I remember many, many years back a tv program showed a clip from what I recall was an oriental Japanese fantasy film-the kind where I think they fly and swords and stuff-
But there was a scene where this man is trying to hit it on with a girl in a forest I think at night and he thinks he is about to have his way when from what I think she either cast a spell or started to play a flute or something, but the guy starts to moan and from under his robe his balls start to expand.
Its done in a cheap way, end up growning huge so its like two big balloons are being inflated but at last moment camera cuts to the woman again and you hear a bang and then you see that the man is holding himself-clearly that his balls have popped.

Anyone know of anything similar to this? I could be slightly off on some of the facts but many someone knows of something along these lines?
