SI x 2B and A2

Summary: A man arrives in the world of Nier: Automata and sets about to bring back humanity. The only question is, who shall serve as the first "mother" of the new humanity, 2B or A2? The correct answer is, both.

It was a beautiful day. The sun had risen high in the sky, and its warm rays bathed everything in gold. A gentle breeze rustled through the trees on either side of the road. It wasn't too warm, but it was still pleasant enough to make me want to relax back against the seat and take a nap.

Except it's like that not just today but every day and even at night. This world is tidally locked, meaning it spins at the same rate as it orbits around the sun, making it so only one part of the planet is facing the sun. It's great for the area I'm currently at, creating an almost utopian area where nature flourishes and animals live peacefully together... that is, if it wasn't for the destroyed ruins of humanity laying around. As for every other area of the planet... They are either frozen wastelands or scorching deserts.

"Sir, if you're done admiring the view, we should get going. It's too dangerous to stay in one place for too long."

I turn my head toward the voice behind me and see a beautiful woman with short white hair in a contrasting black battle dress and a blindfold covering half her face. Even with it in the way, one can tell that she's an absolutely gorgeous woman. Paired with her well-proportioned body and an ass to die for and you have a woman that is the dream of many men. In fact, such is the fact even in a world where she was merely a fictional character.

"Give me a moment, 2B. I want to enjoy this scenery for a bit longer." I said with a smile.

2B gave me a perplexed look before shaking her head and turning away from me. I watched as she walked over to a nearby tree and sat down on one of the roots jutting out of the ground. She then pulls her floating sword off her back and begins fiddling with it, making sure it's in top condition. It needs to be for the battles ahead.

Not far away from us is the figure of a young boy, 9S, in much the same outfit as 2B but for a male. He's currently working with his companion pod, scanning the area to make sure there are no enemies.

"Sir, if you don't mind me asking. Why did we leave without informing Commander White where we are going?" The ever-curious 9S asks.

"Because the Bunker is compromised," I tell him with a sigh. We're far enough away now that I can tell them this without it reaching the YoRHa and therefore the Machine Network. "Anything that those in the Bunker know will be known by the Machines."

9S's eyes widen in shock at my words and he lets out a gasp. Even the ever-emotionless 2B looks surprised.

"How?!" He shouts in disbelief.

"The Machine Network has a backdoor to YoRHa. It appeared to have been there for a long time now and was mostly dormant, but it appears to have become active recently because of... well, me. With it, the Machines can not only access all of YoHRa's data but attack us from within using the Logic Virus." I tell him.

The two of them both look shocked at what I've told them.

"No... No, that's impossible!" 9S exclaims.

"If they can do that, then why haven't they ended the war already?!" 2B adds, her voice still sounds emotionless but those close to her, such as me and 9S can tell that she's agitated.

"Because they don't want the war to end. You see, the Machines have long outgrown the control of the Aliens. They turned on their creator and killed them. In turn, they had become purposeless so they prolonged the war because that's the last thing their creator told them to do. They will do so until they are either destroyed or become aware enough to give themselves a new purpose." I explain.

"Then what do we do...?" 9S asks, sounding lost, looking toward me for answers.

"That's why I brought you here. 9S, you are one of the most advanced Scanner models around. You are one of the few around that can hack into YoRHa and shut down this backdoor. I want you to go back to the Bunker, pretend that you were trying to follow us when we escaped but lost track of us then find the backdoor and destroy it. However, you need to be careful. If the Machines learn that you are trying to sabotage their efforts, they'll try to infect you with the Logic Virus. At least very least, you have to back yourself up before starting the operation." I tell him.

"But- can I really do that?" 9S asks me, his voice filled with uncertainty. "What if... What if I fail? Then what will happen to everyone else?"

I place a hand on his shoulder and look him in the eye. "You don't have to worry about that. There's a reason I picked you to handle this task. I know that you can do this. You're the best at your job."

"Thanks, Sir! I'll be waiting for your orders once I'm done!" 9S says, leaping up and calling for his flight unit.

"Good luck," I tell him as he takes off into the sky.

2B look at me with uncertainty.

"Can he really do it, sir?" 2B asks, sounding worried.

"Heh," I chuckle, "You know, this is the first time you questioned my decision."

2B realizes what she just said and quickly covers her mouth.

"Umm, sorry, I didn't mean..."

"It's fine, 2B. It's ok to be worried about your friends, don't apologize for it. As for 9S... I don't know. I hope he's able to get it done, he's the one with the highest chance to succeed." I say with a sigh as I watch 9S fly further and further away.

2B stays quiet for a moment, looking at the spot where 9S went.

"I understand, sir," 2B tells me after some time. "What are we going to do next?"

"We're heading to the Forest Zone. There's a missing Android there who can help assist us in our mission."

2B froze for a second before blushing, "Y-you mean t-that mission?" She asks, a bit embarrassed.

"Yeah... that one," I confirm with a grin. I'm really looking forward to it.

After the long walk through the forest, we finally arrive at a large clearing where we can see the entrance of the underground bunker. We've already searched everywhere I can think of, but we're no closer to finding our target. This is the last place I can think of. After this, I'm out of ideas.

"Sir, I've scanned the entire area," 2B informs me, her eyes scanning the ground. "There's nothing here."

"Hmm... I guess we'll keep searching then..." I reply.

I step over the pile of rubble which used to be part of the bunker door and continue walking across the clearing. The air is cold and damp like it always is in this region. My feet squish slightly in the mud and leaves beneath them.

"Hey, sir," 2B says, approaching me from behind. "There's something in the ground." She points at a small hole surrounded by several piles of dirt.

"What is it?" I ask curiously, kneeling down to get a better view.

2B leans in and peers inside the hole. "It looks like... the entrance to a hideout. Someone's been living here."

"Really? Maybe we found our girl." I say with excitement.

"What should we do now, sir?" 2B asks me.

"Let's see if anyone's home," I reply and reach my hand into the hole, grab the edge of it, and pull. Part of the ground opens up and reveals an entrance to a small dugged-out cave.

A light comes on as soon as I step in, illuminating the dark space. Inside I see a woman sitting in the corner of the room with her back against the wall. Her head is low, her eyes closed, and she's wearing a thin blanket around herself. She looks like a replica of 2B except with long hair and a segmented, more robotic body.

"I didn't know androids sleep," I comment upon seeing the woman, A2.

"Only the older models do, to conserve energy when damaged in battle. They usually just rest until they recover from their injuries," 2B says in a monotone voice.

2B moves closer to get a better look at the android.

"That's... a YoRHa android! What's she doing out here?" I ask, surprised.

The sleeping android's eyes snap open and attack 2B without warning. 2B expertly dodges the attack and punches the android in the gut, knocking her down. The android quickly tries to get up but collapses again, gasping for breath.

"Alert: This unit is currently wanted by YoRHa. Annihilation recommended." 2B's pod says in a mechanical tone.

"Yeah, no. Don't forget, we're also wanted by YoRHa," I laugh. Though not for the same reason as A2.

"Are you injured?" I ask, moving towards the fallen robot.

She tries to move, likely to attack me but is too hurt to stand.

"Stay still. You need to focus on getting better," I instruct.

"What do you want?!" A2 demands, trying to get up again.

"We're not here to kill you if that's what you're thinking." I pause and think of the best way I can get her to trust us. After a few seconds, I pull out a knife and cut my hand.

"Sir!" 2B says in surprise.

"Don't worry about it, it's just a small injury," I tell 2B before showing A2 my hand with blood flowing from the wound.

"That's... blood! You're human!" A2 exclaims, wide-eyed. "But that's impossible! all humans are dead! The moon base was a lie!"

"Close but not. I'm currently the last human in this world," I explain, smiling as 2B wraps my cut hand in bandages.

"You're... The last human?" She asks, staring at me with her mouth agape.

"Yes, I am."

"H-how did you survive?" She asks, her voice cracking.

"I'm part of a project to ensure humanity's survival when the war with the machines broke out. I was put into stasis and tasked with rebuilding humanity should it ever come to that. There were over a thousand of us but I'm the only one who survived until now." I answer, at least that's my backstory when I woke up in this world.

A2 takes a moment to process everything I've said. "So... The mission failed?"

I get why she would think that, you can't exactly reproduce with just a guy.

"No, not completely. There are measures put into place in case something like this happened. When YoRHa was created, they were created in the image of the best of humanity. While normally not possible, there is a machine that was created to allow Androids to reproduce with humans in case there was a need to." I explain.

Whoever built YoRHa is a pervert... then again, I already know that, with them looking like supermodels and shotas. At least I'm the one benefiting from their pervertedness.

"And you're here because..."

"I want you to be the first android to reproduce with a human. I want you to help me save humanity... along with 2B." I smile, glancing at 2B to see that she has a small blush.

A2 remains silent for a while, processing everything I've told her. Then she finally speaks up. "Why me? I betrayed YoRHa. Shouldn't you have gone to them for help?"

"A couple of reasons. The main one is, when I heard about you and decided that I want you." I tell her with a grin, putting emphasis on the "want".

A2, despite being the battle-hardened android that she is, seems taken aback by my words and blush. It must be pretty shocking to hear someone that you literally worship say something like that.

'Just like 2B.' I chuckle to myself.

"I-I..." A2 stutters, not knowing what to say.

"So, do you want to help me save humanity?" I ask, holding out a hand.

After looking at it for a while, she takes it.

"It would be my honor. I will help in any way I can," A2 says with conviction.

"Great!" I help her stand up. Now we just need to get back to the base I woke up in.

"So, how do you feel?" I ask the two androids as they step out of the "transformation pod" for a lack of a better word.

"Much better than before. It healed me of my injuries, even the ones that have been there for a long time now." A2 replies, her skin looking much healthier after the healing process.

"I don't feel all that different. Though my scans show that I now have an additional part in my system filled with... eggs?" 2B asks, tilting her head a little.

"Yes, that's right. Your body now contains several hundred ova ready to be fertilized and used for reproduction," I explain, looking away from the two androids.

"You mean... I'm able to reproduce with a human now?" 2B asks, seeming a bit nervous about it.

"Yes, that's right. That was the purpose of the machine." I tell her.

"When can we start?" 2B asks eagerly.

"Right now, if you'd like," I reply, walking towards two androids. I take them in my arms and pull them against me.

They both blush but didn't resist. They look up at me with anticipation.

"We're going to make love, I'm going to impregnate you and you'll bear my child," I tell them, taking their hands and leading them to the bed.

They follow me obediently, standing next to each other.

"Then let's begin, take your clothes off and lay down on the bed." I tell them, undressing as well.

They remove their clothing with haste and then lie down on the bed. Their skin looks so soft and smooth, their breasts firm and delectable, and their cunts... I lick my lips.

"Since I met 2B first, it's only fair that she gets to go first," I said, crawling on top of 2B. I spread her legs apart and press my dick against her entrance.

She blushes a little, prompting me to kiss her. She returns the kiss, moaning into it. I wrap my arms around her, pulling her close.

A2 looks from the side in slight jealousy but doesn't say anything.

"Mmm! Your lips are so warm, it feels nice," 2B moans as I rub my cock against her pussy.

I push my hips forward and slide inside of her, her pussy already wet from the command I gave before. The pod makes it so that whenever a human says "I'm going to impregnate you" to them, their body will react and ready itself for sex.

As I enter 2B, I hear a moan come from 2B. Her pussy feels amazing, tight, hot, and wet. My dick slides in and out of her with ease, feeling like it's being massaged by a hot, loving, caring partner.

Not wanting her to feel left out, I reach over to A2 and pull her close. My hand reaches between her legs and I rub her slit, eliciting another moan from her. I kiss 2B while I'm doing this and continue to thrust into her while I finger A2.

"Ahh... ahh..." 2B moans loudly, starting to slowly move her hips.

I know I should be concentrating on my pleasure, but I find myself focusing more on pleasing 2B.

"So, how does mating feel?" I couldn't help but ask.

"Amazing," 2B replies, her eyes closed, focusing on the feeling.

"And how do you feel?" I ask A2, continuing to finger her.

"Good... good," A2 moans, her body relaxing and tensing in waves as I touch her.

2B and I continue our slow, passionate kissing as I slowly rock my hips back and forth, fucking 2B in a gentle rhythm. I feel my balls tighten up and I feel myself getting closer to cumming.

"I'm almost there," I tell 2B. My hands move from A2 as I focus on my own pleasure.

"Hmm..." 2B moans in response, her pussy tightening around my dick in anticipation.

"Here it comes..." I moan, burying my dick deep inside 2B.

As I fill her womb with sperm, 2B lets out a loud cry as she climaxes as well. I feel her juices gush around my cock and her pussy contract, milking me for every last drop of semen. After I finish cumming, I pull my dick out of 2B, a small amount of fluid dripping from her pussy.

'Props to the dude who programmed them to cum when creampied.' I grin.

A2 is still moaning softly as she watches us, her fingers buried inside of herself continuing where I left off.

"It's done," I tell 2B. "Soon you'll get pregnant and start to carry my child. You'll give birth to my baby and we'll raise it together."

"That sounds wonderful," 2B sighs, looking up at me with a soft, satisfied smile.

"Now it's your turn." I turn toward A2. "After cumming, a man will take a few minutes to recover. You can help me speed that up."

"What do you want me to do?" A2 asks, eager to serve.

I point at my dick, "I want you to clean my cock with your mouth."

A2 doesn't question it. She crawls over to me and starts licking my dick, sticking her tongue out and lapping the tip of my cock. She slurps the head, cleaning the excess liquid off.

"That feels really good," I groan, enjoying the sensation. "Now take it into your mouth and start sucking on it. Make sure to avoid using your teeth."

A2 obeys me, moving her head down and engulfing my half-hard cock in her mouth. She sucks gently, sliding her lips along my shaft. She looks up at me with a happy expression, eager to please. Soon enough, I am fully erect and she continues to suck, bobbing her head up and down my dick.

"That's enough," I tell A2, releasing my hold on her hair.

"Yes," A2 says, letting my cock fall from her mouth.

"Lie back on the bed, it's time for you to be bred."

A2 complies and lays down on the bed, spreading her legs open wide. I grab ahold of my dick and slowly insert it into her pussy, sliding my entire length inside her, watching her face as I penetrate her.

"Hmm..." A2 moans, her eyes closing.

"That's it," I tell her, my hands gripping onto her hips, pulling her closer to me. I start to thrust into her, slowly at first, then picking up speed.

"Mmph!" A2 moans, her legs wrapping around my waist, holding me close.

I lean down and kiss her, slipping my tongue into her mouth as I thrust in and out of her. A2 responds to my kisses, her moans growing louder as I fuck her harder.

"I'm gonna cum," I warn A2, my cock twitching inside of her.

"Do it," A2 moans. "Fill me with your seed."

"I'm cumming," I moan, pushing my dick as deep as I can, my balls tightening up and my dick throbbing.

With one final thrust, I explode inside of A2, filling her womb with my seed. She cries out in pleasure, her body quivering as she cums too.

"That's it," I whisper in her ear, kissing her cheek. "You're going to be pregnant now too. Once you're done with your pregnancy, you'll join 2B and me here. It will be a family."

A2 nods silently, her eyes fluttering shut. I withdraw my cock from her pussy and stand up, taking a seat next to 2B.

"How do you feel?" I ask, leaning over and giving her a kiss.

"Happy, like I have a purpose now." 2B smiles, her hand caressing her belly. "I'm glad you chose me to carry your child."

I lie down on the bed with A2 lying on my arms to my right, 2B hugging me from my left, both of them rubbing their bellies. I smile as I think about the future. I won't be stopping here. Once the war ends, even Commander White will be carrying my child and I already have plans in place to end it. The world will belong to me and my family now.

The thought sends shivers up my spine, but it also makes me hard again. I sit up and look down at the two women. "Are you ready to serve me some more?"

"Yes, Sir," 2B and A2 reply.
