Sai Moon-Kin (Elvis Tsui Kam Kong) is a rich man who idolizes Lawrence Ng's character in the original Sex and Zen, and works hard to please as many women as he possibly can. When marrying off his retarded son, he finds his son's new wife (Shu Qi) pretty hot, so he takes her for his own, not knowing that she is the evil Mirage Woman, who knows "sucking" magic that's pretty nasty. Tsui's daughter (Loletta Lee), who dresses like a man and wears chastity belt for the main part of the film, and the righteous Iron Man (Ben Ng) try to stop Mirage Woman before it's too late, which means that she'll have free rein to "suck" anyone she wishes.

Sex and Zen II (玉蒲團二之玉女心經) is a 1996 Hong Kong film directed by Chin Man Kei. The film is a sequel to Sex and Zen (1991), and it was followed by Sex and Zen III (1998).
