【Chinjao Musume.】The story of a big family’s wacky situation – the struggles of a sister in place of a mom

[God! You’re not allowed to masturbate in your sister’s underwear!]
[Then wank in my sister’s underwear!] [ha, ha!]

A large family living in a certain apartment complex.

My sister, who is a female student, is taking care of her six younger brothers and her father in place of her mother who is not here…but she has one problem these days.

It’s a problem with my younger brothers and sisters. However, it’s not a food 'wank’…

One night, she couldn’t stand to see her brothers fighting over her sister’s pants, so she gave them a substitute for her brother’s erotic book, saying, “We used to take a bath together not long ago.

In the event that you’ve got a little bit of time, you may want to take a look at a few of these.

When the other brothers found out about this, they started to gather around her and use her as their “wanker".

Eventually, her father found out, but…

This is a story from a slightly nostalgic time when there were no convenient tools such as cell phones and it was difficult to get a nightly wank.

This is a collection of CGs in which the red-headed sister of a large family is made into a sex worker for everyone in the family.

[eldest daughter: Kyoko Osugi].
An older sister with six younger brothers.
She is a hard-working female student who takes over for her mother in running the household.

She is pretty and has a good figure, but she is a virgin, probably because she is too busy with her family to have a girlfriend.
She is strong-willed and scary when she gets angry, but she can’t always refuse her brother’s requests and is easily influenced.

One night, my younger brothers, who are at the age of masturbation…

The three idiots, the third, fourth, and fifth sons, were found fighting over their sister’s underwear.

I’m going to scold them severely, but my brothers begged me and I accepted to be a [pornographic book substitute].

Since then, the demands of the younger brothers have escalated…?

[Eldest Son: Kazuo Osugi]
He uses his sister as a wanker.
He is a club boy with a lot of energy. He has the biggest dick of all his siblings.
I was horny every day at the sight of my sister, who was almost as old as I was, defenseless.

[Second son: Kenji Osugi]
He uses his sister as a wanker.
He’s a bit popular, but he’s too busy with club activities to have a girlfriend.
He’s a bit of a jerk, but he’s also kind enough to let his younger brother have his turn at using his sister.

[third son: Saburo Osugi].
He uses his sister as a wanker.
One of the three idiots. He’s a cocky, sissy, masturbating little monkey.
He’s a bit of a jerk, but he’s got a great sense of humor.

[Fourth son: Shiro Osugi].
He uses his sister as a wanker.
One of the three idiots. He and Goro are twins.
He loves boobs.

[fifth son: Goro Osugi].
He uses his sister as a wanker.
One of the three idiots. He and Shiro are twins.
He’s a bit of a sexual deviant.

[6th son: Mutsuki Osugi].
He is the youngest son and loves his sister like a mother, and she loves him the most.
But lately, her brothers have been taking turns sneaking into her bed at night…

Like wanking off your favorite big sister.

This is a light NTR if you read it from the point of view of the sixth son.
If you are not a fan of this story, please don’t get emotionally involved with Rokuo.

[father: Maruo Osugi]
The mainstay of the family.
A man with thick sperm who has given his wife seven children.
He couldn’t use his daughter as a bait, so he spent all his money on backdoor videos, encores, and teleclasses…

This is the story of a large family of one woman and seven men who are a little too close.
