My wife was going out with her sister, mother and some other women for a girls movie night and said she would be staying overnight at her sisters. Her sister picked her up at around 8:00pm and off they went. After they left I got undressed like I usually do and was naked. I began to watch TV and must have fallen asleep. I woke up to find my wife, her sister, her mother, a few of her friends and a few other women I had never met standing over over. There was 9 of them and me on my back naked with it all exposed to them. Since I had just woken up I had an erection too which made things a little more embarassing. Two of them were taking pictures of me and my wife was laughing her head off as were some of the other women. They were making comments about the situation like how this is much better than going to a movie and now they can see why my wife married me. I asked why they weren't at the movie and was told it sold out. It was my mother-in-law who said they better let me go and get dressed and grabbed me by the hand and lead me out of the room. What was really awkward was when she was leading me she suddenly stopped and she said she never expected to see me this way. She then placed her hand on one of my ass cheeks and while grabbing and squeezing it took her other hand and wrapped it around my cock telling me it was a bonus to see my cock erect too. She then said she doesn't get the chance to see guys naked anymore let alone her son-in-law. She then added that we will need to do this again, and alot more, when we are alone. She then winked at me and left me to get dressed.
