Eating Butt...

Last night I jokingly told my husband that I was going to eat his ass (I, in no way shape or form have ever wanted to do that. I was in the moment joking around with him.) But he said okay to it. I was surprised how willingly he sounded.

So my question is to anyone who has eaten their husband's/SO butt, how was it? Does it taste nasty? How is that even supposed to happen? Am I supposed to play with his asshole with my tongue? I personally do not like the feeling of him eating my ass.... So I don't know what to do at all..

I don't think I'll ever go through with it.. but who knows? advise & experiences will be much appreciated.
