====================================

This work is an audio work of binaural recording in its entirety.
All sound, including sound effects and environmental sounds, are recorded with binaural microphones.

In addition, reverb effect is added to the studio-recorded audio to add a sense of atmosphere.
There is a sense of occlusion in the audio created by studio recording, and
The reverb effect is effective in eliminating the sense of entrapment that studio recording creates, as well as the difference between the sound effects (as if they were recorded in a separate space).
It sounds more realistic than a normal binaural piece.

Also, this work does not come with a “SE-free folder". You can find it at
Please understand.

– A Sexual Month with My Solid Sister Continued

This is a continuation of “A month of sexual intercourse with the sister of a firm man".
This is a continuation of “A Month in the Life of a Young Woman".
This is the story of a man who finally crosses the line after that. ……

This is the story of a young woman who is in love with her younger sister, Yui.
The story is about a man who is in love with a woman, but he can’t see it.

As she was being sexually treated, the way she looked at her sister began to change.

I’m sure you’ll be able to understand what I mean.

The obsession with stereotaxia

The direction and position from which sound can be heard is called “localization".
All the sounds in this work are localized as they are in the situation.
For a blowjob, the localization is right below, and for a snuggle or ear lick, right beside.
If you’re a cowgirl, you can place the microphone facing the ceiling and position it diagonally down.
If you are in normal position, place an obstacle behind you and record under the fixed position.
If you want to record a scene with the other side facing you, such as a back scene, you can do that as well.

In the normal position, there is a lot of movement during the scene, including nipple sucking and kissing.
In the normal position, there are various movements during the scene, such as nipple sucking and kissing, and the positioning and distance are adjusted accordingly.

Attention to sound effects and environmental sounds.

We change the location of sound and sound effect recording depending on the situation.
We also change the tuning of the sound effects.

—In the cuddle scene…
When the voice is close to the ear, the head becomes an obstacle and the environmental sound changes. It changes the way you hear from left to right.
When the tip of the tongue is inserted into the ear hole, environmental sounds and sound effects are blocked and can only be heard from one ear.
The crackling when you blink or the sound of your eyelashes rubbing against the pillow.
The feeling of co-sleeping should be greatly enhanced.

—in the production scene
The sound of the pillows rubbing in conjunction with Yui’s shaking her head reluctantly.

In the event that you’ve got a lot of time, you’ll be able to take a look at a few of the best ways to get the most out of your time.
The sound of the pillow and bed sheets rubbing against each other as my body swayed from the thrusting of my hips.

Sometimes Yui squeezes the pillow and shows her attitude not only with her voice but also with her movements.

During play, we suck on nipples, kiss, and stare at each other from a distance.
During play, they suck on nipples, kiss, and stare at each other from a distance, and depending on the position, the voice as well as the sound effects can be distanced or localized.
It’s a great way to make your characters feel more comfortable.

By making it more like reality, the immersion will be greatly enhanced.

Points of interest

The selling point of this film is the “kissing scene".
This is a sound effect that applies bone conduction used in toothpaste sound effects.
Does your tongue feel like it’s swirling around in your mouth? Maybe.

– A sound effect that uses bone conduction.

This is a video that focuses on the everyday life of a young woman with a younger sister, Yui, who is familiar with the “Solid Younger Sister" series.

What do just normal, close siblings usually do in their everyday lives?
Please enjoy such an unremarkable scene.

◆The “cooking part" with emphasis on ASMR

We help Yui, who can also cook properly.
The voice and sound effects are recorded using binaural microphones.
The sound effects are recorded at close range for ASMR.
Cutting onions, cracking eggs, cooking meat, etc.

Leisurely “playing part" ◆

There is no particular development, and we play dominoes and chess in a casual way.
There is little chit-chat, and time flows leisurely.

The “ear scratching part" is a standard part of the healing voice.

The actual voice recorded in the form of a kneeling pillow is slightly displaced from the true side in accordance with reality.
If you feel your stomach in the back of your head, the voice will come from slightly behind rather than right beside you.
If you feel your stomach in the front of your head, the voice is from slightly in front of your true side.
Even environmental sounds will sound a little different when they are coming from the ear that is blocked by the thigh.
Even when using Brahma, the sound should be a little different because the ear canal is blocked by Fluffy.
Depending on the scene, the voice and sound effects are changed to make it more realistic.

Special Edition: “Sleep Psychology" with Yui

I borrowed the concept of “sleep" from the origin of the “Solid Younger Sister" series and made it my own.
In this video, you will learn about insomnia and how to fall asleep and stay asleep better from the perspective of sleep science.
What is right and wrong for falling asleep from an academic and medical point of view.
The purpose of this part is “Let’s have Yui teach us and review our lifestyle".
Please note that the purpose of this program is not to provide a sound sleep, but to learn.

Also, as a “sleep ritual" that appears in the book, Yui reads a picture book to you.
This time, the subject is “Princess Wild Rose" from Grimm’s Fairy Tales.
This scene is just reading a book, so this one could be used for restful sleep.

★ Points of interest

The sleep studies that Yui teaches are all built on papers presented at conferences.
Since it’s academically correct.
If you are seriously struggling with insomnia, you can actually refer to this site.

Please do not get caught up in the obsession of having to practice what Yui is saying.
This is a track that you should listen to over and over again to memorize the content and to get the most out of it.
The purpose of this track is for you to listen to it over and over again, memorize the content, and properly understand what leads to insomnia and how to get rid of it.

By the way, the paper I referred to is a bit old, dating back to the 2000s.
現在は新たな定説が生まれてしまっているかもしれないことをPlease understand.

— A Sexual Month with My Solid Sister Continued–

01Waking up to a blowjob(30:54)
In this episode, you’ll learn how to make your own sex toys.
My first oral caress, performed in the light outside, with the words, “You can’t help it. ……

02 Ear Licking Hand Job (46:19)
When you refuse to sleep facing each other.

[Well, it’s easier to get them to do it that way], Yui says, making me aware of it.
Lately I’ve only been caressing her with my mouth, so today I decided to ask her to make me come with a hand job.

I noticed that Yui was creeped out by the voice whispering in her ear, and I felt her mouth open softly …….

03 popsicle job(34:41)
I’m proud of my legs, she says, and I’m uncomfortable with the freshly applied moisturizing cream on my legs.

At first it was just a crushing motion with my thighs.

Halfway through, he started pistoning between the backs of her knees.

It’s as if you’re having sex with my legs," murmured Yui, her face looking lascivious. ……

04Hidden Blowjob (39:36)
Yui is spoiled even though her mom is in the living room.
The scent of shampoo after a bath makes me giddy.
I’m going to ask her to do it in the living room to counter her complaining about inviting me to family gatherings.
She agreed and began to piston her mouth noisily while her mother was in the dining room.

05Extras [Yui Part 1](03:52)
Yui wakes up in the middle of the night.
When she sees that her brother is asleep, she does something that has become a secret habit of hers.

06 Baby Play (58:03)
My cousin Suzu is staying with us today.
The three of us always sleep together in the shape of a river.
I’m sure you’ll be pleased to know that I’m not the only one who’s a bit of a joker.
I’m not going to back down now that he’s made me aware that Suzu is also sleeping next to me.
Even in this situation, Yuui makes fun of the fact that I asked him to do it, and uses words like “dechu machu".

In the event that you’ve got a lot more than one, you’ll be able to get a lot more.

07 bareback – underwear available (34:41)
As usual, he teases her and pushes Yui down in her school uniform.

Smiling wickedly, Yuui got up on her knees and tried to get me in a good mood.

When I saw Yui in her skirt, which was different from her normal clothes, I became conscious of her pants.

I’m going to suggest a bare bottom thigh.

08 Extra [Yui Part 2](11:49)
The previous act.
I think I may have pouted in front of my brother.
A strange feeling that arises, along with mild disgust.
Today, again, I reach for my crotch as my body demands.

09 bare legs – no underwear (24:09)
There’s something wrong with Yuui these days.
He speaks to me with a lack of confidence and is a bit distant.

Today was no different. I usually ask for it, but Yui asked me, “Can I do it? I usually ask her, but today was no different.

The pillow was pressed against my face, and after the audible scraping of my clothes
Yuui, who was only clad in a jacket, looked dimly …… in the darkness.

10 First Time Having Sex (52:22)
Put your thoughts into words and your feelings into action.
What brother would remain silent when he sees his sister in distress?
It is a privilege that only an older brother has the strength to guide a younger sister, no matter how intelligent she may be.

Total — 05:36:26

— A sound effect that uses bone conduction.–

01Cooking [hamburger and apple pie](01:01:56)
I’m going to cook with Yui, who can do the housework like a good person.
I’m going to make [hamburger] and [apple pie].
I used yesterday’s leftover miso soup and had potato salad in the fridge as a side dish.

The sound of the boiling water is strangely reassuring, and the sound of the meat cooking stimulates the appetite.

02Games [Dominoes](04:31)
Dominoes falling with an unmotivated Yuui.
I’m not a fan.

03Yugi [Shogi](17:51)
The brainy Yui wins hands down! I thought that ……?

04Daily life[Ear cleaning](29:47)
This is the first time I’ve seen this video.
But it feels so good to have someone do it to me that I can’t stop.

I can’t stop asking people to do it for me because it feels so much better than doing it myself.

05 Special Episode [Learning with Yui [Sleep Psychology]](30:10)
Difficult conversations are Yuui’s specialty.

“If it’s science-based, I’m your man! I’ll handle the science-based stuff!

Let’s listen to her once in a while.

Total — 02:24:15

There is also a [H-Scene Recollection] folder with only H-Scenes extracted.
This is for people who want to listen to H scenes quickly.

In [H-Scene Reminiscence], one scene is divided into two tracks, <> and <>.

<> is the audio until just before ejaculation.

Just before ejaculation refers to a few lines before the ejaculation scene dialogue.

This division allows you to listen to the ejaculation scene as quickly as possible, without having to move the seek bar.
This division means that if you want to listen to the ejaculation scene as soon as possible, you don’t need to move the seek bar, you just need to touch the [Next] button.
