It was now the second weekend since the start of the semester. Five days had passed since Ichika and Miku formed their secret alliance. Their next objective: make Nino, Yotsuba, and Itsuki fall for Rin as well.
While they were determined to "steal" Rin as a team of five, Ichika and Miku wouldn't resort to moral blackmail like saying, "Mom said quintuplets should always be together." They planned to help Rin charm their sisters but wouldn't force them. Besides, Ichika and Miku themselves hadn't even been "eaten" yet, and they both shared a hunch—Rin might just charm the rest of the sisters on his own without their help.
Nanami didn't provide tutoring every day; between taking care of Mashiro and practicing her voice acting for Galgames, she was quite busy. Even on days without official tutoring, the sisters gathered at Ichika's apartment to do homework.
Miku had kept Ichika's supposed "cuckold" fetish a secret from the others. Nino, Yotsuba, and Itsuki were still in the dark, studying hard every day to prevent Ichika from finding out about their "affair" with her boyfriend. If they knew the truth, they'd probably stop caring altogether.
Today, Rin and Nanami came over to supervise their weekend homework.
"Professor Aoyama~ I'm done with my math! Check it for me~" Ichika handed her assignment to Nanami with a grin.
Nanami glanced at it. "You're improving... Take another look at questions three and five. Start with these simple mistakes and save the hard ones for later."
"Three and five? Since they're simple, I'll go ask Professor Rin. I won't bother you, Professor Aoyama~" Ichika hopped up and slipped into the bedroom to find Rin.
Nino pouted, feeling annoyed. They call it "consulting," but they're definitely in there making out!
Contrary to Nino's expectations, Ichika was actually being a diligent student for once. "Professor, teach me questions three and five."
"Let's see," Rin scrutinized the paper. "You messed up the second step of question three. It should go like this..."
The problems were easy for Rin. After ten minutes of explanation, he had Ichika repeat the logic back to him. Once he was sure she understood, he nodded.
"Rin, I probably won't be able to continue the tutoring sessions starting next week," Ichika said, her eyes twinkling. "My agency scheduled training sessions from after school until late at night."
Rin nodded thoughtfully. "You aren't like Nanami; you can't easily balance work and study. If you go, your grades will truly tank. And that's just training—if you pass an audition, you might not even have time for school. Think it over."
"Yeah..." Ichika leaned in, whispering into Rin's ear with a mock-tragic expression. "If I fail school and fail my auditions, I'll have no skills left. I'll probably have to do porn."
"..." Rin stared at her. We were having a serious life talk, and now you're talking about "going down into the sea"? Is she already acting?
"There are plenty of girls with better bodies and prettier faces than you. If you can't act, you won't even make money in porn."
"Even if my acting is bad, five quintuplets doing porn together would be a huge hit, right? But I guess I need some acting skills... Professor, can you coach me on my 'adult video' acting? Or... should I call the others in so you can coach us all at once?"
"Sure, go call them."
"Seriously, you never play along," Ichika laughed, playfully punching Rin's shoulder. She leaned in again. "Anyway, since you've already tasted Nino and the others' lips... when are you going to finish the job and conquer them?"
Rin raised an eyebrow. Ichika clearly knew because Miku told her. Did that wardrobe session actually develop a fetish in her?
"Do you really have a cuckold fetish?" Rin asked curiously.
"Of course not! I was just acting for Miku. I'm far more interested in 'stealing' you from Kaede than being cucked..." Ichika stood up, looking down at Rin with a triumphant tilt of her chin. "Kaede is far too trusting, leaving so many cute girls around you. Tell her to be careful, or I might just snatch you away."
"I'll tell her..." Rin reached out and swatted Ichika's ass. "Since you've decided to give up on grades, as your teacher, I have to punish you."
Ichika obliged by arching her back and winking over her shoulder.
Smack!
Through her skirt and panties, Rin slapped her firm, rounded cheek. The sensation was perfect. They often played these roleplay games as "acting practice," though because the apartment walls were thin, they never went beyond heavy kissing and groping. Rin didn't want to make too much noise while the sisters were right outside.
But he wasn't in a hurry. The quintuplets needed to be a complete set. He imagined them lined up, five identical girls presenting their asses for his pleasure. The thought alone was intoxicating.
For now, only Ichika was active. Miku was on their side, but she was too shy to be bold. However, the first hurdle was the exam in two weeks. Passing at least one subject wasn't just about grades; it was about showing Maruo Nakano that his daughters were in good hands, which would make things much easier in the future.
And... Maruo's daughters weren't the only ones he was looking after.
