A/N: Probably my last one-shot for while. Am running out of steam and ideas.

SI x Team RWBY

Summary: A man succeeds in creating a miracle and promptly gets rewarded for it.


After plugging the last of the wires in, I take a step back and admire my work. An Arc Reactor, named after the one made by a certain genius billionaire playboy philanthropist… or was it made by his day?... whatever. That doesn't matter. What matters is that I finally built an Arc Reactor!

Sadly, even with my upgraded smarts, I haven't found a way to make it smaller. Currently, it's the size of a king-size bed. It also doesn't run on palladium since I have no reliable source and not unobtainium since I don't know how to create it. Instead, it runs on Lightning Dust Crystals.

Dust, when used, turns from a solid into a type of energy but because there is nothing controlling the process, most of the energy is lost. Yet, even with most of the energies being lost, just a small canister of dust, one big enough to fit into a bullet, can produce almost half a trillion Watts. That's enough to power New York City for over a month and it was made using only dust, not a dust crystal.

Using my Arc Reactor and a Lightning Dust Crystal, I'm able to slow down the process of extracting energies and decrease the energy lost to only 1%, which is still a lot of energy being lost but it's a lot better than using it the normal way. Just one dust crystal in my Arc Reactor will last for more than 100 years and provide me with enough energy for the next phase of my project.

"Lai, commence operation CITS." I order my A.I. She's quite advanced but she isn't a True AI like Jarvis or Penny yet.

"Right away Sir. Zero-Gravity nodes activate. Underground pillars detached. Repulser on stand-by. All systems running at 100% capacity. Ready for take-off on your signal Sir." Lai replied. Zero-G technology, something I was able to make thanks to my Semblance.

"Warn the town."

"Already done sir. All civilians are in the safe rooms."

"Good, then it's time to take this place to the sky." 6,000 ft should be high enough to get away from most Grimms while still being low enough to not be covered in snow all year round.

"Affirmative. Take off in 3… 2… 1…" I hear the familiar sounds of a repulser winding up before the ground starts to shake. Then with a loud BOOM, a gigantic section of land separated from the ground, and water rushed in from all sides to fill the gap.

I walk outside to admire my work. After 10 years of hard work, I finally did it! Operation City In The Sky. I made a floating island and I've done it without needing to use a relic created by Gods! Not only that, the floating islands have plenty of area for farmlands, a giant lake with a snowcap mountain to supply water, and enough space to house millions of people even without counting the farmlands.

"Repulser deactivated. Zero-Gravity field stable. Congratulations Sir, the project is a success."

"Thanks Lai. You can tell everyone it's safe to come out now. Oh, and make sure to raise the forcefield. I don't want anyone falling off the island."

"Yes Sir." Lai replied in her monotone voice.

I really need to find out how Tony and Dr. Polendina turned their AI into an actual thinking being. Having a helper who can keep up with me that doesn't need to wait for my orders will be nice.

"Now all that's left to do is clear out the Grimms still on the island and we will officially be Grimm free… on the island anyway. Lai, deploy the drones, capture any Grimms you can find, and throw them off the Island." I ordered.

"Already done, sir." Come Lai's reply.

One thing about Grimm is that they can't be killed… permanently at least. Once they die, their "essence" for a lack of a better word, dissipates and gathers together into pools of black tar-like substance that pump out more Grimms until the pool runs dry. Of course, if you keep killing the Grimm, the pool will keep absorbing their "essences" and spawning new Grimms leading to a never-ending cycle. The best way to deal with Grimms is to trap them or move them elsewhere where they won't be able to bother people.

"Sir, you got a call incoming from General Ironwood." Lai's voice echo from the coms.

Ah, right. I almost forgot about him. I wasn't born rich in this world and the whole reason I managed to get to where I'm now is by selling weapons to Ironwood/Atlas. I did sell to other Kingdoms too but the majority of my income comes from Atlas since they're my biggest buyer. I have no problem being a "death merchant" because most of the weapons I sell will only be used against Grimms.

"Patch it through," I ordered.

"Affirmative!"

Lai's hologram then fizzles out and is replaced with one of Ironwood.

"Hey General, how's it going?" I greet the guy casually.

"Mr. Black, I heard your latest project is a success." The general replied, ignoring my greeting and impolite manners.

"Yeah, 90% of Patch is now airbound."

"Excellent, does that mean you'll start working on other kingdoms and capitals now?" Ironwood asks.

"Yeah, I'll start with Menagerie, Vacuo, Mistral, Vale, then Atlas," I answer.

The general frowns, "Any chance I can convince you to reconsider? Say, start with Atlas or even Vale first?"

"Nah, I'm doing it in terms of needs. Vale and Atlas are the two safest kingdoms to the Grimms. Compared to them, Menagerie is lacking quite a lot." Plus there is this hot catgirl, her wife, and their Beacon Academy teammates I'm trying to bang. They made a deal that if I can take Patch and Kuo Kuana into the air, they'd agree to a threesome with me.

"I see… I wish you luck, you're going to need it. Ironwood out." Ironwood said after a few seconds of silence. He knows he won't be able to convince me otherwise once I put my mind to something. He tried and failed multiple times in the past.

"Yeah, no kidding." Getting Menagerie to agree to the plan is going to be hard since I'm not a Faunus. Thanks to the White Fang and racism in general, there is a lot of distrust between Menagerie, the county of Faunus, and the rest of the human world. The only reason why I think I can convince them is because I now have proof I can do it and have their "princess" backing me up.

At least things have been loosening up in the past few years since the White Fang was decommissioned. Largely thanks to my plans, Ozpin's help in legislation that opened up jobs/housing for Faunus in places without much racism, and my upgrade to this world's entertainment system.

A few days later, as I was getting ready for my trip to Menagerie, I received a text message and an address with a picture attached to it... a picture of 4 hot and very much naked girls. My dick twitched in my pants as I read the message: "Waiting for you at the usual spot, hurry up!"

"Lai, reschedule my flight to tomorrow, no, make it two days from now. I have somewhere I need to be." I tell my AI before flying out of the house, both figuratively and literally.

I reach my destination in record time, appearing in front of a giant treehouse. There are no other buildings around it, only trees. I immediately notice four figures standing by the entrance in only their underwear.

The tallest one in the group is Yang Xiao Long, a blonde-haired girl with bright lilac eyes and a fiery personality. She looks so hot right now, her long hair tied up, revealing her toned body. Next to her is her wife and the catgirl princess, Blake Belladonna, the black-haired beauty with a slender figure and a curvy butt. Then comes Weiss Schnee, the white-haired woman with fair white skin and icy blue eyes. She has a petite figure and a small bust but she makes up for it with her athletic build and rock-hard abs. Last but definitely not least is Ruby Rose, the sister of Yang and girlfriend of Weiss with black/red-head silver eyes. She's the youngest of the group and barely taller than Weiss but she definitely doesn't lack in the tits department. Her breasts have grown quite a bit in the last few years and are now big enough to rival that of her sister.

I officially met the team back in their Beacon days when I hired them to protect me on a project I needed to do outside the safety of the walls. I seduced them one by one and bedded them back then, even with them fully knowing that I was going after the whole team. This was before they decided to go out with one another. Over the years, I managed to convince some of them into doing threesomes and even some foursomes but never together as a whole team. This is the first time we're doing this all together.

"Told you that'd make him get here quick," Yang says with a smirk. She's still her confident usual self despite being nearly naked.

Blake rolls her eyes, "Whatever, let's go inside." and heads into the treehouse.

The rest of us follow her inside.

"A-are we really going to do this?" Weiss asks nervously with a blush.

Yang smirks at her, "Of course, we're not stopping you from joining in but you did promise and besides, it's not like you haven't done something like this before. I seem to remember you and Ruby enthusiastically serving him in his office when we visited him to discuss our wedding. And when he got back, we saw the three of you having sex in his bed."

Weiss blushes brighter, "Oh god, you did see that?!"

"Come on, it's fine. We all know how much you love his cock," Yang says with a laugh.

Ruby giggles, "So true! You'd even said you love it as much as you love me one time. It's kind of cute." Her face's a little flush. She's both excited about what they're going to do and a bit embarrassed to be involved.

Weiss cover her face in embarrassment, "I thought you said you'll never bring that up again!"

I chuckle, "As much as I like what's going to happen, I thought we agreed to do it after Menagerie."

Yang laughs, "That's basically a done deal already. Besides, you've been so busy lately that we thought this would be a great way to relieve stress."

Blake nods, "And I want to thank you, personally before we leave for my hometown."

I turn to Ruby and Weiss, "And what about you two? How did they get you to agree to do it early?"

Weiss turns red, "Well..."

"Ruby's been wanting to do it with the whole team around too and Weiss can't say no to anything when it involves you and Ruby together," Yang adds, seeing Weiss blush harder.

"We're just happy to help." Ruby giggles and hugs me tight.

"Damn, that's a lot of enthusiasm. Alright then, if everyone's here, let's get started." I say, taking off my clothes. Just the sight of the girls and the thought of what we're going to be doing already made me rock hard.

"So, do you girls have anything planned?" I ask.

Blake pushes me down onto the couch, "Just sit back, relax, and let us take care of everything."

"I can do that," I grin.

Weiss and Blake go around the room and sit on either side of me while Yang and Ruby kneel in front of me. Weiss gives me a kiss and Blake presses her breast into my arm on the opposite side.

"Get ready for a sisters tag team paizuri!" Yang declares as she and Ruby take off their bras. The moment they pull them down, my eyes are drawn to the pair of big boobs in front of me. They look pretty similar, except Yang's are fuller and bigger while Ruby's are a little smaller and perkier. Both are on the big side, though, making them perfect for titfucks. They sandwich my rock-hard cock between them and start massaging my shaft with their breasts.

"Haaa..." I release a content sigh, "This is the best after a long week's work."

"Yeah, there's nothing better than relaxing and getting a nice massage." Blake smiles and starts rubbing my shoulder. Seeing Blake, Weiss starts massaging my other shoulder too.

"Or in this case, a cock massage," Yang adds, squeezing her breasts together to increase the pressure.

"Mhm... You're right." I groan. The feeling of being sandwiched between two pairs of breasts is heavenly. The fact that they're both sisters only makes it better.

"Oh, I'm glad you're enjoying yourself!" Ruby giggles, "But I think it's time to step it up!"

She looks at Yang who nods, "Sounds good to me."

They lean in close, kissing and licking my shaft while their hands continue to rub their breasts together. This feels amazing, especially since they both got very skilled at giving head. All I can do is groan in pleasure as they suck and lick my dick. I run my fingers through their hair as I feel my cockhead getting covered in spit.

Blake and Weiss look up at me, smiling. They sit up over me and start kissing me, alternating between each other. Their tongues swirl around mine as they moan into my mouth. Every now and then, one or the other will give one of my nipples a pinch or tug. It's a small touch, but it's enough to send tingling sensations throughout my body.

Eventually, Yang and Ruby stop their titfuck. Yang gets up and takes my dick into her mouth while Ruby starts sucking on my balls.

"Mm!" Yang moans around my cock, slurping as she deepthroats me.

"Mmph!" Ruby hums around my testicles, rubbing them with her lips.

The sensation of having both my sisters' warm, soft mouths on my cock and balls is incredible. I groan and grab onto the back of their heads, pulling them closer as their tongues dance and swirl around my sensitive flesh. I can't hold out any longer.

"Ahh, fuck! I'm gonna cum." I warn them.

Yang pulls away from my cock and Ruby follows suit almost immediately. They squish my now saliva-covered dick between their breasts again and start jerking me off. Soon, I feel myself building up more and more. My hips buck and I thrust my cock deeper into their cleavage, eliciting loud moans from both sisters.

"Fuck..." I breathe, trying to hold on, "Cumming!"

With a grunt, I shoot rope after rope of hot cum straight into the two's waiting mouths. It splashes all over their face and down their chests. Both gasped, surprised by how much I came. But they quickly recover and start swallowing my load, eagerly gulping the semen that landed in their mouth before cleaning each other off as they make out.

"Mmmph!" Yang swallows my seed. "Tasty~"

Ruby agrees, "Mm! Yummy!"

Once they're done Yang and Ruby take turns licking my shaft clean. They lick up every last bit of cum they can find until it's completely clean. After they've finished, they turn towards me, grinning widely.

"Now, who wants to ride this bad body first?" Yang asks, stroking my dick.

"Me!" Ruby answers without hesitation. She climbs on top of my lap and straddles my waist, placing my cock against her pussy, and moving her panties to the side.

"Alrighty then." Yang smiles.

I notice that Weiss is looking at Ruby in jealousy, whether it's because she was too slow/embarrassed and didn't get to go first or because I'm going to be fucking her girlfriend, I can't tell. It's probably both.

"Ready?" Yang asks Ruby, who nods.

"Go!"

Ruby sits down on my cock, slowly lowering herself onto it. Her wet, hot pussy stretches around me as she impales herself on my cock. With a gasp, Ruby sinks all the way down on my cock and begins riding me.

"Gyaahhh! Mm! Haha..." Ruby moans as she bounces up and down on my lap, "It's so big~!"

"Mm... Mmm!" Yang moans, watching us as she starts to masturbate.

Her hand slides up and down her pussy, teasing her clit. From time to time, she'll pinch it and pull it between her thumb and finger, causing her to moan loudly. Seeing Yang like this, Blake stops making out with me and heads toward her wife. The two kiss passionately as Blake rubs her tits together. They reach for each other's sex and begin fingering each other.

"Awww, fuck! Ugh!" Ruby pants as she rides me, "Uuuuuhhhh~!"

Weiss doesn't watch long, though. She climbs off the couch and kneels in front of me, taking over Ruby's previous job of sucking my balls. I can't help but groan in pleasure as she runs her tongue up and down my sack while her girlfriend continues to bounce up and down on my dick.

"Hnngg!" Ruby cries out, "Haaaahhhhh!"

She bucks her hips, riding me harder. She wraps her arms around my neck and grinds her pelvis into mine, moaning. Yang and Blake watch Ruby ride me and continue to play with each other. They kiss and fondle each other, moaning softly.

"Oh god, haa!" Ruby cries out, "Haahhh! Oh fuck, fuck, fuck! Fuck! I'm going to cum!"

She slams her ass down on my cock, burying it inside her pussy. Ruby moans loudly and grinds her crotch into me as I feel her orgasm wash over her.

"AHHH! M-Mmph!" Ruby whimpers as her pussy squeeze my cock, "AAAHHH! AAAAAHHHHH!"

Ruby's entire body tenses and she shudders, shaking as her orgasm rips through her. She comes so hard that I feel my balls tighten up and I lose control of my own orgasm. I grunt and my cock erupts inside Ruby's tight cunt, shooting ropes of cum deep into her womb. Ruby's pussy contracts around my cock and milks my shaft as I fill her with my seed.

"Mmph~!" Ruby pants, collapsing on top of me, and grins, "That was fun!"

Yang looks over at Ruby and smirks.

"Well, you did pretty well there." She says.

Ruby blushes a little and giggles, "Thanks."

Ruby recovers enough and gets off of me. She takes a seat next to me. I look down at Weiss and see her still kneeling in front of me, staring at my cock with desire. She licks her lips and then moves forward. Her hands wrap around my shaft and she strokes it gently, making it hard again.

"Do you want to go next?" Ruby asks.

"Yes!" Weiss replies breathlessly, too horny to worry about embarrassment.

Weiss removes her bra and panties, revealing her naked body. She walks over to me, turns around, and squats down in front of me, placing my cock between her thighs. She rubs my dick along her pussy, teasing herself. When she's ready, she lowers herself down on my cock and begins riding me.

"Mmm! Gyaahh!" Weiss moans, "God it feels huge inside me!"

Weiss bounces on my cock, riding me. I grab her tits from behind and play with them, squeezing and groping her soft flesh.

"Ah... haa! Ah! Mmph!" Weiss cries out, "G-Gyaah!

Ruby joins us, sitting on the armrest beside me and rubbing her breasts against me. She turns my head toward her and kisses me, our tongues dancing together.

"Mm, that's so hot!" Ruby whispers into my ear.

We keep kissing as we continue to make out while Weiss rides my cock and Yang and Blake are off in their own little world. Weiss keeps bouncing on my cock, moaning, and panting. Eventually, she starts to get close and bounces faster. I grab her hips and force her to ride me harder.

"Y-You're so big, it feels so good!" Weiss cries out, "I'm almost there! So close~!"

Weiss' breathing becomes erratic as she grinds her pussy against me, getting closer.

"Here, let me help." Ruby leans over and sucks on one of Weiss' nipples, giving it a few quick tugs.

Weiss gasps loudly and shakes as her orgasm hits her. Her back arches and she cries out, shaking violently as her pussy squeezes my cock and as if trying to milk my cum out of me. Having already cum twice, I didn't manage to reach my own climax, but I don't mind.

"Mmph!" Weiss moans, "Mmph! Mmph! Mmph!"

Weiss collapses onto me, her legs trembling beneath her. She panted heavily, her eyes closed, and her lips parted.

"I-It was nice." Weiss murmurs, still recovering.

Ruby smiles and helps Weiss off of me, pulling her to lie down on the couch. Ruby lays down next to her and starts kissing her. I watch them for a few moments, enjoying the show. My cock is still semi-hard, and I know I'll be able to get another round or two in.

"My turn!" Yang exclaims.

Yang gets off of Blake and climbs up on the coffee table, holding her legs up and her feet near her head. She spreads her legs wide open and looks at me, "Come on, I want to try the mating press. I want to feel your cock deep inside me!"

Yang's pussy looks so inviting. It's already wet and glistening with her juices. I get off the couch and position myself between Yang's legs. I can see her pink insides peeking out from between her pussy lips. I hold her legs in place as I place the tip of my dick on her folds and push forward, sliding my cock into her.

"Oh! Yessss, oh fuck yes!" Yang sighs as I penetrate her.

I bury my cock deep inside her pussy until my pelvis rests against her ass. I lean down and kiss Yang, our tongues swirling together as we moan into each other's mouths. We share a passionate kiss, my cock buried within Yang's warm, welcoming pussy.

"Your cock feels soooo good..." Yang moans.

I thrust my hips, fucking her pussy. It feels amazing to be in here again. The tightness of her pussy gripping my cock makes me want to cum right away, but I have to hold back.

"Mmph!" Yang moans, "Fuck me, fuck me! Fuck me hard! Ohhh!"

I continue pounding Yang's pussy, slamming my cock into her. I watch as her tits bounce up and down as I pound her.

"Mm!" Yang cries out, "God, fuck me! You feel so good inside me! So big and thick!"

I feel that I'm close but hold back. I want to make sure Yang cums first.

"Ohhhh! Yesss, yeeeees!" Yang cries out, "Harder! Harder, fuck me harder!"

I slam into her as hard as I can, feeling my balls slapping against her ass cheeks. Yang's pussy is so tight and warm. My cock is squishing inside her as I fuck her, causing sparks of pleasure to shoot through my body.

Then Yang grabs me and pulls me close until her lips are up against my ear.

"Let me tell you a secret," She whispers into my ear as she moans, "I'm not on birth control," She said and I can feel her grinning even though I can't see her face.

"Ohh..." I breathe, "Are you serious?"

"Yes~" Yang moaned, "Cum in my, give me and Blake a little surprise baby~"

Yang's words send me over the edge and I start to cum. I shout out loud as my cum erupts inside Yang, filling her womb with the seed of life.

"Ahhhhh!" Yang screams as she orgasms, too. The feeling of my cum filling her womb causes her to buck and shake, shuddering through her orgasm. I grunt as I empty everything I've got into Yang, feeling my cock pulsating within her pussy.

Yang lies there, panting, her chest heaving as she catches her breath, "That was hot... A whole lot of cum..."

She pulls me close and kisses me deeply, her tongue sliding against mine. I return the kiss, tasting the mixture of our sweaty bodies.

"Mmph~" Yang murmurs, "Mmmm..."

We break apart and just look at each other.

Yang looks down at the cum flowing out of her.

"I might actually get pregnant from this..." Yang says with a grin.

"Wait, you weren't joking when you said-"

"Nope, " Yang cuts me off. "Blake and I talked, and we agreed that we want your kid."

She then pushes me away from her, "Now go and impregnate Blake too."

"Really?" I ask, looking over at Blake who was sitting at the table next to Yang. At some point, she has already taken off her underwear and is sitting naked.

She smiles softly and nods, "Yes, Yang and I want to start a family. We want you to be the father of our child."

I smile back, "That would be an honor. I'm happy that you're both trusting me with such a huge responsibility."

Yang groaned, "Stop talking and fuck a baby into her already."

I laugh and pull Blake towards me, kissing her passionately. I slide my hands up her sides and grab her breasts, squeezing them. I push Blake onto the floor and lay atop her, pressing my cock against her pussy. The thought of fucking a baby into her already got me hard again.

"Mmm!" Blake moans softly, "You sure know how to treat a lady~"

I lean down and kiss her neck, nibbling on her skin as I rub my cock against her slit. I can hear Yang moaning behind us, watching us. I feel Blake tense up beneath me.

"Are you ready for this?" I whisper into her ear, "I'll be putting a baby into you soon."

Blake shivers, "Y-yeah..."

I push myself inside Blake, feeling her pussy stretch around my cock. Her warmth is incredible and it takes all of my willpower to keep from fucking her right away. But I have to pace myself, I want Blake to cum first.

"Mmph..." Blake moans softly, "Oh, god..."

I begin thrusting slowly inside her, feeling my cock sliding along her inner walls. I am so sensitive now, having just cum inside Yang, and the feeling of Blake's pussy around my cock is sending me wild. Every time I move inside her, her pussy squeezes my cock like a vice and sends pulses of pleasure through my body.

"Mm~" Blake moans as I continue to fuck her, my cock plunging deep inside her pussy.

I reach up and pinch one of Blake's nipples, rolling it between my fingers. She immediately arches her back and moans louder. I do the same thing to her other nipple and she continues moaning, "Oooh~!"

"Fuck..." I grunt, "You feel amazing..."

Blake moans and lifts her hips, pushing herself back onto my cock. She grinds her pelvis against me as I drive my cock deeper inside her, making her moan in pleasure.

"AHHH!" Blake cries out, her whole body tensing up, "Oh, fuck!"

Her orgasm takes her by surprise and she moans loudly, her eyes fluttering shut. Her pussy tightens around my cock and I feel her juices flow down my shaft, soaking my legs. I hold Blake tightly, moving slowly as she comes down from her orgasm.

"Mn..." Blake mumbles, "God, that felt good..."

My dick is still buried inside Blake's pussy and I haven't cum yet. So I decided to speed things up.

"Wait- I just came!" Blake gasps, "What are you doing?!"

"You can't get pregnant if I don't cum," I grin, "And I haven't cum yet."

"Oh god..." Blake bites her lip, "Just... Just hurry up."

"As you wish," I chuckle, kissing Blake on the cheek.

I roll over on top of Blake and pick her up, carrying her over to the table. She lets out a yelp and wraps her arms around my shoulders, clinging to me. I set her down on the edge of the table and she leans back, spreading her legs wide open. I push my cock inside her again, filling her up completely.

"Mm~" Blake moans, wrapping her legs around my waist.

I pull Blake closer to me and start thrusting again, slamming my cock into her. Blake holds tightly onto the edge of the table, biting her lower lip as I fuck her. I feel her heat around my cock and I start to lose control. I am about to blow my load.

"I'm gonna cum!" I shout, my voice cracking.

Blake mewls softly, her head tilted back. I grab hold of her thighs and slam my cock into her as fast as I can, trying to bury my dick deep inside her before I explode. My balls tighten and I feel the first spurt of hot cum erupt from my cock and shoot deep inside Blake's pussy.

"Ahhh!" Blake cries out, shuddering under me as her own orgasm hits her.

My cock twitches inside her pussy, pumping out thick ropes of cum that splashes into Blake's womb. I keep my dick balls deep inside as I empty my balls into Blake, my whole body trembling. When I finally stop cumming, I collapse on top of Blake, my cock still buried inside her.

"Well... That was fun," I pant, my breathing ragged. I look over at the couch and see that Ruby and Weiss are already soundly asleep in each other's arms. "We should do this again."

"You bet we will." Yang laughs. "It'll be a YangBang!"

Blake groans, "Seriously? You almost went the whole day without saying any stupid puns and you decide to do it now?"

I laugh, "It wouldn't be Yang if she wasn't making puns."
