"Creating an oral pussy...!? What in the world..."
Before I could even fully harbor such a question,
Tony hyung commanded Lina in an excited voice.
"Hehehehe. Lina, relax your neck."
Into Lina's mouth, which hung open with drool spilling out,
Tony hyung began to slowly push his fully erect cock inside.

Fellatio—caressing a cock with her mouth—was familiar territory for Lina.
But this time was different.
Tony hyung's large cock did not stay only within Lina's small mouth.
Savoring the hot interior of her mouth, he was steadily pushing his cock deeper and deeper, nearing her throat.
In that instant, a panicked scream erupted from Lina's mouth.
"O, oh... kh... hup!"
But that sound, unable to escape outside, scattered into muffled garble.
Tony hyung, paying no mind to Lina's reaction, pushed himself deep into her throat.
And as if to feel Lina's pulse, he stayed perfectly still.
Holding the struggling Lina by the hair, he was literally handling my wife's precious throat like an onahole.

"Oop,... oooup.,,,!!"
Drool spilling from her lips, Lina thrashed for a moment in the unfamiliar terror of suffocation. But soon, she began to gradually accept Tony hyung's cock.
Squelch, squelch.
Tony hyung was gently rubbing against Lina's throat, carefully and kindly regulating the pace so that she would not be seized by the fear of asphyxiation.
Just as one would softly rub a cock around the entrance of a pussy before thrusting it inside.
That was how he painstakingly burrowed deeper and deeper.
Kindly, he began to stain Lina's throat with himself.
'What is this... turning a throat—not even an erogenous zone—into a pussy?'
I had been harboring such a question, but in that instant, I could not contain my shock.
Because Lina's pussy, which was tightly gripping my cock, had begun to twitch in rhythm with Tony hyung's kind and gentle pistoning.
Twitch, twitch.
"Oop, oooup. Hooup-♡!!"
Lina had gradually begun to feel pleasure from the stimulation plunging into her throat.
The lewd evidence proving it was gushing out hotly.
Drip drip drip.
Squish, squish. Squish.
"Good heavens..."
Lina, who should have been in pain, was feeling pleasure.
"Hehehehe."
Tony hyung, looking at me with a mischievous face, brimming with smug satisfaction.
Looking at him and at Lina, who was beginning to feel it with only her throat, I couldn't hold back my admiration.
"Haup, haaup. Haout-♡!!"
With her mouth completely blocked, Lina couldn't even let out a proper moan.
But as her entire body trembled, endlessly squeezing my cock, she simultaneously began gushing out increasingly copious and hot pussy juices.

That her lewd throat was at some point becoming yet another pussy...
That she was becoming a lewd seductress, suited to receiving two men at once and serving them...
Flutter, flutter.
Twitch, twitch.
Unable to utter a single word with her mouth blocked, Lina was confessing her dramatic bodily transformation to me without pause—through her lewd pussy that was contracting like crazy.
Having confirmed Lina's face melting away as her throat was ravaged, Tony hyung, as if boasting, began lecturing me once again.
"Louis, Louis. How is Lina's pussy right now? She's started getting all sticky and in heat, hasn't she?
Hehehe.
An oral pussy truly does exist.
Hahahaha."
Squelch, squelch.
"Haup, haaup. Haout-♡!!"
Tony hyung continued speaking while meticulously training Lina's oral pussy.
"When strong pressure and rhythmic stimulation are applied to the throat,
the human body reflexively creates tension and relaxation throughout the entire pelvic floor muscles.
If you completely block the throat with a cock until she nearly suffocates, and then let her breathe at the last possible moment...!!"
Mid-sentence, Tony hyung suddenly plugged Lina's throat completely with his cock.
Then Lina's face flushed red and she began streaming thick drool.
"Uuuup...♥♥ Uuk! Haout-♡!!
Haup, haauup. Heuguk-♡....!!!!!!"
"Hehehehe."
At the perfect timing, Tony hyung slipped his cock slightly out of Lina's throat.
"Haa, ha. Haa..."
Drenched in sticky, milky-white saliva and tears that had risen from deep in her throat, Lina was gasping for rough breaths.

"Oop, oooup. Hooup-♡, haa, haa, aaaap.♡!"
From her pussy—which ought to have been in pain—sticky pussy juices gushed out in large quantities once again.
Because of that, my cock, which had been inside Lina's pussy, was pushed out with a slick slide.
Both Lina and I were flustered by this situation that defied common sense.
But Tony hyung calmly continued his sex education.
"A woman is psychologically and completely subjugated to the man who controls even her breathing.
After that, the lewd bodily reactions that occur automatically by reflex are perceived as pure pleasure.
Right now, I am imprinting those things onto Lina's nervous system...
It's a highly difficult task requiring extremely delicate and sensitive control, hmm..."
As if too proud of himself, the hyung who had been chattering on boastfully resumed Lina's oral pussy training.
Squelch, squelch.
"Haup, haaup. Haout-♡!!"
Tony hyung repeated the same procedure over and over.
Slowly, gently—but extremely persistently—he was training Lina.
"Heung.. oot.♡, hu, hua.. hoout-♡!!"
The pitiful Lina was no longer in pain.
Her completely loosened throat had become Tony hyung's onahole, and with even control of her breathing stolen from her, she was utterly subjugated to him.
"Eung.. heup...♡, haaup. Hoout-♡!!"
Psssshh♡
Pssht pssht pssht
Drip, driiip.
She was simply leaking lewd pussy juices without cease, her pussy fluttering endlessly.
Lina was now having sex with Tony hyung not with her actual vagina, but with her throat.
Today, my wife had gained a new lewd pussy.
While I was lost in those ecstatic and depraved thoughts, Tony hyung woke me.
"Now, Louis, put your cock back into your wife's pussy, and this time rub with the sensation of gently caressing the inner walls of her vagina. Just like me...!"
Not wanting to lose to the showboating Tony hyung, I shoved my cock back into Lina's pussy and began slowly moving my hips, following the movements of the skilled trainer.
Not violent pistoning from the start, but gently—with the sensation of caressing Lina's inner vaginal walls.
Then I gradually began increasing the pace.

And the effect was tremendous.
"Hup, haguk. Haout-♡!!"
As if electric current were running through Lina's brain, she began trembling all over.
As both her throat and pussy began to be ravaged simultaneously, Lina's eyes began to roll back.
With her mind having gone completely blank, she was panting like a female animal faithful only to instinct.
Tony hyung spoke with a satisfied expression.
"Oh, her throat is squeezing down tight...!
Louis...!!! Lina's pussy is also squeezing, squeezing tight right now, isn't it?
The lewd bitch who has grown another pussy can't contain her joy and is cumming without cease...!!!"
There was a saying: if you want to determine whether a woman is truly feeling an orgasm, check her moans.
Those pretty, buzzing sounds are fake, they say.
A woman overcome by real waves of pleasure has no time to care about appearances and lets out sounds close to shrieking, they say.
Just as one loses reason amid extreme pain and lets out shrieks,
when plunged into extreme orgasm, they likewise lose reason and shriek.
My Lina was showing me exactly that appearance right now.
Though her throat was blocked...
In the brief moments when Tony hyung's cock would slide in and out and her airway would open, shrieks the likes of which I had never heard before were bursting from beautiful Lina's mouth.
"Haaak... hoooooh! ♥ Aaaah!! Ooh-hok!!♥"
It was different from the climax brought by caressing.
The climax now was on an entirely different dimension from back then, when she had still held on to some semblance of reason.
Lina's entire nervous system—which had been trembling precariously, on the verge of bursting as pleasure piled up layer upon layer through caressing—had now gone completely berserk from the tremendous stimulation.
All over her body, sweat carrying an indecent scent began pouring down like rain, and from her pussy, so much sticky juice was gushing that it kept pushing my cock out.
Squelch, squelch.
Twitch, twitch.
"Hup, aguk. Haout-♡!!"
Screech, screech.
Twitch, twitch.
Pssht pssht pssht, tsut tsut, tsssss.

Every time I rubbed Lina's inner vaginal walls with my cock, her body twitched as if convulsing.
That stimulation alone would have been overwhelming, but with Tony hyung relentlessly plunging into her mouth as well, Lina could barely even stand on her own strength.
But Lina's body was transforming ever more lewdly and seductively.
Tony hyung could not contain his admiration at that indecent change.
"Hooh, hooh, hooh.
... Ohh, Lina's throat is thrashing around incredibly...!
Damn, to think that Lina was such an incredible talent. I am truly lamented..."
Squelch, squelch.
Twitch, twitch.
Screech, screech.
"Hup, hoout♡, haout-♡!! Aaaaah...!!!"
Twitch, twitch.
Screech, screech. Screech, screech.
Pssht pssht pssht, tsut tsut, tsssss.
Bang, bang, baaang.
"Haaak... hoooooh! ♥ Kuuugh! Hogogok!!♥"
Endless pistoning.
Oral pussy and real pussy—two men were mercilessly plunging into Lina's body from front and back.
As their rhythms gradually fell into sync, Lina's body was being roughly rocked back and forth.

Perhaps due to the influence of female hormones released by the extreme climax, her voluptuous breasts seemed to have swollen far more lewdly and heavily than before.
Jiggle, jiggle.
Every time Lina's body shook, her heavy breasts swayed indecently.
And that itself became yet another pleasure for Lina, scorching her mind white.
"Hup, hoout♡, haout-♡!! Uuuup...!!!"
Tony hyung, his whole body now drenched in sweat, slowly smiled and opened his mouth.
"Louis, I think it's time to wrap up soon. If we keep going, Lina's body truly won't be able to endure it.
That's all for today...!
This sensation that has been imprinted into her body today will not be forgotten, and when we re-imprint it next time we play, the perfect oral pussy training will be complete.
Now, here I come. Lina...!!!"
Tony hyung began to release his rank semen.
Semen he had accumulated through a month of abstinence.
All of that thick semen was being blasted into my wife's throat.
Gulp, gulp.
Tony hyung, ejaculating without pause, endlessly.
Gulp, gulp.
Gulp, gulp.
"Kheup, heup...♡ gulp, gulp. Hoout-♡!"
The semen she couldn't swallow all poured down from the corners of Lina's mouth.

The hyung's semen, aged for a month, was truly appalling.
It was incredibly viscous and sticky, as if it had chunks mixed into it.
Lina was receiving all of that rank, intense male essence.
She didn't even gag.
Lina, completely in heat.
Lina, her entire body and even her mind subjugated to Tony hyung.
My woman was willingly drinking down that rank semen of another man.
"Haak... haa, haa."
A sudden, maddening sense of depravity washed over me.
Lina, who had never eaten my semen.
No...
She couldn't eat it.
She had tried several times at my persistent requests, but each time she would gag and give up, saying she was sorry.
But now...
Lina, without any aversion whatsoever,
was receiving that stuff—aged for a month and incredibly rank—with an ecstatic expression.
Gulp, gulp.
Gulp, gulp.
That wasn't all.
As if intoxicated by the scent and taste of that incredibly thick semen, Lina's pussy began contracting like mad, squeezing my cock tightly.
Twitch, twitch.
Pssshh, keeeek.
"Haaak....hoooooh!
Haa, haa, aaaah.♡! Huaaah! Hoout-♡!"
"Ah~♡ Aahng~♡ I'm cumming~~♡"
Ha...
Lina was now climaxing in an unsightly display.
As if the development of her oral pussy wasn't enough...
She had now fallen into a bitch who would pant and cum just from drinking semen.
Today... my Lina has developed an oral pussy.
