A few of my g/f's enjoyed it a lot. I would usually eat her ass while fingering her. She like that alot. Sometimes in a 69 with her I would also do that.
Man, you better wash your mouth out with some peroxide pretty quick after doing that (and certainly make sure you don't do any inadvertent "swallowing"....yechhhh!!! :throwup . E. Coli or Cryptosporidium are not pleasant experiences and both can be fatal so my advice is....:nono:
I absolutely love eating a woman's ass while going down on her. I've never had it done to me before out of shyness, but I think I'd really like to try it.
