My Wife Screwed Our Overnight Guest, and Started New Fun for Both of Us My wife and I had an old friend (Les) stay with us a couple of nights while he was working in our area. It was when we went to bed on the last night of his visit that my wife surprised me by going down on me, and giving me a great head job. As I got excited and started to touch her, she stopped me and said she was going to Les's bed for a fuck, and told me I had to stay in our bed. I blew almost immediately, but fortunately not on her. She got straight out our bed and went to the room Les was using. I tiptoed down the passage, but the door was shut, so I went outside. Luckily, I was able to watch my wife in bed with Les through a crack in the curtain. I've got to tell you, it was amazing to watch them together. Although the covers concealed them most of the time, I did get a glimpse of his cock inside her as she rode him. They played for what seemed like ages, giving me a whole heap of emotion to deal with. The emotion was mostly lust. I was so turned-on by my wife's brazen act! When I woke up in the morning, my wife was beside me, snuggling up to my back. She asked if I was upset by what she had done, and begged forgiveness. When I told her that what she had done excited me, her mood changed straight away. She told me how lovely the sex with Les was, and said she hoped I really was okay with it, as she gave me a passionate kiss. That was the start of inviting other men entering our shared sex life, and the start of a whole lot of fun for both of us.
