STROKIN WATCHIN THE FOOTBALL GAME

I don't know what made me randy, but I was. I had taken my wife to her mother's house and we had lunch that her mother prepared. The wife's sister was also there as she lives with MIL now, as she is 90 years old. I still think MIL is in better physical shape than either daughter, and she still drives and cooks her own meals. After lunch, there was a football game on TV that I wanted to watch, and I begged off the Cribbage game, so the 3 women played Cribbage, as this Card game can be played by either partners or single players. I went into the living room and turned on the Football game, and sat down to watch. Since I am an exhibitionist, I have for many years shown off for the MIL. She was sitting at the table in the kitchen about 20 feet from me, and she was the only one of the 3 who could see me. I was behind the wall of the living room to everyone except MIL, and when I leaned back on the couch, she could not see me above the waist, but she could see what I was doing with my hands. As I watched the game, I developed an erection for some unknown reason, and began fumbling with it inside my pants and shorts. But this wasn't enough, so I unzipped, and unbuttoned the jeans, and slid them down enough so that my cock could come out without pain from the zipper, and proceeded to continue to play and stroke it. I occasionally would lean forward to see if I was being observed, and caught her looking a couple of times with a slight smile on her face. Remember I have been showing off for her for over 40 years whenever we stayed overnight. Usually just slow getting dressed in the morning while she was fixing breakfast, and appearing naked in the living room where she could see me and no one else could. A couple of other stories about this, but maybe later. Anyhow, I continued to watch the game, fondle my cock, and watch the MIL. After a bit, I realized that she had got up and was walking in my direction. She walked in front of me and went to the gas heater on the west wall, and adjusted it or acted like she adjusted it. Gave my cock a quick inspection, and gave me a big smile and went back to the kitchen to the card game. I went on watching the game, and stroking. However, I lost my concentration, and realized that I was gonna cum. I got up, just holding up my jeans, and went through the front bedroom to get to the bathroom. I could not be seen from the kitchen during this move, but when I got to the bathroom and looked through the hallway door on the other side, here was my wife's sister looking right at me and my hard on in my hand. Busted! But she didn't say a thing. She evidently was going to the bathroom, and I just happened to take that particular time to go there also. I arrived through the West door, and she came in through the South door, while admiring my hard on in my hand. She didn't hesitate. She came through the door, and closed it behind her, and as soon as the latch caught, she had her hands on my cock. She moved slightly behind me, and to my right, and very quickly finished my stroking over the bathroom lavatory, and I shot my load through her fingers into the lavatory. The quickest hand job in history. I was a bit embarrassed, even being the exhibitionist that I am, but it seemed that she was not. She sat on the stool, took her pee, washed her hands and went back to the card game. I quietly snuck back to my seat at the end of the couch. Don't know what the MIL thought of my absence at the same time that SIL was in the bathroom. Maybe she thought I was just watching her take her pee, but nothing more was ever said about the situation, and I have just never had the urge to stroke myself watching TV at MIL's house again.
