Sayuki, the wife of a university professor, was still a college student when she got married. For several years, she was subjected to SM training by her husband, who had a strong sadistic streak, every night. However, the professor died suddenly from a stroke due to his overly intense nocturnal activities, leaving Sayuki in a state of loss. But the beasts appeared, drawn by the scent of her feminine arousal beneath her mourning clothes: spanking, extreme toy torture, fierce slapping and rose whips, anal expansion intercourse, single whip lashing, glycerin enema. Sayuki transformed into a beast of M-sexual desire, craving extreme training!
