This involved my first wife. I came home from work to find the door that linked our apartment to our neighbors open. Thinking that my wife was over visiting my buddy's wife, I just walked in. What a surprise. My wife was having oral sex with his wife and my buddy was pleasuring himself while watching. I was really turned on, looked at them, and started pleasuring myself too. Next thing I know, he started giving me oral, and I really enjoyed it. We started doing this on a regular basis for almost two years.
