The ultimate fantasy of a married woman with a hidden masochistic nature comes true here. Rieko (pseudonym) has long dreamed of being tied up and tormented, craving the blend of pleasure and pain since childhood. Having had no real sexual experiences, she spent her days immersed in self-degrading fantasies. Her first partner was a man with normal desires, and drawn by his sincerity and kindness, she married him. She suppressed her masochistic urges to live as an ordinary wife. However, in her eighth year of marriage, longing for children yet unable to let go of her fantasies, she responded to an ad in an SM magazine, beginning her journey to fulfill her deepest desires. Tight bondage, pleasurable torment, anal play, punishment with Buddhist altar candles, spanking—this carefully filmed record of her first-ever BDSM training session offers an intense, immersive experience into the profound ecstasy of a true female masochist.
