not jav, but the japanese mainline film and 1985 international hit "tampopo" by juzo itami contains a memorable and marvelous egg sex scene.
back in the late 80s, i knew a couple of girls who wanted to re-create the repast from "babette's feast". knowing that they couldn't make a peanut butter and jelly sandwich and trying to keep things simple, i said "why don't we just do the egg scene from 'tampopo'?". jesus. some chicks have no sense of humor. they didn't even invite me to the dinner.
