W-w-what on earth is going on?!
Wasn't her sister supposed to be showing that man proof of her virginity to force him to take responsibility? Why was Kaguya-san here too? And who were those two other girls next to Kaguya-san besides Ai Hayasaka? Could they also be here for some kind of perverted party?
Since when did her airheaded sister become such a depraved slut?! She's already pregnant, yet she's calling people over for an orgy!
Moeha's mind was spiraling into chaos, but her face maintained its usual cute and composed smile. She quickly came up with a plan.
"I just happened to be passing by," Moeha said, blinking innocently as a sly, mischievous smirk played on her lips. "But Kaguya-san... you're coming to a place like this with your friends? Don't worry, I'll keep your secret, but..."
Moeha sized up Kaguya. It was a bit of a shame that Kaguya-san had already been 'devoured' by a man, but it would be fun to tease her and see her get flustered... Hmm?
Just as Moeha thought her plan was working, she noticed something strange. Something was very wrong! Normally, if someone was caught going into a hotel for a tryst, they should be blushing and begging for secrecy. Why was Kaguya-san so... calm?
Kaguya didn't give her a single chance to say the classic line: "Kaguya-san, you wouldn't want people to find out you're having an orgy with my sister, would you?"
If it were just a regular boyfriend, it wouldn't be a big deal, but this was a party with several girls. For the student council president of Shuchi'in, this was a massive scandal. Was Kaguya-san really not worried about being exposed?
"Moeha, you've got it wrong," Kaguya said with a gentle smile. "I was called here by your sister, just like you. Since it's such a coincidence, why don't we go up together?"
As she spoke, Kaguya took Moeha's hand. Kaguya found it strange that Chika would notify her own sister. Coming here meant Chika must have told her about the pregnancy. But that should be something kept strictly secret from family.
Could it be... that he made a move on Moeha without me knowing?!
Hmph... like sister, like sister. They both have that seductive slut blood flowing in their veins!
Although Kaguya was cursing them in her head, her face remained fixed in a tender smile.
"Ah, right, I haven't introduced them yet. This is Kaede Hoshizuki and Rin Hoshizuki. They are also friends of your sister."
"Hello, big sisters~ I'm Moeha, Chika's younger sister~" Moeha greeted them with a radiant smile, pretending she knew absolutely nothing about the pregnancy. "But I wasn't actually called here. I really was just passing by, so I won't disturb you and my sister."
Even though Moeha said that, it was a tactical retreat. She desperately wanted to see the man who had claimed both Chika and Kaguya, but she hadn't been invited... If she just barged in, her secret of planting a tracker on her sister might be exposed!
But now... Kaguya's eyes were clearly inviting her to join. If she was 'invited' by Kaguya, then she had a perfect excuse.
In Moeha's heart, Kaguya was ranked number one on the list of people she 'wanted to eat.' Seeing Kaguya being taken like this... Moeha felt a bit sour, like a favorite childhood toy had been snatched away. She felt a mix of jealousy and envy.
What kind of man could win the favor of the Ice Queen Kaguya? And more importantly... she wanted to see. She wanted to see the shameful faces and expressions of both her sister and Kaguya-san.
"You're not disturbing us at all. Let's go up together," Kaguya replied, exactly as Moeha expected. Moeha immediately gripped Kaguya's hand, her face lit up with a bright, cheerful smile.
...
Soon, the five of them reached the door indicated by Chika's room number. Moeha lunged forward, beating everyone else to the punch by knocking on the door. A moment later, the door opened.
Despite her internal tension, Moeha's face remained a mask of sunny cheer. When she saw Rin Ito standing there, she froze for a split second before Rin looked past her at Kaede and Kaguya with a confused expression. Before the other two could speak, Moeha chirped:
"Big brother~ I'm Chika's sister, Moeha. You can just call me Moeha~" Moeha gave him a high-energy, sparkling smile. Her lively demeanor reminded Rin of Megumi Kannou. She was the type of girl who could take a selfie with a cock pressed against her face while maintaining a pure, radiant smile. Moeha's smile was full of innocence, but Rin knew that if you cut her open, she was one hundred percent 'Black' inside!
"I just bumped into Kaguya-san on the street, and she said my sister was up here, so I came along. Hey, hey... big brother, what are you guys planning to play?"
"We're... shhh." Rin put a finger to his lips, signaling for silence.
Rin wasn't surprised by Moeha's appearance. He hadn't noticed her eavesdropping at the cafe, but the 'System Daughter' had alerted him when Kaede and Kaguya met her downstairs. While he didn't remember all the specific plot points regarding Moeha, he had a strong impression of her 'Pink-on-the-outside, Black-on-the-inside' personality.
Seeing a 'Pink-Black' girl suddenly appear at a hotel, Rin could guess Chika had been followed. But well... since she was here, she might as well stay. Even though time was short, Rin had made some preparations. Heh heh heh... of course, he didn't put anything 'weird' in Moeha's water.
"Come in first, and keep your voice down."
The hotel room was a suite. As Moeha stepped through the foyer into the living room, she noticed some suspicious stains on the sofa, and the bedroom door was tightly shut.
Rin cleared his throat and lowered his voice. "Moeha, don't misunderstand. I'm actually Kaede's boyfriend."
"...?"
"It's like this. Your sister claims she's still a virgin, yet she's pregnant with my child. Her explanation is that she shook hands with Kaede, then went home and masturbated without washing her hands... and that's how she got pregnant. Pretty ridiculous, right?"
"Hmm..." Moeha nodded, listening intently. She had only heard the gist of the pregnancy at the cafe. She had assumed her sister had stolen his cum and injected it into herself.
"She wants me to take responsibility, but I can't just be a 'patsy,' and I'm a man with a girlfriend," Rin paused. "Getting pregnant from a handshake and masturbating has a probability that's basically zero, but it's not impossible. To prove to me that it was an accident and not an intentional seduction, and to prove to Kaede that she didn't 'NTR' her, your sister is going to prove her virginity to us right now."
"I'm not an irresponsible man. If your sister really did get pregnant with my child by accident... don't worry, I'll take responsibility for her!"
Moeha tilted her head, her small eyes filled with massive doubt. It was all a bit messy; she needed to sort through this information.
