A guide to survival in a heavy girl's world

"Maybe it doesn't count anymore. After all, he has already said that he will cooperate with us."

Nagasaki Suyo moved her hands that were originally on Chihaya Tetsuya's legs and came to Chihaya Tetsuya's side.

"Even at the last moment, you still didn't want to give us all the responsibility of taking the initiative."

But it’s also good this way. For this guy whose entire personality is made up of dedication, this kind of two-way ending may be what he most hopes for.

and so……

“Even though the circumstances are slightly different, what we have to do is still the same.”

Nagasaki Suyo said:

"Well then, I'll leave it to you for now, Ai."

On this night that will determine everyone's future, the girl who has been with him since the beginning of the story is the first to turn the first page -

Chapter 150: Long-lasting and eternal love.

Compared to other people, the identity of adopted sister has brought Chihaya Aine conveniences that others can't even imagine.

She could freely use her status as a younger sister to get close to Chihaya Tetsuya and comfortably occupy the most intimate position beside him. For example, the first time they rubbed their knees together, the first time they took a bath together, these intimate interactions between couples, were all initiated by her as the stepsister.

Because of this, when Nagasaki Suyo and Toyokawa Shoko were still thinking about how to close the gap between them and Chihaya Tetsuya, she had already stood in the position of winner, leisurely waiting for these challengers to catch up -

Until these newcomers expressed their feelings to Chihaya Tetsuya at a speed completely beyond her expectations, and caught up with her and even surpassed her before she could react. The reason for this result, in addition to her own laziness, was precisely because of her identity as a "stepsister".

Chihaya Tetsuya's love and consideration for her had already become a natural habit, and her admiration for Chihaya Tetsuya had been established in her childhood. For this pair of siblings who have been together day and night for seven years, the intimacy and trust between them has long surpassed that of ordinary lovers.

This high starting point prevented Chihaya Aine from finding any room for further progress. Whether it was the touching reunion with Ai after a long separation, the peace of mind he and Suyo shared as they entrusted their futures to each other, or the unwavering trust between him and Xiangzi, these were all things she, as a younger sister, could not achieve.

At the same time, after actually coming into contact with these girls who had the same feelings as herself, Chihaya Aine immediately realized that the reason why she was so favored by Chihaya Tetsuya was simply because she was fortunate enough to become his adopted sister.

If she didn't have this identity... she would probably never have the qualifications to have such close contact with her brother as she does now.

"...I feel like the temperature difference is quite significant."

When Chihaya Aion sat in the position that Hoshino Ai had just taken, compared to Hoshino Ai's mixed feelings, Chihaya Aion's reaction was much calmer.

"It's so unfair for me to be ranked behind Ai, isn't it? Putting aside the difference in 'hardware'... I definitely can't do what she just did!"

As she spoke, she looked at Hoshino Ai's well-trained slender waist with admiration.

"Besides, I probably wouldn't be as selfless as Ai."

After all, for her, even if she was about to do the most intimate thing with her beloved brother, it was nothing more than a small step forward on the existing basis.

"Ah, this angle looks so familiar."

Chihaya Aine lowered her head and looked at Chihaya Tetsuya's face.

"I used to use this gesture to wake my brother up!"

"But the situation is completely different..."

Compared to Chihaya Aine's nostalgia, Chihaya Tetsu, who had just had a break from Hoshino Ai's fierce attack, was not so relaxed.

"Forget about the quilt. I'm only wearing a shirt right now... It doesn't make any sense no matter how you think about it, right?"

"what……"

Chihaya Aine was very surprised that her brother's feelings were completely different from her own.

She had originally thought that she, with her thin figure, poor skills, and the complete lack of stimulation due to the close relationship, would not be able to excite her brother at all. However, judging by her brother's honest physical reaction, he was obviously not as calm as she thought.

"Is this true? My brother can actually take such a big interest in me?"

Chihaya Aine was very surprised by this, and in order to further confirm the situation, she even reached out and touched it directly.

"Wow... this is amazing. So this is what it feels like."

“Aine…”

Faced with Chihaya Aine's evasive reaction, Chihaya Tetsu couldn't help but call her name helplessly.

"If you're not mentally ready, don't force yourself to do it."

"Well……"

Seeing that she was about to retreat, Chihaya Aine subconsciously looked away.

"Rather than being unprepared, I simply lacked confidence..."

Even though she had personally confirmed her brother's current condition and reaction, Chihaya Aine still didn't dare to take that step.

But there was no way around it. Compared to the idol Hoshino Ai, and the impressive figures of Suyo and Shoko, her physique was far too thin. As for actual combat, she also had no experience and lacked the confidence to properly please Chihaya Tetsuya.

Or... should I just leave it at that? Wait until I've accumulated enough experience from the other three people?

Anyway, even if I give up halfway, even if I fail to achieve that step, the distance between me and my brother will still be as close as before.

So, in order to avoid disappointing her brother, she decided to...

“Aine.”

Just when Chihaya Aine was about to back out, Chihaya Tetsuya suddenly said something that was completely beyond her imagination:

"If you really don't dare, it's okay for me to take the initiative next."

"……Eh?!"

He wasn't trying to persuade her to give up, or to comfort her or persuade her... but rather, he was the one who took the initiative to do it with her! ?

Upon hearing these words, Chihaya Aine was immediately plunged into deep surprise.

In her opinion, Chihaya Tetsu's willingness to cooperate with their antics was the biggest concession he could make. However, at this time, not only did he take the initiative to comfort her when she was about to back down, he was even willing to take the responsibility of being the initiator?

"The reason you want to do this with me is to take our relationship to the next level and dispel the anxiety in your heart, right?"

Chihaya Tetsuya said as he gently twisted his wrist.

The "rope" used to bind him was an elastic band with excellent elasticity. With a little force, he could easily break free.

"If that's the case, then there's no point in comparing anything in the first place, right?"

Then, as Chihaya Aine's face became increasingly red, Chihaya Tetsuya untied her hands and held her waist.

"Wait, wait, brother!"

Chihaya Aine's face suddenly turned red when her waist was suddenly held tightly.

"This time, I should be the one saying this. I don't think you need to force yourself to do something you don't like!"

She said:

"I know that even if I don't do this kind of thing, you will still pamper me and be responsible for me as always. So... you can do it with them first, and then come to me when you feel like it—"

"Aine, listen to me."

Chihaya Tetsuya suddenly raised his voice, causing Chihaya Aine to stop her self-denial.

"You might think I agreed to be your lover out of sheer inertia of our 'family' and 'sibling' relationships... but that's not the case."

As Chihaya Tetsuya spoke, he took the initiative to hold Chihaya Aine's hands.

"Think carefully, Aine. If I really only thought of you as my younger sister, then I wouldn't have exposed so many ugly behaviors in front of you before, right?"

"But... aren't those normal reactions for boys?"

Chihaya Aine turned her head away and muttered:

"I know that boys are very likely to have that kind of physiological reaction."

"It's not that simple."

But Chihaya Tetsuya shook his head:

"You've probably heard that I've come into close contact with fashion models more than once before, but I didn't react at all... I think you understand now, right? You're also a very attractive woman to me."

"Ah wow wow..."

So, compared to those voluptuous fashion models, my brother actually prefers her, who is ordinary and skinny?!

An indescribable sense of satisfaction and accomplishment instantly brightened Chihaya Aine's expression.

Chihaya Tetsuya continued to explain:

"Just like you couldn't consider other boys your age as romantic partners because of me, I also subconsciously compared the girls around me to you... and as a result, until we confirmed our relationship, I hadn't met anyone I was attracted to. So, to be honest, I might have already considered you as the opposite sex before you confessed your feelings."

Having said that, although Chihaya Tetsuya's tone was very embarrassed, he still took the initiative to speak:

"If you really can't believe it, then let me prove it to you."

"..."

Chihaya Aine never expected that Chihaya Tetsuya would say such surprising words to her in such an occasion.

Eh? Is this true? It turns out she's not the only one who's attracted to him. Her brother has always treated her like an ordinary girl?

Unprecedented joy made her completely stand still.

She really wanted to continue confirming with Chihaya Tetsuya when exactly he started to see her as that kind of person, and what exactly he liked about her.

But compared to this, the stirring voice deep inside her body told her that now was not the time to pursue these issues.

"If that's really the case, then... I'll leave it to you, brother."

Chihaya Aine turned her palm and clasped her fingers with Chihaya Tetsuya's:

"I wonder if I really have that kind of attraction to my brother that you just described."

……

Unlike Hoshino Ai at that time, at the beginning, Chihaya Aine did stop moving because of the sudden pain, and lay on Chihaya Tetsuya for a long time without daring to move. In order to comfort her, Chihaya Tetsuya kissed her cheek while waiting for her to adapt.

Just like how they have always gotten along.

Chihaya Tetsuya always does this in the most considerate and appropriate way, comforting Chihaya Aine, who has been repeatedly frustrated and hurt due to her immaturity, and encouraging her to move forward.

Soon, with the comfort of Chihaya Tetsuya, Chihaya Aine gradually came out of her pain and anxiety, and regained her hope and fighting spirit.

And then, out of her trust and attachment to Chihaya Tetsuya, she finally began to make her own efforts and began to strive to catch up with her most admired brother...

“…It’s become quite cozy.”

Nagasaki Suyo blinked:

"It's completely different from the style I just loved."

"This gradual progress is indeed very Aine-san's style."

Toyokawa Shoko also commented:

"And this way, Aine will become the first one that Tetsuya-kun has taken the initiative against."

"Yeah……"

Nagasaki Motoyo nodded and cast a somewhat envious look at the two people who had reached a complete understanding.

"The bond cultivated over the years as siblings is truly irreplaceable."

Even though there are still many feelings between the two that they have not yet understood, the warmth and harmony that emanates from their shared memories still makes Nagasaki Suyo, who longs for a home, feel very longing for it.

"You're talking as if it's someone else's business..."

At this moment, Hoshino Ai came to the two of them with a staggering step.

"Will you also have a relationship like this with him in the future? Instead of envying others, you should think about what you should do next."

"...You're fine now."

Seeing that Hoshino Ai had regained her ability to move, Nagasaki Suyo and Toyokawa Shoko immediately grabbed her.

“Come to think of it…did it hurt at first? Aine’s reaction was so intense, but you seemed fine…”

"I don't know either. At least I didn't feel any pain at all."

Hoshino Ai shook her head.

"And even if it does hurt, it will only last for a brief moment. Look at what Chihaya Aine looks like now."

“…”*2.

After saying that, the two of them looked at Chihaya Aine, who had already adapted to the pain. As expected, under Chihaya Tetsuya's initiative, Chihaya Aine's expression gradually changed from pain at the beginning to obsession and happiness...
