Mibojin Hentai Jigoku (1991)

A married couple enjoy engaging in S&M sexual behavior, and the wife, Yuri, asserts, "The ultimate SM play is death." After her husband dies, supposedly accidentally, Yuri is left alone, grieving and self-destructive. Her mental state deteriorates as she watches and masturbates joylessly to the home-made SM videos she made with her husband.
