Here is the translated description:
The Slave Club, a secret SM club, introduces the harsh and erotic training records of three genuine masochistic women who requested training. Led by trainer Ranki Kazami, this club is known for its cruel and intense punishments that can't be experienced in other SM clubs. This time, three women with different backgrounds came to request training. First, 'Yoko', a woman in her mid-30s with three children and a PTA member, arrived with a tense expression, claiming she was ordered by her husband to participate. However, her true self is a masochistic slave wife filled with lust, developed through perverted training. Next, 'Miwa', a naive masochist who just graduated from a prestigious private university, had no SM experience but strongly desired confinement training and voluntarily joined the club. On this day, she was taken to a member's villa and thoroughly trained until the next day. Lastly, 'Megumi' sent an email to volunteer for training, stating 'I'm a sexless masochistic housewife', and came to become a plaything for numerous men. With her ED husband's approval, she was trained to become a submissive, perverted woman who obeys every command. The video delivers a detailed portrayal of how each woman's different background and desires are transformed into masochistic pleasure through intense training.
