Cindy and Sally meet at their 30th class reunion, and they hadn't seen each other since graduation. They begin to talk and bring each other up to date. The conversation covers their husbands, their children, homes, etc. and finally gets around to their sex lives.
Cindy said, "It's okay. We get it on every week or so but it's no big adventure. How's yours?"
Sally replied, "It's just great, ever since we got into S & M."
Cindy is aghast. "Really Sally! I never would have guessed that you would go for that sort of thing."
"Oh, sure," says Sally. "He snores while I masturbate."
