My Wife Wants An Ass Licking

For most of our 30 plus years a marriage my wife didn’t want me to play with her ass in any way. She believed there was something wrong about it but she could never quite explain her feelings.
This all changed a few years back. We were out at a bar and came home feeling no pain. When we got into bed she grabbed her wand, rolled on her side with her butt facing me and went to work on herself. At this point I started rubbing my dick between her ass cheeks. After a minute or two she says very clearly fuck my ass. Now as much as I wanted to do just that, I thought it would be better to finger her ass sense she wasn’t use to ass play.
This was the start of the best sex of our lives. She now asks me to to finger her butt on a regular bases as she uses her wand on her clit. I love to feel her anal contractions as she cums.
Usually I am the one who suggests something new . Lately though she has indicated she wants me to lick her ass. Now I am more than happy to go there , but I am uneasy about doing it after I have been fingering her ass . Maybe I should just go for it but one way or another her beautiful butt is going to get an ass licking sooner then later.
