My wife and I had done a 3 some with a friend of mine a few times. I could see he had a bigger cock, and by watching my wife, when they fucked, I could tell he was better then me also. One night as my wife and I laid in bed, she had told me that my friend had had a "bad experience" with his brother when they were young, and that "he didn't want to do 3somes anymore". "He just wants it to be the two of us." I asked her "is this what you want"? And she said "yes". After she said that, all I could say was "ok". I eventually figured out that he had been coming over and fucking my wife while I was at work. After that, whenever he'd come over, even when I was home, my wife would take his hand and walk him to the bed room, and I'd sit in the living room while they fucked. But that night she told me no more 3somes, and this is what she wanted, still plays over in my mind, and gets my little pee pee hard.
