A wondrous prostitute plies her trade while living on a boat in Hong Kong. With a superhuman libido and three loving husbands, she doggedly devotes herself to her work. Using sex to satirize the era, this film brims with intense desire.
There's a better copy at the torrent sites.
47:33 Husband (or the youngest of the three husbands) finds his wife getting fucked by a neighbor in one of the apartments in their building. A lot of things are happening in the movie aside from that, of course, including the husbands pimping the wife and letting men fuck her at the latter half of the film, mainly because she's really horny like it's a medical condition.
