Good wives do good things
I was with the wife at our friend's house watching some football with a few people. We 3 guys were watching the game while our wives were drinking wine and gossiping in the other room. They came in every once in a while to bring us appetizers and check on the score, but they were not huge fans.
My friend's wife Karen came in and asked her husband if he needed anything, and he said "a blowjob." She laughed and didn't think he was serious, but we all had his back and urged her to do it. She stood there and thought about it, and then went over to her husband and pulled out his dick and went to town. It was awesome. We cheered her on.
With all the noise my wife Ava and the other guy's wife Julie came down and initially looked aghast at the scene. We begged, and I mean begged, for our wives to give us bj's too, and reluctantly they said okay. (I thought for a moment they would deny us). My wife Ava hadn't sucked my dick in a year, and her skills were rusty. It was still good though. Of course we wanted them to rotate, but they said no. (Fuck, and I was dying to receive head from Karen or Julie; they looked so hot with cocks in their mouths). Anyway, we popped our loads down their throats and said that they were the best wives ever.
After they left my buddies and I talked about what happened, and we all agreed that we'd be up for a swap, if we could convince them. That night I brought it up to my wife and she said "I don't think so, but I'll think about it." That leaves the door open a little to the possibility. It's a longshot, but I hope it happens.
Usually in these situations.. The wife is looking at it as a whats in it for her type deal
