This special production compiles footage collected over one year by an SM magazine editorial team. The subject undergoing training is Keiko, a human livestock who has vowed to live solely as a sex slave. Though her slender, delicate body still retains a youthful fragility, she has remained devoted to Mr. Tsukushi for over a decade since her days as a female college student, living a life of daily masochism. Currently working full-time as a care welfare worker, she spends all her remaining time in the livestock shed, undergoing constant training to become a true 24/7 sex-dedicated masochistic animal. Witness the raw, unfiltered record of a genuine female masochist's life over the course of a year. [Before Purchase] This work consists of real-life SM play footage shot by amateur practitioners.
