Kurîmu remon: tsubomi no katachi (2006)

Encouraged by friends, Ami, a 17 year-old-girl takes part in a star contest and captures the attention of Amamiya, the president of an idol management company. She lives with her brother, Hiroshi, a popular porn stills cameraman. His trick is that he sleeps with his subjects as he takes photos of them. When Amamiya fails to have his way with Ami, he decides to devise a scheme to get back at her. He knows that Hiroshi loves gambling and invites him to play. However, it's a trap; if Hiroshi loses it, he must take Ami's nude photos.
