It's good to trim it, but when people start shaving all that nice bush off that's when your nose get's itchy and without that bush you have to remove one of your hands from a nice place and lift your face to scratch you nose,,,, leave the bush let it out!
Some of us (not me) look back at this Vintage Porn Classic stuff with over-inflated reverence and nostalgia. But, many of the new short incest videos showing up these days in XHam demonstrate far better scene structure, camera work and pacing. They are simply hotter. Best to remember that those 70's films were groundbreaking incest role-play works that defied the censors. And from what I've been told, were actually shown in public movie houses. No way today, Jose.
