"Ugh... mm..."
The full moon's glow pierced through the window, scattering across Yoshikawa Aina's contorted little face.
In another world, the girl was watching an age-restricted action movie, and the three actors were surprisingly her most familiar Pab club companions.
"Mhm mhm mhm! Not there... playing like that is too advanced!"
Clutching the bed sheet tightly over her chest, Yoshikawa Aina sat up abruptly while wildly flailing her other hand. A large amount of sweat instantly soaked her tank top.
Gasping for breath, her pupils contracted to pinpoints as she scanned the room. As her eyes gradually adjusted to the darkness, she realized that everything just now was only a dream.
However, perhaps because she was too familiar with Yu's naked body, this dream was a bit too real, feeling just short of an immersive experience—only lacking her personal participation!
"Ugh... this won't do. I'm so curious, what are Azusa-senpai and the others doing..."
Tears welled up in the corners of her eyes. Recalling the dream just now, Yoshikawa Aina's face flushed red, and she curled up her body, clutching her head and scratching frantically.
Even though she was awake, the age-restricted plot, far beyond her years, kept replaying in her mind. All sorts of strange moans and groans made it impossible for her to calm down.
Helpless, unable to fall back asleep even after retreating into the covers, she could only turn to Chisa's bed.
"Chisa? Are you still awake..."
"...Awake."
Chisa Kotegawa's resentful voice came from under the covers, her eyes bloodshot.
Although it was Azusa-senpai who was asleep, since Yu had gone so far as to be utterly insane, it wasn't impossible for him to directly go after Nanaka-nee!
With her own sister possibly doing strange things next door, how could Chisa possibly sleep!
"Um, if Chisa is also very curious, how about..."
Seeing that Chisa was also tormented by her investigative curiosity and couldn't sleep, Yoshikawa Aina immediately ran barefoot to the former's bedside and suggested eagerly: "Let's go on a night raid!"
"A night raid!!?"
Startled by Aina's idea, Chisa Kotegawa hesitated and sat up in bed, her large orange eyes filled with conflict.
Speaking of night raids, she had indeed seen Azusa-senpai sometimes secretly sneak into her sister's room and then leave contentedly after more than half an hour.
But if she were to do it herself, the moral bottom line that hadn't been completely corrupted by the Pab club still made her feel shy.
Moreover, if it were only her sister and Nanaka-nee in the room, it would be one thing, but Yu was also in the room!
If she accidentally saw something she shouldn't see...
"Hiss... even if I saw something I shouldn't see, it might not matter!"
Sucking in a cold breath, recalling that Yu often went skinny dipping under the moon with Tokita-senpai and the others, Chisa Kotegawa held her chin, and her eyes instantly became indifferent.
After all, she saw it often in plain view. It was just the difference between dynamic and static!
"Hmm? What shouldn't you see?"
"Nothing..."
Pulling the blanket up to cover the lower half of her face, Chisa Kotegawa closed her eyes and spent three to five minutes preparing herself mentally, then suddenly opened her eyes with a determined look.
"Let's go, Aina! We're going on a night raid!"
"Mhm!"
Finally finding an accomplice, even if Chisa hadn't agreed, Yoshikawa Aina had already made up her mind to secretly explore Yu's room at night.
Unless she saw an indescribable scene and her brain crashed and she passed out completely, she was definitely not going to sleep well tonight!
"Clack!"
A sudden noise appeared in the quiet villa. The door latch was turned, and two sneaky little heads peeked into the corridor, looking around with a very guilty air.
Confirming that there was no movement in the boys' dormitory next door, Yoshikawa Aina and Chisa Kotegawa padded barefoot out the door, moving nervously to the bedroom near the swimming pool.
Placing her hand on the doorknob, Chisa Kotegawa took a deep breath, closed her eyes, and pushed the handle down with a click!
"Hoo... hoo... hoo..."
Her arm, along with her fingertips, was trembling. Seeing Chisa making a significant amount of noise, Yoshikawa Aina carefully pressed her ear against the door, trying to pick up sounds from inside the room.
As soon as anyone inside noticed anything unusual, she would immediately use diving hand signals to notify Chisa to retreat.
And inside the room at this time...
"Mmm... so stuffy, so hot..."
Lying on the bed, Miyazawa Yu's eyes were tightly closed, and his expression was not peaceful. Large beads of sweat flowed from his forehead all the way down to his cheeks, and then...
And then there was no "then." A great wickedness directly clamped the lower half of the boy's face in the middle, which was delicious but also brought super high heat.
Not only that, behind him, the orange-haired beauty who liked to hug something while sleeping had clearly used him as a body pillow.
Muttering "little Chisa" constantly, Kotegawa Nanaka's eyes curved into a contented line, and her slender but powerful arms tightened again, squeezing Miyazawa Yu firmly into her embrace.
In the middle of summer, three people crowded together, with breathing and body temperature constantly rising from the contact. To describe it as a heat bomb would not be an exaggeration!
But unfortunately, under the effect of the sleeping pills, the only resistance Miyazawa Yu could offer was to grope and take a few liberties, while unconsciously throwing off his underwear!
"...No sound?"
"I'll continue then!"
The door, fitted with soundproofing material, instantly refined the faint, unconscious murmuring, making it impossible for Aina outside the door to make a firm decision.
However, stalling here forever wouldn't solve anything. Chisa Kotegawa's eyes sharpened, and she began to try pushing the door open.
Even if they were discovered, it didn't matter. They could just say they wanted her sister to sleep with them. What's wrong with a sister acting a little spoiled!
"Hmm? I can't push it open?"
However, as Chisa gradually increased her strength, the two of them immediately discovered a serious fact—
The room door seemed to be blocked by something from the inside, and Chisa's strength alone couldn't even force it open!!!
"No way, how can that be?"
"It might be that guy Yu moved the wardrobe over. After all, the solid wood furniture in this villa is quite heavy."
"Ah~ so that's how it is... Wuwu!"
Looking at Iori's head popping out from behind, Yoshikawa Aina suddenly realized halfway through her thank you that he was there.
But before she could gasp in surprise, Kohei Imamura grabbed her mouth from behind.
"What's the status of the investigation?"
"There are no unusual sounds in the room, everything else is unclear..."
Completely unaware of when these two guys had snuck up behind them, Chisa Kotegawa, with her half-moon eyes, briefly described the situation to the two serious-faced men.
After hearing Chisa's description, Iori Kitahara solemnly crossed his arms and summarized: "In other words, there is absolutely no evidence that Yu hasn't taken action. That's how it can be explained, right?"
"Mhm! The soundproofing in this villa is very good. Muffled whimpering sounds won't escape!"
"So how do you two know so clearly?"
Casting a suspicious look, having recovered from her panic, Yoshikawa Aina immediately caught the loophole in Kohei's words.
You must know that this kind of detailed description could only be discovered by performing an experiment!
Moreover, Kohei's description was too vivid. She could now imagine Azusa-senpai being gagged, her beautiful violet eyes rolling back in their sockets, dammit!!!
"Ugh... although it's shameful to say it."
"But actually, we already conducted the experiment!"
A bolt of wisdom flashed in his eyes with a pika, Iori Kitahara proudly pointed to Kohei and explained: "As long as his mouth is covered, even if Kohei screams until his throat breaks, no one can hear it!"
"Ah, I see."
"That must have been tough on you..."
Cold sweat ran down her forehead, and Chisa Kotegawa's expression instantly became full of disgust.
After all, Yu and Azusa-senpai interacting like that could still be explained as indecent behavior, but as for Iori and Kohei...
The scene of Iori laughing wickedly and covering Kohei's mouth and nose, while the latter writhed his pale body and two lines of humiliating hot tears streamed from the corners of his eyes, flashed in her mind.
Chisa and Aina pulled long faces, feeling that their minds had been forcefully violated, the kind that diving couldn't cure!
"Um, in that case, how can we figure out what's happening in the room?"
"Well..."
Taking one last look at the door, Iori Kitahara seriously crossed his arms and explained: "It's definitely useless to try from the main door. That guy Yu has extremely strong security awareness and must have prepared for our night raid!"
"But! Don't forget, even a room on the second floor definitely has more than one entrance and exit!"
Similarly pretending to be profound, and flipping his blonde hair, Kohei Imamura struck a strange JoJo pose and pointed a finger at the corridor window, under Aina's expectant gaze.
"That's right! We can also enter through the window! That way, if Yu is doing something bad, he won't even have a chance to cover it up!"
"Ah, it looks like you've been planning this for a long time!"
"He's definitely a scumbag, no doubt."
To carry out a premeditated night raid so openly, they were truly worthy of being the Pab club's twin stars, running neck and neck with Yu!
However, besides their suggestion, Chisa and Aina truly couldn't think of any other methods for the moment.
...
Ten minutes later, outside the villa wall, looking at Iori and Kohei, who had braced their hands and were ready to be stepping stones at the base of the wall, Chisa Kotegawa looked nervous and started to run up under the moonlight.
"I'm coming!"
"Don't worry, Chisa! Charge right at us bravely!"
"As your best friends, we will make you fly high!!!"
"Hah!"
Accelerating her sprint, Chisa Kotegawa ran with her long legs, determined to witness it with her own eyes, even if her sister had fallen, so she wouldn't have to constantly worry.
Passing Aina, who was full of anticipation, passing the swimming pool that reflected the moonlight, she leaped up like a goddess under the moon.
At the same time, Iori and Kohei overlapped their hands to form a platform for leverage, gritting their teeth and gathering all their strength in their arms.
As Chisa's small feet stepped onto their hands, the two simultaneously yelled: "Don't underestimate the bond between us! Fly high!!!"
"Swish—! Slap!"
Putting her hands on the wall edge of the second floor, Chisa Kotegawa used the leverage to flip half her body onto the protruding architectural structure beneath her sister's bedroom window sill.
Reaching down, Aina was then pulled up, followed finally by Kohei and Iori.
"Heh, heh hahaha!"
"Kohei, your clothes are all dirty!"
"You're one to talk, Iori! Have you figured out how to explain the stained underwear to Nanaka-nee?"
Leaning on each other, the four exhausted people suddenly found the other's dishevelled appearance hilarious.
Working hard together for a common goal, even if it looked like utter foolishness to outsiders, to college students, this was the symbol of friendship!
"Alright! Everyone look now! What is Yu doing!"
"Mhm!" X3
Having come this far, they naturally couldn't forget the main task. Encouraged by Iori, the boys and girls, each with their own secret agenda, simultaneously peered toward the window.
However, the next second, the smiles froze on their faces.
The window, which should have been open in the summer, was completely locked, and the curtains were drawn tightly, leaving only a note for the invaders—
[The area ahead, let's explore it next time! (Girls look here)]
[Get out!!! (Iori and Kohei Special)]
"What the heck!!!"
"What's going on!"
"That bastard Yu!!!"
Under the moonlight, wails rose and fell along the Izu seashore...
