Adult PC Game: Sokubaku Suru Ane by 13cm Archive

The story begins with the fact that the brother and sister are left alone after their father was forced to leave for business in another city.
The brother, who has long been in love with his sister, decided to masturbate, believing that no one would see him. Oh, how nice it is, he thought, wielding his right hand and inhaling the smell of his older sister's panties. Suddenly he realized that there was someone else in the room. It was his sister. The brother expected insults and shouts of "Pervert ...", but instead the sister gave him a gentle smile. However, her next words came as a complete surprise to him:
"Brother, from this day on, your member becomes mine, and I alone decide what to do with it."
