The sisters confessed their secret feelings for each other and, despite their forbidden relationship as siblings, were united.

From that day forward, the two began living together and spent their days happily.

But the two sisters were beautiful, and there were men who harbored wicked desires.

Under their influence, the sisters had their purity taken away, their happiness destroyed, and they were dragged into a world of dark desires.

It was early morning, just as the sun began to rise outside the window.

"Mmm...♡ Mmm...♡"

"Mmm, mmm...♡ Mmm, mmm...♡"

Shiori and Chika, who were sleeping in the same bed, kissed each other as soon as they woke up.

"Mmm...♡ Good morning, Chika...♡"

"Mmm...♡ Good morning, big sister...♡"

After a long, passionate kiss, they pulled away from each other’s lips. The two exchanged words while gazing at each other with intense eyes.

After that, they got out of bed and began getting ready for the morning. They ate breakfast, tidied themselves up, and checked their belongings.

"I think I’ll be home late today, so please prepare dinner, Chika."

"Okay, I understand. Leave it to me, big sister."

After telling Chika this, Shiori left the house and headed to university.

Time passed, and evening came. Shiori was walking home through a residential area.

"Phew... I’m glad it ended sooner than I expected. Let’s go home."

Shiori hurried home to where her beloved sister was. There was no sign of people around; it was quiet.

...No—a black van was slowly approaching from behind.

"...? ..."

Noticing the black van, Shiori quietly moved to the side of the road so as not to get in its way. However, the black van slowly approached her... and at the very moment it drew alongside her—

"...!? Kya—ngh!?"

"Hey...!"

"Got her..."

Suddenly, the van door opened, and Shiori was forcibly dragged inside by the men who emerged. The black van that had taken Shiori inside closed its door and sped off, disappearing from the scene in an instant.

"Hehehe..."

"We caught you!"

"She’s beautiful..."

Inside the van driving down the road, the windows were covered with black sheets, making it impossible to see outside. Shiori was being held down to the floor by several men, who had grabbed her arms and legs. The men’s eyes, as they gazed at Shiori, were filled with lust, and it was clear they harbored malicious intentions toward her.

"W-what...? What do you want?! You people...!"

Although Shiori appeared somewhat frightened, she quickly straightened her expression and raised her voice at the men. Looking down at her, the men slowly reached out their hands, grinning lecherously.

"Heh heh..."

"Heh, heh heh..."

"Huh...!? Wait—stop, stop it...!? What are you trying to do...!"

The men’s hands reached for Shiori’s clothes and slowly began to pull them up. Slowly, first, they made her expose her belly completely. Shiori screamed in shame and struggled to shake off the men’s hands, but a woman’s strength was no match for theirs, and she didn’t budge.

"Hey... don’t struggle too much."

"Huh...!? Wh-what..."

However, they seemed concerned about her continuing to act out. One of the men held a knife to Shiori’s face. When Shiori saw the gleaming blade, she looked devastated, and all the strength drained from her body.

"Heh heh... That’s better."

"Now, let’s get these clothes off quickly."

"Come on!"

"Uh, ah... ah, yes—yes, ah..."

Seeing that Shiori had stopped resisting, the man grunted in satisfaction, put away the knife, and began to undress her again.

"Wow... this is amazing."

"I always thought she had a good figure, but I didn’t realize it was this good."

"Incredible."

"Uh, uh..."

In no time at all, Shiori’s clothes and underwear were stripped off by the men, leaving her completely naked. Faced with her beautiful, exposed naked body, the men gazed at her with excited expressions. In the face of their lustful eyes, Shiori was filled with nothing but shame, disgust, and fear.

"Don’t make such a disgusted face—it ruins your pretty face, Shiori-chan."

"Huh...? H-how did you know my name...?!"

Upon hearing this, one man exclaimed. But when a stranger suddenly called out her name, Shiori’s face contorted with even more fear and surprise. Seeing that reaction, the men began to grin and speak one after another.

"Heh heh... Shiori-chan. We’ve been interested in you for a while now."

"You’re such a stunning beauty, and on top of that, you have an amazing figure... I thought you were an irresistible woman."

"I’ve always wanted to do it to you... to rape you... and I’ve had my eye on you for a long, long time."

"I couldn’t hold back any longer. So I decided to make a move. Hehehe."

"W-what..."

Shiori could only tremble at the men’s selfish words, filled with their desires. Looking down at her, the men grinned and picked up the clothes they had stripped off her.

"Hehe... It smells nice. The clothes Shiori was wearing."

"The smell of the clothes a beautiful woman wore all day... it’s irresistible."

"I should take a good sniff while I have the chance."

"W-what...! Stop it...! Don’t sniff them, please...!"

The men held Shiori’s clothes to their noses and inhaled deeply. As they sniffed the garments just taken off her body, she cried out in shame and struggled again, but the men held her down.

"Hey, don’t struggle!"

"I’m not going to stop... This is the only time I can smell the scent of freshly removed clothes."

"Being shy only excites us more. Hehehe."

"Uh... uhhhh..."

Shiori’s face simply turned redder at the men’s words. Looking down at her, the men continued to sniff her clothes, grinning, but eventually, seemingly satisfied, they tossed the garments to the back of the van and turned their gaze back to Shiori’s beautifully sculpted body.

"Well then... let’s begin. I’m going to enjoy Shiori’s beautiful and sexy body."

"Just looking at it is making my dick hard. Hehehe."

"I’m going to do it to my heart’s content, thoroughly and slowly. Be prepared. Hehehe."

"Ah... Ugh... Stop, stop...! No, no...!"

"Whoa...! You really do cause a lot of trouble!"

"Calm down a little... Shiori-chan!"

The men raised their voices in accordance with their desires. Faced with such lust, filled with disgust and humiliation, Shiori tried to thrash about again but was restrained.

"No...! No, ah...! I won’t let you do whatever you want with me...! For Chika’s sake too...! Absolutely not...!"

Nevertheless, Shiori thought of her beloved younger sister. She thrashed about as if to say, "I won’t let these men defile my body like this," and uttered her sister’s name.

"Chika...? ...Ah, you mean Shiori’s beloved little sister."

"That girl is great too. She has a pretty face similar to Shiori’s... and those ridiculously huge breasts are especially nice."

"You two recently started living together, right? It’s great to hear you’re getting along so well."

"If her name slipped out of your mouth like that, you must really care about her."

"Huh...?!"

The men reacted strongly to the name "Chika" that Shiori uttered. Shiori was surprised that they knew about Chika’s existence so well, and she instinctively stopped struggling, while the men began to talk, smirking.

"Your beloved little sister is waiting for you, right? You want to go home as soon as possible, don’t you? Then... you understand, don’t you?"

"I’m not saying you have to be enthusiastic about serving me... I just want you to let me use this sexy body of yours."

"If you can satisfy us quickly, you can go back to your sister right away."

"On the contrary, if you keep resisting... then I’ll have no choice but to do the same thing to your sister. Hehehe."

"Ah...! Uh, uhh... uhh..."

With her beloved younger sister used as blackmail, Shiori no longer had the strength to resist. She relaxed her body and simply hung her head.

Seeing Shiori’s state—having lost all will to resist—the men nodded in satisfaction, their eyes filled with desire, and reached out their hands toward her body.
