A seemingly happy married life. But Yumi's secret is one she can't tell her husband. She binds herself with a rope and posts it on a picture website. Yumi can no longer suppress her own lust, so she asks a bondage teacher she met on the site to meet with her and train her. Yumi is intoxicated by the pleasure of bondage and climaxes deeply and violently. Yumi is troubled by her immorality towards her husband, but she continues the dangerous encounters for the sake of the rope.
