Nasty Wife

Yoko Fukuyama is a horny wife who doesn't get enough sexual satisfaction from her husband, so one day she answers to an advertisement which promises hope for people who need more sexual gratification. Next thing we know, strange men come appearing at her home and putting Yoko in some intense SM bondage sex situations with whips and candle dripping. In the end, Yoko gradully drowns in a sea of pleasure, even in front of her husband while banged by the other men.
