「I'll join later. Who goes first?」
「Hey, that's unusual. Aika is going to give it up」
「Look. You know, I'm a little afraid of how it's going to turn out」
In the usual bedroom, everyone in the apartment is present.
Aika is wearing a pretty white bra and panties.
Maria is dressed in black with a collar and a mature negligee.
Riko in a maid's uniform with a choker.
Hana in a simple white camisole and shorts of the same color with a pink collar.
Suzu in a black bra with frills and panties, which she shows off without hesitation.
（When they are all lined up, it's a great view...）
Chisato returns to Chihiro's body and murmurs to him.
Well, that's true, it is not a bad idea to watch the play from an objective point of view while her body is not temporarily exposed, and it seems that Chisato can also enjoy Chihiro's pleasure in this state.
Chisato seems not to be lying about liking girls as well because her voice has an exciting sound to it.
「Haha, I don't think it will turn out to be that crazy...」
[Stimulus Amplification] and [Stimulus Sharing].
Both should have a straightforward effect.
「But I'm still scared. That's why I watch at first」
「Well, then, why don't you just let Izumi-kun decide? I don't mind if I don't participate」
「Okay. Then, I'll choose one of the four except Aika」
While partially ignoring Hana's words, Chihiro nodded his head and thought for a while.
「Okay—Maria, come here」
A black-haired girl with sparkling eyes walks up to Chihiro on the bed.
Instead of being scared, she is delighted to see him, and after she came to him, he embraces her from behind then running his fingers on her body. Of course, he used both of his new abilities.
At the same time as Maria's small voice, Chihiro's body felt a rush of pleasure. It was a slight sensation, like being lightly touched by a feather broom.
「Ah...it's a strange feeling」
The four remaining members of the group felt the same stimulation.
Aika murmurs in behalf of the other members.
And then, Maria moves her head to look up at Chihiro.
「So you can feel my pleasure, too?」
「It seems like it. I wonder if it's possible to not include me... and, yes」
「Mmm, it's a little stronger than before」
This time the sensation did not hit Chihiro as it did before, as he caressed Maria's neck, sides, chest, and stomach.
He felt a few percent more pleasure divided into five equal parts and given to each of the girls.
「Aika, what do you think? Do you like it?」
Maria asks Aika as Chihiro continues to pleasure her.
And even though he rub her breasts a little roughly, she does not show any sign of pain.
「Hyaa... yes, I don't mind it」
「But this is going to be hard to get used to」
Aika's answer was followed by Riko.
It was understandable, since she felt pleasure even though she was not touched. But then, seeing Maria getting blamed like this was convenient for the girls.
Many moans are heard in the room. The pleasure each of them gets is small, but when they pile up, the effect is evident.
「It's so frustrating... Chihiro-sama」
Maria tells Chihiro as she wriggles around.
Although she was being touched, the amount of pleasure was less than usual and it had the effect of rushing her.
In a sense, it was as if the person who was being held was suffering a loss.
And due to this, Chihiro thinks that he has to be a little careful how he uses it.
「Well, let's make it harder...」
He reach inside Maria's negligee and slide his fingers directly into her hairless crotch. Apparently, Maria was not wearing panties.
And while he was caressing her secret parts with enough dampness, he suddenly caught sight of her ears and suddenly, have a thought to prank her. Then—
He kiss her right ear while making a small sound.
Maria suddenly jerked up.
She looked back at Chihiro, but Chihiro extended his tongue without caring.
He licked its surface. It tasted faintly of sweat. The fact that there was no strange taste or smell told him that it had been well taken care of.
「Chihiro, sama.... It's dirty there」
「That's not true. It's okay」
Chihiro smiled back at Maria and traced the surface all over with his tongue.
He looked at Aika and the others and saw that they all had their hands over their right ears. However, they also seemed to have a hard time concentrating on their secret parts since he had not stopped working on the crotch.
And it made him think that they were cute.
As he thought so, he put his tongue in Maria's earhole. He move around slowly and very carefully in the very small space. He performs ear torture, remembering the services he has been given by the girls.
「Maria, don't move, it's not safe」
Maria's face was bright red.
The stimulation itself should not have been too strong, since it was distributed, but the way to stimulate her, which was not usually done to her, seemed to have worked.
And after that, Chihiro continued to stimulate her vagina, clitoris, right ear, then left ear, and so on.
Pant… Pant… Maria panting.
Her face was relaxed as if she was feeling good, and she was at Chihiro's mercy, but she did not show any sign of climaxing.
It seems that the stimulation is not enough for her.
She is in a state of halfway pleasure, unable to come or to rest, and is in a state of being killed alive. This may be a possible way of training, but it is not the purpose of this session.
So, Chihiro decided to take a countermeasure.
「Maria, do you want to come?」
「...Yes, I want to come. Chihiro-sama, please make me come」
Her black eyes honestly conveyed her desire to climax.
「Okay. Then you're going to put it in yourself」
「Ah... Yes, I understand」
And so, with her beautiful face contorted with lust.
She rushed and mounted Chihiro with cowgirl position.
Maria's M nature is on full display in this somewhat perverted act, and she does it without hesitation.
The girls let out a deep breath together as her hips sink down to Chihiro's cock.
And from this point, it turns out to be more interesting than Chihiro thought it would be.
After all, there is a limit to the number of people he can hold at once. He can only hold one girl at a time, and even with full use of his fingers and tongue, he can only hold two or three girls at a time.
And it is true that the more people he has, the less time he can spend for each one of them. There is a limit to how much free time a person can have by sharing the household chores or by making efforts to have as many children as possible.
But [Stimulus sharing] can be an answer to these concerns.
While holding one person, Chihiro can give pleasure to other members.
Although it may be frustrating to only share the pleasure of others, it is much better than nothing at all. In particular, it would be great to be able to relieve the boredom of the waiting time.
「Well then.. Riko, come here」
「Heh? Uh, yeah」
When Maria and Chihiro were connected, he called Riko over.
Chihiro ordered her to mount his face, and she did so, being careful not to disrupt the skirt of her maid's uniform.
If one stimulation is not enough, then just have a few of them at the same time.
Riko's cheeks turned red when she realized what Chihiro was trying to do.
However, she nodded her head.
She carefully takes off her panties, which are surprisingly white, while still wearing her maid's uniform, lifts up her skirt, and straddles Chihiro.
She stopped just before her hairless crotch pressed against Chihiro's mouth.
「Oh, but...Master...can you breathe under this?」
Riko is the only one here who has not undressed.
If she straddles him in the skirt of her maid's uniform, Chihiro's vision is almost completely covered by darkness, which in turn reduces air circulation.
「I'm fine. It's not so bad that I can't breathe」
「Okay. I'll go」
With a gentle move, Riko's crotch rested on Chihiro face, and her skirt softly covered the area around him.
Then, with almost nothing in sight, Chihiro let his senses take over and extended his tongue. Thanks to Riko's fine adjustment of the position of her hips, Chihiro licks her secret parts.
「Ah...this is great」
「As expected of Izumi kun, you have bad taste」
A voice from the gallery speaks up.
When Chihiro wondered what was going on, Maria's voice explained.
「It was like being licked while being penetrated...」
It is a sensation that is not usually possible unless one is in a very acrobatic position.
Aika and the others who were not touched by Chihiro, as well as Maria and Riko, were stimulated unexpectedly on one side, and their bodies were gradually being consumed by the sensation.
（...um, Nii-san. I-I want to feel Maria-san's and Riko's pleasure...）
（Because. It looks so comfortable...）
The voice echoing directly in Chihiro's head sounded extremely shy and at the same time had an atmosphere of lust.
Maria, Suzu, and Chihiro. Since she was born under the influence of such people, it was natural for her to be aggressive in lewd acts.
（Well. But even so, I'm afraid if I share it with you, I'd come right away」
How to do it?
After thinking about it, Chihiro comes up with a way.
（Chisato, can I use [Dominate] on you...?）
（I don't know, but I can try）
Lick Riko's love juice, apply saliva, and stimulate her sensitive spots.
Maria moves her hips rhythmically and Chihiro occasionally thrusts his penis up.
While he continued these blame, he continued the conversation with Chisato in his brain.
Chisato answered in Chihiro mind's voice and became Illusion, making an oath in a live voice.
「I belong to my brother. I swear to serve him from now on until he says I am no longer needed」
Hana and the others sounded surprised.
And as Riko suddenly lifted her hips and rolled up her skirt, Chihiro looked at Chisato.
She was sitting on the floor, exposing her white naked body.
She was completely naked, without a bra, panties, or collar. The only thing that could be called a decoration was a [mark] on her lower abdomen.
As expected, it was a complicated pattern of folded letters of the alphabet - but the shape was different from all the others Chihiro had seen so far.
「...Hahaha. I did it, Nii-san」
「I thought I had to touch it, but I guess Chisato is special」
Chihiro smiled back at her as she said with her cheeks rising.
Chisato, on the other hand, lifts hier right hand and presses it against the engraved spot.
「I can feel it. I can feel Nii-san's thing inside me through Maria-san」
Somewhat embarrassed to say, "Good," Chihiro replied only that.
And with the new naked girl a B or C-cup, well-balanced limb, Maria could feel Chihiro's penis growing harder and bigger.
「It's a natural occurrence, but I'm a little jealous」
Chihiro hear a murmur, and the interrupted movement of Maria's hips resumes.
She clamps his penis tightly against her, moving harder and more exaggeratedly than before the interruption.
And not knowing Maria's situation, Chisato looked at Chihiro's penis engulfed in Maria's lower part of her abdomen with a fiery gaze.
Riko's voice came out, and her crotch was pressed against Chihiro's face again.
Chihiro, giggling inwardly because his mouth was no longer free to move, resumed his torture. He caresses Riko's mellow secret parts mercilessly.
The lewd sound and lewd breath echo in the room.
The more Chihiro tortured Riko and the more Maria moved, the louder and clearer the sounds and voices became.
Riko's lewd smell fills her long skirt, which is pulled down and it filled Chihiro's nose.
On the other hand, Maria's vagina, which had learned Chihiro's shape, was sucking his crotch firmly and giving off strong and intense pleasure.
「I can't take it anymore!」
It's Suzu's voice.
Maria and Riko jumped after a sign of movement.
Suzu started to masturbate uncontrollably, and as a result, Chihiro understood, even without looking, that the pleasure the girls were getting had increased.
The pleasure for three girls was given to six girls including Chisato.
However, it should not be simply half the pleasure. Chihiro's [Stimulus Amplification] and the synergistic effect of the overlap of the different stimuli are also generated.
And then there are the remaining girls.
「...Takatsuki-san, do you want to join us?」
「Eh? Hana-chan... Mmm」
「If you don't like it, just shake it off. I can't take it anymore either」
It seems that Hana pushed Aika down.
Since it was her, she should have been gentle in the play itself, even if she started it by force.
Soon a sound of kissing and sensual breathing of both of them started to be heard.
「Oh, this is too much!? I'm feeling it too much...!」
When all five of the six, except for Chisato who cannot masturbate because of Illusion, begin to indulge in pleasure, the pleasure of each is divided into six equal parts and redistributed.
Estimation, the pleasure is not equal, but rather squared.
If the number of [Dominated] subjects increases and they participate in the play, or if each individual performs more intense play, it will be stronger.
「...ahaha. If this becomes a habit, we'll all be addicted to Nii-san」
Chisato's voice is sweet too.
All of them are aroused to a level where they could climax at any moment, and they continue to act harder and harder in pursuit of that climax.
When it comes to this point, they are all in it together.
As Chihiro thought this, he speeded up the movement of his tongue and penis.
Six charming voices filled the soundproofed room, overlapping each other.
At the same time, Chihiro's vision shook in a white light, and the tip of his penis released a large amount of sperm as if it exploded.
Spurt! Spurttttt! Spurtttttt!
It took several tens of seconds for the ejaculation to completely subside.
「*Pant* *Pant* Chihiro-sama」
「Master, this is too much. This is really making me crazy」
After a while, Maria withdrew her body from Chihiro's penis and rested her body on his left arm.
Riko, who had stopped straddling him, also clutched at his right arm.
「Ah, you two are so sneaky!」
「It's true. Come on, Hana-chan, let's go too」
「Eh, no, I'm...」
Suzu walks unsteadily up to the bed and wraps her arms around Chihiro's right leg.
Aika, on the other hand, presses her body against Chihiro's chest with her cheeks flushed. The remaining Hana also reluctantly touches Chihiro's left leg.
（It felt good, Nii-san）
Chisato, who had disappeared from her phantom body, whispered softly and gently.
With such a pleasant sensation and comfortable tiredness that it was hard to believe that it was only one climax, they all fell asleep.
Yotsuba's H-scene will be shown separately.
