further stimulate his libido and make him ravish her as intended.

"Hhmmmhmnh...*Schluruppp...schluupp..schlurppp..schlurppp...schlurpppp..sllrp! Chup!* Mmnnhmmh....delectable, youthful, and full of vitality. I believe you may be an ideal breeder, Shirou Emiya. Mmhm...!~" 2B mouthed momentarily, rolling up her face from one side to another while having her tongue bathe nearly all over Shirou's dick in her synthetic saliva. He honestly felt she was as real as an actual girl, leading him to wonder just how advanced were Androids in the future if they could be nearly identical to a human being. So far, Shirou wasn't fully convinced 2B was an Android till he remembered her mentioning that she was techno-organic like all the rest of YoRHa. She bobbed and swerved her head fluidly, tasting Shirou's cock while keeping it in a vice-like hold between her fingers. Rin watched her stroking his cock expertly with a firm hold of her hands and it was quite honestly making the girl feel rather competitive.

She wanted to beat 2B at her own game and would decide to worship her boyfriend's cock as soon as she saw an opening. Right now, 2B simply finished shedding off her pants and removing the rest of her red-lace undergarments, presenting her naked body to Shirou when he turned to look in her direction.

"Gnghghhh! Nghgh! mnghh! Tohsaka...! You look..aaahhh...so beautiful...! Mmnghmmm! Oohhh....my God, she sucks like a literal vacuum...! Guugghhh!" Shirou cried out, feeling 2B going even deeper to where most of her slimy, synthetic throat covered up half of his cock in its walls of moist flesh. She kept her tongue wriggling sensually around his length, furthering Shirou's growing lust while she squeezed her lips tightly around the base end of his shaft.

"Mmnmmb...mmmmnb..mmnbn..mmmnbnh..mmbhn! *Schllluuuupppp..schuooopp..schlupp! Pop!* There, I believe you are fully erect and riled up enough to goad into copulation.~" 2B said after sucking him off in lurid, long strokes of her oral flesh before finally popping her lips off with a smack of saliva between her lips. From out of the corner of her eyes, she noticed Rin was now naked as well and was currently fondling herself to the show by cupping one of her breasts in her hands with a hand between her legs stroking her pussy sensually. 'Hmmm, it seems she appears to become very stimulated with the act of voyeurism. Perhaps this arrangement really can work to everyone's benefit, though I will have to inform Commander that Shirou will not partake in doing the same to all the other female Androids in the Bunker just yet.'

She looked up at him from below, seeing him pant and exhale excitedly as though his blood was boiling from the inside. His cock was also angrily twitching with need, showing 2B it's engorged and letting her take notice of how thick his bloated-looking balls seemed to be when she looked at them from below. She deemed him ideally healthy for breeding and could perhaps copulate for hours on end, guaranteeing pregnancy for certain. Nodding to herself and scooting back to where she was back on the bed, 2B rested her rump on the comfortable surface with her legs spread wide in a suggestive pose. Shirou's eyes became widened with desire as he watched her reach down to slip open the bottom of that leotard piece covering her sex, revealing her pussy to him in full.

The soft, velvety flesh of her labia looked as pure and 'real' as any normal woman could possibly. 2B didn't have any pubic hair above her mound, for obvious reasons, but she had a very tantalizing pussy just glimmering with moisture in its desire for his seed. Shirou felt compelled to obey its command and quickly pulled off his shirt while looking at Rin once again to see if this was okay. To Shirou's surprise, he saw the brunette ravenously stroking herself to the show and fondling her tits in tandem when giving him a blushing 'just do it' look.

"Go on, do it. Fuck her...then do me next, Shirou. Watching is fun and all, Lord knows it is for me, but.....I want to have your baby too, you know.~" Rin stated softly with a smile, making Shirou's heart melt a little as he finished pulling off his shirt and stepped out of his pants naked.

"Alright, Tohsaka, for you....both of you. I'm giving myself entirely to this...agreement we have, so get ready, 2B, because here I come." Shirou said with resolve, causing a fluttering inside of 2B's chest as she remained on the bed partially naked with her breasts exposed and her pussy now uncovered. She watched that lumbering rod of thick, male flesh bobble stiffly in his steps as he came to her with a hand gently nudging her chest so she could lay back. 2B obliged this and rested on her back with legs spread-eagle, anticipating a missionary position while Shirou placed himself above her. His cock was held above her sex readily and he planted one hand into the mattress closest to the right of her angelic face, looking at her with sexual desire in his eyes.

"Yes, as she says; do it. Do...me, Shirou Emiya. I've often been curious about how males and females copulated back then. So do me the honor of breeding me and allow me to assist you in breeding your girlfriend too.~" 2B said in a mist, alluring voice just before feeling the nub of Shirou's cock-head pushing through her sex with a shove.

*Squelcccchhh!*

"Aaaagggngnnhhhhh! Mmmggnhmm! Ooohh....such...intense sensation." 2B whimpered loudly, feeling the foreign sensation of something as large as Shirou's cock pushing through her silken slimy folds of synthetic flesh and stretching her out as he did. He started pushing all the way to the waist, resting his pelvis between her thighs and feeling her legs climb up to wrap around his buttocks while Rin looked on with a perverse look of lustful desire in her eyes. She started stroking her sex even harder with her fingers twisting around her vaginal flesh, watching from a good angle that Shirou's cock sunk in nearly all the way inside of the Android woman's body.

Her back was arched and her breathing came out in hitched heaving inhalations for this was a new feeling for her entirely. While Androids could feel pain, albeit to a lesser extent, they could also experience a myriad of other sensations outside of the outlawed use of emotions when in battle. 2B was feeling overwhelmed and filled with a growing feeling of pleasure as she felt Shirou's cock pushing open her insides on its way to her synthetic womb like so. He kept their bodies aligned in a missionary position and started seeing 2B moan in loud breaths and groans of enjoyment as he began.

"Mmnhmmmghh! oohhhh....man! Uuggnhh! It's so slick, tight, and slimy...! Gnnghh! Here I go now, okay? You wanted this...you got this...! Uuuh..uuhh..uuhh..uuhh..uuhh..uuh.....uuh..aaammgnghh!~" Shirou grunted out loud, pressing his waist into 2B's crotch and feeling the soft pelting of her skin colliding with his while her legs kept themselves locked around his backside as they went along. In and out his member dipped into her slippery folds, plunging the external visage of her cunt as well as churning her synthetic walls from the inside in a rampant pace of pumping. His balls were tapping against her inner thighs and nether region, adding a bit of spice to 2B's electric surge of emotions as well as sensitive pleasure.

She brought her hands up to latch around both sides of Shirou's brad shoulder blades, embracing him completely as she tilted her head back and enjoyed the tantric plunging of his cock into her core.

"Aaahh...ahh...ahh....ahh....ahhh..ahh....ahh...aaaaagngnh...! Mmnghgmm! This is...aahhh..aahhhh...aahhh...so intense....and pleasurable...! Why...did I argue with the Commander before...? Haaahahhhhh! Uuh...uuhh..uhuh....uuhaaahahh!~" 2B cried out in ecstasy, feeling the slick squelching of her cunt wrapping tightly around his length. Her tits were bouncing voraciously with every movement they made, bouncing higher and higher as they went with Shirou raucously bucking into 2B's admittedly soft body like an animal gone wild.

"Mmngghmhhhhh! I never thought I'd be so turned on by something like this..! Mmghghh! Uuaahhh! Go get her, Shirou...! Make that...sex-bot satisfied...so you can have me next. Mmmmnhmm!~" Rin said to herself, dipping her fingers into her twat as fast as Shirou's cock pushed into 2B's pussy from above.
