"Wake up, wake up. Time for school."
"Mmm, five more minutes... EEEK!!!!"
Rin's voice jolted Nino and Miku awake. They were tangled together in Rin's bed. Though they hadn't stayed up all night, they hadn't slept well either. Being physically linked made finding a comfortable position nearly impossible.
Rin's method of waking them? Flicking their swollen nipples.
"Ah!!!"
"Uu!!!"
They woke up to see Rin's mocking grin. "So? Have you made up?"
"Pervert... undo this right now!"
"Yeah, undo it... Nino's breath stinks, she needs to brush her teeth."
"Ha? Who stinks!? You were drooling in your sleep and got it all over my face!"
Rin laughed. They were bickering, but the bond was clearly there. "Looks like you're getting along great."
He reached out and unclipped the clamps from their nipples. Because they had been on all night, the tips were slightly discolored and indented.
"It's your fault. What if the marks don't go away...?"
"Just massage them." Rin reached out with both hands, using his rough thumbs to rub their nipples. Within moments, the marks faded, and the blood flow returned. He replaced the clamps with their original crystal charms and handed them their uniforms and underwear.
"By the way, Kaede made breakfast. She wants you two to come over."
"Kaede? She made us breakfast?" Nino frowned. Even Miku looked suspicious. "Did she put something in it?"
Over the weekend, they had barely spoken to Kaede. Now, the main rival was inviting them over for a meal?
"Relax, Kaede isn't that petty." She wouldn't bother with poison when she could just use her system to sync their senses and make them feel every sensation of him fucking her. "She specifically told me not to go. She probably wants a girl-to-girl talk."
"Don't move... if the eyeliner smudges, we have to start over and she'll think we're afraid of her!"
Nino was helping Miku with her makeup. Even though they were naturally beautiful, facing a rival required full war paint. They were back on the same team. Once they were ready, they headed next door.
Kaede had barred Rin, Nanami, and Mashiro from the room, but she had prepared three portions of rice, miso soup, and grilled fish.
Rin sat in his own kitchen, but his mind was elsewhere.
[Daddy, they've sat down at the table... Hee-hee, the tension is delicious.]
Kaede didn't realize she had a little traitor in her head. The System Daughter was livestreaming the whole thing to Rin.
[Ooh, Auntie Nino is being very aggressive! She sat down with a 'mean girl' aura and started eating. Auntie Miku looks like she's getting ready to break up a fight.]
Nino's voice came through Rin's earpiece, transmitted via Kaede's phone microphone.
"The taste is just okay. I'll cook for you next time... Why did you call us here? You heard us last night, didn't you?" Nino's voice was sharp. "You can't win against the five of us. We can handle any perverted play he throws at us."
"That's right," Miku added. "Whatever you can do, the five of us can do better."
[Auntie Nino attacks! How will Mommy react...? Mommy has no reaction! Mommy is perfectly calm!]
"You can do it better? How funny," Kaede said calmly. "How are you going to satisfy Ichika's specific kink?"
"I..."
[Mommy hit the bullseye! Auntie Nino doesn't know what to say.]
Nino was speechless. She hadn't expected Kaede to know about Ichika's cuckold fetish. Damn it, Ichika! No matter how close you are to her, you shouldn't tell her that!
[Mommy is going for the kill!]
"The bond between you five is too strong," Kaede continued. "Whatever you do is just 'playing.' Ichika knows you won't actually steal him. It might be fun at first, but do you think that 'playing house' will satisfy her forever?"
"Whether Ichika is satisfied is none of your business!" Nino snapped.
[The battle is decided. Mommy came prepared and ambushed Auntie Nino.]
"It's true, it's not my business. But..." Kaede glanced at Rin (the girl) beside her, who picked up the cue. "If she isn't satisfied, the cracks in your relationship will grow."
Kaede nodded in satisfaction. "Now you know why Ichika is so close to us. He's my boyfriend; I'm just 'lending' him to her for now. I can take him back whenever I want. I can truly snatch him away from her. Only we can truly satisfy her kink by making it 'real'."
"..."
"Maybe I won't just take him. Maybe I'll take Ichika away from you four too." Kaede's smirk was wide now. "I'm not saying you have to leave him. I just want you to know your place."
Kaede stood up and walked over to Nino, reaching out to squeeze her left breast where the nipple ring hung.
"You only get what I choose to give you. You can never steal what I refuse to let go!"
[Ooh! Mommy looks like a total Queen!]
The girl Rin's eyes widened. She almost wanted to applaud. This was the Kaede she wanted to see! No more being humble while sharing her man; she should be marking her territory against these vixens!
Nino bowed her head, her shoulders trembling like a defeated knight. Her fists were clenched so hard her nails drew blood. Miku thought Nino was about to pounce.
"We will take him from you. And we will satisfy Ichika's kink ourselves!"
"Eh?" Nino looked at Miku in surprise. It wasn't her who spoke—it was Miku. The soft-spoken, weak-willed Miku was standing up to Kaede, staring her down without flinching.
If her little sister was stepping up, Nino couldn't back down. She stood up too.
"That's right! We'll take him and we'll satisfy Ichika! Hmph... as for you, you better be careful he doesn't turn you into a cuckqueen like Ichika!" Nino grabbed Miku's hand. "Thanks for the meal. We're full!"
The two sisters turned and walked out without looking back.
Kaede watched them leave with a look of pure pleasure. Plan initiated.
The five sisters were idiots. Such a simple provocation and they fell for it. Nino's reaction was exactly what Kaede expected. She had spent all night thinking about how to advance Ichika's "training."
Her plan: Murder with a borrowed sword.
There was only so much she could do personally without using the system for weird brainwashing. She and Ichika were just friends, so she decided to use the sisters to do the "training" for her. As sisters, they knew Ichika better and had more access to her.
They were idiots, but four idiots put together could surely come up with something. Even if it was a terrible idea, Ichika might be touched by their effort and actually fall deeper into her fetish.
Heh heh heh... as the mastermind, I just have to wait for the rewards to roll in! I've won it all.
