Keiko, a true-born masochist, is kept and controlled by a middle-aged man, living as a livestock female college student in an animal shed. A training documentary has been released, recording her daily life from early summer 2010 to peak summer 2011. The footage includes whip stimulation, servitude performed in a straddle position, and continuous orgasms induced through orgasm control. Her emotional escalation and physical pleasure throughout the process are clearly evident. The video portrays her struggles to survive in the role of a servant, as well as joint training sessions with other female servants.
