"Big Brother, choose me or choose her!"
Megumi looked at Rin Ito with anticipation, her small fists clenched.
Hinata, standing nearby, fixed her gaze on Rin Ito... He's Kaede's boyfriend, yet he's being so casual with Megumi.
Hm... I'm not cuckolding Kaede; I'm helping Kaede win her man back! I'm repaying her, not betraying her!
Hinata easily convinced herself and stared directly at Rin Ito, awaiting his answer.
"I..."
Rin Ito had just begun to speak when Saya interrupted him. Saya lightly bit her lower lip and cast her eyes down. After taking a deep breath, she bravely looked up and met Rin Ito's gaze.
"If... if you choose my sister, I... I can be with my sister too."
Saya's words excited no one more than Ami.
"Maki and I can join too!"
Ami excitedly walked to Megumi's side and looked at Rin Ito with anticipation. If Rin Ito had simply chosen Megumi, Ami wouldn't have had a reason to join in on the perverse activities. But now that Saya had made the offer, Ami had a perfect excuse!
"?????????"
Rin Ito was utterly bewildered. What is going on?
Rin Ito had only intended to call them over to explain things, since Kaede was his actual girlfriend, and they were all just acting.
Now... they seemed to be planning to make the fake relationship real?
Rin Ito could understand Megumi, who was desperately trying to save face in front of Ami and Maki.
But Saya and Hinata were incomprehensible to Rin Ito. Even if Hinata didn't want to tell Saya the truth, couldn't she just say they broke up? And even if she didn't break up... what was Saya doing offering to join her sister?
Rin Ito didn't understand, but he was deeply shaken. He could only rationalize it by reminding himself that this was the underground world .
However... his System Daughter should know exactly what happened. Kaede and Suzu should be home by now.
"Give me a few minutes to compose myself."
With that, Rin Ito ran upstairs to Mashiro and Nanami's room. The window of their room faced Kaede's room, so he could contact her if she was there.
Rin Ito: [Are you there, are you there, are you there???]
System: [I am, Dad. What's up?]
In less than a second, the System Daughter's voice echoed in Rin Ito's mind. Just as Rin Ito suspected, Kaede was undoubtedly waiting in her room for the Camera System to activate.
Rin Ito: [Can you tell me what happened with Hinata?]
System: [No problem~]
The System Daughter briefly recounted what had transpired between Hinata and Saya, but Rin Ito still struggled to understand why Hinata and Saya would make such a self-sacrificing offer. Even in the underground world, it shouldn't be this easy to get them to comply, right? He had only just met Hinata yesterday, and he literally just met Saya a moment ago. They must have an agenda.
System: [They will be Mom's comrades in the future, I can only tell you that much.]
Comrades?
Rin Ito paused. Comrades? What kind of comrades? Could they be comrades in being cuckolded?
Although Rin Ito didn't know much about Saya, Hinata seemed to have romantic feelings for her sister. If they were comrades in being cuckolded with Kaede, everything would make sense. Hinata has a fetish for being cuckolded, and the sister who deeply loves her would sacrifice herself to a man to fulfill her sister's fetish... Wait!
The System Daughter said They will be Kaede's Comrades in the Future.
They refers to both Hinata and Saya. Future means they aren't yet. Comrades if it means cuckoldry...
That would mean Hinata and Saya haven't awakened or have only a tendency toward the cuckoldry fetish, and they only made this self-sacrificing offer due to some other reason. Rin Ito's current task is to awaken the cuckoldry fetish in both Hinata and Saya.
In any case... even if I guess wrong, I won't lose anything.
After getting a rough idea of the situation, Rin Ito returned downstairs.
The two groups hadn't argued while Rin Ito was upstairs. Everyone was silently contemplative, seemingly nursing their own little schemes. Seeing Rin Ito descend, all eyes fell on him.
"Big Brother, have you decided? If you choose me, Ami and Maki can also join to serve Big Brother."
"My sister and I can too." Saya said, blushing and speaking firmly. After speaking, Saya remembered Kaede's hint: "So... choose Hinata. My sister and I have better figures than them!"
The girls all waited for Rin Ito's choice.
Faced with such a happy dilemma, Rin Ito's choice was, of course... to make no choice!
Only children choose; adults want them all!
"Ahem." Rin Ito cleared his throat. "You're making this very difficult for me to choose. How about... you have a service competition? Whichever side wins, I'll choose that side."
"Big Brother is so greedy," Megumi instantly saw through Rin Ito's thoughts. But... it doesn't matter! Attending a party is also something I can brag about. Most people at school only date and do it with their boyfriends, but she got to attend a party! If they didn't believe her, she could even bring them along to the next party.
Saya silently cursed Rin Ito for being so promiscuous... Why does Hinata like a person like this!? To the extent that she won't give up even when he openly cheats.
I don't understand, I truly don't understand.
But... since my sister likes him, I'll help her win him.
Personally sending the sister I love into his hands, personally giving him my purity... This way, I will definitely cut off this forbidden love.
"How will we compete?" Saya asked, her voice trembling.
"First... a figure competition," Rin Ito paused. "Don't worry, I don't have any specific preferences for body types; even if you're flat as a board, it's fine."
"You don't need to specifically say that!" Maki glared fiercely at Rin Ito. "And we are not flat as a board... Ami, why are you taking your clothes off so fast!?"
While Maki was complaining, the impatient Ami had already stripped out of her uniform. Ami's underwear was symbolic of innocence: pure white cotton lingerie. The innocent lingerie covered the girl's slightly undeveloped body, a burgeoning beauty waiting to be discovered.
"Eh... didn't you say we're having a figure competition? Since it's a competition, we have to take our clothes off! Maki, you should take yours off quickly too~" Ami mischievously placed her hands on Maki's shoulders, then let her fingers drop to the buttons of Maki's sailor uniform.
"Ami!!!!" Maki blushed. "I can do it myself!"
Maki glared fiercely at Rin Ito one last time, then stripped out of her uniform. As the pleated skirt slid down from her waist, Maki's underwear was revealed to Rin Ito's eyes.
Ami was covering her chest, staring at Rin Ito with a mix of shame and anger. "Don't stare at me!"
Although Rin Ito had seen Maki in the adorable catgirl outfit at Sagiri's house last time, this was the first time he'd seen her lingerie. Although Maki's underwear was also white cotton, just like Ami's, unlike Ami's pure white, Maki's panties were printed with a cute little bear pattern.
Seeing Rin Ito's gaze fall on the little bears, Maki quickly covered herself with her hands.
"No way!? Can't I wear bear panties?"
"Of course you can," Rin Ito held back a laugh. "Not only can you, but they're very cute. I just thought that kind of bear panties would be something Ami would wear, and that you, Maki, would wear something more mature."
"Hmph!!! What I wear is none of your business! Megumi! We've both stripped; why haven't you yet!"
We, Ami and I, came to help Megumi win her man, but we're stripped and she hasn't taken anything off yet.
"Ami! Let's help Megumi strip!"
"Wait... wait a minute!!!"
Ami and Maki, one on the left and one on the right, simultaneously grabbed Megumi. They unbuttoned her uniform and pleated skirt and pulled off Megumi's uniform instantly. Unlike their pure white underwear, Megumi's panties were a blue and white striped 'shima-pan' (blue and white bowl).
But... just stripping off the uniform wasn't enough!
"Kyaaaa!!!!" Megumi screamed. Maki and Ami had already hooked their fingers into the edge of her panties.
"S-Stop! Not so fast!"
"Hmph... In a competition, you have to seize the initiative!"
"That's right~"
Ami and Maki both curled their lips into mischievous smiles. The next second, the blue and white panties fell to her ankles, and the tightly closed slit, free of any pubic hair, was exposed to the air.
"Eeeek!!!!!"
