15.
"Oh my. Master-nim. Look over there."
Gahyeon acted coyly as she pointed at An Hyeonwoo's dick.
"Getting hard while watching your fiancée being taken away, that's so pathetic and disgusting."
"Indeed. With something that small, I doubt it could satisfy any female."
"What would a low-class, utterly worthless male who can't even bring happiness to a female's womb know? That's why, instead of respecting a superior male like you, Master-nim, he looked down on you and disregarded you, only to end up looking like that in the end."
Gahyeon pulled out the cock as semen dripped from her pussy.
She slowly knelt down and pushed her head into my groin.
"Then... to the wonderful Master-nim's cock that made my womb tingle...♥ To cock-nim who gifted plenty of cute baby seeds to this female's womb, I'll provide mouth-pussy kiss service♥♥"
The tip of the long shaft, the broad and large glans, slipped smoothly into her mouth.
"Mmmph...♥"
Jjook♥ Jjok♥ Jjoo-ok♥ Jjooo-op♥♥♥ Jjyububup! Jjyubububup!!!
"This time, on Master-nim's balls that are full of baby seeds...♥♥ I'll give you a lewd kiss service...♥♥"
"Aahm..♥ Aheum..♥♥ Eum..♥♥ Uuu-eum..♥♥♥ Eum..♥♥"
Jjok♥ Jjook♥ Jjok! Jjoo-ok...♥ Jjok♥
The lipstick kiss marks from Gahyeon multiplied across the huge black cock and dark balls.
Gahyeon continued her service while swaying the cock back and forth as if showing it off to An Hyeonwoo, occasionally shooting a sharp, provocative glare at An Hyeonwoo who was watching us.
Looking at Gahyeon, An Hyeonwoo could only tremble with his rock-hard dick.
"Come here."
As I grabbed Gahyeon's head while she was trying to take the glans into her mouth again and pulled, it slid deep right into her mouth-pussy hole.
"Uphuphuph...?!??!"
"Our Gahyeon, do you want to mate mouth-pussy style with Master-nim?"
Gahyeon smiled bashfully in an overtly deliberate manner and nodded her head.
I grabbed the back of Gahyeon's head firmly and thrust my hips forward with all my might.
"Uphuphuph...!!"
I could feel the glans and the shaft roughly scraping past the roof of Gahyeon's mouth.
After pulling it out once more,
Thrusting straight back in, ssuu-uk!!!
"Mmmph...!! Eum♥ Oong! Oong♥ Mmph♥♥♥"
Ssuk! Ssuk! Ssu-uk! Ssuuu-uk!!!!
"Hey, Hyeonwoo. Your fiancée's mouth-pussy is fucking amazing. The suction is seriously insane. Ah~. Feels so good."
I picked up the pace of my hips.
Ssuk! Ssuk!! Ssu-uk!! Ssu-peok!! Ssu-peok!! Peok!! Peok!! Peok!! Peok!!!
Like a valiant spearman, the glans mercilessly stabbed into the roof of her mouth and throat.
"Oong♥♥ Eup♥♥ Uphuphup♥♥ Uhu-eup♥♥♥ Mmmph...♥♥♥ Eup♥"
"You lewd bitch! Getting turned on while having your mouth-pussy ravished in front of your husband, you hopeless slut!! Tighten that throat-pussy tight!!!!"
Even though she was suffocating, Gahyeon did her best to suck on the cock packed full inside her mouth and throat, bringing on the urge to ejaculate immediately.
"I'm cumming!! Take it all with your defeated female mouth-pussy!!!"
Swaaaaaaaa!!!!!
"Mmmph...!!! Cough!! Ke-heuk!! Keo-heuk!!!"
Gahyeon, who admirably tried to take the ejaculation deep inside her throat, ultimately couldn't endure it and spat the cock out.
In the end, cum splattered messily all over Gahyeon's body and dress.
Semen was still trickling out of the cock bit by bit.
Gahyeon placed the engagement ring she held onto her palm and caught my semen right on top of it.
Gahyeon took off the semen-stained dress and rolled it up carelessly.
"Hyeonwoo. The very fact that I received this from a pathetic male like you is just horrifying."
After gouging An Hyeonwoo's heart, Gahyeon shoved the cum-soaked dress and engagement ring into the trash can.
"How was that? Did I do well, Master-nim?"
I stroked Gahyeon's head as she looked eager to be praised.
"Now turn around."
"Yes♥ Master-nim♥♥♥"
Grabbing Gahyeon's breasts in both hands as she turned around and leaned against me, I kneaded and squeezed them as if imprinting whose possession the female before me was.
"Ahng...♥ More...♥ Please touch me as much as you want, Master-nim...♥ Because my body belongs to Master-nim now...♥ Because my heart also belongs solely to Master-nim...♥ Please fuck me..♥ to your heart's content...♥♥"
Gahyeon also felt lewd pleasure from having her breasts kneaded, making it unmistakably clear to An Hyeonwoo whose female she belonged to.
"Watch closely. An Hyeonwoo."
An Hyeonwoo glared at me with wide, livid eyes.
"See what kind of expression a female makes when feeling true pleasure and happiness."
Pu-uu-uk!!!!
"Euheueung...!!! It's so deep...♥ Because Master-nim's is so huge...♥ So deep inside...♥"
Ssu-uk!! Ssuuu-uk!!!
I kept thrusting deeper inside.
"Eung...♥ Heueung...♥ Haeung...♥♥♥"
Teok!
The glans reached Gahyeon's deepest and most precious spot, a place that could never be touched by An Hyeonwoo's tiny thing.
"Ahat...♥ Ah...♥ My womb got kissed by the glans...♥♥ Master-nim's glans is so cute...♥♥"
"Do you like it when I press firmly against it like this?"
"Yes..♥ I love it, Master-nim♥♥ Please torment my womb all you want...♥♥"
Kkww-uk! Kkww-uk!! Kkuguguguguk!!!
"Euheueung...!! Ah-hang...?! Aheueut...!!!"
Right in front of her fiancé, Gahyeon was becoming a complete bitch who knew nothing but carnal lust.
Seeing An Hyeonwoo watching us with his swollen face made sex feel far more thrilling than usual.
'Was taking someone else's possession this enjoyable?'
No.
It was probably because he wasn't just anyone.
The bastard who insulted my deceased parents and tried to steal away my one and only childhood friend through despicable and cowardly means.
Because this was punitive sex against a bastard worse than trash, it tasted all the better, felt all the more exhilarating, and immersed me deeper into a sense of conquest.
Unlike me, whose curled smile showed no sign of coming down, tears of bitter regret welled up in An Hyeonwoo's eyes.
"Puhahahaha!! Hey! Hey! Are you crying?!"
Kkuguguguk!!!! Kkuguguguguguk!!!!!!
"Oho-ok...!!! My womb...!! My womb is getting crushed, Master-niiim...!!! My womb...!! My wooomb...!!!"
Ssupong?!
There was a feeling as if the tip of the cock slipped smoothly inside something.
"Huh?"
"Haaak.......?!???!?!??!?!"
Letting out a dying scream, Gahyeon trembled violently throughout her entire body.
It felt completely different from the tremblings seen so far.
Her two legs supporting her body were shaking as if they would give way at any moment.
Gahyeon muttered while staggering.
"W-womb....♥ Inside the womb....? Inside the womb.... the feeling isss...."
What?
Inside the womb? Did she say?
'Then could that feeling of sliding a bit deeper just now be...?'
Swallowing hard, I pulled my hips back.
Teo-eok. Teo-eo-eok.
"Heuu-ut..!!"
Caught on something, the cock couldn't come out.
I pulled back once again.
Teo-eop!!
"O-ong-ot...!!"
'C-could this be...'
It's the glans.
It was clearly the sensation of the glans.
The glans was so large that it had definitely gotten caught in the womb and couldn't pull out.
I could feel Gahyeon's steaming hot womb warmly wrapping around my broad glans.
Overcome with a surging desire for conquest, I tightly gripped Gahyeon's arms.
And while pulling her relentlessly, I moved my hips with even greater vigor.
"Heu-ap!! Euryat! Euryaryaryat!!!"
Peok!!!!!! Peo-eok!! Peok!! Peok!!! Peok!! Peok!!!!
"Oh, oh...., o-oho, ho-o-ot...?! Uo-ong-o-o-ot...!!! He-e-ek...!! He-e...! He, hehe, he-e-e-e...!!"

With the inner walls of her womb being pounded by the glans, Gahyeon began to let out bizarre moans unlike anything ever heard before.
Gahyeon's expression, briefly glimpsed from above, showed her eyes rolled back as if she had completely lost all reason.
"Kheu-eut...!! What kind of tightness is this..?!!"
"W-womb♥ My womb isss...♥ on Master-nim's cooock...♥♥♥"
As if knowing what its duty was, Gahyeon's womb eagerly clamped down on and squeezed the cock.
What was happening now was truly authentic womb sex, womb mating.
"Han Gahyeon's womb is so fucking delicious...!!"
Peok!! Peok!! Peok!! Peok!! Peok!! Peok!! Peok!! Peok!! Peok!!
"Hehe..♥ Heh..♥ Womb..♥ Womb feels so goood...♥ Becoming a female suffering womb defeat..♥ Hee♥ Hehe♥ Heheee-it...♥"
"Y-you lewd female bitch!! Tighten your womb!! Tighten it more!!!"
Kkwa-a-ak!! Kkwa-a-ak!!
Pu-uk!! Pu-uk!! Peok! Peok! Peok! Peok! Peok! Peok!
"Womb feels so gooood♥ Feeling female happiness with my womb...!!! I can never..!! never go baaaack...!!!!"
"Submit with your womb, you female bitch!! Cum while getting your womb relentlessly pounded! You lewd, vulgar bitch!!!"
"Yeees...! Yeeheheee-e-et..!! Womb-submitting mating! Thank you so much for loving this vulgar female womb...♥♥♥"
"I'm cumming!!! Take it all with your womb!! Get pregnant with my child! Cum while being fertilized with my seed right in front of your husband!!!"
"Cumming..♥ C-u-u-m...♥♥♥ I'm cumming..♥♥ Cumming while enduring womb-submitting mating from Master-nim in front of my loser husband...!!!!"
Swa-a-a-at! Ul-keok!!! U-ul-keo-eok!! Swa-a-a-a-a-a-a-a-a-at!!!!!!
"It's so hooot, it's so hooooot...♥♥ Master-nim's dedicated seed-receiving womb is getting so hot...♥♥♥"
Teol-sseok.
Exhausted, Gahyeon collapsed onto the bed.
Eyes rolled back.
A mouth that couldn't close.
A face covered in tears and drool.
It was an expression that could only be made by a female who had tasted the ultimate climax.
An Hyeonwoo could not tear his eyes away from that spectacle.
'Ah, aah, aaaaaah...'
He couldn't believe that Han Gahyeon, who had always been so cold to him, was a woman capable of making such an expression for another man.
Moreover, even from Min Seolha, with whom he had shared countless affairs, he had never seen such a completely broken expression.
'I, I... I.... N-no! I can too...!'
I can do it too.
He tried to comfort himself like that, but it was an obvious lie.
He already knew.
That he himself would never, for the rest of his life, be able to turn a woman into a female like that.
A sense of defeat, humiliation, intimidation, frustration, despair.
They were emotions he had never felt even once before.
The fact that the cause was on a purely biological level made it sting and ache all the more.
Yun Seonghyun, having thoroughly sprayed his seed inside the fiancée's belly, walked over and untied the ropes suspending his body.
Peok!!!
"Kkeu-eu-eup..."
And then, as if lifting luggage, he picked up the body with one hand and tossed it straight onto the cold floor of the veranda.
"You just stay here and eavesdrop like a rat."
Kwang!!!
After a short while, sounds could be heard.
"....!! Ahng...!! Master...!! Heu-eu...!!!"
It was the sound of Han Gahyeon's moans as she was ravished relentlessly by Yun Seonghyun.
A faint silhouette could be seen through the window.
It was not that of a simple couple, but the image of a female being devoured without resistance by an overwhelmingly superior male.
As time passed, the sounds grew even louder.
"U-u-ung...!! Ha-a-ang...!! Mashteer-niiim...!! Ah-a-ang...!!!"
From the silhouettes reflected, the positions could also be guessed.
Lying on the bed with weight pressed down from above, pressing against the wall while ravishing relentlessly from behind, roughly kneading Han Gahyeon's breasts as she worked her hips, and countless other forms were reflected.
Even as the sun set and the night deepened, they showed no sign of stopping.
Rather, Han Gahyeon acted even more flirtatious and coquettish, and the more she did, the more wet and resonant the pounding sounds became.
The sounds from Han Gahyeon only stopped around dawn, as the night sky began to lighten slightly before sunrise.
From the side, Yun Seonghyun's voice could be heard.
"Ah, right."
Deureureuk!
"I completely forgot you were here, dude. Sorry?"
"......."
Yun Seonghyun's face, after mating like crazy all day, looked refreshed rather than exhausted.
Humming a tune, Yun Seonghyun untied the bound hands and feet.
And then he picked him right up, carried him outside the house, and tossed him onto the street.
An Hyeonwoo, whose body and spirit were broken beyond repair, looked up at the gradually brightening sky with eyes filled with anger and sorrow alike.
