At an all-boys' boarding school deep in the mountains, hapless transfer student Takashi Tono joins the Photography Club, only to learn too late that the club's main extracurricular activity is offering its sexual services to the student body! Now that Takashi's surrounded by bedroom aces, can this virgin survive a day, much less the whole school year, as part of the school's most lascivious club?

In a bid to stave off the sex quota required of the promiscuous Photography Club members, first-year Takashi Tono has protected his virginity by fake-dating fellow club member Yu Kashima. But while Kashima's affections are real, Tono still has a crush on his sweet-and-sour classmate Yacchan--and so does club upperclassman Tamura! When confessions spill out, hearts will break! But could something even more scandalous be afoot when club president Akemi reveals a long-held secret?
