The caption certainly sounds like one of mine. It's been in my files a long time. If it isn't, then apologies to the author and my kudos for a good caption. I admit to being fascinated by the idea of a mother in law being in on the domination. Really funny sense my first would be mother in law died just before we were married and I would have greatly resented her interference, but then it wouldn't have had a sexual component at all.
