【S girlfriend / Asuka Maki】The second of the two younger sisters.

The fifteenth installment of the Instant Nuking Slut series is about a younger sister (the second one) who does naughty things to her sleeping brother (you).
This is the sixth installment of the [Sleep Adultery] incest story for you to listen to while you sleep.

Your cute little sister is cool, but delirious for you.
This is the sixth installment of the [sleep rape] incest story for your listening pleasure.

You are sleeping soundly and will not wake up no matter what your sister does to you.
It’s a great way to get to know the people in your life.

You really can’t wake up no matter what they do to you.
I don’t wake up when I ejaculate, so my sister can do whatever she wants.

Please note that there are no reversals or situations where you (the brother) attack your sister in this movie.

01
I licked my brother’s penis after he fell asleep while masturbating, and he ejaculated easily.

02
Now that I’m used to blow jobs, I’ll try to taste the ejaculated semen with a hand job as well.

03
I masturbate and suck his cock in a six-nine position, and climax at the same time.

04
I insert myself into my sleeping brother in cowgirl position, but stop immediately when it hurts too much.

And I’ll make him ejaculate with a blowjob.

05
After all the preparations are made, I start over for the first time.
This time I was able to do it better, and my brother had to ejaculate into my vagina twice.

It takes about 53 minutes for my sister to get messed around with.
You will be allowed to ejaculate on all tracks 01-05.
You can choose to listen to it with (A) or without (B) the naughty sound effects. Please listen to the one you prefer. However, some tracks may not include the SE.
BGM is not included in this work.
Please check the demo version (about 7 minutes) for an image of the content.
