A guide to survival in a heavy girl's world

Just when Chihaya Tetsuya, who was forced to lie on his back, was still confused by Chihaya Aine's behavior, the next second, Chihaya Aine's hands reached out to his ears at the same time.

"!!!"

So, she was planning to attack from two directions at once! How despicable!

However, before Chihaya Tetsuya could utter a word of protest, the numbing sensation that came from both ears simultaneously and the friction sound that almost occupied his entire hearing sense directly deprived him of the right to speak normally.

The feeling was completely different from just now. Under the dual stimulation of touch and hearing, Chihaya Tetsu felt that his brain had become blank, leaving only the comfort he had never experienced before.

On the other side, when she saw Chihaya Tetsuya's eyes becoming a little dazed, Chihaya Aine also felt that the weight on her legs seemed to have become a little heavier than before.

It turned out that in order to reduce the pressure on his thighs, he had been quietly raising his neck...

"Really? You have absolutely no intention of relaxing!"

Chihaya Aine complained somewhat dissatisfiedly as she was determined to make her brother relax.

"I've already said I'm going to heal you properly, so why don't you trust me a little more... Oh?"

The next second, when she noticed Chihaya Tetsuya's slightly dazed expression, she immediately thought of how to "punish" this unromantic brother -

"It looks very comfortable! So what do you think?"

"!?"

As Chihaya Aine put his fingers into his ears, Chihaya Tetsuya, who was about to regain consciousness, suddenly relaxed again.

The feeling of friction on his earlobes alone was enough to make him unable to resist, not to mention the simultaneous attacks from both inside and outside.

"Since you won't relax, I'll make you so comfortable that you'll have to relax!"

Seeing Chihaya Tetsuya unable to extricate himself, Chihaya Aine suddenly felt an unprecedented sense of conquest and satisfaction rising in her heart.

(I've always been the one-sided carer, but now I can finally do something for you...)

Just by seeing Chihaya Tetsuya's expression of struggle and enjoyment, Chihaya Aine's heartbeat accelerated uncontrollably.

(Come to think of it…my brother, who has always been so handsome and reliable, can actually make this kind of expression.)

Chihaya Aine, who originally simply wanted to make her brother more relaxed, suddenly had other thoughts in her mind.

This was the first time she faced this question again since that dangerous night - were the feelings she had for Chihaya Tetsuya really just the love between brother and sister?

This is clearly not the case.

Otherwise, she would never have felt that level of anxiety and "torment" when she slept in the same bed with Chihaya Tetsuya that night.

And now, just looking at Chihaya Tetsuya's face so close to her, she couldn't help but feel her heart beating faster.

Although she had always had great respect for her mature and reliable brother before, at this moment, when she saw with her own eyes that Chihaya Tetsu was so defenseless and allowed her to manipulate him at will, the thing in her heart that had been suppressed by "respect" and "trust" was finally revealed.

(I see……)

Chihaya Aine muttered silently in her heart as if she had just woken up from a dream:

(This is probably what prompted Hoshino Ai to do that...)

This "vulnerability" that contrasts sharply with his usual calm and handsome appearance, as well as his "innocence" that is completely unaware of his own charm and completely defenseless against others, is so sweet that even her younger sister can't help but want to do something bad to him.

Not to mention Hoshino Ai, who has been harboring a crush on Chihaya Tetsuya since seven years ago.

So, what should we do next?

Should she suppress this feeling again and continue to play the role of the obedient sister, or let her desires run wild like Hoshino Ai and launch an offensive against her brother as passionately and madly as she does?

What kind of relationship does she want to have with Chihaya Tetsuya? And what does she want from Chihaya Tetsuya?

Looking at the face in her arms that made her extremely obsessed, Chihaya Aine fell into deep thought.

Chapter 45 The final right of interpretation belongs to my sister.

After that dangerous night, when Chihaya Aine found out the deeper meaning of the word "hug" that Hoshino Ai said, her first reaction was not absurdity or confusion, but a sense of awakening as if she had suddenly been enlightened.

It is true that her relationship with Chihaya Tetsuya was misunderstood by her classmates during junior high school, but this misunderstanding was simply due to lack of understanding, so Chihaya Aine never regarded it as a big deal.

But Hoshino Ai's situation is completely different. Not only does she know about the relationship between the two, she also knows Chihaya Tetsuya's serious and responsible character. But even so, she still had such an outrageous misunderstanding.

What does this mean?

(This means that in Hoshino Ai's eyes, my brother and I really have the possibility of becoming that kind of relationship.)

When Chihaya Aine realized this, she no longer cared about Hoshino Ai's extremely offensive words, but was deeply intoxicated by the new relationship that was about to emerge -

(I... could also date my brother and... do that kind of thing with him.)

From the first day Chihaya Tetsuya walked into her home, she, already sensible enough, knew the truth that they were not related by blood. However, due to her parents' teachings and her own curiosity and kindness towards Chihaya Tetsuya, she completely ignored the blood relationship and treated him as her real brother. Chihaya Tetsuya, who had always longed for family affection, devoted unreservedly to Chihaya Aine the love that far exceeded that of an ordinary sibling.

This kind of life lasted for seven years. She gradually adapted to this comfortable and happy relationship and subconsciously believed that this relationship would last forever.

Until Hoshino Ai appeared in front of her.

She broke into the originally peaceful life between the two people in an extremely domineering manner. Not only did she forcefully declare her love for Chihaya Tetsuya, but she also suddenly made many other girls appear around him.

Because of Hoshino Ai's work on her first performance costume, Chihaya Tetsu also met Toyokawa Shoko.

Because of Toyokawa Shoko, Chihaya Tetsuya learned about the past of [CRYCHIC] and got to know Sankaku Hatsuka and Wakaba Mutsu.

At the same time, because of the idea of ​​forming a band, Chihaya Tetsu also met everyone from [MyGO!!!] and formed a deep bond with them.

Chihaya Aine, who had originally worried about her brother ending up alone, suddenly found herself surrounded by many lovely and talented women. Although Chihaya Tetsuya had repeatedly promised that he would never leave her and that the bond between them would last forever...

But the problem is that Chihaya Aine, who has already entered her prime, has actually long been dissatisfied with this kind of relationship.

That night, when she and Chihaya Tetsuya were lying in the same bed, she could clearly feel that her body was involuntarily attracted to Chihaya Tetsuya. If Chihaya Tetsuya had not reminded her that her already excited body was sweating, she would have continued to cling to Chihaya Tetsuya and asked for further intimacy.

But at that time she didn't get any "guidance" from Hoshino Ai, so she just regarded this excitement as the joy of not sleeping with her brother for a long time, rather than the desire to go further.

And now, when she noticed the changes in Chihaya Tetsuya's body, the heat that once surged through her body reappeared.

This time, she will not suppress it with so-called "legitimate" reasons.

"..."

Chihaya Aine slowly extended her hand from his ear to his cheek and neck, and continued to grope downwards.

It wasn't until she reached out and unbuttoned the first two buttons of Chihaya Tetsuya's shirt that Chihaya Tetsuya finally recovered from the excitement and couldn't help asking:

“Aine… you, what are you doing…”

“It’s a massage.”

Perhaps because she had just taken a shower, the blush on Chihaya Aine's face did not alert Chihaya Tetsuya.

"This kind of proper friction can promote microcirculation. Brother, you don't have to worry about anything. Just close your eyes and enjoy it."

"That's it..."

Out of his complete trust in Chihaya Aine, Chihaya Tetsuya did not question this statement.

And in order to avoid seeing Chihaya Aine's defenseless and dangerous appearance at this moment, he had no intention of opening his eyes.

Even though the pair of hands that were gently kneading my shoulders seemed to have a tendency to continue groping downwards...

"Then I'll leave it to you... But just press it for a while, I want to take a shower later."

(Today, I'd use slightly cooler water.)

In order to restore his restless body to its former calmness, Chihayatetsu also thought in his heart.

However, the next second, Chihaya Aine's words almost made him fall down——

"That's perfect, I'll rub your back later!"

Chihaya Aine's excited voice reached Chihaya Tetsuya's ears.

"Just like when we were two kids!"

"……Eh?"

Chihaya Tetsuya was stunned at first, then he quickly said:

“How can this be possible? Aine, you’re not a child anymore. We can’t take a bath together anymore—”

"I'm not taking a bath with you, I'm just scrubbing your back, just like my mother always does for my father."

Chihaya Aine said:

"It's normal for family members to help each other rub their backs. And if you really care, brother, then wouldn't it be okay if you just don't look back?"

"This one……"

When Chihaya Aine brought up the excuses of her father and mother, Chihaya Tetsuya's judgment was further disturbed.

If you're a family, and it's just a back rub or something, there really doesn't seem to be anything to worry about!

Just like Aine said, as long as he doesn't look back and covers himself properly with a bath towel, there shouldn't be any problem, right?

But then again, the reason why my father and mother could do that...was it really just because they were "family"?

Just when Chihaya Tetsuya was hesitating about this, Chihaya Aine's next words immediately shattered his last unformed doubt.

"Or are you actually worried, brother, whether you will do something you 'shouldn't do'?"

"certainly not!"

Chihaya Tetsuya subconsciously opened his eyes after hearing this and said eagerly:

"I would never do something so irresponsible to you!"

"That's it, isn't it?"

Chihaya Aine lowered her head and looked at Chihaya Tetsuya with a smile.

"If that's the case, then why are you hesitating? This is just ordinary 'comfort' from your sister."

Feeling Chihaya Tetsuya's skin which was also gradually heating up, Chihaya Aine couldn't help but chuckle in her heart.

(I now understand why she is so hostile towards me.)

As long as she used the excuse of "sister" and "family affection", Chihaya Tetsuya would tolerate almost all of her actions. Even if she touched or caressed him in such a vulgar way, he would not have any complaints or doubts.

When we get to the bathroom next time, how far will he tolerate himself going?

With a heart full of curiosity and anticipation, Chihaya Aine quietly pushed open the door that could never be closed again once opened.

Chapter 46 The most cunning identity.

【My brother has no intention of dating anyone at the moment.】

Because this topic had been discussed beforehand, Chihaya Aine had a very clear understanding of it.

Because of this, even though she now understood that her feelings for Chihaya Tetsuya were not simply family affection, she did not intend to confess her feelings to him directly.

My brother is a very serious and responsible man. Once I really confess to him, he will be caught in a dilemma due to his responsibilities as an older brother and his obligations as a man.

Chihaya Aine did not intend to embarrass her brother, nor did she want to be a burden to him, but at the same time, the desires and feelings in her heart that had been suppressed for who knows how long and were suddenly released now needed a suitable outlet.

Fortunately, unlike Hoshino Ai, she has another method that no one else can replace. It allows her to enjoy the treatment of a younger sister while retaining a cunning identity with infinite possibilities.

Stepsister.

As long as she is still Chihaya Tetsuya's adopted sister, she can continue to stay as close to him as possible with peace of mind.

As long as she remains Chihaya Tetsuya's adopted sister, she can always extend this relationship further and turn it into another identity that allows her to accompany him for the rest of his life.

As long as she is still Chihaya Tetsuya's adopted sister, then she is allowed to use his lap as a pillow, rub his back, or even sleep in the same bed.

In fact, if Chihaya Tetsu doesn't mind, even if it's just the last step, Chihaya Aine will gladly accept it...

Of course, that kind of thing is impossible.

After all, Chihaya Tetsuya would always refuse to even use a lap pillow, let alone such a big thing.

"Anyway, let's just grab the 'benefits' that are in front of us first."

Looking at the vague figure in the bathroom ahead, Chihaya Aine already had her plan in mind -

……ten minutes later……

"Brother, are you ready?"
