体育倉庫～少女達の散華～

Once upon a time, Ryouta Nagase was a very successful salesman, mostly because he routinely supplemented/enhanced his commercial skills by seducing and bedding the female customers, but tragically his past life is now only a painful memory since that fateful day when he lost his job and perhaps even his drive to live after becoming impotent...

Drifting aimlessly from place to place, almost destitute, Ryouta is forced to seek refuge for the night in the gymnastics warehouse ("taiiku souko" in Japanese) of an abandoned school somewhere in the countryside.

Unfortunately, the following morning he's discovered by Rikka and Miko, two little (but 18 years old of course, heh... ) girls who are using that same warehouse as a sort of secret room for their summer homework and other childi... , err "girly" activities.
