I was wondering what you would do. I was at a party at my neighbors house with my wife the other night and she went home early. I stayed much later and fell asleep on the couch while others were in the room. I woke up some time later and there was a couple in an overstuffed chair about 10 feet away making out. I watched for a few minutes and dozed off again. When I woke up they were naked and fucking. I was aroused and so I watched. The room was dimly lit so I didnt think they knew I was awake. She was on top and her back was to me. Then they switched around and she was getting it doggy style and she was facing me. At this point I knew she could see me because her face was about 5 feet from me. I just watched her and she smiled. When they finished, I pretended I was asleep so the boyfriend wouldnt know and they went upstairs to shower. Then I left. My wife and I have a very open relationship but without permission, I didnt think I should join in. What would you do?
