KA-1150 - The Holy Scripture of Lust: End-of-the-World Ecstasy

For a film from this era, the mosaic work is groundbreaking. In the opening fellatio scene, the male genitalia are whited out just like in modern digital mosaics, so you can clearly see the tongue technique. In the sex scenes, they use a white-out effect similar to the Flashback series, but you can still see the pubic hair. They also use a split-screen technique showing close-ups of the face and lower body simultaneously, which was quite experimental for the time.
