For all the people that said no, because it smells like shit; you ever 69? One of the occupational hazards of a 69 is having a butthole drop right on your face, or at least be within sniff distance. Do you smell shit then? I hope not, but when you tongue the ass it's not like that inch closer all the sudden brings out the shit smell. If you smell or taste shit when your licking the asshole then you need a new woman because she is one dirty bitch.
I've licked my fair share of female ass and have never smelled/tasted shit. *knocks on wood
