I have a secret I can never tell my husband. It's about the time I became the sex slave of my husband's boss, Sagawa. Back then, I was obsessed with the thrill of that abnormal world, drowning in pleasure. But after meeting my husband, I cut ties with Sagawa and tried to return to an ordinary life. However, due to unavoidable circumstances, I'm once again tightly bound by hemp rope. Even as I try to resist, I'm overwhelmed by intense pleasures unlike anything my husband has ever given me, pulling me back into the world of bondage.
