Ryuuki Kirishima is a boy who lives with his older sister, Reiko, after the tragic death of their parents in a car accident. One summer day, Ryuuki and his friends gather to watch adult videos for fun.

As he watches, Ryuuki feels a strong attraction to Kiriru, and to his surprise, she appears before him in person.
