Houkago wa Betsu no Kao

A collection of four short stories featuring sexual experiences of school girls:

1. 「通学電車」

2. 「先輩・・・・・・」

3. 「進路指導」

4. 「非行少女」

A distinguishing feature of the work is the presence of narrator girl who also appears in the stories. But overall it's a very specialized content.
