But doing a 40th surprise Birthday party that I gave for my wife and while she was busy with All the guest, I had a nice conversation with my neighbors wife!
Seems that the neighbors wife got a bit intoxicated and went down on my wife after a few of the guy guest made a deposit inside her! She came by me saying that my wife was extra tasty tonight for some reason?
I told her that what she was enjoying for her 1st time was the mixture of CUM and my wife's juices! The neighbors wife never let any guy CUM in her mouth and with that said, she didn't swallow it either!
Thinking that I was right, she asked me to go upstairs with her to my bedroom. It was there that she wanted to do oral on me and have me CUM in her mouth so she could find out if I was right!
I felt Bad for awhile, but my naughty side said now is your chance to be the 1st guy to CUM in her mouth!
So I did oblige her and to my surprise again, she swallowed it!

That night I after all the guest left, I told my wife about what happened and she just didn't seem to believe me!
The next morning my wife went to the neighbors house and asked if what I said was True!
My wife got the same answer that I said, but with her hubby standing there it seemed to surprise him too cause she never told him about it!
Now not wanting to be outdone by another women / Best friend on something she has never done before, my wife asked the neighbors hubby if he'll do anal sex with her now?
My wife never did anal Sex, so Us hubby's made a Trade off with our wife's! I got anal sex from his wife, then he got to CUM in my wife's mouth and she swallowed it~
So with the help of the neighbor's wife in getting my wife's Asshole ready for his cock, the hubby got to have his anal sex with my wife but didn't last too long because of the thrill he got knowing it was her 1st time at doing it~
So I'm not sure if its out of spite or revenge, but it sure worked out better for Us guys now!
