In an extracurricular experience gone hilariously wrong, innocent Takashi Tono accidentally joins a club of young men who put the dick in valedictorian.

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?

Poor Takashi Tono, who joined his all-boys school's Photography Club unaware that the group's main extracurricular activity is offering its sexual services to the student body, also learns that his crush Yacchan isn't the angelic idol everyone thought! While still reeling from the revelation, Tono also has to reconcile with the fact that fellow first-year Yu Kashima doesn't just want to fake-date as a front to fool the sex-happy club-he wants to date for real!
