Iiboshi Kumiko was diagnosed with cancer at a young age. Despite her declining physical strength, her urge for sex continues to grow day by day. Sometimes with fellow cancer patients, sometimes with passing men, and sometimes with female friends. Every day she goes crazy for sex, as if to burn out what little light she has left of life. "I'm not scared of dying at all. I don't have much time left anyway, so I'll do as many pleasurable things as I can before I die." This is the record of her sex and life.
