Hybrid x Heart Magias Academy Ataraxia

Battleship Ataraxia safely retreated from Thanatoss world. There was nothing they could say except it was fortunate that Thanatos didnt pursue. The cause of that was unclear, whether it was from Nayutas conversation or possibly the main cannon of Ataraxia, but at any rate the rescue mission was a success.

The rescued students were inserted into new organization and orientation for them was taking place in each place where they were assigned to.

Currently battleship Ataraxia was heading to Odins world, but it was estimated that it would take a few weeks until they arrived. Valtantis force in Oldium that Grace was leading had gone ahead to Odin world, they should be going ahead with investigation there.

Odinif we are only talking about battle ability then she might rival Thanatoswe have to link up with them even for a second faster

Nayuta was lying down slovenly on the lounge suite sofa inside Reiris room.

Reiri who was working on her work desk stopped her hand.

Then what are we going to do? Against Thanatos, both you and Kizuna using his Corruption Armament couldnt even make a dent on her right?

Thats so isnt it

Nayuta replied listlessly looking totally exhausted.

Reiri lifted her face and stared at the figure of her mother lying down face up on the sofa that could be used by three people.

Whats the matter? You are being awfully docile.

Yesperhaps this is because of summer heat.

Reiri frowned looking dubious.

Since Nayuta became god and turned into this little girl form, she often spoke joke and made fun of Reiri and others. Perhaps this time was also like that.

But even while thinking so, Reiri was feeling an atmosphere that was different from usual from her.

No! If so then what. There is no need at all for me to be considerate to this woman.

Dont slack off and think up some method to prevail. You intentionally went to meet Thanatos. You got some kind of information from that right?

I mostly understand about Thanatos now butif I reach out my hand to her offering counseling service, I will only get bitten. A child in that age is really difficult isnt it.

You really say that shamelessly huh. The way you are talking feels like you actually have experience in raising child.

With that their dialogue cut off.

But neither Reiri nor Nayuta exited the room.

Reiri was working on her work silently, Nayuta was lying down listlessly on the sofa.

Nayuta took out something from her chest looking as though it was troublesome to even lift her hand. Still facing up, she reached out her hand and put something on the table. The sound of that action made Reiri lifted up her face.

?

Reiri stared at the metallic capsule put on the table with a suspicious face.

Nayutas frail voice could be heard.

This is the trump card to crush Odin.

The reached out hand looked as though it was trying to lift something heavy while returning on top of Nayutas chest.

The shine of the object put on the table made Reiri stood up.

Is thatHeart Hybrid Gears core?

Yesa core that I made from zero for the first time.

What?

The core of Heart Hybrid Gear was originally OOPart of Atlantis world. It was still not understood whether it was the product of super ancient civilization of that world or an instigation from one of the Deus ex Machina.

Even when Nayuta was researching Heart Hybrid Gear, it was nothing more than reusing the already existing core. What Nayuta did was only making so that humans life energy could be used to power up the core in replacement of magic power.

Reiri walked toward the table opened her eyes wide in amazement at that metal piece.

Different from other core, it was emitting a really beautiful radiance. It wasnt an unrefined metal, it had glossy white surface. Blue light was shining from there. It even looked like a high class artistic handicraft.

I seeso you mean to throw in new battle potential.

That core is my greatest masterpiece. Even when compared to other core, I believe there is none that can surpass it.

Reiri gulped audibly.

If she was able to assert that much, then it must really have a powerful spec. The problem was how much ability it specifically possessed and who would use it.

But, it has one limitation.

Reiri clicked her tongue and made a disagreeable face.

As I thought there is somethingso, just what kind of harassment it has?

Nayuta answered with closed eyes.

Reiri, that core is exclusive for you.

!?

Her mouth opened wide unconsciously and stiffened up.

It will be mostly useless even if other person install it. It was made with Reiris biological information as the premise, a core that is adjusted to match Reiris trait. Most likely it is the first order made core in history.

Myexclusive?

Nayuta opened her eyes thinly.

In the first place I only have little remaining power, so its the end with this. Whats this? Is this what they called bedridden senior citizen I wonder.

She made a dry smile with the face of a kindergartener.

Reiri couldnt reply anything to that joke.

Silent time was continuing for a while, before long Nayuta spoke with small volume.

This is a present for you.

!?

Cold sweat trickled on Reiris cheek. Her trembling fingertips picked up the beautiful core placed on the table.

This is the first timeI receive something from you I think.

Nayuta was looking up to Reiri with a thin smile still pasted on her face.

Reiri puckered up her face while lifting the core to the rooms lighting.

Moreover you got no sense. Just where you can find in the world a parent that will give weapon as present. Besides, using this is just like a death sentence.

Nayuta smiled happily.

But you want it right?

-!

That was truth.

The guilty feeling of making her subordinate fought. She even saw in her dream, just how great it would be if she could fight herself.

The problemthe one with the highest aptitude for magic armor in this ship is you Reiri. Making the greatest player using the greatest tool. Its actually also a logical and rational decision.

Mehuh

Besidesif there is Kizuna then you wont die. Even if you install it, its fine if you use it only to protect yourself. If you have that, then you can become god or demon you know? Even if for example everyone else died, perhaps you and Kizuna will be able to survive.

Whasaying screwed up thing like

Reiri swallowed back the words she was about to say.

There was a doubt that she had been feeling since long ago.

But she couldnt bring herself to ask it, speaking out loud that question itself was unforgivable.

However,

For some reason,

She wanted to voice that doubt very much so.

You

Reiri stared at the core that was created for her sake. Its surface, had really detailed and cute decoration applied there.

Perhaps, that was a completely unnecessary decoration.

She shaved her life even if just slightly for something like this?

Yousince you turned into that form

The question lurking inside her heart, was naturally rushing out from Reiris mouth.

Human heart and emotion, were born inside you werent it?

However Nayuta only squinted her eyes and smiled.

In an indoor sports ground inside battleship Ataraxia. In that space that was as big as a gymnasium, there was a giant block stacked up. It was an object that was like four normal Love Room being connected. It was placed at the center of the sports ground. Around it there were measuring instruments, machineries used for all kind of adjustment, external cooling unit, battery, and so on. All those were placed surrounding the box with wiring extending in between.

Kei took out her keyboard and began inputting text.

This is the experimental device of the new Love Room. Its official name is not yet fixed. Codename Chronos.

So big.

It was really contrastive with the portable Love Room used the other day. Kizuna thought if it would be possible to transport this if it was this big.

The development concept of this is greatly different from the portable Love Room used in actual combat the other day. This is still an experimental unit, but from the beginning its also not assumed that it will be used by moving it around. Chronos is being developed by only prioritizing adding the required function.

Required function?

Keis glasses shined.

The power to surpass time.

Eh?

Kizuna doubted his ear.

The function to change the bodys external appearance that was in the middle of research from before. The implementation of that was completed.

Before this, is it what I heard when I did Climax Hybrid with Valdy

However what use it would have after this far?

Kizuna raised his eyes at the system of giant Love Room that didnt exist until now.

So a system this big is necessary for that functionbut, it got completed really quickly isnt it?

Kizuna thought that if it was with this, then perhaps there would be no need for him to dress as girl in front of everyone like before. Thinking that, his feeling became somewhat resentful.

Professor Nayutas power.

Eh? Aa, now that you mentioned it, Kaa-san wrote the program or something.

Its impossible to develop it with this speed if its me. In addition, it doesnt mean that this is using gods miracle. Professor Nayuta carried out the development work really normally, just like how human would do it. And then Love Room that can even be called as ultimate was completed.

Kizuna once more stared fixedly at the toweringly gigantic Love Room.

Is this, reallysomething that amazing?

Inside this is a world that transcended reality. Things that is practically cannot be done, impossible thing, thing that cannot happen, can all occur. You wont understand whether its dream or reality, or whether that reality really occur or not. What is inside this is different from reality, its a different world.

Kizuna was unable to understand the specific mechanism and significance regarding this Love Room. But, he was at least able to understand that developing this was difficult.

I already understood from before, but with this I was made to realize once more my difference with a genius.

Even Shikina-san is also genius enough.

Kei shook her head left and right.

I was called as prodigy since I was a child buteven a genius is just an ordinary person when they passed twenty, thats something that is often said. In the first place its a problem of what I was compared at.

The face of Kei who was always expressionless changed to look like it was brooding somewhere in it.

From the beginning I understood that there is existence that my hand cannot reach. But, I saw a dream, that if I worked hard, perhaps I will be able to get closer even for a little. But, a dream is a dream. I believe that its fine if just do my own researchbut, when it was thrust in front of me that such person exist in this world, I thought, is there any meaning in anything that I do.

Kizuna only knew the figure of Kei who was always advancing development dispassionately. And then he arbitrarily though of her as an owner of terrifyingly tough mental strength from that image. Due to that Kizuna could only be bewildered when she suddenly showed him her weak figure.

Such thingall this time its thanks to Shikina-san that we

Kizuna, you are here already.

The door of the sports ground opened and Reiri came in. An attach case that was shining silver was dangling from her hand.

Nee-chanthats?

Reiri lifted the attach case on her hand and showed it to him.

Yeah. Its a new core.

The thick door of Love Room opened along with the sound of vapor getting jetted out.

Reiri, the preparation is finished already.

Got it. Lets go Kizuna.

Ye, yeah.

Kizuna followed behind Reiri and entered inside the Love Room. Then behind them the door closed with heavy sound.

The insideis unexpectedly normal.

Even though the outside appearance was large, the space inside wasnt that different.

Yeah. The frames largeness isnt for more space, but for the sake of the added function.

For the sake of a function that change the external appearance is itbut, what Shikina-san said, bout the power the surpass time, what does she mean by that?

Reiri manipulated the control on the wall while answering.

This is what it meant.

When Reiris finger pushed the confirmation button, Kizunas field of vision became riddled with noise. And then he was assaulted with a sensation that was similar with dizziness.

It was a severe sensation even more than the usual Love Room. His whole body was paralyzed and the sensation of his body became diluted. He was attacked by anxiousness as though his body was going somewhere far.

What? What happened with me?

His hand reached out to rely on something. His hand was groping around like a drowning man desperately trying to get a hold of something.

Kizuna.

He heard such calling voice.

It was a voice that really reassured him. A voice that made him believed unconditionally that he could trust this person.

When his hand reached out to the direction of that voice, something warm and soft was welcoming his hand. He was embraced with two hands and his face was buried into something elastic with a thickness of a futon.

That sensation granted instinctual sense of security to Kizuna.

How is it? Has your awareness turn clear?

It seemed that Kizuna was closing his eyes without him noticing it. When he opened his eyes just like he was told, his was being buried into a sailor uniformed chest.

Eh?

He remembered that design of collar and ribbon. And then above all this aroma. Amidst the mix of soap smell and sweet aroma, he could faintly smell an adult fragrance that was like perfume, it was a fragrance that he loved and made his chest rumbled.

Nee-chan?

When he pulled away his face and looked up, there was the smiling face of his big sister there.

However he felt something out of place with that face.

It was unmistakably Reiri. However, he felt like her face was somewhat returned younger. She had adult face and figure since in the past, so there wasnt any large difference. If he was forced to say, then perhaps it was because of this sailor uniforms fault?

A collar with blue and yellow line added with green colored ribbon. That breast was pushed up from below forcefully that the navel was visible. Below was a blue pleated skirt.

If I remember right this is Nee-chans high school uniform. At that time I was elementary student. My height is just around this area!?

Kizuna looked down on his own figure in panic.

He was wearing T-shirt and short pants. Excessively unreliable thickness and length could be felt from legs. And then the floor was near.

No way-!

When he looked around the room, a familiar and also nostalgic sight was surrounding Kizuna. It was the living room that Kizuna lived at when he was a child. The sofa, television, and also the table were all just like in the past.

However, the room felt really vast. The height of the ceiling and door, the size of every single furniture, they all made him felt for real that his body had become small.

This place isour house at megafloat Tokyo.

Correct. How nostalgic.

Come to think of itwhen I first entered Love Room, it was this room that was shown for demonstration

Reiri responded looking a bit embarrassed.

Aa, I couldnt think of any other sample that time.

Kizuna stared once more at the figure of his big sister wearing sailor uniform.

What she said about surpassing timeit means this?

Everything is for the sake of this objective.

Reiris eyes moved toward the attach case placed on the table.

Install the core into me here. It seemsthis will, provoke myexcitement, and immoral feelingthe most.

The more Reiris speech was nearing the end, the smaller and more subdued her voice became. Reiris cheeks turned red in shame and she averted her eyes while murmuring.

This is for the sake of obtaining the strongest spec. Im reluctant but this cannot be helped. You toomust be, feeling complicated but, if you can do itwithout feeling its detestable, that, Ill feel happy.

Those words felt like they were said from far away.

I, Im not thinking it detestablethere is no way, Im thinking that.

His tongue couldnt form word well. The beating of his heart couldnt slow down since some time ago. His cheeks were burning, even himself understood how blood was rising to his head. Kizuna was feeling an excitement that he had never tasted until now.

Reiri suddenly directed her eyes to Kizuna and made a bit surprised face.

It seems, that you have become in the mood for it huh.

Eh? Waah!

There was a large tent on the front of his pants.

Kizuna, come over here.

Reiri smiled and turned around to the washroom with the fringe of her skirt fluttering. Kizuna honestly followed behind her. The washroom doubled as the changing room. There was the bathroom at the other side of the blurry glass.

It has been a long time since we entered together.

Ye, yeah.

Reiri opened the fastener at the side and took off her sailor uniforms upper clothes without hesitation. And then she pulled down her skirt and was left in only her underwear. Her white underwear without any decoration was something that Reiri at that time often wore. That underwear that Kizuna sometimes happened to catch sight of was something that made his heart beating fast.

When she took off that underwear too, Reiris splendid body appeared in front of Kizuna. Her large breast protruded out like rocket and it was shaking in front of Kizuna. Her body was returning to when she was in her high school period which might cause it to become more or less smaller. However perhaps because Kizuna himself also became small, it instead looked even bigger.

Whats the matter? Cant you undress by yourself?

N, no. Im fine here.

He replied so, but Reiri gripped the fringe of his T-shirt and pulled it up. Kizuna also obediently lifted both his hands straight up and let himself got undressed. And then Reiri unbuttoned his short pants before pulling it down until his ankle in one go.

Reiri then put her hands on the last piece of clothing and pulled it down gently. When the briefs was lowered until the thigh, Kizunas thing leaped out energetically from inside.

Reiri chuckled when she saw its appearance.

Looks like it got turned into child form properly.

Kizunas face got even redder.

UWAAAAA! Even though its fine even if this kind of place doesnt get returned too!

However it was only its size that was close to the present. That barely let Kizuna retained his dignity. Reiri looked fondly at such Kizuna.

Then, lets enter.

yes.

Reiri took Kizunas hand and they entered the bathroom. And then she turned on the hot water from the shower and adjusted the temperature while bathing under it.

Yosh, its fine now Kizuna.

Next she showered Kizuna. The pleasantness of the hot water, and the strange reality of him entering bath just with big sister made him felt like his thought circuit was getting screwy.

Certainly there was time when they entered bath together when he was a child. However the implication in this current situation was completely different. Right now they were entering bath together with the objective of doing install to his big sister.

When he thought that, Kizunas thing twitched by itself. Reiri gulped seeing that.

Reiris heart throbbing became violent.

She helplessly wanted to touch it.

She gulped her saliva unconsciously.

Thats right. As expected I have to take the lead as the big sister.

She resolved herself so and reached out her hand at Kizunas groin.

This place, has to be washed to.

Uaaah! Ne, Nee-chan-

Reiris hand touched Kizunas thing. Her slender fingers were gently holding it and moved up and down.

Uh! Ku

Nndoes it hurt?

N, noits not that but, that, the tip is still covered

Reiri made an understanding face and kneeled in front of Kizuna. And then, she licked Kizunas tip briefly with her tongue.

Kizuna felt like electricity was running through his tailbone until his head.

Ne, Nee-chan.

If something is not done to this, it will be a hindrance in the install. Because, Im the adult Ill do it sodont worry.

She smiled at Kizuna reassuringly and then held that tip into her mouth.

-aaaa!

Reiri licked around inside her mouth to swell it up. And then she seized the root by making a ring with her fingers and she gently rocked back and forth.

Aah, Ne-Nee-chan-!

Kizuna could do nothing except writhing from the intense pleasure. Stimulation was attacking mercilessly from the part that was more sensitive than usual. Shudders were running through his spine.

Reiri inserted her tongue at the gap behind the skin, she was making that part getting accustomed while slightly adding strength on her fingers. Reiri was gradually making the tip of Kizuna that was hiding to show its face.

And then in one moment, the stuck part got smoothly surmounted.

tsu! Aaaah!

Kizunas waist trembled. Strength entered his feet and his toes stretched tensed.

And the n Kizuna exploded into Reiris mouth the pleasure that was equal with his first climax.

-!

Reiri made a surprised face for a moment, but her eyes squinted and her throat gulped without her mouth letting go.

She was gulping down the first climax that her little brother once felt. A temptation that surpassed her guilt ruled over her heart. And then the affection inside her heart was overflowing.

When Kizuna settled down, Reiri pulled her mouth away slowly. And then she looked up at Kizuna with a mischievous smile.

You came already? I was surprised because it was too sudden you know.

However Reiris cheeks were also blushing from excitement. And then she slowly traced her lips with her finger.

Be, because, it was different from usual, it was amazing

Reiri smiled gently at Kizuna who was making excuse, then she stood up and sat astride the bathtub.

Kizuna, you soak into the bath too.

Reiri lowered her waist into the hot water and then she stretched her legs inside the bathtub.

Kizuna entered between her legs and lowered himself down. He stretched his legs inside the hot water so Reiri could embrace him from behind. The temperature of the hot water was just right, it softened the excitement from before. However his big sisters breast with its amazing elasticity was on his back.

He couldnt calm down with that.

Haait feels good isnt it, Kizuna.

Ye, yes

Dont be that reserved. Its fine if you leaned closer.

Isis that so? Then

Kizuna timidly let his body fell back and snuggled close on Reiris breast. It was soft, and yet despite that it was pushing back on his body, really like a cushion. Even while he was feeling light guilt of leaning on this important thing of his sister, he was still enjoying to his heart content that sensation.

During that time, Reiris hands embraced Kizuna tightly, before caressing his arms and chest lovingly. And then her hands moved from the inside of his thigh toward between his legs. She grasped as though to reward him for releasing his desire just now and then she stroked.

AaaNeNee-chaan

The little brother writhed inside the big sisters arms without being able to escape. That figure made it impossible for the upsurge of Reiris heart to stop.

Aa, how cute, Kizuna.

Her soul was intoxicated with that enjoyment.

Kizunas tiptoes stretched and his body floated from feeling it too much. It resulted with Kizunas thing peeking out in a bouncing way from the hot water.

You did great Kizuna. Its already big.

If Nee-chan, playing with it like thatof course it will get big.

Reiri felt like something pierced her chest.

I, I see.however, it got properly peeled down and turned out good looking you know.

Eh? Really?

Kizuna looked across his shoulder at Reiri with a glad-looking face.

Yeah, if its like thisit looks like, youll be able to install splendidly into me.

Hearing that, Kizuna spoke to Reiri with a serious face.

Nee-chanIll, work hard.

Fufu, Ill look forward to it

Reiri patted Kizunas head and gently gripped Kizunas thing that showed its face from the hot water. And then she kindly stroke up and down.

Do, dont do that.if you do that, ah-!

White splash rushed out from Kizunas tip without any time to stop. That thing which flew energetically impacted Reiris face as though it had taken a careful aim before.

Nh!?

Aaa, so, sorry! Tha, thats why I said dont

Reirir reached out her fingers to the thing that launched the white liquid with an expression that seemed to want to say good grief.

Sheeshlooks like this guys skill in sharpshooting is extraordinary huh.

Her fingers lightly flicked while saying that.

Sorry, Nee-chanNee-chans hand felt good, that I couldnt endure

Reiris cheeks loosened seeing her little brother that was looking up at her apologetically.

Wewell, it cant be helpedlets get out for now. We are going to wash our body properly with soap next.

Reiri took Kizunas hand and they rose from the bathtub toward the washing place.

Like that they rubbed each others body with bubbly sponge and washed each other. They then warmed their body once more in the bathtub before climbing out, and then they dried out each others body with bathtub.

Then lets go.

Reiri presented her hand and Kizuna grasped that hand. Without even wrapping towel on their body, they returned to the living room where they first came at with their hands connected and their body completely naked.

A mirror that was in the bright living room was reflecting the figure of the two. A big sister and little brother that were holding hand to hand naked. Different from in the bathroom, their figure standing without wearing any clothes in a bright room where they were normally carrying on their daily life was unreal, it was really indecent.

That immoral scene excited the two of them whether they wanted it or not.

We, we aredoing something amazing, arent we.

Ye, yeahthis really cannot be shown to other people at all.

The throat of the two made gulping sound. Their cheeks heated and their breathing was also somehow rough.

Kizunashould we rest a little? You have come twice after all.

Kizuna shook his head in panic.

No, nope. Im completely, fine.

When she peered into between Kizunas legs once more, indeed it seemed to be fine.

So your preparation is all ok alreadyKizuna is amazing huh.

Reiri smiled and gently stroked Kizunas head. Kizuna was naturally smiling from getting praised and feeling the pleasantness on his head.

And then, Kizuna also slowly reached out his hand toward Reiri.

Nn-

Kizunas small fingers parted through the bush that was the same color with her hair and crawled into the soft valley. However Reiri didnt make any resistance or even showed a reluctant face, she accepted Kizunas hand quietly. When Kizunas small finger touched the important spot, feverish sigh leaked out from Reiris mouth.

Haaan

Something hot dripped on Kizunas fingertip, and a string was stretched when his hand was pulled away.

It seems Nee-chanalso finish preparing.

Reiri nodded bashfully. However her eyes were shining with lewd expectation.

If its preparation to accept you thenits finished since long time ago.

Reiri took the attach case on the table into her hand, then she pulled Kizunas hand and exited into a corridor.

Lets go to my room.

Invited by Reiri, his feet stepped toward his sisters room. The occasion where he entered her room even when they were living together could be counted. The room felt like a place that he couldnt really enter. Kizuna himself didnt understand if it was because of his reservation toward his sister, or because he was conscious of her as female, or else if it was because he felt that room was like a holy ground that he couldnt violate due to his great respect to his sister. But, there was no mistake that it was a place that he couldnt enter lightly.

The two of them entered that room, in order to install into his big sister. As though this place was truly a forbidden land.

Reiri lowered her waist on the bed and opened the attach case. And then she took out a core that had completely changed shape from the inside and handed it over to Kizuna.

This isNee-chans exclusive

I, if you said it like that, when its in this shape

Reiri averted her eyes with blushing cheeks.

Aa

Kizunas face also spontaneously turned red. What he said sounded like he was saying that his thing was for Reiris exclusive use.

Reiri laid down on the bed and put her head on the pillow.

Reiri called at Kizuna who was standing still without any idea of what to do.

Kizuna

Kizuna nodded, guessing her intention.

yes

Even though he had entered his sisters room before, as expected he had never slept on the bed. The permission to climb that bed was given to him. Kizuna put his knee on the bed reservedly.

Bu, but, where should I go, or rather, what kind of posture I should make?

Kizuna was perplexed as though all his experiences until now had gone somewhere. Kizunas head was pure white from the excessive nervousness and excitement. Reiri lifted her knees and opened her groin as though to help such Kizuna.

Aa

Kizuna was relieved and he advanced between Reiris legs, and then he put the core on Reiris important place.

Nn

Reiris body shivered.

Nee-chan, is it really okay?

Reiri smiled to reassure Kizuna.

Of course. Please be quickKizunas

Ne, Nee-chan-!

Kizuna slowly pushed in the core.

Fuh! Aa, nnAaAAAAAAAAH!

Reiris body bent like a bow. The core didnt hurt her body, it only gave her pleasure. Reiri was bewildered with this thing that invaded into her for the first time, and then it felt like her consciousness would be blown away by pleasure that exceeded her imagination.

And then Kizuna also felt the same.

Aah, unbelievable! Ri, right now Im, inside Nee-chan-!?

It felt like his head was going strange with excitement that he experienced for the first time and terrific pleasure. And then the limit of pleasure that was filling him up mercilessly.

Thi, this is, Nee-chansinside-!?

Kuh!?

He gritted his teeth trying to desperately endure.

However his resistance easily crumbled very quickly.

Ah!?

Reiri felt the same heat from inside and above her stomach. She felt the weight of liquid splashing on her cleavage until her stomach.

And then she felt energy of magic power bursting inside her stomach, spreading out gradually. At the same time the thing that was asserting its presence before was getting smaller as though it was withering.

Ki, Kizuna? Already?

-!?

Kizuna turned bright red until his ears and then he desperately made excuse.

I, it shouldnt be like this! U, usually it would go longer! E, eh? Just why its like this. Shit-! Something like this, this is just strange. Its wrong, this is

Reiri faced Kizuna and opened both her arms toward him. And then she whispered with a gentle voice.

Its fine, just calm down. Now, come here.

yes

Kizuna kept the core inserted and let his body fell on top of Reiri. Then, her breast came just right in front of his face.

Here. Breast.

Eh? Bu, but, thats a bit

Its like Im a child fawning on my mother.

He felt like his image of making Reiri felt the best sensation and carrying out the best install was rapidly getting away from him.

Its fine, just suck.

yes

Kizuna crawled his tongue on the jiggling breast of Reiri.

Nhaa

Reiris mouth leaked out a faint voice. Kizuna who felt better hearing that voice put the tip into his mouth.

Ah, nnfuu

Doing that caused a sweet fragrance to fill his mouth. When he flicked that hard protrusion with his tongue, it immediately increased in size. Kizuna became engrossed in sucking Reiris breast.

Reiri gently caressed the head of Kizuna who was being like that.

Nha, haanhhow is it? Youve calmed down?

Yesthank you, Nee-chan.

After that Reiri suddenly showed a smile.

Want to rest a bit? You must be tired after consecutively coming from some time ago. Rushing is

Reiri felt the thing inside her stomach gradually recovering its hardness and size. She lifted her head in a bit of shock where Kizuna was scratching his head looking a bit shy.

Lo, looks likeIm fine.

Reiri let out a chuckle seeing such Kizuna.

It seems so. Good grief, youre bottomlessAaHAAAaNH!

Kizuna began pulling in and out the core, taking her by surprise.

Ki-KizunaAA-! So-, so suddenly-, ahn AAH

Ne-, Nee-chan, this time, this time for sure-, Ill make you feel good-!

Yo, you idiot! ThatsaAAAANH It, it feels go-, go-, gooood already from the beginningaAAAAAAYAAAN

For Reiri, this pleasure was also something that she experienced for the first time. That violent pleasure made her consciousness getting far away. She gripped the sheet and desperately held on to her consciousness. If she didnt do that, she felt like her body would fly away somewhere.

The figure of her young little brother desperately moving above her was reflected on her teary eyes. Her whole body was filled with euphoria as though her dream had been granted, it became tears that overflowed out.

Ne, Nee-chan?

She shook her head at Kizuna who was calling to her worriedly. After confirming that joyful smile, Kizuna rubbed the inside wall so that his big sister could feel it even more.

Hah! YAaAAAAAAAAAAANNN-, the, there- AAA!

Electric current was running through her whole body from her stomach. Her lower body was paralyzed and couldnt move. It felt like she had turned into an object that existed only to accept Kizuna and obtained pleasure.

Each time the core with the same shape of Kizunas thing entered her body, pleasure that made her wanted to shriek rushed through her. And then when it was pulled back, tremendous pleasant feeling that felt unreal knocked down her mind.

Reiri let her tears and drool flowed out and she drowned into wave of pleasure. It felt like all the memory of why she was doing this or even what she was currently doing had been blown away.

Both of them were swallowed and toyed by stormy wave of ecstasy and intoxication.

The core tormenting Reiri was also granting terrific pleasure to Kizuna himself. The pleasantness he felt was nearly a torture for his thing that only started its debut with his transformed body. The melting honey pot was sucking in Kizunas thing, the soft wall was constricting it like a silk floss.

No matter how desperately he endured, it was arbitrarily wanting to explode.

No good! It has to be simultaneous with Nee-chan for the install!

Kizuna gritted his teeth and endured the pleasure jolting his body.

Faint blue light was emerging from Reiris body.

A bit more! Its just a little longer!

AAH! Kizuna-, KIZUNaAA

However the limit suddenly arrived.

AAH!?

Pleasure and affection surged out from Kizunas thing. His body was ejecting regardless of his will.

Fuah!? Ki-, Kizuna-!? YA-A-AAAAAAAAAAAAAANNN-

Something was released into Reiris body. It was particle of warm magic power. It was too thick, which made the inside of Reiris womb to feel its mass. Inside her body, it felt like particle of magic power was striking her most important place. That pleasure was hard to describe with written or spoken words.

Reiri thought that the nerves of her brain were going to burst. She was already just a step before the limit. However, for the sake of obtaining the strongest magic armor, even further height was necessary.

That person.

That woman,

She gave me something for the first time, for my sake.

And then it is something that should become a hope for all people.

Guh!

Just now Kizuna came earlier.

However right now magic power and life force were surging inside her body, it was as though a nuclear fusion was happening inside, she was feeling a tremendous energy swirling into vortex.

That was what they had raised through the process until now. Even if they done the same thing one more time, there was no guarantee that she would be able to obtain the same amount of energy.

Besides what they were doing this time was what she was wishing for the most, the situation where it could be anticipated that the highest energy would be obtainable. Such situation couldnt occur twice. She could be the most excited and obtained the most pleasure only once at the first time.

There is no way, this power can be let go here!

Reiri gritted her teeth.

However, can this upsurge be maintained while waiting for Kizunas recovery?

But, there is no other way than to do it.

Ki, Kizunawa, wait, rest for a bit

N, no, Nee-chan, not yet!

Reiri opened her eyes wide.

Ki, Kizuna?

The movement of the core didnt stop, rather it was starting to push and pull with even more fierceness.

Hih! NooOOOOOOOOOOYAaaAAAAAAAH!

A scream reflexively surged out from Reiris throat.

Ki-, Kizunaaa, aaah, AAAANNNNNNNNN!

It had only ejected life force just now. In spite of that, it was repeatedly stabbing over and over deeper inside.

Yo, you-, di, didnt, you just come-!?

Kizuna also understood. If they calmed down for the moment before returning from the start once more, they wouldnt be able to obtain this feeling of exaltation anymore.

This was their first and last chance.

Ill continue like this! Because

Kizuna gritted the back of his teeth.

This is something that Kaa-san created for Nee-chans sake!

-!?

She finally, finally!

Kizuna.

Aaan!

Particle of magic power struck the inside of her body once more.

Hih!? Ih! IiIIIIIaAAAAAAAAH!

Even so Kizuna continued to move. It was as though the magic power that the core was spurting out was coating over Reiris body.

Y-, yo, AAaaA! E, even though youre, co, comi- AAAAAAAA!

Ill absolutely make it a success! With Kaa-san, Nee-chan, and me!

Kizuna-!!

Electric current was shorting up continuously in Reiris brain. Light was flickering before her eyes. She was already not comprehending what was that or what was going on. However, even so Reiri yelled.

KIZUNAaA-! COME, HOWEVER MANY TIMES ILL RECEIVE, EVERYTHIING

NEE-CHAAANNNNNN-!!

Kizuna fell on Reiris body and sucked on her lips. Reiri also accepted Kizunas lips as though she was waiting for it. And then the tongues of the two entangled with each other.

It was as though they turned into one living thing. Their instinct pleaded, wishing for all the spots that could be connected to join each other, as though to fusion their body into one.

And then the core reached the deepest place inside Reiri, and Reiris inside also stuck at the cores tip.

At that moment, the greatest magic power was sent inside Reiris body.

Magic power beads in vast amount violently drive in pleasure and climax inside Reiris body.

Reiri was welcoming climaxes in every single moment, she tasted a climax to the degree that it felt like her mind would break.

It was a heaven that was like hell.

It was a pleasure to the degree that if it was average person their sanity would definitely be lost and their mind crashed.

Murderous pleasure pierced the two.

Heart shaped light emerged in Reiris eyes.

And then, magic power that was impossible to measure burst from the body of the two.

That power destroyed even the Love Room, blowing away the wall and the ceiling into unrecognizable shape.

Reiri!?

Shockwave assaulted Kei outside who was glaring at the gauge while holding her breath.

Sent flying by the shockwave, Kei struck the wall. When she lifted her face, Keis eyes opened wide from the shock and she stiffened.

ReRei, ri?

What she saw at the center of the sports ground, was the wreckage of Love Room.

And then burning fragments and smoke.

No way

Kei was staring dumbfounded at that wreckage.
