Does your wife enjoy the back door?

Do any of the hot wives enjoy getting it through the back door? If so can you share any pic or vids. Mine only occasionally lets me but rare.
 
In my younger years I tried to butt fuck every girl I was with, some said no way, some reluctantly said ok but clearly didn't enjoy, some said ok and did enjoy, some said they had never done it but obviously had.
Wife and I tried 3 times in 20+ yrs married, never went well.
About 4 years ago we got into mfm with a guy we know, he did her butt one night and she was good with it. Since then he's done anal with her many times as have I. She has to be really turned on for anal, when he's with us she gets really turned on so anal does happen.
She grunts a lot when she's taking it in her ass, it's hard to tell if she's into it or not. One night he was in her butt for quite a while giving her really slow, full length pumps. When he was finished she looked at me and said WOW.
