You have finally achieved your dream of becoming a manga artist's assistant. However, what makes this job a little different from the norm is that your employer is a female author and adult manga artist, and to save money, the contract requires four of them to share you. Although they usually have endless erotic fantasies at work, they have little real-life experience, so they use your body as they please, using the excuse that it is for the sake of their work. With teachers who each have their own sexual fetishes, your work as an assistant with no labor standards begins.
