In an inn in a remote area of the beautiful world of Ky'lar...

"Perfect! Now this woman looks just like she did when she entered."

... Desmos, who had stolen the body and life of the beautiful bounty hunter Yuriel, put on her clothes and armor, guiding himself by the memory of his new body to then leave exactly as the original Yuriel entered.

"Big sister!!"

After that, thanks to the memories of her body, he easily found the place where she and her sister Helen had camped.

"Are you okay?!"

When Helen saw Desmos in Yuriel's body, she approached her without hesitation, like a puppy.

(Wow, she is even more beautiful than this body remembered!)

But the reality was that although Desmos still retains Yuriel's memories and has adopted a female body, the moment Desmos saw Helen, he was captivated by her, standing there stunned, not knowing what to say.

"Sister... What's wrong with you...?"

At that moment, Desmos remained silent despite Helen's worried questions, rapidly evaluating her, observing her intense eyes red like rubies scattered in a garden of blooming poppies. Her skin soft and smooth like snow, with a pink tone. Her crimson lips, like vermilion lacquer. Her beautiful, long hair, like the purple mist of dawn, which fell softly around her waist and her features of impeccable beauty. Wearing a white priestly robe that enveloped her voluptuous figure of perfect proportions, granting her a seductive air.

(Just as expected of twin sisters!)

Desmos then marveled at how their facial and physical features were very similar, except for the color of her skin and eyes, besides some small details, such as Helen being more childlike than Yuriel, in addition to having an even softer feminine quality that awakens the desire to protect her in people.

"I've reached my limit!"

Due to that, Desmos, unable to contain himself any longer, let out a roar with Yuriel's mezzo-soprano voice, thus pushing Helen down and taking her crimson lips with his own...

"Hmmmm~! Ah~♡... What did you do...? Big sister...?! Big sister...?! Big sister...?!"

... Thus breaking the facade.

"Shut up! I can't control my lust anymore! Just stay quiet and let me fuck you!"

"Nooooo!"

Thus Desmos tore Helen's clothes, including her bra, exposing her large breasts.

"Just by looking at them through the clothes I felt like they were going to burst, but seeing it in person makes it seem even bigger!"

Marveling at the sight, Desmos estimated that her breast size was at least G.

"It hurts!! It hurts!! It hurts!! Stop!! Big sister, stop!!!"

In that way, no matter how much Helen cried or pleaded while Desmos fiercely bit her nipples, it only managed to fuel Desmos's sadistic desires.

"Ahahaha, I'm going to enjoy this!"

Then, immediately after, Desmos removed the armor from the lower body, pulling down the short pants in the process, while playing with his own clitoris, sucking Helen's snow-white breasts, savoring the body odor and sweat emanating from her.

"?!"

But at that instant, something strange happened when Desmos suddenly felt a deep sense of loss in his stomach, as if "something" had disappeared, and the hand that should have been caressing his clitoris felt as if it were grabbing "something".

"What the hell is this?!"

Finally realizing it after diverting his gaze towards his lower bridge, letting out the same cry of surprise as when he took Yuriel's body a few moments ago.

"How is this possible...?"

Stunned, Desmos saw how while raping Helen, the female genitals of the body that Desmos had taken from Yuriel had unknowingly converted into male genitals, even larger than the original penis of Desmos's body.

"Could it be that, just as my soul can read this body's memories, this body is gradually adopting a form that suits my soul?"

Thus, without fully understanding the situation, Desmos considered a hypothesis trying to calm down.

"Nooooo!"

But in contrast, Helen, who saw the "thing" growing from her twin Yuriel's body, screamed in horror.

"... Who are you?... You're not my sister, are you?!"

At that instant, Helen finally understood the reason for her sister's sudden change and how the person before her, whose face looked like hers, was not her sister.

"Who are you and what did you do with my sister?!"

Helen then asked Desmos, flaring her nostrils with an expression of complete anger.

"Yes, that's right. I'm definitely not your sister. Isn't it too late to realize that now?"

But even when Desmos was discovered, he remained unfazed, admitting it while keeping his composure, then directing his gaze toward the forest stretching beyond.

"Is it my turn, Boss?!"

And from there, after receiving the cue, Ubel appeared, aiming the black gem ring at Helen's back.

(Flash!!)

"?!"

"!!"

(PLAF!)

Whereupon suddenly, a beam of light from the jewel illuminated Helen's body from behind, causing Ubel's body to fall backward with a dull thud, leaving Helen with a stunned look on her face.

"A-Aaaah..."

Then, after that, something mysterious and dark spread through Helen's clear red eyes, and gradually took over her entire body.

"Hehe~ I really did it~ Big sister~!"

Thus, in a short time, the deepest part of Helen's soul was consumed by that unknown entity. And she, with the face of a newborn chick, while rapidly blinking, looked at her tiny hand with five well-defined fingers, and sketched a dull smile that was out of place on her elegant face, playfully uttering those words.

"Mmmmm~♡ Ah...ahh~♡!"

And then, moments later, frustrated and unable to wait any longer, "she" stretched her small white hands toward the indescribably large and beautiful breasts that had grown on her chest, emitting a sweet and cooing voice that could melt any living being in the world.

"Hey, how do you feel?"

Desmos, hearing those moans that reached his ears, causing his newly reborn penis to become hard and hot as he asked, barely suppressing the heat rising from the depths of his body.

"It's the best!"

Finally, in response, she deliberately pressed her new breasts together to create pronounced cleavage and replied with the most wonderful smile in the world.

"But... Big sister... What is that...?"

And immediately, Ubel confusedly pointed his finger at Desmos's crotch.

“Ah, this is it… it seems that only death is what will truly separate me from my partner! Ha, ha!”

"But don't you admire young and beautiful girls?"

"It's fine. I still have these large breasts, this cute butt, this soft skin, these beautiful eyes, and this silky hair, so, all in all, I win!"

"If that’s the case, would you like me to give you a blowjob as thanks for earlier?"

"Yes. It would be an honor for my partner to enjoy a fellatio from my dear little sister."

Desmos then stood with his arms crossed and pointed his newly formed male organ toward Ubel, who now inhabited Helen's body.

"Ahhh~♡ Ahh ahh~♡ Sister~!"

However, they discovered after that the soul of Ubel, who was weak-willed and stupid, had been completely absorbed by Helen's body.

With that, both continued performing lascivious acts throughout the entire day and night, sealing that macabre ritual with a lustful kiss of promise as the starting gun. The two murderers who had taken over the bodies of the twin princesses celebrated their new life with sexual relations, panting wildly like animals, and having sex outdoors in the mountains, trying various positions.

It was that day when a beautiful mezzo-soprano voice and a charming soprano voice sang an obscene chorus that echoed throughout the mountains.

And now, years later...

"Ahhh~♡ Ahh ahh~♡ Ahhhh~♡"

"Haaa~♡ Haaa~♡ Haaa~♡..."

A bed, made with countless women's breasts, shook violently from side to side while two very similar-looking girls were intertwined on the bed, their bodies moving up and down to the rhythm of their large breasts.

"Take this, take this, take this, slut!"

The first was a light-brown-skinned girl who looked like a woman, but between her legs, she had a penis larger than that of an average man.

(Squiwsh! Squiwsh!)

She continued thrusting her hips with all her strength on the bed, repeatedly penetrating with her penis the vagina of the snow-white-skinned girl, similar to her own, covered in thick purple hair.

"Ah, ahh, ahhh~♡ Big sister~♡ Big sister~♡ Ahhh~♡ Ahh~♡"

Ubel, for his part, kept moving his hips wildly with his arms covering the back of his head, exposing the abundant hair in his armpits.

In recent years, Ubel's spirit had become so accustomed to Helen's body that their memories had intertwined in such a way that she no longer knew who she was. However, "She" didn't care and felt completely happy and satisfied just having her "Big Sister" by her side. But at the same time, Helen's body had also been deeply influenced by Ubel's soul. For her body, which originally lacked hair, now sported a thick and rough patch of hair in the armpits, pubis, and buttocks.

A strong feminine scent emanated from her hairy armpits, and the odor acted like a drug, altering thoughts and stimulating sexual desire.

In fact, it was possible that Ubel was spreading Helen's feminine scent. For lately, the number of "guests" who had gotten lost in the mountains and were staying at the inn had increased considerably compared to before.

"Ahhh ♡... Damn it! It's all because of this pussy, I've lost my pussy... It's all because this pussy feels too good!... Compensate for it, compensate for it!... As compensation, make my cock feel good!... This, this hairy, black, and ugly pussy, but it feels too good!... Aaah ♡!"

The feminine scent emanating from Ubel's armpits penetrated Desmos's nostrils, clouding his thoughts and causing him to become even more absorbed in the sexual act, resulting in his movements becoming more violent.

"I'm so sorry~♡ Because of me, your beautiful and well-endowed vagina disappeared...ahhh~♡... But as compensation, pour your hot semen into my vagina~♡...ahhh~♡"

They were truly twin sisters who reached climax together.

"....."

Desmos then gnashed his teeth, his veins swelling like those of a wild beast; his terrifying face made it hard to believe he was the once noble princess Yuriel, who had always been so kind to her sister.

"Aaaaaaaaahhhhhh♡♡!!"

Ubel, for his part, had his ruby-like eyes rolled back, his eyebrows arched, his tongue stretched out, his nostrils flared, and snot and saliva shooting out of his nose; his face was so ugly it was hard to believe he was Princess Helen of the nobility.

Then Desmos releasing a white liquid that spurted from his black, large, thick, long, and strong penis, which shot out of his hairy vagina, and the bodily fluids, both male and female, that mixed, splashing the bed made with women's breasts and the utensils made from the bodies of other victims, filling that wicked room with an even more lascivious and fishy smell.

"Haaaah~♡ Haaa~♡ Haaa~♡ Haaa~♡ Haaa~♡... haaa~♡"

But while both lay in bed, enjoying the pleasure following their sexual encounter...

"Excuse me! We would like to stay the night!"

... It was then that a melodious voice came from outside, and upon hearing it, they knew that new prey had arrived.

"Welcome!"

So with a malicious smile drawn on their lips, they put on the underwear and feminine clothes they had already become accustomed to, sketching a kind smile to receive their "important client" at the front door.

Thus, Desmos, dressed in dirty work clothes, and Ubel, dressed in a patched robe, appeared before the travelers, holding hands and squeezing each other's large breasts.

"Well, well, you must be tired after your long journey. Welcome inside!"

Although both were of the same sex, their faces and figures were so attractive that the travelers froze as if they had seen something erotic, momentarily looking away...

"This reminds me of home... I feel nostalgic..."

... Everyone except one.

"We also have natural hot springs in our main shop. They are great for beauty. Come and try them!"

"Hot springs?! I want to try!!"

Thus, deceived and attracted by the beauty of the devil disguised in innocence, and oblivious to everything else, Mireya went on his way, falling into the trap of the twisted twins.

"This is a chance to get more concubines"

Who, in turn, fell into Echidna's trap.
