Would love to see my wife with a

My wife is a very sexy lady. Size 12 curvy, blonde [at the moment] nice looking, but lacks confidence in her appearance.

In her early 50's she has her own sucessful business which means thats she works long hours and that when we have some free time together we try and enjoy it rather than sleep.

She has always had admirers, when we go out she more often than not gets chatted up at the bar but she just laughs this off and most blokes when they see she is with me back off. We have a good sex life - she can throw off the prim business image and  be a slut in bed- but I have a fantasy to see her iwth another guy.

We have talked about it and there have even been some contenders -one bottled it another got too drunk lol. These bad experiences have put her off although she has fllirted and performed sex acts on other guys when she has had rather too many drinks. Red wine sends her over the edge and she loses her inhibitions - more often than not she also loses some of her memory of events.

I know this may be a common fantasy and it may end up just being that, but i know that deep down she would like to try someone else. She has started to get texts from a business client of hers -asking her for a drink and perhaps more - should I push her into accepting? His next visit to the area is next week - should she go for lunch or dinner?
