"???"
A cuckold fetish!?
"Mmm... it seems quite logical to me that she'd develop such a taste."
Rin Ito paused for a moment.
"Hatsune's childhood forced her to cope by fantasizing about being a tragic heroine. Combined with the fact that she knows her love for you is a taboo, she had no choice but to retreat into fantasy—dreaming of you being stolen by me while she hides alone under the bed or in a closet."
"...."
Sakiko didn't know what face to make, but his logic was undeniably sound.
"To put it simply, it's the result of long-term sexual and emotional repression."
Sakiko massaged her temples... Mutsumi's issues weren't even resolved, and now Hatsune's baggage was piling on. Her only consolation was that Hatsune's mental state didn't seem as fractured as Mutsumi's.
She didn't actually care about Hatsune's "Uika" identity; she was far more worried about the girl's sanity.
"Should we... let her find a release?"
Sakiko felt helpless.
Mutsumi was a product of repression; now Hatsune was too... If they keep bottling things up, are they all going to break?
"Giving her your underwear was a shallow form of release. Speaking of which..." Rin shot Sakiko a sideways glance. "Since we're helping Mutsumi vent her stress, why not let Hatsune join in?"
"Eh?" Sakiko swallowed, looking at Rin with wide, nervous eyes. "Do you mean... like before? With her?"
"No, no. Not like that." Rin waved her off, and Sakiko let out a breath of relief.
Knowing Hatsune held "strange" feelings for her didn't make Sakiko judgmental... after all, it was her grandfather's fault, not the girl's. She was happy to remain friends as before.
But as for a party...
Sakiko could handle Karen's "no-strings-attached" parties—even the messy parts where they licked each other—because there was no romance involved. It was just a release of desire and stress.
She could handle a party with Mutsumi. But one with Hatsune...? If she hadn't known the truth, maybe. But now that Rin had exposed her feelings, Sakiko found it hard to accept.
"To put it simply: you'll be on the outside letting Mutsumi and I punish you to let her vent, while Hatsune will be in the closet taking care of herself... Mental stress is hard to clear, but we can at least let her release the physical pressure."
"Since we're throwing a party anyway, we might as well do it all at once... what do you think?"
"Mmm..." Sakiko hesitated. Being watched was one thing, but she was still a virgin!
Being "taken" by him not just in front of Mutsumi, but in front of Hatsune too... the thought was mortifying!
However...
Maybe I can make her give up on me?
Hatsune has a cuckold fetish, but if she sees me being taken by him, making such wanton, ugly faces, maybe she'll be disillusioned?
Maybe I can cure her of this 'NTR' interest so we can just be normal friends.
"Fine." Sakiko nodded, giving a reluctant consent. "But..."
Sakiko's eyes darted around.
"Before that, I... I probably need more training. Like... endurance training..."
"Endurance training? I thought you were in a rush to write music?" Rin teased with a wicked grin.
"The music can wait. Mutsumi's condition cannot... so training is more important right now," Sakiko lied poorly.
"Sigh... I was going to leave, but since you're begging for a lesson, I'll help you out~"
Rin stood up and went into the bedroom to grab some handcuffs and other gear. Despite her nervousness, Sakiko submissively shed her uniform.
Her pale blue lace-trimmed lingerie hugged her petite frame, making her look pure and innocent. Beneath that lace, however, every inch of her body—save for the final gate—had already been "developed."
Rin returned from the room and stopped her as she reached for her bra.
"Keep the lingerie on." As he spoke, Rin cuffed Sakiko's hands behind her back and locked her ankles into a spreader bar, forcing her legs wide.
Handcuffed and restrained while still in her underwear... Is he going to use scissors to cut them off?
As Sakiko wondered, Rin gave her rear a light pat. Without needing a word, Sakiko instinctively leaned over the sofa and stuck her ass in the air.
He slid her panties down just enough to expose her twitching petite rear. Rin didn't toy with her much; he simply applied some lubricant and slid a toy roughly the size of a cat's tail inside her.
After pulling her panties back up to secure it, Rin tucked several oval vibrating toys into her underwear—some against her crotch, some against her chest. What was once the final defense for a girl's modesty was now a cage of torment.
With the toys tucked firmly against her skin, Rin spoke.
BZZZZZZZT.
Rin clicked the remote to the maximum setting.
"GUH... WAIT! STOP! NOT... NOT THAT HIGH!!!"
The violent vibrations made Sakiko's entire body go rigid, but the machine had no mercy. Since she asked for endurance training, he was going to give it to her.
Rin ignored her pleas, buckled a ball-gag into her mouth, and carried her into the bedroom.
"Stay like that until the batteries die. Good luck."
With that, Rin closed the door, leaving Sakiko alone in the room to be ravaged by the machines... or rather, to complete her "endurance training."
As for Rin...
He washed his hands and sat on the sofa, creating a group chat for Mutsumi, Soyo, Taki, and Tomori. Tomori and Taki still had no idea that Rin had already eaten Mutsumi and Soyo.
Corrupted by Ryo and Bocchi, Tomori simply thought a party was a normal band activity to repair the cracks in their friendship.
They couldn't be a "lifetime band" as they were, but they could be "lifetime friends." After a party and a reconciliation, maybe they could even be friends for three lifetimes.
Taki wanted to argue, but seeing Tomori so enthusiastic, she could only sigh and follow along.
Rin Ito: [You mentioned wanting a party. Are you free tomorrow night?]
Soyo: [I'm free whenever~]
Soyo's mother was always working; no one was home to watch her.
Mutsumi: [I will tell my parents I am staying at Sakiko's.]
Following Mutsumi's lead, Taki and Tomori planned to tell their parents they were staying at each other's houses. Their parents knew about the band.
A "Band Training Camp" was a perfectly valid excuse.
Rin Ito: [Go out and have dinner together after school tomorrow, then come over together.]
Rin Ito: [By the way, don't tell Sakiko. I want to give her a surprise.]
Rin Ito: [I'm sure she'll be thrilled~]
