You play as a college student named Hiroyuki, and the story centers around an internet site called "P.S.". The site consists of five different women who live dual lives, as they each have a darker side to them that reveals their true sexual identities. There is Akane, an elevator girl who is into exhibitionism; there is Aoi, a secretary who likes to be raped; there is Haruka, a sports instructor and Kaoru, a flight attendant, who are both into heavy and public masturbation; and finally there is Sakura, a TV newscaster, who is into something called "scat"(you may find that very disturbing and offensive). There is also Jun, who is Hiroyuki's tomboyish girlfriend. Hiroyuki plays as "master" of the P.S. site and to the five women.
