summary

You are the eldest son of the Hishikura family, a prestigious zaibatsu family that has existed since the Meiji era.
He has been trained from an early age to be the next president of a giant corporate group.
Moreover, they are restricted in their behavior according to dozens of family precepts that have been passed down from generation to generation, and they spend their days in a stifling environment.

Your only emotional support is your older half-sister, Sumika.
Junka is the only person you can open your heart to, as she has been taking care of the heir to the throne in place of your mother who died prematurely.
You loved her as a sister and as a woman, who treated you with strictness but always with compassion.
And there was one more special reason for your exceptional admiration for Junka...

"The ejaculation of a legitimate son from the time of his sexual intercourse until he comes of age should be entirely controlled by the woman of the household, without exception."
It is one of the family precepts followed by the Hishikura family to protect the eldest son's seed and prevent conflicts over the family title.
Since this was established, the mother of each generation in the Hishikura family has managed the ejaculation of her eldest son.
Junka, who had taken on this role herself in place of her deceased stepmother, had been regularly performing your sex work ever since she became well-versed in it.
　
That night, as usual, Junka visited you in your bedroom.
The older sister asks as she strips off her kimono, generously revealing the curves of her voluptuous body.

"Would you like to masturbate tonight?"

appeal point

Clerical low tone Oneshota x doting dusky sex life

　The heroine of this work is a tall, muscular body and an older half-sister with a bewitching bass voice!
　She appears to be strict and faithful to the family code, but secretly she loves you, her brother, very much.
　She will take care of your desires in a clerical manner during "Ona-sister" time, but with lewd words and a lot of affection...
　Sometimes strict, sometimes sweet, sometimes lovey-dovey... enjoy an intense sexual processing life with plenty of practicality!
　

A heartwarming, sweet, and innocent love drama about a sister and brother who fill each other's loneliness.

　The touching story of a sister and brother who overcome the conflict of their different statuses and communicate with each other is also an attraction of this work.
　Living in an old family where feudal customs still remain, they share the common loneliness of having been deprived of the love of their parents, and are therefore strongly attracted to each other.
　However, they are unable to honestly communicate their feelings for each other due to their different circumstances: one is a legitimate son who will be the next head of the family, while the other is the son of a concubine.
　The story of their relationship and the heroine's emotional transition makes the H-part more exciting and deeply immersive♪
　The climax of the film, in which the siblings engage in an emotional, lovey-dovey, and bestial lovemaking, is the highlight of the film, and we hope you will experience it with your own ears!
　
The entire recording was done by KU-100, with powerful close bass whispering voices!

　This is a high-quality binaural audio work recorded in a professional studio with a high-end KU-100 microphone.
　The quality of the voice of the heroine "Junko Hishikura," played by Tyrol Oyama, can be fully appreciated.
　Please enjoy the "crotch-tingling" performance of the sultry silent whispering, ear kissing, and low-pitched wanking that echoes in your ear!

track list

Prologue" (03:53)

　One night, as usual, your sister Junka visits you in your bedroom.
　After breaking off the awkward chit-chat, Junka asked you if you would be willing to perform sex work on her.

　Will you masturbate tonight too?
　...Yes, sir. Let's begin preparations immediately.

2. "Will you masturbate tonight?" (30:06)
Approximate timing of ejaculation [27:16].
(Whispering lewd word handjob / ball massage / skin handjob / whispering foreskin peeling / stopping just short of ejaculation / clenching glans / rolling handjob / "pyu-pyu" call during ejaculation / semen drinking)
　
　Junko sits her younger brother on her lap and begins their customary "masturbation" of sexual desire.
　While giving a hand job, he explained in detail how and why ejaculation control was introduced in the Hishikura family,
　Whenever he wanted to ejaculate, he would remind her to apply to him.

　Yes...you can leave everything to me.
　My sister will always be available for your every need.
　I will take care of your penis and all of your precious baby seed.

3. "Please spoil my sister more" (30:04)
Approximate timing of ejaculation [26:14].
(Sweetly cuddling baby play / affectionate kiss on cheek / full affirmation whisper / reward ear kiss / breastfeeding hand job / lullaby finish / "pyu-pyu" call during ejaculation / semen drinking)

　You have been given imperial education at the behest of your father, who is the current head of the family, and you collapse from exhaustion from the numerous lessons you are forced to learn.
　When he woke up at night, he found Junka at his bedside nursing him.
　Junka is worried about her brother and begs him to be more indulgent to her, but when she realizes that you just woke up and have an erection...

　Mommy feels very happy when she gets to spoil her little boy, don't you think?
　Just knowing that the boy needs me makes me happy and makes me want to give him lots of tender loving care.
　So, please put aside your feelings of "embarrassment" and pamper Mommy with all your might.

4. "I will accept your penis folds" (30:07)
Approximate timing of ejaculation [28:18].
(Folded masturbator with a short stop, both hands restrained, short stop continuously while explaining the internal structure, masturbator sex assisted by swinging hips, masturbator made to understand and speak for his feelings, "pyu-pyu" call when ejaculation occurs)
　
　You have been caught masturbating behind your sister's back by browsing a banned adult website.
　A quietly indignant Junka declares that instead of concealing the fact that you have broken the family motto, she will perform a fold for the purpose of re-education.
　Her hands were tied behind her back, and just as she was about to prepare herself to endure the pain that awaited her, her sister returned from her preparations to find an onahole in her hand.
　
　Young master's semen is not something that should be thrown up casually.
　In order for you to fully understand this, the glans is compressed just before ejaculation, and you are asked to continue to hold back.
　We will thoroughly shorten the length of the cock and imprint directly on the young man's seed, the weight of its value, on the cock.

5. "Let's practice pussy sex" (31:42)
Approximate timing of ejaculation [29:13].
(gentle pussy instruction / tongue kissing instruction / female genitalia explanation / penis piston lecture / cowgirl position with erotic manga dialogue read out loud / "pyu-pyu" call during ejaculation / rubber sperm drink)

　As you promised last time, you ask Junko to take care of your sexual desires.
　Junka tells her brother that from this time on, she intends to have him practice sex with her during her ona sister's time.
　She is the one who teaches him how to have sex with his future partner.
　You feel joy at being brushed down by your beloved sister, but at the same time, you feel a growing sense of frustration.

　Note the reddish-black, bloodshot labia minora.
　The clitoris, a small protrusion on top, erects hard like a penis,
　The vulva is repeatedly puckering and contracting, covered with love juice that is constantly overflowing from the secretory glands.
　This is a sign that you are "always ready to accept a penis".

6. "May I truly love you? (25:30)
Approximate timing of ejaculation [24:16].
(Nighttime lovemaking sex / saliva-filled cock cleaning / vacuum blowjob / strong raw penetration / serious courtship portio mating / ovulation confirmed seed press / simultaneous climax with a masturbating voice)

　Unable to control your desire to love Junko as a woman, you sneak into your sister's bedroom and make love to her at night.
　At first, Junko tries to reject his brother's overstepping of his bounds, but his resistance is gradually weakened by the way he continues to whisper his love to her.
　The mixture of joy and hesitation, as well as the unbearable pleasure, causes Junka's feelings to unravel, and she begins to reveal her true feelings, which she has been keeping hidden until now...

　It's not too late, I really can't go back any further...
　Aaaaahhhh! Hhhhhh, hmmm... oh no...!
　Oh, my cervix... no poking my portio... no poking my portio... ......
　I'm going to open...my pussy...I'm going to start preparing to make a baby on my own...!
