"Etcetera" describes quite well the content of this game, which is the third volume in the Gokko series. While the two previous games were dedicated to certain themes or scenarios (doctor and school girls, respectively), the third one is a collection of multi-thematic stories of a sexual nature. The protagonist is a young Japanese male (default name Shouhei), and his first objective is to seduce his boss's sexy sister. In following chapters, the hero encounters other women (sports car driver, journalist, etc.), each encounter ending the way one would expect from a bishoujo game.
