Sister, let's do it properly! / Nee, Chanto Shiyou yo!

The main character of the hentai, Kuya Hiiragi, is the youngest son in the Hiiragi family. He lives in the same house with his six sisters. The eldest is named Hinano - she is short and looks much younger than her sisters, and many mistake her for a little girl, but this fact greatly irritates her. The second eldest is Kaname - she is a successful lawyer, known among her colleagues as "Ice Lawyer", by the way, she is the first love of our hero. The third sister, Serori, is half-Japanese with the most capricious character, but at the same time her body stands out among all the sisters. The fourth little sister, Tomoe - looks serious and even causes fear, but inside is a shy, cute little angel. The fifth, Takane - is generally a "lady", there is no other way to describe her character. And the youngest little one, Umi - adores the main hero and doesn't leave him alone for a moment.
