Two years after Kaori's systems-engineer husband started his own business, the once-promising company has fallen on hard times. As the bad news piles up, he drinks more and stops having sex with her. Desperate to save the company from bankruptcy, Kaori agrees to offer her body to investor Asami. After she steels herself for what is coming, Asami binds her tightly with hemp rope. Kaori desperately resists his perverse demands, yet her long-neglected body gradually begins to throb with desire.
