Mako Oda, a perverted big-breasted wife who secretly films herself having sex with others to please her husband.
I ended up staying with my brother and his wife for a while for a job interview. One day, her brother's wife, Mako, entrusted her with the key to his study, asking her to take a look at her brother's collection. On the computer in the study were hidden camera footage of Mako masturbating and having an affair. When she questioned Mako, she discovered that the camera had been set up by Mako herself.
