FB's Birthday

My wife and I had a fb a few years ago, he is a friend and coworker of mine and his birthday was today which reminded me of one of his previous birthdays. I was off but had to stop at work, my wife was with me and we spotted Rob walking across the parking lot. We stopped to talk, he said it was his birthday so we invited over for lunch. We got home, dropped our clothes on the way to the bedroom so when he arrived we were naked on the bed and I was eating my wifes pussy. He shed his clothes quickly and moved in so she could suck his cock. Before long she asked the birthday boy what he wanted, he said pussy so I moved and he climbed on and slid into her pussy eventually rolling over with her on top. He pulled her off, she got on all fours so I could fuck her and she sucked his cock until he came and I unloaded in her. He had to get back to work but had a great birthday.
