"I... I told you, I don't!"
"Who... who would ever like a pervert like him!?"
Kei Shirogane bit her lip and hung her head low. Her long silver hair was tied back, exposing her burning, pointed ears to the rising steam of the bathroom.
Before meeting him, even if it was just chatting online, Kei did have feelings for Rin Ito.
A teenage girl in her rebellious phase, combined with her cold yet tsundere personality, meant she had few close friends at school besides Moeha. At home, there were only her brother and father; she had to keep many things bottled up.
But it was different on the internet.
Behind a screen, it felt like wearing a mask, and wearing that mask allowed her to take her real-world mask off.
There were many things she couldn't say to people she knew, but she didn't care when it came to a stranger online.
Rin Ito would listen to her troubles and vent with her, which made her very fond of him. If things had continued normally, she might have actually fallen for the Rin Ito on the other side of the cable, met him offline, and started a relationship in the proper order.
But now... the order was completely chaotic.
It wasn't just the order; Kei's heart was in a mess as well. Although she had vowed to perform "desire management" in front of Rin, it was actually just her being stubborn and tsundere.
She could have turned back before she lost her virginity yesterday, but now she had no idea how to face Rin and Moeha. She could only bite the bullet and proceed with the plan to manage them.
There was no going back. Never again.
"Ehh... you don't like him? But your body isn't saying that~"
"Uu...!"
Moeha gently pressed on Kei's lower abdomen. She could clearly feel a warm flow that didn't belong to her own body surging out. Moeha didn't tease her further, simply offering a few more playful remarks before continuing to wash her hair.
The three of them spent over an hour in the bathroom, finally managing to wash the clotted "egg flowers" (semen) out of her hair. After the sweaty trio took a quick shower together, they returned to the room that was still thick with the scent of lust.
On the floor, the bed, and the windowsill—the traces of their love-making were everywhere.
By now, Moeha and Chika had changed into light indoor t-shirts. Their plump, steam-warmed thighs were white and translucent, and two distinct points poked through their thin shirts.
Kei had changed into a fresh uniform. Her damp silver hair clung to her flushed cheeks, radiating an aura of pure, erotic innocence.
Kei put on a cold, serious face as she looked at the three of them. Rin's gaze drifted between them... The atmosphere feels a bit tense?
Rin winked at Kei.
"Kei, you mentioned you wanted to perform 'desire management' on us, right? Can you explain the rules clearly?"
"Hmph... you guys..."
Kei wanted them to find a clean spot to sit, but she scanned the room and couldn't find a single one.
"We'll just sit here~" Moeha giggled and sat on Rin's left leg, then patted his right leg for Chika to sit on.
Rin wrapped his arms around the sisters, holding them close before looking up at Kei.
Hard. Kei's fists were getting hard.
He's actually embracing both of them right in front of me!
"Big Brother already said it once. From today on, I am managing your desires!" Kei paused. "Even if you're 'bottomless,' you can't be too indulgent. So... from now on, every time you want to do it with Big Brother, you have to tell me in advance!"
"I have to tell you every single time?" Rin raised his hand like a schoolboy asking a question.
"Th-that's right," Kei said, hardening her resolve. "Big Brother is my property now. You need my permission."
"Understood." Rin nodded with a stern face. "Without your permission, I can't move a single inch, right?"
Kei raised an eyebrow... Big Brother is taking this so seriously?
After testing that Rin's stamina was "bottomless," she had actually considered giving up on the desire management idea. Moeha and Chika were girls; a few extra rounds wouldn't hurt them.
Initially, Kei was worried about diseases, but if it was only Rin, that wasn't an issue.
She wasn't worried about them looking for other men either.
While she didn't know what it felt like with other men, she knew that after being with Big Brother, there was no going back.
Since Big Brother was so dedicated to controlling his lust, she had to help him!
"Exactly! Without my consent, you can't touch them."
"Did you two hear that? Every time requires Kei's approval. If she says no, I can't move. Don't even think about 'sneaking a snack'!"
After finishing his serious declaration, Rin tapped Moeha and Chika on their heads.
"Eh? Every time?" Chika lowered her head, biting her lip and twiddling her fingers. "Reporting every time is so... so embarrassing..."
Moeha glanced at Chika... Sis really doesn't get it at all.
"Sis, Kei is doing this for our health. If Kei isn't too shy or bothered by the trouble, how can we be? Right, Kei?"
"Th-that's right." Kei stiffened her neck and nodded.
Looking at Moeha's smile, Kei felt like there was a catch somewhere, but she couldn't put her finger on it... Something feels wrong!
"Do you understand? Sis can't sneak around. You have to report to Kei and get her permission every time before you can do it with Big Brother."
"Eh... well, ugh... I... I understand."
