One girl giving two guys a blowjob at the same time? A foursome with the guys facing each other? Those were totally invented by Brazzers, a product of modern super-offensive pornography, right?

Bzzzt, wrong. It's the product of artsy Enlightenment and Victorian artists, who sit around thinking of sex when they're supposed to be illustrating books. Like these ones: sure, they're supposed to make an illustrated alphabet for adults, but let's go really adult, some Russian artist from the early 20th century decided. Don't get too excited about it being a product of our century - sexy letters go back hundreds of years and cover much of the world. Well, not China or Japan I suppose: artists trying to make erotic alphabets of the complex eastern symbolic languages went insane from the undertaking.

Via.
