Onii-chan Oshiete -Gimai to Himitsu no Hoken Jisshuu | お兄ちゃん、教えて…… ～義妹とヒミツの保健実習～

It is yesterday that i remembered.

[With a body of Onii-chan as the teaching materials, tell me the health and physical education!]

Yuri of younger sister who goes to nursing school. It was thought that it walked well on the road to the nurse, apparently "If it does physical thing to man's body, the head becomes pure white".

However, making my body a teaching material... How what? May i do such thing by brother and sister? How many even if it doesn't connect blood...

The younger sister had come back before settling the idea. The younger sister seems to have forgotten last night's promise. Though i felt relieved secretly...

[Onii-chan. Tonight... Class of health education and physical education, it does...]

I have nodded so that it is thrown into the word. Tonight, how do it become? When thinking about it, the pulse of the chest became it quickly...
