[De and Ci]

This past weekend some we went to our favorite swinger's club with some friends. We ended sitting with another couple that we both know pretty well in the lifestyle. We have never expressed much sexual interest in them. I'm not interested in her-she's not my type, she likes my wife-she is very bisexual, my wife is not (bi-playful), she is agrees to be just friends with my wife. However, her hubby totally has the hots for my wife-he has always been somewhat pushy-always asking my wife when will she "do him". Anyway we have always kept them at arms length sexually and consider them club friends.

Well, on this particular night, he started coming on to my wife, asking what can he do for her to have sex with him, saying how sexy and hot she is, she's so beautiful, yadda yadda, basically begging. Anyway I suggested to my wife since he's been trying so hard and for so long maybe she should give him a little. She agreed so she started flirting with him, asked him to dance, dancing very suggestive to him, rubbing him, (she was wearing a very sexy dress and nothing underneath), he was getting very excited, they got back to the table, they were talking and flirting, he kept asking me if it was ok, I said go for it, maybe tonight will be his night, he was so entralled. So much that a girl friend of ours started talking to my wife, he told her "she was cutting in on his action", I explained to our friend what the deal was-she understood and we had a laugh. Anyway we invite them back to our friends house. So there are 3 couples-we all know each other. The other couple knows what the deal is-I explain that my wife is going to let him fuck her. We all end up on the bed and he can't get it up. His wife tried sucking on him, he got a little hard, went to put the rubber on and lost it, just couldn't get hard. I was suprised and a little disappointed, wanted to see him go after it. I ended up screwing my wife. After we all finished we went to the hot tub, he stayed inside, didn't want to go, and got his wife and they left shortly afterwords. I couldn't believe it, but our friends explained that sometimes that happens-he may have got nervous. But he had been begging my wife almost 2 years. Has this happened to anybody else?
I mean, he wanted her so bad, my wife said he was very hard when we were at the club. My wife thinks he's not going to want to talk to us for awhile and will be embarrased to see us. I think that he will make a bunch of excuses and will come on to my wife again. Any thoughts? Is this common?
