Actually, the moment Kasugano Sora spoke, Hoshino Miru had already sensed something was wrong.
Kasugano Sora sat sideways on his lap. Originally with her shoulder blocking, Hoshino Miru could at most just embrace her soft waist, but she actively hugged his arm, her budding little bunny softly pressing against it. It wasn't the kind of fullness that could be exaggerated as engulfing, but the slightly swelling softness still had a wonderful sensation.
Due to the lack of undergarments, this unique touch let Hoshino Miru fully feel that the girl's developing body already possessed an irresistible charm.
She grabbed Hoshino Miru's arm, making him touch her small belly. Her two tender legs rested on Hoshino Miru's thighs like this. As the girl shrank into Hoshino Miru's embrace, her perky little bottom also restlessly twisted a few times, making Hoshino Miru instinctively want to hold her body down.
However, Kasugano Sora hugged his arm even more tightly, making it impossible for Hoshino Miru to pull his hand away. Instead, because of this movement, it rubbed against places it shouldn't touch.
Hoshino Miru's breathing immediately became somewhat rapid. As a hot-blooded young man, regardless of whether Kasugano Sora's actions were intentional or unintentional, he still couldn't control his body's hormones.
"Brother's palm is so big..." Kasugano Sora leaned in Hoshino Miru's arms, her small face flushed, the heat from her breathing seeming able to blow onto Hoshino Miru's ear. "It seems... to have touched again uu..."
Hoshino Miru's right hand had been touching her small belly. Actually, this place was somewhat dangerous - girls wouldn't let people casually touch here, because going slightly lower would reach face-reddening places.
"Wait a minute, what are you two doing!" From the other end of the phone came Eriri's furious voice. She had obviously heard Kasugano Sora's gasping sounds too.
Hoshino Miru came to his senses and barely suppressed this restlessness. While explaining the situation to Eriri, he used his eyes to signal Kasugano Sora not to play pranks.
Kasugano Sora blinked and continued grabbing Hoshino Miru's arm, gently twisting her body in his embrace, her faintly burning cheeks leaning on Hoshino Miru's shoulder, deliberately making sounds that only girls would make when aroused.
Eriri was about to explode. Hoshino Miru felt he was about to explode too.
He knew the girl in his arms was attached to him. They often had intimate contact normally, but such direct teasing was still somewhat unbearable.
Hoshino Miru didn't speak and just hung up the phone.
At first, Kasugano Sora thought her prank had succeeded, but feeling something pressing against her little bottom, she finally reacted, her pretty face turning completely red, motionless.
"Can you get down now?" Hoshino Miru exhaled deeply. Right now their bodies were pressed too intimately - any slight movement would greatly provoke bodily desires.
Kasugano Sora became particularly embarrassed and said very quietly to Hoshino Miru: "You have a reaction."
She didn't get down, still clinging to Hoshino Miru's embrace, her body soft and hot. Whether it was her small belly or her slender waist, the feel was extremely soft and smooth. This sensation was too comfortable.
"Can't I have a reaction?" Hoshino Miru forced himself to calm down. "You're also a cute and pretty girl now. Don't casually keep moving around in a boy's arms."
A normal girl would immediately distance herself from Hoshino Miru at this time, but Kasugano Sora didn't run away - just her small face was flushed.
"But Miru didn't used to react to me." Kasugano Sora was very shy, but her eyes were more sparkling, like a child who got a gold star, particularly proud.
Because you didn't make such strange sounds before. Just sitting quietly versus panting while twisting your body were two different things. No man could withstand the latter.
"Can you get down now?" Hoshino Miru felt somewhat awkward. He didn't dare make big movements now, or he wouldn't be able to control himself.
"Wait!" Kasugano Sora suddenly remembered something. She excitedly snatched away Hoshino Miru's phone.
Hoshino Miru didn't know what she was doing. He saw Kasugano Sora fiddle with it for a bit, then raise the phone with a brilliant smile, making a victory sign at the camera, then taking advantage of Hoshino Miru's inattention, suddenly turning her head to kiss him.
Click—
Hoshino Miru was caught off guard and could only watch helplessly as Kasugano Sora sent the selfie just taken to Eriri.
"Mm-hmm, this way Eriri won't suspect anything." Kasugano Sora closed the phone with particular satisfaction.
Kasugano Sora was a very cunning girl. She clearly knew Eriri was anxious now. If left alone, the other party would immediately call back and keep calling until the situation was clear.
Therefore, Kasugano Sora decisively struck first.
In Eriri's eyes, this selfie was purely provoking her - it would be impossible to imagine Hoshino Miru was pressing against Kasugano Sora's little bottom underneath.
This way, Eriri would only hold this grievance, planning to fiercely retaliate next time, but wouldn't continue disturbing their current time together.
Kasugano Sora put down the phone. She looked at Hoshino Miru, and the courage she had mustered immediately lowered her head again due to the girl's instinctive shyness.
"Want to do naughty things?" Kasugano Sora squirmed. "I know boys can't help it. If Miru wants to release, I don't mind."
Just as Hoshino Miru would have a reaction to her body, actually the girl would also have strange reactions because of it. After all, being pressed against continuously, the girl would also restlessly become aroused.
This was a very normal physiological reaction. Moreover, Kasugano Sora already had skilled experience. Smelling Hoshino Miru's scent, her heart beat faster, her legs vaguely rubbing together.
She knew what saying these words meant, but what did it matter? She had already done bolder things long ago.
Hoshino Miru really couldn't hold back. The girl looked too lewd right now. Without even making any provocative movements, just these words alone could make one lose control.
"Do you know what 'naughty things' means?" Hoshino Miru touched her small belly. It would be very easy to reach under her clothes.
Kasugano Sora blushed, her small belly becoming warm from his touch, and said quietly: "Of course I know. Don't think I'm still a child!"
Actually, she had already become a bad child, doing bad things to Hoshino Miru every day.
"I know Sora isn't a child now, but after doing it, Sora might regret it." Hoshino Miru's rationality hadn't completely collapsed. His palm only stayed on the girl's lower abdomen.
"Why would I regret it?" Kasugano Sora grabbed Hoshino Miru's clothes, her eyes sparkling, as if telling a secret treasured for a long time. "I like Miru, and I know Miru likes me very much too."
Hoshino Miru regretted it. He knew that once he had a reaction, the girl would fiercely throw fastballs.
Kasugano Sora wasn't afraid of him at all. Rather, she was more afraid he wasn't interested in her, which was why he had never dared use [Sensitivity] on Kasugano Sora.
Chapter 35: Naughty Things Feel Good
Hoshino Miru couldn't control this instinctive reaction. It was normal for Kasugano Sora to seize this opportunity.
However, before cohabiting, Hoshino Miru had already prepared himself mentally.
"No, there will be a child." Hoshino Miru gently warned Kasugano Sora. Right now they had absolutely no protective measures.
Kasugano Sora was stunned. She hadn't expected Hoshino Miru's reason for refusing would be so proper.
"Just finish outside at the end." Kasugano Sora also spoke quietly, her face carrying an excited flush.
"As a girl, can't you be a little shy?" Hoshino Miru felt parched, though he had been trying his best to restrain his desires, but she was too proactive.
"Because Miru immediately talks about children and such, of course I'm being shy!" Kasugano Sora hummed with dissatisfaction. "Even with protective measures, I wouldn't do it."
"Why?" Hoshino Miru was stunned.
"We don't have a blood relation - why wear one?" Kasugano Sora said quietly. "Plus I wouldn't mind having a child."
"Having a child this early, your parents will break my legs." Hoshino Miru couldn't help but complain.
Kasugano Sora finally thought of her parents and seemed like she should worry about it a bit, making her embarrassedly turn her pretty face.
However, that Hoshino Miru could consider this actually made Kasugano Sora quite happy, showing he cared about her.
"Can you get down now?" Hoshino Miru was still enduring his body's impulse. Once a reaction appeared, it was hard to disappear on its own in a short time, especially with Kasugano Sora still sitting in his arms.
Kasugano Sora had wanted to nod, but her eyes suddenly became very sharp.
"No, you're fooling me."
"What am I fooling you about?"
"Every time you plan to deceive someone, you become particularly serious."
Seeing Hoshino Miru's dumbfounded expression, Kasugano Sora slightly lifted her chin, somewhat smug.
Now she had caught Hoshino Miru's weakness - why should she be so obedient?
Sisters occasionally had to be bad children too, otherwise they'd always be played with by their brother.
"Since Miru is very worried about this, it's fine." Kasugano Sora wrapped both hands around Hoshino Miru's neck, her voice full of temptation. "It's not like we can only do that kind of naughty thing. There are many naughty things that can make Miru comfortable."
The fragrance from her breath was very alluring. Hoshino Miru felt the restlessness in his body getting worse. Plus she was too close - it seemed he could slowly lean over to touch the girl's small nose, kiss the girl's moist lips.
Kasugano Sora seemed to know something too. Her eyes carried vague expectation as she slowly closed them, waiting for the boy's kiss.
Soon, Kasugano Sora felt her cheek was somewhat cool. Something soft and carrying heat touched her.
Kasugano Sora opened her eyes and glared at Hoshino Miru indignantly. He had just kissed her cheek - she had been expecting a mouth kiss!
"You're right, there really are more comfortable naughty things." But Hoshino Miru pressed against her cheek, as if biting her ear, gently blowing hot air. "But I don't think Sora can handle it."
Kasugano Sora's face turned completely red. The familiar breath made her somewhat dazed. Hoshino Miru's palm that had been embracing her slender waist naturally fell between the girl's hip line and thighs, feeling the round little bottom wrapped in hot pants, and the smoothness of the skin between her thighs.
Girls this age already understood many naughty things. Stimulation from the opposite sex to the body would also make girls produce strange reactions. Just slightly touching sensitive places made the girl's heart beat particularly hard.
Just gently stroking a few times, Kasugano Sora immediately made whimpering sounds, instinctively tightening her legs. It wasn't simply that she couldn't handle such stimulation, but that her body arbitrarily recalled self-entertainment experiences. Girls with experience would become even more dewy at this time, almost unable to resist this feeling.
Hoshino Miru didn't do anything. He embraced the girl's soft waist while his other hand reached under the girl's clothes, touching the soft small belly. This warm feeling would also make the girl unable to handle it.
"Miru..." Kasugano Sora suddenly gripped Hoshino Miru's clothes tightly, her soft body beginning to tremble violently, her voice revealing a sobbing tone.
After the trembling, Kasugano Sora kept her face buried in Hoshino Miru's embrace. Even through clothes, he could feel her face burning intensely.
Hoshino Miru was initially somewhat surprised, then a smile appeared. He leaned over and quietly asked: "Did the naughty thing feel good?"
"Uu... bullying me again..." Actually Kasugano Sora was quite thin-skinned. She knew why she had such a strong reaction - after all, she often snuck into Hoshino Miru's bed.
Now being actually played with by the person himself, it was naturally more comfortable and stimulating than self-entertainment.
Hoshino Miru laughed. The initiative had returned to him.
"Sora, I like you." Hoshino Miru restrained his smile, his expression very serious. "Actually I can't wait to do comfortable naughty things with Sora. Seeing such a super cute girl dangling before my eyes every day, saying I'm not moved would definitely be lying."
Kasugano Sora was stunned. Just as her fierce fastball had overloaded Hoshino Miru's brain, this fastball from him also left her at a loss.
Realizing this was a confession, Kasugano Sora instead felt shy, while indignantly looking at Hoshino Miru. Not saying it earlier but waiting until after the girl finished - what a pervert.
"But not now." Hoshino Miru pressed his forehead against hers, as if this would make her understand. "We're too young. It's not time yet."
Kasugano Sora first looked at Hoshino Miru incredulously, then pouted.
"Can't you accept siblings?" Kasugano Sora felt somewhat dejected. "From now on, I won't call you brother anymore."
"It has nothing to do with that. You can keep calling me that if you want." Hoshino Miru shook his head. "I just think the feelings between us don't need to be proven by doing something."
Kasugano Sora thought about it - it seemed true. She wasn't a shameless girl with her mind full of wanting to do naughty things with boys.
Just earlier, discovering Hoshino Miru had a reaction to her was too exciting, making her get excited too, with a feeling of finally catching him.
Now being able to hear Hoshino Miru admit he liked her and also had desire for her, Kasugano Sora was already very satisfied.
Their feelings were already very good. Upgrading from fake siblings to real lovers wouldn't change anything. Kasugano Sora felt her parents would agree to this too.
After all, they were already cohabiting. Doing naughty things and such - there was no rush at all.
Kasugano Sora accepted this reason.
But—
This reason was too proper, so proper it was super suspicious!
Kasugano Sora understood Hoshino Miru well. The more serious this guy was, the more he was diverting attention!
In this instant, the girl's little brain spun rapidly, then images of Eriri and others flashed through, her eyes widening.
"Are you really planning to have a harem!"
Hoshino Miru nearly bit his own tongue. It seemed he really couldn't hide anything from this sister.
