姉, ちゃんとしようよっ！ 第1話 

My name is Hiiragi Kuya. Actually, I have 6 elder sisters. The eldest sister is Hinano Ne-san although she looks quite young. She is worrying about that, so if she is treated like a child, she gets angry.   

The second sister is Kaname Onee-sama. She is a popular lawyer and known as “Icy Lawer”. In fact, she is my first love.

The third is Serori Ne-Ne. She is a half Japanese and half North European. She has most voluptuous body in the sisters, but her act is very childish.

姉, ちゃんとしようよっ！ 第5話 

When I was a child, I was adopted by Hiiragi family. But because the father was afraid that the sisters would spoil me, I was sent to a relative to train myself. It is the first time to go home since then.

I was very exciting to see them again, especially Kaname, my first love. They welcomed home, but late at night, Kaname Onee-sama raped me, and treated me like a toy. I felt very ashamed and I made up my mind to train my sex technique to put her to shame...with help of other sisters.
