There are nine ぼしかん episodes so far and several related oneshots
But several of them weren't on e-hentai so I decided to complement existing ones and their english script done by me.

------------------------
On my 24th birthday.... for me who happened to be at the parent's home, my mother held a small birthday party.
My father went to a business trip, but mother bought some alcohol saying it's a special occasion. So I suggested her to drink it together.

Ee? Alcohol?
I can't handle alcohol very well...... then... only a little bit...
------------------------
01-02
------------------------
Then I realized that she really can't handle alcohol only after she almost stripped her clothes.
As I was also drunk, I immediately jumped at her without thinking when she invited me with spreading her legs.

You're staring at me too much<3
Shall we do it?
------------------------
01-03
------------------------
Drunk mother became enthusiastic and took me to her and father's bedroom. And I came inside her many times.
After three shots, she seemed to have come to herself. But she continued pretending to be drunk. So she and I had sex until the next morning.

Huhuh... Does it feel good?
You can cum more<3
....Happy birthday to you<3

Welcome back~~~!

When it becomes really unbearable to me, I text mother before I return to home. Then she changes into pampering mode and welcomes me.
And her being naked means that [we can have sex anytime]
-------------------------
08-02
-------------------------
But, first of all, I ask her to embrace me.

Thanks for the hard work~ You are very tired, aren't you? Today, I'll pamper you with all my might

My always sleeping mother becomes extreamly supportive in times like this...... Mother's breast is very soft.
-------------------------
08-03
-------------------------
Wait for a bit. I'll prepare these for you.
Hora, you can put it between my boobs<3 Or do you want to put it inside me?
-------------------------
08-04
-------------------------
If I make this slippery with my saliva, you'll feel great won't you?
If you want to come, you can come on my boobs anytime.
-------------------------

Aah...<3
Huhuh.............You came a lot<3 Good boy. Good boy<3
-------------------------
08-06
-------------------------
My mother's boobs make me feel comfortable......

You~~ Even if you became big, you are still a big baby<3
Even if you are sucking them that much, milk doesn't come out of the breast~~ ....Are you going to sleep, already?
-------------------------
08-07
-------------------------
Aah...
-------------------------
08-08
-------------------------
This has also become big.
Have you become feeling refreshed yet?
-------------------------
08-09
-------------------------
For a long time, whenever she pampered me, we had sex. So if she pampers me now, my dick gets erect soon.

Good boy, Good boy<3 Your mom's hands feel good, don't they? Today, you're more of a baby than usual<3
-------------------------

-------------------------
08-12
-------------------------
It's a rare occasion that she put my dick inside her while she is doing cow girl.
Aaah.....Can you feel that it's inside?
In the past, your penis was half as tall as this~~<3
-------------------------
08-13
-------------------------
Unn<3

Hi, welcome back<3 Hora, shall we hold our hands together?

Profile

Age: 42 y.o

Mom-son incest history: 12 years

Her boobs are huge and she is also tall (178cm)

She has been living only with her son for 15 years.

When her son wants to be pampered, she pampers.

How it started: When her son was young, there was an incident that made her son depressed. While she pampering her, her son ejeculated. From then, for the sake of sex education, they did various things together. Then they started having sex. For the last ten years, their sexual relationship has continued.

Because it was for the sake of sex education, she is good at hand job. Recently she has become being able to deepthroat him. (When he was young, she could do it but after his dick became larger she couldn't fully swallow his dick. So she tried her best)

Her favorite sex act is cow girl but because she is large, that makes her tired easily. So they usually have sex in missionary position or doggy style.

The ring she wears was bought her by her son with his first paycheck.
