A rumor spreads about a rising beautiful erotic manga artist seeking assistants, and with full enthusiasm, several applicants end up getting hired by chance. However, her "enthusiasm" is actually directed toward sex. The actual job duties involve serving as live models for drawing male figures in her manga. Surprisingly, the other female assistants are also stunningly attractive, boasting soft, meltingly large breasts. They engage in erotic experiences such as breast fondling and blowjobs. But as they get caught up in daily sex, their physical stamina gradually wears down, raising doubts about whether she can truly continue creating manga while immersed in constant sexual activity.
