健全なアイドル活動には性処理が不可欠ですっ！

Our protagonist was feeling poor after spending all his money to support the extremely popular idol group "Freya." So he applies for a part-time job at Freya's management agency "Love On." He manages to get an interview, where he is asked cryptic questions about whether or not he has ever had sex, how often he masturbates, etc. He somehow passes the interview and gets the job. His assignment is to be the "sex manager" for the five members of Freya and their extremely strong libidos...! Even though he is a virgin himself...! (Source: Yanmaga, translated)
