"Hey sis what's the matter?", Riruru asked in a confused voice while following behind Rio who suddenly appeared outside her class after recess.
Without explaining anything Rio just dragged her out, trying to quickly leave the school.
"It's nothing....it's nothing....let's just go home early ok"
"But why? I was going to play with my friends today!"
"Riruru just listen to me!"
Hearing Rio's angry voice Riruru pouted her lips in dissatisfaction but didn't continue to question her sister.
Because even she felt that something wasn't right with her today.
After getting a good look at her Riruru suddenly noticed her slightly red eyes.
"Sis we're you crying?", Riruru exclaimed in surprise, using her hand she quickly grabbed Rio's shoulders looking straight into her eyes.
Seeing her sister's questioning face, Rio's expression trembled a little before she said in a pleading voice.
"Riruru let's leave first alright? I'll explain later....."
"If you say so...."
Sensing that the severity of the situation was higher than what she initially expected, Riruru quietly followed behind Rio.
In no time the two sisters managed to arrive at the school gate.
But just when Rio was about heave a sight if relief.
"Hey, Rio!"
A familiar voice that sent shivers down her spine entered her ears followed by a hand that quietly rested on her shoulder.
Turning her head saw Kazuo standing right beside her with his hand around her shoulders.
"Ho is this you're sister?", Kazuo narrowed his eyes on Riruru, his gaze scanning her body from head to toe.
"Hello I'm Rio's friend!", Kazuo suddenly extended his free hand towards Riruru's direction.
"Oh! Hello, I'm Riruru!", Riruru who didn't know the situation also raised her hand and performed a handshake with Kazuo.
Meanwhile, Kazuo's hand which was resting on Rio's shoulder has quite extended into her dress through her collar.
Rio's eyes moisten up feeling Kazuo's finger moving along her upper breast, She wanted to take a step back but Kazuo's hand held her tightly in place.
"Hey, are the two of you going home? How about we send you guys off?"
Suddenly three more men and two women appeared behind Kazuo with weird smiles on their faces.
"Sis....", Even Riruru started feeling that something wasn't right so she turned towards her sister only to see Rio's lowered head and her body trembling from time to time.
"Sis let's go back I forgot to bring my notebook!", Riruru quickly grabbed Rio's hand and pulled her making Kazuo let go of Rio.
"Yes....yes...l-lets get you're stuff.....", Rio said in a quick voice as if grabbing a sudden straw of hope.
The two sisters quickly started making their way back.
"Rio make sure to hurry up! We'll be waiting for you here!"
Kazuo waved toward the retreating Rio and Riruru with a friendly smile on his face.
Although his tone was friendly, his words only made Rio feel a terrible sense of fear as her breathing became quicker and she suddenly grabbed her shoulders as if trying to find a sense of comfort.
"Sis! Sis! Are you alright? Hey, calm down! Here have some water!"
Taking in a deep breath, Rio quickly remembered that she wasn't alone, She Aldo had a sister to take care of.
"Let's go let's go to the teacher....."
Rio and Riruru quickly made their way towards the teacher's ward.
"What you're saying you want me to drop you home?", The homeroom teacher asked in an annoyed voice while looking at the two sisters.
Hearing his words, Rio simply nodded her head.
"Tsk you know it's my last day at work and yet you're giving me extra trouble.....", The fat homeroom teacher's voice became lower and lower the more he looked at Rio and Riruru.
The corners of his mouth raised up seeing their chest and slim waist.
"Well, it's not impossible..."
A bad thought appeared in the Homeroom teacher's mind as he slowly stood up from his chair.
At the same time, red sirens started going off in Rio's mind who was currently feeling extremely sensitive to other's gaze.
For some reason, the look that the Homeroom teacher was giving her seemed oddly similar to Kazuo.
"W-well just go on our own.", Rio quickly pulled Riruru and walked out of the staffroom.
"Wait! You----"
Ignoring the teacher's voice Rio and Riruru quickly left the place and entered the girl's washroom.
After shutting the door to the washroom, Rio felt a little sense of comfort.
But then the reality of the situation hit her.
'Now what do I do...'
She couldn't leave on her own and the teacher wasn't helpful either.
'Mom? Should I call Mom? Or elder sister Ririna?'
'B-but they won't be able to help wither...much worse they might get dragged into this mess as well....'
The more she thought the more desperate Rio felt.
Suddenly the scene from before filled her mind, the sensation of Kazuo's hand moving around her body made her feel weak as the figure faltered.
If not for Riruru quickly supporting her, Rio might have ended up falling.
"Hey sis...", With worry clearly present in her eyes Riruru said.
"How about we call Hiroya?"
"Hiro?..."
Suddenly a light bulb light up inside Rio's mind.
Yes.
Why didn't she think of calling Hiro?
'But will he be helpful?...'
Rio thought with a doubtful look on her face.
It's because even now Hiroya's image in her heart was that of a weak little brother who needed protection.
After all Hiroya's change was too sudden and because of Hiroya not leaving his room for three continuous days, She didn't have many opportunities to interact with him.
'No Hiro might end up hurt if he comes....'
While she was busy organizing her thoughts Riruru had already called Hiroya.
"Hello! Brother! Come and pick us up! What you're sleeping? Who cares about your sleep? You better come quickly...fck he hung up on me!", Riruru cursed in a loud voice and called again.
But this time just before the call was about to connect, Rio took the phone from her.
"Have you gone crazy?", Hiroya's annoyed voice came from the other side of the phone.
For a moment Rio stayed silent, calming down she tried to speak in a normal voice.
"....can you please come?...sniff. Hiro..."
Midway through her sentence, Rio ended up crying a little, but as to not worry her brother she quickly threw the phone back to Riruru.
"H-hey! What was that? Don't suddenly throw the phone at me! Y-yes! Brother! Give the phone back to Rio? Ah, she went to the bathroom! Crying? No no, she wasn't crying! Something just went inside her eyes that's all!"
Riruru tried her best to calm down the situation.
"You're coming? Ok! Make sure to hurry up!"
Riruru heaved a sigh of relief after ending the call.
Then she turned her head and looked at Rio who was leaning against the wall, doing her best to wipe the tears which kept falling out.
"Sis.....", Seeing her sister's condition, Riruru felt sad, moving towards her she gently hugged the trembling Rio.
"I-I e-ended up dragging you and H-Hiro into this mess!"
"It's alright sis! Don't cry!."
Riruru didn't know what was happening but she still tried her best to comfort Rio.
------------------
"Are they in trouble....?", Hiroya thought as he got up from his bed and quickly wore his shirt.
At first, he thought Riruru was messing with him but hearing Rio's breaking voice, Hiroya concluded that something must have gone wrong.
So he quickly got ready and left the house.
"Hiroya where are you going?"
"I'll come back in a minute."
Replying to his mother, Hiroya left the house.
He hasn't forgotten that he was inside a hentai world.
Plus his family were the main characters of that hentai.
-------------------
Rio and Riruru exited the washroom and entered an empty classroom through which they were able to clearly see the main door of their school.
"Is Hiro here?", Rio asked in a low voice while lying face down on the desk.
Riruru looked out the window and shook her head.
"Sis it's been less than 10 minutes how can he arrive so earl-----Wow he's really here!"
Rio quickly got up from her seat after hearing Riruru's excited words.
Seeing the familiar figure quickly making its way through the empty school grounds and coming towards their building, Rio couldn't help but feel a little relieved.
"Let's go down."
"Ok!"
After running all the way, Hiroya felt it deeply, the need to buy a vehicle.
'I'm still 14 so I can't drive...'
Scratching his neck in annoyance he wondered if he could get away with driving a bike considering that he doesn't look anything like a 14-year-old.
'Well where could they be.....', Hiroya frowned as he entered the deserted school building.
'Even if the school has ended how come there are no guards or anything?', Hiroya wondered in confusion while taking out his phone to call his sisters.
"Hiroya!"
Hearing the familiar voice he put his phone down and turned towards the stairs.
'Well she seems okay.', Hiroya thought while looking at Riruru quickly making her way toward him.
But then his gaze landed on Rio, making him frown.
"Brother you came so quickly!"
Ignoring the brat, Hiroya went towards Rio.
"Hey don't ignore me!"
"Are you alright?", Hiroya asked while carefully looking at Rio who kept avoiding his gaze.
"I'm okay Hiro....let's leave quickly....", Rio said in a quiet voice.
'Yeah right.', Hiroya almost wanted to roll his eyes at her poor acting, he really wanted to call her out but seeing that she didn't seem to be in the correct state of mind he decided to take her back first.
"Let's go!"
Hiroya turned around while gesturing g at them to follow.
"Hey Hiroya how did you arrive so quickly? Did you take a cab?", Riruru asked as she walked on his right side.
Meanwhile, Rio quietly took his left side.
"Cab? No, I ran.", Hiroya replied casually.
"What! Don't lie to me!"
"I'm not lying to you."
"Boo! Hiroya is a liar."
While Hiroya was getting a little annoyed at Riruru's mischief, he felt someone hug his left arm.
Moving his head he saw Sister Rio who was walking a little distance away suddenly attached herself to his arm.
'It's them! It's Kazuo!', Rio's eyes shook in fear as she looked ahead.
Kazuo and his group were standing there casually chatting with each other.
The closer they got to Kazuo's group the more Rio's feeling of fear grew.
And unknowingly she started pressing her body against Hiroya's arm using all her strength as if trying to use him as a shield.
His arm was pressed tightly between the two bulges in her chest while her hand held tightly onto his hand.
The closer they got the faster her heartbeat became.
'It will be alright....it will be alright.....', Rio prayed desperately in her mind.
Then as if her prayers were heard by God, they managed to easily pass Kazuo's group without any problem.
'Nothing happened?'
Everything went so smoothly she couldn't help but think that she was dreaming.
But after she arrived at her house's door she finally concluded that it wasn't a dream.
'We really made it?', Rio thought with a dull look on her face as she entered her house.
---------------------
"Hey, Kazuo why did you just let them go?", A round-faced minion among Kazuo's group asked.
But even after waiting for some time he didn't get a reply from Kazuo who kept staring at the way Hiroya and his sisters left.
"Kazuo don't tell me that guy scared you?", Another minion said in a joking tone making everyone laugh.
Everyone but Kazuo.
'What is this....'
Kazuo thought.
'This inexplicable feeling of oppression.....'
There was a reason he didn't attack Hiroya and his sister.
It's because he felt something strange from Hiroya.
'Just is was that guy.'
Kazuo frowned, then turned around and suddenly punched the guy in the face who joked about him being scared.
Seeing the sudden turn of events Kazuo's group stopped laughing at once.
"K-Kazuo w-why did you hit me?"
Instead of a reply, all he got was a kick from Kazuo which sent him rolling back and hitting the wall falling unconscious.
"Ah shit I also ended up letting that mute go.", Kazuo said in annoyance.
Then his gaze turned towards the two girls in his group making them flinch.
"Well, we still have you two don't we?"
"K-Kazuo what do you mean?"
The girls suddenly took a step back seeing Kazuo leisurely coming towards them.
Then under their stunned gaze, Kazuo placed one hand on one of their shoulder and his other hand on the other one's waist.
"K-Kazuo-----mhm"
One of the girls tried to protest in a small voice but stopped mid-sentence when Kazuo's hand suddenly lifted her skirt and pulled her panties up making her tighten her hips in response.
"N-no!K-kazuo!", Her face blushed in shame as she tried to pull away from him but couldn't since his arm was wrapped around her waist.
Meanwhile, the girl on Kazuo's other hand didn't even dare to let out a sound as Kazuo's hand slipped inside her collar and started playing with her breasts.
After all the one Kazuo just sent unconscious was her boyfriend.
Seeing his ending, a deep sense of fear enveloped the girl making her give up any thoughts about resisting.
Then suddenly Kazuo let go of her breast and grabbed her collar.
'What is he...'
Just when the girl was wondering about his motive.
Under her horrified gaze, she saw Kazuo slowly pull her shirt down from her collar slowly exposing her breasts for everyone to see.
I'm no time one of her breasts was fully exposed, the pink nipple was grabbed by Kazuo and played around with as he pleased.
"N-no K-kazuo it hurts!"
The other girl couldn't help but cry out in pain as she felt her underwear being stretched too much making her feel pain.
Standing opposite Kazuo the two boys couldn't help but gulp down a mouthful of saliva looking eagerly at the exotic scene.
