How Using My Oppai Skill to Enlarge My Sister’s Breasts Led to Building a Harem - Chapter 54: Father-in-Law's Request 3

Chapter 54: Father-in-Law’s Request 3

<Saionji Kazuma’s Perspective>

I’m a man born into the fairly historic prestigious Saionji family.

However, I was sickly from birth, physically weak, and unable to sexually satisfy women.

And now at 46 years old, my body—perhaps due to aging—has lost its function as a man.

But Carla, the woman I love, is 29, in her sexual prime. Having become impotent, I couldn’t possibly satisfy her, and I harbored awkward feelings about it.

That’s when I learned that my son-in-law, my daughter’s husband, appears as a male actor in adult films.

I was torn. Carla had told me she’d had physical experiences with him several times, but I’d accepted that as the past.

(But what a magnificent physique)

My son-in-law is nearly 20cm taller than me at 170cm, and has a solidly built body with bulging muscles from rigorous training.

Incomparable to my withered branch-like thin body—the thick physique of a superior male.

And furthermore—my son-in-law possesses a truly remarkable—huge member.

In fact, I can clearly see it in the footage before my eyes right now.

“Haahn♡ More… thrust with that thick thing~~♡”

While watching the footage I’d asked him to film, I was overwhelmed by the intensity of the sexual act.

“Your pussy’s gripping so tight, Carla-san!”

Pashun! Pashun! Pashun! Pashun!

Though it’s strange for me to say this when I asked for hidden filming, I hadn’t anticipated such intense activity.

(I thought it would be enough if Carla’s body was satisfied, but…)

Perhaps my son-in-law’s massage was too effective—Carla made a face I’d never seen before and desired intercourse with him.

The result—was this.

“Hngh! Hngh! Hngh! Does it feel good, Carla-san?”

Pashun! Pashun! Pashun!

“Nhohooo~♡ Good… feels good~~♡”

My son-in-law’s excessively thick and magnificent member violently thrust up from below into my beloved woman’s precious place—penetrating to her deepest depths.

(Was intercourse always this intense…?)

Bodies colliding with an intensity absolutely impossible for my frail physique.

Carla’s body continuously thrust upward as if floating in air.

Sweat flying, female flesh swaying lewdly, obscene liquid frothing and leaking from their union.

“I’ll go a bit faster now”

Pashu! —Pashun pashun pashun pashun♡

“Hyah, ahh, I’m coming… ahhh, already… coming coming coming~~… ah♡”

Carla climaxed.

My son-in-law so easily gave her an orgasm I’d never once managed.

“Auh… my body’s floating…♡”

“You’re wonderful, Carla-san”

“Hyahn♡ Don’t thrust yet~~♡”

Carla’s body trembles, swaying on waves of pleasure. Yet my son-in-law continues attacking her with a relaxed attitude.

(This is… real intercourse… what they call sex)

Completely different from the procreation I’d been doing until now.

Compared to this, my acts are mere child’s play.

“Ahhh♡ …coming coming coming, again… I’m coooming~~~♡”

Carla’s body convulses with a large twitch, her hips shaking pathetically.

“Amaazing~~♡ This cock is too amazing”

The woman there was a Carla I’d never seen.

Dominated by sexual desire, a woman devouring pleasure as if exploding with lust was there.

(What in the world…)

Having always had weak sexual desire, I’d never watched such footage before.

So I didn’t know.

What kind of expression a woman makes—when she feels pleasure…

(What… is this what obscene means?)

Yes, obscene. A man and woman copulating like animals, devouring sex.

It was so vulgar, savage, pathetic—and beautiful.

“I’m going seriously now”

My son-in-law said that… and lifted one of Carla’s legs, laying her on her side.

Dochu! —Pahn♡ Pahn♡ Pahn♡ Pahn♡

“Nhooooo~~♡ N-no… that’s too much~~~”

My son-in-law swung his hips at tremendous speed from behind while holding one leg, pounding the depths of Carla’s genitals.

That movement was exactly like a wild animal’s—the appearance of a strong male who’d dominated many women.

“Ohhhhh♡ Amazing, amaazing~~n♡”

My son-in-law’s thick, long shaft repeatedly enters and exits Carla’s genitals.

Simultaneously, his huge ball sack swings, slapping against Carla’s outer genitals.

Pahn! Pahn! Pahn! Pahn!

“The first shot’s coming soon! I’m releasing it!!”

Saying that, my son-in-law thrust his hips forward with all his might, pushing that massive penis into the beloved woman’s womb.

At that moment, I came to my senses—and reflexively shouted.

“!?… W-wait, son-in-law!”

Pahn! —Spurrrrt♡ Spurt, spurt, spurt♡

“A-ahhh… what have I…”

This footage is from after the act has already occurred, so stopping it is meaningless, but…

Still, my heart wavered at a far stronger male than me releasing his seed inside the woman I love.

(Carla is happy. Then it should be a good thing…)

I was the one who asked my son-in-law.

To give Carla happiness as a woman.

To lend that magnificent body in place of pitiful me who’d lost male function…

“I’ll get pregnant… ahhn♡”

What a happy face.

“It’ll be fine if you use contraception afterward, Carla-san”

“R-right… yeah…”

Carla’s tone made me think she might actually want a child.

Noticing this, my son-in-law opened his mouth toward Carla.

“We can’t make a child behind Father-in-law’s back, can we?”

“Ah… that’s right… But—”

Carla’s face clouded, her mouth working as if struggling to say something difficult.

Still, deciding she must say it, she opened her mouth after a pause.

“Kazuma-sama… doesn’t seem to get excited by my body anymore…”

Thud

I’d unconsciously stood up from my chair.

The impact made my beloved coffee cup ring with a jarring sound, but it no longer reached my ears.

“N-no, that’s wrong… Carla! It’s not like that…!”

I desperately made excuses to the screen.

It’s not that there’s no love.

The first night after our reunion… we slept embracing naked, but the lack of activity was my body’s problem.

(Carla… I—)

With anguished thoughts, I gazed at Carla on the screen.

Then, the one who understood those thoughts—was my son-in-law.

“That’s not true, Carla-san. Father-in-law loves you from the bottom of his heart…”

“Eh?”

“M-my son-in-law…”

My son-in-law gently embraced Carla and told her how much I think about her.

That because his male function doesn’t work, he even worries about her female needs—he explained that.

“I see… I…”

“Father-in-law loves you more than anyone. Otherwise he wouldn’t have asked me to be your sex partner”

Carla’s misunderstanding melted away.

Her expression was the happy face of a beloved woman—and I understood it was directed at me.

“My heart… belongs to Kazuma-sama”

(Thank you, Carla. My heart is yours too…)

Now, through the screen—our hearts connected.

Hearts that had been apart for so long, finally.

However, a woman’s body is honest.

“Auh♡ No… I’m coming… uuu~~♡”

A body filled with love was guided to the peak of happiness.

“Carla-san… please think of me as Kazuma-sama and feel good”

“Ahh! Kazuma-sama… Kazuma-samaaa…♡”

My beloved Carla keeps calling my name.

While satisfying female desire with another man’s body, she continues conveying love to me.

“Carla! You’re… beautiful. Truly, beautiful…”

Before I knew it, I was shouting that.

Pahn pahn pahn♡

“Ahh♡ Ahhh~~…♡”

My son-in-law began swinging his hips as if matching Carla’s demands.

Pahn, pahn, pahn, pahn!!

“Ohhhhh~~♡ Kazuma-sama’s cock… pounding, so amaazing…♡”

“Hngh! Hngh! Hngh!… Inside Carla is also writhing amazingly”

“Oho♡ Ohhh… n”

Carla seeks me, and my son-in-law violently thrusts in his massive penis.

Before I knew it, I was drawn into that perverse scene—and excited.

“Kazuma-sama♡ Kazuma-sama…♡ Ahh… good~~♡”

“Guuu…! Carla…! I’m releasing it!”

“Release it…! Impregnate meee~~♡”

As Carla screamed, the massive penis began ejaculating—and her belly squeezed tight♡.

That was a female’s instinct seeking seed, proof of Carla’s love seeking my child.

Throb♡ Throb♡ Throb♡ Throb♡

“Haa… haa… Kazuma-sama’s baby…♡”

Throb♡ Throb♡ Throb♡

Carla receives the thickly packed semen with a dreamy, melted expression.

(Carla… I…)

I was convinced Carla had gotten pregnant by a man other than me.

But that’s my son-in-law doing it in place of me who’s already dried up.

“I love you… Kazuma-samaaa”

“Ahh… I love you too… Carla!”

We exchanged love through the screen.

While watching seed continue being pumped throbbing from that massive member…

※

“Thank you, son-in-law… I’m satisfied…”

As if to cool my excited head, I sip the cooling coffee.

Them making a child is unexpected, but if Carla wants to give birth, I intend to acknowledge it.

Because even if the seed is different, it’s a child conceived through the love between Carla and me.

I reach out to close the screen while sighing deeply—but

“Why… is there still more?”

Looking closely, the video’s playback time had only reached halfway.

While thinking this strange, I stare at the screen and…

“Then, shall we do it here next, Carla-san?”

“Nhaaah~♡ Auh!? Ah♡ Ah♡ Ahhh~~♡”

My son-in-law started up again on the sofa as if the real thing was just beginning.

“What… virility… gulp…”

Is this what a real man is—unlike frail me?

The strong male on screen transforms my beloved woman into a female, drowning her in a swamp of pleasure.

“I’ll properly satisfy all that’s been building up…”

“Ah, heeee~~♡”

After saying that, my son-in-law made Carla climax many more times—and performed intercourse until she lost consciousness.

※

Days later.

“Thank you, son-in-law…”

“Huh?… Um, I… didn’t I overdo it?”

I was thanking my son-in-law at the estate I’d visited again.

Certainly, he may have overdone it. But it wasn’t with ill intent.

Because of youth, because of his own strength.

That can’t be helped.

Besides, I was the one who asked him to satisfy her so Carla’s desires wouldn’t explode.

“No, it was very good. Carla was happy too”

“I see…”

Since my son-in-law looked apologetic toward me, I patted his back to convey I didn’t mind.

That must have gotten through, as he smiled refreshingly like a young person and showed a relieved expression.

“I’m glad I could be of service, Father-in-law”

“Yes, truly. So—”

“?”

“—Please do it again, son-in-law”

“Whaaaat!?”

My son-in-law was shocked and shouted at my words.

But my mind won’t change.

Because—wanting to see more of my beloved woman’s beautiful form is only natural.
