My mother in law is 49 and very attractive as is my wife, her daughter. My wife is straight laced but her mother is not. Is has always got her mind firmly in the gutter. When she stays with us in the summer she feels free to walk around after a bath in a towel, often her butt cheeks peeking out or in panties and bra. This is our fourth year here and this summer she would join me for coffees in the kitchen wearing a babydoll nightie. Often no panties and shaved crossing her legs often.
One afternoon after a very intense day of tennis, I came home and had a hot tub. It’s off our master and can only be reached through our bedroom. Wife and MIL were gone and even if not, it isn’t unusual for my to do a tub nude because our tub is out of bounds to anyone but my wife and I unless invited. I was on my third cold one when as it turned out, they were not together. My wife was out golfing and my MIL went for a long hike/walk. When she came home she walked into our bedroom and out to the tub. She could see I was nude as we spoke. She apologized and then asked if she could join in. I said sure but that I would get my suit on while she left to get into hers. Her response was, “Don’t be silly. Tubs are done nude!” She stripped down, very nice, and slipped into the tub. The water was hot and she was hotter. She asked me to get her a beer. I got up and out to the beer fridge came back as her eyes were locked in on my cock. As I bent down to hand her a beer she reached instead for my cock. She laughed and said something about drinking from my tap and then quickly put me into her mouth. I couldn’t believe it! I was rock hard fast and she gave me the most incredible blow job I have ever had. I feel bad in having let her but we fucked whenever we could and she is an animal. We both agree that her daughter can never know because it would kill us to hurt her yet I sure next summer it will be the same.
