Man Flu 6: The Brother's Sister (Reader Plus Bonus) (Patreon)

Seating my tight N95 mask just right to stop the fogging of my thick spectacles as well as ensuring that I was protected against the virus dwelling inside of the house I stood in front of I clutch the red binder that I had brought with me to my chest then take a deep muggy breath. Closing my eyes I run through what I was going to say for the dozenth time since I stepped out of my car and I remind myself, again, that I was doing this for him just as much as myself. Not that he would approve of what I was about to attempt. In fact, I knew that he wouldn’t. I was risking everything by being here right now. If what I said and did here today reached my boyfriend’s ears…well, I’d rather not dwell on that. All I could do in that case is beg his forgiveness and hope our love could carry us through. But I had weighed the pros and cons and come to the logical conclusion that the potential reward outweighed the risk. I simply could not let this opportunity slip me by without at least trying.

After another deep breath I open my eyes again and whisper to myself. “This is just business. It is nothing personal.” I sigh. “And he said it himself, there is nothing more important than this.”

Summoning my courage I press the doorbell. As I hear the chime ring inside the home my heart starts to race and a nervous sweat rises across my whole body.

“Coming!” Sings a slightly winded voice as the thump, thump, thump of running feet approaches the door.

Preparing myself I stand erect and straighten my round spectacles. With minimal make up on, my wavy shoulder length auburn hair held out of my face with simple bobby pins, and in an outfit of a calf length gray and black tweed skirt, white collared shirt, and pale yellow button up cardigan I was as drab as I could make myself. Not that it was far off from my usual geeky fashion sense but today I tried to look extra bland so that I didn’t give the wrong impression on my purely pragmatic intentions here. Of course, compared to her I didn’t need to bother. Compared to her goddess proportions my plump little body looked plain at the best of times.

The door suddenly swings open and there stands my boyfriend’s stunning twin sister. Nearly as tall as he was she had the same sunflower blond hair, the same piercing hazel eyes, and the same striking Slavic features just with hers tilted feminine instead of masculine. Combined with her natural good looks were the rewards of a life dedicated to physical fitness. Her physique was long and lean with the graceful muscular contours of some male fantasy superheroine. Currently in a blue sports bra snug across her high round breasts and skin tight blue leggings clinging to her powerful legs her firm, sculpted figure was on full display. Well, not quite full display with the mismatched pair of gray sweat shorts covering her crotch. I knew from experience that she didn’t usually wear those shorts with this outfit and I also knew why she chose to wear them to answer the door today. It was the reason that I was here.

“Fern!” Her gorgeous features light up as she sees me standing at her front door. She was a jock and I was a geek, but for some reason she’d always liked me.

“Good morning, Scarlett.” I give her a polite nod of my head. She was sweating and breathing heavy, her exposed abs tightening to perfect definition on her exhales. These factors combined the stray strands of hair that had escaped her long ponytail told me that she’d been exerting herself just moment ago. “You shouldn’t be working out right now. You’re sick.”

“Bah.” She waves off my concern. “I got the shot. It’s just a bit of a headache is all.”

“Still.” I say. “You should rest and look after yourself until the Man Flu has fully run its course.”

“Gimme a break.” She scoffs. “I’m already technically in quarantine. Now you want me to just sit here and do nothing? The city crossfit games are in two weeks. I don’t have time to be sick now.” Tilting her head she turns the friendly concern back on me. “Speaking of quarantine, you’re not supposed to be here right now.”

“Er, yes.” I say. “But…this couldn’t wait I’m afraid.”

“You couldn’t call?”

“No. I couldn’t.” I reply and pat the binder. “I’ve come to present a proposition to you. And it had to be done in person.”

She looks at my binder and the serious expression on my face and chuckles. “A proposition? For me?”

“Mmm.” I nod.

“You’re serious?”

“Yes, I am.”

“Now?”

“It must be now. Now or never.”

“If this is some sort of pyramid scheme thing…”

“Oh no.” I shake my head. “No money is involved. Nothing like that?”

“What are you and my chucklehead brother up to?”

“Stephen has nothing to do with this.” I say. “Well…I mean, it was technically his idea. Not that he realized it.”

She laughs and shakes her head. “What are you on about, Fern?”

“May I come in and give you my presentation?” I ask. “It will all make sense once you let me explain.”

“Well…yeah. Of course.” She steps aside and welcomes me inside. “Come on in.” I slip out of my shoes and follow her into her dining room. “Can I get you a drink or something.”

“I’d rather just get through this.” I say, my nerves rising. “If that’s okay?”

“Yeah. Whatever you want.” She sits down and motions for me to sit across from her.

I stay standing instead. “Before we begin I must ask you not to breath a word of what I am about to say to anybody outside of this room.” After a tense pause I add softly. “Especially your brother.”

Her eyes narrow as she tries to figure out where this was going. “Stevie doesn’t even know you’re here, does he?”

“Mmm.” I shake my head no. “He’s at work right now.”

“What are you up to, Fern?” She says, no longer chuckling. “All this mystery. And you’re so serious. What’s going on?”

“I would very much like to tell you.” I say. “But I need you to promise me first. Please.”

“Yeah. Sure.”

“No matter what you hear, you must promise not to repeat it. Ever.”

“Yeah.” She nods. “I got it. I won’t say a word. That’s a promise.”

I take a deep breath and let it out in a huff. “Thank you.”

Placing the red binder on the table in front of her I open the cover to reveal the first page filled top to bottom with facts, figures and helpful graphs and set into the presentation that I’d rehearsed so diligently.

In one smooth, nonstop go I lay out my case for her and I to have sex with each other. Backed up at every step by the latest research I give her a thorough education on male virility, female fertility, and the myriad biological, societal, and psychological challenges of procreation faced by modern humans. With documentation for everything I reveal to her how that after the age of 25 a woman’s chances of a successful pregnancy slowly but steadily wanes by the year until 35 when the odds begin to drop precipitously. I show her the past three years of data regarding my menstrual cycle and the good evidence I had that my monthly 6 day fertility window was currently on day 2. By a fortunate coincidence Scarlett was also on day 2 of 7 of her one time window of virility granted by the virus, assuming she wasn’t one of the unlucky women whose symptoms became permanent. In detail I show her Stephen and I’s mating schedule and go through the reasons behind the times and positions. I then tell her about the results at the fertility clinic from last year and explain the numbers regarding Stephen’s low sperm count and low sperm motility. I tell her about some of the alternatives that he and I might pursue, if not for his stubborn insistence that we do it the ‘natural’ way. I then assure her that there was nothing wrong on my end and that I have done everything that I could to have to maximize my chances through diet, supplements, prenatal vitamins and a healthy diet. And finally I go over a medical paper published in just the past month proving that those women who have contracted the Man Flu virus were not just viable donors but actually hyper virile during their week with the penile outgrowth symptomatic of this new flu strain. I explain how the only real difference in semen between natural males and females affected by the virus was that the sperm of the females were statistically superior in motility and lifespan and that they all carried X chromosomes exclusively, therefore pretty much guaranteeing and XX zygote and thus a daughter.

I then conclude the presentation by closing the binder and saying. “We were hoping for a girl anyway.”

Scarlett sits staring at the closed binder with confusion painted across her face. Thirty seconds, a minute goes by in total silence as she contemplates all that she had heard. On pins and needles I await her reply.

“So…” Her brows crinkle and her face twists. “…you wanna bang?”

“Bang?” I let out huff of frustration. “No! Weren’t you paying attention?”

“I mean, sorta.” She looks up at me. “What are trying to tell me, Fern? Plain English please.”

I sigh as I try to sum up all of my hard work in just a sentence or two. “I am saying that Stephen and I have been trying to have a baby for a long time now.”

“And Stevie’s shooting blanks. HA!”

“It’s not funny!”

“No. Of course not.” She wipes the smirk from her face. “Sorry.”

I try again. “I am saying that my fertility window just happened to line up perfectly with you contracting this flu. And since you are genetically the closest person to Stephen…well…”

“My baby would be as close thing to the real thing as you can get.”

“Exactly.” I say. “The child would still be of his bloodline. I know that is important to him. It is to me as well.”

“So you DO wanna bang!” She claps her hands. “God damn, Fern! You want me to help you cheat on my brother!?”

“NO!” I cry. “I mean…yes, but not really. But…but….” I slump down onto a chair, shoulders sagging. “We’ve been trying for three years, Scarlett. And it’s not getting easier. I’m going to be thirty next month…and…and…” Closing my eyes I struggle to contain the emotions that I promised myself that I’d keep covered up. “I don’t want to cheat on him but…we just want a baby. I want a baby. More than anything. I love your brother but…if he can’t….if he won’t…” I shudder and say again. “I just want a baby, Scarlett.”

“Heyyy.” Reaching across Scarlett grips my arm. “It’s okay, Fern. I get it. You’re feeling your biological clock. It’s normal. I’ve been feeling it myself since the big 3-0.”

I look across to her with pleading eyes. “So, you do understand?”

“Yeah.” She pats my arm and sits back again. “I do. It’s weird, don’t get me wrong, but I can see where you’re coming from.”

“Oh good.” I let out a breath of relief.

“And you said that all this was his idea?”

“It was just a throw away joke. Barely a quip.” I say. “When you told us that you got this flu Stephen jested that it was too bad that he couldn’t borrow yours for the week. It was enough to set this idea in motion. I never would have thought of it myself.”

“That’s kind of funny actually.”

“I don’t think so.” I say, my voice turning gravely serious. “Before you decide, you need to understand that this does come with some small risk to you.”

“Risk to me?”

“According to a few early studies there is some evidence that the more that you, erm, use what you’ve got…”

“The higher the likelihood that it becomes permanent.” She finishes my statement. “Yeah. I was reading about that. The chances are still extremely low…”

“But higher than if you remain chaste.” I say. “And you must be comfortable with not having a claim on the child. The baby will be Stephen and I’s, not yours. You will be the auntie, nothing more or less.”

“I get it.” She says. “No problem there. Hmmm.” She ponders a moment. “Cucking my own brother?”

“Scarlett!” I protest. “You would NOT be cucking him.”

“Sooo…you want to use a turkey baster or something?”

“What!? No!” I say with growing annoyance. “It must be, erm, straight from the source if we’re going maximize our chances.”

“So you DO want me to cuck him.” She grins. “Just say what you mean Fern and this will be a lot easier.” Before I could reply she holds up a hand. “I wasn’t saying that it was a bad thing. I actually owe that shit head a good cucking. I just…don’t want to mess things up between you two.”

“You won’t mess things up for us.” I insist. “And what do you mean that you owe him a good…what you said.”

“Well…” She runs her fingers along the edge of the binder. “…since you’re putting it all out there I might as well too. You’re tall, blond super stud Stephen used to go by Stephanie. And Stephanie was a fucking bitch.”

“What…are you talking about?”

“I’m talking about the eight months that I didn’t have a twin brother, but a twin sister. During our first year of university Stephan was still finding himself and he tried some things.” She says. “Ask him about his freshman year sometime and watch him blush. That’ll tell you all you need to know. He’s embarrassed about it now, though he really shouldn’t be. He rocked at being a chick.”

“Stephen was trans!?”

“Nah. Turned out he was just another straight dude in the end. Probably has a cross-dressing kink, but that’s none of my business.” Even as she said it the mystery of my stretched out panties was suddenly making more sense. Why hadn’t he told me? “But he explored being Stephanie for nearly a year.” She taps the binder. “Just long enough to steal someone who I thought was a pretty great boyfriend. I was wrong, but I thought it at the time. Cheating prick.”

My whole world was spinning. Stephen had been with men in the past!? This couldn’t be my macho boyfriend that she was talking about. “Steal? As in…?”

“As in sucked, fucked and cucked. Hey! Stephanie was gorgeous.” She chuckles. “She was hotter than me, easier than me, gave better head than me, I couldn’t even blame him for dumping me for the sluttier twin. It was definitely better in the long run. But it was just that they did it behind my back that got me. Bad enough for it to happen at all, but for it to be my own twin of all people? You know how competitive Stevie and I are at the best of times. I’ve long since forgiven him but…it’s always hung there between us.”

“Sluttier!?”

“Yep. That slut Stephanie cucked me good.” She grins. “And it appears as if the universe is balancing itself.”

“Scarlett.” I say, forcing myself to get back on track. There would be time to reflect on this huge revelation later. “If you’re thinking about doing this out of some sort of revenge…”

“Not revenge.” She raises a finger to correct me. “Simple payback. ”

“He can’t know about this.”

“But I’ll know.” Her smile grows. “And that’s enough for me. Listen, you get your baby. I even the score with Stevie. We both get what we want. What do you say?”

I think for a few seconds. I would have preferred her to do this altruistically but if she needed this to be transactional…so be it. As long as she kept the secret.

“Alright.” I say. “But, no more saying that you are cuckolding Stephen. This is strictly business between you and I.”

“Oh yeah?”

“Yes.” I say firmly. “We are not doing this for pleasure. I’m not going kiss you or orgasm for you or even look in your eyes. My eyes will be closed thinking about Stephen. You don’t need to bother getting competitive or anything. I belong to Stephen heart, body, and soul. You just…do your thing as efficiently as you can and I’ll do mine. Then we pretend it never happened.”

“How romantic!” She fans herself. “Why Fern, I think I’m falling in love.”

“Exactly. It’s not romantic.” I say. “I like you, Scarlett, just not in that way.”

“Fair enough.” She wipes her hands on her shorts. “Before we shake on it there’s something you really ought to know.” Her right hand strays to her crotch where she grips it quite crassly. “This funny old virus has blessed yours truly with an above average symptom.”

“Hmph. You’re brother is above average as well. I am sure I can handle you.”

“There’s above average and the there’s…”

“It doesn’t matter.” I cut her off. “Even if you are a tiny bit bigger, size doesn’t matter. Everyone knows that’s a myth.”

“Uh huh.” She says. “How many guys you been with, Fern?”

“My share.” I say defensively, not elaborating that ‘my share’ was precisely two. “So do we have an agreement?”

With a funny smirk on her face she slowly nods and extends her hand. “I’ll put a baby in ya, sure enough. And on my life I won’t breath a word of this to anyone.”

“Thank you.” We shake hands to seal the deal. With a glance to the clock on the wall I get to my feet. “Time is ticking. We should get started. Virility peaks in the morning hours. I hope you haven’t masturbated yet today.”

“Wait, now!? Here!?” She laughs again and slaps her knee. “Geeez!”

“Right now.” I state the obvious. Hadn’t she heard a single word of my presentation?

“God damn you work fast, girl.”

“I only took the mornings off this week. It was the best I could do without tapping into vacation time.”

“The mornings?” Scarlett says. “Plural? So this isn’t a one time thing?”

“Of course not. Getting pregnant is like rolling dice.” I explain. “The more you roll the higher the chances you get the number you’re after. I’m hoping to at least do this once a morning, plus any other times we might be able to schedule. Stephen will be having me every night to keep up on our schedule too. Who knows, it might even be his in the end.”

“That’s a lot of sex in a week.”

“A necessary ordeal. I’ll do anything for this baby.”

“Well don’t consider it an ordeal, Fern. Think of it as a bounty! A bounty of nookie. Ha! Every morning. You and I are about to get reeeeal friendly this week.” She holds her hand up before I could complain. “I know, I know. Strictly business.”

“Right!” I nod confidently…then wilt completely. The build up I’d been prepared for, not that the moment was actually here? Eeep! “Er…so…h-how do you think we should…erm…”

“Relax, Fern.” Scarlett rises to feet and comes to stand close to me. Gosh she was tall! Gazing down into my eyes she gives me a warm smile.

Mesmerized by those familiar yet subtly different hazel eyes I whisper. “W-We sh-should do it m-missionary or doggy for maximum…um…”

“Why don’t you let me take care of things from here?” She runs a hand down my arm, sending a shiver back up my spin. “You just think fertile thoughts, hmm?”

“Okay.”

“First of all.” She pulls the mask’s elastic from off of my left ear. “Let’s see that pretty face.”

Pretty? This gorgeous bombshell thought I was pretty? Was she teasing me? The intense way she was looking at me sure didn’t seem like she was teasing.

“W-Wait.” I say, too late, as the mask is pulled away. “The virus.”

“Symptoms don’t show for 6 or 7 days.” She says. “And while the vagina is affected the womb is left untouched.”

“6 or 7 days?”

“It’s simple science.” She tosses the mask to the table. “Do your research if you don’t believe me.”

“I…believe you.”

One by one she begins to pull the pins from my hair to let it hang freely. These too she places on the table behind her then teases my auburn locks so that they lay more naturally. “Let’s retire to somewhere more comfortable.”

“Okay.”

She slips her lean arm around me and holds me close to her side as she leads me through her house toward her bedroom. “Ever been with a chick before?”

“No.”

“Me neither. Never had a dick before either.” She gives me a supportive squeeze. “We’ll figure it out. It’s just biology after all.”

“Um…yeah.” Pressed against her firm, sweaty body my nostrils are filled with her natural aroma. Her body felt nice. Her aroma smelled nice. She was nice. I blink my eyes hard and remind myself that none of this stuff mattered. I was here to do a job.

Scarlett brings me into her bedroom which I discover to be surprisingly nice. Though there was as undeniable feminine touch about it, with all of her trophies and inspirational posters on display in the other rooms you could tell that this was the home of an athlete. But in here she had this really classy jade and off white decor that I found myself jealous of. There was lovely floral art on the walls, pillows aplenty on the big bed, and just every little thing screamed out that this was a style that had not been touched by the sensibilities of the other sex. It also smelled…green. I didn’t recognize the gentle scent but it was wonderful.

“Okay, cutie.” She swats my bum! “Let’s get you naked.”

“Excuse me!” I giggle, despite myself, as I rub my tush. “We don’t need to get naked for this. I will take my panties off and pull up my skirt. That’s enough.”

“Work with me here, Fern.” She says, her as voice smooth as honey. “You’re real pretty but I’m as straight as you are.” Grabbing her crotch again she gives it a grope. “And this thing doesn’t exactly perform on command.”

“Oh.”

“This is going to be more difficult than it needs to be if you keep fighting me.”

“Sorry.” I say. “I never thought about…that.”

“You said you’d let me take of things.” She caresses a hand down my back which sends tingles through my body. “Let me get comfortable. Let me do my thing. I’ll look after you, Fern.”

“Okay.” I cede to her control.

Stepping up she looks me up and down. If she was thinking unflattering things about my buxom physique I couldn’t see a hint of it in her gentle grin. She touches my shoulder then slides her hand down my chest, feeling for the first time what it was like to touch a woman in this way. She unfastens the top button of my cardigan, then the next, and then the next. Smooth, deliberate, unhurried she undoes them all then slips it off from my shoulders. She gives it a fold then places it on small table she kept beside her dresser.

“Cashmere.” She pets the pale yellow garment. “Very nice.”

I swallow hard. “Thank you.”

Taking my pudgy hands into her slender, elegant hands she rubs her long thumbs across the back of my fingers. “If you don’t mind me asking, why hasn’t my brother put a ring on this finger yet?”

“Oh, um, he thinks marriage is a…pointless and antiquated tradition.” I say as stare down at her lightly massaging my fingers. “It’s not necessary anymore.”

“Hmm. Might not be necessary.” She says softly. “Still a nice thing to do though.”

She brings my left hand to her lips and kisses it. Her lips were so tender. I clear my throat and swallow. “No…kissing please.”

“Sorry.” She smiles.

Letting go of my hands Scarlett proceeds to unbutton my shirt. I felt mighty self conscious at my squishy body being revealed in front of this paragon of the peak female form but, thankfully, her warm expression never once betrays that she was thinking anything but kind thoughts. She pulls my shirt from my skirt then slips it off as well and carefully piles it on top of my sweater. A shiver runs through me when the next time she touches me it was on bare flesh.

“So soft.” She whispers as she runs her sun-kissed fingers across my plump, pale tummy. “You are so beautiful, Fern. Stevie is a fortunate man.”

“Oh!” I gasp at the unexpected compliment. I don’t know why but coming from her…it hit differently. “I-I’m not pretty. Not like you. I-I…”

“Shhhh.” She places finger over my lips. “Relax.”

I look into her eyes and nod.

“Good girl.”

Stepping in close to me, so close that I can feel heat from her body, she reaches around and unfastens my bra. As the steps back again she pulls it with her to free my large breasts. Unlike hers mine were not firm and perky. Mine were full and heavy and sagged partly down my chest, the big round tawny nipples pointed straight ahead.

“Damn. You’ve got a great rack, Fern.” I gasp as she gives one of them a gentle squeeze. “I’m jealous.”

SHE was jealous of ME? How was that even possible? What with those strong thighs, that tight behind, those exquisite curves, those perfect abs, those breasts that defied gravity, those wonderful muscles of her shoulders and arms, and that long elegant neck… “Hmm!” I shake my head and stare off toward the wall behind her.

As I try to refocus on the task at hand Scarlett was already pulling the zipper on my skirt then allowing it to drop and pool around my feet. Kneeling she has me step out of it to pull it away and add it to the pile. My socks soon follow. My body was lighting up like a Christmas tree as I stand there in just my panties. I felt tingles all over and a rush of nice feelings to my breasts and pussy. If I didn’t know better I would have thought that I was becoming aroused.

Standing back from me Scarlett holds out her hand and commands me. “Panties.”

“Oh, um, yes. Of course.” Not nearly so suave as her I yank my underwear down around my ankles then step out of them. Just as I am handing them off I feel the warm, moistness of the crotch! The way her one eyebrow raised I could see that she felt it as well. I blush furiously. “I-I’m in my fertile window and easily…”

“Easy, Fern.” She soothes me with her silky tone. “It’s cool, baby.”

“D-Don’t…call me baby.” I try to swallow. Though my panties were wet my mouth was bone dry.

“Nice trim.” She nods toward my neatly trimmed pubic hair.

My blush burns hotter. “Uh…yeah…Stephen l-likes it this way.”

“Missionary or Doggy you say?” She asks as she lays my plain white panties across her dresser.

“Ahem, yes.” I say. “Missionary preferably. It allows maximum penetration.”

“Heh! I don’t think that’s going to be a problem.”

Taking me in her arms like a dancer she guides me toward her bed and sits me down. I go to lay back but she holds me in a seated position to indicate that is where she wanted before letting me go.

Pinching my bottom lips she says. “I’m going to need a little help before we get to business.”

“Help?” I say. “You mean oral sex!”

Hands on hips she lets out a loud laugh, those abs of hers showing through on each chortle. “Yes, Fern. I mean oral sex. You do do that, don’t you?”

“Well…yes. I just…” I sigh, remembering that it was her doing me the favor here. “Very well. I’ll do my best.”

“Good girl.” She winks.

Good girl? That was the second time she’d said that to me. Even Stephen didn’t call me that. Who did she think she was? I let it lay though. There was no point rocking the boat. Besides, it wasn’t really that bad. It was somehow flattering coming from her.

Without a shred of bashfulness she pulls off her sports bra, balls it up, and throws it with impressive force and accuracy into the laundry basket in the corner of the room. Dang! Her boobs were even better than they looked under the spandex. Not squashed down her full round shape was able to express itself, her small pink nipples pert and pointing slightly upward. Unlike mine they didn’t sag a bit. Seeing me looking at her she pauses and gives me a flex and a pose. What a body!

I blush and turn my head. “That’s not necessary, Scarlett.”

“Yeah, but you’re cute when you blush.”

She then pulls down the baggy sweat shorts and tosses it over her shoulder, nothing but basket. Suddenly she goes still, simply standing there with her hands on her hips. Curious what the hold up was I look back to her…and see that those shorts had been hiding. There running down her right inner thigh was a prodigious tubular shape. Bending the tight fabric at her crotch was a huge round bulge. I knew the one was a penis and the other her balls, but…but…BUT…

“What is that!?” I point at the humongous cock outlined by the fabric of her blue leggings.

“That, my dear, is what I was trying to warn you about.” She says, a bit too proudly.

“You’re hard already?”

“Oh, it’s not hard.” She pokes at the shaft to prove it still had some sponginess to it. “It’s got someway to go yet.”

“But…but…how’s it so BIG!?”

“Just my luck.” She chuckles. “I got the Alpha strain.”

“Alpha strain? Th-That’s just an…urban myth.”

“Fact or fiction, all I know is what I got here in the flesh.”

With me gawking at her junk she pulls down the leggings to let the beast spill free. Thick, long and veiny it sways back and forth like a big, meaty pendulum. Not even hard yet Scarlett’s penis completely dwarfed her twin brother. Her snug scrotum hugging her big testes were similarly proportioned, roughly twice the size of Stephen’s. Also unlike her brother’s her pubes had been shaved away entirely to make everything sleek and smooth.

“I tried to warn ya.” She says as she takes a grip of her thick shaft. “If you’re having second thoughts…”

“No!” I blurt out, quicker than I meant to. “No, it’s just…surprising. That’s all.”

“You’re wondering what it feels like, aren’t ya?”

“What?” I say, flustered. “No, of course not!”

“Well I’m wondering! Ha! Damn shame I couldn’t fuck myself with it.” She waves it back and forth. “Biggest guy I ever had was maybe seven and half. You?”

“Ahhh, Stephen’s the biggest…I’ve…HAH!” I gasp and point as the ruddy knob swells causing the foreskin to roll back a quarter inch. “It’s growing!”

“I think that’s what they’re supposed to do.” Her eyes twinkle with amusement. “You think I’ll get deep enough for you?”

“Uhhhh.” I was speechless. Never had I imagined that I’d ever be facing anything like…THAT! It was just so big. My pussy twitches as I stare at slumping nine inches of flesh. It wasn’t fully flaccid by any means but it was clearly not hard yet either. “How…big…”

“Does it get?” She finishes my question. “Exactly eleven inches. Smidge over seven and a half around.”

“Eleven! Seven and a half…inches around!?” In handling it I’d estimated Stephen’s manhood to be somewhere between six and seven inches and it was definitely less than six in circumference. With rough facts and figures to grasp onto my math brain kicks in, that would be…a hundred and seventy percent my boyfriend’s length, a hundred and forty percent his thickness, and a whopping three hundred percent or more by volume! Scarlett was THREE TIMES the size of her brother!? “What?”

“Yeah. It gets crazy big. I measured it last night when I was rubbing out my first load. That shit was INTENSE I can tell you.” She clubs the fat tip against the palm of her other hand. “I can see why guys are always thinking with these things now.” Letting it go again she lets it swing as she pulls her workout leggings off of her toned, muscular legs. “I came so much. More than any guy I’ve been with. I’d never seen so much spunk. But it was my first time I suppose. If nothing else I think my little spermies will get the job done through sheer overwhelming numbers. Ha ha ha!”

“Eleven inches!” I mutter then after a second shake my head. “It doesn’t matter. All that matters is the baby.”

“That’s good.” She quips. “Because after this big cunt stretcher you won’t even feel little Stevie anymore.”

“Scarlett!”

“I’m joking!” She laughs. “You and I both know that’s not how vaginas work. Geez.”

I let out a loud huff, a bit miffed at her joke at Stephen and I’s expense. “Whatever. Just…go easy on me and…use lube if you’ve got it.”

“I got it.” She jogs to her bed stand, tits jiggling, balls bouncing and big white cock swinging. “Here we go.” A tube of clear lubricant is produced and strolls back to the foot of the bed. “This stuff’s really nice.”

“Sure.” I say. “Can we just get this over with please.”

“Hey.” Scarlett says as she tosses the bottle onto the bed beside me. “Relax, baby.” She strokes my hair. “You’re so tense. You always this tense?” Bending down she looks into my eyes and gives me one of those lovely smiles. “Take a deep breath, Fern. Relax.”

I pull in a long, slow, deep breath then let it out just as slowly.

“Good girl.” She pats my cheek. With the same hand she then pinches the bridge of my glasses and pulls them from my face. The world suddenly goes fuzzy. I watch the blurry behind of Scarlett recede as she places my glasses on her dresser. “I’m not sure if you’re cuter with or without your glasses.” Turning around she approaches me. With me sitting and her on her feet her big dick comes into sharp focus while the rest of the room remains blurred. Damn it was BIG! Her hand softly pets down the back of my head. “If you could fluff me up we can get started.”

Another deep breath and I nod. There was nothing for it, I needed her to get erect so this was a necessary step.

Reaching out I lightly take Scarlett’s organ in my hands and lift it toward my mouth. The size was unlike anything I’d felt before and the hefty weight of the flesh was not entirely unpleasant to feel. It was SO different from Stephen’s. I pull back the foreskin to fully reveal the darker head. Summoning my determination and with my purpose foremost on my mind I close my eyes, open my mouth, then wrap my lips around the head of Scarlett’s big cock. Though she wasn’t hard I had to open up as wide as I could go to fit her girth through my lips, and once through the meat filled my open maw to the brim.

“Hm!” I peep as I feel the knob and shaft swell inside my mouth.

“Oh, damn that’s nice Fern.” Scarlett takes a handful of my hair and grips it tightly. So dominant! I wished Stephen would grab my hair like that. “That’s it, baby. Suck that big dick.”

“Mmmm.” I pull back, giving her a long, firm suck as I go.

“Fuuuck.” She moans to my oral. It was so strange to hear a soft woman’s moan instead of Stephen’s deep groan.

“Mmm.” I push forward to take in as much of her as I could. If I held my boyfriend in both hands as I was doing to her right now there’d be almost nothing left peeking out, but with Scarlett I had plenty of room to suck even with the two handed grip. When I had all I could inside of me I pause to suckle in the way that her brother enjoyed so much. Sister enjoyed it too.

“Ohhhh, Fern!” Her other hand joins the first, grabbing my hair from the other side. As she does so my wet pussy twitches again. “That’s it, girl. Suck that fuckin cock.”

Taking control she pushes my head back then pulls it into her again. Ohhhh, I liked that! Surrendering to her I let her push and pull as I suck the growing penis sliding through my lips. “Mmm, mmm, mmm!” As I gave her head I very quickly came to enjoy the feeling of such a large dick. I enjoyed it’s weight, it’s powerful size, and the way it forced me to work hard at giving it pleasure. “Mmm!”

“Play with your pussy.” She tells me, and I do. Freeing my right hand from her hardening shaft I start to play with my yearning clit and slit…until I remember that I wasn’t here to enjoy this. Just as quickly my hand returns to her penis. “He he he.”

Opening my eyes I glare up at her, though the glare quickly turns to a gaze as I behold her fit goddess body looming over me larger than life. Her taut muscles, her tight abs, her beautiful perky breasts, her gorgeous face, and the way those intense hazel eyes looked down on me like they owned me…it was all so overwhelming. This woman was superior to me in every way but instead of the usual jealousy I would feel normally, this time I liked it! It felt so right for her to be over me, controlling me, dominating me sexually…

“HRM!” I grunt and blink my eyes. Snap out of it, Fern! Slipping off of her schlong I smack my lips and whisper. “Too big.” I stretch out my jaw as I focus on stroking her with both hands. She was sooooo long! The strokes seemed to go on forever. And her girth was such that my pudgy little hands couldn’t even come close reaching all the way around. THIS monster was going to be inside of my vagina!? “You’re too big.”

“Do you want to stop?”

“No.”

“Didn’t think so.” She grins. “It’s pretty cool, huh?”

I grumble then say. “It’s too big.”

The truth was though, it was pretty cool. Feeling such a huge specimen grow in my hands excited me in ways it really should not have. By its sheer size it exuded this commanding energy that an average sized one simply couldn’t. It made me feel small and meek and gratefully feminine in strange sort of way. To increase her pleasure I kiss and lick at her knob while my left hand strokes and my right fondles her bulky balls. Such big, plump testes. Each loaded with millions of strong, healthy sperm. As I sucked and fondled my mind began to imagine what this big cock was going to feel like inside of me. It was intimidating, terrifying, yet my curiosity was far more than my fear. Besides, if I was going to have a baby the old fashioned way, as I wanted to, I was going to have to pass something much larger than a mere penis through my vagina. The little puddle dampening Scarlett’s bedding was embarrassing, but I blame it on how easily I became horny during my fertility window.

“Good girl.” Scarlett croons as she teases my hair. “I think I’m about there, baby.”

“Okay.” I whisper breathlessly as I gawk at the fully hard eleven inch erection hovering before me. “Ohhh!”

“You’re looking a little flushed there, Fern.” She teases. “You sure you’re not enjoying this?”

“No!” I snap as my mind returns to where I was and what I was doing. In the most mechanical and straightforward manner I lay back on the bed and spread my legs. “Hurry up and do it.”

She chuckles at my annoyance. I was grateful however when she did not hurry up, instead choosing to take the time to apply some lubricant to the already wet end of her massive member. Squirting a bit onto her fingers she then makes me flinch as he rubs a good amount against my pussy.

“Hmmm!” I try to hold in a whimper as her fingers rubbed so nicely against my sex.

“So hot and wet.” She says in a sultry voice. “Fuck baby, you are fertile today.”

“HAH!” I yelp as she slips two long fingers into my pussy. “What…are you doing?”

“Just warming you up.”

“I’m already warmed up.” I say through quickening breaths. “Please hurry.”

“So impatient.” She laughs and gives my wet cunny a little slap.

“Eep!”

Mercifully she pulls her hand away from my glowing pussy. I had decided from the very beginning of this process that the one thing I would not do this week is orgasm for Scarlett. It might be a silly thing and even went contrary to the best practices according to some the fertility research I’d done but felt that as long I didn’t cum for anybody but Stephen I was, in my own way, staying true to him. I hadn’t even worried about it as with Stephen I always needed to be in the right frame of mind to climax. If I wasn’t fully in the mood orgasms simply didn’t happen. But I was worried now. Something about Scarlett and her oversized phallus had me feeling things I hadn’t expected to feel. And when she was rubbing my cooch just now, well, it felt reeeeally good.

Legs spread, arms at my sides, I stare up at the ceiling and narrow my focus back to the task at hand. There was nothing sexy about this. I didn’t love this woman. We were here to get a job done and nothing more. It didn’t matter that she was gorgeous and that she had massive, hard, throbbing cock.

“Hahhhh!” A gasp escapes me as I feel something big and warm and slick press against my over excited pussy.

“You should see this.” Scarlett says as she rubs her tip up and down and up and down. “I’ve never seen such a wet cunny before.”

“Hmmm!” I mewl as I push back against the sensations that her penis was arousing in me. As I fought it though my pussy begged for it. It wanted, needed, to feel something inside of it soon. Staring resolutely at the ceiling I say defiantly. “You gonna use that thing or just play around all morning?”

“Mreow! Down girl.” She says. “Get ready, here it comes.”

I grit my teeth and grip the covers as I feel the pressure against my entrance gradually increase. As big as she felt in my mouth and my hands she felt double that pressing against my slit, something else entirely from the more focused and easier penetration of her brother. Had I not been worked up, had I not been in my easily excitable fertility window, and had both her and I not been so properly lubed her progress would have been halted. As it was though, my vagina parts for her like a crashing wave split by the prow of a mighty ship. Her tapered tip pointing the way she slowly, steadily enters me. As she does she gets thicker and thicker and THICKER!

“OOOOHHHH!” I hear my cry as my cunny is opened like never before! “W-W-Wait!” I grab her arm. “Wait! Hmmmm!”

She stops, just a few inches in, to let me struggle against her girth. “Told you it was thick.”

“Ohhh…haaahhh…hohhhhh.” I take long deep breaths as I fight to adapt.

“That’s it, baby. Breathe. Relax.” She caresses my breast. “You’ve nearly got the thickest part already.”

“Mmmm.” I nod, grateful for the news. If she was any thicker I swear she’d break me in two.

“You okay?”

“Mmm.” I nod again and close my eyes. “Just…hmmmm…it’s a lot. Go slow.”

“You got it.” With that she pushes the next two more inches inside of me, which just happened to be the thickest two.

“HAAHHHH!”

“Holy shit!” She exclaims as she marvels down at my cooch. “You’re so fuckin stretched!”

“HMMMM!” My chubby body trembles, every muscle tight as I stare up at in red-faced anguish. “BIG!”

She smiles and caresses my hot cheek. “Breathe. Breathe. Relax. You’ve taken the worst of it.”

“Hmmmmm.”

“Good girl. Such a good girl.” She pets me and soothes me. “You’re doing so good, Fern.”

Her gentle encouragement helped considerably as over the next few minutes I was able to calm my emotions. As my mind, so to followed my body. The more I was able to relax the more I found my tunnel was able to adapt to the intense stretch that her thick, hard cock was causing me.

“Hahhh.” I exhale and close my eyes. “Okay. I’m okay now.”

“Atta girl.”

“Eeemm.” I whimper as she pushes another inch or two in, as deep as Stephen ever go, then slowly back again until she was nearly out…then in again. “Ohhhhhh!”

Her hand softly kneading my big breast she gingerly works six inches of her penis in and out in smooth, steady thrusts. “What’s it like?” She whispers.

“Full.” I huff. “I feel…full.” Full didn’t even come close to describing the sensation. Stuffed, crammed, or bursting might have been better descriptors. “What’s…it like…for you?”

“Oh, Fern.” She sighs. “It is wonderful! Oh my God, I’ve never felt anything like it before. You’re so tight and warm and…nnngh….oh my God. Way better than my hands.”

“Good.” I swallow hard. “Shouldn’t take you…too long then. Hmmmm.”

“How long does Stephen usually last?”

“None of your business!”

“Ha! I’ll do my best.” She says with a hard squeeze of my tit.

With her as hard as she could be and me as ready as possible the real sex then begins.

Gradually her slow, careful thrusts increase in speed and power, each one getting easier and filling my pussy beyond what I ever dreamed was possible. Right away an irresistible energy begins to build as the sensation of her shaft gliding through my stretched canal sent waves of pleasure coursing from my groin and out through my body. Everything was so taut and full I had no way of retreating from it. No matter how I relaxed or gripped or shifted Scarlett’s cock FILLED me in the most spectacular way.

Oh no! It felt good. It felt good! It felt so fucking GOOD! IT FELT BETTER THAN STEPHEN!

“Hmm. You…almost…done?” I somehow manage to mewl.

“Hm? Nah.” She answers. “Feels fantastic, but I’m just gettin warmed up.”

“Well…cum already!”

“I’m trying.” She laughs. “This pressure to perform ain’t helping ya know.”

“Sorry.”

In, out, in, out her big, satisfying cock plunges. The longer she went the better it was feeling. Focusing on the ceiling I try to think the most pussy drying thoughts that I could but it was hopeless as with each thrust Scarlett pushed everything out of my mind except for how incredibly good this was feeling. Ohhhh fuck. This stretch, this fullness, I never knew it could be this good!

And then it got better.

“OHHHHH!” A loud cry escapes me as on one thrust Scarlett pushes into parts untouched. “OHHHH FUCK! You’re deeeeep!”

“Eight inches, baby.” She says proudly. With her thumb she playing with my clit, something brother rarely did and never as good. She knew what a clit was and how to handle one. I might have protested but holding back my orgasm was taking all I had. “Let’s try for nine.”

“OHHHHHH FUUUCK!” I wail as the blissful fullness is taken up to another level. She said it was nine inches but to me it felt like she was up to my throat with everything blow it stuffed with thick cock. “HMMMMM!”

“Uh ohhh.” Scarlett sings. “I think someone’s enjoying themselves.”

“Mmm!” I shake my head in crumbling defiance. Her thrusts get faster and deeper. “Ohhhh God!”

“You sure?” Her lithe body flexes and bends as she thrusts. It had a sheen of sweat but no more than it had when I arrived, and she wasn’t the slightest bit out of breath yet. “You’re gonna cum for me, aren’t ya baby?”

“Mmmmmmm!” I shake my head again.

“You’re about to cum for this big cock, ain’t ya baby?”

“Nooooo!”

“You love this fat, long cock stuffing your cunt, don’t ya sweetie?”

“MMMM!”

“He he he. Keep fightin it, girl.” She pinches my nipple. “It’ll just make it all the better when it happens.”

Her piercing hazel eyes, so similar to my boyfriends, stare down at me as her thrusts quicken again. Loooong, pussy stretching thrusts that had me quivering and helpless. She was watching, waiting, for the moment of my release. Her moment of victory over her brother. And try as I might I could not stop it. If anything her smug look only made it harder. I think of Stephen, I think of the baby, I think of anything I could, but that deep driving cock was simply too powerful.

“Hrm! Hrm! Hrm! Hrm!” She grunts as she fucks me hard, fast and deep, that incredible thumb of hers never giving my clitty a moment’s rest. “That’s it, Fern.”

“Noooo.” I mewl pitifully even as my body surrenders.

“He he he. Come on, baby.” She pulls her elastic out and tosses it to let her long, blond hair swing free as she fucks me so deep and good. “Cum for Scarlett.”

“Hoohhhh! Ohhhhh! Ahhhhhh!” My lilting voice rises with the ecstasy radiating from my pussy. It was too much. She was just too much. I…couldn’t…stop…it. Whoosh! “OHHHHHHHH!!!”

“There she goes! Ha ha!”

“OHHHHHH!!!” I howl as a body-wracking climax that had me doubting every one before it savages my shuddering flesh. As I writhe beneath her the grinning Scarlett never lets up. “OHHHHH GOD!!!”

I was lost in my sexual bliss. In holding back it just ends up hitting me twice as hard. Rushing wave after wave of pleasure course through me. I’d fought my orgasm every step of the way but Scarlet had just made me cum faster, harder, longer, and just plain better than her brother ever had. And that was just the first one. With my hung blond goddess not giving me a moment’s respite I end up cumming again hard on the heels of the first. It was incredible!

When at last I come out of my haze I discover Scarlett standing over me, hands on her hips and dick still buried inside of me, with a huge, proud smile on her face.

“That wasn’t so bad, was it?” She quips.

“Ohhhhhhhh.” I moan as the aftershocks of the unbridled ecstasy continues to ripple through me. “Ohhhh, Scarlett.”

“Ha!” She slaps one of my tingling titties, and I love it. “You know, for a little lady you can take a big fuckin dick.”

“Nine…inches…whooooooo.” Sweaty and gasping for air all I can do is writhe.

“Nine?” She chuckles. “You took the whole fuckin thing.”

“Huh?” I look down to see that she all the way inside of me! Not one sliver of her eleven bulky inches could be seen! “Oh wow!”

“Wow indeed.” She pinches and paws at my breast. “That was a hell of an orgasm.”

“Ohhhhhhhh.”

“Bet Stevie never made ya cum like that before.”

I consider lying, but what was the point? There was no comparison. After that, I wasn’t even sure I’d had a real orgasm before today. Fucked into submission I give her the honest answer that she wanted. “No.”

“Yesss.” She actually does a fist pump just like she did when she’d win at one of her events. “Scarlett wins again Stevie.”

“Okay.” I gasp. “Whoooo. Okay…well that was…something new. Thank you for…”

“Was?” She cocks her head. “Fern, I haven’t cum yet.”

“You haven’t!?”

“No!” She throws her head back and laughs. “It’s barely been five minutes!”

“That’s… it!?”

“That’s it.” Grabbing my legs behind the knees she pushes them down to spread them wide and pin me to her bed. “And now that I know you can handle me, I’m gonna stop holding back.”

“Holding…back!?”

“If I’m gonna cum I need to go all out.” She says, leaning her weight into me and grinding her massive schlong as deep as it could go. “You want this baby, don’t you?”

“Yeah!” I peep.

“Atta girl.”

Hovering over me, eyes drilling straight down into mine, my future sister-in-law fucks me with passion and fury. Eleven gleaming inches of thick female cock slam in and out my sopping wet pussy again and again and again.

Plap! Plap! Plap! Plap!

“Ohhhhh!” I cum again for her in no time at all, my pussy gripping against her thrusting shaft in a vain attempt to milk the sperm from her. But I was learning that Scarlett didn’t just have size, she had stamina for days! Again and again and again she brings the woman out of me like only a woman like her could. “OHHHHH!!!”

Plap! Plap! Plap! Plap!

Her strong, hard body tirelessly pounds down into my soft jiggling one and on each hammer blow the thrilling, filling pleasure of those eleven toe curling inches hits me again and again and again.

“OHHHHH!!!”

Plap! Plap! Plap! Plap!

“Grm! Ngh! Mmm!” Her soft grunts accompany each impact. Her firm breasts jiggle as mine bounce. Her abs are stone as my jelly belly wobbles. Hair hanging around her face and swaying to her motion that hazel gaze of hers continues to drill into me. Not simply satisfied dominating me, she was out to conquer. And conquer she does! Again and again and again!

“OHHHHHHHHH!!!”

Plap! Plap! Plap! Plap!

Lost in my complete sexual surrender I can simply lay and howl my ecstasy as my boyfriend’s sister fucks me better than any man ever would or could. How long she fucked me? I hadn’t a clue as time had no meaning when you were bucking from one powerful, mind-blanking orgasm to the next. How many climaxes I had? There was no way to count as one had barely quelled before the next claimed me again. And all the while that relentless athlete’s endurance held strong.

Plap! Plap! Plap! Plap!

I was flagging hard, my body limp and my mind broken past the point of simple orgasm into a steady exhausted euphoria. My body hers until she was done with it I gaze up at my goddess and receive her bountiful blessing. “Hohhhhh…”

Plap! Plap! Plap! Plap!

And then, at last, the moment finally comes. Fucking me harder, faster and deeper than ever, her hard hissing breaths coming through clenched white teeth and sweat dripping from her nose and chin, Scarlett hammers down into a powerful mating press and holds firm.

“GNNNNNGHHHHH!!!” Every muscle in her perfect body flexes as her face trembles while deep, deep inside of me I feel…throb, throb, throb…as she floods my fertile womb with her hyper-virile seed.

I didn’t think I had it in me, but feeling her rush cum fill my insides sends me over for one last trembling climax. “Ohhhhhhh!” It was a waking dream, I know, yet I would go to my grave swearing that I could feel her sperm fertilize my waiting egg. “OHHHHHH!!!”

When it was done Scarlett collapses on top of me, sweaty and out of breath like she’d just had one hell of a work out. Which I suppose she had.

“Ohhhhh.” I coo weakly, my mind and body spent in ways I’d never felt. My pussy was nearly numb from the overload of pleasure. I wrap my shaking arms around my lover’s body. “Ohhhhhhh Scarrrrlett!”

She kisses me on the cheek. “Not bad for my first time, huh?”

“Yeah.” I giggle. “Not so bad.”

When she pulls out of me to lay at my side it leaves me hollow and literally gaping. Thank goodness I didn’t have to make love to Stephen now. I wouldn’t have even felt him. I pull my legs into my body and hold them there, doing my best to tighten my snatch to hold in all that precious semen. Not that I was worried anymore. Somehow, I just knew the job had been done.

Scarlett holds me close as I float in the afterglow to end all afterglows. I’d be feeling it for a week!

“Ohhhh, thank youuuu.”

“Poor little Stevie.” She chuckles as she swipes away the hair stuck to my sweaty face. “That’s gonna be a hard act to follow.”

What could I even say to that? She wasn’t wrong. My body might recover but I would never forget what sex could be. “Ohhhhhhh.”

After a few lovely minutes in Scarlett’s arms she gives me another hard kiss to my cheek. “Okay, I think I’m ready to go again.”

“Again!?” I whine.

“As often as we can.” She grins. “That’s what you said.”

“Ohhhh no!” I moan as she fills a hand with my breast and gives it a squeeze. “Ohhhhh yessss!”

***

For the next five days I receive the best sex of my life from Scarlett in the mornings and the best Stephen could give me at nights. Sore as I was I’d never been so happy for Stephen’s mediocre staying power. Tired but happy I endured it.

I contracted the flu in six days time, as I knew I would. Unfortunately for me I wasn’t nearly so resilient to the other symptoms as the fit Scarlett had been and spent most of that week sick in bed with sex the furthest thing from my mind. After the week before I needed the rest anyway. After I’d recovered and my body returned to normal a positive pregnancy test soon followed. The plan had worked. The gamble had paid off.

There was one price to pay to pay however. Sex was never the same with Stephen after that. He still felt good of course but that week with Scarlett made me realize that I liked them long and thick. I knew what sex could be now and through no fault of his own Stephen could never give me what I really needed. But I loved the man dearly and I gave him all I had I had to give, never leaving him wanting in the intimacy department. And I wasn’t left wanting either as my trusty and carefully hidden ten inch dildo, a gift from my new best friend Scarlett, never gathered dust for long. Our love life had changed but for a baby I felt it was price worth paying.

***

Nine months later Stephen and I were blessed with a perfect baby boy, seven pounds and five ounces with hair as blond as his dad’s. A boy! I couldn’t believe it. I just couldn’t believe it. It was a miracle! After all those incredible mornings with Scarlett it was Stephen’s little swimmers who had come through in the end. Happy days!

Or so we thought…until the nurse cleaned him off to discover a labia and clitoris just below the scrotum. Some very confused doctors soon returned with the baby’s first blood test that showed the child had XX chromosomes despite the presence of a healthy set of penis and testes. After some testing they said that while there was a penis the baby would grow up as a genetic female as its excess testosterone strangely seemed concentrated in the groin region. The warned us that she might grow up BIG down below but would otherwise appear as a normal female. Our son was a daughter! A daughter with both vagina and penis! They told us it appeared that elements of the Alpha strain of the Man Flu virus had somehow mingled with her DNA in utero causing this unique physical expression.

The first full futanari had been born.

The End
