A buddy of mine from work was in a bad marriage and one night while on a business trip with my wife and we had a great threesome. We all got comfortable together and meshed well, we both have slightly above average cocks and my wife enjoyed his big knob. One day I was off but had to stop at work when we saw him walking across the parking lot. We stopped to talk and found out it was his birthday so we invited him over for lunch. We got home and left a trail of clothes to the bedroom, when we heard the door open we were in bed naked. When he entered the bedroom she asked what he wanted for his birthday, walked over and kissed him while taking his clothes off. She led him to the bed and started sucking his cock while I licked her pussy until she came. She laid him down and climbed on gasping a little as his knob entered her. I watched for awhile until I could tell he needed a break, laid down so she could mount me and get us near the edge so she could suck him some more. After awhile he said he wanted his present and walked behind us guiding his cock in next to mine, she resisted a little but was wet as hell from cumming 3 times and soon he was in and we were both sliding in and out. Before long I said I was going to cum, he said me too and I felt a gush of hot jiz soaking her pussy. I exploded too and we all sort of relaxed until his dick started going limp and slid out oozing cum all over me. We all showered together and ate lunch naked before he got dressed and went back to work.
