Sex is punishment? That almost fits what appears to be a Japanese philosophy as evidenced in their tradition videos where the girls, with a painful expression, usually close their eyes or look away when getting laid. However, this tape features women as the aggressors. That happens in reverse here.
They say that post war (WWII) socks and women are what became stronger in Japan. They really do say it - on screen. English subtitles reveal all in this very different Japanese story about a trio of lovely girls who are fed up with their Japanese men acting wimpy about sex. They turn the tables, and all three jump one of these Mamas boys. The poor schmuck doesn't know what to say or how to act; this is obviously something he isn't used to and apparently feels he can't handle. And (gasp!) he is forced to eat pussy while blindfolded by panties and even gets fingers up his ass. Total humiliation.
