Kaori, a married woman burdened by her father's factory debt, marries Genzo, a university professor twenty years her senior, under the condition that he clears her family's financial obligations. Bound by guilt, she is forced to submit to Genzo's insatiable and abnormal sexual desires. Genzo, who has stolen research papers from his graduate students Odagiri and Sanada to claim as his own, is despised by them. Now, they will take their revenge by stealing away the one thing most precious to him—his wife Kaori—through the most humiliating means possible: tight bondage and perverse sexual training. The story unfolds as Kaori's body and mind are torn apart, while Genzo's lust and guilt collide in a twisted game of betrayal and domination.
