The best thing about these old classic movies is the natural beauty of all the women. No fake tits, asses, lips, skanky tattoos, piercings. The way women are supposed to look. Women today ruin themselves with all of those things and think it's attractive, it's tragic.
I agree with Emissary that the natural looking women in classic movies are good. Porn movies like this are a fascinating in that the people making the movie seemed to take the story and acting as seriously as the sex. Probably shot to run on the screen in some seedy theater. Once home video came around porn watchers just fast forwarded from sex scene to sex scene.
