It's Okay! She's My Mother in Law 3(2010)

My wife told me her mom was a big flirt and that I'd better stay away. I said, "Yes dear." When I finally met her I knew exactly what she meant. But her mom was much more than an innocent flirt, I found out personally, she was a totally smoking hot slut! But I'm not telling my wife a thing. It will be mine and her mom's dirty little family secret.
