I suspect that many of the shaved pussies we see here are shaved because the women are photographic models , and can't show any pubic hair in glamour pics, so are shaved so they can be as risque as possible without showing anything.
I used to think that shaved pussy from the 1950's was a rarity. I'm now having other thoughts! Absolutely delicious!! Being a sucker for (and of) puffy nipples, the angel at 53:15 has to be my fav!
