00[Big sister, I became a succubus for my little brother](6:33)

You come home, you have dinner with your sister.
I’m sure you’ve heard of it.

[Actually, I met [the devil] on my way home from school the other day.
[Actually, I met [the devil] on my way home from school the other day, and he said he could give me [the power to charm others].
He said that if I wanted to, I could control the minds of people I like and people I don’t like, just like I wanted to.
But in order to get that power, I had to make a [contract] with the devil.
That means I will become a demon too.
I’m sure you’ve heard of it, but I’ve never heard of it.
Succubus is a demon that controls sex.

I’m sure you’ve heard of it, but you’re not the only one.
I was going to be a succubus…] [

01[Gently sucking on a morning erect cock](16:00)

When I wake up in the morning, I feel something strange in my lower body.
When I turned the covers over, I found my sister smiling in ecstasy with my brother’s cock in her mouth…?

I’m sure you’ll find a lot of young girls at your school or cram school, right?
It’s not healthy to wear skirts that are too short, I think.
I’m sure you’ll be happy to hear that.
It’s not healthy to wear short skirts.
Mmm…chuuh. Chuuuuh. Hmm.

Phew, hmm.
So, hey.
Oh, no. Mmmmmm…

Thus, in the morning, your sister will give you a blowjob.
You need to make sure you squeeze out enough semen for the day.
I’m sure you’ll be able to find something that works for you.] [

02[Reward for my little brother who is studying hard♪ Ear licking and masturbation support](21:34)

You were studying in your room.
Suddenly your sister walks into your room and asks if you masturbated.
When I replied that I didn’t, my sister whispered to me that she would help me…?

[Hmm. I’ll lick your ears as well.
Hum…ch…er…er…ch…ch…ch…ch.

Mmm…reero reero…mmm…chu. Hmm…loo…chu…hmm.

Mmm… does that make you feel a little naughty?

I’m sure you’ll be happy to hear that.
I’m sure you’ve got a good erection.
I got a boner enough to masturbate, but just a little bit more…] [

[wraps it gently in his hand
Up and down, shimmy, shimmy.
Shiko, shiko.
Yes, yes, very good. You’re very good.
Keep going.
Shiko, shiko. Mmm-hmm, yeah, yeah.
Embarrassed?
お姉ちゃんに見られながらオナニーするの、Embarrassed?
This is the most sloppy, defenseless and shameful time for boys…]

03[Jealous sister punishes me with aphrodisiac saliva](17:18)

You’ve come home from a side trip with your classmate Akari.
When you get home, your sister is very angry.

[Your sister will rehabilitate you.

What, a kiss? I’m sure you’ll be able to understand why.
Mmm…chu…hmm…squirt.

It’s a kiss.
Puh-lease.
This kiss is called a charm kiss, and it’s a special kiss that only succubus can use.

It can make the person you kiss fall in love with you. Phew.
Mmm…rello…sizzle…

Hum…chu-chu-chu. Hmm…chu-chu-chu.

To make Shaw a great boy.
You have to get rid of any woman who gets in your way. I’m sure you’ll like it.]

[My cock is jiggling around in my boobs.
It’s a good idea to keep your saliva in your mouth and let it drip down into your cleavage.
Hmmm…

This will make it slippery.
And since it’s succubus saliva, it can make your cock feel better…]

04[Thick sex with succubus sister](15:20)

You are in your sister’s room, studying with her.
As a reward for answering all the questions correctly, you get a rich kiss from your sister.
You’re in your sister’s bed and you’re having sex with her.

[Hey? You haven’t masturbated yet today, have you?
I’m sure you’ll be happy to hear that.

Let’s go cunt with your sister…] [

[mmmm, mmmm, mmmm!
I can’t believe it.

I like it, I like it, I like it, I like it, I like it, I like it, I like it.
I love you, Shaw…]

[haha, haha
I’ll give you a big hug, sis.
I’m going to make sure that every last drop goes into your cunt.

I’ll suck you down to the root.
I’ll ejaculate in that state…] [
