The passionate, erotic days of these unassuming women.

This is the apartment 'Tokiwaso' where aspiring female erotic manga artists gather. However, the editor Wakamiya, troubled by their immature expressiveness, subjects a male editor to various sexual acts as an experiment to learn realistic sexual experiences. Using an editor with a large and exceptional physique, they take photos and make notes in various positions, and their passion to draw more skillful and realistic erotic manga doesn't end there. Each one studies the male editor under the guise of learning, sketching genitalia, the movement of breasts, the saliva of fellatio, the ejaculation of sperm, the dripping of semen after internal ejaculation, transparent oil massage, masturbation, lesbian sex, etc. And finally, a group orgy! Will successful erotic manga artists be born from Tokiwaso through this intense training?
