Odd semi-pornographic prisoner of war film


Hello folks,

I've been given the task of trying to find out the name of a film, but I only have certain bits of information.

From what I've been told, two soldiers (of undisclosed nationality) are captured by korean/japanese/vietnamese soldiers, put in a hut and tortured. As they try to escape, one of them is shot in the back and the other makes it his mission to find his shot comrades wife and tell her the news. He does this on demob and finds the woman in question and moves in with her. She apparently has a sideline in what sounds like prostitution ("givin 'em blowjobs and jerking 'em off" is what i was told). Eventually, towards the end of the film, she decides that it's time to have some horizontal fun with this soldier, who gets the shock of his life when he removes her underwear and find a well endowed member.

I know nothing else other than its a one word film title. No idea of actors, country of production etc, only that it was "from the 60's 70's or 80's".

Any ideas folks?
