Rei is a career woman who is enthusiastic about her work. It's been two years since I got married, and every day I'm not satisfied with my sexual life with my husband who is a year away. One day, I see a sex video on the net. Rei who is interested arrives at "bondage relaxation" while surfing the net. When I try to experience it, I feel unusually excited by the oppressive feeling of being restrained and the feeling of a rope grabbing the clitoris.
