Several days had passed since Shiori was raped.

"Well then... I’m off, Chika."

"Okay. Have a good day, big sister."

Chika watched Shiori leave the house in a hurry. She had been smiling as she saw her sister off, but the moment Shiori disappeared through the closing door, Chika’s smile vanished, replaced by a worried expression.

"Big sister... I wonder what happened..."

What troubled Chika was the change in Shiori’s behavior over the past few days. At first glance, everything seemed normal, but there were small things—her occasionally looking gloomy, her becoming a little less enthusiastic about sex. It was clear that something had happened. Since Shiori would not tell her anything no matter how much she asked, Chika was left with a vague sense of unease and worry.

"Is there anything I can do...?"

Still feeling worried, Chika got ready and left the house to head to school.

"...Huh? What kind of car is this...?"

Shortly after leaving the house and starting to walk, a black van that had been speeding along came to a halt right in front of Chika. As she looked up, surprised by the suddenness of it, the van’s door slid open and several men got out.

"Hehe, sorry for the sudden intrusion."

"Oh... she’s beautiful up close too."

"Wow, those are some seriously huge boobs. Hehehe."

"This one’s a seriously gorgeous girl as well."

The men grinned lecherously, their eyes lingering over Chika’s face, her ample breasts, and her waist as they let out voices filled with desire.

"...W-what do you want? Who are you people...?"

Chika felt both disgusted and terrified by the men who had appeared without warning and were directing their unrestrained desires toward her body. She held her smartphone, which she had taken from her pocket so she could call the police at any moment, and prepared herself to flee.

"Us? We came because we have something to discuss with you... with Chika-chan."

"Could you come with us for a bit? Heh heh."

"Why? I have no intention of going with you. I’ll call the police."

Chika braced herself and replied defiantly, though she felt anxious and frightened that a stranger had called her by name. The men, however, did not seem flustered.

"Heh heh... If you do that, it’ll only cause trouble for Chika-chan."

"W-what does that mean...?"

Chika was puzzled by the confidence in the man’s voice. Seeing her look uneasy, the men grinned, reached into their pockets, and pulled out a photograph.

"This is what."

"Huh...!? B-big sister...! Wh-what is this...!?"

The person in the photograph was Shiori. The image showed her being held down by several men, stripped naked, and raped. Tears streamed down Shiori’s face as she was assaulted. Chika stared at the photo in shock, then turned her gaze to the men. The one holding the picture grinned.

"What would happen if this photo got spread around...?"

"Ah...!"

The words, delivered in a questioning tone, were more than enough to serve as a threat. Seeing that Chika had fallen silent and looked down, the men grinned. One of them approached her, put his arm around her shoulders, and pulled her into an embrace.

"Well, we’ll tell you the details later. For now, just follow us."

"Uh... uh... yes..."

"Oh, and make sure you let the school know you’ll be absent."

Chika had no way to resist their words, so she nodded slightly and was led by the men into the black van.

They soon arrived at a room owned by the men. Once Chika was led inside, she was immediately shown something.

"What... what did you do to my sister...!"

A dozen or so photographs were laid out on the table. All of them depicted Shiori being violated. When Chika saw the images of her sister being raped and defiled, she cried out in anger, but the men only laughed.

"What do you mean, ’what’? To put it bluntly, it’s rape. Rape." 𝙧𝙚𝙚𝔀𝒆𝓫𝓷𝙤𝓿𝒆𝙡.𝒄𝙤𝓶

"It was only a few days ago. Hehehe."

"Your sister was seriously awesome. Hehehe."

"Ah...! So that’s why, big sister...! A picture like this...!"

The men’s words made Chika understand why Shiori had been acting strangely. In a fit of rage, she grabbed the photos laid out on the table and tore them to shreds.

"Oh, even if you tear them up, the data is on our end, so it’s pointless."

"Since it’s stored on a server, destroying the physical prints does nothing."

"But even though it’s supposed to be okay no matter how much gets torn, we’d still be a little annoyed if our printed photos got ripped up. We might be tempted to scatter the photo data everywhere."

"Ah...! Oh, I’m sorry... Please, please stop that...!"

Tearing up the photos changed nothing. When Chika’s face instantly turned anxious at the men’s words, they grinned.

"Don’t worry. Depending on Chika’s attitude, we won’t do anything like spreading them around."

"...What should I do...?"

The words were spoken with a sly grin. Trembling, Chika asked the question, and the men pointed.

"It would be great if you could use that sexy body of yours to make us feel good."

"Ah, now that I’ve had a taste of Shiori’s beautiful body, I’d like to try Chika’s sexy body next."

"Heh heh... Use those big boobs, that ass, that sexy body to entertain us."

"If you resist... Shiori’s photos will be spread all over the place."

"Ah...!"

The end of his outstretched arm pointed at Chika’s body. Bombarded with words filled with lust, she realized that the men planned to enjoy not only her sister’s body but her own as well. Chika instinctively crossed her arms in front of her body to protect herself, but the hunger in the men’s gazes would not allow it.

"...Uh, uh..."

Sensing this, Chika slowly lowered her hands.

"Hehe, good girl, Chika-chan."

"Well then... what should we start with?"

"Let’s have a great time!"

"Uh, uh... uhhh..."

Seeing Chika’s submission, the men nodded in satisfaction, stood up, and began to approach her. Faced with men closing in, their desires seething, Chika was unable to escape and could only sit there helplessly.
