Tsukasa, in her first year of marriage, was living a happy life that everyone envied. However, her husband, an elite stockbroker, embezzled slush funds from Sagawa, a powerful figure in the underworld, and disappeared. To settle the debt, Sagawa demands that Tsukasa satisfy his perverted fetish—he only gets aroused by women bound in ropes. To save her husband, Tsukasa accepts the bondage training... Lewd ropes dig into the hairless, secret flesh of the pure housewife. Trapped in a brutal snare, the beautiful wife falls into the shame of becoming a female slave.
