You brought up the idea of 3somes with your wife. At first she thought you were crazy. But you mentioned to her that a couple of your friends had compliment you on having a wife with such a nice ass and hips. She questioned you about the compliment. You told her, "Yea a couple of the guys from that superbowl party mention it. I know they'd give anything to see your bare ass".
You could tell she was curious, so you pushed it a little. "If we did get into a threesome, I'd be there. And I know Carl and Jerry would be the guys to invite. Keep in mind if we get both of them you'd be working with 3 cocks. And since they love those hips so much, they'll be fucking you doggy".
Well the time came and sure enough, she knew her ass was the main attraction. They would hold your wife's tiny hips as they plunged their cocks into her pussy.
