Wife: He can fuck you in the ass, but no kissing

So tonight my wife asks me "What would you do if a guy came onto you?"
I played dumb and said "I'm in a relationship"
She said she didn't think this would stop me, knowing what I'm like (horny)
Then she said "He can fuck you in the ass, but no kissing. Kissing is for me" Wow!
She know I like anal play and I guess she realises I'd like to know what it feels like to have a guy fuck me. I was still really surprised.

Is this a free hit?

fuck ya push it make it happen let her get fucked as u are

Then she said "He can fuck you in the ass, but no kissing. Kissing is for me"

This sounds like the start of something. Expand on it next time you’re talking about it.
Baby steps, unless she wants to take a giant leap.
