JUQ-404: wife does nude modeling for a photographer, cheating with her boss, Sayuri Hayama

Sayuri Hayama is married for a year when she tells her husband she wants to try nude photography. He complains to his boss, Mr. Oshima, who arranges a photographer anyway; that night, Oshima visits and pushes the idea, and Sayuri agrees to do the shoot to appease him. She ends up naked in front of the camera, and later with Oshima.
