My wife and I were going at it real stong one afternoon and man is she moaning and groaning and I'm thinking to myself, I must be some more man so I put her legs up at my neck and the moaning gets louder now I go into high gear and she is almost screaming. After I finish I roll off of her and say well babe it sounded like you really must have enjoyed that and she ask why I said that. To which I reply you were moaning and screaming so I guessed you were really enjoying it. She looks me square in the eyes and said I had the worst cramp.
