Sex is the Best Way to Learn About Other Cultures. - Chapter 4.5

It was a year after I got married that I found out I couldn’t conceive a child with Takkun.

Takkun, who is ten years older than me, had a daughter named Saya-chan. Our marriage made me a second wife, but that never bothered me.

Saya-chan was cute, and she was fond of me, even though I was a “stray woman.” Our married life and new family were going smoothly, and I hoped that Takkun and I would have a child. I lived my life with that future in mind.

But no matter how long we waited, Takkun and I couldn’t have a child.

With Saya-chan already in the picture, I couldn’t imagine that there was a problem with Takkun. Thinking this, I went to the infertility clinic by myself,

 

“I see…”

 

I was informed of the cruel truth that it would be difficult for me to conceive with my body.

I don’t believe bl00d ties are essential for parent-child relationships. After all, Saya-chan and I make a perfectly fine mother and daughter.

Still, as a woman, the shock of being unable to bear children with the man I love was profound.

Adoption was an option.

But somewhere in my heart, I think I longed for the idea of ​​a new life that I could carry in my womb and be gifted through the painful experience of childbirth.

I really wanted a child with Takkun.

There was the option of taking a gamble on infertility treatment with its not particularly high success rate, but that felt like telling Saya-chan right in front of me, “I really want a child connected to me by bl00d,” which I couldn’t bring myself to do.

For the same reason, I couldn’t bring myself to tell Takkun about my infertility either.

Still grappling with these conflicted emotions, unable to abandon the idea of having my own child, I desperately searched for ways to conceive. That’s when I found it.

 

[Introducing a Japanese man who can reliably get any woman pregnant. The treatment fee is only 100,000 yen per session.]

 

“What is this?”

 

It was a customer recruitment post on a social media platform.

Impregnate any woman? The claim only raised my suspicions, but having reviewed every piece of information, including this site, I found myself sending a direct message to the poster.

 

[ Hallo. ]

 

“Huh? English?”

 

The immediate response came in unexpected English. Suspicious already, I continued the conversation using my decent university-level English from my British-American literature major.

What I discovered was that there exists a Japanese man with the extraordinary ability to impregnate any woman, just as the article claimed.

This “any woman” included those like me with poor fertility, and he had a track record of getting nearly 100% of such women pregnant.

And his bl00d type was B.

I wondered at first how he could make any woman pregnant. I wondered if they were talking about something like the so-called Chinese martial art of Qigong, or the traditional massage for infertility.

The mention of his bl00d type left me puzzled, but when they sent me the reference video they mentioned, everything became crystal clear.

 

“OH YES!! OH MY GOD!!”

 

The video showed a white woman being relentlessly fucked from behind, her pvssy being pounded mercilessly.

The Caucasian woman with her vibrant blonde hair was thrusting her massive buttocks and br3asts violently as she focused solely on taking the man’s p3nis.

The man she was having s3x with was probably Japanese. A burly, seemingly unrefined college-aged boy was fucking the Caucasian woman in a video without even a mosaic censor.

I’ve been tricked, I thought.

They lured me in with the promise of having a child, then directed me to this obscene adult site. With that realization, I immediately tried to stop the video.

But then…

 

“AHH!! OH MY GOD!!”

 

The Caucasian woman pinned down by the Japanese boy was emitting intense moans. Watching from the outside, I thought, How rough this s3x is! Each thrust carried terrifying force, and the sound of their bodies colliding was equally violent.

Above all, the woman’s voice, which rose in a shrill scream, laid bare the ferocity of this s3x act.

Even a beauty like her would make these sounds when fucked so manfully, I thought. Of course, some of it was probably acting, but professional s3x exists on a completely different plane from what ordinary people like us experience.

 

“AHHH!”

 

The particularly high-pitched female moan told me the boy had come.

As expected, a massive amount of white fluid was gushing from the gap between their joined bodies.

 

(What… is this amount…)

 

The utterly overwhelming sight left me completely frozen. The boy’s cum release was incredibly powerful, as if he was firing bullets of sperm into the Caucasian woman’s body.

Impossible. At first, I thought it might be synthetic. But the woman’s reactions were too realistic for that, and I couldn’t find any evidence that it was fabricated.

The Caucasian woman who had been made to cum was visibly not acting—her orgasm was unmistakably genuine. Her entire body convulsed, then went limp as if collapsing. Her normally composed features twisted with intense pleasure as she surrendered completely to his creampie.

Soon, the male member was withdrawn from their connection. The symbol of masculinity remained stubbornly hard, leaving me utterly speechless.

 

(What… is this…?)

 

First and foremost, I couldn’t help but marvel at its size.

I knew there might be differences between Caucasian and Japanese women, but the sheer audacity of how something this massive could have been inserted was overwhelming. The shaft stood tall and erect, curving backward like a Japanese sword. Though it might sound strange, it was so shiny that I even thought it was beautiful

In terms of thickness, hardness, and length, it was completely different from Takkun’s.

The exposed glans was so magnificent, and as a woman, I knew all too well what role it played in s3x, whether I liked it or not.

The dangling scrotum also looked nothing like the ones I’d seen before. I couldn’t even begin to imagine how much sperm that massive sac could hold.

His face was pure and kind, yet he was attached to something unbelievably magnificent.

This p3nis… maybe—

I shook my head to clear those wild thoughts.

My infertility was my problem. Changing partners wouldn’t lead to pregnancy.

 

“This…”

 

The next document revealed that this Caucasian woman had undergone infertility treatment for three years, discovered she was pregnant two weeks after this s3x act, and hadn’t had intercourse with any other men during that period.

She even attached proof of treatment and ultrasound images from her pregnancy.

In other words, this means any woman could get pregnant from s3x with this boy.

Even I don’t believe such dubious data. But even so,

 

“AHH!! OH MY GOD!!”

 

Before I knew it, I was repeatedly replaying the video.

No matter how many times I watched it, it was incredible.

If a woman were violated this violently, wouldn’t she get pregnant?

Whether a woman gets pregnant or not depends on compatibility with her partner. If Takkun had exceptionally high reproductive ability and could impregnate women with low pregnancy rates—

Such counterfactual speculation is meaningless.

But it’s clear the boy in this video has far superior reproductive ability compared to Takkun.

Just look at this amount of semen. The color is incredibly thick, too, and with this size, it could easily reach the uterus.

A symbol of masculinity that’s completely different from Takkun’s.

If this man’s p3nis…

Somewhere, I was thinking that.

But that could never happen.

No matter how incredible this boy is, I couldn’t get pregnant even after multiple s3x sessions with Takkun. Besides, any child born from s3x with this boy would be mine and his, not Takkun’s.

True, the bl00d type matches Takkun’s.

Even if I did get pregnant, there’d be no proof without a DNA test.

Even if this boy’s monstrous p3nis thrust into me, making me climax as violently as that Caucasian woman in the video, the chances of pregnancy are still higher than not.

I won’t get pregnant.

As long as I don’t get pregnant…

While watching a s3x video, I found myself thinking absurd things.

What if I try having s3x with this guy…

If I don’t get pregnant, it’s just that.

Since I never thought it would work anyway, it would simply end with this boy cumming inside me.

But what if I did get pregnant?

Then I’d finally have the baby I’ve always wanted. The child wouldn’t be related to Takkun by bl00d, but I could carry it in my womb, feeling the pain and reality of childbirth. The baby would be 100% B-type.

After all, Saya-chan herself is Takkun’s child from his previous wife.

Who would be unhappy if I had a child with another boy and secretly gave birth to it as Takkun’s?

In fact, that might make for a more balanced family.

As if reading my inner conflict, a new message arrives.

The sender’s identity—whether Japanese or foreign, male or female—remains unknown. The message, written in simple English, reads:

 

[Only s3x for free.]

 

s3x alone is free.

Meaning no money is needed unless pregnancy occurs.

And then:

 

[Imagine this huge c0ck fvck you hard.]

 

“Huge…”

 

Remembering the p3nis in the video, I involuntarily swallow hard.

Imagine this massive c0ck relentlessly pounding into you—

After being told such things and shown these images, I’m sure there are feelings I’ll never be able to share with Takkun.

Not even with Saya-chan, my precious daughter.

Or with this child, who’s supposed to be born next year—

 

◆　◇　◆

 

(It’s incredible…)

 

When I finally saw the p3nis with my own eyes, I couldn’t help but think that to myself.

In the end, after three months of agonizing, I ended up asking him to help me conceive.

I was surprised by the true identity of the person mediating between us, but when I saw his p3nis in a Tokyo hotel, my eyes widened even more in shock.

It was completely different from Takkun’s.

Seeing his actual p3nis was more robust and raw than the video had shown. Knowing what it looked like when erect from the footage only made its presence more overwhelming.

His p3nis is so amazing.

The boy’s demeanor was so timid and slightly unreliable that it made me think this way.

When I saw him hiding his lower body, he looked like a cute college student.

He’d seemed intense in the video, but maybe there wasn’t anything to fear.

With that thought, I knelt at his feet and took his still-soft member into my mouth.

 

(Not erect yet, but it’s still so big…)

 

It was obvious just by looking, but when I put it in my mouth, his p3nis felt substantial and surprisingly heavy.

I couldn’t possibly take it all the way in, and even moving my tongue around it was a struggle. With Takkun, this kind of thing would never happen. Just holding it in my mouth made me worry my jaw might dislocate.

 

“Mmm, mmm—”

 

Still, I didn’t feel any discomfort at all. I’m sure that’s because I’d mentally rehearsed this moment countless times before coming here.

From the moment I decided to make this request of him until this day finally arrived, I’d imagined our encounter countless times.

How could I satisfy that formidable p3nis of his? As someone with limited sexual experience, would I even be able to make him come?

These thoughts led me to fantasize about child-making s3x with this man.

Child-making…

The word alone made me feel guilty toward Takkun.

Yet at the same time, I couldn’t deny the heat pooling in my abdomen.

Once a body has been charged with magic, it’s not so easily reclaimed.

His s3x and that formidable p3nis must be magical at this point. The fact that countless women before me had been impregnated by him suddenly seemed plausible.

The moment I first saw that video, I was undeniably overwhelmed by his powerful p3nis and powerful s3x.

 

“Ah, Ms. Asuka, could you sandwich me with your… thing?”

 

“S-sandwich? With my br3asts?”

 

Following his instructions, I performed an act I’d never done before—titjob.

My chest isn’t small by Japanese standards, but his p3nis overwhelmed even that.

So hot.

And what kind of hardness is this?

Can something this massive fit inside me?

Despite these doubts, I focused intently on moving my br3asts. The magnificent glans sliding in and out of my cleavage overwhelmed me both visually and smell-wise.

 

(This smell… It’s numbing my mind…)

 

The smell of his p3nis was intense.

It was fishy, ​​or maybe manly.

Yet paradoxically, it didn’t feel unpleasant.

Instead, I found myself strangely compelled to keep smelling it forever.

His p3nis inside my chest was so hot that I feared my br3asts might get burned.

 

“Does it feel good…?”

 

Despite being a married woman, I couldn’t help but try to gauge his mood.

I had no intention of doing anything beyond child-making with him, but seeing such a robust p3nis, I couldn’t help but wonder if he could find pleasure with someone like me.

 

“It feels good… Can I cum in your mouth?”

 

His words made my heart flutter.

But I can’t do that. If I swallow his sperm now, it will just be a cheating blowjob.

 

“No. You have to pour all of your semen into my uterus. That’s the contract.”

 

As I spoke, a warmth spread through my abdomen.

It’s as if I’m begging him to cum inside me, and I’m overwhelmed by a sense of shame.

 

“Please, hurry and fill my pvssy with your cum.”

 

In the end, having lost all sense of propriety, I throw myself onto the bed and spread my legs obscenely.

My intention was to finish making a baby quickly, but it feels like I’m desperately craving his thick member. And my face heats up

Then…

 

“I’m going in, Miss Asuka.”

 

His formidable c0ck finally locks onto my entrance.

I thought I was prepared for this, but now that insertion looms before me, I find myself terrified.

It was so strong, so curved, was it okay for me to accept his thing like this?

Is it really okay to have s3x with him under the pretext of having a baby?

By the time I realized this, there was no turning back.

The truth stared me in the face—my dripping arousal and pounding heartbeat made resistance futile.

I had no choice but to accept it.

Resigned, I desperately tried to calm my racing heart as I met his gaze and nodded.

Please, insert your c0ck into my pvssy.

The college boy accepted the lewd plea of the married woman without hesitation.

His hard glans pried open my entrance and, following the slimy love juice, entered my v4g1na.

And then—

 

“Ahhn—!”

 

An impossibly thick p3nis invaded me.

What is this?

The girth, the hardness—it was on another scale entirely.

The length, the upward curve, the size of the head—everything about it defied comparison.

It was nothing like Takkun’s.

The epitome of maleness.

The alpha among alphas.

This man’s c0ck had plunged deep into me in one brutal stroke.

 

(What is this p3nis…? Why is it so full…?)

 

When his p3nis first penetrated me, I must admit it hurt.

I’d never taken anything this big into me before in my entire life.

But as he maintained that position for several minutes, I gradually became acutely aware of the presence of this p3nis inside me.

I’d seen his impressive shape countless times in videos.

The magnificent mushroom cap stretched taut.

The merciless girth forcing open my vaginal walls.

The length that reached my deepest depths with just a shallow thrust.

When he penetrated my pvssy, I thought my life was over.

Not because of the infidelity,

But because I knew there was no going back after experiencing such a monstrous p3nis.

Everything about it was different from Takkun’s.

In every aspect – thickness, size, length, hardness, the way his glans protruded, the upward curve, even the size of his scrotum – it represented an unknown, uncharted virility beyond anything I’d ever experienced.

Can a p3nis reach this deep?

Can such a protruding glans ever firmly grasp my most sensitive spot?

I just wanted a child.

That excuse no longer worked. If I was penetrated by such a strong p3nis, it was obvious what would happen to me after that.

 

“Ahh… Asuka, your pvssy’s so tight, it feels amazing…”

 

His words make me feel my inner walls clench involuntarily.

It’s not that my pvssy’s tight—it’s your c0ck that’s too big. Even this feeble retort can’t save the sense of blessed connection I felt with him.

From the start, I didn’t come here for pleasure.

The argument itself is meaningless. The moment his thick shaft breached me, I lost all capacity to protest.

All that remains is to become prey to his existence.

To be relentlessly fucked by his desires, my pvssy churned without end.

 

“Ahh!”

 

He began thrusting relentlessly, his impossibly thick c0ck plunging deep inside me. Each movement stretched me beyond belief.

This will definitely change the shape of my pvssy.

Even without getting pregnant by him, I doubt my stretched walls could ever return to their original form.

 

“Ahh! Ahh!”

 

I wasn’t consciously making these sounds. They erupted from me involuntarily. With every forceful penetration of his overbearing c0ck, with every scrape of his engorged glans against my inner walls, it was as if I’d been programmed like a robot. Sounds I’d never uttered during s3x with Takkun bubbled up from the depths of my belly.

It felt incredible—

This forced s3x, where a man brutally pounds me, where a c0ck thicker than my husband’s ruthlessly stretches my pvssy—it’s unbelievably good.

 

“Ah! So rough! I’ve never experienced s3x like this!”

 

Each thrust felt otherworldly. Never in my life had I experienced such intense s3x.

Trapped firmly against his muscular body, I couldn’t catch a breath as his piston-like thrusts continued relentlessly, like a wild beast in heat.

Worse still, that thick c0ck scraped against the inside of my pvssy with every movement, stealing away all coherent thought.

There was no resisting.

How could a delicate girl like me possibly fight against a grown man?

With my pvssy firmly clamped around his sturdy c0ck, there was nowhere to escape the overwhelming pleasure.

This was truly the climax of the first volume.

If this man ever took our s3x seriously, I’d be utterly helpless to resist.

The overwhelming sensation might even blow a fuse in my brain.

 

“Ahh, Asuka, that feels so good!”

 

His voice was gentle yet pitiful, but his thrusts were pure beastly. Each powerful stroke drove his robust glans against my cervix, sending me into momentary trancelike states.

 

“Oh♡ It’s amazing♡ It feels so much better than Takkun’s s3x♡♡”

 

I knew I shouldn’t say it, but the words escaped involuntarily.

I can’t take it anymore.

This man’s s3x is definitely more pleasurable than Takkun’s.

With such an incredible c0ck, how could I not feel this good?

 

“Ahh! My pvssy craves your semen!”

 

Even I could feel my uterus descending lower.

It was an experience I had never had during s3x with Takkun.

My body instinctively submits to the man, experiencing the pinnacle of feminine ecstasy.

 

“I’m going to cum inside you, Asuka!”

 

“Ahh! Comeee!”

 

Far from any refined intimacy, we’re locked in a sweaty, primal tangle.

Driven to the limits of pleasure, we’ve become nothing but a pair of rutting animals.

It’s as if our bodies instinctively know this is the most pleasurable thing in the world.

 

“Ahh! I’m cumming!”

 

At his shout, his massive c0ck swells even larger.

My instincts – my woman’s instincts – brace involuntarily as I realize this is preparation for ejaculation, for impregnating this married woman.

And then…

 

“Ahh—♡♡♡”

 

His swollen glans, pressed against my cervix in a final, intimate kiss, erupts with an unbelievable torrent of semen.

Honestly, I thought my uterus might rupture. The way men’s bodies can store so much semen in their testicles—this whole reproductive system is fundamentally different. The bullet-like semen slammed directly into my uterus, and every time it did, I was hit by an overwhelming pleasure that was enough to make me faint.

I really lost consciousness.

Such overwhelming ecstasy, such profound pleasure.

My mind goes completely blank, leaving only his c0ck to occupy my thoughts.

This is undoubtedly the most pleasurable s3x I’ve ever experienced.

The most blissful moment of my life.

 

(It’s far beyond anything I could have imagined…)

 

Impregnation.

Child-making.

Cheating s3x.

None of that matters anymore.

When a woman’s womb is flooded with this much semen, a woman can’t help but be happy.

It’s not about getting pregnant. True happiness comes from having your womb filled by a sturdy c0ck.

I’ve always wanted this feeling.

Even if I were to get pregnant from this s3x and eventually give birth to the child I’ve always dreamed of, I doubt I’ll ever experience anything that surpasses this feeling.

I want to stay like this and be his sperm tank.

I want my uterus to receive all the sperm his balls produce.

 

“Ah! Aahhh!”

 

As if granting my desire, he begins another relentless thrust without pause.

Even after such overwhelming pleasure, the ecstasy his p3nis brings remains unchanged. With his sturdy member inside me, I have no choice but to surrender completely.

Wrapping my arms around his broad back and entangling my legs around his muscular hips, I offer my entire being to him – my pvssy, my lips, my very soul – begging for kisses that melt me.

 

“Mmm… Mmm!”

 

He doesn’t miss the invitation. His tongue entwines with mine in an unbelievably skilled deep kiss, melting my mind as thoroughly as his c0ck melts my pvssy.

Both the fucking and the kissing feel so good I might die.

With him, I’d let him do anything to me.

The cervix was relentlessly pummeled by his vigorous glans, while the uterus overflowed with his seed.

 

(I guess that means I’m pregnant now, right?)

 

Though lacking scientific evidence, a woman’s primal instincts told me conception was inevitable after such intercourse.

After all, this was the first time my uterus had descended to meet climax with anyone but Takkun.

This marked my first sexual encounter with this man.

From here on out, it’s all just entertainment.

A pure act of pleasure – nothing more than using his formidable c0ck to satisfy myself.

I’m sorry, Takkun.

From this moment on, I’ll be cheating in earnest.

Since I’ve already done my part for baby-making with him, doesn’t that mean I deserve some pleasure-driven s3x too?

Don’t worry, I’ll end it here.

Tomorrow we’ll return to our loving couple act.

So please, just for tonight, forgive me for being this man’s slave to his thick c0ck.

After all, I came here today solely to have s3x with him…
