My wife, her sister and mother look very much alike. They are very close and being European, free with their nudity. I have seen them nude many times. Usually sunbathing but it's nothing for me to be over at my in laws home and have my wife's mother come out of the bathroom or bedroom stark naked and pour a cup or coffee or get a Coke. It happens so often that I don't even raise an eyebrow. A dick, yes. But never an eyebrow.
We've been married for thirteen years. A second marriage for both of us. My father in law passed away six years back. A great man. My sister in law has lived with several men but never got married and hasn't any children. We have a large home and it's not unusual for mother and sister in law to stay over.
After a particularly hard day at work I came home to the three of them in our hot tub. It was apparent that they had been into the wine. All of them acting very silly. I decided to get naked as well, took out a cold beer and joined them. Not a first time.
We talked and laughed telling stories. My sister in law sitting beside me place her hand around my cock. "I haven't one of these in a long while!" she said, laughingly. My wife laughed as well as my mother in law who added, neither have I.
My sister in law didn't let go. She played me until I got hard with my wife seemingly not minding. I got a little uncomfortable and got out of the tub to get another beer. My mother in law and sister in law made comment about how beautiful my erection was and how lucky my wife was to have it. This was getting nuts. They said while you're up (laughter) get us more wine which I did. Not that they needed it. My erection was still intact when I got back, again with the glowing comments.
My wife seemed very proud of my penis. My mother in law moved to one side of me and my sister in law the other. Obviously very tipsy, my mother in law was now playing with my hard on soon joined by my sister in law. My sister in law said to my wife, you must share the wealth sister with her laughing and then agreeing with their statement!
