Some people just dont understand the significance of licking ass. Especially when she has a gigantic ass with a pretty tight little hole. BBW/SSBBWs deserves to have their ass spread and licked until she has enough.
Yes, White American culture, strongly influenced by Puritanism, is aghast at even the mere concept of ASS, whereas Brazilian culture---a melange of Catholic, African, and Amerindian contributions---celebrates ASS in so many wonderful ways.
My first wife was Brazilian and she was always wanting me to eat her asshole. To this day, I am truly amazed at how normal analingus is in Brazilian culture, how commonplace. For an American like me, it was quite the awakening.
