Miku impersonating Ichika alone almost pushed Ichika toward a mental collapse, but seeing all four of them dressed as Ichika... she actually wanted to laugh. When a person reaches the peak of absurdity, laughter is the only response left.
Four of them? What the hell?
Kaede breathed a sigh of relief seeing Ichika's reaction. At least she wouldn't be going on a murderous rampage. Kaede turned her attention back to the scene outside the closet.
Outside, the four girls were gesturing frantically in front of the blindfolded Rin. Finally, Nino, Yotsuba, and Itsuki balled their hands into fists... Rock, Paper, Scissors!
Watching them settle their turn order with a game of chance, Ichika didn't know whether to cry or laugh. She wondered how they had all fallen for him. Miku she could understand, but Nino? In Ichika's memory, Nino hated him because she felt he was tearing their family apart.
Before Ichika could figure it out, the game ended. Yotsuba was the winner, followed by Miku, then Nino.
Yotsuba grinned, flashed a V-sign to her sisters, and stepped in front of Rin, adopting Ichika's signature tone.
"Sorry to keep you waiting~ Here comes the shock and surprise~"
"Surprise? What kind of surprise?"
"It's a rope~" Yotsuba giggled as she undid his shirt buttons and belt, stripping him bare before tying his hands behind his back. "Just leave everything to us now~"
With that, Yotsuba pressed her lips against Rin's. Nino and the others pulled out their phones and started their stopwatches. Unlike Miku earlier, Yotsuba didn't stop at a simple kiss. Her smooth lips and tongue traced a path along Rin's jaw and neck, sucking and licking, eventually nipping lightly at his chest.
"Hehe~ Getting excited?" Yotsuba smirked, her hand sliding down his thigh to grasp his heavy sac, kneading it mischievously. At the same time, her tongue trailed down from his chest, over his abdomen, and finally reached his groin.
"Ahn~"
In the next moment, Rin was taken into Yotsuba's warm, wet mouth. Her small, agile tongue explored every inch, leaving no sensitive spot untouched.
"Hiss..."
Rin tilted his head back, inhaling sharply. Seeing how much Rin was enjoying it, Nino frowned. Looking displeased, she grabbed the back of Yotsuba's collar and pulled her away.
"Ichika? Why did you stop?" Rin asked.
"I accidentally took it a bit too deep, just taking a breather," Nino replied using Ichika's voice. She glanced at Itsuki and pointed at Rin's crotch.
Itsuki, wearing her contact lenses, instinctively reached to adjust her non-existent glasses before kneeling in front of Rin. Her slender fingers tucked a stray lock of hair behind her ear. She opened her mouth and swallowed the thick rod that Yotsuba had left glistening with saliva. Beside her, Nino couldn't stay idle; she reached out to gently massage Rin's balls.
After a short while, Itsuki stood up, and Nino took over seamlessly. After Nino came Miku. The four of them rotated according to the order of their game, each taking their turn to service Rin's cock.
It was like a game of Russian Roulette! Each girl had one minute to perform oral sex, betting on whose turn it would be when Rin finally erupted.
In the closet, Ichika watched her sisters, unsure of what expression to make. Is that thing really that delicious? They look like they're savoring a gourmet meal.
Ichika had only ever gone as far as kissing Rin. Despite her "actor" persona, she had never used her mouth to serve a man like this. In reality, not everyone was like Mashiro, who genuinely enjoyed the taste. For these girls, it was mostly about the psychological thrill.
They were putting on a show of "enjoyment" because of Miku's plan. Miku had convinced them that the real Ichika was going to "catch" them, so they had to show her just how much they loved being with Rin.
"Ngh... Ichika, I'm close."
In the closet, Ichika almost reflexively answered when she heard him call her name. But a second later, she realized he wasn't calling her; he was calling Miku. With a complex expression, Ichika bit her lower lip and stared intently at the scene.
Currently, it was Nino's turn. Hearing Rin's voice, she buried her head deep, fighting back the gag reflex as she forced herself to swallow the length of him. However, the volume was too much for Nino to handle all at once. White fluid leaked from the corners of her lips before she could swallow it all. After a moment, she lifted her face and wiped her mouth with the back of her hand.
"So much... is big sister's mouth really that comfortable?" Nino asked, maintaining the "confident Ichika" persona. In reality, she felt like she was drowning, but Rin was not stingy with his praise for her effort.
"Of course. Your tongue and mouth are the best, Ichika."
In the closet, Kaede mentally spat. He says that to everyone!
"Flattery won't get you anywhere, hmph... I know you've been craving my sisters. Tell me, who do you want me to dress up as next?"
"Ahem... I'm just trying to test your acting skills, I definitely don't have designs on your sisters' bodies!" Rin sat up straight, sounding solemn, but he lacked any shred of credibility.
"Fine then... let's go with Itsuki."
"Wait a moment, I'll go out and 'put on some makeup'."
With that, the four sisters ran into the living room. Shortly after, Itsuki—having removed her "Ichika" disguise—returned to the bedroom and took off Rin's blindfold.
"How is it? Do I look the part? I... I'm 'Itsuki', okay?"
"Exactly the same."
Exactly the same, my ass!!! Ichika screamed internally. Makeup? She just washed her face! She IS Itsuki!
Itsuki, now wearing her glasses, winked at Rin and spoke shyly, "Professor Rin... today... today, please teach me Health and Physical Education!!!!"
Before she could finish, Rin scooped her up and threw her onto the bed. As he buried his face in her neck, kissing and sniffing her scent, his restless hand slid under her skirt and between her thighs. To give Ichika a better view, Rin intentionally adjusted their position, hiking up Itsuki's skirt so the "voyeur" could clearly see the glistening, wet folds of her pussy.
However, despite Rin's positioning, Ichika... wasn't even looking. She didn't actually have a cuckold fetish; she had only looked for a few seconds at the start.
This was within Kaede's expectations. Ichika's "fetish" was just talk, much like how Kaede herself faked it for the System. To cultivate a true fetish in Ichika, she couldn't just watch her lover with her sisters. That would only lead to Ichika forgiving them. Ichika needed to feel the physical pleasure of the act!
Just like the System's tasks, which forced Kaede to masturbate while watching... Kaede realized the System wanted the body to associate "being cuckolded" with "sexual pleasure."
Even if I'm faking it to fool the System, there must be logic behind it. When I see him with other girls, I do get wet... like right now.
Kaede's panties were already soaked. If Ichika wasn't right in front of her, she would definitely be fingering herself to a climax. But that's just a bodily reflex! It doesn't mean I actually have the fetish!
Kaede figured the System's method might work on Ichika. She didn't plan on using "Sensory Link" or other cheats; if the System thought she was cheating, it might not count toward the quest.
Kaede leaned in and whispered into Ichika's ear, "Don't you have a cuckold fetish? Why are you just staring? Don't be shy in front of me~"
"!!!!"
Kaede's words snapped Ichika back to reality. Right, she was supposed to have a fetish. If she wasn't soaking wet when Miku eventually found her, her secret would be out. She needed to at least have a few orgasms and leave some wet spots in the closet.
Ichika saw the mischievous glint in Kaede's eyes. If I just start playing with myself, she'll mock me forever... if I'm going to lose face, I'm taking her with me!
Surprise attack!
Ichika shoved her hand between Kaede's thighs. Touching the drenched fabric, Ichika froze. I was the one being teased earlier, not her... why is she so wet?
A smirk of pure delight crossed Ichika's face. She definitely has a cuckold fetish!
Ichika was still a virgin, but she knew Kaede wasn't. With a wicked smile, she easily slid three fingers inside Kaede's tight, wet cunt while pinning her thumb against the sensitive clitoris.
"Ngh!!!!"
Kaede tried to stop her, but the closet was too cramped for major movement. Furthermore, her "zakota" (weakling) body, enfeebled by System punishments, turned to jelly under Ichika's assault.
While Ichika ruthlessly fingered Kaede with one hand, she used her other hand to stimulate her own crotch. Kaede covered her own mouth to stifle her moans, while Ichika bit her lip to endure the pleasure.
Although Kaede was being toyed with, she had one advantage: both her hands were free. The closet door had been modified by Karen with an internal handle. Seeing the triumph on Ichika's face, Kaede smirked. Before the girl could realize her danger, Kaede braced herself against the internal handle and kicked the door.
A feeling of weightlessness hit Ichika. In the next second, she found herself sprawled on the bedroom floor, the cool air of the AC hitting her exposed, wet groin.
"!!!"
Cold sweat drenched her back. I... I fell out of the closet?
Before her brain could process the disaster, Itsuki's scream rang out.
"Ichika!? Wh-Why are you here!?"
Itsuki stared in horror at the sister who had just tumbled out of the closet. She was genuinely terrified. Miku had said Ichika would "catch" them, but she never mentioned Ichika would be hiding in the closet the whole time!
