【The Forehead】A story about a mischievous but pushy sister

[Oh, to thank you for comforting me, I’ll give you a kiss~?] …

My sister is a mischievous schoolgirl who is one year older than me.
As a student, I live with my sister in an apartment to save on rent.

As a younger brother, I can be the target of mischief without hesitation, but I secretly have feelings for my sister.

I’ve been enduring these pranks for a while now.

One day, when I was consoling my sister after she broke up with her boyfriend, I felt like my feelings were being trampled on.
I was at the end of my rope, so I called it “payback" and beat my sister…

Despite the awkwardness of our relationship, my feelings for my sister are strong, and she gradually becomes aware of them.

At that time, I bumped into my sister in the bathroom, and the sight of her without any clothes on made me feel inferior.

It makes my penis completely erect.

────[Are you going to get—[revenge]] again?

Not knowing whether you’re being invited or rejected, the [payback] begins again.
I have only endured mischief so far, but perhaps my sister — weak to push —?

After becoming a lover with my sister, I became more and more active in sex…
I’ve been invited to do naked apron, clothed blowjobs, even crab legs sex…

Finally, they started to want each other, and even had vaginal ejaculation sex to make a baby.

This is a CG collection of my own sister, who likes to be naughty but is not a pushover, and we get into a lovey-dovey relationship and have sex.

[kazuki
The younger brother, a student who is basically calm and enjoys playing with computers.

He is single-minded and has had a crush on his sister for over ten years.
He complains (in his mind) to his sister that she has no eye for men, and he is very jealous of her boyfriend.

He is a rational type, but he becomes very honest once he decides he doesn’t need to hide it. She is a pain in the ass.
He is very dirty and has more sexual knowledge than others. Too bad.

Satomi.
A big sister. She is a prankster and messes with Kazuki a lot. Her main prank is buying things for Kazuki.
When I was a kid, I used to kick Ikki in the face (less so as I grew up).

She has a good style and a good appearance, so she is popular there.

She was going out with her boyfriend, but broke up with him for some reason (the second time in a few months).

She is an expressive and active type. I’m not very good in the morning and I’m not in a good mood when I wake up. She likes Clover.

He’s a little more mature than I am, and I can rely on him mentally, but he’s just a family member and I don’t consider him to be the opposite sex.
I’m not a pushy person, and I’ve had boyfriends in the past who confessed their feelings for me and I just went along with them as if they were okay.

She is a little reluctant to do anything naughty, but once she gets lit up, she gets into it.

They have some pretty good sex in the book. She likes to do it backwards.
