If you look hard enough you can find anything on WWW:

"One of history's most flamboyant human recipients of oral pleasure was the notorious Empress Wu Hu, who ruled China during the T'ang Dynasty. Wu Hu decreed that all visiting dignitaries pay homage to her Imperial Highness by performing cunnilingus upon her royal puss. Paintings depict Wu Hu holding her big ornate robes open, as a handsome nobleman kneels before her, lavishly applying his lips to the imperial pleasure palace between her thighs. "

A custom that I think should be re-instated immediately and not just for royalty
