I have been trying to get my wife to try anal SEX of years, but she wouldn't do it. But late in life when we changed our lifestyle and we got to see and enjoy sharing pleasures with others as well as seeing what they do it helped out some!
But when I gave my wife a Surprise 40th Adult Birthday party it turned out to be a Blessing for both of us, for some reason women enjoy competition and don't enjoy being out done by another woman!
My wife and the neighbors wife who are Best friends too, are always trying to out do one another. But for myself and the hubby of the wife next door, we worked out a nice Trade agreement early with our wife's!
His wife doesn't like you CUM in her mouth nor swallow it, but she does Anal sex. My wife is just the opposite and won't do anal, but will let you CUM in her mouth and she'll swallow it!
So when us hubby's want to enjoy the other pleasures, we just exchange wife's for it. lol
But at my wife's 40th B/day party I didn't have any Candles on the cake, so when she asked about them I told her my plan was for her to Blow all the guys at her party instead and I made sure we had plenty of Guest too.
My wife had the entire evening and night for her task, so while taking a break from cock she enjoyed some Pussy too from the wife's of the guys! Our neighbor wife was getting so intoxicated on drinks, but at the same time she was going down and eating out my wife too. There were a few times when my wife went to clean up some of the creamy gooey mess that was leaking out of her, but a few times somebody went down on her and made that impossible. I was taking care of the Guest and doing plenty of watching too! lol
The neighbors wife came up to me and told me that my wife was tasting real good tonight, but she couldn't understand the reason for that? I told her that if she paid more attention she would have seen that some guys made their CUM deposits inside her, so besides enjoying my wife's juices she was having her 1st taste of CUM too!
She was startled by my response and thought about it for a few minutes, than she asked me to come up with her to the bedroom upstairs. Once in my bedroom she asked me to do her a favor, she wanted me to CUM in her mouth and she would swallow it. This was something that I wanted to do with her for along time, so I said sure. She locked the door and started doing oral on my bobbing cock. When I was ready to CUM, I had a change of Heart on this drunken neighbors wife and started to pull out of her mouth!
She was bound and determined to get my CUM, so she held me inside her mouth and after my deposit she kept on sucking more out of me if possible? lol
She told me that I was right, but not to tell any of the guys at the party cause she didn't want them all asking her for the same pleasure.
At the end of the night in bed with my wife, I told her about what happened and she was in disbelief about it and shocked saying she would never let anybody CUM in her mouth.
So to make sure I wasn't telling a fib, the next morning my wife rushed over to the neighbors house to ask her if it was True? Both of the neighbors were home and when my wife asked her, she replied she did let me CUM in her mouth and swallowed it! That moment even put a shock face on her hubby since she never done it before and it left my wife even speechless for the moment!
But not wanting to be outdone, my wife asked the neighbors hubby if he wanted to try Anal sex with her right now?
He said sure, so all of them went up to their bedroom and got their clothing off and a bit prepared for him to bone my wife in her tight asshole! Since I wasn't there, I would imagine they all had a great time together while my wife got it anal for her 1st time. She can home and while telling me about it, she got exposed for me and showed me his deposit leaking out of her now widen & red asshole!
Just like the neighbor hubby, I was shocked and surprised by what she done along with the neighbors wife too.
But the good part is now both of them have a change of Heart for more different pleasures, but we still have our exchange of wife's to keep the wife's Happy too~

I can just say that women for some strange reason enjoy being in competition with other women in doing anything and its great when it comes to SEX!
