12 years ago, Kiki (pseudonym) was known as a submissive woman with strong masochistic tendencies, trained as a sex slave by a dominant man during her time as a university student. However, thinking about her future and family, she chose to suppress her submissive desires, parted ways with her dominant partner when she started working, and opted for a normal life—eventually marrying a few years ago and building what seemed like a happy household. But now, she unexpectedly reunites with her former master through a business client, meeting the man who once owned her after 12 years. In that instant, memories of her days as a sex slave come flooding back, making her peaceful everyday life feel dull and meaningless. The long-buried pleasure of female submission awakens once more within her. When her former master whispers her name into her ear, she trembles at the sound and pledges, "Please make me your slave again." This video documents the story of a married woman who voluntarily returns to her master and submits herself to rigorous slave training. The footage includes M-shaped bondage forced orgasms, toe-sucking service, pussy paddling, urine tongue-cleaning, anilingus, and cock worship. Kiki, who had been living a steady life as a professional office lady married to a plain, serious, and kind average man—having completely sealed away her SM past—now exposes herself once more as a sex slave. Her pitiful, degrading, and intensely masochistic emotions are vividly conveyed throughout this work. This production consists of a real amateur SM enthusiast's self-recorded submission video. There is no scripted acting, artificial production, or narrative elements—only raw, explicit, and authentic footage.
