Ah, it's so refreshing.

I'm so happy that I have two children and they are growing up healthy.

But recently, there has been a change in their life.

Let's go to the beach this summer with us.

I'm fine.

Why?

I'm not going.

You can't go?

You can't go with us?

I'm not a child like Kazuya.

I'm not going.

Why?

I'm fine.

We've been taking baths together.

Is it because of puberty?

Next, do this.

Natsuma is a good sister to both her and Kazuya.

This is the Yes, I will sign.

Oh, I see.

Do you understand?

Yes, I do.

As a sister, it's good to see her caring about her brother...

but sometimes I feel like she's overdoing it.

Kazuya, you're amazing.

You got good grades in everything.

You even got two perfect scores.

My sister taught me.

You've improved a lot Kazuya.

Continue the good work...

You can do it, Kazuya.

Yeah.

Thank you, Natsuma.

It's nothing.

Thanks for the meal.

Hey, don't leave the tomatoes.

Hey, Kazuya.

Let's review the mistakes we made today.

Yeah.

Let's go.

Hey, Natsuma, wait.

In the summer, she always rebels against me.

She doesn't listen to me.

Only health and fitness?

Why did he get this score?

Kazuya, why did you keep secret?

This technique...

You can do it with other textbooks.

But...

I can't understand it even if I just look at the textbook.

It's the same with other textbooks.

It's okay even if he can't do one textbook.

You don't have to be able to do everything.

No, I have to be able to do everything.

There is no perfect person.

Hey, Kazuya, let's go.

Hey, Natsuma, let's talk.

You don't have to worry about what Mom says.

You can just study hard in other subjects.

But...

I'm sorry.

I'm probably the reason you have bad grades in health and sports.

Why?

I'm not good at health and sports either.

So I can't teach you well.

No, you're not bad.

No.

I have to take care of you.

So it's my fault that you can't get good grades in tests.

Okay.

I want to overcome my weakness and be taught by you.

Here?

It's difficult.

Do you know what this is?

I don't know.

It's a woman's toy.

I've never seen a real one.

I see.

I know.

But, have you ever seen our mother in the bath?

Because...

My sister and mother have a lot of hair.

I see.

Yes.

Can you see it?

I don't know which one is right.

Then...

If I do this, can you see it?

You're wet.

What's this?

What?

Are you peeing?

No, I'm not.

What's wrong?

I think I'm going to have a erection.

Let me see.

Are you okay?

I'm fine.

What should I do?

Are you okay?

What should I do?

What should I do?

I'm scared.

What are you doing, Natsuma?

First, you two have to tell me you know what's going on.

Got it?

He can't see it even if he don't know.

Got it?

But I can't help it.

You have to see it for yourself.

Got it.

I'll tell you everything.

You two, watch me.

You're both motivated.

You have to tell me, okay?

First, here.

It's called clitoris.

When a woman is stimulated here, she gets sexual pleasure.

Clitoris?

Yes. When a woman is stimulated here, she gets sexual pleasure.

It feels good, right?

It's okay to feel good.

And...

The female genitals is called a vagina.

This is called the vagina.

When a male penis enters here...

...and ejaculates, it will go into the uterus.

And the female will be pregnant.

That's how babies are made.

The round part is the end of the large intestine.

The fluttering part inside is the small intestine.

You're feeling better, aren't you?

Natsuma.

It's natural for you to feel better.

It feels good.

You're feeling better now.

It feels good, right?

Yes, you're feeling better.

I feel like I'm fluffy.

Yes, you're feeling good.

You're feeling good.

You don't have to hold back.

You don't have to hold back.

You don't have to hold back.

You're feeling good.

Kazuya, look in the mirror.

Can you see?

This is called an erection.

It's called an erection when the penis gets bigger.

Kazuya, this is called seminal liquid.

Rub it like this and rub your penis.

Rub it hard and you'll get white liquid.

This is called the semen.

Semen?

Yes, semen.

This is called the semen.

Do you understand?

Yes.

That's how you make a baby.

If you have a ejaculation,

a woman

may get pregnant.

I feel so good.

I feel so good.

I feel so good.

I feel so good.

Katsuya, are you glad?

This is good enough, right?

Hey, is there anything you don't understand?

Are you okay?

How was the exam?

My score was better than last time...

because of what mom told me.

Give it back.

Give it back.

You should ask me about studying.

You're my sister.

Right?

That's true, but...

Give it back.

Give it back.

Last time...

I can do it if I look at it once.

It's easy.

Give it to me.

What are you doing?

Give it to me.

What are you doing?

Take it off.

Why?

Let's study.

Study?

Take it off.

Study?

Yes.

Take it off.

Take it off.

Here we go.

Why are you putting on your pants?

Take your hands off.

What?

Take your hands off.

Wait a minute.

Here.

Wait a minute, sis.

Here.

What's wrong?

Put your hands off.

Why?

It's okay.

But does it matter if I put my hands off?

It does.

Why?

I'm going to study with you.

In person?

Yeah.

Um...

I'm sure...

Let's continue...

Here we go.

What are you doing, sis?

I'm doing a backflip.

A backflip?

It's a backflip, right?

Yeah.

Backflip.

See?

I'm doing a backflip.

Oh, really?

Yeah.

I can do it even if I'm on my back.

And...

Um...

Well...

What should I do from here?

I don't know.

Um...

Yeah?

What should I do?

Mom.

What is it, Katsuya?

Hey, what are you two doing?

What do you mean?

We're studying.

I told you the other day.

You have to study with an adult that you know.

What?

Shut up.

But...

it's a study.

That's true.

But do you know why you do this?

I knew it...

I shouldn't teach him half-heartedly.

I should teach him until the end while he's interested.

Listen, what we're going to do now is very new.

Sex is a very fresh thing.

Do you understand?

This is a lesson for making children, like in the textbook.

So don't play with it.

But what should I do?

I'll teach you.

First, as in the textbook,

we have to rub the penis of the Kazuya.

Can you stand up?

I'm sorry.

Thank you.

Does it feel good?

Yes.

Do you want me to suck this?

Yes.

I'm going to put it in my mouth.

It's getting better, right?

Yes.

You're getting bigger and bigger.

It feels good, right?

Yes, it feels good.

I'm getting used to it.

Does it feel good?

Look, it's getting bigger.

Let's do it again.

It's good.

Sit down.

Do you remember what the male penis was and what the female one was?

Well...

I'm sorry.

Did you forget?

I haven't seen it yet.

The female one is called vagina.

Vagina?

Yes.

You remember it now, right?

Yes.

And...

When the male penis is inserted into the vagina...

it's called sex.

Sex...

Yes, it's called sex.

When you have sex, a baby can be born.

A baby can be born.

First, I'm going to spread the vagina.

This is the vagina.

You need to zoom in on it.

Really?

Can you see?

The baby comes out from here.

Isn't it amazing?

The baby sleeps from here.

After having sex, the baby can be born.

The baby is born from here.

Isn't it amazing?

So, if I put my penis in your vagina, We can have a baby.

Yes, we can.

But, it's delicate for women.

If you don't treat it gently, it's hard to insert a penis for men.

So, I'll make a ring with my finger.

I'll insert a penis.

It doesn't fit, does it?

I'll put my finger in.

Do you lick me?

Yes.

You lick me.

You licked me.

I'll put your finger in your hand again.

By licking the female penis,

it becomes easier to put the penis in.

So, by licking the female penis (clitoris)...

it becomes easier to put the male penis in.

There are a lot of them, right?

By doing so, the female penis feels really good.

It feels good.

You licked a lot, right?

Yes.

When the female penis feels good,

it becomes easier to put the male penis in.

Yes.

Do you understand?

Yes, I understand.

There are a lot of things to do to make the female penis wetter and softer.

To make it feel good.

Yes.

I understand.

Then, can you wet my clitoris?

Yes.

Here?

Here?

Lick here.

Like how I licked Kazuya's finger.

Lick my vagina.

Yes, around there.

Yes, be careful.

If you lick too much,

the woman will feel it, so be careful.

From around here,

lick around the nape of the clitoris.

From the side to the top and bottom.

Yes, you're doing great.

Like this?

Yes.

Yes, please lick it more slowly.

It means that it feels good.

Yes, you're doing great.

Yes.

You're licking the sides and the bottom.

You're doing great.

It feels good.

You're doing great.

Yes.

If you do it carefully,

the woman will feel it.

Very much.

Yes.

You're doing great.

You're doing great.

You're doing great.

Kazuya, if you lick the top of the head,

I'll feel your tongue.

Kazuya, you're doing great.

OK.

That's how you lick it.

Stand up.

Be careful!

Okay.

Wow!

Now I can teach Kazuyai.

Kazuya, you're still okay, right?

Lay down here.

What are you going to do?

I'm going to get on top of you.

Kazuya, I'm going to put your penis in your mom's vagina.

Kazuya, just relax.

Where are you going to put it in?

Kazuya, look at this.

I'm going to put your penis in your mom's vagina.

Your penis is going to go deep inside your mom.

Can you see it?

It's so warm.

Does it feel good?

Kazuya...

My son's penis is hitting my uterus.

Right?

Soon there will be be six.

Right, Kazuya?

Sex is sacred.

But even if it's not,

if we can laugh together like this,

I wonder if there's any point to stop teaching it.
