Earlier in our marriage a single buddy of mine used to hang out with us and I used to tease my wife about wanting to fuck him. She admitted he was cute and said maybe she would, I told her to go ahead. One Friday night he stopped by, I was tired from a long week but we had a few beers and I fell asleep. I woke up, the lights were off except the tv, I looked around and she was riding him on the couch. I stayed still and finally heard him unloading in her, they collapsed a while until he got up, got dressed and she walked him out and came to wake me. I asked if she enjoyed herself, told her I wasn't mad but horny as hell. We went to bed, I was inside her soaked pussy in no time and she told me about it. They had a couple more beers, got a little buzzed and started tossing popcorn at each other and one landed in his lap. He told her to come and get it, she nibbled his dick, kissed him and soon had his dick out sucking it. She couldn't believe how hung he was and wanted his cock by the time she got him hard, pealed her clothes off and climbed on. She said she came 4 times before he shot a huge load in her. By that time I exploded in her and she was oozing cum. We never had a threesome but she gave him a blowjob once while we were driving home from a party one night. They had a few more sessions until he eventually got engaged each time telling me about it while we had sex.
