Free Satellite

This happened happened around ten years ago when I was about 30 years old. Back then a lot of people used to hack satellite signals so they could get free TV and I was one of them. My In-laws saw what I had and asked if I could help them get setup too. They lived in the country a couple of hours away from my wife and me while we lived in the city so we had to plan buying all the necessary equipment and then I would go out and set it all up for them as my father-in-law was not too technical.
I purchased all the equipment for them and all that was remaining was to set a date for me to go out and do the setup and install. My father-in-law was going to go away during an upcoming long weekend with his friends which would require him coming into the city airport to catch a flight. My mother-in-law doesn't like driving into the city so he suggested driving to our place and I could drop him off at the airport and then I could drive his car back to his place. I basically would stay at my in-laws place for the whole weekend and the drive back a few days later picking him up at the airport.
The weekend arrived and we did as we planned. I was at my in-laws now with my MIL and all the equipment. They already had a satellite dish so it only took a few hours before everything was setup and working. I showed my MIL how to use the system and we started going through all the channels that were available. We came to some channels which were porn channels and my MIL was surprised with what she saw but wasn't offended by it. She wanted to watch a few minutes before we moved onto other channels. We took a break for dinner and then decided to watch a movie. It was starting to get late and she suggested we get ready for bed before we watch something else. I sleep in my underwear, which she has seen me in before, and she was in a nightgown. We watched another movie on the couch together. After it was over she asked how I would feel about watching one of the porn channels with her. She told me she knew it wasn't appropriate for us to watch it together but promised not to tell anyone if I didn't. I agreed and there I now was watching porn with my MIL. She admitted that she had only ever seen magazines but never movies and was excited watching them.
At first it was awkward but the tension soon subsided. She was making comments about the body parts she seeing and what she would like to do with them. I began making comments too and since I already got along with my MIL really well I began to realize how much more cooler it really was watching porn with her. On a couple occasions she did bring up that what we were doing would just be kept between us and had me reassure her it would, which I did.
One porn movie was the spark that caused a few things to occur. It was a woman who was on the phone talking to someone asking when he would be coming over. The scene has a guy show up and she leads him to a leaking faucet that he fixes. The woman tells him that he is a great Son-in-law for coming over and fixing the leak and asks him a few times what she can do to thank him. Each time he tells her she doesn't need to do anything. My MIL laughed saying they are like us saying anytime I helped her that the women said what she does and the guy said what I always do. The woman in the porn movie then says she has an idea and starts pulling his pants down. My MIL is intently watching as the woman beings sucking the guys cock. I made the comment that they are not exactly like us with what they are doing now. My MIL says she will do it if I want. I was caught off-guard as I didn't expect her to say that and didn't think she was serious. She begins pulling my underwear off and doing exactly what the woman in the porn movie is. My MIL begins doing exactly what she is. When the woman took all her clothes off so did my MIL. The guy in the movie began to eat her pussy out and I decided to copy him. The woman in the movie pushed the guy down on the floor and began to fuck him. My MIL did the same to me. I couldn't believe this was actually happening but I wasn't complaining. Once we finished my MIL laughed and said she knows how to thank me now.
We fell asleep for awhile but when we woke up my MIL talked to me about what happened. She told me what we did may be considered wrong but it felt so right and it shouldn't be wrong for 2 people who care so much about each other to do anything with each other. She said she never expected to go as far as we did. She then told me we have a couple more days to do anything and wants me to not hold back. She said she hopes our fantasies can become reality and is willing to do anything and she means anything. To keep this story short, she meant what she said and did more than I ever expected and definitely more than my wife would.
it was two more days of pure sexual activity before we had to go pick up my FIL.
