Sayuki, the wife of a university professor, was still a college student when she got married. For several years, her sadistic husband trained her in SM every night... but the professor died suddenly of a cerebral infarction due to the intense sexual encounters, and Sayuki was tormented by a sense of loss. However, the beasts appeared, smelling the female's sexual scent wafting from under her mourning clothes... spanking, torture with extra-thick toys, intense slapping and rose whip, anal expansion and mating with a single whipping, and glycerin enemas. Sayuki became a lewd beast with a masochistic sexual desire and craved extreme training!
