"I'll deliver the masterpiece." This is the story of a secret about genitals that only I and my girlfriend know. I ran away from home and came to Tokyo. However, I soon found myself in financial difficulty, and the only job I could find was as a writer for a dubious adult magazine. A shrine maiden with a masterpiece who can get a man 100% erect just by praying. In a corner of the crowded city, I meet a beautiful girl. I accept the man's heartfelt wish to regain the happiness in his life that he had almost forgotten, and I get him erect and lead him to continuous ejaculations one after another!
