All About The Butt

So my slim young wife grew up in the suburbs in a not rich but very well off family. She went to a private school but lived at home. Her experience with boys was limited to some kissing and titty feeling at parties and some make out sessions in parked cars. When we met she was working a nice entry level job in a major corporation. I was doing some training at her company and we interacted a little at the coffee bar and after my work there was completed I was going to be traveling for a couple of months but I gave her my mobile number and she gave me hers.
We texted some and by the time I was returning to the area it had turned to sexting.
I took her to dinner at a very good steakhouse and began seeing her a couple of times a month, then more like once a week and eventually more than that.
She had come to my place because she was still living at home with her folks at the time.
We had the kinds of sex you have when you first meet and then you're all over each other.
We were married quietly after about six months and have been really happy together for a decade now.
The reason for this confession is my wife has become and oral and anal fanatic.
She still likes ordinary sex and even once in awhile missionary style, though we both prefer doggy where I can get really deeper penetration and give her a good pounding. My dick is pretty decent, a little longer than average at about 8 inches hard and is pretty thick too. She doesn't always cum by fucking but she's very sensual and I can make her cum easily by hands or by eating her sweet pussy. She has even squirted a few times, which was a surprise to us both.
Anyway, back to her love for anal.
We started with me fingering her ass and then using very small plugs and small dildos and vibes.
Now she can take a fat toy and a good four fingers up her ass. I expect soon I'll be fisting her butt and she always plays with her pussy while she's getting anal and cums very hard and strong.
The confession is we have fantasized about her getting a good assfucking and my own fantasy is I'd like to have her securely bound to the bed at a cheap motel and have 3 or 4 very hung Black men give her that assfucking of her life.
Don't know if will ever happen expessially with the new covid variations and we're staying pretty isolated from strangers but maybe one day...
