Popular erotic novelist Maesaka fell into a severe slump and spent days unable to write a single line. The frantic editor-in-chief of the magazine sent Shiori, an amateur newcomer, to collect manuscripts, but the naive, busty, ruined daughter instantly captivated Maesaka's libido with her innocence and shyness, and gave wings to his perverted delusions, sending them into his brain. The perverted image that swells in the middle of the day will produce the best masterpiece of the generation, but eventually the delusion will treat the real Shiori as a sadistic sex slave, and the intense excitement will dissolve the boundary between the two.
