In crossover anime, who isn't a childhood friend?

"Why?!" Eriri asked, her voice trembling with emotion.

She wasn't particularly smart to begin with; she was on par with Rikka.

With Chiya's hints, Yukino and Saeko were able to deduce most of the cases that occurred during the day.

She could only sit with Rikka, her hands tucked in her sleeves, her face blank, waiting for an explanation and to be fed. Otherwise, there was no way to understand the whole picture of the case.

Therefore, the current situation is also particularly puzzling to her!

Saeko explained naturally, "Well, there was a little unexpected situation. To put it simply, Utaha seemed to be in a more urgent need than I was today, so I temporarily gave in and let her start first."

"Don't make it sound like you're casually offering the other person cake!" Eriri couldn't accept that at all!

Saeko looked apologetic: "Should I have told you in advance? But I don't think it really matters to you, Eriri. After all, you probably only chose to observe tonight and didn't intend to join in. If you're really looking forward to it, I can find an opportunity to invite you to join us tomorrow night, instead of just watching from the sidelines like this."

"I...I'm not really looking forward to it!" Eriri quickly denied it!

Saeko's gaze drifted to the side: "That crack..."

Eriri's confidence waned: "It was just out of curiosity...that's all!"

"Oh, I misunderstood." Saeko's face now showed a perfunctory, appeasing expression that said, "Since you insist on saying that, then let's just assume that's the case."

Well……!

Eriri, realizing this, cried out inwardly.

What bizarre things have happened tonight, from the beginning until now!

Is this really the kind of story a normal high school girl with only slightly unusual hobbies in private should encounter?!

I'm on Earth, right?!

Why do I feel so oxygen-deprived? My brain feels like it's going to explode!

"Eri, have I caused you any trouble?" Saeko asked cautiously.

"No..." Eriri hugged her head, trying to stabilize it with physical means, and answered somewhat reluctantly, "...My head is just a mess right now."

She instinctively tried to look away, but as soon as she moved, she realized that the two of them were lying on their sides facing each other, and it was not easy to turn her head to avoid them.

So she could only slowly lower her head.

She also caught a glimpse of the deep cleavage beneath Saeko's loosely fastened yukata, which made her feel even more sorrowful.

Although we've seen it before when we've all been soaking in hot springs together.

But the laughter and jokes they shared back then couldn't compare to the bizarre situation they were in now.

I feel like my mindset has become more and more tragic!

Seeing Eriri's reaction, Saeko thought for a moment and said, "I'm sorry, I've been considering things from my own perspective all along. Perhaps I've overlooked many things about you, Eriri. So if I've offended you in any way, you can tell me directly."

As always, Saeko Busujima had a very good attitude, being kind and gentle to everyone, which is why she was able to earn so much respect from everyone at school.

But the problems we face now cannot be solved simply by these personality traits.

Eriri muttered very softly, "I've never felt that you've done anything bad to me, Saeko-nee, let alone offended me. I just..."

"Mmm—uh—"

A soft, high-pitched groan, suddenly abruptly suppressed, interrupted Eriri's quiet mutterings, sounding exceptionally clear in the still night.

Those alluring moans drifted intermittently from Qianye's room, accompanied by Shiyu's somewhat uncontrollable, yet clearer, reproachful voice: "You bastard, who let you in without permission!"

Her voice wasn't particularly loud, but it was enough for Saeko and Eriri, who were in the next room and remained conscious, to hear it.

And maintain it at a subtle level that won't wake a sleeping person.

Eriri's heart, which had just calmed down a little, started beating at double speed again after realizing that something had already happened!

"It seems they've started over there." Saeko leaned close to Eriri, their foreheads almost touching. "We can talk about our problems later. As for now, this is a rare opportunity, so let's see what happens."

Look what this is! And why do you always say things that are completely unexpected, Saeko-nee?!

"I...I..." Eriri's face turned bright red, feeling that if she continued like this, she would become half-cooked from the heat.

Saeko softened her tone considerately: "Yes, I understand. Eriri isn't interested in this situation, but it's always a rare opportunity to observe a real battle. There's a professional term in the painting field called 'model photography'."

I don't know much about this, but Eriri, you should know very well that artists like you sometimes need to find real models to practice drawing on-site in order to improve your drawing skills. This is a necessary thing.

Therefore, considering all of the above, isn't this current situation a hard-won opportunity for you?

Saeko's calm words seemed to possess a hidden magic.

Mingming's words clearly violated moral principles and ethics, and were obviously far-fetched. It felt like he was promoting some strange doctrine, which was very problematic!

But Eriri just couldn't bring herself to argue or refuse!

She can deceive others with words and actions, but she can't deceive her own heart at all.

In private, she uses all her brainpower to imagine the hidden inner workings of Chiyo. In the dead of night, she locks her bedroom door, puts on her glasses, and lies on her desk, frantically staring at the gradually clearing drawings she is sketching, transforming into a madwoman!

No...no, please!

Don't let desire break down your will!

Be more reserved... and firmly refuse Saeko-nee!

Eriri wanted to reprimand her loudly, but the suggestion she made was just too much.

As Saeko suggested, and with Saeko's half-hearted encouragement, Eriri's body eventually turned back uncontrollably.

His eyes met the crack in the door again, just like before, and he began to peek into the room next door.

Unlike before, now that Saeko was watching with her, and she realized that others were doing the same thing as her, the guilt she felt was halved due to the herd mentality, which made Eriri's complicated emotions less intense.

But as expected, this is the situation now...

Along with his childhood friend, his first official girlfriend and a senior he admires, they secretly watch him being intimate with another woman he's also dating late at night...

Things are getting weirder and weirder!

Even the most imaginative adult doujinshi don't have such an outrageous plot!

Witnessing firsthand the man she's liked since she was little being used and exploited by that stinky woman she hates the most...

Why do I have to do something so incredibly pathetic here?!

Eriri asked herself these questions, but found no answers.

And most tragically—

Eriri turned her gaze back to the scene, and despite her constant wavering, she couldn't tear her eyes away from the two entangled figures, and this only made her more excited...

I've definitely broken down in some way...

In addition to the previous one, there is now an additional role of an interpreter, who seems to understand the store that Eriri cares about most, and takes the initiative to explain it to her.

"Ah, although it's not very clear, they seem to feel it's about time and are ready to begin."

"Shiyu seems to be in a pretty good mood today."

"Eri, look, Chiya's actions just now were probably safety precautions he took proactively. He's really quite meticulous in this regard."

"Although you didn't consider this aspect most of the time in the sketchbooks you drew, sketchbooks and reality are still incomparable. There are some things you absolutely cannot take chances with."

"Ah, it's officially starting..."

"Shiyu's health has never been very good. Is it really okay for her to be so proactive today? It's worrying..."

"Ah, sure enough, she ran out of energy in just a few minutes. I've been trying to persuade her to exercise with me, but she never takes it seriously. If she's always slacking off, it's bound to have this kind of consequence at such an important time."

“Eri, look, Chiya is very gentle, isn’t he? He understands Shiho’s physical condition, so he’s very considerate in letting her rest for the time being.”

"By the way, speaking of doujinshi, there's something I've been wanting to tell you in person, Eriri."

Finally... finally!

Saeko's words finally reached a point where Eriri could follow along!

Eriri was so moved she almost cried!

Although topics like doujinshi are quite indecent and shameful, it's still much better than secretly observing them in a particularly sad way while giving specific opinions!

"I've been following Eriri's doujinshi."

“Hmm…” Eriri responded softly.

Saeko had confessed this to her a long time ago, and based on the content of her doujinshi featuring a tall, handsome, and strong male protagonist and a petite girl with twin tails, we could easily deduce her true feelings.

"Your drawing skills have improved a lot lately, that's undeniable. However, I don't understand if you're aiming for exaggerated visual effects or something else, but there are some parts that I find strange."

"Wh...what happened?"

"For example, here."

"Huh—!"

Eriri, who had been secretly observing the practical exercise from the very beginning, felt her extremely sensitive lower abdomen being gently pressed against in a delicate spot by Saeko's fingertips from behind.

"Oh, I'm sorry, Eriri, do you not like being touched by others?"

“That’s not it… I was just startled… It’s okay… Saeko-nee, you, you continue.”

"Simply put, it's like this: in this position, no matter how skilled someone is, there won't be any raised marks." Saeko drew circles, explaining her own experience: "Take Chiya and me as an example. He's very skilled, I feel he's even more skilled than the male protagonists in the stories you draw, Eriri, but even so, it won't show up in this place close to the skin."

"Oh... I see..."

I don't know whether to call it useless knowledge or not.

"But there are some parts that you drew very well, Eriri."

"Is that so..."

"Well, for example, when a girl is most emotionally agitated, her bodily functions may temporarily go out of control, she may not be able to control her expressions, she may shed tears, and she may also leave behind some other things. And then there's... this place."

Saeko's hand moved down a little, resting on Eriri's lower abdomen, just below the chin.

"...This is knowledge that wasn't taught in health courses. I only learned about it through my own experience, just like the perspective view that you use in your book when the story reaches its climax."

When a girl experiences unparalleled emotional and physical satisfaction, she may indeed feel a strong urge to embrace due to the emotional and psychological impact.

Actively welcoming them is a bodily instinct, an instinctive desire to possess everything from the person you love most, and to bear their offspring.

"Well……"

Eriri curled up, pressing her legs even tighter together.
