"Here are the sheets, towels, toothpaste, and toothbrush... Even though we agreed to let you stay here temporarily, you are NOT allowed to mess with our things, especially our towels!"
After agreeing to let Rin move in, the four sisters helped tidy up Ichika's messy room. They brought him fresh bedding and toiletries that they kept in reserve. Most of Ichika's personal daily items had already been moved out, and though posters of famous stars still lined the walls, the room looked much more inviting after a quick cleaning.
Once the sisters left the room, Rin sent a message to Kaede.
Rin: [I'm staying at Nino's apartment for a week.]
Kaede: [???]
Rin: [Their grades are terrible. I'm staying over to tutor them.]
Even though they had a silent understanding, a reason still had to be given... even a porn movie needs a plot at the beginning.
On the other end of the phone, Kaede's lip twitched. Tutoring them at Ichika's place wasn't enough, so you moved into their house to "tutor" them? Are you tutoring them, or are they tutoring you?
Still, Kaede couldn't help but admire Rin. To be allowed into their home, he must have successfully charmed all of them, though she didn't know the exact details. The camera system only activated when Rin had intimate contact with them; aside from the time they disguised themselves as Ichika, there hadn't been much "action." Kaede felt an itch of curiosity. Did Miku act as an inside agent and come up with a plan?
Kaede: [Why are you telling me? I've lent you to Ichika for now. You should be asking her.]
She was testing him. She didn't care about Nino and the others; to Kaede, the sisters were just tools to cultivate Ichika's cuckold fetish.
Rin: [She probably doesn't know.]
Kaede: [Keep it that way. We'll give her a surprise later.]
The System's task for Kaede was to find a fellow cuckold enthusiast. But where would she find someone with such a perverted hobby? If she couldn't find one, she'd build one!
The System was actually very easy to fool. Kaede just did her daily tasks and pretended to have a cuckold fetish, and the System believed her completely. She had talked to Ichika so much about "forgiving Suzu so the three of them could be together." As long as Ichika eventually "forgave" her sisters for sleeping with her boyfriend, the System would likely be tricked into completing the mission.
Hmph... a cuckold fetish?
The System couldn't even tell she was faking it; how could it tell if Ichika was faking or not? Once the sisters made it a "done deal," and Ichika found out... given how close the sisters were, Ichika would surely choose to wear the "green hat" and forgive them.
That was Kaede's plan. On the surface, she told Rin she wanted to be cuckolded, but Rin's "System Daughter" had already told him the truth. Rin was just playing along.
[Daddy didn't bring a change of clothes, right? Let Mommy deliver them!]
A message from the System Daughter popped up on Rin's phone.
[What's wrong with her?] Rin asked curiously.
[Hmph... Mommy is still stubbornly insisting she's just acting, and she said I'm easy to fool!]
Rin didn't know whether to laugh or cry. Mother and daughter were both incredibly petty. He had planned to just make do for the night and go home tomorrow, but since the System Daughter suggested it, he asked Kaede to come over.
Rin: [By the way, I didn't bring any clean clothes. Can you bring some over?]
If Kaede knew what Rin was thinking, she'd be fuming.
Meanwhile, Kaede felt her heart racing the moment she saw the message. Her boyfriend was staying over at another girl's house and asked her to deliver clothes. How is this different from him going to a hotel and asking her to bring condoms!?
Wait... he didn't use condoms with the other girls.
Vivid images from the "NTR" novels and manga she used to complete her System tasks flooded her mind. A strange sensation surged through her body, and her fingers trembled as she typed.
It wasn't her first time being in a situation like this. When Ami and Maki played with Rin in the internet cafe booth, Kaede was the one who went in afterward to clean up the mess. Back then, she felt helpless, but now... How pathetic have I become? I haven't even been touched and I'm already soaking wet just from the imagination!
Kaede: [Fine. Wait for me.]
Kaede shook her head to clear the lewd thoughts. She changed her panties, packed a small suitcase with some of Rin's clothes, and—as a finishing touch—grabbed a few condoms from his drawer and tossed them in.
A short while later, Rin got a call. He went downstairs to find Kaede waiting with a small suitcase.
"Two changes of clothes... should be enough, right?"
"Plenty, thanks."
Kaede's resentful expression made Rin want to laugh. He gently rubbed her head before leaning down to kiss her lips.
"Hmph... that's better. I'm leaving now." Kaede gave his shin a sharp kick. "You... had better... 'TUTOR'... them... WELL!"
Rin watched her leave and headed back up with the suitcase. The living room was empty; the girls were in their rooms. Rin didn't call for them. He opened the suitcase, grabbed his things, and went to the bathroom.
The bathroom was packed with bottles and jars. He didn't know what most of them were, so he just used the shampoo and body wash. From the scent, he guessed the body wash belonged to Yotsuba.
After his shower, dressed in a T-shirt and shorts as pajamas, Rin walked back to Ichika's room while drying his hair. However, he found a guest waiting for him. Though she was still in the white dress from earlier, she had removed the wig. He recognized her by her shoulder-length hair.
"Uh... Miku?"
Rin opened the door to see Miku sitting stiffly on the edge of the bed, her face bright red. She tried to act natural, but Rin noticed his suitcase had been rummaged through. Several square, foil-wrapped condoms were scattered on top of his clothes.
Kaede had definitely done that on purpose. He never used condoms with anyone but her. It was awkward for Miku to find them, but...
I didn't even see those when I took my clothes out. Miku must have dug through my suitcase while I was in the shower.
"The suitcase is a mess." Rin sat down next to Miku, a smirk playing on his lips. "Miku, what were you looking for in my luggage? Were you trying to steal my used underwear?"
"!!!"
