I let friend to taste my wife's pussy, but?

I let my trusty friend to taste my wife's pussy, but he fucked her too.
I am married to a woman i love and a woman i absolutely believe in. I am very proud of my wife, she is beautiful and very sexually challenged, but still an innocent woman.
I often spoke proudly with my friend about my wife, and he about his wife. He even showed me movies from the sex scene with his wife. I didn't do this with my wife, because of without my wife's consent, i don't want anything to reveal behind her back. During the foreplay, before sexual act, i often point out to my wife that she has so beautifully shaped little pussy, and also delicious with very tasty juices from her nicely rounded, tight tiny pussy, which nobody knows about. I would be proud to discover this such a wonderful secret.
I knew that my friend liked my wife, and she knew it from me also, so she often dressed irresistibly provocatively, because every woman likes to be desired by a man.
So one day my wife wanted to fulfill my wish and somehow she agreed, to massage her together and after that he could discover the secrets of curves from her beautiful pussy, and tasty juices from her pussy.
The beginning of the massage was careful and very classic, however it all turned into an erotic massage of an innocent woman by two men, her trusted husband and his friend.
eventually i let him massage all the parts around her pussy, and her entire pussy too, while i massaged her boobs with huge swollen nipples.
My wife was no longer able to resist the pleasures of such a beautiful enjoyment. My friend used this advantageous situation skillfully, and pushed his head between her widely separated legs, and began to lick her pussy by drowning in her wet pussy full of delicious juices.
He stripped off his pants and underwear, his dick was hard and bigger than he looked in the movies, he plunged it into her pussy, with penetrating her mercilessly to the end, and so hard, she moaned loudly with all pleasure, rotating her hips, so that her pussy was so wonderful dancing, with his wet soaked dick into her honey juices. I was so horny still massaging her tits, watching her beautifully playful body. Something unexpected happened, my trusted friend, and my so innocent wife, enjoying the best sex ever with each other. Of course, after such a massage, and in such sex she caused several strong orgasms, after which her collapsed body sank into the deep sleep of the seventh heaven.
my wish was just to show him the nice curves of her pussy, and to let him try nice taste from juices of her pussy. But it all turned into very hard sex for both of us, with my wife and all that night. After all this unexpected experience i ask myself? why did I need all that crap? Did i do something wrong, or not? what should i do in our marriage, with my so hot innocent wife?.
