Did my mother in law

Last spring break the kids were at the coast with friends and my wife was working evenings the whole week. I came home one night after a hard day at work, fixed me a sandwich and drink, ate, and figured I would relax in the hot tub since I had the house to myself. I stripped, grabbed a towel and climbed into the hot tub which is on our back patio. As I got into the water, I closed my eyes and leaned my head back against the side. A few minutes later I hear ?you asleep?? I looked up and there was my mother in law standing next to the hot tub looking down at me. She lives several blocks from us and has a key to the house.

Thinking fast I said ?just relaxing?. She said she knew I would be by myself and stopped by to see if I wanted to go have dinner. I told her I just ate, but she was welcome to come join me if she wanted. Then she shocked me by saying ?I think I will!? She then went back into the house. So for a minute I sitting naked in the hot tub thinking is she coming back? A few minutes later, she comes out of the house with a bathrobe on and carrying a towel. She then put the towel down and took off her robe and started to climb into the tub naked. I had never seen my mother in law naked and we never had talked about sex.

My mother in law is 63, a retired government high school teacher. I never thought of her in a sexual way, but here she was naked climbing into the tub with me. As she stepped over the side, I reached up and grabbed her hand and placed my other hand on her hip to help in. As she got into the water, I was trying to act calm and hide my now raging hard on. To me my mother in law was one of those people you would not pay much attention if you saw her in a store, but here she was naked sitting across from me. Our legs would rub against each other sometimes in the water.

We talked about little things, work, kids, how the water felt etc? After about fifteen minutes she said she need to get out and ?cool down.? As she stood up, I again grabbed her arm and hip to help her out of the water. As she got out of the water, I figured why not and got out of the tub. She grabbed a towel and placed her face into it while facing away from me. I grabbed my towel and walked up to her back and stuck my hard on in the crack of her ass and started drying her back off. She then turned around, grabbed my hard on and looked me in the eye and said ?someone happy to see me.? I could only respond back ?I think so!? She responded back ?let go inside!? She turned and went into the house and I followed her to my bedroom. She climbed up on the bed, got on her back, opened her arms and said ?well come here!? I was now in total shock and figured why not. I climbed on top of her and went straight in, no fore play, I was ready! She gave me a great french kiss, I grabbed one of her breasts, I pushed hard and did not last long. I exploded inside her. Both our eyes were forced shut because we both came at the same time.

After we just laid there for a while and then started talking. She shocked me even more and told me she and my father in law had done swinging in the past. I didn?t let on that I had also, but we talked about not telling my wife about that night, but maybe in the future having her come over and join us in the tub.
