The protagonist of the story, high school student Igawa was forced to stop by his classmate Yana on his way home, who has been missing classes for a long time due to illness. He was surprised to find out that the reason for missing classes was not a cold, but the girl's insatiable desire to draw yaoi manga all the time. After looking at her work, he pointed out some inconsistencies between her artwork and reality. Igawa jokingly offers to correct the mistakes in the girl's drawing from her own nature. Jano did not appreciate the joke, and in all seriousness offered the young man to show her in detail all the details of the male anatomy. She even took the first step, boldly exposing her lush breasts to Igawa. There was no room for retreat... But, the girl did not take a pencil in order to capture the nature on paper, she rushed to study the "object" of her interest in the best possible way. Hands, lips, pussy, etc.
