NOTE: I ged the musical instrument that he learo the saxophone instead of the trumpet.

  "Just the two of us

  Building castles in the sky

  Just the two of us

  You and I."

  (Just the Two of Us by Bill Withers and Grover Washington, Jr.)

  As Ishigami sang, Chika pyed the piano, enjoying his voice before he started to blow his saxophone as the two began their duet.

  Piano and saxophone.

  The sweetest and most fun bination was when they eheir time together.

  As for why the two started to py a musical instrument, everything started on Monday after his trip to Yokohama, but somehow, Chika wao go to the musi.

  While Ishigami felt weird as it was the first pce they were together, he accepted her advance, especially since he hadn't been with Chika tely, even though she wished to be together. More importantly, she should be fine and have recovered, so he could go all out after this.

  So why the heck did they start a jam session instead of having done something as two lovers usually do?

  The ao that came from—

  Cp! Cp! Cp!

  After a moment of silehe audience of their session cpped their hands in amazement.

  Yes, Ishigami and Chika weren't alone. Instead, they had guests e to watch their jam session.

  "...Yuu, have you learhe saxophone before?"

  Yet, Chika ighe audiend asked Ishigami with the most solemn attitude that she had ever shown in her life.

  "..."

  Fag such a question, Ishigami tried to remain calm despite the tradi betweeone and her current appearanbsp;

  "...no, I just lear after I bought it."

  "Then, you are a prodigy...."

  Chika felt flicted since she knew well how hard it was to learn a wind instrument, yet somehow, her man was able to learn it in just a short moment!

  More importantly, his skill wasn't even lost to those street performers despite only learning it for a while, which showed his great skill!

  "Have you thought of being a professional, Yuu?"

  "No."

  "Ah, that's a shame."

  "Not really."

  "Why?"

  "I get closer to you this way, after all."

  "...."

  Chika took a deep breath, trying to stop the blush that was about to appear on her smooth cheeks, then looked at Ishigami with a gaze of admiration. "Yreat, Yuu. Even if we're like this, you seduce me."

  "...thank you."

  Still—

  "So, Kaguya-san, Hayasaka-san, you two kindly leave us now?"

  Yes, if there was a reason why Chika tried to hold off instead of jumping to her man like a nympho, it was because there were Kaguya and Hayasaka, who came to look at their jam session!

  "The you do something lewd in this room again?" Kaguya looked at Chika with a helpless gaze.

  "We won't do such a thing!" Chika suddenly pointed her fi her headband. "Look! What word is written here!"

  "...demon?"

  "That's right!" Chika nodded in satisfa. "At this moment, I am a Demon Instructor, Chika! I will train Yuu so hard that he won't have dirty thoughts about me! Please believe me!"

  Yes, if there was a reason why Ishigami tried to trol himself instead of ret this silly woman, it was because Chika tied her smooth, pink hair in a ponytail and put on a headband with the word "demon" on it.

  It was said that she was a demon instructor, but Ishigami knew well that as long as Kaguya and Hayasaka left, Chika would bee a silly yet lewd succubus who would suck her man's dry!

  Yet, Ishigami khat Chika wasn't the only succubus since Hayasaka, who sat o Kaguya, was also a succubus!

  He wasn't sure whether Hayasaka's act was an act or deliberate, but she opened her legs, showing him the inside of her short skirt and white, smooth legs clearly toward him with a slightly disdainful expression on her face as if she was disgusted by his eyes that kept staring at her legs, yet instead of hiding them, she opehem wider, so he could see better, which made him felt... se since being such a gaze should make him annoyed, yet why did he feel strangely excited?

  Somehow, whehought she showed su expression for him, yet obediently opened her legs for him, trying hard to ehe pleasaions on her body... he felt like... he should bring her out ter.

  Still, Ishigami didn't have a strange hobby. Instead, at this moment, he was quite worried about a certain possibility, especially when he saw Kaguya was there. After all, he knew from Shirogahat the two would go out together on the weekend, and as this outing was the third time, Shirogane would fess his feelings.

  So, why was Kaguya by their side instead of going to Shirogane's side?

  A certain thought emerged within his mind, but Ishigami decided to remain blind about this. He khat this was wrong, yet... he let out a long sigh inwardly.

  Still hearing Chika's answer, Kaguya only stared at Chika and asked, "Are you sure that you won't do anything strange?"

  "....."

  Chika blushed, realizing that her dirty thought was exposed.

  Yet, could she be bmed?

  When Ishigami blew the saxophone early as they eheir time together, Chika had to admit that her womb trembled, thinking of something that she shouldn't do.

  However, like Eve, who had learned a forbidden knowledge from the devil, she couldn't trol her desire, and... everything was clear, right?

  "But Chika-san is right." Kaguya looked at Ishigami and asked, "Have you ever thought about being a professional, Ishigami?"

  "No, I am not. I'm fih just pying as a hobby, and I will just py for my family."

  "...."

  "...Chika-san, you not do something lewd when there are the two of us here?"

  When Kaguya saw Chika suddenly kiss Ishigami's cheek happily, she couldn't help but pin.

  "It's fine. You know about us anyway, so it doesn't matter."

  "But that doesn't mean that you do something like that, okay?"

  "If you don't feel good, then how about you get a man, Kaguya-san? It's nice, you know?" Chika smiled teasingly, but whehought that Kaguya should date a certain someone, she didn't feel good when her best friend was taken by someone else, so—

  "Ah, no! Kaguya-san 't have a boyfriend! Kaguya-san only be mine!"

  All of a sudden, Kaguya was hit by immense pressure, yet instead of being hurt; she felt so fortable all over sinstead of something hard, what weled her was two softness, which was impossible for her to produbsp;

  'This softness...'

  While Kaguya felt gloomy, she also had to admit Chika's softness felt so fortable, and she uood why Ishigami was in love with Chika.

  Still, as Chika hugged Kaguya, she looked at her man and asked, "Yuu, are you free ter?"

  "..."

  Watg the excitement and clear lust in her eyes, all of them khat Chika hadn't given up, but Ishigami khat he had to disappoint her and told her to use her hands first since—

  "Sorry, I have to go out with my father ter."
