One day, the sister who has been rubbing her brother the wrong way gets revenge by tentacles!


I want to make my sister, who always bullies me, cum with my tentacles!

I want to make my sister who is always bullying me cum with my tentacles!
The sister who uses her brother as a pawn.
The sister who looks down on me like I’m trash.
But my sister is no match for me in sports, studies, or by force.

Here is a CG collection that will fulfill your desire to make such a sister [understand with tentacles].
[My anger has reached its peak and I’m going to take revenge on my sister with my tentacles].
Here is a CG collection that fulfills my desire to make my sister understand.

In this CG collection, the sassy sister heroine takes revenge on her brother who has acquired the power to control tentacles.
This is a CG collection of a story where the positions are finally reversed.

This is a story of an older sister who is strong with her younger brother at first and never expects him to come back at her.
This is the story of a young woman who is forcibly trained by tentacles, and is forced into a body that cannot live without her brother’s cock.
I’m sure you’ll enjoy this one as much as I do.

~I’m sure you’ll like it.

-Tentacles restrain my sister, lift her skirt, let the tentacles invade her pants and make her cum with her clit!
-Take off her bra, expose her tits, and suck on them with tentacles!
She has a tentacle in her mouth that emits an aphrodisiac liquid, and she shifts her pants to insert it! Take away her virginity!

-She calls her sister who is doing club activities on the roof of the school, and makes her give a tentacle blowjob to her sister in tennis wear!
She makes me lift up my skirt and shove my tentacles inside my pants to stir them up!

After taking off all her clothes, she pushed her sister from below until it was time to leave school.

-Discipline your sister without a break after you get home! She masturbates and pees and records it!
She has a boyfriend, but her sister’s pussy is thoroughly developed with tentacles so that she can come right away with her boyfriend for the first time!

-It’s a great way to get the most out of your sex life.

The mainstream of this work is to make the sassy sister understand.
This is the first time I’ve used a tentacle in a CG.
If you are an expert in tentacles, this may not be enough for you.

But on the other hand, if you’re a tentacle novice who likes sister and brother stories and things that make you understand, but you’ve never seen tentacles before, you can still enjoy them.
I’m sure you’ll find it easy to get into, so I recommend it as a good introduction to tentacles!

The heroine has a boyfriend in the story, so there are some NTR elements in the story.

There are no tentacle spawns, nurseries, bellybuttons, lyona, scatology, or gore in this story.
If you don’t want something too hard, don’t worry, you can still enjoy it.

We also have a free trial version of the game for you to try before you buy.

My name is Shoji.
I have a sister who is far away from me in age. Her name is Akane.
I’m the younger brother, and I have to say that my sister is quite beautiful and cute.

That’s not all. My sister is also a good athlete, winning the tennis tournament. Her grades are also very good.

She gets almost perfect scores on every test. She also seems to have recently found a boyfriend.

You can say that he is a perfect superhuman.

Is that too much praise? You can’t help it, it’s a fact.

But… you might envy me if you hear all this, but it’s not like that at all.

Because my sister is the worst, meanest, scariest, most savage person I’ve ever met.

I’ve never disobeyed my sister in the past. No, I have, but every time I have, she has thrown me with her signature Ippon-bakari.

I’m sorry, but I’m no match for my sister in fighting, studying, sports, or even games. There’s nothing I can do to beat her.

That’s why I don’t disobey her anymore. My sister takes advantage of this to tease me day in and day out, and she’s happy.

I’ve been thinking about getting back at my sister for some time, but there’s no way I can do that.

Yes, until that day came…

One day, when I was cleaning the house at the behest of my sister, I found an old bill in the back of the closet.
I remember my dad, who was a bone fide, buying one of these as a souvenir of a trip or something.

I’m sure you’ll be happy to know that I’m not the only one who’s had a bad experience.
I somehow picked up the bill.

I’m sure you’ll agree with me.
[Do you want revenge on your sister?]
What the hell was that? I wondered for a moment, but then I unconsciously nodded.

I’m sure you’ve heard of it.
I’ll give you my power, then.
The next thing I knew, a mist-like substance erupted from the bill I was clutching.
I’m sure you’ll agree that it’s a great idea to have a little bit of fun.
I was so startled that I tried to let go of the bill, but for some reason I wasn’t afraid anymore.
In fact, I was strangely excited. It was as if I had new powers.
I’m sure you’ll be able to understand why.
This bill gave me the power to avenge my sister.

I naturally thought so.

It didn’t matter to me what this bill was.

I’m going to use this power to get revenge on my sister!
I ran out to my sister’s room, clutching the bill in my hand.
