Porn Game: Do M Imouto no Roshutsu Yuugi -Dare ni mo Ienai Himitsu no Asobi- by Appetite

My sister "Miku" has a good personality, perfect beauty, and excellent grades.
She has no qualms to mention, she is exactly she is talented.

But one day I discover a ridiculous secret.
Miku posted a video posting site showing her masturbating in my room.
Why was Miku shooting masturbation?
Why is the shooting location my room?
Various thoughts fall into the snow and mess up my head.
I also thought about calling Miku and asking him directly.
But if she asks, "Did you masturbate in my room?", She would definitely feel awkward.

There is only one way to check the authenticity anymore.
Yes ... I just need to hold back the moment when Miku invades my room.
