Keiko, a genuine masochist girl, lives at the lowest level as a submissive sexual servant to her middle-aged male owner. Identified as a livestock female college student, she is confined to an animal shed where she undergoes daily management and joint training sessions with other female servants. This documentary-style footage, recorded from early summer 2010 to midsummer 2011, includes extreme scenes such as self-bondage, rope torment, anal sex, and lowest-tier female dog mating. The video captures how Keiko's innocent masochistic nature transforms under her owner's complete domination.
