I became a housemaid for Mr. Kudo, my husband's boss, and accidentally witnessed his wife Akane tied up in tight bondage. In that instant, his secret was revealed, and my body was completely bound by hemp rope, overwhelmed by intense pain mixed with pleasure. Unable to endure the sensation, I quietly entered into a contract as a sex slave, something I could never tell my husband. The stimulation of the hemp rope gradually took control of my mind, and now my obsession with bondage grows deeper each day.
