For the current problem my solution dips into the realm of silliness but I think is doable and maintains the fantasy as well as the law.
.... Blah blah blah build up,
Looking into your beautiful Water Princess's wavering <PC starting Eye Color> eyes, you can feel her determination, her immense love and respect for you, even her lilting anxiety as she nervously awaits your answer. You make your decision.
<Yes: Sex her or whatever, she came out of your ass its not like your really related>
You cup her cheek, her pale flesh <the same shade as yours> <a stark contrast to your own PCSKIN >. Closing her eyes she nuzzles into your hand, dipping down and tilting her small face upwards to meet your own, you move to give her what she so desires, your affirmation and acceptance of everything she is. Sensing your decision your other daughters hoot and holler, gathering around the two of you smiling and giggling with glee. Their hands wrap around your <PCTHICKNESS> frame gently pushing the two of you together, no doubt just as eager for their turn. As the two of you get closer, you watch your eldest with a warm heart, her eyes half lidded she looks lost in a dream, lips curling upwards into a smile that you've come to adore more than anything, and just as your lips are about to touch...
A massive explosion erupts from the far side of the chamber and bright blinding light floods the darkness around you!
Instinctively your arms fly out and clutch your eldest close to you as you both are all forced to the ground by the shock of the blast. Your daughters scream and cry out in pain, <IF: PCNOTBLIND> and you as well for that matter, as the light shatters the comforting darkness around you, bathing your visions' in piercing, burning white. Your <eyes> <senses> recover first from the change in environment and you look around blearily for your attackers and shouting the names of your daughters. Blind and disoriented your daughters instinctively hurry towards the water, that is except your eldest who still clutches tightly to your chest.
"Daddy! What's going on!"
You'd like to know that yourself. Confident your daughters will be safe on their own if they can get to the water, you hold your eldest closer to your chest and reach for your <PCWEAPON> and look to the source of the explosion. A large hole has opened up in the side of the chamber, smoke and debris cling to the air around it heavily and shadowy figures with red glowing eyes poor in through the concealing fog unhindered at all by the water beneath them, running across it as if they were servants of the One themselves.
"Black Void!" You curse to yourself, dread welling up into your stomach. If your years as a <PCCLASS> have taught you anything they're the only group both crazy enough to attack a station like Tavros and well equipped enough to afford STID boots.
(Surface Tension Ion Distortion boots: Downward force forces ions of any liquid or suitably dense gas into a low density but highly rigid solid held in place by a metastable electrical "freezing" of atoms in a localized area around the users feet. The boots are not powerful enough to walk on air but they can certainly walk on water and the dense gases of Jupiter without a problem. Due to harnessing the solidifying effect of their special brand of science magic the boots are virtually indestructible and perfect insulators, so long as their users keep moving that is. The boots have gained particular favor in research, allowing environmental scientists to approach the mouths of active volcanoes on foot, and in cinema for allowing actors to play out scenes, like running across active lava fields in Termineuter XXII or riding tidal waves without a board in Soul Surfer III, with minimal special effects. The boots are exceedingly expensive however and are prohibited for use in combat as a single kick has the ability to flash freeze an organics entire circulatory system. The inventor, Kanen K Reaper, is credited for discovering the 24th form of crystalized ice in the process of these boots inception.)
"W- what's black void!?" Your daughter looks up at you with wide fearful eyes, watching your fierce and dark expression, I side of you she's doubtless never seen before. You glance down at her. You would sooner rot in hell than let your beloved daughters be taken as slaves or worse by the scum of the galaxy. But... Watching more and more of the figures rush in, surrounding you and your eldest, these must be dozens of them, no... at least a hundred of them pouring through the massive opening in the wall. Just as you are about to ready yourself for a fight to the death and thinking of the last words you will say to oldest child. A figure emerges from the cloud of dust cursing and coughing and waving its hand in the air.
"Ugh, dear god, and I told Isabell not to use so much C4!" A feminine figure immerges from the dust, clad all in white with bright blue accents doing their best, and failing, to disguise the generous natural curves of her frame. The woman, no... young woman looks to be somewhere in her late teens or early twenties. Her long hair shines like black silk even in the dissipating smoke and is pulled into a tight ponytail that frames the subtle shapes of her angular face quite nicely. Her hair ends just before the pleated curve of her ass. Her immaculate uniform somehow unstained with dust ends at a skirt cut just above her knees. Black stockings take up their torch and hug wide hips, supple thighs, and long legs down to the knifelike points of her black heels. She would almost seem a cool beauty if she weren't on her knees in front of you coughing up a storm.
You notice two curved swords sheathed at her hip and what looks like a fully equipped police utility belt hugging her waist. UGC? She couldn't possibly be...
Too stunned to speak your daughter opens her mouth for you.
"U- uhm..." She reaches hesitantly for her shoulder, "Are you alright miss...?"
The young woman's blue eyes snap open and she takes a deep gasp of air. In the next instant she's holding your daughters hand causing her to squeak in surprise and press closer to you. Her own hand is gloved in sheer white fabric, she kneels before your daughter on one knee, head bowed, like a prince before a princess, you'd laugh at the irony if your weren't so shocked. You didn't even see her move. A stray thought burns increasingly present in the front of your mind as your eye is drawn to the curve of one of her swords where the ominous name Aegisbane is inscribed. With that speed... A wrong move here might cost you your life.
"Alright? I couldn't possibly be better my dear," She raises her head and grins widely at the young girl, her eyes lid and... flash a light shade of purple? Did you see that right? A trick of the light perhaps... The young woman you deem is much too close to your daughter at the moment, but you hold your tongue as you watch her shifting left hand cautiously, tensing to block anything she might do. With a quick flick of her wrist she produces an immaculate, small, and pure white flower. It's a lily! How did she do that!? You were watching her hand the whole time! She offers the flower to your daughter, "My day has been infinitely brightened with appearance of such a radiant flower like yourself." She presses the flower into your daughters hand.
Your daughter, despite her confusion, blushes a deep purple and her incandescent hair glimmers with sudden color. "W- what? Me!? N- no way my sisters are way more..! I'm not..." She presses herself closer to you hiding her exposed nipples with your body, clutching the flower, suddenly aware of her own immodesty she hides her face and mumbles into your chest, "O- only daddy's ever said things like that to me..."
Unable to stand silence any longer you bark at the intruder. What's the deal? Who are you people? What do you want!? You just blew a hole in a multimillion credit nursery and more importantly are interrupting some very important family bonding!
She turns and glowers at you, the picture of total disinterest, "Eh? Who the hell are you?" Dumbstruck, before you can think of a response, a thick black book slams vertically and heavily into the young woman's head.
"Augh!" She screams in agony and rolls around on the ground in front of you clutching at her skull, "Iitatatatatatatatata! It hurts!"
The assailant, to your surprise, stands right next to you, a woman in identical garb as the one on the floor plus body armor, a gas mask with red glowing goggles, and a massive black book tucked underneath her arm. What is up with these people being able to sneak up on you! You didn't see her coming at all! A voice comes from the mask, a deep and heavily electronic bass, "I'm terribly sorry about our ill mannered captain mister Steele."
From behind her you notice the rest of the intruders, now that the smoke has cleared and your eyes have adjusted; scores of other women dressed the same as the one before you stand on the water in a massive semicircle surrounding the Island. Each one stands at the ready, armed with massive laser rifles. You don't recognize their make, but you can recognize what's going to hurt.
Uh...
"Ah, how rude of me." You eye them cautiously but bring your attention back to the woman in front of you as you hear a hiss of air and a soft click as she pulls off her gas mask with her free hand, revealing the young woman's attractive if stern face. Her shoulder length brown hair is pulled into a tight bun, which she promptly undoes and shakes out to its full length. Shoving her gas mask onto the unassuming head of the woozily rising captain, backwards. She screams, her voice distorted by the mask, and falls backwards.
"Uhh... lets see..." Taking the massive tome in hand she opens it and flips to a bookmarked page, "Ah right... I should answer your questions," She stares blankly at the text like she's reading a manual. She's kind of... Ditzy? Isn't she... Her piercing brown eyes meet yours and she points to herself, "I'm Ria and that..." she gestures to the woman struggling with the helmet attached to her face. It pops off her head and she gasps for glorious air, "is Captain Itsuki."
Captain Itsuki meets your gazes for a brief second before collecting herself, rising to her feet and dusting herself off. She clears her throat and takes a deep breath. Her blue eyes snap open and she points to you and your cowering daughter imperiously. "That's right, thank you lieutenant! And you! You Mister Steele are in big trouble!"
What? Why?
"For defiling delicate flowers!" the captain snaps back immediately. Ria punches her in the face and it seems to be the brain duster she needed. After the initial crack her head swivels back into place and she visibly relaxes, "Ah... thank you for that Ria, I needed that." She turns to you again and bows her head, "My apologies for that Mr. Steele, you're daughters are quite breathtaking. <brute speech: You grunt your agreement, no shit they're hot, just look at who they came from.> Captain Ituski covers her mouth and clears her throat hiding a blush. "R- right, in any event..." She fixes you with a stern gaze, bringing her arm forward, presenting a blue armband, intricately woven with white and orange accents. She points to the symbol emblazoned in the center; something like an orange P crossed with an @ symbol.
"We," The captain begins gesturing to herself and the women behind her, "are the dedicated servants of Queen Pandora. Second only to the One, her authority governs all virtue in this galaxy and the known universe." Your eyes widen, now THAT'S, a bold claim. "You," She continues, "Have been found guilty of a grave sin you have yet to commit." Your brow furrows. Excuse me? "Read <him, her, them> <his, her, their> charges." the woman proclaims to her lieutenant.
"Yes captain." Ria turns to the next page in her big black book, stone-faced as ever she begins reading your apparent 'charges,' "<PCNAME> Steele, you stand accused of corrupting the mind of a pivotal nexus of new content, this offense, if allowed to continue, based on interdimensional law, could destroy the very fabric and even funding of our reality. What say you in your defense?" She stops reading and looks up at you, awaiting your response.
<Uh.... What?> <Wincest FTWx2> <Sorry?> <Fight!>
All choices end in the following except fight which leads to instant death.
Ria pauses, closes her eyes, and tilts her head to the side as if contemplating your response.
"Hmmm," she begins after a moment, "Your response has been deemed inadequate, by order of our master, her executioner will now carry out your destruction for the good of this reality." Captain Itsuki nods solemnly and steps towards you. Your eyes widen, looks like you'll be fighting your way out of this one after all...
"W- wait!" Your daughter pushes herself off your chest and looks back at your would be executioner with wide frightened eyes, the white flower still clutched to her breast. "Executioner!? That means your trying to kill <him>! But why!? <Daddy> hasn't done anything wrong!"
The captain smiles sadly at her, "I'm sorry young one, the verdict is final..." Your daughter however bristles at that and pushes you away from her. The strength in her arms surprises you, pushing you off her carapace with gentle ease. You stumble backwards surprised. Your daughter rises to her full height, towering over you and the captain. Itsuki takes a cautionary step backwards. "I am not... Some youngling anymore!" Surging forward, before you can stop her, she strikes at captain Itsuki with one massive claw. The surprised captain jumps backwards just in time as the powerful limb of your daughter's lower body crashes into the earth before her sending chunks of rocks and everywhere. "I'm an adult and I love my <dad>! If there's anything corrupt about that then I'm the one at fault! If you want to get to him you'll have to start with me!"
You can’t help but feel a giant surge of pride at her actions, the strength of her frame and the bold defiance she exhibits, love swells your heart for the beautiful and independent woman in front of you. You ready your <PCWEAPON> to join her in the fray.
"If only you knew how right you are..." The cool voice of the captain sends chills down your spine and stop you and your daughter dead in your tracks. You look up at her horrified, unfazed at all by your attack and slipping through your guards in an instant. Itsuki stands on the carapace of your wide eyed daughter, back to back, just behind where her human form meets shell. "But you're still far too young to take on someone like me." With a strike you can barely follow with your eye she hits the bewildered girl in the back of her neck. Her eyes roll back and she loses consciousness, dropping to her knees with a ground shaking thud. At seeing her harmed, a feral roar rips through your lips, and before you know it your charging full bore at the woman standing above your daughter.
"Stop." Ria's voice halts the captain in her tracks.
It was over in an instant. You're lying prone on your back staring up at the ceiling in confusion. Her heel digs into the ground by your head and her soft ass has found its home on your <CHESTTONE, BREASTSIZE> chest. Her haunting eyes are fully dilated and sharp with killing intent the blade of her sword a mere hairs breadth from your throat. The incessant beeping of your shields alerting you to their failure. Her eyes gradually soften and she turns from staring blankly into yours to narrowing them on her lieutenant. "What was that?" She asks her.
"His case has been reevaluated," Ria responds, "and a different punishment has been issued."
She stares at her blankly, not fully understanding, "What do you mean? What punishment?"
"Transfer."
"Transfer!?" Itsuki yelps and jumps up in sudden shock, probably less to do with the new 'punishment' and more to do with you reaching up and suddenly groping the perfect globes of her stocking covered ass. She's got a surprisingly soft hinny for how fast she moves and you let her know as much. She stares daggers down at you her free hand pressed guardingly on the back of her skirt. Joy in defeat as well as victory, your adventures have taught you that much. The slight blush coloring her face is quite becoming and you want for more. For such a virtuous woman to wear such a flattering black and lacy thong... molding so closely to the petals of her own pretty little flower to punish someone else for corrupting the minds of innocents... You watch with glee as the blush spreads further and further across her panicked face with every one of your words. Her long legs stiffen in place as she bigs to shake. You fold your arms behind your head and politely ask her how much longer she plans to straddle your face, you much prefer she take a seat. The young woman's brain overloads and a feminine squeal erupts from her lips as she jumps nearly ten feet away from you. Crouching down to her knees, her sword clatters to the ground, and she desperately clutches at the hem of her skirt, every inch of her beat red and shivering. "L -Lines! So I don't have lines in my stockings!" She points a shaking finger at you, turning to her lieutenant in visible distress, "W- what do you mean Transfer Ria! H -he's a dangerous criminal! A pervert! He tried to screw his own daughter for Christ sake!"
Ria shakes her head in dismissal, "I only relay the orders captain... besides," she looks to where you are now, having found your chance you've rushed over to your unconscious daughters side and are gently trying to coax her awake. "I don't think letting him live would be the worst idea, from here he just seems a caring, doting parent."
Itsuki stops shaking and looks over to you and your daughter, sensing her gaze on your back you meet it cautiously. She holds your stare for a long while, searching your expression for something, finally she lets out a long sigh and hangs her head defeatedly. "Fine..." She stands back up and retrieves her sword, sheathing it as you eye her cautiously, holding your unconscious water princess close to your chest protectively. "No need to look at me like that Mister Steele, I no longer have any reason to attack you, and rest assured your daughter is perfectly fine, she should wake up any minute."
You ask the obvious question, what did she mean by transfer. She nods, "Right... Ria." The Lieutenant turns to you and shoulders her explanation, "A transfer refers to the inter dimensional temporal swapping of two troubled individuals." A what? "In layman's terms," the Captain continues tiredly, ready to be done with this whole ordeal, "We'll transfer your character data into a different save file and vice versa. No matter what we can't allow incest with a persistent NPC in this reality, such is the law of our creators. However..." she points to the two of you, "Seeing as your relationship is not apparently malicious our master has deemed it necessary to keep you alive, thus if you are to continue with this disgusting process, a transfer is the only option if we are to see the nexus gain more content."
You know you should be understanding this on some deeper level but all of this is just sailing over your head. She sighs again, "We will be swapping with a Steele from a different universe. That Steele will have completely different genetic code from yours, and though everything else will remain the same, your choices, your companions, your experience, the daughter your holding won't be related to you though she'll certainly think she is and you can certainly pretend that you are. By all means forget you even experienced this. Just promise me one thing... No matter what 'things' you end up doing together love your 'new' daughters just as much as these ones."
You nod slowly. You don't understand any of this but you feel compelled by some unseen force to agree to this all the same.
Itsuki claps her hands together, "Alright, great, case closed, I hope we never meet again." Retrieving a bell from her pocket she holds it up and rings it. All at once a massive wave of vertigo hits you and you clutch your daughter tighter. "Another job well done Captain." Says Ria as your reality swims, "Oh stuff it Ria." Replies Itsuki. A flash of light seems to split open your consciousness as the secrets of the universe are revealed to you; the truth behind nine eleven, the answer of whether or not water is wet, every Snapple cap Snapple fact, you stare into the eyes of your creator and your controller through pixelated screens, you surf the fenoxo forums skirting the edge of your universe and all others, and, for a brief moment, you pass yourself and something different entirely each of his flags switched and his code symmetrical yet asymptotic to yours in every value and every bit. Then just as soon as it starts it ends. Itsuki's bell chimes a second time. You crash back into your body and in your arms is your Water Princess just where you left her.
Her eyes flutter open and warm smile spreads across her lips, "Hi daddy, how are you?" Her <PCSTARTINGEYECOLOR> eyes veritably glow in the dim light with love. You frown, but you thought... A happy coincidence maybe? You look around confused, where did the others go? "Is something the matter daddy? Another of your princesses asks from behind you, wrapping her arms and your shoulders. You start to answer but don't think of what to say, instead settling on a, "no everything's fine." "That's good..." She hums contentedly and presses closer into you. Did you dream it all? In fact what was it that you were doing? It seemed so important but the memory is getting foggy, like something in the back of your head is deleting the files. Your eldest pulls you closer, not about to hand you over so easily to her sisters just yet. Ah whatever... You've got fucking to do.
