the wizard packing a girl's booty full of rice so he could make a rice ball out of it for a love spell (the object of the spell had to eat the booty-flavored rice ball).
You always find good stuff like this! All I get is movies with women dressed in potato sacks.
To completely flesh out the description, I should also let you know that blood and hair from the man (that the girl wanted to fall in love with her) was added to the rice ball sauce. So it was a booty-flavored hairy rice ball tartar.
I saw this one years ago on a crappy cropped VHS tape but I think that it was cut and not the complete film.
The previous VHS tape that I had encountered was cut. It's possible the source was a tv broadcast, been too long to remember much else. The film definitely caught me by surprise a few times. "Whoa! Didn't remember that!"
