Chapter 1 - Extra Measures

He was awake. He had no idea when he went to sleep, surely no idea when he stopped having dinner, nor the faintest memory of why he decided to cease enjoying the beefy noodles his precious Imouto went all out for. Beef is by no means normally a lavish dish, but the look of blissful excitement on her face when she was cooking meant the world to him. He would never have blown that off for a little extra sleep, or to rush somewhere without an emergency; like the house burning down, or Godzilla attacking again... So...Where were the noodles? The floral-print bowl, tarnished silver chopsticks, and her glowing smile? And where did this fog come from, clogging his head with fuzzy...Fuzziness...

It starts with a simple whisper of hot air steaming against his strangely cold groin, and quickly moves on, one little tap and tingle at a time. From the softest sensation of something far too pure brushing against him, to the suddenly much warmer embrace of a firm grip.

“Gua-” He finds himself gasping as the world finally begins to come into focus, memories of feeling exhausted mid meal arrive and the image of his Imouto’s smiling face as his eyes close for the last time is branded upon the back of his eye lids.

With a flourish he twists and pulls his hand towards his chest, only to feel it write a harsh rebuttal into his flesh, crushing and scraping itself against a foreign material he hardly remembers being at the kitchen table, let alone the comforting dream vessel he can faintly feel beneath him. Again he pulls, and again he fails, again and again and again until with a snap his wrist erupts into a cacophony of hot flairs and spasms that manage to hammer his ears. With another pleased grunt at the feeling on his groin, he opens his eyes to glance upon the restriction that has earned his utmost ire.

It is with this, that he sees the rope, cutting into his flesh and drawing a faint trace of blood. That rope appears to be attached to the frame of the bed, which….Isn’t his? The first clue being how pink it is, and the second being how much more comfortable it is. This would be concerning if he was allowed to feel more than two sensations at once in his current state. Those two sensations being the warmth between his legs and the fluff underneath him.

With this, and an almost pathetically paltry panic, he finally wills himself to glance down. In hindsight, he really didn’t need to use his eyes, to know what was going on.

His Imouto is the most adorable girl he has ever had the pleasure of helping raise. And the only, but that’s not the point! From her chocolate smooth hair to her adorable little button nose, to her angelically delicate green eyes which twinkle in the moonlight and brighten at the sight of him. He has always known she was a little too mesmerized by her big brother, but he figured it would pass. A loving sibling relationship is nothing to worry about, and most girls reach a stage where their sibling worship fades and them find themselves a fling or a stable of boyfriends to burn through within the next few years. This is basic knowledge any brother knows, and it is an expected formula any good and considerate sister should take note of so they can follow it with determination.

As far as he is concerned, with the sight of her delicate fingers wrapped around his rapidly stiffening cock, and the glow her eyes exude as she takes in his musk; Reika might just be the most inconsiderate, inconsistent, throw-the-whole-damn-book-away kind of Imouto ever contrived. Entire novels could be written about the sheer difference in her approach to dealing with the basic sexual tension any good siblings are bound to have. They would likely be more erotic than her in his vision, for whether his cock is in her hands or deep in her throat, she will always be his cute and innocent Imouto and therefore incapable of causing him arousal from any sort of sexual attraction towards her petite and unblemished princess-like body.

No, his increasingly hardening dick is simply a product of the constant warmth given off by his sister’s exploratory hand, and the sheer sexuality of the situation, and not at all because of how much any normal person who is not her brother would admire the lusty excitement on such an innocent girl’s countenance.

Her hands roam over his cock, playfully massaging the tip. He recognises the warning sign of boredom just in time to close his eyes, narrowly avoiding her wistful gaze at his face. “Huahhh…” She sounds, “this is boorrring..” He feels her tap her fingers up and down his cock, and she takes his balls into her other hand, caressing them with her thumb. “He should be awake by now… Oh well. Auuum~”

He opens his eyes just in time to watch the tip of his meat disappear into the confines of an even more wonderful warmth, his cock pressing against the soft cushion of her cheeks as she sucks, hungrily smothering it instantly.

If his penis were a mobster it would be lucky to survive in the vacuum his sister’s efforts provide for a minute, as is he considers himself lucky he manages to stifle his grunts to believable sleeping pleasure sounds. She swirls her tongue around, tapping up his precum with an innocent smile and a luxurious “Mmmmm.” As far as meals go, she is definitely enjoying this rather vile act more than fast food. He inwardly notes that such a fact would be extremely hot, if this was not his sister, who he is totally adverse to finding attractive in any way. The way her cheeks are pulled in and her hair falls over her shoulder brushing his balls and the way she is intently focused on pleasing him is not at all attractive, though it would surely be amazing with any other girl even half as aesthetically pleasing on the eyes as his sister.

Pausing to get her bearings, she begins to lower her head, slowly taking more and more of his stiff rod past her lips with the kind of playful expression he would expect in an arcade. In fact, the way she shifts back and forth just a little with every bit of new land obtained, he is given the distinct impression this is an incredibly pleasing game for her; one she is winning if the feelings beginning to build inside his balls is anything to go by. Oh how he wishes it was someone else’s tongue wrapping around him as his sister’s head begins to bob, anyone else would be fine. His ex-girlfriend could have come over for dinner and drugged him so she could have her way with him one last time- ooh that’s a good thought, he realizes, and begins to focus on it as she quickens.

The image of his ex is creepy but it is at least guilt free, and he happily uses it as his excuse not to hold back any longer. With that simple rule in place he finally allows his cock to further harden in preparation for his release, one he can feel beginning to build pressure rapidly. “Whuff did ish ghet arder?” She questions around his cock without bothering to pull up, and the pleasant humm of her voice resonates, shocking him out of his dream image just in time for his first spray to hit the back of her throat. Hers, Reika’s delicate little throat, sullied by his seed.

“Ooh-aaak!” In a show of supreme innocence that tells him without doubt that his is the first dick his sister has ever given the honor, she is completely caught unaware as his second and third string of cum floods her airway.

“Keh-k-” She begins to cough, as she removes him from her sweet confines, cum onto her chin and the hand she uses to cover her mouth with.

He’s actually kind of pleased this allows his fourth and fifth to splatter across her face and bangs, if only because his cum on her face makes the cursed image of his sister coughing up his seed a bit more surreal, a bit more dreamlike, and that makes it a bit hotter and a bit less disturbingly lacking.

His final glop lands on her nose, and another cough forces her forward, smearing it across her cheek with his cock. Still, despite it all, when she’s cleared her airway, she smiles blissfully. “Aww, I wasted so much…” She complains, despite housing an expression like a little girl told Santa is coming early just for her. She’s not that much younger than him, and yet… it truly surprises him how well that image sticks.

Especially if Santa’s emergency gift was to cover her in cum, given, well, she’s covered in his cum.

He closes his eyes again as he sees her gaze move upwards, and after a few moments he feels her let go of his cock entirely. The gentle sounds of shifting are clear, up until he feels a new heat. “Oh well, I’m done waiting, if he’s not up yet he’ll just have to wake up inside me!”

His eyes shoot open as he feels the tip of his cock split her entrance and the angelic warmth of his sister’s virgin cock holder wraps around him in a way unlike anything he’s ever experienced. His previous girlfriend’s body pales in comparison and that is not sibling bias! His sister’s baby canal is a definitive no go zone for him! In fact, he finds himself losing his composure and pulling against his bindings for the first time since his awakening. Was it just moments ago? It feels like a battlefield ago.

“What are you doing?” He demands suddenly in an attempt to startle her off of him. This is rape after-all, an action that could and would forever shatter the sibling relationship she so clearly holds very dear to her heart.

Or so he thinks. “Oh?” She chuckles, innocent smile turning to a devious smirk in an instant. “Were you awake for that?” She asks. He tries to school his features into pure anger and shock but no one can read a brother like a sister, and this sister pays far too much attention to her brother. “Did you enjoy that?” She asks. “Having your cock deep in my mouth? Hehe-I bet you did.”

Before he can reply he feels himself push past her outer lips, devouring him past the tip with a gleeful roll of her hips.

“Uha-please.” He begs, “stop, this is your first time right? It should be with someone else, anyone else, maybe- maybe someone who finds you attractive-”

She cuts him off, grinding his member deeper into the Forbidden Realm. He has to stop, he can’t talk, or he’ll give her the child she was born to carry. “Did you enjoy watching me choke on your cum?” She asks, reaching up to frame her face and show off her covered hand by smearing more across her cheek. “I bet you did, hehe-just like I bet you’re gonna enjoy watching something else choke on it.” She taps a spot on her skin just below her stomach. 

“Not talking?” She asks, grinding him further and further. He can feel the ridges inside her pressing against him, and her walls stretching to contain their new best friend.

She continues to lower herself with a raw need that lacks any before seen grace. “My first time should be with someone I love, Onii-san.” She says confidently. “And you can deny how hard your Imouto’s body is making you right now, but you can’t pretend you don’t love me.”

He finally feels the end of his throbbing length kiss the final wall within her, and her cute little butt finally rests on his legs. “Can you?” She asks. “Can you look your Imouto in the eye and tell her you don’t love her, Onii-san?” She asks, her piercing gaze locking onto his. “I’ll never forgive you if you lie, never.”

A moment - an eternity - passes where he tries to speak, and finds himself without air. He tries to push her away, but he can’t. With a few simple words he finds himself unable to do anything to stop the inevitable.

“Just stop.” He asks, his eyes pleading. “If you love me you’ll stop.”

She pauses, for just a moment, before an honest laugh wracks her frame, shaking her insides around him as she leans forward and places a wet kiss on his chee. “Come on Onii-san, you know I’m not gonna give up after coming this far, your stern gaze makes my heart waver and sing too much. My love for you is why I can’t stop, I’m sorry but I’m not sorry.”

A moment passes as she begins to grind herself into him, back and forth and side to side, her captured prey stretching her pleasure pocket with every twitch. Her cum covered hand lowers itself to grasp onto her exposed clitoris, apparently someone managed to teach her how wonderful that is, if the urgent feeling on his cock as her pussy spasms is anything to be believed.

“Can I have a kiss?” She asks politely, and is not at all discouraged as he shakes his head with a frown.

Her pace suddenly, remorselessly quickens, her ass slapping against his balls as she shifts just a little up before allowing him to bottom out inside her again and again.

“Please? Just one?” She pleads and he is already shaking his head, eyes tightly closed in a concentrated effort to stop the coming release.

“You know you’re not gonna get to cum until I get my kiss.” She teases, and still he refuses.

She shakes and grinds and bounces, the pace changing incredibly as the tip of his cock slams against her cervix again and again and again.

With a shiver and a shake the unbelievably tight insides of his only sibling tighten and spasm. “Oh fuck yes fuck-yeeeee~”

Despite his protest, something powerful stirs inside him. His cock thrums in warning.. Somehow, she knows. She knows how badly he wants this, how desperately he yearns to fill her womb. And despite her own ecstasy, she halts, just in time. “I gave you a blowjob for a reason.” She declares. “So that I would know when. You’re, not, cumming, until I get my kiss!”

Her eyes are a bit crazed he realizes, with a gasp and a gulp, as he bucks into her on his own for the first time- only to have his legs forced down and stopped by her knees. “No! Give me my kiss!”

With the urgency of a snail, he denies her, clamping his lips shut and refusing to even give her the dignity of a response.

Slowly, things calm down, he gives a little whine as he feels his substance crawl back into him. He honestly begins to believe it’s over-and just then she starts again. Rapidly, she starts to bounce, smothering his girth in her juices and filling their air with blissful breaths and sighs of perfection.

He grips his restraints tightly, desiring nothing more than to break free and grab her ass so he can pound into her. No onii-san could resist at this point even if it was their beloved Imouto, no matter how good a brother you are, no matter how much you understand the attraction gap between family and other, there comes a point where you need to cum and her new found torture method is rapidly pushing him past that point and into a new territory; a terrifying place where the rules no longer apply.

Just as before she stops as she feels him begin to twitch and just as before she leans down and tests the barrier of his lips but this time… This time, he gives her what she wants. After all, she’s his precious Imouto. Surely, she’ll give him what he wants?

His lips spark and his mind delves deeper into the endless fog at the triggered gratification. As if a seal is broken and suddenly even this kiss seems pure and right.

He enters nirvana, as she begins to move again, there is no other way to describe it. The golden gates of sunshine brighten up all previous hesitations with a purity that renders any other decisions on this issue moot, that is until her knees dig into his legs again and she stops him at the edge of orgasm for the third time.

“Grrr-Reika what the fuck.” He growls, and he doesn’t even feel regret when she flinches.

“Just one more thing Onii-san.” She says, quickly and coyly pushing her distress into its own little cave of which he will never see again. “I need you to beg.”

“Beg?” He asks.

“You’re not gonna let me do this again, are you Onii-san?” She asks. And he allows her a nod, of course he’s not, this is rape, and that would be insane. In fact this is the last damn time he ever eats anything she cooks ever again if it is the only thing he swears for the rest of his life, this will not occur a second time. “I want to look back on this and remember the time you begged me to let you cum inside me.” She pleads with eyes like that of a mourning kitten. “Please?”

“Do I have a choice?” he asks, smiling just the barest amount. She shakes her head negative.

“And you promise you won’t do this again if I do?” he asks.

She nods.

“Please, my beautiful imouto-chan.. Can I cum?”

It should be enough he wagers, she is always after his approval and never before has he given it out so freely. So he is admirably quite shocked by the confounding event of her scoff. “No you idiot. Please, my beautiful and smart and lovely Imouto-chan.” She scolds.

“Please?” He asks, attempting to thrust again and finding himself very surprised that she doesn’t stop him. He ponders if despite her words she’d let him deny her like this. If she’d allow him to bring himself to release without another word.“My beautiful and smart… And unbelievably lovely Imouto-chan.”

“Perfect.” her eyes light up with love and she begins to bounce again. Despite that, he finds the filling well within him leaves him no choice but to end it politely for her, just this once.

“Please, my beautiful and smart and lovely Imouto-chan,” he gasps as he takes on a new rhythm, matching her bounces with thrusts of his own now that she’s letting him. He can feel his balls swell, and the dragon’s package begin to flood, she made a mistake, and there is no way she could stop him now no matter what she did. “May I please cum inside your perfect pussy?” Even still, he finishes it, for her. Because she’s right, he can’t look her in the eyes and tell her he doesn’t love her.

“Yes, please!” She screams as she wraps her arms around him and her tongue invades his lips again. This time he kisses back, giving into her as his cock throbs again, greedily slamming into her in anticipation it is going to send into her.

Her insides tighten, her walls clamp and her cervix flutters in preparation to steal every glob of his cum it can as he rocks her through one orgasm and into the next. With one final earth shattering thrust his cum shatters the final dam within him. Rope after rope fills her confines in an instant, more than he had ever thought possible coming to the forefront of their lovemaking in the final moments where true bliss is realized and reality becomes a shadow lost in memory.

While he would never admit it out loud, his sister’s womb was clearly made to receive his seed, and that fact is enough to make him pump into her even harder.

For easily a minute, they lay in glow together, his arms instinctively trying to wrap around her only to be foiled by the restraints. “You did it.” Her voice cracks, and he gives her a slightly mournful smile as tears of unbidden joy drip onto him from her enchanting eyes. “You filled me up.”

“I did.” He agrees. “I didn’t really have much of a choice.”

“Shut up, you begged.” She laughs with a purity he would kill to find anywhere else. “You begged to knock your Imouto up.”

He gulps. “Kn-knock?” As she sways her ass side to side, stretching her pussy with cock, he can’t help but realize the possibility never occurred to him. Of course she was on the pill, she had to be, she has perfect grades, she has a life plan picked out, he helped her do it he was there he knows she has one!

“Mmhmm.” She agrees. “I’m ovulating.” With those simple words and another peck on his lips, she seals his fate. “Right now the rare and illustrious Onii-san sperm is hunting the much rarer Imouto egg. Secretly, just between you and me? I hope it’s twins, I would love twins.”

“You-you can’t, but-”

“Shhh.” She kisses him again, “please. Just lay back and enjoy this.”

“This?” He can’t help but feel a little strangled all things considered. And with a start she straightens herself and begins to pump his cock deep into her again

“Well yeah, I have to make sure don’t I?”


A lot of things changed after that day. Explaining to his mostly absentee parents why their daughter is clearly pregnant when he is the only boy in her life was, awkward, but he managed to put it off a while. They seriously believed he was just feeding her too much for the first couple months, which was a life saver since it allowed him to finish his midterms before the yelling started… They’re mostly okay with it now.

Probably the hardest part was not throwing Reika under the damn bus, having to lie through his teeth about how he totally wasn’t raped by his sister while she said things like ‘he begged to cum inside with this big dopey smile on his face’ created the kind of scene he is sure deserves its place in that novel right alongside the psych-eval.

It's gotten to the point where the whole family knows, but… At least his friends don’t, he wagers. They never see his sister, always preferring to hang out at their houses or this park, it suits him just fine. They’re proud brother’s themselves, after-all, he can only imagine how they would react to finding out how he broke the code and became abnormal.

“Hey, since you’re getting one, do you mind grabbing me a cherry from the vending machine?” One of his friends asks, an older friend from middle school. Normally he would laugh and tell him to get it himself but…

“Yeah, sure.” He takes the money with a smile. Reika learned how to properly mix fruit in pancakes today, and it was completely delicious, everyone deserves a reward.

The vending machines here are a little larger than they probably should be for what they house, but he’s never paid it too much mind. Just another quirk of a park that has been remodeled like ten times.

He pushes the money in, ordering the cherry.

With a few sounds of latches and slides opening, the cherry deposits itself into his outstretched hand.

One down, he pushes his own money in, presses the combination button for his own drink. Slide, latch, metal whirr- the front of the machine snaps open with a bang, wet spray from the fluid all over the drinks soaking his hair within an instant, and then before he even has time to react something rams into his chest and forces him to the ground.

The air is kicked out of his lungs, his eyes blur, and his lips are captured. The sweet taste of watermelon, he knows this lipstick, Reika’s started using it recently to catch him off guard. “I couldn’t wait for you to get home Onii-san our baby was lonely!”

He looks around, as reality catches up.

Huh, he thinks, apparently he was right, they didn’t know.
Great.


Class life hasn’t changed at least, he decides as he arrives in his off period English elective. Rumors spread every day, no one knows nor cares what goes on in his life, and for that he is forever thankful.

It is with the utmost relief that he waves to his teacher as he enters the mostly full teacher, and a dream like valor in which he strides to his desk - only to blink as he arrives and sees a familiar form already taking his seat. “Our baby moved Onii-san! I had to come tell you right away!”

Ahh, uhhh…. “Gaah!”


With a sigh he arrives home from school, kicks off his shoes as he has no need to be reminded, and makes his way to the kitchen to make his sister lunch.

“Oh yeah I love the way it stretches me, and how it gets real angry like when it’s about to cum, aah, just thinking about it makes me wanna jump on him and bounce until I get pregnant again!”

“You can’t get double pregnant.” He sighs as he takes the chicken out of the fridge - wait. “Who are you even talking to?”

“Oh, you’re back!” She laughs, “Leyla.”

“Aah, huh… My… ex?” His brow twitches.

“Yeah, she was calling because she’s back in town and wanted to catch up so I filled her in.. Also, totally unrelated but what do you think of a threesome?”

“I’m not having a threesome with my ex and my sister.” he deadpans.

“It’ll be wicked fun! Don’t you want the baby to have lots of cool stories!?”

“That doesn’t even make sense!”
