Celebrating Million Girls' 2010 first collaboration! A youthful club activity story about sex-loving members who are beginners at instruments, set in a girls' school's light music club! The light music club is on the verge of being disbanded, so Shirley and Wang as lesbians to join! At the training camp, the instructor's finger technique makes the three girls cum over and over again, making them completely crazy! Plus, at the school festival, they hold a massive orgy party with the boys from the school! The youthful school sex of the schoolgirls played by Milliga is about to begin!
