In a private room at a karaoke bar, Miku and Yotsuba both appeared preoccupied, their minds clearly elsewhere.
"Hmm... Yotsuba, didn't that staff member from earlier seem really nice?"
"Huh?! R-really?!"
Startled by the sudden question, Yotsuba's shoulders flinched. The two sat side by side on the L-shaped sofa, their faces—beautiful beyond words, though undetectable to most—were turned toward each other.
"Yeah, I think they were really nice."
"...Well, I did think they were a little cool."
"Right? Their forehead creases are so cool."
"Ugh, really?"
Despite her dismissive response, Yotsuba was actually quite intrigued by the man. His gaze was lecherous and creepy, yet passionate, stirring something in her.
No, no, no... I already told Uesugi-san I loved him, even though I abandoned everyone else.
Yotsuba shook her head vigorously, trying to shake off her thoughts. She was a sinful woman who had gone to the lengths of hurting her sisters' feelings just to be reciprocated by Uesugi Futaro. She couldn't be allowed to be distracted by some random karaoke staff member she happened to see today.
And Miku's acting strange too. She's still supposed to like Uesugi-san...
Miku was the one who had developed feelings for Fuutarou first, aside from Yotsuba herself. So why was she suddenly interested in someone else? Yotsuba was bewildered, unable to grasp the reason.
She's right. Their feelings for each other were just planted by the Demon App a moment ago.
"Excuse me, here are your fried potatoes!"
The door clattered open. The staff member who had been the center of conversation earlier strode in without waiting for a response.
"Huh? I didn't order—"
Thump. Yotsuba's heart pounded violently. A surge of intense emotion welled up inside her, stopping her words. Just the sight of the man's face in her vision stirred a mix of wariness, disgust, and a fluttering sensation in her chest.
"Ugh...♡"
"He's really cool, isn't he...♡"
"Mmm...♡"
When Yotsuba looked over, she saw Miku gazing at the man with a dreamy expression. A blush suffused her cheeks, and a soft, almost vulnerable femininity graced her features. It was unmistakably the face of a woman smitten with a man.
Why...?! Why?! This doesn't make sense...! I was sure I liked Uesugi-san...!
Ignoring Yotsuba's confusion, the man stepped closer. She instinctively tensed, but he simply reached for the glass sitting at the edge of the table.
Oh no! That's my juice...!
Realizing he was about to drink from her glass, a strange mix of physiological disgust, shame, and arousal washed over her. But it lasted only a moment. The instant he took a sip, her heart began to race faster.
Indirect kiss...?!
Yotsuba had kissed Fuutarou before. Now, a surge of excitement, both opposite and yet even greater than that previous moment, welled up deep within her chest. The sensation spread rapidly throughout her body, coursing through every fiber of her being.
"Ugh... Fuuu...!"
What is this...?♡ My heart's racing...♡
Unable to withstand the loathable yet intoxicating stimulation, she let out a gasp. Even she could tell her cheeks were flushed crimson. A heat radiated from the core of her body, gathering in her lower abdomen. It felt like the anticipation before her period started, when she couldn't resist the urge to masturbate.
What's happening...?!
Then, in the next moment, the man grinned. Seeing that smile sent another shiver of pleasure through me.
He's watching me...! He's laughing at me!
Disgusting... But I'm happy.
I should run... But I want to smile back...
Go away... But come closer...
Help me, God... Thank you, God!
"Um, could I... Could I ask your name...?" A husky voice rang out. It was Miku's calm, low voice—identical to mine genetically—but now it carried an oddly coquettish tone, resonating with a seductive quality.
"My name is Kamina."
"Kamino-san...♡"
"Hey, hey, don't call me so sweetly or you'll make me blush!"
The man chuckled and settled comfortably into the corner of the L-shaped sofa, right between Miku and Yotsuba. His behavior was clearly not that of a store employee. Yet instead of being annoyed, I realized I was actually delighted.
Miku was the same. Her voice trembled as she sighed, "Ugh," a smile that was both troubled and delighted playing on her lips. Her slightly parted lips and gaze, which clung to him like vines, made it clear she was sexually attracted to the man.
What are we doing?! This is so wrong!
Reason sounded the alarm, but she couldn't suppress it completely. A strange sensation, as if her body was moving on its own, overwhelmed Yotsuba. She felt an irresistible pull toward the man before her, a conviction that obeying him would lead to endless pleasure.
"Come here, closer. It's fine if you stick right to my body. You girls are cute, so I'll give you a special treat," the man said, reaching out his hand.
The moment his fingertips touched her cheek, she shuddered violently, as if struck by lightning. A numbing sensation invaded the depths of her mind, wiping her thoughts clean.
