Naked Wives

Earlier this summer we went on a camping trip with a couple we have known for a while. We were at a public lake, but it was a fairly secluded couple of campsites we took up. As the other husband and I watched my wife, 40 yo, short, brunette, average build and C cup tits and other other wife 38 yo, slim, taller maybe 5'6", short blonde hair, and small tits walk to the bathroom we discussed daring them to strip for us when they returned. They had both had a few drinks, were in playful moods, and neither seemed to mind the mild teasing we were already giving them.
When they returned we continued to tease them and paw at them and started to suggest that they get naked for the rest of the night. My wife being a little more affected by the alcohol was all for it and quickly began pleading for the other wife to strip with her. As I took my wife's bikini top and shorts off exposing her tits and hairy pussy the other wife finally relented, but only got topless at first. It wasn't until we talked them into lap dances that the other wife finally dropped her shorts and showed off her bare pussy and sexy meat curtains.
We ended up fucking them during the lap dances, but the highlight of the night was after that when we talked them into eating each other out. Seeing my wife's tongue parting her long labia was one of the hottest things I've ever witnessed. It was also great seeing her spread my wife's bush and lick her clit while she fingered her, but watching my wife eat her pussy was more of a turn on.
I was afraid my wife would be upset about it all later, but she still talks about it during sex and has said she wants to do it again. Sadly, it's hard to get some adults only time so we haven't been able to work out another trip. When it does happen again it'll be exciting to how far it goes the time around.
